Subject: fetch-pack: prepare updated shallow file before fetching the pack
X-Git-Tag: v1.8.3.2~2^2
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/6035d6aad8ca11954c0d7821f6f3e7c047039c8f?hp=6035d6aad8ca11954c0d7821f6f3e7c047039c8f

fetch-pack: prepare updated shallow file before fetching the pack

index-pack --strict looks up and follows parent commits. If shallow
information is not ready by the time index-pack is run, index-pack may
be led to non-existent objects. Make fetch-pack save shallow file to
disk before invoking index-pack.

git learns new global option --shallow-file to pass on the alternate
shallow file path. Undocumented (and not even support --shallow-file=
syntax) because it's unlikely to be used again elsewhere.
