ChangeLog for Privoxy
--------------------------------------------------------------------
*** Version 3.0.19 Stable ***
- Bug fixes:
- Prevent a segmentation fault when de-chunking buffered content.
It could be triggered by malicious web servers if Privoxy was
configured to filter the content and running on a platform
where SIZE_T_MAX isn't larger than UINT_MAX, which probably
includes most 32-bit systems. On those platforms, all Privoxy
versions before 3.0.19 appear to be affected.
To be on the safe side, this bug should be presumed to allow
code execution as proving that it doesn't seems unrealistic.
- Do not expect a response from the SOCKS4/4A server until it
got something to respond to. This regression was introduced
in 3.0.18 and prevented the SOCKS4/4A negotiation from working.
Reported by qqqqqw in #3459781.
- General improvements:
- Fix an off-by-one in an error message about connect failures.
- Use a GNUMakefile variable for the webserver root directory and
update the path. Sourceforge changed it which broke various
web-related targets.
- Update the CODE_STATUS description.
*** Version 3.0.18 Stable ***
- Bug fixes:
- If a generated redirect URL contains characters RFC 3986 doesn't
permit, they are (re)encoded. Not doing this makes Privoxy versions
from 3.0.5 to 3.0.17 susceptible to HTTP response splitting (CWE-113)
attacks if the +fast-redirects{check-decoded-url} action is used.
- Fix a logic bug that could cause Privoxy to reuse a server
socket after it got tainted by a server-header-tagger-induced
block that was triggered before the whole server response had
been read. 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.
- 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 which terminates the client connection after detecting
that the whole body has been received it doesn't really matter,
but with clients that don't the connection would be kept open until
it timed out.
- 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.
So far this has only been reproduced 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.
- Disable filters if SDCH compression is used unless filtering is forced.
If SDCH was combined with a supported compression algorithm, Privoxy
previously could try to decompress it and ditch the Content-Encoding
header even though the SDCH compression wasn't dealt with.
Reported by zebul666 in #3225863.
- 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.
- If forwarded-connect-retries is set, only retry if Privoxy is actually
forwarding the request. Previously direct connections would be retried
as well.
- Fixed a small memory leak when retrying connections with IPv6
support enabled.
- 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).
- If the --user argument user[.group] contains a dot, always bail out
if no group has been specified. Previously the intended, but undocumented
(and apparently untested), behaviour was to try interpreting the whole
argument as user name, but the detection was flawed and checked for '0'
instead of '\0', thus merely preventing group names beginning with a zero.
- In html_code_map[], use a numeric character reference instead of '
which wasn't standardized before XHTML 1.0.
- Fix an invalid free when compiled with FEATURE_GRACEFUL_TERMINATION
and shut down through http://config.privoxy.org/die
- In get_actions(), fix the "temporary" backwards compatibility hack
to accept block actions without reason.
It also covered other actions that should be rejected as invalid.
Reported by Billy Crook.
- General improvements:
- Privoxy can (re)compress buffered content before delivering
it to the client. Disabled by default as most users wouldn't
benefit from it.
- 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 off
by additionally using a +redirect{} pcrs command.
Initial patch submitted by Jamie Zawinski in #3429848.
- 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.
- Allow to bind to multiple separate addresses.
Patch set submitted by Petr Pisar in #3354485.
- Set socket_error to errno if connecting fails in rfc2553_connect_to().
Previously rejected direct connections could be incorrectly reported
as DNS issues if Privoxy was compiled with IPv6 support.
- 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 known problems.
- When compiled without FEATURE_FAST_REDIRECTS, do not silently
ignore +fast-redirect{} directives
- 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
- 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.
- 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.
- In get_last_url(), do not bother trying to decode URLs that do
not contain at least one '%' sign. It reduces the log noise and
a number of unnecessary memory allocations.
- In case of SOCKS5 failures, dump the socks response in the log message.
- Simplify the signal setup in main().
- Streamline socks5_connect() slightly.
- In socks5_connect(), require a complete socks response from the server.
Previously Privoxy didn't care how much data the server response
contained as long as the first two bytes contained the expected
values. While at it, shrink the buffer size so Privoxy can't read
more than a whole socks response.
- In chat(), do not bother to generate a client request in case of
direct CONNECT requests. It will not be used anyway.
- Reduce server_last_modified()'s stack size.
- Shorten get_http_time() by using strftime().
- Constify the known_http_methods pointers in unknown_method().
- Constify the time_formats pointers in parse_header_time().
- Constify the formerly_valid_actions pointers in action_used_to_be_valid().
- Introduce a GNUMakefile MAN_PAGE variable that defaults to privoxy.1.
The Debian package uses section 8 for the man page and this
should simplify the patch.
- Deduplicate the INADDR_NONE definition for Solaris by moving it to jbsockets.h
- In block_url(), ditch the obsolete workaround for ancient Netscape versions
that supposedly couldn't properly deal with status code 403.
- Remove a useless NULL pointer check in load_trustfile().
- Remove two useless NULL pointer checks in load_one_re_filterfile().
- Change url_code_map[] from an array of pointers to an array of arrays
It removes an unnecessary layer of indirection and on 64bit system reduces
the size of the binary a bit.
- Fix various typos. Fixes taken from Debian's 29_typos.dpatch by Roland Rosenfeld.
- Add a dok-tidy GNUMakefile target to clean up the messy HTML
generated by the other dok targets.
- GNUisms in the GNUMakefile have been removed.
- Change the HTTP version in static responses to 1.1
- Synced config.sub and config.guess with upstream
2011-11-11/386c7218162c145f5f9e1ff7f558a3fbb66c37c5.
