ChangeLog for Privoxy
--------------------------------------------------------------------
+*** 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.
+ - 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.
+ - Let fatal_error() write to the logfile right away, before showing the
+ Windows-specific error message which blocks until the user acknowledges
+ it, thus complicating automatic error detection.
+ Reported by Adriaan in #3593603.
+ - Fix the --disable-ipv6-support configure option for the Windows platform.
+ - In socks5_connect(), do not try to print a negative number of socks
+ response bytes if the read() for the socks5 negotiation failed
+ completely. It's an API violation and can trigger an assert() in debug
+ builds with "debug 2" enabled. Except for the assert(), log_error()
+ already handled negative %N values gracefully so this commit only makes a
+ difference for debug builds.
+ - Fix an assertion that could cause debug builds to abort() if a filter
+ contained nul bytes in the replacement text.
+ - 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.
+
+- 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 each
+ request that Privoxy acts upon.
+ - New directive client-header-order can be used to forward client headers in
+ a different order than that in which they arrived.
+ - New directive tolerate-pipelining can be used to enable 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 lets Privoxy exit after checking whether or not
+ the configuration seems valid. The limitations noted in TODO #22 and #23
+ still apply. Logging the problem to the logfile if one is configured and
+ --no-daemon isn't used could be considered non-intuitive and might also
+ clobber messages emitted by an already running instance. Based on a patch
+ by Ramkumar Chinchani.
+ - Add limit-cookie-lifetime{} action. It can be used to let cookies expire
+ before the end of the session. limit-cookie-lifetime{0} creates session
+ cookies and can thus replace the session-cookies-only action in the future.
+ Idea originally 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 receving 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 in
+ accept_connection(). This should further reduce the chances of the client
+ getting an incomplete response, even though Privoxy wrote it in its
+ entirety to the socket.
+ - Move several variable declarations to the beginning of their code block.
+ It's how we usually do it and is apparently also required when compiling
+ with gcc 2.95. Initial patch submitted by Simon South in #3564815.
+ - Optionally let parse_header_time() 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:
+ http://www.freebsd.org/cgi/query-pr.cgi?pr=173421
+ - Attempt to work around (or at least reduce the) video playback issues with
+ various Apple clients as reported in #3426305. In client_range(), let
+ headers pass if the range starts at the beginning.
+ - 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.
+
+- Action file improvements:
+ - Remove the comment that indicated that updated versions of this file are
+ released on their own.
+ - Block 'optimize.indieclick.com/' and 'optimized-by.rubiconproject.com/'
+ - Unblock 'adjamblog.wordpress.com/' and 'adjamblog.files.wordpress.com/'.

+ - 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 and
+ having to toggle Privoxy off to not show the icon makes no sense anyway.
+ Reported by Zeno Kugy in #3596395.
+ - Add the DNT header to the client-header-order example.
+ - 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. While
+ at it, use an upper-case first character which is more consistent with the
+ other log messages.
+
+- 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 ouside 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.
+ - Update an error message that still tried to print directive_hash as long
+ - 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 potentiallly larger
+ type is at best useless.
+ - Use privoxy_tolower() instead of vanilla tolower() with manual casting of
+ the argument.
+
+- Privoxy-Regression-Test:
+ - Various grammar and spelling corrections in documentation and code.
+ - Additional tests for range requests with filtering enabled.
+ - Tests with mostly invalid range request.
+ - Log to STDOUT instead of STDERR.
+ - 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.
+ - Fix comment typos.
+ - 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.
+ - Include the Privoxy version in the output.
+
+- Privoxy-Log-Parser:
+ - Improve the --statistics performance by skipping sanity checks for input
+ that shouldn't affect the results anyway. In my non-scientific benchmarks
+ this reduces the runtime by about 45%. Also add a --strict-checks option
+ that enables some of the checks again, just in case anybody cares.
+ - Accept and highlight: Stopping to watch the client socket. There's already
+ another request waiting.
+ - Cleanup variable initialization in print_non_clf_message().
+ - Properly highlight the new log messages from get_request_line().
+ - Let get_percentage() show 0 of x as 0% even if x is 0 as well.
+ - Accept and ignore: Enlisting (sorted|left-over) header ...
+ - Accept the shiny new LOG_LEVEL_ACTIONS.
+ - Accept and highlight: Closing client socket 5. Keep-alive: 0, Socket
+ alive: 1. Data available: 0.
+ - Stop suppressing messages about accepted client connections and highlight
+ them properly.
+ - Accept and highlight: Accepted connection from 10.0.0.1 on socket 5.
+ - Accept and highlight: Continuing buffering server headers from socket 5.
+ Bytes most recently read: 498.
+ - Accept and highlight: Client request 4 arrived in time on socket 7.
+ - Accept and highlight: Closing client socket 8. Keep-alive: 1. Socket
+ alive: 0. Data available: 0. Configuration file change detected: 0.
+ Requests received: 11.
+ - Accept and highlight: Drained 180 bytes before closing socket 6.
+ - Accept and highlight the extended log message for client sockets.
+ - Accept and highlight: Tainting client socket 7 due to unread data.
+ - Accept and highlight: Optimistically sending 318 bytes of client
+ headers intended for www.privoxy.org.
+ - Accept and highlight: Client request 8 has been pipelined on socket 7 and
+ the socket is still alive.
+ - Accept: There better be a request body.
+ - Accept and highlight: Shifting 360 pipelined bytes by 360 bytes.
+ - Accept and highlight: Multiple Content-Type headers detected. Removing and
+ ignoring: Content-Type: text/html.
+
+- uagen:
+ - Bump generated Firefox version to 16.
+
+- CGI interface improvements & bug fixes:
+ - Remove an unreasonable parameter limit in parse_cgi_parameters(). 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@.
+ - Catch ssplit() failures in parse_cgi_parameters().
+ - Deal with unsupported methods sent to the CGI pages by discarding any
+ data following the headers.
+
+- 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.
+ - Prevent completely empty lines in configure and try to unfold
+ unintentional line breaks.
+ - Let the config-file target optimistically update the original. Most of the
+ issues are fixed now and it makes diffing with git easier.
+ - 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.
+ - Several improvements for clarity, diffability and logic.
+
+ *** 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 content was small
- enough to be read with the body, causing Privoxy to wait for the
- end of the content until the server closed the connection.
- Reported by "Karsten" in #3028326.

+ 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.
- 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
- 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.
+ - In cgi_show_url_info(), don't forget to prefix URLs that only contain

- Show the 404 CGI page if cgi_send_user_manual() is called while
local user manual delivery is disabled.
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
+ - 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@
+ Reported by Mathias Homann in #3101419 and by Patrick on ijbswa-users@.
- Documentation improvements:
- Explicitly mention how to match all URLs.
- 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.
- - Also gather statistics for ressources, methods, and HTTP versions
- used by the client.
- 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.
- In log_error(), assert that ival and sval have reasonable values.
There's no reason not to abort() if they don't.
- Remove an incorrect cgi_error_unknown() call in a
- cannnot-happen-situation in send_crunch_response().
+ 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.
