4 *** Version 3.0.27 stable ***
6 - General improvements:
7 - Add a receive-buffer-size directive which can be used to
8 set the size of the previously statically allocated buffer
9 in handle_established_connection().
10 Increasing the buffer size increases Privoxy's memory usage but
11 can lower the number of context switches and thereby reduce the
12 CPU usage and potentially increase the throughput.
13 This is mostly relevant for fast network connections and
14 large downloads that don't require filtering.

16 - Add a listen-backlog directive which specifies the backlog
17 value passed to listen().
18 Sponsored by: Robert Klemme
19 - Add an enable-accept-filter directive which allows to
20 toggle accept filter support at run time when compiled
21 with FEATURE_ACCEPT_FILTER support.
22 It makes testing more convenient and now that it's
23 optional we can emit an error message if enabling
24 the accept filter fails.
25 Sponsored by: Robert Klemme
26 - Add a delay-response{} action.
27 This is useful to tar pit JavaScript requests that
28 are endlessly retried in case of blocks. It can also
29 be used to simulate a slow Internet connection.
30 Sponsored by: Robert Klemme
31 - Add a 'trusted-cgi-referrer' directive.
32 It allows to configure another page or site that can be used
33 to reach sensitive CGI resources.
34 Sponsored by: Robert Klemme
35 - Add a --fuzz mode which exposes Privoxy internals to input
37 Mainly tested with American Fuzzy Lop. For details see:
38 https://www.fabiankeil.de/talks/fuzzing-on-freebsd/
39 This work was partially funded with donations and done
40 as part of the Privoxy month in 2015.
41 - Consistently use the U(ngreedy) flag in the 'img-reorder' filter.
42 - listen_loop(): Reuse a single thread attribute object
43 The object doesn't change and creating a new one for
44 every thread is a waste of (CPU) time.
45 Sponsored by: Robert Klemme
46 - Free csp resources in the thread that belongs to the csp instead
47 of the main thread which has enough on its plate already.
48 Sponsored by: Robert Klemme
49 - Improve 'socket timeout reached' message.
50 Log the timeout that was triggered and downgrade the
51 log level to LOG_LEVEL_CONNECT to reduce the log noise
52 with common debug settings.
53 The timeout isn't necessary the result of an error and
54 usually merely indicates that Privoxy's socket timeout
55 is lower than the relevant timeouts used by client and
57 Sponsored by: Robert Klemme
58 - Explicitly taint the server socket in case of CONNECT requests.
59 This doesn't fix any known problems, but makes
60 some log messages less confusing.
61 - Let write_pid_file() terminate if the pid file can't be opened.
62 Logging the issue at info level is unlikely to help.
63 - log_error(): Reduce the mutex-protected area by not using a
64 heap-allocated buffer that is shared between all threads.
65 This increases performance and reduces the latency with
66 verbose debug settings and multiple concurrent connections.
67 Sponsored by: Robert Klemme
68 - Let zalloc() use calloc() if it's available.
69 In some situations using calloc() can be faster than
70 malloc() + memset() and it should never be slower.
71 In the real world the impact of this change is not
72 expected to be noticeable.
73 Sponsored by: Robert Klemme
74 - Never use select() when poll() is available.
75 On most platforms select() is limited by FD_SETSIZE while
76 poll() is not. This was a scaling issue for multi-user setups.
77 Using poll() has no downside other than the usual risk
78 that code modifications may introduce new bugs that have
79 yet to be found and fixed.
80 At least in theory this commit could also reduce the latency
81 when there are lots of connections and select() would use
82 "bit fields in arrays of integers" to store file descriptors.
83 Another side effect is that Privoxy no longer has to stop
84 monitoring the client sockets when pipelined requests are
85 waiting but can't be read yet.
86 This code keeps the select()-based code behind ifdefs for
87 now but hopefully it can be removed soonish to make the

90 - Add a 'reproducible-tarball-dist' target.
91 It's currently separate from the "tarball-dist" target
92 because it requires a tar implementation with mtree spec
94 It's far from being perfect and does not enforce a
95 reproducible mode, but it's better than nothing.
96 - Use arc4random() if it's available.
97 While Privoxy doesn't need high quality pseudo-random numbers
98 there's no reason not to use them when we can and this silences
99 a warning emitted by code checkers that can't tell whether or not
101 - Show the FEATURE_EXTERNAL_FILTERS status on the status page.
102 Better late than never. Previously a couple of tests weren't
103 executed as Privoxy-Regression-Test couldn't detect that the
104 FEATURE_EXTERNAL_FILTERS dependency was satisfied.
105 - Ditch FEATURE_IMAGE_DETECT_MSIE.
106 It's an obsolete workaround we inherited from Junkbuster
107 and was already disabled by default.
108 Users that feel the urge to work around issues with
109 image requests coming from an Internet Explorer version
110 from more than 15 years ago can still do this using tags.
111 - Consistently use strdup_or_die() instead of strdup() in
112 cases where allocation failures aren't expected.
113 Using strdup_or_die() allows to remove a couple of explicit
114 error checks which slightly reduces the size of the binary.
115 - Insert a refresh tag into the /client-tags CGI page when
116 serving it while a client-specific tag is temporarily enabled.
117 This makes it less likely that the user ends up
118 looking at tag state that is out of date.
119 - Use absolute URLs in the client-tag forms.
120 It's more consistent with the rest of the CGI page
121 URLs and makes it more convenient to copy the forms
123 - cgi_error_disabled(): Use status code 403 and an appropriate response line
124 - Use a dedicated CGI handler to deal with tag-toggle requests
125 As a result the /client-tags page is now safe to reach without
126 trusted Referer header which makes bookmarking or linking to
128 Finally, refreshing the /client-tags page to show the
129 current state can no longer unintentionally repeat the
130 previous toggle request.
131 - Don't add a "Connection" header for CONNECT requests.
132 Explicitly sending "Connection: close" is not necessary and
133 apparently it causes problems with some forwarding proxies
134 that will close the connection prematurely.
135 Reported by Marc Thomas.
136 - Fix compiler warnings.
139 - rfc2553_connect_to(): Properly detect and log when poll()
140 reached the time out. Previously this was logged as:
141 Could not connect to [...]: No error: 0.
142 which isn't very helpful.
143 Sponsored by: Robert Klemme
144 - add_tag_for_client(): Set time_to_live properly.
145 Previously the time_to_live was always set for the first tag.
146 Attempts to temporarily enable a tag would result in enabling
147 it permanently unless no tag was enabled already.
148 - Revert r1.165 which didn't perform as advertised.
149 While the idea was to use "https:// when creating links
150 for the user manual on the website", the actual effect
151 was to use "https://" when Privoxy was supposed to serve
152 the user manual itself.
153 Reported by Yossi Zahn on Privoxy-devel@.
154 - socks5_connect(): Fail in case of unsupported address types.
155 Previously they would not be detected right away and
156 Privoxy would fail later on with an error message that
157 didn't make it obvious that the problem was socks-related.
158 So far, no such problems have actually been reported.
159 - socks5_connect(): Properly deal with socks replies that
160 contain IPv6 addresses.
161 Previously parts of the reply were left unread and
162 later on treated as invalid HTTP response data.
163 Fixes #904 reported by Danny Goossen who also provided
164 the initial version of this patch.
166 - Action file improvements:
167 - Unblock 'msdn.microsoft.com/'.
168 It (presumably) isn't used to serve the kind of ads Privoxy should
169 block by default but happens to serve lots of pages with URLs that
170 are likely to result in false positives.
171 Reported by bugreporter1694 in AF#939.
172 - Disable gif deanimation for requests tagged with CSS-REQUEST.
173 The action will ignore content that isn't considered text
174 anyway and explicitly disabling it makes this more obvious
175 if "action" debugging (debug 65536) is enabled while
176 "gif deanimation" debugging (debug 256) isn't.
177 - Explicitly disable HTML filters for requests with CSS-REQUEST tag.
178 The filters are unlikely to break CSS files but executing
179 them without (intentionally) getting any hits is a waste of
180 cpu time and makes the log more noisy when running with
182 - Unblock 'adventofcode.com/'.
183 Reported by Clint Adams in Debian bug #848211.
184 Fixes Roland's AF#937.
185 - Unblock 'adlibris.com'.
186 Reported by Wyrex in #935
187 - Unblock .golang.org/
188 - Add fast-redirects exception for '.youtube.com/.*origin=http'
190 - Privoxy-Log-Parser:
191 - Don't gather host and resource statistics if they aren't requested.
192 While the performance impact seems negligible this significantly
193 reduces the memory usage if there are lots of requests.
194 - Bump version as the behaviour (slightly) changed.
195 - Count connection failures as well in statistics mode.
196 Sponsored by: Robert Klemme
197 - Count connection timeouts as well in statistics mode.
198 Sponsored by: Robert Klemme
199 - Fix an 'uninitialized value' warning when generating
200 statistics for a log file without response headers.
201 While privoxy-log-parser was supposed to detect this already,
202 the check was flawed and the message the user didn't see was
203 somewhat confusing anyway.
204 Now the message is less confusing, more helpful and actually printed.
205 Reported by: Robert Klemme
207 - Documentation improvements:
208 - Refer to the git sources instead of CVS.
209 - Use GNU/Linux when referring to the OS instead of the kernel.
210 - Add FAQ entry for what to do if editing the config file is access denied.
211 - Add brief HTTP/2 FAQ.
212 - Add a small fuzzing section to the developer documentation.
213 - Add a client-header-tagger{client-ip-address} example.
214 - Stop suggesting that Privoxy is an anonymizing proxy.
215 The term could lead to Privoxy users overestimating
216 what it can do on its own (without Tor).
217 - Make it more obvious that SPI accepts Paypal, too.
218 Currently most donations are made through the Paypal account
219 managed by Zwiebelfreunde e.V. and a more even distribution
221 - Suggest to log applying actions as well when reproducing problems.
222 - Explicitly mention that Privoxy binaries are built by individuals
223 on their own systems. Buyer beware!
224 - Mention the release feed on the homepage.
225 - Remove a mysterious comment with a GNU FDL link as it isn't
226 useful and could confuse license scanners.
227 In May 2002 it was briefly claimed that "this document" was covered
228 by the GNU FDL. The commit message (r1.5) doesn't explain the motivation
229 or whether all copyright holders were actually asked and agreed to the
230 declared license change.
231 It's thus hard to tell whether or not the license change was legit,
232 but luckily two days later the "doc license" was "put" "back to GPL"
234 At the same time the offending comment with a link to the FDL
235 (not the GPL) was added for no obvious reason.
239 - Bump for-privoxy-version to 3.0.27 as we now rely on untrusted
240 CGI request being rejected with status code 403 (instead of 200).
241 - Update test for /send-stylesheet and add another one
244 - Consistently use https:// when linking to the Privoxy website.
245 - Remove SourceForge references in Copyright header.
246 - Remove a couple of SourceForge references in a comment.
247 While at it, fix the grammar.
248 - Move the site-specific documentation block before the generic one.
249 While most Privoxy installations don't have a site-specific
250 documentation block, in cases were it exists it's likely to
251 be more relevant than the generic one.
252 Showing it first makes it less likely that users stop reading
253 before they reach it, especially on pages that don't fit on
256 - Build system improvements:
257 - Prefer openjade to jade. On some systems Jade produces
258 HTML with unescaped ampersands in URLs.
259 - Prefer OpenSP to SP to be consistent.
260 - Have Docbook generated HTML files be straight ASCII.
261 Dealing with a mixture of ISO-8859 and UTF-8 files is problematic.
262 - Echo the filename to stderr for 'make dok-tidy'.
263 Make it a bit easier to find errors in docbook generated HTML.
264 - Warn when still using select().
265 - Warn when compiling without calloc().
266 - Make it more obvious that the --with-fdsetsize configure switch
267 is pointless if poll() is available.
268 - Remove support for AmigaOS.
269 - Update windows build system to use supported software.
270 The cygwin gcc -mno-cygwin option is no longer supported, so
271 convert the windows build system to use the cygwin cross-compiler
272 to build "native" code.
273 - Add --enable-static-linking option for configure
274 does the same thing as LDFLAGS=-static; ./configure
275 but nicer than mixing evars and configure options.
277 *** Version 3.0.26 stable ***
280 - Fixed crashes with "listen-addr :8118" (SF Bug #902).
281 The regression was introduced in 3.0.25 beta and reported
282 by Marvin Renich in Debian bug #834941.
284 - General improvements:
285 - Log when privoxy is toggled on or off via cgi interface.
286 - Highlight the "Info: Now toggled " on/off log message
287 in the Windows log viewer.
288 - Highlight the loading actions/filter file log message
289 in the Windows log viewer.
290 - Mention client-specific tags on the toggle page as a
291 potentionally more appropriate alternative.
293 - Documentation improvements:
294 - Update download section on the homepage.
295 The downloads are available from the website now.
297 - Remove obsolete reference to mailing lists hosted at SourceForge.
298 - Update the "Before the Release" section of the developer manual.
300 - Infrastructure improvements:
301 - Add perl script to generate an RSS feed for the packages
302 Submitted by "Unknown".
304 - Build system improvements:
305 - strptime.h: fix a compiler warning about ambiguous else.
306 - configure.in: Check for Docbook goo on the BSDs as well.
307 - GNUMakefile.in: Let the dok-user target remove temporary files.
309 *** Version 3.0.25 beta ***
312 - Always use the current toggle state for new requests.
313 Previously new requests on reused connections inherited
314 the toggle state from the previous request even though
315 the toggle state could have changed.
316 Reported by Robert Klemme.
317 - Fixed two buffer-overflows in the (deprecated) static
318 pcre code. These bugs are not considered security issues
319 as the input is trusted.
320 Found with afl-fuzz and ASAN.
322 - General improvements:
323 - Added support for client-specific tags which allow Privoxy
324 admins to pre-define tags that are set for all requests from
325 clients that previously opted in through the CGI interface.
326 They are useful in multi-user setups where admins may
327 want to allow users to disable certain actions and filters
328 for themselves without affecting others.
329 In single-user setups they are useful to allow more fine-grained
330 toggling. For example to disable request blocking while still
331 crunching cookies, or to disable experimental filters only.
332 This is an experimental feature, the syntax and behaviour may
333 change in future versions.
334 Sponsored by Robert Klemme.
335 - Dynamic filters and taggers now support a $listen-address variable
336 which contains the address the request came in on.
337 For external filters the variable is called $PRIVOXY_LISTEN_ADDRESS.
338 Original patch contributed by pursievro.
339 - Add client-header-tagger 'listen-address'.
340 - Include the listen-address in the log message when logging new requests.
341 Patch contributed by pursievro.
342 - Turn invalid max-client-connections values into fatal errors.
343 - The show-status page now shows whether or not dates before 1970
344 and after 2038 are expected to be handled properly.