- Add a dedicated function to parse the values of toggles. Reduces duplicated
code in load_config() and provides better error handling. Invalid or missing
toggle values are now a fatal error instead of being silently ignored.
- Terminate HTML lines in static error messages with \n instead of \r\n.
- Simplify cgi_error_unknown() a bit.
- In LogPutString(), don't bother looking at pszText when not
actually logging anything.
- Change ssplit()'s fourth parameter from int to size_t.
Fixes a clang complaint.
- Add a warning that the statistics currently can't be trusted.
Mention Privoxy-Log-Parser's --statistics option as
an alternative for the time being.
- In rfc2553_connect_to(), start setting cgi->error_message on error.
- Change the expected status code returned for http://p.p/die depending
on whether or not FEATURE_GRACEFUL_TERMINATION is available.
- In cgi_die(), mark the client connection for closing.
If the client will fetch the style sheet through another connection
it gets the main thread out of the accept() state and should thus
trigger the actual shutdown.
- Add a proper CGI message for cgi_die().
- Don't enforce a logical line length limit in read_config_line().
- Slightly refactor server_last_modified() to remove useless gmtime*() calls.
- In get_content_type(), also recognize '.jpeg' as JPEG extension.
- Add '.png' to the list of recognized file extensions in get_content_type().
- In block_url(), consistently use the block reason "Request blocked by Privoxy"
In two places the reason was "Request for blocked URL" which hides the
fact that the request got blocked by Privoxy and isn't necessarily
correct as the block may be due to tags.
- In listen_loop(), reload the configuration files after accepting
a new connection instead of before.
Previously the first connection that arrived after a configuration
change would still be handled with the old configuration.
- In chat()'s receive-data loop, skip a client socket check if
the socket will be written to right away anyway. This can
increase the transfer speed for unfiltered content on fast
network connections.
- The socket timeout is used for SOCKS negotiations as well which
previously couldn't timeout.
- Don't keep the client connection alive if any configuration file
changed since the time the connection came in. This is closer to
Privoxy's behaviour before keep-alive support for client connection
has been added and also less confusing in general.
- Treat all Content-Type header values containing the pattern
'script' as a sign of text. Reported by pribog in #3134970.
- Action file improvements:
- 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.
- Remove -prevent-compression from the fragile alias. It's no longer
used anywhere by default and isn't known to break stuff anyway.
- Add a (disabled) section to block various Facebook tracking URLs.
Reported by Dan Stahlke in #3421764.
- Add a (disabled) section to rewrite and redirect click-tracking
URLs used on news.google.com.
Reported by Dan Stahlke in #3421755.
- Unblock linuxcounter.net/.
Reported by Dan Stahlke in #3422612.
- Block 'www91.intel.com/' which is used by Omniture.
Reported by Adam Piggott in #3167370.
- Disable the handle-as-empty-doc-returns-ok option and mark it as deprecated.
Reminded by tceverling in #2790091.
- Add ".ivwbox.de/" to the "Cross-site user tracking" section.
Reported by Nettozahler in #3172525.
- Unblock and fast-redirect ".awin1.com/.*=http://".
Reported by Adam Piggott in #3170921.
- Block "b.collective-media.net/".
- Widen the Debian popcon exception to "qa.debian.org/popcon".
Seen in Debian's 05_default_action.dpatch by Roland Rosenfeld.
- Block ".gemius.pl/" which only seems to be used for user tracking.
Reported by johnd16 in #3002731. Additional input from Lee and movax.
- Disable banners-by-size filters for '.thinkgeek.com/'.
The filter only seems to catch pictures of the inventory.
- Block requests for 'go.idmnet.bbelements.com/please/showit/'.
Reported by kacperdominik in #3372959.
- Unblock adainitiative.org/.
- Add a fast-redirects exception for '.googleusercontent.com/.*=cache'.
- Add a fast-redirects exception for webcache.googleusercontent.com/.
- Unblock http://adassier.wordpress.com/ and http://adassier.files.wordpress.com/.
- Filter file improvements:
- Let the yahoo filter hide '.ads'.
- Let the msn filter hide overlay ads for Facebook 'likes' in search
results and elements with the id 's_notf_div'. They only seem to be
used to advertise site 'enhancements'.
- Let the js-events filter additionally disarm setInterval().
Suggested by dg1727 in #3423775.
- Documentation improvements:
- Clarify the effect of compiling Privoxy with zlib support.
Suggested by dg1727 in #3423782.
- Point out that the SourceForge messaging system works like a black
hole and should thus not be used to contact individual developers.
- Mention some of the problems one can experience when not explicitly
configuring an IP addresses as listen address.
- Explicitly mention that hostnames can be used instead of IP addresses
for the listen-address, that only the first address returned will be
used and what happens if the address is invalid.
Requested by Calestyo in #3302213.
- Log message improvements:
- If only the server connection is kept alive, do not pretend to
wait for a new client request.
- Remove a superfluous log message in forget_connection().
- In chat(), properly report missing server responses as such
instead of calling them empty.
- In forwarded_connect(), fix a log message nobody should ever see.
- Fix a log message in socks5_connect(), a failed write operation
was logged as failed read operation.
- Let load_one_actions_file() properly complain about a missing
'{' at the beginning of the file.
Simply stating that a line is invalid isn't particularly helpful.
- Do not claim to listen on a socket until Privoxy actually does.
Patch submitted by Petr Pisar #3354485
- Prevent a duplicated LOG_LEVEL_CLF message when sending out
the "no-server-data" response.
- Also log the client socket when dropping a connection.
- Include the destination host in the 'Request ... marked for
blocking. limit-connect{...} doesn't allow CONNECT ...' message
Patch submitted by Saperski in #3296250.
