I suspect this is coming from MySQLdb. From the Python DB-API spec: OperationalError Exception raised for errors that are related to the database's operation and not necessarily under the control of the programmer, e.g. an unexpected disconnect occurs, the data source name is not found, a transaction could not be processed, a memory allocation error occurred during processing, etc. It must be a subclass of DatabaseError. .frm files seem to be table data containers for MySQL. You should try operating on your database outside of Zope to see if you can reproduce the problem. Curtis Maloney wrote:
Green things,
I've had a site in development (almost ready to deploy) and in testing for some time. I just went to go through another test run, when a previously working page suddenly generated the following error:
Error Type: OperationalError Error Value: (1017, "Can't find file: './service/return.frm' (errno: 13)")
<traceback at end of e-mail>
I looked at the traceback, and it appeared to be coming from a particular SQL method. I tried testing the method, same problem. I tried another SQL method. Same again.
Ok, so I looked into it further, and checked a previous install. I can't find ANY *.frm files in either zope tree.
The only event to day which occurred which might have possibly corrupted files was when i had to reset due to Netscape (eternal be their pain) chewed up all my memory (AGAIN!) and I had to resort to power cycling the computer, since it still hadn't responded to my 'kill this annoyingly stupid app' keystrokes by the time i'd got back from lunch.
However, on bootup, the fsck did not find any problems on the disc, so I felt reasonably safe.
Any ideas? PLEASE?
Installation:
RedHat 6.1 Zope 2.1.6 (from src)
Have a better one, Curtis.
