code that shows the leak

you need htmltidy and the tidy gem for the example code.

corrected patch

clean out patch(keywords and headers)

[Comment 6 Joshua Kinard 2007-06-23 07:21:28 UTC]

Confirmed on mips.  It's a slow leak.  Started at about 5.8-6MB when launched, and after about 26 mins, it was up to ~8.2MB.

[Comment 7 Hans de Graaff 2007-06-25 19:25:57 UTC]

Just discussed with kingtaco on IRC that it makes sense to apply this patch to ruby 1.8.6_p36 so that we can aim to stabilize that version rather then vanilla 1.8.6.

I'm made a 1.8.6_p36-r3 ebuild locally and have tested.  The memory leak pertaining to loading .so files seems to be resolved.  I'll be deploying to a testing cluster this week and will report back after testing.  IMO we should roll this into -r3 and ship it with stable keywords in mind.(again, this is only my opinion)

[Comment 9 Mike Doty (RETIRED) 2007-06-29 18:09:42 UTC]

I've been testing 1.8.6_p36-r2 with this patch on my beta cluster and memory usage is more stable.  I'd like to roll a -r3 with the patch included.

[Comment 10 Mike Doty (RETIRED) 2007-07-04 06:21:20 UTC]

commited 1.8.6_p36-r3 with the patch.
