NAME

Test::Trap::Builder::SystemSafe - Output layer backend using File::Temp

VERSION

Version 0.0.5

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 is on an in-memory file, it won't be availible to other processes in any case, so we get an exception instead.

If there is another file handle with the same descriptor (f ex after an open OTHER, '>&=', THIS), we can't get that file descriptor, and we get an exception instead.

Threads? No idea. It might even work correctly.
