-ChangeLog for Internet JunkBuster
+ChangeLog for Privoxy
--------------------------------------------------------------------
+*** Version 3.0.28 stable ***
-*** Version 2.9.13 Beta ***
+- Bug fixes for regressions in 3.0.27:
+ - Fixed misplaced parentheses.
+ Reported by David Binderman.
+ - Changed two regression tests to depend on config directive
+ enable-remote-toggle instead of FEATURE_TOGGLE.
-- *NEWS*: The project has been renamed to Privoxy! The new name is
-reflected throughout (file locations, etc).
-- ijb.action is now default.action. re_filterfile is now
-default.filter.
+*** Version 3.0.27 stable ***
+
+- General improvements:
+ - Add a receive-buffer-size directive which can be used to
+ set the size of the previously statically allocated buffer
+ in handle_established_connection().
+ Increasing the buffer size increases Privoxy's memory usage but
+ can lower the number of context switches and thereby reduce the
+ CPU usage and potentially increase the throughput.
+ This is mostly relevant for fast network connections and
+ large downloads that don't require filtering.
+ Sponsored by: Robert Klemme
+ - Add a listen-backlog directive which specifies the backlog
+ value passed to listen().
+ Sponsored by: Robert Klemme
+ - Add an enable-accept-filter directive which allows to
+ toggle accept filter support at run time when compiled
+ with FEATURE_ACCEPT_FILTER support.
+ It makes testing more convenient and now that it's
+ optional we can emit an error message if enabling
+ the accept filter fails.
+ Sponsored by: Robert Klemme
+ - Add a delay-response{} action.
+ This is useful to tar pit JavaScript requests that
+ are endlessly retried in case of blocks. It can also
+ be used to simulate a slow Internet connection.
+ Sponsored by: Robert Klemme
+ - Add a 'trusted-cgi-referrer' directive.
+ It allows to configure another page or site that can be used
+ to reach sensitive CGI resources.
+ Sponsored by: Robert Klemme
+ - Add a --fuzz mode which exposes Privoxy internals to input
+ from files or stdout.
+ Mainly tested with American Fuzzy Lop. For details see:
+ https://www.fabiankeil.de/talks/fuzzing-on-freebsd/
+ This work was partially funded with donations and done
+ as part of the Privoxy month in 2015.
+ - Consistently use the U(ngreedy) flag in the 'img-reorder' filter.
+ - listen_loop(): Reuse a single thread attribute object
+ The object doesn't change and creating a new one for
+ every thread is a waste of (CPU) time.
+ Sponsored by: Robert Klemme
+ - Free csp resources in the thread that belongs to the csp instead
+ of the main thread which has enough on its plate already.
+ Sponsored by: Robert Klemme
+ - Improve 'socket timeout reached' message.
+ Log the timeout that was triggered and downgrade the
+ log level to LOG_LEVEL_CONNECT to reduce the log noise
+ with common debug settings.
+ The timeout isn't necessary the result of an error and
+ usually merely indicates that Privoxy's socket timeout
+ is lower than the relevant timeouts used by client and
+ server.
+ Sponsored by: Robert Klemme
+ - Explicitly taint the server socket in case of CONNECT requests.
+ This doesn't fix any known problems, but makes
+ some log messages less confusing.
+ - Let write_pid_file() terminate if the pid file can't be opened.
+ Logging the issue at info level is unlikely to help.
+ - log_error(): Reduce the mutex-protected area by not using a
+ heap-allocated buffer that is shared between all threads.
+ This increases performance and reduces the latency with
+ verbose debug settings and multiple concurrent connections.
+ Sponsored by: Robert Klemme
+ - Let zalloc() use calloc() if it's available.
+ In some situations using calloc() can be faster than
+ malloc() + memset() and it should never be slower.
+ In the real world the impact of this change is not
+ expected to be noticeable.
+ Sponsored by: Robert Klemme
+ - Never use select() when poll() is available.
+ On most platforms select() is limited by FD_SETSIZE while
+ poll() is not. This was a scaling issue for multi-user setups.
+ Using poll() has no downside other than the usual risk
+ that code modifications may introduce new bugs that have
+ yet to be found and fixed.
+ At least in theory this commit could also reduce the latency
+ when there are lots of connections and select() would use
+ "bit fields in arrays of integers" to store file descriptors.
+ Another side effect is that Privoxy no longer has to stop
+ monitoring the client sockets when pipelined requests are
+ waiting but can't be read yet.
+ This code keeps the select()-based code behind ifdefs for
+ now but hopefully it can be removed soonish to make the
+ code more readable.
+ Sponsored by: Robert Klemme
+ - Add a 'reproducible-tarball-dist' target.
+ It's currently separate from the "tarball-dist" target
+ because it requires a tar implementation with mtree spec
+ support.
+ It's far from being perfect and does not enforce a
+ reproducible mode, but it's better than nothing.
+ - Use arc4random() if it's available.
+ While Privoxy doesn't need high quality pseudo-random numbers
+ there's no reason not to use them when we can and this silences
+ a warning emitted by code checkers that can't tell whether or not
+ the quality matters.
+ - Show the FEATURE_EXTERNAL_FILTERS status on the status page.
+ Better late than never. Previously a couple of tests weren't
+ executed as Privoxy-Regression-Test couldn't detect that the
+ FEATURE_EXTERNAL_FILTERS dependency was satisfied.
+ - Ditch FEATURE_IMAGE_DETECT_MSIE.
+ It's an obsolete workaround we inherited from Junkbuster
+ and was already disabled by default.
+ Users that feel the urge to work around issues with
+ image requests coming from an Internet Explorer version
+ from more than 15 years ago can still do this using tags.
+ - Consistently use strdup_or_die() instead of strdup() in
+ cases where allocation failures aren't expected.
+ Using strdup_or_die() allows to remove a couple of explicit
+ error checks which slightly reduces the size of the binary.
+ - Insert a refresh tag into the /client-tags CGI page when
+ serving it while a client-specific tag is temporarily enabled.
+ This makes it less likely that the user ends up
+ looking at tag state that is out of date.
+ - Use absolute URLs in the client-tag forms.
+ It's more consistent with the rest of the CGI page
+ URLs and makes it more convenient to copy the forms
+ to external pages.
+ - cgi_error_disabled(): Use status code 403 and an appropriate response line
+ - Use a dedicated CGI handler to deal with tag-toggle requests
+ As a result the /client-tags page is now safe to reach without
+ trusted Referer header which makes bookmarking or linking to
+ it more convenient.
+ Finally, refreshing the /client-tags page to show the
+ current state can no longer unintentionally repeat the
+ previous toggle request.
+ - Don't add a "Connection" header for CONNECT requests.
+ Explicitly sending "Connection: close" is not necessary and
+ apparently it causes problems with some forwarding proxies
+ that will close the connection prematurely.
+ Reported by Marc Thomas.
+ - Fix compiler warnings.
+
+- Bug fixes:
+ - rfc2553_connect_to(): Properly detect and log when poll()
+ reached the time out. Previously this was logged as:
+ Could not connect to [...]: No error: 0.
+ which isn't very helpful.
+ Sponsored by: Robert Klemme
+ - add_tag_for_client(): Set time_to_live properly.
+ Previously the time_to_live was always set for the first tag.
+ Attempts to temporarily enable a tag would result in enabling
+ it permanently unless no tag was enabled already.
+ - Revert r1.165 which didn't perform as advertised.
+ While the idea was to use "https:// when creating links
+ for the user manual on the website", the actual effect
+ was to use "https://" when Privoxy was supposed to serve
+ the user manual itself.
+ Reported by Yossi Zahn on Privoxy-devel@.
+ - socks5_connect(): Fail in case of unsupported address types.
+ Previously they would not be detected right away and
+ Privoxy would fail later on with an error message that
+ didn't make it obvious that the problem was socks-related.
+ So far, no such problems have actually been reported.
+ - socks5_connect(): Properly deal with socks replies that
+ contain IPv6 addresses.
+ Previously parts of the reply were left unread and
+ later on treated as invalid HTTP response data.
+ Fixes #904 reported by Danny Goossen who also provided
+ the initial version of this patch.
+
+- Action file improvements:
+ - Unblock 'msdn.microsoft.com/'.
+ It (presumably) isn't used to serve the kind of ads Privoxy should
+ block by default but happens to serve lots of pages with URLs that
+ are likely to result in false positives.
+ Reported by bugreporter1694 in AF#939.
+ - Disable gif deanimation for requests tagged with CSS-REQUEST.
+ The action will ignore content that isn't considered text
+ anyway and explicitly disabling it makes this more obvious
+ if "action" debugging (debug 65536) is enabled while
+ "gif deanimation" debugging (debug 256) isn't.
+ - Explicitly disable HTML filters for requests with CSS-REQUEST tag.
+ The filters are unlikely to break CSS files but executing
+ them without (intentionally) getting any hits is a waste of
+ cpu time and makes the log more noisy when running with
+ "debug 64".
+ - Unblock 'adventofcode.com/'.
+ Reported by Clint Adams in Debian bug #848211.
+ Fixes Roland's AF#937.
+ - Unblock 'adlibris.com'.
+ Reported by Wyrex in #935
+ - Unblock .golang.org/
+ - Add fast-redirects exception for '.youtube.com/.*origin=http'
+
+- Privoxy-Log-Parser:
+ - Don't gather host and resource statistics if they aren't requested.
+ While the performance impact seems negligible this significantly
+ reduces the memory usage if there are lots of requests.
+ - Bump version as the behaviour (slightly) changed.
+ - Count connection failures as well in statistics mode.
