-ChangeLog for Privoxy
---------------------------------------------------------------------
-*** Version 3.0.21 stable ***
-
-- Bug fixes:
- - On POSIX-like platforms, network sockets with file descriptor
- values above FD_SETSIZE are properly rejected. Previously they
- could cause memory corruption in configurations that allowed
- the limit to be reached.
- - Proxy authentication headers are removed unless the new directive
- enable-proxy-authentication-forwarding is used. Forwarding the
- headers potentionally allows malicious sites to trick the user
- into providing them with login information.
- Reported by Chris John Riley.
- - Compiles on OS/2 again now that unistd.h is only included
- on platforms that have it.
-
-- General improvements:
- - The show-status page shows the FEATURE_STRPTIME_SANITY_CHECKS status.
- - A couple of assert()s that could theoretically dereference
- NULL pointers in debug builds have been relocated.
- - Added an LSB info block to the generic start script.
- Based on a patch from Natxo Asenjo.
- - The max-client-connections default has been changed to 128
- which should be more than enough for most setups.
-
-- Action file improvements:
- - Block rover.ebay./ar.*\&adtype= instead of "/.*\&adtype=" which
- caused too man false positives.
- Reported by u302320 in #360284, additional feedback from Adam Piggott.
- - Unblock '.advrider.com/' and '/.*ADVrider'.
- Anonymously reported in #3603636.
- - Stop blocking '/js/slider\.js'.
- Reported by Adam Piggott in #3606635 and _lvm in #2791160.
-
-- Filter file improvements:
- - Added an iframes filter.
-
-- Documentation improvements:
- - The whole GPLv2 text is included in the user manual now,
- so Privoxy can serve it itself and the user can read it
- without having to wade through GPLv3 ads first.
- - Properly numbered and underlined a couple of section titles
- in the config that where previously overlooked due to a flaw
- in the conversion script. Reported by Ralf Jungblut.
- - Improved the support instruction to hopefully make it harder to
- unintentionally provide insufficient information when requesting
- support. Previously it wasn't obvious that the information we need
- in bug reports is usually also required in support requests.
- - Removed documentation about packages that haven't been provided
- in years.
-
-- Privoxy-Regression-Test:
- - Only log the test number when not running in verbose mode
- The position of the test is rarely relevant and it previously
- wasn't exactly obvious which one of the numbers was useful to
- repeat the test with --test-number.
-
-- GNUmakefile improvements:
- - Factor generate-config-file out of config-file to make testing
- more convenient.
- - The clean target now also takes care of patch leftovers.
-
-*** Version 3.0.20 beta ***
-
-- Bug fixes:
- - Client sockets are now properly shutdown and drained before being
- closed. This fixes page truncation issues with clients that aggressively
- pipeline data on platforms that otherwise discard already written data.
- The issue mainly affected Opera users and was initially reported
- by Kevin in #3464439, szotsaki provided additional information to track
- down the cause.
- - Fix latency calculation for shared connections (disabled by default).
- It was broken since their introduction in 2009. The calculated latency
- for most connections would be 0 in which case the timeout detection
- failed to account for the real latency.
- - Reject URLs with invalid port. Previously they were parsed incorrectly and
- characters between the port number and the first slash were silently
- dropped as shown by curl test 187.
- - The default-server-timeout and socket-timeout directives accept 0 as
- valid value.
- - Fix a race condition on Windows that could cause Privoxy to become
- unresponsive after toggling it on or off through the taskbar icon.
- Reported by Tim H. in #3525694.
- - Fix the compilation on Windows when configured without IPv6 support.
- - Fix an assertion that could cause debug builds to abort() in case of
- socks5 connection failures with "debug 2" enabled.
- - Fix an assertion that could cause debug builds to abort() if a filter
- contained nul bytes in the replacement text.
-
-- General improvements:
- - Significantly improved keep-alive support for both client and server
- connections.
- - New debug log level 65536 which logs all actions that were applied to
- the request.
- - New directive client-header-order to forward client headers in a
- different order than the one in which they arrived.
- - New directive tolerate-pipelining to allow client-side pipelining.
- If enabled (3.0.20 beta enables it by default), Privoxy will keep
- pipelined client requests around to deal with them once the current
- request has been served.
- - New --config-test option to let Privoxy exit after checking whether or not
- the configuration seems valid. The limitations noted in TODO #22 and #23
- still apply. Based on a patch by Ramkumar Chinchani.
- - New limit-cookie-lifetime{} action to let cookies expire before the end
- of the session. Suggested by Rick Sykes in #1049575.
- - Increase the hard-coded maximum number of actions and filter files from
- 10 to 30 (each). It doesn't significantly affect Privoxy's memory usage
- and recompiling wasn't an option for all Privoxy users that reached the
- limit.
- - Add support for chunk-encoded client request bodies. Previously
- chunk-encoded request bodies weren't guaranteed to be forwarded correctly,
- so this can also be considered a bug fix although chunk-encoded request
- bodies aren't commonly used in the real world.
- - Add support for Tor's optimistic-data SOCKS extension, which can reduce the
- latency for requests on newly created connections. Currently only the
- headers are sent optimistically and only if the client request has already
- been read completely which rules out requests with large bodies.
- - After preventing the client from pipelining, don't signal keep-alive
- intentions. When looking at the response headers alone, it previously
- wasn't obvious from the client's perspective that no additional responses
- should be expected.
- - Stop considering client sockets tainted after receiving a request with body.
- It hasn't been necessary for a while now and unnecessarily causes test
- failures when using curl's test suite.
- - Allow HTTP/1.0 clients to signal interest in keep-alive through the
- Proxy-Connection header. While such client are rare in the real world, it
- doesn't hurt and couple of curl tests rely on it.
- - Only remove duplicated Content-Type headers when filters are enabled.
- If they are not it doesn't cause ill effects and the user might not want it.
- Downgrade the removal message to LOG_LEVEL_HEADER to clarify that it's not
- an error in Privoxy and is unlikely to cause any problems in general.
- Anonymously reported in #3599335.
- - Set the socket option SO_LINGER for the client socket.
- - Move several variable declarations to the beginning of their code block.
- It's required when compiling with gcc 2.95 which is still used on some
- platforms. Initial patch submitted by Simon South in #3564815.
- - Optionally try to sanity-check strptime() results before trusting them.
- Broken strptime() implementations have caused problems in the past and
- the most recent offender seems to be FreeBSD's libc (standards/173421).
- - When filtering is enabled, let Range headers pass if the range starts at
- the beginning. This should work around (or at least reduce) the video
- playback issues with various Apple clients as reported by Duc in #3426305.
- - Do not confuse a client hanging up with a connection time out. If a client
- closes its side of the connection without sending a request line, do not
- send the CLIENT_CONNECTION_TIMEOUT_RESPONSE, but report the condition
- properly.
- - Allow closing curly braces as part of action values as long as they are
- escaped.
- - On Windows, the logfile is now written before showing the GUI error
- message which blocks until the user acknowledges it.
- Reported by Adriaan in #3593603.
- - Remove an unreasonable parameter limit in the CGI interface. The new
- parameter limit depends on the memory available and is currently unlikely
- to be reachable, due to other limits in both Privoxy and common clients.
- Reported by Andrew on ijbswa-users@.
- - Decrease the chances of parse failures after requests with unsupported
- methods were sent to the CGI interface.
