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 +ChangeLog for Privoxy 3.0.28 -------------------------------------------------------------------- -*** 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. +- 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: - - 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 *** + - 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: - - If a generated redirect URL contains characters RFC 3986 doesn't - permit, they are (re)encoded. Not doing this makes Privoxy versions - from 3.0.5 to 3.0.17 susceptible to HTTP response splitting (CWE-113) - attacks if the +fast-redirects{check-decoded-url} action is used. - - Fix a logic bug that could cause Privoxy to reuse a server - socket after it got tainted by a server-header-tagger-induced - block that was triggered before the whole server response had - been read. If keep-alive was enabled and the request following - the blocked one was to the same host and using the same forwarding - settings, Privoxy would send it on the tainted server socket. - While the server would simply treat it as a pipelined request, - Privoxy would later on fail to properly parse the server's - response as it would try to parse the unread data from the - first response as server headers for the second one. - Regression introduced in 3.0.17. - - When implying keep-alive in client_connection(), remember that - the client didn't. Fixes a regression introduced in 3.0.13 that - would cause Privoxy to wait for additional client requests after - receiving a HTTP/1.1 request with "Connection: close" set - and connection sharing enabled. - With clients which terminates the client connection after detecting - that the whole body has been received it doesn't really matter, - but with clients that don't the connection would be kept open until - it timed out. - - Fix a subtle race condition between prepare_csp_for_next_request() - and sweep(). A thread preparing itself for the next client request - could briefly appear to be inactive. - If all other threads were already using more recent files, - the thread could get its files swept away under its feet. - So far this has only been reproduced while stress testing in - valgrind while touching action files in a loop. It's unlikely - to have caused any actual problems in the real world. - - Disable filters if SDCH compression is used unless filtering is forced. - If SDCH was combined with a supported compression algorithm, Privoxy - previously could try to decompress it and ditch the Content-Encoding - header even though the SDCH compression wasn't dealt with. - Reported by zebul666 in #3225863. - - Make a copy of the --user value and only mess with that when splitting - user and group. On some operating systems modifying the value directly - is reflected in the output of ps and friends and can be misleading. - Reported by zepard in #3292710. - - If forwarded-connect-retries is set, only retry if Privoxy is actually - forwarding the request. Previously direct connections would be retried - as well. - - Fixed a small memory leak when retrying connections with IPv6 - support enabled. - - Remove an incorrect assertion in compile_dynamic_pcrs_job_list() - It could be triggered by a pcrs job with an invalid pcre - pattern (for example one that contains a lone quantifier). - - If the --user argument user[.group] contains a dot, always bail out - if no group has been specified. Previously the intended, but undocumented - (and apparently untested), behaviour was to try interpreting the whole - argument as user name, but the detection was flawed and checked for '0' - instead of '\0', thus merely preventing group names beginning with a zero. - - In html_code_map[], use a numeric character reference instead of ' - which wasn't standardized before XHTML 1.0. - - Fix an invalid free when compiled with FEATURE_GRACEFUL_TERMINATION - and shut down through http://config.privoxy.org/die - - In get_actions(), fix the "temporary" backwards compatibility hack - to accept block actions without reason. - It also covered other actions that should be rejected as invalid. - Reported by Billy Crook. - -- General improvements: - - Privoxy can (re)compress buffered content before delivering - it to the client. Disabled by default as most users wouldn't - benefit from it. - - The +fast-redirects{check-decoded-url} action checks URL - segments separately. If there are other parameters behind - the redirect URL, this makes it unnecessary to cut them off - by additionally using a +redirect{} pcrs command. - Initial patch submitted by Jamie Zawinski in #3429848. - - When loading action sections, verify that the referenced filters - exist. Currently missing filters only result in an error message, - but eventually the