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.