+ Sponsored by: Robert Klemme
+ - Count connection timeouts as well in statistics mode.
+ Sponsored by: Robert Klemme
+ - Fix an 'uninitialized value' warning when generating
+ statistics for a log file without response headers.
+ While privoxy-log-parser was supposed to detect this already,
+ the check was flawed and the message the user didn't see was
+ somewhat confusing anyway.
+ Now the message is less confusing, more helpful and actually printed.
+ Reported by: Robert Klemme
+
+- Documentation improvements:
+ - Refer to the git sources instead of CVS.
+ - Use GNU/Linux when referring to the OS instead of the kernel.
+ - Add FAQ entry for what to do if editing the config file is access denied.
+ - Add brief HTTP/2 FAQ.
+ - Add a small fuzzing section to the developer documentation.
+ - Add a client-header-tagger{client-ip-address} example.
+ - Stop suggesting that Privoxy is an anonymizing proxy.
+ The term could lead to Privoxy users overestimating
+ what it can do on its own (without Tor).
+ - Make it more obvious that SPI accepts Paypal, too.
+ Currently most donations are made through the Paypal account
+ managed by Zwiebelfreunde e.V. and a more even distribution
+ would be useful.
+ - Suggest to log applying actions as well when reproducing problems.
+ - Explicitly mention that Privoxy binaries are built by individuals
+ on their own systems. Buyer beware!
+ - Mention the release feed on the homepage.
+ - Remove a mysterious comment with a GNU FDL link as it isn't
+ useful and could confuse license scanners.
+ In May 2002 it was briefly claimed that "this document" was covered
+ by the GNU FDL. The commit message (r1.5) doesn't explain the motivation
+ or whether all copyright holders were actually asked and agreed to the
+ declared license change.
+ It's thus hard to tell whether or not the license change was legit,
+ but luckily two days later the "doc license" was "put" "back to GPL"
+ anyway (r1.6).
+ At the same time the offending comment with a link to the FDL
+ (not the GPL) was added for no obvious reason.
+ Now it's gone again.
+
+- Regression tests:
+ - Bump for-privoxy-version to 3.0.27 as we now rely on untrusted
+ CGI request being rejected with status code 403 (instead of 200).
+ - Update test for /send-stylesheet and add another one
+
+- Templates:
+ - Consistently use https:// when linking to the Privoxy website.
+ - Remove SourceForge references in Copyright header.
+ - Remove a couple of SourceForge references in a comment.
+ While at it, fix the grammar.
+ - Move the site-specific documentation block before the generic one.
+ While most Privoxy installations don't have a site-specific
+ documentation block, in cases were it exists it's likely to
+ be more relevant than the generic one.
+ Showing it first makes it less likely that users stop reading
+ before they reach it, especially on pages that don't fit on
+ the screen.
+
+- Build system improvements:
+ - Prefer openjade to jade. On some systems Jade produces
+ HTML with unescaped ampersands in URLs.
+ - Prefer OpenSP to SP to be consistent.
+ - Have Docbook generated HTML files be straight ASCII.
+ Dealing with a mixture of ISO-8859 and UTF-8 files is problematic.
+ - Echo the filename to stderr for 'make dok-tidy'.
+ Make it a bit easier to find errors in docbook generated HTML.
+ - Warn when still using select().
+ - Warn when compiling without calloc().
+ - Make it more obvious that the --with-fdsetsize configure switch
+ is pointless if poll() is available.
+ - Remove support for AmigaOS.
+ - Update windows build system to use supported software.
+ The cygwin gcc -mno-cygwin option is no longer supported, so
+ convert the windows build system to use the cygwin cross-compiler
+ to build "native" code.
+ - Add --enable-static-linking option for configure
+ does the same thing as LDFLAGS=-static; ./configure
+ but nicer than mixing evars and configure options.
+
+*** Version 3.0.26 stable ***
+
+- Bug fixes:
+ - Fixed crashes with "listen-addr :8118" (SF Bug #902).
+ The regression was introduced in 3.0.25 beta and reported
+ by Marvin Renich in Debian bug #834941.
+
+- General improvements:
+ - Log when privoxy is toggled on or off via cgi interface.
+ - Highlight the "Info: Now toggled " on/off log message
+ in the Windows log viewer.
+ - Highlight the loading actions/filter file log message
+ in the Windows log viewer.
+ - Mention client-specific tags on the toggle page as a
+ potentionally more appropriate alternative.
+
+- Documentation improvements:
+ - Update download section on the homepage.
+ The downloads are available from the website now.
+ - Add sponsor FAQ.
+ - Remove obsolete reference to mailing lists hosted at SourceForge.
+ - Update the "Before the Release" section of the developer manual.
+
+- Infrastructure improvements:
+ - Add perl script to generate an RSS feed for the packages
+ Submitted by "Unknown".
+
+- Build system improvements:
+ - strptime.h: fix a compiler warning about ambiguous else.
+ - configure.in: Check for Docbook goo on the BSDs as well.
+ - GNUMakefile.in: Let the dok-user target remove temporary files.
+
+*** Version 3.0.25 beta ***
+
+- Bug fixes:
+ - 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:
+ - 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.
+
+*** 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
+ 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 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
+ 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.
+
+- Action file improvements:
+ - 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.
+ - Unblock '/.*Bugtracker'. Reported by pwhk in #3522341.
+ - Add test URLs for '.freebsd.org' and '.watson.org'.
+ - Unblock '.urbandictionary.com/popular'.
+ - Block '.adnxs.com/'.
+ - Block 'farm.plista.com/widgetdata.php'.
+ - Block 'rotation.linuxnewmedia.com/'.
+ - Block 'reklamy.sfd.pl/'. Reported by kacperdominik in #3399948.
+ - Block 'g.adspeed.net/'.
+ - Unblock 'websupport.wdc.com/'. Reported by Adam Piggot in #3577851.
+ - Block '/openx/www/delivery/'.
+ - Disable fast-redirects for '.googleapis.com/'.
+ - Block 'imp.double.net/'. Reported by David Bo in #3070411.
+ - 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.
+ - Block '/.*bannerid='. Reported by Adam Piggott in #2975779.
+ - Block 'cltomedia.info/delivery/' and '.adexprt.com/'.
+ Anonymously reported in #2965254.
+ - Block 'de17a.com/'. Reported by David Bo in #3061472.
+ - Block 'oskar.tradera.com/'. Reported by David Bo in #3060596.
+ - Block '/scripts/webtrends\.js'. Reported by johnd16 in #3002729.
+ - Block requests for 'pool.*.adhese.com/'. Reported by johnd16 in #3002716.
+ - Update path pattern for Coremetrics and add tests.
+ Pattern and URLs submitted by Adam Piggott #3168443.
+ - Enable +fast-redirects{check-decoded-url} for 'tr.anp.se/'.
+ Reported by David Bo in #3268832.
+ - Unblock '.conrad.se/newsletter/banners/'. Reported by David Bo in #3413824.
+ - Block '.tynt.com/'. Reported by Dan Stahlke in #3421767.
+ - Unblock '.bbci.co.uk/radio/'. Reported by Adam Piggott in #3569603.
+ - Block requests to 'service.maxymiser.net/'.
+ Reported by johnd16 in #3118401 (with a previous URL).
+ - Disable fast-redirects for Google's "let's pretend your computer is
+ infected" page.
+ - Unblock '/.*download' to resolve actionsfile feedback #3498129.
+ Submitted by Steven Kolins (soundcloud.com not working).
+ - Unblock '.wlxrs.com/' which is required by hotmail.com.
+ Fixes #3413827 submitted by David Bo.
+ - Add two unblock patterns for popup radio and TV players.
+ Submitted by Adam Piggott in #3596089.
+
+- Filter file improvements & bug fixes:
+ - Add a referer tagger.
+ - Reduce the likelihood that the google filter messes up HTML-generating
+ JavaScript. Reported by Zeno Kugy in #3520260.
+
+- Documentation improvements:
+ - Revised all OS X sections due to new packaging module (OSXPackageBuilder).
+ - Update the list of supported operating systems to clarify that all Windows
+ versions after 95 are expected to work and note that the platform-specific
+ code for AmigaOS and QNX currently isn't maintained.
+ - Update 'Signals' section, the only explicitly handled signals are SIGINT,
+ SIGTERM and SIGHUP.
+ - Add Haiku to the list of operating systems on which Privoxy is known to
+ run.
+ - Add DragonFly to the list of BSDs on which Privoxy is known to run.
+ - Removed references to redhat-specific documentation set since it no longer
+ exists.
+ - Removed references to building PDFs since we no longer do so.
+ - Multiple listen-address directives are supported since 3.0.18, correct the
+ documentation to say so.
+ - Remove bogus section about long and short being preferable to int.
+ - Corrected some Internet JunkBuster references to Privoxy.
+ - Removed references to www.junkbusters.com since it is no longer
+ maintained. Reported by Angelina Matson.
+ - Various grammar and spelling corrections
+ - Add a client-header-tagger{} example for disabling filtering for range
+ requests.
+ - Correct a URL in the "Privoxy with Tor" FAQ.
+ - 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.
+ Reported by Zeno Kugy in #3596395.
+ - 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
+ 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.
+ It hasn't helped so far and the response can already be logged by enabling
+ "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.
+
+- Code cleanups:
+ - Remove compatibility layer for versions prior to 3.0 since it has been
+ obsolete for more than 10 years now.
+ - Remove the ijb_isupper() and ijb_tolower() macros from parsers.c since
+ they aren't used in this file.
+ - Removed the 'Functions declared include:' comment sections since they tend
+ to be incomplete, incorrect and out of date and the benefit seems
+ questionable.
