4 *** Version 3.0.18 Stable ***
7 - Fix a logic bug that could cause Privoxy to reuse a tainted
9 It could happen for server sockets that got tainted by a
10 server-header-tagger-induced block, in which case Privoxy
11 doesn't necessarily read the whole server response.
12 If keep-alive was enabled and the request following the
13 blocked one was to the same host and using the same
14 forwarding settings, Privoxy would send it on the tainted
16 While the server would simply treat it as a pipelined request,
17 Privoxy would later on fail to properly parse the server's
18 response as it would try to parse the unread data from the
19 first response as server headers for the second one.
20 Regression introduced in 3.0.17.
21 - When implying keep-alive in client_connection(), remember that the client didn't
22 Fixes a regression introduced in 3.0.13 that would cause
23 Privoxy to wait for additional client requests after
24 receiving a HTTP/1.1 request with "Connection: close" set
25 and connection sharing enabled.
26 With clients like curl which terminates the client connection
27 after detecting that the whole body has been received it doesn't
28 really matter, but with clients like FreeBSD's fetch the client
29 connection would be kept open until it timed out.
31 - Fix a subtle race condition between prepare_csp_for_next_request() and sweep()
32 A thread preparing itself for the next client request
33 could briefly appear to be inactive.
34 If all other threads were already using more recent files,
35 the thread could get its files swept away under its feet.
36 I've only seen it while stress testing in valgrind while
37 touching action files in a loop. It's unlikely to have
38 caused any actual problems in the real world.
40 - General improvements:
41 - Privoxy can (re)compress buffered content before delivering
42 it to the client. Disabled by default as most users wouldn't
44 - The +fast-redirects{check-decoded-url} action checks URL
46 If there are other parameters behind the redirect URL,
47 this makes it unnecessary to cut them of by additionally
48 using a +redirect{} pcrs command.
49 Initial patch submitted by Jamie Zawinski in #3429848.
50 - Properly deal with FEATURE_TOGGLE being disabled
51 - Adjust url_code_map[] so spaces are replaced with %20 instead of '+'
52 While '+' can be used by client's submitting form data, this is not
53 actually what Privoxy is using the lookups for. This is more of a
54 cosmetic issue and doesn't fix any actual problems I'm aware of.
55 - When compiled without FEATURE_FAST_REDIRECTS, do not silently
56 ignore +fast-redirect{} directives
57 - Added a workaround for GNU libc's strptime() reporting negative
58 year values when the parsed year is only specified with two digits.
59 On affected systems cookies with such a date would not be turned
60 into session cookies by the +session-cookies-only action.
61 Reported by Vaeinoe in #3403560
62 - When loading action sections, verify that the referenced filters exist
63 Currently missing filters only result in an error message,
64 but eventually the severity will be upgraded to fatal.
65 - Allow to bind to multiple separate addresses.
66 Patch set submitted by Petr Pisar in #3354485.
67 - Set socket_error to errno if connecting fails in rfc2553_connect_to()
68 Previously rejected direct connections could be incorrectly reported as DNS issues.
69 - Fixed bind failures with certain GNU libc versions if no non-loopback
70 IP address has been configured on the system. This is mainly an issue
71 if the system is using DHCP and Privoxy is started before the network
72 is completely configured.
73 Reported by Raphael Marichez in #3349356.
74 Additional insight from Petr Pisar.
75 - Disable filters if SDCH compression is used unless filtering is forced.
76 If SDCH was combined with a supported compression algorithm,
77 we'd previously try to decompress it, when successful apply
78 the enabled filters and ditch the Content-Encoding header
79 even though the SDCH compression wasn't removed.
80 Reported by zebul666 in #3225863.
81 - Privoxy log messages now use the ISO 8601 date format %Y-%m-%d.
82 It's only slightly longer than the old format, but contains
83 the full date including the year and allows sorting by date
84 (when grepping in multiple log files) without hassle.
85 - Make a copy of the --user value and only mess with that when splitting user and group.
86 On some operating systems modifying the value directly
87 is reflected in the output of ps and friends and can
89 Reported by zepard in #3292710.
90 - If forwarded-connect-retries is set, only retry if the we are actually
91 forwarding the request. Previously direct connections would be retried
93 - Fixed a small memory leak when retrying connection
94 - Remove an incorrect assertion in compile_dynamic_pcrs_job_list()
95 It could be triggered by a pcrs job with an invalid pcre
96 pattern (for example one that contains a lone quantifier).
98 - Action file improvements:
100 - Moved the site-specific block pattern section below the one for the
101 generic patterns so for requests that are matched in both, the block
102 reason for the domain is shown which is usually more useful than showing
103 the one for the generic pattern.
104 - Add a (disabled) section to block various Facebook tracking URLs
105 Reported by Dan Stahlke in #3421764.
106 - Add a (disabled) section to rewrite and redirect click-tracking URLs used on news.google.com
107 Reported by Dan Stahlke in #3421755.
108 - Unblock linuxcounter.net/
109 Reported by Dan Stahlke in #3422612.
110 - Block 'www91.intel.com/' which is used by Omniture.
111 Reported by Adam Piggott in #3167370.
112 - Disable the handle-as-empty-doc-returns-ok option and mark it as deprecated.
113 Reminded by tceverling in #2790091.
114 - Add ".ivwbox.de/" to the "Cross-site user tracking" section.
115 Reported by Nettozahler in #3172525.
116 - Unblock and fast-redirect ".awin1.com/.*=http://"
117 Reported by Adam Piggott in #3170921.
118 - Block "b.collective-media.net/".
119 - Widen the Debian popcon exception to "qa.debian.org/popcon".
120 Seen in Debian's 05_default_action.dpatch by Roland Rosenfeld.
121 - Block ".gemius.pl/" which only seems to be used for user tracking.
122 Reported by johnd16 in #3002731. Additional input from Lee and movax.
123 - Disable banners-by-size filters for '.thinkgeek.com/'
124 The filter only seems to catch pictures of the inventory.
125 - Block requests for 'go.idmnet.bbelements.com/please/showit/'
126 Reported by kacperdominik in #3372959.
127 - Unblock adainitiative.org/
128 - Add a fast-redirects exception for '.googleusercontent.com/.*=cache'
129 - Add a fast-redirects exception for webcache.googleusercontent.com/
130 - Remove -prevent-compression from the fragile alias
131 It's no longer used anywhere by default and isn't
132 known to break stuff anyway.
133 - Unblock http://adassier.wordpress.com/ and http://adassier.files.wordpress.com/
135 - Filter file improvements:
136 - Let the yahoo filter hide '.ads'
137 - Let the msn filter hide overlay ads for Facebook 'likes' in search results.
138 - Let the msn filter hide elements with the id 's_notf_div'.
139 They only seem to be used to advertise site 'enhancements'.
140 - Let the js-events filter additionally disarm setInterval()
141 Suggested by dg1727 in #3423775.
143 - Documentation improvements:
144 - Clarify the effect of compiling Privoxy with zlib support
145 Suggested by dg1727 in #3423782.
146 - Point out that the SourceForge messaging system works
147 like a blackhole and should thus not be used
148 - Mention some of the problems one can experience when not
149 explicitly configuring an IP addresses as listen address.
150 - Explicitly mention that hostnames can be used instead of
151 IP addresses for the listen-address, that only the first
152 address returned will be used and what happens if the
154 Requested by Calestyo in #3302213.
156 - Log message improvements:
157 - If only the server connection is kept alive, do not pretent to wait for a new client request.
