2021-07-20httpd: fix SIGHUP by invalidating cache on reload
Since we require separate PublicInbox::HTTPD instances for each listen socket address (in order to support {SERVER_<NAME|PORT>} for PSGI env), the old cache needed to be invalidated on rare app refreshes. SIGHUP has always been broken in -httpd (but not -imapd or -nntpd) due to this cache. Update the daemon documentation and 5.10.1-ize some bits while we're in the area.
2021-03-15t/httpd: convert to create_inbox
No real difference, here, but having less code is nice.
2021-02-08tests: favor IPv6
IPv4 gets plenty of real-world coverage, and apparently there's Debian buildd hosts which lack IPv4(*). So ensure everything can work on IPv6 and not cause problems for odd setups. (*) https://bugs.debian.org/979432
2021-01-01update copyrights for 2021
Using "make update-copyrights" after setting GNULIB_PATH in my config.mak
2020-05-09remove most internal Email::MIME usage
We no longer load or use Email::MIME outside of comparison tests.
2020-04-22t/*.t: reduce dependency on Email::MIME APIs
Instead, favor PublicInbox::MIME->new for non-attachment emails. We may support alternatives to Email::MIME down the line. We'll still keep Email::MIME->create to deal with attachments, for now, but there's also a fair amount of test duplication we should eliminate, later.
2020-04-20testcommon: spawn-aware system() and qx[] workalikes
Barely noticeable on Linux, but this gives a 1-2% speedup on a FreeBSD 11.3 VM and lets us use built-in redirects rather than relying on /bin/sh.
2020-02-06treewide: run update-copyrights from gnulib for 2019
I didn't wait until September to do it, this year!
2020-02-04www: stricter regexp for 405 errors
We want to match "GET" and "HEAD" exactly, not requests which start with "GET" or end with "HEAD". This doesn't seem like a real problem for public-inboxes which are actually public data anyways.
2020-01-28daemon: provide TCP_DEFER_ACCEPT for Perl <5.14
Socket::TCP_DEFER_ACCEPT() did not appear in the Socket module distributed with Perl until 5.14, despite it being available since Linux 2.4.
2019-12-24testcommon: add require_mods method and use it
This cuts down on lines of code in individual test cases and fixes some misnamed error messages by using "$0" consistently. This will also provide us with a method of swapping out dependencies which provide equivalent functionality (e.g "Xapian" SWIG can replace "Search::Xapian" XS bindings).
2019-12-19tests: move t/common.perl to PublicInbox::TestCommon
We want to be able to use run_script with *.t files, so t/common.perl putting subs into the top-level "main" namespace won't work. Instead, make it a module which uses Exporter like other libraries.
2019-11-24tests: use File::Temp->newdir instead of tempdir()
We'll also introduce a tmpdir() API to give tempdirs consistent names.
2019-11-24t/common: start_script replaces spawn_listener
We can shave several hundred milliseconds off tests which spawn daemons by preloading and avoiding startup time for common modules which are already loaded in the parent process. This also gives ENV{TAIL} support to all tests which support daemons which log to stdout/stderr.
2019-11-16t/httpd: use run_script for -init
This only gives a small ~10% speedup, since -httpd still needs execve, but any speedup is welcome.
2019-11-08t/*.t: disable nntpd/httpd worker processes in most tests
And explicitly test for respawning in t/httpd-corner.t There's no need to have an extra entries in the process table for most tests we run, since that's not what we're testing.
2019-09-09run update-copyrights from gnulib for 2019
2019-09-09tests: add tcp_connect() helper
IO::Socket::INET->new is rather verbose with the options hash, extract it into a standalone sub
2019-06-30tests: common tcp_server and unix_server helpers
IO::Socket:*->new options are verbose and we can save a bunch of code by putting this into t/common.perl, since the related spawn_listener stuff is already there.
2019-06-24daemon: use FreeBSD accept filters on non-NNTP
Similar to TCP_DEFER_ACCEPT on Linux, FreeBSD has a 'dataready' accept filter which we can use to reduce wakeups when doing TLS negotiation or plain HTTP. There's also a 'httpready' which we can use for plain HTTP connections.
