4 *** Version 3.0.18 Stable ***
7 - Fix a logic bug that could cause Privoxy to reuse a server
8 socket after it got tainted by a server-header-tagger-induced
9 block that was triggered before the whole server response had
10 been read. If keep-alive was enabled and the request following
11 the blocked one was to the same host and using the same forwarding
12 settings, Privoxy would send it on the tainted server socket.
13 While the server would simply treat it as a pipelined request,
14 Privoxy would later on fail to properly parse the server's
15 response as it would try to parse the unread data from the
16 first response as server headers for the second one.
17 Regression introduced in 3.0.17.
18 - When implying keep-alive in client_connection(), remember that
19 the client didn't. Fixes a regression introduced in 3.0.13 that
20 would cause Privoxy to wait for additional client requests after
21 receiving a HTTP/1.1 request with "Connection: close" set
22 and connection sharing enabled.
23 With clients which terminates the client connection after detecting
24 that the whole body has been received it doesn't really matter,
25 but with clients that don't the connection would be kept open until
27 - Fix a subtle race condition between prepare_csp_for_next_request()
28 and sweep() A thread preparing itself for the next client request
29 could briefly appear to be inactive.
30 If all other threads were already using more recent files,
31 the thread could get its files swept away under its feet.
32 So far this has only been reproduced while stress testing in
33 valgrind while touching action files in a loop. It's unlikely
34 to have caused any actual problems in the real world.
36 - General improvements:
37 - Privoxy can (re)compress buffered content before delivering
38 it to the client. Disabled by default as most users wouldn't
40 - The +fast-redirects{check-decoded-url} action checks URL
41 segments separately. If there are other parameters behind
42 the redirect URL, this makes it unnecessary to cut them off
43 by additionally using a +redirect{} pcrs command.
44 Initial patch submitted by Jamie Zawinski in #3429848.
45 - When loading action sections, verify that the referenced filters
46 exist. Currently missing filters only result in an error message,
47 but eventually the severity will be upgraded to fatal.
48 - Allow to bind to multiple separate addresses.
49 Patch set submitted by Petr Pisar in #3354485.
50 - Set socket_error to errno if connecting fails in rfc2553_connect_to()
51 Previously rejected direct connections could be incorrectly reported
53 - Disable filters if SDCH compression is used unless filtering is forced.
54 If SDCH was combined with a supported compression algorithm,
55 we'd previously try to decompress it, when successful apply
56 the enabled filters and ditch the Content-Encoding header
57 even though the SDCH compression wasn't removed.
58 Reported by zebul666 in #3225863.
59 - Properly deal with FEATURE_TOGGLE being disabled
60 - Adjust url_code_map[] so spaces are replaced with %20 instead of '+'
61 While '+' can be used by client's submitting form data, this is not
62 actually what Privoxy is using the lookups for. This is more of a
63 cosmetic issue and doesn't fix any actual problems.
64 - When compiled without FEATURE_FAST_REDIRECTS, do not silently
65 ignore +fast-redirect{} directives
66 - Added a workaround for GNU libc's strptime() reporting negative
67 year values when the parsed year is only specified with two digits.
68 On affected systems cookies with such a date would not be turned
69 into session cookies by the +session-cookies-only action.
70 Reported by Vaeinoe in #3403560
71 - Fixed bind failures with certain GNU libc versions if no non-loopback
72 IP address has been configured on the system. This is mainly an issue
73 if the system is using DHCP and Privoxy is started before the network
74 is completely configured.
75 Reported by Raphael Marichez in #3349356.
76 Additional insight from Petr Pisar.
77 - Privoxy log messages now use the ISO 8601 date format %Y-%m-%d.
78 It's only slightly longer than the old format, but contains
79 the full date including the year and allows sorting by date
80 (when grepping in multiple log files) without hassle.
81 - Make a copy of the --user value and only mess with that when splitting
82 user and group. On some operating systems modifying the value directly
83 is reflected in the output of ps and friends and can be misleading.
84 Reported by zepard in #3292710.
85 - If forwarded-connect-retries is set, only retry if the we are actually
86 forwarding the request. Previously direct connections would be retried
88 - Fixed a small memory leak when retrying connection
89 - Remove an incorrect assertion in compile_dynamic_pcrs_job_list()
90 It could be triggered by a pcrs job with an invalid pcre
91 pattern (for example one that contains a lone quantifier).
92 - In get_last_url(), do not bother trying to decode URLs that do
93 not contain at least one '%' sign. It reduces the log noise and
94 a number of unnecessary memory allocations.
95 - If the --user argument user[.group] contains a dot,
96 always bail out if no group has been specified.
97 Previously the intended, but undocumented (and apparently
98 untested), behaviour was to try interpreting the whole
99 argument as user name, but the detection was flawed and
100 checked for '0' isntead of '\0', thus merely preventing
101 group names beginning with a zero.
102 - Simplify the signal setup in main()
103 - Streamline socks5_connect() slightly
104 - In case of SOCKS5 failures, dump the socks response
105 - In socks5_connect(), require a complete socks response from the server
106 Previously we didn't care how much data the server response
107 contained as long as the first two bytes contained the expected
109 While at it, shrink the buffer size so we can't read more
110 than a whole socks response. This is required to support
111 Tor's optimistic data extension.
112 - In chat(), do not bother to generate a client request in case of
113 direct CONNECT requests
114 - Reduce server_last_modified()'s stack size
115 - Shorten get_http_time() by using strftime()
116 - Constify the known_http_methods pointers in unknown_method()
117 - Constify the time_formats pointers in parse_header_time()
118 - Constify the formerly_valid_actions pointers in action_used_to_be_valid()
119 - In html_code_map[], use a numeric character reference instead of '
120 which wasn't standardized before XHTML 1.0
121 - Introduce a GNUMakefile MAN_PAGE variable that defaults to privoxy.1.
122 The Debian package uses section 8 for the man page and this
123 should simplify the patch.
124 - Deduplicate the INADDR_NONE definition for Solaris by moving it to jbsockets.h
125 - In block_url(), ditch the obsolete workaround for ancient Netscape versions
126 that supposedly couldn't properly deal with status code 403.
127 - Remove a useless NULL pointer check in load_trustfile()
128 - Remove two useless NULL pointer checks in load_one_re_filterfile().
129 - Change url_code_map[] from an array of pointers to an array of arrays
130 It removes an unnecessary layer of indirection and on
131 64bit system reduces the size of the binary a bit.
133 Fixes taken from Debian's 29_typos.dpatch by Roland Rosenfeld.
134 - Add a dok-tidy GNUMakefile target to clean up the messy HTML
135 generated by the other dok targets.
136 - GNUisms in the GNUMakefile have been removed.
137 - Change the HTTP version in static responses to 1.1
138 - Synced config.sub and config.guess with upstream
139 2011-11-11/386c7218162c145f5f9e1ff7f558a3fbb66c37c5.
140 - Add a dedicated function to parse the values of toggles
141 Reduces duplicated code in load_config() and provides
142 better error handling. Invalid or missing toggle values
143 are now a fatal error instead of being silently ignored.
144 - Terminate HTML lines in static error messages with \n instead of \r\n.
145 - Simplify cgi_error_unknown() a bit.
146 - In LogPutString(), don't bother looking at pszText when not
147 actually logging anything
148 - Change ssplit()'s fourth parameter from int to size_t.
149 Fixes a clang complaint.
150 - Add a warning that the statistics currently can't be trusted.
151 Mention Privoxy-Log-Parser's --statistics option as
152 an alternative for the time being.
153 - In rfc2553_connect_to(), start setting cgi->error_message on error
154 - Change the expected status code returned for http://p.p/die depending
155 on whether or not FEATURE_GRACEFUL_TERMINATION is available.
156 - In cgi_die(), mark the client connection for closing.