158 - Remove a superfluos log message in forget_connection()
159 - In chat(), properly report missing server responses as such instead of calling them empty
160 - In forwarded_connect(), fix a log message nobody should ever see
161 - Fix a log message in socks5_connect(), a failed write operation was logged as failed read operation
162 - Let load_one_actions_file() properly complain about a missing '{' at the beginning of the file
163 Simply stating that a line is invalid isn't particularly helpful.
164 - Do not claim to listen on a socket until we actually do.
165 Patch submitted by Petr Pisar #3354485
166 - Prevent a duplicated LOG_LEVEL_CLF message when sending out the "no-server-data" response
167 - Also log the client socket when dropping a connection.
168 - Include the destination host in the
169 'Request ... marked for blocking. limit-connect{...} doesn't allow CONNECT ...' message
170 Patch submitted by Saperski in #3296250.
171 - Prevent a duplicated log message if none of the resolved IP
172 addresses were reachable
173 - In connect_to(), do not pretend to retry if forwarded-connect-retries is zero or unset.
174 - When a specified user or group can't be found, put the name in single-quotes when logging it.
175 - In rfc2553_connect_to(), explain getnameinfo() errors differently.
176 - Remove a useless log message in chat()
177 - When retrying to connect, also log the maximum number of connection attempts
178 - Rephrase a log message in compile_dynamic_pcrs_job_list()
179 Divide the error code and its meaning with a colon.
180 Call the pcrs job dynamic and not the filter. Filters may
181 contain dynamic and non-dynamic pcrs jobs at the same time.
182 Only mention the name of the filter or tagger, but don't
183 claim it's a filter when it could be a tagger.
184 - In a fatal error message in load_one_actions_file(), cover both URL and TAG patterns
185 - In pcrs_strerror(), properly report unknown positive error code values as unknown.
186 Previously they were handled like 0 (no error).
187 - In compile_dynamic_pcrs_job_list(), also log the actual error code as
188 pcrs_strerror() doesn't handle all errors reported by pcre
189 - Don't bother trying to continue chatting if the client didn't ask for it.
190 Reduces log noise a bit.
191 - Make two fatal error message in load_one_actions_file() more descriptive
192 - In cgi_send_user_manual(), log when rejecting a file name due to '/' or '..'
193 - In load_file(), log a message if opening a file failed
194 The CGI error message alone isn't too helpful.
195 - In connection_destination_matches(), improve two log messages to
196 help understand why the destinations don't match
197 - Rephrase a log message in serve(). Client request arrival
198 should be differentiated from closed client connections now.
199 - In serve(), log if a client connection isn't reused due to a
200 configuration file change.
201 - Let mark_server_socket_tainted() always mark the server socket tainted,
202 just don't talk about it in cases where it has no effect.
203 It doesn't change Privoxy's behaviour, but makes understanding
207 - Miscellaneous Privoxy improvements:
208 - In get_last_url(), do not bother trying to decode URLs that do
209 not contain at least one '%' sign. It reduces the log noise and
210 a number of unnecessary memory allocations.
211 - If the --user argument user[.group] contains a dot,
212 always bail out if no group has been specified.
213 Previously the intended, but undocumented (and apparently
214 untested), behaviour was to try interpreting the whole
215 argument as user name, but the detection was flawed and
216 checked for '0' isntead of '\0', thus merely preventing
217 group names beginning with a zero.
218 - Simplify the signal setup in main()
219 - Streamline socks5_connect() slightly
220 - In case of SOCKS5 failures, dump the socks response
221 - In socks5_connect(), require a complete socks response from the server
222 Previously we didn't care how much data the server response
223 contained as long as the first two bytes contained the expected
225 While at it, shrink the buffer size so we can't read more
226 than a whole socks response. This is required to support
227 Tor's optimistic data extension.
228 - In chat(), do not bother to generate a client request in case of direct CONNECT requests
229 - Reduce server_last_modified()'s stack size
230 - Shorten get_http_time() by using strftime()
231 - Constify the known_http_methods pointers in unknown_method()
232 - Constify the time_formats pointers in parse_header_time()
233 - Constify the formerly_valid_actions pointers in action_used_to_be_valid()
234 - In html_code_map[], use a numeric character reference instead of '
235 which wasn't standardized before XHTML 1.0
236 - Introduce a MAN_PAGE variable that defaults to privoxy.1.
237 The Debian package uses section 8 for the man page and this should simplify the patch.
238 - Deduplicate the INADDR_NONE definition for Solaris by moving it to jbsockets.h
239 - In block_url(), ditch the obsolete workaround for ancient Netscape versions
240 that supposedly couldn't properly deal with status code 403.
241 - Remove a useless NULL pointer check in load_trustfile()
242 - Remove two useless NULL pointer checks in load_one_re_filterfile().
243 - Change url_code_map[] from an array of pointers to an array of arrays
244 It removes an unnecessary layer of indirection and on
245 64bit system reduces the size of the binary a bit.
247 Fixes taken from Debian's 29_typos.dpatch by Roland Rosenfeld.
248 - Add a dok-tidy GNUMakefile target to clean up the messy HTML
249 generated by the other dok targets.
250 - GNUisms in the GNUMakefile have been removed.
251 - Change the HTTP version in static responses to 1.1
252 - Synced config.sub and config.guess with upstream
253 2011-11-11/386c7218162c145f5f9e1ff7f558a3fbb66c37c5.
254 - Add a dedicated function to parse the values of toggles
255 Reduces duplicated code in load_config() and provides
256 better error handling. Invalid or missing toggle values
257 are now a fatal error instead of being silently ignored.
258 - Terminate HTML lines in static error messages with \n instead of \r\n.
259 - Simplify cgi_error_unknown() a bit.
260 - In LogPutString(), don't bother looking at pszText when not actually logging anything
261 - Change ssplit()'s fourth parameter from int to size_t.
262 Fixes a clang complaint.
263 - Add a warning that the statistics currently can't be trusted.
264 Mention Privoxy-Log-Parser's --statistics option as
265 an alternative for the time being.
266 - In rfc2553_connect_to(), start setting cgi->error_message on error
267 - Change the expected status code returned for http://p.p/die depending
268 on whether or not FEATURE_GRACEFUL_TERMINATION is available.
269 - In cgi_die(), mark the client connection for closing.
270 If the client will fetch the style sheet through another connection
271 it gets the main thread out of the accept() state and should thus
272 trigger the actual shutdown.
273 - Add a proper CGI message for cgi_die().
274 - Fix an invalid free when compiled with FEATURE_GRACEFUL_TERMINATION
275 and shut down through http://config.privoxy.org/die
276 - Don't enforce a logical line length limit in read_config_line()
277 - Slightly refactor server_last_modified() to remove useless gmtime*() calls
278 - In get_content_type(), also recognize '.jpeg' as JPEG extension
279 - Add '.png' to the list of recognized file extenstions in get_content_type()
280 - In block_url(), consistently use the block reason "Request blocked by Privoxy"
281 In two places the reason was "Request for blocked URL" which
282 hides the fact that the request got blocked by Privoxy and
283 isn't necessarly correct as the block may be due to tags.
284 - In get_actions(), fix the "temporary" backwards compatibility hack
285 to accept block actions without reason.
286 It also covered other actions that should be rejected as invalid.
287 Reported by Billy Crook.
288 - In listen_loop(), reload the configuration files after accepting
289 a new connection instead of before.
290 Previously the first connection that arrived after a configuration
291 change would still be handled with the old configuration.
292 - In chat()'s receive-data loop, skip a client socket check if
293 the socket will be written to right away anyway. This can
294 increase the transfer speed for unfiltered content on fast
296 - The socket timeout is used for SOCKS negotiation as well.
297 - Don't keep the client connection alive if any configuration file
298 changed since the time the connection came in.
