This tests notmuch new's ability to recover from arbitrary stopping failures. It interrupts notmuch new after every database commit and, on every resulting database snapshot, re-runs notmuch new to completion and checks that the final database state is invariant.

# This gdb script runs notmuch new and simulates killing and
|
|
# restarting notmuch new after every Xapian commit. To simulate this
|
|
# more efficiently, this script runs notmuch new and, immediately
|
|
# after every Xapian commit, it *pauses* the running notmuch new,
|
|
# copies the entire database and maildir to a snapshot directory, and
|
|
# executes a full notmuch new on that snapshot, comparing the final
|
|
# results with the expected output. It can then resume the paused
|
|
# notmuch new, which is still running on the original maildir, and
|
|
# repeat this process.