+ - Various comment grammar and comprehensibility improvements.
+ - Remove a pointless fflush() call in chat(). Flushing all streams pretty
+ much all the time for no obvious reason is ridiculous.
+ - Relocate ijb_isupper()'s definition to project.h and get the ijb_tolower()
+ definition from there, too.
+ - Relocate ijb_isdigit()'s definition to project.h.
+ - Rename ijb_foo macros to privoxy_foo.
+ - Add malloc_or_die() which will allow to simplify code paths where malloc()
+ failures don't need to be handled gracefully.
+ - Add strdup_or_die() which will allow to simplify code paths where strdup()
+ failures don't need to be handled gracefully.
+ - Replace strdup() calls with strdup_or_die() calls where it's safe and
+ simplifies the code.
+ - Fix white-space around parentheses.
+ - Add missing white-space behind if's and the following parentheses.
+ - Unwrap a memcpy() call in resolve_hostname_to_ip().
+ - Declare pcrs_get_delimiter()'s delimiters[] static const.
+ - Various optimisations to remove dead code and merge inefficient code
+ structures for improved clarity, performance or code compactness.
+ - 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 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.
+ - 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.
+ - Use an enum for the type of the action value.
+ - Rename action_name's member takes_value to value_type as it isn't used as
+ boolean.
+ - 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 potentially larger type
+ is at best useless.
+ - 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.
+ - 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
+ format of default.action.
+ - 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.
+
+- Privoxy-Log-Parser:
+ - Improve the --statistics performance by skipping sanity checks for input
+ that shouldn't affect the results anyway. Add a --strict-checks option
+ that enables some of the checks again, just in case anybody cares.
+ - The distribution of client requests per connection is included in
+ the --statistic output.
+ - The --accept-unknown-messages option has been removed and the behavior
+ is now the default.
+ - Accept and (mostly) highlight new log messages introduced with
+ Privoxy 3.0.20.
+
+- uagen:
+ - Bump generated Firefox version to 17.
+
+- GNUmakefile improvements:
+ - The dok-tidy target no longer taints documents with a tidy-mark
+ - Change RA_MODE from 0664 to 0644. Suggested by Markus Dittrich in
+ #3505445.
+ - Remove tidy's clean flag as it changes the scope of attributes.
+ Link-specific colors end up being applied to all text. Reported by Adam
+ Piggott in #3569551.
+ - Leave it up to the user whether or not smart tags are inserted.
+ - 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.
+ - 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 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.
+
+*** 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.
+
+- 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.
+
+*** Version 3.0.18 Stable ***
+
+- Bug fixes:
+ - If a generated redirect URL contains characters RFC 3986 doesn't
+ permit, they are (re)encoded. Not doing this makes Privoxy versions
+ from 3.0.5 to 3.0.17 susceptible to HTTP response splitting (CWE-113)
+ attacks if the +fast-redirects{check-decoded-url} action is used.
+ - Fix a logic bug that could cause Privoxy to reuse a server
+ socket after it got tainted by a server-header-tagger-induced
+ block that was triggered before the whole server response had
+ been read. If keep-alive was enabled and the request following
+ the blocked one was to the same host and using the same forwarding
+ settings, Privoxy would send it on the tainted server socket.
+ While the server would simply treat it as a pipelined request,
+ Privoxy would later on fail to properly parse the server's
+ response as it would try to parse the unread data from the
+ first response as server headers for the second one.
+ Regression introduced in 3.0.17.
+ - When implying keep-alive in client_connection(), remember that
+ the client didn't. Fixes a regression introduced in 3.0.13 that
+ would cause Privoxy to wait for additional client requests after
+ receiving a HTTP/1.1 request with "Connection: close" set
+ and connection sharing enabled.
+ With clients which terminates the client connection after detecting
+ that the whole body has been received it doesn't really matter,
+ but with clients that don't the connection would be kept open until
+ it timed out.
+ - Fix a subtle race condition between prepare_csp_for_next_request()
+ and sweep(). A thread preparing itself for the next client request
+ could briefly appear to be inactive.
+ If all other threads were already using more recent files,
+ the thread could get its files swept away under its feet.
+ So far this has only been reproduced while stress testing in
+ valgrind while touching action files in a loop. It's unlikely
+ to have caused any actual problems in the real world.
+ - Disable filters if SDCH compression is used unless filtering is forced.
+ If SDCH was combined with a supported compression algorithm, Privoxy
+ previously could try to decompress it and ditch the Content-Encoding
+ header even though the SDCH compression wasn't dealt with.
+ Reported by zebul666 in #3225863.
+ - Make a copy of the --user value and only mess with that when splitting
+ user and group. On some operating systems modifying the value directly
+ is reflected in the output of ps and friends and can be misleading.
+ Reported by zepard in #3292710.
+ - If forwarded-connect-retries is set, only retry if Privoxy is actually
+ forwarding the request. Previously direct connections would be retried
+ as well.
+ - Fixed a small memory leak when retrying connections with IPv6
+ support enabled.
+ - Remove an incorrect assertion in compile_dynamic_pcrs_job_list()
+ It could be triggered by a pcrs job with an invalid pcre
+ pattern (for example one that contains a lone quantifier).
+ - If the --user argument user[.group] contains a dot, always bail out
+ if no group has been specified. Previously the intended, but undocumented
+ (and apparently untested), behaviour was to try interpreting the whole
+ argument as user name, but the detection was flawed and checked for '0'
+ instead of '\0', thus merely preventing group names beginning with a zero.
+ - In html_code_map[], use a numeric character reference instead of '
+ which wasn't standardized before XHTML 1.0.
+ - Fix an invalid free when compiled with FEATURE_GRACEFUL_TERMINATION
+ and shut down through http://config.privoxy.org/die
+ - In get_actions(), fix the "temporary" backwards compatibility hack
+ to accept block actions without reason.
+ It also covered other actions that should be rejected as invalid.
+ Reported by Billy Crook.
+
+- General improvements:
+ - Privoxy can (re)compress buffered content before delivering
+ it to the client. Disabled by default as most users wouldn't
+ benefit from it.
+ - The +fast-redirects{check-decoded-url} action checks URL
+ segments separately. If there are other parameters behind
+ the redirect URL, this makes it unnecessary to cut them off
+ by additionally using a +redirect{} pcrs command.
+ Initial patch submitted by Jamie Zawinski in #3429848.
+ - When loading action sections, verify that the referenced filters
+ exist. Currently missing filters only result in an error message,
+ but eventually the severity will be upgraded to fatal.
+ - Allow to bind to multiple separate addresses.
+ Patch set submitted by Petr Pisar in #3354485.
+ - Set socket_error to errno if connecting fails in rfc2553_connect_to().
+ Previously rejected direct connections could be incorrectly reported
+ as DNS issues if Privoxy was compiled with IPv6 support.
+ - Adjust url_code_map[] so spaces are replaced with %20 instead of '+'
+ While '+' can be used by client's submitting form data, this is not
+ actually what Privoxy is using the lookups for. This is more of a
+ cosmetic issue and doesn't fix any known problems.
+ - When compiled without FEATURE_FAST_REDIRECTS, do not silently
+ ignore +fast-redirect{} directives
+ - Added a workaround for GNU libc's strptime() reporting negative
+ year values when the parsed year is only specified with two digits.
+ On affected systems cookies with such a date would not be turned
+ into session cookies by the +session-cookies-only action.
+ Reported by Vaeinoe in #3403560
+ - Fixed bind failures with certain GNU libc versions if no non-loopback
+ IP address has been configured on the system. This is mainly an issue
+ if the system is using DHCP and Privoxy is started before the network
+ is completely configured.
+ Reported by Raphael Marichez in #3349356.
+ Additional insight from Petr Pisar.
+ - Privoxy log messages now use the ISO 8601 date format %Y-%m-%d.
+ It's only slightly longer than the old format, but contains
+ the full date including the year and allows sorting by date
+ (when grepping in multiple log files) without hassle.
+ - In get_last_url(), do not bother trying to decode URLs that do
+ not contain at least one '%' sign. It reduces the log noise and
+ a number of unnecessary memory allocations.
+ - In case of SOCKS5 failures, dump the socks response in the log message.
+ - Simplify the signal setup in main().
+ - Streamline socks5_connect() slightly.
+ - In socks5_connect(), require a complete socks response from the server.
+ Previously Privoxy didn't care how much data the server response
+ contained as long as the first two bytes contained the expected
+ values. While at it, shrink the buffer size so Privoxy can't read
+ more than a whole socks response.
+ - In chat(), do not bother to generate a client request in case of
+ direct CONNECT requests. It will not be used anyway.
+ - Reduce server_last_modified()'s stack size.
+ - Shorten get_http_time() by using strftime().
+ - Constify the known_http_methods pointers in unknown_method().
+ - Constify the time_formats pointers in parse_header_time().
+ - Constify the formerly_valid_actions pointers in action_used_to_be_valid().
+ - Introduce a GNUMakefile MAN_PAGE variable that defaults to privoxy.1.
+ The Debian package uses section 8 for the man page and this
+ should simplify the patch.
+ - Deduplicate the INADDR_NONE definition for Solaris by moving it to jbsockets.h
+ - In block_url(), ditch the obsolete workaround for ancient Netscape versions
+ that supposedly couldn't properly deal with status code 403.
+ - Remove a useless NULL pointer check in load_trustfile().
+ - Remove two useless NULL pointer checks in load_one_re_filterfile().
+ - Change url_code_map[] from an array of pointers to an array of arrays
+ It removes an unnecessary layer of indirection and on 64bit system reduces
+ the size of the binary a bit.
