(how I really really wish i didn't have to use 2.4 anymore ;) But lets at least be clear that is never acceptable for a python implementation to leak file descriptors/handles (or other system resources), they should be closed and released whenever the particular GC implementation gets around to it. > > You make a very good point!

If so I'll happily go update those docs with a caveat. I regularly point out in code reviews that the very convenient and common idiom of open(name, 'w').write(data) doesn't guarantee when the file will be closed; its up to the GC implementation details. Good code should never depend on the GC for a timely release of scarce external resources (file descriptors/handles). -------------- next part -------------- An HTML attachment was scrubbed...
