4 *** Version 3.0.18 Stable ***
7 - If a generated redirect URL contains characters RFC 3986 doesn't
8 permit, they are (re)encoded. Not doing this makes Privoxy versions
9 from 3.0.5 to 3.0.17 susceptible to HTTP response splitting (CWE-113)
10 attacks if the +fast-redirects{check-decoded-url} action is used.
11 - Fix a logic bug that could cause Privoxy to reuse a server
12 socket after it got tainted by a server-header-tagger-induced
13 block that was triggered before the whole server response had
14 been read. If keep-alive was enabled and the request following
15 the blocked one was to the same host and using the same forwarding
16 settings, Privoxy would send it on the tainted server socket.
17 While the server would simply treat it as a pipelined request,
18 Privoxy would later on fail to properly parse the server's
19 response as it would try to parse the unread data from the
20 first response as server headers for the second one.
21 Regression introduced in 3.0.17.
22 - When implying keep-alive in client_connection(), remember that
23 the client didn't. Fixes a regression introduced in 3.0.13 that
24 would cause Privoxy to wait for additional client requests after
25 receiving a HTTP/1.1 request with "Connection: close" set
26 and connection sharing enabled.
27 With clients which terminates the client connection after detecting
28 that the whole body has been received it doesn't really matter,
29 but with clients that don't the connection would be kept open until
31 - Fix a subtle race condition between prepare_csp_for_next_request()
32 and sweep(). 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 So far this has only been reproduced while stress testing in
37 valgrind while touching action files in a loop. It's unlikely
38 to have caused any actual problems in the real world.
39 - Disable filters if SDCH compression is used unless filtering is forced.
40 If SDCH was combined with a supported compression algorithm, Privoxy
41 previously could try to decompress it and ditch the Content-Encoding
42 header even though the SDCH compression wasn't dealt with.
43 Reported by zebul666 in #3225863.
44 - Make a copy of the --user value and only mess with that when splitting
45 user and group. On some operating systems modifying the value directly
46 is reflected in the output of ps and friends and can be misleading.
47 Reported by zepard in #3292710.
48 - If forwarded-connect-retries is set, only retry if Privoxy is actually
49 forwarding the request. Previously direct connections would be retried
51 - Fixed a small memory leak when retrying connections with IPv6
53 - Remove an incorrect assertion in compile_dynamic_pcrs_job_list()
54 It could be triggered by a pcrs job with an invalid pcre
55 pattern (for example one that contains a lone quantifier).
56 - If the --user argument user[.group] contains a dot, always bail out
57 if no group has been specified. Previously the intended, but undocumented
58 (and apparently untested), behaviour was to try interpreting the whole
59 argument as user name, but the detection was flawed and checked for '0'
60 instead of '\0', thus merely preventing group names beginning with a zero.
61 - In html_code_map[], use a numeric character reference instead of '
62 which wasn't standardized before XHTML 1.0.
63 - Fix an invalid free when compiled with FEATURE_GRACEFUL_TERMINATION
64 and shut down through http://config.privoxy.org/die
65 - In get_actions(), fix the "temporary" backwards compatibility hack
66 to accept block actions without reason.
67 It also covered other actions that should be rejected as invalid.
68 Reported by Billy Crook.
70 - General improvements:
71 - Privoxy can (re)compress buffered content before delivering
72 it to the client. Disabled by default as most users wouldn't
74 - The +fast-redirects{check-decoded-url} action checks URL
75 segments separately. If there are other parameters behind
76 the redirect URL, this makes it unnecessary to cut them off
77 by additionally using a +redirect{} pcrs command.
78 Initial patch submitted by Jamie Zawinski in #3429848.
79 - When loading action sections, verify that the referenced filters
80 exist. Currently missing filters only result in an error message,
81 but eventually the severity will be upgraded to fatal.
82 - Allow to bind to multiple separate addresses.
83 Patch set submitted by Petr Pisar in #3354485.
84 - Set socket_error to errno if connecting fails in rfc2553_connect_to().
85 Previously rejected direct connections could be incorrectly reported
86 as DNS issues if Privoxy was compiled with IPv6 support.
87 - Adjust url_code_map[] so spaces are replaced with %20 instead of '+'
88 While '+' can be used by client's submitting form data, this is not
89 actually what Privoxy is using the lookups for. This is more of a
90 cosmetic issue and doesn't fix any known problems.
91 - When compiled without FEATURE_FAST_REDIRECTS, do not silently
92 ignore +fast-redirect{} directives
93 - Added a workaround for GNU libc's strptime() reporting negative
94 year values when the parsed year is only specified with two digits.
95 On affected systems cookies with such a date would not be turned
96 into session cookies by the +session-cookies-only action.
97 Reported by Vaeinoe in #3403560
98 - Fixed bind failures with certain GNU libc versions if no non-loopback
99 IP address has been configured on the system. This is mainly an issue
100 if the system is using DHCP and Privoxy is started before the network
101 is completely configured.
102 Reported by Raphael Marichez in #3349356.
103 Additional insight from Petr Pisar.
104 - Privoxy log messages now use the ISO 8601 date format %Y-%m-%d.
105 It's only slightly longer than the old format, but contains
106 the full date including the year and allows sorting by date
107 (when grepping in multiple log files) without hassle.
108 - In get_last_url(), do not bother trying to decode URLs that do
109 not contain at least one '%' sign. It reduces the log noise and
110 a number of unnecessary memory allocations.
111 - In case of SOCKS5 failures, dump the socks response in the log message.
112 - Simplify the signal setup in main().
113 - Streamline socks5_connect() slightly.
114 - In socks5_connect(), require a complete socks response from the server.
115 Previously Privoxy didn't care how much data the server response
116 contained as long as the first two bytes contained the expected
117 values. While at it, shrink the buffer size so Privoxy can't read
118 more than a whole socks response.
119 - In chat(), do not bother to generate a client request in case of
120 direct CONNECT requests. It will not be used anyway.
121 - Reduce server_last_modified()'s stack size.
122 - Shorten get_http_time() by using strftime().
123 - Constify the known_http_methods pointers in unknown_method().
124 - Constify the time_formats pointers in parse_header_time().
125 - Constify the formerly_valid_actions pointers in action_used_to_be_valid().
126 - Introduce a GNUMakefile MAN_PAGE variable that defaults to privoxy.1.
127 The Debian package uses section 8 for the man page and this
128 should simplify the patch.
129 - Deduplicate the INADDR_NONE definition for Solaris by moving it to jbsockets.h
130 - In block_url(), ditch the obsolete workaround for ancient Netscape versions
131 that supposedly couldn't properly deal with status code 403.
132 - Remove a useless NULL pointer check in load_trustfile().
133 - Remove two useless NULL pointer checks in load_one_re_filterfile().
134 - Change url_code_map[] from an array of pointers to an array of arrays
135 It removes an unnecessary layer of indirection and on 64bit system reduces
136 the size of the binary a bit.
137 - Fix various typos. Fixes taken from Debian's 29_typos.dpatch by Roland Rosenfeld.
138 - Add a dok-tidy GNUMakefile target to clean up the messy HTML
139 generated by the other dok targets.
140 - GNUisms in the GNUMakefile have been removed.
141 - Change the HTTP version in static responses to 1.1
142 - Synced config.sub and config.guess with upstream
143 2011-11-11/386c7218162c145f5f9e1ff7f558a3fbb66c37c5.
144 - Add a dedicated function to parse the values of toggles. Reduces duplicated
145 code in load_config() and provides better error handling. Invalid or missing
146 toggle values are now a fatal error instead of being silently ignored.
147 - Terminate HTML lines in static error messages with \n instead of \r\n.
