2010-01-31Do not install shell libraries executableLibravatar Jonathan Nieder1-0/+0
Some scripts are expected to be sourced instead of executed on their own. Avoid some confusion by not marking them executable. The executable bit was confusing the valgrind support of our test scripts, which assumed that any executable without a #!-line should be intercepted and run through valgrind. So during valgrind-enabled tests, any script sourcing these files actually sourced the valgrind interception script instead.

2010-01-11Use $(git rev-parse --show-toplevel) in cd_to_toplevel().Libravatar Steven Drake1-14/+5
rev-parse --show-toplevel gives the absolute (aka "physical") path of the toplevel directory and is more portable as 'cd -P' is not supported by all shell implementations. This is also closer to what setup_work_tree() does. Signed-off-by: Steven Drake <sdrake@xnet.co.nz> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2009-11-23Protect scripted Porcelains from GREP_OPTIONS insanityLibravatar Junio C Hamano1-0/+8
If the user has exported the GREP_OPTIONS environment variable, the output from "grep" and "egrep" in scripted Porcelains may be different from what they expect. For example, we may want to count number of matching lines, by "grep" piped to "wc -l", and GREP_OPTIONS=-C3 will break such use. The approach taken by this change to address this issue is to protect only our own use of grep/egrep. Because we do not unset it at the beginning of our scripts, hook scripts run from the scripted Porcelains are exposed to the same insanity this environment variable causes when grep/egrep is used to implement logic (e.g. "grep | wc -l"), and it is entirely up to the hook scripts to protect themselves. On the other hand, applypatch-msg hook may want to show offending words in the proposed commit log message using grep to the end user, and the user might want to set GREP_OPTIONS=--color to paint the match more visibly. The approach to protect only our own use without unsetting the environment variable globally will allow this use case. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2009-06-10Makefile: insert SANE_TOOL_PATH to PATH before /bin or /usr/binLibravatar Junio C Hamano1-1/+27
In an earlier patch, we introduced SANE_TOOL_PATH that is prepended to user's PATH. This had an unintended consequence of overriding user's private binary directory that typically comes earlier in the PATH to holds even saner commands than whatever comes with the system. For example, a user may have ~/bin that is early in the path and contains a shell script "vi" that launches system's /bin/vi with specific options. Prepending SANE_TOOL_PATH to the PATH that happens to have "vi" in it defeats such customization. This fixes the issue by inserting SANE_TOOL_PATH just before /bin or /usr/bin appears on the PATH.

2009-06-06Makefile: introduce SANE_TOOL_PATH for prepending required elements to PATHLibravatar Junio C Hamano1-0/+2
Some platforms (like SunOS and family) have kept their common binaries at some historical moment in time, and introduced new binaries with modern features in a special location like /usr/xpg4/bin or /usr/ucb. Some of the features provided by these modern binaries are expected and required by git. If the featureful binaries are not in the users path, then git could end up using the less featureful binary and fail. So provide a mechanism to prepend elements to the users PATH at runtime so the modern binaries will be found.

2009-02-07git-sh-setup: Use "cd" option, not /bin/pwd, for symlinked work treeLibravatar Marcel M. Cary1-21/+8
In cd_to_toplevel, instead of 'cd $(unset PWD; /bin/pwd)/$path' use 'cd -P $path'. The "-P" option yields a desirable similarity to C chdir. While the "-P" option may be slightly less commonly supported than /bin/pwd, it is more concise, better tested, and less error prone. I've already added the 'unset PWD' to fix the /bin/pwd solution on BSD; there may be more edge cases out there. This still passes all the same test cases in t5521-pull-symlink.sh and t2300-cd-to-toplevel.sh, even before updating them to use 'pwd -P'. Signed-off-by: Junio C Hamano <gitster@pobox.com>

On Mac OS X and possibly BSDs, /bin/pwd reads PWD from the environment if available and shows the logical path by default rather than the physical one. Unset PWD before running /bin/pwd in both cd_to_toplevel and its test. Still use the external /bin/pwd because in my Bash on Linux, the builtin pwd prints the same result whether or not PWD is set.

