When the connectivity check after a fetch fails, an error message "<remote> did not send all necessary objects" is printed. That error message is printed regardless of the reason of failure: in particular, that message may be printed if the connectivity check fails because a local object is missing. (The connectivity check reads local objects too because it compares the set of objects that the remote claims to send against the set of objects that our refs directly or indirectly reference.) Since it is not necessarily true that the remote did not send all necessary objects, update the error message to be something that more correctly reflects the situation. The updated error message is admittedly vague and one alternative solution would be to update the revision walking code to be able to more precisely specify if a bad object is supposed to be available locally or supposed to have been sent by the remote. That would likely require, in the revision walking code, to delay parsing any object until all its children has been parsed, which seems to be a significant undertaking. Signed-off-by: Jonathan Tan <jonathantanmy@xxxxxxxxxx> --- As Junio said in [1], my original v1 code doesn't work when an object is referenced both by a local object and a remote one. I tried looking into making it work but it looks difficult. So here is a patch that just changes the error message to a vaguer but hopefully more correct one. I wonder what the community thinks of it - I think it is more correct (and means that we do not need to say "it's not the remote fault despite what the error message says") but at the same time, many people are already used to this message (and a search online reveals several web sites that talk about this).
