NAME
thrall - a simple PSGI/Plack HTTP server which uses threads
SYNOPSIS
$ thrall --workers=20 --max-reqs-per-child=100 app.psgi
$ thrall --port=80 --ipv6=1 app.psgi
$ thrall --port=443 --ssl=1 --ssl-key-file=file.key --ssl-cert-file=file.crt app.psgi
$ thrall --socket=/tmp/thrall.sock app.psgi
DESCRIPTION
Thrall is a standalone HTTP/1.1 server with keep-alive support. It uses
threads instead pre-forking, so it works correctly on Windows. It is
pure-Perl implementation which doesn't require any XS package.
Thrall was started as a fork of Starlet server. It has almost the same
code as Starlet and it was adapted to use threads instead fork().
SEE ALSO
Starlight, Starlet, Starman
LIMITATIONS
See "BUGS AND LIMITATIONS" in threads and "Thread-Safety of System
Libraries" in perlthrtut to read about limitations for PSGI
applications started with Thrall and check if you encountered a known
problem.
Especially, PSGI applications should avoid: changing current working
directory, catching signals, starting new processes. Environment
variables might (Linux, Unix) or might not (Windows) be shared between
threads.
Thrall is very slow on first request for each thread. It is because
spawning new thread is slow in Perl itself. Thrall is very fast on
another requests and generally is faster than any implementation which
uses fork.
BUGS
There is a problem with Perl threads implementation which occurs on
Windows. Some requests can fail with message:
failed to set socket to nonblocking mode:An operation was attempted on
something that is not a socket.
or
Bad file descriptor at (eval 24) line 4.
Cygwin version seems to be correct.
This problem was introduced in Perl 5.16 and fixed in Perl 5.19.5.