2008-12-21git-sh-setup: Fix scripts whose PWD is a symlink into a git work-dirLibravatar Marcel M. Cary1-2/+21
I want directories of my working tree to be linked to from various paths on my filesystem where third-party components expect them, both in development and production environments. A build system's install step could solve this, but I develop scripts and web pages that don't need to be built. Git's submodule system could solve this, but we tend to develop, branch, and test those directories all in unison, so one big repository feels more natural. We prefer to edit and commit on the symlinked paths, not the canonical ones, and in that setting, "git pull" fails to find the top-level directory of the repository while other commands work fine. "git pull" fails because POSIX shells have a notion of current working directory that is different from getcwd(). The shell stores this path in PWD. As a result, "cd ../" can be interpreted differently in a shell script than chdir("../") in a C program. The shell interprets "../" by essentially stripping the last textual path component from PWD, whereas C chdir() follows the ".." link in the current directory on the filesystem. When PWD is a symlink, these are different destinations. As a result, Git's C commands find the correct top-level working tree, and shell scripts do not. Changes: * When interpreting a relative upward (../) path in cd_to_toplevel, prepend the cwd without symlinks, given by /bin/pwd * Add tests for cd_to_toplevel and "git pull" in a symlinked directory that failed before this fix, plus contrasting scenarios that already worked Signed-off-by: Marcel M.

We used to use "cat-file commit $commit" to extract the original author information from existing commit, but an earlier commit 5ac2715 (Consistent message encoding while reusing log from an existing commit) changed it to use "git show -s $commit". If you have a file in your work tree that can be interpreted as a valid object name (e.g. "HEAD"), this conversion will not work. Disambiguate by marking the end of revision parameter on the comand line with an explicit "--" to fix this. This breakage is most visible with rebase when a file called "HEAD" exists in the worktree.

The following values are possible for this variable: - "man" --> "man" program is used - "info" --> "info" program is used - "web" --> "git-browse-help" is used By default we still show help using "man". This patch also adds -m|--man command line option to use "man" to allow overriding the "help.format" configuration variable.

Quite a few of the scripts are rather careless about using GIT_DIR while changing directories. Some try their hands (with different likelihood of success) in making GIT_DIR absolute.

2007-08-01git-sh-setup.sh: make GIT_EDITOR/core.editor/VISUAL/EDITOR accept commandsLibravatar David Kastrup1-2/+3
The previous code only allowed specifying a single executable rather than a complete command like "emacsclient --alternate-editor vi" in those variables. Since VISUAL/EDITOR appear to be traditionally passed to a shell for interpretation (as corroborated with "less", "mail" and "mailx", while the really ancient "more" indeed allows only an executable name), the shell function git_editor has been amended appropriately. "eval" is employed to have quotes and similar interpreted _after_ expansion, so that specifying EDITOR='"/home/dak/My Commands/notepad.exe"' can be used for actually using commands with blanks. Instead of passing just the first argument of git_editor on, we pass all of them (so that +lineno might be employed at a later point of time, or so that multiple files may be edited when appropriate). Strictly speaking, there is a change in behavior: when git config core.editor returns a valid but empty string, the fallbacks are still searched. This is more consistent, and the old code was problematic with regard to multiple blanks. Putting in additional quotes might have worked, but quotes inside of command substitution inside of quotes is nasty enough to not reliably work the same across "Bourne shells".

2007-08-01Clean up work-tree handlingLibravatar Johannes Schindelin1-2/+1
The old version of work-tree support was an unholy mess, barely readable, and not to the point. For example, why do you have to provide a worktree, when it is not used? As in "git status". Now it works. Another riddle was: if you can have work trees inside the git dir, why are some programs complaining that they need a work tree? IOW it is allowed to call $ git --git-dir=../ --work-tree=. bla when you really want to. In this case, you are both in the git directory and in the working tree. So, programs have to actually test for the right thing, namely if they are inside a working tree, and not if they are inside a git directory. Also, GIT_DIR=../.git should behave the same as if no GIT_DIR was specified, unless there is a repository in the current working directory. It does now. The logic to determine if a repository is bare, or has a work tree (tertium non datur), is this: --work-tree=bla overrides GIT_WORK_TREE, which overrides core.bare = true, which overrides core.worktree, which overrides GIT_DIR/.. when GIT_DIR ends in /.git, which overrides the directory in which .git/ was found. In related news, a long standing bug was fixed: when in .git/bla/x.git/, which is a bare repository, git formerly assumed ../.. to be the appropriate git dir. This problem was reported by Shawn Pearce to have caused much pain, where a colleague mistakenly ran "git init" in "/" a long time ago, and bare repositories just would not work.

