Old Changelog
Changes done to curl and libcurl from 1997 to 2010, edited manually. The most
recent changes are always generated into the CHANGES file straight from git.
Kamil Dudka (17 June 2010)
- Improve test575 in order to not fail with threaded DNS resolver.
Version 7.21.0 (16 June 2010)
Daniel Stenberg (5 June 2010)
- Constantine Sapuntzakis fixed a case of spurious SSL connection aborts using
libcurl and OpenSSL. "I tracked it down to uncleared error state on the
OpenSSL error stack - patch attached deals with that."
Daniel Stenberg (5 June 2010)
CURLINFO_LOCAL_PORT to curl_easy_getinfo().
Yang Tse (4 June 2010)
- Enabled OpenLDAP support for cygwin builds. This support was disabled back
in 2008 due to incompatibilities between OpenSSL and OpenLDAP headers.
cygwin's OpenSSL 0.9.8l and OpenLDAP 2.3.43 versions on cygwin 1.5.25
allow building an OpenLDAP enabled libcurl supporting back to Windows 95.
Removed the non-functional CURL_LDAP_HYBRID code and references.
Daniel Stenberg (2 June 2010)
- Jason McDonald posted bug report #3006786 when he found that the SFTP code
didn't timeout properly in several places in the code even if a timeout was
set properly.
Based on his suggested patch, I wrote a different implementation that I
think addressed the issue better and also uses the connect timeout for the
initial part of the SSH/SFTP done during the "protocol connect" phase.
Yang Tse (2 June 2010)
- Added missing new libcurl files to non-configure targets. Adjusted
libcurl standard internal header inclusions in new files. Fixed an
SPNEGO related memory leak. Fixed several LDAP related compilation
issues, and fixed some compiler warnings.
Daniel Stenberg (1 June 2010)
- Igor Novoseltsev reported a problem with the multi socket API and using
timeouts and timers. It boiled down to a problem with libcurl's use of
GetTickCount() interally to figure out the current time, while Igor's own
application code used another function call.
It made his app call the socket API timeout function a bit _before_ libcurl
would consider the timeout to trigger, and that could easily lead to
timeouts or stalls in the app. It seems GetTickCount() in general often has
no better resolution than 16ms and switching to the alternative function
QueryPerformanceCounter has its share of problems:
We address this problem by simply having libcurl treat timers that already
has occured or will occur within 40ms subject for treatment. I'm confident
that there are other implementations and operating systems with similarly in
accurate timer functions so it makes sense to have applied generically and I
don't believe we sacrifice much by adding a 40ms inaccuracy on these
Kamil Dudka (27 May 2010)
- added a new test for CRL support (test313)
- Tor Arntsen changed the alternative definition of bool to use enum instead
of unsigned char.
Daniel Stenberg (25 May 2010)
- Julien Chaffraix fixed the warning seen when compiling lib/rtmp.c: one
unused variables, several unused arguments and some missing #include.
- Julien Chaffraix fixed 2 OOM errors: a missing NULL-check in
lib/http_negociate.c and a potential NULL dereferencing in lib/splay.c
- Howard Chu brought a patch that makes the LDAP code much cleaner, nicer and
in general being a better libcurl citizen. If a new enough OpenLDAP version
is detect, the new and shiny lib/openldap.c code is then used instead of the
old cruft.
Daniel Stenberg (21 May 2010)
- Eric Mertens posted bug #3003705: when we made TFTP use the correct timeout
option when sent to the server (fixed May 18th 2010) it became obvious that
libcurl used invalid timeout values (300 by default while the RFC allows
nothing above 255). While of course it is obvious that as TFTP has worked
thus far without being able to set timeout at all, just removing the setting
wouldn't make any difference in behavior. I decided to still keep it (but
fix the problem) as it now actually allows for easier (future) customization
of the timeout.
- Douglas Kilpatrick filed bug report #3004787 and pointed out that the TFTP
code didn't handle block id wraps correctly. His suggested fix inspired the
fix I committed.
Daniel Stenberg (20 May 2010)
- Tanguy Fautre brought a fix to allow curl to build with Microsoft VC10.
Daniel Stenberg (18 May 2010)
- Eric Mertens posted bug report #3003005 pointing out that the libcurl TFTP
code was not sending the timeout option properly to the server, and
suggested a fix.
Kamil Dudka (16 May 2010)
- Pavel Raiskup introduced a new option CURLOPT_FNMATCH_DATA in order to pass
a custom data pointer to the callback specified by CURLOPT_FNMATCH_FUNCTION.
Daniel Stenberg (14 May 2010)
- John-Mark Bell filed bug #3000052 that identified a problem (with an
associated patch) with the OpenSSL handshake state machine when the multi
interface is used:
Performing an https request using a curl multi handle and using select or
epoll to wait for events results in a hang. It appears that the cause is the
fix for bug #2958179, which makes ossl_connect_common unconditionally return
from the step 2 loop when fetching from a multi handle.
When ossl_connect_step2 has completed, it updates connssl->connecting_state
to ssl_connect_3. ossl_connect_common will then return to the caller, as a
multi handle is in use. Eventually, the client code will call
curl_multi_fdset to obtain an updated fdset to select or epoll on. For https
requests, curl_multi_fdset will cause https_getsock to be called.
https_getsock will only return a socket handle if the connecting_state is
ssl_connect_2_reading or ssl_connect_2_writing. Therefore, the client will
never obtain a valid fdset, and thus not drive the multi handle, resulting
in a hang.
- Sebastian V reported bug #3000056 identifying a problem with redirect
following. It showed that when curl followed redirects it didn't properly
ignore the response body of the 30X response if that response was using
compressed Content-Encoding!
Daniel Stenberg (12 May 2010)
- Howard Chu brought support for RTMP. This is powered by the underlying
librtmp library. It supports a range of variations and "sub-protocols"
within the RTMP family.
- Pavel Raiskup brought support for FTP directory wildcard matching to allow
selective downloading. To provide that, a set of new options were added:
There were also a set of new tests added (574 - 577) to verify this.
Kamil Dudka (11 May 2010)
- CRL support in libcurl-NSS has been completely broken. Now it works. Original
bug report:
Daniel Stenberg (7 May 2010)
- Dirk Manske reported a regression. When connecting with the multi interface,
there were situations where libcurl wouldn't store connect time correctly as
it used to (and is documented to) do.
Using his fine sample program we could repeat it, and I wrote up test case
573 using that code. The problem does not easily show itself using the local
test suite though.
The fix, also as suggested by Dirk, is a bit on the ugly side as it adds yet
another call to Curl_verboseconnect() and setting the TIMER_CONNECT time.
That situation is subject for some closer inspection in the future.
- Howard Chu split the I/O handling functions into private handlers.
Howard Chu brought the bulk work of this patch that properly moves out the
sending and recving of data to the parts of the code that are properly
responsible for the various ways of doing so.
Daniel Stenberg assisted with polishing a few bits and fixed some minor
flaws in the original patch.
Another upside of this patch is that we now abuse CURLcodes less with the
"magic" -1 return codes and instead use CURLE_AGAIN more consistently.
Daniel Stenberg (5 May 2010)
- Hoi-Ho Chan introduced support for using the PolarSSL library. You control
this with the new configure option --with-polarssl.
Daniel Stenberg (29 Apr 2010)
- Ben Greear made telnet a lot better/easier to use by an application:
The main change is to allow input from user-specified methods, when they are
specified with CURLOPT_READFUNCTION. All calls to fflush(stdout) in
telnet.c were removed, which makes using 'curl telnet://' painful
since prompts and other data are not always returned to the user promptly.
Use 'curl --no-buffer telnet://' instead. In general, the user
should have their CURLOPT_WRITEFUNCTION do a fflush for interactive use.
Also fix assumption that reading from stdin never returns < 0.
Old code could crash in that case.
Call progress functions in telnet main loop.
Daniel Stenberg (26 Apr 2010)
- Make use of the libssh2_init/exit functions that libssh2 added in version
1.2.5. Using them will improve how libcurl works in threaded situations when
SCP and SFTP are transfered.
Daniel Stenberg (25 Apr 2010)
- Based on work by Kamil Dudka, I've introduced the new configure option
--enable-threaded-resolver. When used, the configure script will check for
pthreads and if around, it will build libcurl to use pthreads to do name
resolving in a threaded manner. Note that this is just a fix to offer an
option that can enable the code that already included. The threader resolver
code was mostly added on Jan 26 2010.
Daniel Stenberg (24 Apr 2010)
- Alex Bligh introduced the --proto and -proto-redir options that limit what
protocols curl accepts for the requests and when following redirects.
Kamil Dudka (24 Apr 2010)
- Fixed test536 in order to not fail with threaded DNS resolver and tweaked
comments in certain examples using curl_multi_fdset().
- Fixed SSL handshake timeout underflow in libcurl-NSS, which caused test405
to hang on a slow machine.
Daniel Stenberg (21 Apr 2010)
- The -O option caused curl to crash on windows and DOS due to the tool
writing out of boundary memory.
Yang Tse (20 Apr 2010)
- Ruslan Gazizov detected that MSVC makefiles were using wsock32.lib instead
of ws2_32.lib, this generated linking issues on MSVC IPv6 enabled builds
that were done using those makefiles.
Daniel Stenberg (19 Apr 2010)
- -J/--remote-header-name didn't strip trailing carriage returns or linefeeds
properly, so they could be used in the file name.
Daniel Stenberg (16 Apr 2010)
- Jerome Vouillon made the GnuTLS SSL handshake phase non-blocking.
- The recent overhaul of the SSL recv function made the GnuTLS specific code
treat a zero returned from gnutls_record_recv() as an error, and this caused
our HTTPS test cases to fail. We leave it to upper layer code to detect if
an EOF is a problem or not.
- I reverted the resolver fix from yesterday and instead removed all uses of
AI_CANONNAME all over libcurl and made the only user of that info (krb5.c)
use the host name from the URL instead. No reverse resolving is a good
- Paul Howarth made configure properly detect GSS "on ancient Linux distros"
by editing in which order we use headers to detect GSS.
Daniel Stenberg (15 Apr 2010)
- Rainer Canavan filed bug report #2987196 that identified libcurl doing
unnecesary reverse name lookups in many cases when built to use IPv4 and
getaddrinfo(). The logic for ipv6 is now used for ipv4 too.
Version 7.20.1 (14 April 2010)
Daniel Stenberg (9 Apr 2010)
- Prefixing the FTP quote commands with an asterisk really only worked for the
postquote actions. This is now fixed and test case 227 has been extended to
Kamil Dudka (4 Apr 2010)
- Eliminated a race condition in Curl_resolv_timeout().
- Refactorized interface of Curl_ssl_recv()/Curl_ssl_send().
- libcurl-NSS now provides more accurate messages and error codes in case of
client certificate problem. Either during connection, or transfer phase.
Daniel Stenberg (1 Apr 2010)
- Matt Wixson found and fixed a bug in the SCP/SFTP area where the code
treated a 0 return code from libssh2 to be the same as EAGAIN while in
reality it isn't. The problem caused a hang in SFTP transfers from a
MessageWay server.
Daniel Stenberg (28 Mar 2010)
- Ben Greear: If you pass a URL to pop3 that does not contain a message ID as
part of the URL, it would previously ask for 'INBOX' which just causes the
pop3 server to return an error.
Now libcurl treats en empty message ID as a request for LIST (list of pop3
message IDs). User's code could then parse this and download individual
messages as desired.
Daniel Stenberg (27 Mar 2010)
- Ben Greear brought a patch that from now on allows all protocols to specify
name and user within the URL, in the same manner HTTP and FTP have been
allowed to in the past - although far from all of the libcurl supported
protocls actually have that feature in their URL definition spec.
Daniel Stenberg (26 Mar 2010)
- Ben Greear brought code that makes the rate limiting code for the easy
interface a bit smoother as it introduces sub-second sleeps during it and it
also takes the buffer sizes into account.
Daniel Stenberg (24 Mar 2010)
- Bob Richmond: There's an annoying situation where libcurl will read new HTTP
response data from a socket, then check if it's a timeout if one is set. If
the last packet received constitutes the end of the response body, libcurl
still treats it as a timeout condition and reports a message like:
"Operation timed out after 3000 milliseconds with 876 out of 876 bytes
It should only a timeout if the timer lapsed and we DIDN'T receive the end
of the response body yet.
- Christopher Conroy fixed a problem with RTSP and GET_PARAMETER reported
to us by Massimo Callegari. There's a new test case 572 that verifies this
- The 'ares' subtree has been removed from the source repository. It was
always a separate project that sort of piggybacked on the curl project since
the dawn of times and now the time has come for it to go stand on its own
legs and continue living its own life. All details on c-ares and its new
source code repository is found at
Daniel Stenberg (23 Mar 2010)
- Kenny To filed the bug report #2963679 with patch to fix a problem he
experienced with doing multi interface HTTP POST over a proxy using
PROXYTUNNEL. He found a case where it would connect fine but bits.tcpconnect
was not set correct so libcurl didn't work properly.
- Akos Pasztory filed debian bug report #572276 mentioning a problem
with a resource that returns chunked-encoded _and_ with a Content-Length
and libcurl failed to properly ignore the latter information.
- Hauke Duden provided an example program that made the multi interface crash.
His example simply used the multi interface and did first one FTP transfer
and after completion it used a second easy handle and did another FTP
transfer on the same FTP server.
This triggered a bug in the "delayed easy handle kill" system that curl
uses: when an FTP connection is left alive it must keep an easy handle
around internally - only for the purpose of having an easy handle when it
later disconnects it. The code assumed that when the easy handle was removed
and an internal reference was made, that version could be killed later on
when a new easy handle came using the same connection. This was wrong as
Hauke's example showed that the removed handle wasn't killed for real until
later. This caused a double close attempt => segfault.
Daniel Stenberg (22 Mar 2010)
- Thomas Lopatic fixed the alarm()-based DNS timeout:
Looking at the code of Curl_resolv_timeout() in hostip.c, I think that in
case of a timeout, the signal handler for SIGALRM never gets removed. I
think that in my case it gets executed at some point later on when execution
has long left Curl_resolv_timeout() or even the cURL library.
The code that is jumped to with siglongjmp() simply sets the error message
to "name lookup timed out" and then returns with CURLRESOLV_ERROR. I guess
that instead of simply returning without cleaning up, the code should have a
goto that jumps to the spot right after the call to Curl_resolv().
Kamil Dudka (22 Mar 2010)
- Douglas Steinwand contributed a patch fixing insufficient initialization in
Daniel Stenberg (21 Mar 2010)
- Ben Greear improved TFTP: the error code returning and the treatment
of TSIZE == 0 when uploading.
- We've switched from CVS to git. See
Kamil Dudka (19 Mar 2010)
- Improved Curl_read() to not ignore the error returned from Curl_ssl_recv().
Daniel Stenberg (15 Mar 2010)
- Constantine Sapuntzakis brought a patch:
The problem mentioned on Dec 10 2009
( was only partially fixed.
Partially because an easy handle can be associated with many connections in
the cache (e.g. if there is a redirect during the lifetime of the easy
handle). The previous patch only cleaned up the first one. The new fix now
removes the easy handle from all connections, not just the first one.
Daniel Stenberg (6 Mar 2010)
- Ben Greear brought a patch that fixed the rate limiting logic for TFTP when
the easy interface was used.
Daniel Stenberg (5 Mar 2010)
- Daniel Johnson provided fixes for building curl with the clang compiler.
Yang Tse (5 Mar 2010)
- Constantine Sapuntzakis detected and fixed a double free in builds done
with threaded resolver enabled (Windows default configuration) that would
get triggered when a curl handle is closed while doing DNS resolution.
Daniel Stenberg (2 Mar 2010)
- [Daniel Johnson] I've been trying to build libcurl with clang on Darwin and
ran into some issues with the GSSAPI tests in The tests first
try to determine the include dirs and libs and set CPPFLAGS and LIBS
accordingly. It then checks for the headers and finally sets LIBS a second
time, causing the libs to be included twice. The first setting of LIBS seems
redundant and should be left out, since the first part is otherwise just
about finding headers.
My second issue is that 'krb5-config --libs gssapi' on Darwin is less than
useless and returns junk that, while it happens to work with gcc, causes
clang to choke. For example, --libs returns $CFLAGS along with the libs,
which is really retarded. Simply setting 'LIBS="$LIBS -lgssapi_krb5
-lresolv"' on Darwin is sufficient.
- Based on patch provided by Jacob Moshenko, the transfer logic now properly
makes sure that when using sub-second timeouts, there's no final bad 1000ms
wait. Previously, a sub-second timeout would often make the elapsed time end
up the time rounded up to the nearest second (e.g. 1s for 200ms timeout)
- Andrei Benea filed bug report #2956698 and pointed out that the
CURLOPT_CERTINFO feature leaked memory due to a missing OpenSSL function
call. He provided the patch to fix it too.
- Markus Duft pointed out in bug #2961796 that even though Interix has a
poll() function it doesn't quite work the way we want it so we must disable
it, and he also provided a patch for it.
- Made the pingpong timeout code properly deal with the response timeout AND
the global timeout if set. Also, as was reported in the bug report #2956437
by Ryan Chan, the time stamp to use as basis for the per command timeout was
not set properly in the DONE phase for FTP (and not for SMTP) so I fixed
that just now. This was a regression compared to 7.19.7 due to the
conversion of FTP code over to the generic pingpong concepts.
Daniel Stenberg (1 Mar 2010)
- Ben Greear provided an update for TFTP that fixes upload.
- Wesley Miaw reported bug #2958179 which identified a case of looping during
OpenSSL based SSL handshaking even though the multi interface was used and
there was no good reason for it.
Daniel Stenberg (26 Feb 2010)
- Pat Ray in bug #2958474 pointed out an off-by-one case when receiving a
chunked-encoding trailer.
Daniel Fandrich (25 Feb 2010)
- Fixed a couple of out of memory leaks and a segfault in the SMTP & IMAP code.
Yang Tse (25 Feb 2010)
- I fixed bug report #2958074 indicating
( that curl on Windows with
option --trace-time did not use local time when timestamping trace lines.
This could also happen on other systems depending on time souurce.
Patrick Monnerat (22 Feb 2010)
- Proper handling of STARTTLS on SMTP, taking CURLUSESSL_TRY into account.
- SMTP falls back to RFC821 HELO when EHLO fails (and SSL is not required).
- Use of true local host name (i.e.: via gethostname()) when available, as
default argument to SMTP HELO/EHLO.
- Test case 804 for HELO fallback.
Daniel Stenberg (20 Feb 2010)
- Fixed the SMTP compliance by making sure RCPT TO addresses are specified
properly in angle brackets. Recipients provided with CURLOPT_MAIL_RCPT now
get angle bracket wrapping automatically by libcurl unless the recipient
starts with an angle bracket as then the app is assumed to deal with that
properly on its own.
- I made the SMTP code expect a 250 response back from the server after the
full DATA has been sent, and I modified the test SMTP server to also send
that response. As usual, the DONE operation that is made after a completed
transfer is still not doable in a non-blocking way so this waiting for 250
is unfortunately made blockingly.
Yang Tse (14 Feb 2010)
- Overhauled test suite getpart() function. Fixing potential out of bounds
stack and memory overwrites triggered with huge test case definitions.
Daniel Stenberg (13 Feb 2010)
- Martin Hager reported and fixed a problem with a missing quote in libcurl.m4
- Tom Donovan fixed the CURL_FORMAT_* defines when building with cmake.
Daniel Stenberg (12 Feb 2010)
- Jack Zhang reported a problem with SMTP: we wrongly used multiple addresses
in the same RCPT TO line, when they should be sent in separate single
commands. I updated test case 802 to verify this.
- I also fixed a bad use of my_setopt_str() of CURLOPT_MAIL_RCPT in the curl
tool which made it try to output it as string for the --libcurl feature
which could lead to crashes.
Yang Tse (11 Feb 2010)
- Steven M. Schweda fixed VMS builder bad behavior when used in a batch job,
removed obsolete and and updated VMS readme.
Version 7.20.0 (9 February 2010)
Daniel Stenberg (9 Feb 2010)
- When downloading compressed content over HTTP and the app asked libcurl to
automatically uncompress it with the CURLOPT_ENCODING option, libcurl could
wrongly provide the callback with more data than the maximum documented
amount. An application could thus get tricked into badness if the maximum
limit was trusted to be enforced by libcurl itself (as it is documented).
This is further detailed and explained in the libcurl security advisory
20100209 at
Daniel Fandrich (3 Feb 2010)
- Changed the Watcom makefiles to make them easier to keep in sync with since that can't be included directly.
