- Release</a></h1>
-
- <p><span class="APPLICATION">Privoxy 3.0.20</span> is a beta release. The
- changes since 3.0.19 stable are:</p>
-
- <ul>
- <li>
- <p>Bug fixes:</p>
-
- <ul>
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>The default-server-timeout and socket-timeout directives
- accept 0 as valid value.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>Fix the compilation on Windows when configured without IPv6
- support.</p>
- </li>
-
- <li>
- <p>Fix an assertion that could cause debug builds to abort() in
- case of socks5 connection failures with "debug 2" enabled.</p>
- </li>
-
- <li>
- <p>Fix an assertion that could cause debug builds to abort() if a
- filter contained nul bytes in the replacement text.</p>
- </li>
- </ul>
- </li>
-
- <li>
- <p>General improvements:</p>
-
- <ul>
- <li>
- <p>Significantly improved keep-alive support for both client and
- server connections.</p>
- </li>
-
- <li>
- <p>New debug log level 65536 which logs all actions that were
- applied to the request.</p>
- </li>
-
- <li>
- <p>New directive client-header-order to forward client headers in
- a different order than the one in which they arrived.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>New limit-cookie-lifetime{} action to let cookies expire
- before the end of the session. Suggested by Rick Sykes in
- #1049575.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>Set the socket option SO_LINGER for the client socket.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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).</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>Allow closing curly braces as part of action values as long as
- they are escaped.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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@.</p>
- </li>
-
- <li>
- <p>Decrease the chances of parse failures after requests with
- unsupported methods were sent to the CGI interface.</p>
- </li>
- </ul>
- </li>
-
- <li>
- <p>Action file improvements:</p>
-
- <ul>
- <li>
- <p>Remove the comment that indicated that updated default.action
- versions are released on their own.</p>

- </li>
- </ul>
- </li>
-
- <li>
- <p>Filter file improvements & bug fixes:</p>
-
- <ul>
- <li>
- <p>Add a referer tagger.</p>
- </li>
-
- <li>
- <p>Reduce the likelihood that the google filter messes up
- HTML-generating JavaScript. Reported by Zeno Kugy in
- #3520260.</p>
- </li>
- </ul>
- </li>
-
- <li>
- <p>Documentation improvements:</p>
-
- <ul>
- <li>
- <p>Revised all OS X sections due to new packaging module
- (OSXPackageBuilder).</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>Update 'Signals' section, the only explicitly handled signals
- are SIGINT, SIGTERM and SIGHUP.</p>
- </li>
-
- <li>
- <p>Add Haiku to the list of operating systems on which Privoxy is
- known to run.</p>
- </li>
-
- <li>
- <p>Add DragonFly to the list of BSDs on which Privoxy is known to
- run.</p>
- </li>
-
- <li>
- <p>Removed references to redhat-specific documentation set since
- it no longer exists.</p>
- </li>
-
- <li>
- <p>Removed references to building PDFs since we no longer do
- so.</p>
- </li>
-
- <li>
- <p>Multiple listen-address directives are supported since 3.0.18,
- correct the documentation to say so.</p>
- </li>
-
- <li>
- <p>Remove bogus section about long and short being preferable to
- int.</p>
- </li>
-
- <li>
- <p>Corrected some Internet JunkBuster references to Privoxy.</p>
- </li>
-
- <li>
- <p>Removed references to www.junkbusters.com since it is no
- longer maintained. Reported by Angelina Matson.</p>
- </li>
-
- <li>
- <p>Various grammar and spelling corrections</p>
- </li>
-
- <li>
- <p>Add a client-header-tagger{} example for disabling filtering
- for range requests.</p>
- </li>
-
- <li>
- <p>Correct a URL in the "Privoxy with Tor" FAQ.</p>
- </li>
-
- <li>
- <p>Spell 'refresh-tags' correctly. Reported by Don in
- #3571927.</p>
- </li>
-
- <li>
- <p>Sort manpage options alphabetically.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>Add new contributors since 3.0.19.</p>
- </li>