157 If the client will fetch the style sheet through another connection
158 it gets the main thread out of the accept() state and should thus
159 trigger the actual shutdown.
160 - Add a proper CGI message for cgi_die().
161 - Fix an invalid free when compiled with FEATURE_GRACEFUL_TERMINATION
162 and shut down through http://config.privoxy.org/die
163 - Don't enforce a logical line length limit in read_config_line()
164 - Slightly refactor server_last_modified() to remove useless gmtime*() calls
165 - In get_content_type(), also recognize '.jpeg' as JPEG extension
166 - Add '.png' to the list of recognized file extenstions in get_content_type()
167 - In block_url(), consistently use the block reason "Request blocked by Privoxy"
168 In two places the reason was "Request for blocked URL" which
169 hides the fact that the request got blocked by Privoxy and
170 isn't necessarly correct as the block may be due to tags.
171 - In get_actions(), fix the "temporary" backwards compatibility hack
172 to accept block actions without reason.
173 It also covered other actions that should be rejected as invalid.
174 Reported by Billy Crook.
175 - In listen_loop(), reload the configuration files after accepting
176 a new connection instead of before.
177 Previously the first connection that arrived after a configuration
178 change would still be handled with the old configuration.
179 - In chat()'s receive-data loop, skip a client socket check if
180 the socket will be written to right away anyway. This can
181 increase the transfer speed for unfiltered content on fast
183 - The socket timeout is used for SOCKS negotiation as well.
184 - Don't keep the client connection alive if any configuration file
185 changed since the time the connection came in.
186 This is closer to Privoxy's behaviour before keep-alive support
187 for client connection has been added and also less confusing in
189 - Treat all Content-Type header values containing the pattern
190 'script' as a sign of text. Reported by pribog in #3134970.
193 - Action file improvements:
195 - Moved the site-specific block pattern section below the one for the
196 generic patterns so for requests that are matched in both, the block
197 reason for the domain is shown which is usually more useful than showing
198 the one for the generic pattern.
199 - Remove -prevent-compression from the fragile alias
200 It's no longer used anywhere by default and isn't
201 known to break stuff anyway.
202 - Add a (disabled) section to block various Facebook tracking URLs
203 Reported by Dan Stahlke in #3421764.
204 - Add a (disabled) section to rewrite and redirect click-tracking
205 URLs used on news.google.com
206 Reported by Dan Stahlke in #3421755.
207 - Unblock linuxcounter.net/
208 Reported by Dan Stahlke in #3422612.
209 - Block 'www91.intel.com/' which is used by Omniture.
210 Reported by Adam Piggott in #3167370.
211 - Disable the handle-as-empty-doc-returns-ok option and mark it as deprecated.
212 Reminded by tceverling in #2790091.
213 - Add ".ivwbox.de/" to the "Cross-site user tracking" section.
214 Reported by Nettozahler in #3172525.
215 - Unblock and fast-redirect ".awin1.com/.*=http://"
216 Reported by Adam Piggott in #3170921.
217 - Block "b.collective-media.net/".
218 - Widen the Debian popcon exception to "qa.debian.org/popcon".
219 Seen in Debian's 05_default_action.dpatch by Roland Rosenfeld.
220 - Block ".gemius.pl/" which only seems to be used for user tracking.
221 Reported by johnd16 in #3002731. Additional input from Lee and movax.
222 - Disable banners-by-size filters for '.thinkgeek.com/'
223 The filter only seems to catch pictures of the inventory.
224 - Block requests for 'go.idmnet.bbelements.com/please/showit/'
225 Reported by kacperdominik in #3372959.
226 - Unblock adainitiative.org/
227 - Add a fast-redirects exception for '.googleusercontent.com/.*=cache'
228 - Add a fast-redirects exception for webcache.googleusercontent.com/
229 - Unblock http://adassier.wordpress.com/ and http://adassier.files.wordpress.com/
231 - Filter file improvements:
232 - Let the yahoo filter hide '.ads'
233 - Let the msn filter hide overlay ads for Facebook 'likes' in search results.
234 - Let the msn filter hide elements with the id 's_notf_div'.
235 They only seem to be used to advertise site 'enhancements'.
236 - Let the js-events filter additionally disarm setInterval()
237 Suggested by dg1727 in #3423775.
239 - Documentation improvements:
240 - Clarify the effect of compiling Privoxy with zlib support
241 Suggested by dg1727 in #3423782.
242 - Point out that the SourceForge messaging system works
243 like a blackhole and should thus not be used to contact
244 individual developers.
245 - Mention some of the problems one can experience when not
246 explicitly configuring an IP addresses as listen address.
247 - Explicitly mention that hostnames can be used instead of
248 IP addresses for the listen-address, that only the first
249 address returned will be used and what happens if the
251 Requested by Calestyo in #3302213.
253 - Log message improvements:
254 - If only the server connection is kept alive, do not pretent to
255 wait for a new client request.
256 - Remove a superfluos log message in forget_connection()
257 - In chat(), properly report missing server responses as such
258 instead of calling them empty
259 - In forwarded_connect(), fix a log message nobody should ever see
260 - Fix a log message in socks5_connect(), a failed write operation
261 was logged as failed read operation
262 - Let load_one_actions_file() properly complain about a missing
263 '{' at the beginning of the file
264 Simply stating that a line is invalid isn't particularly helpful.
265 - Do not claim to listen on a socket until we actually do.
266 Patch submitted by Petr Pisar #3354485
267 - Prevent a duplicated LOG_LEVEL_CLF message when sending out
268 the "no-server-data" response
269 - Also log the client socket when dropping a connection.
270 - Include the destination host in the 'Request ... marked for
271 blocking. limit-connect{...} doesn't allow CONNECT ...' message
272 Patch submitted by Saperski in #3296250.
273 - Prevent a duplicated log message if none of the resolved IP
274 addresses were reachable
275 - In connect_to(), do not pretend to retry if forwarded-connect-retries
277 - When a specified user or group can't be found, put the name in
278 single-quotes when logging it.
279 - In rfc2553_connect_to(), explain getnameinfo() errors differently.
280 - Remove a useless log message in chat()
281 - When retrying to connect, also log the maximum number of connection
283 - Rephrase a log message in compile_dynamic_pcrs_job_list()
284 Divide the error code and its meaning with a colon.
285 Call the pcrs job dynamic and not the filter. Filters may
286 contain dynamic and non-dynamic pcrs jobs at the same time.
287 Only mention the name of the filter or tagger, but don't
288 claim it's a filter when it could be a tagger.
289 - In a fatal error message in load_one_actions_file(), cover both
291 - In pcrs_strerror(), properly report unknown positive error code
293 Previously they were handled like 0 (no error).
294 - In compile_dynamic_pcrs_job_list(), also log the actual error code as
295 pcrs_strerror() doesn't handle all errors reported by pcre
296 - Don't bother trying to continue chatting if the client didn't ask for it.
297 Reduces log noise a bit.
298 - Make two fatal error message in load_one_actions_file() more descriptive
299 - In cgi_send_user_manual(), log when rejecting a file name due to '/' or '..'
300 - In load_file(), log a message if opening a file failed
301 The CGI error message alone isn't too helpful.
302 - In connection_destination_matches(), improve two log messages to
303 help understand why the destinations don't match
304 - Rephrase a log message in serve(). Client request arrival
305 should be differentiated from closed client connections now.
306 - In serve(), log if a client connection isn't reused due to a
307 configuration file change.
308 - Let mark_server_socket_tainted() always mark the server socket tainted,
309 just don't talk about it in cases where it has no effect.
310 It doesn't change Privoxy's behaviour, but makes understanding
314 - Added a --disable-ipv6-support switch for platforms where support
315 is detected but doesn't actually work.
