The most prominent new feature is "keep-alive" support for -outgoing connections. +This is mainly a bug-fix release for the previously released Privoxy 3.0.16. -See http://www.privoxy.org/3.0.11/user-manual/whatsnew.html for details. +It contains fixes for two bugs that could cause connections to hang under +certain circumstances when keep-alive support was enabled, until they timed +out or where closed by the server. + +See http://www.privoxy.org/3.0.17/user-manual/whatsnew.html for details. -------------------------------------------------------------------- ChangeLog for Privoxy -------------------------------------------------------------------- - -*** Version 3.0.11 *** - -- On most platforms, outgoing connections can be kept alive and - reused if the server supports it. Whether or not this improves - things depends on the connection. -- When dropping privileges, membership in supplementary groups - is given up as well. Not doing that can lead to Privoxy running - with more rights than necessary and violates the principle of - least privilege. Users of the --user option are advised to update. - Thanks to Matthias Drochner for reporting the problem, - providing the initial patch and testing the final version. -- Passing invalid users or groups with the --user option - didn't lead to program exit. Regression introduced in 3.0.7. -- The match all section has been moved from default.action - to a new file called match-all.action. As a result the - default.action no longer needs to be touched by the user - and can be safely overwritten by updates. -- The standard.action file has been removed. Its content - is now part of the default.action file. -- In some situations the logged content length was slightly too low. -- Crunched requests are logged with their own log level. - If you used "debug 1" in the past, you'll probably want - to additionally enable "debug 1024", otherwise only passed - requests will be logged. If you only care about crunched - requests, simply replace "debug 1" with "debug 1024". -- The crunch reason has been moved to the beginning of the - crunch message. For HTTP URLs, the protocol is logged as well. -- Log messages are shortened by printing the thread id on its - own (as opposed to putting it inside the string "Privoxy()"). -- The config option socket-timeout has been added to control - the time Privoxy waits for data to arrive on a socket. -- Support for remote toggling is controlled by the configure - option --disable-toggle only. In previous versions it also - depended on the action editor and thus configuring with the - --disable-editor option would disable remote toggling support - as well. -- Requests with invalid HTTP versions are rejected. -- The template symbol @date@ can be used to include a date(1)-like - time string. Initial patch submitted by Endre Szabo. -- Responses from shoutcast servers are accepted again. - Problem reported and fix suggested by Stefan. -- The hide-forwarded-for-headers action has been replaced with - the change-x-forwarded-for{} action which can also be used to - add X-Forwarded-For headers. The latter functionality already - existed in Privoxy versions prior to 3.0.7 but has been removed - as it was often used unintentionally (by not using the - hide-forwarded-for-headers action). -- A "clear log" view option was added to the mingw32 version - to clear out all of the lines in the Privoxy log window. - Based on a patch submitted by T Ford. -- The mingw32 version uses "critical sections" now, which prevents - log message corruption under load. As a side effect, the - "no thread-safe PRNG" warning could be removed as well. -- The mingw32 version's task bar icon is crossed out and - the color changed to gray if Privoxy is toggled off. +*** Version 3.0.17 Stable *** + +- Fixed last-chunk-detection for responses where the content was small + enough to be read with the body, causing Privoxy to wait for the + end of the content until the server closed the connection. + Reported by "Karsten" in #3028326. +- Responses with status code 204 weren't properly detected as body-less + like RFC2616 mandates. Like the previous bug, this caused Privoxy + to wait for the end of the content until the server closed the connection. + Fixes #3022042 and #3025553, reported by a user with no visible name. + Most likely also fixes a bunch of other AJAX-related problem reports + that got closed in the past due to insufficient information and lack + of feedback. +- Fixed an ACL bug that made it impossible to build a blacklist. + Usually the ACL directives are used in a whitelist, which worked + as expected, but blacklisting is still useful for public proxies + where one only needs to deny known abusers access. +- Added LOG_LEVEL_RECEIVED to log the not-yet-parsed data read from the + network. This should make debugging various parsing issues a lot easier. +- The IPv6 code is enabled by default on Windows versions that support it. + Patch submitted by oCameLo in #2942729. +- In mingw32 versions, the user.filter file is reachable through the + GUI, just like default.filter is. Feature request 3040263. +- Added the configure option --enable-large-file-support to set a few + defines that are required by platforms like GNU/Linux to support files + larger then 2GB. Mainly interesting for users without proper logfile + management. +- Logging with "debug 16" no longer stops at the first nul byte which is + pretty useless. Non-printable characters are replaced with their hex value + so the result can't span multiple lines making parsing them harder then + necessary. +- Privoxy logs when reading an action, filter or trust file. +- Fixed incorrect regression test markup which caused a test in + 3.0.16 to fail while Privoxy itself was working correctly. + While Privoxy accepts hide-referer, too, the action name is actually + hide-referrer which is also the name used one the final results page, + where the test expected the alias. + +- CGI interface improvements: + - In finish_http_response(), continue to add the 'Connection: close' + header if the client connection will not be kept alive. + Anonymously pointed out in #2987454. + - Apostrophes in block messages no longer cause parse errors + when the blocked page is viewed with JavaScript enabled. + Reported by dg1727 in #3062296. + - Fix a bunch of anchors that used underscores instead of dashes. + - Allow to keep the client connection alive after crunching the previous request. + Already opened server connections can be kept alive, too. + - In cgi_show_url_info(), don't forget to prefix URLs that only contain + http:// or https:// in the path. Fixes #2975765 reported by Adam Piggott. + - Show the 404 CGI page if cgi_send_user_manual() is called while + local user manual delivery is disabled. + +- Action file improvements: + - Enable user.filter by default. Suggested by David White in #3001830. + - Block .sitestat.com/. Reported by johnd16 in #3002725. + - Block .atemda.com/. Reported by johnd16 in #3002723. + - Block js.adlink.net/. Reported by johnd16 in #3002720. + - Block .analytics.yahoo.com/. Reported by johnd16 in #3002713. + - Block sb.scorecardresearch.com, too. Reported by dg1727 in #2992652. + - Fix problems noticed on Yahoo mail and news pages. + - Remove the too broad yahoo section, only keeping the + fast-redirects exception as discussed on ijbswa-devel@. + - Don't block adesklets.sourceforge.net. Reported in #2974204. + - Block chartbeat ping tracking. Reported in #2975895. + - Tag CSS and image requests with cautious and medium settings, too. + - Don't handle view.atdmt.com as image. It's used for click-throughs + so users should be able to "go there anyway". + Reported by Adam Piggott in #2975927. + - Also let the refresh-tags filter remove invalid refresh tags where + the 'url=' part is missing. Anonymously reported in #2986382. + While at it, update the description to mention the fact that only + refresh tags with refresh times above 9 seconds are covered. + - javascript needs to be blocked with +handle-as-empty-document to + work around Firefox bug 492459. So move .js blockers from + +block{Might be a web-bug.} -handle-as-empty-document + to + +block{Might be a web-bug.} +handle-as-empty-document + - ijbswa-Feature Requests-3006719 - Block 160x578 Banners. + - Block another omniture tracking domain + - Added a range-requests tagger. + - Added two sections to get Flickr's Ajax interface working with + default pre-settings. If you change the configuration to block + cookies by default, you'll need additional exceptions. + Reported by Mathias Homann in #3101419 and by Patrick on ijbswa-users@ + +- Documentation improvements: + - Explicitly mention how to match all URLs. + - Consistently recommend socks5 in the Tor FAQ entry and mention + its advantage compared to socks4a. Reported by David in #2960129. + - Slightly improve the explanation of why filtering may appear + slower than it is. + - Grammar fixes for the ACL section. + +- Privoxy-Log-Parser improvements: + - Also gather statistics for blocked and redirected requests. + - Provide the percentage of keep-alive offers the client accepted. + - Add a --url-statistics-threshold option. + - Also gather statistics for ressources, methods, and HTTP versions + used by the client. + - Add a --host-statistics-threshold option to also gather + statistics about how many request where made per host. + - Fix a bug in handle_loglevel_header() where a 'scan: ' got lost. + - Add a --shorten-thread-ids option to replace the thread id with + a decimal number. + - Accept and ignore: Looks like we got the last chunk together + with the server headers.

Marking + the server socket tainted after throwing 4 bytes away. + - Accept: Merged multiple header lines to: 'X-FORWARDED-PROTO: http X-HOST: 127.0.0.1' + +- Code cleanups: + - Remove the next member from the client_state struct. Only the main + thread needs access to all client states so give it its own struct. + - Garbage-collect request_contains_null_bytes(). + - Ditch redundant code in unload_configfile(). + - Ditch LogGetURLUnderCursor() which doesn't seem to be used anywhere. + - In write_socket(), remove the write-only variable write_len in + an ifdef __OS2__ block. Spotted by cppcheck. + - In connect_to(), don't declare the variable 'flags' on OS/2 where + it isn't used. Spotted by cppcheck. + - Limit the scope of various variables. Spotted by cppcheck. + - In add_to_iob(), turn an interestingly looking for loop into a + boring while loop. + - Code cleanup in preparation for external filters. + - In listen_loop(), mention the socket on which we accepted the + connection, not just the source IP address. + - In write_socket(), also log the socket we're writing to. + - In log_error(), assert that escaped characters get logged + completely or not at all. + - In log_error(), assert that ival and sval have reasonable values. + There's no reason not to abort() if they don't. + - Remove an incorrect cgi_error_unknown() call in a + cannnot-happen-situation in send_crunch_response(). + - Clean up white-space in http_response definition and + move the crunch_reason to the beginning. + - Turn http_response.reason into an enum and rename it + to http_response.crunch_reason. + - Silence a 'gcc (Debian 4.3.2-1.1) 4.3.2' warning on i686 GNU/Linux. + +- GNUmakefile improvements: + - Use $(SSH) instead of ssh, so one only needs to specify a username once. + - Removed references to the action feedback thingy that hasn't been + working for years. + - Consistently use shell.sourceforge.net instead of shell.sf.net so + one doesn't need to check server fingerprints twice. + - Removed GNUisms in the webserver and webactions targets so they + work with standard tar. ----------------------------------------------------------------- About Privoxy: ----------------------------------------------------------------- -Privoxy is a non-caching web proxy with advanced filtering -capabilities for enhancing privacy, modifying web page data, -managing HTTP cookies, controlling access, and removing ads, -banners, pop-ups and other obnoxious Internet junk.
