4 *** Version 3.0.20 Beta ***
7 - Fix --disable-ipv6-support compile option for the Windows platform
8 - Attempt to work around (or at least reduce the) video playback issues with
9 various Apple clients as reported in #3426305. In client_range(), let
10 headers pass if the range starts at the beginning.
11 - In pcrs_get_delimiter(), do not use delimiters ouside the ASCII range.
12 Fixes a clang complaint.
13 - In socks5_connect(), do not try to print a negative number of socks
14 response bytes if the read() for the socks5 negotiation failed
15 completely. It's an API violation and can trigger an assert() in debug
16 builds with "debug 2" enabled. Except for the assert(), log_error()
17 already handled negative %N values gracefully so this commit only makes a
18 difference for debug builds.
19 - Fix a Windows-specific log viewer thread safety issue, as reported by Tim
21 - Do not confuse a client hanging up with a connection time out. If a client
22 closes its side of the connection without sending a request line, do not
23 send the CLIENT_CONNECTION_TIMEOUT_RESPONSE, but report the condition
25 - Fix latency calculation for shared connections; broken since a regression
26 in 2009. The calculated latency for most connections would be 0 due to
27 remember_connection() always putting the timestamps in the first slot.
28 - Let fatal_error() write to the logfile right away, before showing the
29 Windows-specific error message which blocks until the user acknowledges it,
30 thus complicating automatic error detection. Reported by Adriaan in
32 - Fix an error message in get_last_url() nobody is supposed to see. Reported
33 by Matthew Fischer in #3507301.
34 - Fix a typo in the no-zlib-support complaint. Patch submitted by Matthew
36 - Update an error message that still tried to print directive_hash as long
37 - Let server_set_cookie() stay silent when the cookie isn't modified. It
38 previously would claim to have created a session cookie after letting a
39 session cookie pass unmodified.
40 - Make any_loaded_file_changed() more reliable. Using the timestamps from. If
41 an action or filter file is reloaded the timestamps aren't updated so
42 any_loaded_file_changed() continued to report file changes.
44 - General improvements:
45 - New debug log level 65536 which logs all actions that were applied to each
46 request that Privoxy acts upon.
47 - New directive client-header-order can be used to forward client headers in
48 a different order than that in which they arrived.
49 - New directive tolerate-pipelining can be used to enable client-side
50 pipelining. If enabled (3.0.20 beta enables it by default), Privoxy will
51 keep pipelined client requests around to deal with them once the current
52 request has been served. At the moment this is only done if the current
53 request is known to have no body.
54 - New --config-test option lets Privoxy exit after checking whether or not
55 the configuration seems valid. The limitations noted in TODO #22 and #23
56 still apply. Logging the problem to the logfile if one is configured and
57 --no-daemon isn't used could be considered non-intuitive and might also
58 clobber messages emitted by an already running instance. Based on a patch
59 by Ramkumar Chinchani.
60 - Add limit-cookie-lifetime{} action. It can be used to let cookies expire
61 before the end of the session. limit-cookie-lifetime{0} creates session
62 cookies and can thus replace the session-cookies-only action in the future.
63 Idea originally suggested by Rick Sykes in #1049575.
64 - Increase the maximum number of actions files from 10 to 30. This is set by
65 the compiler directive MAX_AF_FILES so could always be modified by
66 recompilation, but the default value was too low since an unused file slot
67 is pretty inexpensive.
68 - Significantly improved reuse of open connections.
69 - Add support for chunk-encoded client request bodies. Previously
70 chunk-encoded request bodies weren't guaranteed to be forwarded correctly,
71 so this can also be considered a bug fix although chunk-encoded request
72 bodies aren't commonly used in the real world.
73 - Add support for Tor's optimistic-data SOCKS extension, which can reduce the
74 latency for requests on newly created connections. Currently only the
75 headers are sent optimistically and only if the client request has already
76 been read completely which rules out requests with large bodies.
77 - After preventing the client from pipelining, don't signal keep-alive
78 intentions. When looking at the response headers alone, it previously
79 wasn't obvious from the client's perspective that no additional responses
80 should be expected. This might improve compatibility with Opera (#3464439).
81 - Use new drain_and_close_socket() when closing client sockets in serve().
82 Hopefully this fixes the page truncation issue reported with Opera in
83 #3464439. Apparently on some platforms immediately closing a client socket
84 with both unread and written-but-not-yet-transmitted data may result in the
85 connection being torn down prematurely, in which case the client ends up
86 with an incomplete response. To prevent this, drain_and_close_socket()
87 shuts down our side of the connection (on platforms with shutdown()),
88 drains the unread data on the socket and finally calls close_socket().
89 - Reject URLs with invalid port. Previously they were parsed incorrectly and
90 characters between the port number and the first slash were silently
91 dropped as shown by curl test 187.
92 - Stop considering client sockets tainted after receving a request with body.
93 It hasn't been necessary for a while now and unnecessarily causes test
94 failures when using curl's test suite.
95 - Allow HTTP/1.0 clients to signal interest in keep-alive through the
96 Proxy-Connection header. While such client are rare in the real world, it
97 doesn't hurt and couple of curl tests rely on it.
98 - Only remove duplicated headers when filters are enabled. If they are not it
99 doesn't cause ill effects and the user might not want it. While at it,
100 downgrade the removal message to LOG_LEVEL_HEADER to clarify that it's not
101 an error in Privoxy and is unlikely to cause any problems in general.
102 Anonymously reported in #3599335.
103 - Accept a default-server-timeout of 0. It's the default after all.
104 - Accept a socket-timeout value of 0 seconds. Impatience isn't necessarily a
106 - Set the socket option SO_LINGER for the client socket in
107 accept_connection(). This should further reduce the chances of the client
108 getting an incomplete response, even though Privoxy wrote it in its
109 entirety to the socket.
110 - Let serve() wait for keep-alive-timeout seconds for new requests. The
111 server connection timeout is no longer relevant.
112 - Improve connection handling when connection sharing is enabled.
113 - Do not keep the client connection open if it has to be closed to mark the
115 - Shorten ssplit()'s prototype by removing the last two arguments. We always
116 want to skip empty fields and ignore leading delimiters, so having
117 parameters for this only complicates the API.
118 - Use an enum for the type of the action value.
119 - Rename action_name's member takes_value to value_type as it isn't used as
121 - Turn family mismatches in match_sockaddr() into fatal errors
122 - Let enlist_unique_header() verify that the caller didn't pass a header
123 containing either \r or \n.
124 - Change the hashes used in load_config() to unsigned int.
125 That's what hash_string() actually returns and using a potentiallly larger
126 type is at best useless.
127 - Use privoxy_tolower() instead of vanilla tolower() with manual casting of
129 - Move several variable declarations to the beginning of their code block.
130 It's how we usually do it and is apparently also required when compiling
131 with gcc 2.95. Initial patch submitted by Simon South in #3564815.
132 - Optionally let parse_header_time() sanity check strptime() results before
133 trusting them. Broken strptime() implementations have caused problems in
134 the past and the most recent offender seems to be FreeBSD's libc:
135 http://www.freebsd.org/cgi/query-pr.cgi?pr=173421
137 - Action file improvements:
138 - Remove the comment that indicated that updated versions of this file are
139 released on their own.
140 - Allow closing curly braces as part of action values as long as they are
142 - Block 'optimize.indieclick.com/' and 'optimized-by.rubiconproject.com/'

182 not working) submitted by David Bo.
183 - Add two unblock patterns for popup radio and TV players. Submitted by Adam
186 - Filter file improvements & bug fixes:
187 - Add a referer tagger
188 - Reduce the likelihood that the google filter messes up HTML-generating
189 JavaScript. Reported by Zeno Kugy in #3520260.
191 - Documentation improvements:
192 - Revised all OS X sections due to new packaging module (OSXPackageBuilder).
193 - Update the list of supported operating systems to clarify that all Windows
194 versions after 95 are expected to work and note that the platform-specific
195 code for AmigaOS and QNX currently isn't maintained.
196 - Update 'Signals' section, the only explicitly handled signals are SIGINT,
198 - Add Haiku to the list of operating systems on which Privoxy is known to
200 - Add DragonFly to the list of BSDs on which Privoxy is known to run.
201 - Removed references to redhat-specific documentation set since it no longer
203 - Removed references to building PDFs since we no longer do so.
204 - Multiple listen-address directives are supported since 3.0.18, correct the
205 documentation to say so.
206 - Remove bogus section about long and short being preferable to int.
207 - Corrected some Internet JunkBuster references to Privoxy.
208 - Removed references to www.junkbusters.com since it is no longer
209 maintained. Reported by Angelina Matson.
210 - Various grammar and spelling corrections
211 - Add a client-header-tagger{} example for disabling filtering for range
213 - Correct a URL the "Privoxy with Tor" FAQ
214 - Spell 'refresh-tags' correctly. Reported by Don in #3571927.
215 - Sort manpage options alphabetically
216 - Remove an incorrect sentence in the toggle section. The toggle state
217 doesn't affect whether or not the Windows version uses the tray icon and
218 having to toggle Privoxy off to not show the icon makes no sense anyway.
219 Reported by Zeno Kugy in #3596395.
220 - Add the DNT header to the client-header-order example.
221 - Add new contributors since 3.0.19.
223 - Log message improvements:
224 - When stopping to watch a client socket due to pipelining, additionally log
226 - log the client socket and its condition before closing it. This makes it
227 more obvious that the socket actually gets closed and should help when
228 diagnosing problems like #3464439.
229 - In case of SOCKS5 failures, do not explicitly log the server's response.
230 It hasn't helped so far and the response can already be logged by enabling
231 "debug 32768" anyway. This reverts v1.81 and the follow-up bug fix v1.84.
232 - Relocate the connection-accepted message from listen_loop() to serve().
