+ Announcing Privoxy 3.0.28 stable
--------------------------------------------------------------------
-This is mainly a bug-fix release for the previously released
-Privoxy 3.0.17. One of the fixes addresses a security issue.
+Privoxy 3.0.27 stable scales better in multi-user environments
+and brings a couple of tuning directives.
+
+Privoxy 3.0.28 stable fixes two regressions introduced in 3.0.27.

+ChangeLog for Privoxy 3.0.28
--------------------------------------------------------------------
-*** Version 3.0.18 stable ***
-
-- Bug fixes:
- - If a generated redirect URL contains characters RFC 3986 doesn't
- permit, they are (re)encoded. Not doing this makes Privoxy versions
- from 3.0.5 to 3.0.17 susceptible to HTTP response splitting (CWE-113)
- attacks if the +fast-redirects{check-decoded-url} action is used.
- - Fix a logic bug that could cause Privoxy to reuse a server
- socket after it got tainted by a server-header-tagger-induced
- block that was triggered before the whole server response had
- been read. If keep-alive was enabled and the request following
- the blocked one was to the same host and using the same forwarding
- settings, Privoxy would send it on the tainted server socket.
- While the server would simply treat it as a pipelined request,
- Privoxy would later on fail to properly parse the server's
- response as it would try to parse the unread data from the
- first response as server headers for the second one.
- Regression introduced in 3.0.17.
- - When implying keep-alive in client_connection(), remember that
- the client didn't. Fixes a regression introduced in 3.0.13 that
- would cause Privoxy to wait for additional client requests after
- receiving a HTTP/1.1 request with "Connection: close" set
- and connection sharing enabled.
- With clients which terminates the client connection after detecting
- that the whole body has been received it doesn't really matter,
- but with clients that don't the connection would be kept open until
- it timed out.
- - Fix a subtle race condition between prepare_csp_for_next_request()
- and sweep(). A thread preparing itself for the next client request
- could briefly appear to be inactive.
- If all other threads were already using more recent files,
- the thread could get its files swept away under its feet.
- So far this has only been reproduced while stress testing in
- valgrind while touching action files in a loop. It's unlikely
- to have caused any actual problems in the real world.
- - Disable filters if SDCH compression is used unless filtering is forced.
- If SDCH was combined with a supported compression algorithm, Privoxy
- previously could try to decompress it and ditch the Content-Encoding
- header even though the SDCH compression wasn't dealt with.
- Reported by zebul666 in #3225863.
- - Make a copy of the --user value and only mess with that when splitting
- user and group. On some operating systems modifying the value directly
- is reflected in the output of ps and friends and can be misleading.
- Reported by zepard in #3292710.
- - If forwarded-connect-retries is set, only retry if Privoxy is actually
- forwarding the request. Previously direct connections would be retried
- as well.
- - Fixed a small memory leak when retrying connections with IPv6
- support enabled.
- - Remove an incorrect assertion in compile_dynamic_pcrs_job_list()
- It could be triggered by a pcrs job with an invalid pcre
- pattern (for example one that contains a lone quantifier).
- - If the --user argument user[.group] contains a dot, always bail out
- if no group has been specified. Previously the intended, but undocumented
- (and apparently untested), behaviour was to try interpreting the whole
- argument as user name, but the detection was flawed and checked for '0'
- instead of '\0', thus merely preventing group names beginning with a zero.
- - In html_code_map[], use a numeric character reference instead of '
- which wasn't standardized before XHTML 1.0.
- - Fix an invalid free when compiled with FEATURE_GRACEFUL_TERMINATION
- and shut down through http://config.privoxy.org/die
- - In get_actions(), fix the "temporary" backwards compatibility hack
- to accept block actions without reason.
- It also covered other actions that should be rejected as invalid.
- Reported by Billy Crook.
+- 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.
+--------------------------------------------------------------------
+ChangeLog for Privoxy 3.0.27
+--------------------------------------------------------------------
- General improvements:
- - Privoxy can (re)compress buffered content before delivering
- it to the client. Disabled by default as most users wouldn't
- benefit from it.
- - The +fast-redirects{check-decoded-url} action checks URL
- segments separately. If there are other parameters behind
- the redirect URL, this makes it unnecessary to cut them off
- by additionally using a +redirect{} pcrs command.
- Initial patch submitted by Jamie Zawinski in #3429848.
- - When loading action sections, verify that the referenced filters
- exist. Currently missing filters only result in an error message,
- but eventually the severity will be upgraded to fatal.
- - Allow to bind to multiple separate addresses.
- Patch set submitted by Petr Pisar in #3354485.
