Description theknack 2009-03-16 15:48:43 UTC

Build: NetBeans IDE Dev (Build 200903121546)
VM: OpenJDK Client VM, 1.6.0_0-b12, IcedTea6 1.3.1 (6b12-0ubuntu6.1) Runtime Environment, 1.6.0_0-b12
OS: Linux, 2.6.27-11-generic, i386

User Comments:
GUEST: When I'm editing a ruby file, the IDE hangs during a long time (1 minute or so) and then gives an OutOfMemoryError. The error happened when typing a period after self, (ie: self. ). Maybe is related to Code Complete.

I've had this error several times since build 200903081401. Version 200902270313 works fine.

Comment 2 Erno Mononen 2009-03-16 16:23:30 UTC

Thanks for the report, I'll fix this ASAP. This is a performance problem in the new dynamic finded method completer. 
Can you tell me what's maximum amount of columns you have for a table in your app?

Comment 3 theknack 2009-03-17 10:23:53 UTC

I've reproduced the issue. It happens in a Rails model. When I type "self." and I stop typing, a tooltip with "Please
wait..." appears, the IDE hangs for a minute and then raises an OutOfMemory error.

The model has 11 columns in the DB table, but it also has 4 named scopes and it delegates 7 methods to an associated
model. Maybe this will help you.

Thanks for the quick response. NetBeans for Ruby is the best Rails IDE I've used, and I'm using it daily since it's
first version.

If only there would be a better HAML & SASS support... ;-)

Comment 4 Erno Mononen 2009-03-17 11:07:31 UTC

Thanks, that helps. This should be fixed now in #0dce730e5fec, it'll take a while before it gets propagated to the 
daily build though - there should be an automated notification here in this issue once that happens. Thanks again for 
catching this!

PS. Wrt. HAML & SASS - I'll see what I can do for the release after 6.7, for 6.7 I unfortunately don't have the cycles 
to work on that front.
