+ Announcing Privoxy 3.0.34 stable
+--------------------------------------------------------------------
-This is the first stable release since 3.0.12. It mainly contains
-bugfixes for the previous betas which introduced IPv6 support,
-improved keep-alive support and a bunch of minor improvements.
+Privoxy 3.0.34 fixes a few minor bugs and comes with a couple of
+general improvements and new features.
-See http://www.privoxy.org/3.0.15/user-manual/whatsnew.html for details.
+Please note that Google started to bounce messages from the Privoxy
+mailing lists a couple of months ago. As a result gmail users have
+been unsubscribed by Mailman. If you are affected by this, please
+resubscribe with a different mail address. The Privoxy project has
+limited resources and limited time to investigate an issue that

-ChangeLog for Privoxy
+ChangeLog for Privoxy 3.0.34
--------------------------------------------------------------------
-*** Version 3.0.16 stable ***
-
-- Added the config file option handle-as-empty-doc-returns-ok to
- work around Firefox bug #492459, which causes Firefox to hang
- if JavaScripts are blocked in certain situations. The option is
- enabled in the default config file.
-- Added the config file option default-server-timeout to control the
- assumed default server timeout. Since Privoxy no longer returns
- an error message for connection resets on reused client connections,
- assuming larger server timeout values appears to actually work
- pretty well as long as connections aren't shared.
-- Added optional support for FreeBSD's accf_http(9). Use the
- configure option --enable-accept-filter to enable it.
-- Added fancier Privoxy icons for win32. Contributed by Jeff H.
-- In daemon mode, fd 0, 1 and 2 are bound to /dev/null.
-- Resolve localhost using whatever address family the operating
- system feels like. Previous betas would try to use IPv4 as this
- is what most users expect, but this didn't work reliably on
- GNU/Linux systems.
-- In the action lists on CGI pages, actions and their parameters are
- no longer separated with a space. The action file parser doesn't
- actually allow this and will throw an invalid syntax error if actions
- and parameters in the action files are separated. Not adding the
- spaces means copy and pasting CGI output into the action files works.
-- The default keep-alive timeout has been reduced to 5 seconds to work
- around hangs in clients that treat the proxy like any other host and
- stop allowing any new connections if the "maximum number of
- connections per host" is reached.
-- Several webbug URLs that look like they are leading to images are now
- blocked as image instead of empty documents. Doing the latter causes
- WebKit-based clients to show a "missing image" icon which may mess up
- the layout.
-- The no-such-domain template is used for DNS resolution
- problems with FEATURE_IPV6_SUPPORT enabled. Previously the
- connect-failed template was used. Reported by 'zebul666'.
-- Accepts quoted expiration dates even though RFC 2109 10.1.2
- doesn't seem to allow them. Reported anonymously.
-- Don't try to forget connections if connection sharing is disabled.
- This wasn't a real problem but caused an unnecessary log message.
-- The still undocumented --enable-extended-host-patterns configure
- option has a better description.
-- Fixed an error message that would claim a write to the server
- failed when actually writing to the client failed.
-- Log the crunch reason before trying to write to the client.
- The log is easier to read that way.
-- Several log messages about client connections also mention
- the socket number.
-- handle-as-empty-document no longer depends on the image blocking
- code being enabled.
-- Privoxy-Log-Parser is roughly 40% faster in highlighting mode.
-- uagen, a Firefox User-Agent generator for Privoxy and Mozilla
- browsers has been imported and is available in the tarball's
- tools directory.
-- The scripts in the tools directory treat unknown parameters
- as fatal errors.
-
-*** Version 3.0.15 beta ***
-
-- In case of missing server data, no error message is send to the
- client if the request arrived on a reused connection. The client
- is then supposed to silently retry the request without bothering
- the user. This should significantly reduce the frequency of the
- "No server or forwarder data received" error message many users
- reported.
-- More reliable detection of prematurely closed client sockets
- with keep-alive enabled.
-- FEATURE_CONNECTION_KEEP_ALIVE is decoupled from
- FEATURE_CONNECTION_SHARING and now available on
- all platforms.
-- Improved handling of POST requests on reused connections.
- Should fix problems with stalled connections after submitting
- form data with some browser configurations.
-- Fixed various latency calculation issues.