233 This way it's printed by the thread that is actually serving the
234 connection which is nice when grepping for thread ids in log files. While
235 at it, use an upper-case first character which is more consistent with the
239 - Remove compatibility layer for versions prior to 3.0 since it has been
240 obsolete for more than 10 years now.
241 - Remove the ijb_isupper() and ijb_tolower() macros from parsers.c since
242 they aren't used in this file.
243 - Removed the 'Functions declared include:' comment sections since they tend
244 to be incomplete, incorrect and out of date and the benefit seems
246 - Various comment grammar and comprehensibility improvements.
247 - Remove a pointless fflush() call in chat(). Flushing all streams pretty
248 much all the time for no obvious reason is ridiculous.
249 - Relocate ijb_isupper()'s definition to project.h and get the ijb_tolower()
250 definition from there, too.
251 - Relocate ijb_isdigit()'s definition to project.h.
252 - Rename ijb_foo macros to privoxy_foo.
253 - Add malloc_or_die() which will allow to simplify code paths where malloc()
254 failures don't need to be handled gracefully.
255 - Add strdup_or_die() which will allow to simplify code paths where strdup()
256 failures don't need to be handled gracefully.
257 - Replace strdup() calls with strdup_or_die() calls where it's safe and
259 - Fix white-space around parentheses.
260 - Add missing white-space behind if's and the following parentheses.
261 - Unwrap a memcpy() call in resolve_hostname_to_ip().
262 - Declare pcrs_get_delimiter()'s delimiters[] static const.
263 - Various optimisations to remove dead code and merge inefficient code
264 structures for improved clarity, performance or code compactness.
265 - Various data type corrections.
266 - Change visibility of several code segments when compiling without
267 FEATURE_CONNECTION_KEEP_ALIVE enabled for clarity.
268 - Fix an assertion in pcrs_compile_replacement(), nul bytes are actually
271 - Privoxy-Regression-Test:
272 - Various grammar and spelling corrections in documentation and code.
273 - Additional tests for range requests with filtering enabled.
274 - Tests with mostly invalid range request.
275 - Log to STDOUT instead of STDERR.
276 - Add a couple of hide-if-modified-since{} tests with different date formats.
277 - Cleaned up the format of the regression-tests.action file to match the
278 format of default.action.
279 - Remove the "Copyright" line from print_version(). When using --help, every
280 line of screen space matters and thus shouldn't be wasted on things the
281 user doesn't care about.
283 - Add an 'Overwrite condition' directive to skip any matching tests before
284 it. As it has a global scope, using it is more convenient than clowning
285 around with the Ignore directive.
286 - Include the Privoxy version in the output.
287 - Privoxy-Log-Parser:
288 - Improve the --statistics performance by skipping sanity checks for input
289 that shouldn't affect the results anyway. In my non-scientific benchmarks
290 this reduces the runtime by about 45%. Also add a --strict-checks option
291 that enables some of the checks again, just in case anybody cares.
292 - Accept and highlight: Stopping to watch the client socket. There's already
293 another request waiting.
294 - Cleanup variable initialization in print_non_clf_message().
295 - Properly highlight the new log messages from get_request_line().
296 - Let get_percentage() show 0 of x as 0% even if x is 0 as well.
297 - Accept and ignore: Enlisting (sorted|left-over) header ...
298 - Accept the shiny new LOG_LEVEL_ACTIONS.
299 - Accept and highlight: Closing client socket 5. Keep-alive: 0, Socket
300 alive: 1. Data available: 0.
301 - Stop suppressing messages about accepted client connections and highlight
303 - Accept and highlight: Accepted connection from 10.0.0.1 on socket 5.
304 - Accept and highlight: Continuing buffering server headers from socket 5.
305 Bytes most recently read: 498.
306 - Accept and highlight: Client request 4 arrived in time on socket 7.
307 - Accept and highlight: Closing client socket 8. Keep-alive: 1. Socket
308 alive: 0. Data available: 0. Configuration file change detected: 0.
309 Requests received: 11.
310 - Accept and highlight: Drained 180 bytes before closing socket 6.
311 - Accept and highlight the extended log message for client sockets.
312 - Accept and highlight: Tainting client socket 7 due to unread data.
313 - Accept and highlight: Optimistically sending 318 bytes of client
314 headers intended for www.privoxy.org.
315 - Accept and highlight: Client request 8 has been pipelined on socket 7 and
316 the socket is still alive.
317 - Accept: There better be a request body.
318 - Accept and highlight: Shifting 360 pipelined bytes by 360 bytes.
319 - Accept and highlight: Multiple Content-Type headers detected. Removing and
320 ignoring: Content-Type: text/html.
323 - Bump generated Firefox version to 16.
325 - CGI interface improvements & bug fixes:
326 - Remove an unreasonable parameter limit in parse_cgi_parameters(). The new
327 parameter limit depends on the memory available and is currently unlikely
328 to be reachable, due to other limits in both Privoxy and common clients.
329 Reported by Andrew on ijbswa-users@.
330 - Catch ssplit() failures in parse_cgi_parameters().
331 - Deal with unsupported methods sent to the CGI pages by discarding any
332 data following the headers.
334 - GNUmakefile improvements:
335 - The dok-tidy target no longer taints documents with a tidy-mark
336 - Change RA_MODE from 0664 to 0644. Suggested by Markus Dittrich in
338 - Remove tidy's clean flag as it changes the scope of attributes.
339 Link-specific colors end up being applied to all text. Reported by Adam
341 - Leave it up to the user whether or not smart tags are inserted.
342 - Let w3m itself do the line wrapping for the config file. It works better
343 than fmt as it can honour pre tags causing less unintentional line breaks.
344 - Ditch a pointless '-r' passed to rm to delete files.
345 - Prevent completely empty lines in configure and try to unfold
346 unintentional line breaks.
347 - Let the config-file target optimistically update the original. Most of the
348 issues are fixed now and it makes diffing with git easier.
349 - Change WDUMP to generate ASCII. Add WDUMP_UTF8 to allow UTF-8 in the
350 AUTHORS file so the names are right.
351 - Stop pretending that lynx and links are supported for the documentation.
353 - configure improvements:
354 - On Haiku, do not pass -lpthread to the compiler. Haiku's pthreads
355 implementation is contained in its system library, libroot, so no
356 additional library needs to be searched. Patch submitted by Simon South in
358 - Additional Haiku-specific improvements. Disable checks intended for
359 multi-user systems as Haiku is presently single-user. Group Haiku-specific
360 settings in their own section, following the pattern for Solaris, OS/2 and
361 AmigaOS. Add additional library-related settings to remove the need for
362 providing configure with custom LDFLAGS. Submitted by Simon South in
364 - Several improvements for clarity, diffability and logic.
366 *** Version 3.0.19 Stable ***
369 - Prevent a segmentation fault when de-chunking buffered content.
370 It could be triggered by malicious web servers if Privoxy was
371 configured to filter the content and running on a platform
372 where SIZE_T_MAX isn't larger than UINT_MAX, which probably
373 includes most 32-bit systems. On those platforms, all Privoxy
374 versions before 3.0.19 appear to be affected.
375 To be on the safe side, this bug should be presumed to allow
376 code execution as proving that it doesn't seems unrealistic.
377 - Do not expect a response from the SOCKS4/4A server until it
378 got something to respond to. This regression was introduced
379 in 3.0.18 and prevented the SOCKS4/4A negotiation from working.
380 Reported by qqqqqw in #3459781.
382 - General improvements:
383 - Fix an off-by-one in an error message about connect failures.
384 - Use a GNUMakefile variable for the webserver root directory and
385 update the path. Sourceforge changed it which broke various
387 - Update the CODE_STATUS description.
389 *** Version 3.0.18 Stable ***
392 - If a generated redirect URL contains characters RFC 3986 doesn't
393 permit, they are (re)encoded. Not doing this makes Privoxy versions
394 from 3.0.5 to 3.0.17 susceptible to HTTP response splitting (CWE-113)
395 attacks if the +fast-redirects{check-decoded-url} action is used.
396 - Fix a logic bug that could cause Privoxy to reuse a server
397 socket after it got tainted by a server-header-tagger-induced
398 block that was triggered before the whole server response had
399 been read. If keep-alive was enabled and the request following
400 the blocked one was to the same host and using the same forwarding
401 settings, Privoxy would send it on the tainted server socket.
402 While the server would simply treat it as a pipelined request,
403 Privoxy would later on fail to properly parse the server's
404 response as it would try to parse the unread data from the
405 first response as server headers for the second one.
406 Regression introduced in 3.0.17.
407 - When implying keep-alive in client_connection(), remember that
408 the client didn't. Fixes a regression introduced in 3.0.13 that
409 would cause Privoxy to wait for additional client requests after
410 receiving a HTTP/1.1 request with "Connection: close" set
411 and connection sharing enabled.
412 With clients which terminates the client connection after detecting
413 that the whole body has been received it doesn't really matter,
414 but with clients that don't the connection would be kept open until
416 - Fix a subtle race condition between prepare_csp_for_next_request()
417 and sweep(). A thread preparing itself for the next client request
418 could briefly appear to be inactive.
419 If all other threads were already using more recent files,
420 the thread could get its files swept away under its feet.
421 So far this has only been reproduced while stress testing in
422 valgrind while touching action files in a loop. It's unlikely
423 to have caused any actual problems in the real world.
424 - Disable filters if SDCH compression is used unless filtering is forced.
425 If SDCH was combined with a supported compression algorithm, Privoxy
426 previously could try to decompress it and ditch the Content-Encoding
427 header even though the SDCH compression wasn't dealt with.
428 Reported by zebul666 in #3225863.
429 - Make a copy of the --user value and only mess with that when splitting
430 user and group. On some operating systems modifying the value directly
431 is reflected in the output of ps and friends and can be misleading.
