"git clone --resurse-submodules --reference $path $URL" is a way to reduce network transfer cost by borrowing objects in an existing $path repository when cloning the superproject from $URL; it learned to also peek into $path for presense of corresponding repositories of submodules and borrow objects from there when able. * sb/submodule-clone-rr: clone: recursive and reference option triggers submodule alternates clone: implement optional references clone: clarify option_reference as required clone: factor out checking for an alternate path submodule--helper update-clone: allow multiple references submodule--helper module-clone: allow multiple references t7408: merge short tests, factor out testing method t7408: modernize style

2016-08-31allow do_submodule_path to work even if submodule isn't checked outLibravatar Jacob Keller1-0/+127
Currently, do_submodule_path will attempt locating the .git directory by using read_gitfile on <path>/.git. If this fails it just assumes the <path>/.git is actually a git directory. This is good because it allows for handling submodules which were cloned in a regular manner first before being added to the superproject. Unfortunately this fails if the <path> is not actually checked out any longer, such as by removing the directory. Fix this by checking if the directory we found is actually a gitdir. In the case it is not, attempt to lookup the submodule configuration and find the name of where it is stored in the .git/modules/ directory of the superproject. If we can't locate the submodule configuration, this might occur because for example a submodule gitlink was added but the corresponding .gitmodules file was not properly updated. A die() here would not be pleasant to the users of submodule diff formats, so instead, modify do_submodule_path() to return an error code: - git_pathdup_submodule() returns NULL when we fail to find a path. - strbuf_git_path_submodule() propagates the error code to the caller. Modify the callers of these functions to check the error code and fail properly. This ensures we don't attempt to use a bad path that doesn't match the corresponding submodule. Because this change fixes add_submodule_odb() to work even if the submodule is not checked out, update the wording of the submodule log diff format to correctly display that the submodule is "not initialized" instead of "not checked out" Add tests to ensure this change works as expected.

2016-08-31graph: add support for --line-prefix on all graph-aware outputLibravatar Jacob Keller4-0/+373
Add an extension to git-diff and git-log (and any other graph-aware displayable output) such that "--line-prefix=<string>" will print the additional line-prefix on every line of output. To make this work, we have to fix a few bugs in the graph API that force graph_show_commit_msg to be used only when you have a valid graph. Additionally, we extend the default_diff_output_prefix handler to work even when no graph is enabled. This is somewhat of a hack on top of the graph API, but I think it should be acceptable here. This will be used by a future extension of submodule display which displays the submodule diff as the actual diff between the pre and post commit in the submodule project. Add some tests for both git-log and git-diff to ensure that the prefix is honored correctly. Signed-off-by: Jacob Keller <jacob.keller@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2016-08-29blame: fix segfault on untracked filesLibravatar Thomas Gummerer1-0/+5
Since 3b75ee9 ("blame: allow to blame paths freshly added to the index", 2016-07-16) git blame also looks at the index to determine if there is a file that was freshly added to the index. cache_name_pos returns -pos - 1 in case there is no match is found, or if the name matches, but the entry has a stage other than 0. As git blame should work for unmerged files, it uses strcmp to determine whether the name of the returned position matches, in which case the file exists, but is merely unmerged, or if the file actually doesn't exist in the index. If the repository is empty, or if the file would lexicographically be sorted as the last file in the repository, -cache_name_pos - 1 is outside of the length of the active_cache array, causing git blame to segfault. Guard against that, and die() normally to restore the old behaviour.

2016-08-25Merge branch 'bw/mingw-avoid-inheriting-fd-to-lockfile'Libravatar Junio C Hamano1-0/+13
The tempfile (hence its user lockfile) API lets the caller to open a file descriptor to a temporary file, write into it and then finalize it by first closing the filehandle and then either removing or renaming the temporary file. When the process spawns a subprocess after obtaining the file descriptor, and if the subprocess has not exited when the attempt to remove or rename is made, the last step fails on Windows, because the subprocess has the file descriptor still open. Open tempfile with O_CLOEXEC flag to avoid this (on Windows, this is mapped to O_NOINHERIT). * bw/mingw-avoid-inheriting-fd-to-lockfile: mingw: ensure temporary file handles are not inherited by child processes t6026-merge-attr: child processes must not inherit index.lock handles

