ChangeLog for Privoxy
--------------------------------------------------------------------
+*** Version 3.0.30 UNRELEASED ***
+
+- Bug fixes:
+ - Check the actual URL for redirects when https inspecting requests.
+ Previously Privoxy would only check the path which resulted in
+ rewrite results being rejected as invalid URLs.
+ Reported by withoutname in #1736.
+ - Let the hide-referrer code tolerate Referer headers with https:// URLs.
+ Previously they would always be treated like a changed host.
+ - Use the https headers if the show-request handler is reached through
+ https://. Previously Privoxy would use the http headers which
+ may be empty on a reused connection.
+ - Make CGI_PREFIX protocol-relative when building with FEATURE_HTTPS_INSPECTION.
+ This unbreaks (at least) https://config.privoxy.org/client-tags whose
+ buttons would previously use a http:// URL resulting in browser warnings.
+ - Support using https-inspection and client-header-order at the same time.
+ Privously Privoxy would crash.
+ Reported by: Kai Raven
+ - Properly reject rewrites from http to https as they currently
+ aren't supported. Previously Privoxy would wait for the client
+ to establish an encrypted connection which obviously would not happen.
+
+- General improvements:
+ - Allow to rewrite the request destination for https-intercepted
+ requests behind the client's back. The documentation already sort
+ of claimed that it was supported by not especially mentioning that
+ it didn't work for https-inspected requests.
+ Fixes SF bug #923 reported by withoutname.
+ - Add support for filtering client request bodies by using
+ CLIENT-BODY-FILTER filters which can be enabled with the
+ client-body-filter action.
+ Patch submitted by Maxim Antonov.
+ Sponsored by: Robert Klemme
+ - Add the new action suppress-tag{} which can be used to prevent
+ a tagger from adding a tag. Patch submitted by Maxim Antonov.
+ Sponsored by: Robert Klemme
+ - Gracefully handle existing website keys without matching certificates.
+ This can happen if Privoxy was previously running with an invalid
+ TLS configuration that didn't allow it to create a certificate.
+ - Recycle debug bit 4 for Tagging-related messages.
+ - Improve the message shown when the client-tags CGI page
+ is requested with no tags configured.
+ - Shorten the 'donate' and 'participate' links used by templates
+ using redirects. Currently the redirects lead to the FAQ entries
+ but in the future we may want to relocate the content and using
+ redirects makes this more convenient.
+ - Log an error when a PCRE-HOST-PATTERN is used with
+ FEATURE_PCRE_HOST_PATTERNS disabled. Don't treat this a
+ fatal error so the regression tests can be used with and
+ without FEATURE_PCRE_HOST_PATTERNS.
+ - The code compiles with older C compilers again.
+ - Check the chdir() return code to fix a compiler warning.
+ - Let the crude-parental filter insert a link to Privoxy's webinterface.
+ - Remove the packages feed from the source tarball.
+ It's usually out of date when the source tarball is generated
+ for the release.
+ - Fix harmless compiler warnings from GCC9 with -D_FORTIFY_SOURCE=2.
+ - windows: Remove obsolete '$(DEST)/doc/images' target.
+ - windows: Install the images referenced in the user manual.
+ - Remove obsolete 'gnu_regex.@OBJEXT@' target.
+ - When installing from the GNUMAkefile, don't create an 'images'
+ directory which is no longer used. The images were relocated to
+ the user-manual directory years ago.
+ - Add new FEATURES to the show-status page and resort list.
+ - OpenSSL create_client_ssl_connection(): Remove unused variable.
+ - Update bug tracker URL in cgi_error_unknown().
+ - Properly deal with host certificates without keys and keys without
+ host certificate which may be left over from a previous Privoxy run
+ with incorrect configuration.
+ - Saved a couple of memory allocations when sorting client headers.
+ - Improved a couple of error messages.
+ - Saved memory allocations when using OpenSSL and checking if a
+ key already exists.
+ - The configure script will bail out if OpenSSL and mbedTLS are
+ enabled at the same time.
+ - Log a message right before exiting gracefully.
+
+- Action file improvements:
+ - Block requests to eu-tlp03.kameleoon.com/.
+ - Unblock metrics.sr.ht/.
+ - Disable fast-redirects for .fsf.org/.
+ - Disable fast-redirects for .gravater.com/.
+ - Disable fast-redirects for .ksta.de/
+ - Block requests to tag.crsspxl.com/.
+ - Block requests to analytics.slashdotmedia.com/.
+ - Block requests to ml314.com/.
