4 *** Version 3.0.18 Stable ***
7 - If the redirect URL contains characters RFC 3986 doesn't permit,
8 they are (re)encoded. Not doing this makes Privoxy versions from
9 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 extenstions 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.
190 - Action file improvements:
191 - Moved the site-specific block pattern section below the one for the
192 generic patterns so for requests that are matched in both, the block
193 reason for the domain is shown which is usually more useful than showing
194 the one for the generic pattern.
195 - Remove -prevent-compression from the fragile alias It's no longer
196 used anywhere by default and isn't known to break stuff anyway.
197 - Add a (disabled) section to block various Facebook tracking URLs
198 Reported by Dan Stahlke in #3421764.
199 - Add a (disabled) section to rewrite and redirect click-tracking
200 URLs used on news.google.com
201 Reported by Dan Stahlke in #3421755.
202 - Unblock linuxcounter.net/
203 Reported by Dan Stahlke in #3422612.
204 - Block 'www91.intel.com/' which is used by Omniture.
205 Reported by Adam Piggott in #3167370.
206 - Disable the handle-as-empty-doc-returns-ok option and mark it as deprecated.
207 Reminded by tceverling in #2790091.
208 - Add ".ivwbox.de/" to the "Cross-site user tracking" section.
209 Reported by Nettozahler in #3172525.
210 - Unblock and fast-redirect ".awin1.com/.*=http://"
211 Reported by Adam Piggott in #3170921.
212 - Block "b.collective-media.net/".
213 - Widen the Debian popcon exception to "qa.debian.org/popcon".
214 Seen in Debian's 05_default_action.dpatch by Roland Rosenfeld.
215 - Block ".gemius.pl/" which only seems to be used for user tracking.
216 Reported by johnd16 in #3002731. Additional input from Lee and movax.
217 - Disable banners-by-size filters for '.thinkgeek.com/'
218 The filter only seems to catch pictures of the inventory.
219 - Block requests for 'go.idmnet.bbelements.com/please/showit/'
220 Reported by kacperdominik in #3372959.
221 - Unblock adainitiative.org/
222 - Add a fast-redirects exception for '.googleusercontent.com/.*=cache'
223 - Add a fast-redirects exception for webcache.googleusercontent.com/
224 - Unblock http://adassier.wordpress.com/ and http://adassier.files.wordpress.com/
226 - Filter file improvements:
227 - Let the yahoo filter hide '.ads'
228 - Let the msn filter hide overlay ads for Facebook 'likes' in search
229 results and elements with the id 's_notf_div'. They only seem to be
230 used to advertise site 'enhancements'.
231 - Let the js-events filter additionally disarm setInterval()
232 Suggested by dg1727 in #3423775.
234 - Documentation improvements:
235 - Clarify the effect of compiling Privoxy with zlib support
236 Suggested by dg1727 in #3423782.
237 - Point out that the SourceForge messaging system works like a black
238 hole and should thus not be used to contact individual developers.
239 - Mention some of the problems one can experience when not explicitly
240 configuring an IP addresses as listen address.
241 - Explicitly mention that hostnames can be used instead of IP addresses
242 for the listen-address, that only the first address returned will be
243 used and what happens if the address is invalid.
244 Requested by Calestyo in #3302213.
246 - Log message improvements:
247 - If only the server connection is kept alive, do not pretent to
248 wait for a new client request.
249 - Remove a superfluos log message in forget_connection()
250 - In chat(), properly report missing server responses as such
251 instead of calling them empty
252 - In forwarded_connect(), fix a log message nobody should ever see
253 - Fix a log message in socks5_connect(), a failed write operation
254 was logged as failed read operation
255 - Let load_one_actions_file() properly complain about a missing
256 '{' at the beginning of the file
257 Simply stating that a line is invalid isn't particularly helpful.
258 - Do not claim to listen on a socket until Privoxy actually does.
259 Patch submitted by Petr Pisar #3354485
260 - Prevent a duplicated LOG_LEVEL_CLF message when sending out
261 the "no-server-data" response
262 - Also log the client socket when dropping a connection.
263 - Include the destination host in the 'Request ... marked for
264 blocking. limit-connect{...} doesn't allow CONNECT ...' message
265 Patch submitted by Saperski in #3296250.
266 - Prevent a duplicated log message if none of the resolved IP
267 addresses were reachable
268 - In connect_to(), do not pretend to retry if forwarded-connect-retries
270 - When a specified user or group can't be found, put the name in
271 single-quotes when logging it.
272 - In rfc2553_connect_to(), explain getnameinfo() errors better.
273 - Remove a useless log message in chat()
274 - When retrying to connect, also log the maximum number of connection
276 - Rephrase a log message in compile_dynamic_pcrs_job_list().
277 Divide the error code and its meaning with a colon. Call the pcrs
278 job dynamic and not the filter. Filters may contain dynamic and
279 non-dynamic pcrs jobs at the same time. Only mention the name of
280 the filter or tagger, but don't claim it's a filter when it could
282 - In a fatal error message in load_one_actions_file(), cover both
283 URL and TAG patterns.
284 - In pcrs_strerror(), properly report unknown positive error code
285 values as such. Previously they were handled like 0 (no error).
286 - In compile_dynamic_pcrs_job_list(), also log the actual error code as
287 pcrs_strerror() doesn't handle all errors reported by pcre
288 - Don't bother trying to continue chatting if the client didn't ask for it.
289 Reduces log noise a bit.
290 - Make two fatal error message in load_one_actions_file() more descriptive
291 - In cgi_send_user_manual(), log when rejecting a file name due to '/' or '..'
292 - In load_file(), log a message if opening a file failed
293 The CGI error message alone isn't too helpful.
294 - In connection_destination_matches(), improve two log messages
295 to help understand why the destinations don't match.
296 - Rephrase a log message in serve(). Client request arrival
297 should be differentiated from closed client connections now.
298 - In serve(), log if a client connection isn't reused due to a
299 configuration file change.
300 - Let mark_server_socket_tainted() always mark the server socket tainted,
301 just don't talk about it in cases where it has no effect. It doesn't change
302 Privoxy's behaviour, but makes understanding the log file easier.
305 - Added a --disable-ipv6-support switch for platforms where support
306 is detected but doesn't actually work.
307 - Do not check for the existence of strerror() and memmove() twice
308 - Remove a useless test for setpgrp(2). Privoxy doesn't need it and
309 it can cause problems when cross-compiling.
310 - Rename the --disable-acl-files switch to --disable-acl-support.