- - Set socket_error to errno if connecting fails in rfc2553_connect_to().
- Previously rejected direct connections could be incorrectly reported
- as DNS issues if Privoxy was compiled with IPv6 support.
- - Adjust url_code_map[] so spaces are replaced with %20 instead of '+'
- While '+' can be used by client's submitting form data, this is not
- actually what Privoxy is using the lookups for. This is more of a
- cosmetic issue and doesn't fix any known problems.
- - When compiled without FEATURE_FAST_REDIRECTS, do not silently
- ignore +fast-redirect{} directives
- - Added a workaround for GNU libc's strptime() reporting negative
- year values when the parsed year is only specified with two digits.
- On affected systems cookies with such a date would not be turned
- into session cookies by the +session-cookies-only action.
- Reported by Vaeinoe in #3403560
- - Fixed bind failures with certain GNU libc versions if no non-loopback
- IP address has been configured on the system. This is mainly an issue
- if the system is using DHCP and Privoxy is started before the network
- is completely configured.
- Reported by Raphael Marichez in #3349356.
- Additional insight from Petr Pisar.
- - Privoxy log messages now use the ISO 8601 date format %Y-%m-%d.
- It's only slightly longer than the old format, but contains
- the full date including the year and allows sorting by date
- (when grepping in multiple log files) without hassle.
- - In get_last_url(), do not bother trying to decode URLs that do
- not contain at least one '%' sign. It reduces the log noise and
- a number of unnecessary memory allocations.
- - In case of SOCKS5 failures, dump the socks response in the log message.
- - Simplify the signal setup in main().
- - Streamline socks5_connect() slightly.
- - In socks5_connect(), require a complete socks response from the server.
- Previously Privoxy didn't care how much data the server response
- contained as long as the first two bytes contained the expected
- values. While at it, shrink the buffer size so Privoxy can't read
- more than a whole socks response.
- - In chat(), do not bother to generate a client request in case of
- direct CONNECT requests. It will not be used anyway.
- - Reduce server_last_modified()'s stack size.
- - Shorten get_http_time() by using strftime().
- - Constify the known_http_methods pointers in unknown_method().
- - Constify the time_formats pointers in parse_header_time().
- - Constify the formerly_valid_actions pointers in action_used_to_be_valid().
- - Introduce a GNUMakefile MAN_PAGE variable that defaults to privoxy.1.
- The Debian package uses section 8 for the man page and this
- should simplify the patch.
- - Deduplicate the INADDR_NONE definition for Solaris by moving it to jbsockets.h
- - In block_url(), ditch the obsolete workaround for ancient Netscape versions
- that supposedly couldn't properly deal with status code 403.
- - Remove a useless NULL pointer check in load_trustfile().
- - Remove two useless NULL pointer checks in load_one_re_filterfile().
- - Change url_code_map[] from an array of pointers to an array of arrays
- It removes an unnecessary layer of indirection and on 64bit system reduces
- the size of the binary a bit.
- - Fix various typos. Fixes taken from Debian's 29_typos.dpatch by Roland Rosenfeld.
- - Add a dok-tidy GNUMakefile target to clean up the messy HTML
- generated by the other dok targets.
- - GNUisms in the GNUMakefile have been removed.
- - Change the HTTP version in static responses to 1.1
- - Synced config.sub and config.guess with upstream
- 2011-11-11/386c7218162c145f5f9e1ff7f558a3fbb66c37c5.
- - Add a dedicated function to parse the values of toggles. Reduces duplicated
- code in load_config() and provides better error handling. Invalid or missing
- toggle values are now a fatal error instead of being silently ignored.
- - Terminate HTML lines in static error messages with \n instead of \r\n.
- - Simplify cgi_error_unknown() a bit.
- - In LogPutString(), don't bother looking at pszText when not
- actually logging anything.
- - Change ssplit()'s fourth parameter from int to size_t.
- Fixes a clang complaint.
- - Add a warning that the statistics currently can't be trusted.
- Mention Privoxy-Log-Parser's --statistics option as
- an alternative for the time being.
- - In rfc2553_connect_to(), start setting cgi->error_message on error.
- - Change the expected status code returned for http://p.p/die depending
- on whether or not FEATURE_GRACEFUL_TERMINATION is available.
- - In cgi_die(), mark the client connection for closing.
- If the client will fetch the style sheet through another connection
- it gets the main thread out of the accept() state and should thus
- trigger the actual shutdown.
- - Add a proper CGI message for cgi_die().
- - Don't enforce a logical line length limit in read_config_line().
- - Slightly refactor server_last_modified() to remove useless gmtime*() calls.
