+ Announcing Privoxy 3.0.26 stable
+--------------------------------------------------------------------
+Privoxy 3.0.26 stable is a bug-fix release for the previously
+released 3.0.25 beta which introduced client-specific tags and
+included a couple of minor improvements.
--------------------------------------------------------------------
ChangeLog for Privoxy
--------------------------------------------------------------------
-*** Version 3.0.16 stable ***
-
-- 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
- is what most users expect, but this didn't work reliably on
- GNU/Linux systems.
-- 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 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.
-- Log the crunch reason before trying to write to the client.
- The log is easier to read that way.
-- 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
- as fatal errors.
-
-*** Version 3.0.15 beta ***
-
-- In case of missing server data, no error message is send to the
- client if the request arrived on a reused connection. The client
- is then supposed to silently retry the request without bothering
- the user. This should significantly reduce the frequency of the
- "No server or forwarder data received" error message many users
- reported.
-- More reliable detection of prematurely closed client sockets
- with keep-alive enabled.
-- FEATURE_CONNECTION_KEEP_ALIVE is decoupled from
- FEATURE_CONNECTION_SHARING and now available on
- all platforms.
-- Improved handling of POST requests on reused connections.
- Should fix problems with stalled connections after submitting
- form data with some browser configurations.
-- Fixed various latency calculation issues.
-- Allows the client to pass NTLM authentication requests to a
- forwarding proxy. This was already assumed and hinted to work
- in 3.0.13 beta but actually didn't. Now it's confirmed to work
- with IE, Firefox and Chrome.
- Thanks to Francois Botha and Wan-Teh Chang
-- Fixed a calculation problem if receiving the server headers
- takes more than two reads, that could cause Privoxy to terminate
- the connection prematurely. Reported by Oliver.
-- Compiles again on platforms such as OpenBSD and systems
- using earlier glibc version that don't support AI_ADDRCONFIG.
- Anonymously submitted in #2872591.
-- A bunch of MS VC project files and Suse and Redhat RPM spec
- files have been removed as they were no longer maintained for
- quite some time.
-- Overly long action lines are properly rejected with a proper
- error message. Previously they would be either rejected as
- invalid or cause a core dump through abort().
-- Already timed-out connections are no longer temporarily remembered.
- They weren't reused anyway, but wasted a socket slot.
-- len refers to the number of bytes actually read which might
- differ from the ones received. Adjust log messages accordingly.
-- The optional JavaScript on the CGI page uses encodeURIComponent()
- instead of escape() which doesn't encode all characters that matter.
- Anonymously reported in #2832722.
-- Fix gcc45 warnings in decompress_iob().
-- Various log message improvements.
-- Privoxy-Regression-Test supports redirect tests.
-- Privoxy-Log-Parser can gather some connection statistics.
-
-*** Version 3.0.14 beta ***
-
-- The latency is taken into account when evaluating whether or not to
- reuse a connection. This should significantly reduce the number of
- connections problems several users reported.
-- If the server doesn't specify how long the connection stays alive,
- Privoxy errs on the safe side of caution and assumes it's only a second.
-- The error pages for connection timeouts or missing server data use a
- Last-Modified date in the past. Retry attempts are detected and Privoxy
- removes the If-Modified-Since header to prevent the server from responding
- with status code 304 in which case the client would reuse the error message.
-- Setting keep-alive-timeout to 0 disables keep-alive support. Previously
- Privoxy would claim to allow persistence but not reuse the connection.
-- Pipelined requests are less likely to be mistaken for the request
- body of the previous request. Note that Privoxy still has no real
- pipeline support and will either serialize pipelined requests or
- drop them in which case the client has to resent them.
-- Fixed a crash on some Windows versions when header randomization
- is enabled and the date couldn't be parsed.
-- Privoxy's keep-alive timeout for the current connection is reduced
- to the one specified in the client's Keep-Alive header.
-- For HTTP/1.1 requests, Privoxy implies keep-alive support by not
- setting any Connection header instead of using 'Connection: keep-alive'.
-- If the socket isn't reusable, Privoxy doesn't temporarily waste
- a socket slot to remember the connection.
-- If keep-alive support is disabled but compiled in, the client's
- Keep-Alive header is removed.
-- Fixed a bug on mingw32 where downloading large files failed if
- keep-alive support was enabled.
-- Fixed a bug that (at least theoretically) could cause log
- timestamps to be occasionally off by about a second.
-- No Proxy-Connection header if added if there already is one.
-- The configure script respects the $PATH variable when searching
- for groups and id.
-
-*** Version 3.0.13 beta ***
-
-- Added IPv6 support. Thanks to Petr Pisar who not only provided
- the initial patch but also helped a lot with the integration.