432 Reported by zepard in #3292710.
433 - If forwarded-connect-retries is set, only retry if Privoxy is actually
434 forwarding the request. Previously direct connections would be retried
436 - Fixed a small memory leak when retrying connections with IPv6
438 - Remove an incorrect assertion in compile_dynamic_pcrs_job_list()
439 It could be triggered by a pcrs job with an invalid pcre
440 pattern (for example one that contains a lone quantifier).
441 - If the --user argument user[.group] contains a dot, always bail out
442 if no group has been specified. Previously the intended, but undocumented
443 (and apparently untested), behaviour was to try interpreting the whole
444 argument as user name, but the detection was flawed and checked for '0'
445 instead of '\0', thus merely preventing group names beginning with a zero.
446 - In html_code_map[], use a numeric character reference instead of '
447 which wasn't standardized before XHTML 1.0.
448 - Fix an invalid free when compiled with FEATURE_GRACEFUL_TERMINATION
449 and shut down through http://config.privoxy.org/die
450 - In get_actions(), fix the "temporary" backwards compatibility hack
451 to accept block actions without reason.
452 It also covered other actions that should be rejected as invalid.
453 Reported by Billy Crook.
455 - General improvements:
456 - Privoxy can (re)compress buffered content before delivering
457 it to the client. Disabled by default as most users wouldn't
459 - The +fast-redirects{check-decoded-url} action checks URL
460 segments separately. If there are other parameters behind
461 the redirect URL, this makes it unnecessary to cut them off
462 by additionally using a +redirect{} pcrs command.
463 Initial patch submitted by Jamie Zawinski in #3429848.
464 - When loading action sections, verify that the referenced filters
465 exist. Currently missing filters only result in an error message,
466 but eventually the severity will be upgraded to fatal.
467 - Allow to bind to multiple separate addresses.
468 Patch set submitted by Petr Pisar in #3354485.
469 - Set socket_error to errno if connecting fails in rfc2553_connect_to().
470 Previously rejected direct connections could be incorrectly reported
471 as DNS issues if Privoxy was compiled with IPv6 support.
472 - Adjust url_code_map[] so spaces are replaced with %20 instead of '+'
473 While '+' can be used by client's submitting form data, this is not
474 actually what Privoxy is using the lookups for. This is more of a
475 cosmetic issue and doesn't fix any known problems.
476 - When compiled without FEATURE_FAST_REDIRECTS, do not silently
477 ignore +fast-redirect{} directives
478 - Added a workaround for GNU libc's strptime() reporting negative
479 year values when the parsed year is only specified with two digits.
480 On affected systems cookies with such a date would not be turned
481 into session cookies by the +session-cookies-only action.
482 Reported by Vaeinoe in #3403560
483 - Fixed bind failures with certain GNU libc versions if no non-loopback
484 IP address has been configured on the system. This is mainly an issue
485 if the system is using DHCP and Privoxy is started before the network
486 is completely configured.
487 Reported by Raphael Marichez in #3349356.
488 Additional insight from Petr Pisar.
489 - Privoxy log messages now use the ISO 8601 date format %Y-%m-%d.
490 It's only slightly longer than the old format, but contains
491 the full date including the year and allows sorting by date
492 (when grepping in multiple log files) without hassle.
493 - In get_last_url(), do not bother trying to decode URLs that do
494 not contain at least one '%' sign. It reduces the log noise and
495 a number of unnecessary memory allocations.
496 - In case of SOCKS5 failures, dump the socks response in the log message.
497 - Simplify the signal setup in main().
498 - Streamline socks5_connect() slightly.
499 - In socks5_connect(), require a complete socks response from the server.
500 Previously Privoxy didn't care how much data the server response
501 contained as long as the first two bytes contained the expected
502 values. While at it, shrink the buffer size so Privoxy can't read
503 more than a whole socks response.
504 - In chat(), do not bother to generate a client request in case of
505 direct CONNECT requests. It will not be used anyway.
506 - Reduce server_last_modified()'s stack size.
507 - Shorten get_http_time() by using strftime().
508 - Constify the known_http_methods pointers in unknown_method().
509 - Constify the time_formats pointers in parse_header_time().
510 - Constify the formerly_valid_actions pointers in action_used_to_be_valid().
511 - Introduce a GNUMakefile MAN_PAGE variable that defaults to privoxy.1.
512 The Debian package uses section 8 for the man page and this
513 should simplify the patch.
514 - Deduplicate the INADDR_NONE definition for Solaris by moving it to jbsockets.h
515 - In block_url(), ditch the obsolete workaround for ancient Netscape versions
516 that supposedly couldn't properly deal with status code 403.
517 - Remove a useless NULL pointer check in load_trustfile().
518 - Remove two useless NULL pointer checks in load_one_re_filterfile().
519 - Change url_code_map[] from an array of pointers to an array of arrays
520 It removes an unnecessary layer of indirection and on 64bit system reduces
521 the size of the binary a bit.
522 - Fix various typos. Fixes taken from Debian's 29_typos.dpatch by Roland Rosenfeld.
523 - Add a dok-tidy GNUMakefile target to clean up the messy HTML
524 generated by the other dok targets.
525 - GNUisms in the GNUMakefile have been removed.
526 - Change the HTTP version in static responses to 1.1
527 - Synced config.sub and config.guess with upstream
528 2011-11-11/386c7218162c145f5f9e1ff7f558a3fbb66c37c5.
529 - Add a dedicated function to parse the values of toggles. Reduces duplicated
530 code in load_config() and provides better error handling. Invalid or missing
531 toggle values are now a fatal error instead of being silently ignored.
532 - Terminate HTML lines in static error messages with \n instead of \r\n.
533 - Simplify cgi_error_unknown() a bit.
534 - In LogPutString(), don't bother looking at pszText when not
535 actually logging anything.
536 - Change ssplit()'s fourth parameter from int to size_t.
537 Fixes a clang complaint.
538 - Add a warning that the statistics currently can't be trusted.
539 Mention Privoxy-Log-Parser's --statistics option as
540 an alternative for the time being.
541 - In rfc2553_connect_to(), start setting cgi->error_message on error.
542 - Change the expected status code returned for http://p.p/die depending
543 on whether or not FEATURE_GRACEFUL_TERMINATION is available.
544 - In cgi_die(), mark the client connection for closing.
545 If the client will fetch the style sheet through another connection
546 it gets the main thread out of the accept() state and should thus
547 trigger the actual shutdown.
548 - Add a proper CGI message for cgi_die().
549 - Don't enforce a logical line length limit in read_config_line().
550 - Slightly refactor server_last_modified() to remove useless gmtime*() calls.
551 - In get_content_type(), also recognize '.jpeg' as JPEG extension.
552 - Add '.png' to the list of recognized file extensions in get_content_type().
553 - In block_url(), consistently use the block reason "Request blocked by Privoxy"
554 In two places the reason was "Request for blocked URL" which hides the
555 fact that the request got blocked by Privoxy and isn't necessarily
556 correct as the block may be due to tags.
557 - In listen_loop(), reload the configuration files after accepting
558 a new connection instead of before.
559 Previously the first connection that arrived after a configuration
560 change would still be handled with the old configuration.
561 - In chat()'s receive-data loop, skip a client socket check if
562 the socket will be written to right away anyway. This can
563 increase the transfer speed for unfiltered content on fast
565 - The socket timeout is used for SOCKS negotiations as well which
566 previously couldn't timeout.
567 - Don't keep the client connection alive if any configuration file
568 changed since the time the connection came in. This is closer to
569 Privoxy's behaviour before keep-alive support for client connection
570 has been added and also less confusing in general.
571 - Treat all Content-Type header values containing the pattern
572 'script' as a sign of text. Reported by pribog in #3134970.
574 - Action file improvements:
575 - Moved the site-specific block pattern section below the one for the
576 generic patterns so for requests that are matched in both, the block
577 reason for the domain is shown which is usually more useful than showing
578 the one for the generic pattern.
579 - Remove -prevent-compression from the fragile alias. It's no longer
580 used anywhere by default and isn't known to break stuff anyway.
581 - Add a (disabled) section to block various Facebook tracking URLs.
582 Reported by Dan Stahlke in #3421764.
583 - Add a (disabled) section to rewrite and redirect click-tracking
584 URLs used on news.google.com.
585 Reported by Dan Stahlke in #3421755.
586 - Unblock linuxcounter.net/.
587 Reported by Dan Stahlke in #3422612.
588 - Block 'www91.intel.com/' which is used by Omniture.
589 Reported by Adam Piggott in #3167370.
590 - Disable the handle-as-empty-doc-returns-ok option and mark it as deprecated.
591 Reminded by tceverling in #2790091.
592 - Add ".ivwbox.de/" to the "Cross-site user tracking" section.
593 Reported by Nettozahler in #3172525.
594 - Unblock and fast-redirect ".awin1.com/.*=http://".
595 Reported by Adam Piggott in #3170921.
596 - Block "b.collective-media.net/".
597 - Widen the Debian popcon exception to "qa.debian.org/popcon".
598 Seen in Debian's 05_default_action.dpatch by Roland Rosenfeld.
599 - Block ".gemius.pl/" which only seems to be used for user tracking.
600 Reported by johnd16 in #3002731. Additional input from Lee and movax.
601 - Disable banners-by-size filters for '.thinkgeek.com/'.
602 The filter only seems to catch pictures of the inventory.
603 - Block requests for 'go.idmnet.bbelements.com/please/showit/'.
604 Reported by kacperdominik in #3372959.
605 - Unblock adainitiative.org/.
606 - Add a fast-redirects exception for '.googleusercontent.com/.*=cache'.
607 - Add a fast-redirects exception for webcache.googleusercontent.com/.
608 - Unblock http://adassier.wordpress.com/ and http://adassier.files.wordpress.com/.
