4 *** Version 3.0.22 stable ***
7 - Actually show the FORCE_PREFIX value on the show-status page
8 - Properly deal with Keep-Alive headers with timeout= parameters
9 If the timeout still can't be parsed, use the configured
10 timeout instead of preventing the client from keeping the
11 connection alive. Fixes #3615312/#870 reported by Bernard Guillot.
12 - Not using any filter files no longer results in warning messages
13 unless an action file is referencing header taggers or filters.
14 Reported by Stefan Kurtz in #3614835.
15 - A couple of additional bugs were discovered by Coverity Scan.
16 The changes that are not expected to be user visible are not
17 explicitly mentioned here, for details please have a look at
20 - General improvements:
21 -Introduced negative tag patterns NO-REQUEST-TAG and NO-RESPONSE-TAG
22 They apply if no matching tag is found after parsing client
24 - Add support for external filters which allow to process the
25 response body with a script or program written in any language
26 the platform supports. External filters are enabled with
27 +external-filter{} after they have been defined in one of the
28 filter files with a header line starting with "EXTERNAL-FILTER:".
29 External filter support is experimental, not compiled by default
30 and not expected to work on all platforms.
31 - Add support for the 'PATCH' method as defined in RFC5789
32 - Reject requests with unsupported Expect header values
33 Fixes a couple of Co-Advisor tests.
34 - Normalize the HTTP-version in forwarded requests and responses.
35 This is an explicit RFC 2616 MUST and RFC 7230 mandates
36 that intermediaries send their own HTTP-version in forwarded
38 - Change declared template file encoding to UTF-8.
39 The files already used a subset of UTF-8 anyway and changing
40 the declaration allows to properly display UTF-8 characters
41 used in the action files.
42 This change may require existing action files with ISO-8859-1
43 characters that aren't valid UTF-8 to be converted to UTF-8.
44 Requested by Sam Chen in #582.
45 - Do not pass rejected keep-alive timeouts to the server. It might
46 not have caused any problems (we know of), but doing the right
47 thing shouldn't hurt either.
48 - Let log_error() use its own buffer size #define
49 to make changing the log buffer size slightly less inconvenient.
50 - Turned single-threaded into a "proper" toggle directive with arguments.
51 - CGI templates no longer enforce new windows for some links.
52 - Remove an undocumented workaround (HOST header removal) for
53 an Apple iTunes bug that according to #729900 got fixed in 2003.
55 - Action file improvements:
56 - The pattern 'promotions.' is no longer being blocked.
57 Reported by rakista in #3608540.
58 - Disable fast-redirects for .microsofttranslator.com/
59 - Disable filter{banners-by-size} for .dgb-tagungszentren.de/
60 - Add adn.speedtest.net as a site-specific unblocker.
61 Support request #3612908.
62 - Disable filter{banners-by-size} for creativecommons.org/
63 - Block requests to data.gosquared.com/. Reported by cbug in #3613653.
64 - Unblock .conrad./newsletter/. Reported by David Bo in #3614238.
65 - Unblock .bundestag.de/.
66 - Unblock .rote-hilfe.de/.
67 - Disable fast-redirects for .facebook.com/plugins/like.php.
68 - Unblock Stackexchange popup URLs that aren't used to serve ads.
69 Reported by David Wagner in #3615179.
70 - Disable fast-redirects for creativecommons.org/.
71 - Unblock .stopwatchingus.info/.
72 - Block requests for .adcash.com/script/.
73 Reported by Tyrexionibus in #3615289.
74 - Disable HTML filters if the response was tagged as JavaScript.
75 Filtering JavaScript code with filters intended to deal with HTML
76 is usually a waste of time and, more importantly, may break stuff.
77 - Use a custom redirect{} for .washingtonpost.com/wp-apps/imrs\.php\?src=
78 Previously enabling the 'Advanced' settings (or manually enabling
79 +fast-redirects{}) prevented some images from being loaded properly.
80 - Unblock "adina*." Fixes #919 reported by Morton A. Goldberg.
82 - Unblock 'adele*.'. Reported by Adele Lime in #1663.
84 - Filter file improvements & bug fixes:
85 - Decrease the chances that js-annoyances creates invalid JavaScript.
86 Submitted by John McGowan on ijbswa-users@.
87 - Let the msn filter hide 'related' ads again
88 - Remove a stray '1' in the 'html-annoyances' filter
89 - Prevent img-reorder from messing up img tags with empty src attributes
90 Fixes #880 reported by Duncan.
92 - Documentation improvements:
93 - Updated the 'Would you like to donate?' section.
94 - Note that invalid forward-override{} parameter syntax isn't
95 detected until the parameter is used.
96 - Add another +redirect{} example: a shortcut for illumos bugs.
97 - Make it more obvious that many operating systems support log
98 rotation out of the box
99 - Fixed dead links. Reported by Mark Nelson in #3614557.
100 - Rephrased the 'Why is the configuration so complicated?' answer
101 to be slightly less condescending. Anonymously suggested in #3615122.
102 - Be more explicit about accept-intercepted-requests's lack of MITM support
103 - Make 'demoronizer' FAQ entries more generic
104 - Add an example hostname to the --pre-chroot-nslookup description
105 - Add an example for a host pattern that matches an IP address
106 - Rename the 'domain pattern' to 'host pattern' as it may contain IP addresses as well
107 - Recommend forward-socks5t when using Tor
108 It seems to work fine and modifying the Tor configuration
109 to profit from it hasn't been necessary for a while now.
110 - Add another redirect{} example to stress that redirect loops can and should be avoided
111 - The usual spelling and grammar fixes. Parts of them were
112 reported by Reuben Thomas in #3615276.
113 - Mention the PCRS option letters T and D in the filter section
114 - Clarify that handle-as-empty-doc-returns-ok is still useful
115 and will not be removed without replacement
116 - Note that security issues shouldn't be reported using the bug tracker
117 - Clarify what Privoxy does if both +block{} and +redirect{} apply
118 - Removed the obsolete bookmarklets section.
120 - Build system improvements
121 - Let --with-group properly deal with secondary groups
122 Patch submitted by Anatoly Arzhnikov in #3615187.
123 - Fix web-actions target
124 - Add a web-faq target that only updates the FAQ on the webserver
125 - Remove already-commented-out non-portable DOSFILTER alternatives
126 - Remove the obsolete targets dok-put and dok-get
127 - Add a sf-shell target
129 *** Version 3.0.21 stable ***
132 - On POSIX-like platforms, network sockets with file descriptor
133 values above FD_SETSIZE are properly rejected. Previously they
134 could cause memory corruption in configurations that allowed
135 the limit to be reached.
136 - Proxy authentication headers are removed unless the new directive
137 enable-proxy-authentication-forwarding is used. Forwarding the
138 headers potentially allows malicious sites to trick the user
139 into providing them with login information.
140 Reported by Chris John Riley.
141 - Compiles on OS/2 again now that unistd.h is only included
142 on platforms that have it.
144 - General improvements:
145 - The show-status page shows the FEATURE_STRPTIME_SANITY_CHECKS status.
146 - A couple of assert()s that could theoretically dereference
147 NULL pointers in debug builds have been relocated.
148 - Added an LSB info block to the generic start script.
149 Based on a patch from Natxo Asenjo.
150 - The max-client-connections default has been changed to 128
151 which should be more than enough for most setups.
153 - Action file improvements:
154 - Block rover.ebay./ar.*\&adtype= instead of "/.*\&adtype=" which
155 caused too man false positives.
156 Reported by u302320 in #360284, additional feedback from Adam Piggott.
157 - Unblock '.advrider.com/' and '/.*ADVrider'.
158 Anonymously reported in #3603636.
159 - Stop blocking '/js/slider\.js'.
160 Reported by Adam Piggott in #3606635 and _lvm in #2791160.
162 - Filter file improvements:
163 - Added an iframes filter.
165 - Documentation improvements:
166 - The whole GPLv2 text is included in the user manual now,
167 so Privoxy can serve it itself and the user can read it
168 without having to wade through GPLv3 ads first.
169 - Properly numbered and underlined a couple of section titles
170 in the config that where previously overlooked due to a flaw
171 in the conversion script. Reported by Ralf Jungblut.
172 - Improved the support instruction to hopefully make it harder to
173 unintentionally provide insufficient information when requesting
174 support. Previously it wasn't obvious that the information we need
175 in bug reports is usually also required in support requests.
176 - Removed documentation about packages that haven't been provided
179 - Privoxy-Regression-Test:
180 - Only log the test number when not running in verbose mode
181 The position of the test is rarely relevant and it previously
182 wasn't exactly obvious which one of the numbers was useful to
183 repeat the test with --test-number.
185 - GNUmakefile improvements:
186 - Factor generate-config-file out of config-file to make testing
188 - The clean target now also takes care of patch leftovers.
190 *** Version 3.0.20 beta ***
193 - Client sockets are now properly shutdown and drained before being
194 closed. This fixes page truncation issues with clients that aggressively
195 pipeline data on platforms that otherwise discard already written data.
196 The issue mainly affected Opera users and was initially reported
197 by Kevin in #3464439, szotsaki provided additional information to track
199 - Fix latency calculation for shared connections (disabled by default).
200 It was broken since their introduction in 2009. The calculated latency
201 for most connections would be 0 in which case the timeout detection
202 failed to account for the real latency.
203 - Reject URLs with invalid port. Previously they were parsed incorrectly and
204 characters between the port number and the first slash were silently
205 dropped as shown by curl test 187.
206 - The default-server-timeout and socket-timeout directives accept 0 as
208 - Fix a race condition on Windows that could cause Privoxy to become
209 unresponsive after toggling it on or off through the taskbar icon.
210 Reported by Tim H. in #3525694.
211 - Fix the compilation on Windows when configured without IPv6 support.
212 - Fix an assertion that could cause debug builds to abort() in case of
213 socks5 connection failures with "debug 2" enabled.
214 - Fix an assertion that could cause debug builds to abort() if a filter
215 contained nul bytes in the replacement text.
217 - General improvements:
218 - Significantly improved keep-alive support for both client and server
220 - New debug log level 65536 which logs all actions that were applied to
222 - New directive client-header-order to forward client headers in a
223 different order than the one in which they arrived.
224 - New directive tolerate-pipelining to allow client-side pipelining.
225 If enabled (3.0.20 beta enables it by default), Privoxy will keep
226 pipelined client requests around to deal with them once the current
227 request has been served.
228 - New --config-test option to let Privoxy exit after checking whether or not
229 the configuration seems valid. The limitations noted in TODO #22 and #23
230 still apply. Based on a patch by Ramkumar Chinchani.
231 - New limit-cookie-lifetime{} action to let cookies expire before the end
232 of the session. Suggested by Rick Sykes in #1049575.
233 - Increase the hard-coded maximum number of actions and filter files from
234 10 to 30 (each). It doesn't significantly affect Privoxy's memory usage
235 and recompiling wasn't an option for all Privoxy users that reached the
237 - Add support for chunk-encoded client request bodies. Previously
238 chunk-encoded request bodies weren't guaranteed to be forwarded correctly,
239 so this can also be considered a bug fix although chunk-encoded request
240 bodies aren't commonly used in the real world.
