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

[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.

[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.
