"git grep" by default does not fall back to its "--no-index" behaviour outside a directory under Git's control (otherwise the user may by mistake end up running a huge recursive search); with a new configuration (set in $HOME/.gitconfig--by definition this cannot be set in the config file per project), this safety can be disabled. * tg/grep-no-index-fallback: builtin/grep: add grep.fallbackToNoIndex config t7810: correct --no-index test

d95138e6 (setup: set env $GIT_WORK_TREE when work tree is set, like $GIT_DIR, 2015-06-26) attempted to work around a glitch in alias handling by overwriting GIT_WORK_TREE environment variable to affect subprocesses when set_git_work_tree() gets called, which resulted in a rather unpleasant regression to "clone" and "init".

Some "git notes" operations, e.g. "git log --notes=<note>", should be able to read notes from any tree-ish that is shaped like a notes tree, but the notes infrastructure required that the argument must be a ref under refs/notes/.

2016-01-12notes: allow treeish expressions as notes refLibravatar Mike Hommey1-0/+10
init_notes() is the main point of entry to the notes API. It ensures that the input can be used as ref, because it needs a ref to update to store notes tree after modifying it. There however are many use cases where notes tree is only read, e.g. "git log --notes=...". Any notes-shaped treeish could be used for such purpose, but it is not allowed due to existing restriction. Allow treeish expressions to be used in the case the notes tree is going to be used without write "permissions". Add a flag to distinguish whether the notes tree is intended to be used read-only, or will be updated. With this change, operations that use notes read-only can be fed any notes-shaped tree-ish can be used, e.g. git log --notes=notes@{1}.

Currently when git grep is used outside of a git repository without the --no-index option git simply dies. For convenience, add a grep.fallbackToNoIndex configuration variable.

2016-01-11t7810: correct --no-index testLibravatar Thomas Gummerer1-4/+4
GIT_CEILING_DIRECTORIES doesn't prevent chdir up into another directory while looking for a repository directory if it is equal to the current directory. Because of this, the test which claims to test the git grep --no-index command outside of a repository actually tests it inside of a repository. The test_must_fail assertions still pass because the git grep only looks at untracked files and therefore no file matches, but not because it's run outside of a repository as it was originally intended. Set the GIT_CEILING_DIRECTORIES environment variable to the parent directory of the directory in which the git grep command is executed, to make sure it is actually run outside of a git repository. In addition, the && chain was broken in a couple of places in the same test, fix that. Signed-off-by: Thomas Gummerer <t.gummerer@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

This reverts commit 57534ee77d22e725d971ee89c77dc6aad61c573f. The feature added in that commit requires that patterns behave the same way from anywhere. But some patterns can behave differently depending on current "working" directory. The conditions to catch and avoid these patterns are too loose. The untracked listing[1] and sparse-checkout selection[2] can become incorrect as a result.

2016-01-05reflog-walk: don't segfault on non-commit sha1's in the reflogLibravatar Dennis Kaarsemaker1-0/+13
git reflog (ab)uses the log machinery to display its list of log entries. To do so it must fake commit parent information for the log walker. For refs in refs/heads this is no problem, as they should only ever point to commits. Tags and other refs however can point to anything, thus their reflog may contain non-commit objects. To avoid segfaulting, we check whether reflog entries are commits before feeding them to the log walker and skip any non-commits. This means that git reflog output will be incomplete for such refs, but that's one step up from segfaulting. A more complete solution would be to decouple git reflog from the log walker machinery.

2016-01-05t6050-replace: make failing editor test more robustLibravatar SZEDER Gábor1-3/+7
'git replace --edit' should error out when the invoked editor fails, but the test checking this behavior would not notice if this weren't the case. The test in question, ever since it was added in 85f98fc037ae (replace: add tests for --edit, 2014-05-17), has simulated a failing editor in an unconventional way: test_must_fail env GIT_EDITOR='./fakeeditor;false' git replace --edit I presume the reason for this unconventional editor was the fact that 'git replace --edit' requires the edited object to be different from the original, but a mere 'false' as editor would leave the object unchanged and 'git replace --edit' would error out anyway complaining about the new and the original object files being the same. Running 'fakeeditor' before 'false' was supposed to ensure that the object file is modified and thus 'git replace --edit' errors out because of the failed editor. However, this editor doesn't actually modify the edited object, because start_command() turns this editor into: /bin/sh -c './fakeeditor;false "$@"' './fakeeditor;false' \ '.../.git/REPLACE_EDITOBJ' This means that the test's fakeeditor script doesn't even get the path of the object to be edited as argument, triggering error messages from the commands executed inside the script ('sed' and 'mv'), and ultimately leaving the object file unchanged. If a patch were to remove the die() from the error path after launch_editor(), the test would not catch it, because 'git replace' would continue execution past launch_editor() and would error out a bit later due to the unchanged edited object. Though 'git replace' would error out for the wrong reason, this would satisfy 'test_must_fail' just as well, and the test would succeed leaving the undesired change unnoticed. Create a proper failing fake editor script for this test to ensure that the edited object is in fact modified and 'git replace --edit' won't error out because the new and original object files are the same.

