git-sh-setup: Use "cd" option, not /bin/pwd, for symlinked work tree

2009-02-07T08:45:29Z

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

git-sh-setup: Fix scripts whose PWD is a symlink to a work-dir on OS X

2009-01-05T19:46:58Z

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.

git-sh-setup: Fix scripts whose PWD is a symlink into a git work-dir

2008-12-21T09:10:48Z

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.

Make usage strings dash-less

2008-07-13T21:12:48Z

When you misuse a git command, you are shown the usage string. But this is currently shown in the dashed form. So if you just copy what you see, it will not work, when the dashed form is no longer supported. This patch makes git commands show the dash-less version. For shell scripts that do not specify OPTIONS_SPEC, git-sh-setup.sh generates a dash-less usage string now. Signed-off-by: Stephan Beyer Signed-off-by: Junio C Hamano

Windows: Work around incompatible sort and find.

2008-06-26T06:45:09Z

If the PATH lists the Windows system directories before the MSYS directories, Windows's own incompatible sort and find commands would be picked up. We implement these commands as functions and call the real tools by absolute path. Signed-off-by: Johannes Sixt

Protect get_author_ident_from_commit() from filenames in work tree

2008-02-13T21:43:02Z

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.

shell-scripts usage(): consistently exit with non-zero

2007-12-20T20:58:06Z

Earlier conversion of shell scripts to parse-options made usage() to run "git cmd -h" which in turn emit LONG_USAGE and exit with 0 status. This is inconsistent with the scripts that do not use parse-options, whose usage() died with the message, exiting with 1. Signed-off-by: Junio C Hamano

git-help: add "help.format" config variable.

2007-12-15T05:58:35Z

This config variable makes it possible to choose the default format used to display help. This format will be used only if no option like -a|--all|-i|--info|-m|--man|-w|--web is passed to "git-help". 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. Note that this patch also revert some recent changes in "git-browse-help" because they prevented to look for config variables in the global configuration file.

git-help -w: do not require to be in git repository

2007-12-13T01:41:58Z

The users used to be able to say "git help cat-file" from anywhere, but the browse-help script insisted to be in a git repository, which caused "git help -w cat-file" to barf outside. Correct it. While at it, remove leftover debugging "echo". Signed-off-by: Junio C Hamano