- Prevent a duplicated log message if none of the resolved IP
addresses were reachable.
- In connect_to(), do not pretend to retry if forwarded-connect-retries
is zero or unset.
- When a specified user or group can't be found, put the name in
single-quotes when logging it.
- In rfc2553_connect_to(), explain getnameinfo() errors better.
- Remove a useless log message in chat().
- When retrying to connect, also log the maximum number of connection
attempts.
- Rephrase a log message in compile_dynamic_pcrs_job_list().
Divide the error code and its meaning with a colon. Call the pcrs
job dynamic and not the filter. Filters may contain dynamic and
non-dynamic pcrs jobs at the same time. Only mention the name of
the filter or tagger, but don't claim it's a filter when it could
be a tagger.
- In a fatal error message in load_one_actions_file(), cover both
URL and TAG patterns.
- In pcrs_strerror(), properly report unknown positive error code
values as such. Previously they were handled like 0 (no error).
- In compile_dynamic_pcrs_job_list(), also log the actual error code as
pcrs_strerror() doesn't handle all errors reported by pcre.
- Don't bother trying to continue chatting if the client didn't ask for it.
Reduces log noise a bit.
- Make two fatal error message in load_one_actions_file() more descriptive.
- In cgi_send_user_manual(), log when rejecting a file name due to '/' or '..'.
- In load_file(), log a message if opening a file failed.
The CGI error message alone isn't too helpful.
- In connection_destination_matches(), improve two log messages
to help understand why the destinations don't match.
- Rephrase a log message in serve(). Client request arrival
should be differentiated from closed client connections now.
- In serve(), log if a client connection isn't reused due to a
configuration file change.
- Let mark_server_socket_tainted() always mark the server socket tainted,
just don't talk about it in cases where it has no effect. It doesn't change
Privoxy's behaviour, but makes understanding the log file easier.
- configure:
- Added a --disable-ipv6-support switch for platforms where support
is detected but doesn't actually work.
- Do not check for the existence of strerror() and memmove() twice
- Remove a useless test for setpgrp(2). Privoxy doesn't need it and
it can cause problems when cross-compiling.
- Rename the --disable-acl-files switch to --disable-acl-support.
Since about 2001, ACL directives are specified in the standard
config file.
- Update the URL of the 'Removing outdated PCRE version after the
next stable release' posting. The old URL stopped working after
one of SF's recent site "optimizations". Reported by Han Liu.
- Privoxy-Regression-Test:
- Added --shuffle-tests option to increase the chances of detection race conditions.
- Added a --local-test-file option that allows to use Privoxy-Regression-Test without Privoxy.
- Added tests for missing socks4 and socks4a forwarders.
- The --privoxy-address option now works with IPv6 addresses containing brackets, too.
- Perform limited sanity checks for parameters that are supposed to have numerical values.
- Added a --sleep-time option to specify a number of seconds to
sleep between tests, defaults to 0.
- Disable the range-requests tagger for tests that break if it's enabled.
- Log messages use the ISO 8601 date format %Y-%m-%d.
- Fix spelling in two error messages.
- In the --help output, include a list of supported tests and their default levels.
- Adjust the tests to properly deal with FEATURE_TOGGLE being disabled.
- Privoxy-Log-Parser:
- Perform limited sanity checks for command line parameters that
are supposed to have numerical values.
- Implement a --unbreak-lines-only option to try to revert MUA breakage.
- Accept and highlight: Added header: Content-Encoding: deflate
- Accept and highlight: Compressed content from 29258 to 8630 bytes.
- Accept and highlight: Client request arrived in time on socket 21.
- Highlight: Didn't receive data in time: a.fsdn.com:443
- Accept log messages with ISO 8601 time stamps, too.
- uagen:
- Bump generated Firefox version to 8.0.
- Only randomize the release date if the new --randomize-release-date
option is enabled. Firefox versions after 4 use a fixed date string
without meaning.
*** Version 3.0.17 Stable ***
- Fixed last-chunk-detection for responses where the body was small
enough to be read with the headers, 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.
- 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.
- 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.
- 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.
- The IPv6 code is enabled by default on Windows versions that support it.
Patch submitted by oCameLo in #2942729.
- In mingw32 versions, the user.filter file is reachable through the
GUI, just like default.filter is. Feature request 3040263.
- 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.
- 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.
- Privoxy logs when reading an action, filter or trust file.
- 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.
- CGI interface improvements:
- 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.
- Apostrophes in block messages no longer cause parse errors
when the blocked page is viewed with JavaScript enabled.
Reported by dg1727 in #3062296.
- Fix a bunch of anchors that used underscores instead of dashes.
- Allow to keep the client connection alive after crunching the previous request.
Already opened server connections can be kept alive, too.
- 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.
- Show the 404 CGI page if cgi_send_user_manual() is called while
local user manual delivery is disabled.
- Action file improvements:
- Enable user.filter by default. Suggested by David White in #3001830.
- Block .sitestat.com/. Reported by johnd16 in #3002725.
- Block .atemda.com/. Reported by johnd16 in #3002723.
- Block js.adlink.net/. Reported by johnd16 in #3002720.
- Block .analytics.yahoo.com/. Reported by johnd16 in #3002713.
- Block sb.scorecardresearch.com, too. Reported by dg1727 in #2992652.
- Fix problems noticed on Yahoo mail and news pages.
- Remove the too broad yahoo section, only keeping the
fast-redirects exception as discussed on ijbswa-devel@.
- Don't block adesklets.sourceforge.net. Reported in #2974204.
- Block chartbeat ping tracking. Reported in #2975895.
- Tag CSS and image requests with cautious and medium settings, too.
- 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.
- 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.
- 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.
- ijbswa-Feature Requests-3006719 - Block 160x578 Banners.
