thread-based email index, search, and tagging https://git.notmuchmail.org/git/notmuch/atom?h=0.3.1 2010-03-09T17:22:29Z 2010-03-09T17:22:29Z Carl Worth cworth@cworth.org 2010-03-09T17:22:29Z urn:sha1:4e5d2f22db290a830c0267f34b519c6138af00ed We rename 'has_more' to 'valid' so that it can function whether iterating in a forward or reverse direction. We also rename 'advance' to 'move_to_next' to setup parallel naming with the proposed functions 'move_to_first', 'move_to_last', and 'move_to_previous'. 2010-01-09T19:18:27Z Carl Worth cworth@cworth.org 2010-01-09T19:18:27Z urn:sha1:ccf2e0cc4211c276da1db43cdca7ee11018c391d The WDF is the "within-document frequency" value for a particular term. It's intended to provide an indication of how frequent a term is within a document, (for use in computing relevance). Xapian's term generator already computes WDF values when we use that, (which we do for indexing all mail content). We don't use the term generator when adding single terms for things that don't actually appear in the mail document, (such as tags, the filename, etc.). In this case, the WDF value for these terms doesn't matter much. But Xapian's flint backend can be more efficient with changes to terms that don't affect the document "length". So there's a performance advantage for manipulating tags (with the flint backend) if the WDF of these terms is 0. 2010-01-07T18:19:44Z Carl Worth cworth@cworth.org 2010-01-07T18:19:44Z urn:sha1:f93b7218c3e2d11c5b3cdd4c367a42ca7a7ede77 Previously, many checks were deep in the library just before a cast operation. These have now been replaced with internal errors and new checks have instead been added at the beginning of all top-levelentry points requiring a read-write database. The new checks now also use a single function for checking and printing the error message. This will give us a convenient location to extend the check, (such as based on database version as well). 2010-01-06T22:35:11Z Carl Worth cworth@cworth.org 2010-01-06T22:35:11Z urn:sha1:957ae198e708dc901e3a8c89b7364c2bc75ce371 This will be convenient to avoid some special-casing in higher-level code. 2010-01-06T18:32:06Z Carl Worth cworth@cworth.org 2010-01-05T21:29:23Z urn:sha1:d807e28f43579ecc91aa40ae3e42760991c2f810 This new directory ojbect provides all the infrastructure needed to detect when files or directories are deleted or renamed. There's still code needed on top of this (within "notmuch new") to actually do that detection.