316 - Do not check for the existence of strerror() and memmove() twice
317 - Remove a useless test for setpgrp(2). Privoxy doesn't
318 need it and it can cause problems when cross-compiling
319 - Rename the --disable-acl-files switch to --disable-acl-support
320 Since about 2001, ACL directives are specified in the standard config file.
321 - Update the URL of the 'Removing outdated PCRE version after the
322 next stable release' posting.
323 The old URL stopped working after one of SF's recent layout pessimizations.
326 - Privoxy-Regression-Test:
327 - Added --shuffle-tests option to increase the chances of detection race conditions
328 - Added a --local-test-file option that allows to use Privoxy-Regression-Test without Privoxy
329 - Added tests for missing socks4 and socks4a forwarders
330 - The --privoxy-address option now works with IPv6 addresses
331 containing brackets, too
332 - Perform limited sanity checks for parameters that are supposed
333 to have numerical values.
334 - Added a --sleep-time option to specify a number of seconds to
335 sleep between tests, defaults to 0.
336 - Disable the range-requests tagger for tests that break if it's enabled
337 - Log messages use the ISO 8601 date format %Y-%m-%d.
338 - Fix spelling in two error messages.
339 - In the --help output, include a list of supported tests and their default levels.
341 - Privoxy-Log-Parser:
342 - Perform limited sanity checks for parameters that are supposed
343 to have numerical values.
344 - Implement a --unbreak-lines-only option to try to revert MUA breakage.
345 - Accept and highlight: Added header: Content-Encoding: deflate
346 - Accept and highlight: Compressed content from 29258 to 8630 bytes.
347 - Accept and highlight: Client request arrived in time on socket 21.
348 - Highlight: Didn't receive data in time: a.fsdn.com:443
349 - Accept log messages with ISO 8601 time stamps, too
352 - Bump generated Firefox version to 8.0
353 - Only randomize the release date if the new --randomize-release-date option is enabled.
354 Firefox versions after 4 use a fixed date string without meaning.
357 *** Version 3.0.17 Stable ***
359 - Fixed last-chunk-detection for responses where the body was small
360 enough to be read with the headers, causing Privoxy to wait for the
361 end of the content until the server closed the connection or the
362 request timed out. Reported by "Karsten" in #3028326.
363 - Responses with status code 204 weren't properly detected as body-less
364 like RFC2616 mandates. Like the previous bug, this caused Privoxy to
365 wait for the end of the content until the server closed the connection
366 or the request timed out. Fixes #3022042 and #3025553, reported by a
367 user with no visible name. Most likely also fixes a bunch of other
368 AJAX-related problem reports that got closed in the past due to
369 insufficient information and lack of feedback.
370 - Fixed an ACL bug that made it impossible to build a blacklist.
371 Usually the ACL directives are used in a whitelist, which worked
372 as expected, but blacklisting is still useful for public proxies
373 where one only needs to deny known abusers access.
374 - Added LOG_LEVEL_RECEIVED to log the not-yet-parsed data read from the
375 network. This should make debugging various parsing issues a lot easier.
376 - The IPv6 code is enabled by default on Windows versions that support it.
377 Patch submitted by oCameLo in #2942729.
378 - In mingw32 versions, the user.filter file is reachable through the
379 GUI, just like default.filter is. Feature request 3040263.
380 - Added the configure option --enable-large-file-support to set a few
381 defines that are required by platforms like GNU/Linux to support files
382 larger then 2GB. Mainly interesting for users without proper logfile
384 - Logging with "debug 16" no longer stops at the first nul byte which is
385 pretty useless. Non-printable characters are replaced with their hex value
386 so the result can't span multiple lines making parsing them harder then
388 - Privoxy logs when reading an action, filter or trust file.
389 - Fixed incorrect regression test markup which caused a test in
390 3.0.16 to fail while Privoxy itself was working correctly.
391 While Privoxy accepts hide-referer, too, the action name is actually
392 hide-referrer which is also the name used one the final results page,
393 where the test expected the alias.
395 - CGI interface improvements:
396 - In finish_http_response(), continue to add the 'Connection: close'
397 header if the client connection will not be kept alive.
398 Anonymously pointed out in #2987454.
399 - Apostrophes in block messages no longer cause parse errors
400 when the blocked page is viewed with JavaScript enabled.
401 Reported by dg1727 in #3062296.
402 - Fix a bunch of anchors that used underscores instead of dashes.
403 - Allow to keep the client connection alive after crunching the previous request.
404 Already opened server connections can be kept alive, too.
405 - In cgi_show_url_info(), don't forget to prefix URLs that only contain
406 http:// or https:// in the path. Fixes #2975765 reported by Adam Piggott.
407 - Show the 404 CGI page if cgi_send_user_manual() is called while
408 local user manual delivery is disabled.
410 - Action file improvements:
411 - Enable user.filter by default. Suggested by David White in #3001830.
412 - Block .sitestat.com/. Reported by johnd16 in #3002725.
413 - Block .atemda.com/. Reported by johnd16 in #3002723.
414 - Block js.adlink.net/. Reported by johnd16 in #3002720.
415 - Block .analytics.yahoo.com/. Reported by johnd16 in #3002713.
416 - Block sb.scorecardresearch.com, too. Reported by dg1727 in #2992652.
417 - Fix problems noticed on Yahoo mail and news pages.
418 - Remove the too broad yahoo section, only keeping the
419 fast-redirects exception as discussed on ijbswa-devel@.
420 - Don't block adesklets.sourceforge.net. Reported in #2974204.
421 - Block chartbeat ping tracking. Reported in #2975895.
422 - Tag CSS and image requests with cautious and medium settings, too.
423 - Don't handle view.atdmt.com as image. It's used for click-throughs
424 so users should be able to "go there anyway".
425 Reported by Adam Piggott in #2975927.
426 - Also let the refresh-tags filter remove invalid refresh tags where
427 the 'url=' part is missing. Anonymously reported in #2986382.
428 While at it, update the description to mention the fact that only
429 refresh tags with refresh times above 9 seconds are covered.
430 - javascript needs to be blocked with +handle-as-empty-document to
431 work around Firefox bug 492459. So move .js blockers from
432 +block{Might be a web-bug.} -handle-as-empty-document to
433 +block{Might be a web-bug.} +handle-as-empty-document.
434 - ijbswa-Feature Requests-3006719 - Block 160x578 Banners.
435 - Block another omniture tracking domain.
436 - Added a range-requests tagger.
437 - Added two sections to get Flickr's Ajax interface working with
438 default pre-settings. If you change the configuration to block
439 cookies by default, you'll need additional exceptions.
440 Reported by Mathias Homann in #3101419 and by Patrick on ijbswa-users@.
442 - Documentation improvements:
443 - Explicitly mention how to match all URLs.
444 - Consistently recommend socks5 in the Tor FAQ entry and mention
445 its advantage compared to socks4a. Reported by David in #2960129.
446 - Slightly improve the explanation of why filtering may appear
448 - Grammar fixes for the ACL section.
449 - Fixed a link to the 'intercepting' entry and add another one.
450 - Rename the 'Other' section to 'Mailing Lists' and reword it
451 to make it clear that nobody is forced to use the trackers
452 - Note that 'anonymously' posting on the trackers may not always
454 - Suggest to enable debug 32768 when suspecting parsing problems.
456 - Privoxy-Log-Parser improvements:
457 - Gather statistics for ressources, methods, and HTTP versions
459 - Also gather statistics for blocked and redirected requests.
460 - Provide the percentage of keep-alive offers the client accepted.
461 - Add a --url-statistics-threshold option.
462 - Add a --host-statistics-threshold option to also gather
463 statistics about how many request where made per host.
464 - Fix a bug in handle_loglevel_header() where a 'scan: ' got lost.
