From 909f52bd8c4bdfa11cd3e75e3d0959e0293689bd Mon Sep 17 00:00:00 2001 From: Carl Worth Date: Thu, 7 Jan 2010 18:26:31 -0800 Subject: lib: Implement versioning in the database and provide upgrade function. The recent support for renames in the database is our first time (since notmuch has had more than a single user) that we have a database format change. To support smooth upgrades we now encode a database format version number in the Xapian metadata. Going forward notmuch will emit a warning if used to read from a database with a newer version than it natively supports, and will refuse to write to a database with a newer version. The library also provides functions to query the database format version: notmuch_database_get_version to ask if notmuch wants a newer version than that: notmuch_database_needs_upgrade and a function to actually perform that upgrade: notmuch_database_upgrade --- lib/notmuch-private.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'lib/notmuch-private.h') diff --git a/lib/notmuch-private.h b/lib/notmuch-private.h index 27b1317d..f9adea72 100644 --- a/lib/notmuch-private.h +++ b/lib/notmuch-private.h @@ -238,6 +238,9 @@ _notmuch_message_gen_terms (notmuch_message_t *message, const char *prefix_name, const char *text); +void +_notmuch_message_upgrade_filename_storage (notmuch_message_t *message); + notmuch_status_t _notmuch_message_add_filename (notmuch_message_t *message, const char *filename); -- cgit v1.2.3
