notmuch/lib/database.cc, branch 0.24_rc1

lib: add mid: as a synonym for id:

2017-03-03T21:46:48Z

mid: is the url scheme suggested by URL 2392. We also plan to introduce more flexible searches for mid: than are possible with id: (in order not to break assumptions about the special behaviour of id:, e.g. identifying at most one message).

lib: regexp matching in 'subject' and 'from'

2017-03-03T21:46:48Z

the idea is that you can run % notmuch search subject:// % notmuch search from:// or % notmuch search subject:"your usual phrase search" % notmuch search from:"usual phrase search" This feature is only available with recent Xapian, specifically support for field processors is needed. It should work with bindings, since it extends the query parser. This is easy to extend for other value slots, but currently the only value slots are date, message_id, from, subject, and last_mod. Date is already searchable; message_id is left for a followup commit. This was originally written by Austin Clements, and ported to Xapian field processors (from Austin's custom query parser) by yours truly.

lib: create field processors from prefix table

2017-03-03T11:15:13Z

This is a bit more code than hardcoding the two existing field processors, but it should make it easy to add more.

lib: add _notmuch_database_reopen

2017-02-26T01:09:17Z

The main expected use is to recover from a Xapian::DatabaseChanged exception.

Merge branch 'release'

2017-02-23T13:08:15Z

Merge in g_hash_table read-after-free fix

lib: fix g_hash_table related read-after-free bug

2017-02-22T10:28:03Z

The two g_hash_table functions (insert, add) have different behaviour with respect to existing keys. g_hash_table_insert frees the new key, while g_hash_table_add (which is really g_hash_table_replace in disguise) frees the existing key. With this change 'ref' is live until the end of the function (assuming single-threaded access to 'hash'). We can't guarantee it will continue to be live in the future (i.e. there may be a future key duplication) so we copy it with the allocation context passed to parse_references (in practice this is the notmuch_message_t object whose parents we are finding). Thanks to Tomi for the simpler approach to the problem based on reading the fine glib manual.

lib: Let Xapian manage the memory for FieldProcessors

2017-02-19T02:18:06Z

It turns out this is exactly what release() is for; Xapian will deallocate the objects when it's done with them.

lib: merge internal prefix tables

2017-02-19T02:17:39Z

Replace multiple tables with some flags in a single table. This makes the code in notmuch_database_open_verbose a bit shorter, and it should also make it easier to add other options to fields, e.g. regexp searching.

lib: replace deprecated xapian call 'flush()' with 'commit()'

2016-10-25T21:13:52Z

This will make notmuch incompatible with Xapian before 1.1.0, which is more than 6 years old this point.

require xapian >= 1.2.6

2016-10-07T01:45:46Z

It seems that no-one tried to compile without Xapian compact support since March of 2015, since that's when I introduced a syntax error in that branch of the ifdef. Given the choice of maintaining this underused branch of code, or bumping the Xapian dependency to a version from 2011, it seems reasonable to do the latter.