Yang Tse (2 Feb 2010)
- Symbol CURL_FORMAT_OFF_T now obsoleted, will be removed in a future release,
symbol will not be available when building with CURL_NO_OLDIES defined. Use
of CURL_FORMAT_CURL_OFF_T is preferred since 7.19.0
Daniel Stenberg (1 Feb 2010)
- Using the multi_socket API, it turns out at times it seemed to "forget"
connections (which caused a hang). It turned out to be an existing (7.19.7)
bug in libcurl (that's been around for a long time) and it happened like
The app calls curl_multi_add_handle() to add a new easy handle, libcurl will
then set it to timeout in 1 millisecond so libcurl will tell the app about
The app's timeout fires off that there's a timeout, the app calls libcurl as
we so often document it:
do {
res = curl_multi_socket_action(... TIMEOUT ...);
And this is the problem number one:
When curl_multi_socket_action() is called with no specific handle, but only
a timeout-action, it will *only* perform actions within libcurl that are
marked to run at this time. In this case, the request would go from INIT to
CONNECT and return CURLM_CALL_MULTI_PERFORM. When the app then calls libcurl
again, there's no timer set for this handle so it remains in the CONNECT
state. The CONNECT state is a transitional state in libcurl so it reports no
sockets there, and thus libcurl never tells the app anything more about that
easy handle/connection.
libcurl _does_ set a 1ms timeout for the handle at the end of
multi_runsingle() if it returns CURLM_CALL_MULTI_PERFORM, but since the loop
is instant the new job is not ready to run at that point (and there's no
code that makes libcurl call the app to update the timout for this new
timeout). It will simply rely on that some other timeout will trigger later
on or that something else will update the timeout callback. This makes the
bug fairly hard to repeat.
The fix made to adress this issue:
We introduce a loop in lib/multi.c around all calls to multi_runsingle() and
simply check for CURLM_CALL_MULTI_PERFORM internally. This has the added
benefit that this goes in line with my long-term wishes to get rid of the
CURLM_CALL_MULTI_PERFORM all together from the public API.
The downside of this fix, is that the counter we return in 'running_handles'
in several of our public functions then gets a slightly new and possibly
confusing behavior during times:
If an app adds a handle that fails to connect (very quickly) it may just
as well never appear as a 'running_handle' with this fix. Previously it
would first bump the counter only to get it decreased again at next call.
Even I have used that change in handle counter to signal "end of a
transfer". The only *good* way to find the end of a individual transfer
is calling curl_multi_info_read() to see if it returns one.
Of course, if the app previously did the looping before it checked the
counter, it really shouldn't be any new effect.
Yang Tse (26 Jan 2010)
- Constantine Sapuntzakis' and Joshua Kwan's work done in the last four months
relative to the asynchronous DNS lookups, along with with some integration
adjustments I have done are finally committed to CVS.
Currently these enhancements will benefit builds done using c-ares on any
platform as well as Windows builds using the default threaded resolver.
This release does not make generally available POSIX threaded DNS lookups
yet. There is no configure option to enable this feature yet. It is possible
to experimantally try this feature running configure with compiler flags that
make simultaneous definition of preprocessor symbols USE_THREADS_POSIX and
HAVE_PTHREAD_H, as well as whatever reentrancy compiler flags and linker ones
are required to link and properly use pthread_* functions on each platform.
Daniel Stenberg (26 Jan 2010)
- Mike Crowe made libcurl return CURLE_COULDNT_RESOLVE_PROXY when it is the
proxy that cannot be resolved when using c-ares. This matches the behaviour
when not using c-ares.
Björn Stenberg (23 Jan 2010)
- Added a new flag: -J/--remote-header-name. This option tells the
-O/--remote-name option to use the server-specified Content-Disposition
filename instead of extracting a filename from the URL.
Daniel Stenberg (21 Jan 2010)
- Chris Conroy brought support for RTSP transfers, and with it comes 8(!) new
libcurl options for controlling what to get and how to receive posssibly
interleaved RTP data.
Daniel Stenberg (20 Jan 2010)
- As was pointed out on the http-state mailing list, the order of cookies in a
HTTP Cookie: header _needs_ to be sorted on the path length in the cases
where two cookies using the same name are set more than once using
(overlapping) paths. Realizing this, identically named cookies must be
sorted correctly. But detecting only identically named cookies and take care
of them individually is harder than just to blindly and unconditionally sort
all cookies based on their path lengths. All major browsers also already do
this, so this makes our behavior one step closer to them in the cookie area.
Test case 8 was the only one that broke due to this change and I updated it
Daniel Stenberg (19 Jan 2010)
- David McCreedy brought a fix and a new test case (129) to make libcurl work
again when downloading files over FTP using ASCII and it turns out that the
final size of the file is not the same as the initial size the server
reported. This is very common since servers don't take the newline
conversions into account.
Kamil Dudka (14 Jan 2010)
- Suppressed side effect of OpenSSL configure checks, which prevented NSS from
being properly detected under certain circumstances. It had been caused by
strange behavior of pkg-config when handling PKG_CONFIG_LIBDIR. pkg-config
distinguishes among empty and non-existent environment variable in that case.
Daniel Stenberg (12 Jan 2010)
- Gil Weber reported a peculiar flaw with the multi interface when doing SFTP
transfers: curl_multi_fdset() would return -1 and not set and file
descriptors several times during a transfer of a single file. It turned out
to be due to two different flaws now fixed. Gil's excellent recipe helped me
nail this.
Daniel Stenberg (11 Jan 2010)
- Made sure that the progress callback is repeatedly called at a regular
interval even during very slow connects.
- The tests/ script now checks to see if the test case that runs is
present in the tests/data/ and outputs a notice message on the
screen if not. Each test file has to be included in that to get
included in release archives and forgetting to add files there is a common
mistake. This is an attempt to make it harder to forget.
Daniel Stenberg (9 Jan 2010)
- Johan van Selst found and fixed a OpenSSL session ref count leak:
ossl_connect_step3() increments an SSL session handle reference counter on
each call. When sessions are re-used this reference counter may be
incremented many times, but it will be decremented only once when done (by
Curl_ossl_session_free()); and the internal OpenSSL data will not be freed
if this reference count remains positive. When a session is re-used the
reference counter should be corrected by explicitly calling
SSL_SESSION_free() after each consecutive SSL_get1_session() to avoid
introducing a memory leak.
Daniel Stenberg (7 Jan 2010)
- Make sure the progress callback is called repeatedly even during very slow
name resolves when c-ares is used for resolving.
Claes Jakobsson (6 Jan 2010)
- Julien Chaffraix fixed so that the fragment part in an URL is not sent
to the server anymore.
Kamil Dudka (3 Jan 2010)
- Julien Chaffraix eliminated a duplicated initialization in singlesocket().
Daniel Stenberg (2 Jan 2010)
- Make curl support --ssl and --ssl-reqd instead of the previous FTP-specific
versions --ftp-ssl and --ftp-ssl-reqd as these options are now used to
control SSL/TLS for IMAP, POP3 and SMTP as well in addition to FTP. The old
option names are still working but the new ones are the ones listed and
Daniel Stenberg (1 Jan 2010)
- Ingmar Runge enhanced libcurl's FTP engine to support the PRET command. This
command is a special "hack" used by the drftpd server, but even though it is
a custom extension I've deemed it fine to add to libcurl since this server
seems to survive and people keep using it and want libcurl to support
it. The new libcurl option is named CURLOPT_FTP_USE_PRET, and it is also
usable from the curl tool with --ftp-pret. Using this option on a server
that doesn't support this command will make libcurl fail.
I added test cases 1107 and 1108 to verify the functionality.
The PRET command is documented at
Yang Tse (30 Dec 2009)
- Steven M. Schweda improved VMS build system, and Craig A. Berry helped
with the patch and testing.
Daniel Stenberg (26 Dec 2009)
- Renato Botelho and Peter Pentchev brought a patch that makes the libcurl
headers work correctly even on FreeBSD systems before v8.
Daniel Stenberg (17 Dec 2009)
- David Byron fixed Curl_ossl_cleanup to actually call ENGINE_cleanup when
- Follow-up fix for the proxy fix I did for Jon Nelson's bug. It turned out I
was a bit too quick and broke test case 1101 with that change. The order of
some of the setups is sensitive. I now changed it slightly again to make
sure we do them in this order:
1 - parse URL and figure out what protocol is used in the URL
2 - prepend protocol:// to URL if missing
3 - parse name+password off URL, which needs to know what protocol is used
(since only some allows for name+password in the URL)
4 - figure out if a proxy should be used set by an option
5 - if no proxy option, check proxy environment variables
6 - run the protocol-specific setup function, which needs to have the proxy
already set
Daniel Stenberg (15 Dec 2009)
- Jon Nelson found a regression that turned out to be a flaw in how libcurl
detects and uses proxies based on the environment variables. If the proxy
was given as an explicit option it worked, but due to the setup order
mistake proxies would not be used fine for a few protocols when picked up
from '[protocol]_proxy'. Obviously this broke after 7.19.4. I now also added
test case 1106 that verifies this functionality.
Daniel Stenberg (12 Dec 2009)
- IMAP, POP3 and SMTP support and their TLS versions (including IMAPS, POP3S
and SMTPS) are now supported. The current state may not yet be solid, but
the foundation is in place and the test suite has some initial support for
these protocols. Work will now persue to make them nice libcurl citizens
until release.
The work with supporting these new protocols was sponsored by - thanks!
Daniel Stenberg (10 Dec 2009)
- Siegfried Gyuricsko found out that the curl manual said --retry would retry
on FTP errors in the transient 5xx range. Transient FTP errors are in the
4xx range. The code itself only tried on 5xx errors that occured _at login_.
Now the retry code retries on all FTP transfer failures that ended with a
4xx response.
- Constantine Sapuntzakis figured out a case which would lead to libcurl
accessing alredy freed memory and thus crash when using HTTPS (with
OpenSSL), multi interface and the CURLOPT_DEBUGFUNCTION and a certain order
of cleaning things up. I fixed it.
Daniel Stenberg (7 Dec 2009)
- Martin Storsjo made libcurl use the Expect: 100-continue header for posts
with unknown size. Previously it was only used for posts with a known size
larger than 1024 bytes.
Daniel Stenberg (1 Dec 2009)
- If the Expect: 100-continue header has been set by the application through
curl_easy_setopt with CURLOPT_HTTPHEADER, the library should set
data->state.expect100header accordingly - the current code (in 7.19.7 at
least) doesn't handle this properly. Martin Storsjo provided the fix!
Yang Tse (28 Nov 2009)
- Added Diffie-Hellman parameters to several test harness certificate files in
PEM format. Required by several stunnel versions used by our test harness.
Daniel Stenberg (28 Nov 2009)
- Markus Koetter provided a polished and updated version of Chad Monroe's TFTP
rework patch that now integrates TFTP properly into libcurl so that it can
be used non-blocking with the multi interface and more. BLKSIZE also works.
The --tftp-blksize option was added to allow setting the TFTP BLKSIZE from
the command line.
Daniel Stenberg (26 Nov 2009)
- Extended and fixed the change I did on Dec 11 for the the progress
meter/callback during FTP command/response sequences. It turned out it was
really lame before and now the progress meter SHOULD get called at least
once per second.
Daniel Stenberg (23 Nov 2009)
- Bjorn Augustsson reported a bug which made curl not report any problems even
though it failed to write a very small download to disk (done in a single
fwrite call). It turned out to be because fwrite() returned success, but
there was insufficient error-checking for the fclose() call which tricked
curl to believe things were fine.
Yang Tse (23 Nov 2009)
- David Byron modified Makefile.dist vc8 and vc9 targets in order to allow
finer granularity control when generating src and lib makefiles.
Yang Tse (22 Nov 2009)
- I modified configure to force removal of the curlbuild.h file included in
distribution tarballs for use by non-configure systems. As intended, this
would get overwriten when doing in-tree builds. But VPATH builds would end
having two curlbuild.h files, one in the source tree and another in the
build tree. With the modification I introduced 5 Nov 2009 this could become
an issue when running libcurl's test suite.
Daniel Stenberg (20 Nov 2009)
- Constantine Sapuntzakis identified a write after close, as the sockets were
closed by libcurl before the SSL lib were shutdown and they may write to its
socket. Detected to at least happen with OpenSSL builds.
- Jad Chamcham pointed out a bug with connection re-use. If a connection had
CURLOPT_HTTPPROXYTUNNEL enabled over a proxy, a subsequent request using the
same proxy with the tunnel option disabled would still wrongly re-use that
previous connection and the outcome would only be badness.
Yang Tse (18 Nov 2009)
- I modified the memory tracking system to make it intolerant with zero sized
malloc(), calloc() and realloc() function calls.
Daniel Stenberg (17 Nov 2009)
- Constantine Sapuntzakis provided another fix for the DNS cache that could
end up with entries that wouldn't time-out:
1. Set up a first web server that redirects (307) to a http://server:port
that's down
2. Have curl connect to the first web server using curl multi
After the curl_easy_cleanup call, there will be curl dns entries hanging
around with in_use != 0.
- Marc Kleine-Budde fixed: curl saved the LDFLAGS set during configure into
its pkg-config file. So -Wl stuff ended up in the .pc file, which is really
bad, and breaks if there are multiple -Wl in our LDFLAGS (which are in
PTXdist). bug #2893592 (
Kamil Dudka (15 Nov 2009)
- David Byron improved the configure script to use pkg-config to find OpenSSL
(and in particular the list of required libraries) even if a path is given
as argument to --with-ssl
Yang Tse (15 Nov 2009)
- I removed enable-thread / disable-thread configure option. These were only
placebo options. The library is always built as thread safe as possible on
every system.
Claes Jakobsson (14 Nov 2009)
- curl-config now accepts '--configure' to see what arguments was
passed to the configure script when building curl.
Daniel Stenberg (14 Nov 2009)
- Claes Jakobsson restored the configure functionality to detect NSS when
--with-nss is set but not "yes".
I think we can still improve that to check for pkg-config in that path etc,
but at least this patch brings back the same functionality we had before.
- Camille Moncelier added support for the file type SSL_FILETYPE_ENGINE for
the client certificate. It also disable the key name test as some engines
can select a private key/cert automatically (When there is only one key
and/or certificate on the hardware device used by the engine)
Yang Tse (14 Nov 2009)
- Constantine Sapuntzakis provided the fix that ensures that an SSL connection
won't be reused unless protection level for peer and host verification match.
I refactored how preprocessor symbol _THREAD_SAFE definition is done.
Kamil Dudka (12 Nov 2009)
- Kevin Baughman provided a fix preventing libcurl-NSS from crash on doubly
closed NSPR descriptor. The issue was hard to find, reported several times
before and always closed unresolved. More info at the RH bug:
- libcurl-NSS now tries to reconnect with TLS disabled in case it detects
a broken TLS server. However it does not happen if SSL version is selected
manually. The approach was originally taken from PSM. Kaspar Brand helped me
to complete the patch. Original bug reports:
Yang Tse (12 Nov 2009)
- I modified configure script to make the getaddrinfo function check also
verify if the function is thread safe.
Yang Tse (11 Nov 2009)
- Marco Maggi reported that compilation failed when configured --with-gssapi
and GNU GSS installed due to a missing mutual exclusion of header files in
the Kerberos 5 code path. He also verified that my patch worked for him.
Daniel Stenberg (11 Nov 2009)
- Constantine Sapuntzakis posted bug #2891595
( which identified how an entry
in the DNS cache would linger too long if the request that added it was in
use that long. He also provided the patch that now makes libcurl capable of
still doing a request while the DNS hash entry may get timed out.
- Christian Schmitz noticed that the progress meter/callback was not properly
used during the FTP connection phase (after the actual TCP connect), while
it of course should be. I also made the speed check get called correctly so
that really slow servers will trigger that properly too.
Kamil Dudka (5 Nov 2009)
- Dropped misleading timeouts in libcurl-NSS and made sure the SSL socket works
in non-blocking mode.
Yang Tse (5 Nov 2009)
- I removed leading 'curl' path on the 'curlbuild.h' include statement in
curl.h, adjusting auto-makefiles include path, to enhance portability to
OS's without an orthogonal directory tree structure such as OS/400.
Daniel Stenberg (4 Nov 2009)
- I fixed several problems with the transfer progress meter. It showed the
wrong percentage for small files, most notable for <1000 bytes and could
easily end up showing more than 100% at the end. It also didn't show any
percentage, transfer size or estimated transfer times when transferring
less than 100 bytes.
Version 7.19.7 (4 November 2009)
Daniel Stenberg (2 Nov 2009)
- As reported independent by both Stan van de Burgt and Didier Brisebourg,
CURLINFO_SIZE_DOWNLOAD (the -w variable size_download) didn't work when
getting data from ldap!
Daniel Stenberg (31 Oct 2009)
- Gabriel Kuri reported a problem with CURLINFO_CONTENT_LENGTH_DOWNLOAD if the
download was 0 bytes, as libcurl would then return the size as unknown (-1)
and not 0. I wrote a fix and test case 566 to verify it.
Daniel Stenberg (30 Oct 2009)
- Liza Alenchery mentioned a problem with re-used SCP connection when a bad
auth is used, as it caused a crash. I failed to repeat the issue, but still
made a change that now forces the TCP connection used for a freed SCP
session to get closed and not be re-used.
- "Tom" posted a bug report that mentioned how libcurl did wrong when doing a
POST using a read callback, with Digest authentication and
"Transfer-Encoding: chunked" enforced. I would then cause the first request
to be wrongly sent and then basically hang until the server closed the
connection. I fixed the problem and added test case 565 to verify it.
Daniel Stenberg (25 Oct 2009)
- Dima Barsky made the curl cookie parser accept cookies even with blank or
unparsable expiry dates and then treat them as session cookies - previously
libcurl would reject cookies with a date format it couldn't parse. Research
shows that the major browser treat such cookies as session cookies. I
modified test 8 and 31 to verify this.
Daniel Stenberg (21 Oct 2009)
- Attempt to use pkg-config for finding out libssh2 installation details
during configure.
- A patch in bug report #2883177 (
by Johan van Selst introduced the --crlfile option to curl, which makes curl
tell libcurl about a file with CRL (certificate revocation list) data to
Daniel Stenberg (18 Oct 2009)
- Ray Dassen provided a patch in Debian's bug tracker (bug number #551461)
that now makes curl_getdate(3) actually handles RFC 822 formatted dates that
use the "single letter military timezones". has the details.
- Fixed memory leak in the SCP/SFTP code as it never freed the knownhosts
- John Dennis filed bug report #2873666
( which identified a problem
which made libcurl loop infinitely when given incorrect credentials when
using HTTP GSS negotiate authentication. He also provided a small and simple
patch for it.
- Kevin Baughman found a double close() problem with libcurl-NSS, as when
libcurl called NSS to close the SSL "session" it also closed the actual
Yang Tse (17 Oct 2009)
- Bug report #2866724 indicated
( that curl on Windows failed
when writing files whose file names originally contained characters which
are not valid for file names on Windows. Dan Fandrich provided an initial
patch and another revised one to fix this issue.
Daniel Stenberg (1 Oct 2009)
- Tom Mueller correctly reported in bug report #2870221
( that libcurl returned an
incorrect return code from the internal trynextip() function which caused
him grief. This is a regression that was introduced in 7.19.1 and I find it
strange it hasn't hit us harder, but I won't persue into figuring out
exactly why.
- Constantine Sapuntzakis: The current implementation will always set
SO_SNDBUF to CURL_WRITE_SIZE even if the SO_SNDBUF starts out larger. The
patch doesn't do a setsockopt if SO_SNDBUF is already greater than
CURL_WRITE_SIZE. This should help folks who have set up their computer with
large send buffers.
Daniel Stenberg (27 Sep 2009)
- I introduced a maximum limit for received HTTP headers. It is controlled by
the define CURL_MAX_HTTP_HEADER which is even exposed in the public header
file to allow for users to fairly easy rebuild libcurl with a modified
limit. The rationale for a fixed limit is that libcurl is realloc()ing a
buffer to be able to put a full header into it, so that it can call the
header callback with the entire header, but that also risk getting it into
trouble if a server by mistake or willingly sends a header that is more or
less without an end. The limit is set to 100K.
Daniel Stenberg (26 Sep 2009)
- John P. McCaskey posted a bug report that showed how libcurl did wrong when
saving received cookies with no given path, if the path in the request had a
query part. That is means a question mark (?) and characters on the right
side of that. I wrote test case 1105 and fixed this problem.
Kamil Dudka (26 Sep 2009)
- Implemented a protocol independent way to specify blocking direction, used by
transfer.c for blocking. It is currently used only by SCP and SFTP protocols.
This enhancement resolves an issue with 100% CPU usage during SFTP upload,
reported by Vourhey.
Daniel Stenberg (25 Sep 2009)
- Chris Mumford filed bug report #2861587
( identifying that libcurl used
the OpenSSL function X509_load_crl_file() wrongly and failed if it would
load a CRL file with more than one certificate within. This is now fixed.
Daniel Stenberg (16 Sep 2009)
- Sven Anders reported that we introduced a cert verfication flaw for OpenSSL-
powered libcurl in 7.19.6. If there was a X509v3 Subject Alternative Name
field in the certficate it had to match and so even if non-DNS and non-IP
entry was present it caused the verification to fail.
Daniel Fandrich (15 Sep 2009)
- Moved the libssh2 checks after the SSL library checks. This helps when
statically linking since libssh2 needs the SSL library link flags to be
set up already to satisfy its dependencies. This wouldn't be necessary if
the libssh2 configure check was changed to use pkg-config since the
--static flag would add the dependencies automatically.
