ChangeLog for Privoxy
--------------------------------------------------------------------
-*** Version 3.0.20 Beta ***
+*** Version 3.0.24 stable ***
+
+- Security fixes (denial of service):
+ - Prevent invalid reads in case of corrupt chunk-encoded content.
+ CVE-2016-1982. Bug discovered with afl-fuzz and AddressSanitizer.
+ - Remove empty Host headers in client requests.
+ Previously they would result in invalid reads. CVE-2016-1983.
+ Bug discovered with afl-fuzz and AddressSanitizer.
+
+- Bug fixes:
+ - When using socks5t, send the request body optimistically as well.
+ Previously the request body wasn't guaranteed to be sent at all
+ and the error message incorrectly blamed the server.
+ Fixes #1686 reported by Peter Müller and G4JC.
+ - Fixed buffer scaling in execute_external_filter() that could lead
+ to crashes. Submitted by Yang Xia in #892.
+ - Fixed crashes when executing external filters on platforms like
+ Mac OS X. Reported by Jonathan McKenzie on ijbswa-users@.
+ - Properly parse ACL directives with ports when compiled with HAVE_RFC2553.
+ Previously the port wasn't removed from the host and in case of
+ 'permit-access 127.0.0.1 example.org:80' Privoxy would try (and fail)
+ to resolve "example.org:80" instead of example.org.
+ Reported by Pak Chan on ijbswa-users@.
+ - Check requests more carefully before serving them forcefully
+ when blocks aren't enforced. Privoxy always adds the force token
+ at the beginning of the path, but would previously accept it anywhere
+ in the request line. This could result in requests being served that
+ should be blocked. For example in case of pages that were loaded with
+ force and contained JavaScript to create additionally requests that
+ embed the origin URL (thus inheriting the force prefix).
+ The bug is not considered a security issue and the fix does not make
+ it harder for remote sites to intentionally circumvent blocks if
+ Privoxy isn't configured to enforce them.
+ Fixes #1695 reported by Korda.
+ - Normalize the request line in intercepted requests to make rewriting
+ the destination more convenient. Previously rewrites for intercepted
+ requests were expected to fail unless $hostport was being used, but
+ they failed "the wrong way" and would result in an out-of-memory
+ message (vanilla host patterns) or a crash (extended host patterns).
+ Reported by "Guybrush Threepwood" in #1694.
+ - Enable socket lingering for the correct socket.
+ Previously it was repeatedly enabled for the listen socket
+ instead of for the accepted socket. The bug was found by
+ code inspection and did not cause any (reported) issues.
+ - Detect and reject parameters for parameter-less actions.
+ Previously they were silently ignored.
+ - Fixed invalid reads in internal and outdated pcre code.
+ Found with afl-fuzz and AddressSanitizer.
+ - Prevent invalid read when loading invalid action files.
+ Found with afl-fuzz and AddressSanitizer.
+ - Windows build: Use the correct function to close the event handle.
+ It's unclear if this bug had a negative impact on Privoxy's behaviour.
+ Reported by Jarry Xu in #891.
+ - In case of invalid forward-socks5(t) directives, use the
+ correct directive name in the error messages. Previously they
+ referred to forward-socks4t failures.
+ Reported by Joel Verhagen in #889.
+
+- General improvements:
+ - Set NO_DELAY flag for the accepting socket. This significantly reduces
+ the latency if the operating system is not configured to set the flag
+ by default. Reported by Johan Sintorn in #894.
+ - Allow to build with mingw x86_64. Submitted by Rustam Abdullaev in #135.
+ - Introduce the new forwarding type 'forward-webserver'.
+ Currently it is only supported by the forward-override{} action and
+ there's no config directive with the same name. The forwarding type
+ is similar to 'forward', but the request line only contains the path
+ instead of the complete URL.
+ - The CGI editor no longer treats 'standard.action' special.
