+ <h1 class="SECT1"><a name="WHATSNEW" id="WHATSNEW">3. What's New in this Release</a></h1>
+ <p><span class="APPLICATION">Privoxy 3.0.27</span> stable scales better in multi-user environments and brings a
+ couple of tuning directives. <span class="APPLICATION">Privoxy 3.0.28</span> stable fixes two regressions
+ introduced in 3.0.27.</p>
+ <p>Changes in <span class="APPLICATION">Privoxy 3.0.28</span> stable:</p>
<ul>
<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>
-
+ <p>Bug fixes for regressions in 3.0.27:</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>
+ <p>Fixed misplaced parentheses. Reported by David Binderman.</p>
</li>
-
<li>
- <p>Update the CODE_STATUS description.</p>
+ <p>Changed two regression tests to depend on config directive enable-remote-toggle instead of
+ FEATURE_TOGGLE.</p>
</li>
</ul>
</li>
</ul>
-
- <p>The following changes were made between 3.0.17 and 3.0.18:</p>
-
+ <p>Changes in <span class="APPLICATION">Privoxy 3.0.27</span> stable:</p>
<ul>
- <li>
- <p>Bug fixes:</p>
-
- <ul>
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>If forwarded-connect-retries is set, only retry if Privoxy is
- actually forwarding the request. Previously direct connections
- would be retried as well.</p>
- </li>
-
- <li>
- <p>Fixed a small memory leak when retrying connections with IPv6
- support enabled.</p>
- </li>
-
- <li>
- <p>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).</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>In html_code_map[], use a numeric character reference instead
- of ' which wasn't standardized before XHTML 1.0.</p>
- </li>
-
- <li>
- <p>Fix an invalid free when compiled with
- FEATURE_GRACEFUL_TERMINATION and shut down through
- http://config.privoxy.org/die</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
- </ul>
- </li>
-
<li>
<p>General improvements:</p>
-
<ul>
<li>
- <p>Privoxy can (re)compress buffered content before delivering it
- to the client. Disabled by default as most users wouldn't benefit
- from it.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>Allow to bind to multiple separate addresses. Patch set
- submitted by Petr Pisar in #3354485.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>When compiled without FEATURE_FAST_REDIRECTS, do not silently
- ignore +fast-redirect{} directives</p>
- </li>
-
- <li>
- <p>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</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>In case of SOCKS5 failures, dump the socks response in the log
- message.</p>
- </li>
-
- <li>
- <p>Simplify the signal setup in main().</p>
- </li>
-
- <li>
- <p>Streamline socks5_connect() slightly.</p>
+ <p>Add a receive-buffer-size directive which can be used to set the size of the previously statically
+ allocated buffer in handle_established_connection(). Increasing the buffer size increases Privoxy's memory
+ usage but can lower the number of context switches and thereby reduce the CPU usage and potentially
+ increase the throughput. This is mostly relevant for fast network connections and large downloads that
+ don't require filtering. Sponsored by: Robert Klemme</p>
</li>
-
<li>
- <p>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.</p>
+ <p>Add a listen-backlog directive which specifies the backlog value passed to listen(). Sponsored by:
+ Robert Klemme</p>
</li>
-
<li>
- <p>In chat(), do not bother to generate a client request in case
- of direct CONNECT requests. It will not be used anyway.</p>
+ <p>Add an enable-accept-filter directive which allows to toggle accept filter support at run time when
+ compiled with FEATURE_ACCEPT_FILTER support. It makes testing more convenient and now that it's optional we
+ can emit an error message if enabling the accept filter fails. Sponsored by: Robert Klemme</p>
</li>
-
<li>
- <p>Reduce server_last_modified()'s stack size.</p>
+ <p>Add a delay-response{} action. This is useful to tar pit JavaScript requests that are endlessly retried
+ in case of blocks. It can also be used to simulate a slow Internet connection. Sponsored by: Robert
+ Klemme</p>
</li>
-
<li>
- <p>Shorten get_http_time() by using strftime().</p>
+ <p>Add a 'trusted-cgi-referrer' directive. It allows to configure another page or site that can be used to
+ reach sensitive CGI resources. Sponsored by: Robert Klemme</p>
</li>
-
<li>
- <p>Constify the known_http_methods pointers in
- unknown_method().</p>
+ <p>Add a --fuzz mode which exposes Privoxy internals to input from files or stdout. Mainly tested with
+ American Fuzzy Lop. For details see: https://www.fabiankeil.de/talks/fuzzing-on-freebsd/ This work was
+ partially funded with donations and done as part of the Privoxy month in 2015.</p>
</li>
-
<li>
- <p>Constify the time_formats pointers in parse_header_time().</p>
