Merge branch 'ps/send-pack-unhide-error-in-atomic-push' into seen

gitster · gitster · commit c5445680b84f · 2024-11-16T14:56:19.000+09:00
"git push --atomic --porcelain" used to ignore failures from the
other side, losing the error status from the child process, which
has been corrected.

* ps/send-pack-unhide-error-in-atomic-push:
  push: not send push-options to server with --dry-run
  push: only ignore finish_connect() for dry-run mode
  t5543: atomic push reports exit code failure
  t5504: modernize test by moving heredocs into test bodies
  push: fix the behavior of the Done message for porcelain
  t5548: new test cases for push --porcelain and --dry-run
