2012-02-23merge: do not trust fstat(2) too much when checking interactivenessLibravatar Junio C Hamano1-1/+1
The heuristic used by "git merge" to decide if it automatically gives an editor upon clean automerge is to see if the standard input and the standard output is the same device and is a tty, we are in an interactive session. "The same device" test was done by comparing fstat(2) result on the two file descriptors (and they must match), and we asked isatty() only for the standard input (we insist that they are the same device and there is no point asking tty-ness of the standard output). The stat(2) emulation in the Windows port however does not give a usable value in the st_ino field, so even if the standard output is connected to something different from the standard input, "The same device" test may incorrectly return true. To accomodate it, add another isatty() check for the standard output stream as well. Reported-by: Erik Faye-Lund <kusmabite@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-02-22push: add '--prune' optionLibravatar Felipe Contreras1-0/+2
When pushing groups of refs to a remote, there is no simple way to remove old refs that still exist at the remote that is no longer updated from us. This will allow us to remove such refs from the remote. With this change, running this command $ git push --prune remote refs/heads/*:refs/remotes/laptop/* removes refs/remotes/laptop/foo from the remote if we do not have branch "foo" locally anymore.

2012-02-17config: add include directiveLibravatar Jeff King1-10/+28
It can be useful to split your ~/.gitconfig across multiple files. For example, you might have a "main" file which is used on many machines, but a small set of per-machine tweaks. Or you may want to make some of your config public (e.g., clever aliases) while keeping other data back (e.g., your name or other identifying information). Or you may want to include a number of config options in some subset of your repos without copying and pasting (e.g., you want to reference them from the .git/config of participating repos). This patch introduces an include directive for config files. It looks like: [include] path = /path/to/file This is syntactically backwards-compatible with existing git config parsers (i.e., they will see it as another config entry and ignore it unless you are looking up include.path). The implementation provides a "git_config_include" callback which wraps regular config callbacks. Callers can pass it to git_config_from_file, and it will transparently follow any include directives, passing all of the discovered options to the real callback. Include directives are turned on automatically for "regular" git config parsing. This includes calls to git_config, as well as calls to the "git config" program that do not specify a single file (e.g., using "-f", "--global", etc). They are not turned on in other cases, including: 1. Parsing of other config-like files, like .gitmodules. There isn't a real need, and I'd rather be conservative and avoid unnecessary incompatibility or confusion. 2. Reading single files via "git config". This is for two reasons: a. backwards compatibility with scripts looking at config-like files. b. inspection of a specific file probably means you care about just what's in that file, not a general lookup for "do we have this value anywhere at all". If that is not the case, the caller can always specify "--includes". 3. Writing files via "git config"; we want to treat include.* variables as literal items to be copied (or modified), and not expand them. So "git config --unset-all foo.bar" would operate _only_ on .git/config, not any of its included files (just as it also does not operate on ~/.gitconfig).

2012-02-17config: stop using config_exclusive_filenameLibravatar Jeff King1-24/+35
The git-config command sometimes operates on the default set of config files (either reading from all, or writing to repo config), and sometimes operates on a specific file. In the latter case, we set the magic global config_exclusive_filename, and the code in config.c does the right thing. Instead, let's have git-config use the "advanced" variants of config.c's functions which let it specify an individual filename (or NULL for the default). This makes the code a lot more obvious, and fixes two small bugs: 1. A relative path specified by GIT_CONFIG=foo will look in the wrong directory if we have to chdir as part of repository setup. We already handle this properly for "git config -f foo", but the GIT_CONFIG lookup used config_exclusive_filename directly. By dropping to a single magic variable, the GIT_CONFIG case now just works. 2. Calling "git config -f foo --edit" would not respect core.editor. This is because just before editing, we called git_config, which would respect the config_exclusive_filename setting, even though this particular git_config call was not about looking in the user's specified file, but rather about loading actual git config, just as any other git program would.

2012-02-17config: copy the return value of prefix_filenameLibravatar Jeff King1-3/+4
The prefix_filename function returns a pointer to a static buffer which may be overwritten by subsequent calls. Since we are going to keep the result around for a while, let's be sure to duplicate it for safety. I don't think this can be triggered as a bug in the current code, but it's a good idea to be defensive, as any resulting bug would be quite subtle.

2012-02-13do not override receive-pack errorsLibravatar Clemens Buchacher1-7/+17
Receive runs rev-list --verify-objects in order to detect missing objects. However, such errors are ignored and overridden later. Instead, consequently ignore all update commands for which an error has already been detected. Some tests in t5504 are obsoleted by this change, because invalid objects are detected even if fsck is not enabled. Instead, they now test for different error messages depending on whether or not fsck is turned on. A better fix would be to force a corruption that will be detected by fsck but not by rev-list.

2012-02-08tag: do not show non-tag contents with "-n"Libravatar Junio C Hamano1-10/+12
"git tag -n" did not check the type of the object it is reading the top n lines from. At least, avoid showing the beginning of trees and blobs when dealing with lightweight tags that point at them. As the payload of a tag and a commit look similar in that they both start with a header block, which is skipped for the purpose of "-n" output, followed by human readable text, allow the message of commit objects to be shown just like the contents of tag objects. This avoids regression for people who have been using "tag -n" to show the log messages of commits that are pointed at by lightweight tags. Test script is from Jeff King.

2012-02-07drop odd return value semantics from userdiff_configLibravatar Jeff King3-19/+4
When the userdiff_config function was introduced in be58e70 (diff: unify external diff and funcname parsing code, 2008-10-05), it used a return value convention unlike any other config callback. Like other callbacks, it used "-1" to signal error. But it returned "1" to indicate that it found something, and "0" otherwise; other callbacks simply returned "0" to indicate that no error occurred. This distinction was necessary at the time, because the userdiff namespace overlapped slightly with the color configuration namespace. So "diff.color.foo" could mean "the 'foo' slot of diff coloring" or "the 'foo' component of the "color" userdiff driver". Because the color-parsing code would die on an unknown color slot, we needed the userdiff code to indicate that it had matched the variable, letting us bypass the color-parsing code entirely. Later, in 8b8e862 (ignore unknown color configuration, 2009-12-12), the color-parsing code learned to silently ignore unknown slots. This means we no longer need to protect userdiff-matched variables from reaching the color-parsing code. We can therefore change the userdiff_config calling convention to a more normal one. This drops some code from each caller, which is nice. But more importantly, it reduces the cognitive load for readers who may wonder why userdiff_config is unlike every other config callback. There's no need to add a new test confirming that this works; t4020 already contains a test that sets diff.color.external.