299 This is closer to Privoxy's behaviour before keep-alive support
300 for client connection has been added and also less confusing in
302 - Treat all Content-Type header values containing the pattern
303 'script' as a sign of text. Reported by pribog in #3134970.
307 - Added a --disable-ipv6-support switch for platforms where support
308 is detected but doesn't actually work.
309 - Do not check for the existence of strerror() and memmove() twice
310 - Remove a useless test for setpgrp(2). Privoxy doesn't
311 need it and it can cause problems when cross-compiling
312 - Rename the --disable-acl-files switch to --disable-acl-support
313 Since about 2001, ACL directives are specified in the standard config file.
314 - Update the URL of the 'Removing outdated PCRE version after the
315 next stable release' posting.
316 The old URL stopped working after one of SF's recent layout pessimizations.
320 - Privoxy-Regression-Test:
321 - Added --shuffle-tests option to increase the chances of detection race conditions
322 - Added a --local-test-file option that allows to use Privoxy-Regression-Test without Privoxy
323 - Added tests for missing socks4 and socks4a forwarders
324 - The --privoxy-address option now works with IPv6 addresses
325 containing brackets, too
326 - Perform limited sanity checks for parameters that are supposed
327 to have numerical values.
328 - Added a --sleep-time option to specify a number of seconds to
329 sleep between tests, defaults to 0.
330 - Disable the range-requests tagger for tests that break if it's enabled
331 - Log messages use the ISO 8601 date format %Y-%m-%d.
332 - Fix spelling in two error messages.
333 - In the --help output, include a list of supported tests and their default levels.
336 - Privoxy-Log-Parser:
337 - Perform limited sanity checks for parameters that are supposed
338 to have numerical values.
339 - Implement a --unbreak-lines-only option to try to revert MUA breakage.
340 - Accept and highlight: Added header: Content-Encoding: deflate
341 - Accept and highlight: Compressed content from 29258 to 8630 bytes.
342 - Accept and highlight: Client request arrived in time on socket 21.
343 - Highlight: Didn't receive data in time: a.fsdn.com:443
344 - Accept log messages with ISO 8601 time stamps, too
348 - Bump generated Firefox version to 9.0
349 - Only randomize the release date if the new --randomize-release-date option is enabled.
350 Firefox versions after 4 use a fixed date string without meaning.
353 *** Version 3.0.17 Stable ***
355 - Fixed last-chunk-detection for responses where the body was small
356 enough to be read with the headers, causing Privoxy to wait for the
357 end of the content until the server closed the connection or the
358 request timed out. Reported by "Karsten" in #3028326.
359 - Responses with status code 204 weren't properly detected as body-less
360 like RFC2616 mandates. Like the previous bug, this caused Privoxy to
361 wait for the end of the content until the server closed the connection
362 or the request timed out. Fixes #3022042 and #3025553, reported by a
363 user with no visible name. Most likely also fixes a bunch of other
364 AJAX-related problem reports that got closed in the past due to
365 insufficient information and lack of feedback.
366 - Fixed an ACL bug that made it impossible to build a blacklist.
367 Usually the ACL directives are used in a whitelist, which worked
368 as expected, but blacklisting is still useful for public proxies
369 where one only needs to deny known abusers access.
370 - Added LOG_LEVEL_RECEIVED to log the not-yet-parsed data read from the
371 network. This should make debugging various parsing issues a lot easier.
372 - The IPv6 code is enabled by default on Windows versions that support it.
373 Patch submitted by oCameLo in #2942729.
374 - In mingw32 versions, the user.filter file is reachable through the
375 GUI, just like default.filter is. Feature request 3040263.
376 - Added the configure option --enable-large-file-support to set a few
377 defines that are required by platforms like GNU/Linux to support files
378 larger then 2GB. Mainly interesting for users without proper logfile
380 - Logging with "debug 16" no longer stops at the first nul byte which is
381 pretty useless. Non-printable characters are replaced with their hex value
382 so the result can't span multiple lines making parsing them harder then
384 - Privoxy logs when reading an action, filter or trust file.
385 - Fixed incorrect regression test markup which caused a test in
386 3.0.16 to fail while Privoxy itself was working correctly.
387 While Privoxy accepts hide-referer, too, the action name is actually
388 hide-referrer which is also the name used one the final results page,
389 where the test expected the alias.
391 - CGI interface improvements:
392 - In finish_http_response(), continue to add the 'Connection: close'
393 header if the client connection will not be kept alive.
394 Anonymously pointed out in #2987454.
395 - Apostrophes in block messages no longer cause parse errors
396 when the blocked page is viewed with JavaScript enabled.
397 Reported by dg1727 in #3062296.
398 - Fix a bunch of anchors that used underscores instead of dashes.
399 - Allow to keep the client connection alive after crunching the previous request.
400 Already opened server connections can be kept alive, too.
401 - In cgi_show_url_info(), don't forget to prefix URLs that only contain
402 http:// or https:// in the path. Fixes #2975765 reported by Adam Piggott.
403 - Show the 404 CGI page if cgi_send_user_manual() is called while
404 local user manual delivery is disabled.
406 - Action file improvements:
407 - Enable user.filter by default. Suggested by David White in #3001830.
408 - Block .sitestat.com/. Reported by johnd16 in #3002725.
409 - Block .atemda.com/. Reported by johnd16 in #3002723.
410 - Block js.adlink.net/. Reported by johnd16 in #3002720.
411 - Block .analytics.yahoo.com/. Reported by johnd16 in #3002713.
412 - Block sb.scorecardresearch.com, too. Reported by dg1727 in #2992652.
413 - Fix problems noticed on Yahoo mail and news pages.
414 - Remove the too broad yahoo section, only keeping the
415 fast-redirects exception as discussed on ijbswa-devel@.
416 - Don't block adesklets.sourceforge.net. Reported in #2974204.
417 - Block chartbeat ping tracking. Reported in #2975895.
418 - Tag CSS and image requests with cautious and medium settings, too.
419 - Don't handle view.atdmt.com as image. It's used for click-throughs
420 so users should be able to "go there anyway".
421 Reported by Adam Piggott in #2975927.
422 - Also let the refresh-tags filter remove invalid refresh tags where
423 the 'url=' part is missing. Anonymously reported in #2986382.
424 While at it, update the description to mention the fact that only
425 refresh tags with refresh times above 9 seconds are covered.
426 - javascript needs to be blocked with +handle-as-empty-document to
427 work around Firefox bug 492459. So move .js blockers from
428 +block{Might be a web-bug.} -handle-as-empty-document to
429 +block{Might be a web-bug.} +handle-as-empty-document.
430 - ijbswa-Feature Requests-3006719 - Block 160x578 Banners.
431 - Block another omniture tracking domain.
432 - Added a range-requests tagger.
433 - Added two sections to get Flickr's Ajax interface working with
434 default pre-settings. If you change the configuration to block
435 cookies by default, you'll need additional exceptions.
436 Reported by Mathias Homann in #3101419 and by Patrick on ijbswa-users@.
438 - Documentation improvements:
439 - Explicitly mention how to match all URLs.
440 - Consistently recommend socks5 in the Tor FAQ entry and mention
441 its advantage compared to socks4a. Reported by David in #2960129.
442 - Slightly improve the explanation of why filtering may appear
444 - Grammar fixes for the ACL section.
445 - Fixed a link to the 'intercepting' entry and add another one.
446 - Rename the 'Other' section to 'Mailing Lists' and reword it
447 to make it clear that nobody is forced to use the trackers
448 - Note that 'anonymously' posting on the trackers may not always
450 - Suggest to enable debug 32768 when suspecting parsing problems.
