-Change log for Varnish 1.0.4
-
-Changes between 1.0.3 and 1.0.4
-
-varnishd
-
- • The request workflow has been redesigned to simplify request processing and
- eliminate code duplication. All codepaths which need to speak HTTP now
- share a single implementation of the protocol. Some new VCL hooks have been
- added, though they aren't much use yet. The only real user-visible change
- should be that Varnish now handles persistent backend connections correctly
- (see ticket #56).
-
- • Support for multiple listen addresses has been added.
-
- • An "include" facility has been added to VCL, allowing VCL code to pull in
- code fragments from multiple files.
-
- • Multiple definitions of the same VCL function are now concatenated into one
- in the order in which they appear in the source. This simplifies the
- mechanism for falling back to the built-in default for cases which aren't
- handled in custom code, and facilitates modularization.
-
- • The code used to format management command arguments before passing them on
- to the child process would underestimate the amount of space needed to hold
- each argument once quotes and special characters were properly escaped,
- resulting in a buffer overflow. This has been corrected.
-
- • The VCL compiler has been overhauled. Several memory leaks have been
- plugged, and error detection and reporting has been improved throughout.
- Parts of the compiler have been refactored to simplify future extension of
- the language.
-
- • A bug in the VCL compiler which resulted in incorrect parsing of the
- decrement (-=) operator has been fixed.
-
- • A new -C command-line option has been added which causes varnishd to
- compile the VCL code (either from a file specified with -f or the built-in
- default), print the resulting C code and exit.
-
- • When processing a backend response using chunked encoding, if a chunk
- header crosses a read buffer boundary, read additional bytes from the
- backend connection until the chunk header is complete.
-
- • A new ping_interval run-time parameter controls how often the management
- process checks that the worker process is alive.
-
- • A bug which would cause the worker process to dereference a NULL pointer
- and crash if the backend did not respond has been fixed.
-
- • In some cases, such as when they are used by AJAX applications to
- circumvent Internet Explorer's over-eager disk cache, it may be desirable
- to cache POST requests. However, the code path responsible for delivering
- objects from cache would only transmit the response body when replying to a
- GET request. This has been extended to also apply to POST.
-
- This should be revisited at a later date to allow VCL code to control
- whether the body is delivered.
-
- • Varnish now respects Cache-control: s-maxage, and prefers it to
- Cache-control: max-age if both are present.
-
- This should be revisited at a later date to allow VCL code to control which
- headers are used and how they are interpreted.
-
- • When loading a new VCL script, the management process will now load the
- compiled object to verify that it links correctly before instructing the
- worker process to load it.
-
- • A new -P command-line options has been added which causes varnishd to
- create a PID file.
-
- • The sendfile_threshold run-time parameter's default value has been set to
- infinity after a variety of sendfile()-related bugs were discovered on
- several platforms.
-
-varnishlog
-
- • When grouping log entries by request, varnishlog attempts to collapse the
- log entry for a call to a VCL function with the log entry for the
- corresponding return from VCL. When two VCL calls were made in succession,
- varnishlog would incorrectly omit the newline between the two calls (see
- ticket #95).
-
- • New -D and -P command-line options have been added to daemonize and create
- a pidfile, respectively.
-
-varnishncsa
-
- • The formatting callback has been largely rewritten for clarity, robustness
- and efficiency.
-
- If a request included a Host: header, construct and output an absolute URL.
- This makes varnishncsa output from servers which handle multiple virtual
- hosts far more useful.
-
-Documentation
-
- • The documentation—especially the VCL documentation—has been greatly
- extended and improved.
-
-Build system
-
- • The name and location of the curses or ncurses library is now correctly
- detected by the configure script instead of being hardcoded into affected
- Makefiles. This allows Varnish to build correctly on a wider range of
- platforms.
-
- • Compatibility shims for clock_gettime() are now correctly applied where
- needed, allowing Varnish to build on MacOS X.
-
- • The autogen.sh script will now correctly detect and warn about automake
- versions which are known not to work correctly.
