<para>
<itemizedlist>
- <listitem>
- <para>
- 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 or the
- request timed out. Reported by "Karsten" in #3028326.
- </para>
- </listitem>
- <listitem>
- <para>
- Responses with status code 204 weren't properly detected as body-less
- like RFC2616 mandates. Like the previous bug, this caused Privoxy to
- wait for the end of the content until the server closed the connection
- or the request timed out. Fixes #3022042 and #3025553, reported by a
- user with no visible name. Most likely also fixes a bunch of other
- AJAX-related problem reports that got closed in the past due to
- insufficient information and lack of feedback.
- </para>
- </listitem>
- <listitem>
- <para>
- Fixed an ACL bug that made it impossible to build a blacklist.
- Usually the ACL directives are used in a whitelist, which worked
- as expected, but blacklisting is still useful for public proxies
- where one only needs to deny known abusers access.
- </para>
- </listitem>
- <listitem>
- <para>
- Added LOG_LEVEL_RECEIVED to log the not-yet-parsed data read from the
- network. This should make debugging various parsing issues a lot easier.
- </para>

- <para>
- The IPv6 code is enabled by default on Windows versions that support it.
- Patch submitted by oCameLo in #2942729.
- </para>
- </listitem>
- <listitem>
+ <listitem>
<para>
- In mingw32 versions, the user.filter file is reachable through the
- GUI, just like default.filter is. Feature request 3040263.
+ Bug fixes:
+ <itemizedlist>
+ <listitem>
+ <para>
+ Fix a logic bug that could cause Privoxy to reuse a tainted
+ server socket.
+ It could happen for server sockets that got tainted by a
+ server-header-tagger-induced block, in which case Privoxy
+ doesn't necessarily read the whole server response.
+ 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.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ 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 like curl which terminates the client connection
+ after detecting that the whole body has been received it doesn't
+ really matter, but with clients like FreeBSD's fetch the client
+ connection would be kept open until it timed out.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ 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.
+ I've only seen it 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.
+ </para>

<para>
- Added the configure option --enable-large-file-support to set a few
- defines that are required by platforms like GNU/Linux to support files
- larger then 2GB. Mainly interesting for users without proper logfile
- management.
+ General improvements:
+ <itemizedlist>
+ <listitem>
+ <para>
+ Privoxy can (re)compress buffered content before delivering
+ it to the client. Disabled by default as most users wouldn't
+ benefit from it.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ 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 of by additionally
+ using a +redirect{} pcrs command.
+ Initial patch submitted by Jamie Zawinski in #3429848.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Properly deal with FEATURE_TOGGLE being disabled
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ 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 actual problems I'm aware of.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ When compiled without FEATURE_FAST_REDIRECTS, do not silently
+ ignore +fast-redirect{} directives
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ 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
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ 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.
+ </para>

+ <para>
+ Allow to bind to multiple separate addresses.
+ Patch set submitted by Petr Pisar in #3354485.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Set socket_error to errno if connecting fails in rfc2553_connect_to()
+ Previously rejected direct connections could be incorrectly reported as DNS issues.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ 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.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Disable filters if SDCH compression is used unless filtering is forced.
+ If SDCH was combined with a supported compression algorithm,
+ we'd previously try to decompress it, when successful apply
+ the enabled filters and ditch the Content-Encoding header
+ even though the SDCH compression wasn't removed.
+ Reported by zebul666 in #3225863.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ 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.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ 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.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ If forwarded-connect-retries is set, only retry if the we are actually
+ forwarding the request. Previously direct connections would be retried
+ as well.
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ Fixed a small memory leak when retrying connection
+ </para>
+ </listitem>
+ <listitem>
+ <para>
+ 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).
+ </para>
+ </listitem>
+ </itemizedlist>
</para>
</listitem>
<listitem>
<para>
- Logging with "debug 16" no longer stops at the first nul byte which is
- pretty useless. Non-printable characters are replaced with their hex value
- so the result can't span multiple lines making parsing them harder then
- necessary.
+ Action file improvements:
+ <itemizedlist>
+ <listitem>
+ <para>
+ 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.
+ </para>
+ </listitem>

- Fixed incorrect regression test markup which caused a test in

- Fix a bug in handle_loglevel_header() where a 'scan: ' got lost.
