pushed, thanks.

Now somewhere I have patches for compatibility with xapian 1.5 that I
think was blocked on that...

[PATCH v2] build: drop support for xapian versions less than 1.4

2020-04-21 Thread Tomi Ollila
Xapian 1.4 is over 3 years old now (1.4.0 released 2016-06-24),
and 1.2 has been deprecated in Notmuch version 0.27 (2018-06-13).

Xapian 1.4 supports compaction, field processors and retry locking;
conditionals checking compaction and field processors were removed
but user may want to disable retry locking at configure time so it
is kept.

This is v2 of id:2020022955.6795-1-tomi.oll...@iki.fi

Change to v1: restored known_broken indication of that one test which
*is* known broken when tried with xapian 1.4...

doc/man7/notmuch-search-terms.rst was not changed in this commit --
I did not fully understand what was it saying...