610 - Filter file improvements:
611 - Let the yahoo filter hide '.ads'.
612 - Let the msn filter hide overlay ads for Facebook 'likes' in search
613 results and elements with the id 's_notf_div'. They only seem to be
614 used to advertise site 'enhancements'.
615 - Let the js-events filter additionally disarm setInterval().
616 Suggested by dg1727 in #3423775.
618 - Documentation improvements:
619 - Clarify the effect of compiling Privoxy with zlib support.
620 Suggested by dg1727 in #3423782.
621 - Point out that the SourceForge messaging system works like a black
622 hole and should thus not be used to contact individual developers.
623 - Mention some of the problems one can experience when not explicitly
624 configuring an IP addresses as listen address.
625 - Explicitly mention that hostnames can be used instead of IP addresses
626 for the listen-address, that only the first address returned will be
627 used and what happens if the address is invalid.
628 Requested by Calestyo in #3302213.
630 - Log message improvements:
631 - If only the server connection is kept alive, do not pretend to
632 wait for a new client request.
633 - Remove a superfluous log message in forget_connection().
634 - In chat(), properly report missing server responses as such
635 instead of calling them empty.
636 - In forwarded_connect(), fix a log message nobody should ever see.
637 - Fix a log message in socks5_connect(), a failed write operation
638 was logged as failed read operation.
639 - Let load_one_actions_file() properly complain about a missing
640 '{' at the beginning of the file.
641 Simply stating that a line is invalid isn't particularly helpful.
642 - Do not claim to listen on a socket until Privoxy actually does.
643 Patch submitted by Petr Pisar #3354485
644 - Prevent a duplicated LOG_LEVEL_CLF message when sending out
645 the "no-server-data" response.
646 - Also log the client socket when dropping a connection.
647 - Include the destination host in the 'Request ... marked for
648 blocking. limit-connect{...} doesn't allow CONNECT ...' message
649 Patch submitted by Saperski in #3296250.
650 - Prevent a duplicated log message if none of the resolved IP
651 addresses were reachable.
652 - In connect_to(), do not pretend to retry if forwarded-connect-retries
654 - When a specified user or group can't be found, put the name in
655 single-quotes when logging it.
656 - In rfc2553_connect_to(), explain getnameinfo() errors better.
657 - Remove a useless log message in chat().
658 - When retrying to connect, also log the maximum number of connection
660 - Rephrase a log message in compile_dynamic_pcrs_job_list().
661 Divide the error code and its meaning with a colon. Call the pcrs
662 job dynamic and not the filter. Filters may contain dynamic and
663 non-dynamic pcrs jobs at the same time. Only mention the name of
664 the filter or tagger, but don't claim it's a filter when it could
666 - In a fatal error message in load_one_actions_file(), cover both
667 URL and TAG patterns.
668 - In pcrs_strerror(), properly report unknown positive error code
669 values as such. Previously they were handled like 0 (no error).
670 - In compile_dynamic_pcrs_job_list(), also log the actual error code as
671 pcrs_strerror() doesn't handle all errors reported by pcre.
672 - Don't bother trying to continue chatting if the client didn't ask for it.
673 Reduces log noise a bit.
674 - Make two fatal error message in load_one_actions_file() more descriptive.
675 - In cgi_send_user_manual(), log when rejecting a file name due to '/' or '..'.
676 - In load_file(), log a message if opening a file failed.
677 The CGI error message alone isn't too helpful.
678 - In connection_destination_matches(), improve two log messages
679 to help understand why the destinations don't match.
680 - Rephrase a log message in serve(). Client request arrival
681 should be differentiated from closed client connections now.
682 - In serve(), log if a client connection isn't reused due to a
683 configuration file change.
684 - Let mark_server_socket_tainted() always mark the server socket tainted,
685 just don't talk about it in cases where it has no effect. It doesn't change
686 Privoxy's behaviour, but makes understanding the log file easier.
689 - Added a --disable-ipv6-support switch for platforms where support
690 is detected but doesn't actually work.
691 - Do not check for the existence of strerror() and memmove() twice
692 - Remove a useless test for setpgrp(2). Privoxy doesn't need it and
693 it can cause problems when cross-compiling.
694 - Rename the --disable-acl-files switch to --disable-acl-support.
695 Since about 2001, ACL directives are specified in the standard
697 - Update the URL of the 'Removing outdated PCRE version after the
698 next stable release' posting. The old URL stopped working after
699 one of SF's recent site "optimizations". Reported by Han Liu.
701 - Privoxy-Regression-Test:
702 - Added --shuffle-tests option to increase the chances of detection race conditions.
703 - Added a --local-test-file option that allows to use Privoxy-Regression-Test without Privoxy.
704 - Added tests for missing socks4 and socks4a forwarders.
705 - The --privoxy-address option now works with IPv6 addresses containing brackets, too.
706 - Perform limited sanity checks for parameters that are supposed to have numerical values.
707 - Added a --sleep-time option to specify a number of seconds to
708 sleep between tests, defaults to 0.
709 - Disable the range-requests tagger for tests that break if it's enabled.
710 - Log messages use the ISO 8601 date format %Y-%m-%d.
711 - Fix spelling in two error messages.
712 - In the --help output, include a list of supported tests and their default levels.
713 - Adjust the tests to properly deal with FEATURE_TOGGLE being disabled.
715 - Privoxy-Log-Parser:
716 - Perform limited sanity checks for command line parameters that
717 are supposed to have numerical values.
718 - Implement a --unbreak-lines-only option to try to revert MUA breakage.
719 - Accept and highlight: Added header: Content-Encoding: deflate
720 - Accept and highlight: Compressed content from 29258 to 8630 bytes.
721 - Accept and highlight: Client request arrived in time on socket 21.
722 - Highlight: Didn't receive data in time: a.fsdn.com:443
723 - Accept log messages with ISO 8601 time stamps, too.
726 - Bump generated Firefox version to 8.0.
727 - Only randomize the release date if the new --randomize-release-date
728 option is enabled. Firefox versions after 4 use a fixed date string
731 *** Version 3.0.17 Stable ***
733 - Fixed last-chunk-detection for responses where the body was small
734 enough to be read with the headers, causing Privoxy to wait for the
735 end of the content until the server closed the connection or the
736 request timed out. Reported by "Karsten" in #3028326.
737 - Responses with status code 204 weren't properly detected as body-less
738 like RFC2616 mandates. Like the previous bug, this caused Privoxy to
739 wait for the end of the content until the server closed the connection
740 or the request timed out. Fixes #3022042 and #3025553, reported by a
741 user with no visible name. Most likely also fixes a bunch of other
742 AJAX-related problem reports that got closed in the past due to
743 insufficient information and lack of feedback.
744 - Fixed an ACL bug that made it impossible to build a blacklist.
745 Usually the ACL directives are used in a whitelist, which worked
746 as expected, but blacklisting is still useful for public proxies
747 where one only needs to deny known abusers access.
748 - Added LOG_LEVEL_RECEIVED to log the not-yet-parsed data read from the
749 network. This should make debugging various parsing issues a lot easier.
750 - The IPv6 code is enabled by default on Windows versions that support it.
751 Patch submitted by oCameLo in #2942729.
752 - In mingw32 versions, the user.filter file is reachable through the
753 GUI, just like default.filter is. Feature request 3040263.
754 - Added the configure option --enable-large-file-support to set a few
755 defines that are required by platforms like GNU/Linux to support files
756 larger then 2GB. Mainly interesting for users without proper logfile
758 - Logging with "debug 16" no longer stops at the first nul byte which is
759 pretty useless. Non-printable characters are replaced with their hex value
760 so the result can't span multiple lines making parsing them harder then
762 - Privoxy logs when reading an action, filter or trust file.
763 - Fixed incorrect regression test markup which caused a test in
764 3.0.16 to fail while Privoxy itself was working correctly.
765 While Privoxy accepts hide-referer, too, the action name is actually
766 hide-referrer which is also the name used one the final results page,
767 where the test expected the alias.
769 - CGI interface improvements:
770 - In finish_http_response(), continue to add the 'Connection: close'
771 header if the client connection will not be kept alive.
772 Anonymously pointed out in #2987454.
773 - Apostrophes in block messages no longer cause parse errors
774 when the blocked page is viewed with JavaScript enabled.
775 Reported by dg1727 in #3062296.
776 - Fix a bunch of anchors that used underscores instead of dashes.
777 - Allow to keep the client connection alive after crunching the previous request.
778 Already opened server connections can be kept alive, too.
779 - In cgi_show_url_info(), don't forget to prefix URLs that only contain
780 http:// or https:// in the path. Fixes #2975765 reported by Adam Piggott.
781 - Show the 404 CGI page if cgi_send_user_manual() is called while
782 local user manual delivery is disabled.
784 - Action file improvements:
785 - Enable user.filter by default. Suggested by David White in #3001830.
786 - Block .sitestat.com/. Reported by johnd16 in #3002725.
787 - Block .atemda.com/. Reported by johnd16 in #3002723.
788 - Block js.adlink.net/. Reported by johnd16 in #3002720.
789 - Block .analytics.yahoo.com/. Reported by johnd16 in #3002713.
790 - Block sb.scorecardresearch.com, too. Reported by dg1727 in #2992652.
791 - Fix problems noticed on Yahoo mail and news pages.
792 - Remove the too broad yahoo section, only keeping the
793 fast-redirects exception as discussed on ijbswa-devel@.
794 - Don't block adesklets.sourceforge.net. Reported in #2974204.
795 - Block chartbeat ping tracking. Reported in #2975895.
796 - Tag CSS and image requests with cautious and medium settings, too.
797 - Don't handle view.atdmt.com as image. It's used for click-throughs
798 so users should be able to "go there anyway".