+ - Fix various typos. Fixes taken from Debian's 29_typos.dpatch by Roland Rosenfeld.
+ - Add a dok-tidy GNUMakefile target to clean up the messy HTML
+ generated by the other dok targets.
+ - GNUisms in the GNUMakefile have been removed.
+ - Change the HTTP version in static responses to 1.1
+ - Synced config.sub and config.guess with upstream
+ 2011-11-11/386c7218162c145f5f9e1ff7f558a3fbb66c37c5.
+ - Add a dedicated function to parse the values of toggles. Reduces duplicated
+ code in load_config() and provides better error handling. Invalid or missing
+ toggle values are now a fatal error instead of being silently ignored.
+ - Terminate HTML lines in static error messages with \n instead of \r\n.
+ - Simplify cgi_error_unknown() a bit.
+ - In LogPutString(), don't bother looking at pszText when not
+ actually logging anything.
+ - Change ssplit()'s fourth parameter from int to size_t.
+ Fixes a clang complaint.
+ - Add a warning that the statistics currently can't be trusted.
+ Mention Privoxy-Log-Parser's --statistics option as
+ an alternative for the time being.
+ - In rfc2553_connect_to(), start setting cgi->error_message on error.
+ - Change the expected status code returned for http://p.p/die depending
+ on whether or not FEATURE_GRACEFUL_TERMINATION is available.
+ - In cgi_die(), mark the client connection for closing.
+ If the client will fetch the style sheet through another connection
+ it gets the main thread out of the accept() state and should thus
+ trigger the actual shutdown.
+ - Add a proper CGI message for cgi_die().
+ - Don't enforce a logical line length limit in read_config_line().
+ - Slightly refactor server_last_modified() to remove useless gmtime*() calls.
+ - In get_content_type(), also recognize '.jpeg' as JPEG extension.
+ - Add '.png' to the list of recognized file extensions in get_content_type().
+ - In block_url(), consistently use the block reason "Request blocked by Privoxy"
+ In two places the reason was "Request for blocked URL" which hides the
+ fact that the request got blocked by Privoxy and isn't necessarily
+ correct as the block may be due to tags.
+ - In listen_loop(), reload the configuration files after accepting
+ a new connection instead of before.
+ Previously the first connection that arrived after a configuration
+ change would still be handled with the old configuration.
+ - In chat()'s receive-data loop, skip a client socket check if
+ the socket will be written to right away anyway. This can
+ increase the transfer speed for unfiltered content on fast
+ network connections.
+ - The socket timeout is used for SOCKS negotiations as well which
+ previously couldn't timeout.
+ - Don't keep the client connection alive if any configuration file
+ changed since the time the connection came in. This is closer to
+ Privoxy's behaviour before keep-alive support for client connection
+ has been added and also less confusing in general.
+ - Treat all Content-Type header values containing the pattern
+ 'script' as a sign of text. Reported by pribog in #3134970.
+
+- Action file improvements:
+ - Moved the site-specific block pattern section below the one for the
+ generic patterns so for requests that are matched in both, the block
+ reason for the domain is shown which is usually more useful than showing
+ the one for the generic pattern.
+ - Remove -prevent-compression from the fragile alias. It's no longer
+ used anywhere by default and isn't known to break stuff anyway.
+ - Add a (disabled) section to block various Facebook tracking URLs.
+ Reported by Dan Stahlke in #3421764.
+ - Add a (disabled) section to rewrite and redirect click-tracking
+ URLs used on news.google.com.
+ Reported by Dan Stahlke in #3421755.
+ - Unblock linuxcounter.net/.
+ Reported by Dan Stahlke in #3422612.
+ - Block 'www91.intel.com/' which is used by Omniture.
+ Reported by Adam Piggott in #3167370.
+ - Disable the handle-as-empty-doc-returns-ok option and mark it as deprecated.
+ Reminded by tceverling in #2790091.
+ - Add ".ivwbox.de/" to the "Cross-site user tracking" section.
+ Reported by Nettozahler in #3172525.
+ - Unblock and fast-redirect ".awin1.com/.*=http://".
+ Reported by Adam Piggott in #3170921.
+ - Block "b.collective-media.net/".
+ - Widen the Debian popcon exception to "qa.debian.org/popcon".
+ Seen in Debian's 05_default_action.dpatch by Roland Rosenfeld.
+ - Block ".gemius.pl/" which only seems to be used for user tracking.
+ Reported by johnd16 in #3002731. Additional input from Lee and movax.
+ - Disable banners-by-size filters for '.thinkgeek.com/'.
+ The filter only seems to catch pictures of the inventory.
+ - Block requests for 'go.idmnet.bbelements.com/please/showit/'.
+ Reported by kacperdominik in #3372959.
+ - Unblock adainitiative.org/.
+ - Add a fast-redirects exception for '.googleusercontent.com/.*=cache'.
+ - Add a fast-redirects exception for webcache.googleusercontent.com/.
+ - Unblock http://adassier.wordpress.com/ and http://adassier.files.wordpress.com/.
+
+- Filter file improvements:
+ - Let the yahoo filter hide '.ads'.
+ - Let the msn filter hide overlay ads for Facebook 'likes' in search
+ results and elements with the id 's_notf_div'. They only seem to be
+ used to advertise site 'enhancements'.
+ - Let the js-events filter additionally disarm setInterval().
+ Suggested by dg1727 in #3423775.
+
+- Documentation improvements:
+ - Clarify the effect of compiling Privoxy with zlib support.
+ Suggested by dg1727 in #3423782.
+ - Point out that the SourceForge messaging system works like a black
+ hole and should thus not be used to contact individual developers.
+ - Mention some of the problems one can experience when not explicitly
+ configuring an IP addresses as listen address.
+ - Explicitly mention that hostnames can be used instead of IP addresses
+ for the listen-address, that only the first address returned will be
+ used and what happens if the address is invalid.
+ Requested by Calestyo in #3302213.
+
+- Log message improvements:
+ - If only the server connection is kept alive, do not pretend to
+ wait for a new client request.
+ - Remove a superfluous log message in forget_connection().
+ - In chat(), properly report missing server responses as such
+ instead of calling them empty.
+ - In forwarded_connect(), fix a log message nobody should ever see.
+ - Fix a log message in socks5_connect(), a failed write operation
+ was logged as failed read operation.
+ - Let load_one_actions_file() properly complain about a missing
+ '{' at the beginning of the file.
+ Simply stating that a line is invalid isn't particularly helpful.
+ - Do not claim to listen on a socket until Privoxy actually does.
+ Patch submitted by Petr Pisar #3354485
+ - Prevent a duplicated LOG_LEVEL_CLF message when sending out
+ the "no-server-data" response.
+ - Also log the client socket when dropping a connection.
+ - Include the destination host in the 'Request ... marked for
+ blocking. limit-connect{...} doesn't allow CONNECT ...' message
+ Patch submitted by Saperski in #3296250.
+ - Prevent a duplicated log message if none of the resolved IP
+ addresses were reachable.
+ - In connect_to(), do not pretend to retry if forwarded-connect-retries
+ is zero or unset.
+ - When a specified user or group can't be found, put the name in
+ single-quotes when logging it.
+ - In rfc2553_connect_to(), explain getnameinfo() errors better.
+ - Remove a useless log message in chat().
+ - When retrying to connect, also log the maximum number of connection
+ attempts.
+ - Rephrase a log message in compile_dynamic_pcrs_job_list().
+ Divide the error code and its meaning with a colon. Call the pcrs
+ job dynamic and not the filter. Filters may contain dynamic and
+ non-dynamic pcrs jobs at the same time. Only mention the name of
+ the filter or tagger, but don't claim it's a filter when it could
+ be a tagger.
+ - In a fatal error message in load_one_actions_file(), cover both
+ URL and TAG patterns.
+ - In pcrs_strerror(), properly report unknown positive error code
+ values as such. Previously they were handled like 0 (no error).
+ - In compile_dynamic_pcrs_job_list(), also log the actual error code as
+ pcrs_strerror() doesn't handle all errors reported by pcre.
+ - Don't bother trying to continue chatting if the client didn't ask for it.
+ Reduces log noise a bit.
+ - Make two fatal error message in load_one_actions_file() more descriptive.
+ - In cgi_send_user_manual(), log when rejecting a file name due to '/' or '..'.
+ - In load_file(), log a message if opening a file failed.
+ The CGI error message alone isn't too helpful.
+ - In connection_destination_matches(), improve two log messages
+ to help understand why the destinations don't match.
+ - Rephrase a log message in serve(). Client request arrival
+ should be differentiated from closed client connections now.
+ - In serve(), log if a client connection isn't reused due to a
+ configuration file change.
+ - Let mark_server_socket_tainted() always mark the server socket tainted,
+ just don't talk about it in cases where it has no effect. It doesn't change
+ Privoxy's behaviour, but makes understanding the log file easier.
+
+- configure:
+ - Added a --disable-ipv6-support switch for platforms where support
+ is detected but doesn't actually work.
+ - Do not check for the existence of strerror() and memmove() twice
+ - Remove a useless test for setpgrp(2). Privoxy doesn't need it and
+ it can cause problems when cross-compiling.
+ - Rename the --disable-acl-files switch to --disable-acl-support.
+ Since about 2001, ACL directives are specified in the standard
+ config file.
+ - Update the URL of the 'Removing outdated PCRE version after the
+ next stable release' posting. The old URL stopped working after
+ one of SF's recent site "optimizations". Reported by Han Liu.
