[platform-vcm-dev] Mutlithreading in the Team UI

[Mariano Kamp <mkamp@xxxxxx>]

This is a repost. I posted it the first as the 2.0 version was beeing finalized, probably this was a bad time.

If this is off no interest or whatsoever I would at least appreciate if somebody says so.

Hi,

  I am working on a plugin, where the gui submits long lasting calls (to
a database). Unfortunately the gui locks up then.

  I did see that you guys are facing the same thing when accessing the
repositories. Especially when you connect to a slow cvs server, e.g.
sourcforge, the gui is not responsive anymore.

  There is another similarity. I would divide the issue into two type of
calls. a) Operations on cvs, like check-out or update (in my case
executing queries to a database) and b) calls from a content provider. 

  I think a) is relatively easy to accomplish in my case (no resource
modifications needed) -> just spawn a new thread and implement a call
back, but b) seems to be more complex. The content provider calls don't
provide a progress monitor and now call backs. I do understand the
intention, that these calls should be fast, but as even the resources
can meanwhile live on a ftp or web-dav server this assumptions will not
even last for the simplest case of resources. 


  I know that platform-ui-dev would be the addressee for most of these
things, but I wanted to talk to you first, to see how you want to cope
with it, or doesn't the current behaviour bother you?
  
  I am sure everything could be accomplished with the current API. I've
also read the article from Chris Grindstaff
(http://eclipse.org/articles/treeviewer-cg/TreeViewerArticle.htm) where
he proposes to show some "loading" image and using a callback to deliver
the real information, but he wasn't going into any detail, how to do
that in a non-ugly fashion. I am just wondering if in 3.0 there will
evolve something elegant to solve this common problem?

  On a side bar (just to be on-topic ;-). I really like the 2.0 Team
API. I like the full exposure of the cvs functionality and still the
tight integration into the platform. Great job.

Cheers,
Mariano
