hacking public-inbox -------------------- Send all patches and "git request-pull"-formatted emails to our self-hosting inbox at email@example.com It is archived at: https://public-inbox.org/meta/ and http://hjrcffqmbrq6wope.onion/meta/ (using Tor) Contributions are email-driven, just like contributing to git itself or the Linux kernel; however anonymous and pseudonymous contributions will always be welcome. Please consider our goals in mind: Decentralization, Accessibility, Compatibility, Performance These goals apply to everyone: users viewing over the web or NNTP, sysadmins running public-inbox, and other hackers working public-inbox. We will reject any feature which advocates or contributes to any particular instance of a public-inbox becoming a single point of failure. Things we've considered but rejected include: * exposing article serial numbers outside of NNTP * allowing readers to inject metadata (e.g. votes) We care about being accessible to folks with vision problems and/or lack the computing resources to view so-called "modern" websites. This includes folks on slow connections and ancient browsers which may be too difficult to upgrade due to resource demands. Only depend on Free Software packages which exist in the "main" section of Debian "stable" distribution. That is Debian 9.x ("stretch") as of this writing, but "oldstable" (8.x, "jessie") remains supported for v1 inboxes. In general, we favor mature and well-tested old things rather than the shiny new. Avoid relying on compiled modules too much. Even if it is Free, compiled code makes packages more expensive to audit, build, distribute and verify. public-inbox itself will only be implemented in scripting languages (currently Perl 5) and optional JIT-compiled C (via Inline::C) Do not recurse on user-supplied data. Neither Perl or C handle deep recursion gracefully. See lib/PublicInbox/SearchThread.pm and lib/PublicInbox/MsgIter.pm for examples of non-recursive alternatives to previously-recursive algorithms. Performance should be reasonably good for server administrators, too, and we will sacrifice features to achieve predictable performance. Encouraging folks to self-host will be easier with lower hardware requirements. See design_www.txt and design_notes.txt in the Documentation/ directory for design decisions made during development. See Documentation/technical/ in the source tree for more details on specific topics, in particular data_structures.txt Faster tests ------------ The `make test' target provided by MakeMaker does not run in parallel. Our `make check' target supports parallel runs, and it also creates a `.prove' file to optimize `make check-run'. The prove(1) command (distributed with Perl) may also be used for finer-grained testing: prove -bvw t/foo.t If using a make(1) (e.g. GNU make) with `include' support, the `config.mak' Makefile snippet can be used to set environment variables such as PERL_INLINE_DIRECTORY and TMPDIR. With PERL_INLINE_DIRECTORY set to enable Inline::C support and TMPDIR pointed to a tmpfs(5) mount, `make check-run' takes 6-10s (load-dependent) on a busy workstation built in 2010. Perl notes ---------- * \w, \s, \d character classes all match Unicode characters; so write out class ranges (e.g "[0-9]") if you only intend to match ASCII. Do not use the "/a" (ASCII) modifier, that requires Perl 5.14 and we're only depending on 5.10.1 at the moment.