+ Nowadays the official "standards" are part of default.action
+ and there's no obvious reason to disallow editing them through
+ the cgi editor anyway (if the user decided that the lack of
+ authentication isn't an issue in her environment).
+ - Improved error messages when rejecting intercepted requests
+ with unknown destination.
+ - A couple of log messages now include the number of active threads.
+ - Removed non-standard Proxy-Agent headers in HTTP snipplets
+ to make testing more convenient.
+ - Include the error code for pcre errors Privoxy does not recognize.
+ - Config directives with numerical arguments are checked more carefully.
+ - Privoxy's malloc() wrapper has been changed to prevent zero-size
+ allocations which should only occur as the result of bugs.
+ - Various cosmetic changes.
+
+- Action file improvements:
+ - Unblock ".deutschlandradiokultur.de/".
+ Reported by u302320 in #924.
+ - Add two fast-redirect exceptions for "yandex.ru".
+ - Disable filter{banners-by-size} for ".plasmaservice.de/".
+ - Unblock "klikki.fi/adv/".
+ - Block requests for "resources.infolinks.com/".
+ Reported by "Black Rider" on ijbswa-users@.
+ - Block a bunch of criteo domains.
+ Reported by Black Rider.
+ - Block "abs.proxistore.com/abe/".
+ Reported by Black Rider.
+ - Disable filter{banners-by-size} for ".black-mosquito.org/".
+ - Disable fast-redirects for "disqus.com/".
+
+- Documentation improvements:
+ - FAQ: Explicitly point fingers at ASUS as an example of a
+ company that has been reported to force malware based on
+ Privoxy upon its customers.
+ - Correctly document the action type for a bunch of "multi-value"
+ actions that were incorrectly documented to be "parameterized".
+ Reported by Gregory Seidman on ijbswa-users@.
+ - Fixed the documented type of the forward-override{} action
+ which is obviously 'parameterized'.
+
+- Website improvements:
+ - Users who don't trust binaries served by SourceForge
+ can get them from a mirror. Migrating away from SourceForge
+ is planned for 2016 (TODO list item #53).
+ - The website is now available as onion service
+ (http://jvauzb4sb3bwlsnc.onion/).
+
+*** Version 3.0.23 stable ***
+
+- Bug fixes:
+ - Fixed a DoS issue in case of client requests with incorrect
+ chunk-encoded body. When compiled with assertions enabled
+ (the default) they could previously cause Privoxy to abort().
+ Reported by Matthew Daley. CVE-2015-1380.
+ - Fixed multiple segmentation faults and memory leaks in the
+ pcrs code. This fix also increases the chances that an invalid
+ pcrs command is rejected as such. Previously some invalid commands
+ would be loaded without error. Note that Privoxy's pcrs sources
+ (action and filter files) are considered trustworthy input and
+ should not be writable by untrusted third-parties. CVE-2015-1381.
+ - Fixed an 'invalid read' bug which could at least theoretically
+ cause Privoxy to crash. So far, no crashes have been observed.
+ CVE-2015-1382.
+ - Compiles with --disable-force again. Reported by Kai Raven.
+ - Client requests with body that can't be delivered no longer
+ cause pipelined requests behind them to be rejected as invalid.
+ Reported by Basil Hussain.
+
+- General improvements:
+ - If a pcrs command is rejected as invalid, Privoxy now logs
+ the cause of the problem as text. Previously the pcrs error
+ code was logged.
+ - The tests are less likely to cause false positives.
+
+- Action file improvements:
+ - '.sify.com/' is no longer blocked. Apparently it is not actually
+ a pure tracking site (anymore?). Reported by Andrew on ijbswa-users@.
+ - Unblock banners on .amnesty.de/ which aren't ads.
+
+- Documentation improvements:
+ - The 'Would you like to donate?' section now also contains
+ a "Paypal" address.
+ - The list of supported operating systems has been updated.
+ - The existence of the SF support and feature trackers has been
+ deemphasized because they have been broken for months.