241 - Add support for Tor's optimistic-data SOCKS extension, which can reduce the
242 latency for requests on newly created connections. Currently only the
243 headers are sent optimistically and only if the client request has already
244 been read completely which rules out requests with large bodies.
245 - After preventing the client from pipelining, don't signal keep-alive
246 intentions. When looking at the response headers alone, it previously
247 wasn't obvious from the client's perspective that no additional responses
249 - Stop considering client sockets tainted after receiving a request with body.
250 It hasn't been necessary for a while now and unnecessarily causes test
251 failures when using curl's test suite.
252 - Allow HTTP/1.0 clients to signal interest in keep-alive through the
253 Proxy-Connection header. While such client are rare in the real world, it
254 doesn't hurt and couple of curl tests rely on it.
255 - Only remove duplicated Content-Type headers when filters are enabled.
256 If they are not it doesn't cause ill effects and the user might not want it.
257 Downgrade the removal message to LOG_LEVEL_HEADER to clarify that it's not
258 an error in Privoxy and is unlikely to cause any problems in general.
259 Anonymously reported in #3599335.
260 - Set the socket option SO_LINGER for the client socket.
261 - Move several variable declarations to the beginning of their code block.
262 It's required when compiling with gcc 2.95 which is still used on some
263 platforms. Initial patch submitted by Simon South in #3564815.
264 - Optionally try to sanity-check strptime() results before trusting them.
265 Broken strptime() implementations have caused problems in the past and
266 the most recent offender seems to be FreeBSD's libc (standards/173421).
267 - When filtering is enabled, let Range headers pass if the range starts at
268 the beginning. This should work around (or at least reduce) the video
269 playback issues with various Apple clients as reported by Duc in #3426305.
270 - Do not confuse a client hanging up with a connection time out. If a client
271 closes its side of the connection without sending a request line, do not
272 send the CLIENT_CONNECTION_TIMEOUT_RESPONSE, but report the condition
274 - Allow closing curly braces as part of action values as long as they are
276 - On Windows, the logfile is now written before showing the GUI error
277 message which blocks until the user acknowledges it.
278 Reported by Adriaan in #3593603.
279 - Remove an unreasonable parameter limit in the CGI interface. The new
280 parameter limit depends on the memory available and is currently unlikely
281 to be reachable, due to other limits in both Privoxy and common clients.
282 Reported by Andrew on ijbswa-users@.
283 - Decrease the chances of parse failures after requests with unsupported
284 methods were sent to the CGI interface.
286 - Action file improvements:
287 - Remove the comment that indicated that updated default.action versions
288 are released on their own.
289 - Block 'optimize.indieclick.com/' and 'optimized-by.rubiconproject.com/'
290 - Unblock 'adjamblog.wordpress.com/' and 'adjamblog.files.wordpress.com/'.
291 Reported by Ryan Farmer in #3496116.

303 - Block 'imp.double.net/'. Reported by David Bo in #3070411.
304 - Block 'gm-link.com/' which is used for email tracking.
305 Reported by David Bo in #1812733.
306 - Verify that requests to "bwp." are blocked. URL taken from #1736879
307 submitted by Francois Marier.
308 - Block '/.*bannerid='. Reported by Adam Piggott in #2975779.
309 - Block 'cltomedia.info/delivery/' and '.adexprt.com/'.
310 Anonymously reported in #2965254.

315 - Update path pattern for Coremetrics and add tests.
316 Pattern and URLs submitted by Adam Piggott #3168443.
317 - Enable +fast-redirects{check-decoded-url} for 'tr.anp.se/'.
318 Reported by David Bo in #3268832.
319 - Unblock '.conrad.se/newsletter/banners/'. Reported by David Bo in #3413824.
320 - Block '.tynt.com/'. Reported by Dan Stahlke in #3421767.
321 - Unblock '.bbci.co.uk/radio/'. Reported by Adam Piggott in #3569603.
322 - Block requests to 'service.maxymiser.net/'.
323 Reported by johnd16 in #3118401 (with a previous URL).
324 - Disable fast-redirects for Google's "let's pretend your computer is
326 - Unblock '/.*download' to resolve actionsfile feedback #3498129.
327 Submitted by Steven Kolins (soundcloud.com not working).
328 - Unblock '.wlxrs.com/' which is required by hotmail.com.
329 Fixes #3413827 submitted by David Bo.
330 - Add two unblock patterns for popup radio and TV players.
331 Submitted by Adam Piggott in #3596089.
333 - Filter file improvements & bug fixes:
334 - Add a referer tagger.
335 - Reduce the likelihood that the google filter messes up HTML-generating
336 JavaScript. Reported by Zeno Kugy in #3520260.
338 - Documentation improvements:
339 - Revised all OS X sections due to new packaging module (OSXPackageBuilder).
340 - Update the list of supported operating systems to clarify that all Windows
341 versions after 95 are expected to work and note that the platform-specific
342 code for AmigaOS and QNX currently isn't maintained.
343 - Update 'Signals' section, the only explicitly handled signals are SIGINT,
345 - Add Haiku to the list of operating systems on which Privoxy is known to
347 - Add DragonFly to the list of BSDs on which Privoxy is known to run.
348 - Removed references to redhat-specific documentation set since it no longer
350 - Removed references to building PDFs since we no longer do so.
351 - Multiple listen-address directives are supported since 3.0.18, correct the
352 documentation to say so.
353 - Remove bogus section about long and short being preferable to int.
354 - Corrected some Internet JunkBuster references to Privoxy.
355 - Removed references to www.junkbusters.com since it is no longer
356 maintained. Reported by Angelina Matson.
357 - Various grammar and spelling corrections
358 - Add a client-header-tagger{} example for disabling filtering for range
360 - Correct a URL in the "Privoxy with Tor" FAQ.
361 - Spell 'refresh-tags' correctly. Reported by Don in #3571927.
362 - Sort manpage options alphabetically.
363 - Remove an incorrect sentence in the toggle section. The toggle state
364 doesn't affect whether or not the Windows version uses the tray icon.
365 Reported by Zeno Kugy in #3596395.
366 - Add new contributors since 3.0.19.
368 - Log message improvements:
369 - When stopping to watch a client socket due to pipelining, additionally log
371 - Log the client socket and its condition before closing it. This makes it
372 more obvious that the socket actually gets closed and should help when
373 diagnosing problems like #3464439.
374 - In case of SOCKS5 failures, do not explicitly log the server's response.
375 It hasn't helped so far and the response can already be logged by enabling
376 "debug 32768" anyway. This reverts v1.81 and the follow-up bug fix v1.84.
377 - Relocate the connection-accepted message from listen_loop() to serve().
378 This way it's printed by the thread that is actually serving the
379 connection which is nice when grepping for thread ids in log files.
382 - Remove compatibility layer for versions prior to 3.0 since it has been
383 obsolete for more than 10 years now.
384 - Remove the ijb_isupper() and ijb_tolower() macros from parsers.c since
385 they aren't used in this file.
386 - Removed the 'Functions declared include:' comment sections since they tend
387 to be incomplete, incorrect and out of date and the benefit seems
389 - Various comment grammar and comprehensibility improvements.
390 - Remove a pointless fflush() call in chat(). Flushing all streams pretty
391 much all the time for no obvious reason is ridiculous.
392 - Relocate ijb_isupper()'s definition to project.h and get the ijb_tolower()
393 definition from there, too.
394 - Relocate ijb_isdigit()'s definition to project.h.
395 - Rename ijb_foo macros to privoxy_foo.
396 - Add malloc_or_die() which will allow to simplify code paths where malloc()
397 failures don't need to be handled gracefully.
398 - Add strdup_or_die() which will allow to simplify code paths where strdup()
399 failures don't need to be handled gracefully.
400 - Replace strdup() calls with strdup_or_die() calls where it's safe and
402 - Fix white-space around parentheses.
403 - Add missing white-space behind if's and the following parentheses.
404 - Unwrap a memcpy() call in resolve_hostname_to_ip().
405 - Declare pcrs_get_delimiter()'s delimiters[] static const.
406 - Various optimisations to remove dead code and merge inefficient code
407 structures for improved clarity, performance or code compactness.
408 - Various data type corrections.
409 - Change visibility of several code segments when compiling without
410 FEATURE_CONNECTION_KEEP_ALIVE enabled for clarity.
411 - In pcrs_get_delimiter(), do not use delimiters outside the ASCII range.
412 Fixes a clang complaint.
413 - Fix an error message in get_last_url() nobody is supposed to see.
414 Reported by Matthew Fischer in #3507301.
415 - Fix a typo in the no-zlib-support complaint. Patch submitted by Matthew
417 - Shorten ssplit()'s prototype by removing the last two arguments. We always
418 want to skip empty fields and ignore leading delimiters, so having
419 parameters for this only complicates the API.
420 - Use an enum for the type of the action value.
421 - Rename action_name's member takes_value to value_type as it isn't used as
423 - Turn family mismatches in match_sockaddr() into fatal errors.
424 - Let enlist_unique_header() verify that the caller didn't pass a header
425 containing either \r or \n.
426 - Change the hashes used in load_config() to unsigned int. That's what
427 hash_string() actually returns and using a potentially larger type
429 - Use privoxy_tolower() instead of vanilla tolower() with manual casting of
431 - Catch ssplit() failures in parse_cgi_parameters().
433 - Privoxy-Regression-Test:
434 - Add an 'Overwrite condition' directive to skip any matching tests before
435 it. As it has a global scope, using it is more convenient than clowning
436 around with the Ignore directive.
437 - Log to STDOUT instead of STDERR.
438 - Include the Privoxy version in the output.
439 - Various grammar and spelling corrections in documentation and code.
440 - Additional tests for range requests with filtering enabled.
441 - Tests with mostly invalid range request.
442 - Add a couple of hide-if-modified-since{} tests with different date formats.
443 - Cleaned up the format of the regression-tests.action file to match the
444 format of default.action.
445 - Remove the "Copyright" line from print_version(). When using --help, every
446 line of screen space matters and thus shouldn't be wasted on things the
447 user doesn't care about.
449 - Privoxy-Log-Parser:
450 - Improve the --statistics performance by skipping sanity checks for input
451 that shouldn't affect the results anyway. Add a --strict-checks option
452 that enables some of the checks again, just in case anybody cares.
453 - The distribution of client requests per connection is included in
454 the --statistic output.
455 - The --accept-unknown-messages option has been removed and the behavior
457 - Accept and (mostly) highlight new log messages introduced with
461 - Bump generated Firefox version to 17.
463 - GNUmakefile improvements:
464 - The dok-tidy target no longer taints documents with a tidy-mark
465 - Change RA_MODE from 0664 to 0644. Suggested by Markus Dittrich in
467 - Remove tidy's clean flag as it changes the scope of attributes.
468 Link-specific colors end up being applied to all text. Reported by Adam
470 - Leave it up to the user whether or not smart tags are inserted.
471 - Let w3m itself do the line wrapping for the config file. It works better
472 than fmt as it can honour pre tags causing less unintentional line breaks.
473 - Ditch a pointless '-r' passed to rm to delete files.
474 - The config-file target now requires less manual intervention and updates
476 - Change WDUMP to generate ASCII. Add WDUMP_UTF8 to allow UTF-8 in the
477 AUTHORS file so the names are right.
478 - Stop pretending that lynx and links are supported for the documentation.
