Summary: High NSWindowController retain counts
Original Submission: When using a subclass of NSWindowController and a Gorm file, the
NSWindowController doesn't get released when the window is closed, because the retain
count is too high. There is a test for this here:
http://www.eskimo.com/~pburns/rob/NSWCTest.tar.gz
It should work on either gnustep or a mac with gnustep-make installed.

The issue was that when "establishConnection" is being called on all of the objects
after the gorm is loaded the code in awakeWithContext was not performing a RELEASE on
the connector. Since the connector is no lonber needed, this should be done.
Once done here are the results of the attached program:
nt after alloc, init, and ordering - 2
2003-08-31 03:27:56.810 NSWCTest[23361] <MyWindowController: 8355d18> retain count
just before RELEASE(self) - 1
2003-08-31 03:28:10.017 NSWCTest[23361] <MyWindowController: 82aa4d0> retain count
upon entering initWithModel: - 1
2003-08-31 03:28:10.017 NSWCTest[23361] <MyWindowController: 82aa4d0> retain count
after initWithWindowNibName:owner: - 1
2003-08-31 03:28:10.019 NSWCTest[23361] Unable to open fixed font
2003-08-31 03:28:10.024 NSWCTest[23361] <MyWindowController: 82aa4d0> retain count
after [self window] - 2
2003-08-31 03:28:10.045 NSWCTest[23361] <MyWindowController: 82aa4d0> retain count
after alloc, init, and ordering - 2
2003-08-31 03:28:16.204 NSWCTest[23361] <MyWindowController: 82aa4d0> retain count
just before RELEASE(self) - 1
Which I believe is correct. I am running some additional tests to make certain this
does not impact anything else, but I believe that this is the solution. GJC

I did look into the problem with the help of our test application and the retain count
seems to come mostly from the NIB loading itself. Here intermediate objects get
generated that never get freed again and thereby retain references to the window
controller, as can be seen from this backtrace:
#0 0x08048fa2 in _i_MyWindowController__retain ()
#1 0x400abd92 in _i_NSNibConnector__setDestination_ ()
from /usr/GNUstep/System/Library/Libraries/libgnustep-gui.so.0
#2 0x401e296d in _i_GSNibContainer__awakeWithContext_ ()
from /usr/GNUstep/System/Library/Libraries/libgnustep-gui.so.0
#3 0x400ac910 in
_c_NSBundle_NSBundleAdditions_loadNibFile_externalNameTable_withZone_ () from
/usr/GNUstep/System/Library/Libraries/libgnustep-gui.so.0
I hope Gregory has an idea to resolve this problem.