345 This is mainly useful for Privoxy-Regression-Test but could
346 also come handy when dealing with time-related support requests.
347 - On Mac OS X the thread id in log messages are more likely to
349 - When complaining about missing filters, the filter type is logged
351 - A couple of harmless coverity warnings were silenced
352 (CID #161202, CID #161203, CID #161211).
354 - Action file improvements:
355 - Filtering is disabled for Range requests to let download resumption
356 and Windows updates work with the default configuration.
357 - Unblock ".ardmediathek.de/".
358 Reported by ThTomate in #932.
360 - Documentation improvements:
361 - Add FAQ entry for crashes caused by memory limits.
362 - Remove obsolete FAQ entry about a bug in PHP 4.2.3.
363 - Mention the new mailing lists were appropriate.
364 As the archives have not been migrated, continue to
365 mention the archives at SF in the contacting section
367 - Note that the templates should be adjusted if Privoxy is
368 running as intercepting proxy without getting all requests.
369 - A bunch of links were converted to https://.
370 - Rephrase onion service paragraph to make it more obvious
371 that Tor is involved and that the whole website (and not
372 just the homepage) is available as onion service.
373 - Streamline the "More information" section on the homepage further
374 by additionally ditching the link to the 'See also' section
375 of the user manual. The section contains mostly links that are
376 directly reachable from the homepage already and the rest is
377 not significant enough to get a link from the homepage.
378 - Change the add-header{} example to set the DNT header
379 and use a complete section to make copy and pasting
381 Add a comment to make it obvious that adding the
382 header is not recommended for obvious reasons.
383 Using the DNT header as example was suggested by
385 - Streamline the support-and-service template
386 Instead of linking to the various support trackers
387 (whose URLs hopefully change soon), link to the
388 contact section of the user manual to increase the
389 chances that users actually read it.
390 - Add a FAQ entry for tainted sockets.
391 - More sections in the documentation have stable URLs now.
392 - FAQ: Explain why 'ping config.privoxy.org' is not expected
393 to reach a local Privoxy installation.
394 - Note that donations done through Zwiebelfreunde e.V. currently
395 can't be checked automatically.
396 - Updated section regarding starting Privoxy under OS X.
397 - Use dedicated start instructions for FreeBSD and ElectroBSD.
398 - Removed release instructions for AIX. They haven't been working
399 for years and unsurprisingly nobody seems to care.
400 - Removed obsolete reference to the solaris-dist target.
401 - Updated the release instructions for FreeBSD.
402 - Removed unfinished release instructions for Amiga OS and HP-UX 11.
403 - Added a pointer to the Cygwin Time Machine for getting the last release of
404 Cygwin version 1.5 to use for building Privoxy on Windows.
405 - Various typos have been fixed.
407 - Infrastructure improvements:
408 - The website is no longer hosted at SourceForge and
409 can be reached through https now.
410 - The mailing lists at SourceForge have been deprecated,
411 you can subscribe to the new ones at: https://lists.privoxy.org/
412 - Migrating the remaining services from SourceForge is
413 work in progress (TODO list item #53).
415 - Build system improvements:
416 - Add configure argument to optimistically redefine FD_SETSIZE
417 with the intent to change the maximum number of client
418 connections Privoxy can handle. Only works with some libcs.
419 Sponsored by Robert Klemme.
420 - Let the tarball-dist target skip files in ".git".
421 - Let the tarball-dist target work in cwds other than current.
422 - Make the 'clean' target faster when run from a git repository.
423 - Include tools in the generic distribution.
424 - Let the gen-dist target work in cwds other than current.
425 - Sort find output that is used for distribution tarballs
426 to get reproducible results.
427 - Don't add '-src' to the name of the tar ball generated by the
428 gen-dist target. The package isn't a source distribution but a
430 While at it, use a variable for the name to reduce the chances
431 that the various references get out of sync and fix the gen-upload
432 target which was looking in the wrong directory.
433 - Add regression-tests.action to the files that are distributed.
434 - The gen-dist target which was broken since 2002 (r1.92) has been fixed.
435 - Remove genclspec.sh which has been obsolete since 2009.
436 - Remove obsolete reference to Redhat spec file.
437 - Remove the obsolete announce target which has been commented out years ago.
438 - Let rsync skip files if the checksums match.
440 - Privoxy-Regression-Test:
441 - Add a "Default level offset" directive which can be used to
442 change the default level by a given value.
443 This directive affects all tests located after it until the end
444 of the file or a another "Default level offset" directive is reached.
445 The purpose of this directive is to make it more convenient to skip
446 similar tests in a given file without having to remove or disable
447 the tests completely.
448 - Let test level 17 depend on FEATURE_64_BIT_TIME_T
449 instead of FEATURE_PTHREAD which has no direct connection
451 - Fix indentation in perldoc examples.
452 - Don't overlook directives in the first line of the action file.
453 - Bump version to 0.7.
454 - Fix detection of the Privoxy version now that https://
455 is used for the website.
457 *** Version 3.0.24 stable ***
459 - Security fixes (denial of service):
460 - Prevent invalid reads in case of corrupt chunk-encoded content.
461 CVE-2016-1982. Bug discovered with afl-fuzz and AddressSanitizer.
462 - Remove empty Host headers in client requests.
463 Previously they would result in invalid reads. CVE-2016-1983.
464 Bug discovered with afl-fuzz and AddressSanitizer.
467 - When using socks5t, send the request body optimistically as well.
468 Previously the request body wasn't guaranteed to be sent at all
469 and the error message incorrectly blamed the server.
470 Fixes #1686 reported by Peter Müller and G4JC.
471 - Fixed buffer scaling in execute_external_filter() that could lead
472 to crashes. Submitted by Yang Xia in #892.
473 - Fixed crashes when executing external filters on platforms like
474 Mac OS X. Reported by Jonathan McKenzie on ijbswa-users@.
475 - Properly parse ACL directives with ports when compiled with HAVE_RFC2553.
476 Previously the port wasn't removed from the host and in case of
477 'permit-access 127.0.0.1 example.org:80' Privoxy would try (and fail)
478 to resolve "example.org:80" instead of example.org.
479 Reported by Pak Chan on ijbswa-users@.
480 - Check requests more carefully before serving them forcefully
481 when blocks aren't enforced. Privoxy always adds the force token
482 at the beginning of the path, but would previously accept it anywhere
483 in the request line. This could result in requests being served that
484 should be blocked. For example in case of pages that were loaded with
485 force and contained JavaScript to create additionally requests that
486 embed the origin URL (thus inheriting the force prefix).
487 The bug is not considered a security issue and the fix does not make
488 it harder for remote sites to intentionally circumvent blocks if
489 Privoxy isn't configured to enforce them.
490 Fixes #1695 reported by Korda.
491 - Normalize the request line in intercepted requests to make rewriting
492 the destination more convenient. Previously rewrites for intercepted
493 requests were expected to fail unless $hostport was being used, but
494 they failed "the wrong way" and would result in an out-of-memory
495 message (vanilla host patterns) or a crash (extended host patterns).
496 Reported by "Guybrush Threepwood" in #1694.
497 - Enable socket lingering for the correct socket.
498 Previously it was repeatedly enabled for the listen socket
499 instead of for the accepted socket. The bug was found by
500 code inspection and did not cause any (reported) issues.
501 - Detect and reject parameters for parameter-less actions.
502 Previously they were silently ignored.
503 - Fixed invalid reads in internal and outdated pcre code.
504 Found with afl-fuzz and AddressSanitizer.
505 - Prevent invalid read when loading invalid action files.
506 Found with afl-fuzz and AddressSanitizer.
507 - Windows build: Use the correct function to close the event handle.
508 It's unclear if this bug had a negative impact on Privoxy's behaviour.
509 Reported by Jarry Xu in #891.
510 - In case of invalid forward-socks5(t) directives, use the
511 correct directive name in the error messages. Previously they
512 referred to forward-socks4t failures.
513 Reported by Joel Verhagen in #889.
515 - General improvements:
516 - Set NO_DELAY flag for the accepting socket. This significantly reduces
517 the latency if the operating system is not configured to set the flag
518 by default. Reported by Johan Sintorn in #894.
519 - Allow to build with mingw x86_64. Submitted by Rustam Abdullaev in #135.
520 - Introduce the new forwarding type 'forward-webserver'.
521 Currently it is only supported by the forward-override{} action and
522 there's no config directive with the same name. The forwarding type
523 is similar to 'forward', but the request line only contains the path
524 instead of the complete URL.
525 - The CGI editor no longer treats 'standard.action' special.
526 Nowadays the official "standards" are part of default.action
527 and there's no obvious reason to disallow editing them through
528 the cgi editor anyway (if the user decided that the lack of
529 authentication isn't an issue in her environment).
530 - Improved error messages when rejecting intercepted requests
531 with unknown destination.
532 - A couple of log messages now include the number of active threads.
533 - Removed non-standard Proxy-Agent headers in HTTP snipplets
534 to make testing more convenient.
535 - Include the error code for pcre errors Privoxy does not recognize.
536 - Config directives with numerical arguments are checked more carefully.
537 - Privoxy's malloc() wrapper has been changed to prevent zero-size
538 allocations which should only occur as the result of bugs.
539 - Various cosmetic changes.
541 - Action file improvements:
542 - Unblock ".deutschlandradiokultur.de/".
543 Reported by u302320 in #924.
544 - Add two fast-redirect exceptions for "yandex.ru".
545 - Disable filter{banners-by-size} for ".plasmaservice.de/".
546 - Unblock "klikki.fi/adv/".
547 - Block requests for "resources.infolinks.com/".
548 Reported by "Black Rider" on ijbswa-users@.
549 - Block a bunch of criteo domains.
550 Reported by Black Rider.
551 - Block "abs.proxistore.com/abe/".
552 Reported by Black Rider.
553 - Disable filter{banners-by-size} for ".black-mosquito.org/".
554 - Disable fast-redirects for "disqus.com/".
556 - Documentation improvements:
557 - FAQ: Explicitly point fingers at ASUS as an example of a
558 company that has been reported to force malware based on
559 Privoxy upon its customers.
560 - Correctly document the action type for a bunch of "multi-value"
561 actions that were incorrectly documented to be "parameterized".
562 Reported by Gregory Seidman on ijbswa-users@.
563 - Fixed the documented type of the forward-override{} action
564 which is obviously 'parameterized'.
566 - Website improvements:
567 - Users who don't trust binaries served by SourceForge
568 can get them from a mirror. Migrating away from SourceForge
569 is planned for 2016 (TODO list item #53).
570 - The website is now available as onion service
571 (http://jvauzb4sb3bwlsnc.onion/).
573 *** Version 3.0.23 stable ***
576 - Fixed a DoS issue in case of client requests with incorrect
577 chunk-encoded body. When compiled with assertions enabled
578 (the default) they could previously cause Privoxy to abort().
579 Reported by Matthew Daley. CVE-2015-1380.
580 - Fixed multiple segmentation faults and memory leaks in the
581 pcrs code. This fix also increases the chances that an invalid
582 pcrs command is rejected as such. Previously some invalid commands
583 would be loaded without error. Note that Privoxy's pcrs sources
584 (action and filter files) are considered trustworthy input and
585 should not be writable by untrusted third-parties. CVE-2015-1381.
586 - Fixed an 'invalid read' bug which could at least theoretically
587 cause Privoxy to crash. So far, no crashes have been observed.
589 - Compiles with --disable-force again. Reported by Kai Raven.
590 - Client requests with body that can't be delivered no longer
591 cause pipelined requests behind them to be rejected as invalid.
592 Reported by Basil Hussain.
594 - General improvements:
595 - If a pcrs command is rejected as invalid, Privoxy now logs
596 the cause of the problem as text. Previously the pcrs error
598 - The tests are less likely to cause false positives.
600 - Action file improvements:
601 - '.sify.com/' is no longer blocked. Apparently it is not actually
602 a pure tracking site (anymore?). Reported by Andrew on ijbswa-users@.
603 - Unblock banners on .amnesty.de/ which aren't ads.
605 - Documentation improvements:
606 - The 'Would you like to donate?' section now also contains
608 - The list of supported operating systems has been updated.
609 - The existence of the SF support and feature trackers has been
610 deemphasized because they have been broken for months.
611 Most of the time the mailing lists still work.
612 - The claim that default.action updates are sometimes released
613 on their own has been removed. It hasn't happened in years.
614 - Explicitly mention that Tor's port may deviate from the default
615 when using a bundle. Requested by Andrew on ijbswa-users@.
617 *** Version 3.0.22 stable ***
620 - Fixed a memory leak when rejecting client connections due to
621 the socket limit being reached (CID 66382). This affected
622 Privoxy 3.0.21 when compiled with IPv6 support (on most
623 platforms this is the default). CVE-2015-1030.
624 - Fixed an immediate-use-after-free bug (CID 66394) and two
625 additional unconfirmed use-after-free complaints made by
626 Coverity scan (CID 66391, CID 66376). CVE-2015-1031.
627 - Actually show the FORCE_PREFIX value on the show-status page.
628 - Properly deal with Keep-Alive headers with timeout= parameters
629 If the timeout still can't be parsed, use the configured
630 timeout instead of preventing the client from keeping the
631 connection alive. Fixes #3615312/#870 reported by Bernard Guillot.
632 - Not using any filter files no longer results in warning messages
633 unless an action file is referencing header taggers or filters.
634 Reported by Stefan Kurtz in #3614835.
635 - Fixed a bug that prevented Privoxy from reusing some reusable
636 connections. Two bit masks with different purpose unintentionally
638 - A couple of additional bugs were discovered by Coverity Scan.
639 The fixes that are not expected to affect users are not explicitly
640 mentioned here, for details please have a look at the CVS logs.
642 - General improvements:
643 - Introduced negative tag patterns NO-REQUEST-TAG and NO-RESPONSE-TAG.
644 They apply if no matching tag is found after parsing client or
646 - Add support for external filters which allow to process the
647 response body with a script or program written in any language
648 the platform supports. External filters are enabled with
649 +external-filter{} after they have been defined in one of the
650 filter files with a header line starting with "EXTERNAL-FILTER:".
651 External filter support is experimental, not compiled by default
652 and known not to work on all platforms.
653 - Add support for the 'PATCH' method as defined in RFC5789.
654 - Reject requests with unsupported Expect header values.
655 Fixes a couple of Co-Advisor tests.
656 - Normalize the HTTP-version in forwarded requests and responses.
657 This is an explicit RFC 2616 MUST and RFC 7230 mandates that
658 intermediaries send their own HTTP-version in forwarded
660 - Server 'Keep-Alive' headers are no longer forwarded. From a user's
661 point of view it doesn't really matter, but RFC 2616 (obsolete)
662 mandates that the header is removed and this fixes a Co-Advisor
664 - Change declared template file encoding to UTF-8. The templates
665 already used a subset of UTF-8 anyway and changing the declaration
666 allows to properly display UTF-8 characters used in the action files.
