| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The point of having a whitelist of command-line config options to pass to submodules was two-fold: 1. It prevented obvious nonsense like using core.worktree for multiple repos. 2. It could prevent surprise when the user did not mean for the options to leak to the submodules (e.g., http.sslverify=false). For case 1, the answer is mostly "if it hurts, don't do that". For case 2, we can note that any such example has a matching inverted surprise (e.g., a user who meant http.sslverify=true to apply everywhere, but it didn't). So this whitelist is probably not giving us any benefit, and is already creating a hassle as people propose things to put on it. Let's just drop it entirely. Note that we still need to keep a special code path for "prepare the submodule environment", because we still have to take care to pass through $GIT_CONFIG_PARAMETERS (and block the rest of the repo-specific environment variables). We can do this easily from within the submodule shell script, which lets us drop the submodule--helper option entirely (and it's OK to do so because as a "--" program, it is entirely a private implementation detail).

| * submodule--helper: move config-sanitizing to submodule.cJeff King2016-04-281-48/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | These functions should be used by any code which spawns a submodule process, which may happen in submodule.c (e.g., for spawning fetch). Let's move them there and make them public so that submodule--helper can continue to use them. Since they're now public, let's also provide a basic overview of their intended use.

| * git: submodule honor -c credential.* from command lineJacob Keller2016-03-011-1/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to the way that the git-submodule code works, it clears all local git environment variables before entering submodules. This is normally a good thing since we want to clear settings such as GIT_WORKTREE and other variables which would affect the operation of submodule commands. However, GIT_CONFIG_PARAMETERS is special, and we actually do want to preserve these settings. However, we do not want to preserve all configuration as many things should be left specific to the parent project. Add a git submodule--helper function, sanitize-config, which shall be used to sanitize GIT_CONFIG_PARAMETERS, removing all key/value pairs except a small subset that are known to be safe and necessary. Replace all the calls to clear_local_git_env with a wrapped function that filters GIT_CONFIG_PARAMETERS using the new helper and then restores it to the filtered subset after clearing the rest of the environment.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The git submodule--helper clone command will fail with a segmentation fault when given a null url or null path variable. Since these are required for proper functioning of the submodule--helper clone subcommand, add checks to prevent running and fail gracefully when missing. Update the usage string to reflect the requirement that the --url and --path "options" are required.

This regression was introduced in 74703a1e4dfc (submodule: rewrite `module_list` shell function in C, 2015-09-02), as we changed the order of checking in new module listing to first check whether it is a gitlin before feeding it to match_pathspec(). It used to be that a pathspec that does not match any path were diagnosed as an error, but the new code complains for a pathspec that does not match any submodule path. Arguably the new behaviour may give us a better diagnosis, but that is inconsistent with the suggestion "deinit" gives, and also this was an unintended accident. The new behaviour hopefully can be redesigned and implemented better in future releases, but for now, switch these two checks to restore the same behavior as before. In an empty repository, giving the pathspec '.' will still get the same "did not match" error, but that is the same bug we had before 1.7.0.

* submodule: rewrite `module_list` shell function in CStefan Beller2015-09-031-0/+128
Most of the submodule operations work on a set of submodules. Calculating and using this set is usually done via: module_list "$@" | { while read mode sha1 stage sm_path do # the actual operation done } Currently the function `module_list` is implemented in the git-submodule.sh as a shell script wrapping a perl script. The rewrite is in C, such that it is faster and can later be easily adapted when other functions are rewritten in C. git-submodule.sh, similar to the builtin commands, will navigate to the top-most directory of the repository and keep the subdirectory as a variable. As the helper is called from within the git-submodule.sh script, we are already navigated to the root level, but the path arguments are still relative to the subdirectory we were in when calling git-submodule.sh. That's why there is a `--prefix` option pointing to an alternative path which to anchor relative path arguments.
