[oe] buildindex is always 0, using BB_GIT_CLONE_FOR_SRCREV = "1"

[Radoslav Kolev]

Hi,

I'm trying to make a recipe which gets the newest revision from a git
repository.

Also to get upgradable packages on different build machines I have the

BB_GIT_CLONE_FOR_SRCREV = "1"

option set in my local.conf.

In the recipe I have

SRCREV = "${AUTOREV}"
PV = "0.4+gitr-${SRCPV}"

but I always get a PV of the form
0.4+gitr-0+f5bb7404c351a08cf405fbe8d667b446ae8e0ef5-r10 where the
buildindex stays at zero, even though new revisions are correctly
checked out from the git repository.

I added some print statements to bitbake/lib/bb/fetch/__init__.py and
git.py and it seems to work fine until some point.

The _sortable_buildindex in git.py returns the correct incrementing
value, also the first invocation of get_srcrev() returns a correct
value with incrementing buildindex like
168+f5bb7404c351a08cf405fbe8d667b446ae8e0ef5l. But then something
happens and in all subsequent invocations by bitbakeit get_srcrev()
always returns 0+f5bb7404c351a08cf405fbe8d667b446ae8e0ef5l.

Any help or ideas how to further debug the issue are greatly
appreciated.  I'm using bitbake 1.10.

Best regards,
