2017-12-12submodule: convert get_next_submodule to not rely on the_indexLibravatar Brandon Williams1-4/+6
Instead of implicitly relying on the global 'the_index', convert 'get_next_submodule()' to use the index of the repository stored in the callback data 'struct submodule_parallel_fetch'. Since this removes the last user of the index compatibility macros, define 'NO_THE_INDEX_COMPATIBILITY_MACROS' to prevent future users of these macros in submodule.c.

2017-12-12submodule: used correct index in is_staging_gitmodules_okLibravatar Brandon Williams1-1/+1
Commit 883e248b8 (fsmonitor: teach git to optionally utilize a file system monitor to speed up detecting new or changed files., 2017-09-22) introduced a call to 'ce_match_stat()' in 'is_staging_gitmodules_ok()' which implicitly relys on the the global 'the_index' instead of the passed in 'struct index_state'. Fix this by changing the call to 'ie_match_stat()' and using the passed in index_state struct. Signed-off-by: Brandon Williams <bmwill@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-06-30submodule.c: migrate diff output to use emit_diff_symbolLibravatar Stefan Beller1-9/+4
As the submodule process is no longer attached to the same file pointer 'o->file' as the superprojects process, there is a different result in color.c::check_auto_color. That is why we need to pass coloring explicitly, such that the submodule coloring decision will be made by the child process processing the submodule. Only DIFF_SYMBOL_SUBMODULE_PIPETHROUGH contains color, the other symbols are for embedding the submodule output into the superprojects output. Remove the colors from the function signatures, as all the coloring decisions will be made either inside the child process or the final emit_diff_symbol, but not in the functions driving the submodule diff.

2017-06-23pull: optionally rebase submodules (remote submodule changes only)Libravatar Stefan Beller1-0/+4
Teach pull to optionally update submodules when '--recurse-submodules' is provided. This will teach pull to run 'submodule update --rebase' when the '--recurse-submodules' and '--rebase' flags are given under specific circumstances. On a rebase workflow: ===================== 1. Both sides change the submodule ------------------------------ Let's assume the following history in a submodule: H---I---J---K---L local branch \ M---N---O---P remote branch and the following in the superproject (recorded submodule in parens): A(H)---B(I)---F(K)---G(L) local branch \ C(N)---D(N)---E(P) remote branch In an ideal world this would rebase the submodule and rewrite the submodule pointers that the superproject points at such that the superproject looks like A(H)---B(I) F(K')---G(L') rebased branch \ / C(N)---D(N)---E(P) remote branch and the submodule as: J---K---L (old dangeling tip) / H---I J'---K'---L' rebased branch \ / M---N---O---P remote branch And if a conflict arises in the submodule the superproject rebase would stop at that commit at which the submodule conflict occurs. Currently a "pull --rebase" in the superproject produces a merge conflict as the submodule pointer changes are conflicting and cannot be resolved. 2. Local submodule changes only ----------------------- Assuming histories as above, except that the remote branch would not contain submodule changes, then a result as A(H)---B(I) F(K)---G(L) rebased branch \ / C(I)---D(I)---E(I) remote branch is desire-able. This is what currently happens in rebase. If the recursive flag is given, the ideal git would produce a superproject as: A(H)---B(I) F(K')---G(L') rebased branch (incl. sub rebase!) \ / C(I)---D(I)---E(I) remote branch and the submodule as: J---K---L (old dangeling tip) / H---I J'---K'---L' locally rebased branch \ / M---N---O---P advanced branch This patch doesn't address this issue, however a test is added that this fails up front. 3. Remote submodule changes only ---------------------- Assuming histories as in (1) except that the local superproject branch would not have touched the submodule the rebase already works out in the superproject with no conflicts: A(H)---B(I) F(P)---G(P) rebased branch (no sub changes) \ / C(N)---D(N)---E(P) remote branch The recurse flag as presented in this patch would additionally update the submodule as: H---I J'---K'---L' rebased branch \ / M---N---O---P remote branch As neither J, K, L nor J', K', L' are referred to from the superproject, no rewriting of the superproject commits is required. Conclusion for 'pull --rebase --recursive' ----------------------------------------- If there are no local superproject changes it is sufficient to call "submodule update --rebase" as this produces the desired results. In case of conflicts, the behavior is the same as in 'submodule update --recursive' which is assumed to be sane. This patch implements (3) only. On a merge workflow: ==================== We'll start off with the same underlying DAG as in (1) in the rebase workflow. So in an ideal world a 'pull --merge --recursive' would produce this: H---I---J---K---L----X \ / M---N---O---P with X as the new merge-commit in the submodule and the superproject as: A(H)---B(I)---F(K)---G(L)---Y(X) \ / C(N)---D(N)---E(P) However modifying the submodules on the fly is not supported in git-merge such that Y(X) is not easy to produce in a single patch. In fact git-merge doesn't know about submodules at all. However when at least one side does not contain commits touching the submodule at all, then we do not need to perform the merge for the submodule but a fast-forward can be done via checking out either L or P in the submodule. This strategy is implemented in 68d03e4a6e (Implement automatic fast-forward merge for submodules, 2010-07-07) already, so to align with the rebase behavior we need to also update the worktree of the submodule.