480 - configure improvements:
481 - On Haiku, do not pass -lpthread to the compiler. Haiku's pthreads
482 implementation is contained in its system library, libroot, so no
483 additional library needs to be searched.
484 Patch submitted by Simon South in #3564815.
485 - Additional Haiku-specific improvements. Disable checks intended for
486 multi-user systems as Haiku is presently single-user. Group Haiku-specific
487 settings in their own section, following the pattern for Solaris, OS/2 and
488 AmigaOS. Add additional library-related settings to remove the need for
489 providing configure with custom LDFLAGS.
490 Submitted by Simon South in #3574538.
492 *** Version 3.0.19 Stable ***
495 - Prevent a segmentation fault when de-chunking buffered content.
496 It could be triggered by malicious web servers if Privoxy was
497 configured to filter the content and running on a platform
498 where SIZE_T_MAX isn't larger than UINT_MAX, which probably
499 includes most 32-bit systems. On those platforms, all Privoxy
500 versions before 3.0.19 appear to be affected.
501 To be on the safe side, this bug should be presumed to allow
502 code execution as proving that it doesn't seems unrealistic.
503 - Do not expect a response from the SOCKS4/4A server until it
504 got something to respond to. This regression was introduced
505 in 3.0.18 and prevented the SOCKS4/4A negotiation from working.
506 Reported by qqqqqw in #3459781.
508 - General improvements:
509 - Fix an off-by-one in an error message about connect failures.
510 - Use a GNUMakefile variable for the webserver root directory and
511 update the path. Sourceforge changed it which broke various
513 - Update the CODE_STATUS description.
515 *** Version 3.0.18 Stable ***
518 - If a generated redirect URL contains characters RFC 3986 doesn't
519 permit, they are (re)encoded. Not doing this makes Privoxy versions
520 from 3.0.5 to 3.0.17 susceptible to HTTP response splitting (CWE-113)
521 attacks if the +fast-redirects{check-decoded-url} action is used.
522 - Fix a logic bug that could cause Privoxy to reuse a server
523 socket after it got tainted by a server-header-tagger-induced
524 block that was triggered before the whole server response had
525 been read. If keep-alive was enabled and the request following
526 the blocked one was to the same host and using the same forwarding
527 settings, Privoxy would send it on the tainted server socket.
528 While the server would simply treat it as a pipelined request,
529 Privoxy would later on fail to properly parse the server's
530 response as it would try to parse the unread data from the
531 first response as server headers for the second one.
532 Regression introduced in 3.0.17.
533 - When implying keep-alive in client_connection(), remember that
534 the client didn't. Fixes a regression introduced in 3.0.13 that
535 would cause Privoxy to wait for additional client requests after
536 receiving a HTTP/1.1 request with "Connection: close" set
537 and connection sharing enabled.
538 With clients which terminates the client connection after detecting
539 that the whole body has been received it doesn't really matter,
540 but with clients that don't the connection would be kept open until
542 - Fix a subtle race condition between prepare_csp_for_next_request()
543 and sweep(). A thread preparing itself for the next client request
544 could briefly appear to be inactive.
545 If all other threads were already using more recent files,
546 the thread could get its files swept away under its feet.
547 So far this has only been reproduced while stress testing in
548 valgrind while touching action files in a loop. It's unlikely
549 to have caused any actual problems in the real world.
550 - Disable filters if SDCH compression is used unless filtering is forced.
551 If SDCH was combined with a supported compression algorithm, Privoxy
552 previously could try to decompress it and ditch the Content-Encoding
553 header even though the SDCH compression wasn't dealt with.
554 Reported by zebul666 in #3225863.
555 - Make a copy of the --user value and only mess with that when splitting
556 user and group. On some operating systems modifying the value directly
557 is reflected in the output of ps and friends and can be misleading.
558 Reported by zepard in #3292710.
559 - If forwarded-connect-retries is set, only retry if Privoxy is actually
560 forwarding the request. Previously direct connections would be retried
562 - Fixed a small memory leak when retrying connections with IPv6
564 - Remove an incorrect assertion in compile_dynamic_pcrs_job_list()
565 It could be triggered by a pcrs job with an invalid pcre
566 pattern (for example one that contains a lone quantifier).
567 - If the --user argument user[.group] contains a dot, always bail out
568 if no group has been specified. Previously the intended, but undocumented
569 (and apparently untested), behaviour was to try interpreting the whole
570 argument as user name, but the detection was flawed and checked for '0'
571 instead of '\0', thus merely preventing group names beginning with a zero.
572 - In html_code_map[], use a numeric character reference instead of '
573 which wasn't standardized before XHTML 1.0.
574 - Fix an invalid free when compiled with FEATURE_GRACEFUL_TERMINATION
575 and shut down through http://config.privoxy.org/die
576 - In get_actions(), fix the "temporary" backwards compatibility hack
577 to accept block actions without reason.
578 It also covered other actions that should be rejected as invalid.
579 Reported by Billy Crook.
581 - General improvements:
582 - Privoxy can (re)compress buffered content before delivering
583 it to the client. Disabled by default as most users wouldn't
585 - The +fast-redirects{check-decoded-url} action checks URL
586 segments separately. If there are other parameters behind
587 the redirect URL, this makes it unnecessary to cut them off
588 by additionally using a +redirect{} pcrs command.
589 Initial patch submitted by Jamie Zawinski in #3429848.
590 - When loading action sections, verify that the referenced filters
591 exist. Currently missing filters only result in an error message,
592 but eventually the severity will be upgraded to fatal.
593 - Allow to bind to multiple separate addresses.
594 Patch set submitted by Petr Pisar in #3354485.
595 - Set socket_error to errno if connecting fails in rfc2553_connect_to().
596 Previously rejected direct connections could be incorrectly reported
597 as DNS issues if Privoxy was compiled with IPv6 support.
598 - Adjust url_code_map[] so spaces are replaced with %20 instead of '+'
599 While '+' can be used by client's submitting form data, this is not
600 actually what Privoxy is using the lookups for. This is more of a
601 cosmetic issue and doesn't fix any known problems.
602 - When compiled without FEATURE_FAST_REDIRECTS, do not silently
603 ignore +fast-redirect{} directives
604 - Added a workaround for GNU libc's strptime() reporting negative
605 year values when the parsed year is only specified with two digits.
606 On affected systems cookies with such a date would not be turned
607 into session cookies by the +session-cookies-only action.
608 Reported by Vaeinoe in #3403560
609 - Fixed bind failures with certain GNU libc versions if no non-loopback
610 IP address has been configured on the system. This is mainly an issue
611 if the system is using DHCP and Privoxy is started before the network
612 is completely configured.
613 Reported by Raphael Marichez in #3349356.
614 Additional insight from Petr Pisar.
615 - Privoxy log messages now use the ISO 8601 date format %Y-%m-%d.
616 It's only slightly longer than the old format, but contains
617 the full date including the year and allows sorting by date
618 (when grepping in multiple log files) without hassle.
619 - In get_last_url(), do not bother trying to decode URLs that do
620 not contain at least one '%' sign. It reduces the log noise and
621 a number of unnecessary memory allocations.
622 - In case of SOCKS5 failures, dump the socks response in the log message.
623 - Simplify the signal setup in main().
624 - Streamline socks5_connect() slightly.
625 - In socks5_connect(), require a complete socks response from the server.
626 Previously Privoxy didn't care how much data the server response
627 contained as long as the first two bytes contained the expected
628 values. While at it, shrink the buffer size so Privoxy can't read
629 more than a whole socks response.
630 - In chat(), do not bother to generate a client request in case of
631 direct CONNECT requests. It will not be used anyway.
632 - Reduce server_last_modified()'s stack size.
633 - Shorten get_http_time() by using strftime().
634 - Constify the known_http_methods pointers in unknown_method().
635 - Constify the time_formats pointers in parse_header_time().
636 - Constify the formerly_valid_actions pointers in action_used_to_be_valid().
637 - Introduce a GNUMakefile MAN_PAGE variable that defaults to privoxy.1.
638 The Debian package uses section 8 for the man page and this
639 should simplify the patch.
640 - Deduplicate the INADDR_NONE definition for Solaris by moving it to jbsockets.h
641 - In block_url(), ditch the obsolete workaround for ancient Netscape versions
642 that supposedly couldn't properly deal with status code 403.
643 - Remove a useless NULL pointer check in load_trustfile().
644 - Remove two useless NULL pointer checks in load_one_re_filterfile().
645 - Change url_code_map[] from an array of pointers to an array of arrays
646 It removes an unnecessary layer of indirection and on 64bit system reduces
647 the size of the binary a bit.
648 - Fix various typos. Fixes taken from Debian's 29_typos.dpatch by Roland Rosenfeld.
649 - Add a dok-tidy GNUMakefile target to clean up the messy HTML
650 generated by the other dok targets.
651 - GNUisms in the GNUMakefile have been removed.
652 - Change the HTTP version in static responses to 1.1
653 - Synced config.sub and config.guess with upstream
654 2011-11-11/386c7218162c145f5f9e1ff7f558a3fbb66c37c5.
655 - Add a dedicated function to parse the values of toggles. Reduces duplicated
656 code in load_config() and provides better error handling. Invalid or missing
657 toggle values are now a fatal error instead of being silently ignored.
658 - Terminate HTML lines in static error messages with \n instead of \r\n.
659 - Simplify cgi_error_unknown() a bit.
660 - In LogPutString(), don't bother looking at pszText when not
661 actually logging anything.
662 - Change ssplit()'s fourth parameter from int to size_t.
663 Fixes a clang complaint.
664 - Add a warning that the statistics currently can't be trusted.
665 Mention Privoxy-Log-Parser's --statistics option as
666 an alternative for the time being.
667 - In rfc2553_connect_to(), start setting cgi->error_message on error.
668 - Change the expected status code returned for http://p.p/die depending
669 on whether or not FEATURE_GRACEFUL_TERMINATION is available.
670 - In cgi_die(), mark the client connection for closing.
671 If the client will fetch the style sheet through another connection
672 it gets the main thread out of the accept() state and should thus
673 trigger the actual shutdown.
674 - Add a proper CGI message for cgi_die().
675 - Don't enforce a logical line length limit in read_config_line().
676 - Slightly refactor server_last_modified() to remove useless gmtime*() calls.
677 - In get_content_type(), also recognize '.jpeg' as JPEG extension.
678 - Add '.png' to the list of recognized file extensions in get_content_type().
679 - In block_url(), consistently use the block reason "Request blocked by Privoxy"
680 In two places the reason was "Request for blocked URL" which hides the
681 fact that the request got blocked by Privoxy and isn't necessarily
682 correct as the block may be due to tags.
683 - In listen_loop(), reload the configuration files after accepting
684 a new connection instead of before.
685 Previously the first connection that arrived after a configuration
686 change would still be handled with the old configuration.
687 - In chat()'s receive-data loop, skip a client socket check if
688 the socket will be written to right away anyway. This can
689 increase the transfer speed for unfiltered content on fast
691 - The socket timeout is used for SOCKS negotiations as well which
692 previously couldn't timeout.
693 - Don't keep the client connection alive if any configuration file
694 changed since the time the connection came in. This is closer to
695 Privoxy's behaviour before keep-alive support for client connection
696 has been added and also less confusing in general.
697 - Treat all Content-Type header values containing the pattern
698 'script' as a sign of text. Reported by pribog in #3134970.