+ <p>Consistently use the U(ngreedy) flag in the 'img-reorder' filter.</p>
</li>
-
<li>
- <p>Constify the formerly_valid_actions pointers in
- action_used_to_be_valid().</p>
+ <p>listen_loop(): Reuse a single thread attribute object The object doesn't change and creating a new one
+ for every thread is a waste of (CPU) time. Sponsored by: Robert Klemme</p>
</li>
-
<li>
- <p>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.</p>
+ <p>Free csp resources in the thread that belongs to the csp instead of the main thread which has enough on
+ its plate already. Sponsored by: Robert Klemme</p>
</li>
-
<li>
- <p>Deduplicate the INADDR_NONE definition for Solaris by moving
- it to jbsockets.h</p>
+ <p>Improve 'socket timeout reached' message. Log the timeout that was triggered and downgrade the log level
+ to LOG_LEVEL_CONNECT to reduce the log noise with common debug settings. The timeout isn't necessary the
+ result of an error and usually merely indicates that Privoxy's socket timeout is lower than the relevant
+ timeouts used by client and server. Sponsored by: Robert Klemme</p>
</li>
-
<li>
- <p>In block_url(), ditch the obsolete workaround for ancient
- Netscape versions that supposedly couldn't properly deal with
- status code 403.</p>
+ <p>Explicitly taint the server socket in case of CONNECT requests. This doesn't fix any known problems, but
+ makes some log messages less confusing.</p>
</li>
-
<li>
- <p>Remove a useless NULL pointer check in load_trustfile().</p>
+ <p>Let write_pid_file() terminate if the pid file can't be opened. Logging the issue at info level is
+ unlikely to help.</p>
</li>
-
<li>
- <p>Remove two useless NULL pointer checks in
- load_one_re_filterfile().</p>
+ <p>log_error(): Reduce the mutex-protected area by not using a heap-allocated buffer that is shared between
+ all threads. This increases performance and reduces the latency with verbose debug settings and multiple
+ concurrent connections. Sponsored by: Robert Klemme</p>
</li>
-
<li>
- <p>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.</p>
+ <p>Let zalloc() use calloc() if it's available. In some situations using calloc() can be faster than
+ malloc() + memset() and it should never be slower. In the real world the impact of this change is not
+ expected to be noticeable. Sponsored by: Robert Klemme</p>
</li>
-
<li>
- <p>Fix various typos. Fixes taken from Debian's 29_typos.dpatch
- by Roland Rosenfeld.</p>
+ <p>Never use select() when poll() is available. On most platforms select() is limited by FD_SETSIZE while
+ poll() is not. This was a scaling issue for multi-user setups. Using poll() has no downside other than the
+ usual risk that code modifications may introduce new bugs that have yet to be found and fixed. At least in
+ theory this commit could also reduce the latency when there are lots of connections and select() would use
+ "bit fields in arrays of integers" to store file descriptors. Another side effect is that Privoxy no longer
+ has to stop monitoring the client sockets when pipelined requests are waiting but can't be read yet. This
+ code keeps the select()-based code behind ifdefs for now but hopefully it can be removed soonish to make
+ the code more readable. Sponsored by: Robert Klemme</p>
</li>
-
<li>
- <p>Add a dok-tidy GNUMakefile target to clean up the messy HTML
- generated by the other dok targets.</p>
+ <p>Add a 'reproducible-tarball-dist' target. It's currently separate from the "tarball-dist" target because
+ it requires a tar implementation with mtree spec support. It's far from being perfect and does not enforce
+ a reproducible mode, but it's better than nothing.</p>
</li>
-
<li>
- <p>GNUisms in the GNUMakefile have been removed.</p>
+ <p>Use arc4random() if it's available. While Privoxy doesn't need high quality pseudo-random numbers
+ there's no reason not to use them when we can and this silences a warning emitted by code checkers that
+ can't tell whether or not the quality matters.</p>
</li>
-
<li>
- <p>Change the HTTP version in static responses to 1.1</p>
+ <p>Show the FEATURE_EXTERNAL_FILTERS status on the status page. Better late than never. Previously a couple
+ of tests weren't executed as Privoxy-Regression-Test couldn't detect that the FEATURE_EXTERNAL_FILTERS
+ dependency was satisfied.</p>
</li>
-
<li>
- <p>Synced config.sub and config.guess with upstream
- 2011-11-11/386c7218162c145f5f9e1ff7f558a3fbb66c37c5.</p>
+ <p>Ditch FEATURE_IMAGE_DETECT_MSIE. It's an obsolete workaround we inherited from Junkbuster and was
+ already disabled by default. Users that feel the urge to work around issues with image requests coming from
+ an Internet Explorer version from more than 15 years ago can still do this using tags.</p>
</li>
-
<li>