+ Most of the time the mailing lists still work.
+ - The claim that default.action updates are sometimes released
+ on their own has been removed. It hasn't happened in years.
+ - Explicitly mention that Tor's port may deviate from the default
+ when using a bundle. Requested by Andrew on ijbswa-users@.
+
+*** Version 3.0.22 stable ***
+
+- Bug fixes:
+ - Fixed a memory leak when rejecting client connections due to
+ the socket limit being reached (CID 66382). This affected
+ Privoxy 3.0.21 when compiled with IPv6 support (on most
+ platforms this is the default). CVE-2015-1030.
+ - Fixed an immediate-use-after-free bug (CID 66394) and two
+ additional unconfirmed use-after-free complaints made by
+ Coverity scan (CID 66391, CID 66376). CVE-2015-1031.
+ - Actually show the FORCE_PREFIX value on the show-status page.
+ - Properly deal with Keep-Alive headers with timeout= parameters
+ If the timeout still can't be parsed, use the configured
+ timeout instead of preventing the client from keeping the
+ connection alive. Fixes #3615312/#870 reported by Bernard Guillot.
+ - Not using any filter files no longer results in warning messages
+ unless an action file is referencing header taggers or filters.
+ Reported by Stefan Kurtz in #3614835.
+ - Fixed a bug that prevented Privoxy from reusing some reusable
+ connections. Two bit masks with different purpose unintentionally
+ shared the same bit.
+ - A couple of additional bugs were discovered by Coverity Scan.
+ The fixes that are not expected to affect users are not explicitly
+ mentioned here, for details please have a look at the CVS logs.
+
+- General improvements:
+ - Introduced negative tag patterns NO-REQUEST-TAG and NO-RESPONSE-TAG.
+ They apply if no matching tag is found after parsing client or
+ server headers.
+ - Add support for external filters which allow to process the
+ response body with a script or program written in any language
+ the platform supports. External filters are enabled with
+ +external-filter{} after they have been defined in one of the
+ filter files with a header line starting with "EXTERNAL-FILTER:".
+ External filter support is experimental, not compiled by default
+ and known not to work on all platforms.
+ - Add support for the 'PATCH' method as defined in RFC5789.
+ - Reject requests with unsupported Expect header values.
+ Fixes a couple of Co-Advisor tests.
+ - Normalize the HTTP-version in forwarded requests and responses.
+ This is an explicit RFC 2616 MUST and RFC 7230 mandates that
+ intermediaries send their own HTTP-version in forwarded
+ messages.
+ - Server 'Keep-Alive' headers are no longer forwarded. From a user's
+ point of view it doesn't really matter, but RFC 2616 (obsolete)
+ mandates that the header is removed and this fixes a Co-Advisor
+ complaint.
+ - Change declared template file encoding to UTF-8. The templates
+ already used a subset of UTF-8 anyway and changing the declaration
+ allows to properly display UTF-8 characters used in the action files.
+ This change may require existing action files with ISO-8859-1
+ characters that aren't valid UTF-8 to be converted to UTF-8.
+ Requested by Sam Chen in #582.
+ - Do not pass rejected keep-alive timeouts to the server. It might
+ not have caused any problems (we know of), but doing the right
+ thing shouldn't hurt either.
+ - Let log_error() use its own buffer size #define to make changing
+ the log buffer size slightly less inconvenient.
+ - Turned single-threaded into a "proper" toggle directive with arguments.
+ - CGI templates no longer enforce new windows for some links.
+ - Remove an undocumented workaround ('HOST' header removal) for
+ an Apple iTunes bug that according to #729900 got fixed in 2003.
+
+- Action file improvements:
+ - The pattern 'promotions.' is no longer being blocked.
+ Reported by rakista in #3608540.
+ - Disable fast-redirects for .microsofttranslator.com/.
+ - Disable filter{banners-by-size} for .dgb-tagungszentren.de/.
+ - Add adn.speedtest.net as a site-specific unblocker.
