Revision 3de4a44308d5c84c468f3fb69a3c3f3092eaf369 authored by Mike Ralphson on 15 July 2009, 14:34:24 UTC, committed by Junio C Hamano on 18 July 2009, 23:57:49 UTC
Reorder tests introduced in fef3a7cc and 54d5cc0e so an intermittent but unimportant failure on the CVS side related to the former does not interfere with what is actually being tested.

/*
* Processing a gitlink entry currently does nothing, since
* we do not recurse into the subproject.
*
* We *could* eventually add a flag that actually does that,
* which would involve:
* - is the subproject actually checked out?
* - if so, see if the subproject has already been added
* to the alternates list, and add it if not.
* - process the commit (or tag) the gitlink points to
* recursively.
*
* However, it's unclear whether there is really ever any
* reason to see superprojects and subprojects as such a
* "unified" object pool (potentially resulting in a totally
* humongous pack - avoiding which was the whole point of
* having gitlinks in the first place!).
*
* So for now, there is just a note that we *could* follow
* the link, and how to do it. Whether it necessarily makes
* any sense what-so-ever to ever do that is another issue.
