* in recipe with 17 git repos in SRC_URI I've accidentally pasted one SRCREV to
be one character shorter and because fetcher uses:
if not ud.revisions[name] or len(ud.revisions[name]) != 40 or (False in [c in "abcdef0123456789" for c in ud.revisions[name]]):
to decide which SRCREV values are fixed SRCREVs this one was
considered as tag or branch name, because it was only 39 chars long
The original error message wasn't very helpful as it doesn't show
which repo or which SRCREV was considered missing:
do_fetch: Bitbake Fetcher Error: FetchError("Recipe uses a floating tag/branch without a fixed SRCREV yet doesn't call bb.fetch2.get_srcrev() (use SRCPV in PV for OE).", None)
with SRCPV included in PV as error recomments it's a bit better:
bb.data_smart.ExpansionError: Failure expanding variable SRCPV, expression was ${@bb.fetch2.get_srcrev(d)} which triggered exception FetchError: Fetcher failure: Unable to resolve '0a92994d729ff76a58f692d3028ca1b64b145d9' in upstream git repository in git ls-remote output for github.com/Maratyszcza/FP16
The variable dependency chain for the failure is: SRCPV -> PV -> WORKDIR -> T
with this change the first error will read:
do_fetch: Bitbake Fetcher Error: FetchError("Recipe uses a floating tag/branch '0a92994d729ff76a58f692d3028ca1b64b145d9' for repo 'github.com/Maratyszcza/FP16' without a fixed SRCREV yet doesn't call bb.fetch2.get_srcrev() (use SRCPV in PV for OE).", None)

Bitbake
BitBake is a generic task execution engine that allows shell and Python tasks to be run efficiently and in parallel while working within complex inter-task dependency constraints. One of BitBake's main users, OpenEmbedded, takes this core and builds embedded Linux software stacks using a task-oriented approach.
For information about Bitbake, see the OpenEmbedded website: https://www.openembedded.org/
Bitbake plain documentation can be found under the doc directory or its integrated html version at the Yocto Project website: https://docs.yoctoproject.org
Contributing
Please refer to https://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded for guidelines on how to submit patches, just note that the latter documentation is intended for OpenEmbedded (and its core) not bitbake patches (bitbake-devel@lists.openembedded.org) but in general main guidelines apply. Once the commit(s) have been created, the way to send the patch is through git-send-email. For example, to send the last commit (HEAD) on current branch, type:
git send-email -M -1 --to bitbake-devel@lists.openembedded.org

Testing:
Bitbake has a testsuite located in lib/bb/tests/ whichs aim to try and prevent regressions. You can run this with "bitbake-selftest". In particular the fetcher is well covered since it has so many corner cases. The datastore has many tests too. Testing with the testsuite is recommended before submitting patches, particularly to the fetcher and datastore. We also appreciate new test cases and may require them for more obscure issues.