799 Reported by Adam Piggott in #2975927.
800 - Also let the refresh-tags filter remove invalid refresh tags where
801 the 'url=' part is missing. Anonymously reported in #2986382.
802 While at it, update the description to mention the fact that only
803 refresh tags with refresh times above 9 seconds are covered.
804 - javascript needs to be blocked with +handle-as-empty-document to
805 work around Firefox bug 492459. So move .js blockers from
806 +block{Might be a web-bug.} -handle-as-empty-document to
807 +block{Might be a web-bug.} +handle-as-empty-document.
808 - ijbswa-Feature Requests-3006719 - Block 160x578 Banners.
809 - Block another omniture tracking domain.
810 - Added a range-requests tagger.
811 - Added two sections to get Flickr's Ajax interface working with
812 default pre-settings. If you change the configuration to block
813 cookies by default, you'll need additional exceptions.
814 Reported by Mathias Homann in #3101419 and by Patrick on ijbswa-users@.
816 - Documentation improvements:
817 - Explicitly mention how to match all URLs.
818 - Consistently recommend socks5 in the Tor FAQ entry and mention
819 its advantage compared to socks4a. Reported by David in #2960129.
820 - Slightly improve the explanation of why filtering may appear
822 - Grammar fixes for the ACL section.
823 - Fixed a link to the 'intercepting' entry and add another one.
824 - Rename the 'Other' section to 'Mailing Lists' and reword it
825 to make it clear that nobody is forced to use the trackers
826 - Note that 'anonymously' posting on the trackers may not always
828 - Suggest to enable debug 32768 when suspecting parsing problems.
830 - Privoxy-Log-Parser improvements:
831 - Gather statistics for ressources, methods, and HTTP versions
833 - Also gather statistics for blocked and redirected requests.
834 - Provide the percentage of keep-alive offers the client accepted.
835 - Add a --url-statistics-threshold option.
836 - Add a --host-statistics-threshold option to also gather
837 statistics about how many request where made per host.
838 - Fix a bug in handle_loglevel_header() where a 'scan: ' got lost.
839 - Add a --shorten-thread-ids option to replace the thread id with
841 - Accept and ignore: Looks like we got the last chunk together
842 with the server headers. We better stop reading.
843 - Accept and ignore: Continue hack in da house.
844 - Accept and higlight: Rejecting connection from 10.0.0.2.
845 Maximum number of connections reached.
846 - Accept and highlight: Loading actions file: /usr/local/etc/privoxy/default.action
847 - Accept and highlight: Loading filter file: /usr/local/etc/privoxy/default.filter
848 - Accept and highlight: Killed all-caps Host header line: HOST: bestproxydb.com
849 - Accept and highlight: Reducing expected bytes to 0. Marking
850 the server socket tainted after throwing 4 bytes away.
851 - Accept: Merged multiple header lines to: 'X-FORWARDED-PROTO: http X-HOST: 127.0.0.1'
854 - Remove the next member from the client_state struct. Only the main
855 thread needs access to all client states so give it its own struct.
856 - Garbage-collect request_contains_null_bytes().
857 - Ditch redundant code in unload_configfile().
858 - Ditch LogGetURLUnderCursor() which doesn't seem to be used anywhere.
859 - In write_socket(), remove the write-only variable write_len in
860 an ifdef __OS2__ block. Spotted by cppcheck.
861 - In connect_to(), don't declare the variable 'flags' on OS/2 where
862 it isn't used. Spotted by cppcheck.
863 - Limit the scope of various variables. Spotted by cppcheck.
864 - In add_to_iob(), turn an interestingly looking for loop into a
866 - Code cleanup in preparation for external filters.
867 - In listen_loop(), mention the socket on which we accepted the
868 connection, not just the source IP address.
869 - In write_socket(), also log the socket we're writing to.
870 - In log_error(), assert that escaped characters get logged
871 completely or not at all.
872 - In log_error(), assert that ival and sval have reasonable values.
873 There's no reason not to abort() if they don't.
874 - Remove an incorrect cgi_error_unknown() call in a
875 cannot-happen-situation in send_crunch_response().
876 - Clean up white-space in http_response definition and
877 move the crunch_reason to the beginning.
878 - Turn http_response.reason into an enum and rename it
879 to http_response.crunch_reason.
880 - Silence a 'gcc (Debian 4.3.2-1.1) 4.3.2' warning on i686 GNU/Linux.
881 - Fix white-space in a log message in remove_chunked_transfer_coding().
882 While at it, add a note that the message doesn't seem to
883 be entirely correct and should be improved later on.
885 - GNUmakefile improvements:
886 - Use $(SSH) instead of ssh, so one only needs to specify a username once.
887 - Removed references to the action feedback thingy that hasn't been
889 - Consistently use shell.sourceforge.net instead of shell.sf.net so
890 one doesn't need to check server fingerprints twice.
891 - Removed GNUisms in the webserver and webactions targets so they
892 work with standard tar.
894 *** Version 3.0.16 Stable ***
896 - Added the config file option handle-as-empty-doc-returns-ok to
897 work around Firefox bug #492459, which causes Firefox to hang
898 if JavaScripts are blocked in certain situations. The option is
899 enabled in the default config file.
900 - Added the config file option default-server-timeout to control the
901 assumed default server timeout. Since Privoxy no longer returns
902 an error message for connection resets on reused client connections,
903 assuming larger server timeout values appears to actually work
904 pretty well as long as connections aren't shared.
905 - Added optional support for FreeBSD's accf_http(9). Use the
906 configure option --enable-accept-filter to enable it.
907 - Added fancier Privoxy icons for win32. Contributed by Jeff H.
908 - In daemon mode, fd 0, 1 and 2 are bound to /dev/null.
909 - Resolve localhost using whatever address family the operating
910 system feels like. Previous betas would try to use IPv4 as this
911 is what most users expect, but this didn't work reliably on
913 - In the action lists on CGI pages, actions and their parameters are
914 no longer separated with a space. The action file parser doesn't
915 actually allow this and will throw an invalid syntax error if actions
916 and parameters in the action files are separated. Not adding the
917 spaces means copy and pasting CGI output into the action files works.
918 - The default keep-alive timeout has been reduced to 5 seconds to work
919 around hangs in clients that treat the proxy like any other host and
920 stop allowing any new connections if the "maximum number of
921 connections per host" is reached.
922 - Several webbug URLs that look like they are leading to images are now
923 blocked as image instead of empty documents. Doing the latter causes
924 WebKit-based clients to show a "missing image" icon which may mess up
926 - The no-such-domain template is used for DNS resolution
927 problems with FEATURE_IPV6_SUPPORT enabled. Previously the
928 connect-failed template was used. Reported by 'zebul666'.
929 - Accepts quoted expiration dates even though RFC 2109 10.1.2
930 doesn't seem to allow them. Reported anonymously.
931 - Don't try to forget connections if connection sharing is disabled.
932 This wasn't a real problem but caused an unnecessary log message.
933 - The still undocumented --enable-extended-host-patterns configure
934 option has a better description.
935 - Fixed an error message that would claim a write to the server
936 failed when actually writing to the client failed.
937 - Log the crunch reason before trying to write to the client.
938 The log is easier to read that way.
939 - Several log messages about client connections also mention
941 - handle-as-empty-document no longer depends on the image blocking
943 - Privoxy-Log-Parser is roughly 40% faster in highlighting mode.
944 - uagen, a Firefox User-Agent generator for Privoxy and Mozilla
945 browsers has been imported and is available in the tarball's
947 - The scripts in the tools directory treat unknown parameters
950 *** Version 3.0.15 Beta ***
952 - In case of missing server data, no error message is send to the
953 client if the request arrived on a reused connection. The client
954 is then supposed to silently retry the request without bothering
955 the user. This should significantly reduce the frequency of the
956 "No server or forwarder data received" error message many users
958 - More reliable detection of prematurely closed client sockets
959 with keep-alive enabled.
960 - FEATURE_CONNECTION_KEEP_ALIVE is decoupled from
961 FEATURE_CONNECTION_SHARING and now available on
963 - Improved handling of POST requests on reused connections.
964 Should fix problems with stalled connections after submitting
965 form data with some browser configurations.
966 - Fixed various latency calculation issues.
967 - Allows the client to pass NTLM authentication requests to a
968 forwarding proxy. This was already assumed and hinted to work
969 in 3.0.13 beta but actually didn't. Now it's confirmed to work
970 with IE, Firefox and Chrome.
971 Thanks to Francois Botha and Wan-Teh Chang
972 - Fixed a calculation problem if receiving the server headers
973 takes more than two reads, that could cause Privoxy to terminate
974 the connection prematurely. Reported by Oliver.
975 - Compiles again on platforms such as OpenBSD and systems
976 using earlier glibc version that don't support AI_ADDRCONFIG.
977 Anonymously submitted in #2872591.
978 - A bunch of MS VC project files and Suse and Redhat RPM spec
979 files have been removed as they were no longer maintained for
981 - Overly long action lines are properly rejected with a proper
982 error message. Previously they would be either rejected as
983 invalid or cause a core dump through abort().
984 - Already timed-out connections are no longer temporarily remembered.
985 They weren't reused anyway, but wasted a socket slot.
986 - len refers to the number of bytes actually read which might
987 differ from the ones received. Adjust log messages accordingly.
988 - The optional JavaScript on the CGI page uses encodeURIComponent()
989 instead of escape() which doesn't encode all characters that matter.
990 Anonymously reported in #2832722.
991 - Fix gcc45 warnings in decompress_iob().
992 - Various log message improvements.
993 - Privoxy-Regression-Test supports redirect tests.
994 - Privoxy-Log-Parser can gather some connection statistics.
996 *** Version 3.0.14 Beta ***
998 - The latency is taken into account when evaluating whether or not to
999 reuse a connection. This should significantly reduce the number of
1000 connections problems several users reported.
