Some Privoxy-related tasks, sorted by the time they
have been added, not by priority.
The latest version should be available at:

There's work in progress to fund development on these items using
donations. If you want to donate, please have a look at:

1) Add more regression tests. Filters should be tested automatically
(variables too). Could probably reuse large parts of Privoxy-Filter-Test.
Note that there is currently work in progress to leverage curl's
test suite, patches have been submitted upstream:

+ https://curl.se/mail/lib-2014-06/0070.html
3) Fix some more XXX: comments.
11) CGI templates should use semantically-correct HTML
and scale properly.
+ Work in progress.
+
12) Support pipelining for outgoing connections.
14) Allow to filter POST parameters.
-15) If trusted CGI pages are requested without trusted referrer,
- set the status code to 403 instead of 200.
-
-16) Filter SSL encrypted content as well.
-
- At the beginning we could use a unencrypted connection between
- client and Privoxy, and use an encrypted connection between
- Privoxy and the server.
-
- This should be good enough for most of the content the
- user would want to filter.
-
19) enable-forward-fallback. Syntax? Suggested by K.R.
21) User Manual delivery doesn't accept multiple slashes. Should it?
Figure out a way to solve this. Introduce a cwd config option?
41) Change documentation framework to one that works cross-platform.
- Evaluate WML.
+ Evaluate WML and txt2tags.
42) Add a DTrace USDT provider. Now that FreeBSD has userland DTrace
support there's no longer any reason not to.

Investigated, needs some restructuring but is probably worth it.
-51) Make user-manual directive more generic to allow serving
- the FAQ and other stuff, too. Consider changing the port
- for "same origin policy" issues.

53) Find a more reliable hoster. Involves finding out what our
requirements are and which SF alternatives fulfil them.
It would probably also make sense to look into what other
projects did when migrating away from SF.

+ 2014-05: Work in progress. Hosting wish list at the end
+ of this file. Looks like most of the other projects
+ that left SF had lower standards and moved to hosters
+ that don't come close to sattisfying the requirements.
+ 2016-03: The website has been moved away from SF infrastructure
+ and is also available through https:// now.
+ 2016-04: Server rent for a year has been sponsored by ChameleonJohn.

Interested donors: 1.
-54) Move away from CVS to a more modern revision control system.
- Find out if there are any objection against going with Git.
- Using Git would also have the advantage that SF now pretends
- to support it, so we could do it independently from 53).
-
58) Move more template strings from the code into the actual templates.
59) Import the German template translation.

65) Polish Website. Probably involves ditching the Docbook

+ archives about this. See also #41.
66) Stop hard-coding the number of action and filter files.
-67) Clean up source code directory layout. Depends on 54 so
- we don't lose the revision history.
+67) Clean up source code directory layout.
68) Use standard make syntax so we don't depend on GNU make.
69) Update autoconf setup (or move away from it).
+ Unfortunately the autoconf files can't be simply updated
+ due to license issues:
+ https://lists.privoxy.org/pipermail/privoxy-devel/2016-April/000008.html
70) If the server connection is reset but the headers are
received, consider passing the mess to the client instead
79) Evaluate pcre alternatives.
-80) Change FEATURE_EXTENDED_HOST_PATTERNS to support both
- extended and vanilla host patterns at the same time.
-
- Note that the requirement is to allow the user to decide
- if the domain pattern should be interpreted as regex or
- traditional host pattern and if it's not obvious that the
- user made any decision, default to the latter.
-
- Possible solutions would be:
-
- 1. An always-use-regex-domain-patterns config option
- 2. An enable-regex-domain-patterns-for-this-action-file option
- 3. An enable-regex-domain-patterns-for-this-action-file-until-the-user-says-otherwise option
- 4. A treat-the-domain-pattern-in-this-line-as-regex(-or-not) option
- 5. Combinations of the options above
-
- With 2+4, 3+4 or 2+3+4 being the preferences until
- further discussion.
-
82) Detect if the system time goes back in time let the user
know if it caused any connections to get closed.
-84) Flesh out the user-manual delivery to serve pages from
- other directories, too.
-
-85) Once #84 is done, write a script that populates a directory with