148 - Simplify cgi_error_unknown() a bit.
149 - In LogPutString(), don't bother looking at pszText when not
150 actually logging anything.
151 - Change ssplit()'s fourth parameter from int to size_t.
152 Fixes a clang complaint.
153 - Add a warning that the statistics currently can't be trusted.
154 Mention Privoxy-Log-Parser's --statistics option as
155 an alternative for the time being.
156 - In rfc2553_connect_to(), start setting cgi->error_message on error.
157 - Change the expected status code returned for http://p.p/die depending
158 on whether or not FEATURE_GRACEFUL_TERMINATION is available.
159 - In cgi_die(), mark the client connection for closing.
160 If the client will fetch the style sheet through another connection
161 it gets the main thread out of the accept() state and should thus
162 trigger the actual shutdown.
163 - Add a proper CGI message for cgi_die().
164 - Don't enforce a logical line length limit in read_config_line().
165 - Slightly refactor server_last_modified() to remove useless gmtime*() calls.
166 - In get_content_type(), also recognize '.jpeg' as JPEG extension.
167 - Add '.png' to the list of recognized file extensions in get_content_type().
168 - In block_url(), consistently use the block reason "Request blocked by Privoxy"
169 In two places the reason was "Request for blocked URL" which hides the
170 fact that the request got blocked by Privoxy and isn't necessarily
171 correct as the block may be due to tags.
172 - In listen_loop(), reload the configuration files after accepting
173 a new connection instead of before.
174 Previously the first connection that arrived after a configuration
175 change would still be handled with the old configuration.
176 - In chat()'s receive-data loop, skip a client socket check if
177 the socket will be written to right away anyway. This can
178 increase the transfer speed for unfiltered content on fast
180 - The socket timeout is used for SOCKS negotiations as well which
181 previously couldn't timeout.
182 - Don't keep the client connection alive if any configuration file
183 changed since the time the connection came in. This is closer to
184 Privoxy's behaviour before keep-alive support for client connection
185 has been added and also less confusing in general.
186 - Treat all Content-Type header values containing the pattern
187 'script' as a sign of text. Reported by pribog in #3134970.
189 - Action file improvements:
190 - Moved the site-specific block pattern section below the one for the
191 generic patterns so for requests that are matched in both, the block
192 reason for the domain is shown which is usually more useful than showing
193 the one for the generic pattern.
194 - Remove -prevent-compression from the fragile alias. It's no longer
195 used anywhere by default and isn't known to break stuff anyway.
196 - Add a (disabled) section to block various Facebook tracking URLs.
197 Reported by Dan Stahlke in #3421764.
198 - Add a (disabled) section to rewrite and redirect click-tracking
199 URLs used on news.google.com.
200 Reported by Dan Stahlke in #3421755.
201 - Unblock linuxcounter.net/.
202 Reported by Dan Stahlke in #3422612.
203 - Block 'www91.intel.com/' which is used by Omniture.
204 Reported by Adam Piggott in #3167370.
205 - Disable the handle-as-empty-doc-returns-ok option and mark it as deprecated.
206 Reminded by tceverling in #2790091.
207 - Add ".ivwbox.de/" to the "Cross-site user tracking" section.
208 Reported by Nettozahler in #3172525.
209 - Unblock and fast-redirect ".awin1.com/.*=http://".
210 Reported by Adam Piggott in #3170921.
211 - Block "b.collective-media.net/".
212 - Widen the Debian popcon exception to "qa.debian.org/popcon".
213 Seen in Debian's 05_default_action.dpatch by Roland Rosenfeld.
214 - Block ".gemius.pl/" which only seems to be used for user tracking.
215 Reported by johnd16 in #3002731. Additional input from Lee and movax.
216 - Disable banners-by-size filters for '.thinkgeek.com/'.
217 The filter only seems to catch pictures of the inventory.
218 - Block requests for 'go.idmnet.bbelements.com/please/showit/'.
219 Reported by kacperdominik in #3372959.
220 - Unblock adainitiative.org/.
221 - Add a fast-redirects exception for '.googleusercontent.com/.*=cache'.
222 - Add a fast-redirects exception for webcache.googleusercontent.com/.
223 - Unblock http://adassier.wordpress.com/ and http://adassier.files.wordpress.com/.
225 - Filter file improvements:
226 - Let the yahoo filter hide '.ads'.
227 - Let the msn filter hide overlay ads for Facebook 'likes' in search
228 results and elements with the id 's_notf_div'. They only seem to be
229 used to advertise site 'enhancements'.
230 - Let the js-events filter additionally disarm setInterval().
231 Suggested by dg1727 in #3423775.
233 - Documentation improvements:
234 - Clarify the effect of compiling Privoxy with zlib support.
235 Suggested by dg1727 in #3423782.
236 - Point out that the SourceForge messaging system works like a black
237 hole and should thus not be used to contact individual developers.
238 - Mention some of the problems one can experience when not explicitly
239 configuring an IP addresses as listen address.
240 - Explicitly mention that hostnames can be used instead of IP addresses
241 for the listen-address, that only the first address returned will be
242 used and what happens if the address is invalid.
243 Requested by Calestyo in #3302213.
245 - Log message improvements:
246 - If only the server connection is kept alive, do not pretend to
247 wait for a new client request.
248 - Remove a superfluous log message in forget_connection().
249 - In chat(), properly report missing server responses as such
250 instead of calling them empty.
251 - In forwarded_connect(), fix a log message nobody should ever see.
252 - Fix a log message in socks5_connect(), a failed write operation
253 was logged as failed read operation.
254 - Let load_one_actions_file() properly complain about a missing
255 '{' at the beginning of the file.
256 Simply stating that a line is invalid isn't particularly helpful.
257 - Do not claim to listen on a socket until Privoxy actually does.
258 Patch submitted by Petr Pisar #3354485
259 - Prevent a duplicated LOG_LEVEL_CLF message when sending out
260 the "no-server-data" response.
261 - Also log the client socket when dropping a connection.
262 - Include the destination host in the 'Request ... marked for
263 blocking. limit-connect{...} doesn't allow CONNECT ...' message
264 Patch submitted by Saperski in #3296250.
265 - Prevent a duplicated log message if none of the resolved IP
266 addresses were reachable.
267 - In connect_to(), do not pretend to retry if forwarded-connect-retries
269 - When a specified user or group can't be found, put the name in
270 single-quotes when logging it.
271 - In rfc2553_connect_to(), explain getnameinfo() errors better.
272 - Remove a useless log message in chat().
273 - When retrying to connect, also log the maximum number of connection
275 - Rephrase a log message in compile_dynamic_pcrs_job_list().
276 Divide the error code and its meaning with a colon. Call the pcrs
277 job dynamic and not the filter. Filters may contain dynamic and
278 non-dynamic pcrs jobs at the same time. Only mention the name of
279 the filter or tagger, but don't claim it's a filter when it could
281 - In a fatal error message in load_one_actions_file(), cover both
282 URL and TAG patterns.
283 - In pcrs_strerror(), properly report unknown positive error code
284 values as such. Previously they were handled like 0 (no error).
285 - In compile_dynamic_pcrs_job_list(), also log the actual error code as
286 pcrs_strerror() doesn't handle all errors reported by pcre.
287 - Don't bother trying to continue chatting if the client didn't ask for it.
288 Reduces log noise a bit.
289 - Make two fatal error message in load_one_actions_file() more descriptive.
290 - In cgi_send_user_manual(), log when rejecting a file name due to '/' or '..'.
291 - In load_file(), log a message if opening a file failed.
292 The CGI error message alone isn't too helpful.
293 - In connection_destination_matches(), improve two log messages
294 to help understand why the destinations don't match.