667 This change may require existing action files with ISO-8859-1
668 characters that aren't valid UTF-8 to be converted to UTF-8.
669 Requested by Sam Chen in #582.
670 - Do not pass rejected keep-alive timeouts to the server. It might
671 not have caused any problems (we know of), but doing the right
672 thing shouldn't hurt either.
673 - Let log_error() use its own buffer size #define to make changing
674 the log buffer size slightly less inconvenient.
675 - Turned single-threaded into a "proper" toggle directive with arguments.
676 - CGI templates no longer enforce new windows for some links.
677 - Remove an undocumented workaround ('HOST' header removal) for
678 an Apple iTunes bug that according to #729900 got fixed in 2003.
680 - Action file improvements:
681 - The pattern 'promotions.' is no longer being blocked.
682 Reported by rakista in #3608540.
683 - Disable fast-redirects for .microsofttranslator.com/.
684 - Disable filter{banners-by-size} for .dgb-tagungszentren.de/.
685 - Add adn.speedtest.net as a site-specific unblocker.
686 Support request #3612908.
687 - Disable filter{banners-by-size} for creativecommons.org/.
688 - Block requests to data.gosquared.com/. Reported by cbug in #3613653.
689 - Unblock .conrad./newsletter/. Reported by David Bo in #3614238.
690 - Unblock .bundestag.de/.
691 - Unblock .rote-hilfe.de/.
692 - Disable fast-redirects for .facebook.com/plugins/like.php.
693 - Unblock Stackexchange popup URLs that aren't used to serve ads.
694 Reported by David Wagner in #3615179.
695 - Disable fast-redirects for creativecommons.org/.
696 - Unblock .stopwatchingus.info/.
697 - Block requests for .adcash.com/script/.
698 Reported by Tyrexionibus in #3615289.
699 - Disable HTML filters if the response was tagged as JavaScript.
700 Filtering JavaScript code with filters intended to deal with HTML
701 is usually a waste of time and, more importantly, may break stuff.
702 - Use a custom redirect{} for .washingtonpost.com/wp-apps/imrs\.php\?src=
703 Previously enabling the 'Advanced' settings (or manually enabling
704 +fast-redirects{}) prevented some images from being loaded properly.
705 - Unblock "adina*." Fixes #919 reported by Morton A. Goldberg.
707 - Unblock 'adele*.'. Reported by Adele Lime in #1663.
708 - Disable banners-by-size for kggp.de/.
710 - Filter file improvements & bug fixes:
711 - Decrease the chances that js-annoyances creates invalid JavaScript.
712 Submitted by John McGowan on ijbswa-users@.
713 - Let the msn filter hide 'related' ads again.
714 - Remove a stray '1' in the 'html-annoyances' filter.
715 - Prevent img-reorder from messing up img tags with empty src
716 attributes. Fixes #880 reported by Duncan.
718 - Documentation improvements:
719 - Updated the 'Would you like to donate?' section.
720 - Note that invalid forward-override{} parameter syntax isn't
721 detected until the parameter is used.
722 - Add another +redirect{} example: a shortcut for illumos bugs.
723 - Make it more obvious that many operating systems support log
724 rotation out of the box.
725 - Fixed dead links. Reported by Mark Nelson in #3614557.
726 - Rephrased the 'Why is the configuration so complicated?' answer
727 to be slightly less condescending. Anonymously suggested in #3615122.
728 - Be more explicit about accept-intercepted-requests's lack of MITM support.
729 - Make 'demoronizer' FAQ entries more generic.
730 - Add an example hostname to the --pre-chroot-nslookup description.
731 - Add an example for a host pattern that matches an IP address.
732 - Rename the 'domain pattern' to 'host pattern' as it may
733 contain IP addresses as well.
734 - Recommend forward-socks5t when using Tor. It seems to work fine and
735 modifying the Tor configuration to profit from it hasn't been necessary
737 - Add another redirect{} example to stress that redirect loops can
738 and should be avoided.
739 - The usual spelling and grammar fixes. Parts of them were
740 reported by Reuben Thomas in #3615276.
741 - Mention the PCRS option letters T and D in the filter section.
742 - Clarify that handle-as-empty-doc-returns-ok is still useful
743 and will not be removed without replacement.
744 - Note that security issues shouldn't be reported using the bug tracker.
745 - Clarify what Privoxy does if both +block{} and +redirect{} apply.
746 - Removed the obsolete bookmarklets section.
748 - Build system improvements:
749 - Let --with-group properly deal with secondary groups.
750 Patch submitted by Anatoly Arzhnikov in #3615187.
751 - Fix web-actions target.
752 - Add a web-faq target that only updates the FAQ on the webserver.
753 - Remove already-commented-out non-portable DOSFILTER alternatives.
754 - Remove the obsolete targets dok-put and dok-get.
755 - Add a sf-shell target.
757 *** Version 3.0.21 stable ***
760 - On POSIX-like platforms, network sockets with file descriptor
761 values above FD_SETSIZE are properly rejected. Previously they
762 could cause memory corruption in configurations that allowed
763 the limit to be reached.
764 - Proxy authentication headers are removed unless the new directive
765 enable-proxy-authentication-forwarding is used. Forwarding the
766 headers potentially allows malicious sites to trick the user
767 into providing them with login information.
768 Reported by Chris John Riley.
769 - Compiles on OS/2 again now that unistd.h is only included
770 on platforms that have it.
772 - General improvements:
773 - The show-status page shows the FEATURE_STRPTIME_SANITY_CHECKS status.
774 - A couple of assert()s that could theoretically dereference
775 NULL pointers in debug builds have been relocated.
776 - Added an LSB info block to the generic start script.
777 Based on a patch from Natxo Asenjo.
778 - The max-client-connections default has been changed to 128
779 which should be more than enough for most setups.
781 - Action file improvements:
782 - Block rover.ebay./ar.*\&adtype= instead of "/.*\&adtype=" which
783 caused too man false positives.
784 Reported by u302320 in #360284, additional feedback from Adam Piggott.
785 - Unblock '.advrider.com/' and '/.*ADVrider'.
786 Anonymously reported in #3603636.
787 - Stop blocking '/js/slider\.js'.
788 Reported by Adam Piggott in #3606635 and _lvm in #2791160.
790 - Filter file improvements:
791 - Added an iframes filter.
793 - Documentation improvements:
794 - The whole GPLv2 text is included in the user manual now,
795 so Privoxy can serve it itself and the user can read it
796 without having to wade through GPLv3 ads first.
797 - Properly numbered and underlined a couple of section titles
798 in the config that where previously overlooked due to a flaw
799 in the conversion script. Reported by Ralf Jungblut.
800 - Improved the support instruction to hopefully make it harder to
801 unintentionally provide insufficient information when requesting
802 support. Previously it wasn't obvious that the information we need
803 in bug reports is usually also required in support requests.
804 - Removed documentation about packages that haven't been provided
807 - Privoxy-Regression-Test:
808 - Only log the test number when not running in verbose mode
809 The position of the test is rarely relevant and it previously
810 wasn't exactly obvious which one of the numbers was useful to
811 repeat the test with --test-number.
813 - GNUmakefile improvements:
814 - Factor generate-config-file out of config-file to make testing
816 - The clean target now also takes care of patch leftovers.
818 *** Version 3.0.20 beta ***
821 - Client sockets are now properly shutdown and drained before being
822 closed. This fixes page truncation issues with clients that aggressively
823 pipeline data on platforms that otherwise discard already written data.
824 The issue mainly affected Opera users and was initially reported
825 by Kevin in #3464439, szotsaki provided additional information to track
827 - Fix latency calculation for shared connections (disabled by default).
828 It was broken since their introduction in 2009. The calculated latency
829 for most connections would be 0 in which case the timeout detection
830 failed to account for the real latency.
831 - Reject URLs with invalid port. Previously they were parsed incorrectly and
832 characters between the port number and the first slash were silently
833 dropped as shown by curl test 187.
834 - The default-server-timeout and socket-timeout directives accept 0 as
836 - Fix a race condition on Windows that could cause Privoxy to become
837 unresponsive after toggling it on or off through the taskbar icon.
838 Reported by Tim H. in #3525694.
839 - Fix the compilation on Windows when configured without IPv6 support.
840 - Fix an assertion that could cause debug builds to abort() in case of
841 socks5 connection failures with "debug 2" enabled.
842 - Fix an assertion that could cause debug builds to abort() if a filter
843 contained nul bytes in the replacement text.
845 - General improvements:
846 - Significantly improved keep-alive support for both client and server
848 - New debug log level 65536 which logs all actions that were applied to
850 - New directive client-header-order to forward client headers in a
851 different order than the one in which they arrived.
852 - New directive tolerate-pipelining to allow client-side pipelining.
853 If enabled (3.0.20 beta enables it by default), Privoxy will keep
854 pipelined client requests around to deal with them once the current
855 request has been served.
856 - New --config-test option to let Privoxy exit after checking whether or not
857 the configuration seems valid. The limitations noted in TODO #22 and #23
858 still apply. Based on a patch by Ramkumar Chinchani.
859 - New limit-cookie-lifetime{} action to let cookies expire before the end
860 of the session. Suggested by Rick Sykes in #1049575.
861 - Increase the hard-coded maximum number of actions and filter files from
862 10 to 30 (each). It doesn't significantly affect Privoxy's memory usage
863 and recompiling wasn't an option for all Privoxy users that reached the
865 - Add support for chunk-encoded client request bodies. Previously
866 chunk-encoded request bodies weren't guaranteed to be forwarded correctly,
867 so this can also be considered a bug fix although chunk-encoded request
868 bodies aren't commonly used in the real world.
869 - Add support for Tor's optimistic-data SOCKS extension, which can reduce the
870 latency for requests on newly created connections. Currently only the
871 headers are sent optimistically and only if the client request has already
872 been read completely which rules out requests with large bodies.
873 - After preventing the client from pipelining, don't signal keep-alive
874 intentions. When looking at the response headers alone, it previously
875 wasn't obvious from the client's perspective that no additional responses
877 - Stop considering client sockets tainted after receiving a request with body.
878 It hasn't been necessary for a while now and unnecessarily causes test
879 failures when using curl's test suite.
880 - Allow HTTP/1.0 clients to signal interest in keep-alive through the
881 Proxy-Connection header. While such client are rare in the real world, it
882 doesn't hurt and couple of curl tests rely on it.
883 - Only remove duplicated Content-Type headers when filters are enabled.
884 If they are not it doesn't cause ill effects and the user might not want it.
885 Downgrade the removal message to LOG_LEVEL_HEADER to clarify that it's not
886 an error in Privoxy and is unlikely to cause any problems in general.
887 Anonymously reported in #3599335.
888 - Set the socket option SO_LINGER for the client socket.
889 - Move several variable declarations to the beginning of their code block.
890 It's required when compiling with gcc 2.95 which is still used on some
891 platforms. Initial patch submitted by Simon South in #3564815.
892 - Optionally try to sanity-check strptime() results before trusting them.
893 Broken strptime() implementations have caused problems in the past and
894 the most recent offender seems to be FreeBSD's libc (standards/173421).
895 - When filtering is enabled, let Range headers pass if the range starts at
896 the beginning. This should work around (or at least reduce) the video
897 playback issues with various Apple clients as reported by Duc in #3426305.
898 - Do not confuse a client hanging up with a connection time out. If a client
899 closes its side of the connection without sending a request line, do not
900 send the CLIENT_CONNECTION_TIMEOUT_RESPONSE, but report the condition
902 - Allow closing curly braces as part of action values as long as they are
904 - On Windows, the logfile is now written before showing the GUI error
905 message which blocks until the user acknowledges it.
906 Reported by Adriaan in #3593603.
907 - Remove an unreasonable parameter limit in the CGI interface. The new
908 parameter limit depends on the memory available and is currently unlikely
909 to be reachable, due to other limits in both Privoxy and common clients.
910 Reported by Andrew on ijbswa-users@.
911 - Decrease the chances of parse failures after requests with unsupported
912 methods were sent to the CGI interface.
914 - Action file improvements:
915 - Remove the comment that indicated that updated default.action versions
916 are released on their own.
917 - Block 'optimize.indieclick.com/' and 'optimized-by.rubiconproject.com/'
918 - Unblock 'adjamblog.wordpress.com/' and 'adjamblog.files.wordpress.com/'.

957 Fixes #3413827 submitted by David Bo.
958 - Add two unblock patterns for popup radio and TV players.
959 Submitted by Adam Piggott in #3596089.
961 - Filter file improvements & bug fixes:
962 - Add a referer tagger.
963 - Reduce the likelihood that the google filter messes up HTML-generating
964 JavaScript. Reported by Zeno Kugy in #3520260.
966 - Documentation improvements:
967 - Revised all OS X sections due to new packaging module (OSXPackageBuilder).
968 - Update the list of supported operating systems to clarify that all Windows
969 versions after 95 are expected to work and note that the platform-specific
970 code for AmigaOS and QNX currently isn't maintained.
971 - Update 'Signals' section, the only explicitly handled signals are SIGINT,
973 - Add Haiku to the list of operating systems on which Privoxy is known to
975 - Add DragonFly to the list of BSDs on which Privoxy is known to run.
976 - Removed references to redhat-specific documentation set since it no longer
978 - Removed references to building PDFs since we no longer do so.
979 - Multiple listen-address directives are supported since 3.0.18, correct the
980 documentation to say so.
981 - Remove bogus section about long and short being preferable to int.
982 - Corrected some Internet JunkBuster references to Privoxy.
983 - Removed references to www.junkbusters.com since it is no longer
984 maintained. Reported by Angelina Matson.
985 - Various grammar and spelling corrections
986 - Add a client-header-tagger{} example for disabling filtering for range
988 - Correct a URL in the "Privoxy with Tor" FAQ.
989 - Spell 'refresh-tags' correctly. Reported by Don in #3571927.
990 - Sort manpage options alphabetically.
991 - Remove an incorrect sentence in the toggle section. The toggle state
992 doesn't affect whether or not the Windows version uses the tray icon.
993 Reported by Zeno Kugy in #3596395.
994 - Add new contributors since 3.0.19.
996 - Log message improvements:
997 - When stopping to watch a client socket due to pipelining, additionally log
999 - Log the client socket and its condition before closing it. This makes it
1000 more obvious that the socket actually gets closed and should help when
1001 diagnosing problems like #3464439.
1002 - In case of SOCKS5 failures, do not explicitly log the server's response.
1003 It hasn't helped so far and the response can already be logged by enabling
1004 "debug 32768" anyway. This reverts v1.81 and the follow-up bug fix v1.84.