700 - Action file improvements:
701 - Moved the site-specific block pattern section below the one for the
702 generic patterns so for requests that are matched in both, the block
703 reason for the domain is shown which is usually more useful than showing
704 the one for the generic pattern.
705 - Remove -prevent-compression from the fragile alias. It's no longer
706 used anywhere by default and isn't known to break stuff anyway.
707 - Add a (disabled) section to block various Facebook tracking URLs.
708 Reported by Dan Stahlke in #3421764.
709 - Add a (disabled) section to rewrite and redirect click-tracking
710 URLs used on news.google.com.
711 Reported by Dan Stahlke in #3421755.
712 - Unblock linuxcounter.net/.
713 Reported by Dan Stahlke in #3422612.
714 - Block 'www91.intel.com/' which is used by Omniture.
715 Reported by Adam Piggott in #3167370.
716 - Disable the handle-as-empty-doc-returns-ok option and mark it as deprecated.
717 Reminded by tceverling in #2790091.
718 - Add ".ivwbox.de/" to the "Cross-site user tracking" section.
719 Reported by Nettozahler in #3172525.
720 - Unblock and fast-redirect ".awin1.com/.*=http://".
721 Reported by Adam Piggott in #3170921.
722 - Block "b.collective-media.net/".
723 - Widen the Debian popcon exception to "qa.debian.org/popcon".
724 Seen in Debian's 05_default_action.dpatch by Roland Rosenfeld.
725 - Block ".gemius.pl/" which only seems to be used for user tracking.
726 Reported by johnd16 in #3002731. Additional input from Lee and movax.
727 - Disable banners-by-size filters for '.thinkgeek.com/'.
728 The filter only seems to catch pictures of the inventory.
729 - Block requests for 'go.idmnet.bbelements.com/please/showit/'.
730 Reported by kacperdominik in #3372959.
731 - Unblock adainitiative.org/.
732 - Add a fast-redirects exception for '.googleusercontent.com/.*=cache'.
733 - Add a fast-redirects exception for webcache.googleusercontent.com/.
734 - Unblock http://adassier.wordpress.com/ and http://adassier.files.wordpress.com/.
736 - Filter file improvements:
737 - Let the yahoo filter hide '.ads'.
738 - Let the msn filter hide overlay ads for Facebook 'likes' in search
739 results and elements with the id 's_notf_div'. They only seem to be
740 used to advertise site 'enhancements'.
741 - Let the js-events filter additionally disarm setInterval().
742 Suggested by dg1727 in #3423775.
744 - Documentation improvements:
745 - Clarify the effect of compiling Privoxy with zlib support.
746 Suggested by dg1727 in #3423782.
747 - Point out that the SourceForge messaging system works like a black
748 hole and should thus not be used to contact individual developers.
749 - Mention some of the problems one can experience when not explicitly
750 configuring an IP addresses as listen address.
751 - Explicitly mention that hostnames can be used instead of IP addresses
752 for the listen-address, that only the first address returned will be
753 used and what happens if the address is invalid.
754 Requested by Calestyo in #3302213.
756 - Log message improvements:
757 - If only the server connection is kept alive, do not pretend to
758 wait for a new client request.
759 - Remove a superfluous log message in forget_connection().
760 - In chat(), properly report missing server responses as such
761 instead of calling them empty.
762 - In forwarded_connect(), fix a log message nobody should ever see.
763 - Fix a log message in socks5_connect(), a failed write operation
764 was logged as failed read operation.
765 - Let load_one_actions_file() properly complain about a missing
766 '{' at the beginning of the file.
767 Simply stating that a line is invalid isn't particularly helpful.
768 - Do not claim to listen on a socket until Privoxy actually does.
769 Patch submitted by Petr Pisar #3354485
770 - Prevent a duplicated LOG_LEVEL_CLF message when sending out
771 the "no-server-data" response.
772 - Also log the client socket when dropping a connection.
773 - Include the destination host in the 'Request ... marked for
774 blocking. limit-connect{...} doesn't allow CONNECT ...' message
775 Patch submitted by Saperski in #3296250.
776 - Prevent a duplicated log message if none of the resolved IP
777 addresses were reachable.
778 - In connect_to(), do not pretend to retry if forwarded-connect-retries
780 - When a specified user or group can't be found, put the name in
781 single-quotes when logging it.
782 - In rfc2553_connect_to(), explain getnameinfo() errors better.
783 - Remove a useless log message in chat().
784 - When retrying to connect, also log the maximum number of connection
786 - Rephrase a log message in compile_dynamic_pcrs_job_list().
787 Divide the error code and its meaning with a colon. Call the pcrs
788 job dynamic and not the filter. Filters may contain dynamic and
789 non-dynamic pcrs jobs at the same time. Only mention the name of
790 the filter or tagger, but don't claim it's a filter when it could
792 - In a fatal error message in load_one_actions_file(), cover both
793 URL and TAG patterns.
794 - In pcrs_strerror(), properly report unknown positive error code
795 values as such. Previously they were handled like 0 (no error).
796 - In compile_dynamic_pcrs_job_list(), also log the actual error code as
797 pcrs_strerror() doesn't handle all errors reported by pcre.
798 - Don't bother trying to continue chatting if the client didn't ask for it.
799 Reduces log noise a bit.
800 - Make two fatal error message in load_one_actions_file() more descriptive.
801 - In cgi_send_user_manual(), log when rejecting a file name due to '/' or '..'.
802 - In load_file(), log a message if opening a file failed.
803 The CGI error message alone isn't too helpful.
804 - In connection_destination_matches(), improve two log messages
805 to help understand why the destinations don't match.
806 - Rephrase a log message in serve(). Client request arrival
807 should be differentiated from closed client connections now.
808 - In serve(), log if a client connection isn't reused due to a
809 configuration file change.
810 - Let mark_server_socket_tainted() always mark the server socket tainted,
811 just don't talk about it in cases where it has no effect. It doesn't change
812 Privoxy's behaviour, but makes understanding the log file easier.
815 - Added a --disable-ipv6-support switch for platforms where support
816 is detected but doesn't actually work.
817 - Do not check for the existence of strerror() and memmove() twice
818 - Remove a useless test for setpgrp(2). Privoxy doesn't need it and
819 it can cause problems when cross-compiling.
820 - Rename the --disable-acl-files switch to --disable-acl-support.
821 Since about 2001, ACL directives are specified in the standard
823 - Update the URL of the 'Removing outdated PCRE version after the
824 next stable release' posting. The old URL stopped working after
825 one of SF's recent site "optimizations". Reported by Han Liu.
827 - Privoxy-Regression-Test:
828 - Added --shuffle-tests option to increase the chances of detection race conditions.
829 - Added a --local-test-file option that allows to use Privoxy-Regression-Test without Privoxy.
830 - Added tests for missing socks4 and socks4a forwarders.
831 - The --privoxy-address option now works with IPv6 addresses containing brackets, too.
832 - Perform limited sanity checks for parameters that are supposed to have numerical values.
833 - Added a --sleep-time option to specify a number of seconds to
834 sleep between tests, defaults to 0.
835 - Disable the range-requests tagger for tests that break if it's enabled.
836 - Log messages use the ISO 8601 date format %Y-%m-%d.
837 - Fix spelling in two error messages.
838 - In the --help output, include a list of supported tests and their default levels.
839 - Adjust the tests to properly deal with FEATURE_TOGGLE being disabled.
841 - Privoxy-Log-Parser:
842 - Perform limited sanity checks for command line parameters that
843 are supposed to have numerical values.
844 - Implement a --unbreak-lines-only option to try to revert MUA breakage.
845 - Accept and highlight: Added header: Content-Encoding: deflate
846 - Accept and highlight: Compressed content from 29258 to 8630 bytes.
847 - Accept and highlight: Client request arrived in time on socket 21.
848 - Highlight: Didn't receive data in time: a.fsdn.com:443
849 - Accept log messages with ISO 8601 time stamps, too.
852 - Bump generated Firefox version to 8.0.
853 - Only randomize the release date if the new --randomize-release-date
854 option is enabled. Firefox versions after 4 use a fixed date string
857 *** Version 3.0.17 Stable ***
859 - Fixed last-chunk-detection for responses where the body was small
860 enough to be read with the headers, causing Privoxy to wait for the
861 end of the content until the server closed the connection or the
862 request timed out. Reported by "Karsten" in #3028326.
863 - Responses with status code 204 weren't properly detected as body-less
864 like RFC2616 mandates. Like the previous bug, this caused Privoxy to
865 wait for the end of the content until the server closed the connection
866 or the request timed out. Fixes #3022042 and #3025553, reported by a
867 user with no visible name. Most likely also fixes a bunch of other
868 AJAX-related problem reports that got closed in the past due to
869 insufficient information and lack of feedback.
870 - Fixed an ACL bug that made it impossible to build a blacklist.
871 Usually the ACL directives are used in a whitelist, which worked
872 as expected, but blacklisting is still useful for public proxies
873 where one only needs to deny known abusers access.
874 - Added LOG_LEVEL_RECEIVED to log the not-yet-parsed data read from the
875 network. This should make debugging various parsing issues a lot easier.
876 - The IPv6 code is enabled by default on Windows versions that support it.
877 Patch submitted by oCameLo in #2942729.
878 - In mingw32 versions, the user.filter file is reachable through the
879 GUI, just like default.filter is. Feature request 3040263.
880 - Added the configure option --enable-large-file-support to set a few
881 defines that are required by platforms like GNU/Linux to support files
882 larger then 2GB. Mainly interesting for users without proper logfile
884 - Logging with "debug 16" no longer stops at the first nul byte which is
885 pretty useless. Non-printable characters are replaced with their hex value
886 so the result can't span multiple lines making parsing them harder then
888 - Privoxy logs when reading an action, filter or trust file.
889 - Fixed incorrect regression test markup which caused a test in
890 3.0.16 to fail while Privoxy itself was working correctly.
891 While Privoxy accepts hide-referer, too, the action name is actually
892 hide-referrer which is also the name used one the final results page,
893 where the test expected the alias.
895 - CGI interface improvements:
896 - In finish_http_response(), continue to add the 'Connection: close'
897 header if the client connection will not be kept alive.
898 Anonymously pointed out in #2987454.
899 - Apostrophes in block messages no longer cause parse errors
900 when the blocked page is viewed with JavaScript enabled.
901 Reported by dg1727 in #3062296.
902 - Fix a bunch of anchors that used underscores instead of dashes.
903 - Allow to keep the client connection alive after crunching the previous request.
904 Already opened server connections can be kept alive, too.
905 - In cgi_show_url_info(), don't forget to prefix URLs that only contain
906 http:// or https:// in the path. Fixes #2975765 reported by Adam Piggott.
907 - Show the 404 CGI page if cgi_send_user_manual() is called while
908 local user manual delivery is disabled.
910 - Action file improvements:
911 - Enable user.filter by default. Suggested by David White in #3001830.
912 - Block .sitestat.com/. Reported by johnd16 in #3002725.
913 - Block .atemda.com/. Reported by johnd16 in #3002723.
914 - Block js.adlink.net/. Reported by johnd16 in #3002720.
915 - Block .analytics.yahoo.com/. Reported by johnd16 in #3002713.
916 - Block sb.scorecardresearch.com, too. Reported by dg1727 in #2992652.
