- Announcing Privoxy v.3.0.20 beta
+ Announcing Privoxy 3.0.25 beta
--------------------------------------------------------------------
-This is a beta release that introduces some new features and fixes a number of bugs, some of which are reasonably significant. One new feature (tolerate-pipelining) is enabled by default. See below for details.
-
+Privoxy 3.0.25 beta introduces client-specific tags and includes
+a couple of minor improvements. It will be followed by a stable
+release in the near future.
--------------------------------------------------------------------
ChangeLog for Privoxy
--------------------------------------------------------------------
-*** Version 3.0.20 Beta ***
-
-- Bug fixes:
- - Client sockets are now properly shutdown and drained before being
- closed. This fixes page truncation issues with clients that aggressively
- pipeline data on platforms that otherwise discard already written data.
- The issue mainly affected Opera users and was initially reported
- by Kevin in #3464439, szotsaki provided additional information to track
- down the cause.
- - Fix latency calculation for shared connections (disabled by default).
- It was broken since their introduction in 2009. The calculated latency
- for most connections would be 0 in which case the timeout detection
- failed to account for the real latency.
- - Reject URLs with invalid port. Previously they were parsed incorrectly and
- characters between the port number and the first slash were silently
- dropped as shown by curl test 187.
- - The default-server-timeout and socket-timeout directives accept 0 as
- valid value.
- - Fix a race condition on Windows that could cause Privoxy to become
- unresponsive after toggling it on or off through the taskbar icon.
- Reported by Tim H. in #3525694.
- - Fix the compilation on Windows when configured without IPv6 support.
- - Fix an assertion that could cause debug builds to abort() in case of
- socks5 connection failures with "debug 2" enabled.
- - Fix an assertion that could cause debug builds to abort() if a filter
- contained nul bytes in the replacement text.
-
-- General improvements:
- - Significantly improved keep-alive support for both client and server
- connections.
- - New debug log level 65536 which logs all actions that were applied to
- the request.
- - New directive client-header-order to forward client headers in a
- different order than the one in which they arrived.
- - New directive tolerate-pipelining to allow client-side pipelining.
- If enabled (3.0.20 beta enables it by default), Privoxy will keep
- pipelined client requests around to deal with them once the current
- request has been served.
- - New --config-test option to let Privoxy exit after checking whether or not
- the configuration seems valid. The limitations noted in TODO #22 and #23
- still apply. Based on a patch by Ramkumar Chinchani.
- - New limit-cookie-lifetime{} action to let cookies expire before the end
- of the session. Suggested by Rick Sykes in #1049575.
- - Increase the hard-coded maximum number of actions and filter files from
- 10 to 30 (each). It doesn't significantly affect Privoxy's memory usage
- and recompiling wasn't an option for all Privoxy users that reached the
- limit.
- - Add support for chunk-encoded client request bodies. Previously
- chunk-encoded request bodies weren't guaranteed to be forwarded correctly,
- so this can also be considered a bug fix although chunk-encoded request
- bodies aren't commonly used in the real world.
- - Add support for Tor's optimistic-data SOCKS extension, which can reduce the
- latency for requests on newly created connections. Currently only the
- headers are sent optimistically and only if the client request has already
- been read completely which rules out requests with large bodies.
- - After preventing the client from pipelining, don't signal keep-alive
- intentions. When looking at the response headers alone, it previously
- wasn't obvious from the client's perspective that no additional responses
- should be expected.
- - Stop considering client sockets tainted after receving a request with body.
- It hasn't been necessary for a while now and unnecessarily causes test
- failures when using curl's test suite.
- - Allow HTTP/1.0 clients to signal interest in keep-alive through the
- Proxy-Connection header. While such client are rare in the real world, it
- doesn't hurt and couple of curl tests rely on it.
- - Only remove duplicated Content-Type headers when filters are enabled.
- If they are not it doesn't cause ill effects and the user might not want it.
- Downgrade the removal message to LOG_LEVEL_HEADER to clarify that it's not
- an error in Privoxy and is unlikely to cause any problems in general.
- Anonymously reported in #3599335.
- - Set the socket option SO_LINGER for the client socket.
- - Move several variable declarations to the beginning of their code block.
- It's required when compiling with gcc 2.95 which is still used on some
- platforms. Initial patch submitted by Simon South in #3564815.
- - Optionally try to sanity-check strptime() results before trusting them.