+ - Block requests to .adroll.com/.
+ - Block requests to fastlane.rubiconproject.com/.
+ - Block requests to api.theadex.com/
+ - Block requests to ih.adscale.de/
+ - Block requests to .s400.meetrics.net/
+ - Block requests for pp.lp4.io/
+
+- Filter file improvements:
+ - Added new 'allow-autocompletion' filter which changes
+ autocomplete="off" to "on" on input fields to allow autocompletion.
+ Requested by Jamie Zawinski in #370.
+ Filter based on a submission by Aaron Linville.
+ - Added an imdb filter.
+ - Added a sourceforge filter that reduces the amount of ads
+ for proprietary software.
+ - Added a github filter that removes the annoying "Sign-Up"
+ banner and the Cookie disclaimer.
+
+- privoxy-log-parser:
+ - Highlight 'Rewritten request line results in downgrade to http'.
+ - Highlight 'Rewrite detected: ...' messages again.
+ - Add a handler for tagging messages.
+ - Bump version to 0.9.2.
+ - Properly deal with 'Certificate error' crunches
+ Previously the error description was highlighted as 'host'.
+ - Highlight: 'Flushed 3153 bytes of request body'
+ - Highlight 'The last 12078 bytes of the request body have been read'
+ - Highlight 'Sending data on socket 33 over TLS/SSL failed: ...'
+ - Log truncated LOG_LEVEL_CLF messages more gracefully
+ and note that the statistics will be inprecise.
+
+- privoxy-regression-test:
+ - Use http://127.0.0.1:8118/ as default privoxy address
+ unless http_proxy is set through the environment.
+ - Add a --privoxy-cgi-prefix option that specifies the prefix
+ to use when building URLs that are supposed to reach Privoxy's
+ CGI interface. If it's not set, http://p.p/ is used, which is
+ supposed to work with the default Privoxy configuration.
+ If Privoxy has been built with FEATURE_HTTPS_INSPECTION enabled,
+ and if https inspection is activated with the +https-inspection
+ action, this option can be used with "https://p.p/" provided the
+ system running Privoxy-Regression-Test has been configured to
+ trust the certificate used by Privoxy.
+ Note that there are currently two tests in the official
+ regression-tests.action file that are expected to fail
+ when using "https://p.p/" as privoxy-cgi-prefix.
+ - Skip the connection-established response in get_status_code()
+ when looking for the status code with a CGI prefix
+ that starts with https://. We care about the status code
+ sent by the impersonated web server.
+ - Use --proxy-header when using a CGI prefix with https://
+ and a "Host:" header.
+ - Allow '|' in tokens and values to allow tag patterns like
+ "TAG:^(application|text)/(x-)?javascript$".
+ - When get_cgi_page_or_else() fails, include the URL of the
+ requested page in the log message.
+ - privoxy-regression-test: Bump version to 0.7.2
+
+- uagen:
+ - Update example output.
+ - Recommend the use of the https-inspection action in the documentation.
+ - Upgrade a couple of URLs to https://.
+ - Add ElectroBSD to the list of operating systems.
+ - Bump generated Firefox version to 78 (ESR).
+ - Bump version to 1.2.2.
+
+ - User Documentation:
+ - Remove reference to 'How to Report Bugs Effectively'.
+ It was only rendered as text without URL in the README anyway
+ and there's no indication that users read it ...
+ - Let the dok-readme target fix the location embedded into the
+ README file. This used to be done by CVS but since the git migration
+ it has to be done through other means.
+ - Remove 'experimental' warning for client-specific-tag-related directives.
+ They seem to work reliably and there is no obvious reason
+ why we would change the syntax in the near future.
+ - Describe how to check if Privoxy has been built with
+ FEATURE_HTTPS_INSPECTION.
+ - Add a link to the trusted-cas-file documentation
+ that explains how the user can create the file herself.
+ - Don't explicitly mention the license for the code coming from
+ 'Anonymous Coders' and Junkbusters. It's obviously licensed under
+ the GNU GPL like the rest of Privoxy or we wouldn't be allowed to
+ distribute it.
+ - Update the +hide-user-agent example with uagen output.
+ - Slightly improve the wording of the ca-key-file documentation.
+ - Explicitly mention Windows 10 as supported so search engines and
+ users looking for it can find it.
+ - Import a bunch of contributors from the ChangeLog.
+ - Remove obsolete doc/gpl.html.
+ - Upgrade a couple of links to https://.