2015-12-22git.c: make sure we do not leak GIT_* to alias scriptsLibravatar Nguyễn Thái Ngọc Duy1-0/+17
The unfortunate commit d95138e (setup: set env $GIT_WORK_TREE when work tree is set, like $GIT_DIR - 2015-06-26) exposes another problem, besides git-clone that's described in the previous commit. If GIT_WORK_TREE (or even GIT_DIR) is exported to an alias script, it may mislead git commands in the script where the repo is. Granted, most scripts work on the repo where the alias is summoned from. But nowhere do we forbid the script to visit another repository. The revert of d95138e in the previous commit is sufficient as a fix. However, to protect us from accidentally leaking GIT_* environment variables again, we restore certain sensitive env before calling the external script. GIT_PREFIX is let through because there's another setup side effect that we simply accepted so far: current working directory is moved. Maybe in future we can introduce a new alias format that guarantees no cwd move, then we can unexport GIT_PREFIX.

2015-12-22setup.c: re-fix d95138e (setup: set env $GIT_WORK_TREE when ..Libravatar Nguyễn Thái Ngọc Duy2-1/+24
Commit d95138e [1] attempted to fix a .git file problem by setting GIT_WORK_TREE whenever GIT_DIR is set. It sounded harmless because we handle GIT_DIR and GIT_WORK_TREE side by side for most commands, with two exceptions: git-init and git-clone. "git clone" is not happy with d95138e. This command ignores GIT_DIR but respects GIT_WORK_TREE [2] [3] which means it used to run fine from a hook, where GIT_DIR was set but GIT_WORK_TREE was not (*). With d95138e, GIT_WORK_TREE is set all the time and git-clone interprets that as "I give you order to put the worktree here", usually against the user's intention. The solution in d95138e is reverted earlier, and instead we reuse the solution from c056261 [4]. It fixed another setup-messed- up-by-alias by saving and restoring env and spawning a new process, but for git-clone and git-init only. Now we conclude that setup-messed-up-by-alias is always evil. So the env restoration is done for _all_ commands, including external ones, whenever aliases are involved. It fixes what d95138e tried to fix, without upsetting git-clone-inside-hooks. The test from d95138e remains to verify it's not broken by this. A new test is added to make sure git-clone-inside-hooks remains happy. (*) GIT_WORK_TREE was not set _most of the time_. In some cases GIT_WORK_TREE is set and git-clone will behave differently. The use of GIT_WORK_TREE to direct git-clone to put work tree elsewhere looks like a mistake because it causes surprises this way. But that's a separate story.

2015-12-17revision.c: propagate tag names from pending arrayLibravatar Jeff King1-0/+29
When we unwrap a tag to find its commit for a traversal, we do not propagate the "name" field of the tag in the pending array (i.e., the ref name the user gave us in the first place) to the commit (instead, we use an empty string). This means that "git log --source" will never show the tag-name for commits we reach through it. This was broken in 2073949 (traverse_commit_list: support pending blobs/trees with paths, 2014-10-15). That commit tried to be careful and avoid propagating the path information for a tag (which would be nonsensical) to trees and blobs. But it should not have cut off the "name" field, which should carry forward to children. Note that this does mean that the "name" field will carry forward to blobs and trees, too. Whereas prior to 2073949, we always gave them an empty string. This is the right thing to do, but in practice no callers probably use it (since now we have an explicit separate "path" field, which was the point of 2073949). We add tests here not only for the broken case, but also a basic sanity test of "log --source" in general, which did not have any coverage in the test suite.

2015-12-16run-command: add an asynchronous parallel child processorLibravatar Stefan Beller1-0/+53
This allows to run external commands in parallel with ordered output on stderr. If we run external commands in parallel we cannot pipe the output directly to the our stdout/err as it would mix up. So each process's output will flow through a pipe, which we buffer. One subprocess can be directly piped to out stdout/err for a low latency feedback to the user. Example: Let's assume we have 5 submodules A,B,C,D,E and each fetch takes a different amount of time as the different submodules vary in size, then the output of fetches in sequential order might look like this: time --> output: |---A---| |-B-| |-------C-------| |-D-| |-E-| When we schedule these submodules into maximal two parallel processes, a schedule and sample output over time may look like this: process 1: |---A---| |-D-| |-E-| process 2: |-B-| |-------C-------| output: |---A---|B|---C-------|DE So A will be perceived as it would run normally in the single child version. As B has finished by the time A is done, we can dump its whole progress buffer on stderr, such that it looks like it finished in no time. Once that is done, C is determined to be the visible child and its progress will be reported in real time. So this way of output is really good for human consumption, as it only changes the timing, not the actual output. For machine consumption the output needs to be prepared in the tasks, by either having a prefix per line or per block to indicate whose tasks output is displayed, because the output order may not follow the original sequential ordering: |----A----| |--B--| |-C-| will be scheduled to be all parallel: process 1: |----A----| process 2: |--B--| process 3: |-C-| output: |----A----|CB This happens because C finished before B did, so it will be queued for output before B. To detect when a child has finished executing, we check interleaved with other actions (such as checking the liveliness of children or starting new processes) whether the stderr pipe still exists. Once a child closed its stderr stream, we assume it is terminating very soon, and use `finish_command()` from the single external process execution interface to collect the exit status. By maintaining the strong assumption of stderr being open until the very end of a child process, we can avoid other hassle such as an implementation using `waitpid(-1)`, which is not implemented in Windows.