- - In get_content_type(), also recognize '.jpeg' as JPEG extension.
- - Add '.png' to the list of recognized file extensions in get_content_type().
- - In block_url(), consistently use the block reason "Request blocked by Privoxy"
- In two places the reason was "Request for blocked URL" which hides the
- fact that the request got blocked by Privoxy and isn't necessarily
- correct as the block may be due to tags.
- - In listen_loop(), reload the configuration files after accepting
- a new connection instead of before.
- Previously the first connection that arrived after a configuration
- change would still be handled with the old configuration.
- - In chat()'s receive-data loop, skip a client socket check if
- the socket will be written to right away anyway. This can
- increase the transfer speed for unfiltered content on fast
- network connections.
- - The socket timeout is used for SOCKS negotiations as well which
- previously couldn't timeout.
- - Don't keep the client connection alive if any configuration file
- changed since the time the connection came in. This is closer to
- Privoxy's behaviour before keep-alive support for client connection
- has been added and also less confusing in general.
- - Treat all Content-Type header values containing the pattern
- 'script' as a sign of text. Reported by pribog in #3134970.
+ - 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.
-- Action file improvements:
- - Moved the site-specific block pattern section below the one for the
- generic patterns so for requests that are matched in both, the block
- reason for the domain is shown which is usually more useful than showing
- the one for the generic pattern.
- - Remove -prevent-compression from the fragile alias. It's no longer
- used anywhere by default and isn't known to break stuff anyway.
- - Add a (disabled) section to block various Facebook tracking URLs.
- Reported by Dan Stahlke in #3421764.
- - Add a (disabled) section to rewrite and redirect click-tracking
- URLs used on news.google.com.
- Reported by Dan Stahlke in #3421755.
- - Unblock linuxcounter.net/.
- Reported by Dan Stahlke in #3422612.
- - Block 'www91.intel.com/' which is used by Omniture.
- Reported by Adam Piggott in #3167370.
- - Disable the handle-as-empty-doc-returns-ok option and mark it as deprecated.
- Reminded by tceverling in #2790091.
- - Add ".ivwbox.de/" to the "Cross-site user tracking" section.
- Reported by Nettozahler in #3172525.
- - Unblock and fast-redirect ".awin1.com/.*=http://".
- Reported by Adam Piggott in #3170921.
- - Block "b.collective-media.net/".
- - Widen the Debian popcon exception to "qa.debian.org/popcon".
- Seen in Debian's 05_default_action.dpatch by Roland Rosenfeld.
- - Block ".gemius.pl/" which only seems to be used for user tracking.
- Reported by johnd16 in #3002731. Additional input from Lee and movax.
- - Disable banners-by-size filters for '.thinkgeek.com/'.
- The filter only seems to catch pictures of the inventory.
- - Block requests for 'go.idmnet.bbelements.com/please/showit/'.
- Reported by kacperdominik in #3372959.
- - Unblock adainitiative.org/.
- - Add a fast-redirects exception for '.googleusercontent.com/.*=cache'.
- - Add a fast-redirects exception for webcache.googleusercontent.com/.
- - Unblock http://adassier.wordpress.com/ and http://adassier.files.wordpress.com/.
-
-- Filter file improvements:
- - Let the yahoo filter hide '.ads'.
- - Let the msn filter hide overlay ads for Facebook 'likes' in search
- results and elements with the id 's_notf_div'. They only seem to be
- used to advertise site 'enhancements'.
- - Let the js-events filter additionally disarm setInterval().
- Suggested by dg1727 in #3423775.
+- 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.
-- Documentation improvements:
- - Clarify the effect of compiling Privoxy with zlib support.
- Suggested by dg1727 in #3423782.
- - Point out that the SourceForge messaging system works like a black
- hole and should thus not be used to contact individual developers.
- - Mention some of the problems one can experience when not explicitly
- configuring an IP addresses as listen address.
- - Explicitly mention that hostnames can be used instead of IP addresses
- for the listen-address, that only the first address returned will be
- used and what happens if the address is invalid.
- Requested by Calestyo in #3302213.
-
-- Log message improvements:
- - If only the server connection is kept alive, do not pretend to
- wait for a new client request.
- - Remove a superfluous log message in forget_connection().
- - In chat(), properly report missing server responses as such
- instead of calling them empty.
- - In forwarded_connect(), fix a log message nobody should ever see.
- - Fix a log message in socks5_connect(), a failed write operation
- was logged as failed read operation.
- - Let load_one_actions_file() properly complain about a missing
- '{' at the beginning of the file.
- Simply stating that a line is invalid isn't particularly helpful.
