Description _ pkuzel 2003-12-22 17:24:01 UTC

Scanning broader context (All Files with mounted
1GB project) takes long time (~1 hour) and can
cause out of memory exception.

The scanning process touches data systems layer
and uses EditorCookie. So any internal performance
problems are multiplied by those in domain modules.

Comment 1 _ pkuzel 2003-12-22 17:27:36 UTC

Both properties and java module needlesly parses their files on
EditorCookie.openDocument() and EditorCookie.close() !!! calls.

SourceTasksView leak

Comment 3 _ pkuzel 2004-02-03 13:31:24 UTC

I plan to add 'direct context' for XML files.

Comment 4 _ pkuzel 2004-02-06 14:34:40 UTC

No more fixes planned in 3.6 timeframe. Generic ENHANCEMENT for next
releases depending on above issues (issue #6050).

Comment 5 _ pkuzel 2004-03-02 17:40:32 UTC

Trond posted enhancement of TODOs scanning code.

We can also narrow providers if only TODOs client view is active.

Comment 6 _ pkuzel 2004-03-03 09:28:43 UTC

Another pending improvement is java.nio usage. It could improve memory
performance a little bit (shared buffer).

Comment 8 _ pkuzel 2004-03-09 13:19:20 UTC

I attached simple patch that should eventually go to release36 too. It
improves TODO scan scalability a little bit. It's must with optional
modules installed.

Comment 9 _ pkuzel 2004-04-06 10:44:32 UTC

ProviderAcceptor.java concept introduced and used in broker code.

Comment 10 Stanislav Aubrecht 2009-09-24 15:25:37 UTC

task list has been completely rewritten
