2017-10-07submodule: port submodule subcommand 'status' from shell to CLibravatar Prathamesh Chavan1-0/+198
This aims to make git-submodule 'status' a built-in. Hence, the function cmd_status() is ported from shell to C. This is done by introducing four functions: module_status(), submodule_status_cb(), submodule_status() and print_status(). The function module_status() acts as the front-end of the subcommand. It parses subcommand's options and then calls the function module_list_compute() for computing the list of submodules. Then this functions calls for_each_listed_submodule() looping through the list obtained. Then for_each_listed_submodule() calls submodule_status_cb() for each of the submodule in its list. The function submodule_status_cb() calls submodule_status() after passing appropriate arguments to the funciton. Function submodule_status() is responsible for generating the status each submodule it is called for, and then calls print_status(). Finally, the function print_status() handles the printing of submodule's status. Function set_name_rev() is also ported from git-submodule to the submodule--helper builtin function compute_rev_name(), which now generates the value of the revision name as required.

2017-09-22consistently use "fallthrough" comments in switchesLibravatar Jeff King1-0/+1
Gcc 7 adds -Wimplicit-fallthrough, which can warn when a switch case falls through to the next case. The general idea is that the compiler can't tell if this was intentional or not, so you should annotate any intentional fall-throughs as such, leaving it to complain about any unannotated ones. There's a GNU __attribute__ which can be used for annotation, but of course we'd have to #ifdef it away on non-gcc compilers. Gcc will also recognize specially-formatted comments, which matches our current practice. Let's extend that practice to all of the unannotated sites (which I did look over and verify that they were behaving as intended). Ideally in each case we'd actually give some reasons in the comment about why we're falling through, or what we're falling through to. And gcc does support that with -Wimplicit-fallthrough=2, which relaxes the comment pattern matching to anything that contains "fallthrough" (or a variety of spelling variants). However, this isn't the default for -Wimplicit-fallthrough, nor for -Wextra. In the name of simplicity, it's probably better for us to support the default level, which requires "fallthrough" to be the only thing in the comment (modulo some window dressing like "else" and some punctuation; see the gcc manual for the complete set of patterns). This patch suppresses all warnings due to -Wimplicit-fallthrough. We might eventually want to add that to the DEVELOPER Makefile knob, but we should probably wait until gcc 7 is more widely adopted (since earlier versions will complain about the unknown warning type).

2017-07-21run_processes_parallel: change confusing task_cb conventionLibravatar Johannes Schindelin1-1/+1
By declaring the task_cb parameter of type `void **`, the signature of the get_next_task method suggests that the "task-specific cookie" can be defined in that method, and the signatures of the start_failure and of the task_finished methods declare that parameter of type `void *`, suggesting that those methods are mere users of said cookie. That convention makes a total lot of sense, because the tasks are pretty much dead when one of the latter two methods is called: there would be little use to reset that cookie at that point because nobody would be able to see the change afterwards. However, this is not what the code actually does. For all three methods, it passes the *address* of pp->children[i].data. As reasoned above, this behavior makes no sense. So let's change the implementation to adhere to the convention suggested by the signatures.

2017-07-20submodule--helper: teach push-check to handle HEADLibravatar Brandon Williams1-9/+40
In 06bf4ad1d (push: propagate remote and refspec with --recurse-submodules) push was taught how to propagate a refspec down to submodules when the '--recurse-submodules' flag is given. The only refspecs that are allowed to be propagated are ones which name a ref which exists in both the superproject and the submodule, with the caveat that 'HEAD' was disallowed. This patch teaches push-check (the submodule helper which determines if a refspec can be propagated to a submodule) to permit propagating 'HEAD' if and only if the superproject and the submodule both have the same named branch checked out and the submodule is not in a detached head state.

2017-02-28submodule init: warn about falling back to a local pathLibravatar Stefan Beller1-5/+3
When a submodule is initialized, the config variable 'submodule.<name>.url' is set depending on the value of the same variable in the .gitmodules file. When the URL indicates to be relative, then the url is computed relative to its default remote. The default remote cannot be determined accurately in all cases, such that it falls back to 'origin'. The 'origin' remote may not exist, though. In that case we give up looking for a suitable remote and we'll just assume it to be a local relative path. This can be confusing to users as there is a lot of guessing involved, which is not obvious to the user. So in the corner case of assuming a local autoritative truth, warn the user to lessen the confusion. This behavior was introduced in 4d6893200 (submodule add: allow relative repository path even when no url is set, 2011-06-06), which shared the code with submodule-init and then ported to C in 3604242f080a (submodule: port init from shell to C, 2016-04-15). In case of submodule-add, this behavior makes sense in some use cases[1], however for submodule-init there does not seem to be an immediate obvious use case to fall back to a local submodule. However there might be, so warn instead of die here. While adding the warning, also clarify the behavior of relative URLs in the documentation.

Code cleanup. * rs/absolute-pathdup: use absolute_pathdup() abspath: add absolute_pathdup()
2017-01-27use absolute_pathdup()Libravatar René Scharfe1-1/+1
Apply the semantic patch for converting callers that duplicate the result of absolute_path() to call absolute_pathdup() instead, which avoids an extra string copy to a static buffer. Signed-off-by: Rene Scharfe <l.s.r@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Error message fix. * sb/submodule-init: submodule update --init: display correct path from submodule
2017-01-12submodule update --init: display correct path from submoduleLibravatar Stefan Beller1-6/+7
In the submodule helper we did not correctly handled the display path for initializing submodules when both the submodule is inside a subdirectory as well as the command being invoked from a subdirectory (as viewed from the superproject). This was broken in 3604242f080, which was written at a time where there was no super-prefix available, so we abused the --prefix option for the same purpose and could get only one case right (the call from within a subdirectory, not the submodule being in a subdirectory).

A new submodule helper "git submodule embedgitdirs" to make it easier to move embedded .git/ directory for submodules in a superproject to .git/modules/ (and point the latter with the former that is turned into a "gitdir:" file) has been added. * sb/submodule-embed-gitdir: worktree: initialize return value for submodule_uses_worktrees submodule: add absorb-git-dir function move connect_work_tree_and_git_dir to dir.h worktree: check if a submodule uses worktrees test-lib-functions.sh: teach test_commit -C <dir> submodule helper: support super prefix submodule: use absolute path for computing relative path connecting
