Merge branch 'sb/submodule-move-nested'

2018-05-08T06:59:17Z

Moving a submodule that itself has submodule in it with "git mv" forgot to make necessary adjustment to the nested sub-submodules; now the codepath learned to recurse into the submodules. * sb/submodule-move-nested: submodule: fixup nested submodules after moving the submodule submodule-config: remove submodule_from_cache submodule-config: add repository argument to submodule_from_{name, path} submodule-config: allow submodule_free to handle arbitrary repositories grep: remove "repo" arg from non-supporting funcs submodule.h: drop declaration of connect_work_tree_and_git_dir

dir: convert struct untracked_cache_dir to object_id

2018-05-02T04:59:51Z

Convert the exclude_sha1 member of struct untracked_cache_dir and rename it to exclude_oid. Eliminate several hard-coded integral constants, and update a function name that referred to SHA-1. Signed-off-by: brian m. carlson Signed-off-by: Junio C Hamano

submodule: fixup nested submodules after moving the submodule

2018-03-29T16:44:51Z

connect_work_tree_and_git_dir is used to connect a submodule worktree with its git directory and vice versa after events that require a reconnection such as moving around the working tree. As submodules can have nested submodules themselves, we'd also want to fix the nested submodules when asked to. Add an option to recurse into the nested submodules and connect them as well. As submodules are identified by their name (which determines their git directory in relation to their superproject's git directory) internally and by their path in the working tree of the superproject, we need to make sure that the mapping of name <-> path is kept intact. We can do that in the git-mv command by writing out the gitmodules file first and then forcing a reload of the submodule config machinery.

Merge branch 'nd/fix-untracked-cache-invalidation'

2018-02-27T18:33:50Z

Some bugs around "untracked cache" feature have been fixed. * nd/fix-untracked-cache-invalidation: dir.c: ignore paths containing .git when invalidating untracked cache dir.c: stop ignoring opendir() error in open_cached_dir() dir.c: fix missing dir invalidation in untracked code dir.c: avoid stat() in valid_cached_dir() status: add a failing test showing a core.untrackedCache bug

dir.c: ignore paths containing .git when invalidating untracked cache

2018-02-07T20:27:02Z

read_directory() code ignores all paths named ".git" even if it's not a valid git repository. See treat_path() for details. Since ".git" is basically invisible to read_directory(), when we are asked to invalidate a path that contains ".git", we can safely ignore it because the slow path would not consider it anyway. This helps when fsmonitor is used and we have a real ".git" repo at worktree top. Occasionally .git/index will be updated and if the fsmonitor hook does not filter it, untracked cache is asked to invalidate the path ".git/index". Without this patch, we invalidate the root directory unncessarily, which: - makes read_directory() fall back to slow path for root directory (slower) - makes the index dirty (because UNTR extension is updated). Depending on the index size, writing it down could also be slow. A note about the new "safe_path" knob. Since this new check could be relatively expensive, avoid it when we know it's not needed. If the path comes from the index, it can't contain ".git". If it does contain, we may be screwed up at many more levels, not just this one.

dir: convert struct sha1_stat to use object_id

2018-01-30T18:42:36Z

Convert the declaration of struct sha1_stat. Adjust all usages of this struct and replace hash{clr,cmp,cpy} with oid{clr,cmp,cpy} wherever possible. Rename it to struct oid_stat. Rename static function load_sha1_stat to load_oid_stat. Remove macro EMPTY_BLOB_SHA1_BIN, as it's no longer used. Signed-off-by: Patryk Obara Signed-off-by: Junio C Hamano

Merge branch 'jh/object-filtering'

2017-12-27T19:16:21Z

In preparation for implementing narrow/partial clone, the object walking machinery has been taught a way to tell it to "filter" some objects from enumeration. * jh/object-filtering: rev-list: support --no-filter argument list-objects-filter-options: support --no-filter list-objects-filter-options: fix 'keword' typo in comment pack-objects: add list-objects filtering rev-list: add list-objects filtering support list-objects: filter objects in traverse_commit_list oidset: add iterator methods to oidset oidmap: add oidmap iterator methods dir: allow exclusions from blob in addition to file

dir: allow exclusions from blob in addition to file

2017-11-22T05:11:56Z

Refactor add_excludes() to separate the reading of the exclude file into a buffer and the parsing of the buffer into exclude_list items. Add add_excludes_from_blob_to_list() to allow an exclude file be specified with an OID without assuming a local worktree or index exists. Refactor read_skip_worktree_file_from_index() and add do_read_blob() to eliminate duplication of preliminary processing of blob contents.
