We're trying to make sense of some external code that was given to us. The code is a Mason web front-end to some mysql INNODB tables. Access to the tables is through Class::DBI (hence Ima). The code is running from mod_perl 1.99 on Apache 2. The code uses transactions.

Here's the semi-mystery: within one browser window, the app changes the DB, and those changes are seen. From a different browser window, however, those changes are sometimes not seen -- the other window (be it on a different client box, or a different browser on the same client box), it is as if the database doesn't see the txn, or the commit.

Anyone have any clues as to what this might be, as we explore the code and start ex-post-facto building tests for it? There do appear to be  Table->dbi_commit in the right places, but, we're just diving into this morass....

In reply to advice about 'stale' data --> Ima, shared dbh handles, and txns by water
