Junio C Hamano	f1f0a2be9f	Be more careful tangling object chains while marking commits. Also Johannes noticed we use parse_object to look up if we know that object already -- we should just ask the in-core object registry with lookup_object() for that.

Junio C Hamano	4dab94d52e	Do not feed rev-list an invalid SHA1 expression. The previous round to optimize fetch-pack has a small bug that feeds SHA1^ ("parent commit") before making sure SHA1 is actually a commit (or a tag that eventually dereferences to a commit). Also it did not help culling the known-to-be-common parents if the common one was a merge. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Johannes Schindelin	0a8944dd48	[PATCH] Do not send "want" lines for complete objects It was all good and well to check if all remote refs are complete (local refs or descendants thereof), but we can just as easily use the same information to avoid sending "want" lines just for the complete objects in the case that not all remote refs are complete (or their names differ). Also, git-fetch-pack does not have to ask for descendants of remote refs which are complete (for now, git-rev-list is told to ignore only the first parent). That change also eliminates a code path where a popen()ed handle was not pclose()ed.

Junio C Hamano	49bb805e69	Do not ask for objects known to be complete. On top of optimization by Linus not to ask refs that already match, we can walk our refs and not issue "want" for things that are known to be reachable from them. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago

Linus Torvalds	2759cbc774	git-fetch-pack: avoid unnecessary zero packing If everything is up-to-date locally, we don't need to even ask for a pack-file from the remote, or try to unpack it. This is especially important for tags - since the pack-file common commit logic is based purely on the commit history, it will never be able to find a common tag, and will thus always end up re-fetching them. Especially notably, if the tag points to a non-commit (eg a tagged tree), the pack-file would be unnecessarily big, just because it cannot any most recent common point between commits for pruning. Short-circuiting the case where we already have that reference means that we avoid a lot of these in the common case. NOTE! This only matches remote ref names against the same local name, which works well for tags, but is not as generic as it could be. If we ever need to, we could match against _any_ local ref (if we have it, we have it), but this "match against same name" is simpler and more efficient, and covers the common case. Renaming of refs is common for branch heads, but since those are always commits, the pack-file generation can optimize that case. In some cases we might still end up fetching pack-files unnecessarily, but this at least avoids the re-fetching of tags over and over if you use a regular git fetch --tags ... which was the main reason behind the change.

Junio C Hamano	1a7141ff28	Ignore funny refname sent from remote This allows the remote side (most notably, upload-pack) to show additional information without affecting the downloader. Peek-remote does not ignore them -- this is to make it useful for Pasky's automatic tag following. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Junio C Hamano	33b8303466	fetch-pack: start multi-head pulling. This is a beginning of resurrecting the multi-head pulling support for git-fetch-pack command. The git-fetch-script wrapper still only knows about fetching a single head, without renaming, so it is not very useful unless you directly call git-fetch-pack itself yet. It also fixes a longstanding obsolete description of how the command discovers the list of local commits.	20 years ago
Linus Torvalds	d1c133f5d4	Merge three separate "fetch refs" functions It really just boils down to one "get_remote_heads()" function, and a common "struct ref" structure definition.	20 years ago

Linus Torvalds	516236ce3f	Get rid of nasty utf-8 characters in printout Oh, well.. FC4 has UTF-8 as the default environment, and I applaud that, but then it sometimes results in these characters that aren't actually visible as a problem.	20 years ago
Linus Torvalds	85c414b5e0	git-fetch-pack: close output fd after dup'ing the input With the socket case, the input and output fd's might end up being the same, so we want to dup the other before we close either of them.	20 years ago
Linus Torvalds	41cb7488b9	Move "get_ack()" to common git_connect functions git-clone-pack will want it too. Soon.	20 years ago
Linus Torvalds	4f7770c87c	Remove multi-head support from fetch-pack It was a misguided attempt to mix fetching and cloning. I'll make a separate clone thing.	20 years ago
Linus Torvalds	723c31fea2	Add "git_path()" and "head_ref()" helper functions. "git_path()" returns a static pathname pointer into the git directory using a printf-like format specifier. "head_ref()" works like "for_each_ref()", except for just the HEAD.	20 years ago
Linus Torvalds	75bfc6c232	Make git-fetch-pack actually do all the unpacking etc. It returns the result SHA1 on stdout, so you can do remote=$(git-fetch-pack host:dir branchname) and it will unpack the objects and "remote" will be the SHA1 name of the branch on the other side. You can then save that off, or merge it, or whatever.	20 years ago
Linus Torvalds	fb9040cc83	Make git-fetch-pack and git-upload-pack negotiate needs/haves fully Now the only piece missing is actually generating the pack-file.	20 years ago
Linus Torvalds	def88e9afb	Commit first cut at "git-fetch-pack" It's meant to be used by "git fetch" for the local and ssh case. It doesn't actually do the fetching now, but it does discover the common commit point.	20 years ago
