test::trap::builder::systemsafe
Test::Trap::Builder::SystemSafe(3) User Contributed Perl Documentation Test::Trap::Builder::SystemSafe(3)NAME
Test::Trap::Builder::SystemSafe - "Safe" output layer backend using File::Temp
VERSION
Version 0.2.3
DESCRIPTION
This module provides an implementation systemsafe, based on File::Temp, for the trap's output layers. This implementation insists on
reopening the output file handles with the same descriptors, and therefore, unlike Test::Trap::Builder::TempFile and
Test::Trap::Builder::PerlIO, is able to trap output from forked-off processes, including system().
See also Test::Trap (:stdout and :stderr) and Test::Trap::Builder (output_layer).
CAVEATS
Using File::Temp, we need privileges to create tempfiles.
We need disk space for the output of every trap (it should clean up after the trap is sprung).
Disk access may be slow -- certainly compared to the in-memory files of PerlIO.
If the file handle we try to trap using this backend is on an in-memory file, it would not be available to other processes in any case.
Rather than change the semantics of the trapped code or silently fail to trap output from forked-off processes, we just raise an exception
in this case.
If there is another file handle with the same descriptor (f ex after an "open OTHER, '>&=', THIS"), we can't get that file descriptor.
Rather than silently fail, we again raise an exception.
Threads? No idea. It might even work correctly.