Yang Tse (14 Sep 2009)
- Revert Joshua Kwan's patch committed 11 Sep 2009.
Some systems poll function sets POLLHUP in revents without setting
POLLIN, and sets POLLERR without setting POLLIN and POLLOUT. In some
libcurl code execution paths this could trigger busy wait loops with
high CPU usage until a timeout condition aborted the loop.
The reverted patch addressed the above issue for a very specific case,
when awaiting c-ares to resolve. A libcurl-wide fix for Curl_poll now
superceeds this one.
Guenter Knauf (11 Sep 2009)
- Joshua Kwan provided a patch to pass POLLERR / POLLHUP back to c-ares.
This fixes a loop problem with high CPU usage.
Daniel Stenberg (10 Sep 2009)
- Claes Jakobsson fixed a problem with cookie expiry dates at exctly the epoch
start second "Thu Jan 1 00:00:00 GMT 1970" as the date parser then returns 0
which internally then is treated as a session cookie. That particular date
is now made to get the value of 1.
Daniel Stenberg (2 Sep 2009)
- Daniel Johnson found a flaw in the code converting sftp-errors to libcurl
Daniel Stenberg (1 Sep 2009)
- Peter Sylvester made a debug feature for Curl_resolv() that now will force
libcurl to resolve 'localhost' whatever name you use in the URL *if* you set
the --interface option to (exactly) "LocalHost". This will enable us to
write tests for custom hosts names but still use a local host server.
- configure now tries to use pkg-config for a number of sub-dependencies even
when cross-compiling. The key to success is then you properly setup
PKG_CONFIG_PATH before invoking configure.
I also improved how NSS is detected by trying nss-config if pkg-config isn't
present, and as a last resort just use the lib name and force the user to
setup the LIBS/LDFLAGS/CFLAGS etc properly. The previous last resort would
add a range of various libs that would almost never be quite correct.
Daniel Stenberg (31 Aug 2009)
- When using the multi interface with FTP and you asked for NOBODY, you did no
QUOTE commands and the request used the same path as the connection had
already changed to, it would decide that no commands would be necessary for
the "DO" action and that was not handled properly but libcurl would instead
Kamil Dudka (28 Aug 2009)
- Improved error message for not matching certificate subject name in
libcurl-NSS. Originally reported at:
Patrick Monnerat (24 Aug 2009)
- Introduced a SYST-based test to properly set-up name format when dealing
with the OS/400 FTP server.
- Fixed an ftp_readresp() bug preventing detection of failing control socket
and causing FTP client to loop forever.
Daniel Stenberg (24 Aug 2009)
- Marc de Bruin pointed out that configure --with-gnutls=PATH didn't work
properly and provided a fix.
- Eric Wong introduced support for the new option -T. (dot) that makes curl
read stdin in a non-blocking fashion. This also brings back -T- (minus) to
the previous blocking behavior since it could break stuff for people at
Michal Marek (21 Aug 2009)
- With CURLOPT_PROXY_TRANSFER_MODE, avoid sending invalid URLs like;type=i if the user specified without the
Daniel Stenberg (21 Aug 2009)
- Andre Guibert de Bruet pointed out a missing return code check for a
strdup() that could lead to segfault if it returned NULL. I extended his
suggest patch to now have Curl_retry_request() return a regular return code
and better check that.
- Lots of good work by Krister Johansen, mostly related to pipelining:
Fix SIGSEGV on free'd easy_conn when pipe unexpectedly breaks
Fix data corruption issue with re-connected transfers
Fix use after free if we're completed but easy_conn not NULL
Kamil Dudka (13 Aug 2009)
- Changed NSS code to not ignore the value of ssl.verifyhost and produce more
verbose error messages. Originally reported at:
Daniel Stenberg (12 Aug 2009)
- Karl Moerder fixed the* makefiles to include the new file
nonblock.c so that they work fine again
- I expanded test 517 with a bunch of more dates that originate from the
Chrome browser test suite. It turns out most of them get parsed the same
Version 7.19.6 (12 August 2009)
Daniel Stenberg (12 Aug 2009)
- Carsten Lange reported a bug and provided a patch for TFTP upload and the
sending of the TSIZE option. I don't like fixing bugs just hours before
a release, but since it was broken and the patch fixes this for him I decided
to get it in anyway.
Daniel Stenberg (11 Aug 2009)
- Peter Sylvester made the HTTPS test server use specific certificates for
each test, so that the test suite can now be used to actually test the
verification of cert names etc. This made an error show up in the OpenSSL-
specific code where it would attempt to match the CN field even if a
subjectAltName exists that doesn't match. This is now fixed and verified
in test 311.
- Benbuck Nason posted the bug report #2835196
(, fixing a few compiler
warnings when mixing ints and bools.
Daniel Fandrich (10 Aug 2009)
- Fixed a memory leak in the FTP code and an off-by-one heap buffer overflow.
Daniel Fandrich (9 Aug 2009)
- Fixed some memory leaks in the command-line tool that caused most of the
torture tests to fail.
Daniel Stenberg (2 Aug 2009)
- Curt Bogmine reported a problem with SNI enabled on a particular server. We
should introduce an option to disable SNI, but as we're in feature freeze
now I've addressed the obvious bug here (pointed out by Peter Sylvester): we
shouldn't try to enable SNI when SSLv2 or SSLv3 is explicitly selected.
Code for OpenSSL and GnuTLS was fixed. NSS doesn't seem to have a particular
option for SNI, or are we simply not using it?
Daniel Stenberg (1 Aug 2009)
- Scott Cantor posted the bug report #2829955
( mentioning the recent SSL cert
verification flaw found and exploited by Moxie Marlinspike. The presentation
he did at Black Hat is available here:
Apparently at least one CA allowed a subjectAltName or CN that contain a
zero byte, and thus clients that assumed they would never have zero bytes
were exploited to OK a certificate that didn't actually match the site. Like
if the name in the cert was "\", libcurl would
happily verify that cert for
libcurl now better uses the length of the extracted name, not using the zero
termination for getting the string length.
This fixing only made and needed in OpenSSL interfacing code.
- Tanguy Fautre pointed out that OpenSSL's function RAND_screen() (present
only in some OpenSSL installs - like on Windows) isn't thread-safe and we
agreed that moving it to the global_init() function is a decent way to deal
with this situation.
- Alexander Beedie provided the patch for a noproxy problem: If I have set
CURLOPT_NOPROXY to "*", or to a host that should not use a proxy, I actually
could still end up using a proxy if a proxy environment variable was set.
Daniel Stenberg (27 Jul 2009)
- All the quote options (CURLOPT_QUOTE, CURLOPT_POSTQUOTE and
CURLOPT_PREQUOTE) now accept a preceeding asterisk before the command to
send when using FTP, as a sign that libcurl shall simply ignore the response
from the server instead of treating it as an error. Not treating a 400+ FTP
response code as an error means that failed commands will not abort the
chain of commands, nor will they cause the connection to get disconnected.
Daniel Stenberg (26 Jul 2009)
- Johan van Selst posted bug report #2825989
( pointing out that
OpenSSL-powered libcurl didn't support the SHA-2 digest algorithm, and
provided the solution too: to use OpenSSL_add_all_algorithms() in addition
to the older SSLeay_* alternative. OpenSSL_add_all_algorithms was added in
OpenSSL 0.9.5
Daniel Stenberg (23 Jul 2009)
They introduce known_host support for SSH keys to libcurl. See docs for
details. Note that this feature depends on a new enough libssh2 version, to
be supported in libssh2 1.2 and later (or current git repo at this time).
Michal Marek (22 Jul 2009)
- David Binderman found a memory and fd leak in lib/gtls.c:load_file()
( When looking at the code, I found that
also the ptr pointer can leak.
Kamil Dudka (20 Jul 2009)
- Claes Jakobsson improved the support for client certificates handling in
NSS-powered libcurl. Now the client certificates can be selected
automatically by a NSS built-in hook. Additionally pre-login to all PKCS11
slots is no more performed. It used to cause problems with HW tokens.
- Fixed reference counting for NSS client certificates. Now the PEM reader
module should be always properly unloaded on Curl_nss_cleanup(). If the
unload fails though, libcurl will try to reuse the already loaded instance.
Daniel Fandrich (15 Jul 2009)
- Added nonblock.c to the non-automake makefiles (note that the dependencies
in the Watcom makefiles aren't quite correct).
Michal Marek (15 Jul 2009)
- Changed the description of CURLINFO_OS_ERRNO to make it clear that the
errno is not reset on success.
Guenter Knauf (14 Jul 2009)
- renamed generated config.h to curl_config.h to avoid any future clashes
with config.h from other projects.
Daniel Stenberg (9 Jul 2009)
- Eric Wong introduced curlx_nonblock() that the curl tool now (re-)uses for
setting a file descriptor non-blocking. Used by the functionality Eric
himself brough on June 15th.
Daniel Stenberg (8 Jul 2009)
- Constantine Sapuntzakis posted bug report #2813123
( and an a patch that fixes the
Url A is accessed using auth. Url A redirects to Url B (on a different
server0. Url B reuses a persistent connection. Url B has auth, even though
it's on a different server.
Note: if Url B does not reuse a persistent connection, auth is not sent.
data->state.first_host is not initialized becuase Curl_http_connect is not
called when a connection is reused.
move initialization of data->state.first_host to Curl_http. No code before
Curl_http uses data->state.first_host anyway.
Guenter Knauf (4 Jul 2009)
- Markus Koetter provided a patch to avoid getnameinfo() usage which broke a
couple of both IPv4 and IPv6 autobuilds.
Daniel Stenberg (29 Jun 2009)
- Markus Koetter made CURLOPT_FTPPORT (and curl's -P/--ftpport) support a port
range if given colon-separated after the host name/address part. Like
- Modified the separators used for CURLOPT_CERTINFO in multi-part outputs. I
don't know how they got wrong in the first place, but using this output
format makes it possible to quite easily separate the string into an array
of multiple items.
Daniel Fandrich (16 June 2009)
- Added a few more compiler warning options for gcc.
Daniel Stenberg (16 Jun 2009)
- Reuven Wachtfogel made curl -o - properly produce a binary output on windows
(no newline translations). Use -B/--use-ascii if you rather get the ascii
Michal Marek (16 Jun 2009)
- When doing non-anonymous ftp via http proxies and the password is not
provided in the url, add it there (squid needs this).
Daniel Stenberg (15 Jun 2009)
- Eric Wong's patch:
This allows curl(1) to be used as a client-side tunnel for arbitrary stream
protocols by abusing chunked transfer encoding in both the HTTP request and
HTTP response. This requires server support for sending a response while a
request is still being read, of course.
If attempting to read from stdin returns EAGAIN, then we pause our sender.
This leaves curl to attempt to read from the socket while reading from stdin
(and thus sending) is paused.
This change was needed to allow successfully tunneling the git protocol over
HTTP (--no-buffer is needed, as well).
Patrick Monnerat (15 Jun 2009)
- Replaced use of standard C library rand()/srand() by our own pseudo-random
number generator.
Yang Tse (11 Jun 2009)
- I adapted testcurl script to allow building test harness programs when
cross-compiling for a *-*-mingw* host.
Daniel Stenberg (10 Jun 2009)
- Fabian Keil ran clang on the (lib)curl code, found a bunch of warnings and
contributed a range of patches to fix them.
Yang Tse (10 Jun 2009)
- I introduced configure script option --enable-curldebug which now allows
the decoupled enabling or disabling of the curl debug memory tracking
feature from the --enable-debug option which no longer controls this.
curl --version will list 'Debug' feature for debug enabled builds, and
will list 'TrackMemory' feature for curl debug memory tracking capable
builds. These features are independent and can be controlled when running
the configure script. When --enable-debug is given both features will be
enabled, unless some restriction prevents memory tracking from being used.
Internally, definition of preprocessor symbol DEBUGBUILD restricts code
which is only compiled for debug enabled builds. And symbol CURLDEBUG is
used to differentiate code which is _only_ used for memory tracking.
Yang Tse (9 Jun 2009)
- Daniel Steinberg pointed out that Curl_FormInit() in formdata.c was not
initializing the fread callback pointer and this triggered a compiler
warning, also provided a friendly suggestion on how to fix it.
Daniel Stenberg (8 Jun 2009)
- Claes Jakobsson provided a patch for libcurl-NSS that fixed a bad refcount
issue with client certs that caused issues like segfaults.
- Triggered by bug report #2798852 and the patch in there, I fixed configure
to detect gnutls build options with pkg-config only and not libgnutls-config
anymore since GnuTLS has stopped distributing that tool. If an explicit path
is given to configure, we will instead guess on how to link and use that
lib. I did not use the patch from the bug report.
Yang Tse (8 Jun 2009)
- Igor Novoseltsev adjusted Makefile.vxworks to get sources and headers
included from, and provided docs\INSTALL VxWorks section.
- I removed buildconf.bat from release and daily snapshot archives. This
file is only for CVS tree checkout builds.
Daniel Stenberg (8 Jun 2009)
- Eric Wong fixed --no-buffer to actually switch off output buffering. Been
broken since 7.19.0
Bill Hoffman (6 Jun 2009)
- Added some cmake docs and fixed socklen_t in the build.
Yang Tse (5 Jun 2009)
- John E. Malmberg provided VMS specific patch: "This fixes an existing bug
in urlglob.c where it was not converting the Curl Unix exit code to a VMS
DCL compatible exit code. This fix required the enhancement described next.
This also adds an enhancement to main.c so that when curl is run under a
Unix shell like Bash on VMS, it will return the standard Unix exit codes
and messages." And another patch for docs/examples.
I introduced os-specific.c and os-specific.h for use in curl tool code
and adjusted John E. Malmberg's patch placement to use these new files
as an effort to prevent main.c from growing ad infinitum. Code already
existing in main.c which is OS specific should be moved into these files.
Daniel Stenberg (4 June 2009)
- Setting the Content-Length: header from your app when you do a POST or PUT
is almost always a VERY BAD IDEA. Yet there are still apps out there doing
this, and now recently it triggered a bug/side-effect in libcurl as when
libcurl sends a POST or PUT with NTLM, it sends an empty post first when it
knows it will just get a 401/407 back. If the app then replaced the
Content-Length header, it caused the server to wait for input that libcurl
wouldn't send. Aaron Oneal reported this problem in bug report #2799008
( and helped us verify the fix.
Yang Tse (4 Jun 2009)
- Igor Novoseltsev provided patches and information, that after some
adjustments to better fit curl's way of doing things, have resulted
in the posibility of building libcurl for VxWorks.
Daniel Fandrich (2 June 2009)
- Checked in a Google Android make file. To use it, you must first
create a config.h file by running configure in the Android environment,
which doesn't seem to be easy to do. If no easy way can be found, a
static config-android.h may need to be created and checked in to the
libcurl source tree.
Daniel Stenberg (1 June 2009)
- Claes Jakobsson fixed the configure script to better find and use NSS
without pkg-config.
Yang Tse (1 Jun 2009)
- John E. Malmberg provided a VMS specific clean-up for curl.h, and pointed
out that the configure script was failing to detect the timeval struct on
VMS when building with _XOPEN_SOURCE_EXTENDED undefined due to definition
taking place in socket.h instead of time.h. I have adjusted configure
script to also include this header when checking struct timeval.
Daniel Stenberg (27 May 2009)
- Frank McGeough provided a small OpenSSL #include fix to make libcurl compile
fine with Nokia 5th edition 1.0 SDK for Symbian.
- Andre Guibert de Bruet found a call to a OpenSSL function that didn't check
for a failure properly.
- Mike Crowe pointed out that setting CURLOPT_USERPWD to NULL used to clear
the auth credentials back in 7.19.0 and earlier while now you have to set ""
to get the same effect. His patch brings back the ability to use NULL.
- Claes Jakobsson fixed libcurl-NSS to build fine even without the
PK11_CreateGenericObject() function.
Daniel Stenberg (25 May 2009)
- bug report #2796358 ( pointed
out that the cookie parser would leak memory when it parses cookies that are
received with domain, path etc set multiple times in the same header. While
such a cookie is questionable, they occur in the wild and libcurl no longer
leaks memory for them. I added such a header to test case 8.
Daniel Fandrich (22 May 2009)
- Removed some obsolete digest code that caused a valgrind error in test 551.
Daniel Fandrich (20 May 2009)
- Added "non-existing host" test keywords to make it easy to skip those
tests on machines that have broken DNS configurations (such as
those configured to use OpenDNS).
Daniel Stenberg (19 May 2009)
- Kamil Dudka brought the patch from the Redhat bug entry which was libcurl closing
a bad file descriptor when closing down the FTP data connection. Caolan
McNamara seems to be the original author of it.
Version 7.19.5 (18 May 2009)
Daniel Stenberg (17 May 2009)
- James Bursa posted a patch to the mailing list that fixed a problem with
no_proxy which made it not skip the proxy if the URL entered contained a
user name. I added test case 1101 to verify.
Daniel Stenberg (11 May 2009)
- Balint Szilakszi reported a memory leak when libcurl did gzip decompression
of streams that had some parts (legitimately) missing. We now provide and use
a proper cleanup function for the content encoding submodule.
- Kamil Dudka provided a fix for libcurl-NSS reported by Michael Cronenworth
If an incorrect password is given while loading a private key, libcurl ends
up in an infinite loop consuming memory. The bug is critical.
- I fixed the problem with doing NTLM, POST and then following a 302 redirect,
as reported by Ebenezer Ikonne (on curl-users) and Laurent Rabret (on
curl-library). The transfer was mistakenly marked to get more data to send
but since it didn't actually have that, it just hung there...
Daniel Stenberg (10 May 2009)
- Andre Guibert de Bruet correctly pointed out an over-alloc with one wasted
byte in the digest code.
Yang Tse (9 May 2009)
- Removed DOS and TPF package's subdirectory, it was only used
to include some files in the distribution tarball serving no other purpose.
Files from the DOS and TPF subdirectories are now included in the EXTRA_DIST
of the Makefile in the parent subdirectory.
Yang Tse (8 May 2009)
- Changed host name literal in several tests to one under the domain.
- Renamed vc6 workspace and project files to avoid filename clash when used
for conversion to later VS versions.
Daniel Stenberg (8 May 2009)
- Constantine Sapuntzakis fixed bug report #2784055
( identifying a problem to
connect to SOCKS proxies when using the multi interface. It turned out to
almost not work at all previously. We need to wait for the TCP connect to
be properly verified before doing the SOCKS magic.
There's still a flaw in the FTP code for this.
Daniel Stenberg (7 May 2009)
- Made the SO_SNDBUF setting for the data connection socket for ftp uploads as
well. See change 28 Apr 2009.
Yang Tse (7 May 2009)
- Fixed an issue affecting FTP transfers, introduced with the transfer.c
patch committed May 4.
Daniel Stenberg (7 May 2009)
- Man page *roff problems fixed thanks to input from Colin Watson. Problems
reported in the Debian package.
- Vijay G filed bug report #2723236
( identifying a problem with
libcurl's TFTP code and its lack of dealing with the OACK packet.
Yang Tse (5 May 2009)
- Fixed the --ftp-port address of test #251 to the CLIENTIP address, and
reverted the change affecting test suite harness committed 4 May.
Daniel Stenberg (5 May 2009)
- Inspired by Michael Smith's session id fix for OpenSSL, I did the
corresponding fix in the GnuTLS code: make sure to store the new session id
in case the previous re-used one is rejected.
Daniel Stenberg (4 May 2009)
- Michael Smith posted bug report #2786255
( with a patch, identifying how
libcurl did not deal with SSL session ids properly if the server rejected a
re-use of one. Starting now, it will forget the rejected one and remember
the new. This change was for OpenSSL only, it is likely that other SSL lib
code needs similar fixes.
Yang Tse (4 May 2009)
- Applied David McCreedy's "transfer.c fixes for CURL_DO_LINEEND_CONV and
non-ASCII platform HTTP requests" patch addressing two HTTP PUT problems:
1) On non-ASCII platforms not all of the protocol portions of the PUT are
being translated to ASCII. 2) On all platforms the line endings of part of
the protocol portions are mangled from CRLF to CRCRLF if data->set.crlf or
data->set.prefer_ascii are set (depending on CURL_DO_LINEEND_CONV).
- Applied David McCreedy's patch to fix test suite harness to allow test FTP
server and client on different machines, providing FTP client address when
running the FTP test server.
Daniel Fandrich (3 May 2009)
- Added and disabled test case 563 which shows KNOWN_BUGS #59. The bug
report failed to mention that a proxy must be used to reproduce it.
Yang Tse (2 May 2009)
- Use a build-time configured curl_socklen_t data type instead of socklen_t.
Yang Tse (1 May 2009)
- Applied David McCreedy's patches "TPF-platform specific changes to various
files" and "http.c fix to Curl_proxyCONNECT for non-ASCII platforms", the
former with minor edits.
Daniel Stenberg (30 Apr 2009)
- I was going to fix issue #59 in KNOWN_BUGS
If the CURLOPT_PORT option is used on an FTP URL like
";type=A" the ";type=A" is stripped off.
I added test case 562 to verify, only to find out that I couldn't repeat
this bug so I hereby consider it not a bug anymore!
