OVE-20201118-0008. +- 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. + Previously 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. + - When https inspection is enabled and Privoxy has been compiled with + FEATURE_GRACEFUL_TERMINATION (not recommended for production builds), + the TLS backend resources are free'd later on and only if no active + connections are left. Prevents crashes when exiting "gracefully" at the + wrong time. - 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. + - Allow to rewrite the request destination for https-inspected + 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 - - Downgrade the 'Graceful termination requested' message - to LOG_LEVEL_INFO as it isn't an error. + - 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 - - 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. + - 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. + - The chdir() return code is checked to fix a compiler warning. + - The packages feed has been removed from the source tarball. + It's usually out of date when the source tarball is generated + for the release. + - Fixed 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. + - Remove unused variable in the OpenSSL-specific code. + - Update bug tracker URL in cgi_error_unknown(). + - 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. + - A couple of structures have been rearranged to require slightly + less memory. + - When https inspection is enabled and the certificate is invalid + the error message is now sent with status code 403 instead of 200. + - The Slackware rc script template has been renamed to + slackware/rc.privoxy.in to silence complaints when building + Debian packages. + - When building with MbedTLS support, mbedtls_md5_ret() is used + instead of mbedtls_md5() which is deprecated and causes a warning + on Debian GNU/Linux. - 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 - - Block requests to .pixel.parsely.com/ as image - - Block requests to pixel.wp.com/ - - Disable fast-redirects for .librarything.com/ - - 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. + - 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/. + - Block requests for trc-events.taboola.com/. + +- Filter file improvements: + - A allow-autocompletion filter has been added 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. + - Removed a duplicated pcrs command from the js-annoyances filter. + - The crude-parental filter now provides a short reason when blocking, + inserts a link to Privoxy's webinterface and adds a new line at + the end of the generated page. - 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. + - Highlight a few more messages. + - Add a handler for tagging messages. + - Properly deal with 'Certificate error' crunches + Previously the error description was highlighted as 'host'. + - Log truncated LOG_LEVEL_CLF messages more gracefully + and note that the statistics will be imprecise. + - Fixed perldoc typo. + - Bump version to 0.9.2. - 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 - + - 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://.

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.
