+ with a couple of general improvements an new features.</p>
+ <p>Changes in <span class="APPLICATION">Privoxy 3.0.33</span> stable:</p>
<ul>
<li>
- <p>Bug fixes:</p>
-
+ <p>Security/Reliability:</p>
<ul>
<li>
- <p>Client sockets are now properly shutdown and drained before
- being closed. This fixes page truncation issues with clients that
- aggressively pipeline data on platforms that otherwise discard
- already written data. The issue mainly affected Opera users and
- was initially reported by Kevin in #3464439, szotsaki provided
- additional information to track down the cause.</p>
- </li>
-
- <li>
- <p>Fix latency calculation for shared connections (disabled by
- default). It was broken since their introduction in 2009. The
- calculated latency for most connections would be 0 in which case
- the timeout detection failed to account for the real latency.</p>
- </li>
-
- <li>
- <p>Reject URLs with invalid port. Previously they were parsed
- incorrectly and characters between the port number and the first
- slash were silently dropped as shown by curl test 187.</p>
- </li>
-
- <li>
- <p>The default-server-timeout and socket-timeout directives
- accept 0 as valid value.</p>
- </li>
-
- <li>
- <p>Fix a race condition on Windows that could cause Privoxy to
- become unresponsive after toggling it on or off through the
- taskbar icon. Reported by Tim H. in #3525694.</p>
+ <p>cgi_error_no_template(): Encode the template name to prevent XSS (cross-side scripting) when Privoxy is
+ configured to servce the user-manual itself. Commit 0e668e9409c. OVE-20211102-0001. CVE-2021-44543.
+ Reported by: Artem Ivanov</p>
</li>
-
<li>
- <p>Fix the compilation on Windows when configured without IPv6
- support.</p>
+ <p>get_url_spec_param(): Free memory of compiled pattern spec before bailing. Reported by Joshua Rogers
+ (Opera) who also provided the fix. Commit 652b4b7cb0. OVE-20211201-0003. CVE-2021-44540.</p>
</li>
-
<li>
- <p>Fix an assertion that could cause debug builds to abort() in
- case of socks5 connection failures with "debug 2" enabled.</p>
+ <p>process_encrypted_request_headers(): Free header memory when failing to get the request destination.
+ Reported by Joshua Rogers (Opera) who also provided the fix. Commit 0509c58045. OVE-20211201-0002.
+ CVE-2021-44541.</p>
</li>
-
<li>
- <p>Fix an assertion that could cause debug builds to abort() if a
- filter contained nul bytes in the replacement text.</p>
+ <p>send_http_request(): Prevent memory leaks when handling errors Reported by Joshua Rogers (Opera) who
+ also provided the fix. Commit c48d1d6d08. OVE-20211201-0001. CVE-2021-44542.</p>
</li>
</ul>
</li>
-
<li>
- <p>General improvements:</p>
-
+ <p>Bug fixes:</p>
<ul>
<li>
- <p>Significantly improved keep-alive support for both client and
- server connections.</p>
- </li>
-
- <li>
- <p>New debug log level 65536 which logs all actions that were
- applied to the request.</p>
- </li>
-
- <li>
- <p>New directive client-header-order to forward client headers in
- a different order than the one in which they arrived.</p>
- </li>
-
- <li>
- <p>New directive tolerate-pipelining to allow client-side
- pipelining. If enabled (3.0.20 beta enables it by default),
- Privoxy will keep pipelined client requests around to deal with
- them once the current request has been served.</p>
- </li>
-
- <li>
- <p>New --config-test option to let Privoxy exit after checking
- whether or not the configuration seems valid. The limitations
- noted in TODO #22 and #23 still apply. Based on a patch by
- Ramkumar Chinchani.</p>
- </li>
-
- <li>
- <p>New limit-cookie-lifetime{} action to let cookies expire
- before the end of the session. Suggested by Rick Sykes in
- #1049575.</p>
- </li>
-
- <li>
- <p>Increase the hard-coded maximum number of actions and filter
- files from 10 to 30 (each). It doesn't significantly affect
- Privoxy's memory usage and recompiling wasn't an option for all
- Privoxy users that reached the limit.</p>
- </li>
-
- <li>
- <p>Add support for chunk-encoded client request bodies.
