Re^5: how to timeout an operation under mod

Sorry tye, didn't notice that the name had changed before I replied. Having safe signals that could interrupt DBI would be ideal. This is common enough that maybe DBI actually needs special handling for timeouts built in.

But isn't the problem in the C client libraries that are retrying on EINTR? I don't see a lot that DBI could do about it. -- Online Fortune Cookie Search Office Space merchandise	[reply]

Retrying on EINTR? How annoying! What is the motivation for that? A DBI call seems like the perfect place one would want to interrupt something with a signal (queries can take surprisingly long to run and long-running queries can cause problems for other users of the database so wanting to time-out queries seems an obvious desire). I'd expect such retrying to at least be optional (or to at least not retry on SIGALRM). - tye	[reply]