2016-08-23mingw: ensure temporary file handles are not inherited by child processesLibravatar Ben Wijen1-1/+1
When the index is locked and child processes inherit the handle to said lock and the parent process wants to remove the lock before the child process exits, on Windows there is a problem: it won't work because files cannot be deleted if a process holds a handle on them. The symptom: Rename from 'xxx/.git/index.lock' to 'xxx/.git/index' failed. Should I try again? (y/n) Spawning child processes with bInheritHandles==FALSE would not work because no file handles would be inherited, not even the hStdXxx handles in STARTUPINFO (stdin/stdout/stderr). Opening every file with O_NOINHERIT does not work, either, as e.g. git-upload-pack expects inherited file handles. This leaves us with the only way out: creating temp files with the O_NOINHERIT flag. This flag is Windows-specific, however. For our purposes, it is equivalent to O_CLOEXEC (which does not exist on Windows), so let's just open temporary files with the O_CLOEXEC flag and map that flag to O_NOINHERIT on Windows. As Eric Wong pointed out, we need to be careful to handle the case where the Linux headers used to compile Git support O_CLOEXEC but the Linux kernel used to run Git does not: it returns an EINVAL. This fixes the test that we just introduced to demonstrate the problem.

2016-08-18t6026-merge-attr: child processes must not inherit index.lock handlesLibravatar Ben Wijen1-0/+13
On Windows, a file cannot be removed unless all file handles to it have been released. Hence it is particularly important to close handles when spawning children (which would probably not even know that they hold on to those handles). The example chosen for this test is a custom merge driver that indeed has no idea that it blocks the deletion of index.lock. The full use case is a daemon that lives on after the merge, with subsequent invocations handing off to the daemon, thereby avoiding hefty start-up costs. We simulate this behavior by simply sleeping one second. Note that the test only fails on Windows, due to the file locking issue. Since we have no way to say "expect failure with MINGW, success otherwise", we simply skip this test on Windows for now.

2016-08-17clone: recursive and reference option triggers submodule alternatesLibravatar Stefan Beller1-0/+43
When `--recursive` and `--reference` is given, it is reasonable to expect that the submodules are created with references to the submodules of the given alternate for the superproject. An initial attempt to do this was presented to the mailing list, which used flags that are passed around ("--super-reference") that instructed the submodule clone to look for a reference in the submodules of the referenced superproject. This is not well thought out, as any further `submodule update` should also respect the initial setup. When a new submodule is added to the superproject and the alternate of the superproject does not know about that submodule yet, we rather error out informing the user instead of being unclear if we did or did not use a submodules alternate. To solve this problem introduce new options that store the configuration for what the user wanted originally.

2016-08-16rev-parse: respect core.hooksPath in --git-pathLibravatar Johannes Schindelin1-0/+6
The idea of the --git-path option is not only to avoid having to prefix paths with the output of --git-dir all the time, but also to respect overrides for specific common paths inside the .git directory (e.g. `git rev-parse --git-path objects` will report the value of the environment variable GIT_OBJECT_DIRECTORY, if set). When introducing the core.hooksPath setting, we forgot to adjust git_path() accordingly. This patch fixes that. While at it, revert the special-casing of core.hooksPath in run-command.c, as it is now no longer needed.

2016-08-16t/Makefile: ensure that paths are valid on platforms we careLibravatar Johannes Schindelin1-1/+10
Some pathnames that are okay on ext4 and on HFS+ cannot be checked out on Windows. Tests that want to see operations on such paths on filesystems that support them must do so behind appropriate test prerequisites, and must not include them in the source tree (instead they should create them when they run). Otherwise, the source tree cannot even be checked out. Make sure that double-quotes, asterisk, colon, greater/less-than, question-mark, backslash, tab, vertical-bar, as well as any non-ASCII characters never appear in the pathnames with a new test-lint-* target as part of a `make test`. To that end, we call `git ls-files` (ensuring that the paths are quoted properly), relying on the fact that paths containing non-ASCII characters are quoted within double-quotes. In case that the source code does not actually live in a Git repository (e.g. when extracted from a .zip file), or that the `git` executable cannot be executed, we simply ignore the error for now; In that case, our trusty Continuous Integration will be the last line of defense and catch any problematic file name. Noticed when a topic wanted to add a pathname with '>' in it. A check like this will prevent a similar problems from happening in the future.