- Broken strptime() implementations have caused problems in the past and
- the most recent offender seems to be FreeBSD's libc (standards/173421).
- - When filtering is enabled, let Range headers pass if the range starts at
- the beginning. This should work around (or at least reduce ) the video
- playback issues with various Apple clients as reported by Duc in #3426305.
- - Do not confuse a client hanging up with a connection time out. If a client
- closes its side of the connection without sending a request line, do not
- send the CLIENT_CONNECTION_TIMEOUT_RESPONSE, but report the condition
- properly.
- - Allow closing curly braces as part of action values as long as they are
- escaped.
- - On Windows, the logfile is now written before showing the GUI error
- message which blocks until the user acknowledges it.
- Reported by Adriaan in #3593603.
- - Remove an unreasonable parameter limit in the CGI interface. The new
- parameter limit depends on the memory available and is currently unlikely
- to be reachable, due to other limits in both Privoxy and common clients.
- Reported by Andrew on ijbswa-users@.
- - Decrease the chances of parse failures after requests with unsupported
- methods were sent to the CGI interface.
-
-*** Version 3.0.19 Stable ***
-
- Bug fixes:
- - Prevent a segmentation fault when de-chunking buffered content.
- It could be triggered by malicious web servers if Privoxy was
- configured to filter the content and running on a platform
- where SIZE_T_MAX isn't larger than UINT_MAX, which probably
- includes most 32-bit systems. On those platforms, all Privoxy
- versions before 3.0.19 appear to be affected.
- To be on the safe side, this bug should be presumed to allow
- code execution as proving that it doesn't seems unrealistic.
- - Do not expect a response from the SOCKS4/4A server until it
- got something to respond to. This regression was introduced
- in 3.0.18 and prevented the SOCKS4/4A negotiation from working.
- Reported by qqqqqw in #3459781.
+ - Always use the current toggle state for new requests.
+ Previously new requests on reused connections inherited
+ the toggle state from the previous request even though
+ the toggle state could have changed.
+ Reported by Robert Klemme.
+ - Fixed two buffer-overflows in the (deprecated) static
+ pcre code. These bugs are not considered security issues
+ as the input is trusted.
+ Found with afl-fuzz and ASAN.
- General improvements:
- - Fix an off-by-one in an error message about connect failures.
- - Use a GNUMakefile variable for the webserver root directory and
- update the path. Sourceforge changed it which broke various
- web-related targets.
- - Update the CODE_STATUS description.
+ - Added support for client-specific tags which allow Privoxy
+ admins to pre-define tags that are set for all requests from
+ clients that previously opted in through the CGI interface.
+ They are useful in multi-user setups where admins may
+ want to allow users to disable certain actions and filters
+ for themselves without affecting others.
+ In single-user setups they are useful to allow more fine-grained
+ toggling. For example to disable request blocking while still
+ crunching cookies, or to disable experimental filters only.
+ This is an experimental feature, the syntax and behaviour may
+ change in future versions.
+ Sponsored by Robert Klemme.
+ - Dynamic filters and taggers now support a $listen-address variable
+ which contains the address the request came in on.
+ For external filters the variable is called $PRIVOXY_LISTEN_ADDRESS.
+ Original patch contributed by pursievro.
+ - Add client-header-tagger 'listen-address'.
+ - Include the listen-address in the log message when logging new requests.
+ Patch contributed by pursievro.
+ - Turn invalid max-client-connections values into fatal errors.
+ - The show-status page now shows whether or not dates before 1970
+ and after 2038 are expected to be handled properly.
+ This is mainly useful for Privoxy-Regression-Test but could
+ also come handy when dealing with time-related support requests.
+ - On Mac OS X the thread id in log messages are more likely to
+ be unique now.
+ - When complaining about missing filters, the filter type is logged
+ as well.
+ - A couple of harmless coverity warnings were silenced
+ (CID #161202, CID #161203, CID #161211).
+
+- Action file improvements:
+ - Filtering is disabled for Range requests to let download resumption
+ and Windows updates work with the default configuration.
+ - Unblock ".ardmediathek.de/".
+ Reported by ThTomate in #932.
+
+- Documentation improvements:
+ - Add FAQ entry for crashes caused by memory limits.
+ - Remove obsolete FAQ entry about a bug in PHP 4.2.3.
+ - Mention the new mailing lists were appropriate.
