Privoxy 3.0.26 changes
- +Privoxy 3.0.29 fixes a couple of memory leaks and introduces https inspection + which allows to filter encrypted requests and responses.
+Changes in Privoxy 3.0.29 stable:
Bug fixes:
- +Security/Reliability:
accept_connection(): Fix crashes with "listen-addr :8118"
- -After jbsockets.c v1.136 a valid text representation of the - host address is required for the $listen-address variable. If no - host address has been specified, use an empty string to prevent - NULL pointer dereferences.
- -The problem was reported by Marvin Renich in Debian bug - #834941, the offending commit was tracked down by Roland in SF - Bug #902.
+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:
-Log when privoxy is toggled on or off via cgi interface.
+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.
Highlight the "Info: Now toggled " on/off log message in the - windows log viewer.
+pcrs: Request JIT compilation if it's supported and the filter isn't dynamic. This can speed up + filtering.
Highlight the loading actions/filter file log message in the - windows log viewer.
+Added support for Brotli decompression. Sponsored by: Robert Klemme
Mention client-specific tags on the toggle page as a - potentionally more appropriate alternative.
+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
Documentation improvements:
- -Update download section on the homepage. The downloads are - available from the website now.
+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.
Add sponsor FAQ
+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
Remove obsolete reference to mailing lists hosted at - SourceForge
+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.
Update the "Before the Release" section of the developer - manual.
+Add SOCKS5 username/password support. Based on a patch by Sam, improved by Ivan Romanov. Closes + Patch#141 and solves TODO#105.
Infrastructure improvements:
- -Add perl script to generate an RSS feed for the packages
- -Submitted by "Unknown": - https://lists.privoxy.org/pipermail/privoxy-devel/2016-July/000068.html
+Bump the maximum number of action and filter files to 100 each. Sponsored by: Robert Klemme
Build system improvements:
- -strptime.h: fix a compiler warning about ambiguous else
+Fixed handling of filters with "split-large-forms 1" when using the CGI editor. Reported by withoutname + in #921.
configure.in: Check for Docbook goo on the BSDs as well
+Better detect a mismatch of connection details when figuring out whether or not a connection can be + reused.
GNUMakefile.in: Let the dok-user target remove temporary - files
+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
Privoxy 3.0.25 beta introduces - client-specific tags and includes a couple of minor improvements. It will - be followed by a stable release in the near future.
- -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.
+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 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.
+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.
General improvements:
- +Documentation changes:
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.
+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.
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.
+FAQ: Add a link to the TODO list.
Add client-header-tagger 'listen-address'.
+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.
Include the listen-address in the log message when logging new - requests. Patch contributed by pursievro.
+Advertise the client-tags CGI page in the user manual.
Turn invalid max-client-connections values into fatal - errors.
+Stop advertising the show-version CGI page which no longer exists.
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.
+Add yet another reason why +prevent-compression may cause problems.
On Mac OS X the thread id in log messages are more likely to - be unique now.
+Don't claim that contributors need ssh. It's only needed for committers.
When complaining about missing filters, the filter type is - logged as well.
+Replace obsolete CVS instructions with Git instructions.
A couple of harmless coverity warnings were silenced (CID - #161202, CID #161203, CID #161211).
+Remove an obsolete comment
Action file improvements:
- +Config file changes:
Filtering is disabled for Range requests to let download - resumption and Windows updates work with the default - configuration.
+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.
Unblock ".ardmediathek.de/". Reported by ThTomate in #932.
+Add a missing 'client-specific-tag' directive.
+Comment out trusted-cgi-referer pointing to example.org.
Documentation improvements:
- +Action file improvements:
Add FAQ entry for crashes caused by memory limits.
+Block requests to /(.*/)?piwik\.php

+Block requests to .connectaserver.de/
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.
+Block requests to pixel.inforsea.com/

+Block requests to t.vi-serve.com/
A bunch of links were converted to https://.
+Block requests to .ioam.de/
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.
+Block requests to t.9gag.com/img.gif
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.
+Block requests to .pixel.parsely.com/ as image
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.
+Block requests to pixel.wp.com/
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.
+Disable fast-redirects for .librarything.com/
Add a FAQ entry for tainted sockets.
+Disable fast-redirects for issue.freebsdfoundation.org/
More sections in the documentation have stable URLs now.

+Change two block reasons that previously were the same. Sponsored by: Robert Klemme
The mailing lists at SourceForge have been deprecated, you can - subscribe to the new ones at: https://lists.privoxy.org/
+Added a +delay-response{} test.
Migrating the remaining services from SourceForge is work in - progress (TODO list item #53).
+Updated the location of the development version of default.action.master.
Build system improvements:
- +Privoxy-Log-Parser:
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.
+Added a --keep-date option to keep the date in highlighted messages.
Let the tarball-dist target skip files in ".git".
+Highlight new log messages.
Let the tarball-dist target work in cwds other than - current.
+Make gather_loglevel_clf_stats() more tolerant. While at it, count all CLF messages as requests, even if + the request is invalid.
Make the 'clean' target faster when run from a git - repository.
+Only show HTTP version distribution if at least one version has been detected.
Include tools in the generic distribution.
+Only show crunch statistics if crunches were detected.
Let the gen-dist target work in cwds other than current.
+Warn if the request counts differ.
Sort find output that is used for distribution tarballs to get - reproducible results.
+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.
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.
+Align the client-HTTP-version distribution like other distributions
Add regression-tests.action to the files that are - distributed.
+Bump version to 0.9.1
The gen-dist target which was broken since 2002 (r1.92) has - been fixed.
+Include status code distribution in the stats.
Remove genclspec.sh which has been obsolete since 2009.
+Let the statistics include the size of the content Privoxy transferred excluding HTTP headers.
Remove obsolete reference to Redhat spec file.
+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.
Remove the obsolete announce target which has been commented - out years ago.
+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
Let rsync skip files if the checksums match.
+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:
-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.
+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.
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 a sentence in the documentation.
Fix indentation in perldoc examples.
+Bump version to 0.7.1
+url-pattern-translator:
+Detect a couple of pattern prefixes case-insensitively. Sponsored by: Robert Klemme
Don't overlook directives in the first line of the action - file.
+Skip CLIENT-TAG patterns. Sponsored by: Robert Klemme
Bump version to 0.7.
+Skip patterns that have already been converted. It should now be safe to "convert" a file multiple + times. Sponsored by: Robert Klemme
Fix detection of the Privoxy version now that https:// is used - for the website.
+Add the new 'PCRE-HOST-PATTERN:' prefix. Sponsored by: Robert Klemme