+ - Don't prefer the SourceForge patch tracker over the
+ privoxy-devel mailing list. While at it, link to the
+ SourceForge patch tracker.
+ - Mention http-inspection in the 'my browser warns me about
+ unauthenticated content' FAQ entry.
+ - Simplify the 'Is there is a license or fee?' FAQ entry.
+ - Add another +redirect{} example.
+ - Explicitly mention that interested sponsors should include
+ the link target in their first mail.
+ - Clarify that only Privoxy team members can object to new sponsors
+ and link to the list of current team members.
+ - Note that sponsor URLs may not contain keyword spam.
+ - Garbage collect doc/webserver/images which isn't referenced anymore.
+ - Update the method to reach the proxy settings in Firefox.
+ - Update proxy_setup.jpg description to refer to Firefox.
+ - Regenerate proxy_setup.jpg with a more recent Firefox (78.0).
+ - Regenerate files-in-use.jpg without obsolete standard.action
+ with modern colors and a slightly better quality.
+ - Update URL to the actionsfile tracker.
+ - Update a support request URL.
+ - Rephrase the 'Can Privoxy run as service' FAQ entry and
+ remove an obsolete paragraph.
+ - Let the 'Where can I get updated Actions Files?' entry link to
+ the gitweb version of default.action.master.
+ - Update a link to the default.action file.
+ - Update URLs for trackers and mailing lists.
+ - Replace CVS reference with git.
+ - Mention regression-tests.action in the config file.
+ - Explicitly mention in the config file that access to the
+ ca key should be limited to Privoxy.
+ - List more client-specific-tag examples for inspiration.
+ - Add additional headers to the client-header-order example.
+ - Note that actions aren't updated after rewrites.
+ - Explicitly mention that upgrading from http to https with
+ a client-header filter is not supported
+ - Note that protocol and host have to be added when rewriting
+ the destination host for https-inspected requests.
+ - Explicitly mention that the CA key is used to sign certificates.
+
+- Developer Manual:
+ - Flesh out the build instructions for Debian.
+ - Remove the packaging instructions for RPM-based systems.
+ They don't work and we don't release RPM packages anymore anyway.
+ - Remove the packaging instructions for Solaris.
+ They don't work and we don't release Solaris packages anymore anyway.
+ - Update the suggested subject for the announce mails.
+ - Update upload instructions.
+ ftp://upload.sourceforge.net is no longer functional.
+ - Remove a couple of package-dependent upload instructions
+ that don't actually work.
+ - Remove 'cd current' that no longer works.
+ - Add regression-tests.action to the list of files that should be installed.
+ - Stop claiming that there are text versions of the manuals.
+ We stopped building them in 2008 (9ed36a3c5e6f12).
+ - Note that the 'webserver' target creates the link needed for the user-manual.
+ - Suggest to use the master branch as reference when creating
+ the ChangeLog so the steps work when the current branch differs
+ from master which is likely as the developer manual
+ suggests to use a local branch for development.
+ - Add the -s flag to the suggested 'git tag' command. We prefer signed tags.
+ - Mention that merges into 'master' should be avoided.
+ - Add git commands that should result in a merge-free history.
+ - Mention Privoxy-Regression-Test.
+ - Add a section id to reduce link churn.
+ - Recommend the dok-tidy target when building docs for the webserver.
+ - Add another plug for the privoxy-devel mailing list.
+ - Let the intro link the copyright section in the user manual instead
+ of giving an incomplete summary of the license status.
+ - Clarify that the webserver target uploads to the SourceForge webserver.
+ - Mark the documentation for the Mac OS X installers as out of date and
+ change the SCM name back to CVS.
+ - Fix the location of the installer modules for Mac OS X.
+ They are not actually available through git (yet).
+ - Don't speak of Privoxy version 3 in the past tense.
+ - Update the list of programs required for the release process.
+ - Put openssl command in 'command' tags.
+ - Update description of the webserver target which uses ssh, not scp.
+ - Remove obsolete reference to config.new.
+
+- Tests:
+ - Add another hide-referrer{conditional-block} test.
+ - Add another hide-referrer{conditional-forge} test.
+ - Fix a hide-referrer{conditional-forge} test
+ that expected an acceptable header to be forged.
+ - Fix a hide-referrer{conditional-block} test
+ that expected an acceptable Referer to be removed.
+ - Explain why the "Set Header = Host: whatever.example.org" test is
+ expected to fail when using a CGI prefix that starts with "https://".
+ - Explain why a connection-sharing test is known to fail
+ when using "https://p.p/" as CGI prefix.