465 - Add a --shorten-thread-ids option to replace the thread id with
467 - Accept and ignore: Looks like we got the last chunk together
468 with the server headers. We better stop reading.
469 - Accept and ignore: Continue hack in da house.
470 - Accept and higlight: Rejecting connection from 10.0.0.2.
471 Maximum number of connections reached.
472 - Accept and highlight: Loading actions file: /usr/local/etc/privoxy/default.action
473 - Accept and highlight: Loading filter file: /usr/local/etc/privoxy/default.filter
474 - Accept and highlight: Killed all-caps Host header line: HOST: bestproxydb.com
475 - Accept and highlight: Reducing expected bytes to 0. Marking
476 the server socket tainted after throwing 4 bytes away.
477 - Accept: Merged multiple header lines to: 'X-FORWARDED-PROTO: http X-HOST: 127.0.0.1'
480 - Remove the next member from the client_state struct. Only the main
481 thread needs access to all client states so give it its own struct.
482 - Garbage-collect request_contains_null_bytes().
483 - Ditch redundant code in unload_configfile().
484 - Ditch LogGetURLUnderCursor() which doesn't seem to be used anywhere.
485 - In write_socket(), remove the write-only variable write_len in
486 an ifdef __OS2__ block. Spotted by cppcheck.
487 - In connect_to(), don't declare the variable 'flags' on OS/2 where
488 it isn't used. Spotted by cppcheck.
489 - Limit the scope of various variables. Spotted by cppcheck.
490 - In add_to_iob(), turn an interestingly looking for loop into a
492 - Code cleanup in preparation for external filters.
493 - In listen_loop(), mention the socket on which we accepted the
494 connection, not just the source IP address.
495 - In write_socket(), also log the socket we're writing to.
496 - In log_error(), assert that escaped characters get logged
497 completely or not at all.
498 - In log_error(), assert that ival and sval have reasonable values.
499 There's no reason not to abort() if they don't.
500 - Remove an incorrect cgi_error_unknown() call in a
501 cannot-happen-situation in send_crunch_response().
502 - Clean up white-space in http_response definition and
503 move the crunch_reason to the beginning.
504 - Turn http_response.reason into an enum and rename it
505 to http_response.crunch_reason.
506 - Silence a 'gcc (Debian 4.3.2-1.1) 4.3.2' warning on i686 GNU/Linux.
507 - Fix white-space in a log message in remove_chunked_transfer_coding().
508 While at it, add a note that the message doesn't seem to
509 be entirely correct and should be improved later on.
511 - GNUmakefile improvements:
512 - Use $(SSH) instead of ssh, so one only needs to specify a username once.
513 - Removed references to the action feedback thingy that hasn't been
515 - Consistently use shell.sourceforge.net instead of shell.sf.net so
516 one doesn't need to check server fingerprints twice.
517 - Removed GNUisms in the webserver and webactions targets so they
518 work with standard tar.
520 *** Version 3.0.16 Stable ***
522 - Added the config file option handle-as-empty-doc-returns-ok to
523 work around Firefox bug #492459, which causes Firefox to hang
524 if JavaScripts are blocked in certain situations. The option is
525 enabled in the default config file.
526 - Added the config file option default-server-timeout to control the
527 assumed default server timeout. Since Privoxy no longer returns
528 an error message for connection resets on reused client connections,
529 assuming larger server timeout values appears to actually work
530 pretty well as long as connections aren't shared.
531 - Added optional support for FreeBSD's accf_http(9). Use the
532 configure option --enable-accept-filter to enable it.
533 - Added fancier Privoxy icons for win32. Contributed by Jeff H.
534 - In daemon mode, fd 0, 1 and 2 are bound to /dev/null.
535 - Resolve localhost using whatever address family the operating
536 system feels like. Previous betas would try to use IPv4 as this
537 is what most users expect, but this didn't work reliably on
539 - In the action lists on CGI pages, actions and their parameters are
540 no longer separated with a space. The action file parser doesn't
541 actually allow this and will throw an invalid syntax error if actions
542 and parameters in the action files are separated. Not adding the
543 spaces means copy and pasting CGI output into the action files works.
544 - The default keep-alive timeout has been reduced to 5 seconds to work
545 around hangs in clients that treat the proxy like any other host and
546 stop allowing any new connections if the "maximum number of
547 connections per host" is reached.
548 - Several webbug URLs that look like they are leading to images are now
549 blocked as image instead of empty documents. Doing the latter causes
550 WebKit-based clients to show a "missing image" icon which may mess up
552 - The no-such-domain template is used for DNS resolution
553 problems with FEATURE_IPV6_SUPPORT enabled. Previously the
554 connect-failed template was used. Reported by 'zebul666'.
555 - Accepts quoted expiration dates even though RFC 2109 10.1.2
556 doesn't seem to allow them. Reported anonymously.
557 - Don't try to forget connections if connection sharing is disabled.
558 This wasn't a real problem but caused an unnecessary log message.
559 - The still undocumented --enable-extended-host-patterns configure
560 option has a better description.
561 - Fixed an error message that would claim a write to the server
562 failed when actually writing to the client failed.
563 - Log the crunch reason before trying to write to the client.
564 The log is easier to read that way.
565 - Several log messages about client connections also mention
567 - handle-as-empty-document no longer depends on the image blocking
569 - Privoxy-Log-Parser is roughly 40% faster in highlighting mode.
570 - uagen, a Firefox User-Agent generator for Privoxy and Mozilla
571 browsers has been imported and is available in the tarball's
573 - The scripts in the tools directory treat unknown parameters
576 *** Version 3.0.15 Beta ***
578 - In case of missing server data, no error message is send to the
579 client if the request arrived on a reused connection. The client
580 is then supposed to silently retry the request without bothering
581 the user. This should significantly reduce the frequency of the
582 "No server or forwarder data received" error message many users
584 - More reliable detection of prematurely closed client sockets
585 with keep-alive enabled.
586 - FEATURE_CONNECTION_KEEP_ALIVE is decoupled from
587 FEATURE_CONNECTION_SHARING and now available on
589 - Improved handling of POST requests on reused connections.
590 Should fix problems with stalled connections after submitting
591 form data with some browser configurations.
592 - Fixed various latency calculation issues.
593 - Allows the client to pass NTLM authentication requests to a
594 forwarding proxy. This was already assumed and hinted to work
595 in 3.0.13 beta but actually didn't. Now it's confirmed to work
596 with IE, Firefox and Chrome.
597 Thanks to Francois Botha and Wan-Teh Chang
598 - Fixed a calculation problem if receiving the server headers
599 takes more than two reads, that could cause Privoxy to terminate
600 the connection prematurely. Reported by Oliver.
601 - Compiles again on platforms such as OpenBSD and systems
602 using earlier glibc version that don't support AI_ADDRCONFIG.
603 Anonymously submitted in #2872591.
604 - A bunch of MS VC project files and Suse and Redhat RPM spec
605 files have been removed as they were no longer maintained for
607 - Overly long action lines are properly rejected with a proper
608 error message. Previously they would be either rejected as
609 invalid or cause a core dump through abort().
610 - Already timed-out connections are no longer temporarily remembered.
611 They weren't reused anyway, but wasted a socket slot.
612 - len refers to the number of bytes actually read which might
613 differ from the ones received. Adjust log messages accordingly.
614 - The optional JavaScript on the CGI page uses encodeURIComponent()
615 instead of escape() which doesn't encode all characters that matter.
616 Anonymously reported in #2832722.
617 - Fix gcc45 warnings in decompress_iob().
618 - Various log message improvements.
619 - Privoxy-Regression-Test supports redirect tests.
620 - Privoxy-Log-Parser can gather some connection statistics.
622 *** Version 3.0.14 Beta ***
624 - The latency is taken into account when evaluating whether or not to
625 reuse a connection. This should significantly reduce the number of
626 connections problems several users reported.