-
-- Action file improvements:
- - Remove the comment that indicated that updated default.action versions
- are released on their own.
- - Block 'optimize.indieclick.com/' and 'optimized-by.rubiconproject.com/'
- - Unblock 'adjamblog.wordpress.com/' and 'adjamblog.files.wordpress.com/'.
- Reported by Ryan Farmer in #3496116.
- - Unblock '/.*Bugtracker'. Reported by pwhk in #3522341.
- - Add test URLs for '.freebsd.org' and '.watson.org'.
- - Unblock '.urbandictionary.com/popular'.
- - Block '.adnxs.com/'.
- - Block 'farm.plista.com/widgetdata.php'.
- - Block 'rotation.linuxnewmedia.com/'.
- - Block 'reklamy.sfd.pl/'. Reported by kacperdominik in #3399948.
- - Block 'g.adspeed.net/'.
- - Unblock 'websupport.wdc.com/'. Reported by Adam Piggot in #3577851.
- - Block '/openx/www/delivery/'.
- - Disable fast-redirects for '.googleapis.com/'.
- - Block 'imp.double.net/'. Reported by David Bo in #3070411.
- - Block 'gm-link.com/' which is used for email tracking.
- Reported by David Bo in #1812733.
- - Verify that requests to "bwp." are blocked. URL taken from #1736879
- submitted by Francois Marier.
- - Block '/.*bannerid='. Reported by Adam Piggott in #2975779.
- - Block 'cltomedia.info/delivery/' and '.adexprt.com/'.
- Anonymously reported in #2965254.
- - Block 'de17a.com/'. Reported by David Bo in #3061472.
- - Block 'oskar.tradera.com/'. Reported by David Bo in #3060596.
- - Block '/scripts/webtrends\.js'. Reported by johnd16 in #3002729.
- - Block requests for 'pool.*.adhese.com/'. Reported by johnd16 in #3002716.
- - Update path pattern for Coremetrics and add tests.
- Pattern and URLs submitted by Adam Piggott #3168443.
- - Enable +fast-redirects{check-decoded-url} for 'tr.anp.se/'.
- Reported by David Bo in #3268832.
- - Unblock '.conrad.se/newsletter/banners/'. Reported by David Bo in #3413824.
- - Block '.tynt.com/'. Reported by Dan Stahlke in #3421767.
- - Unblock '.bbci.co.uk/radio/'. Reported by Adam Piggott in #3569603.
- - Block requests to 'service.maxymiser.net/'.
- Reported by johnd16 in #3118401 (with a previous URL).
- - Disable fast-redirects for Google's "let's pretend your computer is
- infected" page.
- - Unblock '/.*download' to resolve actionsfile feedback #3498129.
- Submitted by Steven Kolins (soundcloud.com not working).
- - Unblock '.wlxrs.com/' which is required by hotmail.com.
- Fixes #3413827 submitted by David Bo.
- - Add two unblock patterns for popup radio and TV players.
- Submitted by Adam Piggott in #3596089.
-
-- Filter file improvements & bug fixes:
- - Add a referer tagger.
- - Reduce the likelihood that the google filter messes up HTML-generating
- JavaScript. Reported by Zeno Kugy in #3520260.
-
-- Documentation improvements:
- - Revised all OS X sections due to new packaging module (OSXPackageBuilder).
- - Update the list of supported operating systems to clarify that all Windows
- versions after 95 are expected to work and note that the platform-specific
- code for AmigaOS and QNX currently isn't maintained.
- - Update 'Signals' section, the only explicitly handled signals are SIGINT,
- SIGTERM and SIGHUP.
- - Add Haiku to the list of operating systems on which Privoxy is known to
- run.
- - Add DragonFly to the list of BSDs on which Privoxy is known to run.
- - Removed references to redhat-specific documentation set since it no longer
- exists.
- - Removed references to building PDFs since we no longer do so.
- - Multiple listen-address directives are supported since 3.0.18, correct the
- documentation to say so.
- - Remove bogus section about long and short being preferable to int.
- - Corrected some Internet JunkBuster references to Privoxy.
- - Removed references to www.junkbusters.com since it is no longer
- maintained. Reported by Angelina Matson.
- - Various grammar and spelling corrections
- - Add a client-header-tagger{} example for disabling filtering for range
- requests.
- - Correct a URL in the "Privoxy with Tor" FAQ.
- - Spell 'refresh-tags' correctly. Reported by Don in #3571927.
- - Sort manpage options alphabetically.
- - Remove an incorrect sentence in the toggle section. The toggle state
- doesn't affect whether or not the Windows version uses the tray icon.
- Reported by Zeno Kugy in #3596395.
- - Add new contributors since 3.0.19.
-
-- Log message improvements:
- - When stopping to watch a client socket due to pipelining, additionally log
- the socket number.
- - Log the client socket and its condition before closing it. This makes it
- more obvious that the socket actually gets closed and should help when
- diagnosing problems like #3464439.
- - In case of SOCKS5 failures, do not explicitly log the server's response.
- It hasn't helped so far and the response can already be logged by enabling
- "debug 32768" anyway. This reverts v1.81 and the follow-up bug fix v1.84.
- - Relocate the connection-accepted message from listen_loop() to serve().
- This way it's printed by the thread that is actually serving the
- connection which is nice when grepping for thread ids in log files.
-
-- Code cleanups:
- - Remove compatibility layer for versions prior to 3.0 since it has been
- obsolete for more than 10 years now.
- - Remove the ijb_isupper() and ijb_tolower() macros from parsers.c since
- they aren't used in this file.
- - Removed the 'Functions declared include:' comment sections since they tend
- to be incomplete, incorrect and out of date and the benefit seems
- questionable.
- - Various comment grammar and comprehensibility improvements.
- - Remove a pointless fflush() call in chat(). Flushing all streams pretty
- much all the time for no obvious reason is ridiculous.
- - Relocate ijb_isupper()'s definition to project.h and get the ijb_tolower()
- definition from there, too.
- - Relocate ijb_isdigit()'s definition to project.h.
- - Rename ijb_foo macros to privoxy_foo.
- - Add malloc_or_die() which will allow to simplify code paths where malloc()
- failures don't need to be handled gracefully.
- - Add strdup_or_die() which will allow to simplify code paths where strdup()
- failures don't need to be handled gracefully.
- - Replace strdup() calls with strdup_or_die() calls where it's safe and
- simplifies the code.
- - Fix white-space around parentheses.
- - Add missing white-space behind if's and the following parentheses.
- - Unwrap a memcpy() call in resolve_hostname_to_ip().
- - Declare pcrs_get_delimiter()'s delimiters[] static const.
- - Various optimisations to remove dead code and merge inefficient code
- structures for improved clarity, performance or code compactness.
- - Various data type corrections.
- - Change visibility of several code segments when compiling without
- FEATURE_CONNECTION_KEEP_ALIVE enabled for clarity.
- - In pcrs_get_delimiter(), do not use delimiters outside the ASCII range.
- Fixes a clang complaint.
- - Fix an error message in get_last_url() nobody is supposed to see.
- Reported by Matthew Fischer in #3507301.
- - Fix a typo in the no-zlib-support complaint. Patch submitted by Matthew
- Fischer in #3507304.
- - Shorten ssplit()'s prototype by removing the last two arguments. We always
- want to skip empty fields and ignore leading delimiters, so having
- parameters for this only complicates the API.
