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 - or the request timed out. 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. +- Bug fixes: + - Improve the handling of chunk-encoded responses by buffering the data + even if filters are disabled and properly keeping track of where the + various chunks are supposed to start and end. Previously Privoxy would + merely check the last bytes received to see if they looked like the + last-chunk. This failed to work if the last-chunk wasn't received in one + read and could also result in actual data being misdetected + as last-chunk. + Should fix: SF support request #1739. + Reported by: withoutname. + - remove_chunked_transfer_coding(): Refuse to de-chunk invalid data + Previously the data could get corrupted even further. + Now we simply pass the unmodified data to the client. + - gif_deanimate(): Tolerate multiple image extensions in a row. + This allows to deanimate all the gifs on: + https://commons.wikimedia.org/wiki/Category:Animated_smilies + Fixes SF bug #795 reported by Celejar. + - OpenSSL generate_host_certificate(): Use X509_get_subject_name() + instead of X509_get_issuer_name() to get the issuer for generated + website certificates so there are no warnings in the browser when using + an intermediate CA certificate instead of a self-signed root certificate. + Problem reported and patch submitted by Chakib Benziane. + - can_filter_request_body(): Fix a log message that contained a spurious u. + - handle_established_connection(): Check for pending TLS data from the client + before checking if data is available on the connection. + The TLS library may have already consumed all the data from the client + response in which case poll() and select() will not detect that data is + available to be read. + Sponsored by: Robert Klemme. + - ssl_send_certificate_error(): Don't crash if there's no certificate + information available. This is only relevant when Privoxy is built with + wolfSSL 5.0.0 or later (code not yet published). Earlier wolfSSL versions + or the other TLS backends don't seem to trigger the crash. + - socks5_connect(): Add support for target hosts specified as IPv4 address + Previously the IP address was sent as domain. + +- General improvements: + - Add a client-body-tagger action which creates tags based on + the content of the request body. + Sponsored by: Robert Klemme. + - When client-body filters are enabled, buffer the whole request + before opening a connection to the server. + Makes it less likely that the server connection times out + and we don't open a connection if the buffering fails anyway. + Sponsored by: Robert Klemme. + - Add periods to a couple of log messages. + - accept_connection(): Add missing space to a log message. + - Initialize ca-related defaults with strdup_or_die() so errors + aren't silently ignored. + - make_path: Use malloc_or_die() in cases where allocation errors + were already fatal anyway. + - handle_established_connection(): Improve an error message slightly. + - receive_client_request(): Reject https URLs without CONNECT request. + - Include all requests in the statistics if mutexes are available. + Previously in case of reused connections only the last request got + counted. The statistics still aren't perfect but it's an improvement. + - Add read_socks_reply() and start using it in socks5_connect() + to apply the socket timeout more consistently. + - socks5_connect(): Deal with domain names in the socks reply + - Add a filter for bundeswehr.de that hides the cookie and + privacy info banner. - 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. - - Fixed a link to the 'intercepting' entry and add another one. - - Rename the 'Other' section to 'Mailing Lists' and reword it - to make it clear that nobody is forced to use the trackers - - Note that 'anonymously' posting on the trackers may not always - be possible. - - Suggest to enable debug 32768 when suspecting parsing problems. - -- Privoxy-Log-Parser improvements: - - Gather statistics for ressources, methods, and HTTP versions - used by the client. - - Also gather statistics for blocked and redirected requests. - - Provide the percentage of keep-alive offers the client accepted. - - Add a --url-statistics-threshold option. - - 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. We better stop reading. - - Accept and ignore: Continue hack in da house. - - Accept and higlight: Rejecting connection from 10.0.0.2. - Maximum number of connections reached. - - Accept and highlight: Loading actions file: /usr/local/etc/privoxy/default.action - - Accept and highlight: Loading filter file: /usr/local/etc/privoxy/default.filter - - Accept and highlight: Killed all-caps Host header line: HOST: bestproxydb.com - - Accept and highlight: Reducing expected bytes to 0. 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. - - Fix white-space in a log message in remove_chunked_transfer_coding(). - While at it, add a note that the message doesn't seem to - be entirely correct and should be improved later on. - -- 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. + - Disable filter{banners-by-size} for .freiheitsfoo.de/. + - Disable filter{banners-by-size} for freebsdfoundation.org/. + - Disable fast-redirects for consent.youtube.com/. + - Block requests to ups.xplosion.de/. + - Block requests for elsa.memoinsights.com/t. + - Fix a typo in a test. + - Disable fast-redirects for launchpad.net/. + - Unblock .eff.org/. + - Stop unblocking .org/.*(image|banner) which appears to be too generous + It let requests like: + https://stats.noblogs.org/piwik.php?action_name=anti%20gentrifizierungs%20fest&idsite=10175&rec=1&r=220192&h=17&m=7&s=44&url=https%3A%2F%2Fmuellemcalling.noblogs.org%2F&urlref=https%3A%2F%2Fmuellemcalling.noblogs.org%2Finfostande%2F&_id=&_idn=1&_refts=0&send_image=0&cookie=1&res=1366x768&pv_id=eqr7jX&pf_net=7&pf_srv=3&pf_tfr=2281&pf_dm1=156 + pass. + The example URL http://www.gnu.org/graphics/gnu-head-banner.png is + already unblocked due to .gnu.org being unblocked. + - Unblock adfd.org/. + - Disable filter{banners-by-link} for .eff.org/. + - Block requests to odb.outbrain.com/. + - Disable fast-redirects for .gandi.net/. + - Disable fast-redirects{} for .onion/.*/status/. + - Disable fast-redirects{} for twitter.com/.*/status/. + - Unblock pinkstinks.de/. + - Disable fast-redirects for .hagalil.com/. + +- Privoxy-Log-Parser: + - Bump version to 0.9.5. + - Highlight more log messages. + - Highlight the Crunch reason only once.