- <p>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.</p>
+ <p>Consistently use strdup_or_die() instead of strdup() in cases where allocation failures aren't expected.
+ Using strdup_or_die() allows to remove a couple of explicit error checks which slightly reduces the size of
+ the binary.</p>
</li>
-
<li>
- <p>Terminate HTML lines in static error messages with \n instead
- of \r\n.</p>
+ <p>Insert a refresh tag into the /client-tags CGI page when serving it while a client-specific tag is
+ temporarily enabled. This makes it less likely that the user ends up looking at tag state that is out of
+ date.</p>
</li>
-
<li>
- <p>Simplify cgi_error_unknown() a bit.</p>
+ <p>Use absolute URLs in the client-tag forms. It's more consistent with the rest of the CGI page URLs and
+ makes it more convenient to copy the forms to external pages.</p>
</li>
-
<li>
- <p>In LogPutString(), don't bother looking at pszText when not
- actually logging anything.</p>
+ <p>cgi_error_disabled(): Use status code 403 and an appropriate response line</p>
</li>
-
<li>
- <p>Change ssplit()'s fourth parameter from int to size_t. Fixes a
- clang complaint.</p>
+ <p>Use a dedicated CGI handler to deal with tag-toggle requests As a result the /client-tags page is now
+ safe to reach without trusted Referer header which makes bookmarking or linking to it more convenient.
+ Finally, refreshing the /client-tags page to show the current state can no longer unintentionally repeat
+ the previous toggle request.</p>
</li>
-
<li>
- <p>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.</p>
+ <p>Don't add a "Connection" header for CONNECT requests. Explicitly sending "Connection: close" is not
+ necessary and apparently it causes problems with some forwarding proxies that will close the connection
+ prematurely. Reported by Marc Thomas.</p>
</li>
-
<li>
- <p>In rfc2553_connect_to(), start setting cgi->error_message
- on error.</p>
+ <p>Fix compiler warnings.</p>
</li>
-
- <li>
- <p>Change the expected status code returned for http://p.p/die
- depending on whether or not FEATURE_GRACEFUL_TERMINATION is
- available.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>Add a proper CGI message for cgi_die().</p>
- </li>
-
- <li>
- <p>Don't enforce a logical line length limit in
- read_config_line().</p>
- </li>
-
- <li>
- <p>Slightly refactor server_last_modified() to remove useless
- gmtime*() calls.</p>
- </li>
-
- <li>
- <p>In get_content_type(), also recognize '.jpeg' as JPEG
- extension.</p>
- </li>
-
- <li>
- <p>Add '.png' to the list of recognized file extensions in
- get_content_type().</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
+ </ul>
+ </li>
+ <li>
+ <p>Bug fixes:</p>
+ <ul>
<li>
- <p>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.</p>
+ <p>rfc2553_connect_to(): Properly detect and log when poll() reached the time out. Previously this was
+ logged as: Could not connect to [...]: No error: 0. which isn't very helpful. Sponsored by: Robert
+ Klemme</p>
</li>
-
<li>
- <p>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.</p>
+ <p>add_tag_for_client(): Set time_to_live properly. Previously the time_to_live was always set for the
+ first tag. Attempts to temporarily enable a tag would result in enabling it permanently unless no tag was
+ enabled already.</p>
</li>
-
<li>
- <p>The socket timeout is used for SOCKS negotiations as well
- which previously couldn't timeout.</p>
+ <p>Revert r1.165 which didn't perform as advertised. While the idea was to use "https:// when creating
+ links for the user manual on the website", the actual effect was to use "https://" when Privoxy was
+ supposed to serve the user manual itself. Reported by Yossi Zahn on Privoxy-devel@.</p>
</li>
-
<li>
- <p>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.</p>
+ <p>socks5_connect(): Fail in case of unsupported address types. Previously they would not be detected right
+ away and Privoxy would fail later on with an error message that didn't make it obvious that the problem was
+ socks-related. So far, no such problems have actually been reported.</p>
</li>
-
<li>
- <p>Treat all Content-Type header values containing the pattern
- 'script' as a sign of text. Reported by pribog in #3134970.</p>
+ <p>socks5_connect(): Properly deal with socks replies that contain IPv6 addresses. Previously parts of the
+ reply were left unread and later on treated as invalid HTTP response data. Fixes #904 reported by Danny
+ Goossen who also provided the initial version of this patch.</p>
</li>
</ul>
</li>
-
<li>
<p>Action file improvements:</p>
-
<ul>
<li>
- <p>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.</p>
- </li>
-
- <li>
- <p>Remove -prevent-compression from the fragile alias. It's no
- longer used anywhere by default and isn't known to break stuff