- - Use an enum for the type of the action value.
- - Rename action_name's member takes_value to value_type as it isn't used as
- boolean.
- - Turn family mismatches in match_sockaddr() into fatal errors.
- - Let enlist_unique_header() verify that the caller didn't pass a header
- containing either \r or \n.
- - Change the hashes used in load_config() to unsigned int. That's what
- hash_string() actually returns and using a potentially larger type
- is at best useless.
- - Use privoxy_tolower() instead of vanilla tolower() with manual casting of
- the argument.
- - Catch ssplit() failures in parse_cgi_parameters().
-
-- Privoxy-Regression-Test:
- - Add an 'Overwrite condition' directive to skip any matching tests before
- it. As it has a global scope, using it is more convenient than clowning
- around with the Ignore directive.
- - Log to STDOUT instead of STDERR.
- - Include the Privoxy version in the output.
- - Various grammar and spelling corrections in documentation and code.
- - Additional tests for range requests with filtering enabled.
- - Tests with mostly invalid range request.
- - Add a couple of hide-if-modified-since{} tests with different date formats.
- - Cleaned up the format of the regression-tests.action file to match the
- format of default.action.
- - Remove the "Copyright" line from print_version(). When using --help, every
- line of screen space matters and thus shouldn't be wasted on things the
- user doesn't care about.
-
-- Privoxy-Log-Parser:
- - Improve the --statistics performance by skipping sanity checks for input
- that shouldn't affect the results anyway. Add a --strict-checks option
- that enables some of the checks again, just in case anybody cares.
- - The distribution of client requests per connection is included in
- the --statistic output.
- - The --accept-unknown-messages option has been removed and the behavior
- is now the default.
- - Accept and (mostly) highlight new log messages introduced with
- Privoxy 3.0.20.
-
-- uagen:
- - Bump generated Firefox version to 17.
-
-- GNUmakefile improvements:
- - The dok-tidy target no longer taints documents with a tidy-mark
- - Change RA_MODE from 0664 to 0644. Suggested by Markus Dittrich in
- #3505445.
- - Remove tidy's clean flag as it changes the scope of attributes.
- Link-specific colors end up being applied to all text. Reported by Adam
- Piggott in #3569551.
- - Leave it up to the user whether or not smart tags are inserted.
- - Let w3m itself do the line wrapping for the config file. It works better
- than fmt as it can honour pre tags causing less unintentional line breaks.
- - Ditch a pointless '-r' passed to rm to delete files.
- - The config-file target now requires less manual intervention and updates
- the original config.
- - Change WDUMP to generate ASCII. Add WDUMP_UTF8 to allow UTF-8 in the
- AUTHORS file so the names are right.
- - Stop pretending that lynx and links are supported for the documentation.
-
-- configure improvements:
- - On Haiku, do not pass -lpthread to the compiler. Haiku's pthreads
- implementation is contained in its system library, libroot, so no
- additional library needs to be searched.
- Patch submitted by Simon South in #3564815.
- - Additional Haiku-specific improvements. Disable checks intended for
- multi-user systems as Haiku is presently single-user. Group Haiku-specific
- settings in their own section, following the pattern for Solaris, OS/2 and
- AmigaOS. Add additional library-related settings to remove the need for
- providing configure with custom LDFLAGS.
- Submitted by Simon South in #3574538.
-
-*** Version 3.0.19 Stable ***
-
-- Bug fixes:
- - Prevent a segmentation fault when de-chunking buffered content.
- It could be triggered by malicious web servers if Privoxy was
- configured to filter the content and running on a platform
- where SIZE_T_MAX isn't larger than UINT_MAX, which probably
- includes most 32-bit systems. On those platforms, all Privoxy
- versions before 3.0.19 appear to be affected.
- To be on the safe side, this bug should be presumed to allow
- code execution as proving that it doesn't seems unrealistic.
- - Do not expect a response from the SOCKS4/4A server until it
- got something to respond to. This regression was introduced
- in 3.0.18 and prevented the SOCKS4/4A negotiation from working.
- Reported by qqqqqw in #3459781.
-
-- General improvements:
- - Fix an off-by-one in an error message about connect failures.
- - Use a GNUMakefile variable for the webserver root directory and
- update the path. Sourceforge changed it which broke various
- web-related targets.
- - Update the CODE_STATUS description.
-
-*** Version 3.0.18 Stable ***
-
-- Bug fixes:
- - If a generated redirect URL contains characters RFC 3986 doesn't
- permit, they are (re)encoded. Not doing this makes Privoxy versions
- from 3.0.5 to 3.0.17 susceptible to HTTP response splitting (CWE-113)
- attacks if the +fast-redirects{check-decoded-url} action is used.
- - Fix a logic bug that could cause Privoxy to reuse a server
- socket after it got tainted by a server-header-tagger-induced
- block that was triggered before the whole server response had
- been read. If keep-alive was enabled and the request following
- the blocked one was to the same host and using the same forwarding
- settings, Privoxy would send it on the tainted server socket.
- While the server would simply treat it as a pipelined request,
- Privoxy would later on fail to properly parse the server's
- response as it would try to parse the unread data from the
- first response as server headers for the second one.
- Regression introduced in 3.0.17.
- - When implying keep-alive in client_connection(), remember that
- the client didn't. Fixes a regression introduced in 3.0.13 that
- would cause Privoxy to wait for additional client requests after
- receiving a HTTP/1.1 request with "Connection: close" set
- and connection sharing enabled.
- With clients which terminates the client connection after detecting
- that the whole body has been received it doesn't really matter,
- but with clients that don't the connection would be kept open until
- it timed out.
- - Fix a subtle race condition between prepare_csp_for_next_request()
- and sweep(). A thread preparing itself for the next client request
- could briefly appear to be inactive.
- If all other threads were already using more recent files,
- the thread could get its files swept away under its feet.
- So far this has only been reproduced while stress testing in
- valgrind while touching action files in a loop. It's unlikely
- to have caused any actual problems in the real world.
- - Disable filters if SDCH compression is used unless filtering is forced.
- If SDCH was combined with a supported compression algorithm, Privoxy
- previously could try to decompress it and ditch the Content-Encoding
- header even though the SDCH compression wasn't dealt with.
- Reported by zebul666 in #3225863.
- - Make a copy of the --user value and only mess with that when splitting
- user and group. On some operating systems modifying the value directly
- is reflected in the output of ps and friends and can be misleading.
- Reported by zepard in #3292710.
- - If forwarded-connect-retries is set, only retry if Privoxy is actually
- forwarding the request. Previously direct connections would be retried
- as well.
- - Fixed a small memory leak when retrying connections with IPv6
- support enabled.
- - Remove an incorrect assertion in compile_dynamic_pcrs_job_list()
- It could be triggered by a pcrs job with an invalid pcre
- pattern (for example one that contains a lone quantifier).
- - If the --user argument user[.group] contains a dot, always bail out
- if no group has been specified. Previously the intended, but undocumented
- (and apparently untested), behaviour was to try interpreting the whole
- argument as user name, but the detection was flawed and checked for '0'
- instead of '\0', thus merely preventing group names beginning with a zero.
- - In html_code_map[], use a numeric character reference instead of '
- which wasn't standardized before XHTML 1.0.
- - Fix an invalid free when compiled with FEATURE_GRACEFUL_TERMINATION
- and shut down through http://config.privoxy.org/die
- - In get_actions(), fix the "temporary" backwards compatibility hack
- to accept block actions without reason.
