Hi all,
I am trying to embed mozila inside a C application, and in general I
have succeeded to a large degree.
But I have a large problem: memory usage is increased by each page I load.
I have used valgrind to debug the memory usage, but nothing that
originates from code seems to be leaked. All leaked objects seem to have
been created inside mozilla libraries.
Here is the log the debug build of xul runner (compiled from sources)
writes on the terminal:
http://www.ellogon.org/~petasis/sync3/mozilla-debug-log.txt
What puzzles me, are the following issues:
1) I have no history navigation. I can reload the current page, but I
cannot go back/forward. In the log I see warnings like the following:
WARNING: NS_ENSURE_TRUE(compMgr) failed: file nsComponentManagerUtils.cpp, line
90

probably favors chaining over double hashing.

How can I fix this?
2) When the application exits, there is a long list of leaked urls. How
can I free them, so as not to get leaked?
Is there a way to reset everything after I load a single url? To release
the history and cache, and throw everything away?
3) During exit, I get an abort:
ABORT: imgCacheEntry release isn't thread-safe!: '_mOwningThread.GetThread() ==
PR_GetCurrentThread()', file
/home/backup_disk/petasis/TkGecko/mozilla-central/modules/libpr0n/src/imgLoader.h,
line 81
UNKNOWN
[/home/backup_disk/petasis/TkGecko/mozilla-central/obj-xulrunner-d/dist/bin/libxul.so
+0x004C314D]
I think that I have forgot something (what?) that relates to
navigation/cache, and the application keeps everything in memory. Is
this possible?
I would appreciate any help, as I am trying to debug this memory issue
for two weeks now, with little success.
The code can be found here:

George
