70 yes, i can. here's how to reproduce it on master:
\r
72 fire a `notmuch tag +TEST1 '*'`, which should block the db for a while.
\r
73 Then use the attached script to write to the index (this could make a nice
\r
74 second testcase for the bindings in case the test body is large enough).
\r
76 On master, the script fails like this:
\r
78 A Xapian exception occurred opening database: Unable to get write lock on
\r
79 /home/pazz/mail/.notmuch/xapian: already locked
\r
82 When you reset using `git reset e92b438f46a3a` (to 4winters first patch), t=
\r
84 fails like this, which is the intended behaviour:
\r
86 A Xapian exception occurred opening database: Unable to get write lock on /=
\r
87 home/pazz/mail/.notmuch/xapian: already locked
\r
88 Traceback (most recent call last):
\r
89 File "./p.py", line 3, in <module>