295 - Rephrase a log message in serve(). Client request arrival
296 should be differentiated from closed client connections now.
297 - In serve(), log if a client connection isn't reused due to a
298 configuration file change.
299 - Let mark_server_socket_tainted() always mark the server socket tainted,
300 just don't talk about it in cases where it has no effect. It doesn't change
301 Privoxy's behaviour, but makes understanding the log file easier.
304 - Added a --disable-ipv6-support switch for platforms where support
305 is detected but doesn't actually work.
306 - Do not check for the existence of strerror() and memmove() twice
307 - Remove a useless test for setpgrp(2). Privoxy doesn't need it and
308 it can cause problems when cross-compiling.
309 - Rename the --disable-acl-files switch to --disable-acl-support.
310 Since about 2001, ACL directives are specified in the standard
312 - Update the URL of the 'Removing outdated PCRE version after the
313 next stable release' posting. The old URL stopped working after
314 one of SF's recent site "optimizations". Reported by Han Liu.
316 - Privoxy-Regression-Test:
317 - Added --shuffle-tests option to increase the chances of detection race conditions.
318 - Added a --local-test-file option that allows to use Privoxy-Regression-Test without Privoxy.
319 - Added tests for missing socks4 and socks4a forwarders.
320 - The --privoxy-address option now works with IPv6 addresses containing brackets, too.
321 - Perform limited sanity checks for parameters that are supposed to have numerical values.
322 - Added a --sleep-time option to specify a number of seconds to
323 sleep between tests, defaults to 0.
324 - Disable the range-requests tagger for tests that break if it's enabled.
325 - Log messages use the ISO 8601 date format %Y-%m-%d.
326 - Fix spelling in two error messages.
327 - In the --help output, include a list of supported tests and their default levels.
328 - Adjust the tests to properly deal with FEATURE_TOGGLE being disabled.
330 - Privoxy-Log-Parser:
331 - Perform limited sanity checks for command line parameters that
332 are supposed to have numerical values.
333 - Implement a --unbreak-lines-only option to try to revert MUA breakage.
334 - Accept and highlight: Added header: Content-Encoding: deflate
335 - Accept and highlight: Compressed content from 29258 to 8630 bytes.
336 - Accept and highlight: Client request arrived in time on socket 21.
337 - Highlight: Didn't receive data in time: a.fsdn.com:443
338 - Accept log messages with ISO 8601 time stamps, too.
341 - Bump generated Firefox version to 8.0.
342 - Only randomize the release date if the new --randomize-release-date
343 option is enabled. Firefox versions after 4 use a fixed date string
346 *** Version 3.0.17 Stable ***
348 - Fixed last-chunk-detection for responses where the body was small
349 enough to be read with the headers, causing Privoxy to wait for the
350 end of the content until the server closed the connection or the
351 request timed out. Reported by "Karsten" in #3028326.
352 - Responses with status code 204 weren't properly detected as body-less
353 like RFC2616 mandates. Like the previous bug, this caused Privoxy to
354 wait for the end of the content until the server closed the connection
355 or the request timed out. Fixes #3022042 and #3025553, reported by a
356 user with no visible name. Most likely also fixes a bunch of other
357 AJAX-related problem reports that got closed in the past due to
358 insufficient information and lack of feedback.
359 - Fixed an ACL bug that made it impossible to build a blacklist.
360 Usually the ACL directives are used in a whitelist, which worked
361 as expected, but blacklisting is still useful for public proxies
362 where one only needs to deny known abusers access.
363 - Added LOG_LEVEL_RECEIVED to log the not-yet-parsed data read from the
364 network. This should make debugging various parsing issues a lot easier.
365 - The IPv6 code is enabled by default on Windows versions that support it.
366 Patch submitted by oCameLo in #2942729.
367 - In mingw32 versions, the user.filter file is reachable through the
368 GUI, just like default.filter is. Feature request 3040263.
369 - Added the configure option --enable-large-file-support to set a few
370 defines that are required by platforms like GNU/Linux to support files
371 larger then 2GB. Mainly interesting for users without proper logfile
373 - Logging with "debug 16" no longer stops at the first nul byte which is
374 pretty useless. Non-printable characters are replaced with their hex value
375 so the result can't span multiple lines making parsing them harder then
377 - Privoxy logs when reading an action, filter or trust file.
378 - Fixed incorrect regression test markup which caused a test in
379 3.0.16 to fail while Privoxy itself was working correctly.
380 While Privoxy accepts hide-referer, too, the action name is actually
381 hide-referrer which is also the name used one the final results page,
382 where the test expected the alias.
384 - CGI interface improvements:
385 - In finish_http_response(), continue to add the 'Connection: close'
386 header if the client connection will not be kept alive.
387 Anonymously pointed out in #2987454.
388 - Apostrophes in block messages no longer cause parse errors
389 when the blocked page is viewed with JavaScript enabled.
390 Reported by dg1727 in #3062296.
391 - Fix a bunch of anchors that used underscores instead of dashes.
392 - Allow to keep the client connection alive after crunching the previous request.
393 Already opened server connections can be kept alive, too.
394 - In cgi_show_url_info(), don't forget to prefix URLs that only contain
395 http:// or https:// in the path. Fixes #2975765 reported by Adam Piggott.
396 - Show the 404 CGI page if cgi_send_user_manual() is called while
397 local user manual delivery is disabled.
399 - Action file improvements:
400 - Enable user.filter by default. Suggested by David White in #3001830.
401 - Block .sitestat.com/. Reported by johnd16 in #3002725.
402 - Block .atemda.com/. Reported by johnd16 in #3002723.
403 - Block js.adlink.net/. Reported by johnd16 in #3002720.
404 - Block .analytics.yahoo.com/. Reported by johnd16 in #3002713.
405 - Block sb.scorecardresearch.com, too. Reported by dg1727 in #2992652.
406 - Fix problems noticed on Yahoo mail and news pages.
407 - Remove the too broad yahoo section, only keeping the
408 fast-redirects exception as discussed on ijbswa-devel@.
409 - Don't block adesklets.sourceforge.net. Reported in #2974204.
410 - Block chartbeat ping tracking. Reported in #2975895.
411 - Tag CSS and image requests with cautious and medium settings, too.
412 - Don't handle view.atdmt.com as image. It's used for click-throughs
413 so users should be able to "go there anyway".
414 Reported by Adam Piggott in #2975927.
415 - Also let the refresh-tags filter remove invalid refresh tags where
416 the 'url=' part is missing. Anonymously reported in #2986382.
417 While at it, update the description to mention the fact that only
418 refresh tags with refresh times above 9 seconds are covered.
419 - javascript needs to be blocked with +handle-as-empty-document to
420 work around Firefox bug 492459. So move .js blockers from
421 +block{Might be a web-bug.} -handle-as-empty-document to
422 +block{Might be a web-bug.} +handle-as-empty-document.
423 - ijbswa-Feature Requests-3006719 - Block 160x578 Banners.
424 - Block another omniture tracking domain.
425 - Added a range-requests tagger.
426 - Added two sections to get Flickr's Ajax interface working with
427 default pre-settings. If you change the configuration to block
428 cookies by default, you'll need additional exceptions.
429 Reported by Mathias Homann in #3101419 and by Patrick on ijbswa-users@.
431 - Documentation improvements:
432 - Explicitly mention how to match all URLs.
433 - Consistently recommend socks5 in the Tor FAQ entry and mention
434 its advantage compared to socks4a. Reported by David in #2960129.
435 - Slightly improve the explanation of why filtering may appear
437 - Grammar fixes for the ACL section.
438 - Fixed a link to the 'intercepting' entry and add another one.
