2016-02-05Merge branch 'nd/stop-setenv-work-tree' into maintLibravatar Junio C Hamano1-1/+1
An earlier change in 2.5.x-era broke users' hooks and aliases by exporting GIT_WORK_TREE to point at the root of the working tree, interfering when they tried to use a different working tree without setting GIT_WORK_TREE environment themselves. * nd/stop-setenv-work-tree: Revert "setup: set env $GIT_WORK_TREE when work tree is set, like $GIT_DIR"
2015-12-22Revert "setup: set env $GIT_WORK_TREE when work tree is set, like $GIT_DIR"Libravatar Nguyễn Thái Ngọc Duy1-1/+1
This reverts d95138e6 (setup: set env $GIT_WORK_TREE when work tree is set, like $GIT_DIR, 2015-06-26). It has caused three regression reports so far. http://article.gmane.org/gmane.comp.version-control.git/281608 http://article.gmane.org/gmane.comp.version-control.git/281979 http://article.gmane.org/gmane.comp.version-control.git/282691 All of them are about spawning git subprocesses, where the new presence of GIT_WORK_TREE either changes command behaviour (git-init or git-clone), or how repo/worktree is detected (from aliases), with or without $GIT_DIR. The original bug will be re-fixed another way. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-09-28enter_repo: allow .git files in strict modeLibravatar Nguyễn Thái Ngọc Duy1-0/+10
Strict mode is about not guessing where .git is. If the user points to a .git file, we know exactly where the target .git dir will be. This makes it possible to serve .git files as repository on the server side. This may be needed even in local clone case because transport.c code uses upload-pack for fetching remote refs. But right now the clone/transport code goes with non-strict. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2015-09-28enter_repo: avoid duplicating logic, use is_git_directory() insteadLibravatar Nguyễn Thái Ngọc Duy1-0/+14
It matters for linked checkouts where 'refs' directory won't be available in $GIT_DIR. is_git_directory() knows about $GIT_COMMON_DIR and can handle this case. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2015-06-26setup: set env $GIT_WORK_TREE when work tree is set, like $GIT_DIRLibravatar Nguyễn Thái Ngọc Duy1-0/+17
In the test case, we run setup_git_dir_gently() the first time to read $GIT_DIR/config so that we can resolve aliases. We'll enter setup_discovered_git_dir() and may or may not call set_git_dir() near the end of the function, depending on whether the detected git dir is ".git" or not. This set_git_dir() will set env var $GIT_DIR. For normal repo, git dir detected via setup_discovered_git_dir() will be ".git", and set_git_dir() is not called. If .git file is used however, the git dir can't be ".git" and set_git_dir() is called and $GIT_DIR set. This is the key of this problem. If we expand an alias (or autocorrect command names), then setup_git_dir_gently() is run the second time. If $GIT_DIR is not set in the first run, we run the same setup_discovered_git_dir() as before. Nothing to see. If it is, however, we'll enter setup_explicit_git_dir() this time. This is where the "fun" is. If $GIT_WORK_TREE is not set but $GIT_DIR is, you are supposed to be at the root level of the worktree. But if you are in a subdir "foo/bar" (real worktree's top is "foo"), this rule bites you: your detected worktree is now "foo/bar", even though the first run correctly detected worktree as "foo". You get "internal error: work tree has already been set" as a result. Bottom line is, when $GIT_DIR is set, $GIT_WORK_TREE should be set too unless there's no work tree. But setting $GIT_WORK_TREE inside set_git_dir() may backfire. We don't know at that point if work tree is already configured by the caller. So set it when work tree is detected. It does not harm if $GIT_WORK_TREE is set while $GIT_DIR is not.

2008-09-30tests: grep portability fixesLibravatar Jeff King1-2/+2
We try to avoid using the "-q" or "-e" options, as they are largely useless, as explained in aadbe44f. There is one exception for "-e" here, which is in t7701 used to produce an "or" of patterns. This can be rewritten as an egrep pattern. This patch also removes use of "grep -F" in favor of the more widely available "fgrep".

2008-04-09Add platform-independent .git "symlink"Libravatar Lars Hjemli1-0/+103
This patch allows .git to be a regular textfile containing the path of the real git directory (prefixed with "gitdir: "), which can be useful on platforms lacking support for real symlinks. Signed-off-by: Lars Hjemli <hjemli@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