+ As the archives have not been migrated, continue to
+ mention the archives at SF in the contacting section
+ for now.
+ - Note that the templates should be adjusted if Privoxy is
+ running as intercepting proxy without getting all requests.
+ - A bunch of links were converted to https://.
+ - Rephrase onion service paragraph to make it more obvious
+ that Tor is involved and that the whole website (and not
+ just the homepage) is available as onion service.
+ - Streamline the "More information" section on the homepage further
+ by additionally ditching the link to the 'See also' section
+ of the user manual. The section contains mostly links that are
+ directly reachable from the homepage already and the rest is
+ not significant enough to get a link from the homepage.
+ - Change the add-header{} example to set the DNT header
+ and use a complete section to make copy and pasting
+ more convenient.
+ Add a comment to make it obvious that adding the
+ header is not recommended for obvious reasons.
+ Using the DNT header as example was suggested by
+ Leo Wzukw.
+ - Streamline the support-and-service template
+ Instead of linking to the various support trackers
+ (whose URLs hopefully change soon), link to the
+ contact section of the user manual to increase the
+ chances that users actually read it.
+ - Add a FAQ entry for tainted sockets.
+ - More sections in the documentation have stable URLs now.
+ - FAQ: Explain why 'ping config.privoxy.org' is not expected
+ to reach a local Privoxy installation.
+ - Note that donations done through Zwiebelfreunde e.V. currently
+ can't be checked automatically.
+ - Updated section regarding starting Privoxy under OS X.
+ - Use dedicated start instructions for FreeBSD and ElectroBSD.
+ - Removed release instructions for AIX. They haven't been working
+ for years and unsurprisingly nobody seems to care.
+ - Removed obsolete reference to the solaris-dist target.
+ - Updated the release instructions for FreeBSD.
+ - Removed unfinished release instructions for Amiga OS and HP-UX 11.
+ - Added a pointer to the Cygwin Time Machine for getting the last release of
+ Cygwin version 1.5 to use for building Privoxy on Windows.
+ - Various typos have been fixed.
+
+- Infrastructure improvements:
+ - The website is no longer hosted at SourceForge and
+ can be reached through https now.
+ - The mailing lists at SourceForge have been deprecated,
+ you can subscribe to the new ones at: https://lists.privoxy.org/
+ - Migrating the remaining services from SourceForge is
+ work in progress (TODO list item #53).
+
+- Build system improvements:
+ - Add configure argument to optimistically redefine FD_SETSIZE
+ with the intent to change the maximum number of client
+ connections Privoxy can handle. Only works with some libcs.
+ Sponsored by Robert Klemme.
+ - Let the tarball-dist target skip files in ".git".
+ - Let the tarball-dist target work in cwds other than current.
+ - Make the 'clean' target faster when run from a git repository.
+ - Include tools in the generic distribution.
+ - Let the gen-dist target work in cwds other than current.
+ - Sort find output that is used for distribution tarballs
+ to get reproducible results.
+ - Don't add '-src' to the name of the tar ball generated by the
+ gen-dist target. The package isn't a source distribution but a
+ binary package.
+ While at it, use a variable for the name to reduce the chances
+ that the various references get out of sync and fix the gen-upload
+ target which was looking in the wrong directory.
+ - Add regression-tests.action to the files that are distributed.
+ - The gen-dist target which was broken since 2002 (r1.92) has been fixed.
+ - Remove genclspec.sh which has been obsolete since 2009.
+ - Remove obsolete reference to Redhat spec file.
+ - Remove the obsolete announce target which has been commented out years ago.
+ - Let rsync skip files if the checksums match.
+
+- Privoxy-Regression-Test:
+ - Add a "Default level offset" directive which can be used to
+ change the default level by a given value.
+ This directive affects all tests located after it until the end
+ of the file or a another "Default level offset" directive is reached.
+ The purpose of this directive is to make it more convenient to skip
+ similar tests in a given file without having to remove or disable
+ the tests completely.
+ - Let test level 17 depend on FEATURE_64_BIT_TIME_T
+ instead of FEATURE_PTHREAD which has no direct connection
+ to the time_t size.
+ - Fix indentation in perldoc examples.
+ - Don't overlook directives in the first line of the action file.
+ - Bump version to 0.7.
+ - Fix detection of the Privoxy version now that https://
+ is used for the website.