452 - Privoxy-Log-Parser improvements:
453 - Gather statistics for ressources, methods, and HTTP versions
455 - Also gather statistics for blocked and redirected requests.
456 - Provide the percentage of keep-alive offers the client accepted.
457 - Add a --url-statistics-threshold option.
458 - Add a --host-statistics-threshold option to also gather
459 statistics about how many request where made per host.
460 - Fix a bug in handle_loglevel_header() where a 'scan: ' got lost.
461 - Add a --shorten-thread-ids option to replace the thread id with
463 - Accept and ignore: Looks like we got the last chunk together
464 with the server headers. We better stop reading.
465 - Accept and ignore: Continue hack in da house.
466 - Accept and higlight: Rejecting connection from 10.0.0.2.
467 Maximum number of connections reached.
468 - Accept and highlight: Loading actions file: /usr/local/etc/privoxy/default.action

470 - Accept and highlight: Killed all-caps Host header line: HOST: bestproxydb.com
471 - Accept and highlight: Reducing expected bytes to 0. Marking
472 the server socket tainted after throwing 4 bytes away.
473 - Accept: Merged multiple header lines to: 'X-FORWARDED-PROTO: http X-HOST: 127.0.0.1'
476 - Remove the next member from the client_state struct. Only the main
477 thread needs access to all client states so give it its own struct.
478 - Garbage-collect request_contains_null_bytes().
479 - Ditch redundant code in unload_configfile().
480 - Ditch LogGetURLUnderCursor() which doesn't seem to be used anywhere.
481 - In write_socket(), remove the write-only variable write_len in
482 an ifdef __OS2__ block. Spotted by cppcheck.
483 - In connect_to(), don't declare the variable 'flags' on OS/2 where
484 it isn't used. Spotted by cppcheck.
485 - Limit the scope of various variables. Spotted by cppcheck.
486 - In add_to_iob(), turn an interestingly looking for loop into a
488 - Code cleanup in preparation for external filters.
489 - In listen_loop(), mention the socket on which we accepted the
490 connection, not just the source IP address.
491 - In write_socket(), also log the socket we're writing to.
492 - In log_error(), assert that escaped characters get logged
493 completely or not at all.
494 - In log_error(), assert that ival and sval have reasonable values.
495 There's no reason not to abort() if they don't.
496 - Remove an incorrect cgi_error_unknown() call in a
497 cannot-happen-situation in send_crunch_response().
498 - Clean up white-space in http_response definition and
499 move the crunch_reason to the beginning.
500 - Turn http_response.reason into an enum and rename it
501 to http_response.crunch_reason.
502 - Silence a 'gcc (Debian 4.3.2-1.1) 4.3.2' warning on i686 GNU/Linux.
503 - Fix white-space in a log message in remove_chunked_transfer_coding().
504 While at it, add a note that the message doesn't seem to
505 be entirely correct and should be improved later on.
507 - GNUmakefile improvements:
508 - Use $(SSH) instead of ssh, so one only needs to specify a username once.
509 - Removed references to the action feedback thingy that hasn't been
511 - Consistently use shell.sourceforge.net instead of shell.sf.net so
512 one doesn't need to check server fingerprints twice.
513 - Removed GNUisms in the webserver and webactions targets so they
514 work with standard tar.
516 *** Version 3.0.16 Stable ***
518 - Added the config file option handle-as-empty-doc-returns-ok to
519 work around Firefox bug #492459, which causes Firefox to hang
520 if JavaScripts are blocked in certain situations. The option is
521 enabled in the default config file.
522 - Added the config file option default-server-timeout to control the
523 assumed default server timeout. Since Privoxy no longer returns
524 an error message for connection resets on reused client connections,
525 assuming larger server timeout values appears to actually work
526 pretty well as long as connections aren't shared.
527 - Added optional support for FreeBSD's accf_http(9). Use the
528 configure option --enable-accept-filter to enable it.
529 - Added fancier Privoxy icons for win32. Contributed by Jeff H.
530 - In daemon mode, fd 0, 1 and 2 are bound to /dev/null.
531 - Resolve localhost using whatever address family the operating
532 system feels like. Previous betas would try to use IPv4 as this
533 is what most users expect, but this didn't work reliably on
535 - In the action lists on CGI pages, actions and their parameters are
536 no longer separated with a space. The action file parser doesn't
537 actually allow this and will throw an invalid syntax error if actions
538 and parameters in the action files are separated. Not adding the
539 spaces means copy and pasting CGI output into the action files works.
540 - The default keep-alive timeout has been reduced to 5 seconds to work
541 around hangs in clients that treat the proxy like any other host and
542 stop allowing any new connections if the "maximum number of
543 connections per host" is reached.
544 - Several webbug URLs that look like they are leading to images are now
545 blocked as image instead of empty documents. Doing the latter causes
546 WebKit-based clients to show a "missing image" icon which may mess up
548 - The no-such-domain template is used for DNS resolution
549 problems with FEATURE_IPV6_SUPPORT enabled. Previously the
550 connect-failed template was used. Reported by 'zebul666'.
551 - Accepts quoted expiration dates even though RFC 2109 10.1.2
552 doesn't seem to allow them. Reported anonymously.
553 - Don't try to forget connections if connection sharing is disabled.
554 This wasn't a real problem but caused an unnecessary log message.
555 - The still undocumented --enable-extended-host-patterns configure
556 option has a better description.
557 - Fixed an error message that would claim a write to the server
558 failed when actually writing to the client failed.
559 - Log the crunch reason before trying to write to the client.
560 The log is easier to read that way.
561 - Several log messages about client connections also mention
563 - handle-as-empty-document no longer depends on the image blocking
565 - Privoxy-Log-Parser is roughly 40% faster in highlighting mode.
566 - uagen, a Firefox User-Agent generator for Privoxy and Mozilla
567 browsers has been imported and is available in the tarball's
569 - The scripts in the tools directory treat unknown parameters
572 *** Version 3.0.15 Beta ***
574 - In case of missing server data, no error message is send to the
575 client if the request arrived on a reused connection. The client
576 is then supposed to silently retry the request without bothering
577 the user. This should significantly reduce the frequency of the
578 "No server or forwarder data received" error message many users
580 - More reliable detection of prematurely closed client sockets
581 with keep-alive enabled.
582 - FEATURE_CONNECTION_KEEP_ALIVE is decoupled from
583 FEATURE_CONNECTION_SHARING and now available on
585 - Improved handling of POST requests on reused connections.
586 Should fix problems with stalled connections after submitting
587 form data with some browser configurations.
588 - Fixed various latency calculation issues.
589 - Allows the client to pass NTLM authentication requests to a
590 forwarding proxy. This was already assumed and hinted to work
591 in 3.0.13 beta but actually didn't. Now it's confirmed to work
592 with IE, Firefox and Chrome.
593 Thanks to Francois Botha and Wan-Teh Chang
594 - Fixed a calculation problem if receiving the server headers
595 takes more than two reads, that could cause Privoxy to terminate
596 the connection prematurely. Reported by Oliver.
597 - Compiles again on platforms such as OpenBSD and systems
598 using earlier glibc version that don't support AI_ADDRCONFIG.
599 Anonymously submitted in #2872591.
600 - A bunch of MS VC project files and Suse and Redhat RPM spec
601 files have been removed as they were no longer maintained for
603 - Overly long action lines are properly rejected with a proper
604 error message. Previously they would be either rejected as
605 invalid or cause a core dump through abort().
606 - Already timed-out connections are no longer temporarily remembered.
607 They weren't reused anyway, but wasted a socket slot.
608 - len refers to the number of bytes actually read which might
609 differ from the ones received. Adjust log messages accordingly.
