This should significantly reduce the number of - connections problems several users reported. -- If the server doesn't specify how long the connection stays alive, - Privoxy errs on the safe side of caution and assumes it's only a second. -- The error pages for connection timeouts or missing server data use a - Last-Modified date in the past. Retry attempts are detected and Privoxy - removes the If-Modified-Since header to prevent the server from responding - with status code 304 in which case the client would reuse the error message. -- Setting keep-alive-timeout to 0 disables keep-alive support. Previously - Privoxy would claim to allow persistence but not reuse the connection. -- Pipelined requests are less likely to be mistaken for the request - body of the previous request. Note that Privoxy still has no real - pipeline support and will either serialize pipelined requests or - drop them in which case the client has to resent them. -- Fixed a crash on some Windows versions when header randomization - is enabled and the date couldn't be parsed. -- Privoxy's keep-alive timeout for the current connection is reduced - to the one specified in the client's Keep-Alive header. -- For HTTP/1.1 requests, Privoxy implies keep-alive support by not - setting any Connection header instead of using 'Connection: keep-alive'. -- If the socket isn't reusable, Privoxy doesn't temporarily waste - a socket slot to remember the connection. -- If keep-alive support is disabled but compiled in, the client's - Keep-Alive header is removed. -- Fixed a bug on mingw32 where downloading large files failed if - keep-alive support was enabled. -- Fixed a bug that (at least theoretically) could cause log - timestamps to be occasionally off by about a second. -- No Proxy-Connection header if added if there already is one. -- The configure script respects the $PATH variable when searching - for groups and id. - -*** Version 3.0.13 beta *** - -- Added IPv6 support. Thanks to Petr Pisar who not only provided - the initial patch but also helped a lot with the integration. -- Added client-side keep-alive support. -- The connection sharing code is only used if the connection-sharing - option is enabled. -- The max-client-connections option has been added to restrict - the number of client connections below a value enforced by - the operating system. -- Fixed a regression reintroduced in 3.0.12 that could cause - crashes on mingw32 if header date randomization was enabled. -- Compressed content with extra fields couldn't be decompressed - and would get passed to the client unfiltered. This problem - has only be detected through statical analysis with clang as - nobody seems to be using extra fields anyway. -- If the server resets the Connection after sending only the headers - Privoxy forwards what it got to the client. Previously Privoxy - would deliver an error message instead. -- Error messages in case of connection timeouts use the right - HTTP status code. -- If spawning a child to handle a request fails, the client - gets an error message and Privoxy continues to listen for - new requests right away. -- The error messages in case of server-connection timeouts or - prematurely closed server connections are now template-based. -- If zlib support isn't compiled in, Privoxy no longer tries to - filter compressed content unless explicitly asked to do so. -- In case of connections that are denied based on ACL directives, - the memory used for the client IP is no longer leaked. -- Fixed another small memory leak if the client request times out - while waiting for client headers other than the request line. -- The client socket is kept open until the server socket has - been marked as unused. This should increase the chances that - the still-open connection will be reused for the client's next - request to the same destination. Note that this only matters - if connection-sharing is enabled. -- A TODO list has been added to the source tarballs to give potential - volunteers a better idea of what the current goals are. + +- Security/Reliability: + - Fixed memory leaks when a response is buffered and the buffer + limit is reached or Privoxy is running out of memory. + Commits bbd53f1010b and 4490d451f9b.

To enable this, configure with + --enable-pcre-host-patterns. + Sponsored by: Robert Klemme + - Added "Cross-origin resource sharing" (CORS) support. + This allows to access Privoxy's CGI interface via JavaScript from + another domain (white-listed with the new cors-allowed-origin directive). + Based on a patch by Nedzad Hrnjica. + Sponsored by: Robert Klemme. + - Add SOCKS5 username/password support. + Based on a patch by Sam, improved by Ivan Romanov. + Closes Patch#141 and solves TODO#105. + - Bump the maximum number of action and filter files + to 100 each. + Sponsored by: Robert Klemme + - Fixed handling of filters with "split-large-forms 1" + when using the CGI editor. + Reported by withoutname in #921. + - Better detect a mismatch of connection details when + figuring out whether or not a connection can be reused. + - Don't send a "Connection failure" message instead of the + "DNS failure" message. + Sponsored by: Robert Klemme + - Let LOG_LEVEL_REQUEST log all requests. Previously unencrypted + requests were only logged with LOG_LEVEL_REQUEST when they weren't + crunched (in which case they were logged with LOG_LEVEL_CRUNCH). + This was documented behaviour, but logging all requests seems more useful. + - Fixed locking around localtime() and gmtime(). + - Removed OS/2 support.