- It also covered other actions that should be rejected as invalid.
- Reported by Billy Crook.
-
-- General improvements:
- - Privoxy can (re)compress buffered content before delivering
- it to the client. Disabled by default as most users wouldn't
- benefit from it.
- - The +fast-redirects{check-decoded-url} action checks URL
- segments separately. If there are other parameters behind
- the redirect URL, this makes it unnecessary to cut them off
- by additionally using a +redirect{} pcrs command.
- Initial patch submitted by Jamie Zawinski in #3429848.
- - When loading action sections, verify that the referenced filters
- exist. Currently missing filters only result in an error message,
- but eventually the severity will be upgraded to fatal.
- - Allow to bind to multiple separate addresses.
- Patch set submitted by Petr Pisar in #3354485.
- - Set socket_error to errno if connecting fails in rfc2553_connect_to().
- Previously rejected direct connections could be incorrectly reported
- as DNS issues if Privoxy was compiled with IPv6 support.
- - Adjust url_code_map[] so spaces are replaced with %20 instead of '+'
- While '+' can be used by client's submitting form data, this is not
- actually what Privoxy is using the lookups for. This is more of a
- cosmetic issue and doesn't fix any known problems.
- - When compiled without FEATURE_FAST_REDIRECTS, do not silently
- ignore +fast-redirect{} directives
- - Added a workaround for GNU libc's strptime() reporting negative
- year values when the parsed year is only specified with two digits.
- On affected systems cookies with such a date would not be turned
- into session cookies by the +session-cookies-only action.
- Reported by Vaeinoe in #3403560
- - Fixed bind failures with certain GNU libc versions if no non-loopback
- IP address has been configured on the system. This is mainly an issue
- if the system is using DHCP and Privoxy is started before the network
- is completely configured.
- Reported by Raphael Marichez in #3349356.
- Additional insight from Petr Pisar.
- - Privoxy log messages now use the ISO 8601 date format %Y-%m-%d.
- It's only slightly longer than the old format, but contains
- the full date including the year and allows sorting by date
- (when grepping in multiple log files) without hassle.
- - In get_last_url(), do not bother trying to decode URLs that do
- not contain at least one '%' sign. It reduces the log noise and
- a number of unnecessary memory allocations.
- - In case of SOCKS5 failures, dump the socks response in the log message.
- - Simplify the signal setup in main().
- - Streamline socks5_connect() slightly.
- - In socks5_connect(), require a complete socks response from the server.
- Previously Privoxy didn't care how much data the server response
- contained as long as the first two bytes contained the expected
- values. While at it, shrink the buffer size so Privoxy can't read
- more than a whole socks response.
- - In chat(), do not bother to generate a client request in case of
- direct CONNECT requests. It will not be used anyway.
- - Reduce server_last_modified()'s stack size.
- - Shorten get_http_time() by using strftime().
- - Constify the known_http_methods pointers in unknown_method().
- - Constify the time_formats pointers in parse_header_time().
- - Constify the formerly_valid_actions pointers in action_used_to_be_valid().
- - Introduce a GNUMakefile MAN_PAGE variable that defaults to privoxy.1.
- The Debian package uses section 8 for the man page and this
- should simplify the patch.
- - Deduplicate the INADDR_NONE definition for Solaris by moving it to jbsockets.h
- - In block_url(), ditch the obsolete workaround for ancient Netscape versions
- that supposedly couldn't properly deal with status code 403.
- - Remove a useless NULL pointer check in load_trustfile().
- - Remove two useless NULL pointer checks in load_one_re_filterfile().
- - Change url_code_map[] from an array of pointers to an array of arrays
- It removes an unnecessary layer of indirection and on 64bit system reduces
- the size of the binary a bit.
- - Fix various typos. Fixes taken from Debian's 29_typos.dpatch by Roland Rosenfeld.
- - Add a dok-tidy GNUMakefile target to clean up the messy HTML
- generated by the other dok targets.
- - GNUisms in the GNUMakefile have been removed.
- - Change the HTTP version in static responses to 1.1
- - Synced config.sub and config.guess with upstream
- 2011-11-11/386c7218162c145f5f9e1ff7f558a3fbb66c37c5.
- - Add a dedicated function to parse the values of toggles. Reduces duplicated
- code in load_config() and provides better error handling. Invalid or missing
- toggle values are now a fatal error instead of being silently ignored.
- - Terminate HTML lines in static error messages with \n instead of \r\n.
- - Simplify cgi_error_unknown() a bit.
- - In LogPutString(), don't bother looking at pszText when not
- actually logging anything.
- - Change ssplit()'s fourth parameter from int to size_t.
- Fixes a clang complaint.
- - Add a warning that the statistics currently can't be trusted.
- Mention Privoxy-Log-Parser's --statistics option as
- an alternative for the time being.
- - In rfc2553_connect_to(), start setting cgi->error_message on error.
- - Change the expected status code returned for http://p.p/die depending
- on whether or not FEATURE_GRACEFUL_TERMINATION is available.
- - In cgi_die(), mark the client connection for closing.
- If the client will fetch the style sheet through another connection
- it gets the main thread out of the accept() state and should thus
- trigger the actual shutdown.
- - Add a proper CGI message for cgi_die().
- - Don't enforce a logical line length limit in read_config_line().
- - Slightly refactor server_last_modified() to remove useless gmtime*() calls.
- - In get_content_type(), also recognize '.jpeg' as JPEG extension.
- - Add '.png' to the list of recognized file extensions in get_content_type().
- - In block_url(), consistently use the block reason "Request blocked by Privoxy"
- In two places the reason was "Request for blocked URL" which hides the
- fact that the request got blocked by Privoxy and isn't necessarily
- correct as the block may be due to tags.
- - In listen_loop(), reload the configuration files after accepting
- a new connection instead of before.
- Previously the first connection that arrived after a configuration
- change would still be handled with the old configuration.
- - In chat()'s receive-data loop, skip a client socket check if
- the socket will be written to right away anyway. This can
- increase the transfer speed for unfiltered content on fast
- network connections.
- - The socket timeout is used for SOCKS negotiations as well which
- previously couldn't timeout.
- - Don't keep the client connection alive if any configuration file
- changed since the time the connection came in. This is closer to
- Privoxy's behaviour before keep-alive support for client connection
- has been added and also less confusing in general.
- - Treat all Content-Type header values containing the pattern
- 'script' as a sign of text. Reported by pribog in #3134970.
-
-- Action file improvements:
- - Moved the site-specific block pattern section below the one for the
- generic patterns so for requests that are matched in both, the block
- reason for the domain is shown which is usually more useful than showing
- the one for the generic pattern.
- - Remove -prevent-compression from the fragile alias. It's no longer
- used anywhere by default and isn't known to break stuff anyway.
- - Add a (disabled) section to block various Facebook tracking URLs.
- Reported by Dan Stahlke in #3421764.
- - Add a (disabled) section to rewrite and redirect click-tracking
- URLs used on news.google.com.
- Reported by Dan Stahlke in #3421755.
- - Unblock linuxcounter.net/.
- Reported by Dan Stahlke in #3422612.
- - Block 'www91.intel.com/' which is used by Omniture.
- Reported by Adam Piggott in #3167370.
- - Disable the handle-as-empty-doc-returns-ok option and mark it as deprecated.