2015-12-11rebase -i: remember merge options beyond continue actionsLibravatar Fabian Ruch1-0/+16
If the user explicitly specified a merge strategy or strategy options, continue to use that strategy/option after "rebase --continue". Add a test of the corrected behavior. If --merge is specified or implied by -s or -X, then "strategy and "strategy_opts" are set to values from which "strategy_args" can be derived; otherwise they are set to empty strings. Either way, their values are propagated from one step of an interactive rebase to the next via state files. "do_merge", on the other hand, is *not* propagated to later steps of an interactive rebase. Therefore, making the initialization of "strategy_args" conditional on "do_merge" being set prevents later steps of an interactive rebase from setting it correctly. Luckily, we don't need the "do_merge" guard at all. If the rebase was started without --merge, then "strategy" and "strategy_opts" are both the empty string, which results in "strategy_args" also being set to the empty string, which is just what we want in that situation. So remove the "do_merge" guard and derive "strategy_args" from "strategy" and "strategy_opts" every time.

Add a mechanism to allow 'bash' to catch such uses, and fix the ones that were found. * jk/test-lint-forbid-when-finished-in-subshell: test-lib-functions: detect test_when_finished in subshell t7800: don't use test_config in a subshell test-lib-functions: support "test_config -C <dir> ..." t5801: don't use test_when_finished in a subshell t7610: don't use test_config in a subshell

2015-12-10git-p4: add option to keep empty commitsLibravatar Lars Schneider1-0/+134
A changelist that contains only excluded files due to a client spec was imported as an empty commit. Fix that issue by ignoring these commits. Add option "git-p4.keepEmptyCommits" to make the previous behavior available.

2015-12-08Merge branch 'ls/test-must-fail-sigpipe'Libravatar Junio C Hamano3-20/+41
Fix some racy client/server tests by treating SIGPIPE the same as a normal non-zero exit. * ls/test-must-fail-sigpipe: add "ok=sigpipe" to test_must_fail and use it to fix flaky tests implement test_might_fail using a refactored test_must_fail

Produce correct "dirty" marker for shell prompts, even when we are on an orphan or an unborn branch. * sg/bash-prompt-dirty-orphan: bash prompt: indicate dirty index even on orphan branches bash prompt: remove a redundant 'git diff' option bash prompt: test dirty index and worktree while on an orphan branch
2015-12-08Merge branch 'jk/rebase-no-autostash' into maintLibravatar Junio C Hamano1-0/+10
There was no way to defeat a configured rebase.autostash variable from the command line, as "git rebase --no-autostash" was missing. * jk/rebase-no-autostash: Documentation/git-rebase: fix --no-autostash formatting rebase: support --no-autostash
2015-12-04t3404: fix quoting of redirect for some versions of bashLibravatar Charles Bailey1-1/+1
As CodingGuidelines says, some versions of bash errors out when $variable substitution is used as the target for redirection without being quoted (even though POSIX may not require such a quote).

2015-12-04push: follow the "last one wins" convention for --recurse-submodulesLibravatar Mike Crowe1-0/+41
Use the "last one wins" convention for --recurse-submodules rather than treating conflicting options as an error. Also, fix the declaration of the file-scope recurse_submodules global variable to put it on a separate line.

2015-12-04push: test that --recurse-submodules on command line overrides configLibravatar Mike Crowe1-4/+28
t5531 only checked that the push.recurseSubmodules config option was overridden by passing --recurse-submodules=check on the command line. Add new tests for overriding with --recurse-submodules=no, --no-recurse-submodules and --recurse-submodules=push too. Also correct minor typo in test commit message.

2015-12-04Merge branch 'da/difftool' into maintLibravatar Junio C Hamano1-0/+19
The code to prepare the working tree side of temporary directory for the "dir-diff" feature forgot that symbolic links need not be copied (or symlinked) to the temporary area, as the code already special cases and overwrites them. Besides, it was wrong to try computing the object name of the target of symbolic link, which may not even exist or may be a directory. * da/difftool: difftool: ignore symbolic links in use_wt_file
