doc/todo/unified_temporary_file__47__directory_handling.mdwn



Many plugins seem to create temporary files. Although it is not much code, it is duplicated, and a
typical place for security bugs.  Would it be worthwhile to have library functions for creating temporary files
and directories?  If nothing else, it would serve as documentation of the "official way".
Off to cut and paste :-) --[[DavidBremner]]

Hmm, I see only three users of temp files in all ikiwiki:

hnb uses File::Temp::mkstemp to create two temp file handles.
teximg uses File::Temp::tempdir to create a temporary directory.
attachment retrieves a temp file from CGI::tmpFileName.
These are three quite different uses of temp files, not subject to
unification. Using File::Temp (and avoiding the posibly insecure
mktemp, tmpname, and tempnam functions) is probably as unified as
can be managed. --[[Joey]]