This is to be nicer to people with unusable GECOS field. "git-var -l" is currently broken in that when used by a user who does not have a usable GECOS field and has not corrected it by exporting GIT_COMMITTER_NAME environment variable it dies when it tries to output GIT_COMMITTER_IDENT (same thing for AUTHOR). "git-pull" used "git-var -l" only because it needed to get a configuration variable before "git-repo-config --get" was introduced. Use the latter tool designed exactly for this purpose. "git-sh-setup" used "git-var GIT_AUTHOR_IDENT" without actually wanting to use its value. The only purpose was to cause the command to check and barf if the repository format version recorded in the $GIT_DIR/config file is too new for us to deal with correctly. Instead, use "repo-config --get" on a random property and see if it die()s, and check if the exit status is 128 (comes from die -- missing variable is reported with exit status 1, so we can tell that case apart).

2005-12-14Usage message clean-up, take #2Libravatar Fredrik Kuivinen1-5/+29
There were some problems with the usage message clean-up patch series. I hadn't realised that subdirectory aware scripts can't source git-sh-setup. I propose that we change this and let the scripts which are subdirectory aware set a variable, SUBDIRECTORY_OK, before they source git-sh-setup. The scripts will also set USAGE and possibly LONG_USAGE before they source git-sh-setup. If LONG_USAGE isn't set it defaults to USAGE. If we go this way it's easy to catch --help in git-sh-setup, print the (long) usage message to stdout and exit cleanly. git-sh-setup can define a 'usage' shell function which can be called by the scripts to print the short usage string to stderr and exit non-cleanly. It will also be easy to change $0 to basename $0 or something else, if would like to do that sometime in the future. What follows is a patch to convert a couple of the commands to this style. If it's ok with everyone to do it this way I will convert the rest of the scripts too. [jc: thrown in to proposed updates queue for comments.] Signed-off-by: Junio C Hamano <junkio@cox.net>

Note that we export GIT_DIR explicitly when calling git-var; without it, the caller of this script would use GIT_DIR that we return (which is to assume ./.git unless the caller has it elsewhere) while git-var would go up to find a .git directory in our parent directories, which would be checking a different directory from what our callers will be using.

2005-10-08Create object subdirectories on demandLibravatar Linus Torvalds1-1/+1
This makes it possible to have a "sparse" git object subdirectory structure, something that has become much more attractive now that people use pack-files all the time. As a result of pack-files, a git object directory doesn't necessarily have any individual objects lying around, and in that case it's just wasting space to keep the empty first-level object directories around: on many filesystems the 256 empty directories will be aboue 1MB of diskspace. Even more importantly, after you re-pack a project that _used_ to be unpacked, you could be left with huge directories that no longer contain anything, but that waste space and take time to look through. With this change, "git prune-packed" can just do an rmdir() on the directories, and they'll get removed if empty, and re-created on demand. This patch also tries to fix up "write_sha1_from_fd()" to use the new common infrastructure for creating the object files, closing a hole where we might otherwise leave half-written objects in the object database. [jc: I unoptimized the part that really removes the fan-out directories to ease transition. init-db still wastes 1MB of diskspace to hold 256 empty fan-outs, and prune-packed rmdir()'s the grown but empty directories, but runs mkdir() immediately after that -- reducing the saving from 150KB to 146KB.

Revert and cherry-pick are just specialized forms of merge, and the requirements should be the same. Remove the 'general purpose routine to make sure tree is clean' from git-sh-setup, to prevent me from getting tempted again. Signed-off-by: Junio C Hamano <junkio@cox.net>
2005-09-12Fix CDPATH problem.Libravatar Junio C Hamano1-0/+6
CDPATH has two problems: * It takes scripts to unexpected places (somebody had CDPATH=..:../..:$HOME and the "cd" in git-clone.sh:get_repo_base took him to $HOME/.git when he said "clone foo bar" to clone a repository in "foo" which had "foo/.git"). CDPATH mechanism does not implicitly give "." at the beginning of CDPATH, which is the most irritating part. * The extra echo when it does its thing confuses scripts further. Most of our scripts that use "cd" includes git-sh-setup so the problem is primarily fixed there. git-clone starts without a repository, and it needs its own fix.
