in reply to Why does Test-WWW-Mechanize-Catalyst-0.55\t\multi_content_type.t hang on win32?

Test-WWW-Mechanize-Catalyst-0.55\t\multi_content_type.t includes

use_ok 'ExternalCatty'; my $pid = ExternalCatty->background($PORT);
ExternalCatty does:
sub background { my $self = shift; my $port = shift; my $child = fork; die "Can't fork Cat HTTP server: $!" unless defined $child; return $child if $child; if ( $^O !~ /MSWin32/ ) { require POSIX; POSIX::setsid() or die "Can't start a new session: $!"; } $self->run($port); }
Maybe the fork is failing?

    Um, no, its hanging, if fork failed, program would end

    $ perl -Mblib t/multi_content_type.t 1..8 # # ################################################################### # Starting an external Catalyst HTTP server on port 7357 # To change the port, please set the TWMC_TEST_PORT env variable. # (The server will be automatically shut-down right after the tests). # ################################################################### ok 1 - use ExternalCatty;

      Without looking further into this - my experience with fork() and sockets on Windows has led me to always spawn external processes (that is, HTTP servers) for module self-testing instead. Launching an external process via pipe-open works for HTTP::Server::Simple, WWW::Mechanize, WWW::Mechanize::Firefox and WWW::Mechanize::Shell.

      I would not bother with investigating why fork and sockets don't interact like on Unix, because the fork-emulation never handled that well anyway.

        Thanks