+
+- Privoxy-Regression-Test:
+ - Added --shuffle-tests option to increase the chances of detection race conditions.
+ - Added a --local-test-file option that allows to use Privoxy-Regression-Test without Privoxy.
+ - Added tests for missing socks4 and socks4a forwarders.
+ - The --privoxy-address option now works with IPv6 addresses containing brackets, too.
+ - Perform limited sanity checks for parameters that are supposed to have numerical values.
+ - Added a --sleep-time option to specify a number of seconds to
+ sleep between tests, defaults to 0.
+ - Disable the range-requests tagger for tests that break if it's enabled.
+ - Log messages use the ISO 8601 date format %Y-%m-%d.
+ - Fix spelling in two error messages.
+ - In the --help output, include a list of supported tests and their default levels.
+ - Adjust the tests to properly deal with FEATURE_TOGGLE being disabled.
+
+- Privoxy-Log-Parser:
+ - Perform limited sanity checks for command line parameters that
+ are supposed to have numerical values.
+ - Implement a --unbreak-lines-only option to try to revert MUA breakage.
+ - Accept and highlight: Added header: Content-Encoding: deflate
+ - Accept and highlight: Compressed content from 29258 to 8630 bytes.
+ - Accept and highlight: Client request arrived in time on socket 21.
+ - Highlight: Didn't receive data in time: a.fsdn.com:443
+ - Accept log messages with ISO 8601 time stamps, too.
+
+- uagen:
+ - Bump generated Firefox version to 8.0.
+ - Only randomize the release date if the new --randomize-release-date
+ option is enabled. Firefox versions after 4 use a fixed date string
+ without meaning.
+
+*** Version 3.0.17 Stable ***
+
+- Fixed last-chunk-detection for responses where the body was small
+ enough to be read with the headers, causing Privoxy to wait for the
+ end of the content until the server closed the connection or the
+ request timed out. Reported by "Karsten" in #3028326.
+- Responses with status code 204 weren't properly detected as body-less
+ like RFC2616 mandates. Like the previous bug, this caused Privoxy to
+ wait for the end of the content until the server closed the connection
+ or the request timed out. Fixes #3022042 and #3025553, reported by a
+ user with no visible name. Most likely also fixes a bunch of other
+ AJAX-related problem reports that got closed in the past due to
+ insufficient information and lack of feedback.
+- Fixed an ACL bug that made it impossible to build a blacklist.
+ Usually the ACL directives are used in a whitelist, which worked
+ as expected, but blacklisting is still useful for public proxies
+ where one only needs to deny known abusers access.
+- Added LOG_LEVEL_RECEIVED to log the not-yet-parsed data read from the
+ network. This should make debugging various parsing issues a lot easier.
+- The IPv6 code is enabled by default on Windows versions that support it.
+ Patch submitted by oCameLo in #2942729.
+- In mingw32 versions, the user.filter file is reachable through the
+ GUI, just like default.filter is. Feature request 3040263.
+- Added the configure option --enable-large-file-support to set a few
+ defines that are required by platforms like GNU/Linux to support files
+ larger then 2GB. Mainly interesting for users without proper logfile
+ management.
+- Logging with "debug 16" no longer stops at the first nul byte which is
+ pretty useless. Non-printable characters are replaced with their hex value
+ so the result can't span multiple lines making parsing them harder then
+ necessary.
+- Privoxy logs when reading an action, filter or trust file.
+- Fixed incorrect regression test markup which caused a test in
+ 3.0.16 to fail while Privoxy itself was working correctly.
+ While Privoxy accepts hide-referer, too, the action name is actually
+ hide-referrer which is also the name used one the final results page,
+ where the test expected the alias.
+
+- CGI interface improvements:
+ - In finish_http_response(), continue to add the 'Connection: close'
+ header if the client connection will not be kept alive.
+ Anonymously pointed out in #2987454.
+ - Apostrophes in block messages no longer cause parse errors
+ when the blocked page is viewed with JavaScript enabled.
+ Reported by dg1727 in #3062296.
+ - Fix a bunch of anchors that used underscores instead of dashes.
+ - Allow to keep the client connection alive after crunching the previous request.
+ Already opened server connections can be kept alive, too.
+ - In cgi_show_url_info(), don't forget to prefix URLs that only contain
+ http:// or https:// in the path. Fixes #2975765 reported by Adam Piggott.
+ - Show the 404 CGI page if cgi_send_user_manual() is called while
+ local user manual delivery is disabled.
+
+- Action file improvements:
+ - Enable user.filter by default. Suggested by David White in #3001830.
+ - Block .sitestat.com/. Reported by johnd16 in #3002725.
+ - Block .atemda.com/. Reported by johnd16 in #3002723.
+ - Block js.adlink.net/. Reported by johnd16 in #3002720.
+ - Block .analytics.yahoo.com/. Reported by johnd16 in #3002713.
+ - Block sb.scorecardresearch.com, too. Reported by dg1727 in #2992652.
+ - Fix problems noticed on Yahoo mail and news pages.
+ - Remove the too broad yahoo section, only keeping the
+ fast-redirects exception as discussed on ijbswa-devel@.
+ - Don't block adesklets.sourceforge.net. Reported in #2974204.
+ - Block chartbeat ping tracking. Reported in #2975895.
+ - Tag CSS and image requests with cautious and medium settings, too.
+ - Don't handle view.atdmt.com as image. It's used for click-throughs
+ so users should be able to "go there anyway".
+ Reported by Adam Piggott in #2975927.
+ - Also let the refresh-tags filter remove invalid refresh tags where
+ the 'url=' part is missing. Anonymously reported in #2986382.
+ While at it, update the description to mention the fact that only
+ refresh tags with refresh times above 9 seconds are covered.
+ - javascript needs to be blocked with +handle-as-empty-document to
+ work around Firefox bug 492459. So move .js blockers from
+ +block{Might be a web-bug.} -handle-as-empty-document to
+ +block{Might be a web-bug.} +handle-as-empty-document.
+ - ijbswa-Feature Requests-3006719 - Block 160x578 Banners.
+ - Block another omniture tracking domain.
+ - Added a range-requests tagger.
+ - Added two sections to get Flickr's Ajax interface working with
+ default pre-settings. If you change the configuration to block
+ cookies by default, you'll need additional exceptions.
+ Reported by Mathias Homann in #3101419 and by Patrick on ijbswa-users@.
+
+- Documentation improvements:
+ - Explicitly mention how to match all URLs.
+ - Consistently recommend socks5 in the Tor FAQ entry and mention
+ its advantage compared to socks4a. Reported by David in #2960129.
+ - Slightly improve the explanation of why filtering may appear
+ slower than it is.
+ - Grammar fixes for the ACL section.
+ - Fixed a link to the 'intercepting' entry and add another one.
+ - Rename the 'Other' section to 'Mailing Lists' and reword it
+ to make it clear that nobody is forced to use the trackers
+ - Note that 'anonymously' posting on the trackers may not always
+ be possible.
+ - Suggest to enable debug 32768 when suspecting parsing problems.
+
+- Privoxy-Log-Parser improvements:
+ - Gather statistics for ressources, methods, and HTTP versions
+ used by the client.
+ - Also gather statistics for blocked and redirected requests.
+ - Provide the percentage of keep-alive offers the client accepted.
+ - Add a --url-statistics-threshold option.
+ - Add a --host-statistics-threshold option to also gather
+ statistics about how many request where made per host.
+ - Fix a bug in handle_loglevel_header() where a 'scan: ' got lost.
+ - Add a --shorten-thread-ids option to replace the thread id with
+ a decimal number.
+ - Accept and ignore: Looks like we got the last chunk together
+ with the server headers. We better stop reading.
+ - Accept and ignore: Continue hack in da house.
+ - Accept and higlight: Rejecting connection from 10.0.0.2.
+ Maximum number of connections reached.
+ - Accept and highlight: Loading actions file: /usr/local/etc/privoxy/default.action
+ - Accept and highlight: Loading filter file: /usr/local/etc/privoxy/default.filter
+ - Accept and highlight: Killed all-caps Host header line: HOST: bestproxydb.com
+ - Accept and highlight: Reducing expected bytes to 0. Marking
+ the server socket tainted after throwing 4 bytes away.
+ - Accept: Merged multiple header lines to: 'X-FORWARDED-PROTO: http X-HOST: 127.0.0.1'
+
+- Code cleanups:
+ - Remove the next member from the client_state struct. Only the main
+ thread needs access to all client states so give it its own struct.
+ - Garbage-collect request_contains_null_bytes().
+ - Ditch redundant code in unload_configfile().
+ - Ditch LogGetURLUnderCursor() which doesn't seem to be used anywhere.
+ - In write_socket(), remove the write-only variable write_len in
+ an ifdef __OS2__ block. Spotted by cppcheck.
+ - In connect_to(), don't declare the variable 'flags' on OS/2 where
+ it isn't used. Spotted by cppcheck.
+ - Limit the scope of various variables. Spotted by cppcheck.
+ - In add_to_iob(), turn an interestingly looking for loop into a
+ boring while loop.
+ - Code cleanup in preparation for external filters.
+ - In listen_loop(), mention the socket on which we accepted the
+ connection, not just the source IP address.
+ - In write_socket(), also log the socket we're writing to.
+ - In log_error(), assert that escaped characters get logged
+ completely or not at all.
+ - In log_error(), assert that ival and sval have reasonable values.
+ There's no reason not to abort() if they don't.
+ - Remove an incorrect cgi_error_unknown() call in a
+ cannot-happen-situation in send_crunch_response().
+ - Clean up white-space in http_response definition and
+ move the crunch_reason to the beginning.