- Block another omniture tracking domain.
- Added a range-requests tagger.
- 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@.
- Documentation improvements:
- Explicitly mention how to match all URLs.
- Consistently recommend socks5 in the Tor FAQ entry and mention
its advantage compared to socks4a. Reported by David in #2960129.
- Slightly improve the explanation of why filtering may appear
slower than it is.
- Grammar fixes for the ACL section.
- Fixed a link to the 'intercepting' entry and add another one.
- Rename the 'Other' section to 'Mailing Lists' and reword it
to make it clear that nobody is forced to use the trackers
- Note that 'anonymously' posting on the trackers may not always
be possible.
- Suggest to enable debug 32768 when suspecting parsing problems.
- Privoxy-Log-Parser improvements:
- Gather statistics for ressources, methods, and HTTP versions
used by the client.
- Also gather statistics for blocked and redirected requests.
- Provide the percentage of keep-alive offers the client accepted.
- Add a --url-statistics-threshold option.
- Add a --host-statistics-threshold option to also gather
statistics about how many request where made per host.
- Fix a bug in handle_loglevel_header() where a 'scan: ' got lost.
- Add a --shorten-thread-ids option to replace the thread id with
a decimal number.
- Accept and ignore: Looks like we got the last chunk together
with the server headers. We better stop reading.
- Accept and ignore: Continue hack in da house.
- Accept and higlight: Rejecting connection from 10.0.0.2.
Maximum number of connections reached.
- Accept and highlight: Loading actions file: /usr/local/etc/privoxy/default.action
- Accept and highlight: Loading filter file: /usr/local/etc/privoxy/default.filter
- Accept and highlight: Killed all-caps Host header line: HOST: bestproxydb.com
- Accept and highlight: Reducing expected bytes to 0. Marking
the server socket tainted after throwing 4 bytes away.
- Accept: Merged multiple header lines to: 'X-FORWARDED-PROTO: http X-HOST: 127.0.0.1'
- Code cleanups:
- 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.
- Garbage-collect request_contains_null_bytes().
- Ditch redundant code in unload_configfile().
- Ditch LogGetURLUnderCursor() which doesn't seem to be used anywhere.
- In write_socket(), remove the write-only variable write_len in
an ifdef __OS2__ block. Spotted by cppcheck.
- In connect_to(), don't declare the variable 'flags' on OS/2 where
it isn't used. Spotted by cppcheck.
- Limit the scope of various variables. Spotted by cppcheck.
- In add_to_iob(), turn an interestingly looking for loop into a
boring while loop.
- Code cleanup in preparation for external filters.
- In listen_loop(), mention the socket on which we accepted the
connection, not just the source IP address.
- In write_socket(), also log the socket we're writing to.
- In log_error(), assert that escaped characters get logged
completely or not at all.
- In log_error(), assert that ival and sval have reasonable values.
There's no reason not to abort() if they don't.
- Remove an incorrect cgi_error_unknown() call in a
cannot-happen-situation in send_crunch_response().
- Clean up white-space in http_response definition and
move the crunch_reason to the beginning.
- Turn http_response.reason into an enum and rename it
to http_response.crunch_reason.
- Silence a 'gcc (Debian 4.3.2-1.1) 4.3.2' warning on i686 GNU/Linux.
- 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.
- GNUmakefile improvements:
- Use $(SSH) instead of ssh, so one only needs to specify a username once.
- Removed references to the action feedback thingy that hasn't been
working for years.
- Consistently use shell.sourceforge.net instead of shell.sf.net so
one doesn't need to check server fingerprints twice.
- Removed GNUisms in the webserver and webactions targets so they
work with standard tar.
*** 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. Donations
are still welcome too: http://www.privoxy.org/faq/general.html#DONATE
*** Version 3.0.12 ***
- The socket-timeout option now also works on platforms whose
select() implementation modifies the timeout structure.
Previously the timeout was triggered even if the connection
didn't stall. Reported by cyberpatrol.
- The Connection: keep-alive code properly deals with files
larger than 2GB. Previously the connection was closed too
early.
- The content length for files above 2GB is logged correctly.
- The user-manual directive on the show-status page links to
the documentation location specified with the directive,
not to the Privoxy website.
- When running in daemon mode, Privoxy doesn't log anything
to the console unless there are errors before the logfile
has been opened.
- The show-status page prints warnings about invalid directives
on the same line as the directives themselves.
- Fixed several justified (but harmless) compiler warnings,
mostly on 64 bit platforms.
- The mingw32 version explicitly requests the default charset
to prevent display problems with some fonts available on more
recent Windows versions. Patch by Burberry.
- The mingw32 version uses the Privoxy icon in the alt-tab
windows. Patch by Burberry.
- The timestamp and the thread id is omitted in the "Fatal error"
message box on mingw32.
- Fixed two related mingw32-only buffer overflows. Triggering
them required control over the configuration file, therefore
this isn't seen as a security issue.
- In verbose mode, or if the new option --show-skipped-tests
is used, Privoxy-Regression-Test logs skipped tests and the
skip reason.
*** Version 3.0.11 ***
- On most platforms, outgoing connections can be kept alive and
reused if the server supports it. Whether or not this improves
things depends on the connection.
- When dropping privileges, membership in supplementary groups
is given up as well. Not doing that can lead to Privoxy running
with more rights than necessary and violates the principle of
least privilege. Users of the --user option are advised to update.
Thanks to Matthias Drochner for reporting the problem,
providing the initial patch and testing the final version.
- Passing invalid users or groups with the --user option
didn't lead to program exit. Regression introduced in 3.0.7.