311 Since about 2001, ACL directives are specified in the standard
313 - Update the URL of the 'Removing outdated PCRE version after the
314 next stable release' posting. The old URL stopped working after
315 one of SF's recent site "optimizations". Reported by Han Liu.
317 - Privoxy-Regression-Test:
318 - Added --shuffle-tests option to increase the chances of detection race conditions.
319 - Added a --local-test-file option that allows to use Privoxy-Regression-Test without Privoxy
320 - Added tests for missing socks4 and socks4a forwarders
321 - The --privoxy-address option now works with IPv6 addresses containing brackets, too
322 - Perform limited sanity checks for parameters that are supposed to have numerical values.
323 - Added a --sleep-time option to specify a number of seconds to
324 sleep between tests, defaults to 0.
325 - Disable the range-requests tagger for tests that break if it's enabled
326 - Log messages use the ISO 8601 date format %Y-%m-%d.
327 - Fix spelling in two error messages.
328 - In the --help output, include a list of supported tests and their default levels.
329 - Adjust the tests to properly deal with FEATURE_TOGGLE being disabled.
331 - Privoxy-Log-Parser:
332 - Perform limited sanity checks for command line parameters that
333 are supposed to have numerical values.
334 - Implement a --unbreak-lines-only option to try to revert MUA breakage.
335 - Accept and highlight: Added header: Content-Encoding: deflate
336 - Accept and highlight: Compressed content from 29258 to 8630 bytes.
337 - Accept and highlight: Client request arrived in time on socket 21.
338 - Highlight: Didn't receive data in time: a.fsdn.com:443
339 - Accept log messages with ISO 8601 time stamps, too
342 - Bump generated Firefox version to 8.0
343 - Only randomize the release date if the new --randomize-release-date
344 option is enabled. Firefox versions after 4 use a fixed date string
348 *** Version 3.0.17 Stable ***
350 - Fixed last-chunk-detection for responses where the body was small
351 enough to be read with the headers, causing Privoxy to wait for the
352 end of the content until the server closed the connection or the
353 request timed out. Reported by "Karsten" in #3028326.
354 - Responses with status code 204 weren't properly detected as body-less
355 like RFC2616 mandates. Like the previous bug, this caused Privoxy to
356 wait for the end of the content until the server closed the connection
357 or the request timed out. Fixes #3022042 and #3025553, reported by a
358 user with no visible name. Most likely also fixes a bunch of other
359 AJAX-related problem reports that got closed in the past due to
360 insufficient information and lack of feedback.
361 - Fixed an ACL bug that made it impossible to build a blacklist.
362 Usually the ACL directives are used in a whitelist, which worked
363 as expected, but blacklisting is still useful for public proxies
364 where one only needs to deny known abusers access.
365 - Added LOG_LEVEL_RECEIVED to log the not-yet-parsed data read from the
366 network. This should make debugging various parsing issues a lot easier.
367 - The IPv6 code is enabled by default on Windows versions that support it.
368 Patch submitted by oCameLo in #2942729.
369 - In mingw32 versions, the user.filter file is reachable through the
370 GUI, just like default.filter is. Feature request 3040263.
371 - Added the configure option --enable-large-file-support to set a few
372 defines that are required by platforms like GNU/Linux to support files
373 larger then 2GB. Mainly interesting for users without proper logfile
375 - Logging with "debug 16" no longer stops at the first nul byte which is
376 pretty useless. Non-printable characters are replaced with their hex value
377 so the result can't span multiple lines making parsing them harder then
379 - Privoxy logs when reading an action, filter or trust file.
380 - Fixed incorrect regression test markup which caused a test in
381 3.0.16 to fail while Privoxy itself was working correctly.
382 While Privoxy accepts hide-referer, too, the action name is actually
383 hide-referrer which is also the name used one the final results page,
384 where the test expected the alias.
386 - CGI interface improvements:
387 - In finish_http_response(), continue to add the 'Connection: close'
388 header if the client connection will not be kept alive.
389 Anonymously pointed out in #2987454.
390 - Apostrophes in block messages no longer cause parse errors
391 when the blocked page is viewed with JavaScript enabled.
392 Reported by dg1727 in #3062296.
393 - Fix a bunch of anchors that used underscores instead of dashes.
394 - Allow to keep the client connection alive after crunching the previous request.
395 Already opened server connections can be kept alive, too.
396 - In cgi_show_url_info(), don't forget to prefix URLs that only contain
397 http:// or https:// in the path. Fixes #2975765 reported by Adam Piggott.
398 - Show the 404 CGI page if cgi_send_user_manual() is called while
399 local user manual delivery is disabled.
401 - Action file improvements:
402 - Enable user.filter by default. Suggested by David White in #3001830.
403 - Block .sitestat.com/. Reported by johnd16 in #3002725.
404 - Block .atemda.com/. Reported by johnd16 in #3002723.
405 - Block js.adlink.net/. Reported by johnd16 in #3002720.
406 - Block .analytics.yahoo.com/. Reported by johnd16 in #3002713.
407 - Block sb.scorecardresearch.com, too. Reported by dg1727 in #2992652.
408 - Fix problems noticed on Yahoo mail and news pages.
409 - Remove the too broad yahoo section, only keeping the
410 fast-redirects exception as discussed on ijbswa-devel@.
411 - Don't block adesklets.sourceforge.net. Reported in #2974204.
412 - Block chartbeat ping tracking. Reported in #2975895.
413 - Tag CSS and image requests with cautious and medium settings, too.
414 - Don't handle view.atdmt.com as image. It's used for click-throughs
415 so users should be able to "go there anyway".
416 Reported by Adam Piggott in #2975927.
417 - Also let the refresh-tags filter remove invalid refresh tags where
418 the 'url=' part is missing. Anonymously reported in #2986382.
419 While at it, update the description to mention the fact that only
420 refresh tags with refresh times above 9 seconds are covered.
421 - javascript needs to be blocked with +handle-as-empty-document to
422 work around Firefox bug 492459. So move .js blockers from
423 +block{Might be a web-bug.} -handle-as-empty-document to
424 +block{Might be a web-bug.} +handle-as-empty-document.
425 - ijbswa-Feature Requests-3006719 - Block 160x578 Banners.
426 - Block another omniture tracking domain.
427 - Added a range-requests tagger.
428 - Added two sections to get Flickr's Ajax interface working with
429 default pre-settings. If you change the configuration to block
430 cookies by default, you'll need additional exceptions.
431 Reported by Mathias Homann in #3101419 and by Patrick on ijbswa-users@.
433 - Documentation improvements:
434 - Explicitly mention how to match all URLs.