+ - Add a link to Privoxy-Regression-Test to regression-tests.action
+ in case it isn't packaged.
+ - Add regression tests for pcre host patterns.
+
+- Privoxy Infrastructure:
+ - Import a Privoxy logo for the website.
+ - Update Tor onion service to HiddenServiceVersion 3.
+ - Display the "model" photos in a single row and remove placeholder images.
+ - Regenerate homepage with updated sponsor list.
+ - Use the '/sponsor' redirect for the link to the sponsor page.
+ - Git commit messages are sent to the Privoxy-commits mailing list.
+
+*** Version 3.0.29 stable ***
+
+- Security/Reliability:
+ - Fixed memory leaks when a response is buffered and the buffer
+ limit is reached or Privoxy is running out of memory.
+ Commits bbd53f1010b and 4490d451f9b. OVE-20201118-0001.
+ Sponsored by: Robert Klemme
+ - Fixed a memory leak in the show-status CGI handler when
+ no action files are configured. Commit c62254a686.
+ OVE-20201118-0002.
+ Sponsored by: Robert Klemme
+ - Fixed a memory leak in the show-status CGI handler when
+ no filter files are configured. Commit 1b1370f7a8a.
+ OVE-20201118-0003.
+ Sponsored by: Robert Klemme
+ - Fixes a memory leak when client tags are active.
+ Commit 245e1cf32. OVE-20201118-0004.
+ Sponsored by: Robert Klemme
+ - Fixed a memory leak if multiple filters are executed
+ and the last one is skipped due to a pcre error.
+ Commit 5cfb7bc8fe. OVE-20201118-0005.
+ - Prevent an unlikely dereference of a NULL-pointer that
+ could result in a crash if accept-intercepted-requests
+ was enabled, Privoxy failed to get the request destination
+ from the Host header and a memory allocation failed.
+ Commit 7530132349. CID 267165. OVE-20201118-0006.
+ - Fixed memory leaks in the client-tags CGI handler when
+ client tags are configured and memory allocations fail.
+ Commit cf5640eb2a. CID 267168. OVE-20201118-0007.
+ - Fixed memory leaks in the show-status CGI handler when memory
+ allocations fail. Commit 064eac5fd0 and commit fdee85c0bf3.
+ CID 305233. OVE-20201118-0008.
+
+- General improvements:
+ - Added experimental https inspection support which allows to filter
+ https traffic. To enable it, install MbedTLS and configure with
+ --with-mbedtls, or install OpenSSL or LibreSSL and configure
+ with --with-openssl.
+ Afterwards configure the directives in section 7 of the
+ config file and enable the +https-inspection action.
+ Initial MbedTLS-based code contributed by Vaclav Svec,
+ initial OpenSSL support contributed by Maxim Antonov.
+ With help from Nedzad Hrnjica and Ho+ Ho+ Ho+.
+ Integration and improvements sponsored by Robert Klemme.
+ - pcrs: Request JIT compilation if it's supported and
+ the filter isn't dynamic. This can speed up filtering.
+ - Added support for Brotli decompression.
+ Sponsored by: Robert Klemme
+ - Added FEATURE_EXTENDED_STATISTICS to gather statistics for
+ block reasons and filter executions. To enable it, configure
+ with --enable-extended-statistics and visit
+ http://config.privoxy.org/show-status.
+ Sponsored by: Robert Klemme
+ - Use the IP_FREEBIND socket option, if defined. This allows
+ Privoxy to bind to not-yet assigned IP addresses which is
+ useful in failover environments.
+ Patch by Sam Varshavchik.
+ - Allow to use extended host patterns and vanilla host patterns
+ at the same time by prefixing extended host patterns with
+ "PCRE-HOST-PATTERN:". To enable this, configure with
+ --enable-pcre-host-patterns.
+ Sponsored by: Robert Klemme
+ - Added "Cross-origin resource sharing" (CORS) support.
+ This allows to access Privoxy's CGI interface via JavaScript from
+ another domain (white-listed with the new cors-allowed-origin directive).
+ Based on a patch by Nedzad Hrnjica.
+ Sponsored by: Robert Klemme.
+ - Add SOCKS5 username/password support.
+ Based on a patch by Sam, improved by Ivan Romanov.
+ Closes Patch#141 and solves TODO#105.
+ - Bump the maximum number of action and filter files
+ to 100 each.
+ Sponsored by: Robert Klemme
+ - Fixed handling of filters with "split-large-forms 1"
+ when using the CGI editor.
