Linus Torvalds	cf219196a8	Fix up progress report for off-by-one error We used to print the index of the object we unpacked, not how many we had unpacked. Which caused slightly confusing progress reports like 100% (2/3) done rather than the more obvious "3/3" for 100% ;)	20 years ago
Linus Torvalds	d36f7b805e	git-unpack-objects: show progress report by default This ends up being very calming for big "git clone"s, since otherwise you just get very frustrated with a long silence, wondering whether it's working at all. Use "-q" to quiet it down. Now if we could just do the same for the initial "figure out what to pack" phase, which can also be quite slow if the other end is busy (or not packed and not in cache)...	20 years ago
Linus Torvalds	291ec0f2d2	Don't special-case a zero-sized compression. zlib actually writes a header for that case, and while ignoring that header will get us the right data, it will also end up messing up our stream position. So we actually want zlib to "uncompress" even an empty object.	20 years ago
Linus Torvalds	dddafffef6	Re-instate dry-run logic in git-unpack-objects It can no longer be as verbose, since it doesn't have a good way to resolve deltas (now that it is purely streaming, it cannot seek around to read the objects a delta is based on). But it can check that the thing unpacks cleanly at least as far as pack syntax goes - all the objects uncompress cleanly, and the pack has the right final SHA1.	20 years ago
Linus Torvalds	cca7081a93	Clean up git-unpack-objects a bit I'd like to add back the "dry-run" thing, but it turns out that to do it well, I'd have to keep all the object data in memory (which is not acceptable). So I'll clean it up a bit and make it do as many checks as it can.	20 years ago
Linus Torvalds	01247d8742	Make git pack files use little-endian size encoding This makes it match the new delta encoding, and admittedly makes the code easier to follow. This also updates the PACK file version to 2, since this (and the delta encoding change in the previous commit) are incompatible with the old format.	20 years ago
Linus Torvalds	67e5a5ece4	git-unpack-objects: re-write to read from stdin It gets a bit more complicated to unpack in a streaming environment, but here it is. The rewrite is actually a lot cleaner in other ways, it's just a bit more subtle.	20 years ago
Junio C Hamano	e1ddc97684	[PATCH] Fix unpack-objects for header length information. Standalone unpack-objects command was not adjusted for header length encoding change when dealing with deltified entry. This fixes it.

Linus Torvalds	a733cb606f	Change pack file format. Hopefully for the last time. This also adds a header with a signature, version info, and the number of objects to the pack file. It also encodes the file length and type more efficiently.	20 years ago
Linus Torvalds	a69d094366	Teach packing about "tag" objects (And teach sha1_file and unpack-object know how to unpack them too, of course)	20 years ago
Linus Torvalds	e18088451d	csum-file interface updates: return resulting SHA1 Also, make the writing of the SHA1 as a end-header be conditional: not every user will necessarily want to write the SHA1 to the file itself, even though current users do (but we migh end up using the same helper functions for the object files themselves, that don't do this). This also makes the packed index file contain the SHA1 of the packed data file at the end (just before its own SHA1). That way you can validate the pairing of the two if you want to.	20 years ago
Linus Torvalds	c38138cd78	git-pack-objects: write the pack files with a SHA1 csum We want to be able to check their integrity later, and putting the sha1-sum of the contents at the end is a good thing. The writing routines are generic, so we could try to re-use them for the index file, instead of having the same logic duplicated. Update unpack-objects to know about the extra 20 bytes at the end of the index.	20 years ago
Linus Torvalds	641e1cac73	git-unpack-objects: start removing debug output At least the least interesting one.	20 years ago
Linus Torvalds	c4fb06c0d0	Fix object packing/unpacking. This actually successfully packed and unpacked a git archive down to 1.3MB (17MB unpacked). Right now unpacking is way too noisy, lots of debug messages left.	20 years ago
Junio C Hamano	8ee378a0f0	[PATCH] Finish initial cut of git-pack-object/git-unpack-object pair. This finishes the initial round of git-pack-object / git-unpack-object pair. They are now good enough to be used as a transport medium: - Fix delta direction in pack-objects; the original was computing delta to create the base object from the object to be squashed, which was quite unfriendly for unpacker ;-). - Add a script to test the very basics. - Implement unpacker for both regular and deltified objects.

Linus Torvalds	7453695831	git-unpack-objects: start parsing the actual packed data So far we just print out the type and size.	20 years ago
Linus Torvalds	bad50dc80f	First cut at git-unpack-objects So far it just reads the header and generates the list of objects. It also sorts them by the order they are written in the pack file, since that ends up being the same order we got them originally, and is thus "most recent first".	20 years ago