627 - If the server doesn't specify how long the connection stays alive,
628 Privoxy errs on the safe side of caution and assumes it's only a second.
629 - The error pages for connection timeouts or missing server data use a
630 Last-Modified date in the past. Retry attempts are detected and Privoxy
631 removes the If-Modified-Since header to prevent the server from responding
632 with status code 304 in which case the client would reuse the error message.
633 - Setting keep-alive-timeout to 0 disables keep-alive support. Previously
634 Privoxy would claim to allow persistence but not reuse the connection.
635 - Pipelined requests are less likely to be mistaken for the request
636 body of the previous request. Note that Privoxy still has no real
637 pipeline support and will either serialize pipelined requests or
638 drop them in which case the client has to resent them.
639 - Fixed a crash on some Windows versions when header randomization
640 is enabled and the date couldn't be parsed.
641 - Privoxy's keep-alive timeout for the current connection is reduced
642 to the one specified in the client's Keep-Alive header.
643 - For HTTP/1.1 requests, Privoxy implies keep-alive support by not
644 setting any Connection header instead of using 'Connection: keep-alive'.
645 - If the socket isn't reusable, Privoxy doesn't temporarily waste
646 a socket slot to remember the connection.
647 - If keep-alive support is disabled but compiled in, the client's
648 Keep-Alive header is removed.
649 - Fixed a bug on mingw32 where downloading large files failed if
650 keep-alive support was enabled.
651 - Fixed a bug that (at least theoretically) could cause log
652 timestamps to be occasionally off by about a second.
653 - No Proxy-Connection header if added if there already is one.
654 - The configure script respects the $PATH variable when searching
657 *** Version 3.0.13 Beta ***
659 - Added IPv6 support. Thanks to Petr Pisar who not only provided
660 the initial patch but also helped a lot with the integration.
661 - Added client-side keep-alive support.
662 - The connection sharing code is only used if the connection-sharing
664 - The max-client-connections option has been added to restrict
665 the number of client connections below a value enforced by
666 the operating system.
667 - Fixed a regression reintroduced in 3.0.12 that could cause
668 crashes on mingw32 if header date randomization was enabled.
669 - Compressed content with extra fields couldn't be decompressed
670 and would get passed to the client unfiltered. This problem
671 has only be detected through statical analysis with clang as
672 nobody seems to be using extra fields anyway.
673 - If the server resets the Connection after sending only the headers
674 Privoxy forwards what it got to the client. Previously Privoxy
675 would deliver an error message instead.
676 - Error messages in case of connection timeouts use the right
678 - If spawning a child to handle a request fails, the client
679 gets an error message and Privoxy continues to listen for
680 new requests right away.
681 - The error messages in case of server-connection timeouts or
682 prematurely closed server connections are now template-based.
683 - If zlib support isn't compiled in, Privoxy no longer tries to
684 filter compressed content unless explicitly asked to do so.
685 - In case of connections that are denied based on ACL directives,
686 the memory used for the client IP is no longer leaked.
687 - Fixed another small memory leak if the client request times out
688 while waiting for client headers other than the request line.
689 - The client socket is kept open until the server socket has
690 been marked as unused. This should increase the chances that
691 the still-open connection will be reused for the client's next
692 request to the same destination. Note that this only matters
693 if connection-sharing is enabled.
694 - A TODO list has been added to the source tarball to give potential
695 volunteers a better idea of what the current goals are. Donations
696 are still welcome too: http://www.privoxy.org/faq/general.html#DONATE
698 *** Version 3.0.12 ***
700 - The socket-timeout option now also works on platforms whose
701 select() implementation modifies the timeout structure.
702 Previously the timeout was triggered even if the connection
703 didn't stall. Reported by cyberpatrol.
704 - The Connection: keep-alive code properly deals with files
705 larger than 2GB. Previously the connection was closed too
707 - The content length for files above 2GB is logged correctly.
708 - The user-manual directive on the show-status page links to
709 the documentation location specified with the directive,
710 not to the Privoxy website.
711 - When running in daemon mode, Privoxy doesn't log anything
712 to the console unless there are errors before the logfile
714 - The show-status page prints warnings about invalid directives
715 on the same line as the directives themselves.
716 - Fixed several justified (but harmless) compiler warnings,
717 mostly on 64 bit platforms.
718 - The mingw32 version explicitly requests the default charset
719 to prevent display problems with some fonts available on more
720 recent Windows versions. Patch by Burberry.
721 - The mingw32 version uses the Privoxy icon in the alt-tab
722 windows. Patch by Burberry.
723 - The timestamp and the thread id is omitted in the "Fatal error"
724 message box on mingw32.
725 - Fixed two related mingw32-only buffer overflows. Triggering
726 them required control over the configuration file, therefore
727 this isn't seen as a security issue.
728 - In verbose mode, or if the new option --show-skipped-tests
729 is used, Privoxy-Regression-Test logs skipped tests and the
732 *** Version 3.0.11 ***
734 - On most platforms, outgoing connections can be kept alive and
735 reused if the server supports it. Whether or not this improves
736 things depends on the connection.
737 - When dropping privileges, membership in supplementary groups
738 is given up as well. Not doing that can lead to Privoxy running
739 with more rights than necessary and violates the principle of
740 least privilege. Users of the --user option are advised to update.
741 Thanks to Matthias Drochner for reporting the problem,
742 providing the initial patch and testing the final version.
743 - Passing invalid users or groups with the --user option
744 didn't lead to program exit. Regression introduced in 3.0.7.
745 - The match all section has been moved from default.action
746 to a new file called match-all.action. As a result the
747 default.action no longer needs to be touched by the user
748 and can be safely overwritten by updates.
749 - The standard.action file has been removed. Its content
750 is now part of the default.action file.
751 - In some situations the logged content length was slightly too low.
752 - Crunched requests are logged with their own log level.
753 If you used "debug 1" in the past, you'll probably want
754 to additionally enable "debug 1024", otherwise only passed
755 requests will be logged. If you only care about crunched
756 requests, simply replace "debug 1" with "debug 1024".
757 - The crunch reason has been moved to the beginning of the
758 crunch message. For HTTP URLs, the protocol is logged as well.
759 - Log messages are shortened by printing the thread id on its
760 own (as opposed to putting it inside the string "Privoxy()").
761 - The config option socket-timeout has been added to control
762 the time Privoxy waits for data to arrive on a socket.
763 - Support for remote toggling is controlled by the configure
764 option --disable-toggle only. In previous versions it also
765 depended on the action editor and thus configuring with the
766 --disable-editor option would disable remote toggling support
768 - Requests with invalid HTTP versions are rejected.
769 - The template symbol @date@ can be used to include a date(1)-like
770 time string. Initial patch submitted by Endre Szabo.
771 - Responses from shoutcast servers are accepted again.
772 Problem reported and fix suggested by Stefan.
773 - The hide-forwarded-for-headers action has been replaced with
774 the change-x-forwarded-for{} action which can also be used to
775 add X-Forwarded-For headers. The latter functionality already
776 existed in Privoxy versions prior to 3.0.7 but has been removed
777 as it was often used unintentionally (by not using the
778 hide-forwarded-for-headers action).
779 - A "clear log" view option was added to the mingw32 version
780 to clear out all of the lines in the Privoxy log window.
781 Based on a patch submitted by T Ford.
782 - The mingw32 version uses "critical sections" now, which prevents
783 log message corruption under load. As a side effect, the
784 "no thread-safe PRNG" warning could be removed as well.
785 - The mingw32 version's task bar icon is crossed out and
786 the color changed to gray if Privoxy is toggled off.
788 *** Version 3.0.10 ***
790 - Ordinary configuration file changes no longer cause program
791 termination on OS/2 if the name of the logfile hasn't been
792 changed as well. This regression probably crept in with the
793 logging improvements in 3.0.7. Reported by Maynard.