+ - Turn http_response.reason into an enum and rename it
+ to http_response.crunch_reason.
+ - Silence a 'gcc (Debian 4.3.2-1.1) 4.3.2' warning on i686 GNU/Linux.
+ - Fix white-space in a log message in remove_chunked_transfer_coding().
+ While at it, add a note that the message doesn't seem to
+ be entirely correct and should be improved later on.
+
+- GNUmakefile improvements:
+ - Use $(SSH) instead of ssh, so one only needs to specify a username once.
+ - Removed references to the action feedback thingy that hasn't been
+ working for years.
+ - Consistently use shell.sourceforge.net instead of shell.sf.net so
+ one doesn't need to check server fingerprints twice.
+ - Removed GNUisms in the webserver and webactions targets so they
+ work with standard tar.
+
+*** Version 3.0.16 Stable ***
+
+- Added the config file option handle-as-empty-doc-returns-ok to
+ work around Firefox bug #492459, which causes Firefox to hang
+ if JavaScripts are blocked in certain situations. The option is
+ enabled in the default config file.
+- Added the config file option default-server-timeout to control the
+ assumed default server timeout. Since Privoxy no longer returns
+ an error message for connection resets on reused client connections,
+ assuming larger server timeout values appears to actually work
+ pretty well as long as connections aren't shared.
+- Added optional support for FreeBSD's accf_http(9). Use the
+ configure option --enable-accept-filter to enable it.
+- Added fancier Privoxy icons for win32. Contributed by Jeff H.
+- In daemon mode, fd 0, 1 and 2 are bound to /dev/null.
+- Resolve localhost using whatever address family the operating
+ system feels like. Previous betas would try to use IPv4 as this
+ is what most users expect, but this didn't work reliably on
+ GNU/Linux systems.
+- In the action lists on CGI pages, actions and their parameters are
+ no longer separated with a space. The action file parser doesn't
+ actually allow this and will throw an invalid syntax error if actions
+ and parameters in the action files are separated. Not adding the
+ spaces means copy and pasting CGI output into the action files works.
+- The default keep-alive timeout has been reduced to 5 seconds to work
+ around hangs in clients that treat the proxy like any other host and
+ stop allowing any new connections if the "maximum number of
+ connections per host" is reached.
+- Several webbug URLs that look like they are leading to images are now
+ blocked as image instead of empty documents. Doing the latter causes
+ WebKit-based clients to show a "missing image" icon which may mess up
+ the layout.
+- The no-such-domain template is used for DNS resolution
+ problems with FEATURE_IPV6_SUPPORT enabled. Previously the
+ connect-failed template was used. Reported by 'zebul666'.
+- Accepts quoted expiration dates even though RFC 2109 10.1.2
+ doesn't seem to allow them. Reported anonymously.
+- Don't try to forget connections if connection sharing is disabled.
+ This wasn't a real problem but caused an unnecessary log message.
+- The still undocumented --enable-extended-host-patterns configure
+ option has a better description.
+- Fixed an error message that would claim a write to the server
+ failed when actually writing to the client failed.
+- Log the crunch reason before trying to write to the client.
+ The log is easier to read that way.
+- Several log messages about client connections also mention
+ the socket number.
+- handle-as-empty-document no longer depends on the image blocking
+ code being enabled.
+- Privoxy-Log-Parser is roughly 40% faster in highlighting mode.
+- uagen, a Firefox User-Agent generator for Privoxy and Mozilla
+ browsers has been imported and is available in the tarball's
+ tools directory.
+- The scripts in the tools directory treat unknown parameters
+ as fatal errors.
+
+*** Version 3.0.15 beta ***
+
+- In case of missing server data, no error message is send to the
+ client if the request arrived on a reused connection. The client
+ is then supposed to silently retry the request without bothering
+ the user. This should significantly reduce the frequency of the
+ "No server or forwarder data received" error message many users
+ reported.
+- More reliable detection of prematurely closed client sockets
+ with keep-alive enabled.
+- FEATURE_CONNECTION_KEEP_ALIVE is decoupled from
+ FEATURE_CONNECTION_SHARING and now available on
+ all platforms.
+- Improved handling of POST requests on reused connections.
+ Should fix problems with stalled connections after submitting
+ form data with some browser configurations.
+- Fixed various latency calculation issues.
+- Allows the client to pass NTLM authentication requests to a
+ forwarding proxy. This was already assumed and hinted to work
+ in 3.0.13 beta but actually didn't. Now it's confirmed to work
+ with IE, Firefox and Chrome.
+ Thanks to Francois Botha and Wan-Teh Chang
+- Fixed a calculation problem if receiving the server headers
+ takes more than two reads, that could cause Privoxy to terminate
+ the connection prematurely. Reported by Oliver.
+- Compiles again on platforms such as OpenBSD and systems
+ using earlier glibc version that don't support AI_ADDRCONFIG.
+ Anonymously submitted in #2872591.
+- A bunch of MS VC project files and Suse and Redhat RPM spec
+ files have been removed as they were no longer maintained for
+ quite some time.
+- Overly long action lines are properly rejected with a proper
+ error message. Previously they would be either rejected as
+ invalid or cause a core dump through abort().
+- Already timed-out connections are no longer temporarily remembered.
+ They weren't reused anyway, but wasted a socket slot.
+- len refers to the number of bytes actually read which might
+ differ from the ones received. Adjust log messages accordingly.
+- The optional JavaScript on the CGI page uses encodeURIComponent()
+ instead of escape() which doesn't encode all characters that matter.
+ Anonymously reported in #2832722.
+- Fix gcc45 warnings in decompress_iob().
+- Various log message improvements.
+- Privoxy-Regression-Test supports redirect tests.
+- Privoxy-Log-Parser can gather some connection statistics.
+
+*** Version 3.0.14 beta ***
+
+- The latency is taken into account when evaluating whether or not to
+ reuse a connection. This should significantly reduce the number of
+ connections problems several users reported.
+- If the server doesn't specify how long the connection stays alive,
+ Privoxy errs on the safe side of caution and assumes it's only a second.
+- The error pages for connection timeouts or missing server data use a
+ Last-Modified date in the past. Retry attempts are detected and Privoxy
+ removes the If-Modified-Since header to prevent the server from responding
+ with status code 304 in which case the client would reuse the error message.
+- Setting keep-alive-timeout to 0 disables keep-alive support. Previously
+ Privoxy would claim to allow persistence but not reuse the connection.
+- Pipelined requests are less likely to be mistaken for the request
+ body of the previous request. Note that Privoxy still has no real
+ pipeline support and will either serialize pipelined requests or
+ drop them in which case the client has to resent them.
+- Fixed a crash on some Windows versions when header randomization
+ is enabled and the date couldn't be parsed.
+- Privoxy's keep-alive timeout for the current connection is reduced
+ to the one specified in the client's Keep-Alive header.
+- For HTTP/1.1 requests, Privoxy implies keep-alive support by not
+ setting any Connection header instead of using 'Connection: keep-alive'.
+- If the socket isn't reusable, Privoxy doesn't temporarily waste
+ a socket slot to remember the connection.
+- If keep-alive support is disabled but compiled in, the client's
+ Keep-Alive header is removed.
+- Fixed a bug on mingw32 where downloading large files failed if
+ keep-alive support was enabled.
+- Fixed a bug that (at least theoretically) could cause log
+ timestamps to be occasionally off by about a second.
+- No Proxy-Connection header if added if there already is one.
+- The configure script respects the $PATH variable when searching
+ for groups and id.
+
+*** Version 3.0.13 beta ***
+
+- Added IPv6 support. Thanks to Petr Pisar who not only provided
+ the initial patch but also helped a lot with the integration.
+- Added client-side keep-alive support.
+- The connection sharing code is only used if the connection-sharing
+ option is enabled.
+- The max-client-connections option has been added to restrict
+ the number of client connections below a value enforced by
+ the operating system.
+- Fixed a regression reintroduced in 3.0.12 that could cause
+ crashes on mingw32 if header date randomization was enabled.
+- Compressed content with extra fields couldn't be decompressed
+ and would get passed to the client unfiltered. This problem
+ has only be detected through statical analysis with clang as
+ nobody seems to be using extra fields anyway.
+- If the server resets the Connection after sending only the headers
+ Privoxy forwards what it got to the client. Previously Privoxy
+ would deliver an error message instead.
+- Error messages in case of connection timeouts use the right
+ HTTP status code.
+- If spawning a child to handle a request fails, the client
+ gets an error message and Privoxy continues to listen for
+ new requests right away.
+- The error messages in case of server-connection timeouts or
+ prematurely closed server connections are now template-based.
+- If zlib support isn't compiled in, Privoxy no longer tries to
+ filter compressed content unless explicitly asked to do so.
+- In case of connections that are denied based on ACL directives,
+ the memory used for the client IP is no longer leaked.
+- Fixed another small memory leak if the client request times out
+ while waiting for client headers other than the request line.
+- The client socket is kept open until the server socket has
+ been marked as unused. This should increase the chances that
+ the still-open connection will be reused for the client's next
+ request to the same destination. Note that this only matters
+ if connection-sharing is enabled.
+- A TODO list has been added to the source tarball to give potential
+ volunteers a better idea of what the current goals are. Donations
+ are still welcome too: https://www.privoxy.org/faq/general.html#DONATE
+
+*** Version 3.0.12 ***
+
+- The socket-timeout option now also works on platforms whose
+ select() implementation modifies the timeout structure.
+ Previously the timeout was triggered even if the connection
+ didn't stall. Reported by cyberpatrol.
+- The Connection: keep-alive code properly deals with files
+ larger than 2GB. Previously the connection was closed too
+ early.