+ Reported by withoutname in #921.
+ - Better detect a mismatch of connection details when
+ figuring out whether or not a connection can be reused.
+ - Don't send a "Connection failure" message instead of the
+ "DNS failure" message.
+ Sponsored by: Robert Klemme
+ - Let LOG_LEVEL_REQUEST log all requests. Previously unencrypted
+ requests were only logged with LOG_LEVEL_REQUEST when they weren't
+ crunched (in which case they were logged with LOG_LEVEL_CRUNCH).
+ This was documented behaviour, but logging all requests seems more useful.
+ - Fixed locking around localtime() and gmtime().
+ - Removed OS/2 support. We haven't provided OS/2 packages in years,
+ it complicated the code and it depended on a fallback snprintf()
+ implementation which is GPLv2 only.
+ - Remove the fallback snprintf() implementation
+ Now that OS/2 support is gone we no longer need it.
+ - Fixed a bunch of format specifiers log messages.
+ - Added a missing apostrophe in the 'More Privoxy' menu.
+ - Explicitly prevent use of FEATURE_CONNECTION_SHARING
+ without FEATURE_CONNECTION_KEEP_ALIVE. It makes no sense
+ and does not compile anyway.
+ Sponsored by: Robert Klemme
+ - Fix build without FEATURE_CONNECTION_KEEP_ALIVE.
+ Sponsored by: Robert Klemme
+ - Downgrade the 'Graceful termination requested' message
+ to LOG_LEVEL_INFO as it isn't an error.
+ Sponsored by: Robert Klemme
+ - decompress_iob(): Downgrade the no-content message to LOG_LEVEL_RE_FILTER
+ While at it, fix a typo in a comment.
+ Sponsored by: Robert Klemme
+ - Fixed a couple of cppcheck warnings.
+ - Rename LOG_LEVEL_GPC to LOG_LEVEL_REQUEST.
+ Only the shadow knows what "GPC" is supposed to stand for.
+ - Remove SourceForge references in copyright headers.
+ - Upgrade a bunch of links to the homepage to https://.
+ - Add 'no-brotli-accepted' filter which prevents the
+ use of Brotli compression.
+ - Changed license for pcrs to GPLv2+ after getting the
+ permission from Andreas. This allows to redistribute
+ Privoxy under the GPLv3 which is required when linking
+ to future mbedTLS versions which are expected to be
+ licensed under the Apache 2.0 license only.
+ - Updated a bunch of tests that have to expect status code 403
+ now after r1.168/070e904afa5.
+ - Lowercase the host name in the request line.
+ - Only set SOURCE_DATE_EPOCH if it's not already set so
+ distributions can overwrite it through the environment.
+
+- Documentation changes:
+ - Explain that Privoxy has to be distributed under the
+ GPLv3 (or later) when linked with an MbedTLS version
+ that is licensed under the Apache 2.0 license.
+ - Import the GNU GPLv3 and include it the user manual.
+ - Clarify FEATURE_FORCE_LOAD's description. It allows to bypass
+ blocking not filtering and only does it if blocks aren't enforced.
+ Reported by: Robert Klemme
+ - FAQ: Remove Zwiebelfreunde e.V. from the list of fiduciary sponsors
+ As of 2021 they no longer handle donations for foreign organisations
+ due to lack of resources.
+ - FAQ: Remove an obsolete comment with a link to the long-gone PDF manual.
+ - FAQ: Add a link to the TODO list.
+ - FAQ: Change the sponsor amounts to USD slightly rounding the
+ converted amounts up to get simple numbers.
+ Receiving USD is apparently easier for SPI and SPI is
+ preferred by sponsors as they can send invoices.
+ - Advertise the client-tags CGI page in the user manual.
+ - Stop advertising the show-version CGI page which no longer exists.
+ - Add yet another reason why +prevent-compression may cause problems.
+ - Don't claim that contributors need ssh. It's only needed for committers.
+ - Replace obsolete CVS instructions with Git instructions.
+ - Remove an obsolete comment
+
+- Config file changes:
+ - Change the suggested default-server-timeout to 5 to match the
+ suggested keep-alive-timeout. Otherwise using the defaults would
+ result in Privoxy reducing the default-server-timeout and logging
+ an error message.
+ Sponsored by: Robert Klemme
+ - Update the 'debug 1' description.
+ - Add a missing 'client-specific-tag' directive.
+ - Comment out trusted-cgi-referer pointing to example.org.