- The match all section has been moved from default.action
to a new file called match-all.action. As a result the
default.action no longer needs to be touched by the user
and can be safely overwritten by updates.
- The standard.action file has been removed. Its content
is now part of the default.action file.
- In some situations the logged content length was slightly too low.
- Crunched requests are logged with their own log level.
If you used "debug 1" in the past, you'll probably want
to additionally enable "debug 1024", otherwise only passed
requests will be logged. If you only care about crunched
requests, simply replace "debug 1" with "debug 1024".
- The crunch reason has been moved to the beginning of the
crunch message. For HTTP URLs, the protocol is logged as well.
- Log messages are shortened by printing the thread id on its
own (as opposed to putting it inside the string "Privoxy()").
- The config option socket-timeout has been added to control
the time Privoxy waits for data to arrive on a socket.
- Support for remote toggling is controlled by the configure
option --disable-toggle only. In previous versions it also
depended on the action editor and thus configuring with the
--disable-editor option would disable remote toggling support
as well.
- Requests with invalid HTTP versions are rejected.
- The template symbol @date@ can be used to include a date(1)-like
time string. Initial patch submitted by Endre Szabo.
- Responses from shoutcast servers are accepted again.
Problem reported and fix suggested by Stefan.
- The hide-forwarded-for-headers action has been replaced with
the change-x-forwarded-for{} action which can also be used to
add X-Forwarded-For headers. The latter functionality already
existed in Privoxy versions prior to 3.0.7 but has been removed
as it was often used unintentionally (by not using the
hide-forwarded-for-headers action).
- A "clear log" view option was added to the mingw32 version
to clear out all of the lines in the Privoxy log window.
Based on a patch submitted by T Ford.
- The mingw32 version uses "critical sections" now, which prevents
log message corruption under load. As a side effect, the
"no thread-safe PRNG" warning could be removed as well.
- The mingw32 version's task bar icon is crossed out and
the color changed to gray if Privoxy is toggled off.
*** Version 3.0.10 ***
- Ordinary configuration file changes no longer cause program
termination on OS/2 if the name of the logfile hasn't been
changed as well. This regression probably crept in with the
logging improvements in 3.0.7. Reported by Maynard.
- The img-reorder filter is less likely to mess up JavaScript code in
img tags. Problem and solution reported by Glenn Washburn in #2014552.
- The source tar ball now includes Privoxy-Log-Parser,
a syntax-highlighter for Privoxy logs. For fancy screenshots see:
http://www.fabiankeil.de/sourcecode/privoxy-log-parser/
Documentation is available through perldoc(1).
*** Version 3.0.9 Beta ***
- Added SOCKS5 support (with address resolution done by
the SOCKS5 server). Patch provided by Eric M. Hopper.
- The "blocked" CGI pages include a block reason that was
provided as argument to the last-applying block action.
- If enable-edit-actions is disabled (the default since 3.0.7 beta)
the show-status page hides the edit buttons and explains why.
Previously the user would get the "this feature has been disabled"
message after using the edit button.
- Forbidden CONNECT requests are treated like blocks by default.
The now-pointless treat-forbidden-connects-like-blocks action
has been removed.
- Not enabling limit-connect now allows CONNECT requests to all ports.
In previous versions it would only allow CONNECT requests to port 443.
Use +limit-connect{443} if you think you need the old default behaviour.
- The CGI editor gets turned off after three edit requests with invalid
file modification timestamps. This makes life harder for attackers
who can leverage browser bugs to send fake Referers and intend to
brute-force edit URLs.
- Action settings for multiple patterns in the same section are
shared in memory. As a result these sections take up less space
(and are loaded slightly faster). Problem reported by Franz Schwartau.
- Linear white space in HTTP headers will be normalized to single
spaces before parsing the header's content, headers split across
multiple lines get merged first. This should prevent problems like:
* letting the session-cookies-only action slip
some Cookies through unmodified,
* only suppressing the first line of a header,
thus creating an invalid one, and
* to incorrectly block headers with valid timestamps
that weren't properly recognized.
Headers that could trigger these problems are unlikely to appear
in "normal" web traffic, but could be intentionally generated to
fool some of Privoxy's header parsers.
- Host information is gathered outside the main thread so it's less
likely to delay other incoming connections if the host is misconfigured.
- New config option "hostname" to use a hostname other than
the one returned by the operating system. Useful to speed-up responses
for CGI requests on misconfigured systems. Requested by Max Khon.
- The CGI editor supports the "disable all filters of this type"
directives "-client-header-filter", "-server-header-filter",
"-client-header-tagger" and "-server-header-tagger".
- Fixed false-positives with the link-by-url filter and URLs that
contain the pattern "/jump/".
- The less-download-windows filter no longer messes
"Content-Type: application/x-shockwave-flash" headers up.
- In the show-url-info page's "Final results" section active and
inactive actions are listed separately. Patch provided by Lee.
- The GNUmakefile supports the DESTDIR variable. Patch for
the install target submitted by Radoslaw Zielinski.
- Embedding the content of configuration files in the show-status
page is significantly faster now. For a largish action file (1 MB)
a speedup of about 2450 times has been measured. This is mostly
interesting if you are using large action files or regularly use
Privoxy-Regression-Test while running Privoxy through Valgrind,
for stock configuration files it doesn't really matter.
- If zlib support is unavailable and there are content
filters active but the prevent-compression action is disabled,
the show-url-info page includes a warning that compression
might prevent filtering.
- The show-url-info page provides an OpenSearch Description that
allows to access the page through browser search plugins.
- Custom client-header filters that rewrite the request line
incorrectly no longer cause Privoxy to crash. Reported by din_a4.
- The obsolete kill-popups action has been removed as the
PCRS-based popup filters can do the same and are slightly
less unreliable.
