[cdt-dev] RE: Problem with large source files in CDT 6.0.1
|
I've gathered some details on a slightly different aspect
of this problem.
A - Opening a 8500 line C++ file
B - The outline appears
C - Highlighting of types/variables
appears
I'm running this on a slowish Solaris system, which I'm
sure exacerbates the problem. In CDT 5.0.2, the
time between A & B is about 5 seconds and the time between B & C is 1 or
2 seconds. In CDT 6.0.1, the AB interval is again about 5
seconds, but the BC interval is 20 seconds. For a huge 38,000
line file, BC is around 3 minutes.
I've turned on all the CDT tracing options that I know of
and for the majority of the BC interval there's no corresponding tracing output
although there's obviously something going on (CPU usage/100s of mb of
allocation/deallocation).
I tried to file a bug report yesterday but it was eaten by
a bugzilla internal error (didn't like my choosing OS & HW
=other).

We have some rather large source files (e.g, around 39,000 lines).
CDT 5.0.2 handled them pretty well--after opening the file it took about 30
seconds for the outline to show up and all the syntax highlighting to
appear. I just set up a CDT 6.0.1 install and have found the large file
handling is not working as well. After opening a large file, the outline
shows up in 30s, but it takes an additional 3-4 minutes for the highlighting
on variables/types to show up. During this time, hovers don't usually
work (but oddly sometimes do). Even worse, every F3 (open declaration)
operation takes 3-4 minutes to complete. I'm watching the heap mem usage
in jconsole and it uses and releases 200mb of memory 6 times before the
operation completes.
Any ideas what's going on here?
Thanks,
Steve Kennedy
