<listitem>
<para>
- 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.
+ 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.

<para>
- 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.
+ Add a listen-backlog directive which specifies the backlog
+ value passed to listen().
+ Sponsored by: Robert Klemme
</para>
</listitem>
<listitem>
<para>
- 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.
+ 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.

- The default-server-timeout and socket-timeout directives accept 0 as

+ 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.

- New directive tolerate-pipelining to allow client-side pipelining.
- If enabled (3.0.20 beta enables it by default), Privoxy will keep

- request has been served.
+ Free csp resources in the thread that belongs to the csp instead
+ of the main thread which has enough on its plate already.

<para>
- 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.
+ 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.

<para>
- New limit-cookie-lifetime{} action to let cookies expire before the end
- of the session. Suggested by Rick Sykes in #1049575.
+ Explicitly taint the server socket in case of CONNECT requests.
+ This doesn't fix any known problems, but makes
+ some log messages less confusing.
</para>
</listitem>
<listitem>
<para>
- 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.
+ Let write_pid_file() terminate if the pid file can't be opened.
+ Logging the issue at info level is unlikely to help.
</para>
</listitem>
<listitem>
<para>
- 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.
+ 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
</para>
</listitem>
<listitem>
<para>
- 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.
+ 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
</para>
</listitem>
<listitem>
<para>
- 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.
+ 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
</para>
</listitem>
<listitem>
<para>
- Stop considering client sockets tainted after receiving a request with body.
- It hasn't been necessary for a while now and unnecessarily causes test
- failures when using curl's test suite.
+ 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.
</para>
</listitem>
<listitem>
<para>
- 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.
+ 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.
</para>
</listitem>
<listitem>
<para>
- 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.
+ 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.
</para>
</listitem>
<listitem>
<para>
- Set the socket option SO_LINGER for the client socket.
+ 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.
</para>
</listitem>
<listitem>
<para>
- 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.
+ 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.
</para>
</listitem>
<listitem>
<para>
- 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).
+ 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.
</para>
</listitem>

<para>
- 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.
+ 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.
</para>

<para>
- 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

</para>
</listitem>
<listitem>
<para>
- Allow closing curly braces as part of action values as long as they are
- escaped.
+ 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.

<para>
- 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.
+ 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.
