+
+ <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>
+
+ <li>

+ 'optimized-by.rubiconproject.com/'</p>

+ Submitted by Adam Piggott in #3596089.</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>

+ 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>
- 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.
- </p>
- </li>
- <li>
- <p>
- 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.
- </p>
- </li>
- <li>
- <p>
- 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.
- </p>
- </li>
- <li>
- <p>
- 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.
- </p>
- </li>
- <li>
- <p>
- The IPv6 code is enabled by default on Windows versions that
- support it. Patch submitted by oCameLo in #2942729.
- </p>
- </li>
- <li>
- <p>
- In mingw32 versions, the user.filter file is reachable through
- the GUI, just like default.filter is. Feature request 3040263.
- </p>
- </li>
- <li>
- <p>
- 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.
- </p>
- </li>
- <li>
- <p>
- 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.
- </p>
- </li>
- <li>
- <p>
- Privoxy logs when reading an action, filter or trust file.
- </p>
- </li>
- <li>
- <p>
- Fixed incorrect regression test markup which caused a test in
- 3.0.16 to fail while Privoxy itself was working correctly. While
- Privoxy accepts hide-referer, too, the action name is actually
- hide-referrer which is also the name used one the final results
- page, where the test expected the alias.
- </p>
- </li>
- <li>
- <p>
- CGI interface improvements:
- </p>
- <ul>
- <li>
- <p>
- In finish_http_response(), continue to add the 'Connection:
- close' header if the client connection will not be kept
- alive. Anonymously pointed out in #2987454.
- </p>
- </li>
- <li>
- <p>
- Apostrophes in block messages no longer cause parse errors
- when the blocked page is viewed with JavaScript enabled.
- Reported by dg1727 in #3062296.
- </p>
- </li>
- <li>
- <p>
- Fix a bunch of anchors that used underscores instead of
- dashes.
- </p>
- </li>
- <li>
- <p>
- Allow to keep the client connection alive after crunching the
- previous request. Already opened server connections can be
- kept alive, too.
- </p>
- </li>
- <li>
- <p>
- 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.
- </p>
- </li>
- <li>
- <p>
- Show the 404 CGI page if cgi_send_user_manual() is called
- while local user manual delivery is disabled.
- </p>
- </li>
- </ul>
+ <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>
- Action file improvements:
- </p>
- <ul>
- <li>
- <p>
- Enable user.filter by default. Suggested by David White in
- #3001830.
- </p>
- </li>
- <li>
- <p>
- Block .sitestat.com/. Reported by johnd16 in #3002725.
- </p>
- </li>
- <li>
- <p>
- Block .atemda.com/. Reported by johnd16 in #3002723.
- </p>
- </li>
- <li>
- <p>
- Block js.adlink.net/. Reported by johnd16 in #3002720.
- </p>
- </li>
- <li>
- <p>
- Block .analytics.yahoo.com/. Reported by johnd16 in #3002713.
- </p>
- </li>
- <li>
- <p>
- Block sb.scorecardresearch.com, too. Reported by dg1727 in
- #2992652.
- </p>
- </li>
- <li>
- <p>
- Fix problems noticed on Yahoo mail and news pages.
- </p>
- </li>
- <li>
- <p>
- Remove the too broad yahoo section, only keeping the
- fast-redirects exception as discussed on ijbswa-devel@.
- </p>
- </li>
- <li>
- <p>
- Don't block adesklets.sourceforge.net. Reported in #2974204.
- </p>
- </li>
- <li>
- <p>
- Block chartbeat ping tracking. Reported in #2975895.
- </p>
- </li>
- <li>
- <p>
- Tag CSS and image requests with cautious and medium settings,
- too.
- </p>
- </li>
- <li>
- <p>
- Don't handle view.atdmt.com as image. It's used for
- click-throughs so users should be able to "go there anyway".
- Reported by Adam Piggott in #2975927.
- </p>
- </li>
- <li>
- <p>
- Also let the refresh-tags filter remove invalid refresh tags
- where the 'url=' part is missing. Anonymously reported in
- #2986382. While at it, update the description to mention the
- fact that only refresh tags with refresh times above 9
- seconds are covered.
- </p>
- </li>
- <li>
- <p>
- 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.
- </p>
- </li>
- <li>
- <p>
- ijbswa-Feature Requests-3006719 - Block 160x578 Banners.
- </p>
- </li>
- <li>
- <p>
- Block another omniture tracking domain.
- </p>
- </li>
- <li>
- <p>
- Added a range-requests tagger.
- </p>
- </li>
- <li>
- <p>
- 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@.
- </p>
- </li>
- </ul>
+ <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>
- Documentation improvements:
- </p>
- <ul>
- <li>
- <p>
- Explicitly mention how to match all URLs.
- </p>
- </li>
- <li>
- <p>
- Consistently recommend socks5 in the Tor FAQ entry and
- mention its advantage compared to socks4a. Reported by David
- in #2960129.
- </p>
- </li>
- <li>
- <p>
- Slightly improve the explanation of why filtering may appear
- slower than it is.
- </p>
- </li>
- <li>
- <p>
- Grammar fixes for the ACL section.
- </p>
- </li>
- <li>
- <p>
- Fixed a link to the 'intercepting' entry and add another one.
- </p>
- </li>
- <li>
- <p>
- Rename the 'Other' section to 'Mailing Lists' and reword it
- to make it clear that nobody is forced to use the trackers
- </p>
- </li>
- <li>
- <p>
- Note that 'anonymously' posting on the trackers may not
- always be possible.
- </p>
- </li>
- <li>
- <p>
- Suggest to enable debug 32768 when suspecting parsing
- problems.
- </p>
- </li>
- </ul>
+ <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>
- Privoxy-Log-Parser improvements:
- </p>
- <ul>
- <li>
- <p>
- Gather statistics for ressources, methods, and HTTP versions
- used by the client.
- </p>
- </li>
- <li>
- <p>
- Also gather statistics for blocked and redirected requests.
- </p>
- </li>
- <li>
- <p>
- Provide the percentage of keep-alive offers the client
- accepted.
- </p>
- </li>
- <li>
- <p>