-- Allows the client to pass NTLM authentication requests to a
- forwarding proxy. This was already assumed and hinted to work
- in 3.0.13 beta but actually didn't. Now it's confirmed to work
- with IE, Firefox and Chrome.
- Thanks to Francois Botha and Wan-Teh Chang
-- Fixed a calculation problem if receiving the server headers
- takes more than two reads, that could cause Privoxy to terminate
- the connection prematurely. Reported by Oliver.
-- Compiles again on platforms such as OpenBSD and systems
- using earlier glibc version that don't support AI_ADDRCONFIG.
- Anonymously submitted in #2872591.
-- A bunch of MS VC project files and Suse and Redhat RPM spec
- files have been removed as they were no longer maintained for
- quite some time.
-- Overly long action lines are properly rejected with a proper
- error message. Previously they would be either rejected as
- invalid or cause a core dump through abort().
-- Already timed-out connections are no longer temporarily remembered.
- They weren't reused anyway, but wasted a socket slot.
-- len refers to the number of bytes actually read which might
- differ from the ones received. Adjust log messages accordingly.
-- The optional JavaScript on the CGI page uses encodeURIComponent()
- instead of escape() which doesn't encode all characters that matter.
- Anonymously reported in #2832722.
-- Fix gcc45 warnings in decompress_iob().
-- Various log message improvements.
-- Privoxy-Regression-Test supports redirect tests.
-- Privoxy-Log-Parser can gather some connection statistics.
-
-*** Version 3.0.14 beta ***
-
-- The latency is taken into account when evaluating whether or not to
- reuse a connection. 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 tarball to give potential
- volunteers a better idea of what the current goals are.
+- Bug fixes:
+ - Improve the handling of chunk-encoded responses by buffering the data
+ even if filters are disabled and properly keeping track of where the
+ various chunks are supposed to start and end. Previously Privoxy would
+ merely check the last bytes received to see if they looked like the
+ last-chunk. This failed to work if the last-chunk wasn't received in one
+ read and could also result in actual data being misdetected
+ as last-chunk.
+ Should fix: SF support request #1739.
+ Reported by: withoutname.
+ - remove_chunked_transfer_coding(): Refuse to de-chunk invalid data
+ Previously the data could get corrupted even further.
+ Now we simply pass the unmodified data to the client.
+ - gif_deanimate(): Tolerate multiple image extensions in a row.
+ This allows to deanimate all the gifs on:
+ https://commons.wikimedia.org/wiki/Category:Animated_smilies
+ Fixes SF bug #795 reported by Celejar.
+ - OpenSSL generate_host_certificate(): Use X509_get_subject_name()
+ instead of X509_get_issuer_name() to get the issuer for generated
+ website certificates so there are no warnings in the browser when using
+ an intermediate CA certificate instead of a self-signed root certificate.
+ Problem reported and patch submitted by Chakib Benziane.
+ - can_filter_request_body(): Fix a log message that contained a spurious u.
+ - handle_established_connection(): Check for pending TLS data from the client
+ before checking if data is available on the connection.
+ The TLS library may have already consumed all the data from the client
+ response in which case poll() and select() will not detect that data is
+ available to be read.
+ Sponsored by: Robert Klemme.
+ - ssl_send_certificate_error(): Don't crash if there's no certificate
+ information available. This is only relevant when Privoxy is built with
+ wolfSSL 5.0.0 or later (code not yet published). Earlier wolfSSL versions
+ or the other TLS backends don't seem to trigger the crash.
+ - socks5_connect(): Add support for target hosts specified as IPv4 address
+ Previously the IP address was sent as domain.
+
+- General improvements:
+ - Add a client-body-tagger action which creates tags based on
+ the content of the request body.
+ Sponsored by: Robert Klemme.
+ - When client-body filters are enabled, buffer the whole request
+ before opening a connection to the server.
+ Makes it less likely that the server connection times out
+ and we don't open a connection if the buffering fails anyway.
+ Sponsored by: Robert Klemme.
+ - Add periods to a couple of log messages.
+ - accept_connection(): Add missing space to a log message.
+ - Initialize ca-related defaults with strdup_or_die() so errors
+ aren't silently ignored.
+ - make_path: Use malloc_or_die() in cases where allocation errors
+ were already fatal anyway.
