+Hi,\r
+\r
+this should allow me to do what I wish to accomplish. The message\r
+deletion is still a problem though, I can see two options at the moment:\r
+\r
+a) output during notmuch new to a hook or a list somewhere deleted files.\r
+ if list: notmuch will not handle this list, only append to it and\r
+the user must\r
+ purge it when it is safe to do so.\r
+\r
+ if hook: for my purposes I would just create a hook appending to the\r
+ list. as a minimum I think thread_id, message_id and revision number\r
+ should be included.\r
+\r
+\r
+b) maintain a full list of deleted / dead messages. a user initiated\r
+ purge can clean this from the database. a tag could be used for this,\r
+ so that clients can ignore unlinked/deleted/dead messages. this\r
+ differs from a 'deleted' message (IMAP/Maildir context) that has not\r
+ yet been expunged so there is confusion to be avoided.\r
+\r
+ a garbage collection function and interface must also be set up, but\r
+ this one is probably simple.\r
+\r
+\r
+in most cases I think a) would be sufficient, and probably much easier\r
+to do. it might be slow in cases where large amounts of messages have been\r
+deleted, but this is seldom the case for me at least.\r
+\r
+cheers, gaute\r
