crashing server during a mysql test

[Zardosht Kasheff]

Hello all,

Is there a way to kill a server in the MySQL test framework? I
understand that --shutdown_server num_seconds will shut the server
down, and if the server has not gone down after num_seconds, the
process will be killed, but I am looking for something that guarantees
a kill.

Thanks

For deterministic kill it can be done via the test/debug macros. We do
this frequently in tests added to the Facebook patch. Official MySQL
has very few crash recovery tests. Here is an example:

Grep server source for "crash_commit_before" to see how this is done