2016-08-15difftool: always honor fatal error exit codesLibravatar John Keeping1-0/+6
At the moment difftool's "trust exit code" logic always suppresses the exit status of the diff utility we invoke. This is useful because we don't want to exit just because diff returned "1" because the files differ, but it's confusing if the shell returns an error because the selected diff utility is not found. POSIX specifies 127 as the exit status for "command not found", 126 for "command found but is not executable" and values greater than 128 if the command terminated because it received a signal [1] and at least bash and dash follow this specification, while diff utilities generally use "1" for the exit status we want to ignore. Handle any value of 126 or greater as a special value indicating that some form of fatal error occurred.

2016-08-14convert: Correct NNO tests and missing `LF will be replaced by CRLF`Libravatar Torsten Bögershausen1-3/+3
When a non-reversible CRLF conversion is done in "git add", a warning is printed on stderr (or Git dies, depending on checksafe) The function commit_chk_wrnNNO() in t0027 was written to test this, but did the wrong thing: Instead of looking at the warning from "git add", it looked at the warning from "git commit". This is racy because "git commit" may not have to do CRLF conversion at all if it can use the sha1 value from the index (which depends on whether "add" and "commit" run in a single second). Correct t0027 and replace the commit for each and every file with a commit of all files in one go. The function commit_chk_wrnNNO() should be renamed in a separate commit. Now that t0027 does the right thing, it detects a bug in covert.c: This sequence should generate the warning `LF will be replaced by CRLF`, but does not: $ git init $ git config core.autocrlf false $ printf "Line\r\n" >file $ git add file $ git commit -m "commit with CRLF" $ git config core.autocrlf true $ printf "Line\n" >file $ git add file "git add" calls crlf_to_git() in convert.c, which calls check_safe_crlf(). When has_cr_in_index(path) is true, crlf_to_git() returns too early and check_safe_crlf() is not called at all. Factor out the code which determines if "git checkout" converts LF->CRLF into will_convert_lf_to_crlf(). Update the logic around check_safe_crlf() and "simulate" the possible LF->CRLF conversion at "git checkout" with help of will_convert_lf_to_crlf().

"git difftool <paths>..." started in a subdirectory failed to interpret the paths relative to that directory, which has been fixed. * jk/difftool-in-subdir: difftool: use Git::* functions instead of passing around state difftool: avoid $GIT_DIR and $GIT_WORK_TREE difftool: fix argument handling in subdirs
2016-08-11rebase: avoid computing unnecessary patch IDsLibravatar Kevin Willford2-0/+57
The `rebase` family of Git commands avoid applying patches that were already integrated upstream. They do that by using the revision walking option that computes the patch IDs of the two sides of the rebase (local-only patches vs upstream-only ones) and skipping those local patches whose patch ID matches one of the upstream ones. In many cases, this causes unnecessary churn, as already the set of paths touched by a given commit would suffice to determine that an upstream patch has no local equivalent. This hurts performance in particular when there are a lot of upstream patches, and/or large ones. Therefore, let's introduce the concept of a "diff-header-only" patch ID, compare those first, and only evaluate the "full" patch ID lazily. Please note that in contrast to the "full" patch IDs, those "diff-header-only" patch IDs are prone to collide with one another, as adjacent commits frequently touch the very same files. Hence we now have to be careful to allow multiple hash entries with the same hash. We accomplish that by using the hashmap_add() function that does not even test for hash collisions. This also allows us to evaluate the full patch ID lazily, i.e. only when we found commits with matching diff-header-only patch IDs. We add a performance test that demonstrates ~1-6% improvement. In practice this will depend on various factors such as how many upstream changes and how big those changes are along with whether file system caches are cold or warm. As Git's test suite has no way of catching performance regressions, we also add a regression test that verifies that the full patch ID computation is skipped when the diff-header-only computation suffices.