1001 - If the server doesn't specify how long the connection stays alive,
1002 Privoxy errs on the safe side of caution and assumes it's only a second.
1003 - The error pages for connection timeouts or missing server data use a
1004 Last-Modified date in the past. Retry attempts are detected and Privoxy
1005 removes the If-Modified-Since header to prevent the server from responding
1006 with status code 304 in which case the client would reuse the error message.
1007 - Setting keep-alive-timeout to 0 disables keep-alive support. Previously
1008 Privoxy would claim to allow persistence but not reuse the connection.
1009 - Pipelined requests are less likely to be mistaken for the request
1010 body of the previous request. Note that Privoxy still has no real
1011 pipeline support and will either serialize pipelined requests or
1012 drop them in which case the client has to resent them.
1013 - Fixed a crash on some Windows versions when header randomization
1014 is enabled and the date couldn't be parsed.
1015 - Privoxy's keep-alive timeout for the current connection is reduced
1016 to the one specified in the client's Keep-Alive header.
1017 - For HTTP/1.1 requests, Privoxy implies keep-alive support by not
1018 setting any Connection header instead of using 'Connection: keep-alive'.
1019 - If the socket isn't reusable, Privoxy doesn't temporarily waste
1020 a socket slot to remember the connection.
1021 - If keep-alive support is disabled but compiled in, the client's
1022 Keep-Alive header is removed.
1023 - Fixed a bug on mingw32 where downloading large files failed if
1024 keep-alive support was enabled.
1025 - Fixed a bug that (at least theoretically) could cause log
1026 timestamps to be occasionally off by about a second.
1027 - No Proxy-Connection header if added if there already is one.
1028 - The configure script respects the $PATH variable when searching
1031 *** Version 3.0.13 Beta ***
1033 - Added IPv6 support. Thanks to Petr Pisar who not only provided
1034 the initial patch but also helped a lot with the integration.
1035 - Added client-side keep-alive support.
1036 - The connection sharing code is only used if the connection-sharing
1038 - The max-client-connections option has been added to restrict
1039 the number of client connections below a value enforced by
1040 the operating system.
1041 - Fixed a regression reintroduced in 3.0.12 that could cause
1042 crashes on mingw32 if header date randomization was enabled.
1043 - Compressed content with extra fields couldn't be decompressed
1044 and would get passed to the client unfiltered. This problem
1045 has only be detected through statical analysis with clang as
1046 nobody seems to be using extra fields anyway.
1047 - If the server resets the Connection after sending only the headers
1048 Privoxy forwards what it got to the client. Previously Privoxy
1049 would deliver an error message instead.
1050 - Error messages in case of connection timeouts use the right
1052 - If spawning a child to handle a request fails, the client
1053 gets an error message and Privoxy continues to listen for
1054 new requests right away.
1055 - The error messages in case of server-connection timeouts or
1056 prematurely closed server connections are now template-based.
1057 - If zlib support isn't compiled in, Privoxy no longer tries to
1058 filter compressed content unless explicitly asked to do so.
1059 - In case of connections that are denied based on ACL directives,
1060 the memory used for the client IP is no longer leaked.
1061 - Fixed another small memory leak if the client request times out
1062 while waiting for client headers other than the request line.
1063 - The client socket is kept open until the server socket has
1064 been marked as unused. This should increase the chances that
1065 the still-open connection will be reused for the client's next
1066 request to the same destination. Note that this only matters
1067 if connection-sharing is enabled.
1068 - A TODO list has been added to the source tarball to give potential
1069 volunteers a better idea of what the current goals are. Donations
1070 are still welcome too: http://www.privoxy.org/faq/general.html#DONATE
1072 *** Version 3.0.12 ***
1074 - The socket-timeout option now also works on platforms whose
1075 select() implementation modifies the timeout structure.
1076 Previously the timeout was triggered even if the connection
1077 didn't stall. Reported by cyberpatrol.
1078 - The Connection: keep-alive code properly deals with files
1079 larger than 2GB. Previously the connection was closed too
1081 - The content length for files above 2GB is logged correctly.
1082 - The user-manual directive on the show-status page links to
1083 the documentation location specified with the directive,
1084 not to the Privoxy website.
1085 - When running in daemon mode, Privoxy doesn't log anything
1086 to the console unless there are errors before the logfile
1088 - The show-status page prints warnings about invalid directives
1089 on the same line as the directives themselves.
1090 - Fixed several justified (but harmless) compiler warnings,
1091 mostly on 64 bit platforms.
1092 - The mingw32 version explicitly requests the default charset
1093 to prevent display problems with some fonts available on more
1094 recent Windows versions. Patch by Burberry.
1095 - The mingw32 version uses the Privoxy icon in the alt-tab
1096 windows. Patch by Burberry.
1097 - The timestamp and the thread id is omitted in the "Fatal error"
1098 message box on mingw32.
1099 - Fixed two related mingw32-only buffer overflows. Triggering
1100 them required control over the configuration file, therefore
1101 this isn't seen as a security issue.
1102 - In verbose mode, or if the new option --show-skipped-tests
1103 is used, Privoxy-Regression-Test logs skipped tests and the
1106 *** Version 3.0.11 ***
1108 - On most platforms, outgoing connections can be kept alive and
1109 reused if the server supports it. Whether or not this improves
1110 things depends on the connection.
1111 - When dropping privileges, membership in supplementary groups
1112 is given up as well. Not doing that can lead to Privoxy running
1113 with more rights than necessary and violates the principle of
1114 least privilege. Users of the --user option are advised to update.
1115 Thanks to Matthias Drochner for reporting the problem,
1116 providing the initial patch and testing the final version.
1117 - Passing invalid users or groups with the --user option
1118 didn't lead to program exit. Regression introduced in 3.0.7.
1119 - The match all section has been moved from default.action
1120 to a new file called match-all.action. As a result the
1121 default.action no longer needs to be touched by the user
1122 and can be safely overwritten by updates.
1123 - The standard.action file has been removed. Its content
1124 is now part of the default.action file.
1125 - In some situations the logged content length was slightly too low.
1126 - Crunched requests are logged with their own log level.
1127 If you used "debug 1" in the past, you'll probably want
1128 to additionally enable "debug 1024", otherwise only passed
1129 requests will be logged. If you only care about crunched
1130 requests, simply replace "debug 1" with "debug 1024".
1131 - The crunch reason has been moved to the beginning of the
1132 crunch message. For HTTP URLs, the protocol is logged as well.
1133 - Log messages are shortened by printing the thread id on its
1134 own (as opposed to putting it inside the string "Privoxy()").
1135 - The config option socket-timeout has been added to control
1136 the time Privoxy waits for data to arrive on a socket.
1137 - Support for remote toggling is controlled by the configure
1138 option --disable-toggle only. In previous versions it also
1139 depended on the action editor and thus configuring with the
1140 --disable-editor option would disable remote toggling support
1142 - Requests with invalid HTTP versions are rejected.
1143 - The template symbol @date@ can be used to include a date(1)-like
1144 time string. Initial patch submitted by Endre Szabo.
1145 - Responses from shoutcast servers are accepted again.
1146 Problem reported and fix suggested by Stefan.
1147 - The hide-forwarded-for-headers action has been replaced with
1148 the change-x-forwarded-for{} action which can also be used to
1149 add X-Forwarded-For headers. The latter functionality already
1150 existed in Privoxy versions prior to 3.0.7 but has been removed
1151 as it was often used unintentionally (by not using the
1152 hide-forwarded-for-headers action).
1153 - A "clear log" view option was added to the mingw32 version
1154 to clear out all of the lines in the Privoxy log window.
1155 Based on a patch submitted by T Ford.
1156 - The mingw32 version uses "critical sections" now, which prevents
1157 log message corruption under load. As a side effect, the
1158 "no thread-safe PRNG" warning could be removed as well.
1159 - The mingw32 version's task bar icon is crossed out and
1160 the color changed to gray if Privoxy is toggled off.
1162 *** Version 3.0.10 ***
1164 - Ordinary configuration file changes no longer cause program
1165 termination on OS/2 if the name of the logfile hasn't been
1166 changed as well. This regression probably crept in with the
1167 logging improvements in 3.0.7. Reported by Maynard.
1168 - The img-reorder filter is less likely to mess up JavaScript code in
1169 img tags. Problem and solution reported by Glenn Washburn in #2014552.
1170 - The source tar ball now includes Privoxy-Log-Parser,
1171 a syntax-highlighter for Privoxy logs. For fancy screenshots see:
1172 http://www.fabiankeil.de/sourcecode/privoxy-log-parser/
1173 Documentation is available through perldoc(1).
1175 *** Version 3.0.9 Beta ***
1177 - Added SOCKS5 support (with address resolution done by
1178 the SOCKS5 server). Patch provided by Eric M. Hopper.
1179 - The "blocked" CGI pages include a block reason that was
1180 provided as argument to the last-applying block action.
1181 - If enable-edit-actions is disabled (the default since 3.0.7 beta)
1182 the show-status page hides the edit buttons and explains why.
1183 Previously the user would get the "this feature has been disabled"
1184 message after using the edit button.
1185 - Forbidden CONNECT requests are treated like blocks by default.
1186 The now-pointless treat-forbidden-connects-like-blocks action
1188 - Not enabling limit-connect now allows CONNECT requests to all ports.
1189 In previous versions it would only allow CONNECT requests to port 443.
1190 Use +limit-connect{443} if you think you need the old default behaviour.
1191 - The CGI editor gets turned off after three edit requests with invalid
1192 file modification timestamps. This makes life harder for attackers
1193 who can leverage browser bugs to send fake Referers and intend to
1194 brute-force edit URLs.
1195 - Action settings for multiple patterns in the same section are
1196 shared in memory. As a result these sections take up less space
1197 (and are loaded slightly faster). Problem reported by Franz Schwartau.
