For example, if you already know it's a commit, and you know the \nparents, then yes, you can download it by basically saying that you want \nthat particular object and you already have the parents.\n\nBut in the general case, the answer is no.

When you do \"git ls-remote\" \non the remote repo, it will tell you both the tag object SHA and the \nobject SHA of the thing it points to, so you can then do a git protocol \nexchange where you do a \n\n\tfor_each_tag\n\t\t\"want \"\n\n\tfor_each_tag\n\t\t\"have \"\n\nand you'll get just the tag object back.\n\n\t\tLinus\n"},{"id":"20821","messageId":"loom.20060528T124835-757@post.gmane.org","threadId":"4314","inReplyTo":"Pine.LNX.4.64.0605271727110.5623@g5.osdl.org","subject":"Re: Remote git-cat-file?","fromName":"Elrond","fromEmail":"elrond+kernel.org@samba-tng.org","sentAt":"2006-05-28T10:57:43Z","receivedAt":"2006-05-28T10:57:43Z","isPatch":false,"sender":{"key":"elrond+kernel.org@samba-tng.org","avatar":null},"body":"Linus Torvalds osdl.org> writes:\n[...]\n> But in the general case, the answer is no.