- Previously chunk-encoded request bodies weren't guaranteed to be
- forwarded correctly, so this can also be considered a bug fix
- although chunk-encoded request bodies aren't commonly used in the
- real world.</p>
- </li>
-
- <li>
- <p>Add support for Tor's optimistic-data SOCKS extension, which
- can reduce the latency for requests on newly created connections.
- Currently only the headers are sent optimistically and only if
- the client request has already been read completely which rules
- out requests with large bodies.</p>
- </li>
-
- <li>
- <p>After preventing the client from pipelining, don't signal
- keep-alive intentions. When looking at the response headers
- alone, it previously wasn't obvious from the client's perspective
- that no additional responses should be expected.</p>
- </li>
-
- <li>
- <p>Stop considering client sockets tainted after receiving a
- request with body. It hasn't been necessary for a while now and
- unnecessarily causes test failures when using curl's test
- suite.</p>
- </li>
-
- <li>
- <p>Allow HTTP/1.0 clients to signal interest in keep-alive
- through the Proxy-Connection header. While such client are rare
- in the real world, it doesn't hurt and couple of curl tests rely
- on it.</p>
- </li>
-
- <li>
- <p>Only remove duplicated Content-Type headers when filters are
- enabled. If they are not it doesn't cause ill effects and the
- user might not want it. Downgrade the removal message to
- LOG_LEVEL_HEADER to clarify that it's not an error in Privoxy and
- is unlikely to cause any problems in general. Anonymously
- reported in #3599335.</p>
- </li>
-
- <li>
- <p>Set the socket option SO_LINGER for the client socket.</p>
- </li>
-
- <li>
- <p>Move several variable declarations to the beginning of their
- code block. It's required when compiling with gcc 2.95 which is
- still used on some platforms. Initial patch submitted by Simon
- South in #3564815.</p>
- </li>
-
- <li>
- <p>Optionally try to sanity-check strptime() results before
- trusting them. Broken strptime() implementations have caused
- problems in the past and the most recent offender seems to be
- FreeBSD's libc (standards/173421).</p>
+ <p>handle_established_connection(): Skip the poll()/select() calls if TLS data is pending on the server
+ socket. The TLS library may have already consumed all the data from the server response in which case
+ poll() and select() will not detect that data is available to be read. Fixes SF bug #926 reported by Wen
+ Yue.</p>
</li>
-
<li>
- <p>When filtering is enabled, let Range headers pass if the range
- starts at the beginning. This should work around (or at least
- reduce) the video playback issues with various Apple clients as
- reported by Duc in #3426305.</p>
+ <p>continue_https_chat(): Update csp->server_connection.request_sent after sending the request to make
+ sure the latency is calculated correctly. Previously https connections were not reused after timeout
+ seconds after the first request made on the connection.</p>
</li>
-
<li>
- <p>Do not confuse a client hanging up with a connection time out.
- If a client closes its side of the connection without sending a
- request line, do not send the CLIENT_CONNECTION_TIMEOUT_RESPONSE,
- but report the condition properly.</p>
+ <p>free_pattern_spec(): Don't try to free an invalid pointer when unloading an action file with a TAG
+ pattern while Privoxy has been compiled without FEATURE_PCRE_HOST_PATTERNS. Closes: SF patch request #147.
+ Patch by Maxim Antonov.</p>
</li>
-
<li>
- <p>Allow closing curly braces as part of action values as long as
- they are escaped.</p>
+ <p>Adjust build_request_line() to create a CONNECT request line when https-inspecting and forwarding to a
+ HTTP proxy. Fixes SF bug #925 reported by Wen Yue.</p>
</li>
-
<li>
- <p>On Windows, the logfile is now written before showing the GUI
- error message which blocks until the user acknowledges it.
