Changelog
Version 7.19.4 (3 March 2009)
Daniel Stenberg (3 Mar 2009)
- David Kierznowski notified us about a security flaw
(http://curl.haxx.se/docs/adv_20090303.html 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
elsewhere.
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
CURLINFO_CONTENT_LENGTH_DOWNLOAD and CURLINFO_CONTENT_LENGTH_UPLOAD return
-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
data!
Patrick Monnerat (18 Feb 2009)
- FTP downloads (i.e.: RETR) ending with code 550 now return error
CURLE_REMOTE_FILE_NOT_FOUND instead of CURLE_FTP_COULDNT_RETR_FILE.
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
CURLFTP_CREATE_DIR and CURLFTP_CREATE_DIR_RETRY.
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
(http://curl.haxx.se/bug/view.cgi?id=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
CURLOPT_NOBODY set true.
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
(http://curl.haxx.se/bug/view.cgi?id=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
reporting.
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:
CURLOPT_SOCKS5_GSSAPI_SERVICE and CURLOPT_SOCKS5_GSSAPI_NEC to allow 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
these.
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: http://tools.ietf.org/html/rfc5077
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
(http://curl.haxx.se/bug/view.cgi?id=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
locale.
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
originally-designed):
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
transfer...
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
appropriate.
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 (http://curl.haxx.se/bug/view.cgi?id=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
makefiles.
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
CURLOPT_FTP_FILEMETHOD and CURLOPT_SSL_SESSIONID_CACHE
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 http://curl.haxx.se/bug/view.cgi?id=2479030 pointing
out that 'reconf' didn't properly point out the m4 subdirectory when running
aclocal.
Daniel Stenberg (29 Dec 2008)
- Phil Lisiecki filed bug report #2413067
(http://curl.haxx.se/bug/view.cgi?id=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
--disable-verbose".
- 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
(http://curl.haxx.se/bug/view.cgi?id=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"
(http://curl.haxx.se/bug/view.cgi?id=2416182) 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
(http://curl.haxx.se/bug/view.cgi?id=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
(http://curl.haxx.se/bug/view.cgi?id=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.
(http://curl.haxx.se/bug/view.cgi?id=2382219)
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
method.
- 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 runtests.pl -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 (http://curl.haxx.se/bug/view.cgi?id=2284386)
- 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
paused.
Daniel Stenberg (11 Nov 2008)
- Rainer Canavan filed bug #2255627
(http://curl.haxx.se/bug/view.cgi?id=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 (http://curl.haxx.se/bug/view.cgi?id=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 (http://curl.haxx.se/bug/view.cgi?id=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 (http://curl.haxx.se/bug/view.cgi?id=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
both.
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
637.
Daniel Fandrich (17 Oct 2008)
- Fixed a compile error reported by Albert Chin on AIX and IRIX when using
GTLS.
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
(http://curl.haxx.se/bug/view.cgi?id=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
(http://curl.haxx.se/bug/view.cgi?id=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
(http://curl.haxx.se/bug/view.cgi?id=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
(http://curl.haxx.se/bug/view.cgi?id=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
millisecond.
- 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.

- 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.
runtests.pl 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
--disable-proxy.
Daniel Fandrich (29 Sep 2008)
- Moved all signal-based name resolution timeout handling into a single new
Curl_resolv_timeout function to reduce coupling.
Daniel Stenberg (29 Sep 2008)
- Ian Lynagh provided a patch that now makes CURLOPT_RANGE work fine for SFTP
downloads!
- Maxim Ivanov filed bug report #2107803
(http://curl.haxx.se/bug/view.cgi?id=2107803) "no CURLINFO_REDIRECT_URL in
multi mode" together with a patch that fixed the problem.
Daniel Stenberg (25 Sep 2008)
- Emanuele Bovisio submitted bug report #2126435. We fixed the HTTP Digest
auth code to not behave badly when getting a blank realm with
realm="". http://curl.haxx.se/bug/view.cgi?id=2126435
Daniel Fandrich (23 Sep 2008)
- 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.
- Rob Crittenden brought a patch to "add some locking for thread-safety to NSS
implementation".
Daniel Stenberg (22 Sep 2008)
- Made the SOCKS code use the new Curl_read_plain() function to fix the bug
Markus Moeller reported: http://curl.haxx.se/mail/archive-2008-09/0016.html
- 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" (http://curl.haxx.se/bug/view.cgi?id=2107377) 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.
Daniel Fandrich (22 Sep 2008)
- Fixed test 539 to handle an out of memory condition that shows up now
that memdebug.h is included in the test programs.
Yang Tse (20 Sep 2008)
- Fix regression in configure script which affected OpenSSL builds on MSYS.
Yang Tse (19 Sep 2008)
- 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
page.
- 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
OpenSSL.
This feature was sponsored by networking4all.com - 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 curl-config.in
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.
