NAMEMail::SpamAssassin::Util − utility functions
DESCRIPTIONA 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.) NOTE: Utility functions should not be changing global variables such as $_, $1, $2, ... $/, etc. unless explicitly documented. If these variables are in use by these functions, they should be localized. $module = first_available_module (@module_list) Return the name of the first module that can be successfully loaded with \*(C`require\*(C'\fR from the list. Returns \f(CW\*(C`undef\*(C'\fR if none are available. This is used instead of \*(C`AnyDBM_File\*(C'\fR as follows: my $module = Mail::SpamAssassin::Util::first_available_module
(qw(DB_File GDBM_File NDBM_File SDBM_File));
tie %hash, $module, $path, [... args];
Note that \*(C`SDBM_File\*(C'\fR is guaranteed to be present, since it comes with Perl. my ($filepath, $filehandle) = secure_tmpfile(); Generates a filename for a temporary file, opens it exclusively and securely, and returns a filehandle to the open file (opened O_RDWR). If it cannot open a file after 20 tries, it returns \*(C`undef\*(C'\fR. my ($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 \*(C`undef\*(C'\fR. 0
