2009-01-14git-notes: fix printing of multi-line notesLibravatar Tor Arne Vestbø1-6/+7
The line length was read from the same position every time, causing mangled output when printing notes with multiple lines. Also, adding new-line manually for each line ensures that we get a new-line between commits, matching git-log for commits without notes.

2009-01-11Speed up git notes lookupLibravatar Johannes Schindelin1-11/+102
To avoid looking up each and every commit in the notes ref's tree object, which is very expensive, speed things up by slurping the tree object's contents into a hash_map. The idea fo the hashmap singleton is from David Reiss, initial benchmarking by Jeff King. Note: the implementation allows for arbitrary entries in the notes tree object, ignoring those that do not reference a valid object. This allows you to annotate arbitrary branches, or objects.

2008-12-21Introduce commit notesLibravatar Johannes Schindelin1-0/+68
Commit notes are blobs which are shown together with the commit message. These blobs are taken from the notes ref, which you can configure by the config variable core.notesRef, which in turn can be overridden by the environment variable GIT_NOTES_REF. The notes ref is a branch which contains "files" whose names are the names of the corresponding commits (i.e. the SHA-1). The rationale for putting this information into a ref is this: we want to be able to fetch and possibly union-merge the notes, maybe even look at the date when a note was introduced, and we want to store them efficiently together with the other objects.
