NAME

       Test2::Util - Tools used by Test2 and friends.

DESCRIPTION

       Collection of tools used by Test2 and friends.

EXPORTS

       All exports are optional. You must specify subs to import.

       ($success, $error) = try { ... }
           Eval  the  codeblock, return success or failure, and the error message. This code protects $@ and $!,
           they will be restored by the end of the run. This code also temporarily blocks $SIG{DIE} handlers.

       protect { ... }
           Similar to try, except that it does not catch exceptions. The idea here is to protect $@ and $!  from
           changes. $@ and $! will be restored to whatever they were before the run so long as it is successful.
           If the run fails $! will still be restored, but $@ will contain the exception being thrown.

       CAN_FORK
           True if this system is capable of true or pseudo-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.

       USE_THREADS
           Returns true if threads are enabled, false if they are not.

       get_tid
           This will return the id of the current thread when threads are enabled, otherwise it returns 0.

       my $file = pkg_to_file($package)
           Convert a package name to a filename.

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. Test2 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. CAN_THREAD will return false if Devel::Cover is loaded  before
           the check is first run.
