From fada767463b599951b37bd544379a1d18dcf9370 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Fri, 29 May 2015 02:49:10 -0400 Subject: setup_git_directory: delay core.bare/core.worktree errors MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If both core.bare and core.worktree are set, we complain about the bogus config and die. Dying is good, because it avoids commands running and doing damage in a potentially incorrect setup. But dying _there_ is bad, because it means that commands which do not even care about the work tree cannot run. This can make repairing the situation harder: [setup] $ git config core.bare true $ git config core.worktree /some/path [OK, expected.] $ git status fatal: core.bare and core.worktree do not make sense [Hrm...] $ git config --unset core.worktree fatal: core.bare and core.worktree do not make sense [Nope...] $ git config --edit fatal: core.bare and core.worktree do not make sense [Gaaah.] $ git help config fatal: core.bare and core.worktree do not make sense Instead, let's issue a warning about the bogus config when we notice it (i.e., for all commands), but only die when the command tries to use the work tree (by calling setup_work_tree). So we now get: $ git status warning: core.bare and core.worktree do not make sense fatal: unable to set up work tree using invalid config $ git config --unset core.worktree warning: core.bare and core.worktree do not make sense We have to update t1510 to accomodate this; it uses symbolic-ref to check whether the configuration works or not, but of course that command does not use the working tree. Instead, we switch it to use `git status`, as it requires a work-tree, does not need any special setup, and is read-only (so a failure will not adversely affect further tests). In addition, we add a new test that checks the desired behavior (i.e., that running "git config" with the bogus config does in fact work).