610 - The optional JavaScript on the CGI page uses encodeURIComponent()
611 instead of escape() which doesn't encode all characters that matter.
612 Anonymously reported in #2832722.
613 - Fix gcc45 warnings in decompress_iob().
614 - Various log message improvements.
615 - Privoxy-Regression-Test supports redirect tests.
616 - Privoxy-Log-Parser can gather some connection statistics.
618 *** Version 3.0.14 Beta ***
620 - The latency is taken into account when evaluating whether or not to
621 reuse a connection. This should significantly reduce the number of
622 connections problems several users reported.
623 - If the server doesn't specify how long the connection stays alive,
624 Privoxy errs on the safe side of caution and assumes it's only a second.
625 - The error pages for connection timeouts or missing server data use a
626 Last-Modified date in the past. Retry attempts are detected and Privoxy
627 removes the If-Modified-Since header to prevent the server from responding
628 with status code 304 in which case the client would reuse the error message.
629 - Setting keep-alive-timeout to 0 disables keep-alive support. Previously
630 Privoxy would claim to allow persistence but not reuse the connection.
631 - Pipelined requests are less likely to be mistaken for the request
632 body of the previous request. Note that Privoxy still has no real
633 pipeline support and will either serialize pipelined requests or
634 drop them in which case the client has to resent them.
635 - Fixed a crash on some Windows versions when header randomization
636 is enabled and the date couldn't be parsed.
637 - Privoxy's keep-alive timeout for the current connection is reduced
638 to the one specified in the client's Keep-Alive header.
639 - For HTTP/1.1 requests, Privoxy implies keep-alive support by not
640 setting any Connection header instead of using 'Connection: keep-alive'.
641 - If the socket isn't reusable, Privoxy doesn't temporarily waste
642 a socket slot to remember the connection.
643 - If keep-alive support is disabled but compiled in, the client's
644 Keep-Alive header is removed.
645 - Fixed a bug on mingw32 where downloading large files failed if
646 keep-alive support was enabled.
647 - Fixed a bug that (at least theoretically) could cause log
648 timestamps to be occasionally off by about a second.
649 - No Proxy-Connection header if added if there already is one.
650 - The configure script respects the $PATH variable when searching
653 *** Version 3.0.13 Beta ***
655 - Added IPv6 support. Thanks to Petr Pisar who not only provided
656 the initial patch but also helped a lot with the integration.
657 - Added client-side keep-alive support.
658 - The connection sharing code is only used if the connection-sharing
660 - The max-client-connections option has been added to restrict
661 the number of client connections below a value enforced by
662 the operating system.
663 - Fixed a regression reintroduced in 3.0.12 that could cause
664 crashes on mingw32 if header date randomization was enabled.
665 - Compressed content with extra fields couldn't be decompressed
666 and would get passed to the client unfiltered. This problem
667 has only be detected through statical analysis with clang as
668 nobody seems to be using extra fields anyway.
669 - If the server resets the Connection after sending only the headers
670 Privoxy forwards what it got to the client. Previously Privoxy
671 would deliver an error message instead.
672 - Error messages in case of connection timeouts use the right
674 - If spawning a child to handle a request fails, the client
675 gets an error message and Privoxy continues to listen for
676 new requests right away.
677 - The error messages in case of server-connection timeouts or
678 prematurely closed server connections are now template-based.
679 - If zlib support isn't compiled in, Privoxy no longer tries to
680 filter compressed content unless explicitly asked to do so.
681 - In case of connections that are denied based on ACL directives,
682 the memory used for the client IP is no longer leaked.
683 - Fixed another small memory leak if the client request times out
684 while waiting for client headers other than the request line.
685 - The client socket is kept open until the server socket has
686 been marked as unused. This should increase the chances that
687 the still-open connection will be reused for the client's next
688 request to the same destination. Note that this only matters
689 if connection-sharing is enabled.
690 - A TODO list has been added to the source tarball to give potential
691 volunteers a better idea of what the current goals are. Donations
692 are still welcome too: http://www.privoxy.org/faq/general.html#DONATE
694 *** Version 3.0.12 ***
696 - The socket-timeout option now also works on platforms whose
697 select() implementation modifies the timeout structure.
698 Previously the timeout was triggered even if the connection
699 didn't stall. Reported by cyberpatrol.
700 - The Connection: keep-alive code properly deals with files
701 larger than 2GB. Previously the connection was closed too
703 - The content length for files above 2GB is logged correctly.
704 - The user-manual directive on the show-status page links to
705 the documentation location specified with the directive,
706 not to the Privoxy website.
707 - When running in daemon mode, Privoxy doesn't log anything
708 to the console unless there are errors before the logfile
710 - The show-status page prints warnings about invalid directives
711 on the same line as the directives themselves.
712 - Fixed several justified (but harmless) compiler warnings,
713 mostly on 64 bit platforms.
714 - The mingw32 version explicitly requests the default charset
715 to prevent display problems with some fonts available on more
716 recent Windows versions. Patch by Burberry.
717 - The mingw32 version uses the Privoxy icon in the alt-tab
718 windows. Patch by Burberry.
719 - The timestamp and the thread id is omitted in the "Fatal error"
720 message box on mingw32.
721 - Fixed two related mingw32-only buffer overflows. Triggering
722 them required control over the configuration file, therefore
723 this isn't seen as a security issue.
724 - In verbose mode, or if the new option --show-skipped-tests
725 is used, Privoxy-Regression-Test logs skipped tests and the
728 *** Version 3.0.11 ***
730 - On most platforms, outgoing connections can be kept alive and
731 reused if the server supports it. Whether or not this improves
732 things depends on the connection.
733 - When dropping privileges, membership in supplementary groups
734 is given up as well. Not doing that can lead to Privoxy running
735 with more rights than necessary and violates the principle of
736 least privilege. Users of the --user option are advised to update.
737 Thanks to Matthias Drochner for reporting the problem,
738 providing the initial patch and testing the final version.
739 - Passing invalid users or groups with the --user option
740 didn't lead to program exit. Regression introduced in 3.0.7.
741 - The match all section has been moved from default.action
742 to a new file called match-all.action. As a result the
743 default.action no longer needs to be touched by the user
744 and can be safely overwritten by updates.
745 - The standard.action file has been removed. Its content
746 is now part of the default.action file.
747 - In some situations the logged content length was slightly too low.
748 - Crunched requests are logged with their own log level.
749 If you used "debug 1" in the past, you'll probably want
750 to additionally enable "debug 1024", otherwise only passed
751 requests will be logged. If you only care about crunched
752 requests, simply replace "debug 1" with "debug 1024".
753 - The crunch reason has been moved to the beginning of the
754 crunch message. For HTTP URLs, the protocol is logged as well.
755 - Log messages are shortened by printing the thread id on its
756 own (as opposed to putting it inside the string "Privoxy()").
757 - The config option socket-timeout has been added to control
758 the time Privoxy waits for data to arrive on a socket.
759 - Support for remote toggling is controlled by the configure
760 option --disable-toggle only. In previous versions it also
761 depended on the action editor and thus configuring with the
762 --disable-editor option would disable remote toggling support
764 - Requests with invalid HTTP versions are rejected.
765 - The template symbol @date@ can be used to include a date(1)-like
766 time string. Initial patch submitted by Endre Szabo.
767 - Responses from shoutcast servers are accepted again.
768 Problem reported and fix suggested by Stefan.
769 - The hide-forwarded-for-headers action has been replaced with
770 the change-x-forwarded-for{} action which can also be used to
771 add X-Forwarded-For headers. The latter functionality already
772 existed in Privoxy versions prior to 3.0.7 but has been removed
773 as it was often used unintentionally (by not using the
774 hide-forwarded-for-headers action).