794 - The img-reorder filter is less likely to mess up JavaScript code in
795 img tags. Problem and solution reported by Glenn Washburn in #2014552.
796 - The source tar ball now includes Privoxy-Log-Parser,
797 a syntax-highlighter for Privoxy logs. For fancy screenshots see:
798 http://www.fabiankeil.de/sourcecode/privoxy-log-parser/
799 Documentation is available through perldoc(1).
801 *** Version 3.0.9 Beta ***
803 - Added SOCKS5 support (with address resolution done by
804 the SOCKS5 server). Patch provided by Eric M. Hopper.
805 - The "blocked" CGI pages include a block reason that was
806 provided as argument to the last-applying block action.
807 - If enable-edit-actions is disabled (the default since 3.0.7 beta)
808 the show-status page hides the edit buttons and explains why.
809 Previously the user would get the "this feature has been disabled"
810 message after using the edit button.
811 - Forbidden CONNECT requests are treated like blocks by default.
812 The now-pointless treat-forbidden-connects-like-blocks action
814 - Not enabling limit-connect now allows CONNECT requests to all ports.
815 In previous versions it would only allow CONNECT requests to port 443.
816 Use +limit-connect{443} if you think you need the old default behaviour.
817 - The CGI editor gets turned off after three edit requests with invalid
818 file modification timestamps. This makes life harder for attackers
819 who can leverage browser bugs to send fake Referers and intend to
820 brute-force edit URLs.
821 - Action settings for multiple patterns in the same section are
822 shared in memory. As a result these sections take up less space
823 (and are loaded slightly faster). Problem reported by Franz Schwartau.
824 - Linear white space in HTTP headers will be normalized to single
825 spaces before parsing the header's content, headers split across
826 multiple lines get merged first. This should prevent problems like:
827 * letting the session-cookies-only action slip
828 some Cookies through unmodified,
829 * only suppressing the first line of a header,
830 thus creating an invalid one, and
831 * to incorrectly block headers with valid timestamps
832 that weren't properly recognized.
833 Headers that could trigger these problems are unlikely to appear
834 in "normal" web traffic, but could be intentionally generated to
835 fool some of Privoxy's header parsers.
836 - Host information is gathered outside the main thread so it's less
837 likely to delay other incoming connections if the host is misconfigured.
838 - New config option "hostname" to use a hostname other than
839 the one returned by the operating system. Useful to speed-up responses
840 for CGI requests on misconfigured systems. Requested by Max Khon.
841 - The CGI editor supports the "disable all filters of this type"
842 directives "-client-header-filter", "-server-header-filter",
843 "-client-header-tagger" and "-server-header-tagger".
844 - Fixed false-positives with the link-by-url filter and URLs that
845 contain the pattern "/jump/".
846 - The less-download-windows filter no longer messes
847 "Content-Type: application/x-shockwave-flash" headers up.
848 - In the show-url-info page's "Final results" section active and
849 inactive actions are listed separately. Patch provided by Lee.
850 - The GNUmakefile supports the DESTDIR variable. Patch for
851 the install target submitted by Radoslaw Zielinski.
852 - Embedding the content of configuration files in the show-status
853 page is significantly faster now. For a largish action file (1 MB)
854 a speedup of about 2450 times has been measured. This is mostly
855 interesting if you are using large action files or regularly use
856 Privoxy-Regression-Test while running Privoxy through Valgrind,
857 for stock configuration files it doesn't really matter.
858 - If zlib support is unavailable and there are content
859 filters active but the prevent-compression action is disabled,
860 the show-url-info page includes a warning that compression
861 might prevent filtering.
862 - The show-url-info page provides an OpenSearch Description that
863 allows to access the page through browser search plugins.
864 - Custom client-header filters that rewrite the request line
865 incorrectly no longer cause Privoxy to crash. Reported by din_a4.
866 - The obsolete kill-popups action has been removed as the
867 PCRS-based popup filters can do the same and are slightly
869 - The inspect-jpegs action has been removed.
870 - The send-wafer and send-vanilla-wafer actions have been removed.
871 They weren't particular useful and their behaviour could be emulated
872 with add-header anyway.
873 - Privoxy-Regression-Test has been significantly improved.
874 - Most sections in the default.action file contain tests for
875 Privoxy-Regression-Test to verify that they are working as intended.
876 - Parts of Privoxy have been refactored to increase maintainability.
877 - Building with zlib (if available) is done by default.
879 *** Version 3.0.8 ***
881 - Fixed a small memory leak when listen-address only specifies the port.
882 - The source tar balls now include Privoxy-Regression-Test which
883 (upon other things) can be used to automatically detect some
884 packaging problems. Packagers are welcome to give it a try.
885 - Reverted a change in 3.0.7 that caused path patterns to be checked
886 even if the host pattern match already failed. While this doesn't
887 noticeable affect the performance, it makes it less likely to run
888 out of stack space with overly-complex path patterns the user might
890 - Updated the msn, yahoo and google filters to work as advertised again.
891 - The warning message shown by the show-status CGI page is easier to
892 understand. Previously it wasn't clear that the error message
893 is shown below the invalid directive. (Reported by Lee)
894 - When regenerating Content-Disposition headers the more common
895 spelling is used for the name. Previously it was written without caps.
896 - Less confusing log message if the content type isn't overwritten
897 because force-text-type wasn't used but the old type doesn't look
898 like content that would be filtered normally.
899 - Better log messages if the user tries to execute filters that
901 - Treat the non-standard Request-Range headers like standard range
902 headers and suppress them if content filtering is enabled.
903 - Prevent the log messages for CONNECT requests to unacceptable
904 ports from printing the limit-connect argument as [null] if
905 limit-connect hasn't been explicitly enabled.
906 - Don't disable the mingw32 log window if the logfile directive
907 isn't used. While it was an intentional change in 3.0.7 at least
908 one user perceived it as a regression and the same effect can
909 be achieved by disabling all debug directives.
910 - Fixed two minor problems related to the win32 build process: a css
911 file was not being in the installer and the trustfile comment in the
912 config.txt referenced a nonexisting file
913 - Minor documentation fixes.
915 *** Version 3.0.7 Beta ***
917 - Added zlib support to filter content with gzip and deflate
918 encoding. (Patch provided by Wil Mahan)
919 - Dedicated filters and actions are used for header filtering.
920 "filter-client-headers" and "filter-client-headers" are no longer
921 supported, use server-header-filter{} and client-header-filter{}
923 - Tags can be used to change actions based on HTTP headers.
924 - New server-header filter: less-download-windows.
925 - New client-header taggers: css-requests, image-requests,
926 client-ip-address, http-method, allow-post, complete-url,
927 user-agent and privoxy-control.
928 - New server-header taggers: content-type and privoxy-control.
929 - The forward-override{} action allows to change the forwarding
930 settings through the action files, for example based on client
931 headers like the User-Agent, or the request origin.
932 - Socks errors are no longer handled by the CGI page for
933 DNS resolution failures.
934 - CGI pages use favicons to signal whether they are error
935 or control pages. This is useful if you rely heavily on
937 - The show-url-info CGI page shows the forwarding settings.
938 - "Crunch!" log messages (used when Privoxy answers requests
939 by itself) now also contain the reason.
940 - Allow to rewrite the request destination behind the client's back.
941 - Fix socks requests on big-endian platforms. Patch provided by Song Weijia.
942 - Fixes possible deadlocks and crashes on OpenBSD.
943 Patch provided by Ralf Horstmann.
944 - The CGI action editor allows to edit actionfiles with previously
945 forbidden characters like dots.
946 - New trust entries are saved with a comment that contains the
947 trusted referring URL (Suggested by Daniel Griscom).
