2013-02-04Verify Content-Type from smart HTTP serversLibravatar Shawn Pearce4-0/+22
Before parsing a suspected smart-HTTP response verify the returned Content-Type matches the standard. This protects a client from attempting to process a payload that smells like a smart-HTTP server response. JGit has been doing this check on all responses since the dawn of time. I mistakenly failed to include it in git-core when smart HTTP was introduced. At the time I didn't know how to get the Content-Type from libcurl. I punted, meant to circle back and fix this, and just plain forgot about it. Signed-off-by: Shawn Pearce <spearce@spearce.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Minimal test case: # on NetBSD with /bin/sh $ a() { echo $#-$1-$2; } $ t="x"; a "${t:+$t}" 1-x- $ t="x y"; a "${t:+$t}" 2-x-y $ t="x y"; a "${t:+x y}" 1-x y- # and with bash $ t="x y"; a "${t:+$t}" 1-x y- $ t="x y"; a "${t:+x y}" 1-x y- This may be a bug in the shell, but here's a simple workaround: Construct the description string first and store it in a variable, and then use that to call test_expect_success().

2013-01-06run-command: encode signal death as a positive integerLibravatar Jeff King1-1/+1
When a sub-command dies due to a signal, we encode the signal number into the numeric exit status as "signal - 128". This is easy to identify (versus a regular positive error code), and when cast to an unsigned integer (e.g., by feeding it to exit), matches what a POSIX shell would return when reporting a signal death in $? or through its own exit code. So we have a negative value inside the code, but once it passes across an exit() barrier, it looks positive (and any code we receive from a sub-shell will have the positive form). E.g., death by SIGPIPE (signal 13) will look like -115 to us in inside git, but will end up as 141 when we call exit() with it. And a program killed by SIGPIPE but run via the shell will come to us with an exit code of 141. Unfortunately, this means that when the "use_shell" option is set, we need to be on the lookout for _both_ forms. We might or might not have actually invoked the shell (because we optimize out some useless shell calls). If we didn't invoke the shell, we will will see the sub-process's signal death directly, and run-command converts it into a negative value. But if we did invoke the shell, we will see the shell's 128+signal exit status. To be thorough, we would need to check both, or cast the value to an unsigned char (after checking that it is not -1, which is a magic error value). Fortunately, most callsites do not care at all whether the exit was from a code or from a signal; they merely check for a non-zero status, and sometimes propagate the error via exit(). But for the callers that do care, we can make life slightly easier by just using the consistent positive form. This actually fixes two minor bugs: 1. In launch_editor, we check whether the editor died from SIGINT or SIGQUIT. But we checked only the negative form, meaning that we would fail to notice a signal death exit code which was propagated through the shell. 2. In handle_alias, we assume that a negative return value from run_command means that errno tells us something interesting (like a fork failure, or ENOENT). Otherwise, we simply propagate the exit code. Negative signal death codes confuse us, and we print a useless "unable to run alias 'foo': Success" message. By encoding signal deaths using the positive form, the existing code just propagates it as it would a normal non-zero exit code. The downside is that callers of run_command can no longer differentiate between a signal received directly by the sub-process, and one propagated. However, no caller currently cares, and since we already optimize out some calls to the shell under the hood, that distinction is not something that should be relied upon by callers. Fix the same logic in t/test-terminal.perl for consistency [jc: raised by Jonathan in the discussion].

2013-01-05clone: support atomic operation with --separate-git-dirLibravatar Jens Lehmann1-1/+11
Since b57fb80a7d (init, clone: support --separate-git-dir for .git file) git clone supports the --separate-git-dir option to create the git dir outside the work tree. But when that option is used, the git dir won't be deleted in case the clone fails like it would be without this option. This makes clone lose its atomicity as in case of a failure a partly set up git dir is left behind. A real world example where this leads to problems is when "git submodule update" fails to clone a submodule and later calls to "git submodule update" stumble over the partially set up git dir and try to revive the submodule from there, which then fails with a not very user friendly error message. Fix that by updating the junk_git_dir variable (used to remember if and what git dir should be removed in case of failure) to the new value given with the --seperate-git-dir option. Also add a test for this to t5600 (and while at it fix the former last test to not cd into a directory to test for its existence but use "test -d" instead).