775 - A "clear log" view option was added to the mingw32 version
776 to clear out all of the lines in the Privoxy log window.
777 Based on a patch submitted by T Ford.
778 - The mingw32 version uses "critical sections" now, which prevents
779 log message corruption under load. As a side effect, the
780 "no thread-safe PRNG" warning could be removed as well.
781 - The mingw32 version's task bar icon is crossed out and
782 the color changed to gray if Privoxy is toggled off.
784 *** Version 3.0.10 ***
786 - Ordinary configuration file changes no longer cause program
787 termination on OS/2 if the name of the logfile hasn't been
788 changed as well. This regression probably crept in with the
789 logging improvements in 3.0.7. Reported by Maynard.
790 - The img-reorder filter is less likely to mess up JavaScript code in
791 img tags. Problem and solution reported by Glenn Washburn in #2014552.
792 - The source tar ball now includes Privoxy-Log-Parser,
793 a syntax-highlighter for Privoxy logs. For fancy screenshots see:
794 http://www.fabiankeil.de/sourcecode/privoxy-log-parser/
795 Documentation is available through perldoc(1).
797 *** Version 3.0.9 Beta ***
799 - Added SOCKS5 support (with address resolution done by
800 the SOCKS5 server). Patch provided by Eric M. Hopper.
801 - The "blocked" CGI pages include a block reason that was
802 provided as argument to the last-applying block action.
803 - If enable-edit-actions is disabled (the default since 3.0.7 beta)
804 the show-status page hides the edit buttons and explains why.
805 Previously the user would get the "this feature has been disabled"
806 message after using the edit button.
807 - Forbidden CONNECT requests are treated like blocks by default.
808 The now-pointless treat-forbidden-connects-like-blocks action
810 - Not enabling limit-connect now allows CONNECT requests to all ports.
811 In previous versions it would only allow CONNECT requests to port 443.
812 Use +limit-connect{443} if you think you need the old default behaviour.
813 - The CGI editor gets turned off after three edit requests with invalid
814 file modification timestamps. This makes life harder for attackers
815 who can leverage browser bugs to send fake Referers and intend to
816 brute-force edit URLs.
817 - Action settings for multiple patterns in the same section are
818 shared in memory. As a result these sections take up less space
819 (and are loaded slightly faster). Problem reported by Franz Schwartau.
820 - Linear white space in HTTP headers will be normalized to single
821 spaces before parsing the header's content, headers split across
822 multiple lines get merged first. This should prevent problems like:
823 * letting the session-cookies-only action slip
824 some Cookies through unmodified,
825 * only suppressing the first line of a header,
826 thus creating an invalid one, and
827 * to incorrectly block headers with valid timestamps
828 that weren't properly recognized.
829 Headers that could trigger these problems are unlikely to appear
830 in "normal" web traffic, but could be intentionally generated to
831 fool some of Privoxy's header parsers.
832 - Host information is gathered outside the main thread so it's less
833 likely to delay other incoming connections if the host is misconfigured.
834 - New config option "hostname" to use a hostname other than
835 the one returned by the operating system. Useful to speed-up responses
836 for CGI requests on misconfigured systems. Requested by Max Khon.
837 - The CGI editor supports the "disable all filters of this type"
838 directives "-client-header-filter", "-server-header-filter",
839 "-client-header-tagger" and "-server-header-tagger".
840 - Fixed false-positives with the link-by-url filter and URLs that
841 contain the pattern "/jump/".
842 - The less-download-windows filter no longer messes
843 "Content-Type: application/x-shockwave-flash" headers up.
844 - In the show-url-info page's "Final results" section active and
845 inactive actions are listed separately. Patch provided by Lee.
846 - The GNUmakefile supports the DESTDIR variable. Patch for
847 the install target submitted by Radoslaw Zielinski.
848 - Embedding the content of configuration files in the show-status
849 page is significantly faster now. For a largish action file (1 MB)
850 a speedup of about 2450 times has been measured. This is mostly
851 interesting if you are using large action files or regularly use
852 Privoxy-Regression-Test while running Privoxy through Valgrind,
853 for stock configuration files it doesn't really matter.
854 - If zlib support is unavailable and there are content
855 filters active but the prevent-compression action is disabled,
856 the show-url-info page includes a warning that compression
857 might prevent filtering.
858 - The show-url-info page provides an OpenSearch Description that
859 allows to access the page through browser search plugins.
860 - Custom client-header filters that rewrite the request line
861 incorrectly no longer cause Privoxy to crash. Reported by din_a4.
862 - The obsolete kill-popups action has been removed as the
863 PCRS-based popup filters can do the same and are slightly
865 - The inspect-jpegs action has been removed.
866 - The send-wafer and send-vanilla-wafer actions have been removed.
867 They weren't particular useful and their behaviour could be emulated
868 with add-header anyway.
869 - Privoxy-Regression-Test has been significantly improved.
870 - Most sections in the default.action file contain tests for
871 Privoxy-Regression-Test to verify that they are working as intended.
872 - Parts of Privoxy have been refactored to increase maintainability.
873 - Building with zlib (if available) is done by default.
875 *** Version 3.0.8 ***
877 - Fixed a small memory leak when listen-address only specifies the port.
878 - The source tar balls now include Privoxy-Regression-Test which
879 (upon other things) can be used to automatically detect some
880 packaging problems. Packagers are welcome to give it a try.
881 - Reverted a change in 3.0.7 that caused path patterns to be checked
882 even if the host pattern match already failed. While this doesn't
883 noticeable affect the performance, it makes it less likely to run
884 out of stack space with overly-complex path patterns the user might
886 - Updated the msn, yahoo and google filters to work as advertised again.
887 - The warning message shown by the show-status CGI page is easier to
888 understand. Previously it wasn't clear that the error message
889 is shown below the invalid directive. (Reported by Lee)
890 - When regenerating Content-Disposition headers the more common
891 spelling is used for the name. Previously it was written without caps.
892 - Less confusing log message if the content type isn't overwritten
893 because force-text-type wasn't used but the old type doesn't look
894 like content that would be filtered normally.
895 - Better log messages if the user tries to execute filters that
897 - Treat the non-standard Request-Range headers like standard range
898 headers and suppress them if content filtering is enabled.
899 - Prevent the log messages for CONNECT requests to unacceptable
900 ports from printing the limit-connect argument as [null] if
901 limit-connect hasn't been explicitly enabled.
902 - Don't disable the mingw32 log window if the logfile directive
903 isn't used. While it was an intentional change in 3.0.7 at least
904 one user perceived it as a regression and the same effect can
905 be achieved by disabling all debug directives.
906 - Fixed two minor problems related to the win32 build process: a css
907 file was not being in the installer and the trustfile comment in the
908 config.txt referenced a nonexisting file
909 - Minor documentation fixes.
911 *** Version 3.0.7 Beta ***
913 - Added zlib support to filter content with gzip and deflate
914 encoding. (Patch provided by Wil Mahan)
915 - Dedicated filters and actions are used for header filtering.
916 "filter-client-headers" and "filter-client-headers" are no longer
917 supported, use server-header-filter{} and client-header-filter{}
919 - Tags can be used to change actions based on HTTP headers.
920 - New server-header filter: less-download-windows.
921 - New client-header taggers: css-requests, image-requests,
922 client-ip-address, http-method, allow-post, complete-url,
923 user-agent and privoxy-control.
924 - New server-header taggers: content-type and privoxy-control.
925 - The forward-override{} action allows to change the forwarding
926 settings through the action files, for example based on client
927 headers like the User-Agent, or the request origin.