439 - Rename the 'Other' section to 'Mailing Lists' and reword it
440 to make it clear that nobody is forced to use the trackers
441 - Note that 'anonymously' posting on the trackers may not always
443 - Suggest to enable debug 32768 when suspecting parsing problems.
445 - Privoxy-Log-Parser improvements:
446 - Gather statistics for ressources, methods, and HTTP versions
448 - Also gather statistics for blocked and redirected requests.
449 - Provide the percentage of keep-alive offers the client accepted.
450 - Add a --url-statistics-threshold option.
451 - Add a --host-statistics-threshold option to also gather
452 statistics about how many request where made per host.
453 - Fix a bug in handle_loglevel_header() where a 'scan: ' got lost.
454 - Add a --shorten-thread-ids option to replace the thread id with
456 - Accept and ignore: Looks like we got the last chunk together
457 with the server headers. We better stop reading.
458 - Accept and ignore: Continue hack in da house.
459 - Accept and higlight: Rejecting connection from 10.0.0.2.
460 Maximum number of connections reached.
461 - Accept and highlight: Loading actions file: /usr/local/etc/privoxy/default.action
462 - Accept and highlight: Loading filter file: /usr/local/etc/privoxy/default.filter
463 - Accept and highlight: Killed all-caps Host header line: HOST: bestproxydb.com
464 - Accept and highlight: Reducing expected bytes to 0. Marking
465 the server socket tainted after throwing 4 bytes away.
466 - Accept: Merged multiple header lines to: 'X-FORWARDED-PROTO: http X-HOST: 127.0.0.1'
469 - Remove the next member from the client_state struct. Only the main
470 thread needs access to all client states so give it its own struct.
471 - Garbage-collect request_contains_null_bytes().
472 - Ditch redundant code in unload_configfile().
473 - Ditch LogGetURLUnderCursor() which doesn't seem to be used anywhere.
474 - In write_socket(), remove the write-only variable write_len in
475 an ifdef __OS2__ block. Spotted by cppcheck.
476 - In connect_to(), don't declare the variable 'flags' on OS/2 where
477 it isn't used. Spotted by cppcheck.
478 - Limit the scope of various variables. Spotted by cppcheck.
479 - In add_to_iob(), turn an interestingly looking for loop into a
481 - Code cleanup in preparation for external filters.
482 - In listen_loop(), mention the socket on which we accepted the
483 connection, not just the source IP address.
484 - In write_socket(), also log the socket we're writing to.
485 - In log_error(), assert that escaped characters get logged
486 completely or not at all.
487 - In log_error(), assert that ival and sval have reasonable values.
488 There's no reason not to abort() if they don't.
489 - Remove an incorrect cgi_error_unknown() call in a
490 cannot-happen-situation in send_crunch_response().
491 - Clean up white-space in http_response definition and
492 move the crunch_reason to the beginning.
493 - Turn http_response.reason into an enum and rename it
494 to http_response.crunch_reason.
495 - Silence a 'gcc (Debian 4.3.2-1.1) 4.3.2' warning on i686 GNU/Linux.
496 - Fix white-space in a log message in remove_chunked_transfer_coding().
497 While at it, add a note that the message doesn't seem to
498 be entirely correct and should be improved later on.
500 - GNUmakefile improvements:
501 - Use $(SSH) instead of ssh, so one only needs to specify a username once.
502 - Removed references to the action feedback thingy that hasn't been
504 - Consistently use shell.sourceforge.net instead of shell.sf.net so
505 one doesn't need to check server fingerprints twice.
506 - Removed GNUisms in the webserver and webactions targets so they
507 work with standard tar.
509 *** Version 3.0.16 Stable ***
511 - Added the config file option handle-as-empty-doc-returns-ok to
512 work around Firefox bug #492459, which causes Firefox to hang
513 if JavaScripts are blocked in certain situations. The option is
514 enabled in the default config file.
515 - Added the config file option default-server-timeout to control the
516 assumed default server timeout. Since Privoxy no longer returns
517 an error message for connection resets on reused client connections,
518 assuming larger server timeout values appears to actually work
519 pretty well as long as connections aren't shared.
520 - Added optional support for FreeBSD's accf_http(9). Use the
521 configure option --enable-accept-filter to enable it.
522 - Added fancier Privoxy icons for win32. Contributed by Jeff H.
523 - In daemon mode, fd 0, 1 and 2 are bound to /dev/null.
524 - Resolve localhost using whatever address family the operating
525 system feels like. Previous betas would try to use IPv4 as this
526 is what most users expect, but this didn't work reliably on
528 - In the action lists on CGI pages, actions and their parameters are
529 no longer separated with a space. The action file parser doesn't
530 actually allow this and will throw an invalid syntax error if actions
531 and parameters in the action files are separated. Not adding the
532 spaces means copy and pasting CGI output into the action files works.
533 - The default keep-alive timeout has been reduced to 5 seconds to work
534 around hangs in clients that treat the proxy like any other host and
535 stop allowing any new connections if the "maximum number of
536 connections per host" is reached.
537 - Several webbug URLs that look like they are leading to images are now
538 blocked as image instead of empty documents. Doing the latter causes
539 WebKit-based clients to show a "missing image" icon which may mess up
541 - The no-such-domain template is used for DNS resolution
542 problems with FEATURE_IPV6_SUPPORT enabled. Previously the
543 connect-failed template was used. Reported by 'zebul666'.
544 - Accepts quoted expiration dates even though RFC 2109 10.1.2
545 doesn't seem to allow them. Reported anonymously.
546 - Don't try to forget connections if connection sharing is disabled.
547 This wasn't a real problem but caused an unnecessary log message.
548 - The still undocumented --enable-extended-host-patterns configure
549 option has a better description.
550 - Fixed an error message that would claim a write to the server
551 failed when actually writing to the client failed.
552 - Log the crunch reason before trying to write to the client.
553 The log is easier to read that way.
554 - Several log messages about client connections also mention
556 - handle-as-empty-document no longer depends on the image blocking
558 - Privoxy-Log-Parser is roughly 40% faster in highlighting mode.
559 - uagen, a Firefox User-Agent generator for Privoxy and Mozilla
560 browsers has been imported and is available in the tarball's
562 - The scripts in the tools directory treat unknown parameters
565 *** Version 3.0.15 Beta ***
567 - In case of missing server data, no error message is send to the
568 client if the request arrived on a reused connection. The client
569 is then supposed to silently retry the request without bothering
570 the user. This should significantly reduce the frequency of the
571 "No server or forwarder data received" error message many users
573 - More reliable detection of prematurely closed client sockets
574 with keep-alive enabled.
575 - FEATURE_CONNECTION_KEEP_ALIVE is decoupled from
576 FEATURE_CONNECTION_SHARING and now available on
578 - Improved handling of POST requests on reused connections.
579 Should fix problems with stalled connections after submitting
580 form data with some browser configurations.
581 - Fixed various latency calculation issues.
582 - Allows the client to pass NTLM authentication requests to a
583 forwarding proxy. This was already assumed and hinted to work
584 in 3.0.13 beta but actually didn't. Now it's confirmed to work
585 with IE, Firefox and Chrome.
586 Thanks to Francois Botha and Wan-Teh Chang
587 - Fixed a calculation problem if receiving the server headers
588 takes more than two reads, that could cause Privoxy to terminate
589 the connection prematurely. Reported by Oliver.
590 - Compiles again on platforms such as OpenBSD and systems
591 using earlier glibc version that don't support AI_ADDRCONFIG.
592 Anonymously submitted in #2872591.
593 - A bunch of MS VC project files and Suse and Redhat RPM spec
594 files have been removed as they were no longer maintained for
596 - Overly long action lines are properly rejected with a proper
597 error message. Previously they would be either rejected as
598 invalid or cause a core dump through abort().
