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@.
+
+- 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.
+
*** Version 3.0.16 Stable ***
-- The config file option handle-as-empty-doc-returns-ok has
- been added to work around Firefox bug #492459, which causes
- Firefox to hang if JavaScripts are blocked in certain situations.
-- Privoxy-Log-Parser is roughly 40% faster in highlighting mode.
-- In daemon mode, fd 0, 1 and 2 are bound to /dev/null.
-- Accepts quoted expiration dates even though RFC 2109 10.1.2
- doesn't seem to allow them. Reported anonymously.
-- uagen, a Firefox User-Agent generator for Privoxy and Mozilla
- browsers has been imported and is available in the tarballs
- tools directory.
+- Added the config file option handle-as-empty-doc-returns-ok to
+ work around Firefox bug #492459, which causes Firefox to hang
+ if JavaScripts are blocked in certain situations. The option is
+ enabled in the default config file.
+- Added the config file option default-server-timeout to control the
+ assumed default server timeout. Since Privoxy no longer returns
+ an error message for connection resets on reused client connections,
+ assuming larger server timeout values appears to actually work
+ pretty well as long as connections aren't shared.
- Added optional support for FreeBSD's accf_http(9). Use the
configure option --enable-accept-filter to enable it.
- Added fancier Privoxy icons for win32. Contributed by Jeff H.
+- In daemon mode, fd 0, 1 and 2 are bound to /dev/null.
- Resolve localhost using whatever address family the operating
system feels like. Previous betas would try to use IPv4 as this

- the assumed default server timeout. Since Privoxy no longer

- connections, assuming larger server timeout values appears to
- actually work pretty well as long as connections aren't shared.
-- Several log messages about client connections also mention
- the socket number.
+- In the action lists on CGI pages, actions and their parameters are
+ no longer separated with a space. The action file parser doesn't
+ actually allow this and will throw an invalid syntax error if actions
+ and parameters in the action files are separated. Not adding the
+ spaces means copy and pasting CGI output into the action files works.
+- The default keep-alive timeout has been reduced to 5 seconds to work
+ around hangs in clients that treat the proxy like any other host and
+ stop allowing any new connections if the "maximum number of
+ connections per host" is reached.
+- Several webbug URLs that look like they are leading to images are now
+ blocked as image instead of empty documents. Doing the latter causes
+ WebKit-based clients to show a "missing image" icon which may mess up
+ the layout.
+- The no-such-domain template is used for DNS resolution
+ problems with FEATURE_IPV6_SUPPORT enabled. Previously the
+ connect-failed template was used. Reported by 'zebul666'.
+- Accepts quoted expiration dates even though RFC 2109 10.1.2
+ doesn't seem to allow them. Reported anonymously.
- Don't try to forget connections if connection sharing is disabled.
This wasn't a real problem but caused an unnecessary log message.
-- The scripts in the tools directory treat unknown parameters
- as fatal errors.
- The still undocumented --enable-extended-host-patterns configure
option has a better description.
-- Fixed an error message that would claim a write to the
- server failed when actually writing to the client failed.
+- Fixed an error message that would claim a write to the server
+ failed when actually writing to the client failed.
- Log the crunch reason before trying to write to the client.
The log is easier to read that way.

- no longer separated with a space. The action file parser doesn't
- actually allow this and will throw an invalid syntax error if
- actions and parameters in the action files are separated.

+- Several log messages about client connections also mention
+ the socket number.
- handle-as-empty-document no longer depends on the image blocking
code being enabled.
+- Privoxy-Log-Parser is roughly 40% faster in highlighting mode.
+- uagen, a Firefox User-Agent generator for Privoxy and Mozilla
+ browsers has been imported and is available in the tarball's
+ tools directory.
+- The scripts in the tools directory treat unknown parameters

*** Version 3.0.15 Beta ***
the still-open connection will be reused for the client's next
request to the same destination. Note that this only matters
if connection-sharing is enabled.