Daniel Stenberg (29 Apr 2009)
- Based on bug report #2723219 (
I've now made TFTP "connections" not being kept for re-use within libcurl.
TFTP is UDP-based so the benefit was really low (if even existing) to begin
with so instead of tracking down to fix this problem we instead removed the
re-use. I also enabled test case 1099 that I wrote a few days ago to verify
that this change fixes the reported problem.
Daniel Stenberg (28 Apr 2009)
- Constantine Sapuntzakis filed bug report #2783090
( pointing out that on windows
we need to grow the SO_SNDBUF buffer somewhat to get really good upload
speeds. has the details. Friends
confirmed that simply adding 32 to CURL_MAX_WRITE_SIZE is enough.
- Bug report #2709004 ( by Tim
Chen pointed out how curl couldn't upload with resume when reading from a
This ended up with the introduction of a new return code for the
CURLOPT_SEEKFUNCTION callback that basically says that the seek failed but
that libcurl may try to resolve the situation anyway. In our case this means
libcurl will attempt to instead read that much data from the stream instead
of seeking and that way curl can now upload with resume when data is read
from a stream!
Daniel Stenberg (26 Apr 2009)
- Bug report #2779733 ( by Sven
Wegener pointed out that CURLINFO_APPCONNECT_TIME didn't work with the multi
interface and provided a patch that fixed the problem!
Daniel Stenberg (24 Apr 2009)
- Kamil Dudka fixed another NSS-related leak when client certs were used.
- Bug report #2779245 ( by Rainer
Koenig pointed out that the man page didn't tell that the *_proxy
environment variables can be specified lower case or UPPER CASE and the
lower case takes precedence,
Daniel Fandrich (21 Apr 2009)
- Added new libcurl source files to Amiga, RiscOS and VC6 build files.
Yang Tse (21 Apr 2009)
- Moved potential inclusion of system's malloc.h and memory.h header files to
setup_once.h. Inclusion of each header file is based on the definition of
NEED_MALLOC_H and NEED_MEMORY_H respectively.
Renamed libcurl's memory.h to curl_memory.h
Daniel Stenberg (20 Apr 2009)
- Leanic Lefever reported a crash and did some detailed research on why and
how it occurs ( The
conclusion was that if an error is detected and Curl_done() is called for
the connection, ftp_done() could at times return another error code that
then would take precedence and that new code confused existing logic that
works for the first error code (CURLE_SEND_ERROR) only.
- Gisle Vanem noticed that --libtool would produce bogus strings at times for
OBJECTPOINT options. Now we've introduced a new function - my_setopt_str -
within the app for setting plain string options to avoid the risk of this
mistake happening.
Daniel Stenberg (17 Apr 2009)
- Pramod Sharma reported and tracked down a bug when doing FTP over a HTTP
proxy. libcurl would then wrongly close the connection after each
request. In his case it had the weird side-effect that it killed NTLM auth
for the proxy causing an inifinite loop!
I added test case 1098 to verify this fix. The test case does however not
properly verify that the transfers are done persistently - as I couldn't
think of a clever way to achieve it right now - but you need to read the
stderr output after a test run to see that it truly did the right thing.
Daniel Stenberg (13 Apr 2009)
- bug report #2727981 ( by Martin
Storsjö pointed out how setting CURLOPT_NOBODY to 0 could be downright
confusing as it set the method to either GET or HEAD. The example he showed
looked like:
curl_easy_setopt(curl, CURLOPT_PUT, 1);
curl_easy_setopt(curl, CURLOPT_NOBODY, 0);
The new way doesn't alter the method until the request is about to start. If
CURLOPT_NOBODY is then 1 the HTTP request will be HEAD. If CURLOPT_NOBODY is
0 and the request happens to have been set to HEAD, it will then instead be
set to GET. I believe this will be less surprising to users, and hopefully
not hit any existing users badly.
- Toshio Kuratomi reported a memory leak problem with libcurl+NSS that turned
out to be leaking cacerts. Kamil Dudka helped me complete the fix. The issue
is found in Redhat's bug tracker:
There are still memory leaks present, but they seem to have other reasons.
Daniel Fandrich (11 Apr 2009)
- Added new libcurl source files to Symbian OS build files.
- Improved Symbian support for SSL.
Yang Tse (10 Apr 2009)
- Daniel Johnson improved the MacOSX-Framework shell script to now perform all
the steps required to build a Mac OS X four way fat ppc/i386/ppc64/x86_64
libcurl.framework. Four way fat framework requires OS X 10.5 SDK or later.
Yang Tse (8 Apr 2009)
- Removed Sun compilers preprocessor block from curlbuild.h.dist, this also
removes it from the curlbuild.h file originally distributed by the cURL
project as this file is intended for systems not capable of running the
configure script. For those who have been building curl out of the source
code curl distribution tarball provided by the change implies
nothing. Previous change in this area committed 2 Apr becomes irrelevant.
Daniel Stenberg (6 Apr 2009)
- I clarified in the docs that CURLOPT_SEEKFUNCTION should return 0 on success
and 1 on fatal errors. Previously it only mentioned non-zero on fatal
errors. This is a slight change in meaning, but it follows what we've done
elsewhere before and it opens up for LOTS of more useful return codes
whenever we can think of them...
Yang Tse (2 Apr 2009)
- Fix curl_off_t definition for builds done using Sun compilers and a
non-configured libcurl. In this case curl_off_t data type was gated
to the off_t data type which depends on the _FILE_OFFSET_BITS. This
configuration is exactly the unwanted configuration for our curl_off_t
data type which must not depend on such setting. This breaks ABI for
libcurl libraries built with Sun compilers which were built without
having run the configure script with _FILE_OFFSET_BITS different than
64 and using the ILP32 data model.
Daniel Stenberg (1 Apr 2009)
- Andre Guibert de Bruet fixed a NULL pointer use in an infof() call if a
strdup() call failed.
Daniel Fandrich (31 Mar 2009)
- Properly return an error code in curl_easy_recv (reported by Jim Freeman).
Daniel Stenberg (18 Mar 2009)
- Kamil Dudka brought a patch that enables 6 additional crypto algorithms when
NSS is used. These ciphers were added in NSS 3.4 and require to be enabled
Daniel Stenberg (13 Mar 2009)
- Use libssh2_version() to present the libssh2 version in case the libssh2
library is found to support it.
Yang Tse (12 Mar 2009)
- Added missing Curl_read() return code checking in TELNET transfers.
- Pierre Brico found and fixed TELNET transfers not being aborted upon
a write callback failure.
Daniel Stenberg (11 Mar 2009)
- Kamil Dudka made the curl tool properly call curl_global_init() before any
other libcurl function.
Yang Tse (11 Mar 2009)
- Added missing TELNET timeout support for Windows builds. This issue was
reported by Pierre Brico.
Daniel Stenberg (9 Mar 2009)
- Frank Hempel found out a bug and provided the fix:
curl_easy_duphandle did not necessarily duplicate the CURLOPT_COOKIEFILE
option. It only enabled the cookie engine in the destination handle if
data->cookies is not NULL (where data is the source handle). In case of a
newly initialized handle which just had the cookie support enabled by a
curl_easy_setopt(handle, CURL_COOKIEFILE, "")-call, handle->cookies was
still NULL because the setopt-call only appends the value to
data->change.cookielist, hence duplicating this handle would not have the
cookie engine switched on.
We also concluded that the slist-functionality would be suitable for being
put in its own module rather than simply hanging out in lib/sendf.c so I
created lib/slist.[ch] for them.
- Andreas Farber made the 'buildconf' script check for the presence of m4
scripts to make it detect a bad checkout earlier. People with older
checkouts who don't do cvs update with the -d option won't get the new dirs
and then will get funny outputs that can be a bit hard to understand and
Daniel Stenberg (8 Mar 2009)
- Andre Guibert de Bruet found and fixed a code segment in ssluse.c where the
allocation of the memory BIO was not being properly checked.
- Andre Guibert de Bruet fixed the gnutls-using code: There are a few places
in the gnutls code where we were checking for negative values for errors,
when the man pages state that GNUTLS_E_SUCCESS is returned on success and
other values indicate error conditions.
- Bill Egert pointed out ( that
curl didn't use sprintf() in a way that is documented to work in POSIX but
since we use our own printf() code (from libcurl) that shouldn't be a
problem. Nonetheless I modified the code to not rely on such particular
features and to not cause further raised eyebrowse with no good reason.
Daniel Fandrich (5 Mar 2009)
- Expanded the security section of the libcurl-tutorial man page to cover
more issues for authors to consider when writing robust libcurl-using
Yang Tse (5 Mar 2009)
- Fixed NTLM authentication memory leak on SSPI enabled Windows builds. This
issue was noticed by Chris Deidun.
Daniel Fandrich (4 Mar 2009)
- Fixed a problem with m4 quoting in the OpenSSL configure check reported
by Daniel Johnson.
Daniel Stenberg (3 Mar 2009)
- David James brought a patch that make libcurl close (all) dead connections
whenever you attempt to open a new connection.
1. After cleaning up a dead connection, "continue" instead of
returning FALSE. This ensures that we clean up all dead connections,
rather than just cleaning up the first dead connection.
2. Move up the cleanup for dead connections so that it occurs for
all connections, rather than just the connections which have the same
preferences as our current new connection.
Version 7.19.4 (3 March 2009)
Daniel Stenberg (3 Mar 2009)
- David Kierznowski notified us about a security flaw
( also known as CVE-2009-0037) in
which previous libcurl versions (by design) can be tricked to access an
arbitrary local/different file instead of a remote one when
CURLOPT_FOLLOWLOCATION is enabled. This flaw is now fixed in this release
together this the addition of two new setopt options for controlling this
new behavior:
o CURLOPT_REDIR_PROTOCOLS controls what protocols libcurl is allowed to
follow to when CURLOPT_FOLLOWLOCATION is enabled. By default, this option
excludes the FILE and SCP protocols and thus you nee to explicitly allow
them in your app if you really want that behavior.
o CURLOPT_PROTOCOLS controls what protocol(s) libcurl is allowed to fetch
using the primary URL option. This is useful if you want to allow a user or
other outsiders control what URL to pass to libcurl and yet not allow all
protocols libcurl may have been built to support.
Daniel Stenberg (27 Feb 2009)
- Senthil Raja Velu reported a problem when CURLOPT_INTERFACE and
CURLOPT_LOCALPORT were used together (the local port bind failed), and
Markus Koetter provided the fix!
Daniel Stenberg (25 Feb 2009)
- As Daniel Fandrich figured out, we must do the GnuTLS initing in the
curl_global_init() function to properly maintain the performing functions
thread-safe. We've previously (28 April 2007) moved the init to a later time
just to avoid it to fail very early when libgcrypt dislikes the situation,
but that move was bad and the fix should rather be in libgcrypt or
Daniel Stenberg (24 Feb 2009)
- Brian J. Murrell found out that Negotiate proxy authentication didn't work.
It happened because the code used the struct for server-based auth all the
time for both proxy and server auth which of course was wrong.
Daniel Stenberg (23 Feb 2009)
- After a bug reported by James Cheng I've made curl_easy_getinfo() for
-1 if the sizes aren't know. Previously these returned 0, make it impossible
to detect the difference between actually zero and unknown.
Yang Tse (23 Feb 2009)
- Daniel Johnson provided a shell script that will perform all the steps needed
to build a Mac OS X fat ppc/i386 or ppc64/x86_64 libcurl.framework
Daniel Stenberg (23 Feb 2009)
- I renamed everything in the windows builds files that used the name 'curllib'
to the proper 'libcurl' as clearly this caused confusion.
Yang Tse (20 Feb 2009)
- Do not halt compilation when using VS2008 to build a Windows 2000 target.
Daniel Stenberg (20 Feb 2009)
- Linus Nielsen Feltzing reported and helped me repeat and fix a problem with
FTP with the multi interface: when a transfer fails, like when aborted by a
write callback, the control connection was wrongly closed and thus not
re-used properly.
This change is also an attempt to cleanup the code somewhat in this area, as
now the FTP code attempts to keep (better) track on pending responses
necessary to get read in ftp_done().
Daniel Stenberg (19 Feb 2009)
- Patrik Thunstrom reported a problem and helped me repeat it. It turned out
libcurl did a superfluous 1000ms wait when doing SFTP downloads!
We read data with libssh2 while doing the "DO" operation for SFTP and then
when we were about to start getting data for the actual file part, the
"TRANSFER" part, we waited for socket action (in 1000ms) before doing a
libssh2-read. But in this case libssh2 had already read and buffered the
data so we ended up always just waiting 1000ms before we get working on the
Patrick Monnerat (18 Feb 2009)
- FTP downloads (i.e.: RETR) ending with code 550 now return error
Daniel Stenberg (17 Feb 2009)
- Kamil Dudka made NSS-powered builds compile and run again!
- A second follow-up change by Andre Guibert de Bruet to fix a related memory
leak like that fixed on the 14th. When zlib returns failure, we need to
cleanup properly before returning error.
- CURLOPT_FTP_CREATE_MISSING_DIRS can now be set to 2 in addition to 1 for
plain FTP connections, and it will then allow MKD to fail once and retry the
CWD afterwards. This is especially useful if you're doing many simultanoes
connections against the same server and they all have this option enabled,
as then CWD may first fail but then another connection does MKD before this
connection and thus MKD fails but trying CWD works! The numbers can
(should?) now be set with the convenience enums now called
Tests has proven that if you're making an application that uploads a set of
files to an ftp server, you will get a noticable gain in speed if you're
using multiple connections and this option will be then be very useful.
Daniel Stenberg (14 Feb 2009)
- Andre Guibert de Bruet found and fixed a memory leak in the content encoding
code, which could happen on libz errors.
Daniel Fandrich (12 Feb 2009)
- Added support for Digest and NTLM authentication using GnuTLS.
Daniel Stenberg (11 Feb 2009)
- CURLINFO_CONDITION_UNMET was added to allow an application to get to know if
the condition in the previous request was unmet. This is typically a time
condition set with CURLOPT_TIMECONDITION and was previously not possible to
reliably figure out. From bug report #2565128
( filed by Jocelyn Jaubert.
Daniel Fandrich (4 Feb 2009)
- Don't add the standard /usr/lib or /usr/include paths to LDFLAGS and CPPFLAGS
(respectively) when --with-ssl=/usr is used (patch based on FreeBSD).
- Added an explicit buffer limit check in msdosify() (patch based on FreeBSD).
This couldn't ever overflow in curl, but might if the code were used
elsewhere or under different conditions.
Daniel Stenberg (3 Feb 2009)
- Hidemoto Nakada provided a small fix that makes it possible to get the
CURLINFO_CONTENT_LENGTH_DOWNLOAD size from file:// "transfers" with
Daniel Stenberg (2 Feb 2009)
- Patrick Scott found a rather large memory leak when using the multi
interface and setting CURLMOPT_MAXCONNECTS to something less than the number
of handles you add to the multi handle. All the connections that didn't fit
in the cache would not be properly disconnected nor freed!
- Craig A West brought us: libcurl now defaults to do CONNECT with HTTP
version 1.1 instead of 1.0 like before. This change also introduces the new
proxy type for libcurl called 'CURLPROXY_HTTP_1_0' that then allows apps to
switch (back) to CONNECT 1.0 requests. The curl tool also got a --proxy1.0
option that works exactly like --proxy but sets CURLPROXY_HTTP_1_0.
I updated all test cases cases that use CONNECT and I tried to do some using
--proxy1.0 and some updated to do CONNECT 1.1 to get both versions run.
Daniel Stenberg (31 Jan 2009)
- When building with c-ares 1.6.1 (not yet released) or later and IPv6 support
enabled, we can now take advantage of its brand new AF_UNSPEC support in
ares_gethostbyname(). This makes test case 241 finally run fine for me with
this setup since it now parses the "::1 ip6-localhost" line fine in my
/etc/hosts file!
Daniel Stenberg (30 Jan 2009)
- Scott Cantor filed bug report #2550061
( mentioning that I failed to
properly make sure that the VC9 makefiles got included in the latest
release. I've now fixed the release script and verified it so next release
will hopefully include them properly!
Daniel Fandrich (30 Jan 2009)
- Fixed --disable-proxy for FTP and SOCKS. Thanks to Daniel Egger for
Yang Tse (29 Jan 2009)
- Introduced curl_sspi.c and curl_sspi.h for the implementation of functions
Curl_sspi_global_init() and Curl_sspi_global_cleanup() which previously were
named Curl_ntlm_global_init() and Curl_ntlm_global_cleanup() in http_ntlm.c
Also adjusted socks_sspi.c to remove the link-time dependency on the Windows
SSPI library using it now in the same way as it was done in http_ntlm.c.
Daniel Stenberg (28 Jan 2009)
- Markus Moeller introduced two new options to libcurl:
to do GSS-style authentication with SOCKS5 proxies. The curl tool got the
options called --socks5-gssapi-service and --socks5-gssapi-nec to enable
Daniel Stenberg (26 Jan 2009)
- Chad Monroe provided the new CURLOPT_TFTP_BLKSIZE option that allows an app
to set desired block size to use for TFTP transfers instead of the default
512 bytes.
- The "-no_ticket" option was introduced in Openssl0.9.8j. It's a flag to
disable "rfc4507bis session ticket support". rfc4507bis was later turned
into the proper RFC5077 it seems:
The enabled extension concerns the session management. I wonder how often
libcurl stops a connection and then resumes a TLS session. also, sending the
session data is some overhead. .I suggest that you just use your proposed
patch (which explicitly disables TICKET).
If someone writes an application with libcurl and openssl who wants to
enable the feature, one can do this in the SSL callback.
Sharad Gupta brought this to my attention. Peter Sylvester helped me decide
on the proper action.
- Alexey Borzov filed bug report #2535504
( pointing out that realms with
quoted quotation marks in HTTP Digest headers didn't work. I've now added
test case 1095 that verifies my fix.
- Craig A West brought CURLOPT_NOPROXY and the corresponding --noproxy option.
They basically offer the same thing the NO_PROXY environment variable only
offered previously: list a set of host names that shall not use the proxy
even if one is specified.
Daniel Fandrich (20 Jan 2009)
- Call setlocale() for libtest tests to test the effects of locale-induced
libc changes on libcurl.
- Fixed a couple more locale-dependent toupper conversions, mainly for
clarity. This does fix one problem that causes ;type=i FTP URLs
to fail in the Turkish locale when CURLOPT_PROXY_TRANSFER_MODE is
used (test case 561)
- Added tests 561 and 1091 through 1094 to test various combinations
of ;type= and ;mode= URLs that could potentially fail in the Turkish
Daniel Stenberg (20 Jan 2009)
- Lisa Xu pointed out that the ssh.obj file was missing from the
lib/Makefile.vc6 file (and thus from the vc8 and vc9 ones too).
Version 7.19.3 (19 January 2009)
Daniel Stenberg (16 Jan 2009)
- Andrew de los Reyes fixed curlbuild.h for "generic" gcc builds on PPC, both
32 bit and 64 bit.
Daniel Stenberg (15 Jan 2009)
- Tim Ansell fixed a compiler warning in lib/cookie.c
Daniel Stenberg (14 Jan 2009)
- Grant Erickson fixed timeouts for TFTP such that specifying a
connect-timeout, a max-time or both options work correctly and as expected
by passing the correct boolean value to Curl_timeleft via the
'duringconnect' parameter.
With this small change, curl TFTP now behaves as expected (and likely as
1) For non-existent or unreachable dotted IP addresses:
a) With no options, follows the default curl 300s timeout...
b) With --connect-timeout only, follows that value...
c) With --max-time only, follows that value...
d) With both --connect-timeout and --max-time, follows the smaller value...
and times out with a "curl: (7) Couldn't connect to server" error.
2) For transfers to/from a valid host:
a) With no options, follows default curl 300s timeout for the
first XRQ/DATA/ACK transaction and the default TFTP 3600s
timeout for the remainder of the transfer...
b) With --connect-time only, follows that value for the
first XRQ/DATA/ACK transaction and the default TFTP 3600s
timeout for the remainder of the transfer...
c) With --max-time only, follows that value for the first
XRQ/DATA/ACK transaction and for the remainder of the
d) With both --connect-timeout and --max-time, follows the former
for the first XRQ/DATA/ACK transaction and the latter for the
remainder of the transfer...
and times out with a "curl: (28) Timeout was reached" error as
Daniel Stenberg (13 Jan 2009)
- Michael Wallner fixed a NULL pointer deref when calling
curl_easy_setup(curl, CURLOPT_COOKIELIST, "SESS") on a CURL handle with no
cookies data.
- Stefan Teleman brought a patch to fix the default curlbuild.h file for the
SunPro compilers.
Daniel Stenberg (12 Jan 2009)
- Based on bug report #2498665 (
by Daniel Black, I've now added magic to the configure script that makes it
use pkg-config to detect gnutls details as well if the existing method
(using libgnutls-config) fails. While doing this, I cleaned up and unified
the pkg-config usage when detecting openssl and nss as well.