435 - Consistently recommend socks5 in the Tor FAQ entry and mention
436 its advantage compared to socks4a. Reported by David in #2960129.
437 - Slightly improve the explanation of why filtering may appear
439 - Grammar fixes for the ACL section.
440 - Fixed a link to the 'intercepting' entry and add another one.
441 - Rename the 'Other' section to 'Mailing Lists' and reword it
442 to make it clear that nobody is forced to use the trackers
443 - Note that 'anonymously' posting on the trackers may not always
445 - Suggest to enable debug 32768 when suspecting parsing problems.
447 - Privoxy-Log-Parser improvements:
448 - Gather statistics for ressources, methods, and HTTP versions
450 - Also gather statistics for blocked and redirected requests.
451 - Provide the percentage of keep-alive offers the client accepted.
452 - Add a --url-statistics-threshold option.
453 - Add a --host-statistics-threshold option to also gather
454 statistics about how many request where made per host.
455 - Fix a bug in handle_loglevel_header() where a 'scan: ' got lost.
456 - Add a --shorten-thread-ids option to replace the thread id with
458 - Accept and ignore: Looks like we got the last chunk together
459 with the server headers. We better stop reading.
460 - Accept and ignore: Continue hack in da house.
461 - Accept and higlight: Rejecting connection from 10.0.0.2.
462 Maximum number of connections reached.
463 - Accept and highlight: Loading actions file: /usr/local/etc/privoxy/default.action
464 - Accept and highlight: Loading filter file: /usr/local/etc/privoxy/default.filter
465 - Accept and highlight: Killed all-caps Host header line: HOST: bestproxydb.com
466 - Accept and highlight: Reducing expected bytes to 0. Marking
467 the server socket tainted after throwing 4 bytes away.
468 - Accept: Merged multiple header lines to: 'X-FORWARDED-PROTO: http X-HOST: 127.0.0.1'
471 - Remove the next member from the client_state struct. Only the main
472 thread needs access to all client states so give it its own struct.
473 - Garbage-collect request_contains_null_bytes().
474 - Ditch redundant code in unload_configfile().
475 - Ditch LogGetURLUnderCursor() which doesn't seem to be used anywhere.
476 - In write_socket(), remove the write-only variable write_len in
477 an ifdef __OS2__ block. Spotted by cppcheck.
478 - In connect_to(), don't declare the variable 'flags' on OS/2 where
479 it isn't used. Spotted by cppcheck.
480 - Limit the scope of various variables. Spotted by cppcheck.
481 - In add_to_iob(), turn an interestingly looking for loop into a
483 - Code cleanup in preparation for external filters.
484 - In listen_loop(), mention the socket on which we accepted the
485 connection, not just the source IP address.
486 - In write_socket(), also log the socket we're writing to.
487 - In log_error(), assert that escaped characters get logged
488 completely or not at all.
489 - In log_error(), assert that ival and sval have reasonable values.
490 There's no reason not to abort() if they don't.
491 - Remove an incorrect cgi_error_unknown() call in a
492 cannot-happen-situation in send_crunch_response().
493 - Clean up white-space in http_response definition and
494 move the crunch_reason to the beginning.
495 - Turn http_response.reason into an enum and rename it
496 to http_response.crunch_reason.
497 - Silence a 'gcc (Debian 4.3.2-1.1) 4.3.2' warning on i686 GNU/Linux.
498 - Fix white-space in a log message in remove_chunked_transfer_coding().
499 While at it, add a note that the message doesn't seem to
500 be entirely correct and should be improved later on.
502 - GNUmakefile improvements:
503 - Use $(SSH) instead of ssh, so one only needs to specify a username once.
504 - Removed references to the action feedback thingy that hasn't been
506 - Consistently use shell.sourceforge.net instead of shell.sf.net so
507 one doesn't need to check server fingerprints twice.
508 - Removed GNUisms in the webserver and webactions targets so they
509 work with standard tar.
511 *** Version 3.0.16 Stable ***
513 - Added the config file option handle-as-empty-doc-returns-ok to
514 work around Firefox bug #492459, which causes Firefox to hang
515 if JavaScripts are blocked in certain situations. The option is
516 enabled in the default config file.
517 - Added the config file option default-server-timeout to control the
518 assumed default server timeout. Since Privoxy no longer returns
519 an error message for connection resets on reused client connections,
520 assuming larger server timeout values appears to actually work
521 pretty well as long as connections aren't shared.
522 - Added optional support for FreeBSD's accf_http(9). Use the
523 configure option --enable-accept-filter to enable it.
524 - Added fancier Privoxy icons for win32. Contributed by Jeff H.
525 - In daemon mode, fd 0, 1 and 2 are bound to /dev/null.
526 - Resolve localhost using whatever address family the operating
527 system feels like. Previous betas would try to use IPv4 as this
528 is what most users expect, but this didn't work reliably on
530 - In the action lists on CGI pages, actions and their parameters are
531 no longer separated with a space. The action file parser doesn't
532 actually allow this and will throw an invalid syntax error if actions
533 and parameters in the action files are separated. Not adding the
534 spaces means copy and pasting CGI output into the action files works.
535 - The default keep-alive timeout has been reduced to 5 seconds to work
536 around hangs in clients that treat the proxy like any other host and
537 stop allowing any new connections if the "maximum number of
538 connections per host" is reached.
539 - Several webbug URLs that look like they are leading to images are now
540 blocked as image instead of empty documents. Doing the latter causes
541 WebKit-based clients to show a "missing image" icon which may mess up
543 - The no-such-domain template is used for DNS resolution
544 problems with FEATURE_IPV6_SUPPORT enabled. Previously the
545 connect-failed template was used. Reported by 'zebul666'.
546 - Accepts quoted expiration dates even though RFC 2109 10.1.2
547 doesn't seem to allow them. Reported anonymously.
548 - Don't try to forget connections if connection sharing is disabled.
549 This wasn't a real problem but caused an unnecessary log message.
550 - The still undocumented --enable-extended-host-patterns configure
551 option has a better description.
552 - Fixed an error message that would claim a write to the server
553 failed when actually writing to the client failed.
554 - Log the crunch reason before trying to write to the client.
555 The log is easier to read that way.
556 - Several log messages about client connections also mention
558 - handle-as-empty-document no longer depends on the image blocking
560 - Privoxy-Log-Parser is roughly 40% faster in highlighting mode.
