in thread Notion: CP6AN <strike>should</strike> could be a database

I thought database versioning...

Re-read the context. Modules have version numbers. Sometimes you need to retain access to an older version of a module for one application, whilst moving to using the latest version for new applications. Retaining access to both (or more) versions of the module within the same Perl installation is a problem not currently easily addressable.

The simple expedient of adding a "Version" field to the "Modules" table would allow each application to request any of: the latest version; a specified version; any version before (or after) a given version; etc.

In this context, I chose the word "versioning" to describe that possibility.

Whatever other interpretation you have chosen to read into my use of that word in this context--is wrong.

    Remember this, though: just because a record in the database says there is a version 1.2 doesn't mean it actually exists.

    The database can store a field it calls a "version number", but that doesn't enforce anything on reality.

    I would like to simultaneously store different versions of the same module (I'm looking at you, CGI.pm!), but that's not a issue that a database record will fix. We still have to have some way to store it. Once we have that, we'll be able to figure out which version to get even without a database.

    So, I don't see how the database is doing anything special here, or adding value. I certainly don't think it is doing any "versioning", in any context.

      Sorry? Isn't that just the same as saying "A file that looks like a perl module with version 1.2 may exist in the filesystem, but it could contain COBOL."