Daniel Stenberg (11 Jan 2009)
- Karl Moerder brought the patch that creates vc9 Makefiles, and I made
'maketgz' now use the actual makefile targets to do the VC8 and VC9
Daniel Stenberg (10 Jan 2009)
- Emil Romanus fixed:
When using the multi interface over HTTP and the server returns a Location
header, the running easy handle will get stuck in the CURLM_STATE_PERFORM
state, leaving the external event loop stuck waiting for data from the
ingoing socket (when using the curl_multi_socket_action stuff). While this
bug was pretty hard to find, it seems to require only a one-line fix. The
break statement on line 1374 in multi.c caused the function to skip the call
to multistate().
How to reproduce this bug? Well, that's another question. evhiperfifo.c in
the examples directory chokes on this bug only _sometimes_, probably
depending on how fast the URLs are added. One way of testing the bug out is
writing to hiper.fifo from more than one source at the same time.
Daniel Fandrich (7 Jan 2009)
- Unified much of the SessionHandle initialization done in Curl_open() and
curl_easy_reset() by creating Curl_init_userdefined(). This had the side
effect of fixing curl_easy_reset() so it now also resets
Daniel Stenberg (7 Jan 2009)
- Rob Crittenden did once again provide an NSS update:
I have to jump through a few hoops now with the NSS library initialization
since another part of an application may have already initialized NSS by the
time Curl gets invoked. This patch is more careful to only shutdown the NSS
library if Curl did the initialization.
It also adds in a bit of code to set the default ciphers if the app that
call NSS_Init* did not call NSS_SetDomesticPolicy() or set specific
ciphers. One might argue that this lets other application developers get
lazy and/or they aren't using the NSS API correctly, and you'd be right.
But still, this will avoid terribly difficult-to-trace crashes and is
generally helpful.
Daniel Stenberg (1 Jan 2009)
- 'reconf' is removed since we rather have users use 'buildconf'
Daniel Stenberg (31 Dec 2008)
- Bas Mevissen reported pointing
out that 'reconf' didn't properly point out the m4 subdirectory when running
Daniel Stenberg (29 Dec 2008)
- Phil Lisiecki filed bug report #2413067
( that identified a problem that
would cause libcurl to mark a DNS cache entry "in use" eternally if the
subsequence TCP connect failed. It would thus never get pruned and refreshed
as it should've been.
Phil provided his own patch to this problem that while it seemed to work
wasn't complete and thus I wrote my own fix to the problem.
Daniel Stenberg (28 Dec 2008)
- Peter Korsgaard fixed building libcurl with "configure --with-ssl
- Anthony Bryan fixed more language and spelling flaws in man pages.
Daniel Stenberg (22 Dec 2008)
- Given a recent enough libssh2, libcurl can now seek/resume with SFTP even
on file indexes beyond 2 or 4GB.
- Anthony Bryan provided a set of patches that cleaned up manual language,
corrected spellings and more.
Daniel Stenberg (20 Dec 2008)
- Igor Novoseltsev fixed a bad situation for the multi_socket() API when doing
pipelining, as libcurl could then easily get confused and A) work on the
handle that was not "first in queue" on a pipeline, or even B) tell the app
to REMOVE a socket while it was in use by a second handle in a pipeline. Both
errors caused hanging or stalling applications.
Daniel Stenberg (19 Dec 2008)
- curl_multi_timeout() could return a timeout value of 0 even though nothing
was actually ready to get done, as the internal time resolution is higher
than the returned millisecond timer. Therefore it could cause applications
running on fast processors to do short bursts of busy-loops.
curl_multi_timeout() will now only return 0 if the timeout is actually
alreay triggered.
- Using the libssh2 0.19 function libssh2_session_block_directions(), libcurl
now has an improved ability to do right when the multi interface (both
"regular" and multi_socket) is used for SCP and SFTP transfers. This should
result in (much) less busy-loop situations and thus less CPU usage with no
speed loss.
Daniel Stenberg (17 Dec 2008)
- SCP and SFTP with the multi interface had the same flaw: the 'DONE'
operation didn't complete properly if the EAGAIN equivalent was returned but
libcurl would simply continue with a half-completed close operation
performed. This ruined persistent connection re-use and cause some
SSH-protocol errors in general. The correction is unfortunately adding a
blocking function - doing it entirely non-blocking should be considered for
a better fix.
Gisle Vanem (16 Dec 2008)
- Added the possibility to use the Watt-32 tcp/ip stack under Windows.
The change simply involved adding a USE_WATT32 section in the
config-win32.h files (under ./lib and ./src). This section disables
the use of any Winsock headers.
Daniel Stenberg (16 Dec 2008)
- libssh2_sftp_last_error() was wrongly used at some places in libcurl which
made libcurl sometimes not properly abort problematic SFTP transfers.
Daniel Stenberg (12 Dec 2008)
- More work with Igor Novoseltsev to first fix the remaining stuff for
removing easy handles from multi handles when the easy handle is/was within
a HTTP pipeline. His bug report #2351653
( was also related and was
eventually fixed by a patch by Igor himself.
Yang Tse (12 Dec 2008)
- Patrick Monnerat fixed a build regression, introduced in 7.19.2, affecting
OS/400 compilations with IPv6 enabled.
Daniel Stenberg (12 Dec 2008)
- Mark Karpeles filed bug report #2416182 titled "crash in ConnectionExists
when using duphandle+curl_mutli"
( which showed that
curl_easy_duphandle() wrongly also copied the pointer to the connection
cache, which was plain wrong and caused a segfault if the handle would be
used in a different multi handle than the handle it was duplicated from.
Daniel Stenberg (11 Dec 2008)
- Keshav Krity found out that libcurl failed to deal with dotted IPv6
addresses if they were very long (>39 letters) due to a too strict address
validity parser. It now accepts addresses up to 45 bytes long.
Daniel Stenberg (11 Dec 2008)
- Internet Explorer had a broken HTTP digest authentication before v7 and
there are servers "out there" that relies on the client doing this broken
Digest authentication. Apache even comes with an option to work with such
broken clients.
The difference is only for URLs that contain a query-part (a '?'-letter and
text to the right of it).
libcurl now supports this quirk, and you enable it by setting the
CURLAUTH_DIGEST_IE bit in the bitmask you pass to the CURLOPT_HTTPAUTH or
CURLOPT_PROXYAUTH options. They are thus individually controlled to server
and proxy.
(note that there's no way to activate this with the curl tool yet)
Daniel Fandrich (9 Dec 2008)
- Added test cases 1089 and 1090 to test --write-out after a redirect to
test a report that the size didn't work, but these test cases pass.
- Documented CURLOPT_CONNECT_ONLY as being useful only on HTTP URLs.
Daniel Stenberg (9 Dec 2008)
- Ken Hirsch simplified how libcurl does FTPS: now it doesn't assume any
particular state for the control connection like it did before for implicit
FTPS (libcurl assumed such control connections to be encrypted while some
FTPS servers such as FileZilla assumes such connections to be clear
mode). Use the CURLOPT_USE_SSL option to set your desired level.
Daniel Stenberg (8 Dec 2008)
- Fred Machado posted about a weird FTP problem on the curl-users list and when
researching it, it turned out he got a 550 response back from a SIZE command
and then I fell over the text in RFC3659 that says:
The presence of the 550 error response to a SIZE command MUST NOT be taken
by the client as an indication that the file cannot be transferred in the
current MODE and TYPE.
In other words: the change I did on September 30th 2008 and that has been
included in the last two releases were a regression and a bad idea. We MUST
NOT take a 550 response from SIZE as a hint that the file doesn't exist.
- Christian Krause filed bug #2221237
( that identified an infinite
loop during GSS authentication given some specific conditions. With his
patience and great feedback I managed to narrow down the problem and
eventually fix it although I can't test any of this myself!
Daniel Fandrich (3 Dec 2008)
- Fixed the getifaddrs version of Curl_if2ip to work on systems without IPv6
support (e.g. Minix)
Daniel Stenberg (3 Dec 2008)
- Igor Novoseltsev filed bug #2351645
( that identified a problem with
the multi interface that occured if you removed an easy handle while in
progress and the handle was used in a HTTP pipeline.
- Pawel Kierski pointed out a mistake in the cookie code that could lead to a
bad fclose() after a fatal error had occured.
Daniel Fandrich (25 Nov 2008)
- If a HTTP request is Basic and num is already >=1000, the HTTP test
server adds 1 to num to get the data section to return. This allows
testing authentication negotiations using the Basic authentication
- Added tests 1087 and 1088 to test Basic authentication on a redirect
with and without --location-trusted
Daniel Stenberg (24 Nov 2008)
- Based on a patch by Vlad Grachov, libcurl now uses a new libssh2 0.19
function when built to support SCP and SFTP that helps the library to know
in which direction a particular libssh2 operation would return EAGAIN so
that libcurl knows what socket conditions to wait for before trying the
function call again. Previously (and still when using libssh2 0.18 or
earlier), libcurl will busy-loop in this situation when the easy interface
is used!
Daniel Fandrich (20 Nov 2008)
- Automatically detect OpenBSD's CA cert bundle.
Daniel Stenberg (19 Nov 2008)
- I removed the default use of "Pragma: no-cache" from libcurl when a proxy is
used. It has been used since forever but it was never a good idea to use
unless explicitly asked for.
- Josef Wolf's extension that allows a $TESTDIR/gdbinit$testnum file that when
you use -g, will be sourced by gdb to allow additional fancy or
whatever you see fit
- Christian Krause reported and fixed a memory leak that would occur with HTTP
GSS/kerberos authentication (
- Andreas Wurf and Markus Koetter helped me analyze a problem that Andreas got
when uploading files to a single FTP server using multiple easy handle
handles with the multi interface. Occasionally a handle would stall in
mysterious ways.
The problem turned out to be a side-effect of the ConnectionExists()
function's eagerness to re-use a handle for HTTP pipelining so it would
select it even if already being in use, due to an inadequate check for its
chances of being used for pipelnining.
Daniel Fandrich (17 Nov 2008)
- Added more compiler warning options for gcc 4.3
Yang Tse (17 Nov 2008)
- Fix a remaining problem in the inet_pton() runtime configure check. And
fix internal Curl_inet_pton() failures to reject certain malformed literals.
- Make configure script check if ioctl with the SIOCGIFADDR command can be
used, and define HAVE_IOCTL_SIOCGIFADDR if appropriate.
Daniel Stenberg (16 Nov 2008)
- Christian Krause fixed a build failure when building with gss support
enabled and FTP disabled.
- Added check for NULL returns from strdup() in src/main.c and lib/formdata.c
- reported by Jim Meyering also prevent buffer overflow on MSDOS when you do
for example -O on a url with a file name part longer than PATH_MAX letters
- lib/nss.c fixes based on the report by Jim Meyering: I went over and added
checks for return codes for all calls to malloc and strdup that were
missing. I also changed a few malloc(13) to use arrays on the stack and a
few malloc(PATH_MAX) to instead use aprintf() to lower memory use.
- I fixed a memory leak in Curl_nss_connect() when CURLOPT_ISSUERCERT is
in use.
Daniel Fandrich (14 Nov 2008)
- Added .xml as one of the few common file extensions known by the multipart
form generator.
- Added some #ifdefs around header files and change the EAGAIN test to
fix compilation on Cell (reported by Jeff Curley).
Yang Tse (14 Nov 2008)
- Fixed several configure script issues affecting checks for inet_ntoa_r(),
inet_ntop(), inet_pton(), getifaddrs(), fcntl() and getaddrinfo().
Yang Tse (13 Nov 2008)
- Refactored configure script detection of functions used to set sockets into
non-blocking mode, and decouple function detection from function capability.
Version 7.19.2 (13 November 2008)
Michal Marek (13 Nov 2008)
- Fixed a potential data loss in Curl_client_write() when the transfer is
Daniel Stenberg (11 Nov 2008)
- Rainer Canavan filed bug #2255627
( which pointed out that a
program using libcurl's multi interface to download a HTTPS page with a
libcurl built powered by OpenSSL, would easily get silly and instead hand
over SSL details as data instead of the actual HTTP headers and body. This
happened because libcurl would consider the connection handshake done too
early. This problem was introduced at September 22nd 2008 with my fix of the
bug #2107377
The correct fix is now instead done within the GnuTLS-handling code, as both
the OpenSSL and the NSS code already deal with this situation in similar
fashion. I added test case 560 in an attempt to verify this fix, but
unfortunately it didn't trigger it even before this fix!
Yang Tse (11 Nov 2008)
- Related with bug #2230535 (
Daniel Fandrich noticed that curl_addrinfo was also missing in the build
process of other four non-configure platforms. Added now.
Daniel Fandrich (7 Nov 2008)
- The getifaddrs() version of Curl_if2ip() crashed when used on a Linux
system with a TEQL load-balancing device configured, which doesn't
have an address. Thanks to Adam Sampson for spotting this (bug #2234923).
Yang Tse (6 Nov 2008)
- Merged existing IPv4 and IPv6 Curl_ip2addr functions into a single one
which now also takes a protocol address family argument.
- Bug #2230535 ( pointed out a
problem with MSVC 6 makefile that caused a build failure. It was noted that
the curl_addrinfo.obj reference was missing. I took the opportunity to sort
the list in which this was missing. Issue submitted by John Wilkinson.
Version 7.19.1 (5 November 2008)
Daniel Stenberg (4 Nov 2008)
- CURLINFO_FILETIME now works for file:// transfers as well
Daniel Stenberg (3 Nov 2008)
- Bug #2218480 ( pointed out a
problem with my CURLINFO_PRIMARY_IP fix from October 7th that caused a NULL
pointer read. I also took the opportunity to clean up this logic (storing of
the connection's IP address) somewhat as we had it stored in two different
places and ways previously and they are now unified.
Yang Tse (3 Nov 2008)
- Fix undersized IPv6 address internal buffer. IPv6 address strings longer
than 35 characters would be truncated.
Daniel Stenberg (2 Nov 2008)
- Daniel Johnson reported and fixed:
When c-ares isn't enabled, libcurl by default calls getaddrinfo with family
set to PF_UNSPEC which causes getaddrinfo to return all available addresses,
both IPv4 and IPv6. Libcurl then tries each one until it can connect. If the
net connection doesn't support IPv6, libcurl can still fall back to IPv4.
However, since c-ares doesn't support PF_UNSPEC, when it's used it defaults
to using family=PF_INET6 and therefore only returns IPv6 addresses when AAAA
records are available, even if IPv4 addresses are also available. The effect
is that since my ISP doesn't do IPv6, libcurl can't connect at all to a site
that has AAAA records. It will work if I explicitly use CURL_IPRESOLVE_V4 or
--ipv4 with the curl tool. I discovered this when curl would fail to connect
to seemingly random sites. It turns out they weren't random, they were sites
with AAAA records.
So now libcurl defaults to PF_INET... until c-ares has been tought to offer
Yang Tse (31 Oct 2008)
- Tests 558 and 559 are stabilized. These two tests were initially introduced
to aid in the location of a seg-fault which was only triggered on non-debug
builds done with the icc 9.1 Intel compiler. Test 558 does not trigger the
problem, but test 559 does trigger it. As of today, it isn't yet absolutely
clear if it is a compiler optimizer issue or a memory corruption one.
Yang Tse (30 Oct 2008)
- Use our Curl_addrinfo structure definition to handle address info data even
when a system addrinfo struct is available. Provide and use a wrapper around
systems getaddrinfo function, Curl_getaddrinfo_ex which returns a pointer to
a list of dynamically allocated Curl_addrinfo structs.
Configure will check freeaddrinfo and getaddrinfo functions and define
preprocessor symbols HAVE_FREEADDRINFO and HAVE_GETADDRINFO when appropriate.
Daniel Fandrich (29 Oct 2008)
- Fixed a bug that caused a few bytes of garbage to be sent after a
curl_easy_pause() during a chunky upload. Reported by Steve Roskowski.
Daniel Fandrich (28 Oct 2008)
- Changed the "resolve" test precheck program to verify that an IPv6 socket
can be created before resolving the IPv6 name. In the context of running
a test, it doesn't make sense to run an IPv6 test when a host is resolvable
but IPv6 isn't usable. This should fix failures of test 1085 on hosts with
library and DNS support for IPv6 but where actual use of IPv6 has been
administratively disabled.
Daniel Fandrich (24 Oct 2008)
- Added experimental support for zlib and OpenSSL on Symbian OS.
Daniel Fandrich (21 Oct 2008)
- Fixed some problems with SFTP range support to fix test cases 634 through
Daniel Fandrich (17 Oct 2008)
- Fixed a compile error reported by Albert Chin on AIX and IRIX when using
Daniel Stenberg (16 Oct 2008)
- Igor Novoseltsev added CURLOPT_PROXYUSER and CURLOPT_PROXYPASSWORD that then
make CURLOPT_PROXYUSERPWD sort of deprecated. The primary motive for adding
these new options is that they have no problems with the colon separator
that the CURLOPT_PROXYUSERPWD option does.
Daniel Stenberg (15 Oct 2008)
- Pascal Terjan filed bug #2154627
( which pointed out that libcurl
uses strcasecmp() in multiple places where it causes failures when the
Turkish locale is used. This is because 'i' and 'I' isn't the same letter so
strcasecmp() on those letters are different in Turkish than in English (or
just about all other languages). I thus introduced a totally new internal
function in libcurl (called Curl_raw_equal) for doing case insentive
comparisons for english-(ascii?) style strings that thus will make "file"
and "FILE" match even if the Turkish locale is selected.
Daniel Fandrich (15 Oct 2008)
- A <precheck> command is considered to have failed if it returns a non-zero
return code. This way, if the precheck command can't be run at all for
whatever reason, it's treated as a precheck failure which causes the
test to be skipped.
Daniel Stenberg (15 Oct 2008)
- John Wilkinson filed bug #2155496
( pointing out an error case
without a proper human-readable error message. When a read callback returns
a too large value (like when trying to return a negative number) it would
trigger and the generic error message then makes the proplem slightly
different to track down. I've added an error message for this now.
Daniel Fandrich (9 Oct 2008)
- Fixed the --interface option to work with IPv6 connections on glibc
systems supporting getifaddrs(). Also fixed a problem where an IPv6
address could be chosen instead of an IPv4 one for --interface when it
involved a name lookup.
Daniel Fandrich (8 Oct 2008)
- Added tests 1082 through 1085 to test symbolic --interface parameters
- Added tests 633 through 637 to test the new file range support for SFTP.
All but the first test cause an infinite loop or other failure and so
are added to DISABLED.
Daniel Stenberg (8 Oct 2008)
- John Wilkinson filed bug #2152270
( which identified and fixed a
CURLINFO_REDIRECT_URL memory leak and an additional wrong-doing:
Any subsequent transfer with a redirect leaks memory, eventually crashing
the process potentially.
Any subsequent transfer WITHOUT a redirect causes the most recent redirect
that DID occur on some previous transfer to still be reported.
- Igor Novoseltsev filed bug #2111613
( that eventually identified a
flaw in how the multi_socket interface in some cases missed to call the
timeout callback when easy interfaces are removed and added within the same
- Igor Novoseltsev brought a patch that introduced two new options to
curl_easy_setopt: CURLOPT_USERNAME and CURLOPT_PASSWORD that sort of
deprecates the good old CURLOPT_USERPWD since they allow applications to set
the user name and password independently and perhaps more importantly allow
both to contain colon(s) which CURLOPT_USERPWD doesn't fully support.
Daniel Fandrich (7 Oct 2008)
- Changed the handling of read/write errors in Curl_perform() to allow a
a fresh connection to be made in such cases and the request retransmitted.
This should fix test case 160. Added test case 1079 in an attempt to
test a similar connection dropping scenario, but as a race condition, it's
hard to test reliably.
- Created test cases 1080 and 1081 to reproduce a problem of
CURLINFO_REDIRECT_URL leaking memory and returning incorrect results when
two URLs are requested. Reported by vmpdemo in bug #2152270
Daniel Stenberg (7 Oct 2008)
- Fixed CURLINFO_PRIMARY_IP: When libcurl created a connection to host A then
the app re-used the handle to do a connection to host B and then again
re-used the handle to host A, it would not update the info with host A's IP
address (due to the connection being re-used) but it would instead report
the info from host B.
Yang Tse (7 Oct 2008)
- Added --enable-optimize configure option to enable and disable compiler
optimizations to allow decoupled setting from --enable-debug.
Yang Tse (2 Oct 2008)
- Added --enable-warnings configure option to enable and disable strict
compiler warnings to allow decoupled setting from --enable-debug. will now run with picky compiler warnings enabled unless
explicitly disabled.
Daniel Fandrich (1 Oct 2008)
- "make clean" now cleans out the docs and tests directories, too.
Daniel Stenberg (30 Sep 2008)
- The libcurl FTP code now returns CURLE_REMOTE_FILE_NOT_FOUND error when SIZE
gets a 550 response back for the cases where a download (or NOBODY) is
wanted. It still allows a 550 as response if the SIZE is used as part of an
upload process (like if resuming an upload is requested and the file isn't
there before the upload). I also modified the FTP test server and a few test
cases accordingly to match this modified behavior.