- </ul>
- </li>
-
- <li>
- <p>Log message improvements:</p>
-
- <ul>
- <li>
- <p>When stopping to watch a client socket due to pipelining,
- additionally log the socket number.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
- </ul>
- </li>
-
- <li>
- <p>Code cleanups:</p>
-
- <ul>
- <li>
- <p>Remove compatibility layer for versions prior to 3.0 since it
- has been obsolete for more than 10 years now.</p>
- </li>
-
- <li>
- <p>Remove the ijb_isupper() and ijb_tolower() macros from
- parsers.c since they aren't used in this file.</p>
- </li>
-
- <li>
- <p>Removed the 'Functions declared include:' comment sections
- since they tend to be incomplete, incorrect and out of date and
- the benefit seems questionable.</p>
- </li>
-
- <li>
- <p>Various comment grammar and comprehensibility
- improvements.</p>
- </li>
-
- <li>
- <p>Remove a pointless fflush() call in chat(). Flushing all
- streams pretty much all the time for no obvious reason is
- ridiculous.</p>
- </li>
-
- <li>
- <p>Relocate ijb_isupper()'s definition to project.h and get the
- ijb_tolower() definition from there, too.</p>
- </li>
-
- <li>
- <p>Relocate ijb_isdigit()'s definition to project.h.</p>
- </li>
-
- <li>
- <p>Rename ijb_foo macros to privoxy_foo.</p>
- </li>
-
- <li>
- <p>Add malloc_or_die() which will allow to simplify code paths
- where malloc() failures don't need to be handled gracefully.</p>
- </li>
-
- <li>
- <p>Add strdup_or_die() which will allow to simplify code paths
- where strdup() failures don't need to be handled gracefully.</p>
- </li>
-
- <li>
- <p>Replace strdup() calls with strdup_or_die() calls where it's
- safe and simplifies the code.</p>
- </li>
-
- <li>
- <p>Fix white-space around parentheses.</p>
- </li>
-
- <li>
- <p>Add missing white-space behind if's and the following
- parentheses.</p>
- </li>
-
- <li>
- <p>Unwrap a memcpy() call in resolve_hostname_to_ip().</p>
- </li>
-
- <li>
- <p>Declare pcrs_get_delimiter()'s delimiters[] static const.</p>
- </li>
-
- <li>
- <p>Various optimisations to remove dead code and merge
- inefficient code structures for improved clarity, performance or
- code compactness.</p>
- </li>
-
- <li>
- <p>Various data type corrections.</p>
- </li>
-
- <li>
- <p>Change visibility of several code segments when compiling
- without FEATURE_CONNECTION_KEEP_ALIVE enabled for clarity.</p>
- </li>
-
- <li>
- <p>In pcrs_get_delimiter(), do not use delimiters ouside the
- ASCII range. Fixes a clang complaint.</p>
- </li>
-
- <li>
- <p>Fix an error message in get_last_url() nobody is supposed to
- see. Reported by Matthew Fischer in #3507301.</p>
- </li>
-
- <li>
- <p>Fix a typo in the no-zlib-support complaint. Patch submitted
- by Matthew Fischer in #3507304.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>Use an enum for the type of the action value.</p>
- </li>
-
- <li>
- <p>Rename action_name's member takes_value to value_type as it
- isn't used as boolean.</p>
- </li>
-
- <li>
- <p>Turn family mismatches in match_sockaddr() into fatal
- errors.</p>
- </li>
-
- <li>
- <p>Let enlist_unique_header() verify that the caller didn't pass
- a header containing either \r or \n.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>Use privoxy_tolower() instead of vanilla tolower() with manual
- casting of the argument.</p>
- </li>
-
- <li>
- <p>Catch ssplit() failures in parse_cgi_parameters().</p>
- </li>
- </ul>
- </li>
-
- <li>
- <p>Privoxy-Regression-Test:</p>
-
- <ul>
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>Log to STDOUT instead of STDERR.</p>
- </li>
-
- <li>
- <p>Include the Privoxy version in the output.</p>
- </li>
-
- <li>
- <p>Various grammar and spelling corrections in documentation and
- code.</p>
- </li>
-
- <li>
- <p>Additional tests for range requests with filtering
- enabled.</p>
- </li>
-
- <li>
- <p>Tests with mostly invalid range request.</p>
- </li>
-
- <li>
- <p>Add a couple of hide-if-modified-since{} tests with different
- date formats.</p>
- </li>
-
- <li>
- <p>Cleaned up the format of the regression-tests.action file to