+
+- Action file improvements:
+ - Block requests to /(.*/)?piwik\.php
+ - Block requests to .connectaserver.de/
+ - Block requests to pixel.inforsea.com/
+ - Block requests to t.vi-serve.com/
+ - Block requests to .ioam.de/
+ - Block requests to t.9gag.com/img.gif

+ - Disable fast-redirects for issue.freebsdfoundation.org/
+ - Disable fast-redirects for .twitter.com/.*origin=http
+ - Unblock belco24.de/
+ - Add fast-redirects exception for .wikipedia.org/
+ - Add fast-redirects exception for oss-fuzz.com/
+ - Disable fast-redirects for .consensu.org/delivery/pixel\.php
+ and block the requests as image instead
+ - Unblock .adbinstaller.com/
+ Reported by lvm in #942.
+ - Unblock .adbshell.com
+ Reported by lvm in #942.
+ - Unblock .tagesschau.de/
+ - Disable fast-redirects for collector.githubapp.com/
+ and block requests to it as image instead
+ - Unblock 'ada*.'
+ - Add fast-redirects{} exception for sourcepoint.vice.com/
+ - Unblock adaway.org/
+ Reported by DRS David Soft in AF#945.
+ - Change two block reasons that previously were the same.
+ Sponsored by: Robert Klemme
+ - Added a +delay-response{} test.
+ - Updated the location of the development version
+ of default.action.master.
+
+- Privoxy-Log-Parser:
+ - Added a --keep-date option to keep the date in highlighted messages.
+ - Highlight new log messages.
+ - Make gather_loglevel_clf_stats() more tolerant. While at it,
+ count all CLF messages as requests, even if the request is invalid.
+ - Only show HTTP version distribution if at least one version has been detected.
+ - Only show crunch statistics if crunches were detected.
+ - Warn if the request counts differ.
+ - Generate statistics if the log only contains LOG_LEVEL_CLF messages
+ so it can be used with vanilla webserver logs.
+ Previously Privoxy-specific "Request:" messages were required.
+ - Align the client-HTTP-version distribution like other distributions
+ - Bump version to 0.9.1
+ - Include status code distribution in the stats.
+ - Let the statistics include the size of the content Privoxy
+ transferred excluding HTTP headers.
+ - Get with the program and expect all requests to be logged with LOG_LEVEL_REQUEST.
+ It's no longer necessary to count both LOG_LEVEL_REQUEST and
+ LOG_LEVEL_CRUNCH messages to get the total number of requests.
+ - Leverage the LOG_LEVEL_CLF message to gather statistics that where
+ previously taken from LOG_LEVEL_HEADER lines. This results in less
+ confusing results if https inspection is enabled in which case there
+ are two LOG_LEVEL_HEADER lines with request lines.
+ Sponsored by: Robert Klemme
+ - Properly highlight the filter results message. Previously a brace got lost.
+ - Prefer the number of CLF lines to get the total number of requests
+ as it works with older Privoxy versions as well.
+
+- Privoxy-Regression-Test:
+ - Turn curl's globbing mode off so we can allow more characters in URLs.
+ - Allow '[' and ']' in URLs.
+ - Include the action file when complaining about missing Sticky Actions.
+ - Fix a sentence in the documentation.
+ - Bump version to 0.7.1
+
+- url-pattern-translator:
+ - Detect a couple of pattern prefixes case-insensitively.
+ Sponsored by: Robert Klemme
+ - Skip CLIENT-TAG patterns.
+ Sponsored by: Robert Klemme
+ - Skip patterns that have already been converted.
+ It should now be safe to "convert" a file multiple times.
+ Sponsored by: Robert Klemme
+ - Add the new 'PCRE-HOST-PATTERN:' prefix.
+ Sponsored by: Robert Klemme
+
+*** Version 3.0.28 stable ***
+
+- 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.
+
+*** 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.

+ - 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:
- - Fix a logic bug that could cause Privoxy to reuse a tainted
- server socket.
- It could happen for server sockets that got tainted by a
- server-header-tagger-induced block, in which case Privoxy
- doesn't necessarily read the whole server response.
- 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.
+ - 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

If all other threads were already using more recent files,

- 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

Additional insight from Petr Pisar.
- - Disable filters if SDCH compression is used unless filtering is forced.
- If SDCH was combined with a supported compression algorithm,
- we'd previously try to decompress it, when successful apply
- the enabled filters and ditch the Content-Encoding header
- even though the SDCH compression wasn't removed.
- Reported by zebul666 in #3225863.
- 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.
