Description Boudewijn Rempt 2004-02-05 16:16:07 UTC

Version:           1.2 (using KDE 3.2.0, SuSE)
Compiler:          gcc version 3.3 20030226 (prerelease) (SuSE Linux)
OS:          Linux (i686) release 2.4.20-4GB-athlon

Im trying to recreate Krita's class diagram -- I lost the previous one-- and am thus trying to import everything in krita/core and subdirs into Umbrello. This quickly brings my computer to its knees, because it appears to be taking really enormous amounts of memory. After a twenty or so imports, Umbrello appears to take about 500mb; when shutting down, starting up again and loading the file, that's down to 50 MB or so.

I think I can complete the task, but only by importing a few classes, shutting down, starting up, importing the next five, lather, shave, rinse, repeat... And when loading the file I get lots of warnings like this:

umbrello: WARNING:  LOAD FROM XMI: MISSING CODE DOCUMENT, plowing ahead with pre-generated one.
umbrello: WARNING:  * findCodeDocumentByID finds NO match to [cppheader2363]

umbrello: ERROR:  DANGER DANGER! DIDNT find code classfield for id:2213 corrupt code generator?
umbrello: ERROR: ERROR: cant find code classfield for ID:2213 do you have a corrupt savefile?

umbrello: ERROR: ERROR! corrupt save file? cant get proper UMLRole for codeparameter:2191 w/role_id:0

And that makes me a little uneasy.

This is due to the code generation and undo/redo.

Delete everything in <codegenerators> in the saved file, start umbrello and change to a code generator which doesn't create code (such as Perl) before opening the diagram or importing the classes.

Hardly ideal I know.

Eek! But could I switch to a C++ code generator one I have my new classes 
added to the diagram, generate, and switch it off again?

You would need to delete the <codegenerators> tag in the saved file again to keep memory down.