- Reminded by tceverling in #2790091.
- - Add ".ivwbox.de/" to the "Cross-site user tracking" section.
- Reported by Nettozahler in #3172525.
- - Unblock and fast-redirect ".awin1.com/.*=http://".
- Reported by Adam Piggott in #3170921.
- - Block "b.collective-media.net/".
- - Widen the Debian popcon exception to "qa.debian.org/popcon".
- Seen in Debian's 05_default_action.dpatch by Roland Rosenfeld.
- - Block ".gemius.pl/" which only seems to be used for user tracking.
- Reported by johnd16 in #3002731. Additional input from Lee and movax.
- - Disable banners-by-size filters for '.thinkgeek.com/'.
- The filter only seems to catch pictures of the inventory.
- - Block requests for 'go.idmnet.bbelements.com/please/showit/'.
- Reported by kacperdominik in #3372959.
- - Unblock adainitiative.org/.
- - Add a fast-redirects exception for '.googleusercontent.com/.*=cache'.
- - Add a fast-redirects exception for webcache.googleusercontent.com/.
- - Unblock http://adassier.wordpress.com/ and http://adassier.files.wordpress.com/.
-
-- Filter file improvements:
- - Let the yahoo filter hide '.ads'.
- - Let the msn filter hide overlay ads for Facebook 'likes' in search
- results and elements with the id 's_notf_div'. They only seem to be
- used to advertise site 'enhancements'.
- - Let the js-events filter additionally disarm setInterval().
- Suggested by dg1727 in #3423775.
-
-- Documentation improvements:
- - Clarify the effect of compiling Privoxy with zlib support.
- Suggested by dg1727 in #3423782.
- - Point out that the SourceForge messaging system works like a black
- hole and should thus not be used to contact individual developers.
- - Mention some of the problems one can experience when not explicitly
- configuring an IP addresses as listen address.
- - Explicitly mention that hostnames can be used instead of IP addresses
- for the listen-address, that only the first address returned will be
- used and what happens if the address is invalid.
- Requested by Calestyo in #3302213.
-
-- Log message improvements:
- - If only the server connection is kept alive, do not pretend to
- wait for a new client request.
- - Remove a superfluous log message in forget_connection().
- - In chat(), properly report missing server responses as such
- instead of calling them empty.
- - In forwarded_connect(), fix a log message nobody should ever see.
- - Fix a log message in socks5_connect(), a failed write operation
- was logged as failed read operation.
- - Let load_one_actions_file() properly complain about a missing
- '{' at the beginning of the file.
- Simply stating that a line is invalid isn't particularly helpful.
- - Do not claim to listen on a socket until Privoxy actually does.
- Patch submitted by Petr Pisar #3354485
- - Prevent a duplicated LOG_LEVEL_CLF message when sending out
- the "no-server-data" response.
- - Also log the client socket when dropping a connection.
- - Include the destination host in the 'Request ... marked for
- blocking. limit-connect{...} doesn't allow CONNECT ...' message
- Patch submitted by Saperski in #3296250.
- - Prevent a duplicated log message if none of the resolved IP
- addresses were reachable.
- - In connect_to(), do not pretend to retry if forwarded-connect-retries
- is zero or unset.
- - When a specified user or group can't be found, put the name in
- single-quotes when logging it.
- - In rfc2553_connect_to(), explain getnameinfo() errors better.
- - Remove a useless log message in chat().
- - When retrying to connect, also log the maximum number of connection
- attempts.
- - Rephrase a log message in compile_dynamic_pcrs_job_list().
- Divide the error code and its meaning with a colon. Call the pcrs
- job dynamic and not the filter. Filters may contain dynamic and
- non-dynamic pcrs jobs at the same time. Only mention the name of
- the filter or tagger, but don't claim it's a filter when it could
- be a tagger.
- - In a fatal error message in load_one_actions_file(), cover both
- URL and TAG patterns.
- - In pcrs_strerror(), properly report unknown positive error code
- values as such. Previously they were handled like 0 (no error).
- - In compile_dynamic_pcrs_job_list(), also log the actual error code as
- pcrs_strerror() doesn't handle all errors reported by pcre.
- - Don't bother trying to continue chatting if the client didn't ask for it.
- Reduces log noise a bit.
- - Make two fatal error message in load_one_actions_file() more descriptive.
- - In cgi_send_user_manual(), log when rejecting a file name due to '/' or '..'.
- - In load_file(), log a message if opening a file failed.
- The CGI error message alone isn't too helpful.
- - In connection_destination_matches(), improve two log messages
- to help understand why the destinations don't match.
- - Rephrase a log message in serve(). Client request arrival
- should be differentiated from closed client connections now.
- - In serve(), log if a client connection isn't reused due to a
- configuration file change.
- - Let mark_server_socket_tainted() always mark the server socket tainted,
- just don't talk about it in cases where it has no effect. It doesn't change
- Privoxy's behaviour, but makes understanding the log file easier.
-
-- configure:
- - Added a --disable-ipv6-support switch for platforms where support
- is detected but doesn't actually work.
- - Do not check for the existence of strerror() and memmove() twice
- - Remove a useless test for setpgrp(2). Privoxy doesn't need it and
- it can cause problems when cross-compiling.
- - Rename the --disable-acl-files switch to --disable-acl-support.
- Since about 2001, ACL directives are specified in the standard
- config file.
- - Update the URL of the 'Removing outdated PCRE version after the
- next stable release' posting. The old URL stopped working after
- one of SF's recent site "optimizations". Reported by Han Liu.
-
-- Privoxy-Regression-Test:
- - Added --shuffle-tests option to increase the chances of detection race conditions.
- - Added a --local-test-file option that allows to use Privoxy-Regression-Test without Privoxy.
- - Added tests for missing socks4 and socks4a forwarders.
- - The --privoxy-address option now works with IPv6 addresses containing brackets, too.
- - Perform limited sanity checks for parameters that are supposed to have numerical values.
- - Added a --sleep-time option to specify a number of seconds to
- sleep between tests, defaults to 0.
- - Disable the range-requests tagger for tests that break if it's enabled.
- - Log messages use the ISO 8601 date format %Y-%m-%d.
- - Fix spelling in two error messages.
- - In the --help output, include a list of supported tests and their default levels.
- - Adjust the tests to properly deal with FEATURE_TOGGLE being disabled.
-
-- Privoxy-Log-Parser:
- - Perform limited sanity checks for command line parameters that
- are supposed to have numerical values.
- - Implement a --unbreak-lines-only option to try to revert MUA breakage.
- - Accept and highlight: Added header: Content-Encoding: deflate
- - Accept and highlight: Compressed content from 29258 to 8630 bytes.
- - Accept and highlight: Client request arrived in time on socket 21.
- - Highlight: Didn't receive data in time: a.fsdn.com:443
- - Accept log messages with ISO 8601 time stamps, too.
-
-- uagen:
- - Bump generated Firefox version to 8.0.
- - Only randomize the release date if the new --randomize-release-date
- option is enabled. Firefox versions after 4 use a fixed date string
- without meaning.
-
-*** Version 3.0.17 Stable ***
-
-- Fixed last-chunk-detection for responses where the body was small
- enough to be read with the headers, 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
- cannot-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 ***
-
-- 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. Donations
- are still welcome too: http://www.privoxy.org/faq/general.html#DONATE
-
-*** Version 3.0.12 ***
-
-- The socket-timeout option now also works on platforms whose
- select() implementation modifies the timeout structure.