- The inspect-jpegs action has been removed.
- The send-wafer and send-vanilla-wafer actions have been removed.
They weren't particular useful and their behaviour could be emulated
with add-header anyway.
- Privoxy-Regression-Test has been significantly improved.
- Most sections in the default.action file contain tests for
Privoxy-Regression-Test to verify that they are working as intended.
- Parts of Privoxy have been refactored to increase maintainability.
- Building with zlib (if available) is done by default.
*** Version 3.0.8 ***
- Fixed a small memory leak when listen-address only specifies the port.
- The source tar balls now include Privoxy-Regression-Test which
(upon other things) can be used to automatically detect some
packaging problems. Packagers are welcome to give it a try.
- Reverted a change in 3.0.7 that caused path patterns to be checked
even if the host pattern match already failed. While this doesn't
noticeable affect the performance, it makes it less likely to run
out of stack space with overly-complex path patterns the user might
have added.
- Updated the msn, yahoo and google filters to work as advertised again.
- The warning message shown by the show-status CGI page is easier to
understand. Previously it wasn't clear that the error message
is shown below the invalid directive. (Reported by Lee)
- When regenerating Content-Disposition headers the more common
spelling is used for the name. Previously it was written without caps.
- Less confusing log message if the content type isn't overwritten
because force-text-type wasn't used but the old type doesn't look
like content that would be filtered normally.
- Better log messages if the user tries to execute filters that
don't exist.
- Treat the non-standard Request-Range headers like standard range
headers and suppress them if content filtering is enabled.
- Prevent the log messages for CONNECT requests to unacceptable
ports from printing the limit-connect argument as [null] if
limit-connect hasn't been explicitly enabled.
- Don't disable the mingw32 log window if the logfile directive
isn't used. While it was an intentional change in 3.0.7 at least
one user perceived it as a regression and the same effect can
be achieved by disabling all debug directives.
- Fixed two minor problems related to the win32 build process: a css
file was not being in the installer and the trustfile comment in the
config.txt referenced a nonexisting file
- Minor documentation fixes.
*** Version 3.0.7 Beta ***
- Added zlib support to filter content with gzip and deflate
encoding. (Patch provided by Wil Mahan)
- Dedicated filters and actions are used for header filtering.
"filter-client-headers" and "filter-client-headers" are no longer
supported, use server-header-filter{} and client-header-filter{}
instead.
- Tags can be used to change actions based on HTTP headers.
- New server-header filter: less-download-windows.
- New client-header taggers: css-requests, image-requests,
client-ip-address, http-method, allow-post, complete-url,
user-agent and privoxy-control.
- New server-header taggers: content-type and privoxy-control.
- The forward-override{} action allows to change the forwarding
settings through the action files, for example based on client
headers like the User-Agent, or the request origin.
- Socks errors are no longer handled by the CGI page for
DNS resolution failures.
- CGI pages use favicons to signal whether they are error
or control pages. This is useful if you rely heavily on
browser tabs.
- The show-url-info CGI page shows the forwarding settings.
- "Crunch!" log messages (used when Privoxy answers requests
by itself) now also contain the reason.
- Allow to rewrite the request destination behind the client's back.
- Fix socks requests on big-endian platforms. Patch provided by Song Weijia.
- Fixes possible deadlocks and crashes on OpenBSD.
Patch provided by Ralf Horstmann.
- The CGI action editor allows to edit actionfiles with previously
forbidden characters like dots.
- New trust entries are saved with a comment that contains the
trusted referring URL (Suggested by Daniel Griscom).
- Filter descriptions are HTML encoded automatically.
- New config option "split-large-forms" to work
around a browser bug that caused IE6 and IE7 to ignore
the Submit button on the edit-actions-for-url CGI page.
- New config option "allow-cgi-request-crunching" to allow
requests for Privoxy's CGI pages to be blocked, redirected
or (un)trusted like ordinary requests.
- Empty filter files no longer interrupt the filtering process
prematurely and are correctly listed on the show-status CGI page.
- New config option "accept-intercepted-requests" to combine
Privoxy with any packet filter to build an intercepting proxy
for HTTP/1.1 requests (and for HTTP/1.0 requests with Host header set).
- fast-redirects{} catch redirects to https URLs as well.
- redirect{s@foo@bar@} can be used to redirect to a rewritten
version of the original URL.
- Trap unsupported gopher proxy requests.
- Fixed a bug in the User Manual delivery on Windows
(mingw32 only). Images now show up correctly and HTML
pages are no longer padded with garbage data.
- Fixed several minor memory leaks, most of them discovered with Valgrind.
- Only unlink the pidfile if it's actually used.
- Retries after connection problems with forced requests
aren't blocked again.
- On Unix SIGABRT causes a core dump as expected and is no
longer treated as normal shutdown signal.
- The "access denied" CGI page is more descriptive and
allows retries to circumvent the referrer check.
- Updated PCRS to handle unexpected PCRE errors properly.
Fixed crashes that could occur if Privoxy was build
with external PCRE versions newer than Privoxy's internal
one. (Reported by Chung-chieh Shan)
- Fixed crashes with null bytes in PCRS replacement strings
(Patch provided by Felix Gr<47>bert).
- Fixed crashes with header time randomization on mingw32.
- The CGI style sheet is no longer delivered if the referring
page isn't a Privoxy CGI page. This prevents a JavaScript-based
Privoxy detection "attack". Note that detecting Privoxy is
still possible through other ways and Privoxy was never intended
to be invisible anyway.
- Added support for AmigaOS 4, fixed build for AmigaOS 3.x.
- The show-url-info CGI page displays a warning if Privoxy
is currently toggled off.