2017-05-30reset/checkout/read-tree: unify config callback for submodule recursionLibravatar Stefan Beller1-1/+5
The callback function is essentially duplicated 3 times. Remove all of them and offer a new callback function, that lives in submodule.c By putting the callback function there, we no longer need the function 'set_config_update_recurse_submodules', nor duplicate the global variable in each builtin as well as submodule.c In the three builtins we have different 2 ways how to load the .gitmodules and config file, which are slightly different. git-checkout has to load the submodule config all the time due to 23b4c7bcc5 (checkout: Use submodule.*.ignore settings from .git/config and .gitmodules, 2010-08-28) git-reset and git-read-tree do not respect these diff settings, so loading the submodule configuration is optional.

Since the stripping the trailing slash is no longer necessary, remove the PATHSPEC_STRIP_SUBMODULE_SLASH_EXPENSIVE flag. In addition, factor out the logic which dies if a path decends into a submodule so that it can still be used as a check after a pathspec struct has been initialized.

2017-03-15submodules: introduce check to see whether to touch a submoduleLibravatar Stefan Beller1-0/+7
In later patches we introduce the --recurse-submodule flag for commands that modify the working directory, e.g. git-checkout. It is potentially expensive to check if a submodule needs an update, because a common theme to interact with submodules is to spawn a child process for each interaction. So let's introduce a function that checks if a submodule needs to be checked for an update before attempting the update.

2017-03-15update submodules: add a config option to determine if submodules are updatedLibravatar Stefan Beller1-0/+1
In later patches we introduce the options and flag for commands that modify the working directory, e.g. git-checkout. Have a central place to store such settings whether we want to update a submodule. Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-03-08rev-parse: add --show-superproject-working-treeLibravatar Stefan Beller1-0/+8
In some situations it is useful to know if the given repository is a submodule of another repository. Add the flag --show-superproject-working-tree to git-rev-parse to make it easy to find out if there is a superproject. When no superproject exists, the output will be empty.

"git rm" used to refuse to remove a submodule when it has its own git repository embedded in its working tree. It learned to move the repository away to $GIT_DIR/modules/ of the superproject instead, and allow the submodule to be deleted (as long as there will be no loss of local modifications, that is). * sb/submodule-rm-absorb: rm: absorb a submodules git dir before deletion submodule: rename and add flags to ok_to_remove_submodule submodule: modernize ok_to_remove_submodule to use argv_array submodule.h: add extern keyword to functions

2016-12-27submodule: rename and add flags to ok_to_remove_submoduleLibravatar Stefan Beller1-1/+5
In different contexts the question "Is it ok to delete a submodule?" may be answered differently. In 293ab15eea (submodule: teach rm to remove submodules unless they contain a git directory, 2012-09-26) a case was made that we can safely ignore ignored untracked files for removal as we explicitely ask for the removal of the submodule. In a later patch we want to remove submodules even when the user doesn't explicitly ask for it (e.g. checking out a tree-ish in which the submodule doesn't exist). In that case we want to be more careful when it comes to deletion of untracked files. As of this patch it is unclear how this will be implemented exactly, so we'll offer flags in which the caller can specify how the different untracked files ought to be handled. As the flags allow the function to not die on an error when spawning a child process, we need to find an appropriate return code for the case when the child process could not be started. As in that case we cannot tell if the submodule is ok to remove, we'd want to return 'false'. As only 0 is understood as false, rename the function to invert the meaning, i.e. the return code of 0 signals the removal of the submodule is fine, and other values can be used to return a more precise answer what went wrong.
