.SH "NAME"
Test2::Util \- Tools used by Test2 and friends.
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Collection of tools used by Test2 and friends.
.SH "EXPORTS"
.IX Header "EXPORTS"
All exports are optional. You must specify subs to import.
.ie n .IP "($success, $error) = try { ... }" 4
.el .IP "($success, \f(CW$error\fR) = try { ... }" 4
.IX Item "($success, $error) = try { ... }"
Eval the codeblock, return success or failure, and the error message. This code
protects $@ and $!, they will be restored by the end of the run. This code also
temporarily blocks \f(CW$SIG\fR{\s-1DIE\s0} handlers.
.IP "protect { ... }" 4
.IX Item "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.
.IP "\s-1CAN_FORK\s0" 4
.IX Item "CAN_FORK"
True if this system is capable of true or pseudo-fork.
.IP "\s-1CAN_REALLY_FORK\s0" 4
.IX Item "CAN_REALLY_FORK"
True if the system can really fork. This will be false for systems where fork
is emulated.
.IP "\s-1CAN_THREAD\s0" 4
.IX Item "CAN_THREAD"
True if this system is capable of using threads.
.IP "\s-1USE_THREADS\s0" 4
.IX Item "USE_THREADS"
Returns true if threads are enabled, false if they are not.
.IP "get_tid" 4
.IX Item "get_tid"
This will return the id of the current thread when threads are enabled,
otherwise it returns 0.
.ie n .IP "my $file = pkg_to_file($package)" 4
.el .IP "my \f(CW$file\fR = pkg_to_file($package)" 4
.IX Item "my $file = pkg_to_file($package)"
Convert a package name to a filename.
.SH "NOTES && CAVEATS"
.IX Header "NOTES && CAVEATS"
.IP "5.10.0" 4
.IX Item "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.
.IP "Devel::Cover" 4
.IX Item "Devel::Cover"
Devel::Cover does not support threads. \s-1CAN_THREAD\s0 will return false if
Devel::Cover is loaded before the check is first run.