948 - Filter descriptions are HTML encoded automatically.
949 - New config option "split-large-forms" to work
950 around a browser bug that caused IE6 and IE7 to ignore
951 the Submit button on the edit-actions-for-url CGI page.
952 - New config option "allow-cgi-request-crunching" to allow
953 requests for Privoxy's CGI pages to be blocked, redirected
954 or (un)trusted like ordinary requests.
955 - Empty filter files no longer interrupt the filtering process
956 prematurely and are correctly listed on the show-status CGI page.
957 - New config option "accept-intercepted-requests" to combine
958 Privoxy with any packet filter to build an intercepting proxy
959 for HTTP/1.1 requests (and for HTTP/1.0 requests with Host header set).
960 - fast-redirects{} catch redirects to https URLs as well.
961 - redirect{s@foo@bar@} can be used to redirect to a rewritten
962 version of the original URL.
963 - Trap unsupported gopher proxy requests.
964 - Fixed a bug in the User Manual delivery on Windows
965 (mingw32 only). Images now show up correctly and HTML
966 pages are no longer padded with garbage data.
967 - Fixed several minor memory leaks, most of them discovered with Valgrind.
968 - Only unlink the pidfile if it's actually used.
969 - Retries after connection problems with forced requests
970 aren't blocked again.
971 - On Unix SIGABRT causes a core dump as expected and is no
972 longer treated as normal shutdown signal.
973 - The "access denied" CGI page is more descriptive and
974 allows retries to circumvent the referrer check.
975 - Updated PCRS to handle unexpected PCRE errors properly.
976 Fixed crashes that could occur if Privoxy was build
977 with external PCRE versions newer than Privoxy's internal
978 one. (Reported by Chung-chieh Shan)
979 - Fixed crashes with null bytes in PCRS replacement strings
980 (Patch provided by Felix Gröbert).
981 - Fixed crashes with header time randomization on mingw32.
982 - The CGI style sheet is no longer delivered if the referring
983 page isn't a Privoxy CGI page. This prevents a JavaScript-based
984 Privoxy detection "attack". Note that detecting Privoxy is
985 still possible through other ways and Privoxy was never intended
986 to be invisible anyway.
987 - Added support for AmigaOS 4, fixed build for AmigaOS 3.x.
988 - The show-url-info CGI page displays a warning if Privoxy
989 is currently toggled off.
990 - The show-status CGI page suppresses the edit button
991 for action files if Privoxy has no write access.
992 - Most CGI error pages react properly to HEAD requests.
993 - Requests with RFC 3253 HTTP methods (used by Subversion)
994 are accepted. (Patch provided by Petr Kadlec)
995 - New config option "templdir" to change the location
996 of the CGI templates to make sure customized templates
998 - Better handling of "HTTP/1.1 100 Continue" responses.
999 - The background of the PNG pattern is transparent.
1000 - Fixed XML syntax errors caused by banners-by-size and banners-by-url.
1001 - Fixed crashes and possible action file corruptions
1002 when lines containing hashes are written through the CGI editor.
1003 - Supports dynamic filters which can contain variables.
1004 - Supports tags to change the actions based on client or server headers.
1005 - Incorrect actions are logged before program termination.
1006 - The "actionsfile" syntax in the configuration file is consistent
1007 with the rest of the configuration options and requires the
1008 whole file name. This is an incompatible change, if you use
1009 an old configuration file you might have to append ".action"
1010 to your "actionsfile" directives.
1011 - With the configuration file option "enforce-blocks" the
1012 "go there anyway" mechanism can be disabled without recompiling
1014 - More precise error messages in case of incorrect acl syntax.
1015 - Logs a warning if filtering is enabled but impossible due
1016 to lack of zlib support or use of the prevent-compression action.
1017 - Less noisy handling of Cookie:" and "Connection:" headers.
1018 - Improved error messages in case of connection problems.
1019 - Fix a command-line-parsing bug that was introduced before 3.0.5
1020 beta and caused Privoxy to treat the last argument as configuration
1021 file if no configuration file was specified.
1022 - Treat unknown command line options as fatal errors instead
1023 of silently ignoring them.
1024 - Use string functions with length checks more often.
1025 - Don't log CONNECT requests twice.
1026 - Allow to log the source address for ACL-related connection drops.
1027 - Don't ignore applying filters if the server didn't
1028 specify a Content-Type. Bug reported by Amuro Namie.
1029 - Rejected CONNECT requests are logged with log level info
1030 (enabled by default) and the reason for the block.
1031 - New command line option "--pre-chroot-nslookup hostname" to
1032 intialize the resolver library before chroot'ing. On some systems this
1033 reduces the number of files that must be copied into the chroot tree.
1034 (Patch provided by Stephen Gildea)
1035 - Fix a long-standing memory corruption bug that could cause
1036 Privoxy to overwrite a single byte in memory it didn't explicitly
1037 allocate (but that probably was allocated anyway due to bucket size).
1038 - Send template-based CGI pages as HTTP/1.1 unless the client
1040 - Let the first line in connection established responses
1041 end in \r\n as required by RFC1945. Reported by Bert van Leeuwen.
1042 - If no log file has been specified, disable logging instead of logging
1044 - Don't block stderr when in daemon mode.
1045 - Ignore missing zero-chunks when filtering chunk-encoded content.
1046 Earlier Privoxy versions would buffer and then forward the content
1047 unmodified which caused some browsers to simply show empty pages.
1048 - Fix double free in cgi_edit_actions_list(). Reported by Venustech AD-LAB.
1049 - The code to add X-Forwarded-For headers when the hide-forwarded-for-headers
1050 action isn't being used has been removed.
1051 - Fixed trustfile feature which previously didn't work without FEATURE_TOGGLE.
1053 - Minor code clean-ups, filter and action file updates.
1054 (Some of them reported by Davide Alberani, Markus Elfring,
1055 Stefan Huehner and Adam Piggott)
1057 *** Version 3.0.6 ***
1059 - New content filters: no-ping, google, msn, yahoo and blogspot.
1060 - New header filters: x-httpd-php-to-html, html-to-xml, xml-to-html
1061 and hide-tor-exit-notation.
1062 - The special header "X-Filter: No" now disables header filtering as well.
1063 - Improved the filters img-reorder, js-annoyances, webbugs,
1064 banners-by-size, banners-by-link and ie-exploits to make them
1065 less likely to break anything.
1066 - Removed outdated URL patterns in default.action and added new ones.
1067 - Added redirection from http://p.p/user-manual to http://p.p/user-manual/
1068 - Changed webinterface default values for hide-user-agent, hide-referrer
1069 and set-image-blocker.
1071 *** Version 3.0.5 Beta ***
1073 - Windows version can be installed/started as a service.
1074 - Windows icon stays blue when Privoxy is idle, green when busy.
1075 - Integrated Fabian Keil's extensive patch. See:
1076 http://www.fabiankeil.de/sourcecode/privoxy/. Includes the
1077 following new or significantly improved actions (among many
1078 other improvements):
1080 content-type-overwrite{}
1081 crunch-client-header{string}
1082 crunch-if-none-match
1083 crunch-server-header{string}
1084 fast-redirects{check-decoded-url}
1085 filter-client-headers
1086 filter-server-headers
1088 handle-as-empty-document
1089 hide-accept-language{}
1090 hide-content-disposition{}
1091 hide-if-modified-since
1092 hide-referrer{conditional-block}
1093 overwrite-last-modified{}
1095 treat-forbidden-connects-like-blocks

1098 copies of Privoxy's error messages after the cause of the problem
1100 - Improved DNS error handling.
1101 - Multiple filter files can now be specified in config.
1102 - Added jpeg filtering to defend against MS jpeg vulnerability MS04-028
1103 with the new inspect-jpegs action.