- - Do not claim to listen on a socket until Privoxy actually does.
- Patch submitted by Petr Pisar #3354485
- - Prevent a duplicated LOG_LEVEL_CLF message when sending out
- the "no-server-data" response.
- - Also log the client socket when dropping a connection.
- - Include the destination host in the 'Request ... marked for
- blocking. limit-connect{...} doesn't allow CONNECT ...' message
- Patch submitted by Saperski in #3296250.
- - Prevent a duplicated log message if none of the resolved IP
- addresses were reachable.
- - In connect_to(), do not pretend to retry if forwarded-connect-retries
- is zero or unset.
- - When a specified user or group can't be found, put the name in
- single-quotes when logging it.
- - In rfc2553_connect_to(), explain getnameinfo() errors better.
- - Remove a useless log message in chat().
- - When retrying to connect, also log the maximum number of connection
- attempts.
- - Rephrase a log message in compile_dynamic_pcrs_job_list().
- Divide the error code and its meaning with a colon. Call the pcrs
- job dynamic and not the filter. Filters may contain dynamic and
- non-dynamic pcrs jobs at the same time. Only mention the name of
- the filter or tagger, but don't claim it's a filter when it could
- be a tagger.
- - In a fatal error message in load_one_actions_file(), cover both
- URL and TAG patterns.
- - In pcrs_strerror(), properly report unknown positive error code
- values as such. Previously they were handled like 0 (no error).
- - In compile_dynamic_pcrs_job_list(), also log the actual error code as
- pcrs_strerror() doesn't handle all errors reported by pcre.
- - Don't bother trying to continue chatting if the client didn't ask for it.
- Reduces log noise a bit.
- - Make two fatal error message in load_one_actions_file() more descriptive.
- - In cgi_send_user_manual(), log when rejecting a file name due to '/' or '..'.
- - In load_file(), log a message if opening a file failed.
- The CGI error message alone isn't too helpful.
- - In connection_destination_matches(), improve two log messages
- to help understand why the destinations don't match.
- - Rephrase a log message in serve(). Client request arrival
- should be differentiated from closed client connections now.
- - In serve(), log if a client connection isn't reused due to a
- configuration file change.
- - Let mark_server_socket_tainted() always mark the server socket tainted,
- just don't talk about it in cases where it has no effect. It doesn't change
- Privoxy's behaviour, but makes understanding the log file easier.
-
-- configure:
- - Added a --disable-ipv6-support switch for platforms where support
- is detected but doesn't actually work.
- - Do not check for the existence of strerror() and memmove() twice
- - Remove a useless test for setpgrp(2). Privoxy doesn't need it and
- it can cause problems when cross-compiling.
- - Rename the --disable-acl-files switch to --disable-acl-support.
- Since about 2001, ACL directives are specified in the standard
- config file.
- - Update the URL of the 'Removing outdated PCRE version after the
- next stable release' posting. The old URL stopped working after
- one of SF's recent site "optimizations". Reported by Han Liu.
-
-- Privoxy-Regression-Test:
- - Added --shuffle-tests option to increase the chances of detection race conditions.
- - Added a --local-test-file option that allows to use Privoxy-Regression-Test without Privoxy.
- - Added tests for missing socks4 and socks4a forwarders.
- - The --privoxy-address option now works with IPv6 addresses containing brackets, too.
- - Perform limited sanity checks for parameters that are supposed to have numerical values.
- - Added a --sleep-time option to specify a number of seconds to
- sleep between tests, defaults to 0.
- - Disable the range-requests tagger for tests that break if it's enabled.
- - Log messages use the ISO 8601 date format %Y-%m-%d.
- - Fix spelling in two error messages.
- - In the --help output, include a list of supported tests and their default levels.
- - Adjust the tests to properly deal with FEATURE_TOGGLE being disabled.
+- 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:
- - Perform limited sanity checks for command line parameters that
- are supposed to have numerical values.
- - Implement a --unbreak-lines-only option to try to revert MUA breakage.
- - Accept and highlight: Added header: Content-Encoding: deflate
- - Accept and highlight: Compressed content from 29258 to 8630 bytes.
- - Accept and highlight: Client request arrived in time on socket 21.
- - Highlight: Didn't receive data in time: a.fsdn.com:443
- - Accept log messages with ISO 8601 time stamps, too.
-
-- uagen:
- - Bump generated Firefox version to 8.0.
- - Only randomize the release date if the new --randomize-release-date
- option is enabled. Firefox versions after 4 use a fixed date string
- without meaning.
+ - 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.

+ - 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.

+- 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.
