Re: r27812 - in /libs/gui/trunk: ChangeLog Source/NSBundleAdditions.m

[Doug Simons]

Unfortunately, this change (Fred's commit in r29223) has broken our ported Cocoa application (at least on Windows -- haven't had time to check on Linux yet). At least some objects in our nib files are now freed after the nib loads, and our application crashes when trying to access them. Reverting NSBundleAdditions.m to the version prior to r29223 fixes the problem for us. 

We would appreciate if this change could be backed out until this problem can be resolved. I don't understand everything that's going on during nib loading well enough to  attempt to solve this myself. Thanks!

Thank you for looking into this.

Looks like the basic difference between Cocoa and us is in the window,

window controller and document interaction. And you are the sole expert

we have on this :-)

At the end of the day it looks like my expertise isn't needed here. The

problem rather seems to be a space leak in the nib loading code, which

seems to retain the owner of the nib file. To make testing a bit simpler

I've attached a hopefully faithful translation of Ink's Document.gorm

into a nib file with Apple's InterfaceBuilder. When I use that nib file

instead of Document.gorm, Ink does not release the document when its

window is closed. The window itself and its window controller are

released correctly.

Thank you for looking into this: I will try to resolve this issue. I
remember scattering FIXME's in the NIB loading code some time ago. One
of them might come in helpful now.

I think it is now save to replace the NIB outlet connector code. I just

checked the old code against the new runtime functions of base and as

far as I can tell the old code would still work. We could just revert my

change.

Please do so.

Done :-)
