If there are any the resolution should be\ntrivially validated by running the cocci rule on \"theirs\" and keeping\nthat version.\n\nBranch & passing CI at:\nhttps://github.com/avar/git/tree/avar/narrow-down-the-index-compatibilty-macros\n\nÆvar Arnfjörð Bjarmason (12):\n cache.h: remove unused \"the_index\" compat macros\n builtin/{grep,log}.: don't define \"USE_THE_INDEX_COMPATIBILITY_MACROS\"\n cocci & cache.h: remove rarely used \"the_index\" compat macros\n read-cache API & users: make discard_index() return void\n cocci: add a index-compatibility.pending.cocci\n cocci & cache.h: apply a selection of \"pending\" index-compatibility\n cocci & cache.h: apply variable section of \"pending\"\n index-compatibility\n cocci: apply \"pending\" index-compatibility to \"t/helper/*.c\"\n {builtin/*,repository}.c: add & use \"USE_THE_INDEX_VARIABLE\"\n cache.h & test-tool.h: add & use \"USE_THE_INDEX_VARIABLE\"\n cocci: apply \"pending\" index-compatibility to some \"builtin/*.c\"\n builtin/*: remove or amend \"USE_THE_INDEX_COMPATIBILITY_MACROS\"\n\n add-interactive.c | 8 +-\n add-patch.c | 3 +-\n builtin/add.c | 21 ++---\n builtin/am.c | 4 +-\n builtin/cat-file.c | 2 +-\n builtin/check-attr.c | 4 +-\n builtin/check-ignore.c | 4 +-\n builtin/checkout-index.c | 19 ++--\n builtin/checkout.c | 55 ++++++------\n builtin/clean.c | 6 +-\n builtin/clone.c | 4 +-\n builtin/commit.c | 20 ++---\n builtin/describe.c | 7 +-\n builtin/diff-files.c | 3 +-\n builtin/diff-index.c | 5 +-\n builtin/diff-tree.c | 4 +-\n builtin/difftool.c | 2 +-\n builtin/fsck.c | 16 ++--\n builtin/grep.c | 1 -\n builtin/log.c | 1 -\n builtin/merge-index.c | 16 ++--\n builtin/merge-ours.c | 3 +-\n builtin/merge-tree.c | 2 +-\n builtin/merge.c | 13 +--\n builtin/mv.c | 25 +++---\n builtin/pull.c | 6 +-\n builtin/read-tree.c | 6 +-\n builtin/rebase.c | 6 +-\n builtin/reset.c | 20 +++--\n builtin/rev-parse.c | 4 +-\n builtin/rm.c | 18 ++--\n builtin/stash.c | 8 +-\n builtin/submodule--helper.c | 14 +--\n builtin/update-index.c | 72 +++++++--------\n cache.h | 30 ++-----\n contrib/coccinelle/index-compatibility.cocci | 87 +++++++++++++++++++\n .../index-compatibility.pending.cocci | 78 +++++++++++++++++\n read-cache.c | 4 +-\n repository.c | 2 +-\n sequencer.c | 15 ++--\n t/helper/test-dump-cache-tree.c | 5 +-\n t/helper/test-dump-split-index.c | 1 +\n t/helper/test-dump-untracked-cache.c | 4 +-\n t/helper/test-fast-rebase.c | 4 +-\n t/helper/test-lazy-init-name-hash.c | 21 ++---\n t/helper/test-read-cache.c | 5 +-\n t/helper/test-scrap-cache-tree.c | 9 +-\n t/helper/test-write-cache.c | 6 +-\n 48 files changed, 417 insertions(+), 256 deletions(-)\n create mode 100644 contrib/coccinelle/index-compatibility.cocci\n create mode 100644 contrib/coccinelle/index-compatibility.pending.cocci\n\n-- \n2.38.0.1511.gcdcff1f1dc2\n\n"},{"id":"467496","messageId":"patch-01.12-760b4ddf06a-20221118T112205Z-avarab@gmail.com","threadId":"58812","inReplyTo":"cover-00.12-00000000000-20221118T112205Z-avarab@gmail.com","subject":"[PATCH 01/12] cache.h: remove unused \"the_index\" compat macros","fromName":"Ævar Arnfjörð Bjarmason","fromEmail":"avarab@gmail.com","sentAt":"2022-11-18T11:30:55Z","receivedAt":"2022-11-18T11:31:17Z","isPatch":true,"sender":{"key":"avarab@gmail.com","avatar":"https://avatars.githubusercontent.com/u/45301?v=4"},"body":"The \"active_alloc\" macro added in 228e94f9357 (Move index-related\nvariables into a structure., 2007-04-01) has not been used since\n4aab5b46f44 (Make read-cache.c \"the_index\" free., 2007-04-01).

