To fully complete the ghost-on-removal-when-shared-thread-exists proposal, we need to clear all ghost messages when the last active message is removed from a thread. Amended by db: Remove the last test of T530, as it no longer makes sense if we are garbage collecting ghost messages.

test_description='thread breakage during reindexing
|
|
|
|
notmuch uses ghost documents to track messages we have seen references
|
|
to but have never seen. Regardless of the order of delivery, message
|
|
deletion, and reindexing, the list of ghost messages for a given
|
|
stored corpus should not vary, so that threads can be reassmebled
|
|
cleanly.
|
|
|
|
In practice, we accept a small amount of variation (and therefore
|
|
traffic pattern metadata leakage to be stored in the index) for the
|
|
sake of efficiency.
|
|
|
|
This test also embeds some subtests to ensure that indexing actually
|
|
works properly and attempted fixes to threading issues do not break
|
|
the expected contents of the index.'
