Hi notmuch developers,

I also had this database corruption, I waited for the fix to land
in notmuch 0.26.2, build it, moved the xapian directory away, did
a notmuch new and restored the tags from a dump.  But the problem
remains:

~$ xapian-check ~/Mail/.notmuch/xapian
docdata:
blocksize=8K items=10841 firstunused=75 revision=82 levels=1 root=2
B-tree checked okay
docdata table structure checked OK

termlist:
blocksize=8K items=1893162 firstunused=368983 revision=82 levels=3 root=177608
xapian-check: DatabaseError: 1 unused block(s) missing from the free list, first is 0


this is very similar to the old database which I had moved away:
~$ xapian-check ~/Mail/.notmuch/xapian-2018-04-29-00-22/
docdata:
blocksize=8K items=10863 firstunused=78 revision=59623 levels=1 root=2
B-tree checked okay
docdata table structure checked OK

termlist:
blocksize=8K items=1894648 firstunused=360821 revision=59623 levels=3 root=360580
xapian-check: DatabaseError: 1 unused block(s) missing from the free list, first is 0


Now I did notmuch compact and the database check says there are
no errors.


This seems to me as if the fix had not helped or there is another problem.


$ notmuch --version
notmuch 0.26.2+26~g9e158fb
~$ xapian-compact --version
xapian-compact - xapian-core 1.4.3

Thanks for developing notmuch, Gregor
