use only the $PATH for exec'ing git commands

2007-10-30T03:51:37Z

We need to correctly set up $PATH for non-c based git commands. Since we already do this, we can just use that $PATH and execvp, instead of looping over the paths with execve. This patch adds a setup_path() function to exec_cmd.c, which sets the $PATH order correctly for our search order. execv_git_cmd() is stripped down to setting up argv and calling execvp(). git.c's main() only only needs to call setup_path().

"current_exec_path" is a misleading name, use "argv_exec_path"

Const tightening.

Mark Wooding noticed there was a type mismatch warning in git.c; this patch does things slightly differently (mostly tightening const) and was what I was holding onto, waiting for the setup-revisions change to be merged into the master branch. Signed-off-by: Junio C Hamano

Exec git programs without using PATH.

2006-01-14T00:49:01Z

The git suite may not be in PATH (and thus programs such as git-send-pack could not exec git-rev-list). Thus there is a need for logic that will locate these programs. Modifying PATH is not desirable as it result in behavior differing from the user's intentions, as we may end up prepending "/usr/bin" to PATH. - git C programs will use exec*_git_cmd() APIs to exec sub-commands. - exec*_git_cmd() will execute a git program by searching for it in the following directories: 1. --exec-path (as used by "git") 2. The GIT_EXEC_PATH environment variable. 3. $(gitexecdir) as set in Makefile (default value $(bindir)). - git wrapper will modify PATH as before to enable shell scripts to invoke "git-foo" commands. Ideally, shell scripts should use the git wrapper to become independent of PATH, and then modifying PATH will not be necessary.