- match the format of default.action.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
- </ul>
- </li>
-
- <li>
- <p>Privoxy-Log-Parser:</p>
-
- <ul>
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>The distribution of client requests per connection is included
- in the --statistic output.</p>
- </li>
-
- <li>
- <p>The --accept-unknown-messages option has been removed and the
- behavior is now the default.</p>
- </li>
-
- <li>
- <p>Accept and (mostly) highlight new log messages introduced with
- Privoxy 3.0.20.</p>
- </li>
- </ul>
- </li>
-
- <li>
- <p>uagen:</p>
-
- <ul>
- <li>
- <p>Bump generated Firefox version to 17.</p>
- </li>
- </ul>
- </li>
-
- <li>
- <p>GNUmakefile improvements:</p>
-
- <ul>
- <li>
- <p>The dok-tidy target no longer taints documents with a
- tidy-mark</p>
- </li>
-
- <li>
- <p>Change RA_MODE from 0664 to 0644. Suggested by Markus Dittrich
- in #3505445.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>Leave it up to the user whether or not smart tags are
- inserted.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>Ditch a pointless '-r' passed to rm to delete files.</p>
- </li>
-
- <li>
- <p>The config-file target now requires less manual intervention
- and updates the original config.</p>
- </li>
-

- <p>configure improvements:</p>
-
- <ul>
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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 ***</p>
- </li>
- </ul>
- </li>
-
- <li>
- <p>Bug fixes:</p>
-
- <ul>
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
- </ul>
- </li>
-
- <li>
- <p>General improvements:</p>
-
- <ul>
- <li>
- <p>Fix an off-by-one in an error message about connect
- failures.</p>
- </li>
-
- <li>
- <p>Use a GNUMakefile variable for the webserver root directory
- and update the path. Sourceforge changed it which broke various
- web-related targets.</p>
- </li>
-
- <li>
- <p>Update the CODE_STATUS description.</p>

- to Upgraders</a></h2>
-
- <p>A quick list of things to be aware of before upgrading from earlier
- versions of <span class="APPLICATION">Privoxy</span>:</p>
-
- <ul>
- <li>
- <p>The recommended way to upgrade <span class=
- "APPLICATION">Privoxy</span> is to backup your old configuration
- files, install the new ones, verify that <span class=
- "APPLICATION">Privoxy</span> is working correctly and finally merge
- back your changes using <span class="APPLICATION">diff</span> and
- maybe <span class="APPLICATION">patch</span>.</p>
-
- <p>There are a number of new features in each <span class=
- "APPLICATION">Privoxy</span> release and most of them have to be
- explicitly enabled in the configuration files. Old configuration
- files obviously don't do that and due to syntax changes using old
- configuration files with a new <span class=
- "APPLICATION">Privoxy</span> isn't always possible anyway.</p>
- </li>
-
- <li>
- <p>Note that some installers remove earlier versions completely,
- including configuration files, therefore you should really save any
- important configuration files!</p>
- </li>
-
- <li>
- <p>On the other hand, other installers don't overwrite existing
- configuration files, thinking you will want to do that
- yourself.</p>
- </li>
-
- <li>
- <p><tt class="FILENAME">standard.action</tt> has been merged into
- the <tt class="FILENAME">default.action</tt> file.</p>
- </li>
-
- <li>
- <p>In the default configuration only fatal errors are logged now.
- You can change that in the <a href="config.html#DEBUG">debug
- section</a> of the configuration file. You may also want to enable
- more verbose logging until you verified that the new <span class=
- "APPLICATION">Privoxy</span> version is working as expected.</p>
- </li>
-
- <li>
- <p>Three other config file settings are now off by default:
- <a href="config.html#ENABLE-REMOTE-TOGGLE">enable-remote-toggle</a>,
- <a href=
- "config.html#ENABLE-REMOTE-HTTP-TOGGLE">enable-remote-http-toggle</a>,
- and <a href=
- "config.html#ENABLE-EDIT-ACTIONS">enable-edit-actions</a>. If you
- use or want these, you will need to explicitly enable them, and be
- aware of the security issues involved.</p>
