- Announcing Privoxy v.3.0.11
+ Announcing Privoxy v.3.0.17 stable
-----------------------------------------------------------------
-3.0.11 is a stable release which includes many enhancements but no major
-new features. The most prominent new feature is support for "keep-alive"
-connection. There are many small improvements.
+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.

ChangeLog for Privoxy
--------------------------------------------------------------------
+*** 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 or the
+ request timed out. 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.
+
+- 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@.
-*** 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.
+- 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 resources, 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 highlight: 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.