- Reported by Adriaan in #3593603.</p>
+ <p>load_config(): Add a space that was missing in a log message.</p>
</li>
-
<li>
- <p>Remove an unreasonable parameter limit in the CGI interface.
- The new parameter limit depends on the memory available and is
- currently unlikely to be reachable, due to other limits in both
- Privoxy and common clients. Reported by Andrew on
- ijbswa-users@.</p>
+ <p>read_http_request_body(): Fix two error messages that used an incorrect variable.</p>
</li>
-
<li>
- <p>Decrease the chances of parse failures after requests with
- unsupported methods were sent to the CGI interface.</p>
+ <p>If the the response is chunk-encoded, ignore the Content-Length header sent by the server. Allows to
+ load https://redmine.lighttpd.net/ with filtering enabled.</p>
</li>
</ul>
</li>
-
<li>
- <p>Action file improvements:</p>
-
+ <p>General improvements:</p>
<ul>
<li>
- <p>Remove the comment that indicated that updated default.action
- versions are released on their own.</p>
- </li>
-
- <li>
- <p>Block 'optimize.indieclick.com/' and
- 'optimized-by.rubiconproject.com/'</p>
+ <p>Allow to edit the add-header action through the CGI editor by generalizing the code that got added with
+ the suppress-tag action. Closes SF patch request #146. Patch by Maxim Antonov.</p>
</li>
-
<li>
- <p>Unblock 'adjamblog.wordpress.com/' and
- 'adjamblog.files.wordpress.com/'. Reported by Ryan Farmer in
- #3496116.</p>
+ <p>Add a CGI handler for /wpad.dat that returns a Proxy Auto-Configuration (PAC) file. Among other things,
+ it can be used to instruct clients through DHCP to use Privoxy as proxy. For example with the dnsmasq
+ option: dhcp-option=252,http://config.privoxy.org/wpad.dat Initial patch by Richard Schneidt.</p>
</li>
-
<li>
- <p>Unblock '/.*Bugtracker'. Reported by pwhk in #3522341.</p>
+ <p>Don't log the applied actions in process_encrypted_request() Log them in continue_https_chat() instead
+ to mirror chat(). Prevents the applied actions from getting logged twice for the first request on an
+ https-inspected connection.</p>
</li>
-
<li>
- <p>Add test URLs for '.freebsd.org' and '.watson.org'.</p>
+ <p>OpenSSL generate_host_certificate(): Use config.privoxy.org as Common Name Org and Org Unit if the real
+ host name is too long to get accepted by OpenSSL. Clients should only care about the Subject Alternative
+ Name anyway and we can continue to use the real host name for it. Reported by Miles Wen on
+ privoxy-users@.</p>
</li>
-
<li>
- <p>Unblock '.urbandictionary.com/popular'.</p>
+ <p>Establish the TLS connection with the client earlier and decide how to route the request afterwards.
