bundle2: attribute remote failures to remote (
issue4788)
Before bundle2, hook output from hook failures was prefixed with
"remote: ". Up to this point with bundle2, the output was converted to
the message to print in an Abort exception. This had 2 implications:
1) It was unclear whether an error message came from the local repo
or the remote
2) The exit code changed from 1 to 255
This patch changes the handling of error:abort bundle2 parts during push
to prefix the error message with "remote: ". This restores the old
behavior.
We still preserve the behavior of raising an Abort during bundle2
application failure. This is a regression from pre-bundle2 because the
exit code changed.
Because we no longer raise an Abort with the remote's message, we needed
to insert a message for the new Abort. So, I invented a new error
message for that. This is another change from pre-bundle2. However, I
like the new error message because it states unambiguously who aborted
the push failed, which I think is important for users so they can decide
what's next.