Daniel Stenberg (29 Sep 2008)
- Daniel Egger provided a patch that allows you to disable proxy support in
libcurl to somewhat reduce the size of the binary. Run configure

- Make sure not to dereference the wrong UrlState proto union member when
switching from one protocol to another in a single request (e.g.
redirecting from HTTP to FTP as in test 1055) by resetting
state.expect100header before every request.
Daniel Stenberg (23 Sep 2008)
- Introducing Jamie Lokier's function for date to epoch conversion used in the
date parser function. This makes our function less dependent on system-
provided functions and instead we do all the magic ourselves. We also no
longer depend on the TZ environment variable. Switching to our own converter
has some side-effect and they are noted here for future reference (taken
from a mail by mr Lokier):
time_t is not measured in seconds in the ANSI C standard - or even counted
uniformly - weird platforms can use other numeric representations of dates
in time_t - hence the difftime() function.
On POSIX time_t is measured in UTC seconds, which means not including leap
seconds. But it's mentioned in a few places that some old POSIX-ish
environments include leap seconds in their time_t counts...
I'm pretty sure [the new implementation is] correct on anything truly POSIX.
And it's obviously a lot less dependent on platform quirks and corner cases
in many ways than the mktime() version.

Daniel Stenberg (22 Sep 2008)
- Made the SOCKS code use the new Curl_read_plain() function to fix the bug
Markus Moeller reported:
- recv() errors other than those equal to EAGAIN now cause proper
CURLE_RECV_ERROR to get returned. This made test case 160 fail so I've now
disabled it until we can figure out another way to exercise that logic.
- Michael Goffioul filed bug report #2107377 "Problem with multi + GnuTLS +
proxy" ( that showed how a multi
interface using program didn't work when built with GnuTLS and a CONNECT
request was done over a proxy (basically test 502 over a proxy to a HTTPS
site). It turned out the ssl connect function would get called twice which
caused the second call to fail.

- configure script now checks availability of the alarm() function.
Daniel Fandrich (18 Sep 2008)
- Don't bother to install a SIGALRM handler unless alarm() is available.
Also, leave the existing SIGALRM handler alone if the timeout is too small
to handle.
Daniel Fandrich (17 Sep 2008)
- Removed reference to curl-ca-bundle.crt in the host verification failure
error message.
Yang Tse (17 Sep 2008)
- Improve configure detection of gethostname(), localtime_r(), strstr(),
getservbyport_r(), gethostbyaddr_r() and gethostbyname_r().
Yang Tse (14 Sep 2008)
- Improve configure detection of strcasecmp(), strcasestr(), strcmpi(),
stricmp(), strlcat(), strncasecmp(), strncmpi() and strnicmp().
Yang Tse (13 Sep 2008)
- Disable tracking of fdopen() calls in the low-level memory leak tracking
code when fdopen() is not available, to avoid compiler error.
Yang Tse (12 Sep 2008)
- Further adjust detection of strerror_r() in the configure process, and
ensure that errno is not modified inside Curl_strerror().
Yang Tse (10 Sep 2008)
- Improve detection of gmtime_r(), strtoll(), sigaction(), strtok_r(),
strdup() and ftruncate() in the configure process.
Daniel Fandrich (9 Sep 2008)
- Mike Revi discovered some swapped speed switches documented in the curl man
- Checked in some documentation and code improvements and fixes that I
discovered in the FreeBSD ports system.
Daniel Stenberg (8 Sep 2008)
- Dmitry Kurochkin patched a problem: I have found bug in pipelining through
proxy. I have a transparent proxy. When running with http_proxy environment
variable not set my test completes fine (it goes through transparent
proxy). When I set http_proxy variable my test hangs after the first
downloaded is complete. Looks like the second handle never gets out from
WAITDO state.
The fix: It makes checkPendPipeline move 1 handler from pend pipe to send
pipe if pipelining is not supported by server but there are no handles in
send and recv pipes.
- Stefan Krause pointed out that libcurl would wrongly send away cookies to
sites in cases where the cookie clearly has a very old expiry date. The
condition was simply that libcurl's date parser would fail to convert the
date and it would then count as a (timed-based) match. Starting now, a
missed date due to an unsupported date format or date range will now cause
the cookie to not match.
Daniel Fandrich (5 Sep 2008)
- Improved the logic that decides whether to use HTTP 1.1 features or not in a
request. Setting a specific version with CURLOPT_HTTP_VERSION overrides
all other checks, but otherwise, a 1.0 request will be made if the server
is known to support only 1.0 because it previously responded so and the
connection was kept alive, or a response to a previous request on this handle
came back as 1.0. The latter could take place in cases like redirection or
authentication where several requests have to be made before the operation
is complete. If any one of the servers in a redirection chain supports only
1.0, then remaining requests will be sent in 1.0 mode.
- Detect cases where an upload must be sent chunked and the server supports
only HTTP 1.0 and return CURLE_UPLOAD_FAILED.
Daniel Stenberg (5 Sep 2008)
- Martin Drasar provided the CURLOPT_POSTREDIR patch. It renames
CURLOPT_POST301 (but adds a define for backwards compatibility for you who
don't define CURL_NO_OLDIES). This option allows you to now also change the
libcurl behavior for a HTTP response 302 after a POST to not use GET in the
subsequent request (when CURLOPT_FOLLOWLOCATION is enabled). I edited the
patch somewhat before commit. The curl tool got a matching --post302
option. Test case 1076 was added to verify this.
- Introducing CURLOPT_CERTINFO and the corresponding CURLINFO_CERTINFO. By
enabling this feature with CURLOPT_CERTINFO for a request using SSL (HTTPS
or FTPS), libcurl will gather lots of server certificate info and that info
can then get extracted by a client after the request has completed with
curl_easy_getinfo()'s CURLINFO_CERTINFO option. Linus Nielsen Feltzing
helped me test and smoothen out this feature.
Unfortunately, this feature currently only works with libcurl built to use
This feature was sponsored by - thanks!
- Dmitriy Sergeyev pointed out that curl_easy_pause() didn't unpause properly
during certain conditions. I also changed this code to use realloc() based
on Daniel Fandrich's suggestion.
Guenter Knauf (4 Sep 2008)
- MingW32 non-configure builds are now largefile feature enabled by default.
NetWare LIBC builds are also now largefile feature enabled by default.
Yang Tse (4 Sep 2008)
- Several fixes related with print formatting string directives.
Daniel Fandrich (3 Sep 2008)
- Search for the FreeBSD CA cert file /usr/local/share/certs/ca-root.crt
Daniel Fandrich (2 Sep 2008)
- Fixed an out of memory problem that caused torture test failures in tests
706 and 707.
Daniel Stenberg (2 Sep 2008)
- Keith Mok added supported_protocols and supported_features to the pkg-config
file for libcurl, and while doing that fix he unified with
how the supported protocols and features are extracted and used, so both those
tools should now always be synced.
Version 7.19.0 (1 September 2008)
Daniel Fandrich (29 Aug 2008)
- Added tests 1071 through 1074 to test automatic downgrading from HTTP 1.1
to HTTP 1.0 upon receiving a response from the HTTP server. Tests 1072
and 1073 are similar to test 1069 in that they involve the impossible
scenario of sending chunked data to a HTTP 1.0 server. All these fail
and are added to DISABLED.
- Added test 1075 to test --anyauth with Basic authentication.
Daniel Stenberg (29 Aug 2008)
- When libcurl was doing a HTTP POST and the server would respond with
"Connection: close" and actually close the connection after the
response-body, libcurl could still have outstanding data to send and it
would not properly notice this and stop sending. This caused weirdness and
sad faces.
Note that there are still reasons to consider libcurl's behavior when
getting a >= 400 response code while sending data, as Craig Perras' note
"http upload: how to stop on error" specifies:
Daniel Stenberg (28 Aug 2008)
- Dengminwen reported that libcurl would lock a (cookie) share twice (without
an unlock in between) for a certain case and that in fact works when using
regular windows mutexes but not with pthreads'! Locks should of course not
get locked again so this is now fixed.
- I'm abandoning the system with the web site mirrors (but keeping download
files bing mirrored) and thus I've changed the URL in the cookiejar header
to no longer use but instead use the main site
Daniel Fandrich (27 Aug 2008)
- Fixed test case 1065 by changing the handling of CURLOPT_UPLOAD to set
the HTTP method to GET (or HEAD) when given a value of 0.
- Added test cases 1068 and 1069 to test a simple HTTP PUT from stdin. Test
case 1069 fails in a similar manner to test 1065 so is added to DISABLED.
Yang Tse (27 Aug 2008)
- Fix generation of MS VC6 .dsp file to make it support compilation of either
dynamic (DLL) or static (LIB) libcurl libraries in debug and release modes.
Daniel Fandrich (26 Aug 2008)
- Fixed out of memory problems that caused torture test failures in tests
1021 and 1067.
Yang Tse (26 Aug 2008)
- Added check and symbol definition for WIN32 file API usage in configure,
supporting configure's --disable-largefile option for WIN32 targets also.
- Non-configure systems which do not use config-win32.h configuration file,
and want to use the WIN32 file API, must define USE_WIN32_LARGE_FILES or
USE_WIN32_SMALL_FILES as appropriate in their own configuration files.
Daniel Stenberg (23 Aug 2008)
- Running 'make ca-firefox' in the root build dir will now run the new conversion script that converts a local Firefox db of ca
certs into PEM format, suitable for use with a OpenSSL or GnuTLS built
- Constantine Sapuntzakis fixed a bug when doing proxy CONNECT with the multi
interface, and the proxy would send Connection: close during the
authentication phase.
Daniel Fandrich (22 Aug 2008)
- Fixed a problem when --dump-header - was given with more than one URL,
which caused an error when the second header was dumped due to stdout
being closed. Added test case 1066 to verify. Also fixed a potential
problem where a closed file descriptor might be used for an upload
when more than one URL is given.
Yang Tse (22 Aug 2008)
- Improved libcurl's internal curl_m*printf() functions integral data type
size and signedness handling.
- Internal adjustments to better select/differentiate when large/small file
support is provided using WIN32 functions directly.
Daniel Fandrich (20 Aug 2008)
- Added an edited version of Vincent Le Normand's documentation of SFTP quote
commands to the man pages.
Daniel Stenberg (20 Aug 2008)
- Phil Pellouchoud pointed out that the windows version of libcurl had a
memory leak because it never called the OpenSSL function
CRYPTO_cleanup_all_ex_data() as it was supposed to. This was because of a
missing define in config-win32.h!
Gisle Vanem (18 Aug 2008)
- Updated lib/Makefile.Watcom with the option to use c-ares (USE_ARES=1).
Yang Tse (18 Aug 2008)
- Added test case 557 to verify libcurl's internal curl_m*printf() functions
formatting functionality when handling signed and unsigned longs, as well as
our curl_off_t data type.
Yang Tse (17 Aug 2008)
- OpenSSl enabled NetWare builds are changed to use the 'openssl' subdirectory
when including the OpenSSL header files. This is the recommended setting, this
prevents the undesired inclusion of header files with the same name as those
of OpenSSL but which do not belong to the OpenSSL package. The visible change
from previously released libcurl versions is that now OpenSSl enabled NetWare
builds also define USE_OPENSSL in config files, and that OpenSSL header files
must be located in a subdirectory named 'openssl'.
Yang Tse (16 Aug 2008)
- Library internal only C preprocessor macros FORMAT_OFF_T and FORMAT_OFF_TU
remain in use as internal curl_off_t print formatting strings for the internal
*printf functions which still cannot handle print formatting string directives
such as "I64d", "I64u", and others available on MSVC, MinGW, Intel's ICC, and
other DOS/Windows compilers.
Daniel Fandrich (15 Aug 2008)
- Added test case 1063 to test invalid long file ranges with file: URLs and
1064 to test multiple http PUTs.
- Added test case 1065 to test a PUT with a single file but two URLs. This
was discovered to be problematic while investigating an incident reported by
Von back in May. curl in this case doesn't include a Content-Length: or
Transfer-Encoding: chunked header which is illegal. This test case is
added to DISABLED until a solution is found.
Yang Tse (15 Aug 2008)
- C preprocessor macros used internally and equally available externally which
aid in the use of the curl_off_t data type are named: CURL_FORMAT_CURL_OFF_T,
Yang Tse (13 Aug 2008)
- The size of long is a build time characteristic and as such it is now recorded
in curlbuild.h as CURL_SIZEOF_LONG. Definition now done from configure process
and in CVS curlbuild.h.dist for non-configure systems.
Daniel Fandrich (12 Aug 2008)
- Fixed a buffer overflow problem in Curl_proxyCONNECT that could occur
when a server responded with long headers and data. Luckily, the buffer
overflowed into another unused buffer, so no actual harm was done.
Added test cases 1060 and 1061 to verify.
Daniel Stenberg (12 Aug 2008)
- Andy Tsouladze fixed to not attempt to execute the stunnel
_directory_ if that happened to appear in the path!
Yang Tse (12 Aug 2008)
- Added macros for minimum-width signed and unsigned curl_off_t integer
constants CURL_OFF_T_C and CURL_OFF_TU_C. The clever double helper macro
used internally to provide its functionality is thanks to Lars Nilsson.
Daniel Fandrich (11 Aug 2008)
- Fixed a boundary condition error in ftp_readresp() whereby a non-terminal
line of a multiline FTP response whose last byte landed exactly at the end
of the BUFSIZE-length buffer would be treated as the terminal response
line. The following response code read in would then actually be the
end of the previous response line, and all responses from then on would
correspond to the wrong command. Test case 1062 verifies this.
- Stop closing a never-opened ftp socket.
Daniel Stenberg (11 Aug 2008)
- Constantine Sapuntzakis filed bug report #2042430
( with a patch. "NTLM Windows
SSPI code is not thread safe". This was due to libcurl using static
variables to tell wether to load the necessary SSPI DLL, but now the loading
has been moved to the more suitable curl_global_init() call.
- Constantine Sapuntzakis filed bug report #2042440
( with a patch. He identified a
problem when using NTLM over a proxy but the end-point does Basic, and then
libcurl would do wrong when the host sent "Connection: close" as the proxy's
NTLM state was erroneously cleared.
Yang Tse (11 Aug 2008)
- Added missing signed and unsigned curl_off_t integer constant suffixes for
internal and external use. CURL_SUFFIX_CURL_OFF_T, CURL_SUFFIX_CURL_OFF_TU.
Daniel Fandrich (7 Aug 2008)
- Fixed an uninitialized variable in multi_runsingle() that could cause a
request to prematurely end.
- Added test1059 to test the FTP proxy tunnel problem fixed July 11.
Yang Tse (7 Aug 2008)
- Added curlbuild.h and curlrules.h header files to libcurl's public headers.
File curlbuild.h is a generated file on configure-capable systems. This is
a first step towards configure-based info in public headers. Currently only
used to provide support for a curl_off_t data type which is not gated to
off_t. Further details are documented inside these mentioned header files.
- Fix CURL_CHECK_DEF so that when the expansion of the preprocessor symbol
results in a set of double-quoted strings, this macro will now return an
expansion which consists of a single double-quoted string as the result of
concatenating all of them.
- Skip data type check in DO_CURL_OFF_T_CHECK macro when argument is empty.
- Adjusted to copy checked out curlbuild.h.dist as curlbuild.h
for non-configure targets when the host system doesn't run buildconf.bat.
- Prevent buildconf from removing 'Makefile' and 'missing' files. This would
blow away our CVS checked files 'missing' and 'hiper/Makefile'.
- Remove adjustment done to to verify if change introduced by
Guenter Knauf in lib/Makefile.netware is enough to get the netware autobuilds
going again.
Yang Tse (5 Aug 2008)
- Changes done to buildconf script. Validate that autom4te and autoconf, as
well as aclocal and automake, versions match. Improve removal of previous
run generated files. Remove verbose debug logging of aclocal on Solaris.
Daniel Stenberg (5 Aug 2008)
- Yehoshua Hershberg found a problem that would make libcurl re-use a
connection with the multi interface even if a previous use of it caused a
CURLE_PEER_FAILED_VERIFICATION to get returned. I now make sure that failed
SSL connections properly close the connections.
Daniel Stenberg (4 Aug 2008)
- Test cases 1051, 1052 and 1055 were added by Daniel Fandrich on July 30 and
proved how PUT and POST with a redirect could lead to a "hang" due to the
data stream not being rewound properly when it had to in order to get sent
properly (again) to the subsequent URL. This is now fixed and these test
cases are no longer disabled.
Yang Tse (4 Aug 2008)
- Autoconf 2.62 has changed the behaviour of the AC_AIX macro which we use.
Prior versions of autoconf defined _ALL_SOURCE if _AIX was defined. 2.62
version of AC_AIX defines _ALL_SOURCE and other four preprocessor symbols
no matter if the system is AIX or not. To keep the traditional behaviour,
and an uniform one across autoconf versions AC_AIX is replaced with our
own internal macro CURL_CHECK_AIX_ALL_SOURCE.
Daniel Stenberg (4 Aug 2008)
- Test case 1041 (added by Daniel Fandrich July 14th) proved a bug where PUT
with -C - sent garbage in the Content-Range: header. I fixed this problem by
making sure libcurl always sets the size of the _entire_ upload if an app
attemps to do resumed uploads since libcurl simply cannot know the size of
what is currently at the server end. Test 1041 is no longer disabled.
Yang Tse (2 Aug 2008)
- No longer test availability of the gdi32 library, nor use it for linking, even
when we have been doing this since revision 1.47 of 4 years and
5 months ago when cross-compiling a Windows target. We actually don't use any
function from the Windows GDI (Graphics Device Interface) related with drawing
or graphics-related operations.
Daniel Fandrich (1 Aug 2008)
- Added support for --append on SFTP uploads. Unfortunately, OpenSSH doesn't
support this so it goes untested.
Yang Tse (1 Aug 2008)
- Configure process now checks if the preprocessor _REENTRANT symbol is already
defined. If it isn't currently defined a set of checks are performed to test
if its definition is required to make visible to the compiler a set of *_r
functions. Finally, if _REENTRANT is already defined or needed it takes care
of making adjustments necessary to ensure that it is defined equally for the
configure process tests and generated config file.
- Removed definition of CURL_CHECK_WORKING_RESOLVER from acinclude.m4 it has
not been in use since revision 1.81 of 6 years, 9 months ago.
Daniel Fandrich (31 Jul 2008)
- Fixed parsing of an IPv6 proxy address to support a scope identifier,
as well as IPv4 addresses in IPv6 format. Also, better handle the case
of a malformatted IPv6 address (avoid empty and NULL strings).
- Fixed a problem with any FTP URL or any URLs containing an IPv6 address
being mangled when passed to proxies when CURLOPT_PORT is also set
(reported by Pramod Sharma).
- User names embedded in proxy URLs without a password were parsed
incorrectly--the host name is treated as part of the user name and the
port number becomes the password. This can be observed in test 279
(was KNOWN_ISSUE #54).
Daniel Stenberg (30 Jul 2008)
- Phil Blundell added the CURLOPT_ADDRESS_SCOPE option, as well as adjusted
the URL parser to allow numerical IPv6-addresses to be specified with the
scope given, as per RFC4007 - with a percent letter that itself needs to be
URL escaped. For example, for an address of fe80::1234%1 the HTTP URL is:
- PHP's bug report #43158 ( identifies a
true bug in libcurl built with OpenSSL. It made curl_easy_getinfo() more or
less always return 0 for CURLINFO_SSL_VERIFYRESULT because the function that
would set it to something non-zero would return before the assign in almost
all error cases. The internal variable is now set to non-zero from the start
of the function only to get cleared later on if things work out fine.
- Made the curl tool's -w option support the %{ssl_verify_result} variable
Daniel Fandrich (30 Jul 2008)
- Added test cases 1052 through 1055 to test uploading data from files
during redirects. Test cases 1052 and 1055 show problems (maybe the same
root cause as 1051) and are disabled.
- Fixed a couple of buffer overflows in the MS-DOS port of the curl tool.
Daniel Fandrich (29 Jul 2008)
- Fixed --use-ascii to properly convert text files on Symbian OS, MS-DOS
and OS/2.
- Added test case 1051 to test Location: following with PUT, as reported
by Ben Sutcliffe. The test when run manually shows a problem in curl
so it's disabled.
Daniel Fandrich (28 Jul 2008)
- Fixed display of the interface bind address in the trace output when it's
an IPv6 address.
- Added test cases 1045 through 1049 as simple tests of --interface using the
localhost interface.
- Added test case 1050 to test --ftp-port with an IPv6 address
Daniel Stenberg (26 Jul 2008)
- David Bau filed bug report #2026240 "CURL_READFUNC_PAUSE leads to buffer
overrun" ( identifying two
problems, and providing the fix for them:
- CURL_READFUNC_PAUSE did in fact not pause the _sending_ of data that it is
designed for but paused _receiving_ of data!
- libcurl didn't internally set the read counter to zero when this return
code was detected, which would potentially lead to junk getting sent to
the server.
Daniel Fandrich (26 Jul 2008)
- Added test 1044 to test large file support in ftp with -I.
- Eliminate a unnecessary socket creation in Curl_getaddrinfo for an IPv4
address in an IPv6 capable libcurl.
