The infrastructure to rewrite "git submodule" in C is being built incrementally. Let's polish these early parts well enough and make them graduate to 'next' and 'master', so that the more involved follow-up can start cooking on a solid ground. * sb/submodule-helper: submodule: rewrite `module_clone` shell function in C submodule: rewrite `module_name` shell function in C submodule: rewrite `module_list` shell function in C

submodule: allow only certain protocols for submodule fetches

2015-09-23T18:35:48Z

Some protocols (like git-remote-ext) can execute arbitrary code found in the URL. The URLs that submodules use may come from arbitrary sources (e.g., .gitmodules files in a remote repository). Let's restrict submodules to fetching from a known-good subset of protocols. Note that we apply this restriction to all submodule commands, whether the URL comes from .gitmodules or not. This is more restrictive than we need to be; for example, in the tests we run: git submodule add ext::... which should be trusted, as the URL comes directly from the command line provided by the user. But doing it this way is simpler, and makes it much less likely that we would miss a case. And since such protocols should be an exception (especially because nobody who clones from them will be able to update the submodules!), it's not likely to inconvenience anyone in practice.

submodule: rewrite `module_clone` shell function in C

2015-09-08T22:48:21Z

This reimplements the helper function `module_clone` in shell in C as `clone`. This functionality is needed for converting `git submodule update` later on, which we want to add threading to. Signed-off-by: Stefan Beller Signed-off-by: Junio C Hamano

submodule: rewrite `module_name` shell function in C

2015-09-03T21:12:40Z

This implements the helper `name` in C instead of shell, yielding a nice performance boost. Before this patch, I measured a time (best out of three): $ time ./t7400-submodule-basic.sh >/dev/null real 0m11.066s user 0m3.348s sys 0m8.534s With this patch applied I measured (also best out of three) $ time ./t7400-submodule-basic.sh >/dev/null real 0m10.063s user 0m3.044s sys 0m7.487s Signed-off-by: Stefan Beller Signed-off-by: Junio C Hamano

submodule: rewrite `module_list` shell function in C

2015-09-03T21:12:40Z

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. Signed-off-by: Stefan Beller Signed-off-by: Junio C Hamano