+ Support request #3612908.
+ - Disable filter{banners-by-size} for creativecommons.org/.
+ - Block requests to data.gosquared.com/. Reported by cbug in #3613653.
+ - Unblock .conrad./newsletter/. Reported by David Bo in #3614238.
+ - Unblock .bundestag.de/.
+ - Unblock .rote-hilfe.de/.
+ - Disable fast-redirects for .facebook.com/plugins/like.php.
+ - Unblock Stackexchange popup URLs that aren't used to serve ads.
+ Reported by David Wagner in #3615179.
+ - Disable fast-redirects for creativecommons.org/.
+ - Unblock .stopwatchingus.info/.
+ - Block requests for .adcash.com/script/.
+ Reported by Tyrexionibus in #3615289.
+ - Disable HTML filters if the response was tagged as JavaScript.
+ Filtering JavaScript code with filters intended to deal with HTML
+ is usually a waste of time and, more importantly, may break stuff.
+ - Use a custom redirect{} for .washingtonpost.com/wp-apps/imrs\.php\?src=
+ Previously enabling the 'Advanced' settings (or manually enabling
+ +fast-redirects{}) prevented some images from being loaded properly.
+ - Unblock "adina*." Fixes #919 reported by Morton A. Goldberg.
+ - Block '/.*DigiAd'.
+ - Unblock 'adele*.'. Reported by Adele Lime in #1663.
+ - Disable banners-by-size for kggp.de/.
+
+- Filter file improvements & bug fixes:
+ - Decrease the chances that js-annoyances creates invalid JavaScript.
+ Submitted by John McGowan on ijbswa-users@.
+ - Let the msn filter hide 'related' ads again.
+ - Remove a stray '1' in the 'html-annoyances' filter.
+ - Prevent img-reorder from messing up img tags with empty src
+ attributes. Fixes #880 reported by Duncan.
+
+- Documentation improvements:
+ - Updated the 'Would you like to donate?' section.
+ - Note that invalid forward-override{} parameter syntax isn't
+ detected until the parameter is used.
+ - Add another +redirect{} example: a shortcut for illumos bugs.
+ - Make it more obvious that many operating systems support log
+ rotation out of the box.
+ - Fixed dead links. Reported by Mark Nelson in #3614557.
+ - Rephrased the 'Why is the configuration so complicated?' answer
+ to be slightly less condescending. Anonymously suggested in #3615122.
+ - Be more explicit about accept-intercepted-requests's lack of MITM support.
+ - Make 'demoronizer' FAQ entries more generic.
+ - Add an example hostname to the --pre-chroot-nslookup description.
+ - Add an example for a host pattern that matches an IP address.
+ - Rename the 'domain pattern' to 'host pattern' as it may
+ contain IP addresses as well.
+ - Recommend forward-socks5t when using Tor. It seems to work fine and
+ modifying the Tor configuration to profit from it hasn't been necessary
+ for a while now.
+ - Add another redirect{} example to stress that redirect loops can
+ and should be avoided.
+ - The usual spelling and grammar fixes. Parts of them were
+ reported by Reuben Thomas in #3615276.
+ - Mention the PCRS option letters T and D in the filter section.
+ - Clarify that handle-as-empty-doc-returns-ok is still useful
+ and will not be removed without replacement.
+ - Note that security issues shouldn't be reported using the bug tracker.
+ - Clarify what Privoxy does if both +block{} and +redirect{} apply.
+ - Removed the obsolete bookmarklets section.
+
+- Build system improvements:
+ - Let --with-group properly deal with secondary groups.
+ Patch submitted by Anatoly Arzhnikov in #3615187.
+ - Fix web-actions target.
+ - Add a web-faq target that only updates the FAQ on the webserver.
+ - Remove already-commented-out non-portable DOSFILTER alternatives.
+ - Remove the obsolete targets dok-put and dok-get.
+ - Add a sf-shell target.