599 - Already timed-out connections are no longer temporarily remembered.
600 They weren't reused anyway, but wasted a socket slot.
601 - len refers to the number of bytes actually read which might
602 differ from the ones received. Adjust log messages accordingly.
603 - The optional JavaScript on the CGI page uses encodeURIComponent()
604 instead of escape() which doesn't encode all characters that matter.
605 Anonymously reported in #2832722.
606 - Fix gcc45 warnings in decompress_iob().
607 - Various log message improvements.
608 - Privoxy-Regression-Test supports redirect tests.
609 - Privoxy-Log-Parser can gather some connection statistics.
611 *** Version 3.0.14 Beta ***
613 - The latency is taken into account when evaluating whether or not to
614 reuse a connection. This should significantly reduce the number of
615 connections problems several users reported.
616 - If the server doesn't specify how long the connection stays alive,
617 Privoxy errs on the safe side of caution and assumes it's only a second.
618 - The error pages for connection timeouts or missing server data use a
619 Last-Modified date in the past. Retry attempts are detected and Privoxy
620 removes the If-Modified-Since header to prevent the server from responding
621 with status code 304 in which case the client would reuse the error message.
622 - Setting keep-alive-timeout to 0 disables keep-alive support. Previously
623 Privoxy would claim to allow persistence but not reuse the connection.
624 - Pipelined requests are less likely to be mistaken for the request
625 body of the previous request. Note that Privoxy still has no real
626 pipeline support and will either serialize pipelined requests or
627 drop them in which case the client has to resent them.
628 - Fixed a crash on some Windows versions when header randomization
629 is enabled and the date couldn't be parsed.
630 - Privoxy's keep-alive timeout for the current connection is reduced
631 to the one specified in the client's Keep-Alive header.
632 - For HTTP/1.1 requests, Privoxy implies keep-alive support by not
633 setting any Connection header instead of using 'Connection: keep-alive'.
634 - If the socket isn't reusable, Privoxy doesn't temporarily waste
635 a socket slot to remember the connection.
636 - If keep-alive support is disabled but compiled in, the client's
637 Keep-Alive header is removed.
638 - Fixed a bug on mingw32 where downloading large files failed if
639 keep-alive support was enabled.
640 - Fixed a bug that (at least theoretically) could cause log
641 timestamps to be occasionally off by about a second.
642 - No Proxy-Connection header if added if there already is one.
643 - The configure script respects the $PATH variable when searching
646 *** Version 3.0.13 Beta ***
648 - Added IPv6 support. Thanks to Petr Pisar who not only provided
649 the initial patch but also helped a lot with the integration.
650 - Added client-side keep-alive support.
651 - The connection sharing code is only used if the connection-sharing
653 - The max-client-connections option has been added to restrict
654 the number of client connections below a value enforced by
655 the operating system.
656 - Fixed a regression reintroduced in 3.0.12 that could cause
657 crashes on mingw32 if header date randomization was enabled.
658 - Compressed content with extra fields couldn't be decompressed
659 and would get passed to the client unfiltered. This problem
660 has only be detected through statical analysis with clang as
661 nobody seems to be using extra fields anyway.
662 - If the server resets the Connection after sending only the headers
663 Privoxy forwards what it got to the client. Previously Privoxy
664 would deliver an error message instead.
665 - Error messages in case of connection timeouts use the right
667 - If spawning a child to handle a request fails, the client
668 gets an error message and Privoxy continues to listen for
669 new requests right away.
670 - The error messages in case of server-connection timeouts or
671 prematurely closed server connections are now template-based.
672 - If zlib support isn't compiled in, Privoxy no longer tries to
673 filter compressed content unless explicitly asked to do so.
674 - In case of connections that are denied based on ACL directives,
675 the memory used for the client IP is no longer leaked.
676 - Fixed another small memory leak if the client request times out
677 while waiting for client headers other than the request line.
678 - The client socket is kept open until the server socket has
679 been marked as unused. This should increase the chances that
680 the still-open connection will be reused for the client's next
681 request to the same destination. Note that this only matters
682 if connection-sharing is enabled.
683 - A TODO list has been added to the source tarball to give potential
684 volunteers a better idea of what the current goals are. Donations
685 are still welcome too: http://www.privoxy.org/faq/general.html#DONATE
687 *** Version 3.0.12 ***
689 - The socket-timeout option now also works on platforms whose
690 select() implementation modifies the timeout structure.
691 Previously the timeout was triggered even if the connection
692 didn't stall. Reported by cyberpatrol.
693 - The Connection: keep-alive code properly deals with files
694 larger than 2GB. Previously the connection was closed too
696 - The content length for files above 2GB is logged correctly.
697 - The user-manual directive on the show-status page links to
698 the documentation location specified with the directive,
699 not to the Privoxy website.
700 - When running in daemon mode, Privoxy doesn't log anything
701 to the console unless there are errors before the logfile
703 - The show-status page prints warnings about invalid directives
704 on the same line as the directives themselves.
705 - Fixed several justified (but harmless) compiler warnings,
706 mostly on 64 bit platforms.
707 - The mingw32 version explicitly requests the default charset
708 to prevent display problems with some fonts available on more
709 recent Windows versions. Patch by Burberry.
710 - The mingw32 version uses the Privoxy icon in the alt-tab
711 windows. Patch by Burberry.
712 - The timestamp and the thread id is omitted in the "Fatal error"
713 message box on mingw32.
714 - Fixed two related mingw32-only buffer overflows. Triggering
715 them required control over the configuration file, therefore
716 this isn't seen as a security issue.
717 - In verbose mode, or if the new option --show-skipped-tests
718 is used, Privoxy-Regression-Test logs skipped tests and the
721 *** Version 3.0.11 ***
723 - On most platforms, outgoing connections can be kept alive and
724 reused if the server supports it. Whether or not this improves
725 things depends on the connection.
726 - When dropping privileges, membership in supplementary groups
727 is given up as well. Not doing that can lead to Privoxy running
728 with more rights than necessary and violates the principle of
729 least privilege. Users of the --user option are advised to update.
730 Thanks to Matthias Drochner for reporting the problem,
731 providing the initial patch and testing the final version.
732 - Passing invalid users or groups with the --user option
733 didn't lead to program exit. Regression introduced in 3.0.7.
734 - The match all section has been moved from default.action
735 to a new file called match-all.action. As a result the
736 default.action no longer needs to be touched by the user
737 and can be safely overwritten by updates.
738 - The standard.action file has been removed. Its content
739 is now part of the default.action file.
740 - In some situations the logged content length was slightly too low.
741 - Crunched requests are logged with their own log level.
742 If you used "debug 1" in the past, you'll probably want
743 to additionally enable "debug 1024", otherwise only passed
744 requests will be logged. If you only care about crunched
745 requests, simply replace "debug 1" with "debug 1024".
746 - The crunch reason has been moved to the beginning of the
747 crunch message. For HTTP URLs, the protocol is logged as well.
748 - Log messages are shortened by printing the thread id on its
749 own (as opposed to putting it inside the string "Privoxy()").
750 - The config option socket-timeout has been added to control
751 the time Privoxy waits for data to arrive on a socket.
752 - Support for remote toggling is controlled by the configure
753 option --disable-toggle only. In previous versions it also
754 depended on the action editor and thus configuring with the
755 --disable-editor option would disable remote toggling support
757 - Requests with invalid HTTP versions are rejected.
758 - The template symbol @date@ can be used to include a date(1)-like
759 time string. Initial patch submitted by Endre Szabo.
760 - Responses from shoutcast servers are accepted again.