various common third-party icons (stumbleupon.png, facebook.png ...)
and redirect requests for them to Privoxy.
that makes sense. Like #93, this could be useful as a workaround
for misconfigured setups.
-95) Support a non-standard client header in CONNECT requests that
- contains the URL of the requested resource, which is then treated
- like the request URL.
-
- This way the client could opt-in for path-based blocking of https
- requests. Given that the headers from the CONNECT request aren't
- forwarded to the destination server, an unencrypted URL should be
- acceptable if the client and Privoxy are running on the same system
- or in a trusted environment.
-
96) Filters should be easier to look up. Currently get_filter() has to
go through all filters and skip the filter types the caller isn't
interested in.
-98) When showing action section on the CGI pages, properly escape
+98) When showing action sections on the CGI pages, properly escape
line breaks so they can be copy&pasted into action files without
adjustments.
100) Create a cross-platform Privoxy control program and retire
the win32 GUI. Integrate support for Privoxy-Regression-Test,
Privoxy-Log-Parser, Privoxy-Filter-Test, uagen and similar tools.
+ Interested donors: 1.
102) Add an include directive to split the config file into several parts.
files, but only in w32log.c the tray icon is explicitly set.
The logging is inconsistent as well. For details see #3525694.
-105) Add support for socks authentication.
-
106) actionlist.h should be embedded in a way that causes less text
segment bloat.
118) There should be "escaped" dynamic variables that are guaranteed
not to break filters.
-119) Evaluate using pcre's jit mode.
-
120) Add an option to limit pcre's recursion limit below the default.
On some platforms the recursion limit doesn't prevent pcre from
running out of stack space, causing the kernel to kill Privoxy
ungracefully.
-121) Add HTTP/2 support. As a first step, incomming HTTP/1.x requests
+121) Add HTTP/2 support. As a first step, incoming HTTP/1.x requests
should be translated to outgoing HTTP/2 requests where possible
(and if desired by the user).
+ Interested donors: 1.
122) Allow customized log messages.
-123) Evaluate if the voluntarily-disclose-session-keys option in Firefox
- (and other browsers) can be leveraged. Probably depends on #16.
-
124) Add support for the "lightweight OS capability and sandbox framework"
Capsicum. http://www.cl.cam.ac.uk/research/security/capsicum/
Interested donors: 1.
126) Run the Co-Advisor HTTP compliance tests, evaluate the results,
fix the compliance issues that aren't by design and document
the rest.

an action so the behaviour can be enabled on a per-request basis.

134) Track the total number of bytes written to and received from a socket.
but making the reporting mechanism available again would be a
good idea.
+140) Toggling Privoxy off currently also disables stuff that
+ probably shouldn't be affected (such as actions like
+ forward-override). Investigate and fix or document.
+
+142) Remove or update the "internal" pcre version.
+
+143) Add support for OpenBSD's pledge feature once it's stablelized.
+ This should be a lot less work then #124.
+
+146) Allow to save the internal client tag state to disk and
+ load it after restarts.
+
+147) Improve "Building from Source" section in the user manual.
+ A common problem seems to be that it's not obvious to non-technical
+ users how the listed dependencies can be installed on the commonly
+ used platforms. Adding a couple of examples should also be useful for
+ technical users (like Privoxy developers) who want to install or test
+ Privoxy on platforms they are not familiar with.
+
+148) Add a config directive to change the CGI_SITE_2_HOST
+ (default: config.privoxy.org).
+
+ If Privoxy is used as reverse proxy or intercepting proxy without
+ getting intercepted requests, error pages created from default templates
+ currently can result in client requests to config.privoxy.org on the
+ Internet which may not be desirable.
+
+150) Add blacklistd support.
+
+151) Let the dok-tidy target work cross-platform without introducing
+ a ton of white-space changes that hide the content changes.
+
+152) Fix CSS references in the website documentation.
+ For many pages p_doc.css is specified twice using different paths.
+ Usually at least one works, but not all of them do and the
+ duplicated requests are pointless even if they don't end up with
+ a 404.
+
+153) Catch SIGINT and use it to close the listen socket, serve
+ remaining connections and shut down. This would allow higher
+ uptime and make testing more convenient.
+
+154) Underline links in docs and cgi pages. More precisely,
+ don't mess with the browser defaults for link underlining.
+
+155) The sig_handler() shouldn't call log_error().
+ While it isn't known to cause actual problems in normal operation,
+ it's technically incorrect and causes crashes when running in
+ valgrind.
+
+156) Reject socks requests with an explicit error message similar
+ to the one used for ftp. Motivation:
+ https://lists.privoxy.org/pipermail/privoxy-users/2017-March/000195.html
+
+158) Use a single thread to wait for new requests on reused client connections.
+ Currently the thread that handles the first request on a connection
+ stays responsible for the client connect until it gets closed.
+ In case of lots of idle connections lots of waiting threads are used.
+ While it's conceivable that this ineffiency is irrelevant from a
+ performance point of view, using a single thread should reduce Privoxy's
+ memory footprint a bit which may be noticeable in case of multi-user setups
+ with hundreds of idle connections.
+
+161) Properly support requests with chunked transfer-encoding with https inspection.
+
+162) When https inspecting, delete generated keys and certificates if
+ the connection to the destination could not be established.
+ Makes silly DoS attacks slightly more complicated.
+
+163) Use subdirectories in the certificate-directory to lower the number
+ of files per directory.
+
+164) Evaluate switching from pcreposix(3) to pcre's native api
+ for URL matching which allows to compile the patterns once
+ at load-time.
+
+165) Add a max-connections-per-client directive.
+
+166) Figure out how to ship Windows binaries with external libraries
+ like pcre and MbedTLS. Required for #142. Somewhat related:
+ https://lists.privoxy.org/pipermail/privoxy-devel/2020-November/000400.html
+
+167) Set up a public Privoxy-Filter-Test instance.
+
+168) Add a privacy policy.
+
+169) Preserve all relevant copyright and license statements in binary
+ packages we distribute.