+
+*** Version 3.0.21 stable ***
+
+- Bug fixes:
+ - On POSIX-like platforms, network sockets with file descriptor
+ values above FD_SETSIZE are properly rejected. Previously they
+ could cause memory corruption in configurations that allowed
+ the limit to be reached.
+ - Proxy authentication headers are removed unless the new directive
+ enable-proxy-authentication-forwarding is used. Forwarding the
+ headers potentially allows malicious sites to trick the user
+ into providing them with login information.
+ Reported by Chris John Riley.
+ - Compiles on OS/2 again now that unistd.h is only included
+ on platforms that have it.
+
+- General improvements:
+ - The show-status page shows the FEATURE_STRPTIME_SANITY_CHECKS status.
+ - A couple of assert()s that could theoretically dereference
+ NULL pointers in debug builds have been relocated.
+ - Added an LSB info block to the generic start script.
+ Based on a patch from Natxo Asenjo.
+ - The max-client-connections default has been changed to 128
+ which should be more than enough for most setups.
+
+- Action file improvements:
+ - Block rover.ebay./ar.*\&adtype= instead of "/.*\&adtype=" which
+ caused too man false positives.
+ Reported by u302320 in #360284, additional feedback from Adam Piggott.
+ - Unblock '.advrider.com/' and '/.*ADVrider'.
+ Anonymously reported in #3603636.
+ - Stop blocking '/js/slider\.js'.
+ Reported by Adam Piggott in #3606635 and _lvm in #2791160.
+
+- Filter file improvements:
+ - Added an iframes filter.
+
+- Documentation improvements:
+ - The whole GPLv2 text is included in the user manual now,
+ so Privoxy can serve it itself and the user can read it
+ without having to wade through GPLv3 ads first.
+ - Properly numbered and underlined a couple of section titles
+ in the config that where previously overlooked due to a flaw
+ in the conversion script. Reported by Ralf Jungblut.
+ - Improved the support instruction to hopefully make it harder to
+ unintentionally provide insufficient information when requesting
+ support. Previously it wasn't obvious that the information we need
+ in bug reports is usually also required in support requests.
+ - Removed documentation about packages that haven't been provided
+ in years.
+
+- Privoxy-Regression-Test:
+ - Only log the test number when not running in verbose mode
+ The position of the test is rarely relevant and it previously
+ wasn't exactly obvious which one of the numbers was useful to
+ repeat the test with --test-number.
+
+- GNUmakefile improvements:
+ - Factor generate-config-file out of config-file to make testing
+ more convenient.
+ - The clean target now also takes care of patch leftovers.
+
+*** Version 3.0.20 beta ***
- Bug fixes:
- Client sockets are now properly shutdown and drained before being
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.
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.
- - 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.
- 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 each
- request that Privoxy acts upon.
- - New directive client-header-order can be used to forward client headers in
- a different order than that in which they arrived.
- - New directive tolerate-pipelining can be used to enable 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
+ - 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 lets Privoxy exit after checking whether or not
+ - 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. Logging the problem to the logfile if one is configured and
- --no-daemon isn't used could be considered non-intuitive and might also
- clobber messages emitted by an already running instance. Based on a patch
- by Ramkumar Chinchani.
- - Add limit-cookie-lifetime{} action. It can be used to let cookies expire
- before the end of the session. limit-cookie-lifetime{0} creates session
- cookies and can thus replace the session-cookies-only action in the future.
- Idea originally suggested by Rick Sykes in #1049575.
+ 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
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.
+ - Stop considering client sockets tainted after receiving 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
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 in
- accept_connection(). This should further reduce the chances of the client
- getting an incomplete response, even though Privoxy wrote it in its
- entirety to the socket.
+ - Set the socket option SO_LINGER for the client socket.
- Move several variable declarations to the beginning of their code block.
- It's how we usually do it and is apparently also required when compiling
- with gcc 2.95. Initial patch submitted by Simon South in #3564815.