- Added feature in to select tests based on key word.
Daniel Fandrich (23 Jul 2008)
- Changed the long logfile elision code in to properly handle
lines ending in \r.
- Changed references to TRUE and FALSE in the curl_easy_setopt man page to
1 and zero, respectively, since TRUE and FALSE aren't part of the
libcurl API.
Daniel Stenberg (23 Jul 2008)
- I went over the curl_easy_setopt man page and replaced most references to
non-zero with the fixed value of 1. We should strive at making options
support '1' for enabling them mentioned explicitly, as that then will allow
us for to extend them in the future without breaking older programs.
Possibly we should even introduce a fancy define to use instead of '1' all
Yang Tse (21 Jul 2008)
- Use the sreadfrom() wrapper to replace recvfrom() in our code.
Yang Tse (20 Jul 2008)
- when recvfrom prototype uses a void pointer for arguments 2, 5 or 6 this will
now cause the definition, as appropriate, of RECVFROM_TYPE_ARG2_IS_VOID,
Yang Tse (17 Jul 2008)
to the data type pointed by its respective argument and not the pointer type.
Yang Tse (16 Jul 2008)
- Configure process now checks availability of recvfrom() socket function and
finds out its return type and the types of its arguments. Added definitions
for non-configure systems config files, and introduced macro sreadfrom which
will be used on udp sockets as a recvfrom() wrapper.
Yang Tse (15 Jul 2008)
- Added description/comment to include paths used in several files.
Added automake option nostdinc to test servers makefile and modified libcurl
external headers include path for libtest programs.
Daniel Fandrich (14 Jul 2008)
- Added test1040 through test1043 to test -C - on HTTP. Test 1041 failed so
it's added to DISABLED.
Yang Tse (14 Jul 2008)
- HTTP_ONLY definition check in lib/setup.h is now done once that configuration
file has been included. In this way if symbol is defined in the config file
it will no longer be ignored. Removed inclusion of remaining system header
files from configuration files. Moved _REENTRANT definition up/earlier in
Yang Tse (11 Jul 2008)
- Added missing multiple header inclusion prevention definition for header
file content_encoding.h
Daniel Fandrich (11 Jul 2008)
- Fixed test 553 to pass the torture test.
Daniel Stenberg (11 Jul 2008)
- Daniel Fandrich found out we didn't pass on the user-agent properly when
doing "proxy-tunnels" with non-HTTP prototols and that was simply because
the code assumed the user-agent was only needed for HTTP.
Daniel Fandrich (10 Jul 2008)
- Changed slightly the SFTP quote commands chmod, chown and chgrp to only
set the attribute that has changed instead of all possible ones. Hopefully,
this will solve the "Permission denied" problem that Nagarajan Sreenivasan
reported when setting some modes, but regardless, it saves a protocol
round trip in the chmod case.
- Added test cases 1038 and 1039 to test Adrian Kreher's report that ftp
uploads with -C - didn't resume properly, but the tests pass.
Yang Tse (10 Jul 2008)
- Peter Lamberg filed bug report #2015126: "poll gives WSAEINVAL when POLLPRI
is set in" ( which
exactly pinpointed the problem only triggered on Windows Vista, provided
reference to docs and also a fix. There is much work behind Peter Lamberg's
excellent bug report. Thank You!
Daniel Fandrich (9 Jul 2008)
- Added tests 1036 and 1037 to verify resumed ftp downloads with -C -
Daniel Stenberg (9 Jul 2008)
- Andreas Schuldei improved Phil Blundell's patch for IPv6 using c-ares, and I
edited it slightly. Now you should be able to use IPv6 addresses fine even
with libcurl built to use c-ares.
Daniel Fandrich (9 Jul 2008)
- Fixed an OOM handling problem that cause test 11 to fail the torture test.
Daniel Fandrich (8 Jul 2008)
- Fixed test 554 to pass the torture test.
Daniel Fandrich (7 Jul 2008)
- Added test cases 1034 & 1035 to test IDN name conversion failures.
Daniel Stenberg (7 Jul 2008)
- Scott Barrett provided a test case for a segfault in the FTP code and the
fix for it. It occured when you did a FTP transfer using
CURLFTPMETHOD_SINGLECWD and then did another one on the same easy handle but
switched to CURLFTPMETHOD_NOCWD. Due to the "dir depth" variable not being
cleared properly. Scott's test case is now known as test 539 and it
verifies the fix.
Daniel Stenberg (3 Jul 2008)
- Phil Blundell provided a fix for libcurl's treatment of unexpected 1xx
response codes. Previously libcurl would hang on such occurances. I added
test case 1033 to verify.
- Introcuding a new timestamp for curl_easy_getinfo():
CURLINFO_APPCONNECT_TIME. This is set with the "application layer"
handshake/connection is completed. Which typically is SSL, TLS or SSH and by
using this you can figure out the application layer's own connect time. You
can extract the time stamp using curl's -w option and the new variable named
'time_appconnect'. This feature was sponsored by Lenny Rachitsky at NeuStar.
Daniel Fandrich (2 Jul 2008)
- Support Open Watcom C on Linux (as well as Windows).
Yang Tse (2 Jul 2008)
- The previously committed fix for bug report #1999181 prevented using the
monotonic clock on any system without an always supported POSIX compliant
implementation. Now the POSIX compliant configuration check is removed and
will fallback to gettimeofday when the monotonic clock is unavailable at
- The configure process will now halt when sed, grep, egrep or ar programs
can not be found among the directories in PATH variable.
Daniel Stenberg (1 Jul 2008)
- Rolland Dudemaine provided fixes to get libcurl to build for the INTEGRITY
operating system.
Daniel Stenberg (30 Jun 2008)
- Made the internal printf() support %llu properly to print unsigned long longs.
- Stephen Collyer and Tor Arntsen helped identify a flaw in the range code
which output the range using a signed variable where it should rather use
Yang Tse (29 Jun 2008)
- John Lightsey filed bug report #1999181: "CLOCK_MONOTONIC always fails on
some systems" ( The problem was
that the configure script did not use the _POSIX_MONOTONIC_CLOCK feature test
macro when checking monotonic clock availability. This is now fixed and the
monotonic clock will not be used unless the feature test macro is defined
with a value greater than zero indicating always supported.
Daniel Fandrich (25 Jun 2008)
- Honour --stderr with the -v option.
- Fixed a file handle leak in the command line client if more than one
--stderr option was given.
Daniel Stenberg (22 Jun 2008)
- Eduard Bloch filed the debian bug report #487567
( pointing out that
libcurl used Content-Range: instead of Range when doing a range request with
--head (CURLOPT_NOBODY). This is now fixed and test case 1032 was added to
Daniel Fandrich (21 Jun 2008)
- Stopped using ranges in scanf character sequences (e.g. %[a-z]) since that
is not ANSI C, just a common extension. This caused problems on
at least Open Watcom C.
Yang Tse (20 Jun 2008)
- Modified configuration script to actually verify if the compiler is good
enough at detecting compilation errors or at least it has been properly
configured to do so. Configuration heavily depends on this capability, so
if this compiler sanity check fails the configuration process will now fail.
Daniel Stenberg (20 Jun 2008)
- Phil Pellouchoud found a case where libcurl built with NSS failed to
handshake with a SSLv2 server, and it turned out to be because it didn't
recognize the cipher named "rc4-md5". In our list that cipher was named
plainly "rc4". I've now added rc4-md5 to work as an alias as Phil reported
that it made things work for him again.
- Hans-Jurgen May pointed out that trying SCP or SFTP over a SOCKS proxy
crashed libcurl. This is now addressed by making sure we use "plain send"
internally when doing the socks handshake instead of the Curl_write()
function which is designed to use the "target" protocol. That's then SCP or
SFTP in this case. I also took the opportunity and cleaned up some ssh-
related #ifdefs in the code for readability.
Daniel Stenberg (19 Jun 2008)
- Christopher Palow fixed a curl_multi_socket() issue which previously caused
libcurl to not tell the app properly when a socket was closed (when the name
resolve done by c-ares is completed) and then immediately re-created and put
to use again (for the actual connection). Since the closure will make the
"watch status" get lost in several event-based systems libcurl will need to
tell the app about this close/re-create case.
- Dengminwen found a bug in the connection re-use function when using the
multi interface with pipelining enabled as it would wrongly check for,
detect and close "dead connections" even though that connection was already
in use!
Daniel Fandrich (18 Jun 2008)
- Added SSH failure test cases 628-632
- Fixed a memory leak in the command-line tool that caused a valgrind error.
Daniel Stenberg (18 Jun 2008)
- Rob Crittenden brought a fix for the NSS layer that makes libcurl no longer
always fire up a new connection rather than using the existing one when the
multi interface is used. Original bug report:
Yang Tse (18 Jun 2008)
- Internal configure script improvement. No longer break out of shell "for"
statements from inside AC_FOO_IFELSE macros, otherwise temporary macro files
are not properly removed.
Daniel Fandrich (12 Jun 2008)
- Fixed curl-config --ca which wasn't being exported by configure.
Daniel Stenberg (11 Jun 2008)
- I did a cleanup of the internal generic SSL layer and how the various SSL
libraries are supported. Starting now, each underlying SSL library support
code does a set of defines for the 16 functions the generic layer (sslgen.c)
uses (all these new function defines use the prefix "curlssl_"). This
greatly simplified the generic layer in readability by involving much less
#ifdefs and other preprocessor stuff and should make it easier for people to
make libcurl work with new SSL libraries.
Hopefully I can later on document these 16 functions somewhat as well.
I also made most of the internal SSL-dependent functions (using Curl_ssl_
prefix) #defined to nothing when no SSL support is requested - previously
they would unnecessarily call mostly empty functions.
I've built libcurl with OpenSSL and GnuTLS and without SSL to test this and
I've also tried building with NSS but the NSS support is a mystery to me and
I failed to build libcurl with the NSS libraries I have installed. We really
should A) improve our configure script to detect unsuitable NSS versions
already at configure time and B) document our requirements better for the
SSL libraries.
Daniel Stenberg (10 Jun 2008)
- I made the OpenSSL code build again with OpenSSL 0.9.6. The CRLFILE
functionality killed it due to its unconditional use of
Daniel Stenberg (8 Jun 2008)
- Due to the three new libcurl changes and the massive command line option
change I decided we'll mark it by bumping the next release number to 7.19.0!
- curl the tool now deals with its command line options somewhat differently!
All boolean options (such as -O, -I, -v etc), both short and long versions,
now always switch on/enable the option named. Using the same option multiple
times thus make no difference. To switch off one of those options, you need
to use the long version of the option and type --no-OPTION. Like to disable
verbose mode you use --no-verbose!
- Added --remote-name-all to curl, which if used changes the default for all
given URLs to be dealt with as if -O is used. So if you want to disable that
for a specific URL after --remote-name-all has been used, you muse use -o -
or --no-remote-name.
Daniel Stenberg (6 Jun 2008)
- Axel Tillequin and Arnaud Ebalard added support for CURLOPT_ISSUERCERT, for
OpenSSL, NSS and GnuTLS-built libcurls.
- Axel Tillequin and Arnaud Ebalard added support for CURLOPT_CRLFILE, for
OpenSSL, NSS and GnuTLS-built libcurls.
- Added CURLINFO_PRIMARY_IP as a new information retrievable with
curl_easy_getinfo. It returns a pointer to a string with the most recently
used IP address. Modified test case 500 to also verify this feature. The
implementing of this feature was sponsored by Lenny Rachitsky at NeuStar.
Version 7.18.2 (4 June 2008)
Daniel Fandrich (3 Jun 2008)
- Fixed a problem where telnet data would be lost if an EWOULDBLOCK
condition were encountered.
Marty Kuhrt (1 Jun 2008)
- Updated main.c to return CURLE_OK if PARAM_HELP_REQUESTED was returned
from getparameter instead of CURLE_FAILED_INIT. No point in returning
an error if --help or --version were requested.
Daniel Stenberg (28 May 2008)
- Emil Romanus found a problem and helped me repeat it. It occured when using
the curl_multi_socket() API with HTTP pipelining enabled and could lead to
the pipeline basically stalling for a very long period of time until it took
off again.
- Jeff Weber reported memory leaks with aborted SCP and SFTP transfers and
provided excellent repeat recipes. I fixed the cases I managed to reproduce
but Jeff still got some (SCP) problems even after these fixes:
Daniel Stenberg (26 May 2008)
- Bug report #1973352 ( identified
how the HTTP redirect following code didn't properly follow to a new URL if
the new url was but a query string such as "Location: ?moo=foo". Test case
1031 was added to verify this fix.
- Andreas Faerber and Scott McCreary made (lib)curl build for the Haiku OS.
Yang Tse (26 May 2008)
- David Rosenstrauch reported that header files spnegohelp.h and
openssl/objects.h were needed to compile SPNEGO support.
Daniel Fandrich (22 May 2008)
- Made sure to pass longs in to curl_easy_setopt where necessary in the
example programs and libtest code.
Daniel Stenberg (19 May 2008)
- When trying to repeat a multi interface problem I fell over a few multi
interface problems:
o with pipelining disabled, the state should never be set to WAITDO but
rather go straight to DO
o we had multiple states for which the internal function returned no socket
at all to wait for, with the effect that libcurl calls the socket callback
(when curl_multi_socket() is used) with REMOVE prematurely (as it would be
added again within very shortly)
o when in DO and DOING states, the HTTP and HTTPS protocol handler functions
didn't return that the socket should be waited for writing, but instead it
was treated as if no socket was needing monitoring so again REMOVE was
called prematurely.
Daniel Stenberg (13 May 2008)
- Added test case 556 that uses curl_easy_send() and curl_easy_recv()
Daniel Stenberg (9 May 2008)
- Introducing curl_easy_send() and curl_easy_recv(). They can be used to send
and receive data over a connection previously setup with curl_easy_perform()
and its CURLOPT_CONNECT_ONLY option. The sendrecv.c example was added to
show how they can be used.
Yang Tse (9 May 2008)
- Internal time differences now use monotonic time source if available.
This also implies the removal of the winmm.lib dependency for WIN32.
Daniel Stenberg (9 May 2008)
- Stefan Krause reported a busy-looping case when using the multi interface
and doing CONNECT to a proxy. The app would then busy-loop until the proxy
completed its response.
Michal Marek (9 May 2008)
- Make Curl_write and it's callees accept a const pointer, in preparation
of tetetest's patch for curl_easy_send()
Daniel Stenberg (7 May 2008)
- Liam Healy filed the debian bug report #480044
( identifying a
segfault when using krb5 ftp, but the krb4 code had the same problem.
Yang Tse (7 May 2008)
- Christopher Palow provided the patch (edited by me) that introduces the
use of microsecond resolution keys for internal splay trees.
Daniel Stenberg (4 May 2008)
- Yuriy Sosov pointed out a configure fix for detecting c-ares when that is
built debug-enabled.
Daniel Stenberg (3 May 2008)
- Ben Van Hof filed bug report #1945240: "libcurl sometimes sends body twice
when using CURL_AUTH_ANY" (
The problem was that when libcurl rewound a stream meant for upload when it
would prepare for a second request, it could accidentally continue the
sending of the rewound data on the first request instead of on the second.
Ben also provided test case 1030 that verifies this fix.
Daniel Stenberg (3 May 2008)
- Jean-Francois Bertrand reported a libcurl crash with CURLOPT_TCP_NODELAY
since libcurl used getprotobyname() and that isn't thread-safe. We now
switched to use IPPROTO_TCP unconditionally, but perhaps the proper fix is
to detect the thread-safe version of the function and use that.
Daniel Stenberg (1 May 2008)
- Bart Whiteley provided a patch that made libcurl work properly when an app
uses the CURLOPT_OPENSOCKETFUNCTION callback to create a unix domain socket
to a http server.
Daniel Stenberg (29 Apr 2008)
- To make it easier for applications that want lots of magic stuff done on
redirections and thus cannot use CURLOPT_FOLLOWLOCATION easily, we now
introduce the new CURLINFO_REDIRECT_URL option that lets applications
extract the URL libcurl would've redirected to if it had been told to. This
then enables the application to continue to that URL as it thinks is
suitable, without having to re-implement the magic of creating the new URL
from the Location: header etc. Test 1029 verifies it.
Yang Tse (29 Apr 2008)
- Improved easy interface resolving timeout handling in c-ares enabled builds
Daniel Fandrich (28 Apr 2008)
- Added test 1028 to test an HTTP redirect to a FTP URL.
Daniel Stenberg (28 Apr 2008)
- Norbert Frese filed bug report #1951588: "Problem with curlftpfs and
libcurl" ( which seems to be an
identical report to what Denis Golovan reported in The FTP code didn't reset the
user/password pointers properly even though there might've been a new
struct/cconnection getting used.
Daniel Stenberg (26 Apr 2008)
- Reverted back to use automake 1.9.6 in the next release (from automake
1.10.1) since it *still* suffers from Solaris-related bugs. Our previous
automake 1.10 problem was reported in bug #1701360
( and this recent problem was
bug #1944825 ( I have not
personally approached the automake team about either one of these but I
figure we need a Solaris 10 guy to do it!
Yang Tse (25 Apr 2008)
- Added 'timeout' and 'delay' attributes support for the test harness
<command> subsection.
Daniel Fandrich (24 Apr 2008)
- Made --stderr able to redirect all stderr messages.
Yang Tse (23 Apr 2008)
- Improve synchronization between test harness script
and test harness servers to minimize risk of false test failures.
Daniel Fandrich (22 Apr 2008)
- Added support for running on Symbian OS.
Daniel Fandrich (18 Apr 2008)
- Added test cases 1026 and 1027 to do some rudimentary tests on the --manual
and --help options.
Michal Marek (14 Apr 2008)
- allow disabling the typechecker by defining CURL_DISABLE_TYPECHECK, as
discussed in
Daniel Stenberg (14 Apr 2008)
- Stefan Krause reported a case where the OpenSSL handshake phase wasn't
properly acknowledging the timeout values, like if you pulled the network
plug in the midst of it.
- Andre Guibert de Bruet fixed a second case of not checking the malloc()
return code in the Negotiate code.
- Sandor Feldi reported bug #1942022
( pointing out a mistake in the
lib/[68] makefiles' release-ssl-dll target.
- Brock Noland reported that curl behaved differently depending on which order
you used -i and -I.
Daniel Stenberg (12 Apr 2008)
- Andre Guibert de Bruet found and fixed a case where malloc() was called but
was not checked for a NULL return, in the Negotiate code.
Daniel Fandrich (9 Apr 2008)
- Added test cases 1024 & 1025 to test a scenario similar to the one reported
by Ben Combee where libcurl would send the wrong cookie to a redirected
server. libcurl was doing the right thing in these test cases.
Michal Marek (7 Apr 2008)
- Fix the MIT / Heimdal check for good:
Define HAVE_GSSMIT if <gssapi/{gssapi.h,gssapi_generic.h,gssapi_krb5.h}> are
available, otherwise define HAVE_GSSHEIMDAL if <gssapi.h> is available.
Only define GSS_C_NT_HOSTBASED_SERVICE to gss_nt_service_name if
GSS_C_NT_HOSTBASED_SERVICE isn't declared by the gssapi headers. This should
avoid breakage in case we wrongly recognize Heimdal as MIT again.
Daniel Stenberg (5 Apr 2008)
- Alexey Simak fixed curl_easy_reset() to reset the max redirect limit properly
- Based on the Debian bug report #474224 that complained about the FTP error
message when libcurl doesn't get a 220 back immediately on connect, I now
changed it to be more specific on what the problem is. Also worth noticing:
while the bug report contains an example where the response is:
421 There are too many connected users, please try again later
we cannot assume that the error message will always be this readable nor
that it fits within a particular boundary etc.
Daniel Fandrich (3 Apr 2008)
- Added test627 to test SFTP with CURLOPT_NOBODY
Daniel Stenberg (3 Apr 2008)
- Setting CURLOPT_NOBODY to FALSE will now switch the HTTP request method to
GET simply because previously when you set CURLOPT_NOBODY to TRUE first and
then FALSE you'd end up in a broken state where a HTTP request would do a
HEAD by still act a lot like for a GET and hang waiting for the content etc.
- Scott Barrett added support for CURLOPT_NOBODY over SFTP
Daniel Fandrich (3 Apr 2008)
- Made sure that curl_global_init is called in all the multithreaded
example programs.
Michal Marek (31 Mar 2008)
- Removed the generated ca-bundle.h file. The verbatim value of $ca and
$capath is known to configure, so it can be defined in config.h instead.
Daniel Stenberg (31 Mar 2008)
- Added CURLFORM_STREAM as a supported option to curl_formadd() to allow an
application to provide data for a multipart with the read callback. Note
that the size needs to be provided with CURLFORM_CONTENTSLENGTH when the
stream option is used. This feature is verified by the new test case
554. This feature was sponsored by Xponaut.
Daniel Fandrich (30 Mar 2008)
- Changed the makefile so the doc/examples/ programs are never built in a
normal build/install (only with the 'make check' target), so that a
build failure in the examples isn't fatal.