- <li>
- <p>

- with a decimal number.
- </p>
- </li>
- <li>
- <p>
- Accept and ignore: Looks like we got the last chunk together

- </li>
- <li>
- <p>
- Accept and ignore: Continue hack in da house.
- </p>

- </li>
- <li>
- <p>

+ <p><tt class="FILENAME">standard.action</tt> has been merged into

</li>
+
<li>
- <p>
- Code cleanups:
- </p>
- <ul>
- <li>
- <p>
- Remove the next member from the client_state struct. Only the
- main thread needs access to all client states so give it its
- own struct.
- </p>
- </li>
- <li>
- <p>
- Garbage-collect request_contains_null_bytes().
- </p>
- </li>
- <li>
- <p>
- Ditch redundant code in unload_configfile().
- </p>
- </li>
- <li>
- <p>
- Ditch LogGetURLUnderCursor() which doesn't seem to be used
- anywhere.
- </p>
- </li>
- <li>
- <p>
- In write_socket(), remove the write-only variable write_len
- in an ifdef __OS2__ block. Spotted by cppcheck.
- </p>
- </li>
- <li>
- <p>
- In connect_to(), don't declare the variable 'flags' on OS/2
- where it isn't used. Spotted by cppcheck.
- </p>
- </li>
- <li>
- <p>
- Limit the scope of various variables. Spotted by cppcheck.
- </p>
- </li>
- <li>
- <p>
- In add_to_iob(), turn an interestingly looking for loop into
- a boring while loop.
- </p>
- </li>
- <li>
- <p>
- Code cleanup in preparation for external filters.
- </p>
- </li>
- <li>
- <p>
- In listen_loop(), mention the socket on which we accepted the
- connection, not just the source IP address.
- </p>
- </li>
- <li>
- <p>
- In write_socket(), also log the socket we're writing to.
- </p>
- </li>
- <li>
- <p>
- In log_error(), assert that escaped characters get logged
- completely or not at all.
- </p>
- </li>
- <li>
- <p>
- In log_error(), assert that ival and sval have reasonable
- values. There's no reason not to abort() if they don't.
- </p>
- </li>
- <li>
- <p>
- Remove an incorrect cgi_error_unknown() call in a
- cannot-happen-situation in send_crunch_response().

- crunch_reason to the beginning.
- </p>
- </li>
- <li>
- <p>
- Turn http_response.reason into an enum and rename it to
- http_response.crunch_reason.
- </p>
- </li>
- <li>
- <p>
- Silence a 'gcc (Debian 4.3.2-1.1) 4.3.2' warning on i686
- GNU/Linux.
- </p>
- </li>
- <li>
- <p>
- 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.
- </p>
- </li>
- </ul>
+ <p>In the default configuration only fatal errors are logged now.
+ You can change that in the <a href="config.html#DEBUG">debug

+ more verbose logging until you verified that the new <span class=
+ "APPLICATION">Privoxy</span> version is working as expected.</p>
</li>
+
<li>
- <p>
- GNUmakefile improvements:
- </p>
- <ul>
- <li>
- <p>
- Use $(SSH) instead of ssh, so one only needs to specify a
- username once.
- </p>
- </li>
- <li>
- <p>
- Removed references to the action feedback thingy that hasn't
- been working for years.
- </p>
- </li>
- <li>
- <p>
- Consistently use shell.sourceforge.net instead of
- shell.sf.net so one doesn't need to check server fingerprints
- twice.
- </p>
- </li>
- <li>
- <p>
- Removed GNUisms in the webserver and webactions targets so
- they work with standard tar.
- </p>
- </li>
- </ul>
+ <p>Three other config file settings are now off by default:
+ <a href="config.html#ENABLE-REMOTE-TOGGLE">enable-remote-toggle</a>,
