One of the fixes addresses a security issue. +This is a bug-fix release for Privoxy 3.0.20 beta. It also addresses +a security issue that affects all previous Privoxy versions (on some +platforms). -------------------------------------------------------------------- ChangeLog for Privoxy -------------------------------------------------------------------- -*** Version 3.0.18 stable *** +*** Version 3.0.21 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. + - On POSIX-like platforms, network sockets with file descriptor + values above FD_SETSIZE are properly rejected. Previously they + could cause memory corruption in configurations that allowed + the limit to be reached. + - Compiles on OS/2 again now that unistd.h is only included + on platforms that have it. - 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. + - The show-status page shows the FEATURE_STRPTIME_SANITY_CHECKS status. + - A couple of assert()s that could theoretically dereference + NULL pointers in debug builds have been relocated. + - Added an LSB info block to the generic start script. + Based on a patch from Natxo Asenjo. + - The max-client-connections default has been changed to 128 + which should be more than enough for most setups. - Action file improvements: - - 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/. + - Block rover.ebay./ar.*\&adtype= instead of "/.*\&adtype=" which + caused too man false positives. + Reported by u302320 in #360284, additional feedback from Adam Piggott. + - Unblock '.advrider.com/' and '/.*ADVrider'. + Anonymously reported in #3603636. + - Stop blocking '/js/slider\.js'. + Reported by Adam Piggott in #3606635 and _lvm in #2791160. - Filter file improvements: - - 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. + - Added an iframes filter. + +- Documentation improvements: + - The whole GPLv2 text is included in the user manual now, + so Privoxy can serve it itself and the user can read it + without having to wade through GPLv3 ads first. + - Properly numbered and underlined a couple of section titles + in the config that where previously overlooked due to a flaw + in the conversion script. Reported by Ralf Jungblut. + - Improved the support instruction to hopefully make it harder to + unintentionally provide insufficient information when requesting + support. Previously it wasn't obvious that the information we need + in bug reports is usually also required in support requests. + - Removed documentation about packages that haven't been provided + in years. + +- Privoxy-Regression-Test: + - Only log the test number when not running in verbose mode + The position of the test is rarely relevant and it previously + wasn't exactly obvious which one of the numbers was useful to + repeat the test with --test-number. + +- GNUmakefile improvements: + - Factor generate-config-file out of config-file to make testing + more convenient. + - The clean target now also takes care of patch leftovers. + +*** Version 3.0.20 beta *** + +- Bug fixes: + - Client sockets are now properly shutdown and drained before being + closed. This fixes page truncation issues with clients that aggressively + pipeline data on platforms that otherwise discard already written data. + The issue mainly affected Opera users and was initially reported + by Kevin in #3464439, szotsaki provided additional information to track + down the cause. + - Fix latency calculation for shared connections (disabled by default). + It was broken since their introduction in 2009. The calculated latency + for most connections would be 0 in which case the timeout detection + failed to account for the real latency. + - Reject URLs with invalid port. Previously they were parsed incorrectly and + characters between the port number and the first slash were silently + dropped as shown by curl test 187. + - The default-server-timeout and socket-timeout directives accept 0 as + valid value. + - Fix a race condition on Windows that could cause Privoxy to become + unresponsive after toggling it on or off through the taskbar icon. + Reported by Tim H. in #3525694. + - Fix the compilation on Windows when configured without IPv6 support. + - Fix an assertion that could cause debug builds to abort() in case of + socks5 connection failures with "debug 2" enabled. + - Fix an assertion that could cause debug builds to abort() if a filter + contained nul bytes in the replacement text. + +- General improvements: + - Significantly improved keep-alive support for both client and server + connections. + - New debug log level 65536 which logs