ChangeLog for Privoxy
--------------------------------------------------------------------
-*** Version 3.0.20 Beta ***
+*** Version 3.0.20 beta ***
- Bug fixes:
+ - 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.
- 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.
- - Fix a Windows-specific log viewer thread safety issue.
+ - 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.
+ - The default-server-timeout and socket-timeout directives accept 0 as
+ valid value.
+ - 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.
- - Let fatal_error() write to the logfile right away, before showing the
- Windows-specific error message which blocks until the user acknowledges
- it, thus complicating automatic error detection.
- Reported by Adriaan in #3593603.
- - Fix the --disable-ipv6-support configure option for the Windows platform.
- - In socks5_connect(), do not try to print a negative number of socks
- response bytes if the read() for the socks5 negotiation failed
- completely. It's an API violation and can trigger an assert() in debug
- builds with "debug 2" enabled. Except for the assert(), log_error()
- already handled negative %N values gracefully so this commit only makes a
- difference for debug builds.
+ - Fix the compilation on Windows when configured without IPv6 support.
+ - Fix an assertion that could cause debug builds to abort() in case of
+ socks5 connection failures with "debug 2" enabled.
- Fix an assertion that could cause debug builds to abort() if a filter
contained nul bytes in the replacement text.
- General improvements:
- - New debug log level 65536 which logs all actions that were applied to each
- request that Privoxy acts upon.
- - New directive client-header-order can be used to forward client headers in
- a different order than that in which they arrived.
- - New directive tolerate-pipelining can be used to enable 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. At the moment this is only done if the current
- request is known to have no body.
- - New --config-test option lets Privoxy exit after checking whether or not
+ - Significantly improved keep-alive support for both client and server
+ connections.
+ - New debug log level 65536 which logs all actions that were applied to
+ the request.
+ - New directive client-header-order to forward client headers in a
+ different order than the one in which they arrived.
+ - 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.
+ - 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. Logging the problem to the logfile if one is configured and
- --no-daemon isn't used could be considered non-intuitive and might also
- clobber messages emitted by an already running instance. Based on a patch
- by Ramkumar Chinchani.
- - Add limit-cookie-lifetime{} action. It can be used to let cookies expire
- before the end of the session. limit-cookie-lifetime{0} creates session
- cookies and can thus replace the session-cookies-only action in the future.
- Idea originally suggested by Rick Sykes in #1049575.
- - Increase the maximum number of actions files from 10 to 30. This is set by
- the compiler directive MAX_AF_FILES so could always be modified by
- recompilation, but the default value was too low since an unused file slot
- is pretty inexpensive.
- - Significantly improved reuse of open connections.
+ still apply. Based on a patch by Ramkumar Chinchani.
+ - New limit-cookie-lifetime{} action to let cookies expire before the end
+ of the session. Suggested by Rick Sykes in #1049575.
+ - 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.
- 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
- 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. This might improve compatibility with Opera (#3464439).
- - Use new drain_and_close_socket() when closing client sockets in serve().
- Hopefully this fixes the page truncation issue reported with Opera in
- #3464439. Apparently on some platforms immediately closing a client socket
- with both unread and written-but-not-yet-transmitted data may result in the
- connection being torn down prematurely, in which case the client ends up
- with an incomplete response. To prevent this, drain_and_close_socket()
- shuts down our side of the connection (on platforms with shutdown()),
- drains the unread data on the socket and finally calls close_socket().
- - 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.
- - Stop considering client sockets tainted after receving a request with body.
+ should be expected.
+ - 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.
- 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.
- - Only remove duplicated headers when filters are enabled. If they are not it
- doesn't cause ill effects and the user might not want it. While at it,
- downgrade the removal message to LOG_LEVEL_HEADER to clarify that it's not
+ - 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.
- - Accept a default-server-timeout of 0. It's the default after all.
- - Accept a socket-timeout value of 0 seconds. Impatience isn't necessarily a
- syntax problem.
- - Set the socket option SO_LINGER for the client socket in
- accept_connection(). This should further reduce the chances of the client
- getting an incomplete response, even though Privoxy wrote it in its
- entirety to the socket.
- - Let serve() wait for keep-alive-timeout seconds for new requests. The
- server connection timeout is no longer relevant.
- - Improve connection handling when connection sharing is enabled.
- - Do not keep the client connection open if it has to be closed to mark the
- end of the response.
- - 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.
- - Use an enum for the type of the action value.
- - Rename action_name's member takes_value to value_type as it isn't used as
- boolean.
- - Turn family mismatches in match_sockaddr() into fatal errors
- - Let enlist_unique_header() verify that the caller didn't pass a header
- containing either \r or \n.
- - 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.
- - Use privoxy_tolower() instead of vanilla tolower() with manual casting of
- the argument.
+ - Set the socket option SO_LINGER for the client socket.
- Move several variable declarations to the beginning of their code block.
- It's how we usually do it and is apparently also required when compiling
- with gcc 2.95. Initial patch submitted by Simon South in #3564815.
- - Optionally let parse_header_time() 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:
- http://www.freebsd.org/cgi/query-pr.cgi?pr=173421
- - Attempt to work around (or at least reduce the) video playback issues with
- various Apple clients as reported in #3426305. In client_range(), let
- headers pass if the range starts at the beginning.
+ It's required when compiling with gcc 2.95 which is still used on some
+ platforms. Initial patch submitted by Simon South in #3564815.

+ - 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.
- 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.

-- Action file improvements:
- - Remove the comment that indicated that updated versions of this file are
- released on their own.
- Allow closing curly braces as part of action values as long as they are
escaped.
+ - 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.
+ - 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@.
+ - Decrease the chances of parse failures after requests with unsupported
+ methods were sent to the CGI interface.

- GNUmakefile improvements:
- The dok-tidy target no longer taints documents with a tidy-mark
- 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.
- Ditch a pointless '-r' passed to rm to delete files.
- - Prevent completely empty lines in configure and try to unfold
- unintentional line breaks.
- - Let the config-file target optimistically update the original. Most of the
- issues are fixed now and it makes diffing with git easier.
+ - The config-file target now requires less manual intervention and updates

- Change WDUMP to generate ASCII. Add WDUMP_UTF8 to allow UTF-8 in the
AUTHORS file so the names are right.
- Stop pretending that lynx and links are supported for the documentation.
