NAME

Test::Trap::Builder::TempFile - Capture strategies using File::Temp

VERSION

Version 0.3.4

DESCRIPTION

This module by default provides a capture strategy based on File::Temp for the trap's output layers.

The import accepts a name (as a string; default tempfile) and options (as a hashref; by default empty), and registers a capture strategy with that name and a variant implementation based on the options.

Note that you may specify different strategies for each output layer on the trap.

See also Test::Trap (:stdout and :stderr) and Test::Trap::Builder (output_layer).

OPTIONS

The following options are recognized:

preserve_io_layers

A boolean, indicating whether to apply to the handles writing to and reading from the tempfile, the same perlio layers as are found on the to-be-trapped output handle.

io_layers

A colon-separated string representing perlio layers to be applied to the handles writing to and reading from the tempfile.

If the preserve_io_layers option is set, these perlio layers will be applied on top of the original (preserved) perlio layers.

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 options specify (explicitly or via preserve on handles with) perlio custom layers, they may (or may not) fail to apply to the tempfile read and write handles.

Threads? No idea. It might even work correctly.