- Previously the timeout was triggered even if the connection
- didn't stall. Reported by cyberpatrol.
-- The Connection: keep-alive code properly deals with files
- larger than 2GB. Previously the connection was closed too
- early.
-- The content length for files above 2GB is logged correctly.
-- The user-manual directive on the show-status page links to
- the documentation location specified with the directive,
- not to the Privoxy website.
-- When running in daemon mode, Privoxy doesn't log anything
- to the console unless there are errors before the logfile
- has been opened.
-- The show-status page prints warnings about invalid directives
- on the same line as the directives themselves.
-- Fixed several justified (but harmless) compiler warnings,
- mostly on 64 bit platforms.
-- The mingw32 version explicitly requests the default charset
- to prevent display problems with some fonts available on more
- recent Windows versions. Patch by Burberry.
-- The mingw32 version uses the Privoxy icon in the alt-tab
- windows. Patch by Burberry.
-- The timestamp and the thread id is omitted in the "Fatal error"
- message box on mingw32.
-- Fixed two related mingw32-only buffer overflows. Triggering
- them required control over the configuration file, therefore
- this isn't seen as a security issue.
-- In verbose mode, or if the new option --show-skipped-tests
- is used, Privoxy-Regression-Test logs skipped tests and the
- skip reason.
-
-*** 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 3.0.10 ***
-
-- Ordinary configuration file changes no longer cause program
- termination on OS/2 if the name of the logfile hasn't been
- changed as well. This regression probably crept in with the
- logging improvements in 3.0.7. Reported by Maynard.
-- The img-reorder filter is less likely to mess up JavaScript code in
- img tags. Problem and solution reported by Glenn Washburn in #2014552.
-- The source tar ball now includes Privoxy-Log-Parser,
- a syntax-highlighter for Privoxy logs. For fancy screenshots see:
- http://www.fabiankeil.de/sourcecode/privoxy-log-parser/
- Documentation is available through perldoc(1).
-
-*** Version 3.0.9 beta ***
-
-- Added SOCKS5 support (with address resolution done by
- the SOCKS5 server). Patch provided by Eric M. Hopper.
-- The "blocked" CGI pages include a block reason that was
- provided as argument to the last-applying block action.
-- If enable-edit-actions is disabled (the default since 3.0.7 beta)
- the show-status page hides the edit buttons and explains why.
- Previously the user would get the "this feature has been disabled"
- message after using the edit button.
-- Forbidden CONNECT requests are treated like blocks by default.
- The now-pointless treat-forbidden-connects-like-blocks action
- has been removed.
-- Not enabling limit-connect now allows CONNECT requests to all ports.
- In previous versions it would only allow CONNECT requests to port 443.
- Use +limit-connect{443} if you think you need the old default behaviour.
-- The CGI editor gets turned off after three edit requests with invalid
- file modification timestamps. This makes life harder for attackers
- who can leverage browser bugs to send fake Referers and intend to
- brute-force edit URLs.
-- Action settings for multiple patterns in the same section are
- shared in memory. As a result these sections take up less space
- (and are loaded slightly faster). Problem reported by Franz Schwartau.
-- Linear white space in HTTP headers will be normalized to single
- spaces before parsing the header's content, headers split across
- multiple lines get merged first. This should prevent problems like:
- * letting the session-cookies-only action slip
- some Cookies through unmodified,
- * only suppressing the first line of a header,
- thus creating an invalid one, and
- * to incorrectly block headers with valid timestamps
- that weren't properly recognized.
- Headers that could trigger these problems are unlikely to appear
- in "normal" web traffic, but could be intentionally generated to
- fool some of Privoxy's header parsers.
-- Host information is gathered outside the main thread so it's less
- likely to delay other incoming connections if the host is misconfigured.
-- New config option "hostname" to use a hostname other than
- the one returned by the operating system. Useful to speed-up responses
- for CGI requests on misconfigured systems. Requested by Max Khon.
-- The CGI editor supports the "disable all filters of this type"
- directives "-client-header-filter", "-server-header-filter",
- "-client-header-tagger" and "-server-header-tagger".
-- Fixed false-positives with the link-by-url filter and URLs that
- contain the pattern "/jump/".
-- The less-download-windows filter no longer messes
- "Content-Type: application/x-shockwave-flash" headers up.
-- In the show-url-info page's "Final results" section active and
- inactive actions are listed separately. Patch provided by Lee.
-- The GNUmakefile supports the DESTDIR variable. Patch for
- the install target submitted by Radoslaw Zielinski.
-- Embedding the content of configuration files in the show-status
- page is significantly faster now. For a largish action file (1 MB)
- a speedup of about 2450 times has been measured. This is mostly
- interesting if you are using large action files or regularly use
- Privoxy-Regression-Test while running Privoxy through Valgrind,
- for stock configuration files it doesn't really matter.
-- If zlib support is unavailable and there are content
- filters active but the prevent-compression action is disabled,
- the show-url-info page includes a warning that compression
- might prevent filtering.
-- The show-url-info page provides an OpenSearch Description that
- allows to access the page through browser search plugins.
-- Custom client-header filters that rewrite the request line
- incorrectly no longer cause Privoxy to crash. Reported by din_a4.
-- The obsolete kill-popups action has been removed as the
- PCRS-based popup filters can do the same and are slightly
- less unreliable.
-- The inspect-jpegs action has been removed.
-- The send-wafer and send-vanilla-wafer actions have been removed.
- They weren't particular useful and their behaviour could be emulated
- with add-header anyway.
-- Privoxy-Regression-Test has been significantly improved.
-- Most sections in the default.action file contain tests for
- Privoxy-Regression-Test to verify that they are working as intended.
-- Parts of Privoxy have been refactored to increase maintainability.
-- Building with zlib (if available) is done by default.
-
-*** Version 3.0.8 ***
-
-- Fixed a small memory leak when listen-address only specifies the port.
-- The source tar balls now include Privoxy-Regression-Test which
- (upon other things) can be used to automatically detect some
- packaging problems. Packagers are welcome to give it a try.
-- Reverted a change in 3.0.7 that caused path patterns to be checked
- even if the host pattern match already failed. While this doesn't
- noticeable affect the performance, it makes it less likely to run
- out of stack space with overly-complex path patterns the user might
- have added.
-- Updated the msn, yahoo and google filters to work as advertised again.
-- The warning message shown by the show-status CGI page is easier to
- understand. Previously it wasn't clear that the error message
- is shown below the invalid directive. (Reported by Lee)
-- When regenerating Content-Disposition headers the more common
- spelling is used for the name. Previously it was written without caps.
-- Less confusing log message if the content type isn't overwritten
- because force-text-type wasn't used but the old type doesn't look
- like content that would be filtered normally.
-- Better log messages if the user tries to execute filters that
- don't exist.
-- Treat the non-standard Request-Range headers like standard range
- headers and suppress them if content filtering is enabled.
-- Prevent the log messages for CONNECT requests to unacceptable
- ports from printing the limit-connect argument as [null] if
- limit-connect hasn't been explicitly enabled.
-- Don't disable the mingw32 log window if the logfile directive
- isn't used. While it was an intentional change in 3.0.7 at least
- one user perceived it as a regression and the same effect can
- be achieved by disabling all debug directives.
