Nicolas Pitre	83ba99bc8c	[PATCH] fix scalability problems with git-deltafy-script Current version would spin forever and exhaust memory while attempting to sort all files from all revisions at once, until it dies before even doing any real work. This is especially noticeable when used on a big repository like the imported bkcvs repo for the Linux kernel. This patch allows for batching the sort to put a bound on needed resources and making progress early, as well as including some small cleanups.

Nicolas Pitre	53d4b46085	[PATCH] mkdelta enhancements (take 2) Although it was described as such, git-mkdelta didn't really attempt to find the best delta against any previous object in the list, but was only able to create a delta against the preceeding object. This patch reworks the code to fix that limitation and hopefully makes it a bit clearer than before, including fixing the delta loop detection which was broken. This means that git-mkdelta sha1 sha2 sha3 sha4 sha5 sha6 will now create a sha2 delta against sha1, a sha3 delta against either sha2 or sha1 and keep the best one, a sha4 delta against either sha3, sha2 or sha1, etc. The --max-behind argument limits that search for the best delta to the specified number of previous objects in the list. If no limit is specified it is unlimited (note: it might run out of memory with long object lists). Also added a -q (quiet) switch so it is possible to have 3 levels of output: -q for nothing, -v for verbose, and if none of -q nor -v is specified then only actual changes on the object database are shown. Finally the git-deltafy-script has been updated accordingly, and some bugs fixed (thanks to Stephen C. Tweedie for spotting them). This version has been toroughly tested and I think it is ready for public consumption. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>	20 years ago
Nicolas Pitre	587e49405b	[PATCH] adjust git-deltafy-script to the new diff-tree output format Also prevent 'sort' from sorting on the sha1 which was screwing the history listing. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>	20 years ago
Nicolas Pitre	e002a16ba5	[PATCH] delta creation This adds the ability to actually create delta objects using a new tool: git-mkdelta. It uses an ordered list of potential objects to deltafy against earlier objects in the list. A cap on the depth of delta references can be provided as well, otherwise the default is to not have any limit. A limit of 0 will also undeltafy any given object. Also provided is the beginning of a script to deltafy an entire repository. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>	20 years ago