561 - uagen, a Firefox User-Agent generator for Privoxy and Mozilla
562 browsers has been imported and is available in the tarball's
564 - The scripts in the tools directory treat unknown parameters
567 *** Version 3.0.15 Beta ***
569 - In case of missing server data, no error message is send to the
570 client if the request arrived on a reused connection. The client
571 is then supposed to silently retry the request without bothering
572 the user. This should significantly reduce the frequency of the
573 "No server or forwarder data received" error message many users
575 - More reliable detection of prematurely closed client sockets
576 with keep-alive enabled.
577 - FEATURE_CONNECTION_KEEP_ALIVE is decoupled from
578 FEATURE_CONNECTION_SHARING and now available on
580 - Improved handling of POST requests on reused connections.
581 Should fix problems with stalled connections after submitting
582 form data with some browser configurations.
583 - Fixed various latency calculation issues.
584 - Allows the client to pass NTLM authentication requests to a
585 forwarding proxy. This was already assumed and hinted to work
586 in 3.0.13 beta but actually didn't. Now it's confirmed to work
587 with IE, Firefox and Chrome.
588 Thanks to Francois Botha and Wan-Teh Chang
589 - Fixed a calculation problem if receiving the server headers
590 takes more than two reads, that could cause Privoxy to terminate
591 the connection prematurely. Reported by Oliver.
592 - Compiles again on platforms such as OpenBSD and systems
593 using earlier glibc version that don't support AI_ADDRCONFIG.
594 Anonymously submitted in #2872591.
595 - A bunch of MS VC project files and Suse and Redhat RPM spec
596 files have been removed as they were no longer maintained for
598 - Overly long action lines are properly rejected with a proper
599 error message. Previously they would be either rejected as
600 invalid or cause a core dump through abort().
601 - Already timed-out connections are no longer temporarily remembered.
602 They weren't reused anyway, but wasted a socket slot.
603 - len refers to the number of bytes actually read which might
604 differ from the ones received. Adjust log messages accordingly.
605 - The optional JavaScript on the CGI page uses encodeURIComponent()
606 instead of escape() which doesn't encode all characters that matter.
607 Anonymously reported in #2832722.
608 - Fix gcc45 warnings in decompress_iob().
609 - Various log message improvements.
610 - Privoxy-Regression-Test supports redirect tests.
611 - Privoxy-Log-Parser can gather some connection statistics.
613 *** Version 3.0.14 Beta ***
615 - The latency is taken into account when evaluating whether or not to
616 reuse a connection. This should significantly reduce the number of
617 connections problems several users reported.
618 - If the server doesn't specify how long the connection stays alive,
619 Privoxy errs on the safe side of caution and assumes it's only a second.
620 - The error pages for connection timeouts or missing server data use a
621 Last-Modified date in the past. Retry attempts are detected and Privoxy
622 removes the If-Modified-Since header to prevent the server from responding
623 with status code 304 in which case the client would reuse the error message.
624 - Setting keep-alive-timeout to 0 disables keep-alive support. Previously
625 Privoxy would claim to allow persistence but not reuse the connection.
626 - Pipelined requests are less likely to be mistaken for the request
627 body of the previous request. Note that Privoxy still has no real
628 pipeline support and will either serialize pipelined requests or
629 drop them in which case the client has to resent them.
630 - Fixed a crash on some Windows versions when header randomization
631 is enabled and the date couldn't be parsed.
632 - Privoxy's keep-alive timeout for the current connection is reduced
633 to the one specified in the client's Keep-Alive header.
634 - For HTTP/1.1 requests, Privoxy implies keep-alive support by not
635 setting any Connection header instead of using 'Connection: keep-alive'.
636 - If the socket isn't reusable, Privoxy doesn't temporarily waste
637 a socket slot to remember the connection.
638 - If keep-alive support is disabled but compiled in, the client's
639 Keep-Alive header is removed.
640 - Fixed a bug on mingw32 where downloading large files failed if
641 keep-alive support was enabled.
642 - Fixed a bug that (at least theoretically) could cause log
643 timestamps to be occasionally off by about a second.
644 - No Proxy-Connection header if added if there already is one.
645 - The configure script respects the $PATH variable when searching
648 *** Version 3.0.13 Beta ***
650 - Added IPv6 support. Thanks to Petr Pisar who not only provided
651 the initial patch but also helped a lot with the integration.
652 - Added client-side keep-alive support.
653 - The connection sharing code is only used if the connection-sharing
655 - The max-client-connections option has been added to restrict
656 the number of client connections below a value enforced by
657 the operating system.
658 - Fixed a regression reintroduced in 3.0.12 that could cause
659 crashes on mingw32 if header date randomization was enabled.
660 - Compressed content with extra fields couldn't be decompressed
661 and would get passed to the client unfiltered. This problem
662 has only be detected through statical analysis with clang as
663 nobody seems to be using extra fields anyway.
664 - If the server resets the Connection after sending only the headers
665 Privoxy forwards what it got to the client. Previously Privoxy
666 would deliver an error message instead.
667 - Error messages in case of connection timeouts use the right
669 - If spawning a child to handle a request fails, the client
670 gets an error message and Privoxy continues to listen for
671 new requests right away.
672 - The error messages in case of server-connection timeouts or
673 prematurely closed server connections are now template-based.
674 - If zlib support isn't compiled in, Privoxy no longer tries to
675 filter compressed content unless explicitly asked to do so.
676 - In case of connections that are denied based on ACL directives,
677 the memory used for the client IP is no longer leaked.
678 - Fixed another small memory leak if the client request times out
679 while waiting for client headers other than the request line.
680 - The client socket is kept open until the server socket has
681 been marked as unused. This should increase the chances that
682 the still-open connection will be reused for the client's next
683 request to the same destination. Note that this only matters
684 if connection-sharing is enabled.
685 - A TODO list has been added to the source tarball to give potential
686 volunteers a better idea of what the current goals are. Donations
687 are still welcome too: http://www.privoxy.org/faq/general.html#DONATE
689 *** Version 3.0.12 ***
691 - The socket-timeout option now also works on platforms whose
692 select() implementation modifies the timeout structure.
693 Previously the timeout was triggered even if the connection
694 didn't stall. Reported by cyberpatrol.
695 - The Connection: keep-alive code properly deals with files
696 larger than 2GB. Previously the connection was closed too
698 - The content length for files above 2GB is logged correctly.
699 - The user-manual directive on the show-status page links to
700 the documentation location specified with the directive,
701 not to the Privoxy website.
702 - When running in daemon mode, Privoxy doesn't log anything
703 to the console unless there are errors before the logfile
705 - The show-status page prints warnings about invalid directives
706 on the same line as the directives themselves.
