2011-09-30receive-pack: don't pass non-existent refs to post-{receive,update} hooksLibravatar Pang Yan Han1-0/+197
When a push specifies deletion of non-existent refs, the post post-receive and post-update hooks receive them as input/arguments. For instance, for the following push, where refs/heads/nonexistent is a ref which does not exist on the remote side: git push origin :refs/heads/nonexistent the post-receive hook receives from standard input: <null-sha1> SP <null-sha1> SP refs/heads/nonexistent and the post-update hook receives as arguments: refs/heads/nonexistent which does not make sense since it is a no-op. Teach receive-pack not to pass non-existent refs to the post-receive and post-update hooks. If the push only attempts to delete non-existent refs, these hooks are not even called. The update and pre-receive hooks are still notified about attempted deletion of non-existent refs to give them a chance to inspect the situation and act on it.

2010-05-20start_command: close cmd->err descriptor when fork/spawn failsLibravatar bert Dvornik1-1/+1
Fix the problem where the cmd->err passed into start_command wasn't being properly closed when certain types of errors occurr. (Compare the affected code with the clean shutdown code later in the function.) On Windows, this problem would be triggered if mingw_spawnvpe() failed, which would happen if the command to be executed was malformed (e.g. a text file that didn't start with a #! line). If cmd->err was a pipe, the failure to close it could result in a hang while the other side was waiting (forever) for either input or pipe close, e.g. while trying to shove the output into the side band. On msysGit, this problem was causing a hang in t5516-fetch-push.

2010-04-19receive-pack: detect aliased updates which can occur with symrefsLibravatar Jay Soffian1-0/+49
When pushing to a remote repo the sending side filters out aliased updates (e.g., foo:baz bar:baz). However, it is not possible for the sender to know if two refs are aliased on the receiving side via symrefs. Here is one such scenario: $ git init origin $ (cd origin && touch file && git add file && git commit -a -m intial) $ git clone --bare origin origin.git $ rm -rf origin $ git clone origin.git client $ git clone --mirror client backup.git && $ (cd backup.git && git remote set-head origin --auto) $ (cd client && git remote add --mirror backup ../backup.git && echo change1 > file && git commit -a -m change1 && git push origin && git push backup ) The push to backup fails with: Counting objects: 5, done. Writing objects: 100% (3/3), 244 bytes, done. Total 3 (delta 0), reused 0 (delta 0) Unpacking objects: 100% (3/3), done. error: Ref refs/remotes/origin/master is at ef3... but expected 262... remote: error: failed to lock refs/remotes/origin/master To ../backup.git 262cd57..ef307ff master -> master 262cd57..ef307ff origin/HEAD -> origin/HEAD ! [remote rejected] origin/master -> origin/master (failed to lock) error: failed to push some refs to '../backup.git' The reason is that refs/remotes/origin/HEAD is a symref to refs/remotes/origin/master, but it is not possible for the sending side to unambiguously know this. This commit fixes the issue by having receive-pack ignore any update to a symref whose target is being identically updated. If a symref and its target are being updated inconsistently, then the update for both fails with an error message ("refusing inconsistent update...") to help diagnose the situation.

This configuration option allows systematically rewriting fetch-only URLs to push-capable URLs when used with push. For instance: [url "ssh://example.org/"] pushInsteadOf = "git://example.org/" This will allow clones of "git://example.org/path/to/repo" to subsequently push to "ssh://example.org/path/to/repo", without manually configuring pushurl for that remote.

2009-07-29Refuse updating the current branch in a non-bare repository via pushLibravatar Junio C Hamano1-0/+1
This makes git-push refuse pushing into a non-bare repository to update the current branch by default. To help people who are used to be able to do this (and later "reset --hard" it in some other way), an error message is issued when this refusal is triggered, instructing how to resurrect the old behaviour. Hosting sites that do not give the users direct access to customize their repositories (e.g. repo.or.cz, gitorious, github etc.) may further want to explicitly set the configuration variable to "refuse" for their customers' repositories.

2008-11-09receive-pack: detect push to current branch of non-bare repoLibravatar Jeff King1-0/+37
Pushing into the currently checked out branch of a non-bare repository can be dangerous; the HEAD then loses sync with the index and working tree, and it looks in the receiving repo as if the pushed changes have been reverted in the index (since they were never there in the first place). This patch adds a safety valve that checks for this condition and either generates a warning or denies the update. We trigger the check only on a non-bare repository, since a bare repo does not have a working tree (and in fact, pushing to the HEAD branch is a common workflow for publishing repositories). The behavior is configurable via receive.denyCurrentBranch, defaulting to "warn" so as not to break existing setups (though it may, after a deprecation period, switch to "refuse" by default). For users who know what they are doing and want to silence the warning (e.g., because they have a post-receive hook that reconciles the HEAD and working tree), they can turn off the warning by setting it to false or "ignore".