917 - Fix problems noticed on Yahoo mail and news pages.
918 - Remove the too broad yahoo section, only keeping the
919 fast-redirects exception as discussed on ijbswa-devel@.
920 - Don't block adesklets.sourceforge.net. Reported in #2974204.
921 - Block chartbeat ping tracking. Reported in #2975895.
922 - Tag CSS and image requests with cautious and medium settings, too.
923 - Don't handle view.atdmt.com as image. It's used for click-throughs
924 so users should be able to "go there anyway".
925 Reported by Adam Piggott in #2975927.
926 - Also let the refresh-tags filter remove invalid refresh tags where
927 the 'url=' part is missing. Anonymously reported in #2986382.
928 While at it, update the description to mention the fact that only
929 refresh tags with refresh times above 9 seconds are covered.
930 - javascript needs to be blocked with +handle-as-empty-document to
931 work around Firefox bug 492459. So move .js blockers from
932 +block{Might be a web-bug.} -handle-as-empty-document to
933 +block{Might be a web-bug.} +handle-as-empty-document.
934 - ijbswa-Feature Requests-3006719 - Block 160x578 Banners.
935 - Block another omniture tracking domain.
936 - Added a range-requests tagger.
937 - Added two sections to get Flickr's Ajax interface working with
938 default pre-settings. If you change the configuration to block
939 cookies by default, you'll need additional exceptions.
940 Reported by Mathias Homann in #3101419 and by Patrick on ijbswa-users@.
942 - Documentation improvements:
943 - Explicitly mention how to match all URLs.
944 - Consistently recommend socks5 in the Tor FAQ entry and mention
945 its advantage compared to socks4a. Reported by David in #2960129.
946 - Slightly improve the explanation of why filtering may appear
948 - Grammar fixes for the ACL section.
949 - Fixed a link to the 'intercepting' entry and add another one.
950 - Rename the 'Other' section to 'Mailing Lists' and reword it
951 to make it clear that nobody is forced to use the trackers
952 - Note that 'anonymously' posting on the trackers may not always
954 - Suggest to enable debug 32768 when suspecting parsing problems.
956 - Privoxy-Log-Parser improvements:
957 - Gather statistics for ressources, methods, and HTTP versions
959 - Also gather statistics for blocked and redirected requests.
960 - Provide the percentage of keep-alive offers the client accepted.
961 - Add a --url-statistics-threshold option.
962 - Add a --host-statistics-threshold option to also gather
963 statistics about how many request where made per host.
964 - Fix a bug in handle_loglevel_header() where a 'scan: ' got lost.
965 - Add a --shorten-thread-ids option to replace the thread id with
967 - Accept and ignore: Looks like we got the last chunk together
968 with the server headers. We better stop reading.
969 - Accept and ignore: Continue hack in da house.
970 - Accept and higlight: Rejecting connection from 10.0.0.2.
971 Maximum number of connections reached.
972 - Accept and highlight: Loading actions file: /usr/local/etc/privoxy/default.action
973 - Accept and highlight: Loading filter file: /usr/local/etc/privoxy/default.filter
974 - Accept and highlight: Killed all-caps Host header line: HOST: bestproxydb.com
975 - Accept and highlight: Reducing expected bytes to 0. Marking
976 the server socket tainted after throwing 4 bytes away.
977 - Accept: Merged multiple header lines to: 'X-FORWARDED-PROTO: http X-HOST: 127.0.0.1'
980 - Remove the next member from the client_state struct. Only the main
981 thread needs access to all client states so give it its own struct.
982 - Garbage-collect request_contains_null_bytes().
983 - Ditch redundant code in unload_configfile().
984 - Ditch LogGetURLUnderCursor() which doesn't seem to be used anywhere.
985 - In write_socket(), remove the write-only variable write_len in
986 an ifdef __OS2__ block. Spotted by cppcheck.
987 - In connect_to(), don't declare the variable 'flags' on OS/2 where
988 it isn't used. Spotted by cppcheck.
989 - Limit the scope of various variables. Spotted by cppcheck.
990 - In add_to_iob(), turn an interestingly looking for loop into a
992 - Code cleanup in preparation for external filters.
993 - In listen_loop(), mention the socket on which we accepted the
994 connection, not just the source IP address.
995 - In write_socket(), also log the socket we're writing to.
996 - In log_error(), assert that escaped characters get logged
997 completely or not at all.
998 - In log_error(), assert that ival and sval have reasonable values.
999 There's no reason not to abort() if they don't.
1000 - Remove an incorrect cgi_error_unknown() call in a
1001 cannot-happen-situation in send_crunch_response().
1002 - Clean up white-space in http_response definition and
1003 move the crunch_reason to the beginning.
1004 - Turn http_response.reason into an enum and rename it
1005 to http_response.crunch_reason.
1006 - Silence a 'gcc (Debian 4.3.2-1.1) 4.3.2' warning on i686 GNU/Linux.
1007 - Fix white-space in a log message in remove_chunked_transfer_coding().
1008 While at it, add a note that the message doesn't seem to
1009 be entirely correct and should be improved later on.
1011 - GNUmakefile improvements:
1012 - Use $(SSH) instead of ssh, so one only needs to specify a username once.
1013 - Removed references to the action feedback thingy that hasn't been
1015 - Consistently use shell.sourceforge.net instead of shell.sf.net so
1016 one doesn't need to check server fingerprints twice.
1017 - Removed GNUisms in the webserver and webactions targets so they
1018 work with standard tar.
1020 *** Version 3.0.16 Stable ***
1022 - Added the config file option handle-as-empty-doc-returns-ok to
1023 work around Firefox bug #492459, which causes Firefox to hang
1024 if JavaScripts are blocked in certain situations. The option is
1025 enabled in the default config file.
1026 - Added the config file option default-server-timeout to control the
1027 assumed default server timeout. Since Privoxy no longer returns
1028 an error message for connection resets on reused client connections,
1029 assuming larger server timeout values appears to actually work
1030 pretty well as long as connections aren't shared.
1031 - Added optional support for FreeBSD's accf_http(9). Use the
1032 configure option --enable-accept-filter to enable it.
1033 - Added fancier Privoxy icons for win32. Contributed by Jeff H.
1034 - In daemon mode, fd 0, 1 and 2 are bound to /dev/null.
1035 - Resolve localhost using whatever address family the operating
1036 system feels like. Previous betas would try to use IPv4 as this
1037 is what most users expect, but this didn't work reliably on
1039 - In the action lists on CGI pages, actions and their parameters are
1040 no longer separated with a space. The action file parser doesn't
1041 actually allow this and will throw an invalid syntax error if actions
1042 and parameters in the action files are separated. Not adding the
1043 spaces means copy and pasting CGI output into the action files works.
1044 - The default keep-alive timeout has been reduced to 5 seconds to work
1045 around hangs in clients that treat the proxy like any other host and
1046 stop allowing any new connections if the "maximum number of
1047 connections per host" is reached.
1048 - Several webbug URLs that look like they are leading to images are now
1049 blocked as image instead of empty documents. Doing the latter causes
1050 WebKit-based clients to show a "missing image" icon which may mess up
1052 - The no-such-domain template is used for DNS resolution
1053 problems with FEATURE_IPV6_SUPPORT enabled. Previously the
1054 connect-failed template was used. Reported by 'zebul666'.
1055 - Accepts quoted expiration dates even though RFC 2109 10.1.2
1056 doesn't seem to allow them. Reported anonymously.
1057 - Don't try to forget connections if connection sharing is disabled.
1058 This wasn't a real problem but caused an unnecessary log message.
1059 - The still undocumented --enable-extended-host-patterns configure
1060 option has a better description.
1061 - Fixed an error message that would claim a write to the server
1062 failed when actually writing to the client failed.
1063 - Log the crunch reason before trying to write to the client.
1064 The log is easier to read that way.
1065 - Several log messages about client connections also mention
1067 - handle-as-empty-document no longer depends on the image blocking
1069 - Privoxy-Log-Parser is roughly 40% faster in highlighting mode.
1070 - uagen, a Firefox User-Agent generator for Privoxy and Mozilla
1071 browsers has been imported and is available in the tarball's
1073 - The scripts in the tools directory treat unknown parameters
1076 *** Version 3.0.15 beta ***
1078 - In case of missing server data, no error message is send to the
1079 client if the request arrived on a reused connection. The client
1080 is then supposed to silently retry the request without bothering
1081 the user. This should significantly reduce the frequency of the
1082 "No server or forwarder data received" error message many users
1084 - More reliable detection of prematurely closed client sockets
1085 with keep-alive enabled.
1086 - FEATURE_CONNECTION_KEEP_ALIVE is decoupled from
1087 FEATURE_CONNECTION_SHARING and now available on
1089 - Improved handling of POST requests on reused connections.
1090 Should fix problems with stalled connections after submitting
1091 form data with some browser configurations.
1092 - Fixed various latency calculation issues.
1093 - Allows the client to pass NTLM authentication requests to a
1094 forwarding proxy. This was already assumed and hinted to work
1095 in 3.0.13 beta but actually didn't. Now it's confirmed to work
1096 with IE, Firefox and Chrome.
1097 Thanks to Francois Botha and Wan-Teh Chang
1098 - Fixed a calculation problem if receiving the server headers
1099 takes more than two reads, that could cause Privoxy to terminate
1100 the connection prematurely. Reported by Oliver.
1101 - Compiles again on platforms such as OpenBSD and systems
1102 using earlier glibc version that don't support AI_ADDRCONFIG.
1103 Anonymously submitted in #2872591.
1104 - A bunch of MS VC project files and Suse and Redhat RPM spec
1105 files have been removed as they were no longer maintained for
1107 - Overly long action lines are properly rejected with a proper
1108 error message. Previously they would be either rejected as
1109 invalid or cause a core dump through abort().
1110 - Already timed-out connections are no longer temporarily remembered.
1111 They weren't reused anyway, but wasted a socket slot.
1112 - len refers to the number of bytes actually read which might
1113 differ from the ones received. Adjust log messages accordingly.
1114 - The optional JavaScript on the CGI page uses encodeURIComponent()
1115 instead of escape() which doesn't encode all characters that matter.
1116 Anonymously reported in #2832722.
1117 - Fix gcc45 warnings in decompress_iob().
1118 - Various log message improvements.
1119 - Privoxy-Regression-Test supports redirect tests.
1120 - Privoxy-Log-Parser can gather some connection statistics.
1122 *** Version 3.0.14 beta ***
1124 - The latency is taken into account when evaluating whether or not to
1125 reuse a connection. This should significantly reduce the number of
1126 connections problems several users reported.
1127 - If the server doesn't specify how long the connection stays alive,
1128 Privoxy errs on the safe side of caution and assumes it's only a second.
1129 - The error pages for connection timeouts or missing server data use a
1130 Last-Modified date in the past. Retry attempts are detected and Privoxy
1131 removes the If-Modified-Since header to prevent the server from responding
1132 with status code 304 in which case the client would reuse the error message.
1133 - Setting keep-alive-timeout to 0 disables keep-alive support. Previously
1134 Privoxy would claim to allow persistence but not reuse the connection.
1135 - Pipelined requests are less likely to be mistaken for the request
1136 body of the previous request. Note that Privoxy still has no real
1137 pipeline support and will either serialize pipelined requests or
1138 drop them in which case the client has to resent them.