+ This allows to change the forwarding settings based on information from the https-inspected request, for
+ example the path.</p>
</li>
-
<li>
- <p>Block '.adnxs.com/'.</p>
+ <p>listen_loop(): When shutting down gracefully, close listening ports before waiting for the threads to
+ exit. Allows to start a second Privoxy with the same config file while the first Privoxy is still
+ running.</p>
</li>
-
<li>
- <p>Block 'farm.plista.com/widgetdata.php'.</p>
+ <p>serve(): Close the client socket as well if the server socket for an inspected connection has been
+ closed. Privoxy currently can't establish a new server connection when the client socket is reused and
+ would drop the connection in continue_https_chat() anyway.</p>
</li>
-
<li>
- <p>Block 'rotation.linuxnewmedia.com/'.</p>
+ <p>Don't disable redirect checkers in redirect_url(). Disable them in handle_established_connection()
+ instead. Doing it in redirect_url() prevented the +redirect{} and +fast-redirects{} actions from being
+ logged with LOG_LEVEL_ACTIONS.</p>
</li>
-
<li>
- <p>Block 'reklamy.sfd.pl/'. Reported by kacperdominik in
- #3399948.</p>
+ <p>handle_established_connection(): Slightly improve a comment.</p>
</li>
-
<li>

<li>
- <p>Unblock 'websupport.wdc.com/'. Reported by Adam Piggot in
- #3577851.</p>
+ <p>socks5_connect(): Fix indentation.</p>

- <p>Block '/openx/www/delivery/'.</p>
+ <p>handle_established_connection(): Improve an error message.</p>
</li>
-
<li>
- <p>Disable fast-redirects for '.googleapis.com/'.</p>
+ <p>create_pattern_spec(): Fix ifdef indentation.</p>
</li>
-
<li>
- <p>Block 'imp.double.net/'. Reported by David Bo in #3070411.</p>
+ <p>Fix comment typos.</p>
</li>
-
<li>
- <p>Block 'gm-link.com/' which is used for email tracking.
- Reported by David Bo in #1812733.</p>
+ <p>process_encrypted_request(): Improve a log message. The function only processes request headers and
+ there may still be unread request body data left to process.</p>
</li>
-
<li>
- <p>Verify that requests to "bwp." are blocked. URL taken from
- #1736879 submitted by Francois Marier.</p>
+ <p>chat(): Log the applied actions before deciding how to forward the request.</p>
</li>
-
<li>
- <p>Block '/.*bannerid='. Reported by Adam Piggott in
- #2975779.</p>
+ <p>parse_time_header(): Silence a coverity complaint when building without assertions.</p>
</li>
-
<li>
- <p>Block 'cltomedia.info/delivery/' and '.adexprt.com/'.
- Anonymously reported in #2965254.</p>
+ <p>receive_encrypted_request_headers(): Improve a log message.</p>
</li>
-
<li>
- <p>Block 'de17a.com/'. Reported by David Bo in #3061472.</p>
+ <p>mbedTLS get_ciphersuites_from_string(): Use strlcpy() instead of strncpy(). Previously the terminating
+ NUL wasn't copied which resulted in a compiler warning. This didn't cause actual problems as the target
+ buffer was initialized by zalloc_or_die() so the last byte of the target buffer was NUL already. Actually
+ copying the terminating NUL seems clearer, though.</p>
</li>
-
<li>
- <p>Block 'oskar.tradera.com/'. Reported by David Bo in
- #3060596.</p>
+ <p>Remove compiler warnings. "log_error(LOG_LEVEL_FATAL, ..." doesn't return but apparently the compiler
+ doesn't know that. Get rid of several "this statement may fall through [-Wimplicit-fallthrough=]"
+ warnings.</p>
</li>
-
<li>
- <p>Block '/scripts/webtrends\.js'. Reported by johnd16 in
- #3002729.</p>
+ <p>Store the PEM certificate in a dynamically allocated buffer when https-inspecting. Should prevent errors
+ like: 2021-03-16 22:36:19.148 7f47bbfff700 Error: X509 PEM cert len 16694 is larger than buffer len 16383
+ As a bonus it should slightly reduce the memory usage as most certificates are smaller than the previously
+ used fixed buffer. Reported by: Wen Yue</p>
</li>
-
<li>
- <p>Block requests for 'pool.*.adhese.com/'. Reported by johnd16
- in #3002716.</p>

- <p>When stopping to watch a client socket due to pipelining,
- additionally log the socket number.</p>
- </li>
-
- <li>
- <p>Log the client socket and its condition before closing it.
