2012-06-22diff-no-index: exit(1) if 'diff --quiet <repo file> <external file>' finds ↵Libravatar Tim Henigan1-1/+72
changes When running 'git diff --quiet <file1> <file2>', if file1 or file2 is outside the repository, it will exit(0) even if the files differ. It should exit(1) when they differ. This happens because 'diff_no_index' looks at the 'found_changes' member from 'diff_options' to determine if changes were made. This is the wrong thing to do, since it is only set if xdiff is actually run and it finds a change (the diff machinery will optimize out the xdiff call when it is not necessary) and in that case HAS_CHANGED flag needs to be taken into account. Use diff_result_code() that knows all these details for the correct exit value instead. Signed-off-by: Tim Henigan <tim.henigan@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2012-06-19completion: respect $GIT_DIRLibravatar SZEDER Gábor1-1/+9
The __gitdir() helper function finds out the path of the git repository by running 'git rev-parse --git-dir'. However, it has a shortcut first to avoid the overhead of running a git command in a subshell when the current directory is at the top of the work tree, i.e. when it contains a '.git' subdirectory. If the 'GIT_DIR' environment variable is set then it specifies the path to the git repository, and the autodetection of the '.git' directory is not necessary. However, $GIT_DIR is only taken into acocunt by 'git rev-parse --git-dir', and the check for the '.git' subdirectory is performed first, so it wins over the path given in $GIT_DIR. There are several completion (helper) functions that depend on __gitdir(), and when the above case triggers the completion script will do weird things, like offering refs, aliases, or stashes from a different repository, or displaying wrong or broken prompt, etc. So check first whether $GIT_DIR is set, and only proceed with checking the '.git' directory in the current directory if it isn't. 'git rev-parse' would also check whether the path in $GIT_DIR is a proper '.git' directory, i.e. 'HEAD', 'refs/', and 'objects/' are present and accessible, but we don't have to be that thorough for the bash prompt. And we've lived with an equally permissive check for '.git' in the current working directory for years anyway.

2012-06-19remove the impression of unexpectedness when access is deniedLibravatar Heiko Voigt1-9/+7
If a server accessed through ssh is denying access git will currently issue the message "fatal: The remote end hung up unexpectedly" as the last line. This sounds as if something really ugly just happened. Since this is a quite typical situation in which users regularly get we do not say that if it happens at the beginning when reading the remote heads. If its in the very first beginning of reading the remote heads it is very likely an authentication error or a missing repository. If it happens later during reading the remote heads we still indicate that it happened during this initial contact phase.

2012-06-18verify_filename(): ask the caller to chose the kind of diagnosisLibravatar Matthieu Moy1-1/+1
verify_filename() can be called in two different contexts. Either we just tried to interpret a string as an object name, and it fails, so we try looking for a working tree file (i.e. we finished looking at revs that come earlier on the command line, and the next argument must be a pathname), or we _know_ that we are looking for a pathname, and shouldn't even try interpreting the string as an object name. For example, with this change, we get: $ git log COPYING HEAD:inexistant fatal: HEAD:inexistant: no such path in the working tree. Use '-- <path>...' to specify paths that do not exist locally. $ git log HEAD:inexistant fatal: Path 'inexistant' does not exist in 'HEAD' Signed-off-by: Matthieu Moy <Matthieu.Moy@imag.fr> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-06-18sha1_name: do not trigger detailed diagnosis for file argumentsLibravatar Matthieu Moy1-0/+11
diagnose_invalid_sha1_path() is meant to be called to diagnose a misspelt <treeish>:<pathname> when <pathname> does not exist in <treeish>. However, the code may call it if <treeish>:<pathname> is invalid (which triggers another call with only_to_die == 1), but for another reason. This happens when calling e.g. git log existing-file HEAD:existing-file because existing-file is a path and not a revision, the code verifies that the arguments that follow to be paths. This leads to an incorrect message like "existing-file does not exist in HEAD", even though the path exists in HEAD. Check that the search for <pathname> in <treeish> fails before triggering the diagnosis. Signed-off-by: Matthieu Moy <Matthieu.Moy@imag.fr> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2012-06-14t7400: avoid path mangling issuesLibravatar Johannes Sixt1-3/+8
A recently introduced test uses an absolute path. But when run on Windows using the MSYS bash, such a path is mangled into a Windows style path when it is passed to 'git config'. The subsequent 'test' then compares the mangled path to the unmangled version and reports a failure. A path beginning with two slashes denotes a network directory (//server/share path) and is not mangled. Use that trick to side-step the issue. Just in case that 'git submodule init' regresses in such a way that it accesses the URL, use a path name that is unlikely to exist on POSIX systems, and that cannot be a server name on Windows.

This patch provides new informative help messages in the display of 'git status' (at the top) during conflicts, rebase, am, bisect or cherry-pick process. The new messages are not shown when using options such as -s or --porcelain. The messages about the current situation of the user are always displayed but the advices on what the user needs to do in order to resume a rebase/bisect/am/commit after resolving conflicts can be hidden by setting advice.statushints to 'false' in the config file.

2012-06-13rebase -i: teach "--exec <cmd>"Libravatar Lucien Kong1-0/+117
During an interactive rebase session, it is sometimes desirable to run tests on each commit in the resulting history. This can be done by adding "exec <test command>" when editing the insn sheet, but the command used for testing is often the same for all resulting commits. By passing "--exec <cmd>" from the command line, automatically add these "exec" lines after each commit in the final history. To work well with the --autosquash option, these are added at the end of each run of "fixup" and "squash".

Commit 7f02f3d7 (completion: rename internal helpers _git and _gitk, 2012-05-19) renamed said functions to _main_git() and _main_gitk(), respectively. By convention the name of our git-completion-specific functions start with '_git' or '__git' prefix, so rename those functions once again to put them back into our "namespace".

2012-06-07t1304: improve setfacl prerequisite setupLibravatar Jeff King1-10/+9
t1304 first runs setfacl as an experiment to see whether the filesystem supports ACLs, and skips the remaining tests if it does not. However, our setfacl run did not exercise the ACLs very well, and some filesystems may support our initial setfacl, but not the rest of the test. In particular, some versions of ecryptfs will erroneously apply the umask on top of an inherited directory ACL, causing our tests to fail. Let's be more careful and make sure both that we can read back the user ACL we set, and that the inherited ACL is propagated correctly. The latter catches the ecryptfs bug, but may also catch other bugs (e.g., an implementation which does not handle inherited ACLs at all). Since we're making the setup more complex, let's move it into its own test. This will hide the output for us unless the user wants to run "-v" to see it (and we don't need to bother printing anything about setfacl failing; the remaining tests will properly print "skip" due to the missing prerequisite).

2012-06-06submodule: fix sync handling of some relative superproject origin URLsLibravatar Jon Seymour1-4/+4
When the origin URL of the superproject is itself relative, git submodule sync configures the remote.origin.url configuration property of the submodule with a path that is relative to the work tree of the superproject rather than the work tree of the submodule. To fix this an 'up_path' that navigates from the work tree of the submodule to the work tree of the superproject needs to be prepended to the URL otherwise calculated. Correct handling of superproject origin URLs like foo, ./foo and ./foo/bar is left to a subsequent patch since an additional change is required to handle these cases. The documentation of resolve_relative_url() is expanded to give a more thorough description of the function's objective.