761 Problem reported and fix suggested by Stefan.
762 - The hide-forwarded-for-headers action has been replaced with
763 the change-x-forwarded-for{} action which can also be used to
764 add X-Forwarded-For headers. The latter functionality already
765 existed in Privoxy versions prior to 3.0.7 but has been removed
766 as it was often used unintentionally (by not using the
767 hide-forwarded-for-headers action).
768 - A "clear log" view option was added to the mingw32 version
769 to clear out all of the lines in the Privoxy log window.
770 Based on a patch submitted by T Ford.
771 - The mingw32 version uses "critical sections" now, which prevents
772 log message corruption under load. As a side effect, the
773 "no thread-safe PRNG" warning could be removed as well.
774 - The mingw32 version's task bar icon is crossed out and
775 the color changed to gray if Privoxy is toggled off.
777 *** Version 3.0.10 ***
779 - Ordinary configuration file changes no longer cause program
780 termination on OS/2 if the name of the logfile hasn't been
781 changed as well. This regression probably crept in with the
782 logging improvements in 3.0.7. Reported by Maynard.
783 - The img-reorder filter is less likely to mess up JavaScript code in
784 img tags. Problem and solution reported by Glenn Washburn in #2014552.
785 - The source tar ball now includes Privoxy-Log-Parser,
786 a syntax-highlighter for Privoxy logs. For fancy screenshots see:
787 http://www.fabiankeil.de/sourcecode/privoxy-log-parser/
788 Documentation is available through perldoc(1).
790 *** Version 3.0.9 Beta ***
792 - Added SOCKS5 support (with address resolution done by
793 the SOCKS5 server). Patch provided by Eric M. Hopper.
794 - The "blocked" CGI pages include a block reason that was
795 provided as argument to the last-applying block action.
796 - If enable-edit-actions is disabled (the default since 3.0.7 beta)
797 the show-status page hides the edit buttons and explains why.
798 Previously the user would get the "this feature has been disabled"
799 message after using the edit button.
800 - Forbidden CONNECT requests are treated like blocks by default.
801 The now-pointless treat-forbidden-connects-like-blocks action
803 - Not enabling limit-connect now allows CONNECT requests to all ports.
804 In previous versions it would only allow CONNECT requests to port 443.
805 Use +limit-connect{443} if you think you need the old default behaviour.
806 - The CGI editor gets turned off after three edit requests with invalid
807 file modification timestamps. This makes life harder for attackers
808 who can leverage browser bugs to send fake Referers and intend to
809 brute-force edit URLs.
810 - Action settings for multiple patterns in the same section are
811 shared in memory. As a result these sections take up less space
812 (and are loaded slightly faster). Problem reported by Franz Schwartau.
813 - Linear white space in HTTP headers will be normalized to single
814 spaces before parsing the header's content, headers split across
815 multiple lines get merged first. This should prevent problems like:
816 * letting the session-cookies-only action slip
817 some Cookies through unmodified,
818 * only suppressing the first line of a header,
819 thus creating an invalid one, and
820 * to incorrectly block headers with valid timestamps
821 that weren't properly recognized.
822 Headers that could trigger these problems are unlikely to appear
823 in "normal" web traffic, but could be intentionally generated to
824 fool some of Privoxy's header parsers.
825 - Host information is gathered outside the main thread so it's less
826 likely to delay other incoming connections if the host is misconfigured.
827 - New config option "hostname" to use a hostname other than
828 the one returned by the operating system. Useful to speed-up responses
829 for CGI requests on misconfigured systems. Requested by Max Khon.
830 - The CGI editor supports the "disable all filters of this type"
831 directives "-client-header-filter", "-server-header-filter",
832 "-client-header-tagger" and "-server-header-tagger".
833 - Fixed false-positives with the link-by-url filter and URLs that
834 contain the pattern "/jump/".
835 - The less-download-windows filter no longer messes
836 "Content-Type: application/x-shockwave-flash" headers up.
837 - In the show-url-info page's "Final results" section active and
838 inactive actions are listed separately. Patch provided by Lee.
839 - The GNUmakefile supports the DESTDIR variable. Patch for
840 the install target submitted by Radoslaw Zielinski.
841 - Embedding the content of configuration files in the show-status
842 page is significantly faster now. For a largish action file (1 MB)
843 a speedup of about 2450 times has been measured. This is mostly
844 interesting if you are using large action files or regularly use
845 Privoxy-Regression-Test while running Privoxy through Valgrind,
846 for stock configuration files it doesn't really matter.
847 - If zlib support is unavailable and there are content
848 filters active but the prevent-compression action is disabled,
849 the show-url-info page includes a warning that compression
850 might prevent filtering.
851 - The show-url-info page provides an OpenSearch Description that
852 allows to access the page through browser search plugins.
853 - Custom client-header filters that rewrite the request line
854 incorrectly no longer cause Privoxy to crash. Reported by din_a4.
855 - The obsolete kill-popups action has been removed as the
856 PCRS-based popup filters can do the same and are slightly
858 - The inspect-jpegs action has been removed.
859 - The send-wafer and send-vanilla-wafer actions have been removed.
860 They weren't particular useful and their behaviour could be emulated
861 with add-header anyway.
862 - Privoxy-Regression-Test has been significantly improved.
863 - Most sections in the default.action file contain tests for
864 Privoxy-Regression-Test to verify that they are working as intended.
865 - Parts of Privoxy have been refactored to increase maintainability.
866 - Building with zlib (if available) is done by default.
868 *** Version 3.0.8 ***
870 - Fixed a small memory leak when listen-address only specifies the port.
871 - The source tar balls now include Privoxy-Regression-Test which
872 (upon other things) can be used to automatically detect some
873 packaging problems. Packagers are welcome to give it a try.
874 - Reverted a change in 3.0.7 that caused path patterns to be checked
875 even if the host pattern match already failed. While this doesn't
876 noticeable affect the performance, it makes it less likely to run
877 out of stack space with overly-complex path patterns the user might
879 - Updated the msn, yahoo and google filters to work as advertised again.
880 - The warning message shown by the show-status CGI page is easier to
881 understand. Previously it wasn't clear that the error message
882 is shown below the invalid directive. (Reported by Lee)
883 - When regenerating Content-Disposition headers the more common
884 spelling is used for the name. Previously it was written without caps.
885 - Less confusing log message if the content type isn't overwritten
886 because force-text-type wasn't used but the old type doesn't look
887 like content that would be filtered normally.
888 - Better log messages if the user tries to execute filters that
890 - Treat the non-standard Request-Range headers like standard range
891 headers and suppress them if content filtering is enabled.
892 - Prevent the log messages for CONNECT requests to unacceptable
893 ports from printing the limit-connect argument as [null] if
894 limit-connect hasn't been explicitly enabled.
895 - Don't disable the mingw32 log window if the logfile directive
896 isn't used. While it was an intentional change in 3.0.7 at least
897 one user perceived it as a regression and the same effect can
898 be achieved by disabling all debug directives.
899 - Fixed two minor problems related to the win32 build process: a css
900 file was not being in the installer and the trustfile comment in the
901 config.txt referenced a nonexisting file
902 - Minor documentation fixes.
904 *** Version 3.0.7 Beta ***
906 - Added zlib support to filter content with gzip and deflate
907 encoding. (Patch provided by Wil Mahan)
908 - Dedicated filters and actions are used for header filtering.
909 "filter-client-headers" and "filter-client-headers" are no longer
910 supported, use server-header-filter{} and client-header-filter{}
912 - Tags can be used to change actions based on HTTP headers.
913 - New server-header filter: less-download-windows.
914 - New client-header taggers: css-requests, image-requests,
915 client-ip-address, http-method, allow-post, complete-url,
916 user-agent and privoxy-control.
