NAME

Test::Stream::Capabilities - Check if the current system has various capabilities.

EXPERIMENTAL CODE WARNING

This is an experimental release! Test-Stream, and all its components are still in an experimental phase. This dist has been released to cpan in order to allow testers and early adopters the chance to write experimental new tools with it, or to add experimental support for it into old tools.

PLEASE DO NOT COMPLETELY CONVERT OLD TOOLS YET. This experimental release is very likely to see a lot of code churn. API's may break at any time. Test-Stream should NOT be depended on by any toolchain level tools until the experimental phase is over.

SYNOPSIS

    use Test::Stream::Capabilities qw/CAN_FORK CAN_REALLY_FORK CAN_THREAD/;

    if (CAN_FORK) {
        my $pid = fork();
        ...
    }

    if (CAN_REALLY_FORK) {
        my $pid = fork();
        ...
    }

    if (CAN_THREAD) {
        threads->new(sub { ... });
    }

DESCRIPTION

This module will export requested constants which will always be a boolean true or false.

AVAILABLE CHECKS

CAN_FORK

True if this system is capable of true or psuedo-fork.

CAN_REALLY_FORK

True if the system can really fork. This will be false for systems where fork is emulated.

CAN_THREAD

True if this system is capable of using threads.

NOTES && CAVEATS

5.10.0

Perl 5.10.0 has a bug when compiled with newer gcc versions. This bug causes a segfault whenever a new thread is launched. Test::Stream will attempt to detect this, and note that the system is not capable of forking when it is detected.

Devel::Cover

Devel::Cover does not support threads. CHECK_THREADS will return false if Devel::Cover is loaded before the check is first run.
