#include "cache.h"
git-send-pack: verify that sender is a proper superset of receiver This should make sure that if you have multiple people pushing to the same tree, they cannot overwrite each others work, but have to merge before being able to update the common reference tree.
2005-07-19 19:03:47 +08:00
#include "commit.h"
Fix send-pack for non-commitish tags. Again I left the v2.6.11-tree tag behind. My bad. This commit makes sure that we do not barf when pushing a ref that is a non-commitish tag. You can update a remote ref under the following conditions: * You can always use --force. * Creating a brand new ref is OK. * If the remote ref is exactly the same as what you are pushing, it is OK (nothing is pushed). * You can replace a commitish with another commitish which is a descendant of it, if you can verify the ancestry between them; this and the above means you have to have what you are replacing. * Otherwise you cannot update; you need to use --force.

#include "tag.h"
Teach 'git-send-pack' to send new branches and tags. The protocol always supported it, but send-pack didn't actually know how to tell the other side about a new branch/tag. NOTE! You'll have to name it explicitly on the command line: if you don't name any branches, git-send-pack will default to the branches that already exist.
2005-07-09 04:58:40 +08:00

Exec git programs without using PATH. The git suite may not be in PATH (and thus programs such as git-send-pack could not exec git-rev-list). Thus there is a need for logic that will locate these programs. Modifying PATH is not desirable as it result in behavior differing from the user's intentions, as we may end up prepending "/usr/bin" to PATH. - git C programs will use exec*_git_cmd() APIs to exec sub-commands. - exec*_git_cmd() will execute a git program by searching for it in the following directories: 1. --exec-path (as used by "git") 2. The GIT_EXEC_PATH environment variable. 3. $(gitexecdir) as set in Makefile (default value $(bindir)). - git wrapper will modify PATH as before to enable shell scripts to invoke "git-foo" commands. Ideally, shell scripts should use the git wrapper to become independent of PATH, and then modifying PATH will not be necessary.

git-send-pack: verify that sender is a proper superset of receiver This should make sure that if you have multiple people pushing to the same tree, they cannot overwrite each others work, but have to merge before being able to update the common reference tree.

Fix send-pack for non-commitish tags. Again I left the v2.6.11-tree tag behind. My bad. This commit makes sure that we do not barf when pushing a ref that is a non-commitish tag. You can update a remote ref under the following conditions: * You can always use --force. * Creating a brand new ref is OK. * If the remote ref is exactly the same as what you are pushing, it is OK (nothing is pushed). * You can replace a commitish with another commitish which is a descendant of it, if you can verify the ancestry between them; this and the above means you have to have what you are replacing. * Otherwise you cannot update; you need to use --force.

Remove TYPE_* constant macros and use object_type enums consistently. This updates the type-enumeration constants introduced to reduce the memory footprint of "struct object" to match the type bits already used in the packfile format, by removing the former (i.e. TYPE_* constant macros) and using the latter (i.e. enum object_type) throughout the code for consistency. Eventually we can stop passing around the "type strings" entirely, and this will help - no confusion about two different integer enumeration.

Convert memcpy(a,b,20) to hashcpy(a,b). This abstracts away the size of the hash values when copying them from memory location to memory location, much as the introduction of hashcmp abstracted away hash value comparsion. A few call sites were using char* rather than unsigned char* so I added the cast rather than open hashcpy to be void*. This is a reasonable tradeoff as most call sites already use unsigned char* and the existing hashcmp is also declared to be unsigned char*. [jc: Splitted the patch to "master" part, to be followed by a patch for merge-recursive.c which is not in "master" yet.

Improve git-peek-remote This makes git-peek-remote able to basically do everything that git-ls-remote does (but obviously just for the native protocol, so no http[s]: or rsync: support). The default behaviour is the same, but you can now give a mixture of "--refs", "--tags" and "--heads" flags, where "--refs" forces git-peek-remote to only show real refs (ie none of the fakey tag lookups, but also not the special pseudo-refs like HEAD and MERGE_HEAD). The "--tags" and "--heads" flags respectively limit the output to just regular tags and heads, of course. You can still also ask to limit them by name too. You can combine the flags, so git peek-remote --refs --tags . will show all local _true_ tags, without the generated tag lookups (compare the output without the "--refs" flag). And "--tags --heads" will show both tags and heads, but will avoid (for example) any special refs outside of the standard locations. I'm also planning on adding a "--ignore-local" flag that allows us to ask it to ignore any refs that we already have in the local tree, but that's an independent thing. All this is obviously gearing up to making "git fetch" cheaper. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

Make "git-send-pack" less verbose by default It used to make sense to have git-send-pack talk about the things it sent when (a) it was a new program and (b) nobody had a lot of tags and branches. These days, it's just distracting to see tons of 'refs/tags/xyz': up-to-date ... when updating a remote repo. So shut it up by default, and add a "--verbose" flag for those who really want to see it. Also, since this makes he case of everything being up-to-date just totally silent, make it say "Everything up-to-date" if no refs needed updating.

This is a reasonable tradeoff as most call sites already use unsigned char* and the existing hashcmp is also declared to be unsigned char*.

Teach 'git-send-pack' to send new branches and tags. The protocol always supported it, but send-pack didn't actually know how to tell the other side about a new branch/tag. NOTE! You'll have to name it explicitly on the command line: if you don't name any branches, git-send-pack will default to the branches that already exist.

send-pack/receive-pack: allow errors to be reported back to pusher. This updates the protocol between git-send-pack/git-receive-pack in a backward compatible way to allow failures at the receiving end to be propagated back to the sender. Most notably, versions of git-push before this could not notice if the update hook on the receiving end refused to update the ref for its own policy reasons.

Make "git-send-pack" less verbose by default It used to make sense to have git-send-pack talk about the things it sent when (a) it was a new program and (b) nobody had a lot of tags and branches. These days, it's just distracting to see tons of 'refs/tags/xyz': up-to-date ... when updating a remote repo. So shut it up by default, and add a "--verbose" flag for those who really want to see it. Also, since this makes he case of everything being up-to-date just totally silent, make it say "Everything up-to-date" if no refs needed updating.

Do ref matching on the sender side rather than on receiver This makes the receiver always send a full list of valid refs, which will allow us to do better packs, as well as handle creation of new refs. Eventually. Right now we just moved the matching and enabled it. So now you can do git-send-pack host:path branch1 branch2 to only send branches "branch1" and "branch2".