917 - New server-header taggers: content-type and privoxy-control.
918 - The forward-override{} action allows to change the forwarding
919 settings through the action files, for example based on client
920 headers like the User-Agent, or the request origin.
921 - Socks errors are no longer handled by the CGI page for
922 DNS resolution failures.
923 - CGI pages use favicons to signal whether they are error
924 or control pages. This is useful if you rely heavily on
926 - The show-url-info CGI page shows the forwarding settings.
927 - "Crunch!" log messages (used when Privoxy answers requests
928 by itself) now also contain the reason.
929 - Allow to rewrite the request destination behind the client's back.
930 - Fix socks requests on big-endian platforms. Patch provided by Song Weijia.
931 - Fixes possible deadlocks and crashes on OpenBSD.
932 Patch provided by Ralf Horstmann.
933 - The CGI action editor allows to edit actionfiles with previously
934 forbidden characters like dots.
935 - New trust entries are saved with a comment that contains the
936 trusted referring URL (Suggested by Daniel Griscom).
937 - Filter descriptions are HTML encoded automatically.
938 - New config option "split-large-forms" to work
939 around a browser bug that caused IE6 and IE7 to ignore
940 the Submit button on the edit-actions-for-url CGI page.
941 - New config option "allow-cgi-request-crunching" to allow
942 requests for Privoxy's CGI pages to be blocked, redirected
943 or (un)trusted like ordinary requests.
944 - Empty filter files no longer interrupt the filtering process
945 prematurely and are correctly listed on the show-status CGI page.
946 - New config option "accept-intercepted-requests" to combine
947 Privoxy with any packet filter to build an intercepting proxy
948 for HTTP/1.1 requests (and for HTTP/1.0 requests with Host header set).
949 - fast-redirects{} catch redirects to https URLs as well.
950 - redirect{s@foo@bar@} can be used to redirect to a rewritten
951 version of the original URL.
952 - Trap unsupported gopher proxy requests.
953 - Fixed a bug in the User Manual delivery on Windows
954 (mingw32 only). Images now show up correctly and HTML
955 pages are no longer padded with garbage data.
956 - Fixed several minor memory leaks, most of them discovered with Valgrind.
957 - Only unlink the pidfile if it's actually used.
958 - Retries after connection problems with forced requests
959 aren't blocked again.
960 - On Unix SIGABRT causes a core dump as expected and is no
961 longer treated as normal shutdown signal.
962 - The "access denied" CGI page is more descriptive and
963 allows retries to circumvent the referrer check.
964 - Updated PCRS to handle unexpected PCRE errors properly.
965 Fixed crashes that could occur if Privoxy was build
966 with external PCRE versions newer than Privoxy's internal
967 one. (Reported by Chung-chieh Shan)
968 - Fixed crashes with null bytes in PCRS replacement strings
969 (Patch provided by Felix Gröbert).
970 - Fixed crashes with header time randomization on mingw32.
971 - The CGI style sheet is no longer delivered if the referring
972 page isn't a Privoxy CGI page. This prevents a JavaScript-based
973 Privoxy detection "attack". Note that detecting Privoxy is
974 still possible through other ways and Privoxy was never intended
975 to be invisible anyway.
976 - Added support for AmigaOS 4, fixed build for AmigaOS 3.x.
977 - The show-url-info CGI page displays a warning if Privoxy
978 is currently toggled off.
979 - The show-status CGI page suppresses the edit button
980 for action files if Privoxy has no write access.
981 - Most CGI error pages react properly to HEAD requests.
982 - Requests with RFC 3253 HTTP methods (used by Subversion)
983 are accepted. (Patch provided by Petr Kadlec)
984 - New config option "templdir" to change the location
985 of the CGI templates to make sure customized templates
987 - Better handling of "HTTP/1.1 100 Continue" responses.
988 - The background of the PNG pattern is transparent.
989 - Fixed XML syntax errors caused by banners-by-size and banners-by-url.
990 - Fixed crashes and possible action file corruptions
991 when lines containing hashes are written through the CGI editor.
992 - Supports dynamic filters which can contain variables.
993 - Supports tags to change the actions based on client or server headers.
994 - Incorrect actions are logged before program termination.
995 - The "actionsfile" syntax in the configuration file is consistent
996 with the rest of the configuration options and requires the
997 whole file name. This is an incompatible change, if you use
998 an old configuration file you might have to append ".action"
999 to your "actionsfile" directives.
1000 - With the configuration file option "enforce-blocks" the
1001 "go there anyway" mechanism can be disabled without recompiling
1003 - More precise error messages in case of incorrect acl syntax.
1004 - Logs a warning if filtering is enabled but impossible due
1005 to lack of zlib support or use of the prevent-compression action.
1006 - Less noisy handling of Cookie:" and "Connection:" headers.
1007 - Improved error messages in case of connection problems.
1008 - Fix a command-line-parsing bug that was introduced before 3.0.5
1009 beta and caused Privoxy to treat the last argument as configuration
1010 file if no configuration file was specified.
1011 - Treat unknown command line options as fatal errors instead
1012 of silently ignoring them.
1013 - Use string functions with length checks more often.
1014 - Don't log CONNECT requests twice.
1015 - Allow to log the source address for ACL-related connection drops.
1016 - Don't ignore applying filters if the server didn't
1017 specify a Content-Type. Bug reported by Amuro Namie.
1018 - Rejected CONNECT requests are logged with log level info
1019 (enabled by default) and the reason for the block.
1020 - New command line option "--pre-chroot-nslookup hostname" to
1021 intialize the resolver library before chroot'ing. On some systems this
1022 reduces the number of files that must be copied into the chroot tree.
1023 (Patch provided by Stephen Gildea)
1024 - Fix a long-standing memory corruption bug that could cause
1025 Privoxy to overwrite a single byte in memory it didn't explicitly
1026 allocate (but that probably was allocated anyway due to bucket size).
1027 - Send template-based CGI pages as HTTP/1.1 unless the client
1029 - Let the first line in connection established responses
1030 end in \r\n as required by RFC1945. Reported by Bert van Leeuwen.
1031 - If no log file has been specified, disable logging instead of logging
1033 - Don't block stderr when in daemon mode.
1034 - Ignore missing zero-chunks when filtering chunk-encoded content.
1035 Earlier Privoxy versions would buffer and then forward the content
1036 unmodified which caused some browsers to simply show empty pages.
1037 - Fix double free in cgi_edit_actions_list(). Reported by Venustech AD-LAB.
1038 - The code to add X-Forwarded-For headers when the hide-forwarded-for-headers
1039 action isn't being used has been removed.
1040 - Fixed trustfile feature which previously didn't work without FEATURE_TOGGLE.
1042 - Minor code clean-ups, filter and action file updates.
1043 (Some of them reported by Davide Alberani, Markus Elfring,
1044 Stefan Huehner and Adam Piggott)
1046 *** Version 3.0.6 ***
1048 - New content filters: no-ping, google, msn, yahoo and blogspot.
1049 - New header filters: x-httpd-php-to-html, html-to-xml, xml-to-html
1050 and hide-tor-exit-notation.
1051 - The special header "X-Filter: No" now disables header filtering as well.
1052 - Improved the filters img-reorder, js-annoyances, webbugs,
1053 banners-by-size, banners-by-link and ie-exploits to make them
1054 less likely to break anything.
1055 - Removed outdated URL patterns in default.action and added new ones.
1056 - Added redirection from http://p.p/user-manual to http://p.p/user-manual/
1057 - Changed webinterface default values for hide-user-agent, hide-referrer
1058 and set-image-blocker.