707 - Fixed several justified (but harmless) compiler warnings,
708 mostly on 64 bit platforms.
709 - The mingw32 version explicitly requests the default charset
710 to prevent display problems with some fonts available on more
711 recent Windows versions. Patch by Burberry.
712 - The mingw32 version uses the Privoxy icon in the alt-tab
713 windows. Patch by Burberry.
714 - The timestamp and the thread id is omitted in the "Fatal error"
715 message box on mingw32.
716 - Fixed two related mingw32-only buffer overflows. Triggering
717 them required control over the configuration file, therefore
718 this isn't seen as a security issue.
719 - In verbose mode, or if the new option --show-skipped-tests
720 is used, Privoxy-Regression-Test logs skipped tests and the
723 *** Version 3.0.11 ***
725 - On most platforms, outgoing connections can be kept alive and
726 reused if the server supports it. Whether or not this improves
727 things depends on the connection.
728 - When dropping privileges, membership in supplementary groups
729 is given up as well. Not doing that can lead to Privoxy running
730 with more rights than necessary and violates the principle of
731 least privilege. Users of the --user option are advised to update.
732 Thanks to Matthias Drochner for reporting the problem,
733 providing the initial patch and testing the final version.
734 - Passing invalid users or groups with the --user option
735 didn't lead to program exit. Regression introduced in 3.0.7.
736 - The match all section has been moved from default.action
737 to a new file called match-all.action. As a result the
738 default.action no longer needs to be touched by the user
739 and can be safely overwritten by updates.
740 - The standard.action file has been removed. Its content
741 is now part of the default.action file.
742 - In some situations the logged content length was slightly too low.
743 - Crunched requests are logged with their own log level.
744 If you used "debug 1" in the past, you'll probably want
745 to additionally enable "debug 1024", otherwise only passed
746 requests will be logged. If you only care about crunched
747 requests, simply replace "debug 1" with "debug 1024".
748 - The crunch reason has been moved to the beginning of the
749 crunch message. For HTTP URLs, the protocol is logged as well.
750 - Log messages are shortened by printing the thread id on its
751 own (as opposed to putting it inside the string "Privoxy()").
752 - The config option socket-timeout has been added to control
753 the time Privoxy waits for data to arrive on a socket.
754 - Support for remote toggling is controlled by the configure
755 option --disable-toggle only. In previous versions it also
756 depended on the action editor and thus configuring with the
757 --disable-editor option would disable remote toggling support
759 - Requests with invalid HTTP versions are rejected.
760 - The template symbol @date@ can be used to include a date(1)-like
761 time string. Initial patch submitted by Endre Szabo.
762 - Responses from shoutcast servers are accepted again.
763 Problem reported and fix suggested by Stefan.
764 - The hide-forwarded-for-headers action has been replaced with
765 the change-x-forwarded-for{} action which can also be used to
766 add X-Forwarded-For headers. The latter functionality already
767 existed in Privoxy versions prior to 3.0.7 but has been removed
768 as it was often used unintentionally (by not using the
769 hide-forwarded-for-headers action).
770 - A "clear log" view option was added to the mingw32 version
771 to clear out all of the lines in the Privoxy log window.
772 Based on a patch submitted by T Ford.
773 - The mingw32 version uses "critical sections" now, which prevents
774 log message corruption under load. As a side effect, the
775 "no thread-safe PRNG" warning could be removed as well.
776 - The mingw32 version's task bar icon is crossed out and
777 the color changed to gray if Privoxy is toggled off.
779 *** Version 3.0.10 ***
781 - Ordinary configuration file changes no longer cause program
782 termination on OS/2 if the name of the logfile hasn't been
783 changed as well. This regression probably crept in with the
784 logging improvements in 3.0.7. Reported by Maynard.
785 - The img-reorder filter is less likely to mess up JavaScript code in
786 img tags. Problem and solution reported by Glenn Washburn in #2014552.
787 - The source tar ball now includes Privoxy-Log-Parser,
788 a syntax-highlighter for Privoxy logs. For fancy screenshots see:
789 http://www.fabiankeil.de/sourcecode/privoxy-log-parser/
790 Documentation is available through perldoc(1).
792 *** Version 3.0.9 Beta ***
794 - Added SOCKS5 support (with address resolution done by
795 the SOCKS5 server). Patch provided by Eric M. Hopper.
796 - The "blocked" CGI pages include a block reason that was
797 provided as argument to the last-applying block action.
798 - If enable-edit-actions is disabled (the default since 3.0.7 beta)
799 the show-status page hides the edit buttons and explains why.
800 Previously the user would get the "this feature has been disabled"
801 message after using the edit button.
802 - Forbidden CONNECT requests are treated like blocks by default.
803 The now-pointless treat-forbidden-connects-like-blocks action
805 - Not enabling limit-connect now allows CONNECT requests to all ports.
806 In previous versions it would only allow CONNECT requests to port 443.
807 Use +limit-connect{443} if you think you need the old default behaviour.
808 - The CGI editor gets turned off after three edit requests with invalid
809 file modification timestamps. This makes life harder for attackers
810 who can leverage browser bugs to send fake Referers and intend to
811 brute-force edit URLs.
812 - Action settings for multiple patterns in the same section are
813 shared in memory. As a result these sections take up less space
814 (and are loaded slightly faster). Problem reported by Franz Schwartau.
815 - Linear white space in HTTP headers will be normalized to single
816 spaces before parsing the header's content, headers split across
817 multiple lines get merged first. This should prevent problems like:
818 * letting the session-cookies-only action slip
819 some Cookies through unmodified,
820 * only suppressing the first line of a header,
821 thus creating an invalid one, and
822 * to incorrectly block headers with valid timestamps
823 that weren't properly recognized.
824 Headers that could trigger these problems are unlikely to appear
825 in "normal" web traffic, but could be intentionally generated to
826 fool some of Privoxy's header parsers.
827 - Host information is gathered outside the main thread so it's less
828 likely to delay other incoming connections if the host is misconfigured.
829 - New config option "hostname" to use a hostname other than
830 the one returned by the operating system. Useful to speed-up responses
831 for CGI requests on misconfigured systems. Requested by Max Khon.
832 - The CGI editor supports the "disable all filters of this type"
833 directives "-client-header-filter", "-server-header-filter",
834 "-client-header-tagger" and "-server-header-tagger".
835 - Fixed false-positives with the link-by-url filter and URLs that
836 contain the pattern "/jump/".
837 - The less-download-windows filter no longer messes
838 "Content-Type: application/x-shockwave-flash" headers up.