1005 - Relocate the connection-accepted message from listen_loop() to serve().
1006 This way it's printed by the thread that is actually serving the
1007 connection which is nice when grepping for thread ids in log files.
1010 - Remove compatibility layer for versions prior to 3.0 since it has been
1011 obsolete for more than 10 years now.
1012 - Remove the ijb_isupper() and ijb_tolower() macros from parsers.c since
1013 they aren't used in this file.
1014 - Removed the 'Functions declared include:' comment sections since they tend
1015 to be incomplete, incorrect and out of date and the benefit seems
1017 - Various comment grammar and comprehensibility improvements.
1018 - Remove a pointless fflush() call in chat(). Flushing all streams pretty
1019 much all the time for no obvious reason is ridiculous.
1020 - Relocate ijb_isupper()'s definition to project.h and get the ijb_tolower()
1021 definition from there, too.
1022 - Relocate ijb_isdigit()'s definition to project.h.
1023 - Rename ijb_foo macros to privoxy_foo.
1024 - Add malloc_or_die() which will allow to simplify code paths where malloc()
1025 failures don't need to be handled gracefully.
1026 - Add strdup_or_die() which will allow to simplify code paths where strdup()
1027 failures don't need to be handled gracefully.
1028 - Replace strdup() calls with strdup_or_die() calls where it's safe and
1029 simplifies the code.
1030 - Fix white-space around parentheses.
1031 - Add missing white-space behind if's and the following parentheses.
1032 - Unwrap a memcpy() call in resolve_hostname_to_ip().
1033 - Declare pcrs_get_delimiter()'s delimiters[] static const.
1034 - Various optimisations to remove dead code and merge inefficient code
1035 structures for improved clarity, performance or code compactness.
1036 - Various data type corrections.
1037 - Change visibility of several code segments when compiling without
1038 FEATURE_CONNECTION_KEEP_ALIVE enabled for clarity.
1039 - In pcrs_get_delimiter(), do not use delimiters outside the ASCII range.
1040 Fixes a clang complaint.
1041 - Fix an error message in get_last_url() nobody is supposed to see.
1042 Reported by Matthew Fischer in #3507301.
1043 - Fix a typo in the no-zlib-support complaint. Patch submitted by Matthew
1044 Fischer in #3507304.
1045 - Shorten ssplit()'s prototype by removing the last two arguments. We always
1046 want to skip empty fields and ignore leading delimiters, so having
1047 parameters for this only complicates the API.
1048 - Use an enum for the type of the action value.
1049 - Rename action_name's member takes_value to value_type as it isn't used as
1051 - Turn family mismatches in match_sockaddr() into fatal errors.
1052 - Let enlist_unique_header() verify that the caller didn't pass a header
1053 containing either \r or \n.
1054 - Change the hashes used in load_config() to unsigned int. That's what
1055 hash_string() actually returns and using a potentially larger type
1057 - Use privoxy_tolower() instead of vanilla tolower() with manual casting of
1059 - Catch ssplit() failures in parse_cgi_parameters().
1061 - Privoxy-Regression-Test:
1062 - Add an 'Overwrite condition' directive to skip any matching tests before
1063 it. As it has a global scope, using it is more convenient than clowning
1064 around with the Ignore directive.
1065 - Log to STDOUT instead of STDERR.
1066 - Include the Privoxy version in the output.
1067 - Various grammar and spelling corrections in documentation and code.
1068 - Additional tests for range requests with filtering enabled.
1069 - Tests with mostly invalid range request.
1070 - Add a couple of hide-if-modified-since{} tests with different date formats.
1071 - Cleaned up the format of the regression-tests.action file to match the
1072 format of default.action.
1073 - Remove the "Copyright" line from print_version(). When using --help, every
1074 line of screen space matters and thus shouldn't be wasted on things the
1075 user doesn't care about.
1077 - Privoxy-Log-Parser:
1078 - Improve the --statistics performance by skipping sanity checks for input
1079 that shouldn't affect the results anyway. Add a --strict-checks option
1080 that enables some of the checks again, just in case anybody cares.
1081 - The distribution of client requests per connection is included in
1082 the --statistic output.
1083 - The --accept-unknown-messages option has been removed and the behavior
1085 - Accept and (mostly) highlight new log messages introduced with
1089 - Bump generated Firefox version to 17.
1091 - GNUmakefile improvements:
1092 - The dok-tidy target no longer taints documents with a tidy-mark
1093 - Change RA_MODE from 0664 to 0644. Suggested by Markus Dittrich in
1095 - Remove tidy's clean flag as it changes the scope of attributes.
1096 Link-specific colors end up being applied to all text. Reported by Adam
1097 Piggott in #3569551.
1098 - Leave it up to the user whether or not smart tags are inserted.
1099 - Let w3m itself do the line wrapping for the config file. It works better
1100 than fmt as it can honour pre tags causing less unintentional line breaks.
1101 - Ditch a pointless '-r' passed to rm to delete files.
1102 - The config-file target now requires less manual intervention and updates
1103 the original config.
1104 - Change WDUMP to generate ASCII. Add WDUMP_UTF8 to allow UTF-8 in the
1105 AUTHORS file so the names are right.
1106 - Stop pretending that lynx and links are supported for the documentation.
1108 - configure improvements:
1109 - On Haiku, do not pass -lpthread to the compiler. Haiku's pthreads
1110 implementation is contained in its system library, libroot, so no
1111 additional library needs to be searched.
1112 Patch submitted by Simon South in #3564815.
1113 - Additional Haiku-specific improvements. Disable checks intended for
1114 multi-user systems as Haiku is presently single-user. Group Haiku-specific
1115 settings in their own section, following the pattern for Solaris, OS/2 and
1116 AmigaOS. Add additional library-related settings to remove the need for
1117 providing configure with custom LDFLAGS.
1118 Submitted by Simon South in #3574538.
1120 *** Version 3.0.19 Stable ***
1123 - Prevent a segmentation fault when de-chunking buffered content.
1124 It could be triggered by malicious web servers if Privoxy was
1125 configured to filter the content and running on a platform
1126 where SIZE_T_MAX isn't larger than UINT_MAX, which probably
1127 includes most 32-bit systems. On those platforms, all Privoxy
1128 versions before 3.0.19 appear to be affected.
1129 To be on the safe side, this bug should be presumed to allow
1130 code execution as proving that it doesn't seems unrealistic.
1131 - Do not expect a response from the SOCKS4/4A server until it
1132 got something to respond to. This regression was introduced
1133 in 3.0.18 and prevented the SOCKS4/4A negotiation from working.
1134 Reported by qqqqqw in #3459781.
1136 - General improvements:
1137 - Fix an off-by-one in an error message about connect failures.
1138 - Use a GNUMakefile variable for the webserver root directory and
1139 update the path. Sourceforge changed it which broke various
1140 web-related targets.
1141 - Update the CODE_STATUS description.
1143 *** Version 3.0.18 Stable ***
1146 - If a generated redirect URL contains characters RFC 3986 doesn't
1147 permit, they are (re)encoded. Not doing this makes Privoxy versions
1148 from 3.0.5 to 3.0.17 susceptible to HTTP response splitting (CWE-113)
1149 attacks if the +fast-redirects{check-decoded-url} action is used.
1150 - Fix a logic bug that could cause Privoxy to reuse a server
1151 socket after it got tainted by a server-header-tagger-induced
1152 block that was triggered before the whole server response had
1153 been read. If keep-alive was enabled and the request following
1154 the blocked one was to the same host and using the same forwarding
1155 settings, Privoxy would send it on the tainted server socket.
1156 While the server would simply treat it as a pipelined request,
1157 Privoxy would later on fail to properly parse the server's
1158 response as it would try to parse the unread data from the
1159 first response as server headers for the second one.
1160 Regression introduced in 3.0.17.
1161 - When implying keep-alive in client_connection(), remember that
1162 the client didn't. Fixes a regression introduced in 3.0.13 that
1163 would cause Privoxy to wait for additional client requests after
1164 receiving a HTTP/1.1 request with "Connection: close" set
1165 and connection sharing enabled.
1166 With clients which terminates the client connection after detecting
1167 that the whole body has been received it doesn't really matter,
1168 but with clients that don't the connection would be kept open until
1170 - Fix a subtle race condition between prepare_csp_for_next_request()
1171 and sweep(). A thread preparing itself for the next client request
1172 could briefly appear to be inactive.
1173 If all other threads were already using more recent files,
1174 the thread could get its files swept away under its feet.
1175 So far this has only been reproduced while stress testing in
1176 valgrind while touching action files in a loop. It's unlikely
1177 to have caused any actual problems in the real world.
1178 - Disable filters if SDCH compression is used unless filtering is forced.
1179 If SDCH was combined with a supported compression algorithm, Privoxy
1180 previously could try to decompress it and ditch the Content-Encoding
1181 header even though the SDCH compression wasn't dealt with.
1182 Reported by zebul666 in #3225863.
1183 - Make a copy of the --user value and only mess with that when splitting
1184 user and group. On some operating systems modifying the value directly
1185 is reflected in the output of ps and friends and can be misleading.
1186 Reported by zepard in #3292710.
1187 - If forwarded-connect-retries is set, only retry if Privoxy is actually
1188 forwarding the request. Previously direct connections would be retried
1190 - Fixed a small memory leak when retrying connections with IPv6
1192 - Remove an incorrect assertion in compile_dynamic_pcrs_job_list()
1193 It could be triggered by a pcrs job with an invalid pcre
1194 pattern (for example one that contains a lone quantifier).
1195 - If the --user argument user[.group] contains a dot, always bail out
1196 if no group has been specified. Previously the intended, but undocumented
1197 (and apparently untested), behaviour was to try interpreting the whole
1198 argument as user name, but the detection was flawed and checked for '0'
1199 instead of '\0', thus merely preventing group names beginning with a zero.
1200 - In html_code_map[], use a numeric character reference instead of '
1201 which wasn't standardized before XHTML 1.0.
1202 - Fix an invalid free when compiled with FEATURE_GRACEFUL_TERMINATION
1203 and shut down through http://config.privoxy.org/die
1204 - In get_actions(), fix the "temporary" backwards compatibility hack
1205 to accept block actions without reason.
1206 It also covered other actions that should be rejected as invalid.
1207 Reported by Billy Crook.
1209 - General improvements:
1210 - Privoxy can (re)compress buffered content before delivering
1211 it to the client. Disabled by default as most users wouldn't
1213 - The +fast-redirects{check-decoded-url} action checks URL
1214 segments separately. If there are other parameters behind
1215 the redirect URL, this makes it unnecessary to cut them off
1216 by additionally using a +redirect{} pcrs command.
1217 Initial patch submitted by Jamie Zawinski in #3429848.
1218 - When loading action sections, verify that the referenced filters
1219 exist. Currently missing filters only result in an error message,
1220 but eventually the severity will be upgraded to fatal.
1221 - Allow to bind to multiple separate addresses.
1222 Patch set submitted by Petr Pisar in #3354485.
1223 - Set socket_error to errno if connecting fails in rfc2553_connect_to().
1224 Previously rejected direct connections could be incorrectly reported
1225 as DNS issues if Privoxy was compiled with IPv6 support.
1226 - Adjust url_code_map[] so spaces are replaced with %20 instead of '+'
1227 While '+' can be used by client's submitting form data, this is not
1228 actually what Privoxy is using the lookups for. This is more of a
1229 cosmetic issue and doesn't fix any known problems.
1230 - When compiled without FEATURE_FAST_REDIRECTS, do not silently
1231 ignore +fast-redirect{} directives
1232 - Added a workaround for GNU libc's strptime() reporting negative
1233 year values when the parsed year is only specified with two digits.
1234 On affected systems cookies with such a date would not be turned
1235 into session cookies by the +session-cookies-only action.
1236 Reported by Vaeinoe in #3403560
1237 - Fixed bind failures with certain GNU libc versions if no non-loopback
1238 IP address has been configured on the system. This is mainly an issue
1239 if the system is using DHCP and Privoxy is started before the network
1240 is completely configured.
1241 Reported by Raphael Marichez in #3349356.
1242 Additional insight from Petr Pisar.
1243 - Privoxy log messages now use the ISO 8601 date format %Y-%m-%d.
1244 It's only slightly longer than the old format, but contains
1245 the full date including the year and allows sorting by date
1246 (when grepping in multiple log files) without hassle.
1247 - In get_last_url(), do not bother trying to decode URLs that do
1248 not contain at least one '%' sign. It reduces the log noise and
1249 a number of unnecessary memory allocations.
1250 - In case of SOCKS5 failures, dump the socks response in the log message.
1251 - Simplify the signal setup in main().
1252 - Streamline socks5_connect() slightly.
1253 - In socks5_connect(), require a complete socks response from the server.
1254 Previously Privoxy didn't care how much data the server response
1255 contained as long as the first two bytes contained the expected
1256 values. While at it, shrink the buffer size so Privoxy can't read
1257 more than a whole socks response.
1258 - In chat(), do not bother to generate a client request in case of
1259 direct CONNECT requests. It will not be used anyway.
1260 - Reduce server_last_modified()'s stack size.
1261 - Shorten get_http_time() by using strftime().
1262 - Constify the known_http_methods pointers in unknown_method().
1263 - Constify the time_formats pointers in parse_header_time().
1264 - Constify the formerly_valid_actions pointers in action_used_to_be_valid().
1265 - Introduce a GNUMakefile MAN_PAGE variable that defaults to privoxy.1.
1266 The Debian package uses section 8 for the man page and this
1267 should simplify the patch.
1268 - Deduplicate the INADDR_NONE definition for Solaris by moving it to jbsockets.h
1269 - In block_url(), ditch the obsolete workaround for ancient Netscape versions
1270 that supposedly couldn't properly deal with status code 403.
1271 - Remove a useless NULL pointer check in load_trustfile().
1272 - Remove two useless NULL pointer checks in load_one_re_filterfile().
1273 - Change url_code_map[] from an array of pointers to an array of arrays
1274 It removes an unnecessary layer of indirection and on 64bit system reduces
1275 the size of the binary a bit.
1276 - Fix various typos. Fixes taken from Debian's 29_typos.dpatch by Roland Rosenfeld.
1277 - Add a dok-tidy GNUMakefile target to clean up the messy HTML
1278 generated by the other dok targets.
1279 - GNUisms in the GNUMakefile have been removed.
1280 - Change the HTTP version in static responses to 1.1
1281 - Synced config.sub and config.guess with upstream
1282 2011-11-11/386c7218162c145f5f9e1ff7f558a3fbb66c37c5.
1283 - Add a dedicated function to parse the values of toggles. Reduces duplicated
1284 code in load_config() and provides better error handling. Invalid or missing
1285 toggle values are now a fatal error instead of being silently ignored.
