We observed that some threads can reach deadlock-ish state after they have Invoked into a control's UI thread. When it happens they are all in a waiting for join or in sleep state for very long time, although there should not be any deadlock situations.
It seems this has something to do with multiple parent controls and with which control we invoked on. This should not make a difference, because we have got one UI thread (for MainWindow) they should wait for, but we have seen it does.
The solution that fixed this issue was to invoke on the MainWindow instead of various controls (see a4fe507adf ).
This changeset is changing all our Invokes to invoke into MainWindow
instead of a control itself. (MainWindow's UI thread is the only UI thread
all Control is using in XenCenter)
This changeset should be in place until we have found the root cause or the exact reason for the above.
Changes to the License Manager dialog:
- Summary panel: show smaller icons for warning and information messages
- Summary panel: show license entitlements for all Creedence hosts (not eligible for support, eligible for support, enterprise features enabled, etc)
- for free Creedence or Clearwater hosts, the license status is Free (it used to be Expired for ClearwaterOrGreater)
and the text displayed is "Unlicensed" for Creedence and "Unsupported" for Clearwater;
the warning message is "Not eligible for support" (instead of "Your support and maintenance has expired")

- Added a 'refresh grid' parameter to UpdateRow() which indicates if a sort and refresh of the grid is necessary.
- A sort and refresh is not needed when the user selects a server by pressing the space key or by mouse, but it is needed when the information displayed has changed, for example when the license has changed.
- Also solved a possible null reference exception in CheckableDataGridViewController.ReplaceStoredRow(), by returning -1 if the index is not within the rows range.

- split the pool members out when they're free, as the activation keys can only be applied to one XenServer host at a time