+ <p>Unblock 'msdn.microsoft.com/'. It (presumably) isn't used to serve the kind of ads Privoxy should block

<li>
- <p>Add a (disabled) section to block various Facebook tracking
- URLs. Reported by Dan Stahlke in #3421764.</p>
+ <p>Disable gif deanimation for requests tagged with CSS-REQUEST. The action will ignore content that isn't
+ considered text anyway and explicitly disabling it makes this more obvious if "action" debugging (debug
+ 65536) is enabled while "gif deanimation" debugging (debug 256) isn't.</p>

<li>
- <p>Add a (disabled) section to rewrite and redirect
- click-tracking URLs used on news.google.com. Reported by Dan
- Stahlke in #3421755.</p>
+ <p>Explicitly disable HTML filters for requests with CSS-REQUEST tag. The filters are unlikely to break CSS
+ files but executing them without (intentionally) getting any hits is a waste of cpu time and makes the log
+ more noisy when running with "debug 64".</p>

- </li>
-
- <li>
- <p>Let the msn filter hide overlay ads for Facebook 'likes' in

</li>
-
<li>
- <p>Let the js-events filter additionally disarm setInterval().
- Suggested by dg1727 in #3423775.</p>
+ <p>Bump version as the behaviour (slightly) changed.</p>

- </ul>
- </li>
-
- <li>
- <p>Documentation improvements:</p>
-
- <ul>
- <li>
- <p>Clarify the effect of compiling Privoxy with zlib support.
- Suggested by dg1727 in #3423782.</p>
- </li>
-
<li>
- <p>Point out that the SourceForge messaging system works like a
- black hole and should thus not be used to contact individual
- developers.</p>
+ <p>Count connection failures as well in statistics mode. Sponsored by: Robert Klemme</p>
</li>
-
<li>

- explicitly configuring an IP addresses as listen address.</p>
+ <p>Count connection timeouts as well in statistics mode. Sponsored by: Robert Klemme</p>
</li>
-
<li>
- <p>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.</p>
+ <p>Fix an 'uninitialized value' warning when generating statistics for a log file without response headers.
+ While privoxy-log-parser was supposed to detect this already, the check was flawed and the message the user
+ didn't see was somewhat confusing anyway. Now the message is less confusing, more helpful and actually
+ printed. Reported by: Robert Klemme</p>

