Mail::SpamAssassin::Util(3)
NAME
Mail::SpamAssassin::Util - utility functions
DESCRIPTION
A general class for utility functions. Please use this for functions
that stand alone, without requiring a $self object, Portability
functions especially.
NOTE: The functions in this module are to be considered private. Their
API may change at any point, and it's expected that they'll only be
used by other Mail::SpamAssassin modules. (TODO: we should probably
revisit this if it's useful for plugin development.)
$module = first_available_module (@module_list)
Return the name of the first module that can be successfully loaded
with "require" from the list. Returns "undef" if none are
available.
This is used instead of "AnyDBM_File" as follows:
my $module = Mail::SpamAssassin::Util::first_available_module
(qw(DB_File GDBM_File NDBM_File SDBM_File));
tie %hash, $module, $path, [... args];
Note that "SDBM_File" is guaranteed to be present, since it comes
with Perl.
my ($filepath, $filehandle) = secure_tmpfile();
Generates a filename for a temporary file, opens it exclusively and
securely, and returns a filehandle to the open file (opened
O_RDWR).
If it cannot open a file after 20 tries, it returns "undef".
my ($dirpath) = secure_tmpdir();
Generates a directory for temporary files. Creates it securely and
returns the path to the directory.
If it cannot create a directory after 20 tries, it returns "undef".
