2016-04-29http: avoid corking on "Content-Length: 0" response
We must use a normal write instead of send(.., MSG_MORE) when writing responses of "Content-Length: 0" to avoid the corking effect MSG_MORE provides. We only want to cork headers if we will send a non-empty body. Fixes: c3eeaf664cf0 ("http: clarify intent for persistence") This needs a proper test.
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.
2016-03-06http: reject excessively large HTTP request bodies
We cannot risk using all of a users' disk space buffering gigantic requests. Use the defaults git gives us since we primarily host git repositories.
2016-03-06http: reject excessive headers
HTTP::Parser::XS::PP does not reject excessively large headers like the XS version. Ensure we reject headers over 16K since public-inbox should never need such large request headers.
2016-03-05t/httpd-corner: avoid clobbering existing FDs after fork
Due to the deterministic way reference counting works, we do not want to drop references to existing FDs even if we no longer need the glob reference; the actual FD is all we can pass through on exec.
2016-03-05t/httpd-corner: additional callback test
Just to ensure we hit the code path independently of WWW code.
2016-03-04daemon: support listening on Unix domain sockets
Listening on Unix domain sockets can be convenient for running behind reverse proxies, avoiding port conflicts, limiting access, or avoiding the overhead (if any) of TCP over loopback.
2016-03-03daemon: introduce host_with_port for identifying sockets
This allows us to share more code between daemons and avoids having to make additional syscalls for preparing REMOTE_HOST and REMOTE_PORT in the PSGI env in -httpd. This will also make supporting HTTP (and NNTP) over Unix sockets easier in a future commit.
2016-03-03t/*.t: use identifiable tempdir names
This should make identifiying leftover directories due to SIGKILL-ed tests easier.
2016-02-28http: support graceful shutdown like nntp
HTTP responses may be long-running or requests may be slow or pipelined. Ensure we don't kill them off prematurely.
2016-02-23t/httpd-corner: test HTTP chunking with curl
Just in case my knowledge of chunking is wrong.
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.