1286 - Terminate HTML lines in static error messages with \n instead of \r\n.
1287 - Simplify cgi_error_unknown() a bit.
1288 - In LogPutString(), don't bother looking at pszText when not
1289 actually logging anything.
1290 - Change ssplit()'s fourth parameter from int to size_t.
1291 Fixes a clang complaint.
1292 - Add a warning that the statistics currently can't be trusted.
1293 Mention Privoxy-Log-Parser's --statistics option as
1294 an alternative for the time being.
1295 - In rfc2553_connect_to(), start setting cgi->error_message on error.
1296 - Change the expected status code returned for http://p.p/die depending
1297 on whether or not FEATURE_GRACEFUL_TERMINATION is available.
1298 - In cgi_die(), mark the client connection for closing.
1299 If the client will fetch the style sheet through another connection
1300 it gets the main thread out of the accept() state and should thus
1301 trigger the actual shutdown.
1302 - Add a proper CGI message for cgi_die().
1303 - Don't enforce a logical line length limit in read_config_line().
1304 - Slightly refactor server_last_modified() to remove useless gmtime*() calls.
1305 - In get_content_type(), also recognize '.jpeg' as JPEG extension.
1306 - Add '.png' to the list of recognized file extensions in get_content_type().
1307 - In block_url(), consistently use the block reason "Request blocked by Privoxy"
1308 In two places the reason was "Request for blocked URL" which hides the
1309 fact that the request got blocked by Privoxy and isn't necessarily
1310 correct as the block may be due to tags.
1311 - In listen_loop(), reload the configuration files after accepting
1312 a new connection instead of before.
1313 Previously the first connection that arrived after a configuration
1314 change would still be handled with the old configuration.
1315 - In chat()'s receive-data loop, skip a client socket check if
1316 the socket will be written to right away anyway. This can
1317 increase the transfer speed for unfiltered content on fast
1318 network connections.
1319 - The socket timeout is used for SOCKS negotiations as well which
1320 previously couldn't timeout.
1321 - Don't keep the client connection alive if any configuration file
1322 changed since the time the connection came in. This is closer to
1323 Privoxy's behaviour before keep-alive support for client connection
1324 has been added and also less confusing in general.
1325 - Treat all Content-Type header values containing the pattern
1326 'script' as a sign of text. Reported by pribog in #3134970.
1328 - Action file improvements:
1329 - Moved the site-specific block pattern section below the one for the
1330 generic patterns so for requests that are matched in both, the block
1331 reason for the domain is shown which is usually more useful than showing
1332 the one for the generic pattern.
1333 - Remove -prevent-compression from the fragile alias. It's no longer
1334 used anywhere by default and isn't known to break stuff anyway.
1335 - Add a (disabled) section to block various Facebook tracking URLs.
1336 Reported by Dan Stahlke in #3421764.
1337 - Add a (disabled) section to rewrite and redirect click-tracking
1338 URLs used on news.google.com.
1339 Reported by Dan Stahlke in #3421755.
1340 - Unblock linuxcounter.net/.
1341 Reported by Dan Stahlke in #3422612.
1342 - Block 'www91.intel.com/' which is used by Omniture.
1343 Reported by Adam Piggott in #3167370.
1344 - Disable the handle-as-empty-doc-returns-ok option and mark it as deprecated.
1345 Reminded by tceverling in #2790091.
1346 - Add ".ivwbox.de/" to the "Cross-site user tracking" section.
1347 Reported by Nettozahler in #3172525.
1348 - Unblock and fast-redirect ".awin1.com/.*=http://".
1349 Reported by Adam Piggott in #3170921.
1350 - Block "b.collective-media.net/".
1351 - Widen the Debian popcon exception to "qa.debian.org/popcon".
1352 Seen in Debian's 05_default_action.dpatch by Roland Rosenfeld.
1353 - Block ".gemius.pl/" which only seems to be used for user tracking.
1354 Reported by johnd16 in #3002731. Additional input from Lee and movax.
1355 - Disable banners-by-size filters for '.thinkgeek.com/'.
1356 The filter only seems to catch pictures of the inventory.
1357 - Block requests for 'go.idmnet.bbelements.com/please/showit/'.
1358 Reported by kacperdominik in #3372959.
1359 - Unblock adainitiative.org/.
1360 - Add a fast-redirects exception for '.googleusercontent.com/.*=cache'.
1361 - Add a fast-redirects exception for webcache.googleusercontent.com/.
1362 - Unblock http://adassier.wordpress.com/ and http://adassier.files.wordpress.com/.
1364 - Filter file improvements:
1365 - Let the yahoo filter hide '.ads'.
1366 - Let the msn filter hide overlay ads for Facebook 'likes' in search
1367 results and elements with the id 's_notf_div'. They only seem to be
1368 used to advertise site 'enhancements'.
1369 - Let the js-events filter additionally disarm setInterval().
1370 Suggested by dg1727 in #3423775.
1372 - Documentation improvements:
1373 - Clarify the effect of compiling Privoxy with zlib support.
1374 Suggested by dg1727 in #3423782.
1375 - Point out that the SourceForge messaging system works like a black
1376 hole and should thus not be used to contact individual developers.
1377 - Mention some of the problems one can experience when not explicitly
1378 configuring an IP addresses as listen address.
1379 - Explicitly mention that hostnames can be used instead of IP addresses
1380 for the listen-address, that only the first address returned will be
1381 used and what happens if the address is invalid.
1382 Requested by Calestyo in #3302213.
1384 - Log message improvements:
1385 - If only the server connection is kept alive, do not pretend to
1386 wait for a new client request.
1387 - Remove a superfluous log message in forget_connection().
1388 - In chat(), properly report missing server responses as such
1389 instead of calling them empty.
1390 - In forwarded_connect(), fix a log message nobody should ever see.
1391 - Fix a log message in socks5_connect(), a failed write operation
1392 was logged as failed read operation.
1393 - Let load_one_actions_file() properly complain about a missing
1394 '{' at the beginning of the file.
1395 Simply stating that a line is invalid isn't particularly helpful.
1396 - Do not claim to listen on a socket until Privoxy actually does.
1397 Patch submitted by Petr Pisar #3354485
1398 - Prevent a duplicated LOG_LEVEL_CLF message when sending out
1399 the "no-server-data" response.
1400 - Also log the client socket when dropping a connection.
1401 - Include the destination host in the 'Request ... marked for
1402 blocking. limit-connect{...} doesn't allow CONNECT ...' message
1403 Patch submitted by Saperski in #3296250.
1404 - Prevent a duplicated log message if none of the resolved IP
1405 addresses were reachable.
1406 - In connect_to(), do not pretend to retry if forwarded-connect-retries
1408 - When a specified user or group can't be found, put the name in
1409 single-quotes when logging it.
1410 - In rfc2553_connect_to(), explain getnameinfo() errors better.
1411 - Remove a useless log message in chat().
1412 - When retrying to connect, also log the maximum number of connection
1414 - Rephrase a log message in compile_dynamic_pcrs_job_list().
1415 Divide the error code and its meaning with a colon. Call the pcrs
1416 job dynamic and not the filter. Filters may contain dynamic and
1417 non-dynamic pcrs jobs at the same time. Only mention the name of
1418 the filter or tagger, but don't claim it's a filter when it could
1420 - In a fatal error message in load_one_actions_file(), cover both
1421 URL and TAG patterns.
1422 - In pcrs_strerror(), properly report unknown positive error code
1423 values as such. Previously they were handled like 0 (no error).
1424 - In compile_dynamic_pcrs_job_list(), also log the actual error code as
1425 pcrs_strerror() doesn't handle all errors reported by pcre.
1426 - Don't bother trying to continue chatting if the client didn't ask for it.
1427 Reduces log noise a bit.
1428 - Make two fatal error message in load_one_actions_file() more descriptive.
1429 - In cgi_send_user_manual(), log when rejecting a file name due to '/' or '..'.
1430 - In load_file(), log a message if opening a file failed.
1431 The CGI error message alone isn't too helpful.
1432 - In connection_destination_matches(), improve two log messages
1433 to help understand why the destinations don't match.
1434 - Rephrase a log message in serve(). Client request arrival
1435 should be differentiated from closed client connections now.
1436 - In serve(), log if a client connection isn't reused due to a
1437 configuration file change.
1438 - Let mark_server_socket_tainted() always mark the server socket tainted,
1439 just don't talk about it in cases where it has no effect. It doesn't change
1440 Privoxy's behaviour, but makes understanding the log file easier.
1443 - Added a --disable-ipv6-support switch for platforms where support
1444 is detected but doesn't actually work.
1445 - Do not check for the existence of strerror() and memmove() twice
1446 - Remove a useless test for setpgrp(2). Privoxy doesn't need it and
1447 it can cause problems when cross-compiling.
1448 - Rename the --disable-acl-files switch to --disable-acl-support.
1449 Since about 2001, ACL directives are specified in the standard
1451 - Update the URL of the 'Removing outdated PCRE version after the
1452 next stable release' posting. The old URL stopped working after
1453 one of SF's recent site "optimizations". Reported by Han Liu.
1455 - Privoxy-Regression-Test:
1456 - Added --shuffle-tests option to increase the chances of detection race conditions.
1457 - Added a --local-test-file option that allows to use Privoxy-Regression-Test without Privoxy.
1458 - Added tests for missing socks4 and socks4a forwarders.
1459 - The --privoxy-address option now works with IPv6 addresses containing brackets, too.
1460 - Perform limited sanity checks for parameters that are supposed to have numerical values.
1461 - Added a --sleep-time option to specify a number of seconds to
1462 sleep between tests, defaults to 0.
1463 - Disable the range-requests tagger for tests that break if it's enabled.
1464 - Log messages use the ISO 8601 date format %Y-%m-%d.
1465 - Fix spelling in two error messages.
1466 - In the --help output, include a list of supported tests and their default levels.
1467 - Adjust the tests to properly deal with FEATURE_TOGGLE being disabled.
1469 - Privoxy-Log-Parser:
1470 - Perform limited sanity checks for command line parameters that
1471 are supposed to have numerical values.
1472 - Implement a --unbreak-lines-only option to try to revert MUA breakage.
1473 - Accept and highlight: Added header: Content-Encoding: deflate
1474 - Accept and highlight: Compressed content from 29258 to 8630 bytes.
1475 - Accept and highlight: Client request arrived in time on socket 21.
1476 - Highlight: Didn't receive data in time: a.fsdn.com:443
1477 - Accept log messages with ISO 8601 time stamps, too.
1480 - Bump generated Firefox version to 8.0.
1481 - Only randomize the release date if the new --randomize-release-date
1482 option is enabled. Firefox versions after 4 use a fixed date string
1485 *** Version 3.0.17 Stable ***
1487 - Fixed last-chunk-detection for responses where the body was small
1488 enough to be read with the headers, causing Privoxy to wait for the
1489 end of the content until the server closed the connection or the
1490 request timed out. Reported by "Karsten" in #3028326.
1491 - Responses with status code 204 weren't properly detected as body-less
1492 like RFC2616 mandates. Like the previous bug, this caused Privoxy to
1493 wait for the end of the content until the server closed the connection
1494 or the request timed out. Fixes #3022042 and #3025553, reported by a
1495 user with no visible name. Most likely also fixes a bunch of other
1496 AJAX-related problem reports that got closed in the past due to
1497 insufficient information and lack of feedback.
1498 - Fixed an ACL bug that made it impossible to build a blacklist.
1499 Usually the ACL directives are used in a whitelist, which worked
1500 as expected, but blacklisting is still useful for public proxies
1501 where one only needs to deny known abusers access.
1502 - Added LOG_LEVEL_RECEIVED to log the not-yet-parsed data read from the
1503 network. This should make debugging various parsing issues a lot easier.
1504 - The IPv6 code is enabled by default on Windows versions that support it.
1505 Patch submitted by oCameLo in #2942729.
1506 - In mingw32 versions, the user.filter file is reachable through the
1507 GUI, just like default.filter is. Feature request 3040263.
1508 - Added the configure option --enable-large-file-support to set a few
1509 defines that are required by platforms like GNU/Linux to support files
1510 larger then 2GB. Mainly interesting for users without proper logfile
1512 - Logging with "debug 16" no longer stops at the first nul byte which is
1513 pretty useless. Non-printable characters are replaced with their hex value
1514 so the result can't span multiple lines making parsing them harder then
1516 - Privoxy logs when reading an action, filter or trust file.
1517 - Fixed incorrect regression test markup which caused a test in
1518 3.0.16 to fail while Privoxy itself was working correctly.
1519 While Privoxy accepts hide-referer, too, the action name is actually
1520 hide-referrer which is also the name used one the final results page,
1521 where the test expected the alias.
1523 - CGI interface improvements:
1524 - In finish_http_response(), continue to add the 'Connection: close'
1525 header if the client connection will not be kept alive.
1526 Anonymously pointed out in #2987454.
1527 - Apostrophes in block messages no longer cause parse errors
1528 when the blocked page is viewed with JavaScript enabled.
1529 Reported by dg1727 in #3062296.
1530 - Fix a bunch of anchors that used underscores instead of dashes.
1531 - Allow to keep the client connection alive after crunching the previous request.
1532 Already opened server connections can be kept alive, too.
1533 - In cgi_show_url_info(), don't forget to prefix URLs that only contain
1534 http:// or https:// in the path. Fixes #2975765 reported by Adam Piggott.
1535 - Show the 404 CGI page if cgi_send_user_manual() is called while
1536 local user manual delivery is disabled.
1538 - Action file improvements:
1539 - Enable user.filter by default. Suggested by David White in #3001830.
1540 - Block .sitestat.com/. Reported by johnd16 in #3002725.
1541 - Block .atemda.com/. Reported by johnd16 in #3002723.
1542 - Block js.adlink.net/. Reported by johnd16 in #3002720.
1543 - Block .analytics.yahoo.com/. Reported by johnd16 in #3002713.
1544 - Block sb.scorecardresearch.com, too. Reported by dg1727 in #2992652.
1545 - Fix problems noticed on Yahoo mail and news pages.
1546 - Remove the too broad yahoo section, only keeping the
1547 fast-redirects exception as discussed on ijbswa-devel@.
1548 - Don't block adesklets.sourceforge.net. Reported in #2974204.
1549 - Block chartbeat ping tracking. Reported in #2975895.
1550 - Tag CSS and image requests with cautious and medium settings, too.
1551 - Don't handle view.atdmt.com as image. It's used for click-throughs
1552 so users should be able to "go there anyway".
1553 Reported by Adam Piggott in #2975927.
1554 - Also let the refresh-tags filter remove invalid refresh tags where
1555 the 'url=' part is missing. Anonymously reported in #2986382.
1556 While at it, update the description to mention the fact that only
1557 refresh tags with refresh times above 9 seconds are covered.