-- Fixed two minor problems related to the win32 build process: a css
- file was not being in the installer and the trustfile comment in the
- config.txt referenced a nonexisting file
-- Minor documentation fixes.
-
-*** Version 3.0.7 beta ***
-
-- Added zlib support to filter content with gzip and deflate
- encoding. (Patch provided by Wil Mahan)
-- Dedicated filters and actions are used for header filtering.
- "filter-client-headers" and "filter-client-headers" are no longer
- supported, use server-header-filter{} and client-header-filter{}
- instead.
-- Tags can be used to change actions based on HTTP headers.
-- New server-header filter: less-download-windows.
-- New client-header taggers: css-requests, image-requests,
- client-ip-address, http-method, allow-post, complete-url,
- user-agent and privoxy-control.
-- New server-header taggers: content-type and privoxy-control.
-- The forward-override{} action allows to change the forwarding
- settings through the action files, for example based on client
- headers like the User-Agent, or the request origin.
-- Socks errors are no longer handled by the CGI page for
- DNS resolution failures.
-- CGI pages use favicons to signal whether they are error
- or control pages. This is useful if you rely heavily on
- browser tabs.
-- The show-url-info CGI page shows the forwarding settings.
-- "Crunch!" log messages (used when Privoxy answers requests
- by itself) now also contain the reason.
-- Allow to rewrite the request destination behind the client's back.
-- Fix socks requests on big-endian platforms. Patch provided by Song Weijia.
-- Fixes possible deadlocks and crashes on OpenBSD.
- Patch provided by Ralf Horstmann.
-- The CGI action editor allows to edit actionfiles with previously
- forbidden characters like dots.
-- New trust entries are saved with a comment that contains the
- trusted referring URL (Suggested by Daniel Griscom).
-- Filter descriptions are HTML encoded automatically.
-- New config option "split-large-forms" to work
- around a browser bug that caused IE6 and IE7 to ignore
- the Submit button on the edit-actions-for-url CGI page.
-- New config option "allow-cgi-request-crunching" to allow
- requests for Privoxy's CGI pages to be blocked, redirected
- or (un)trusted like ordinary requests.
-- Empty filter files no longer interrupt the filtering process
- prematurely and are correctly listed on the show-status CGI page.
-- New config option "accept-intercepted-requests" to combine
- Privoxy with any packet filter to build an intercepting proxy
- for HTTP/1.1 requests (and for HTTP/1.0 requests with Host header set).
-- fast-redirects{} catch redirects to https URLs as well.
-- redirect{s@foo@bar@} can be used to redirect to a rewritten
- version of the original URL.
-- Trap unsupported gopher proxy requests.
-- Fixed a bug in the User Manual delivery on Windows
- (mingw32 only). Images now show up correctly and HTML
- pages are no longer padded with garbage data.
-- Fixed several minor memory leaks, most of them discovered with Valgrind.
-- Only unlink the pidfile if it's actually used.
-- Retries after connection problems with forced requests
- aren't blocked again.
-- On Unix SIGABRT causes a core dump as expected and is no
- longer treated as normal shutdown signal.
-- The "access denied" CGI page is more descriptive and
- allows retries to circumvent the referrer check.
-- Updated PCRS to handle unexpected PCRE errors properly.
- Fixed crashes that could occur if Privoxy was build
- with external PCRE versions newer than Privoxy's internal
- one. (Reported by Chung-chieh Shan)
-- Fixed crashes with null bytes in PCRS replacement strings
- (Patch provided by Felix Gröbert).
-- Fixed crashes with header time randomization on mingw32.
-- The CGI style sheet is no longer delivered if the referring
- page isn't a Privoxy CGI page. This prevents a JavaScript-based
- Privoxy detection "attack". Note that detecting Privoxy is
- still possible through other ways and Privoxy was never intended
- to be invisible anyway.
-- Added support for AmigaOS 4, fixed build for AmigaOS 3.x.
-- The show-url-info CGI page displays a warning if Privoxy
- is currently toggled off.
-- The show-status CGI page suppresses the edit button
- for action files if Privoxy has no write access.
-- Most CGI error pages react properly to HEAD requests.
-- Requests with RFC 3253 HTTP methods (used by Subversion)
- are accepted. (Patch provided by Petr Kadlec)
-- New config option "templdir" to change the location
- of the CGI templates to make sure customized templates
- aren't "updated".
-- Better handling of "HTTP/1.1 100 Continue" responses.
-- The background of the PNG pattern is transparent.
-- Fixed XML syntax errors caused by banners-by-size and banners-by-url.
-- Fixed crashes and possible action file corruptions
- when lines containing hashes are written through the CGI editor.
-- Supports dynamic filters which can contain variables.
-- Supports tags to change the actions based on client or server headers.
-- Incorrect actions are logged before program termination.
-- The "actionsfile" syntax in the configuration file is consistent
- with the rest of the configuration options and requires the
- whole file name. This is an incompatible change, if you use
- an old configuration file you might have to append ".action"
- to your "actionsfile" directives.
-- With the configuration file option "enforce-blocks" the
- "go there anyway" mechanism can be disabled without recompiling
- Privoxy.
-- More precise error messages in case of incorrect acl syntax.
-- Logs a warning if filtering is enabled but impossible due
- to lack of zlib support or use of the prevent-compression action.
-- Less noisy handling of Cookie:" and "Connection:" headers.
-- Improved error messages in case of connection problems.
-- Fix a command-line-parsing bug that was introduced before 3.0.5
- beta and caused Privoxy to treat the last argument as configuration
- file if no configuration file was specified.
-- Treat unknown command line options as fatal errors instead
- of silently ignoring them.
-- Use string functions with length checks more often.
-- Don't log CONNECT requests twice.
-- Allow to log the source address for ACL-related connection drops.
-- Don't ignore applying filters if the server didn't
- specify a Content-Type. Bug reported by Amuro Namie.
-- Rejected CONNECT requests are logged with log level info
- (enabled by default) and the reason for the block.
-- New command line option "--pre-chroot-nslookup hostname" to
- intialize the resolver library before chroot'ing. On some systems this
- reduces the number of files that must be copied into the chroot tree.
- (Patch provided by Stephen Gildea)
-- Fix a long-standing memory corruption bug that could cause
- Privoxy to overwrite a single byte in memory it didn't explicitly
- allocate (but that probably was allocated anyway due to bucket size).
-- Send template-based CGI pages as HTTP/1.1 unless the client
- asked for HTTP/1.0.
-- Let the first line in connection established responses
- end in \r\n as required by RFC1945. Reported by Bert van Leeuwen.
-- If no log file has been specified, disable logging instead of logging
- to stderr.
-- Don't block stderr when in daemon mode.
-- Ignore missing zero-chunks when filtering chunk-encoded content.
- Earlier Privoxy versions would buffer and then forward the content
- unmodified which caused some browsers to simply show empty pages.
-- Fix double free in cgi_edit_actions_list(). Reported by Venustech AD-LAB.
-- The code to add X-Forwarded-For headers when the hide-forwarded-for-headers
- action isn't being used has been removed.
-- Fixed trustfile feature which previously didn't work without FEATURE_TOGGLE.
- Reported by Lee.
-- Minor code clean-ups, filter and action file updates.