all actions that were applied to + the request. + - New directive client-header-order to forward client headers in a + different order than the one in which they arrived. + - New directive tolerate-pipelining to allow client-side pipelining. + If enabled (3.0.20 beta enables it by default), Privoxy will keep + pipelined client requests around to deal with them once the current + request has been served. + - New --config-test option to let Privoxy exit after checking whether or not + the configuration seems valid. The limitations noted in TODO #22 and #23 + still apply. Based on a patch by Ramkumar Chinchani. + - New limit-cookie-lifetime{} action to let cookies expire before the end + of the session. Suggested by Rick Sykes in #1049575. + - Increase the hard-coded maximum number of actions and filter files from + 10 to 30 (each). It doesn't significantly affect Privoxy's memory usage + and recompiling wasn't an option for all Privoxy users that reached the + limit. + - Add support for chunk-encoded client request bodies. Previously + chunk-encoded request bodies weren't guaranteed to be forwarded correctly, + so this can also be considered a bug fix although chunk-encoded request + bodies aren't commonly used in the real world. + - Add support for Tor's optimistic-data SOCKS extension, which can reduce the + latency for requests on newly created connections. Currently only the + headers are sent optimistically and only if the client request has already + been read completely which rules out requests with large bodies. + - After preventing the client from pipelining, don't signal keep-alive + intentions. When looking at the response headers alone, it previously + wasn't obvious from the client's perspective that no additional responses + should be expected. + - Stop considering client sockets tainted after receiving a request with body. + It hasn't been necessary for a while now and unnecessarily causes test + failures when using curl's test suite. + - Allow HTTP/1.0 clients to signal interest in keep-alive through the + Proxy-Connection header. While such client are rare in the real world, it + doesn't hurt and couple of curl tests rely on it. + - Only remove duplicated Content-Type headers when filters are enabled. + If they are not it doesn't cause ill effects and the user might not want it. + Downgrade the removal message to LOG_LEVEL_HEADER to clarify that it's not + an error in Privoxy and is unlikely to cause any problems in general. + Anonymously reported in #3599335. + - Set the socket option SO_LINGER for the client socket. + - Move several variable declarations to the beginning of their code block. + It's required when compiling with gcc 2.95 which is still used on some + platforms. Initial patch submitted by Simon South in #3564815. + - Optionally try to sanity-check strptime() results before trusting them. + Broken strptime() implementations have caused problems in the past and + the most recent offender seems to be FreeBSD's libc (standards/173421). + - When filtering is enabled, let Range headers pass if the range starts at + the beginning. This should work around (or at least reduce) the video + playback issues with various Apple clients as reported by Duc in #3426305. + - Do not confuse a client hanging up with a connection time out. If a client + closes its side of the connection without sending a request line, do not + send the CLIENT_CONNECTION_TIMEOUT_RESPONSE, but report the condition + properly. + - Allow closing curly braces as part of action values as long as they are + escaped. + - On Windows, the logfile is now written before showing the GUI error + message which blocks until the user acknowledges it. + Reported by Adriaan in #3593603. + - Remove an unreasonable parameter limit in the CGI interface. The new + parameter limit depends on the memory available and is currently unlikely + to be reachable, due to other limits in both Privoxy and common clients. + Reported by Andrew on ijbswa-users@. + - Decrease the chances of parse failures after requests with unsupported + methods were sent to the CGI interface. + +- Action file improvements: + - Remove the comment that indicated that updated default.action versions + are released on their own. + - Block 'optimize.indieclick.com/' and 'optimized-by.rubiconproject.com/' + - Unblock 'adjamblog.wordpress.com/' and 'adjamblog.files.wordpress.com/'. + Reported by Ryan Farmer in #3496116. + - Unblock '/.*Bugtracker'.

