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