+- The content length for files above 2GB is logged correctly.
+- The user-manual directive on the show-status page links to
+ the documentation location specified with the directive,
+ not to the Privoxy website.
+- When running in daemon mode, Privoxy doesn't log anything
+ to the console unless there are errors before the logfile
+ has been opened.
+- The show-status page prints warnings about invalid directives
+ on the same line as the directives themselves.
+- Fixed several justified (but harmless) compiler warnings,
+ mostly on 64 bit platforms.
+- The mingw32 version explicitly requests the default charset
+ to prevent display problems with some fonts available on more
+ recent Windows versions. Patch by Burberry.
+- The mingw32 version uses the Privoxy icon in the alt-tab
+ windows. Patch by Burberry.
+- The timestamp and the thread id is omitted in the "Fatal error"
+ message box on mingw32.
+- Fixed two related mingw32-only buffer overflows. Triggering
+ them required control over the configuration file, therefore
+ this isn't seen as a security issue.
+- In verbose mode, or if the new option --show-skipped-tests
+ is used, Privoxy-Regression-Test logs skipped tests and the
+ skip reason.
+
+*** Version 3.0.11 ***
+
+- On most platforms, outgoing connections can be kept alive and
+ reused if the server supports it. Whether or not this improves
+ things depends on the connection.
+- When dropping privileges, membership in supplementary groups
+ is given up as well. Not doing that can lead to Privoxy running
+ with more rights than necessary and violates the principle of
+ least privilege. Users of the --user option are advised to update.
+ Thanks to Matthias Drochner for reporting the problem,
+ providing the initial patch and testing the final version.
+- Passing invalid users or groups with the --user option
+ didn't lead to program exit. Regression introduced in 3.0.7.
+- The match all section has been moved from default.action
+ to a new file called match-all.action. As a result the
+ default.action no longer needs to be touched by the user
+ and can be safely overwritten by updates.
+- The standard.action file has been removed. Its content
+ is now part of the default.action file.
+- In some situations the logged content length was slightly too low.
+- Crunched requests are logged with their own log level.
+ If you used "debug 1" in the past, you'll probably want
+ to additionally enable "debug 1024", otherwise only passed
+ requests will be logged. If you only care about crunched
+ requests, simply replace "debug 1" with "debug 1024".
+- The crunch reason has been moved to the beginning of the
+ crunch message. For HTTP URLs, the protocol is logged as well.
+- Log messages are shortened by printing the thread id on its
+ own (as opposed to putting it inside the string "Privoxy()").
+- The config option socket-timeout has been added to control
+ the time Privoxy waits for data to arrive on a socket.
+- Support for remote toggling is controlled by the configure
+ option --disable-toggle only. In previous versions it also
+ depended on the action editor and thus configuring with the
+ --disable-editor option would disable remote toggling support
+ as well.
+- Requests with invalid HTTP versions are rejected.
+- The template symbol @date@ can be used to include a date(1)-like
+ time string. Initial patch submitted by Endre Szabo.
+- Responses from shoutcast servers are accepted again.
+ Problem reported and fix suggested by Stefan.
+- The hide-forwarded-for-headers action has been replaced with
+ the change-x-forwarded-for{} action which can also be used to
+ add X-Forwarded-For headers. The latter functionality already
+ existed in Privoxy versions prior to 3.0.7 but has been removed
+ as it was often used unintentionally (by not using the
+ hide-forwarded-for-headers action).
+- A "clear log" view option was added to the mingw32 version
+ to clear out all of the lines in the Privoxy log window.
+ Based on a patch submitted by T Ford.
+- The mingw32 version uses "critical sections" now, which prevents
+ log message corruption under load. As a side effect, the
+ "no thread-safe PRNG" warning could be removed as well.
+- The mingw32 version's task bar icon is crossed out and
+ the color changed to gray if Privoxy is toggled off.
+
+*** Version 3.0.10 ***
+
+- Ordinary configuration file changes no longer cause program
+ termination on OS/2 if the name of the logfile hasn't been
+ changed as well. This regression probably crept in with the
+ logging improvements in 3.0.7. Reported by Maynard.
+- The img-reorder filter is less likely to mess up JavaScript code in
+ img tags. Problem and solution reported by Glenn Washburn in #2014552.
+- The source tar ball now includes Privoxy-Log-Parser,
+ a syntax-highlighter for Privoxy logs. For fancy screenshots see:
+ http://www.fabiankeil.de/sourcecode/privoxy-log-parser/
+ Documentation is available through perldoc(1).
+
+*** Version 3.0.9 beta ***
+
+- Added SOCKS5 support (with address resolution done by
+ the SOCKS5 server). Patch provided by Eric M. Hopper.
+- The "blocked" CGI pages include a block reason that was
+ provided as argument to the last-applying block action.
+- If enable-edit-actions is disabled (the default since 3.0.7 beta)
+ the show-status page hides the edit buttons and explains why.
+ Previously the user would get the "this feature has been disabled"
+ message after using the edit button.
+- Forbidden CONNECT requests are treated like blocks by default.
+ The now-pointless treat-forbidden-connects-like-blocks action
+ has been removed.
+- Not enabling limit-connect now allows CONNECT requests to all ports.
+ In previous versions it would only allow CONNECT requests to port 443.
+ Use +limit-connect{443} if you think you need the old default behaviour.
+- The CGI editor gets turned off after three edit requests with invalid
+ file modification timestamps. This makes life harder for attackers
+ who can leverage browser bugs to send fake Referers and intend to
+ brute-force edit URLs.
+- Action settings for multiple patterns in the same section are
+ shared in memory. As a result these sections take up less space
+ (and are loaded slightly faster). Problem reported by Franz Schwartau.
+- Linear white space in HTTP headers will be normalized to single
+ spaces before parsing the header's content, headers split across
+ multiple lines get merged first. This should prevent problems like:
+ * letting the session-cookies-only action slip
+ some Cookies through unmodified,
+ * only suppressing the first line of a header,
+ thus creating an invalid one, and
+ * to incorrectly block headers with valid timestamps
+ that weren't properly recognized.
+ Headers that could trigger these problems are unlikely to appear
+ in "normal" web traffic, but could be intentionally generated to
+ fool some of Privoxy's header parsers.
+- Host information is gathered outside the main thread so it's less
+ likely to delay other incoming connections if the host is misconfigured.
+- New config option "hostname" to use a hostname other than
+ the one returned by the operating system. Useful to speed-up responses
+ for CGI requests on misconfigured systems. Requested by Max Khon.
+- The CGI editor supports the "disable all filters of this type"
+ directives "-client-header-filter", "-server-header-filter",
+ "-client-header-tagger" and "-server-header-tagger".
+- Fixed false-positives with the link-by-url filter and URLs that
+ contain the pattern "/jump/".
+- The less-download-windows filter no longer messes
+ "Content-Type: application/x-shockwave-flash" headers up.
+- In the show-url-info page's "Final results" section active and
+ inactive actions are listed separately. Patch provided by Lee.
+- The GNUmakefile supports the DESTDIR variable. Patch for
+ the install target submitted by Radoslaw Zielinski.
+- Embedding the content of configuration files in the show-status
+ page is significantly faster now. For a largish action file (1 MB)
+ a speedup of about 2450 times has been measured. This is mostly
+ interesting if you are using large action files or regularly use
+ Privoxy-Regression-Test while running Privoxy through Valgrind,
+ for stock configuration files it doesn't really matter.
+- If zlib support is unavailable and there are content
+ filters active but the prevent-compression action is disabled,
+ the show-url-info page includes a warning that compression
+ might prevent filtering.
+- The show-url-info page provides an OpenSearch Description that
+ allows to access the page through browser search plugins.
+- Custom client-header filters that rewrite the request line
+ incorrectly no longer cause Privoxy to crash. Reported by din_a4.
+- The obsolete kill-popups action has been removed as the
+ PCRS-based popup filters can do the same and are slightly
+ less unreliable.
+- The inspect-jpegs action has been removed.
+- The send-wafer and send-vanilla-wafer actions have been removed.
+ They weren't particular useful and their behaviour could be emulated
+ with add-header anyway.
+- Privoxy-Regression-Test has been significantly improved.
+- Most sections in the default.action file contain tests for
+ Privoxy-Regression-Test to verify that they are working as intended.
+- Parts of Privoxy have been refactored to increase maintainability.
+- Building with zlib (if available) is done by default.
+
+*** Version 3.0.8 ***
+
+- Fixed a small memory leak when listen-address only specifies the port.
+- The source tar balls now include Privoxy-Regression-Test which
+ (upon other things) can be used to automatically detect some
+ packaging problems. Packagers are welcome to give it a try.
+- Reverted a change in 3.0.7 that caused path patterns to be checked
+ even if the host pattern match already failed. While this doesn't
+ noticeable affect the performance, it makes it less likely to run
+ out of stack space with overly-complex path patterns the user might
+ have added.
+- Updated the msn, yahoo and google filters to work as advertised again.
+- The warning message shown by the show-status CGI page is easier to
+ understand. Previously it wasn't clear that the error message
+ is shown below the invalid directive. (Reported by Lee)
+- When regenerating Content-Disposition headers the more common
+ spelling is used for the name. Previously it was written without caps.
+- Less confusing log message if the content type isn't overwritten
+ because force-text-type wasn't used but the old type doesn't look
+ like content that would be filtered normally.
+- Better log messages if the user tries to execute filters that
+ don't exist.
+- Treat the non-standard Request-Range headers like standard range
+ headers and suppress them if content filtering is enabled.
