Current fetcher has annoying "SRCREVINACTION" deadlock,
which occurs when SRCREV=${AUTOREV}=@bb.fetch.get_srcrev():
get_srcrev()->setup_localpath()->srcrev_internal_helper()
->evaluate SRCREV->get_srcrev()
Current fetcher resolve the deadlock by introducing a
"SRCREVINACTION" condition check. Althoguh it works, it is
indeed not clean.
This patch use Richard's idea to break the deadlock: break
the dependency among SRCREV and get_srcrev(), i.e. assign
a specific keyword "AUTOINC" to AUTOREV. when Fetcher meet
this keyword, it will check and set the latest revision to
urldata.revision. get_srcrev later can use the urldata.revision
for value evaluation(SRCPV etc). In this case, SRCREV no longer
depends on get_srcrev, and there is not deadlock anymore.
In implementation side, several things are done:
a) set the revision in FetchData:__init__, so that
urldata.revision is ready when get_srcrev() need it
b) init fetch method specific data in Fetch:supports, so that
Fetch.latest_revision() can be conducted when FetchData:
__init__ need it to achieve a)
c) some recpies still use ${SRCREV} in PV, which is not corect
logically, and will cause error in current implementation.
so replace the SRCREV with SRCPV for those recpies
in test side, some basic tests are conducted:
- fetch the source of world packages from scratch (empty DL_DIR)
- bitbake poky-image-sato for qemux86 from sratch (empty DL_DIR)
more testing is ongoing, this RFC is just for early patch review
and comments are warmly welcome.