1104 - Removed the "arbitrary" 1000 filter limit - addresses tracker #911950
1105 - Thanks to Jindrich Makovicka for a race condition fix for the log
1106 file. The race condition remains for non-pthread implementations.

1118 *** Version 3.0.3 ***
1120 - Fixed yet another two memory leaks. Process growth seems stopped now.
1121 - Further tightened security against malicious toggle-off links.
1122 - Excluded text/plain MIME types from filtering. This fixes a
1123 couple of client-crashing, download corruption and
1124 Privoxy performance issues, whose root cause lies in
1125 web servers labelling content of unknown type as text/plain.
1126 - Assorted fixes for POSIX compliance, signal handling, graceful
1127 termination, compiler warnings, OSX support, Win32 systray,
1128 error logging, hostname wildcards, correct detection of NetBSD.
1129 - Workarounds for client (iTunes etc) and server (PHP < 4.2.3) bugs
1130 including the notorious "blank page" problem.

1143 - Refined the default action file through >400 items of user feedback
1145 - Assorted refinements, optimizations and fixes in the js-annoyances,
1146 img-reorder, banners-by-size, banners-by-link, webbugs, refresh-tags,
1147 html-annoyances, content-cookies and fun filters
1148 - Replaced filter "popups" by choice between two modes:
1149 - "unsolicited-popups" tries to catch only the unsolicited ones
1150 - "all-popups" tries to kill them all (as before)
1151 - New filter "tiny-textforms" Help those tiny or hard-wrap textareas.
1152 - New filter "jumping-windows" that prevents windows from resizing
1153 and moving themselves
1154 - New filter "demoronizer" which fixes MS's abuse of std charsets
1155 (common cases anyway).
1156 - Replaced "nimda" with more general "ie-exploits" filter in which
1157 all filters for exploits shall be collected
1158 - Improved cookie logging
1159 - Rewrote make install target. Added uninstall and install-strip
1161 - Fixed a potential (application-level, NOT OS-level!) security
1162 problem involving remote toggling and action file manipulation
1163 by mailicious websites.
1164 - Added ability to chroot (thanks to Sviatoslav Sviridov)
1165 - Added more action aliases for prehistoric action names

1185 *** Version 2.9.16 ***
1187 - Major revamp of default.action to get rid of years of cruft.
1188 - Same for default.filter

1213 - Various other minor fixes.
1215 *** Version 2.9.13 Beta ***
1217 - *NEWS*: The project has been renamed to Privoxy! The new name is
1218 reflected throughout (file locations, etc).
1219 - ijb.action is now default.action. re_filterfile is now
1221 - http://i.j.b/ is now http://p.p/

1250 - Fixes for actions cgi editor, make sure we have right file.
1251 - A --pidfile command line option now, in addition to --help,
1252 --version, --no-daemon, --user and configfile. --no-daemon replaces
1253 the former -d option and _DEBUG define. --user will drop privileges
1254 to the specified user.

1289 - Many other minor bugfixes
1290 - Start a ChangeLog :)
1294 *** Version 2.9.3 pre-Alpha Changes ***
1296 - Amiga support (completely untested by me - I don't have an Amiga)
1297 - "tinygif 3" support (redirects blocked images to a specified URL, so
1298 the browser doesn't have to load and cache many copies of the same
1300 - one case where there were both local and global "referrer" variables
1301 (yuck!) clarified by renaming the local one to "refer".
1302 - Fixed some places where close() was used instead of close_socket().
1303 Thanks to Jörg Strohmayer (joergs at users.sourceforge.net) for these.
1304 - Temporary hack to get FORCE_LOAD to work with IE. I just lowercased the
1305 FORCE_LOAD_PREFIX. Needs fixing properly.
1306 - Most URLs hardcoded into Junkbuster were changed to go through a script
1307 e.g. http://ijbswa.sourceforge.net/redirect.php?v=2.9.3&to=faq
1308 The only other URLs left are the GNU GPL:
1309 http://www.fsf.org/copyleft/gpl.html
1311 http://ijbswa.sourceforge.net/
1312 ... and various URLs which will be intercepted by Junkbuster anyway.
1313 TODO: Still need to do something with the URLs in Junkbuster Corp's
1314 copyright/trademark notice on the bottom of the show-proxy-args page.
1315 - PCRE or GNU Regex is now a #define option.
1318 *** Version 2.9.2 pre-Alpha Changes ***
1320 - Andreas applied the latest version of the FORCE patch.
1323 *** Version 2.9.1 pre-Alpha Changes ***
1325 - in parsers.c, fixed two #ifdef FORCE to #ifdef FORCE_LOAD
1326 (BTW: I think FORCE is precise enough, since loading remote
1327 data is the whole purpose of a proxy..)
1328 - Set the FORCE_PREFIX (back) to 'IJB-FORCE-LOAD-'. While 'noijb.'
1329 is more elegant and looks like a hostname in the URL, it doesn't
1330 make clear to the inexperienced user that the proxy is bypassed. It
1331 also has a higher name collision risk.
1332 - Filled in the function header templates for my functions in
1333 parsers.c (again). They obviously got lost in our current
1335 - Cut the credit for the §-referrer-option from the config file,
1336 that Stefan had placed there.
1337 - Improved the re_filterfile
1340 *** Version 2.9.0 pre-Alpha Changes ***
1342 - Now use PCRE, not GNU REGEX. I have not yet had chance to check the
1343 syntax of the block/image/cookie file to ensure that they match what
1344 is expected - however they seem to work.
1345 - Replaced "configure" script with one generated by "autoconf". Also
1346 use a header "config.h" (was ijbconfig.h in my previous release) for
1347 the #defines. "config.h" is now generated with "autoheader" from
1348 "acconfig.h" and "configure.in". (Note that to install you do not
1349 need autoconf or autoheader - just run "./configure".)
1350 To see command-line options, run "./configure --help".
1351 This is my first ever autoconf script, so it has some rough edges
1352 (how PCRE is handled is the roughest).
1353 - Error logging code replaced with new module errlog.c, based on the
1354 one from JunkbusterMT (but with the threading code removed).
1355 - Most of Rodney's 0.21 and 0.21A patches applied. (Marked *). I did not
1356 apply all of these, since I had already independently done conditional
1357 popup file, conditional image file, and integration of popup code.
1358 - ACL, Jar and trust files conditionally compiled.
1359 - New source file headers.
1360 - Various cosmetic changes. (But I have not consistently ordered the
1361 config files - I think that's worthwhile, but it's 1am and I want to
1363 - RCS tags on .h files.
1364 - RCS tags are const char[] rather than const char *. (Saves 4 bytes
1366 - VC++ project files renamed to vc_junkbuster.*.
1367 - show-proxy-args now shows status of all conditionals, not just REGEX
1368 - Various functions moved around. Most notably all the system-specific
1369 sockets code which was spread between jcc.c, bind.c, and connect.c,
1370 has been moved to "jbsockets.c". The non-system-specific code from
1371 connect.c and socks4.c has been movet to "gateway.c". Also, the
1372 config file loader and the global variables it writes to have been
1373 moved to "loadcfg.c". (Maybe this should go into loaders.c?)
1374 And candidate for the "worst filename ever" award is "miscutil.c",
1375 which contains, well, miscellaneous utility functions like zalloc.
1376 (Suggestions for a better name for this file are welcome!)
1377 - Loaders now use a common function to read a line and skip comments,
1378 and this function also stores the proxy_args.
1379 - Added ./junkbuster --help (Not for Win32 GUI)
1380 - Added ./junkbuster --version (Not for Win32 GUI)
1381 - Win32 resources are now all marked as "U.S. English", rather than
1382 being a mix of "U.S. English", "U.K. English" and "Irish English".
1383 - Version number changes to 2.9.0
