Carlos Martín Nieto	795d8e9328	index: make sure to write cached subtrees if parent is invalidated ... If e.g. the root tree is invalidated, we still want to write out its children, since those may still have valid cache entries.	2014-10-10 19:43:42 +02:00
Carlos Martín Nieto	c2f8b21593	index: write out the tree cache extension ... Keeping the cache around after read-tree is only one part of the optimisation opportunities. In order to share the cache between program instances, we need to write the TREE extension to the index. Do so, taking the opportunity to rename 'entries' to 'entry_count' to match the name given in the format description. The included test is rather trivial, but works as a sanity check.	2014-10-10 19:43:42 +02:00
Carlos Martín Nieto	ee4db1c16e	index: add tests for the tree cache ... These test that we invalidate at the right levels and that we remove the tree cache when clearing the index.	2014-10-10 19:35:19 +02:00
