[PyCS-devel] forking inside a module script

[Phillip P. <pp...@my...>]

Hi,

I've decided that the safest way to run htsearch is to fork inside the
module script, run htsearch in the child process, and let the OS clean
up after it.

(how to do this in Python, for ppl who're interested:

However, I found that the module handler catches SystemExit
exceptions, meaning that the child processes weren't being allowed to
exit properly.  I've changed pycs_module_handler to just re-raise if
it gets a SystemExit, but it looks like Medusa also catches it.
Here's a quick diff to get Medusa to re-raise too:

                         (file, fun, line), t, v, tbinfo = asyncore.compact_traceback()

I guess we should push this one over to the Medusa people too ...

(I haven't put any of the search stuff into CVS yet BTW, but will
soonish hopefully).

Cheers,