1065 http://www.fabiankeil.de/sourcecode/privoxy/. Includes the
1066 following new or significantly improved actions (among many
1067 other improvements):
1069 content-type-overwrite{}
1070 crunch-client-header{string}
1071 crunch-if-none-match
1072 crunch-server-header{string}
1073 fast-redirects{check-decoded-url}
1074 filter-client-headers
1075 filter-server-headers
1077 handle-as-empty-document
1078 hide-accept-language{}
1079 hide-content-disposition{}
1080 hide-if-modified-since
1081 hide-referrer{conditional-block}
1082 overwrite-last-modified{}
1084 treat-forbidden-connects-like-blocks

1109 - Fixed yet another two memory leaks. Process growth seems stopped now.
1110 - Further tightened security against malicious toggle-off links.
1111 - Excluded text/plain MIME types from filtering. This fixes a
1112 couple of client-crashing, download corruption and
1113 Privoxy performance issues, whose root cause lies in
1114 web servers labelling content of unknown type as text/plain.
1115 - Assorted fixes for POSIX compliance, signal handling, graceful
1116 termination, compiler warnings, OSX support, Win32 systray,
1117 error logging, hostname wildcards, correct detection of NetBSD.
1118 - Workarounds for client (iTunes etc) and server (PHP < 4.2.3) bugs

1136 html-annoyances, content-cookies and fun filters
1137 - Replaced filter "popups" by choice between two modes:
1138 - "unsolicited-popups" tries to catch only the unsolicited ones
1139 - "all-popups" tries to kill them all (as before)
1140 - New filter "tiny-textforms" Help those tiny or hard-wrap textareas.
1141 - New filter "jumping-windows" that prevents windows from resizing
1142 and moving themselves
1143 - New filter "demoronizer" which fixes MS's abuse of std charsets
1144 (common cases anyway).
1145 - Replaced "nimda" with more general "ie-exploits" filter in which
1146 all filters for exploits shall be collected
1147 - Improved cookie logging
1148 - Rewrote make install target. Added uninstall and install-strip
1150 - Fixed a potential (application-level, NOT OS-level!) security
1151 problem involving remote toggling and action file manipulation
1152 by mailicious websites.
1153 - Added ability to chroot (thanks to Sviatoslav Sviridov)

1202 - Various other minor fixes.
1204 *** Version 2.9.13 Beta ***
1206 - *NEWS*: The project has been renamed to Privoxy! The new name is
1207 reflected throughout (file locations, etc).
1208 - ijb.action is now default.action. re_filterfile is now
1210 - http://i.j.b/ is now http://p.p/

1239 - Fixes for actions cgi editor, make sure we have right file.
1240 - A --pidfile command line option now, in addition to --help,
1241 --version, --no-daemon, --user and configfile. --no-daemon replaces
1242 the former -d option and _DEBUG define. --user will drop privileges
1243 to the specified user.

1279 - Start a ChangeLog :)
1283 *** Version 2.9.3 pre-Alpha Changes ***
1285 - Amiga support (completely untested by me - I don't have an Amiga)
1286 - "tinygif 3" support (redirects blocked images to a specified URL, so
1287 the browser doesn't have to load and cache many copies of the same
1289 - one case where there were both local and global "referrer" variables
1290 (yuck!) clarified by renaming the local one to "refer".
1291 - Fixed some places where close() was used instead of close_socket().
1292 Thanks to Jörg Strohmayer (joergs at users.sourceforge.net) for these.
1293 - Temporary hack to get FORCE_LOAD to work with IE. I just lowercased the
1294 FORCE_LOAD_PREFIX. Needs fixing properly.
1295 - Most URLs hardcoded into Junkbuster were changed to go through a script
1296 e.g. http://ijbswa.sourceforge.net/redirect.php?v=2.9.3&to=faq
1297 The only other URLs left are the GNU GPL:
1298 http://www.fsf.org/copyleft/gpl.html
1300 http://ijbswa.sourceforge.net/
1301 ... and various URLs which will be intercepted by Junkbuster anyway.
1302 TODO: Still need to do something with the URLs in Junkbuster Corp's
1303 copyright/trademark notice on the bottom of the show-proxy-args page.
1304 - PCRE or GNU Regex is now a #define option.
1307 *** Version 2.9.2 pre-Alpha Changes ***
1309 - Andreas applied the latest version of the FORCE patch.
1312 *** Version 2.9.1 pre-Alpha Changes ***
1314 - in parsers.c, fixed two #ifdef FORCE to #ifdef FORCE_LOAD
1315 (BTW: I think FORCE is precise enough, since loading remote
1316 data is the whole purpose of a proxy..)
1317 - Set the FORCE_PREFIX (back) to 'IJB-FORCE-LOAD-'. While 'noijb.'
1318 is more elegant and looks like a hostname in the URL, it doesn't
1319 make clear to the inexperienced user that the proxy is bypassed. It
1320 also has a higher name collision risk.
1321 - Filled in the function header templates for my functions in
1322 parsers.c (again). They obviously got lost in our current
1324 - Cut the credit for the §-referrer-option from the config file,
1325 that Stefan had placed there.
1326 - Improved the re_filterfile
1329 *** Version 2.9.0 pre-Alpha Changes ***
1331 - Now use PCRE, not GNU REGEX. I have not yet had chance to check the
1332 syntax of the block/image/cookie file to ensure that they match what
1333 is expected - however they seem to work.
1334 - Replaced "configure" script with one generated by "autoconf". Also
1335 use a header "config.h" (was ijbconfig.h in my previous release) for
1336 the #defines. "config.h" is now generated with "autoheader" from
1337 "acconfig.h" and "configure.in". (Note that to install you do not
1338 need autoconf or autoheader - just run "./configure".)
1339 To see command-line options, run "./configure --help".
1340 This is my first ever autoconf script, so it has some rough edges
1341 (how PCRE is handled is the roughest).
1342 - Error logging code replaced with new module errlog.c, based on the
1343 one from JunkbusterMT (but with the threading code removed).
1344 - Most of Rodney's 0.21 and 0.21A patches applied. (Marked *). I did not
1345 apply all of these, since I had already independently done conditional
1346 popup file, conditional image file, and integration of popup code.
1347 - ACL, Jar and trust files conditionally compiled.
1348 - New source file headers.
1349 - Various cosmetic changes. (But I have not consistently ordered the
1350 config files - I think that's worthwhile, but it's 1am and I want to
1352 - RCS tags on .h files.
1353 - RCS tags are const char[] rather than const char *. (Saves 4 bytes
1355 - VC++ project files renamed to vc_junkbuster.*.
1356 - show-proxy-args now shows status of all conditionals, not just REGEX
1357 - Various functions moved around. Most notably all the system-specific
1358 sockets code which was spread between jcc.c, bind.c, and connect.c,
1359 has been moved to "jbsockets.c". The non-system-specific code from
1360 connect.c and socks4.c has been movet to "gateway.c". Also, the
1361 config file loader and the global variables it writes to have been
1362 moved to "loadcfg.c". (Maybe this should go into loaders.c?)
1363 And candidate for the "worst filename ever" award is "miscutil.c",
1364 which contains, well, miscellaneous utility functions like zalloc.
1365 (Suggestions for a better name for this file are welcome!)
1366 - Loaders now use a common function to read a line and skip comments,
1367 and this function also stores the proxy_args.
1368 - Added ./junkbuster --help (Not for Win32 GUI)
1369 - Added ./junkbuster --version (Not for Win32 GUI)
1370 - Win32 resources are now all marked as "U.S. English", rather than
1371 being a mix of "U.S. English", "U.K. English" and "Irish English".
1372 - Version number changes to 2.9.0