2008-11-09t5516: refactor oddball testsLibravatar Jeff King1-29/+21
t5516 sets up some utility functions for starting each test with a clean slate. However, there were a few tests added that do not use these functions, but instead make their own repositories. Let's bring these in line with the rest of the tests. Not only do we reduce the number of lines, but these tests will benefit from any further enhancements to the utility scripts. The conversion is pretty straightforward. Most of the tests created a parent/child clone relationship, for which we now use 'testrepo' as the parent. One test looked in testrepo, but relied on previous tests to have set it up; it now sets up testrepo explicitly, which makes it a bit more robust to changes in the script, as well.

This fixes the remainder of the issues where the test script itself is at fault for failing when the git checkout path contains whitespace or other shell metacharacters. The majority of git svn tests used the idiom test_expect_success "title" "test script using $svnrepo" These were changed to have the test script in single-quotes: test_expect_success "title" 'test script using "$svnrepo"' which unfortunately makes the patch appear larger than it really is. One consequence of this change is that in the verbose test output the value of $svnrepo (and in some cases other variables, too) is no longer expanded, i.e. previously we saw * expecting success: test script using /path/to/git/t/trash/svnrepo but now it is: * expecting success: test script using "$svnrepo" Signed-off-by: Bryan Donlan <bdonlan@fushizen.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2008-04-24push: allow unqualified dest refspecs to DWIMLibravatar Jeff King1-0/+40
Previously, a push like: git push remote src:dst would go through the following steps: 1. check for an unambiguous 'dst' on the remote; if it exists, then push to that ref 2. otherwise, check if 'dst' begins with 'refs/'; if it does, create a new ref 3. otherwise, complain because we don't know where in the refs hierarchy to put 'dst' However, in some cases, we can guess about the ref type of 'dst' based on the ref type of 'src'. Specifically, before complaining we now check: 2.5. if 'src' resolves to a ref starting with refs/heads or refs/tags, then prepend that to 'dst' So now this creates a new branch on the remote, whereas it previously failed with an error message: git push master:newbranch Note that, by design, we limit this DWIM behavior only to source refs which resolve exactly (including symrefs which resolve to existing refs). We still complain on a partial destination refspec if the source is a raw sha1, or a ref expression such as 'master~10'.

2007-11-30receive-pack: allow deletion of corrupt refsLibravatar Johannes Schindelin1-3/+42
Occasionally, in some setups (*cough* forks on repo.or.cz *cough*) some refs go stale, e.g. when the forkee rebased and lost some objects needed by the fork. The quick & dirty way to deal with those refs is to delete them and push them again. However, git-push first would first fetch the current commit name for the ref, would receive a null sha1 since the ref does not point to a valid object, then tell receive-pack that it should delete the ref with this commit name. delete_ref() would be subsequently be called, and check that resolve_ref() (which does _not_ check for validity of the object) returns the same commit name. Which would fail. The proper fix is to avoid corrupting repositories, but in the meantime this is a good fix in any case. Incidentally, some instances of "cd .." in the test cases were fixed, so that subsequent test cases run in t/trash/ irrespective of the outcome of the previous test cases.

This commit changes the rules for resolving refspecs to match the rules for resolving refs in rev-parse. git-rev-parse uses clear rules to resolve a short ref to its full name, which are well documented. The rules for resolving refspecs documented in git-send-pack were less strict and harder to understand. This commit replaces them by the rules of git-rev-parse. The unified rules are easier to understand and better resolve ambiguous cases. You can now push from a repository containing several branches ending on the same short name. Note, this may break existing setups. For example, "master" will no longer resolve to "origin/master" even when there is no other "master" elsewhere.

Earlier, when the local repository has a branch "frotz" and the remote repository has a tag "frotz" (but not branch "frotz"), "git-push frotz" mistakenly updated the tag at the remote side.

2007-06-09remote.c: fix "git push" weak match disambiguationLibravatar Junio C Hamano1-0/+112
When "git push A:B" is given, and A (or B) is not a full refname that begins with refs/, we require an unambiguous match with an existing ref. For this purpose, a match with a local branch or a tag (i.e. refs/heads/A and refs/tags/A) is called a "strong match", and any other match is called a "weak match". A partial refname is unambiguous when there is only one strong match with any number of weak matches, or when there is only one weak match and no other match. However, as reported by Sparse with Ramsay Jones recently, count_refspec_match() function had a bug where a variable in an inner block masked a different variable of the same name, which caused the weak matches to be ignored. This fixes it, and adds tests for the fix. Signed-off-by: Junio C Hamano <gitster@pobox.com>