1198 - Linear white space in HTTP headers will be normalized to single
1199 spaces before parsing the header's content, headers split across
1200 multiple lines get merged first. This should prevent problems like:
1201 * letting the session-cookies-only action slip
1202 some Cookies through unmodified,
1203 * only suppressing the first line of a header,
1204 thus creating an invalid one, and
1205 * to incorrectly block headers with valid timestamps
1206 that weren't properly recognized.
1207 Headers that could trigger these problems are unlikely to appear
1208 in "normal" web traffic, but could be intentionally generated to
1209 fool some of Privoxy's header parsers.
1210 - Host information is gathered outside the main thread so it's less
1211 likely to delay other incoming connections if the host is misconfigured.
1212 - New config option "hostname" to use a hostname other than
1213 the one returned by the operating system. Useful to speed-up responses
1214 for CGI requests on misconfigured systems. Requested by Max Khon.
1215 - The CGI editor supports the "disable all filters of this type"
1216 directives "-client-header-filter", "-server-header-filter",
1217 "-client-header-tagger" and "-server-header-tagger".
1218 - Fixed false-positives with the link-by-url filter and URLs that
1219 contain the pattern "/jump/".
1220 - The less-download-windows filter no longer messes
1221 "Content-Type: application/x-shockwave-flash" headers up.
1222 - In the show-url-info page's "Final results" section active and
1223 inactive actions are listed separately. Patch provided by Lee.
1224 - The GNUmakefile supports the DESTDIR variable. Patch for
1225 the install target submitted by Radoslaw Zielinski.
1226 - Embedding the content of configuration files in the show-status
1227 page is significantly faster now. For a largish action file (1 MB)
1228 a speedup of about 2450 times has been measured. This is mostly
1229 interesting if you are using large action files or regularly use
1230 Privoxy-Regression-Test while running Privoxy through Valgrind,
1231 for stock configuration files it doesn't really matter.
1232 - If zlib support is unavailable and there are content
1233 filters active but the prevent-compression action is disabled,
1234 the show-url-info page includes a warning that compression
1235 might prevent filtering.
1236 - The show-url-info page provides an OpenSearch Description that
1237 allows to access the page through browser search plugins.
1238 - Custom client-header filters that rewrite the request line
1239 incorrectly no longer cause Privoxy to crash. Reported by din_a4.
1240 - The obsolete kill-popups action has been removed as the
1241 PCRS-based popup filters can do the same and are slightly
1243 - The inspect-jpegs action has been removed.
1244 - The send-wafer and send-vanilla-wafer actions have been removed.
1245 They weren't particular useful and their behaviour could be emulated
1246 with add-header anyway.
1247 - Privoxy-Regression-Test has been significantly improved.
1248 - Most sections in the default.action file contain tests for
1249 Privoxy-Regression-Test to verify that they are working as intended.
1250 - Parts of Privoxy have been refactored to increase maintainability.
1251 - Building with zlib (if available) is done by default.
1253 *** Version 3.0.8 ***
1255 - Fixed a small memory leak when listen-address only specifies the port.
1256 - The source tar balls now include Privoxy-Regression-Test which
1257 (upon other things) can be used to automatically detect some
1258 packaging problems. Packagers are welcome to give it a try.
1259 - Reverted a change in 3.0.7 that caused path patterns to be checked
1260 even if the host pattern match already failed. While this doesn't
1261 noticeable affect the performance, it makes it less likely to run
1262 out of stack space with overly-complex path patterns the user might
1264 - Updated the msn, yahoo and google filters to work as advertised again.
1265 - The warning message shown by the show-status CGI page is easier to
1266 understand. Previously it wasn't clear that the error message
1267 is shown below the invalid directive. (Reported by Lee)
1268 - When regenerating Content-Disposition headers the more common
1269 spelling is used for the name. Previously it was written without caps.
1270 - Less confusing log message if the content type isn't overwritten
1271 because force-text-type wasn't used but the old type doesn't look
1272 like content that would be filtered normally.
1273 - Better log messages if the user tries to execute filters that
1275 - Treat the non-standard Request-Range headers like standard range
1276 headers and suppress them if content filtering is enabled.
1277 - Prevent the log messages for CONNECT requests to unacceptable
1278 ports from printing the limit-connect argument as [null] if
1279 limit-connect hasn't been explicitly enabled.
1280 - Don't disable the mingw32 log window if the logfile directive
1281 isn't used. While it was an intentional change in 3.0.7 at least
1282 one user perceived it as a regression and the same effect can
1283 be achieved by disabling all debug directives.
1284 - Fixed two minor problems related to the win32 build process: a css
1285 file was not being in the installer and the trustfile comment in the
1286 config.txt referenced a nonexisting file
1287 - Minor documentation fixes.
1289 *** Version 3.0.7 Beta ***
1291 - Added zlib support to filter content with gzip and deflate
1292 encoding. (Patch provided by Wil Mahan)
1293 - Dedicated filters and actions are used for header filtering.
1294 "filter-client-headers" and "filter-client-headers" are no longer
1295 supported, use server-header-filter{} and client-header-filter{}
1297 - Tags can be used to change actions based on HTTP headers.
1298 - New server-header filter: less-download-windows.
1299 - New client-header taggers: css-requests, image-requests,
1300 client-ip-address, http-method, allow-post, complete-url,
1301 user-agent and privoxy-control.
1302 - New server-header taggers: content-type and privoxy-control.
1303 - The forward-override{} action allows to change the forwarding
1304 settings through the action files, for example based on client
1305 headers like the User-Agent, or the request origin.
1306 - Socks errors are no longer handled by the CGI page for
1307 DNS resolution failures.
1308 - CGI pages use favicons to signal whether they are error
1309 or control pages. This is useful if you rely heavily on
1311 - The show-url-info CGI page shows the forwarding settings.
1312 - "Crunch!" log messages (used when Privoxy answers requests
1313 by itself) now also contain the reason.
1314 - Allow to rewrite the request destination behind the client's back.
1315 - Fix socks requests on big-endian platforms. Patch provided by Song Weijia.
1316 - Fixes possible deadlocks and crashes on OpenBSD.
1317 Patch provided by Ralf Horstmann.
1318 - The CGI action editor allows to edit actionfiles with previously
1319 forbidden characters like dots.
1320 - New trust entries are saved with a comment that contains the
1321 trusted referring URL (Suggested by Daniel Griscom).
1322 - Filter descriptions are HTML encoded automatically.
1323 - New config option "split-large-forms" to work
1324 around a browser bug that caused IE6 and IE7 to ignore
1325 the Submit button on the edit-actions-for-url CGI page.
1326 - New config option "allow-cgi-request-crunching" to allow
1327 requests for Privoxy's CGI pages to be blocked, redirected
1328 or (un)trusted like ordinary requests.
1329 - Empty filter files no longer interrupt the filtering process
1330 prematurely and are correctly listed on the show-status CGI page.
1331 - New config option "accept-intercepted-requests" to combine
1332 Privoxy with any packet filter to build an intercepting proxy
1333 for HTTP/1.1 requests (and for HTTP/1.0 requests with Host header set).
1334 - fast-redirects{} catch redirects to https URLs as well.
1335 - redirect{s@foo@bar@} can be used to redirect to a rewritten
1336 version of the original URL.
1337 - Trap unsupported gopher proxy requests.
1338 - Fixed a bug in the User Manual delivery on Windows
1339 (mingw32 only). Images now show up correctly and HTML
1340 pages are no longer padded with garbage data.
1341 - Fixed several minor memory leaks, most of them discovered with Valgrind.
1342 - Only unlink the pidfile if it's actually used.
1343 - Retries after connection problems with forced requests
1344 aren't blocked again.
1345 - On Unix SIGABRT causes a core dump as expected and is no
1346 longer treated as normal shutdown signal.
1347 - The "access denied" CGI page is more descriptive and
1348 allows retries to circumvent the referrer check.
1349 - Updated PCRS to handle unexpected PCRE errors properly.
1350 Fixed crashes that could occur if Privoxy was build
1351 with external PCRE versions newer than Privoxy's internal
1352 one. (Reported by Chung-chieh Shan)
1353 - Fixed crashes with null bytes in PCRS replacement strings
1354 (Patch provided by Felix Gröbert).
1355 - Fixed crashes with header time randomization on mingw32.
1356 - The CGI style sheet is no longer delivered if the referring
1357 page isn't a Privoxy CGI page. This prevents a JavaScript-based
1358 Privoxy detection "attack". Note that detecting Privoxy is
1359 still possible through other ways and Privoxy was never intended
1360 to be invisible anyway.
1361 - Added support for AmigaOS 4, fixed build for AmigaOS 3.x.
1362 - The show-url-info CGI page displays a warning if Privoxy
1363 is currently toggled off.
1364 - The show-status CGI page suppresses the edit button
1365 for action files if Privoxy has no write access.
1366 - Most CGI error pages react properly to HEAD requests.
1367 - Requests with RFC 3253 HTTP methods (used by Subversion)
1368 are accepted. (Patch provided by Petr Kadlec)
1369 - New config option "templdir" to change the location
1370 of the CGI templates to make sure customized templates
1372 - Better handling of "HTTP/1.1 100 Continue" responses.
1373 - The background of the PNG pattern is transparent.
1374 - Fixed XML syntax errors caused by banners-by-size and banners-by-url.
1375 - Fixed crashes and possible action file corruptions
1376 when lines containing hashes are written through the CGI editor.
1377 - Supports dynamic filters which can contain variables.
1378 - Supports tags to change the actions based on client or server headers.
1379 - Incorrect actions are logged before program termination.
1380 - The "actionsfile" syntax in the configuration file is consistent
1381 with the rest of the configuration options and requires the
1382 whole file name. This is an incompatible change, if you use
1383 an old configuration file you might have to append ".action"
1384 to your "actionsfile" directives.