-
<li>
- <p>Log message improvements:</p>
-
+ <p>Documentation improvements:</p>
<ul>
<li>
- <p>If only the server connection is kept alive, do not pretend to
- wait for a new client request.</p>
- </li>
-
- <li>
- <p>Remove a superfluous log message in forget_connection().</p>
- </li>
-
- <li>
- <p>In chat(), properly report missing server responses as such
- instead of calling them empty.</p>
- </li>
-
- <li>
- <p>In forwarded_connect(), fix a log message nobody should ever
- see.</p>
- </li>
-
- <li>
- <p>Fix a log message in socks5_connect(), a failed write
- operation was logged as failed read operation.</p>
- </li>
-
- <li>
- <p>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.</p>
- </li>
-
- <li>
- <p>Do not claim to listen on a socket until Privoxy actually
- does. Patch submitted by Petr Pisar #3354485</p>
- </li>
-
- <li>
- <p>Prevent a duplicated LOG_LEVEL_CLF message when sending out
- the "no-server-data" response.</p>
- </li>
-
- <li>
- <p>Also log the client socket when dropping a connection.</p>
- </li>
-
- <li>
- <p>Include the destination host in the 'Request ... marked for
- blocking. limit-connect{...} doesn't allow CONNECT ...' message
- Patch submitted by Saperski in #3296250.</p>
- </li>
-
- <li>
- <p>Prevent a duplicated log message if none of the resolved IP
- addresses were reachable.</p>
- </li>
-
- <li>
- <p>In connect_to(), do not pretend to retry if
- forwarded-connect-retries is zero or unset.</p>
- </li>
-
- <li>
- <p>When a specified user or group can't be found, put the name in
- single-quotes when logging it.</p>
+ <p>Refer to the git sources instead of CVS.</p>
</li>
-
<li>
- <p>In rfc2553_connect_to(), explain getnameinfo() errors
- better.</p>
+ <p>Use GNU/Linux when referring to the OS instead of the kernel.</p>
</li>
-
<li>
- <p>Remove a useless log message in chat().</p>
+ <p>Add FAQ entry for what to do if editing the config file is access denied.</p>
</li>
-
<li>
- <p>When retrying to connect, also log the maximum number of
- connection attempts.</p>
+ <p>Add brief HTTP/2 FAQ.</p>
</li>
-
<li>
- <p>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.</p>
+ <p>Add a small fuzzing section to the developer documentation.</p>
</li>
-
<li>
- <p>In a fatal error message in load_one_actions_file(), cover
- both URL and TAG patterns.</p>
+ <p>Add a client-header-tagger{client-ip-address} example.</p>
</li>
-
<li>
- <p>In pcrs_strerror(), properly report unknown positive error
- code values as such. Previously they were handled like 0 (no
- error).</p>
+ <p>Stop suggesting that Privoxy is an anonymizing proxy. The term could lead to Privoxy users
+ overestimating what it can do on its own (without Tor).</p>
</li>
-
<li>
- <p>In compile_dynamic_pcrs_job_list(), also log the actual error
- code as pcrs_strerror() doesn't handle all errors reported by
- pcre.</p>
+ <p>Make it more obvious that SPI accepts Paypal, too. Currently most donations are made through the Paypal
+ account managed by Zwiebelfreunde e.V. and a more even distribution would be useful.</p>
</li>
-
<li>
- <p>Don't bother trying to continue chatting if the client didn't
- ask for it. Reduces log noise a bit.</p>
+ <p>Suggest to log applying actions as well when reproducing problems.</p>
</li>
-
<li>
- <p>Make two fatal error message in load_one_actions_file() more
- descriptive.</p>
+ <p>Explicitly mention that Privoxy binaries are built by individuals on their own systems. Buyer
+ beware!</p>
</li>
-
<li>
- <p>In cgi_send_user_manual(), log when rejecting a file name due
- to '/' or '..'.</p>
+ <p>Mention the release feed on the homepage.</p>
</li>
-
<li>
- <p>In load_file(), log a message if opening a file failed. The
- CGI error message alone isn't too helpful.</p>
- </li>
-
- <li>
- <p>In connection_destination_matches(), improve two log messages
- to help understand why the destinations don't match.</p>
- </li>
-
- <li>
- <p>Rephrase a log message in serve(). Client request arrival
- should be differentiated from closed client connections now.</p>
- </li>
-
- <li>
- <p>In serve(), log if a client connection isn't reused due to a
- configuration file change.</p>
- </li>
-
- <li>
- <p>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.</p>
+ <p>Remove a mysterious comment with a GNU FDL link as it isn't useful and could confuse license scanners.
+ In May 2002 it was briefly claimed that "this document" was covered by the GNU FDL. The commit message
+ (r1.5) doesn't explain the motivation or whether all copyright holders were actually asked and agreed to
+ the declared license change. It's thus hard to tell whether or not the license change was legit, but
+ luckily two days later the "doc license" was "put" "back to GPL" anyway (r1.6). At the same time the
+ offending comment with a link to the FDL (not the GPL) was added for no obvious reason. Now it's gone
+ again.</p>

- <li>
- <p>Do not check for the existence of strerror() and memmove()
- twice</p>
- </li>
-
- <li>
- <p>Remove a useless test for setpgrp(2). Privoxy doesn't need it
- and it can cause problems when cross-compiling.</p>
- </li>
-
- <li>
- <p>Rename the --disable-acl-files switch to
- --disable-acl-support. Since about 2001, ACL directives are

+ code 403 (instead of 200).</p>
</li>
-
<li>
- <p>Update the URL of the 'Removing outdated PCRE version after

- <p>In the --help output, include a list of supported tests and
- their default levels.</p>
- </li>
-
- <li>
- <p>Adjust the tests to properly deal with FEATURE_TOGGLE being
- disabled.</p>
+ <p>Move the site-specific documentation block before the generic one. While most Privoxy installations
+ don't have a site-specific documentation block, in cases were it exists it's likely to be more relevant
+ than the generic one. Showing it first makes it less likely that users stop reading before they reach it,

</li>
-
<li>
- <p>Only randomize the release date if the new