- This makes it more obvious that the socket actually gets closed
- and should help when diagnosing problems like #3464439.</p>
- </li>
-
- <li>
- <p>In case of SOCKS5 failures, do not explicitly log the server's
- response. It hasn't helped so far and the response can already be
- logged by enabling "debug 32768" anyway. This reverts v1.81 and
- the follow-up bug fix v1.84.</p>
- </li>
-
- <li>
- <p>Relocate the connection-accepted message from listen_loop() to
- serve(). This way it's printed by the thread that is actually
- serving the connection which is nice when grepping for thread ids
- in log files.</p>
+ <p>Remove duplicated word in a comment.</p>
</li>
</ul>
</li>
-
<li>
- <p>Code cleanups:</p>
-
+ <p>regression-tests.action:</p>
<ul>
<li>
- <p>Remove compatibility layer for versions prior to 3.0 since it
- has been obsolete for more than 10 years now.</p>
- </li>
-
- <li>
- <p>Remove the ijb_isupper() and ijb_tolower() macros from
- parsers.c since they aren't used in this file.</p>
- </li>
-
- <li>
- <p>Removed the 'Functions declared include:' comment sections
- since they tend to be incomplete, incorrect and out of date and
- the benefit seems questionable.</p>
- </li>
-
- <li>
- <p>Various comment grammar and comprehensibility
- improvements.</p>
- </li>
-
- <li>
- <p>Remove a pointless fflush() call in chat(). Flushing all
- streams pretty much all the time for no obvious reason is
- ridiculous.</p>
- </li>
-
- <li>
- <p>Relocate ijb_isupper()'s definition to project.h and get the
- ijb_tolower() definition from there, too.</p>
- </li>
-
- <li>
- <p>Relocate ijb_isdigit()'s definition to project.h.</p>
- </li>
-
- <li>
- <p>Rename ijb_foo macros to privoxy_foo.</p>
- </li>
-
- <li>
- <p>Add malloc_or_die() which will allow to simplify code paths
- where malloc() failures don't need to be handled gracefully.</p>
- </li>
-
- <li>
- <p>Add strdup_or_die() which will allow to simplify code paths
- where strdup() failures don't need to be handled gracefully.</p>
- </li>
-
- <li>
- <p>Replace strdup() calls with strdup_or_die() calls where it's
- safe and simplifies the code.</p>
- </li>
-
- <li>
- <p>Fix white-space around parentheses.</p>
- </li>
-
- <li>
- <p>Add missing white-space behind if's and the following
- parentheses.</p>
+ <p>Add fetch test for http://p.p/wpad.dat.</p>
</li>
-
<li>
- <p>Unwrap a memcpy() call in resolve_hostname_to_ip().</p>
+ <p>Bump for-privoxy-version to 3.0.33 which introduced the wpad.dat support.</p>
</li>
-
<li>
- <p>Declare pcrs_get_delimiter()'s delimiters[] static const.</p>
+ <p>Add more tests for the '/send-banner' code.</p>
</li>
-
<li>
- <p>Various optimisations to remove dead code and merge
- inefficient code structures for improved clarity, performance or
- code compactness.</p>
+ <p>Add test for OVE-20210203-0001.</p>
</li>
-
<li>
- <p>Various data type corrections.</p>
+ <p>Add a test for CVE-2021-20217.</p>
</li>
-
- <li>
- <p>Change visibility of several code segments when compiling
- without FEATURE_CONNECTION_KEEP_ALIVE enabled for clarity.</p>
- </li>
-
- <li>
- <p>In pcrs_get_delimiter(), do not use delimiters outside the
- ASCII range. Fixes a clang complaint.</p>
- </li>
-
- <li>
- <p>Fix an error message in get_last_url() nobody is supposed to
- see. Reported by Matthew Fischer in #3507301.</p>
- </li>
-
- <li>
- <p>Fix a typo in the no-zlib-support complaint. Patch submitted
- by Matthew Fischer in #3507304.</p>
- </li>
-
- <li>
- <p>Shorten ssplit()'s prototype by removing the last two
- arguments. We always want to skip empty fields and ignore leading
- delimiters, so having parameters for this only complicates the
- API.</p>
- </li>
-
- <li>
- <p>Use an enum for the type of the action value.</p>
- </li>
-
- <li>
- <p>Rename action_name's member takes_value to value_type as it
- isn't used as boolean.</p>
- </li>
-
- <li>
- <p>Turn family mismatches in match_sockaddr() into fatal
- errors.</p>
- </li>
-
- <li>
- <p>Let enlist_unique_header() verify that the caller didn't pass
- a header containing either \r or \n.</p>
- </li>
-
+ </ul>
+ </li>
+ <li>
+ <p>uagen:</p>
+ <ul>
<li>
- <p>Change the hashes used in load_config() to unsigned int.