1558 - javascript needs to be blocked with +handle-as-empty-document to
1559 work around Firefox bug 492459. So move .js blockers from
1560 +block{Might be a web-bug.} -handle-as-empty-document to
1561 +block{Might be a web-bug.} +handle-as-empty-document.
1562 - ijbswa-Feature Requests-3006719 - Block 160x578 Banners.
1563 - Block another omniture tracking domain.
1564 - Added a range-requests tagger.
1565 - Added two sections to get Flickr's Ajax interface working with
1566 default pre-settings. If you change the configuration to block
1567 cookies by default, you'll need additional exceptions.
1568 Reported by Mathias Homann in #3101419 and by Patrick on ijbswa-users@.
1570 - Documentation improvements:
1571 - Explicitly mention how to match all URLs.
1572 - Consistently recommend socks5 in the Tor FAQ entry and mention
1573 its advantage compared to socks4a. Reported by David in #2960129.
1574 - Slightly improve the explanation of why filtering may appear
1576 - Grammar fixes for the ACL section.
1577 - Fixed a link to the 'intercepting' entry and add another one.
1578 - Rename the 'Other' section to 'Mailing Lists' and reword it
1579 to make it clear that nobody is forced to use the trackers
1580 - Note that 'anonymously' posting on the trackers may not always
1582 - Suggest to enable debug 32768 when suspecting parsing problems.
1584 - Privoxy-Log-Parser improvements:
1585 - Gather statistics for ressources, methods, and HTTP versions
1587 - Also gather statistics for blocked and redirected requests.
1588 - Provide the percentage of keep-alive offers the client accepted.
1589 - Add a --url-statistics-threshold option.
1590 - Add a --host-statistics-threshold option to also gather
1591 statistics about how many request where made per host.
1592 - Fix a bug in handle_loglevel_header() where a 'scan: ' got lost.
1593 - Add a --shorten-thread-ids option to replace the thread id with
1595 - Accept and ignore: Looks like we got the last chunk together
1596 with the server headers. We better stop reading.
1597 - Accept and ignore: Continue hack in da house.
1598 - Accept and higlight: Rejecting connection from 10.0.0.2.
1599 Maximum number of connections reached.
1600 - Accept and highlight: Loading actions file: /usr/local/etc/privoxy/default.action
1601 - Accept and highlight: Loading filter file: /usr/local/etc/privoxy/default.filter
1602 - Accept and highlight: Killed all-caps Host header line: HOST: bestproxydb.com
1603 - Accept and highlight: Reducing expected bytes to 0. Marking
1604 the server socket tainted after throwing 4 bytes away.
1605 - Accept: Merged multiple header lines to: 'X-FORWARDED-PROTO: http X-HOST: 127.0.0.1'
1608 - Remove the next member from the client_state struct. Only the main
1609 thread needs access to all client states so give it its own struct.
1610 - Garbage-collect request_contains_null_bytes().
1611 - Ditch redundant code in unload_configfile().
1612 - Ditch LogGetURLUnderCursor() which doesn't seem to be used anywhere.
1613 - In write_socket(), remove the write-only variable write_len in
1614 an ifdef __OS2__ block. Spotted by cppcheck.
1615 - In connect_to(), don't declare the variable 'flags' on OS/2 where
1616 it isn't used. Spotted by cppcheck.
1617 - Limit the scope of various variables. Spotted by cppcheck.
1618 - In add_to_iob(), turn an interestingly looking for loop into a
1620 - Code cleanup in preparation for external filters.
1621 - In listen_loop(), mention the socket on which we accepted the
1622 connection, not just the source IP address.
1623 - In write_socket(), also log the socket we're writing to.
1624 - In log_error(), assert that escaped characters get logged
1625 completely or not at all.
1626 - In log_error(), assert that ival and sval have reasonable values.
1627 There's no reason not to abort() if they don't.
1628 - Remove an incorrect cgi_error_unknown() call in a
1629 cannot-happen-situation in send_crunch_response().
1630 - Clean up white-space in http_response definition and
1631 move the crunch_reason to the beginning.
1632 - Turn http_response.reason into an enum and rename it
1633 to http_response.crunch_reason.
1634 - Silence a 'gcc (Debian 4.3.2-1.1) 4.3.2' warning on i686 GNU/Linux.
1635 - Fix white-space in a log message in remove_chunked_transfer_coding().
1636 While at it, add a note that the message doesn't seem to
1637 be entirely correct and should be improved later on.
1639 - GNUmakefile improvements:
1640 - Use $(SSH) instead of ssh, so one only needs to specify a username once.
1641 - Removed references to the action feedback thingy that hasn't been
1643 - Consistently use shell.sourceforge.net instead of shell.sf.net so
1644 one doesn't need to check server fingerprints twice.
1645 - Removed GNUisms in the webserver and webactions targets so they
1646 work with standard tar.
1648 *** Version 3.0.16 Stable ***
1650 - Added the config file option handle-as-empty-doc-returns-ok to
1651 work around Firefox bug #492459, which causes Firefox to hang
1652 if JavaScripts are blocked in certain situations. The option is
1653 enabled in the default config file.
1654 - Added the config file option default-server-timeout to control the
1655 assumed default server timeout. Since Privoxy no longer returns
1656 an error message for connection resets on reused client connections,
1657 assuming larger server timeout values appears to actually work
1658 pretty well as long as connections aren't shared.
1659 - Added optional support for FreeBSD's accf_http(9). Use the
1660 configure option --enable-accept-filter to enable it.
1661 - Added fancier Privoxy icons for win32. Contributed by Jeff H.
1662 - In daemon mode, fd 0, 1 and 2 are bound to /dev/null.
1663 - Resolve localhost using whatever address family the operating
1664 system feels like. Previous betas would try to use IPv4 as this
1665 is what most users expect, but this didn't work reliably on
1667 - In the action lists on CGI pages, actions and their parameters are
1668 no longer separated with a space. The action file parser doesn't
1669 actually allow this and will throw an invalid syntax error if actions
1670 and parameters in the action files are separated. Not adding the
1671 spaces means copy and pasting CGI output into the action files works.
1672 - The default keep-alive timeout has been reduced to 5 seconds to work
1673 around hangs in clients that treat the proxy like any other host and
1674 stop allowing any new connections if the "maximum number of
1675 connections per host" is reached.
1676 - Several webbug URLs that look like they are leading to images are now
1677 blocked as image instead of empty documents. Doing the latter causes
1678 WebKit-based clients to show a "missing image" icon which may mess up
1680 - The no-such-domain template is used for DNS resolution
1681 problems with FEATURE_IPV6_SUPPORT enabled. Previously the
1682 connect-failed template was used. Reported by 'zebul666'.
1683 - Accepts quoted expiration dates even though RFC 2109 10.1.2
1684 doesn't seem to allow them. Reported anonymously.
1685 - Don't try to forget connections if connection sharing is disabled.
1686 This wasn't a real problem but caused an unnecessary log message.
1687 - The still undocumented --enable-extended-host-patterns configure
1688 option has a better description.
1689 - Fixed an error message that would claim a write to the server
1690 failed when actually writing to the client failed.
1691 - Log the crunch reason before trying to write to the client.
1692 The log is easier to read that way.
1693 - Several log messages about client connections also mention
1695 - handle-as-empty-document no longer depends on the image blocking
1697 - Privoxy-Log-Parser is roughly 40% faster in highlighting mode.
1698 - uagen, a Firefox User-Agent generator for Privoxy and Mozilla
1699 browsers has been imported and is available in the tarball's
1701 - The scripts in the tools directory treat unknown parameters
1704 *** Version 3.0.15 beta ***
1706 - In case of missing server data, no error message is send to the
1707 client if the request arrived on a reused connection. The client
1708 is then supposed to silently retry the request without bothering
1709 the user. This should significantly reduce the frequency of the
1710 "No server or forwarder data received" error message many users
1712 - More reliable detection of prematurely closed client sockets
1713 with keep-alive enabled.
1714 - FEATURE_CONNECTION_KEEP_ALIVE is decoupled from
1715 FEATURE_CONNECTION_SHARING and now available on
1717 - Improved handling of POST requests on reused connections.
1718 Should fix problems with stalled connections after submitting
1719 form data with some browser configurations.
1720 - Fixed various latency calculation issues.
1721 - Allows the client to pass NTLM authentication requests to a
1722 forwarding proxy. This was already assumed and hinted to work
1723 in 3.0.13 beta but actually didn't. Now it's confirmed to work
1724 with IE, Firefox and Chrome.
1725 Thanks to Francois Botha and Wan-Teh Chang
1726 - Fixed a calculation problem if receiving the server headers
1727 takes more than two reads, that could cause Privoxy to terminate
1728 the connection prematurely. Reported by Oliver.
1729 - Compiles again on platforms such as OpenBSD and systems
1730 using earlier glibc version that don't support AI_ADDRCONFIG.
1731 Anonymously submitted in #2872591.
1732 - A bunch of MS VC project files and Suse and Redhat RPM spec
1733 files have been removed as they were no longer maintained for
1735 - Overly long action lines are properly rejected with a proper
1736 error message. Previously they would be either rejected as
1737 invalid or cause a core dump through abort().
1738 - Already timed-out connections are no longer temporarily remembered.
1739 They weren't reused anyway, but wasted a socket slot.
1740 - len refers to the number of bytes actually read which might
1741 differ from the ones received. Adjust log messages accordingly.
1742 - The optional JavaScript on the CGI page uses encodeURIComponent()
1743 instead of escape() which doesn't encode all characters that matter.
1744 Anonymously reported in #2832722.
1745 - Fix gcc45 warnings in decompress_iob().
1746 - Various log message improvements.
1747 - Privoxy-Regression-Test supports redirect tests.
1748 - Privoxy-Log-Parser can gather some connection statistics.
1750 *** Version 3.0.14 beta ***
1752 - The latency is taken into account when evaluating whether or not to
1753 reuse a connection. This should significantly reduce the number of
1754 connections problems several users reported.
1755 - If the server doesn't specify how long the connection stays alive,
1756 Privoxy errs on the safe side of caution and assumes it's only a second.
1757 - The error pages for connection timeouts or missing server data use a
1758 Last-Modified date in the past. Retry attempts are detected and Privoxy
1759 removes the If-Modified-Since header to prevent the server from responding
1760 with status code 304 in which case the client would reuse the error message.
1761 - Setting keep-alive-timeout to 0 disables keep-alive support. Previously
1762 Privoxy would claim to allow persistence but not reuse the connection.
1763 - Pipelined requests are less likely to be mistaken for the request
1764 body of the previous request. Note that Privoxy still has no real
1765 pipeline support and will either serialize pipelined requests or
1766 drop them in which case the client has to resent them.
1767 - Fixed a crash on some Windows versions when header randomization
1768 is enabled and the date couldn't be parsed.
1769 - Privoxy's keep-alive timeout for the current connection is reduced
1770 to the one specified in the client's Keep-Alive header.
1771 - For HTTP/1.1 requests, Privoxy implies keep-alive support by not
1772 setting any Connection header instead of using 'Connection: keep-alive'.
1773 - If the socket isn't reusable, Privoxy doesn't temporarily waste
1774 a socket slot to remember the connection.
1775 - If keep-alive support is disabled but compiled in, the client's
1776 Keep-Alive header is removed.
1777 - Fixed a bug on mingw32 where downloading large files failed if
1778 keep-alive support was enabled.
1779 - Fixed a bug that (at least theoretically) could cause log
1780 timestamps to be occasionally off by about a second.
1781 - No Proxy-Connection header if added if there already is one.
1782 - The configure script respects the $PATH variable when searching
1785 *** Version 3.0.13 beta ***
1787 - Added IPv6 support. Thanks to Petr Pisar who not only provided
1788 the initial patch but also helped a lot with the integration.
1789 - Added client-side keep-alive support.
1790 - The connection sharing code is only used if the connection-sharing
1792 - The max-client-connections option has been added to restrict
1793 the number of client connections below a value enforced by
1794 the operating system.
1795 - Fixed a regression reintroduced in 3.0.12 that could cause
1796 crashes on mingw32 if header date randomization was enabled.
1797 - Compressed content with extra fields couldn't be decompressed
1798 and would get passed to the client unfiltered. This problem
1799 has only be detected through statical analysis with clang as
1800 nobody seems to be using extra fields anyway.
1801 - If the server resets the Connection after sending only the headers
1802 Privoxy forwards what it got to the client. Previously Privoxy
1803 would deliver an error message instead.
1804 - Error messages in case of connection timeouts use the right
1806 - If spawning a child to handle a request fails, the client
1807 gets an error message and Privoxy continues to listen for
1808 new requests right away.
1809 - The error messages in case of server-connection timeouts or
1810 prematurely closed server connections are now template-based.
1811 - If zlib support isn't compiled in, Privoxy no longer tries to
1812 filter compressed content unless explicitly asked to do so.
1813 - In case of connections that are denied based on ACL directives,
1814 the memory used for the client IP is no longer leaked.
1815 - Fixed another small memory leak if the client request times out
1816 while waiting for client headers other than the request line.
1817 - The client socket is kept open until the server socket has
1818 been marked as unused. This should increase the chances that
1819 the still-open connection will be reused for the client's next
1820 request to the same destination. Note that this only matters
1821 if connection-sharing is enabled.
1822 - A TODO list has been added to the source tarball to give potential
1823 volunteers a better idea of what the current goals are. Donations
1824 are still welcome too: http://www.privoxy.org/faq/general.html#DONATE
1826 *** Version 3.0.12 ***
1828 - The socket-timeout option now also works on platforms whose
1829 select() implementation modifies the timeout structure.
1830 Previously the timeout was triggered even if the connection
1831 didn't stall. Reported by cyberpatrol.
1832 - The Connection: keep-alive code properly deals with files
1833 larger than 2GB. Previously the connection was closed too
1835 - The content length for files above 2GB is logged correctly.
1836 - The user-manual directive on the show-status page links to
1837 the documentation location specified with the directive,
1838 not to the Privoxy website.
1839 - When running in daemon mode, Privoxy doesn't log anything
1840 to the console unless there are errors before the logfile
1842 - The show-status page prints warnings about invalid directives
1843 on the same line as the directives themselves.
1844 - Fixed several justified (but harmless) compiler warnings,
1845 mostly on 64 bit platforms.
1846 - The mingw32 version explicitly requests the default charset
1847 to prevent display problems with some fonts available on more
1848 recent Windows versions. Patch by Burberry.
1849 - The mingw32 version uses the Privoxy icon in the alt-tab
1850 windows. Patch by Burberry.
1851 - The timestamp and the thread id is omitted in the "Fatal error"
1852 message box on mingw32.
1853 - Fixed two related mingw32-only buffer overflows. Triggering
1854 them required control over the configuration file, therefore
1855 this isn't seen as a security issue.