- - Optionally let parse_header_time() 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:
- http://www.freebsd.org/cgi/query-pr.cgi?pr=173421
- - Attempt to work around (or at least reduce the) video playback issues with
- various Apple clients as reported in #3426305. In client_range(), let
- headers pass if the range starts at the beginning.
+ 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
- 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.
- Action file improvements:
- - Remove the comment that indicated that updated versions of this file are
- released on their own.
+ - Remove the comment that indicated that updated default.action versions
+ are released on their own.
- Block 'optimize.indieclick.com/' and 'optimized-by.rubiconproject.com/'
- Unblock 'adjamblog.wordpress.com/' and 'adjamblog.files.wordpress.com/'.
Reported by Ryan Farmer in #3496116.
- Block '/openx/www/delivery/'.
- Disable fast-redirects for '.googleapis.com/'.
- Block 'imp.double.net/'. Reported by David Bo in #3070411.
- - Block 'gm-link.com/' whis is used for email tracking.
+ - Block 'gm-link.com/' which is used for email tracking.
Reported by David Bo in #1812733.
- Verify that requests to "bwp." are blocked. URL taken from #1736879
submitted by Francois Marier.
- Spell 'refresh-tags' correctly. Reported by Don in #3571927.
- Sort manpage options alphabetically.
- Remove an incorrect sentence in the toggle section. The toggle state
- doesn't affect whether or not the Windows version uses the tray icon and
- having to toggle Privoxy off to not show the icon makes no sense anyway.
+ doesn't affect whether or not the Windows version uses the tray icon.
Reported by Zeno Kugy in #3596395.
- - Add the DNT header to the client-header-order example.
- Add new contributors since 3.0.19.
- Log message improvements:
- When stopping to watch a client socket due to pipelining, additionally log
the socket number.
- - log the client socket and its condition before closing it. This makes it
+ - Log the client socket and its condition before closing it. This makes it
more obvious that the socket actually gets closed and should help when
diagnosing problems like #3464439.
- In case of SOCKS5 failures, do not explicitly log the server's response.
"debug 32768" anyway. This reverts v1.81 and the follow-up bug fix v1.84.
- Relocate the connection-accepted message from listen_loop() to serve().
This way it's printed by the thread that is actually serving the
- connection which is nice when grepping for thread ids in log files. While
- at it, use an upper-case first character which is more consistent with the
- other log messages.

- Code cleanups:
- Remove compatibility layer for versions prior to 3.0 since it has been
- Various data type corrections.
- Change visibility of several code segments when compiling without
FEATURE_CONNECTION_KEEP_ALIVE enabled for clarity.
- - In pcrs_get_delimiter(), do not use delimiters ouside the ASCII range.
+ - In pcrs_get_delimiter(), do not use delimiters outside the ASCII range.
Fixes a clang complaint.
- Fix an error message in get_last_url() nobody is supposed to see.
Reported by Matthew Fischer in #3507301.
- Fix a typo in the no-zlib-support complaint. Patch submitted by Matthew
Fischer in #3507304.
- - Update an error message that still tried to print directive_hash as long
- Shorten ssplit()'s prototype by removing the last two arguments. We always
want to skip empty fields and ignore leading delimiters, so having
parameters for this only complicates the API.
- Turn family mismatches in match_sockaddr() into fatal errors.
- Let enlist_unique_header() verify that the caller didn't pass a header
containing either \r or \n.
- - Change the hashes used in load_config() to unsigned int.
- That's what hash_string() actually returns and using a potentiallly larger
- type is at best useless.
+ - Change the hashes used in load_config() to unsigned int. That's what
+ hash_string() actually returns and using a potentially larger type

- Use privoxy_tolower() instead of vanilla tolower() with manual casting of
the argument.
+ - Catch ssplit() failures in parse_cgi_parameters().
- Privoxy-Regression-Test:
+ - Add an 'Overwrite condition' directive to skip any matching tests before
+ it. As it has a global scope, using it is more convenient than clowning
+ around with the Ignore directive.
