If I Had a Hammer

[ #34732 ]

After a thread on the dbix-class mailing list about rollback and transactions, I find myself wanting a language wide transaction scope for Perl.

One of the things I like about .NET 2.0 is the transaction scope, wherein anything that is transaction-aware can participate in a transaction scoped block of code, even things that have nothing to do with databases, like file system operations.

If I wanted to update a db (DBI, or DBIC, RDBO, Muldis, an any other) record, update a copy in subversion, plop out a new static html page, and send a confirmation email, it would be keen to wrap that all up in one transaction scope.

My brain melts at the thought of how one would even go about making such a framework in Perl, but it would be a damn fun project.

  • I fully expected to see a reply already, along the lines of "this is how you'll do it in perl 6..."
    • I've seen the P6 page on transactional scalars, ref, etc, but it still reads a little thin on the overall picture. I didn't do a lot of searching though.

      And of course, that's Perl6, which at this point isn't 'real' for me yet.
  • ...has a comment that its on_release can be used to implement transactional mechanics. That comment was there for good reason - I've actually used it that way.

    It is a little bare-bones though. OK, a lot bare-bones.