2019-06-24daemon: set TCP_DEFER_ACCEPT on everything but NNTP
This Linux-specific option can save us some wakeups during the TLS negotiation phase, and it can help with ordinary HTTP, too. Plain NNTP (and in the future, POP3) are the only things which require the server send messages, first.
2019-05-14tests: get rid of unnecessary Cwd module use
We only need it for tests that chdir, and maybe for ENV{PATH} portability (dash seems fine, not sure about others). v2: revert change to solver_git.t for FreeBSD 11.2 and document
2019-05-14tests: remove unnecessary loading of ::DS and Socket
PublicInbox::DS works for every platform we we care about, nowadays; so checking for it is a waste of time. Cleanup a few POSIX and Socket imports while we're in the area.
2019-05-04bundle Danga::Socket and Sys::Syscall
These modules are unmaintained upstream at the moment, but I'll be able to help with the intended maintainer once/if CPAN ownership is transferred. OTOH, we've been waiting for that transfer for several years, now... Changes I intend to make: * EPOLLEXCLUSIVE for Linux * remove unused fields wasting memory * kqueue bugfixes e.g. https://rt.cpan.org/Ticket/Display.html?id=116615 * accept4 support And some lower priority experiments: * switch to EV_ONESHOT / EPOLLONESHOT (incompatible changes) * nginx-style buffering to tmpfile instead of string array * sendfile off tmpfile buffers * io_uring maybe?
2018-12-29tests: consolidate process spawning code.
IPC::Run provides a nice simplification in several places; and we already use it (optionally) on a lot of tests. For the non-test code, we still rely on our vfork-capable Inline::C stuff since real-world server processes can get large enough to where vfork is an advantage. Maybe Perl5 can use CLONE_VFORK somehow, one day: https://rt.perl.org/Ticket/Display.html?id=128227 Ohg V'q engure cbeg choyvp-vaobk gb Ehol :C
2018-02-07update copyrights for 2018
Using update-copyrights from gnulib While we're at it, use the SPDX identifier for AGPL-3.0+ to ease mechanical processing.
2017-06-26mda: set List-ID correctly according to RFC2919
Oops, due to an old mistake , List-ID was set incorrectly in the MDA. This could cause some breakage w.r.t. mail filters.
2016-07-02www: remove Plack::Request dependency entirely
Lighter and ever-so-slightly faster! Most importantly, this won't do non-obvious stuff behind our backs like trying to parse a POST request body for a query string param.
2016-05-02t/*.t: reduce -mda calls
Process startup times are atrocious for fast tests and there's far too much setup involved. Rely on git-fast-import instead; but more work is needed in this area.
2016-04-28githttpbackend: clamp to one smart HTTP request at-a-time
Server admins may not be able to afford to have too many git-pack-objects processes running at once. Since PSGI HTTP servers should already be configured to use multiple processes for other requests; limit concurrency of smart backends to one; and fall back to dumb responses if we're already generating a pack.
2016-04-28githttpbackend: fall back to dumb if smart HTTP is off
Using http.getanyfile still keeps the http-backend process alive, so it's better to break out of that process and handle serving entirely within the HTTP server.
2016-03-12http: use Plack::HTTPParser for HTTP parsing
This allows us to reduce installation dependencies while retaining performance as it favors HTTP::Parser::XS when it is installed and available. PLACK_HTTP_PARSER_PP may be set to 1 to force a pure Perl parser for testing.
2016-03-03t/*.t: use identifiable tempdir names
This should make identifiying leftover directories due to SIGKILL-ed tests easier.
2016-02-23initial public-inbox-httpd implemenation
This is meant to provide an easy starting point for server admins. It provides a basic HTTP server for admins unfamiliar with configuring PSGI applications as well as being an identical interface for management as our nntpd implementation. This HTTP server may also be a generic Plack/PSGI server for existing Plack/PSGI applications.