-- Added client-side keep-alive support.
-- The connection sharing code is only used if the connection-sharing
- option is enabled.
-- The max-client-connections option has been added to restrict
- the number of client connections below a value enforced by
- the operating system.
-- Fixed a regression reintroduced in 3.0.12 that could cause
- crashes on mingw32 if header date randomization was enabled.
-- Compressed content with extra fields couldn't be decompressed
- and would get passed to the client unfiltered. This problem
- has only be detected through statical analysis with clang as
- nobody seems to be using extra fields anyway.
-- If the server resets the Connection after sending only the headers
- Privoxy forwards what it got to the client. Previously Privoxy
- would deliver an error message instead.
-- Error messages in case of connection timeouts use the right
- HTTP status code.
-- If spawning a child to handle a request fails, the client
- gets an error message and Privoxy continues to listen for
- new requests right away.
-- The error messages in case of server-connection timeouts or
- prematurely closed server connections are now template-based.
-- If zlib support isn't compiled in, Privoxy no longer tries to
- filter compressed content unless explicitly asked to do so.
-- In case of connections that are denied based on ACL directives,
- the memory used for the client IP is no longer leaked.
-- Fixed another small memory leak if the client request times out
- while waiting for client headers other than the request line.
-- The client socket is kept open until the server socket has
- been marked as unused. This should increase the chances that
- 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.
-- A TODO list has been added to the source tarball to give potential
- volunteers a better idea of what the current goals are.
+- Bug fixes:
+ - Fixed crashes with "listen-addr :8118" (SF Bug #902).
+ The regression was introduced in 3.0.25 beta and reported
+ by Marvin Renich in Debian bug #834941.
+
+- General improvements:
+ - Log when privoxy is toggled on or off via cgi interface.
+ - Highlight the "Info: Now toggled " on/off log message
+ in the Windows log viewer.
+ - Highlight the loading actions/filter file log message
+ in the Windows log viewer.
+ - Mention client-specific tags on the toggle page as a
+ potentionally more appropriate alternative.
+
+- Documentation improvements:
+ - Update download section on the homepage.
+ The downloads are available from the website now.
+ - Add sponsor FAQ.
+ - Remove obsolete reference to mailing lists hosted at SourceForge.
+ - Update the "Before the Release" section of the developer manual.
+
+- Infrastructure improvements:
+ - Add perl script to generate an RSS feed for the packages
+ Submitted by "Unknown".
+
+- Build system improvements:
+ - strptime.h: fix a compiler warning about ambiguous else.
+ - configure.in: Check for Docbook goo on the BSDs as well.
+ - GNUMakefile.in: Let the dok-user target remove temporary files.
+
+*** Version 3.0.25 beta ***
+
+- Bug fixes:
+ - Always use the current toggle state for new requests.
+ Previously new requests on reused connections inherited
+ the toggle state from the previous request even though
+ the toggle state could have changed.
+ Reported by Robert Klemme.
+ - Fixed two buffer-overflows in the (deprecated) static
+ pcre code. These bugs are not considered security issues
+ as the input is trusted.
+ Found with afl-fuzz and ASAN.
+
+- General improvements:
+ - Added support for client-specific tags which allow Privoxy
+ admins to pre-define tags that are set for all requests from
+ clients that previously opted in through the CGI interface.
+ They are useful in multi-user setups where admins may
+ want to allow users to disable certain actions and filters
+ for themselves without affecting others.
+ In single-user setups they are useful to allow more fine-grained
+ toggling. For example to disable request blocking while still
+ crunching cookies, or to disable experimental filters only.
+ This is an experimental feature, the syntax and behaviour may
+ change in future versions.
+ Sponsored by Robert Klemme.
+ - Dynamic filters and taggers now support a $listen-address variable
+ which contains the address the request came in on.
+ For external filters the variable is called $PRIVOXY_LISTEN_ADDRESS.
+ Original patch contributed by pursievro.
+ - Add client-header-tagger 'listen-address'.
+ - Include the listen-address in the log message when logging new requests.
+ Patch contributed by pursievro.
+ - Turn invalid max-client-connections values into fatal errors.
+ - The show-status page now shows whether or not dates before 1970
+ and after 2038 are expected to be handled properly.
+ This is mainly useful for Privoxy-Regression-Test but could
+ also come handy when dealing with time-related support requests.
+ - On Mac OS X the thread id in log messages are more likely to
+ be unique now.
+ - When complaining about missing filters, the filter type is logged
+ as well.
+ - A couple of harmless coverity warnings were silenced
+ (CID #161202, CID #161203, CID #161211).
+
+- Action file improvements:
+ - Filtering is disabled for Range requests to let download resumption
+ and Windows updates work with the default configuration.