928 - Socks errors are no longer handled by the CGI page for
929 DNS resolution failures.
930 - CGI pages use favicons to signal whether they are error
931 or control pages. This is useful if you rely heavily on
933 - The show-url-info CGI page shows the forwarding settings.
934 - "Crunch!" log messages (used when Privoxy answers requests
935 by itself) now also contain the reason.
936 - Allow to rewrite the request destination behind the client's back.
937 - Fix socks requests on big-endian platforms. Patch provided by Song Weijia.
938 - Fixes possible deadlocks and crashes on OpenBSD.
939 Patch provided by Ralf Horstmann.
940 - The CGI action editor allows to edit actionfiles with previously
941 forbidden characters like dots.
942 - New trust entries are saved with a comment that contains the
943 trusted referring URL (Suggested by Daniel Griscom).
944 - Filter descriptions are HTML encoded automatically.
945 - New config option "split-large-forms" to work
946 around a browser bug that caused IE6 and IE7 to ignore
947 the Submit button on the edit-actions-for-url CGI page.
948 - New config option "allow-cgi-request-crunching" to allow
949 requests for Privoxy's CGI pages to be blocked, redirected
950 or (un)trusted like ordinary requests.
951 - Empty filter files no longer interrupt the filtering process
952 prematurely and are correctly listed on the show-status CGI page.
953 - New config option "accept-intercepted-requests" to combine
954 Privoxy with any packet filter to build an intercepting proxy
955 for HTTP/1.1 requests (and for HTTP/1.0 requests with Host header set).
956 - fast-redirects{} catch redirects to https URLs as well.
957 - redirect{s@foo@bar@} can be used to redirect to a rewritten
958 version of the original URL.
959 - Trap unsupported gopher proxy requests.
960 - Fixed a bug in the User Manual delivery on Windows
961 (mingw32 only). Images now show up correctly and HTML
962 pages are no longer padded with garbage data.
963 - Fixed several minor memory leaks, most of them discovered with Valgrind.
964 - Only unlink the pidfile if it's actually used.
965 - Retries after connection problems with forced requests
966 aren't blocked again.
967 - On Unix SIGABRT causes a core dump as expected and is no
968 longer treated as normal shutdown signal.
969 - The "access denied" CGI page is more descriptive and
970 allows retries to circumvent the referrer check.
971 - Updated PCRS to handle unexpected PCRE errors properly.
972 Fixed crashes that could occur if Privoxy was build
973 with external PCRE versions newer than Privoxy's internal
974 one. (Reported by Chung-chieh Shan)
975 - Fixed crashes with null bytes in PCRS replacement strings
976 (Patch provided by Felix Gröbert).
977 - Fixed crashes with header time randomization on mingw32.
978 - The CGI style sheet is no longer delivered if the referring
979 page isn't a Privoxy CGI page. This prevents a JavaScript-based
980 Privoxy detection "attack". Note that detecting Privoxy is
981 still possible through other ways and Privoxy was never intended
982 to be invisible anyway.
983 - Added support for AmigaOS 4, fixed build for AmigaOS 3.x.
984 - The show-url-info CGI page displays a warning if Privoxy
985 is currently toggled off.
986 - The show-status CGI page suppresses the edit button
987 for action files if Privoxy has no write access.
988 - Most CGI error pages react properly to HEAD requests.
989 - Requests with RFC 3253 HTTP methods (used by Subversion)
990 are accepted. (Patch provided by Petr Kadlec)
991 - New config option "templdir" to change the location
992 of the CGI templates to make sure customized templates
994 - Better handling of "HTTP/1.1 100 Continue" responses.
995 - The background of the PNG pattern is transparent.
996 - Fixed XML syntax errors caused by banners-by-size and banners-by-url.
997 - Fixed crashes and possible action file corruptions
998 when lines containing hashes are written through the CGI editor.
999 - Supports dynamic filters which can contain variables.
1000 - Supports tags to change the actions based on client or server headers.
1001 - Incorrect actions are logged before program termination.
1002 - The "actionsfile" syntax in the configuration file is consistent
1003 with the rest of the configuration options and requires the
1004 whole file name. This is an incompatible change, if you use
1005 an old configuration file you might have to append ".action"
1006 to your "actionsfile" directives.
1007 - With the configuration file option "enforce-blocks" the
1008 "go there anyway" mechanism can be disabled without recompiling
1010 - More precise error messages in case of incorrect acl syntax.
1011 - Logs a warning if filtering is enabled but impossible due
1012 to lack of zlib support or use of the prevent-compression action.
1013 - Less noisy handling of Cookie:" and "Connection:" headers.
1014 - Improved error messages in case of connection problems.
1015 - Fix a command-line-parsing bug that was introduced before 3.0.5
1016 beta and caused Privoxy to treat the last argument as configuration
1017 file if no configuration file was specified.
1018 - Treat unknown command line options as fatal errors instead
1019 of silently ignoring them.
1020 - Use string functions with length checks more often.
1021 - Don't log CONNECT requests twice.
1022 - Allow to log the source address for ACL-related connection drops.
1023 - Don't ignore applying filters if the server didn't
1024 specify a Content-Type. Bug reported by Amuro Namie.
1025 - Rejected CONNECT requests are logged with log level info
1026 (enabled by default) and the reason for the block.
1027 - New command line option "--pre-chroot-nslookup hostname" to
1028 intialize the resolver library before chroot'ing. On some systems this
1029 reduces the number of files that must be copied into the chroot tree.
1030 (Patch provided by Stephen Gildea)
1031 - Fix a long-standing memory corruption bug that could cause
1032 Privoxy to overwrite a single byte in memory it didn't explicitly
1033 allocate (but that probably was allocated anyway due to bucket size).
1034 - Send template-based CGI pages as HTTP/1.1 unless the client
1036 - Let the first line in connection established responses
1037 end in \r\n as required by RFC1945. Reported by Bert van Leeuwen.
1038 - If no log file has been specified, disable logging instead of logging
1040 - Don't block stderr when in daemon mode.
1041 - Ignore missing zero-chunks when filtering chunk-encoded content.
1042 Earlier Privoxy versions would buffer and then forward the content
1043 unmodified which caused some browsers to simply show empty pages.
1044 - Fix double free in cgi_edit_actions_list(). Reported by Venustech AD-LAB.
1045 - The code to add X-Forwarded-For headers when the hide-forwarded-for-headers
1046 action isn't being used has been removed.
1047 - Fixed trustfile feature which previously didn't work without FEATURE_TOGGLE.
1049 - Minor code clean-ups, filter and action file updates.
1050 (Some of them reported by Davide Alberani, Markus Elfring,
1051 Stefan Huehner and Adam Piggott)
1053 *** Version 3.0.6 ***
1055 - New content filters: no-ping, google, msn, yahoo and blogspot.
1056 - New header filters: x-httpd-php-to-html, html-to-xml, xml-to-html
1057 and hide-tor-exit-notation.
1058 - The special header "X-Filter: No" now disables header filtering as well.
1059 - Improved the filters img-reorder, js-annoyances, webbugs,
1060 banners-by-size, banners-by-link and ie-exploits to make them
1061 less likely to break anything.
1062 - Removed outdated URL patterns in default.action and added new ones.
1063 - Added redirection from http://p.p/user-manual to http://p.p/user-manual/

1072 http://www.fabiankeil.de/sourcecode/privoxy/. Includes the
1073 following new or significantly improved actions (among many
1074 other improvements):
1076 content-type-overwrite{}
1077 crunch-client-header{string}
1078 crunch-if-none-match
1079 crunch-server-header{string}
1080 fast-redirects{check-decoded-url}
1081 filter-client-headers
1082 filter-server-headers
1084 handle-as-empty-document
1085 hide-accept-language{}
1086 hide-content-disposition{}
1087 hide-if-modified-since
1088 hide-referrer{conditional-block}
1089 overwrite-last-modified{}
1091 treat-forbidden-connects-like-blocks

1116 - Fixed yet another two memory leaks. Process growth seems stopped now.