1385 - With the configuration file option "enforce-blocks" the
1386 "go there anyway" mechanism can be disabled without recompiling
1388 - More precise error messages in case of incorrect acl syntax.
1389 - Logs a warning if filtering is enabled but impossible due
1390 to lack of zlib support or use of the prevent-compression action.
1391 - Less noisy handling of Cookie:" and "Connection:" headers.
1392 - Improved error messages in case of connection problems.
1393 - Fix a command-line-parsing bug that was introduced before 3.0.5
1394 beta and caused Privoxy to treat the last argument as configuration
1395 file if no configuration file was specified.
1396 - Treat unknown command line options as fatal errors instead
1397 of silently ignoring them.
1398 - Use string functions with length checks more often.
1399 - Don't log CONNECT requests twice.
1400 - Allow to log the source address for ACL-related connection drops.
1401 - Don't ignore applying filters if the server didn't
1402 specify a Content-Type. Bug reported by Amuro Namie.
1403 - Rejected CONNECT requests are logged with log level info
1404 (enabled by default) and the reason for the block.
1405 - New command line option "--pre-chroot-nslookup hostname" to
1406 intialize the resolver library before chroot'ing. On some systems this
1407 reduces the number of files that must be copied into the chroot tree.
1408 (Patch provided by Stephen Gildea)
1409 - Fix a long-standing memory corruption bug that could cause
1410 Privoxy to overwrite a single byte in memory it didn't explicitly
1411 allocate (but that probably was allocated anyway due to bucket size).
1412 - Send template-based CGI pages as HTTP/1.1 unless the client
1414 - Let the first line in connection established responses
1415 end in \r\n as required by RFC1945. Reported by Bert van Leeuwen.
1416 - If no log file has been specified, disable logging instead of logging
1418 - Don't block stderr when in daemon mode.
1419 - Ignore missing zero-chunks when filtering chunk-encoded content.
1420 Earlier Privoxy versions would buffer and then forward the content
1421 unmodified which caused some browsers to simply show empty pages.
1422 - Fix double free in cgi_edit_actions_list(). Reported by Venustech AD-LAB.
1423 - The code to add X-Forwarded-For headers when the hide-forwarded-for-headers
1424 action isn't being used has been removed.
1425 - Fixed trustfile feature which previously didn't work without FEATURE_TOGGLE.
1427 - Minor code clean-ups, filter and action file updates.
1428 (Some of them reported by Davide Alberani, Markus Elfring,
1429 Stefan Huehner and Adam Piggott)
1431 *** Version 3.0.6 ***
1433 - New content filters: no-ping, google, msn, yahoo and blogspot.
1434 - New header filters: x-httpd-php-to-html, html-to-xml, xml-to-html
1435 and hide-tor-exit-notation.
1436 - The special header "X-Filter: No" now disables header filtering as well.
1437 - Improved the filters img-reorder, js-annoyances, webbugs,
1438 banners-by-size, banners-by-link and ie-exploits to make them
1439 less likely to break anything.
1440 - Removed outdated URL patterns in default.action and added new ones.
1441 - Added redirection from http://p.p/user-manual to http://p.p/user-manual/

1451 following new or significantly improved actions (among many
1452 other improvements):
1454 content-type-overwrite{}
1455 crunch-client-header{string}
1456 crunch-if-none-match
1457 crunch-server-header{string}
1458 fast-redirects{check-decoded-url}
1459 filter-client-headers
1460 filter-server-headers
1462 handle-as-empty-document
1463 hide-accept-language{}
1464 hide-content-disposition{}
1465 hide-if-modified-since

1494 - Fixed yet another two memory leaks. Process growth seems stopped now.
1495 - Further tightened security against malicious toggle-off links.
1496 - Excluded text/plain MIME types from filtering. This fixes a
1497 couple of client-crashing, download corruption and
1498 Privoxy performance issues, whose root cause lies in
1499 web servers labelling content of unknown type as text/plain.
1500 - Assorted fixes for POSIX compliance, signal handling, graceful
1501 termination, compiler warnings, OSX support, Win32 systray,
1502 error logging, hostname wildcards, correct detection of NetBSD.
1503 - Workarounds for client (iTunes etc) and server (PHP < 4.2.3) bugs

1521 html-annoyances, content-cookies and fun filters
1522 - Replaced filter "popups" by choice between two modes:
1523 - "unsolicited-popups" tries to catch only the unsolicited ones
1524 - "all-popups" tries to kill them all (as before)
1525 - New filter "tiny-textforms" Help those tiny or hard-wrap textareas.
1526 - New filter "jumping-windows" that prevents windows from resizing
1527 and moving themselves
1528 - New filter "demoronizer" which fixes MS's abuse of std charsets
1529 (common cases anyway).
1530 - Replaced "nimda" with more general "ie-exploits" filter in which
1531 all filters for exploits shall be collected
1532 - Improved cookie logging
1533 - Rewrote make install target. Added uninstall and install-strip

1592 reflected throughout (file locations, etc).
1593 - ijb.action is now default.action. re_filterfile is now

1668 *** Version 2.9.3 pre-Alpha Changes ***
1670 - Amiga support (completely untested by me - I don't have an Amiga)
1671 - "tinygif 3" support (redirects blocked images to a specified URL, so
1672 the browser doesn't have to load and cache many copies of the same
1674 - one case where there were both local and global "referrer" variables
1675 (yuck!) clarified by renaming the local one to "refer".
1676 - Fixed some places where close() was used instead of close_socket().
1677 Thanks to Jörg Strohmayer (joergs at users.sourceforge.net) for these.
1678 - Temporary hack to get FORCE_LOAD to work with IE. I just lowercased the
1679 FORCE_LOAD_PREFIX. Needs fixing properly.
1680 - Most URLs hardcoded into Junkbuster were changed to go through a script
1681 e.g. http://ijbswa.sourceforge.net/redirect.php?v=2.9.3&to=faq
1682 The only other URLs left are the GNU GPL:
1683 http://www.fsf.org/copyleft/gpl.html
1685 http://ijbswa.sourceforge.net/
1686 ... and various URLs which will be intercepted by Junkbuster anyway.
1687 TODO: Still need to do something with the URLs in Junkbuster Corp's
1688 copyright/trademark notice on the bottom of the show-proxy-args page.
1689 - PCRE or GNU Regex is now a #define option.
1692 *** Version 2.9.2 pre-Alpha Changes ***
1694 - Andreas applied the latest version of the FORCE patch.
1697 *** Version 2.9.1 pre-Alpha Changes ***
1699 - in parsers.c, fixed two #ifdef FORCE to #ifdef FORCE_LOAD
1700 (BTW: I think FORCE is precise enough, since loading remote
1701 data is the whole purpose of a proxy..)
1702 - Set the FORCE_PREFIX (back) to 'IJB-FORCE-LOAD-'. While 'noijb.'
1703 is more elegant and looks like a hostname in the URL, it doesn't
1704 make clear to the inexperienced user that the proxy is bypassed. It
1705 also has a higher name collision risk.
1706 - Filled in the function header templates for my functions in
1707 parsers.c (again). They obviously got lost in our current
1709 - Cut the credit for the §-referrer-option from the config file,
1710 that Stefan had placed there.
1711 - Improved the re_filterfile
1714 *** Version 2.9.0 pre-Alpha Changes ***
1716 - Now use PCRE, not GNU REGEX. I have not yet had chance to check the
1717 syntax of the block/image/cookie file to ensure that they match what
1718 is expected - however they seem to work.
1719 - Replaced "configure" script with one generated by "autoconf". Also
1720 use a header "config.h" (was ijbconfig.h in my previous release) for
1721 the #defines. "config.h" is now generated with "autoheader" from
1722 "acconfig.h" and "configure.in". (Note that to install you do not
1723 need autoconf or autoheader - just run "./configure".)
1724 To see command-line options, run "./configure --help".
1725 This is my first ever autoconf script, so it has some rough edges
1726 (how PCRE is handled is the roughest).
1727 - Error logging code replaced with new module errlog.c, based on the
1728 one from JunkbusterMT (but with the threading code removed).
1729 - Most of Rodney's 0.21 and 0.21A patches applied. (Marked *). I did not
1730 apply all of these, since I had already independently done conditional
1731 popup file, conditional image file, and integration of popup code.
1732 - ACL, Jar and trust files conditionally compiled.
1733 - New source file headers.
1734 - Various cosmetic changes. (But I have not consistently ordered the
1735 config files - I think that's worthwhile, but it's 1am and I want to
1737 - RCS tags on .h files.
1738 - RCS tags are const char[] rather than const char *. (Saves 4 bytes
1740 - VC++ project files renamed to vc_junkbuster.*.
1741 - show-proxy-args now shows status of all conditionals, not just REGEX
1742 - Various functions moved around. Most notably all the system-specific
1743 sockets code which was spread between jcc.c, bind.c, and connect.c,
1744 has been moved to "jbsockets.c". The non-system-specific code from
1745 connect.c and socks4.c has been movet to "gateway.c". Also, the
1746 config file loader and the global variables it writes to have been
1747 moved to "loadcfg.c". (Maybe this should go into loaders.c?)
1748 And candidate for the "worst filename ever" award is "miscutil.c",
1749 which contains, well, miscellaneous utility functions like zalloc.
1750 (Suggestions for a better name for this file are welcome!)
1751 - Loaders now use a common function to read a line and skip comments,
1752 and this function also stores the proxy_args.
1753 - Added ./junkbuster --help (Not for Win32 GUI)
1754 - Added ./junkbuster --version (Not for Win32 GUI)
1755 - Win32 resources are now all marked as "U.S. English", rather than
1756 being a mix of "U.S. English", "U.K. English" and "Irish English".
1757 - Version number changes to 2.9.0