+ - Unblock ".ardmediathek.de/".
+ Reported by ThTomate in #932.
+
+- Documentation improvements:
+ - Add FAQ entry for crashes caused by memory limits.
+ - Remove obsolete FAQ entry about a bug in PHP 4.2.3.
+ - Mention the new mailing lists were appropriate.
+ As the archives have not been migrated, continue to
+ mention the archives at SF in the contacting section
+ for now.
+ - Note that the templates should be adjusted if Privoxy is
+ running as intercepting proxy without getting all requests.
+ - A bunch of links were converted to https://.
+ - Rephrase onion service paragraph to make it more obvious
+ that Tor is involved and that the whole website (and not
+ just the homepage) is available as onion service.
+ - Streamline the "More information" section on the homepage further
+ by additionally ditching the link to the 'See also' section
+ of the user manual. The section contains mostly links that are
+ directly reachable from the homepage already and the rest is
+ not significant enough to get a link from the homepage.
+ - Change the add-header{} example to set the DNT header
+ and use a complete section to make copy and pasting
+ more convenient.
+ Add a comment to make it obvious that adding the
+ header is not recommended for obvious reasons.
+ Using the DNT header as example was suggested by
+ Leo Wzukw.
+ - Streamline the support-and-service template
+ Instead of linking to the various support trackers
+ (whose URLs hopefully change soon), link to the
+ contact section of the user manual to increase the
+ chances that users actually read it.
+ - Add a FAQ entry for tainted sockets.
+ - More sections in the documentation have stable URLs now.
+ - FAQ: Explain why 'ping config.privoxy.org' is not expected
+ to reach a local Privoxy installation.
+ - Note that donations done through Zwiebelfreunde e.V. currently
+ can't be checked automatically.
+ - Updated section regarding starting Privoxy under OS X.
+ - Use dedicated start instructions for FreeBSD and ElectroBSD.
+ - Removed release instructions for AIX. They haven't been working
+ for years and unsurprisingly nobody seems to care.
+ - Removed obsolete reference to the solaris-dist target.
+ - Updated the release instructions for FreeBSD.
+ - Removed unfinished release instructions for Amiga OS and HP-UX 11.
+ - Added a pointer to the Cygwin Time Machine for getting the last release of
+ Cygwin version 1.5 to use for building Privoxy on Windows.
+ - Various typos have been fixed.
+
+- Infrastructure improvements:
+ - The website is no longer hosted at SourceForge and
+ can be reached through https now.
+ - The mailing lists at SourceForge have been deprecated,
+ you can subscribe to the new ones at: https://lists.privoxy.org/
+ - Migrating the remaining services from SourceForge is
+ work in progress (TODO list item #53).
+
+- Build system improvements:
+ - Add configure argument to optimistically redefine FD_SETSIZE
+ with the intent to change the maximum number of client
+ connections Privoxy can handle. Only works with some libcs.
+ Sponsored by Robert Klemme.
+ - Let the tarball-dist target skip files in ".git".
+ - Let the tarball-dist target work in cwds other than current.
+ - Make the 'clean' target faster when run from a git repository.
+ - Include tools in the generic distribution.
+ - Let the gen-dist target work in cwds other than current.
+ - Sort find output that is used for distribution tarballs
+ to get reproducible results.
+ - Don't add '-src' to the name of the tar ball generated by the
+ gen-dist target. The package isn't a source distribution but a
+ binary package.
+ While at it, use a variable for the name to reduce the chances
+ that the various references get out of sync and fix the gen-upload
+ target which was looking in the wrong directory.
+ - Add regression-tests.action to the files that are distributed.
+ - The gen-dist target which was broken since 2002 (r1.92) has been fixed.
+ - Remove genclspec.sh which has been obsolete since 2009.
+ - Remove obsolete reference to Redhat spec file.
+ - Remove the obsolete announce target which has been commented out years ago.
+ - Let rsync skip files if the checksums match.
+
+- Privoxy-Regression-Test:
+ - Add a "Default level offset" directive which can be used to
+ change the default level by a given value.
+ This directive affects all tests located after it until the end
+ of the file or a another "Default level offset" directive is reached.
+ The purpose of this directive is to make it more convenient to skip
+ similar tests in a given file without having to remove or disable
+ the tests completely.
+ - Let test level 17 depend on FEATURE_64_BIT_TIME_T
+ instead of FEATURE_PTHREAD which has no direct connection
+ to the time_t size.
+ - Fix indentation in perldoc examples.
+ - Don't overlook directives in the first line of the action file.
+ - Bump version to 0.7.
+ - Fix detection of the Privoxy version now that https://
+ is used for the website.
