Subject: lib/bb/fetch2: ignore remote URIs when doing file checksums
X-Git-Tag: rev_ivi_2015_02_04~17037
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=97b227a7a53b8fcb8bfa963debb9482c15d3d908;p=scm%2Fbb%2Ftizen-distro.git

lib/bb/fetch2: ignore remote URIs when doing file checksums

Skip evaluating remote URIs when doing local file checksums, because we
don't need to process them and doing so will trigger a parse failure if
SRCREV is not fully specified. Whilst this is just delaying a check
until runtime (when do_fetch runs for the recipe) we're only validating
this here accidentally and if we did wish to check it during parsing it
ought to be done explicitly.

Fixes [YOCTO #2512]

(Bitbake rev: 99feb77c2de707f2d825566cf48371c48f450e3e)