1117 - Further tightened security against malicious toggle-off links.
1118 - Excluded text/plain MIME types from filtering. This fixes a
1119 couple of client-crashing, download corruption and
1120 Privoxy performance issues, whose root cause lies in
1121 web servers labelling content of unknown type as text/plain.
1122 - Assorted fixes for POSIX compliance, signal handling, graceful
1123 termination, compiler warnings, OSX support, Win32 systray,
1124 error logging, hostname wildcards, correct detection of NetBSD.
1125 - Workarounds for client (iTunes etc) and server (PHP < 4.2.3) bugs

1143 html-annoyances, content-cookies and fun filters
1144 - Replaced filter "popups" by choice between two modes:
1145 - "unsolicited-popups" tries to catch only the unsolicited ones
1146 - "all-popups" tries to kill them all (as before)
1147 - New filter "tiny-textforms" Help those tiny or hard-wrap textareas.
1148 - New filter "jumping-windows" that prevents windows from resizing
1149 and moving themselves
1150 - New filter "demoronizer" which fixes MS's abuse of std charsets
1151 (common cases anyway).
1152 - Replaced "nimda" with more general "ie-exploits" filter in which
1153 all filters for exploits shall be collected
1154 - Improved cookie logging
1155 - Rewrote make install target. Added uninstall and install-strip
1157 - Fixed a potential (application-level, NOT OS-level!) security
1158 problem involving remote toggling and action file manipulation
1159 by mailicious websites.
1160 - Added ability to chroot (thanks to Sviatoslav Sviridov)

1183 - Major revamp of default.action to get rid of years of cruft.
1184 - Same for default.filter

1209 - Various other minor fixes.
1211 *** Version 2.9.13 Beta ***
1213 - *NEWS*: The project has been renamed to Privoxy! The new name is
1214 reflected throughout (file locations, etc).
1215 - ijb.action is now default.action. re_filterfile is now
1217 - http://i.j.b/ is now http://p.p/

1245 - Fix restart failure where sockets were in TIME_WAIT.
1246 - Fixes for actions cgi editor, make sure we have right file.
1247 - A --pidfile command line option now, in addition to --help,
1248 --version, --no-daemon, --user and configfile. --no-daemon replaces
1249 the former -d option and _DEBUG define. --user will drop privileges
1250 to the specified user.
1251 - Signal handling cleanups (*nix).
1252 - CGI actions editor improvements and fixes.

1285 - Many other minor bugfixes
1286 - Start a ChangeLog :)
1290 *** Version 2.9.3 pre-Alpha Changes ***
1292 - Amiga support (completely untested by me - I don't have an Amiga)
1293 - "tinygif 3" support (redirects blocked images to a specified URL, so
1294 the browser doesn't have to load and cache many copies of the same
1296 - one case where there were both local and global "referrer" variables
1297 (yuck!) clarified by renaming the local one to "refer".
1298 - Fixed some places where close() was used instead of close_socket().
1299 Thanks to Jörg Strohmayer (joergs at users.sourceforge.net) for these.
1300 - Temporary hack to get FORCE_LOAD to work with IE. I just lowercased the
1301 FORCE_LOAD_PREFIX. Needs fixing properly.
1302 - Most URLs hardcoded into Junkbuster were changed to go through a script
1303 e.g. http://ijbswa.sourceforge.net/redirect.php?v=2.9.3&to=faq
1304 The only other URLs left are the GNU GPL:
1305 http://www.fsf.org/copyleft/gpl.html
1307 http://ijbswa.sourceforge.net/
1308 ... and various URLs which will be intercepted by Junkbuster anyway.
1309 TODO: Still need to do something with the URLs in Junkbuster Corp's
1310 copyright/trademark notice on the bottom of the show-proxy-args page.
1311 - PCRE or GNU Regex is now a #define option.
1314 *** Version 2.9.2 pre-Alpha Changes ***
1316 - Andreas applied the latest version of the FORCE patch.
1319 *** Version 2.9.1 pre-Alpha Changes ***
1321 - in parsers.c, fixed two #ifdef FORCE to #ifdef FORCE_LOAD
1322 (BTW: I think FORCE is precise enough, since loading remote
1323 data is the whole purpose of a proxy..)
1324 - Set the FORCE_PREFIX (back) to 'IJB-FORCE-LOAD-'. While 'noijb.'
1325 is more elegant and looks like a hostname in the URL, it doesn't
1326 make clear to the inexperienced user that the proxy is bypassed. It
1327 also has a higher name collision risk.
1328 - Filled in the function header templates for my functions in
1329 parsers.c (again). They obviously got lost in our current
1331 - Cut the credit for the §-referrer-option from the config file,
1332 that Stefan had placed there.
1333 - Improved the re_filterfile
1336 *** Version 2.9.0 pre-Alpha Changes ***
1338 - Now use PCRE, not GNU REGEX. I have not yet had chance to check the
1339 syntax of the block/image/cookie file to ensure that they match what
1340 is expected - however they seem to work.
1341 - Replaced "configure" script with one generated by "autoconf". Also
1342 use a header "config.h" (was ijbconfig.h in my previous release) for
1343 the #defines. "config.h" is now generated with "autoheader" from
1344 "acconfig.h" and "configure.in". (Note that to install you do not
1345 need autoconf or autoheader - just run "./configure".)
1346 To see command-line options, run "./configure --help".
1347 This is my first ever autoconf script, so it has some rough edges
1348 (how PCRE is handled is the roughest).
1349 - Error logging code replaced with new module errlog.c, based on the
1350 one from JunkbusterMT (but with the threading code removed).
1351 - Most of Rodney's 0.21 and 0.21A patches applied. (Marked *). I did not
1352 apply all of these, since I had already independently done conditional
1353 popup file, conditional image file, and integration of popup code.
1354 - ACL, Jar and trust files conditionally compiled.
1355 - New source file headers.
1356 - Various cosmetic changes. (But I have not consistently ordered the
1357 config files - I think that's worthwhile, but it's 1am and I want to
1359 - RCS tags on .h files.
1360 - RCS tags are const char[] rather than const char *. (Saves 4 bytes
1362 - VC++ project files renamed to vc_junkbuster.*.
1363 - show-proxy-args now shows status of all conditionals, not just REGEX
1364 - Various functions moved around. Most notably all the system-specific
1365 sockets code which was spread between jcc.c, bind.c, and connect.c,
1366 has been moved to "jbsockets.c". The non-system-specific code from
1367 connect.c and socks4.c has been movet to "gateway.c". Also, the
1368 config file loader and the global variables it writes to have been
1369 moved to "loadcfg.c". (Maybe this should go into loaders.c?)
1370 And candidate for the "worst filename ever" award is "miscutil.c",
1371 which contains, well, miscellaneous utility functions like zalloc.
1372 (Suggestions for a better name for this file are welcome!)
1373 - Loaders now use a common function to read a line and skip comments,
1374 and this function also stores the proxy_args.
1375 - Added ./junkbuster --help (Not for Win32 GUI)
1376 - Added ./junkbuster --version (Not for Win32 GUI)
1377 - Win32 resources are now all marked as "U.S. English", rather than
1378 being a mix of "U.S. English", "U.K. English" and "Irish English".
1379 - Version number changes to 2.9.0
