Not if the app doesn't. From a brief test, TG apps do not do this.
MirrorManager doesn't use transactions, I never figured out how to get
them to work right. Advice welcome.
By not being able to get transactions working, do you mean explicit
transactions or implicit transactions? I see that mirrormanager, bodhi,
and noc (not running currently) are using a dburi that disables
implicit transactions::
mirrormanager-prod.cfg.erb:
sqlobject.dburi="notrans_postgres://mirroradmin:
<%= mirrorPassword %>@db2.fedora.phx.redhat.com/mirrormanager"
If that was changed to::
sqlobject.dburi="postgres://mirroradmin:[...]
TurboGears would at least attempt to use an implicit transaction per
http request which should protect the database from shutting down the
application in the middle of processing a multi-table update. I don't
know if that's the problem you're referring to, though.