1139 - Fixed a crash on some Windows versions when header randomization
1140 is enabled and the date couldn't be parsed.
1141 - Privoxy's keep-alive timeout for the current connection is reduced
1142 to the one specified in the client's Keep-Alive header.
1143 - For HTTP/1.1 requests, Privoxy implies keep-alive support by not
1144 setting any Connection header instead of using 'Connection: keep-alive'.
1145 - If the socket isn't reusable, Privoxy doesn't temporarily waste
1146 a socket slot to remember the connection.
1147 - If keep-alive support is disabled but compiled in, the client's
1148 Keep-Alive header is removed.
1149 - Fixed a bug on mingw32 where downloading large files failed if
1150 keep-alive support was enabled.
1151 - Fixed a bug that (at least theoretically) could cause log
1152 timestamps to be occasionally off by about a second.
1153 - No Proxy-Connection header if added if there already is one.
1154 - The configure script respects the $PATH variable when searching
1157 *** Version 3.0.13 beta ***
1159 - Added IPv6 support. Thanks to Petr Pisar who not only provided
1160 the initial patch but also helped a lot with the integration.
1161 - Added client-side keep-alive support.
1162 - The connection sharing code is only used if the connection-sharing
1164 - The max-client-connections option has been added to restrict
1165 the number of client connections below a value enforced by
1166 the operating system.
1167 - Fixed a regression reintroduced in 3.0.12 that could cause
1168 crashes on mingw32 if header date randomization was enabled.
1169 - Compressed content with extra fields couldn't be decompressed
1170 and would get passed to the client unfiltered. This problem
1171 has only be detected through statical analysis with clang as
1172 nobody seems to be using extra fields anyway.
1173 - If the server resets the Connection after sending only the headers
1174 Privoxy forwards what it got to the client. Previously Privoxy
1175 would deliver an error message instead.
1176 - Error messages in case of connection timeouts use the right
1178 - If spawning a child to handle a request fails, the client
1179 gets an error message and Privoxy continues to listen for
1180 new requests right away.
1181 - The error messages in case of server-connection timeouts or
1182 prematurely closed server connections are now template-based.
1183 - If zlib support isn't compiled in, Privoxy no longer tries to
1184 filter compressed content unless explicitly asked to do so.
1185 - In case of connections that are denied based on ACL directives,
1186 the memory used for the client IP is no longer leaked.
1187 - Fixed another small memory leak if the client request times out
1188 while waiting for client headers other than the request line.
1189 - The client socket is kept open until the server socket has
1190 been marked as unused. This should increase the chances that
1191 the still-open connection will be reused for the client's next
1192 request to the same destination. Note that this only matters
1193 if connection-sharing is enabled.
1194 - A TODO list has been added to the source tarball to give potential
1195 volunteers a better idea of what the current goals are. Donations
1196 are still welcome too: http://www.privoxy.org/faq/general.html#DONATE
1198 *** Version 3.0.12 ***
1200 - The socket-timeout option now also works on platforms whose
1201 select() implementation modifies the timeout structure.
1202 Previously the timeout was triggered even if the connection
1203 didn't stall. Reported by cyberpatrol.
1204 - The Connection: keep-alive code properly deals with files
1205 larger than 2GB. Previously the connection was closed too
1207 - The content length for files above 2GB is logged correctly.
1208 - The user-manual directive on the show-status page links to
1209 the documentation location specified with the directive,
1210 not to the Privoxy website.
1211 - When running in daemon mode, Privoxy doesn't log anything
1212 to the console unless there are errors before the logfile
1214 - The show-status page prints warnings about invalid directives
1215 on the same line as the directives themselves.
1216 - Fixed several justified (but harmless) compiler warnings,
1217 mostly on 64 bit platforms.
1218 - The mingw32 version explicitly requests the default charset
1219 to prevent display problems with some fonts available on more
1220 recent Windows versions. Patch by Burberry.
1221 - The mingw32 version uses the Privoxy icon in the alt-tab
1222 windows. Patch by Burberry.
1223 - The timestamp and the thread id is omitted in the "Fatal error"
1224 message box on mingw32.
1225 - Fixed two related mingw32-only buffer overflows. Triggering
1226 them required control over the configuration file, therefore
1227 this isn't seen as a security issue.
1228 - In verbose mode, or if the new option --show-skipped-tests
1229 is used, Privoxy-Regression-Test logs skipped tests and the
1232 *** Version 3.0.11 ***
1234 - On most platforms, outgoing connections can be kept alive and
1235 reused if the server supports it. Whether or not this improves
1236 things depends on the connection.
1237 - When dropping privileges, membership in supplementary groups
1238 is given up as well. Not doing that can lead to Privoxy running
1239 with more rights than necessary and violates the principle of
1240 least privilege. Users of the --user option are advised to update.
1241 Thanks to Matthias Drochner for reporting the problem,
1242 providing the initial patch and testing the final version.
1243 - Passing invalid users or groups with the --user option
1244 didn't lead to program exit. Regression introduced in 3.0.7.
1245 - The match all section has been moved from default.action
1246 to a new file called match-all.action. As a result the
1247 default.action no longer needs to be touched by the user
1248 and can be safely overwritten by updates.
1249 - The standard.action file has been removed. Its content
1250 is now part of the default.action file.
1251 - In some situations the logged content length was slightly too low.
1252 - Crunched requests are logged with their own log level.
1253 If you used "debug 1" in the past, you'll probably want
1254 to additionally enable "debug 1024", otherwise only passed
1255 requests will be logged. If you only care about crunched
1256 requests, simply replace "debug 1" with "debug 1024".
1257 - The crunch reason has been moved to the beginning of the
1258 crunch message. For HTTP URLs, the protocol is logged as well.
1259 - Log messages are shortened by printing the thread id on its
1260 own (as opposed to putting it inside the string "Privoxy()").
1261 - The config option socket-timeout has been added to control
1262 the time Privoxy waits for data to arrive on a socket.
1263 - Support for remote toggling is controlled by the configure
1264 option --disable-toggle only. In previous versions it also
1265 depended on the action editor and thus configuring with the
1266 --disable-editor option would disable remote toggling support
1268 - Requests with invalid HTTP versions are rejected.
1269 - The template symbol @date@ can be used to include a date(1)-like
1270 time string. Initial patch submitted by Endre Szabo.
1271 - Responses from shoutcast servers are accepted again.
1272 Problem reported and fix suggested by Stefan.
1273 - The hide-forwarded-for-headers action has been replaced with
1274 the change-x-forwarded-for{} action which can also be used to
1275 add X-Forwarded-For headers. The latter functionality already
1276 existed in Privoxy versions prior to 3.0.7 but has been removed
1277 as it was often used unintentionally (by not using the
1278 hide-forwarded-for-headers action).
1279 - A "clear log" view option was added to the mingw32 version
1280 to clear out all of the lines in the Privoxy log window.
1281 Based on a patch submitted by T Ford.
1282 - The mingw32 version uses "critical sections" now, which prevents
1283 log message corruption under load. As a side effect, the
1284 "no thread-safe PRNG" warning could be removed as well.
1285 - The mingw32 version's task bar icon is crossed out and
1286 the color changed to gray if Privoxy is toggled off.
1288 *** Version 3.0.10 ***
1290 - Ordinary configuration file changes no longer cause program
1291 termination on OS/2 if the name of the logfile hasn't been
1292 changed as well. This regression probably crept in with the
1293 logging improvements in 3.0.7. Reported by Maynard.
1294 - The img-reorder filter is less likely to mess up JavaScript code in
1295 img tags. Problem and solution reported by Glenn Washburn in #2014552.
1296 - The source tar ball now includes Privoxy-Log-Parser,
1297 a syntax-highlighter for Privoxy logs. For fancy screenshots see:
1298 http://www.fabiankeil.de/sourcecode/privoxy-log-parser/
1299 Documentation is available through perldoc(1).
1301 *** Version 3.0.9 beta ***
1303 - Added SOCKS5 support (with address resolution done by
1304 the SOCKS5 server). Patch provided by Eric M. Hopper.
1305 - The "blocked" CGI pages include a block reason that was
1306 provided as argument to the last-applying block action.
1307 - If enable-edit-actions is disabled (the default since 3.0.7 beta)
1308 the show-status page hides the edit buttons and explains why.
1309 Previously the user would get the "this feature has been disabled"
1310 message after using the edit button.
1311 - Forbidden CONNECT requests are treated like blocks by default.
1312 The now-pointless treat-forbidden-connects-like-blocks action
1314 - Not enabling limit-connect now allows CONNECT requests to all ports.
1315 In previous versions it would only allow CONNECT requests to port 443.
1316 Use +limit-connect{443} if you think you need the old default behaviour.
1317 - The CGI editor gets turned off after three edit requests with invalid
1318 file modification timestamps. This makes life harder for attackers
1319 who can leverage browser bugs to send fake Referers and intend to
1320 brute-force edit URLs.
1321 - Action settings for multiple patterns in the same section are
1322 shared in memory. As a result these sections take up less space
1323 (and are loaded slightly faster). Problem reported by Franz Schwartau.
1324 - Linear white space in HTTP headers will be normalized to single
1325 spaces before parsing the header's content, headers split across
1326 multiple lines get merged first. This should prevent problems like:
1327 * letting the session-cookies-only action slip
1328 some Cookies through unmodified,
1329 * only suppressing the first line of a header,
1330 thus creating an invalid one, and
1331 * to incorrectly block headers with valid timestamps
1332 that weren't properly recognized.
1333 Headers that could trigger these problems are unlikely to appear
1334 in "normal" web traffic, but could be intentionally generated to
1335 fool some of Privoxy's header parsers.
1336 - Host information is gathered outside the main thread so it's less
1337 likely to delay other incoming connections if the host is misconfigured.
1338 - New config option "hostname" to use a hostname other than
1339 the one returned by the operating system. Useful to speed-up responses
1340 for CGI requests on misconfigured systems. Requested by Max Khon.
1341 - The CGI editor supports the "disable all filters of this type"
1342 directives "-client-header-filter", "-server-header-filter",
1343 "-client-header-tagger" and "-server-header-tagger".
1344 - Fixed false-positives with the link-by-url filter and URLs that
1345 contain the pattern "/jump/".
1346 - The less-download-windows filter no longer messes
1347 "Content-Type: application/x-shockwave-flash" headers up.
1348 - In the show-url-info page's "Final results" section active and
1349 inactive actions are listed separately. Patch provided by Lee.
1350 - The GNUmakefile supports the DESTDIR variable. Patch for
1351 the install target submitted by Radoslaw Zielinski.
1352 - Embedding the content of configuration files in the show-status
1353 page is significantly faster now. For a largish action file (1 MB)
1354 a speedup of about 2450 times has been measured. This is mostly
1355 interesting if you are using large action files or regularly use
1356 Privoxy-Regression-Test while running Privoxy through Valgrind,
1357 for stock configuration files it doesn't really matter.
1358 - If zlib support is unavailable and there are content
1359 filters active but the prevent-compression action is disabled,
1360 the show-url-info page includes a warning that compression
1361 might prevent filtering.
1362 - The show-url-info page provides an OpenSearch Description that
1363 allows to access the page through browser search plugins.