- The show-status CGI page suppresses the edit button
for action files if Privoxy has no write access.
- Most CGI error pages react properly to HEAD requests.
- Requests with RFC 3253 HTTP methods (used by Subversion)
are accepted. (Patch provided by Petr Kadlec)
- New config option "templdir" to change the location
of the CGI templates to make sure customized templates
aren't "updated".
- Better handling of "HTTP/1.1 100 Continue" responses.
- The background of the PNG pattern is transparent.
- Fixed XML syntax errors caused by banners-by-size and banners-by-url.
- Fixed crashes and possible action file corruptions
when lines containing hashes are written through the CGI editor.
- Supports dynamic filters which can contain variables.
- Supports tags to change the actions based on client or server headers.
- Incorrect actions are logged before program termination.
- The "actionsfile" syntax in the configuration file is consistent
with the rest of the configuration options and requires the
whole file name. This is an incompatible change, if you use
an old configuration file you might have to append ".action"
to your "actionsfile" directives.
- With the configuration file option "enforce-blocks" the
"go there anyway" mechanism can be disabled without recompiling
Privoxy.
- More precise error messages in case of incorrect acl syntax.
- Logs a warning if filtering is enabled but impossible due
to lack of zlib support or use of the prevent-compression action.
- Less noisy handling of Cookie:" and "Connection:" headers.
- Improved error messages in case of connection problems.
- Fix a command-line-parsing bug that was introduced before 3.0.5
beta and caused Privoxy to treat the last argument as configuration
file if no configuration file was specified.
- Treat unknown command line options as fatal errors instead
of silently ignoring them.
- Use string functions with length checks more often.
- Don't log CONNECT requests twice.
- Allow to log the source address for ACL-related connection drops.
- Don't ignore applying filters if the server didn't
specify a Content-Type. Bug reported by Amuro Namie.
- Rejected CONNECT requests are logged with log level info
(enabled by default) and the reason for the block.
- New command line option "--pre-chroot-nslookup hostname" to
intialize the resolver library before chroot'ing. On some systems this
reduces the number of files that must be copied into the chroot tree.
(Patch provided by Stephen Gildea)
- Fix a long-standing memory corruption bug that could cause
Privoxy to overwrite a single byte in memory it didn't explicitly
allocate (but that probably was allocated anyway due to bucket size).
- Send template-based CGI pages as HTTP/1.1 unless the client
asked for HTTP/1.0.
- Let the first line in connection established responses
end in \r\n as required by RFC1945. Reported by Bert van Leeuwen.
- If no log file has been specified, disable logging instead of logging
to stderr.
- Don't block stderr when in daemon mode.
- Ignore missing zero-chunks when filtering chunk-encoded content.
Earlier Privoxy versions would buffer and then forward the content
unmodified which caused some browsers to simply show empty pages.
- Fix double free in cgi_edit_actions_list(). Reported by Venustech AD-LAB.
- The code to add X-Forwarded-For headers when the hide-forwarded-for-headers
action isn't being used has been removed.
- Fixed trustfile feature which previously didn't work without FEATURE_TOGGLE.
Reported by Lee.
- Minor code clean-ups, filter and action file updates.
(Some of them reported by Davide Alberani, Markus Elfring,
Stefan Huehner and Adam Piggott)
*** Version 3.0.6 ***
- New content filters: no-ping, google, msn, yahoo and blogspot.
- New header filters: x-httpd-php-to-html, html-to-xml, xml-to-html
and hide-tor-exit-notation.
- The special header "X-Filter: No" now disables header filtering as well.
- Improved the filters img-reorder, js-annoyances, webbugs,
banners-by-size, banners-by-link and ie-exploits to make them
less likely to break anything.
- Removed outdated URL patterns in default.action and added new ones.
- Added redirection from http://p.p/user-manual to http://p.p/user-manual/
- Changed webinterface default values for hide-user-agent, hide-referrer
and set-image-blocker.
*** Version 3.0.5 Beta ***
- Windows version can be installed/started as a service.
- Windows icon stays blue when Privoxy is idle, green when busy.
- Integrated Fabian Keil's extensive patch. See:
http://www.fabiankeil.de/sourcecode/privoxy/. Includes the
following new or significantly improved actions (among many
other improvements):
content-type-overwrite{}
crunch-client-header{string}
crunch-if-none-match
crunch-server-header{string}
fast-redirects{check-decoded-url}
filter-client-headers
filter-server-headers
force-text-mode
handle-as-empty-document
hide-accept-language{}
hide-content-disposition{}
hide-if-modified-since
hide-referrer{conditional-block}
overwrite-last-modified{}
redirect{URL}
treat-forbidden-connects-like-blocks
- Standard-compliant clients are prevented from displaying cached
copies of Privoxy's error messages after the cause of the problem
has gone.
- Improved DNS error handling.
- Multiple filter files can now be specified in config.
- Added jpeg filtering to defend against MS jpeg vulnerability MS04-028
with the new inspect-jpegs action.
- Removed the "arbitrary" 1000 filter limit - addresses tracker #911950
- Thanks to Jindrich Makovicka for a race condition fix for the log
file. The race condition remains for non-pthread implementations.
Reference patch #1175720. Various other logging enhancements.
- A pile of assorted bug fixes, memory leaks, enhancements, etc.
- Moved Actions file reporting mechanism to SF tracker.
- Two new options for config: enable-remote-http-toggle and
forwarded-connect-retries.
- Trap unsupported FTP requests.
- Let text/xml be filtered.
- Numerous updates to default.action
- Increase the compiled in limit of trusted referrers from 64 to 512
(for trustfile users).
*** Version 3.0.3 ***
- Fixed yet another two memory leaks. Process growth seems stopped now.
