| Subject: | 20-no-side-effects.t has side-effect of leaving mysterious snowman in tmp |
I was doing some cleanup in my system /tmp directory and found a weird file called FKq72ErmSX with the content:
Snowman! ☃
I was slightly concerned this might be the calling card of some malicious software, but Googling didn't turn up anything. I then did a systemwide grep for 'Snowman!' (left out the emoji in case it was encoded in the source, as indeed it turned out to be), and found it in .cpan/build/File-Slurper-0.010-0/t/20-no-side-effects.t. Kind of ironic that a file with that name has a side effect like that.
I see you're calling tempfile() as:
my ( $outfh, $outputfile ) = tempfile();
and not doing anything to explicitly delete the file at the end of the test. Please either manually delete it, or call tempfile() in such a way that it's auto-deleted. From the File::Temp docs:
($fh, $filename) = tempfile($template, UNLINK => 1);
Return the filename and filehandle as before except that the
file is automatically removed when the program exits
(dependent on $KEEP_ALL). Default is for the file to be
removed if a file handle is requested and to be kept if the
filename is requested. In a scalar context (where no filename
is returned) the file is always deleted either (depending on
the operating system) on exit or when it is closed (unless
$KEEP_ALL is true when the temp file is created).
Use the object-oriented interface if fine-grained control of
when a file is removed is required.
I haven't tried building File-Slurper-0.012, but I confirmed that 20-no-side-effects.t is unchanged in it.
Thanks much, [Odd to manually sign a bug report, but having acct.