+ - Log to STDOUT instead of STDERR.
+ - Include the Privoxy version in the output.
- Various grammar and spelling corrections in documentation and code.
- Additional tests for range requests with filtering enabled.
- Tests with mostly invalid range request.
- - Log to STDOUT instead of STDERR.
- Add a couple of hide-if-modified-since{} tests with different date formats.
- Cleaned up the format of the regression-tests.action file to match the

- Remove the "Copyright" line from print_version(). When using --help, every
line of screen space matters and thus shouldn't be wasted on things the
user doesn't care about.
- - Fix comment typos.
- - Add an 'Overwrite condition' directive to skip any matching tests before
- it. As it has a global scope, using it is more convenient than clowning
- around with the Ignore directive.
- - Include the Privoxy version in the output.
- Privoxy-Log-Parser:
- Improve the --statistics performance by skipping sanity checks for input
- that shouldn't affect the results anyway. In my non-scientific benchmarks
- this reduces the runtime by about 45%. Also add a --strict-checks option
+ that shouldn't affect the results anyway. Add a --strict-checks option
that enables some of the checks again, just in case anybody cares.
- - Accept and highlight: Stopping to watch the client socket. There's already
- another request waiting.
- - Cleanup variable initialization in print_non_clf_message().
- - Properly highlight the new log messages from get_request_line().

- - Accept and ignore: Enlisting (sorted|left-over) header ...
- - Accept the shiny new LOG_LEVEL_ACTIONS.
- - Accept and highlight: Closing client socket 5. Keep-alive: 0, Socket

- - Accept and highlight: Client request 8 has been pipelined on socket 7 and
- the socket is still alive.
- - Accept: There better be a request body.
- - Accept and highlight: Shifting 360 pipelined bytes by 360 bytes.
- - Accept and highlight: Multiple Content-Type headers detected. Removing and
- ignoring: Content-Type: text/html.
+ - The distribution of client requests per connection is included in
+ the --statistic output.
+ - The --accept-unknown-messages option has been removed and the behavior

- - Bump generated Firefox version to 16.

-- CGI interface improvements & bug fixes:
- - Remove an unreasonable parameter limit in parse_cgi_parameters(). 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@.
- - Catch ssplit() failures in parse_cgi_parameters().
- - Deal with unsupported methods sent to the CGI pages by discarding any
- data following the headers.
+ - Bump generated Firefox version to 17.
- GNUmakefile improvements:
- The dok-tidy target no longer taints documents with a tidy-mark
- Let w3m itself do the line wrapping for the config file. It works better
than fmt as it can honour pre tags causing less unintentional line breaks.
- Ditch a pointless '-r' passed to rm to delete files.
- - Prevent completely empty lines in configure and try to unfold
- unintentional line breaks.
- - Let the config-file target optimistically update the original. Most of the
- issues are fixed now and it makes diffing with git easier.
+ - The config-file target now requires less manual intervention and updates
+ the original config.
- Change WDUMP to generate ASCII. Add WDUMP_UTF8 to allow UTF-8 in the
AUTHORS file so the names are right.
- Stop pretending that lynx and links are supported for the documentation.
- configure improvements:
- On Haiku, do not pass -lpthread to the compiler. Haiku's pthreads
implementation is contained in its system library, libroot, so no
- additional library needs to be searched. Patch submitted by Simon South in
- #3564815.
+ additional library needs to be searched.
+ Patch submitted by Simon South in #3564815.
- Additional Haiku-specific improvements. Disable checks intended for
multi-user systems as Haiku is presently single-user. Group Haiku-specific
settings in their own section, following the pattern for Solaris, OS/2 and
AmigaOS. Add additional library-related settings to remove the need for
- providing configure with custom LDFLAGS. Submitted by Simon South in
- #3574538.
- - Several improvements for clarity, diffability and logic.