- Further tightened security against malicious toggle-off links.
- Excluded text/plain MIME types from filtering. This fixes a
couple of client-crashing, download corruption and
Privoxy performance issues, whose root cause lies in
web servers labelling content of unknown type as text/plain.
- Assorted fixes for POSIX compliance, signal handling, graceful
termination, compiler warnings, OSX support, Win32 systray,
error logging, hostname wildcards, correct detection of NetBSD.
- Workarounds for client (iTunes etc) and server (PHP < 4.2.3) bugs
including the notorious "blank page" problem.
- Various filter improvements; most notably the unsolicited-popups
filter became less destructive
- Major revamp of the actions file
*** Version 3.0.2 ***
- Fixed two memory leaks, one serious
- Fixed bug in pcrs which could cause crashes with user-defined filters
- Fixed bug in domain name matching
- Assorted small fixes (Win32 menu, CGI URL editor, ..)
- Added basic support for the OPTIONS and TRACE http methods
- Added workaround for Bug in Mac OSX that made Privoxy crash occasionally
- Refined the default action file through >400 items of user feedback
- Filter changes:
- Assorted refinements, optimizations and fixes in the js-annoyances,
img-reorder, banners-by-size, banners-by-link, webbugs, refresh-tags,
html-annoyances, content-cookies and fun filters
- Replaced filter "popups" by choice between two modes:

*** Version 2.9.3 pre-Alpha Changes ***
- Amiga support (completely untested by me - I don't have an Amiga)
- "tinygif 3" support (redirects blocked images to a specified URL, so
the browser doesn't have to load and cache many copies of the same
image).
- one case where there were both local and global "referrer" variables
(yuck!) clarified by renaming the local one to "refer".
- Fixed some places where close() was used instead of close_socket().
Thanks to J<>rg Strohmayer (joergs at users.sourceforge.net) for these.
- Temporary hack to get FORCE_LOAD to work with IE. I just lowercased the
FORCE_LOAD_PREFIX. Needs fixing properly.
- Most URLs hardcoded into Junkbuster were changed to go through a script
e.g. http://ijbswa.sourceforge.net/redirect.php?v=2.9.3&to=faq
The only other URLs left are the GNU GPL:
http://www.fsf.org/copyleft/gpl.html
and the home page:
http://ijbswa.sourceforge.net/
... and various URLs which will be intercepted by Junkbuster anyway.
TODO: Still need to do something with the URLs in Junkbuster Corp's
copyright/trademark notice on the bottom of the show-proxy-args page.
- PCRE or GNU Regex is now a #define option.
*** Version 2.9.2 pre-Alpha Changes ***
- Andreas applied the latest version of the FORCE patch.
*** Version 2.9.1 pre-Alpha Changes ***
- in parsers.c, fixed two #ifdef FORCE to #ifdef FORCE_LOAD
(BTW: I think FORCE is precise enough, since loading remote
data is the whole purpose of a proxy..)
- Set the FORCE_PREFIX (back) to 'IJB-FORCE-LOAD-'. While 'noijb.'
is more elegant and looks like a hostname in the URL, it doesn't
make clear to the inexperienced user that the proxy is bypassed. It
also has a higher name collision risk.
- Filled in the function header templates for my functions in
parsers.c (again). They obviously got lost in our current
patch war ;-)
- Cut the credit for the <20>-referrer-option from the config file,
that Stefan had placed there.
- Improved the re_filterfile
*** Version 2.9.0 pre-Alpha Changes ***
- Now use PCRE, not GNU REGEX. I have not yet had chance to check the
syntax of the block/image/cookie file to ensure that they match what
is expected - however they seem to work.
- Replaced "configure" script with one generated by "autoconf". Also
use a header "config.h" (was ijbconfig.h in my previous release) for
the #defines. "config.h" is now generated with "autoheader" from
"acconfig.h" and "configure.in". (Note that to install you do not
need autoconf or autoheader - just run "./configure".)
To see command-line options, run "./configure --help".
This is my first ever autoconf script, so it has some rough edges
(how PCRE is handled is the roughest).
- Error logging code replaced with new module errlog.c, based on the
one from JunkbusterMT (but with the threading code removed).
- Most of Rodney's 0.21 and 0.21A patches applied. (Marked *). I did not
apply all of these, since I had already independently done conditional
popup file, conditional image file, and integration of popup code.
- ACL, Jar and trust files conditionally compiled.
- New source file headers.
- Various cosmetic changes. (But I have not consistently ordered the
config files - I think that's worthwhile, but it's 1am and I want to
get this released!)
- RCS tags on .h files.
- RCS tags are const char[] rather than const char *. (Saves 4 bytes
per tag ;-)
- VC++ project files renamed to vc_junkbuster.*.
- show-proxy-args now shows status of all conditionals, not just REGEX
- Various functions moved around. Most notably all the system-specific
sockets code which was spread between jcc.c, bind.c, and connect.c,
has been moved to "jbsockets.c". The non-system-specific code from
connect.c and socks4.c has been movet to "gateway.c". Also, the
config file loader and the global variables it writes to have been
moved to "loadcfg.c". (Maybe this should go into loaders.c?)
And candidate for the "worst filename ever" award is "miscutil.c",
which contains, well, miscellaneous utility functions like zalloc.
(Suggestions for a better name for this file are welcome!)
- Loaders now use a common function to read a line and skip comments,
and this function also stores the proxy_args.
- Added ./junkbuster --help (Not for Win32 GUI)
- Added ./junkbuster --version (Not for Win32 GUI)
- Win32 resources are now all marked as "U.S. English", rather than
being a mix of "U.S. English", "U.K. English" and "Irish English".
- Version number changes to 2.9.0