1364 - Custom client-header filters that rewrite the request line
1365 incorrectly no longer cause Privoxy to crash. Reported by din_a4.
1366 - The obsolete kill-popups action has been removed as the
1367 PCRS-based popup filters can do the same and are slightly
1369 - The inspect-jpegs action has been removed.
1370 - The send-wafer and send-vanilla-wafer actions have been removed.
1371 They weren't particular useful and their behaviour could be emulated
1372 with add-header anyway.
1373 - Privoxy-Regression-Test has been significantly improved.
1374 - Most sections in the default.action file contain tests for
1375 Privoxy-Regression-Test to verify that they are working as intended.
1376 - Parts of Privoxy have been refactored to increase maintainability.
1377 - Building with zlib (if available) is done by default.
1379 *** Version 3.0.8 ***
1381 - Fixed a small memory leak when listen-address only specifies the port.
1382 - The source tar balls now include Privoxy-Regression-Test which
1383 (upon other things) can be used to automatically detect some
1384 packaging problems. Packagers are welcome to give it a try.
1385 - Reverted a change in 3.0.7 that caused path patterns to be checked
1386 even if the host pattern match already failed. While this doesn't
1387 noticeable affect the performance, it makes it less likely to run
1388 out of stack space with overly-complex path patterns the user might
1390 - Updated the msn, yahoo and google filters to work as advertised again.
1391 - The warning message shown by the show-status CGI page is easier to
1392 understand. Previously it wasn't clear that the error message
1393 is shown below the invalid directive. (Reported by Lee)
1394 - When regenerating Content-Disposition headers the more common
1395 spelling is used for the name. Previously it was written without caps.
1396 - Less confusing log message if the content type isn't overwritten
1397 because force-text-type wasn't used but the old type doesn't look
1398 like content that would be filtered normally.
1399 - Better log messages if the user tries to execute filters that
1401 - Treat the non-standard Request-Range headers like standard range
1402 headers and suppress them if content filtering is enabled.
1403 - Prevent the log messages for CONNECT requests to unacceptable
1404 ports from printing the limit-connect argument as [null] if
1405 limit-connect hasn't been explicitly enabled.
1406 - Don't disable the mingw32 log window if the logfile directive
1407 isn't used. While it was an intentional change in 3.0.7 at least
1408 one user perceived it as a regression and the same effect can
1409 be achieved by disabling all debug directives.
1410 - Fixed two minor problems related to the win32 build process: a css
1411 file was not being in the installer and the trustfile comment in the
1412 config.txt referenced a nonexisting file
1413 - Minor documentation fixes.
1415 *** Version 3.0.7 beta ***
1417 - Added zlib support to filter content with gzip and deflate
1418 encoding. (Patch provided by Wil Mahan)
1419 - Dedicated filters and actions are used for header filtering.
1420 "filter-client-headers" and "filter-client-headers" are no longer
1421 supported, use server-header-filter{} and client-header-filter{}
1423 - Tags can be used to change actions based on HTTP headers.
1424 - New server-header filter: less-download-windows.
1425 - New client-header taggers: css-requests, image-requests,
1426 client-ip-address, http-method, allow-post, complete-url,
1427 user-agent and privoxy-control.
1428 - New server-header taggers: content-type and privoxy-control.
1429 - The forward-override{} action allows to change the forwarding
1430 settings through the action files, for example based on client
1431 headers like the User-Agent, or the request origin.
1432 - Socks errors are no longer handled by the CGI page for
1433 DNS resolution failures.
1434 - CGI pages use favicons to signal whether they are error
1435 or control pages. This is useful if you rely heavily on
1437 - The show-url-info CGI page shows the forwarding settings.
1438 - "Crunch!" log messages (used when Privoxy answers requests
1439 by itself) now also contain the reason.
1440 - Allow to rewrite the request destination behind the client's back.
1441 - Fix socks requests on big-endian platforms. Patch provided by Song Weijia.
1442 - Fixes possible deadlocks and crashes on OpenBSD.
1443 Patch provided by Ralf Horstmann.
1444 - The CGI action editor allows to edit actionfiles with previously
1445 forbidden characters like dots.
1446 - New trust entries are saved with a comment that contains the
1447 trusted referring URL (Suggested by Daniel Griscom).
1448 - Filter descriptions are HTML encoded automatically.
1449 - New config option "split-large-forms" to work
1450 around a browser bug that caused IE6 and IE7 to ignore
1451 the Submit button on the edit-actions-for-url CGI page.
1452 - New config option "allow-cgi-request-crunching" to allow
1453 requests for Privoxy's CGI pages to be blocked, redirected
1454 or (un)trusted like ordinary requests.
1455 - Empty filter files no longer interrupt the filtering process
1456 prematurely and are correctly listed on the show-status CGI page.
1457 - New config option "accept-intercepted-requests" to combine
1458 Privoxy with any packet filter to build an intercepting proxy
1459 for HTTP/1.1 requests (and for HTTP/1.0 requests with Host header set).
1460 - fast-redirects{} catch redirects to https URLs as well.
1461 - redirect{s@foo@bar@} can be used to redirect to a rewritten
1462 version of the original URL.
1463 - Trap unsupported gopher proxy requests.
1464 - Fixed a bug in the User Manual delivery on Windows
1465 (mingw32 only). Images now show up correctly and HTML
1466 pages are no longer padded with garbage data.
1467 - Fixed several minor memory leaks, most of them discovered with Valgrind.
1468 - Only unlink the pidfile if it's actually used.
1469 - Retries after connection problems with forced requests
1470 aren't blocked again.
1471 - On Unix SIGABRT causes a core dump as expected and is no
1472 longer treated as normal shutdown signal.
1473 - The "access denied" CGI page is more descriptive and
1474 allows retries to circumvent the referrer check.
1475 - Updated PCRS to handle unexpected PCRE errors properly.
1476 Fixed crashes that could occur if Privoxy was build
1477 with external PCRE versions newer than Privoxy's internal
1478 one. (Reported by Chung-chieh Shan)
1479 - Fixed crashes with null bytes in PCRS replacement strings
1480 (Patch provided by Felix Gröbert).
1481 - Fixed crashes with header time randomization on mingw32.
1482 - The CGI style sheet is no longer delivered if the referring
1483 page isn't a Privoxy CGI page. This prevents a JavaScript-based
1484 Privoxy detection "attack". Note that detecting Privoxy is
1485 still possible through other ways and Privoxy was never intended
1486 to be invisible anyway.
1487 - Added support for AmigaOS 4, fixed build for AmigaOS 3.x.
1488 - The show-url-info CGI page displays a warning if Privoxy
1489 is currently toggled off.
1490 - The show-status CGI page suppresses the edit button
1491 for action files if Privoxy has no write access.
1492 - Most CGI error pages react properly to HEAD requests.
1493 - Requests with RFC 3253 HTTP methods (used by Subversion)
1494 are accepted. (Patch provided by Petr Kadlec)
1495 - New config option "templdir" to change the location
1496 of the CGI templates to make sure customized templates
1498 - Better handling of "HTTP/1.1 100 Continue" responses.
1499 - The background of the PNG pattern is transparent.
1500 - Fixed XML syntax errors caused by banners-by-size and banners-by-url.
1501 - Fixed crashes and possible action file corruptions
1502 when lines containing hashes are written through the CGI editor.
1503 - Supports dynamic filters which can contain variables.
1504 - Supports tags to change the actions based on client or server headers.
1505 - Incorrect actions are logged before program termination.
1506 - The "actionsfile" syntax in the configuration file is consistent
1507 with the rest of the configuration options and requires the
1508 whole file name. This is an incompatible change, if you use
1509 an old configuration file you might have to append ".action"
1510 to your "actionsfile" directives.
1511 - With the configuration file option "enforce-blocks" the
1512 "go there anyway" mechanism can be disabled without recompiling
1514 - More precise error messages in case of incorrect acl syntax.
1515 - Logs a warning if filtering is enabled but impossible due
1516 to lack of zlib support or use of the prevent-compression action.
1517 - Less noisy handling of Cookie:" and "Connection:" headers.
1518 - Improved error messages in case of connection problems.
1519 - Fix a command-line-parsing bug that was introduced before 3.0.5
1520 beta and caused Privoxy to treat the last argument as configuration
1521 file if no configuration file was specified.
1522 - Treat unknown command line options as fatal errors instead
1523 of silently ignoring them.
1524 - Use string functions with length checks more often.
1525 - Don't log CONNECT requests twice.
1526 - Allow to log the source address for ACL-related connection drops.
1527 - Don't ignore applying filters if the server didn't
1528 specify a Content-Type. Bug reported by Amuro Namie.
1529 - Rejected CONNECT requests are logged with log level info
1530 (enabled by default) and the reason for the block.
1531 - New command line option "--pre-chroot-nslookup hostname" to
1532 intialize the resolver library before chroot'ing. On some systems this
1533 reduces the number of files that must be copied into the chroot tree.
1534 (Patch provided by Stephen Gildea)
1535 - Fix a long-standing memory corruption bug that could cause
1536 Privoxy to overwrite a single byte in memory it didn't explicitly
1537 allocate (but that probably was allocated anyway due to bucket size).
1538 - Send template-based CGI pages as HTTP/1.1 unless the client
1540 - Let the first line in connection established responses
1541 end in \r\n as required by RFC1945. Reported by Bert van Leeuwen.
1542 - If no log file has been specified, disable logging instead of logging
1544 - Don't block stderr when in daemon mode.
1545 - Ignore missing zero-chunks when filtering chunk-encoded content.
1546 Earlier Privoxy versions would buffer and then forward the content
1547 unmodified which caused some browsers to simply show empty pages.
1548 - Fix double free in cgi_edit_actions_list(). Reported by Venustech AD-LAB.
1549 - The code to add X-Forwarded-For headers when the hide-forwarded-for-headers
1550 action isn't being used has been removed.
1551 - Fixed trustfile feature which previously didn't work without FEATURE_TOGGLE.
1553 - Minor code clean-ups, filter and action file updates.
1554 (Some of them reported by Davide Alberani, Markus Elfring,
1555 Stefan Huehner and Adam Piggott)
1557 *** Version 3.0.6 ***
1559 - New content filters: no-ping, google, msn, yahoo and blogspot.
1560 - New header filters: x-httpd-php-to-html, html-to-xml, xml-to-html
1561 and hide-tor-exit-notation.
1562 - The special header "X-Filter: No" now disables header filtering as well.
1563 - Improved the filters img-reorder, js-annoyances, webbugs,
1564 banners-by-size, banners-by-link and ie-exploits to make them
1565 less likely to break anything.
1566 - Removed outdated URL patterns in default.action and added new ones.
1567 - Added redirection from http://p.p/user-manual to http://p.p/user-manual/
1568 - Changed webinterface default values for hide-user-agent, hide-referrer
1569 and set-image-blocker.
1571 *** Version 3.0.5 beta ***
1573 - Windows version can be installed/started as a service.
1574 - Windows icon stays blue when Privoxy is idle, green when busy.
