__git_ps1() runs the '$(git symbolic-ref HEAD)' command substitution to find out whether we are on a branch and to find out the name of that branch. This imposes the overhead of fork()ing a subshell and fork()+exec()ing a git process. Since HEAD is in most cases a single-line file and the symbolic ref format is quite simple to recognize and parse, read and parse it using only bash builtins, thereby sparing all that fork()+exec() overhead. Don't display the git prompt if reading HEAD fails, because a readable HEAD is required for a git repository. HEAD can also be a symlink symbolic ref (due to 'core.preferSymlinkRefs'), so use bash builtins for reading HEAD only when HEAD is not a symlink. Signed-off-by: SZEDER Gábor <szeder@ira.uka.de> |
