# 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.