+- Prevent the log messages for CONNECT requests to unacceptable
+ ports from printing the limit-connect argument as [null] if
+ limit-connect hasn't been explicitly enabled.
+- Don't disable the mingw32 log window if the logfile directive
+ isn't used. While it was an intentional change in 3.0.7 at least
+ one user perceived it as a regression and the same effect can
+ be achieved by disabling all debug directives.
+- Fixed two minor problems related to the win32 build process: a css
+ file was not being in the installer and the trustfile comment in the
+ config.txt referenced a nonexisting file
+- Minor documentation fixes.
+
+*** Version 3.0.7 beta ***
+
+- Added zlib support to filter content with gzip and deflate
+ encoding. (Patch provided by Wil Mahan)
+- Dedicated filters and actions are used for header filtering.
+ "filter-client-headers" and "filter-client-headers" are no longer
+ supported, use server-header-filter{} and client-header-filter{}
+ instead.
+- Tags can be used to change actions based on HTTP headers.
+- New server-header filter: less-download-windows.
+- New client-header taggers: css-requests, image-requests,
+ client-ip-address, http-method, allow-post, complete-url,
+ user-agent and privoxy-control.
+- New server-header taggers: content-type and privoxy-control.
+- The forward-override{} action allows to change the forwarding
+ settings through the action files, for example based on client
+ headers like the User-Agent, or the request origin.
+- Socks errors are no longer handled by the CGI page for
+ DNS resolution failures.
+- CGI pages use favicons to signal whether they are error
+ or control pages. This is useful if you rely heavily on
+ browser tabs.
+- The show-url-info CGI page shows the forwarding settings.
+- "Crunch!" log messages (used when Privoxy answers requests
+ by itself) now also contain the reason.
+- Allow to rewrite the request destination behind the client's back.
+- Fix socks requests on big-endian platforms. Patch provided by Song Weijia.
+- Fixes possible deadlocks and crashes on OpenBSD.
+ Patch provided by Ralf Horstmann.
+- The CGI action editor allows to edit actionfiles with previously
+ forbidden characters like dots.
+- New trust entries are saved with a comment that contains the
+ trusted referring URL (Suggested by Daniel Griscom).
+- Filter descriptions are HTML encoded automatically.
+- New config option "split-large-forms" to work
+ around a browser bug that caused IE6 and IE7 to ignore
+ the Submit button on the edit-actions-for-url CGI page.
+- New config option "allow-cgi-request-crunching" to allow
+ requests for Privoxy's CGI pages to be blocked, redirected
+ or (un)trusted like ordinary requests.
+- Empty filter files no longer interrupt the filtering process
+ prematurely and are correctly listed on the show-status CGI page.
+- New config option "accept-intercepted-requests" to combine
+ Privoxy with any packet filter to build an intercepting proxy
+ for HTTP/1.1 requests (and for HTTP/1.0 requests with Host header set).
+- fast-redirects{} catch redirects to https URLs as well.
+- redirect{s@foo@bar@} can be used to redirect to a rewritten
+ version of the original URL.
+- Trap unsupported gopher proxy requests.
+- Fixed a bug in the User Manual delivery on Windows
+ (mingw32 only). Images now show up correctly and HTML
+ pages are no longer padded with garbage data.
+- Fixed several minor memory leaks, most of them discovered with Valgrind.
+- Only unlink the pidfile if it's actually used.
+- Retries after connection problems with forced requests
+ aren't blocked again.
+- On Unix SIGABRT causes a core dump as expected and is no
+ longer treated as normal shutdown signal.
+- The "access denied" CGI page is more descriptive and
+ allows retries to circumvent the referrer check.
+- Updated PCRS to handle unexpected PCRE errors properly.
+ Fixed crashes that could occur if Privoxy was build
+ with external PCRE versions newer than Privoxy's internal
+ one. (Reported by Chung-chieh Shan)
+- Fixed crashes with null bytes in PCRS replacement strings
+ (Patch provided by Felix Gröbert).
+- Fixed crashes with header time randomization on mingw32.
+- The CGI style sheet is no longer delivered if the referring
+ page isn't a Privoxy CGI page. This prevents a JavaScript-based
+ Privoxy detection "attack". Note that detecting Privoxy is
+ still possible through other ways and Privoxy was never intended
+ to be invisible anyway.
+- Added support for AmigaOS 4, fixed build for AmigaOS 3.x.
+- The show-url-info CGI page displays a warning if Privoxy
+ is currently toggled off.
+- The show-status CGI page suppresses the edit button
+ for action files if Privoxy has no write access.
+- Most CGI error pages react properly to HEAD requests.
+- Requests with RFC 3253 HTTP methods (used by Subversion)
+ are accepted. (Patch provided by Petr Kadlec)
+- New config option "templdir" to change the location
+ of the CGI templates to make sure customized templates
+ aren't "updated".
+- Better handling of "HTTP/1.1 100 Continue" responses.
+- The background of the PNG pattern is transparent.
+- Fixed XML syntax errors caused by banners-by-size and banners-by-url.
+- Fixed crashes and possible action file corruptions
+ when lines containing hashes are written through the CGI editor.
+- Supports dynamic filters which can contain variables.
+- Supports tags to change the actions based on client or server headers.
+- Incorrect actions are logged before program termination.
+- The "actionsfile" syntax in the configuration file is consistent
+ with the rest of the configuration options and requires the
+ whole file name. This is an incompatible change, if you use
+ an old configuration file you might have to append ".action"
+ to your "actionsfile" directives.
+- With the configuration file option "enforce-blocks" the
+ "go there anyway" mechanism can be disabled without recompiling
+ Privoxy.
+- More precise error messages in case of incorrect acl syntax.
+- Logs a warning if filtering is enabled but impossible due
+ to lack of zlib support or use of the prevent-compression action.
+- Less noisy handling of Cookie:" and "Connection:" headers.
+- Improved error messages in case of connection problems.
+- Fix a command-line-parsing bug that was introduced before 3.0.5
+ beta and caused Privoxy to treat the last argument as configuration
+ file if no configuration file was specified.
+- Treat unknown command line options as fatal errors instead
+ of silently ignoring them.
+- Use string functions with length checks more often.
+- Don't log CONNECT requests twice.
+- Allow to log the source address for ACL-related connection drops.
+- Don't ignore applying filters if the server didn't
+ specify a Content-Type. Bug reported by Amuro Namie.
+- Rejected CONNECT requests are logged with log level info
+ (enabled by default) and the reason for the block.
+- New command line option "--pre-chroot-nslookup hostname" to
+ intialize the resolver library before chroot'ing. On some systems this
+ reduces the number of files that must be copied into the chroot tree.
+ (Patch provided by Stephen Gildea)
+- Fix a long-standing memory corruption bug that could cause
+ Privoxy to overwrite a single byte in memory it didn't explicitly
+ allocate (but that probably was allocated anyway due to bucket size).
+- Send template-based CGI pages as HTTP/1.1 unless the client
+ asked for HTTP/1.0.
+- Let the first line in connection established responses
+ end in \r\n as required by RFC1945. Reported by Bert van Leeuwen.
+- If no log file has been specified, disable logging instead of logging
+ to stderr.
+- Don't block stderr when in daemon mode.
+- Ignore missing zero-chunks when filtering chunk-encoded content.
+ Earlier Privoxy versions would buffer and then forward the content
+ unmodified which caused some browsers to simply show empty pages.
+- Fix double free in cgi_edit_actions_list(). Reported by Venustech AD-LAB.
+- The code to add X-Forwarded-For headers when the hide-forwarded-for-headers
+ action isn't being used has been removed.
+- Fixed trustfile feature which previously didn't work without FEATURE_TOGGLE.
+ Reported by Lee.
+- Minor code clean-ups, filter and action file updates.
+ (Some of them reported by Davide Alberani, Markus Elfring,
+ Stefan Huehner and Adam Piggott)
+
+*** Version 3.0.6 ***
+
+- New content filters: no-ping, google, msn, yahoo and blogspot.
+- New header filters: x-httpd-php-to-html, html-to-xml, xml-to-html
+ and hide-tor-exit-notation.
+- The special header "X-Filter: No" now disables header filtering as well.
+- Improved the filters img-reorder, js-annoyances, webbugs,
+ banners-by-size, banners-by-link and ie-exploits to make them
+ less likely to break anything.
+- Removed outdated URL patterns in default.action and added new ones.
+- Added redirection from http://p.p/user-manual to http://p.p/user-manual/
+- Changed webinterface default values for hide-user-agent, hide-referrer
+ and set-image-blocker.
+
+*** Version 3.0.5 beta ***
+
+- Windows version can be installed/started as a service.
+- Windows icon stays blue when Privoxy is idle, green when busy.
+- Integrated Fabian Keil's extensive patch. See:
+ http://www.fabiankeil.de/sourcecode/privoxy/. Includes the
+ following new or significantly improved actions (among many
+ other improvements):
+
+ content-type-overwrite{}
+ crunch-client-header{string}
+ crunch-if-none-match
+ crunch-server-header{string}
+ fast-redirects{check-decoded-url}
+ filter-client-headers
+ filter-server-headers
+ force-text-mode
+ handle-as-empty-document
+ hide-accept-language{}
+ hide-content-disposition{}
+ hide-if-modified-since
+ hide-referrer{conditional-block}
+ overwrite-last-modified{}
+ redirect{URL}
+ treat-forbidden-connects-like-blocks
+
+- Standard-compliant clients are prevented from displaying cached

To see command-line options, run "./configure --help".
This is my first ever autoconf script, so it has some rough edges
(how PCRE is handled is the roughest).
