A v3 of a refactoring of tree.c. See v2 at https://lore.kernel.org/git/20210308022138.28166-1-avarab@xxxxxxxxx/ This brings back pretty much the old read_tree_recursive() under the name read_tree_at() as suggested in https://lore.kernel.org/git/xmqqft106sok.fsf@gitster.g/ Ævar Arnfjörð Bjarmason (9): ls-files tests: add meaningful --with-tree tests tree.c API: move read_tree() into builtin/ls-files.c ls-files: don't needlessly pass around stage variable ls-files: refactor away read_tree() tree.h API: remove support for starting at prefix != "" tree.h API: remove "stage" parameter from read_tree_recursive() tree.h API: rename read_tree_recursive() to read_tree() show tests: add test for "git show <tree>" tree.h API: expose read_tree_1() as read_tree_at() archive.c | 19 +++--- builtin/checkout.c | 8 +-- builtin/log.c | 8 +-- builtin/ls-files.c | 76 +++++++++++++++++++++- builtin/ls-tree.c | 6 +- cache.h | 2 +- merge-recursive.c | 6 +- t/t3060-ls-files-with-tree.sh | 41 ++++++++++++ t/t7007-show.sh | 39 ++++++++++++ tree.c | 117 ++++------------------------------ tree.h | 24 +++---- 11 files changed, 205 insertions(+), 141 deletions(-) Range-diff: 1: 6416da0dee2 = 1: b338f2c01a4 ls-files tests: add meaningful --with-tree tests 2: 765001b44cd ! 2: 4578b83944c tree.c API: move read_tree() into builtin/ls-files.c @@ builtin/ls-files.c: static int get_common_prefix_len(const char *common_prefix) * Read the tree specified with --with-tree option * (typically, HEAD) into stage #1 and then + ## cache.h ## +@@ cache.h: static inline int index_pos_to_insert_pos(uintmax_t pos) + #define ADD_CACHE_OK_TO_ADD 1 /* Ok to add */ + #define ADD_CACHE_OK_TO_REPLACE 2 /* Ok to replace file/directory */ + #define ADD_CACHE_SKIP_DFCHECK 4 /* Ok to skip DF conflict checks */ +-#define ADD_CACHE_JUST_APPEND 8 /* Append only; tree.c::read_tree() */ ++#define ADD_CACHE_JUST_APPEND 8 /* Append only */ + #define ADD_CACHE_NEW_ONLY 16 /* Do not replace existing ones */ + #define ADD_CACHE_KEEP_CACHE_TREE 32 /* Do not invalidate cache-tree */ + #define ADD_CACHE_RENORMALIZE 64 /* Pass along HASH_RENORMALIZE */ + ## tree.c ## @@ 3: a71ffba7d04 = 3: 33656ff63b8 ls-files: don't needlessly pass around stage variable 4: e78d1810b89 = 4: 1c96d5d3611 ls-files: refactor away read_tree() 5: 05eecdd7519 ! 5: 367cb99224b tree.h API: remove support for starting at prefix != "" @@ Commit message ffd31f661d5 (Reimplement read_tree_recursive() using tree_entry_interesting(), 2011-03-25). - If in the future we need to support recursively reading trees without - starting at the root we can easily add a read_tree_recursive_subdir(), - and make that function a thin wrapper for read_tree_1(). + As it turns out (Murphy's law and all) we're just about to gain a new + in-tree user that would need this parameter[1].
