$Id: TODO,v 1.34 2011/02/10 22:18:30 fabiankeil Exp $ Some Privoxy related tasks, sorted by the time they have been added, not by priority. 1) Add some regression tests. Filters should be tested automatically (variables too). Could probably reuse large parts of Privoxy-Filter-Test. 3) Fix some more XXX: comments. 4) Fix some more compiler warnings. (Especially on amd64) Partly done. 6) Remove actions that aren't needed anymore: content-type-overwrite should probably stay as it's also used by some of the CGI pages (XXX: name them). crunch-client-header and crunch-server-header should probably go, their only advantage is that their search strings can be controlled through the CGI pages, other than that they only have disadvantages. crunch-if-none-match can be replaced with a header filter. prevent-compression has a misleading name and could be replaced with a header filter. 7) force-text-mode has a stupid name and should probably be renamed to force-filter-mode. 8) handle-as-empty-document and handle-as-image should be merged to something like handle-as{something} to prevent them from being activated at the same time. 10) There's a bug in the CGI editor that turns the first section's "Insert new section below" into a "Insert new section above" button. 11) CGI templates should use semantically-correct HTML and scale properly. 12) Add pipelining support. 13) Use zlib to deflate content before sending it to the client. Measure if it makes a difference. Update: Note that this is already being worked on and mostly done for buffered content and internal CGI responses. The difference it does make, seems to be that it slows things down if the client and Privoxy are running on the same system, so for most users enabling it will make no sense. 14) Log and filter POST parameters. They can now be logged with the noisy debug 32768, but are still not filtered. 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? 22) Verify action files properly (Including arguments) and act accordingly (should probably intercept all requests with a "Invalid option foo detected" CGI page). 23) Do the same in case of syntax errors in the configuration file, instead of just exiting or ignoring the problem. 25) Handle multiple filters with the same name better. Reject them? 26) Let show-url-info detect clearly invalid URLs. 27) Make errno logging less thread-unsafe. Verify that it's really an improvement. 28) Don't take default ports in case of invalid forwarding ports. 31) If a string action foo is disabled csp->action->string[ACTION_STRING_FOO] doesn't necessarily contain NULL, but may contain the string of an enabled foo action in an overruled section. Is it a bug? Does it matter? 32) In case of forwarding failures with socks port == 9050, show extra info about Tor (the whole FAQ entry?). 35) Do less work in the accept_connection() thread. Partly done. Good enough? 36) Unload unused action files directly, even if they are disabled without replacement. 38) In the final results, explicitly list disabled multi actions with their parameters. Not as trivial as it sounds. 39) Verify loadcfg.c jarfile reloading and friends. /* XXX: Does disabling this actually work? */ 40) Fix core dumping in daemon mode. Introduce a cwd config option? 41) Change documentation framework to one that works cross-platform. Evaluate WML. 42) Add DTrace hooks. Now that FreeBSD has userland DTrace support there's no longer any reason not to. 43) Write a tool to check URL patterns against URLs in the log file. This could be included in Privoxy-Regression-Test. 44) Privoxy-Log-Parser: Consider highlighting "Connection" in: 23:13:03.506 283b6100 Header: Replaced: 'Connection: Keep-Alive' with 'Connection: close' 49) Add FAQ for NTLM proxies. Still necessary? 50) Investigate possible PCRS template speedup when searching macros with strstr() before compiling pcrs commands. 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. 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 pretents to support it, so we could do it independently from 53). 55) Apply for Coverity scans: http://scan.coverity.com/ 56) Apply for the "free online access for qualified open-source software projects" for the Co-Advisor HTTP compliance tests: http://coad.measurement-factory.com/details.html#pricing 57) Allow piping into external programs to allow more powerful filters and policy decisions. Incomplete support available in Fabian's popen branch. 58) Move more template strings from the code into the actual templates. 59) Import the German template translation. 60) Ask the Russian translators for input on how to make their life easier. 61) Consider (optionally?) skipping the hostname comparison when checking if a connections that goes to a HTTP proxy can be reused. Do all HTTP proxy support that? Is it worth it? 63) Reject clearly too large requests earlier? 64) Use proper copyright attribution. "Privoxy Developers" is no legal entity. 65) Polish Website. Probably involves ditching the Docbook mess in favour of wml. There should be already some threads in the mailinglists archives about this. 66) Increase maximum number of action and filter files. 67) Clean up directory layout. Depends on 54 so we don't lose the revision history. 68) Use standard make syntax so we don't depend on GNU make. 69) Update autoconf setup (or move away from it). 70) If the server connection is reset but the headers are received, consider passing the mess to the client instead of showing the connect-failed template. Relates to #2698674. 71) Allow to listen on multiple addresses without having to bind to all. 74) Let Privoxy-Regression-Test optionally check that action sections which disable actions actually are preceded by sections that enable said actions. 75) Create a tool that creates Privoxy action (and filter?) files out of adblock files. Could be implemented as option for url-pattern-translator.pl. 76) Cache DNS responses. Note that this has been requested several times by users, but is not a developer priority. If you care about this, feel free to submit patches. 77) Allow to configure the IP address used in outgoing connections. 78) Allow to optionally use pcre's DFA algorithm. 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. 81) Merge Fabian's unlimited-config-lines branch. 82) Detect if the system time goes back in time let the user know if it caused any connections to get closed. 83) Make the FAQ available through the CGI interface like the user manual is. 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. 86) Add a server-body-tagger action. This is trivial as as all the functionallity required to do it already exists. 87) Add a client-body-tagger action. This is less trivial as we currently don't buffer client bodies. After 14) is implemented it would be trivial, though. 88) Investigate if there's a Perl module that Privoxy-Regression-Test could optionally use to keep connections alive. 89) When multiple block actions apply, consider showing all the block reasons on the blocked page that haven't been overruled, not just the last one. 90) Implement NO-TAG: patterns that enable a section if the provided pattern doesn't match any TAG. This would make some things cleaner.