severity will be upgraded to fatal. - - Allow to bind to multiple separate addresses. - Patch set submitted by Petr Pisar in #3354485. - - Set socket_error to errno if connecting fails in rfc2553_connect_to(). - Previously rejected direct connections could be incorrectly reported - as DNS issues if Privoxy was compiled with IPv6 support. - - Adjust url_code_map[] so spaces are replaced with %20 instead of '+' - While '+' can be used by client's submitting form data, this is not - actually what Privoxy is using the lookups for. This is more of a - cosmetic issue and doesn't fix any known problems. - - When compiled without FEATURE_FAST_REDIRECTS, do not silently - ignore +fast-redirect{} directives - - Added a workaround for GNU libc's strptime() reporting negative - year values when the parsed year is only specified with two digits. - On affected systems cookies with such a date would not be turned - into session cookies by the +session-cookies-only action. - Reported by Vaeinoe in #3403560 - - Fixed bind failures with certain GNU libc versions if no non-loopback - IP address has been configured on the system. This is mainly an issue - if the system is using DHCP and Privoxy is started before the network - is completely configured. - Reported by Raphael Marichez in #3349356. - Additional insight from Petr Pisar. - - Privoxy log messages now use the ISO 8601 date format %Y-%m-%d. - It's only slightly longer than the old format, but contains - the full date including the year and allows sorting by date - (when grepping in multiple log files) without hassle. - - In get_last_url(), do not bother trying to decode URLs that do - not contain at least one '%' sign. It reduces the log noise and - a number of unnecessary memory allocations. - - In case of SOCKS5 failures, dump the socks response in the log message. - - Simplify the signal setup in main(). - - Streamline socks5_connect() slightly. - - In socks5_connect(), require a complete socks response from the server. - Previously Privoxy didn't care how much data the server response - contained as long as the first two bytes contained the expected - values. While at it, shrink the buffer size so Privoxy can't read - more than a whole socks response. - - In chat(), do not bother to generate a client request in case of - direct CONNECT requests. It will not be used anyway. - - Reduce server_last_modified()'s stack size. - - Shorten get_http_time() by using strftime(). - - Constify the known_http_methods pointers in unknown_method(). - - Constify the time_formats pointers in parse_header_time(). - - Constify the formerly_valid_actions pointers in action_used_to_be_valid(). - - Introduce a GNUMakefile MAN_PAGE variable that defaults to privoxy.1. - The Debian package uses section 8 for the man page and this - should simplify the patch. - - Deduplicate the INADDR_NONE definition for Solaris by moving it to jbsockets.h - - In block_url(), ditch the obsolete workaround for ancient Netscape versions - that supposedly couldn't properly deal with status code 403. - - Remove a useless NULL pointer check in load_trustfile(). - - Remove two useless NULL pointer checks in load_one_re_filterfile(). - - Change url_code_map[] from an array of pointers to an array of arrays - It removes an unnecessary layer of indirection and on 64bit system reduces - the size of the binary a bit. - - Fix various typos. Fixes taken from Debian's 29_typos.dpatch by Roland Rosenfeld. - - Add a dok-tidy GNUMakefile target to clean up the messy HTML - generated by the other dok targets. - - GNUisms in the GNUMakefile have been removed. - - Change the HTTP version in static responses to 1.1 - - Synced config.sub and config.guess with upstream - 2011-11-11/386c7218162c145f5f9e1ff7f558a3fbb66c37c5. - - Add a dedicated function to parse the values of toggles. Reduces duplicated - code in load_config() and provides better error handling. Invalid or missing - toggle values are now a fatal error instead of being silently ignored. - - Terminate HTML lines in static error messages with \n instead of \r\n. - - Simplify cgi_error_unknown() a bit. - - In LogPutString(), don't bother looking at pszText when not - actually logging anything. - - Change ssplit()'s fourth parameter from int to size_t. - Fixes a clang complaint. - - Add a warning that the statistics currently can't be trusted. - Mention Privoxy-Log-Parser's --statistics option as - an alternative for the time being. - - In rfc2553_connect_to(), start setting cgi->error_message on error. - - Change the expected status code returned for http://p.p/die depending - on whether or not FEATURE_GRACEFUL_TERMINATION is available. - - In cgi_die(), mark the client connection for closing. - If the client will fetch the style sheet through another connection - it gets the main thread out of the accept() state and should thus - trigger the actual shutdown. - - Add a proper CGI message for cgi_die(). - - Don't enforce a logical line length limit in read_config_line(). - - Slightly refactor server_last_modified() to remove useless gmtime*() calls. - - In get_content_type(), also recognize '.jpeg' as JPEG extension. - - Add '.png' to the list of recognized file extensions in get_content_type(). - - In block_url(), consistently use the block reason "Request blocked by Privoxy" - In two places the reason was "Request for blocked URL" which hides the - fact that the request got blocked by Privoxy and isn't necessarily - correct as the block may be due to tags. - - In listen_loop(), reload the configuration files after accepting - a new connection instead of before. - Previously the first connection that arrived after a configuration - change would still be handled with the old configuration. - - In chat()'s receive-data loop, skip a client socket check if - the socket will be written to right away anyway. This can - increase the transfer speed for unfiltered content on fast - network connections. - - The socket timeout is used for SOCKS negotiations as well which - previously couldn't timeout. - - Don't keep the client connection alive if any configuration file - changed since the time the connection came in. This is closer to - Privoxy's behaviour before keep-alive support for client connection - has been added and also less confusing in general. - - Treat all Content-Type header values containing the pattern - 'script' as a sign of text. Reported by pribog in #3134970. + - 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: - - Moved the site-specific block pattern section below the one for the - generic patterns so for requests that are matched in both, the block - reason for the domain is shown which is usually more useful than showing - the one for the generic pattern. - - Remove -prevent-compression from the fragile alias. It's no longer - used anywhere by default and isn't known to break stuff anyway. - - Add a (disabled) section to block various Facebook tracking URLs. - Reported by Dan Stahlke in #3421764. - - Add a (disabled) section to rewrite and redirect click-tracking - URLs used on news.google.com. - Reported by Dan Stahlke in #3421755. - - Unblock linuxcounter.net/. - Reported by Dan Stahlke in #3422612. - - Block 'www91.intel.com/' which is used by Omniture. - Reported by Adam Piggott in #3167370. - - Disable the handle-as-empty-doc-returns-ok option and mark it as deprecated. - Reminded by tceverling in #2790091. - - Add ".ivwbox.de/" to the "Cross-site user tracking" section. - Reported by Nettozahler in #3172525. - - Unblock and fast-redirect ".awin1.com/.*=http://". - Reported by Adam Piggott in #3170921. - - Block "b.collective-media.net/". - - Widen the Debian popcon exception to "qa.debian.org/popcon". - Seen in Debian's 05_default_action.dpatch by Roland Rosenfeld. - - Block ".gemius.pl/" which only seems to be used for user tracking. - Reported by johnd16 in #3002731. Additional input from Lee and movax. - - Disable banners-by-size filters for '.thinkgeek.com/'. - The filter only seems to catch pictures of the inventory. - - Block requests for 'go.idmnet.bbelements.com/please/showit/'. - Reported by kacperdominik in #3372959. - - Unblock adainitiative.org/. - - Add a fast-redirects exception for '.googleusercontent.com/.*=cache'. - - Add a fast-redirects exception for webcache.googleusercontent.com/. - - Unblock http://adassier.wordpress.com/ and http://adassier.files.wordpress.com/. - -- Filter file improvements: - - Let the yahoo filter hide '.ads'. - - Let the msn filter hide overlay ads for Facebook 'likes' in search - results and elements with the id 's_notf_div'. They only seem to be - used to advertise site 'enhancements'. - - Let the js-events filter additionally disarm setInterval(). - Suggested by dg1727 in #3423775. - -- Documentation improvements: - - Clarify the effect of compiling Privoxy with zlib support. - Suggested by dg1727 in #3423782. - - Point out that the SourceForge messaging system works like a black - hole and should thus not be used to contact individual developers. - - Mention some of the problems one can experience when not explicitly - configuring an IP addresses as listen address. - - Explicitly mention that hostnames can be used instead of IP addresses - for the listen-address, that only the first address returned will be - used and what happens if the address is invalid. - Requested by Calestyo in #3302213. - -- Log message improvements: - - If only the server connection is kept alive, do not pretend to - wait for a new client request. - - Remove a superfluous log message in forget_connection(). - - In