+ - handle_established_connection(): Improve an error message slightly.
+ - receive_client_request(): Reject https URLs without CONNECT request.
+ - Include all requests in the statistics if mutexes are available.
+ Previously in case of reused connections only the last request got
+ counted. The statistics still aren't perfect but it's an improvement.
+ - Add read_socks_reply() and start using it in socks5_connect()
+ to apply the socket timeout more consistently.
+ - socks5_connect(): Deal with domain names in the socks reply
+ - Add a filter for bundeswehr.de that hides the cookie and
+ privacy info banner.
+
+- Action file improvements:
+ - Disable filter{banners-by-size} for .freiheitsfoo.de/.
+ - Disable filter{banners-by-size} for freebsdfoundation.org/.
+ - Disable fast-redirects for consent.youtube.com/.
+ - Block requests to ups.xplosion.de/.
+ - Block requests for elsa.memoinsights.com/t.
+ - Fix a typo in a test.
+ - Disable fast-redirects for launchpad.net/.
+ - Unblock .eff.org/.
+ - Stop unblocking .org/.*(image|banner) which appears to be too generous
+ It let requests like:
+ https://stats.noblogs.org/piwik.php?action_name=anti%20gentrifizierungs%20fest&idsite=10175&rec=1&r=220192&h=17&m=7&s=44&url=https%3A%2F%2Fmuellemcalling.noblogs.org%2F&urlref=https%3A%2F%2Fmuellemcalling.noblogs.org%2Finfostande%2F&_id=&_idn=1&_refts=0&send_image=0&cookie=1&res=1366x768&pv_id=eqr7jX&pf_net=7&pf_srv=3&pf_tfr=2281&pf_dm1=156
+ pass.
+ The example URL http://www.gnu.org/graphics/gnu-head-banner.png is
+ already unblocked due to .gnu.org being unblocked.
+ - Unblock adfd.org/.
+ - Disable filter{banners-by-link} for .eff.org/.
+ - Block requests to odb.outbrain.com/.
+ - Disable fast-redirects for .gandi.net/.
+ - Disable fast-redirects{} for .onion/.*/status/.
+ - Disable fast-redirects{} for twitter.com/.*/status/.
+ - Unblock pinkstinks.de/.
+ - Disable fast-redirects for .hagalil.com/.
+
+- Privoxy-Log-Parser:
+ - Bump version to 0.9.5.
+ - Highlight more log messages.
+ - Highlight the Crunch reason only once. Previously the "crunch reason"
+ could also be highlighted when the URL contained a matching string.
+ The real crunch reason only occurs once per line, so there's no need
+ to continue looking for it after it has been found once.
+ While at it, add a comment with an example log line.
+
+- uagen:
+ - Bump version to 1.2.4.
+ - Update BROWSER_VERSION and BROWSER_REVISION to 102.0
+ to match the User-Agent of the current Firefox ESR.
+ - Explicitly document that changing the 'Gecko token' is suspicious.
+ - Consistently use a lower-case 'c' as copyright symbol.
+ - Bump copyright.
+ - Add 'aarch64' as Linux architecture.
+ - Add OpenBSD architecture 'arm64'.
+ - Stop using sparc64 as FreeBSD architecture.
+ It hasn't been supported for a while now.
+
+- Build system:
+ - Makefile: Add a 'dok' target that depends on the 'error' target
+ to show the "You are not using GNU make or did nor run configure"
+ message.
+ - configure: Fix --with-msan option.
+ Also (probably) reported by Andrew Savchenko.
+
+- macOS build system:
+ - Enable HTTPS inspection when building the macOS binary
+ (using OpenSSL as TLS library).
+
+- Documentation:
+ - Add OpenSSL to the list of libraries that may be licensed under the
+ Apache 2.0 license in which case the linked Privoxy binary has to be
+ distributed under the GPLv3 or later.
+ - config: Fix the documented ca-directory default value.
+ Reported by avoidr.
+ - Rebuild developer-manual and tidy with 'HTML Tidy for FreeBSD version 5.8.0'.
+ - Update developer manual with new macOS packaging instructions.
+ - Note that the FreeBSD installation instructions work for
+ ElectroBSD as well.
+ - Note that FreeBSD/ElectroBSD users can try to install Privoxy
+ as binary package using 'pkg'.