1575 - Integrated Fabian Keil's extensive patch. See:
1576 http://www.fabiankeil.de/sourcecode/privoxy/. Includes the
1577 following new or significantly improved actions (among many
1578 other improvements):
1580 content-type-overwrite{}
1581 crunch-client-header{string}
1582 crunch-if-none-match
1583 crunch-server-header{string}
1584 fast-redirects{check-decoded-url}
1585 filter-client-headers
1586 filter-server-headers
1588 handle-as-empty-document
1589 hide-accept-language{}
1590 hide-content-disposition{}
1591 hide-if-modified-since
1592 hide-referrer{conditional-block}
1593 overwrite-last-modified{}
1595 treat-forbidden-connects-like-blocks
1597 - Standard-compliant clients are prevented from displaying cached
1598 copies of Privoxy's error messages after the cause of the problem
1600 - Improved DNS error handling.
1601 - Multiple filter files can now be specified in config.
1602 - Added jpeg filtering to defend against MS jpeg vulnerability MS04-028
1603 with the new inspect-jpegs action.
1604 - Removed the "arbitrary" 1000 filter limit - addresses tracker #911950
1605 - Thanks to Jindrich Makovicka for a race condition fix for the log
1606 file. The race condition remains for non-pthread implementations.

1616 (for trustfile users).
1618 *** Version 3.0.3 ***
1620 - Fixed yet another two memory leaks. Process growth seems stopped now.
1621 - Further tightened security against malicious toggle-off links.
1622 - Excluded text/plain MIME types from filtering. This fixes a
1623 couple of client-crashing, download corruption and
1624 Privoxy performance issues, whose root cause lies in
1625 web servers labelling content of unknown type as text/plain.
1626 - Assorted fixes for POSIX compliance, signal handling, graceful
1627 termination, compiler warnings, OSX support, Win32 systray,
1628 error logging, hostname wildcards, correct detection of NetBSD.
1629 - Workarounds for client (iTunes etc) and server (PHP < 4.2.3) bugs
1630 including the notorious "blank page" problem.
1631 - Various filter improvements; most notably the unsolicited-popups
1632 filter became less destructive

1639 - Fixed bug in domain name matching
1640 - Assorted small fixes (Win32 menu, CGI URL editor, ..)
1641 - Added basic support for the OPTIONS and TRACE http methods
1642 - Added workaround for Bug in Mac OSX that made Privoxy crash occasionally
1643 - Refined the default action file through >400 items of user feedback
1645 - Assorted refinements, optimizations and fixes in the js-annoyances,
1646 img-reorder, banners-by-size, banners-by-link, webbugs, refresh-tags,
1647 html-annoyances, content-cookies and fun filters
1648 - Replaced filter "popups" by choice between two modes:
1649 - "unsolicited-popups" tries to catch only the unsolicited ones
1650 - "all-popups" tries to kill them all (as before)
1651 - New filter "tiny-textforms" Help those tiny or hard-wrap textareas.
1652 - New filter "jumping-windows" that prevents windows from resizing
1653 and moving themselves
1654 - New filter "demoronizer" which fixes MS's abuse of std charsets
1655 (common cases anyway).
1656 - Replaced "nimda" with more general "ie-exploits" filter in which
1657 all filters for exploits shall be collected
1658 - Improved cookie logging
1659 - Rewrote make install target. Added uninstall and install-strip
1661 - Fixed a potential (application-level, NOT OS-level!) security
1662 problem involving remote toggling and action file manipulation
1663 by mailicious websites.
1664 - Added ability to chroot (thanks to Sviatoslav Sviridov)
1665 - Added more action aliases for prehistoric action names
1666 - Add Slackware support to Makefile.
1670 - Fixed Windows startmenu items, log window and tray icon menus.
1671 - Added warning for bogus install target

1675 - Add a user contrib module to cvs:
1676 http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/ijbswa/contrib/
1678 *** Version 2.9.18 ***

1681 - Bugfix: String actions now reliably editable through CGI interface
1682 - Three filters fixed (again!)
1683 - Assorted small fixes and doc enhancements
1685 *** Version 2.9.16 ***
1687 - Major revamp of default.action to get rid of years of cruft.
1688 - Same for default.filter
1689 - Re-design and major improvements to the CGI editor interface.
1690 - Address spurious 'out of memory' error due to incorrect file permissions.
1691 - Impose buffer limits while reading client and server headers.
1692 - Better memory and CPU optimization.
1693 - Add Conectiva Linux package.
1694 - user-manual directive added to config for help links from within CGI
1696 - Multiple actions files can now be specified in config.
1697 - Actions files are changed to: default.action, standard.action, and
1698 user.action. user.action is for personal/local configuration.

1708 - Various tweaks for actions file to get ready for stable 3.0
1709 - Included a 'Bookmarklet' and PHP scripts for reporting actions file
1710 problems via web interface at privoxy.org. Accessed via internal CGIs.
1711 - Include cgi-style.css for templates.
1712 - #include mechansim for common text in templates
1713 - Various other minor fixes.
1715 *** Version 2.9.13 beta ***
1717 - *NEWS*: The project has been renamed to Privoxy! The new name is
1718 reflected throughout (file locations, etc).
1719 - ijb.action is now default.action. re_filterfile is now
1721 - http://i.j.b/ is now http://p.p/
1722 - The 'logo' option for replacing ad iamges is removed now. 'Pattern'

1727 *** Version 2.9.12 beta ***
1729 - **READ**: The default listening PORT is NOW 8118!!! Changed from
1730 8000 due to conflict with NAS (Network Audio Server, whatever that
1732 - More CGI actions editor fixes and improvements.
1733 - Win32 command line fix ups.
1734 - re_filterfile now has modular sections that can be activated on a
1735 per site basis. Some new goodies there too.
1736 - +filter now takes arguments to match FILTER sections in re_filterfile
1737 for even more flexibility.
1738 - Added a new image blocker option: +image-blocker{pattern}, which
1739 displays a checkerboard patthern and scales better than the logo.
1740 - PNG images will be used in place of GIF for JB built-in images
1741 if configured with --enable-no-gif.
1742 - Clean up compiler warnings (mostly).
1743 - Improved handling of failed DNS lookups & diagnostics for failed bind

1748 - CGI Editor works on OS/2 now.
1749 - Fix restart failure where sockets were in TIME_WAIT.
1750 - Fixes for actions cgi editor, make sure we have right file.
1751 - A --pidfile command line option now, in addition to --help,
1752 --version, --no-daemon, --user and configfile. --no-daemon replaces
1753 the former -d option and _DEBUG define. --user will drop privileges
1754 to the specified user.

1768 - Checks for correct header length.
1769 - Fix user:pass@host.domain.com auth bug.
1770 - Better signal handling on *nix.
1771 - Fix CFLAGS hard-coded in configure.in
1772 - Fix threading bug re: gethostbyname() that caused random
1773 URLs to fail in some cases.
1776 *** Version 2.9.11 Alpha Changes ***
1778 - A web-based editor for the actions file is included (go to http://i.j.b/).
1779 - Web-based toggle IJB on/off support.
1780 - Cookie handling has changed - the new +no-cookies-keep feature is now the
1782 - actionsfile is renamed to ijb.action.
1783 - junkbstr.txt is now config.txt on Win32.
1784 - Support for running IJB as a UNIX daemon process has improved.
1785 - Unix daemon now returns error code on failed start.
1786 - Timestamps in logfile and jarfile now.

1789 - Many other minor bugfixes
1790 - Start a ChangeLog :)
1794 *** Version 2.9.3 pre-Alpha Changes ***
1796 - Amiga support (completely untested by me - I don't have an Amiga)
1797 - "tinygif 3" support (redirects blocked images to a specified URL, so
1798 the browser doesn't have to load and cache many copies of the same
1800 - one case where there were both local and global "referrer" variables
1801 (yuck!) clarified by renaming the local one to "refer".
1802 - Fixed some places where close() was used instead of close_socket().
1803 Thanks to Jörg Strohmayer (joergs at users.sourceforge.net) for these.
1804 - Temporary hack to get FORCE_LOAD to work with IE. I just lowercased the
1805 FORCE_LOAD_PREFIX. Needs fixing properly.
1806 - Most URLs hardcoded into Junkbuster were changed to go through a script
1807 e.g. http://ijbswa.sourceforge.net/redirect.php?v=2.9.3&to=faq
1808 The only other URLs left are the GNU GPL:
1809 http://www.fsf.org/copyleft/gpl.html
1811 http://ijbswa.sourceforge.net/
1812 ... and various URLs which will be intercepted by Junkbuster anyway.
1813 TODO: Still need to do something with the URLs in Junkbuster Corp's
1814 copyright/trademark notice on the bottom of the show-proxy-args page.
1815 - PCRE or GNU Regex is now a #define option.
1818 *** Version 2.9.2 pre-Alpha Changes ***
1820 - Andreas applied the latest version of the FORCE patch.
1823 *** Version 2.9.1 pre-Alpha Changes ***
1825 - in parsers.c, fixed two #ifdef FORCE to #ifdef FORCE_LOAD
1826 (BTW: I think FORCE is precise enough, since loading remote
1827 data is the whole purpose of a proxy..)
1828 - Set the FORCE_PREFIX (back) to 'IJB-FORCE-LOAD-'. While 'noijb.'
1829 is more elegant and looks like a hostname in the URL, it doesn't
1830 make clear to the inexperienced user that the proxy is bypassed. It
1831 also has a higher name collision risk.
1832 - Filled in the function header templates for my functions in
1833 parsers.c (again). They obviously got lost in our current
1835 - Cut the credit for the §-referrer-option from the config file,
1836 that Stefan had placed there.
1837 - Improved the re_filterfile
1840 *** Version 2.9.0 pre-Alpha Changes ***
1842 - Now use PCRE, not GNU REGEX. I have not yet had chance to check the
1843 syntax of the block/image/cookie file to ensure that they match what
1844 is expected - however they seem to work.
1845 - Replaced "configure" script with one generated by "autoconf". Also
1846 use a header "config.h" (was ijbconfig.h in my previous release) for
1847 the #defines. "config.h" is now generated with "autoheader" from
1848 "acconfig.h" and "configure.in". (Note that to install you do not
1849 need autoconf or autoheader - just run "./configure".)
1850 To see command-line options, run "./configure --help".
1851 This is my first ever autoconf script, so it has some rough edges
1852 (how PCRE is handled is the roughest).
1853 - Error logging code replaced with new module errlog.c, based on the
1854 one from JunkbusterMT (but with the threading code removed).
1855 - Most of Rodney's 0.21 and 0.21A patches applied. (Marked *). I did not
1856 apply all of these, since I had already independently done conditional
1857 popup file, conditional image file, and integration of popup code.
1858 - ACL, Jar and trust files conditionally compiled.
1859 - New source file headers.
1860 - Various cosmetic changes. (But I have not consistently ordered the
1861 config files - I think that's worthwhile, but it's 1am and I want to
1863 - RCS tags on .h files.
1864 - RCS tags are const char[] rather than const char *. (Saves 4 bytes
1866 - VC++ project files renamed to vc_junkbuster.*.
1867 - show-proxy-args now shows status of all conditionals, not just REGEX
1868 - Various functions moved around. Most notably all the system-specific
1869 sockets code which was spread between jcc.c, bind.c, and connect.c,
1870 has been moved to "jbsockets.c". The non-system-specific code from
1871 connect.c and socks4.c has been movet to "gateway.c". Also, the
1872 config file loader and the global variables it writes to have been
1873 moved to "loadcfg.c". (Maybe this should go into loaders.c?)