chat(), properly report missing server responses as such - instead of calling them empty. - - In forwarded_connect(), fix a log message nobody should ever see. - - Fix a log message in socks5_connect(), a failed write operation - was logged as failed read operation. - - Let load_one_actions_file() properly complain about a missing - '{' at the beginning of the file. - Simply stating that a line is invalid isn't particularly helpful. - - Do not claim to listen on a socket until Privoxy actually does. - Patch submitted by Petr Pisar #3354485 - - Prevent a duplicated LOG_LEVEL_CLF message when sending out - the "no-server-data" response. - - Also log the client socket when dropping a connection. - - Include the destination host in the 'Request ... marked for - blocking. limit-connect{...} doesn't allow CONNECT ...' message - Patch submitted by Saperski in #3296250. - - Prevent a duplicated log message if none of the resolved IP - addresses were reachable. - - In connect_to(), do not pretend to retry if forwarded-connect-retries - is zero or unset. - - When a specified user or group can't be found, put the name in - single-quotes when logging it. - - In rfc2553_connect_to(), explain getnameinfo() errors better. - - Remove a useless log message in chat(). - - When retrying to connect, also log the maximum number of connection - attempts. - - Rephrase a log message in compile_dynamic_pcrs_job_list(). - Divide the error code and its meaning with a colon. Call the pcrs - job dynamic and not the filter. Filters may contain dynamic and - non-dynamic pcrs jobs at the same time. Only mention the name of - the filter or tagger, but don't claim it's a filter when it could - be a tagger. - - In a fatal error message in load_one_actions_file(), cover both - URL and TAG patterns. - - In pcrs_strerror(), properly report unknown positive error code - values as such. Previously they were handled like 0 (no error). - - In compile_dynamic_pcrs_job_list(), also log the actual error code as - pcrs_strerror() doesn't handle all errors reported by pcre. - - Don't bother trying to continue chatting if the client didn't ask for it. - Reduces log noise a bit. - - Make two fatal error message in load_one_actions_file() more descriptive. - - In cgi_send_user_manual(), log when rejecting a file name due to '/' or '..'. - - In load_file(), log a message if opening a file failed. - The CGI error message alone isn't too helpful. - - In connection_destination_matches(), improve two log messages - to help understand why the destinations don't match. - - Rephrase a log message in serve(). Client request arrival - should be differentiated from closed client connections now. - - In serve(), log if a client connection isn't reused due to a - configuration file change. - - Let mark_server_socket_tainted() always mark the server socket tainted, - just don't talk about it in cases where it has no effect. It doesn't change - Privoxy's behaviour, but makes understanding the log file easier. - -- configure: - - Added a --disable-ipv6-support switch for platforms where support - is detected but doesn't actually work. - - Do not check for the existence of strerror() and memmove() twice - - Remove a useless test for setpgrp(2). Privoxy doesn't need it and - it can cause problems when cross-compiling. - - Rename the --disable-acl-files switch to --disable-acl-support. - Since about 2001, ACL directives are specified in the standard - config file. - - Update the URL of the 'Removing outdated PCRE version after the - next stable release' posting. The old URL stopped working after - one of SF's recent site "optimizations". Reported by Han Liu. - -- Privoxy-Regression-Test: - - Added --shuffle-tests option to increase the chances of detection race conditions. - - Added a --local-test-file option that allows to use Privoxy-Regression-Test without Privoxy. - - Added tests for missing socks4 and socks4a forwarders. - - The --privoxy-address option now works with IPv6 addresses containing brackets, too. - - Perform limited sanity checks for parameters that are supposed to have numerical values. - - Added a --sleep-time option to specify a number of seconds to - sleep between tests, defaults to 0. - - Disable the range-requests tagger for tests that break if it's enabled. - - Log messages use the ISO 8601 date format %Y-%m-%d. - - Fix spelling in two error messages. - - In the --help output, include a list of supported tests and their default levels. - - Adjust the tests to properly deal with FEATURE_TOGGLE being disabled. + - 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. + 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. ----------------------------------------------------------------- About Privoxy: @@ -385,73 +302,67 @@ networks.
