Description Jiri Rechtacek 2002-11-21 13:33:45 UTC 
(Build 200211211326)
I added to Sources of Sample project a local
directory. The deadlock appears when the expanding
directory. It's easy reproducible.

Comment 3 Vitezslav Stejskal 2002-11-21 14:18:34 UTC 
Although I can say what happens this definitely doesn't look like a
deadlock. Look at your FTDs; both you've posted are different. Is the
IDE really frozen (e.g. no CPU activity)? What sources root have you
mounted in the project? How many packages (approx.) they had?
Comment 4 Jiri Rechtacek 2002-11-21 14:37:44 UTC 
You are right. The computation run for ages and then successfully
finished. I should take more patience.
Comment 5 Vitezslav Stejskal 2002-11-21 15:10:45 UTC 
I wouldn't close this issue. Computing list of packages might be
expensive in case of huge folders tree, but it definitely must not
take ages. There is very likely some performance bug in the
implementation and should find & fix it.
Comment 6 Milan Kubec 2002-11-22 14:17:30 UTC 
I added folder with sources of core module under Sources node and it
took about *35 seconds* to expand that node. It's not related to
Sample Project. Raising priority to P2.
Comment 7 Vitezslav Stejskal 2003-01-02 13:30:00 UTC 
I am not sure whether the new impl of packages node makes this problem
better or worse :-), please check.
Comment 8 Tomas Pavek 2003-05-28 17:47:18 UTC 
I guess we could close this issue as fixed - the performance of
Sources node is not so horrible now it would look like deadlock and
could be considered a defect. I will file a new issue about
performance and scalability problems of exapanding packages under
Packages node.

Issue 33979 filed.

As described in

current work on projects prototype has been stopped.
