cmdline adhoc config not picked up

URL remapping is needed to make special remote work. And works with git-annex

git -c 'url.ria+file:///p/largedata/bigbrains/data.insteadof=ria+ssh://judac:/p/largedata/bigbrains/data' annex get datum
get datum (from judac-ria...) 
(checksum...) ok
(recording state in git...)

Same thing with datalad, not workyworky

$ datalad -c 'url.ria+file:///p/largedata/bigbrains/data.insteadof=ria+ssh://judac:/p/largedata/bigbrains/data' get datum
[WARNING] Running get resulted in stderr output: git-annex: get: 1 failed

Confirmed the issue goes away when the config is put into a file.

Thanks for report.

This looks like it boils down to expecting the -c values to be propagated to the underlying git(-annex) calls. While datalad internally uses -c in some of its calls to git, it doesn't pass on the overrides specified via datalad -c.

cd "$(mktemp -d --tmpdir dl-XXXXXXX)"

datalad create a
: >a/f
datalad -C a save

datalad clone a b
datalad -C b --log-level=9 -c foo.bar=baz get f 2>&1 | grep "Running"

[...]
[Level 9] Running: ['git', 'config', '-z', '-l', '--show-origin'] 
[Level 9] Running: ['git', 'annex', 'version', '--raw'] 
[Level 9] Running: ['git', '-c', 'annex.merge-annex-branches=false', 'annex', 'find', '--json', '--json-error-messages', '--not', '--in', '.', '--', 'f'] 
[Level 9] Running: ['git-annex', 'get', '--json', '--json-error-messages', '--json-progress', '-J4', '--', 'f'] 

I haven't thought about it too deeply, but passing along the values wholesale and un-inspected would be problematic because they might conflict with the values that we pass for -c. Pulling out particular overrides of interest seems worth considering, though that sounds like a bottomless pit.

Thanks for the analysis!

FTR: #3456 is concerned with a related topic.

This issue is fixed when installing datalad-next 1.0.0b3 and enabling its datalad-runtime-patching via git config --global --add datalad.extensions.load next.