2013-01-03merge: Honor prepare-commit-msg return codeLibravatar Antoine Pelisse1-0/+14
65969d4 (merge: honor prepare-commit-msg hook, 2011-02-14) tried to make "git commit" and "git merge" consistent, because a merge that required user assistance has to be concluded with "git commit", but back then only "git commit" triggered prepare-commit-msg hook. When it added a call to run the prepare-commit-msg hook, however, it forgot to check the exit code from the hook like "git commit" does, and ended up replacing one inconsistency with another. When prepare-commit-msg hook that is run from "git merge" exits with a non-zero status, abort the commit.

2013-01-03tests: turn on test-lint by defaultLibravatar Jeff King1-0/+1
The test Makefile knows about a few "lint" checks for common errors. However, they are not enabled as part of "make test" by default, which means that many people do not bother running them. Since they are both quick to run and accurate (i.e., no false positives), there should be no harm in turning them on and helping submitters catch errors earlier. We could just set: TEST_LINT = test-lint to enable all tests. But that would be unnecessarily annoying later on if we add slower or less accurate tests that should not be part of the default.

2012-12-28Use longer alias names in subdirectory testsLibravatar Aaron Schrab1-6/+6
When testing aliases in t/t1020-subdirectory.sh use longer names so that they're less likely to conflict with a git-* command somewhere in the $PATH. I have a git-ss command in my path which prevents the 'ss' alias from being used. This command will always fail for git.git, causing the test to fail. Even if the command succeeded, that would be a false success for the test since the alias wasn't actually used. A longer, more descriptive name will make it much less likely that somebody has a command in their $PATH which will shadow the alias created for the test. While here, use a longer name for the 'test' alias as well since that is also short and meaningful enough to make it not unlikely that somebody would have a command in their $PATH which will shadow that as well.

Intent-to-add entries used to forbid writing trees so it was not a problem. After commit 3f6d56d (commit: ignore intent-to-add entries instead of refusing - 2012-02-07), we can generate trees from an index with i-t-a entries. However, the commit forgets to invalidate all paths leading to i-t-a entries. With fully valid cache-tree (e.g. after commit or write-tree), diff operations may prefer cache-tree to index and not see i-t-a entries in the index, because cache-tree does not have them.

2012-12-11fetch: ignore wildcarded refspecs that update local symbolic refsLibravatar Junio C Hamano1-0/+42
In a repository cloned from somewhere else, you typically have a symbolic ref refs/remotes/origin/HEAD pointing at the 'master' remote-tracking ref that is next to it. When fetching into such a repository with "git fetch --mirror" from another repository that was similarly cloned, the implied wildcard refspec refs/*:refs/* will end up asking to update refs/remotes/origin/HEAD with the object at refs/remotes/origin/HEAD at the remote side, while asking to update refs/remotes/origin/master the same way. Depending on the order the two updates happen, the latter one would find that the value of the ref before it is updated has changed from what the code expects. When the user asks to update the underlying ref via the symbolic ref explicitly without using a wildcard refspec, e.g. "git fetch $there refs/heads/master:refs/remotes/origin/HEAD", we should still let him do so, but when expanding wildcard refs, it will result in a more intuitive outcome if we simply ignore local symbolic refs. As the purpose of the symbolic ref refs/remotes/origin/HEAD is to follow the ref it points at (e.g. refs/remotes/origin/master), its value would change when the underlying ref is updated. Earlier commit da3efdb (receive-pack: detect aliased updates which can occur with symrefs, 2010-04-19) fixed a similar issue for "git push". Signed-off-by: Junio C Hamano <gitster@pobox.com>
