reports don't work with PostgreSQL

Reported by: arthur_kalm Owned by: Russ Tyndall
Priority: normal Component: TimingAndEstimationPlugin
Severity: major Keywords: postgresql
Cc: akalmenson@… Trac Release: 0.10


Hi, we're using the plugin with PostgreSQL. When using it in simple projects, the reports from the management tab work well. However, when we try to use the plugin from a relatively large project, and try to view any reports from the management tab (for example, the "Ticket Hours" report), we get the following error:

Traceback (most recent call last):

I am not running python 2.5, so it might be a problem with that. It kind of sounds like perhaps the command is timing out or something?

I will try to look into this further a bit later in the week.

Thanks, Russ

Well for simple projects that have only a few tickets, it works fine, even with python 2.5. We could try our trac instance out with python 2.4, but it's kind of confusing why it works for small projects (a few tickets) and not for larger ones (dozens of tickets).

Regards, Arthur

Honestly, my best bet is still that on larger datasets, it is exceeding the default timeout length which would cause the tranny to abort.

I am also not familiar whit pyPgSQL/, but it might be easy to change its default timeout (which could solve this problem). Alternatively, you might try adding a TOP/LIMIT 10 or other such limiting statement to the query to try to reduce the result set which might allow you to better determine if this is a timeout issue.

Sorry I cant be of more assistance at the moment. I am a bit tied up with other projects at the moment. I also do not have an instance of trac running against postegres using that driver, so it would be a fairish amount of work to get your scenario running on my end to recreate the issue.

You might want to try updating to the new version I changed the reports a bit based off of someone else's problems with postegres and the reports.