- That's what hash_string() actually returns and using a
- potentially larger type is at best useless.</p>
+ <p>Bump generated Firefox version to 91 (ESR).</p>
</li>
-
<li>
- <p>Use privoxy_tolower() instead of vanilla tolower() with manual
- casting of the argument.</p>
+ <p>Bump version to 1.2.3.</p>
</li>
-
<li>
- <p>Catch ssplit() failures in parse_cgi_parameters().</p>
+ <p>Bump copyright.</p>

<li>
- <p>Privoxy-Regression-Test:</p>
-
+ <p>Build system:</p>
<ul>
<li>
- <p>Add an 'Overwrite condition' directive to skip any matching
- tests before it. As it has a global scope, using it is more
- convenient than clowning around with the Ignore directive.</p>
+ <p>configure: Bump SOURCE_DATE_EPOCH.</p>
</li>
-
<li>
- <p>Log to STDOUT instead of STDERR.</p>
+ <p>GNUmakefile.in: Fix typo.</p>
</li>
-
<li>
- <p>Include the Privoxy version in the output.</p>
+ <p>configure: Add another warning in case --disable-pthread is used while POSIX threads are available.
+ Various features don't even compile when not using threads.</p>
</li>
-
<li>
- <p>Various grammar and spelling corrections in documentation and
- code.</p>
+ <p>Add configure option to enable MemorySanitizer.</p>
</li>
-
<li>
- <p>Additional tests for range requests with filtering
- enabled.</p>
+ <p>Add configure option to enable UndefinedBehaviorSanitizer.</p>
</li>
-
<li>
- <p>Tests with mostly invalid range request.</p>
+ <p>Add configure option to enable AddressSanitizer.</p>
</li>
-
<li>
- <p>Add a couple of hide-if-modified-since{} tests with different
- date formats.</p>
+ <p>Bump copyright.</p>
</li>
-
<li>
- <p>Cleaned up the format of the regression-tests.action file to
- match the format of default.action.</p>
+ <p>Add a configure option to disable pcre JIT compilation. While JIT compilation makes filtering faster it
+ can cause false-positive valgrind complaints. As reported by Gwyn Ciesla in SF bug 924 it also can cause
+ problems when the SELinux policy does not grant Privoxy "execmem" privileges.</p>
</li>
-
<li>
- <p>Remove the "Copyright" line from print_version(). When using
- --help, every line of screen space matters and thus shouldn't be
- wasted on things the user doesn't care about.</p>
+ <p>configure: Remove obsolete RPM_BASE check.</p>
</li>
</ul>
</li>
-
<li>
- <p>Privoxy-Log-Parser:</p>
-
+ <p>Windows build system:</p>
<ul>
<li>
- <p>Improve the --statistics performance by skipping sanity checks
- for input that shouldn't affect the results anyway. Add a
- --strict-checks option that enables some of the checks again,
- just in case anybody cares.</p>
- </li>
-
- <li>
- <p>The distribution of client requests per connection is included
- in the --statistic output.</p>
+ <p>Update the build script to use mbed tls version 2.6.11.</p>
</li>
-
<li>
- <p>The --accept-unknown-messages option has been removed and the
- behavior is now the default.</p>
+ <p>Update build script to use the final 8.45 pcre library.</p>
</li>
-
<li>
- <p>Accept and (mostly) highlight new log messages introduced with
- Privoxy 3.0.20.</p>
+ <p>Put all the '--enable-xxx' options in the configure call together.</p>
</li>
</ul>
</li>
-
<li>
- <p>uagen:</p>
-
+ <p>macOS build system:</p>
<ul>
<li>
- <p>Bump generated Firefox version to 17.</p>