1856 - In verbose mode, or if the new option --show-skipped-tests
1857 is used, Privoxy-Regression-Test logs skipped tests and the
1860 *** Version 3.0.11 ***
1862 - On most platforms, outgoing connections can be kept alive and
1863 reused if the server supports it. Whether or not this improves
1864 things depends on the connection.
1865 - When dropping privileges, membership in supplementary groups
1866 is given up as well. Not doing that can lead to Privoxy running
1867 with more rights than necessary and violates the principle of
1868 least privilege. Users of the --user option are advised to update.
1869 Thanks to Matthias Drochner for reporting the problem,
1870 providing the initial patch and testing the final version.
1871 - Passing invalid users or groups with the --user option
1872 didn't lead to program exit. Regression introduced in 3.0.7.
1873 - The match all section has been moved from default.action
1874 to a new file called match-all.action. As a result the
1875 default.action no longer needs to be touched by the user
1876 and can be safely overwritten by updates.
1877 - The standard.action file has been removed. Its content
1878 is now part of the default.action file.
1879 - In some situations the logged content length was slightly too low.
1880 - Crunched requests are logged with their own log level.
1881 If you used "debug 1" in the past, you'll probably want
1882 to additionally enable "debug 1024", otherwise only passed
1883 requests will be logged. If you only care about crunched
1884 requests, simply replace "debug 1" with "debug 1024".
1885 - The crunch reason has been moved to the beginning of the
1886 crunch message. For HTTP URLs, the protocol is logged as well.
1887 - Log messages are shortened by printing the thread id on its
1888 own (as opposed to putting it inside the string "Privoxy()").
1889 - The config option socket-timeout has been added to control
1890 the time Privoxy waits for data to arrive on a socket.
1891 - Support for remote toggling is controlled by the configure
1892 option --disable-toggle only. In previous versions it also
1893 depended on the action editor and thus configuring with the
1894 --disable-editor option would disable remote toggling support
1896 - Requests with invalid HTTP versions are rejected.
1897 - The template symbol @date@ can be used to include a date(1)-like
1898 time string. Initial patch submitted by Endre Szabo.
1899 - Responses from shoutcast servers are accepted again.
1900 Problem reported and fix suggested by Stefan.
1901 - The hide-forwarded-for-headers action has been replaced with
1902 the change-x-forwarded-for{} action which can also be used to
1903 add X-Forwarded-For headers. The latter functionality already
1904 existed in Privoxy versions prior to 3.0.7 but has been removed
1905 as it was often used unintentionally (by not using the
1906 hide-forwarded-for-headers action).
1907 - A "clear log" view option was added to the mingw32 version
1908 to clear out all of the lines in the Privoxy log window.
1909 Based on a patch submitted by T Ford.
1910 - The mingw32 version uses "critical sections" now, which prevents
1911 log message corruption under load. As a side effect, the
1912 "no thread-safe PRNG" warning could be removed as well.
1913 - The mingw32 version's task bar icon is crossed out and
1914 the color changed to gray if Privoxy is toggled off.
1916 *** Version 3.0.10 ***
1918 - Ordinary configuration file changes no longer cause program
1919 termination on OS/2 if the name of the logfile hasn't been
1920 changed as well. This regression probably crept in with the
1921 logging improvements in 3.0.7. Reported by Maynard.
1922 - The img-reorder filter is less likely to mess up JavaScript code in
1923 img tags. Problem and solution reported by Glenn Washburn in #2014552.
1924 - The source tar ball now includes Privoxy-Log-Parser,
1925 a syntax-highlighter for Privoxy logs. For fancy screenshots see:
1926 http://www.fabiankeil.de/sourcecode/privoxy-log-parser/
1927 Documentation is available through perldoc(1).
1929 *** Version 3.0.9 beta ***
1931 - Added SOCKS5 support (with address resolution done by
1932 the SOCKS5 server). Patch provided by Eric M. Hopper.
1933 - The "blocked" CGI pages include a block reason that was
1934 provided as argument to the last-applying block action.
1935 - If enable-edit-actions is disabled (the default since 3.0.7 beta)
1936 the show-status page hides the edit buttons and explains why.
1937 Previously the user would get the "this feature has been disabled"
1938 message after using the edit button.
1939 - Forbidden CONNECT requests are treated like blocks by default.
1940 The now-pointless treat-forbidden-connects-like-blocks action
1942 - Not enabling limit-connect now allows CONNECT requests to all ports.
1943 In previous versions it would only allow CONNECT requests to port 443.
1944 Use +limit-connect{443} if you think you need the old default behaviour.
1945 - The CGI editor gets turned off after three edit requests with invalid
1946 file modification timestamps. This makes life harder for attackers
1947 who can leverage browser bugs to send fake Referers and intend to
1948 brute-force edit URLs.
1949 - Action settings for multiple patterns in the same section are
1950 shared in memory. As a result these sections take up less space
1951 (and are loaded slightly faster). Problem reported by Franz Schwartau.
1952 - Linear white space in HTTP headers will be normalized to single
1953 spaces before parsing the header's content, headers split across
1954 multiple lines get merged first. This should prevent problems like:
1955 * letting the session-cookies-only action slip
1956 some Cookies through unmodified,
1957 * only suppressing the first line of a header,
1958 thus creating an invalid one, and
1959 * to incorrectly block headers with valid timestamps
1960 that weren't properly recognized.
1961 Headers that could trigger these problems are unlikely to appear
1962 in "normal" web traffic, but could be intentionally generated to
1963 fool some of Privoxy's header parsers.
1964 - Host information is gathered outside the main thread so it's less
1965 likely to delay other incoming connections if the host is misconfigured.
1966 - New config option "hostname" to use a hostname other than
1967 the one returned by the operating system. Useful to speed-up responses
1968 for CGI requests on misconfigured systems. Requested by Max Khon.
1969 - The CGI editor supports the "disable all filters of this type"
1970 directives "-client-header-filter", "-server-header-filter",
1971 "-client-header-tagger" and "-server-header-tagger".
1972 - Fixed false-positives with the link-by-url filter and URLs that
1973 contain the pattern "/jump/".
1974 - The less-download-windows filter no longer messes
1975 "Content-Type: application/x-shockwave-flash" headers up.
1976 - In the show-url-info page's "Final results" section active and
1977 inactive actions are listed separately. Patch provided by Lee.
1978 - The GNUmakefile supports the DESTDIR variable. Patch for
1979 the install target submitted by Radoslaw Zielinski.
1980 - Embedding the content of configuration files in the show-status
1981 page is significantly faster now. For a largish action file (1 MB)
1982 a speedup of about 2450 times has been measured. This is mostly
1983 interesting if you are using large action files or regularly use
1984 Privoxy-Regression-Test while running Privoxy through Valgrind,
1985 for stock configuration files it doesn't really matter.
1986 - If zlib support is unavailable and there are content
1987 filters active but the prevent-compression action is disabled,
1988 the show-url-info page includes a warning that compression
1989 might prevent filtering.
1990 - The show-url-info page provides an OpenSearch Description that
1991 allows to access the page through browser search plugins.
1992 - Custom client-header filters that rewrite the request line
1993 incorrectly no longer cause Privoxy to crash. Reported by din_a4.
1994 - The obsolete kill-popups action has been removed as the
1995 PCRS-based popup filters can do the same and are slightly
1997 - The inspect-jpegs action has been removed.
1998 - The send-wafer and send-vanilla-wafer actions have been removed.
1999 They weren't particular useful and their behaviour could be emulated
2000 with add-header anyway.
2001 - Privoxy-Regression-Test has been significantly improved.
2002 - Most sections in the default.action file contain tests for
2003 Privoxy-Regression-Test to verify that they are working as intended.
2004 - Parts of Privoxy have been refactored to increase maintainability.
2005 - Building with zlib (if available) is done by default.
2007 *** Version 3.0.8 ***
2009 - Fixed a small memory leak when listen-address only specifies the port.
2010 - The source tar balls now include Privoxy-Regression-Test which
2011 (upon other things) can be used to automatically detect some
2012 packaging problems. Packagers are welcome to give it a try.
2013 - Reverted a change in 3.0.7 that caused path patterns to be checked
2014 even if the host pattern match already failed. While this doesn't
2015 noticeable affect the performance, it makes it less likely to run
2016 out of stack space with overly-complex path patterns the user might
2018 - Updated the msn, yahoo and google filters to work as advertised again.
2019 - The warning message shown by the show-status CGI page is easier to
2020 understand. Previously it wasn't clear that the error message
2021 is shown below the invalid directive. (Reported by Lee)
2022 - When regenerating Content-Disposition headers the more common
2023 spelling is used for the name. Previously it was written without caps.
2024 - Less confusing log message if the content type isn't overwritten
2025 because force-text-type wasn't used but the old type doesn't look
2026 like content that would be filtered normally.
2027 - Better log messages if the user tries to execute filters that
2029 - Treat the non-standard Request-Range headers like standard range
2030 headers and suppress them if content filtering is enabled.
2031 - Prevent the log messages for CONNECT requests to unacceptable
2032 ports from printing the limit-connect argument as [null] if
2033 limit-connect hasn't been explicitly enabled.
2034 - Don't disable the mingw32 log window if the logfile directive
2035 isn't used. While it was an intentional change in 3.0.7 at least
2036 one user perceived it as a regression and the same effect can
2037 be achieved by disabling all debug directives.
2038 - Fixed two minor problems related to the win32 build process: a css
2039 file was not being in the installer and the trustfile comment in the
2040 config.txt referenced a nonexisting file
2041 - Minor documentation fixes.
2043 *** Version 3.0.7 beta ***
2045 - Added zlib support to filter content with gzip and deflate
2046 encoding. (Patch provided by Wil Mahan)
2047 - Dedicated filters and actions are used for header filtering.
2048 "filter-client-headers" and "filter-client-headers" are no longer
2049 supported, use server-header-filter{} and client-header-filter{}
2051 - Tags can be used to change actions based on HTTP headers.
2052 - New server-header filter: less-download-windows.
2053 - New client-header taggers: css-requests, image-requests,
2054 client-ip-address, http-method, allow-post, complete-url,
2055 user-agent and privoxy-control.
2056 - New server-header taggers: content-type and privoxy-control.
2057 - The forward-override{} action allows to change the forwarding
2058 settings through the action files, for example based on client
2059 headers like the User-Agent, or the request origin.
2060 - Socks errors are no longer handled by the CGI page for
2061 DNS resolution failures.
2062 - CGI pages use favicons to signal whether they are error
2063 or control pages. This is useful if you rely heavily on
2065 - The show-url-info CGI page shows the forwarding settings.
2066 - "Crunch!" log messages (used when Privoxy answers requests
2067 by itself) now also contain the reason.
2068 - Allow to rewrite the request destination behind the client's back.
2069 - Fix socks requests on big-endian platforms. Patch provided by Song Weijia.
2070 - Fixes possible deadlocks and crashes on OpenBSD.
2071 Patch provided by Ralf Horstmann.
2072 - The CGI action editor allows to edit actionfiles with previously
2073 forbidden characters like dots.
2074 - New trust entries are saved with a comment that contains the
2075 trusted referring URL (Suggested by Daniel Griscom).
2076 - Filter descriptions are HTML encoded automatically.
2077 - New config option "split-large-forms" to work
2078 around a browser bug that caused IE6 and IE7 to ignore
2079 the Submit button on the edit-actions-for-url CGI page.
2080 - New config option "allow-cgi-request-crunching" to allow
2081 requests for Privoxy's CGI pages to be blocked, redirected
2082 or (un)trusted like ordinary requests.
2083 - Empty filter files no longer interrupt the filtering process
2084 prematurely and are correctly listed on the show-status CGI page.
2085 - New config option "accept-intercepted-requests" to combine
2086 Privoxy with any packet filter to build an intercepting proxy
2087 for HTTP/1.1 requests (and for HTTP/1.0 requests with Host header set).
2088 - fast-redirects{} catch redirects to https URLs as well.
2089 - redirect{s@foo@bar@} can be used to redirect to a rewritten
2090 version of the original URL.
2091 - Trap unsupported gopher proxy requests.
2092 - Fixed a bug in the User Manual delivery on Windows
2093 (mingw32 only). Images now show up correctly and HTML
2094 pages are no longer padded with garbage data.
2095 - Fixed several minor memory leaks, most of them discovered with Valgrind.
2096 - Only unlink the pidfile if it's actually used.
2097 - Retries after connection problems with forced requests
2098 aren't blocked again.
2099 - On Unix SIGABRT causes a core dump as expected and is no
2100 longer treated as normal shutdown signal.
2101 - The "access denied" CGI page is more descriptive and
2102 allows retries to circumvent the referrer check.
2103 - Updated PCRS to handle unexpected PCRE errors properly.
2104 Fixed crashes that could occur if Privoxy was build
2105 with external PCRE versions newer than Privoxy's internal
2106 one. (Reported by Chung-chieh Shan)
2107 - Fixed crashes with null bytes in PCRS replacement strings
2108 (Patch provided by Felix Gröbert).
2109 - Fixed crashes with header time randomization on mingw32.
2110 - The CGI style sheet is no longer delivered if the referring
2111 page isn't a Privoxy CGI page. This prevents a JavaScript-based
2112 Privoxy detection "attack". Note that detecting Privoxy is
2113 still possible through other ways and Privoxy was never intended
2114 to be invisible anyway.
2115 - Added support for AmigaOS 4, fixed build for AmigaOS 3.x.
2116 - The show-url-info CGI page displays a warning if Privoxy
2117 is currently toggled off.
2118 - The show-status CGI page suppresses the edit button
2119 for action files if Privoxy has no write access.
2120 - Most CGI error pages react properly to HEAD requests.
2121 - Requests with RFC 3253 HTTP methods (used by Subversion)
2122 are accepted. (Patch provided by Petr Kadlec)
2123 - New config option "templdir" to change the location
2124 of the CGI templates to make sure customized templates
2126 - Better handling of "HTTP/1.1 100 Continue" responses.
2127 - The background of the PNG pattern is transparent.
2128 - Fixed XML syntax errors caused by banners-by-size and banners-by-url.
2129 - Fixed crashes and possible action file corruptions
2130 when lines containing hashes are written through the CGI editor.
2131 - Supports dynamic filters which can contain variables.
2132 - Supports tags to change the actions based on client or server headers.
2133 - Incorrect actions are logged before program termination.
2134 - The "actionsfile" syntax in the configuration file is consistent
2135 with the rest of the configuration options and requires the
2136 whole file name. This is an incompatible change, if you use
2137 an old configuration file you might have to append ".action"
2138 to your "actionsfile" directives.
2139 - With the configuration file option "enforce-blocks" the
2140 "go there anyway" mechanism can be disabled without recompiling
2142 - More precise error messages in case of incorrect acl syntax.