Reported by Zeno Kugy in #3520260. - 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. + - Revised all OS X sections due to new packaging module (OSXPackageBuilder). + - Update the list of supported operating systems to clarify that all Windows + versions after 95 are expected to work and note that the platform-specific + code for AmigaOS and QNX currently isn't maintained. + - Update 'Signals' section, the only explicitly handled signals are SIGINT, + SIGTERM and SIGHUP. + - Add Haiku to the list of operating systems on which Privoxy is known to + run. + - Add DragonFly to the list of BSDs on which Privoxy is known to run. + - Removed references to redhat-specific documentation set since it no longer + exists. + - Removed references to building PDFs since we no longer do so. + - Multiple listen-address directives are supported since 3.0.18, correct the + documentation to say so. + - Remove bogus section about long and short being preferable to int. + - Corrected some Internet JunkBuster references to Privoxy. + - Removed references to www.junkbusters.com since it is no longer + maintained. Reported by Angelina Matson. + - Various grammar and spelling corrections + - Add a client-header-tagger{} example for disabling filtering for range + requests. + - Correct a URL in the "Privoxy with Tor" FAQ. + - Spell 'refresh-tags' correctly. Reported by Don in #3571927. + - Sort manpage options alphabetically. + - Remove an incorrect sentence in the toggle section. The toggle state + doesn't affect whether or not the Windows version uses the tray icon. + Reported by Zeno Kugy in #3596395. + - Add new contributors since 3.0.19. - Log message improvements: - - 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. + - When stopping to watch a client socket due to pipelining, additionally log + the socket number. + - Log the client socket and its condition before closing it. This makes it + more obvious that the socket actually gets closed and should help when + diagnosing problems like #3464439. + - In case of SOCKS5 failures, do not explicitly log the server's response. + It hasn't helped so far and the response can already be logged by enabling + "debug 32768" anyway. This reverts v1.81 and the follow-up bug fix v1.84. + - Relocate the connection-accepted message from listen_loop() to serve(). + This way it's printed by the thread that is actually serving the + connection which is nice when grepping for thread ids in log files. + +- Code cleanups: + - Remove compatibility layer for versions prior to 3.0 since it has been + obsolete for more than 10 years now. + - Remove the ijb_isupper() and ijb_tolower() macros from parsers.c since + they aren't used in this file. + - Removed the 'Functions declared include:' comment sections since they tend + to be incomplete, incorrect and out of date and the benefit seems + questionable. + - Various comment grammar and comprehensibility improvements. + - Remove a pointless fflush() call in chat(). Flushing all streams pretty + much all the time for no obvious reason is ridiculous. + - Relocate ijb_isupper()'s definition to project.h and get the ijb_tolower() + definition from there, too. + - Relocate ijb_isdigit()'s definition to project.h. + - Rename ijb_foo macros to privoxy_foo. + - Add malloc_or_die() which will allow to simplify code paths where malloc() + failures don't need to be handled gracefully. + - Add strdup_or_die() which will allow to simplify code paths where strdup() + failures don't need to be handled gracefully. + - Replace strdup() calls with strdup_or_die() calls where it's safe and + simplifies the code. + - Fix white-space around parentheses. + - Add missing white-space behind if's and the following parentheses. + - Unwrap a memcpy() call in resolve_hostname_to_ip(). + - Declare pcrs_get_delimiter()'s delimiters[] static const. + - Various optimisations to remove dead code and merge inefficient code + structures for improved clarity, performance or code compactness. + - Various data type corrections. + - Change visibility of several code segments when compiling without + FEATURE_CONNECTION_KEEP_ALIVE enabled for clarity. + - In pcrs_get_delimiter(), do not use delimiters outside the ASCII range. + Fixes a clang complaint. + - Fix an error message in get_last_url() nobody is supposed to see. + Reported by Matthew Fischer in #3507301. + - Fix a typo in the no-zlib-support complaint. Patch submitted by Matthew + Fischer in #3507304. + - Shorten ssplit()'s prototype by removing the last two arguments. We always + want to skip empty fields and ignore leading delimiters, so having + parameters for this only complicates the API. + - Use