NAME

   starlight - a light and pure-Perl PSGI/Plack HTTP server with pre-forks

SYNOPSIS

     $ starlight --workers=20 --max-reqs-per-child=100 app.psgi

     $ starlight --port=80 --ipv6=1 app.psgi

     $ starlight --port=443 --ssl=1 --ssl-key-file=file.key
                 --ssl-cert-file=file.crt app.psgi

     $ starlight --socket=/tmp/starlight.sock app.psgi

DESCRIPTION

   Starlight is a standalone HTTP/1.1 server with keep-alive support. It
   uses pre-forking. It is pure-Perl implementation which doesn't require
   any XS package.

   Starlight was started as a fork of Thrall server which is a fork of
   Starlet server. It has almost the same code as Thrall and Starlet and
   it was adapted to not use any other modules than Plack.

   Starlight is created for Unix-like systems but it should also work on
   Windows with some limitations.

SEE ALSO

   Starlight, Thrall, Starlet, Starman

LIMITATIONS

   Perl on Windows systems (MSWin32 and cygwin) emulates "fork" in
   perlfunc and "waitpid" in perlfunc functions and uses threads
   internally. See perlfork (MSWin32) and perlcygwin (cygwin) for details
   and limitations.

   It might be better option to use on this system the server with
   explicit threads implementation, i.e. Thrall.

   For Cygwin the perl-libwin32 package is highly recommended, because of
   Win32::Process module which helps to terminate stalled worker
   processes.

BUGS

Windows

   There is a problem with Perl threads implementation which occurs on
   Windows systems (MSWin32). Cygwin version seems to be correct.

   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.

   This problem was introduced in Perl 5.16 and fixed in Perl 5.19.5.

   See https://rt.perl.org/rt3/Public/Bug/Display.html?id=119003 and
   https://github.com/dex4er/Thrall/issues/5 for more information about
   this issue.

   The server fails when worker process calls "exit" in perlfunc function:

     Attempt to free unreferenced scalar: SV 0x293a76c, Perl interpreter:
     0x22dcc0c at lib/Plack/Handler/Starlight.pm line 140.

   It means that Harakiri mode can't work and the server have to be
   started with --max-reqs-per-child=inf option.

   See https://rt.perl.org/Public/Bug/Display.html?id=40565 and
   https://github.com/dex4er/Starlight/issues/1 for more information about
   this issue.