2143 - Logs a warning if filtering is enabled but impossible due
2144 to lack of zlib support or use of the prevent-compression action.
2145 - Less noisy handling of Cookie:" and "Connection:" headers.
2146 - Improved error messages in case of connection problems.
2147 - Fix a command-line-parsing bug that was introduced before 3.0.5
2148 beta and caused Privoxy to treat the last argument as configuration
2149 file if no configuration file was specified.
2150 - Treat unknown command line options as fatal errors instead
2151 of silently ignoring them.
2152 - Use string functions with length checks more often.
2153 - Don't log CONNECT requests twice.
2154 - Allow to log the source address for ACL-related connection drops.
2155 - Don't ignore applying filters if the server didn't
2156 specify a Content-Type. Bug reported by Amuro Namie.
2157 - Rejected CONNECT requests are logged with log level info
2158 (enabled by default) and the reason for the block.
2159 - New command line option "--pre-chroot-nslookup hostname" to
2160 intialize the resolver library before chroot'ing. On some systems this
2161 reduces the number of files that must be copied into the chroot tree.
2162 (Patch provided by Stephen Gildea)
2163 - Fix a long-standing memory corruption bug that could cause
2164 Privoxy to overwrite a single byte in memory it didn't explicitly
2165 allocate (but that probably was allocated anyway due to bucket size).
2166 - Send template-based CGI pages as HTTP/1.1 unless the client
2168 - Let the first line in connection established responses
2169 end in \r\n as required by RFC1945. Reported by Bert van Leeuwen.
2170 - If no log file has been specified, disable logging instead of logging
2172 - Don't block stderr when in daemon mode.
2173 - Ignore missing zero-chunks when filtering chunk-encoded content.
2174 Earlier Privoxy versions would buffer and then forward the content
2175 unmodified which caused some browsers to simply show empty pages.
2176 - Fix double free in cgi_edit_actions_list(). Reported by Venustech AD-LAB.
2177 - The code to add X-Forwarded-For headers when the hide-forwarded-for-headers
2178 action isn't being used has been removed.
2179 - Fixed trustfile feature which previously didn't work without FEATURE_TOGGLE.
2181 - Minor code clean-ups, filter and action file updates.
2182 (Some of them reported by Davide Alberani, Markus Elfring,
2183 Stefan Huehner and Adam Piggott)
2185 *** Version 3.0.6 ***
2187 - New content filters: no-ping, google, msn, yahoo and blogspot.
2188 - New header filters: x-httpd-php-to-html, html-to-xml, xml-to-html
2189 and hide-tor-exit-notation.
2190 - The special header "X-Filter: No" now disables header filtering as well.
2191 - Improved the filters img-reorder, js-annoyances, webbugs,
2192 banners-by-size, banners-by-link and ie-exploits to make them
2193 less likely to break anything.
2194 - Removed outdated URL patterns in default.action and added new ones.
2195 - Added redirection from http://p.p/user-manual to http://p.p/user-manual/
2196 - Changed webinterface default values for hide-user-agent, hide-referrer
2197 and set-image-blocker.
2199 *** Version 3.0.5 beta ***
2201 - Windows version can be installed/started as a service.
2202 - Windows icon stays blue when Privoxy is idle, green when busy.
2203 - Integrated Fabian Keil's extensive patch. See:
2204 http://www.fabiankeil.de/sourcecode/privoxy/. Includes the
2205 following new or significantly improved actions (among many
2206 other improvements):
2208 content-type-overwrite{}
2209 crunch-client-header{string}
2210 crunch-if-none-match
2211 crunch-server-header{string}
2212 fast-redirects{check-decoded-url}
2213 filter-client-headers
2214 filter-server-headers
2216 handle-as-empty-document
2217 hide-accept-language{}
2218 hide-content-disposition{}
2219 hide-if-modified-since
2220 hide-referrer{conditional-block}
2221 overwrite-last-modified{}
2223 treat-forbidden-connects-like-blocks
2225 - Standard-compliant clients are prevented from displaying cached
2226 copies of Privoxy's error messages after the cause of the problem
2228 - Improved DNS error handling.
2229 - Multiple filter files can now be specified in config.
2230 - Added jpeg filtering to defend against MS jpeg vulnerability MS04-028
2231 with the new inspect-jpegs action.
2232 - Removed the "arbitrary" 1000 filter limit - addresses tracker #911950
2233 - Thanks to Jindrich Makovicka for a race condition fix for the log
2234 file. The race condition remains for non-pthread implementations.
2235 Reference patch #1175720. Various other logging enhancements.
2236 - A pile of assorted bug fixes, memory leaks, enhancements, etc.
2237 - Moved Actions file reporting mechanism to SF tracker.
2238 - Two new options for config: enable-remote-http-toggle and
2239 forwarded-connect-retries.
2240 - Trap unsupported FTP requests.
2241 - Let text/xml be filtered.
2242 - Numerous updates to default.action
2243 - Increase the compiled in limit of trusted referrers from 64 to 512
2244 (for trustfile users).
2246 *** Version 3.0.3 ***
2248 - Fixed yet another two memory leaks. Process growth seems stopped now.
2249 - Further tightened security against malicious toggle-off links.
2250 - Excluded text/plain MIME types from filtering. This fixes a
2251 couple of client-crashing, download corruption and
2252 Privoxy performance issues, whose root cause lies in
2253 web servers labelling content of unknown type as text/plain.
2254 - Assorted fixes for POSIX compliance, signal handling, graceful
2255 termination, compiler warnings, OSX support, Win32 systray,
2256 error logging, hostname wildcards, correct detection of NetBSD.
2257 - Workarounds for client (iTunes etc) and server (PHP < 4.2.3) bugs
2258 including the notorious "blank page" problem.
2259 - Various filter improvements; most notably the unsolicited-popups
2260 filter became less destructive
2261 - Major revamp of the actions file
2263 *** Version 3.0.2 ***
2265 - Fixed two memory leaks, one serious
2266 - Fixed bug in pcrs which could cause crashes with user-defined filters
2267 - Fixed bug in domain name matching
2268 - Assorted small fixes (Win32 menu, CGI URL editor, ..)
2269 - Added basic support for the OPTIONS and TRACE http methods
2270 - Added workaround for Bug in Mac OSX that made Privoxy crash occasionally
2271 - Refined the default action file through >400 items of user feedback
2273 - Assorted refinements, optimizations and fixes in the js-annoyances,
2274 img-reorder, banners-by-size, banners-by-link, webbugs, refresh-tags,
2275 html-annoyances, content-cookies and fun filters
2276 - Replaced filter "popups" by choice between two modes:
2277 - "unsolicited-popups" tries to catch only the unsolicited ones
2278 - "all-popups" tries to kill them all (as before)
2279 - New filter "tiny-textforms" Help those tiny or hard-wrap textareas.
2280 - New filter "jumping-windows" that prevents windows from resizing
2281 and moving themselves
2282 - New filter "demoronizer" which fixes MS's abuse of std charsets
2283 (common cases anyway).
2284 - Replaced "nimda" with more general "ie-exploits" filter in which
2285 all filters for exploits shall be collected
2286 - Improved cookie logging
2287 - Rewrote make install target. Added uninstall and install-strip
2289 - Fixed a potential (application-level, NOT OS-level!) security
2290 problem involving remote toggling and action file manipulation
2291 by mailicious websites.
2292 - Added ability to chroot (thanks to Sviatoslav Sviridov)
2293 - Added more action aliases for prehistoric action names
2294 - Add Slackware support to Makefile.
2298 - Fixed Windows startmenu items, log window and tray icon menus.
2299 - Added warning for bogus install target
2300 - Added quicktime-kioskmode filter and improved frameset-borders
2301 - Updated default.action based on latest feedback
2302 - New PDF doc build process
2303 - Add a user contrib module to cvs:
2304 http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/ijbswa/contrib/
2306 *** Version 2.9.18 ***
2308 - Added workaround for IE bug that broke CGI interface
2309 - Bugfix: String actions now reliably editable through CGI interface
2310 - Three filters fixed (again!)
2311 - Assorted small fixes and doc enhancements
2313 *** Version 2.9.16 ***
2315 - Major revamp of default.action to get rid of years of cruft.
2316 - Same for default.filter
2317 - Re-design and major improvements to the CGI editor interface.

2320 - Better memory and CPU optimization.
2321 - Add Conectiva Linux package.
2322 - user-manual directive added to config for help links from within CGI
2324 - Multiple actions files can now be specified in config.
2325 - Actions files are changed to: default.action, standard.action, and
2326 user.action. user.action is for personal/local configuration.
2327 - The usual many small and miscellaneous bug and security fixes.
2329 *** Version 2.9.14 beta ***

2336 - Various tweaks for actions file to get ready for stable 3.0
2337 - Included a 'Bookmarklet' and PHP scripts for reporting actions file
2338 problems via web interface at privoxy.org. Accessed via internal CGIs.
2339 - Include cgi-style.css for templates.
2340 - #include mechansim for common text in templates
2341 - Various other minor fixes.
2343 *** Version 2.9.13 beta ***
2345 - *NEWS*: The project has been renamed to Privoxy! The new name is
2346 reflected throughout (file locations, etc).
2347 - ijb.action is now default.action. re_filterfile is now

2361 - Win32 command line fix ups.
2362 - re_filterfile now has modular sections that can be activated on a
2363 per site basis. Some new goodies there too.
2364 - +filter now takes arguments to match FILTER sections in re_filterfile
2365 for even more flexibility.
2366 - Added a new image blocker option: +image-blocker{pattern}, which
2367 displays a checkerboard patthern and scales better than the logo.
2368 - PNG images will be used in place of GIF for JB built-in images
2369 if configured with --enable-no-gif.

2383 - Signal handling cleanups (*nix).
2384 - CGI actions editor improvements and fixes.

2406 - A web-based editor for the actions file is included (go to http://i.j.b/).
2407 - Web-based toggle IJB on/off support.
2408 - Cookie handling has changed - the new +no-cookies-keep feature is now the

2417 - Many other minor bugfixes
2418 - Start a ChangeLog :)
2422 *** Version 2.9.3 pre-Alpha Changes ***
2424 - Amiga support (completely untested by me - I don't have an Amiga)
2425 - "tinygif 3" support (redirects blocked images to a specified URL, so
2426 the browser doesn't have to load and cache many copies of the same
2428 - one case where there were both local and global "referrer" variables
2429 (yuck!) clarified by renaming the local one to "refer".
2430 - Fixed some places where close() was used instead of close_socket().
2431 Thanks to Jörg Strohmayer (joergs at users.sourceforge.net) for these.
2432 - Temporary hack to get FORCE_LOAD to work with IE. I just lowercased the
2433 FORCE_LOAD_PREFIX. Needs fixing properly.
2434 - Most URLs hardcoded into Junkbuster were changed to go through a script
2435 e.g. http://ijbswa.sourceforge.net/redirect.php?v=2.9.3&to=faq
2436 The only other URLs left are the GNU GPL:
2437 http://www.fsf.org/copyleft/gpl.html
2439 http://ijbswa.sourceforge.net/
2440 ... and various URLs which will be intercepted by Junkbuster anyway.
2441 TODO: Still need to do something with the URLs in Junkbuster Corp's
2442 copyright/trademark notice on the bottom of the show-proxy-args page.
2443 - PCRE or GNU Regex is now a #define option.
2446 *** Version 2.9.2 pre-Alpha Changes ***
2448 - Andreas applied the latest version of the FORCE patch.
2451 *** Version 2.9.1 pre-Alpha Changes ***
2453 - in parsers.c, fixed two #ifdef FORCE to #ifdef FORCE_LOAD
2454 (BTW: I think FORCE is precise enough, since loading remote
2455 data is the whole purpose of a proxy..)
2456 - Set the FORCE_PREFIX (back) to 'IJB-FORCE-LOAD-'. While 'noijb.'
2457 is more elegant and looks like a hostname in the URL, it doesn't
2458 make clear to the inexperienced user that the proxy is bypassed. It
2459 also has a higher name collision risk.
2460 - Filled in the function header templates for my functions in
2461 parsers.c (again). They obviously got lost in our current
2463 - Cut the credit for the §-referrer-option from the config file,
2464 that Stefan had placed there.
2465 - Improved the re_filterfile
2468 *** Version 2.9.0 pre-Alpha Changes ***
2470 - Now use PCRE, not GNU REGEX. I have not yet had chance to check the
2471 syntax of the block/image/cookie file to ensure that they match what
2472 is expected - however they seem to work.
2473 - Replaced "configure" script with one generated by "autoconf". Also
2474 use a header "config.h" (was ijbconfig.h in my previous release) for
2475 the #defines. "config.h" is now generated with "autoheader" from
2476 "acconfig.h" and "configure.in". (Note that to install you do not
2477 need autoconf or autoheader - just run "./configure".)
2478 To see command-line options, run "./configure --help".
2479 This is my first ever autoconf script, so it has some rough edges
2480 (how PCRE is handled is the roughest).
2481 - Error logging code replaced with new module errlog.c, based on the
2482 one from JunkbusterMT (but with the threading code removed).
2483 - Most of Rodney's 0.21 and 0.21A patches applied. (Marked *). I did not
2484 apply all of these, since I had already independently done conditional
2485 popup file, conditional image file, and integration of popup code.
2486 - ACL, Jar and trust files conditionally compiled.
2487 - New source file headers.
2488 - Various cosmetic changes. (But I have not consistently ordered the
2489 config files - I think that's worthwhile, but it's 1am and I want to
2491 - RCS tags on .h files.
2492 - RCS tags are const char[] rather than const char *. (Saves 4 bytes
2494 - VC++ project files renamed to vc_junkbuster.*.
2495 - show-proxy-args now shows status of all conditionals, not just REGEX
2496 - Various functions moved around. Most notably all the system-specific
2497 sockets code which was spread between jcc.c, bind.c, and connect.c,
2498 has been moved to "jbsockets.c". The non-system-specific code from
2499 connect.c and socks4.c has been movet to "gateway.c". Also, the
2500 config file loader and the global variables it writes to have been
2501 moved to "loadcfg.c". (Maybe this should go into loaders.c?)
2502 And candidate for the "worst filename ever" award is "miscutil.c",
2503 which contains, well, miscellaneous utility functions like zalloc.
2504 (Suggestions for a better name for this file are welcome!)
2505 - Loaders now use a common function to read a line and skip comments,
2506 and this function also stores the proxy_args.
2507 - Added ./junkbuster --help (Not for Win32 GUI)
2508 - Added ./junkbuster --version (Not for Win32 GUI)
2509 - Win32 resources are now all marked as "U.S. English", rather than
2510 being a mix of "U.S. English", "U.K. English" and "Irish English".
2511 - Version number changes to 2.9.0
