[interfacekit] Re: Broken BMessage

Following Ingo's very clear instructions, I was able to confirm that any BMessage-related issues with BAppFileInfo appear to be fixed. There are still unit test failures, but these have to do with MIME type installation failing. The problem appears to be in Database::Install() (in /src/kits/storage/mime/Database.cpp); if /boot/home/config/settings/obos_mime/application (I think that's what it's called) doesn't exist, the function simply errs out, rather than creating the directory, which seems to me the appropriate thing to do. Obviously, Storage Kit is not my baliwick, so I haven't attempted to make a fix/*really* messed things up. ;)

I'll be trying to find time to diagnose and fix the remaining issues next week.

Thanks,

I finally found the time to do some work. Fixed the SendMessageTest1() issue (BMessage::fWasDelivered wasn't getting initialized when unflattening); that now passes. Unfortunately, the OBOS version of the unit tests for storage kit don't seem to get loaded, though everything looks correct: the lib is in the right place and is exporting the right entry point. If anybody has any idea why that might be, I'd love some suggestions; otherwise I'll have to do a debug build of the testing framework and step through. =P

Couldn't get anywhere with the BApplication tests, on account of app_server dying on a strcmp() in CursorManager::RemoveAppCursors() during QuitTest2(). Anyway, still pokin' away here when time presents itself. =)

The BNodeInfo test still crashes the registrar:

main_mime:

The BAppFileInfo unit test doesn't crash anymore in the "Supported

Types

Test", but the test case fails and the following test case ("Icon

Test")

hangs. It seems like the "main_mime" thread (a BLooper thread) gets terminated somehow and the test app is waiting for a reply on a

temporary 

message port for good. The same holds for the BMimeType unit test.

The BApplication unit test (the remote application, to be precise) 

crashs:
