MIME:Parser vs. file permissions

[graff]

I'm using MIME::Parser to extract data attachments from email being sent to me at regular intervals. It's great, and I need only one improvement (for a linux or solaris environment):

The extracted file attachments are being written to disk with owner-only access permissions (rwx------ (700) on directories, and rw------- (600) on data files), and I would prefer at least group-read/execute (750 for directories, 640 for data files) -- global read/execute access would actually be better.

I went over the MIME::Parser and MIME::Parser::Filer man pages, but did not see any relevant information.

What makes it troublesome is that, in the simplest case, you don't really know what paths/files are being created until MIME::Parser is done. You need to figure out afterwards which directories were created, "chmod go+x" on those, then "chmod -R go+r"... (I don't want to make the data files executable.) It would just be a lot easier if the mode flags could be set the way I want in the first place. But how?

The man page for MIME::Parser::Filer says "you can easily define your own subclass of MIME::Parser::Filer and override" the default behavior, but an example (not provided there) would be really helpful... THANKS!

You may wish to try changing your umask. Try perldoc -f umask or man umask. The umask influences the permissions of created files, usually by 'masking' off permission bits which you don't want. Try something along the lines of:

umask(0011);

near the top of your code.

Is this going out live?
No, Homer, very few cartoons are broadcast live - it's a terrible strain on the animator's wrist

Although it's true you may not know what the file names are until MIME::Parser is done, you do have the option of specifying where to store the attachments beforehand:

use strict;
use warnings;
use MIME::Parser;

  my $dir = "./mimemail";
  my $parser = new MIME::Parser;
  $parser->output_dir($dir);
  my $entity = $parser->read(\*STDIN) || die "couldn't parse MIME stre
+am";

You should have enough information at this point to change permissions on the directory or the files within it. Then again, maybe I misunderstand your question. The suggestion by davis should work in any case.