an enum for the type of the action value. + - Rename action_name's member takes_value to value_type as it isn't used as + boolean. + - Turn family mismatches in match_sockaddr() into fatal errors. + - Let enlist_unique_header() verify that the caller didn't pass a header + containing either \r or \n. + - Change the hashes used in load_config() to unsigned int. That's what + hash_string() actually returns and using a potentially larger type + is at best useless. + - Use privoxy_tolower() instead of vanilla tolower() with manual casting of + the argument. + - Catch ssplit() failures in parse_cgi_parameters(). - Privoxy-Regression-Test: - - 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. + - Add an 'Overwrite condition' directive to skip any matching tests before + it. As it has a global scope, using it is more convenient than clowning + around with the Ignore directive. + - Log to STDOUT instead of STDERR. + - Include the Privoxy version in the output. + - Various grammar and spelling corrections in documentation and code. + - Additional tests for range requests with filtering enabled. + - Tests with mostly invalid range request. + - Add a couple of hide-if-modified-since{} tests with different date formats. + - Cleaned up the format of the regression-tests.action file to match the + format of default.action. + - Remove the "Copyright" line from print_version(). When using --help, every + line of screen space matters and thus shouldn't be wasted on things the + user doesn't care about. - Privoxy-Log-Parser: - - 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. + - Improve the --statistics performance by skipping sanity checks for input + that shouldn't affect the results anyway. Add a --strict-checks option + that enables some of the checks again, just in case anybody cares. + - The distribution of client requests per connection is included in + the --statistic output. + - The --accept-unknown-messages option has been removed and the behavior + is now the default. + - Accept and (mostly) highlight new log messages introduced with + Privoxy 3.0.20. - uagen: - - Bump generated Firefox version to 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. + - Bump generated Firefox version to 17. + +- GNUmakefile improvements: + - The dok-tidy target no longer taints documents with a tidy-mark + - Change RA_MODE from 0664 to 0644. Suggested by Markus Dittrich in + #3505445. + - Remove tidy's clean flag as it changes the scope of attributes. + Link-specific colors end up being applied to all text. Reported by Adam + Piggott in #3569551. + - Leave it up to the user whether or not smart tags are inserted. + - Let w3m itself do the line wrapping for the config file. It works better + than fmt as it can honour pre tags causing less unintentional line breaks. + - Ditch a pointless '-r' passed to rm to delete files. + - The config-file target now requires less manual intervention and updates + the original config. + - Change WDUMP to generate ASCII. Add WDUMP_UTF8 to allow UTF-8 in the + AUTHORS file so the names are right. + - Stop pretending that lynx and links are supported for the documentation. + +- configure improvements: + - On Haiku, do not pass -lpthread to the compiler. Haiku's pthreads + implementation is contained in its system library, libroot, so no + additional library needs to be searched. + Patch submitted by Simon South in #3564815. + - Additional Haiku-specific improvements. Disable checks intended for + multi-user systems as Haiku is presently single-user. Group Haiku-specific + settings in their own section, following the pattern for Solaris, OS/2 and + AmigaOS. Add additional library-related settings to remove the need for + providing configure with custom LDFLAGS. + Submitted by Simon South in #3574538. ----------------------------------------------------------------- About Privoxy: @@ -370,10 +387,11 @@ Helping hands and donations are welcome: * http://www.privoxy.org/faq/general.html#DONATE -At present, Privoxy is known to run on Windows(95, 98, ME, 2000, -XP, Vista), GNU/Linux (Ubuntu, RedHat, SuSE, Debian, Fedora, Gentoo and -others), Mac OSX, OS/2, AmigaOS, FreeBSD, NetBSD, OpenBSD, Solaris, and -various other flavors of Unix. +At present, Privoxy is known to run on Windows 95 and later versions +(98, ME, 2000, XP, Vista, Windows 7 etc.), GNU/Linux (RedHat, SuSE, +Debian, Fedora, Gentoo, Slackware and others), Mac OS X (10.4 and +upwards on PPC and Intel processors), OS/2, Haiku, DragonFly, +FreeBSD, NetBSD, OpenBSD, Solaris, and various other flavors of Unix.
