p2 hangs because slow server that has no conection to the downloaded plugin

Build ID: I20080617-2000

Steps To Reproduce:
1. Start Eclipse
2. Try to install a new plugin from http://update.codecover.org or some other update server
3. p2 will hang (at the moment at least, while there is a problem with the eclipse update server)


More information:
Hi all,

We've have just a very bad experience tring to install a new plugin inside eclipse ganymed using p2. We can't install any plugin any more in none of our Ganymed installations at the moment as p2 simply hangs.

The reason seems to be a very slow update server (http://download.eclipse.org/tools/mylyn/e3.4/features/ ???). May it be that p2 tries to connect to this server and does not timeout? If this is the case it would very critical ... if one server is slow no one could install a plugin any more.

I've tried to install different plugins on different computers the last 2 hours and updating is simply not possible any more (tries e.g. http://update.codecover.org ).

Could you please try to install the content from the zip available on http://wiki.eclipse.org/ECF_Apache_Httpclient-Based_Provider and see if this helps with the problem?
Also does that happen consistently?

> Also does that happen consistently?

It has happened only today and only for a few hours (~4h).

Now, after waiting a few hours, all works again. I can update all plugins from all update sites on all our computers. I would assume the  server problem is fixed in the meantime.

Anyway I fear, if there is a server problem in the future the update problematic may be reappear. Does p2 try to connect to other servers as the one I select for my update? If so, maybe this can be changed?

As the problem does not appear any more I can't test http://wiki.eclipse.org/ECF_Apache_Httpclient-Based_Provider .
