Re: Questions about full GC at allocation failure

[DAISUKE NAKAJIMA <dn97834@...>]

Thank you for information, Bogdan and Luiz.

We will try http://lua-users.org/wiki/EmergencyGarbageCollector for 5.1.4 first.

Thanks,
Daisuke

Thank you for quick reply, Steve.

So can I expect this issue is resolved to some extent by this new feature?
This is a good news!

Probably a good way to confirm with this would be to try Lua 5.2 beta.

Or you can try this instead:

http://lua-users.org/wiki/EmergencyGarbageCollector

It brins emergency garbage collection capabilities to Lua 5.1 with a patch.  I tested it and it definitely helps in low memory conditions.

Best,

Bogdan

It's definitely a feature in Lua 5.2, but not in Lua 5.1 (perhaps as
the FAQ maintainer I should make this more clear)