839 - In the show-url-info page's "Final results" section active and
840 inactive actions are listed separately. Patch provided by Lee.
841 - The GNUmakefile supports the DESTDIR variable. Patch for
842 the install target submitted by Radoslaw Zielinski.
843 - Embedding the content of configuration files in the show-status
844 page is significantly faster now. For a largish action file (1 MB)
845 a speedup of about 2450 times has been measured. This is mostly
846 interesting if you are using large action files or regularly use
847 Privoxy-Regression-Test while running Privoxy through Valgrind,
848 for stock configuration files it doesn't really matter.
849 - If zlib support is unavailable and there are content
850 filters active but the prevent-compression action is disabled,
851 the show-url-info page includes a warning that compression
852 might prevent filtering.
853 - The show-url-info page provides an OpenSearch Description that
854 allows to access the page through browser search plugins.
855 - Custom client-header filters that rewrite the request line
856 incorrectly no longer cause Privoxy to crash. Reported by din_a4.
857 - The obsolete kill-popups action has been removed as the
858 PCRS-based popup filters can do the same and are slightly
860 - The inspect-jpegs action has been removed.
861 - The send-wafer and send-vanilla-wafer actions have been removed.
862 They weren't particular useful and their behaviour could be emulated
863 with add-header anyway.
864 - Privoxy-Regression-Test has been significantly improved.
865 - Most sections in the default.action file contain tests for
866 Privoxy-Regression-Test to verify that they are working as intended.
867 - Parts of Privoxy have been refactored to increase maintainability.
868 - Building with zlib (if available) is done by default.
870 *** Version 3.0.8 ***
872 - Fixed a small memory leak when listen-address only specifies the port.
873 - The source tar balls now include Privoxy-Regression-Test which
874 (upon other things) can be used to automatically detect some
875 packaging problems. Packagers are welcome to give it a try.
876 - Reverted a change in 3.0.7 that caused path patterns to be checked
877 even if the host pattern match already failed. While this doesn't
878 noticeable affect the performance, it makes it less likely to run
879 out of stack space with overly-complex path patterns the user might
881 - Updated the msn, yahoo and google filters to work as advertised again.
882 - The warning message shown by the show-status CGI page is easier to
883 understand. Previously it wasn't clear that the error message
884 is shown below the invalid directive. (Reported by Lee)
885 - When regenerating Content-Disposition headers the more common
886 spelling is used for the name. Previously it was written without caps.
887 - Less confusing log message if the content type isn't overwritten
888 because force-text-type wasn't used but the old type doesn't look
889 like content that would be filtered normally.
890 - Better log messages if the user tries to execute filters that
892 - Treat the non-standard Request-Range headers like standard range
893 headers and suppress them if content filtering is enabled.
894 - Prevent the log messages for CONNECT requests to unacceptable
895 ports from printing the limit-connect argument as [null] if
896 limit-connect hasn't been explicitly enabled.
897 - Don't disable the mingw32 log window if the logfile directive
898 isn't used. While it was an intentional change in 3.0.7 at least
899 one user perceived it as a regression and the same effect can
900 be achieved by disabling all debug directives.
901 - Fixed two minor problems related to the win32 build process: a css
902 file was not being in the installer and the trustfile comment in the
903 config.txt referenced a nonexisting file
904 - Minor documentation fixes.
906 *** Version 3.0.7 Beta ***
908 - Added zlib support to filter content with gzip and deflate
909 encoding. (Patch provided by Wil Mahan)
910 - Dedicated filters and actions are used for header filtering.
911 "filter-client-headers" and "filter-client-headers" are no longer
912 supported, use server-header-filter{} and client-header-filter{}
914 - Tags can be used to change actions based on HTTP headers.
915 - New server-header filter: less-download-windows.
916 - New client-header taggers: css-requests, image-requests,
917 client-ip-address, http-method, allow-post, complete-url,
918 user-agent and privoxy-control.
919 - New server-header taggers: content-type and privoxy-control.
920 - The forward-override{} action allows to change the forwarding
921 settings through the action files, for example based on client
922 headers like the User-Agent, or the request origin.
923 - Socks errors are no longer handled by the CGI page for
924 DNS resolution failures.
925 - CGI pages use favicons to signal whether they are error
926 or control pages. This is useful if you rely heavily on
928 - The show-url-info CGI page shows the forwarding settings.
929 - "Crunch!" log messages (used when Privoxy answers requests
930 by itself) now also contain the reason.
931 - Allow to rewrite the request destination behind the client's back.
932 - Fix socks requests on big-endian platforms. Patch provided by Song Weijia.
933 - Fixes possible deadlocks and crashes on OpenBSD.
934 Patch provided by Ralf Horstmann.
935 - The CGI action editor allows to edit actionfiles with previously
936 forbidden characters like dots.
937 - New trust entries are saved with a comment that contains the
938 trusted referring URL (Suggested by Daniel Griscom).
939 - Filter descriptions are HTML encoded automatically.
940 - New config option "split-large-forms" to work
941 around a browser bug that caused IE6 and IE7 to ignore
942 the Submit button on the edit-actions-for-url CGI page.
943 - New config option "allow-cgi-request-crunching" to allow
944 requests for Privoxy's CGI pages to be blocked, redirected
945 or (un)trusted like ordinary requests.
946 - Empty filter files no longer interrupt the filtering process
947 prematurely and are correctly listed on the show-status CGI page.
948 - New config option "accept-intercepted-requests" to combine
949 Privoxy with any packet filter to build an intercepting proxy
950 for HTTP/1.1 requests (and for HTTP/1.0 requests with Host header set).
951 - fast-redirects{} catch redirects to https URLs as well.
952 - redirect{s@foo@bar@} can be used to redirect to a rewritten
953 version of the original URL.
954 - Trap unsupported gopher proxy requests.
955 - Fixed a bug in the User Manual delivery on Windows
956 (mingw32 only). Images now show up correctly and HTML
957 pages are no longer padded with garbage data.
958 - Fixed several minor memory leaks, most of them discovered with Valgrind.
959 - Only unlink the pidfile if it's actually used.
960 - Retries after connection problems with forced requests
961 aren't blocked again.
962 - On Unix SIGABRT causes a core dump as expected and is no
963 longer treated as normal shutdown signal.
964 - The "access denied" CGI page is more descriptive and
965 allows retries to circumvent the referrer check.
966 - Updated PCRS to handle unexpected PCRE errors properly.
967 Fixed crashes that could occur if Privoxy was build
968 with external PCRE versions newer than Privoxy's internal
969 one. (Reported by Chung-chieh Shan)
970 - Fixed crashes with null bytes in PCRS replacement strings
971 (Patch provided by Felix Gröbert).
