Hi all, We make heavy use of SqlAchemy in our app and use a custom 2-phase commit protocol over HTTP to communicate with mobile devices.
While all read,write,deletes happen in a first HTTP request, a subsequent HTTP request needs to find the transaction and either commit or abort. i.e., request 1, start tx read,write,deletes request 2, find tx commit or abort tx There's no requirement per se for sesion objects to be migrated from one thread to another one, but is it safe to save/pickle the SessionTransaction object, until another request in another thread decides that all work done should be committed or aborted ? If the SessionTransaction is unsuitable, is there another way to refer to an existing live transaction from a subsequent request ? We use the zodb transaction, zope.sqlalchemy, tm2 machinery at the moment, so it's possibly to write our own TransactionManager, but the question is really on how do we find and resurrect an existing SA transaction.