- (Some of them reported by Davide Alberani, Markus Elfring,
- Stefan Huehner and Adam Piggott)
-
-*** Version 3.0.6 ***
-
-- New content filters: no-ping, google, msn, yahoo and blogspot.
-- New header filters: x-httpd-php-to-html, html-to-xml, xml-to-html
- and hide-tor-exit-notation.
-- The special header "X-Filter: No" now disables header filtering as well.
-- Improved the filters img-reorder, js-annoyances, webbugs,
- banners-by-size, banners-by-link and ie-exploits to make them
- less likely to break anything.
-- Removed outdated URL patterns in default.action and added new ones.
-- Added redirection from http://p.p/user-manual to http://p.p/user-manual/
-- Changed webinterface default values for hide-user-agent, hide-referrer
- and set-image-blocker.
-
-*** Version 3.0.5 beta ***
-
-- Windows version can be installed/started as a service.
-- Windows icon stays blue when Privoxy is idle, green when busy.
-- Integrated Fabian Keil's extensive patch. See:
- http://www.fabiankeil.de/sourcecode/privoxy/. Includes the
- following new or significantly improved actions (among many
- other improvements):
-
- content-type-overwrite{}

-- Trap unsupported FTP requests.
-- Let text/xml be filtered.
-- Numerous updates to default.action
-- Increase the compiled in limit of trusted referrers from 64 to 512
- (for trustfile users).
-
-*** Version 3.0.3 ***
-
-- Fixed yet another two memory leaks. Process growth seems stopped now.
-- Further tightened security against malicious toggle-off links.
-- Excluded text/plain MIME types from filtering. This fixes a
- couple of client-crashing, download corruption and
- Privoxy performance issues, whose root cause lies in
- web servers labelling content of unknown type as text/plain.
-- Assorted fixes for POSIX compliance, signal handling, graceful
- termination, compiler warnings, OSX support, Win32 systray,
- error logging, hostname wildcards, correct detection of NetBSD.
-- Workarounds for client (iTunes etc) and server (PHP < 4.2.3) bugs
- including the notorious "blank page" problem.

- html-annoyances, content-cookies and fun filters
- - Replaced filter "popups" by choice between two modes:
- - "unsolicited-popups" tries to catch only the unsolicited ones
- - "all-popups" tries to kill them all (as before)
- - New filter "tiny-textforms" Help those tiny or hard-wrap textareas.
- - New filter "jumping-windows" that prevents windows from resizing
- and moving themselves
- - New filter "demoronizer" which fixes MS's abuse of std charsets
- (common cases anyway).
- - Replaced "nimda" with more general "ie-exploits" filter in which
- all filters for exploits shall be collected
-- Improved cookie logging
-- Rewrote make install target. Added uninstall and install-strip

-- Fix for the Netscape bug reintroduced in 2.9.9.
-- make should now abort if gmake (GNU make) not present.
-- Many other minor bugfixes
-- Start a ChangeLog :)

-
-*** Version 2.9.3 pre-Alpha Changes ***
-
-- Amiga support (completely untested by me - I don't have an Amiga)
-- "tinygif 3" support (redirects blocked images to a specified URL, so
-the browser doesn't have to load and cache many copies of the same
-image).
-- one case where there were both local and global "referrer" variables
-(yuck!) clarified by renaming the local one to "refer".
-- Fixed some places where close() was used instead of close_socket().
-Thanks to Jörg Strohmayer (joergs at users.sourceforge.net) for these.
-- Temporary hack to get FORCE_LOAD to work with IE. I just lowercased the
-FORCE_LOAD_PREFIX. Needs fixing properly.
-- Most URLs hardcoded into Junkbuster were changed to go through a script
-e.g. http://ijbswa.sourceforge.net/redirect.php?v=2.9.3&to=faq
-The only other URLs left are the GNU GPL:
- http://www.fsf.org/copyleft/gpl.html
-and the home page:
- http://ijbswa.sourceforge.net/
-... and various URLs which will be intercepted by Junkbuster anyway.
-TODO: Still need to do something with the URLs in Junkbuster Corp's
-copyright/trademark notice on the bottom of the show-proxy-args page.
-- PCRE or GNU Regex is now a #define option.
-
-
-*** Version 2.9.2 pre-Alpha Changes ***
-
-- Andreas applied the latest version of the FORCE patch.
-
-
-*** Version 2.9.1 pre-Alpha Changes ***
-
-- in parsers.c, fixed two #ifdef FORCE to #ifdef FORCE_LOAD
-(BTW: I think FORCE is precise enough, since loading remote
-data is the whole purpose of a proxy..)
-- Set the FORCE_PREFIX (back) to 'IJB-FORCE-LOAD-'. While 'noijb.'
-is more elegant and looks like a hostname in the URL, it doesn't
-make clear to the inexperienced user that the proxy is bypassed. It
-also has a higher name collision risk.
-- Filled in the function header templates for my functions in
-parsers.c (again). They obviously got lost in our current
-patch war ;-)
-- Cut the credit for the §-referrer-option from the config file,
-that Stefan had placed there.
-- Improved the re_filterfile
-
-
-*** Version 2.9.0 pre-Alpha Changes ***
-
-- Now use PCRE, not GNU REGEX. I have not yet had chance to check the
-syntax of the block/image/cookie file to ensure that they match what
-is expected - however they seem to work.
-- Replaced "configure" script with one generated by "autoconf". Also
-use a header "config.h" (was ijbconfig.h in my previous release) for
-the #defines. "config.h" is now generated with "autoheader" from
-"acconfig.h" and "configure.in". (Note that to install you do not
-need autoconf or autoheader - just run "./configure".)
-To see command-line options, run "./configure --help".
-This is my first ever autoconf script, so it has some rough edges
-(how PCRE is handled is the roughest).
-- Error logging code replaced with new module errlog.c, based on the
-one from JunkbusterMT (but with the threading code removed).
-- Most of Rodney's 0.21 and 0.21A patches applied. (Marked *). I did not
-apply all of these, since I had already independently done conditional
-popup file, conditional image file, and integration of popup code.
-- ACL, Jar and trust files conditionally compiled.
-- New source file headers.
-- Various cosmetic changes. (But I have not consistently ordered the
-config files - I think that's worthwhile, but it's 1am and I want to
-get this released!)
-- RCS tags on .h files.
-- RCS tags are const char[] rather than const char *. (Saves 4 bytes
-per tag ;-)
-- VC++ project files renamed to vc_junkbuster.*.
-- show-proxy-args now shows status of all conditionals, not just REGEX
-- Various functions moved around. Most notably all the system-specific
-sockets code which was spread between jcc.c, bind.c, and connect.c,
-has been moved to "jbsockets.c". The non-system-specific code from
-connect.c and socks4.c has been movet to "gateway.c". Also, the
-config file loader and the global variables it writes to have been
-moved to "loadcfg.c". (Maybe this should go into loaders.c?)
-And candidate for the "worst filename ever" award is "miscutil.c",
-which contains, well, miscellaneous utility functions like zalloc.
-(Suggestions for a better name for this file are welcome!)
-- Loaders now use a common function to read a line and skip comments,
-and this function also stores the proxy_args.
-- Added ./junkbuster --help (Not for Win32 GUI)
-- Added ./junkbuster --version (Not for Win32 GUI)
-- Win32 resources are now all marked as "U.S. English", rather than
-being a mix of "U.S. English", "U.K. English" and "Irish English".
-- Version number changes to 2.9.0
