I remember writing a prototype, but never submitting a proper patch: http://thread.gmane.org/gmane.comp.version-control.darcs.devel/5228/focus=5291 /------ | I'm working on a filecache (FilePath -> [PatchId] mapping) to speed up | annotate file and changes file. You can lookup if a patch touches | a certain file without traversing all the patches. Then you only have | to parse and apply the subset of patches that change the file for the | annotation info. | [...] | This info is stored in _darcs/filecache/≤sha1 of filename> as | Touch <patchid> | RenamedTo <patchid> <new filename> | RenamedFrom <patchid> <old filename> | | (RenamedFrom for backwards reading). | | For now, i added a optimize --filecache option to create the filecache and | read the filecache for annotate and changes. I'm using a Map String () for | now that uses the patchid as key and is used for checking if a certain | patch has to be applied. I don't use Population any more for the the single | file case if there is a filecache, but it's still used for annotate | directory. \----- I'll see if I can dig up the old code and how much of it could still be used with current darcs. version.
