Description Petr Jiricka 2009-09-14 16:22:14 UTC

1. Follow steps 1-4 in http://www.netbeans.org/issues/show_bug.cgi?id=134990#desc51 to generate a project with a few
hundred Java files
2. Select all Java files per scenario A)
3. Delete all these files per scenario B)

You will see that the IDE starts deleting and files start disappearing in the explorer, but scanning is started
simultaneously, which slows things down terribly. I think the scanning should be started only after all the files are
deleted - that would hopefully make things faster.

We have kind of similar issue 167098 for version control operations, i.e. process all events at once in the end. Might
be related, but this one could also have a different solution.

Comment 2 Vitezslav Stejskal 2009-09-16 16:56:51 UTC

If the Delete action deleted the files in one FileSystem.AtomicAction the events would be processed as a whole bunch.
I'm not sure how the action is implemented, but perhaps it deletes each file separately.