972 - Fixed crashes with header time randomization on mingw32.
973 - The CGI style sheet is no longer delivered if the referring
974 page isn't a Privoxy CGI page. This prevents a JavaScript-based
975 Privoxy detection "attack". Note that detecting Privoxy is
976 still possible through other ways and Privoxy was never intended
977 to be invisible anyway.
978 - Added support for AmigaOS 4, fixed build for AmigaOS 3.x.
979 - The show-url-info CGI page displays a warning if Privoxy
980 is currently toggled off.
981 - The show-status CGI page suppresses the edit button
982 for action files if Privoxy has no write access.
983 - Most CGI error pages react properly to HEAD requests.
984 - Requests with RFC 3253 HTTP methods (used by Subversion)
985 are accepted. (Patch provided by Petr Kadlec)
986 - New config option "templdir" to change the location
987 of the CGI templates to make sure customized templates
989 - Better handling of "HTTP/1.1 100 Continue" responses.
990 - The background of the PNG pattern is transparent.
991 - Fixed XML syntax errors caused by banners-by-size and banners-by-url.
992 - Fixed crashes and possible action file corruptions
993 when lines containing hashes are written through the CGI editor.
994 - Supports dynamic filters which can contain variables.
995 - Supports tags to change the actions based on client or server headers.
996 - Incorrect actions are logged before program termination.
997 - The "actionsfile" syntax in the configuration file is consistent
998 with the rest of the configuration options and requires the
999 whole file name. This is an incompatible change, if you use
1000 an old configuration file you might have to append ".action"
1001 to your "actionsfile" directives.
1002 - With the configuration file option "enforce-blocks" the
1003 "go there anyway" mechanism can be disabled without recompiling
1005 - More precise error messages in case of incorrect acl syntax.
1006 - Logs a warning if filtering is enabled but impossible due
1007 to lack of zlib support or use of the prevent-compression action.
1008 - Less noisy handling of Cookie:" and "Connection:" headers.
1009 - Improved error messages in case of connection problems.
1010 - Fix a command-line-parsing bug that was introduced before 3.0.5
1011 beta and caused Privoxy to treat the last argument as configuration
1012 file if no configuration file was specified.
1013 - Treat unknown command line options as fatal errors instead
1014 of silently ignoring them.
1015 - Use string functions with length checks more often.
1016 - Don't log CONNECT requests twice.
1017 - Allow to log the source address for ACL-related connection drops.
1018 - Don't ignore applying filters if the server didn't
1019 specify a Content-Type. Bug reported by Amuro Namie.
1020 - Rejected CONNECT requests are logged with log level info
1021 (enabled by default) and the reason for the block.
1022 - New command line option "--pre-chroot-nslookup hostname" to
1023 intialize the resolver library before chroot'ing. On some systems this
1024 reduces the number of files that must be copied into the chroot tree.
1025 (Patch provided by Stephen Gildea)
1026 - Fix a long-standing memory corruption bug that could cause
1027 Privoxy to overwrite a single byte in memory it didn't explicitly
1028 allocate (but that probably was allocated anyway due to bucket size).
1029 - Send template-based CGI pages as HTTP/1.1 unless the client
1031 - Let the first line in connection established responses
1032 end in \r\n as required by RFC1945. Reported by Bert van Leeuwen.
1033 - If no log file has been specified, disable logging instead of logging
1035 - Don't block stderr when in daemon mode.
1036 - Ignore missing zero-chunks when filtering chunk-encoded content.
1037 Earlier Privoxy versions would buffer and then forward the content
1038 unmodified which caused some browsers to simply show empty pages.
1039 - Fix double free in cgi_edit_actions_list(). Reported by Venustech AD-LAB.
1040 - The code to add X-Forwarded-For headers when the hide-forwarded-for-headers
1041 action isn't being used has been removed.
1042 - Fixed trustfile feature which previously didn't work without FEATURE_TOGGLE.
1044 - Minor code clean-ups, filter and action file updates.
1045 (Some of them reported by Davide Alberani, Markus Elfring,
1046 Stefan Huehner and Adam Piggott)
1048 *** Version 3.0.6 ***
1050 - New content filters: no-ping, google, msn, yahoo and blogspot.
1051 - New header filters: x-httpd-php-to-html, html-to-xml, xml-to-html
1052 and hide-tor-exit-notation.
1053 - The special header "X-Filter: No" now disables header filtering as well.
1054 - Improved the filters img-reorder, js-annoyances, webbugs,
1055 banners-by-size, banners-by-link and ie-exploits to make them
1056 less likely to break anything.
1057 - Removed outdated URL patterns in default.action and added new ones.
1058 - Added redirection from http://p.p/user-manual to http://p.p/user-manual/
1059 - Changed webinterface default values for hide-user-agent, hide-referrer
1060 and set-image-blocker.

1065 - Windows icon stays blue when Privoxy is idle, green when busy.
1066 - Integrated Fabian Keil's extensive patch. See:
1067 http://www.fabiankeil.de/sourcecode/privoxy/. Includes the
1068 following new or significantly improved actions (among many
1069 other improvements):
1071 content-type-overwrite{}
1072 crunch-client-header{string}
1073 crunch-if-none-match
1074 crunch-server-header{string}
1075 fast-redirects{check-decoded-url}
1076 filter-client-headers
1077 filter-server-headers
1079 handle-as-empty-document
1080 hide-accept-language{}
1081 hide-content-disposition{}
1082 hide-if-modified-since
1083 hide-referrer{conditional-block}
1084 overwrite-last-modified{}
1086 treat-forbidden-connects-like-blocks

1111 - Fixed yet another two memory leaks. Process growth seems stopped now.
1112 - Further tightened security against malicious toggle-off links.
1113 - Excluded text/plain MIME types from filtering. This fixes a
1114 couple of client-crashing, download corruption and
1115 Privoxy performance issues, whose root cause lies in
1116 web servers labelling content of unknown type as text/plain.
1117 - Assorted fixes for POSIX compliance, signal handling, graceful
1118 termination, compiler warnings, OSX support, Win32 systray,
1119 error logging, hostname wildcards, correct detection of NetBSD.
1120 - Workarounds for client (iTunes etc) and server (PHP < 4.2.3) bugs

1137 img-reorder, banners-by-size, banners-by-link, webbugs, refresh-tags,
1138 html-annoyances, content-cookies and fun filters
1139 - Replaced filter "popups" by choice between two modes:
1140 - "unsolicited-popups" tries to catch only the unsolicited ones
1141 - "all-popups" tries to kill them all (as before)
1142 - New filter "tiny-textforms" Help those tiny or hard-wrap textareas.
