2018-01-05submodule: submodule_move_head omits old argument in forced caseLibravatar Stefan Beller1-1/+3
When using hard reset or forced checkout with the option to recurse into submodules, the submodules need to be reset, too. It turns out that we need to omit the duplicate old argument to read-tree in all forced cases to omit the 2 way merge and use the more assertive behavior of reading the specific new tree into the index and updating the working tree.

2017-12-12submodule: convert get_next_submodule to not rely on the_indexLibravatar Brandon Williams1-10/+13
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.

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'.

2017-10-17implement fetching of moved submodulesLibravatar Heiko Voigt1-38/+100
We store the changed submodules paths to calculate which submodule needs fetching. This does not work for moved submodules since their paths do not stay the same in case of a moved submodules. In case of new submodules we do not have a path in the current checkout, since they just appeared in this fetch. It is more general to collect the submodule names for changes instead of their paths to include the above cases. If we do not have a configuration for a gitlink we rely on constructing a default name from the path if a git repository can be found at its path. We skip non-configured gitlinks whose default name collides with a configured one. With the change described above we implement 'on-demand' fetching of changes in moved submodules.

2017-10-01fsmonitor: teach git to optionally utilize a file system monitor to speed up ↵Libravatar Ben Peart1-1/+1
detecting new or changed files. When the index is read from disk, the fsmonitor index extension is used to flag the last known potentially dirty index entries. The registered core.fsmonitor command is called with the time the index was last updated and returns the list of files changed since that time. This list is used to flag any additional dirty cache entries and untracked cache directories. We can then use this valid state to speed up preload_index(), ie_match_stat(), and refresh_cache_ent() as they do not need to lstat() files to detect potential changes for those entries marked CE_FSMONITOR_VALID. In addition, if the untracked cache is turned on valid_cached_dir() can skip checking directories for new or changed files as fsmonitor will invalidate the cache only for those directories that have been identified as having potential changes. To keep the CE_FSMONITOR_VALID state accurate during git operations; when git updates a cache entry to match the current state on disk, it will now set the CE_FSMONITOR_VALID bit. Inversely, anytime git changes a cache entry, the CE_FSMONITOR_VALID bit is cleared and the corresponding untracked cache directory is marked invalid.

2017-09-28submodule: correct error message for missing commitsLibravatar Stefan Beller1-1/+1
When a submodule diff should be displayed we currently just add the submodule objects to the main object store and then e.g. walk the revision graph and create a summary for that submodule. It is possible that we are missing the submodule either completely or partially, which we currently differentiate with different error messages depending on whether (1) the whole submodule object store is missing or (2) just the needed for this particular diff. (1) is reported as "not initialized", and (2) is reported as "commits not present". If a submodule is deinit'ed its repository data is still around inside the superproject, such that the diff can still be produced. In that way the error message (1) is misleading as we can have a diff despite the submodule being not initialized. Downgrade the error message (1) to be the same as (2) and just say the commits are not present, as that is the true reason why the diff cannot be shown.

2017-09-24object_array: use `object_array_clear()`, not `free()`Libravatar Martin Ågren1-2/+2
Instead of freeing `foo.objects` for an object array `foo` (sometimes conditionally), call `object_array_clear(&foo)`. This means we don't poke as much into the implementation, which is already a good thing, but also that we release the individual entries as well, thereby fixing at least one memory-leak (in diff-lib.c). If someone is holding on to a pointer to an element's `name` or `path`, that is now a dangling pointer, i.e., we'd be turning an unpleasant situation into an outright bug. To the best of my understanding no such long-term pointers are being taken. The way we handle `study` in builting/reflog.c still looks like it might leak. That will be addressed in the next commit.

2017-09-14push, fetch: error out for submodule entries not pointing to commitsLibravatar Stefan Beller1-8/+25
The check_has_commit helper uses resolves a submodule entry to a commit, when validating its existence. As a side effect this means tolerates a submodule entry pointing to a tag, which is not a valid submodule entry that git commands would know how to cope with. Tighten the check to require an actual commit, not a tag pointing to a commit. Also improve the error handling when a submodule entry points to non-commit (e.g., a blob) to error out instead of warning and pretending the pointed to object doesn't exist.

2017-08-02submodule: don't use submodule_from_nameLibravatar Brandon Williams1-2/+0
The function 'submodule_from_name()' is being used incorrectly here as a submodule path is being used instead of a submodule name. Since the correct function to use with a path to a submodule is already being used ('submodule_from_path()') let's remove the call to 'submodule_from_name()'.

2017-08-02submodule: merge repo_read_gitmodules and gitmodules_configLibravatar Brandon Williams1-20/+17
Since 69aba5329 (submodule: add repo_read_gitmodules) there have been two ways to load a repository's .gitmodules file: 'repo_read_gitmodules()' is used if you have a repository object you are working with or 'gitmodules_config()' if you are implicitly working with 'the_repository'. Merge the logic of these two functions to remove duplicate code. In addition, 'repo_read_gitmodules()' can segfault by passing in a NULL pointer to 'git_config_from_file()' if a repository doesn't have a worktree. Instead check for the existence of a worktree before attempting to load the .gitmodules file. Signed-off-by: Brandon Williams <bmwill@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2017-08-02submodule: check for unmerged .gitmodules outside of config parsingLibravatar Brandon Williams1-24/+23
Add 'is_gitmodules_unmerged()' function which can be used to determine in the '.gitmodules' file is unmerged based on the passed in index instead of relying on a global variable which is set during the submodule-config parsing.

2017-08-02submodule: check for unstaged .gitmodules outside of config parsingLibravatar Brandon Williams1-15/+17
Teach 'is_staging_gitmodules_ok()' to be able to determine in the '.gitmodules' file has unstaged changes based on the passed in index instead of relying on a global variable which is set during the submodule-config parsing.
