This is intended to fix the slow behaviour of "notmuch new" (and possibly "notmuch reindex") when large numbers of files are deleted. The underlying issue [1] seems to be the Xapian glass backend spending a large amount of time in db.has_positions when running queries with large-ish amounts of unflushed changes. This commit removes two uses of Xapian queries [2], and replaces them with an approximation of what Xapian would do after optimizing the queries. This avoids the calls to has_positions (which are in any case un-needed because we are only using boolean terms here). [1] Thanks to "andres" on IRC for narrowing down the performance bottleneck. [2] Thanks to Olly Betts of Xapian fame for talking me a through a fix that does not require people to update Xapian. |