+ <p>The OSXPackageBuilder repository has been updated and can be used to create macOS packages again.</p>
</li>
</ul>
</li>
-
<li>
- <p>GNUmakefile improvements:</p>
-
+ <p>Documentation:</p>
<ul>
<li>
- <p>The dok-tidy target no longer taints documents with a
- tidy-mark</p>
+ <p>contacting: Remove obsolete reference to announce.sgml.</p>
</li>
-
<li>
- <p>Change RA_MODE from 0664 to 0644. Suggested by Markus Dittrich
- in #3505445.</p>
+ <p>contacting: Request that the browser cache is cleared before producing a log file for submission.</p>
</li>
-
<li>
- <p>Remove tidy's clean flag as it changes the scope of
- attributes. Link-specific colors end up being applied to all
- text. Reported by Adam Piggott in #3569551.</p>
+ <p>Sponsor FAQ: Note that Privoxy users may follow sponsor links without Referer header set.</p>
</li>
-
<li>
- <p>Leave it up to the user whether or not smart tags are
- inserted.</p>
+ <p>newfeatures: Clarify that https inspection also allows to filter https responses.</p>
</li>
-
<li>
- <p>Let w3m itself do the line wrapping for the config file. It
- works better than fmt as it can honour pre tags causing less
- unintentional line breaks.</p>
+ <p>developer-manual: Mention that announce.txt should be updated when doing a release.</p>
</li>
-
<li>
- <p>Ditch a pointless '-r' passed to rm to delete files.</p>
+ <p>config: Explicitly mention that the CGI pages disclosing the ca-password can be blocked and upgrade the
+ disclosure paragraphs to a warning.</p>
</li>
-
<li>
- <p>The config-file target now requires less manual intervention
- and updates the original config.</p>
+ <p>Put all the requested debug options in the config file. Section 11.1 of the Privoxy user manual lists
+ all the debug options that should be enabled when reporting problems or requesting support. Make it easier
+ for users to do the right thing by having all those options present in the config.</p>
</li>
-
<li>
- <p>Change WDUMP to generate ASCII. Add WDUMP_UTF8 to allow UTF-8
- in the AUTHORS file so the names are right.</p>
+ <p>Update TODO list item #184 to note that WolfSSL support will (hopefully) appear after the 3.0.34
+ release.</p>
</li>
-
<li>
- <p>Stop pretending that lynx and links are supported for the
- documentation.</p>
+ <p>Update max-client-connections's description. On modern systems other than Windows Privoxy should use
+ poll() in which case the FD_SETSIZE value isn't releveant.</p>
</li>
- </ul>
- </li>
-
- <li>
- <p>configure improvements:</p>
-
- <ul>
<li>
- <p>On Haiku, do not pass -lpthread to the compiler. Haiku's
- pthreads implementation is contained in its system library,
- libroot, so no additional library needs to be searched. Patch
- submitted by Simon South in #3564815.</p>
+ <p>Add a warning that the socket-timeout does not apply to operations done by TLS libraries.</p>
</li>
-
<li>
- <p>Additional Haiku-specific improvements. Disable checks
- intended for multi-user systems as Haiku is presently
- single-user. Group Haiku-specific settings in their own section,
- following the pattern for Solaris, OS/2 and AmigaOS. Add
- additional library-related settings to remove the need for
- providing configure with custom LDFLAGS. Submitted by Simon South
- in #3574538.</p>
+ <p>Make documentation slightly less "offensive" for some people by avoiding the word "hell".</p>
