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 doesn't 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 perlfunc and
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 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.
