[Perfparse-users] No output from perfparse-db-tool

[Tim W. <tim...@pi...>]

All,
I've seen it a couple of times on the mailing list, and now it's happening
to me...

The perfparse-db-tool does not do anything.

I've just compiled perfparse on a new machine (hint: could you please add a
list of necessary libraries to the docs :) ), installed the db schema with
the create script. Next I'm running the db-tool with the --update option. No
output whatsoever. There is nothing in the database (I would have exepected
the db update to enter things in the perfdata_state table).

Did some investigating:
- when db-tool checks the version, it returns the CURRENT version if the
perfdata_state table is empty. So the db-tool thinks all is fine, and does
nothing (a little output in the style 'db is up to date' might come in
handy!)
- when you run perfparse for the first time, it complains about the db
version NOT being correct. Before checking the version, Perfparse writes a
new record to the perfdata_state table, which sets the version field to 0! 
- run the db-tool again. And now it DOES update the database, because the
version is 0, not an empty row.

Problem solved :)

Happy Perf-parsing,
Tim