Version 7.18.1 (30 March 2008)
Daniel Stenberg (28 Mar 2008)
- Stephen Collyer pointed out that configure --with-libssh2 without a given
path didn't work properly.
Daniel Stenberg (27 Mar 2008)
- As found out and reported by Dan Petitt, libcurl didn't show progress/call
the progress callback for the first (potentially huge) piece of body data
sent together with the POST request headers in the initial send().
Daniel Stenberg (25 Mar 2008)
- Made setting the CURLOPT_SSL_CTX_FUNCTION option return a failure in case
libcurl wasn't built to use OpenSSL as that is a prerequisite for this
option to function!
Daniel Stenberg (22 Mar 2008)
- Fixed the problem with doing a zero byte SCP transfer, verified with test
case 617 (which was added by Daniel Fandrich 5 Mar 2008).
Daniel Fandrich (20 Mar 2008)
- Fixed a problem where curl-config --protocols could erroneously show LDAPS
support when curl didn't even have regular LDAP support. It looks like
this could happen when the --enable-ldaps configure switch is given but
configure couldn't find the LDAP headers or libraries.
Michal Marek (20 Mar 2008)
- Added --with-ca-path=DIRECTORY configure option to use an openSSL CApath by
default instead of a ca bundle. The configure script will also look for a
ca path if no ca bundle is found and no option given.
- Fixed detection of previously installed curl-ca-bundle.crt
Daniel Fandrich (18 Mar 2008)
- Added test 626 to reproduce an infinite loop when given an invalid
SFTP quote command reported by Vincent Le Normand, and fixed it.
Michal Marek (18 Mar 2008)
- Added curl_easy_getinfo typechecker.
- Added macros for curl_share_setopt and curl_multi_setopt to check at least
the correct number of arguments.
Daniel Fandrich (13 Mar 2008)
- Added tests 622-625 to test SFTP/SCP uploads. Test 625 was an attempt to
reproduce the --ftp-create-dirs problem reported by Brian Ulm, but that
seems to need a call curl_easy_reset() which this test case doesn't do.
Daniel Stenberg (13 Mar 2008)
- Brian Ulm figured out that if you did an SFTP upload with
CURLOPT_FTP_CREATE_MISSING_DIRS to create a directory, and then re-used the
handle and uploaded another file to another directory that needed to be
created, the second upload would fail. Another case of a state variable that
wasn't properly reset between requests.
- I rewrote the 100-continue code to use a single state variable instead of
the previous two ones. I think it made the logic somewhat clearer.
Daniel Stenberg (11 Mar 2008)
- Dmitry Popov filed bug report #1911069
( that identified a race
condition in the name resolver code when the DNS cache is shared between
multiple easy handles, each running in simultaneous threads that could cause
- Added a macro for curl_easy_setopt() that accepts three arguments and simply
does nothing with them, just to make sure libcurl users always use three
arguments to this function. Due to its use of ... for the third argument, it
is otherwise hard to detect abuse.
Michal Marek (11 Mar 2008)
- Added a type checking macro for curl_easy_setopt(), needs gcc-4.3 and only
works in C mode atm ( , )
Daniel Fandrich (10 Mar 2008)
- Added tests 618-621 to test SFTP/SCP transfers of more than one file
(test 620 tests the just-fixed problem reported by Brian Ulm).
Daniel Stenberg (9 Mar 2008)
- Brian Ulm reported a crash when doing a second SFTP transfer on a re-used
easy handle if curl_easy_reset() was used between them. I fixed it and Brian
verified that it cured his problem.
- Brian Ulm reported that if you first tried to download a non-existing SFTP
file and then fetched an existing one and re-used the handle, libcurl would
still report the second one as non-existing as well! I fixed it and Brian
verified that it cured his problem.
Michal Marek (6 Mar 2008)
- Fix the gssapi configure check to detect newer MIT Kerberos (patch by
Michael Calmer)
Yang Tse (6 Mar 2008)
- Fix regression on Curl_socket_ready() and Curl_poll() so that these will
again fail on select/poll errors different than EINTR.
Daniel Fandrich (5 Mar 2008)
- Fixed the test harness so it will write out zero-length data files.
- Added tests 616 and 617 to see how SFTP and SCP cope with zero-length
files, as questioned by Mike Protts. SFTP does for me but SCP doesn't
so test 617 is disabled for now.
Daniel S (4 Mar 2008)
- Mike Protts brought a patch that makes resumed transfers work with SFTP.
Daniel S (1 Mar 2008)
- Anatoli Tubman found and fixed a crash with Negotiate authentication used on
a re-used connection where both requests used Negotiate.
Guenter Knauf (26 Feb 2008)
- Kaspar Brand provided a patch to support server name indication (RFC 4366).
Daniel S (25 Feb 2008)
- Kaspar Brand made GnuTLS-built libcurl properly acknowledge the option that
forces it to prefer SSLv3.
Daniel S (23 Feb 2008)
- Sam Listopad provided a patch in feature-request #1900014 that makes libcurl (built to
use OpenSSL) support a full chain of certificates in a given PKCS12
Daniel S (22 Feb 2008)
- Georg Lippitsch made the src/Makefile.vc6 makefile use the same memory model
options as the lib/Makefile.vc6 already did.
Daniel S (21 Feb 2008)
- Zmey Petroff found a crash when libcurl accessed a NULL pointer, which
happened if you set the connection cache size to 1 and for example failed to
login to an FTP site. Bug report #1896698
Daniel S (20 Feb 2008)
- Fixed test case 405 to not fail when libcurl is built with GnuTLS
- Based on initial work done by Gautam Kachroo to address a bug, we now keep
better control at the exact state of the connection's SSL status so that we
know exactly when it has completed the SSL negotiation or not so that there
won't be accidental re-uses of connections that are wrongly believed to be
in SSL-completed-negotiate state.
- We no longer support setting the CURLOPT_URL option from inside a callback
such as the CURLOPT_SSL_CTX_FUNCTION one treat that as if it was a Location:
following. The patch that introduced this feature was done for 7.11.0, but
this code and functionality has been broken since about 7.15.4 (March 2006)
with the introduction of non-blocking OpenSSL "connects".
It was a hack to begin with and since it doesn't work and hasn't worked
correctly for a long time and nobody has even noticed, I consider it a very
suitable subject for plain removal. And so it was done.
Guenter Knauf (19 Feb 2008)
- We do no longer support SSLv2 by default since it has known flaws.
Kaspar Brand provided a patch for all supported SSL toolkits.
Daniel Fandrich (19 Feb 2008)
- Added test309 to test HTTP redirect to HTTPS URL
Daniel S (18 Feb 2008)
- We're no longer providing a very old ca-bundle in the curl tarball. You can
get a fresh one downloaded and created with 'make ca-bundle' or you can get
one from here => if you want a fresh
new one extracted from Mozilla's recent list of ca certs.
The configure option --with-ca-bundle now lets you specify what file to use
as default ca bundle for your build. If not specified, the configure script
will check a few known standard places for a global ca cert to use.
Daniel S (17 Feb 2008)
- Jerome Muffat-Meridol helped me fix Curl_done() to close the current
connection by force when it was called before the entire request is
completed, simply because we can't know if the connection really can be
re-used safely at that point.
- Based on the same debugging logic, I've also made Curl_http_done() not
return CURLE_GOT_NOTHING if called "prematurely". This should have no real
effect to anything but the code makes more sense like this.
Daniel S (15 Feb 2008)
- Made the gnutls code path not even try to get the server cert if no peer
verification is requested. Previously it would even return failure if gnutls
failed to get the server cert even though no verification was asked for.
Public server showing the problem:
- Fix my Curl_timeleft() leftover mistake in the gnutls code
- Pooyan McSporran found and fixed a flaw where you first would do a normal
http request and then you'd reuse the handle and replace the Accept: header,
as then libcurl would send two Accept: headers!
Daniel S (11 Feb 2008)
- Yang Tse pointed out a few remaining quirks from my timeout refactoring from
Feb 7 that didn't abort properly on timeouts. These are actually old
problems but now they should be fixed.
Yang Tse (10 Feb 2008)
- Bug report #1888932 ( points out
and provides test program that demonstrates that libcurl might not set error
description message for error CURLE_COULDNT_RESOLVE_HOST for Windows threaded
name resolver builds. Fixed now.
Daniel Fandrich (8 Feb 2008)
- Added key words to all SSL-using tests so they can be skipped if necessary.
Removed a few unnecessary requires SSL statements.
Daniel S (8 Feb 2008)
- Mike Hommey filed and fixed bug report #1889856
( When using the gnutls ssl
layer, cleaning-up and reinitializing curl ends up with https requests
failing with "ASN1 parser: Element was not found" errors. Obviously a
regression added in 7.16.3.
Yang Tse (8 Feb 2008)
- Improved test harness SCP/SFTP start up server verification, doing a real
connection to the sftp server, authenticating and running a simple sftp
pwd command using the test harness generated configuration and key files.
Daniel S (8 Feb 2008)
- Günter Knauf added lib/ which gets the Firefox ca bundle and
creates a suitable ca-bundle.crt file in PEM format for use with curl. The
recommended way to run it is to use 'make ca-bundle' in the build tree root.
Daniel Fandrich (7 Feb 2008)
- Added tests 1022 and 1023 to validate output of curl-config --version and
Daniel S (7 Feb 2008)
- Refactored a lot of timeout code into a few functions in an attempt to make
them all use the same (hopefully correct) logic to make it less error-prone
and easier to introduce library-wide where it should be used.
Yang Tse (6 Feb 2008)
- Fix an issue in strdup replacement function when dealing with absolutely
huge strings. Only systems without a standard strdup would be affected.
Daniel S (3 Feb 2008)
- Dmitry Kurochkin cleaned up the pipelining code and removed the need for and
use of the "is_in_pipeline" struct field.
- I wrote up and added the threaded-ssl.c example source code that shows how
to do multi-threaded downloads of HTTPS files with a libcurl that is built
with OpenSSL. It uses pthreads for the threading.
Daniel S (31 Jan 2008)
- Niklas Angebrand made the cookie support in libcurl properly deal with the
"HttpOnly" feature introduced by Microsoft and apparently also supported by
Firefox: . HttpOnly
is now supported when received from servers in HTTP headers, when written to
cookie jars and when read from existing cookie jars.
I modified test case 31 and 46 to also do some basic HttpOnly testing.
- Dmitry Kurochkin moved several struct fields from the connectdata struct to
the SingleRequest one to make pipelining better. It is a bit tricky to keep
them in the right place, to keep things related to the actual request or to
the actual connection in the right place.
Daniel S (29 Jan 2008)
- Dmitry Kurochkin fixed Curl_done() for pipelining, as it could previously
- Michal Marek fixed minor mistake in test case 553 that prevented it from
working on other IP-addresses or port numbers.
Version 7.18.0 (28 January 2008)
Daniel S (27 Jan 2008)
- Dmitry Kurochkin: In "real world" testing I found more bugs in
pipelining. Broken connection is not restored and we get into infinite
loop. It happens because of wrong is_in_pipeline values.
Daniel S (26 Jan 2008)
- Kevin Reed filed bug report #1879375
( which describes how libcurl
got lost in this scenario: proxy tunnel (or HTTPS over proxy), ask to do any
proxy authentication and the proxy replies with an auth (like NTLM) and then
closes the connection after that initial informational response.
libcurl would not properly re-initialize the connection to the proxy and
continue the auth negotiation like supposed. It does now however, as it will
now detect if one or more authentication methods were available and asked
for, and will thus retry the connection and continue from there.
- I made the progress callback get called properly during proxy CONNECT.
Daniel S (23 Jan 2008)
- Igor Franchuk pointed out that CURLOPT_COOKIELIST set to "ALL" leaked
memory, and so did "SESS". Fixed now.
Yang Tse (22 Jan 2008)
- Check poll.h at configuration time, and use it when sys/poll.h unavailable
Daniel S (22 Jan 2008)
- Dmitry Kurochkin removed the cancelled state for pipelining, as we agreed
that it is bad anyway. Starting now, removing a handle that is in used in a
pipeline will break the pipeline - it'll be set back up again but still...
Yang Tse (21 Jan 2008)
- Disable ldap support for cygwin builds, since it breaks whole build process.
Fixing it will affect other platforms, so it is postponed for another release.
Daniel S (18 Jan 2008)
- Lau Hang Kin found and fixed a problem with the multi interface when doing
CONNECT over a proxy. curl_multi_fdset() didn't report back the socket
properly during that state, due to a missing case in the switch in the
multi_getsock() function.
Yang Tse (17 Jan 2008)
- Don't abort tests 518 and 537 when unable to raise the open-file soft limit.
Daniel S (16 Jan 2008)
- Nathan Coulter's patch that makes respect the PATH when figuring
out what valgrind to run.
Yang Tse (16 Jan 2008)
- Improved handling of out of memory in the command line tool that afected
data url encoded HTTP POSTs when reading it from a file.
Daniel S (16 Jan 2008)
- Dmitry Kurochkin worked a lot on improving the HTTP Pipelining support that
previously had a number of flaws, perhaps most notably when an application
fired up N transfers at once as then they wouldn't pipeline at all that
nicely as anyone would think... Test case 530 was also updated to take the
improved functionality into account.
- Calls to Curl_failf() are not supposed to provide a trailing newline as the
function itself adds that. Fixed on 50 or something strings!
Daniel S (15 Jan 2008)
- I made the torture test on test 530 go through. This was actually due to
silly code left from when we switched to let the multi handle "hold" the dns
cache when using the multi interface... Of course this only triggered when a
certain function call returned error at the correct moment.

- Joe Malicki filed bug report #1871269
( and we could fix his hang-
problem that occurred when doing a large HTTP POST request with the
response-body read from a callback.
Daniel S (12 Jan 2008)
- I re-arranged the curl --help output. All the options are now sorted on
their long option names and all descriptions are one-liners.
- Eric Landes provided the patch (edited by me) that introduces the
--keepalive-time to curl to set the keepalive probe interval. I also took
the opportunity to rename the recently added no-keep-alive option to
no-keepalive to keep a consistent naming and to avoid getting two dashes in
these option names. Eric also provided an update to the man page for the new
Daniel S (11 Jan 2008)
- Daniel Egger made CURLOPT_RANGE work on file:// URLs the very same way it
already worked for FTP:// URLs.
- I made the curl tool switch from using CURLOPT_IOCTLFUNCTION to now use the
spanking new CURLOPT_SEEKFUNCTION simply to take advantage of the improved
performance for the upload resume cases where you want to upload the last
few bytes of a very large file. To implement this decently, I had to switch
the client code for uploading from fopen()/fread() to plain open()/read() so
that we can use lseek() to do >32bit seeks (as fseek() doesn't allow that)
on systems that offer support for that.
Daniel S (10 Jan 2008)
- Michal Marek made curl-config --libs not include /usr/lib64 in the output
(it already before skipped /usr/lib). /usr/lib64 is the default library
directory on many 64bit systems and it's unlikely that anyone would use the
path privately on systems where it's not.
- Georg Lippitsch brought CURLOPT_SEEKFUNCTION and CURLOPT_SEEKDATA to allow
libcurl to seek in a given input stream. This is particularly important when
doing upload resumes when there's already a huge part of the file present
remotely. Before, and still if this callback isn't used, libcurl will read
and through away the entire file up to the point to where the resuming
begins (which of course can be a slow opereration depending on file size,
I/O bandwidth and more). This new function will also be preferred to get
used instead of the CURLOPT_IOCTLFUNCTION for seeking back in a stream when
doing multi-stage HTTP auth with POST/PUT.
- Nikitinskit Dmitriy filed bug report #1868255
( with a patch. It identifies
and fixes a problem with parsing WWW-Authenticate: headers with additional
spaces in the line that the parser wasn't written to deal with.
Daniel S (8 Jan 2008)
- Introducing curl_easy_pause() and new magic return codes for both the read
and the write callbacks that now can make a connection's reading and/or
writing get paused.
Daniel S (6 Jan 2008)
- Jeff Johnson filed bug report #1863171
( where he pointed out that
libcurl's date parser didn't accept a +1300 time zone which actually is used
fairly often (like New Zealand's Dailight Savings Time), so I modified the
parser to now accept up to and including -1400 to +1400.
Daniel S (5 Jan 2008)
- Based on further discussion on curl-library, I reverted yesterday's SOCKS5
code to instead introduce support for a new proxy type called
CURLPROXY_SOCKS5_HOSTNAME that is used to send the host name to the proxy
instead of IP address and there's thus no longer any need for a new
curl_easy_setopt() option.
The default SOCKS5 proxy is again back to sending the IP address to the
proxy. The new curl command line option for enabling sending host name to a
SOCKS5 proxy is now --socks5-hostname.
Daniel S (4 Jan 2008)
- Based on Maxim Perenesenko's patch, we now do SOCKS5 operations and let the
proxy do the host name resolving and only if --socks5ip (or
CURLOPT_SOCKS5_RESOLVE_LOCAL) is used we resolve the host name locally and
pass on the IP address only to the proxy.
Yang Tse (3 Jan 2008)
- Modified test harness to allow SCP, SFTP and SOCKS4 tests to run with
OpenSSH 2.9.9, SunSSH 1.0 or later versions. SOCKS5 tests need OpenSSH
3.7, SunSSH 1.0 or later.
Daniel S (2 Jan 2008)
- I fixed two cases of missing return code checks when handling chunked
decoding where a write error (or abort return from a callback) didn't stop
libcurl's processing.
- I removed the socklen_t use from the public curl/curl.h header and instead
made it an unsigned int. The type was only used in the curl_sockaddr struct
definition (only used by the curl_opensocket_callback). On all platforms I
could find information about, socklen_t is 32 unsigned bits large so I don't
think this will break the API or ABI. The main reason for this change is of
course for all the platforms that don't have a socklen_t definition in their
headers to build fine again. Providing our own configure magic and custom
definition of socklen_t on those systems proved to work but was a lot of
cruft, code and extra magic needed - when this very small change of type
seems harmless and still solves the missing socklen_t problem.
- Richard Atterer brought a patch that added support for SOCKS4a proxies,
which is an inofficial PROXY4 variant that sends the hostname to the proxy
instead of the resolved address (which is already supported by SOCKS5).
--socks4a is the curl command line option for it and CURLOPT_PROXYTYPE can
now be set to CURLPROXY_SOCKS4A as well.
Daniel S (1 Jan 2008)
- Mohun Biswas pointed out that --libcurl generated a source code with an int
function but without a return statement. While fixing that, I also took care
about adding some better comments for the generated code.
Daniel S (27 Dec 2007)
- Dmitry Kurochkin mentioned a flaw
( in detect_proxy() which
failed to set the bits.proxy variable properly when an environment variable
told libcurl to use a http proxy.
Daniel S (26 Dec 2007)
- In an attempt to repeat the problem in bug report #1850730
( I wrote up test case 552. The
test is doing a 70K POST with a read callback and an ioctl callback over a
proxy requiring Digest auth. The test case code is more or less identical to
the test recipe code provided by Spacen Jasset (who submitted the bug
Daniel S (25 Dec 2007)
- Gary Maxwell filed bug report #1856628
( and provided a fix for the
(small) memory leak in the SSL session ID caching code. It happened when a
previous entry in the cache was re-used.

- Ensure that nroff doesn't put anything but ASCII characters into the
--manual text.
Yang Tse (18 Dec 2007)
- MSVC 9.0 (VS2008) does not support Windows build targets prior to WinXP,
and makes wrong asumptions of build target when it isn't specified. So,
if no build target has been defined we will target WinXP when building
curl/libcurl with MSVC 9.0 (VS2008).
- ( reported and fixed
a file truncation problem on Windows build targets triggered when retrying
a download with curl.
Daniel S (17 Dec 2007)
- Mateusz Loskot pointed out that MSVC 9.0 (VS2008) has the pollfd struct and
defines in winsock2.h somehow differently than previous versions and that
curl 7.17.1 would fail to compile out of the box.
Daniel S (13 Dec 2007)
- David Wright filed bug report #1849764
( with an included fix. He
identified a problem for re-used connections that previously had sent
Expect: 100-continue and in some situations the subsequent POST (that didn't
use Expect:) still had the internal flag set for its use. David's fix (that
makes the setting of the flag in every single request unconditionally) is
fine and is now used!
Daniel S (12 Dec 2007)
- Gilles Blanc made the curl tool enable SO_KEEPALIVE for the connections and
added the --no-keep-alive option that can disable that on demand.
Daniel S (9 Dec 2007)
- Andrew Moise filed bug report #1847501
( and pointed out a memcpy()
that should be memmove() in the convert_lineends() function.
Daniel S (8 Dec 2007)
- Renamed all internal static functions that had Curl_ prefixes to no longer
have them. The Curl_ prefix is exclusively used for library internal global
symbols. Static functions can be named anything, except for using Curl_ or
curl_ prefixes. This is for consistency and for easier maintainance and
- Cleaned up and reformatted the TODO document to look like the FAQ and
CONTRIBUTE, which makes nicer web pages
- Added test cases 549 and 550 that test CURLOPT_PROXY_TRANSFER_MODE.
- Added keywords on a bunch of test cases