1143 - New filter "jumping-windows" that prevents windows from resizing
1144 and moving themselves
1145 - New filter "demoronizer" which fixes MS's abuse of std charsets
1146 (common cases anyway).
1147 - Replaced "nimda" with more general "ie-exploits" filter in which
1148 all filters for exploits shall be collected
1149 - Improved cookie logging
1150 - Rewrote make install target. Added uninstall and install-strip
1152 - Fixed a potential (application-level, NOT OS-level!) security
1153 problem involving remote toggling and action file manipulation
1154 by mailicious websites.
1155 - Added ability to chroot (thanks to Sviatoslav Sviridov)

1174 - Assorted small fixes and doc enhancements
1176 *** Version 2.9.16 ***
1178 - Major revamp of default.action to get rid of years of cruft.
1179 - Same for default.filter

1204 - Various other minor fixes.
1206 *** Version 2.9.13 Beta ***
1208 - *NEWS*: The project has been renamed to Privoxy! The new name is
1209 reflected throughout (file locations, etc).
1210 - ijb.action is now default.action. re_filterfile is now
1212 - http://i.j.b/ is now http://p.p/

1240 - Fix restart failure where sockets were in TIME_WAIT.
1241 - Fixes for actions cgi editor, make sure we have right file.
1242 - A --pidfile command line option now, in addition to --help,
1243 --version, --no-daemon, --user and configfile. --no-daemon replaces
1244 the former -d option and _DEBUG define. --user will drop privileges
1245 to the specified user.

1280 - Many other minor bugfixes
1281 - Start a ChangeLog :)
1285 *** Version 2.9.3 pre-Alpha Changes ***
1287 - Amiga support (completely untested by me - I don't have an Amiga)
1288 - "tinygif 3" support (redirects blocked images to a specified URL, so
1289 the browser doesn't have to load and cache many copies of the same
1291 - one case where there were both local and global "referrer" variables
1292 (yuck!) clarified by renaming the local one to "refer".
1293 - Fixed some places where close() was used instead of close_socket().
1294 Thanks to Jörg Strohmayer (joergs at users.sourceforge.net) for these.
1295 - Temporary hack to get FORCE_LOAD to work with IE. I just lowercased the
1296 FORCE_LOAD_PREFIX. Needs fixing properly.
1297 - Most URLs hardcoded into Junkbuster were changed to go through a script
1298 e.g. http://ijbswa.sourceforge.net/redirect.php?v=2.9.3&to=faq
1299 The only other URLs left are the GNU GPL:
1300 http://www.fsf.org/copyleft/gpl.html
1302 http://ijbswa.sourceforge.net/
1303 ... and various URLs which will be intercepted by Junkbuster anyway.
1304 TODO: Still need to do something with the URLs in Junkbuster Corp's
1305 copyright/trademark notice on the bottom of the show-proxy-args page.
1306 - PCRE or GNU Regex is now a #define option.
1309 *** Version 2.9.2 pre-Alpha Changes ***
1311 - Andreas applied the latest version of the FORCE patch.
1314 *** Version 2.9.1 pre-Alpha Changes ***
1316 - in parsers.c, fixed two #ifdef FORCE to #ifdef FORCE_LOAD
1317 (BTW: I think FORCE is precise enough, since loading remote
1318 data is the whole purpose of a proxy..)
1319 - Set the FORCE_PREFIX (back) to 'IJB-FORCE-LOAD-'. While 'noijb.'
1320 is more elegant and looks like a hostname in the URL, it doesn't
1321 make clear to the inexperienced user that the proxy is bypassed. It
1322 also has a higher name collision risk.
1323 - Filled in the function header templates for my functions in
1324 parsers.c (again). They obviously got lost in our current
1326 - Cut the credit for the §-referrer-option from the config file,
1327 that Stefan had placed there.
1328 - Improved the re_filterfile
1331 *** Version 2.9.0 pre-Alpha Changes ***
1333 - Now use PCRE, not GNU REGEX. I have not yet had chance to check the
1334 syntax of the block/image/cookie file to ensure that they match what
1335 is expected - however they seem to work.
1336 - Replaced "configure" script with one generated by "autoconf". Also
1337 use a header "config.h" (was ijbconfig.h in my previous release) for
1338 the #defines. "config.h" is now generated with "autoheader" from
1339 "acconfig.h" and "configure.in". (Note that to install you do not
1340 need autoconf or autoheader - just run "./configure".)
1341 To see command-line options, run "./configure --help".
1342 This is my first ever autoconf script, so it has some rough edges
1343 (how PCRE is handled is the roughest).
1344 - Error logging code replaced with new module errlog.c, based on the
1345 one from JunkbusterMT (but with the threading code removed).
1346 - Most of Rodney's 0.21 and 0.21A patches applied. (Marked *). I did not
1347 apply all of these, since I had already independently done conditional
1348 popup file, conditional image file, and integration of popup code.
1349 - ACL, Jar and trust files conditionally compiled.
1350 - New source file headers.
1351 - Various cosmetic changes. (But I have not consistently ordered the
1352 config files - I think that's worthwhile, but it's 1am and I want to
1354 - RCS tags on .h files.
1355 - RCS tags are const char[] rather than const char *. (Saves 4 bytes
1357 - VC++ project files renamed to vc_junkbuster.*.
1358 - show-proxy-args now shows status of all conditionals, not just REGEX
1359 - Various functions moved around. Most notably all the system-specific
1360 sockets code which was spread between jcc.c, bind.c, and connect.c,
1361 has been moved to "jbsockets.c". The non-system-specific code from
1362 connect.c and socks4.c has been movet to "gateway.c". Also, the
1363 config file loader and the global variables it writes to have been
1364 moved to "loadcfg.c". (Maybe this should go into loaders.c?)
1365 And candidate for the "worst filename ever" award is "miscutil.c",
1366 which contains, well, miscellaneous utility functions like zalloc.
1367 (Suggestions for a better name for this file are welcome!)
1368 - Loaders now use a common function to read a line and skip comments,
1369 and this function also stores the proxy_args.
1370 - Added ./junkbuster --help (Not for Win32 GUI)
1371 - Added ./junkbuster --version (Not for Win32 GUI)
1372 - Win32 resources are now all marked as "U.S. English", rather than
1373 being a mix of "U.S. English", "U.K. English" and "Irish English".
1374 - Version number changes to 2.9.0