As the name suggests this doesn't give us\nany of the compatibility macros, but only \"the_index\" variable.\n\nEventually we'll move other outstanding users of\n\"USE_THE_INDEX_COMPATIBILITY_MACROS\" over to using this more narrow\nand descriptive define.\n\nFor context: The USE_THE_INDEX_COMPATIBILITY_MACROS macro was added to\ntest-tool.h in f8adbec9fea (cache.h:

flip\nNO_THE_INDEX_COMPATIBILITY_MACROS switch, 2019-01-24).\n\nLet's move forward a bit by changing the users of those macros that\nare rare enough that we can convert them in one go, and then remove\nthe compatibility shim.\n\nThe only manual change to the C code here is to \"cache.h\", the rest is\nall the result of applying the new \"index-compatibility.cocci\".\n\nEven though it's a one-off, let's keep the coccinelle rules for\nnow.

In doing that we'll migrate rules from this\n\"index-compatibility.pending.cocci\" to the \"index-compatibility.cocci\"\ncreated in a preceding commit.\n\nSigned-off-by: Ævar Arnfjörð Bjarmason \n---\n .../index-compatibility.pending.cocci | 110 ++++++++++++++++++\n 1 file changed, 110 insertions(+)\n create mode 100644 contrib/coccinelle/index-compatibility.pending.cocci\n\ndiff --git a/contrib/coccinelle/index-compatibility.pending.cocci b/contrib/coccinelle/index-compatibility.pending.cocci\nnew file mode 100644\nindex 00000000000..6e96de0f638\n--- /dev/null\n+++ b/contrib/coccinelle/index-compatibility.pending.cocci\n@@ -0,0 +1,110 @@\n+// the_index.* variables\n+@@\n+@@\n+(\n+- active_cache\n++ the_index.cache\n+|\n+- active_nr\n++ the_index.cache_nr\n+|\n+- active_cache_changed\n++ the_index.cache_changed\n+|\n+- active_cache_tree\n++ the_index.cache_tree\n+)\n+\n+// \"the_repository\" simple cases\n+@@\n+@@\n+(\n+- read_cache\n++ repo_read_index\n+|\n+- hold_locked_index\n++ repo_hold_locked_index\n+)\n+ (\n++ the_repository,\n+ ...)\n+\n+// \"the_index\" simple cases\n+@@\n+@@\n+(\n+- discard_cache\n++ discard_index\n+|\n+- cache_name_pos\n++ index_name_pos\n+|\n+- add_cache_entry\n++ add_index_entry\n+|\n+- remove_file_from_cache\n++ remove_file_from_index\n+|\n+- ce_match_stat\n++ ie_match_stat\n+|\n+- ce_modified\n++ ie_modified\n+|\n+- resolve_undo_clear\n++ resolve_undo_clear_index\n+)\n+ (\n++ &the_index,\n+ ...)\n+\n+// \"the_repository\" special-cases\n+@@\n+@@\n+(\n+- read_cache_preload\n++ repo_read_index_preload\n+)\n+ (\n++ the_repository,\n+ ...\n++ , 0\n+ )\n+\n+@@\n+@@\n+(\n+- refresh_and_write_cache\n++ repo_refresh_and_write_index\n+)\n+ (\n++ the_repository,\n+ ...\n++ , NULL, NULL, NULL\n+ )\n+\n+\n+// \"the_index\" special-cases\n+@@\n+@@\n+(\n+- read_cache_from\n++ read_index_from\n+)\n+ (\n++ &the_index,\n+ ...\n++ , get_git_dir()\n+ )\n+\n+@@\n+@@\n+(\n+- refresh_cache\n++ refresh_index\n+)\n+ (\n++ &the_index,\n+ ...\n++ , NULL, NULL, NULL\n+ )\n-- \n2.38.0.1509.g9445af83948\n\n"},{"id":"467583","messageId":"patch-v2-06.11-6849233bf2b-20221119T125551Z-avarab@gmail.com","threadId":"58812","inReplyTo":"cover-v2-00.11-00000000000-20221119T125550Z-avarab@gmail.com","subject":"[PATCH v2 06/11] cocci & cache.h: apply a selection of \"pending\" index-compatibility","fromName":"Ævar Arnfjörð Bjarmason","fromEmail":"avarab@gmail.com","sentAt":"2022-11-19T13:07:33Z","receivedAt":"2022-11-19T13:08:03Z","isPatch":true,"sender":{"key":"avarab@gmail.com","avatar":"https://avatars.githubusercontent.com/u/45301?v=4"},"body":"Apply a selection of rules in \"index-compatibility.pending.cocci\"\ntree-wide, and in doing so migrate them to\n\"index-compatibility.cocci\".\n\nAs in preceding commits the only manual changes here are the macro\nremovals in \"cache.h\", and the update to the '*.cocci\" rules.

apply the part of \"index-compatibility.pending.cocci\" that\nrenames the global variables like \"active_nr\", which are a shorthand\nto referencing (in that case) a struct member as \"the_index.cache_nr\".\n\nIn doing so move more of \"index-compatibility.pending.cocci\" to\n\"index-compatibility.cocci\".\n\nIn the case of \"active_nr\" we'd have a textual conflict with\n\"ab/various-leak-fixes\" in \"next\"[1]. Let's exclude that specific case\nwhile moving the rule over from \"pending\".\n\n1. 407b94280f8 (commit: discard partial cache before (re-)reading it,\n 2022-11-08)\n\nSigned-off-by: Ævar Arnfjörð Bjarmason \n---\n builtin/add.c | 8 ++--\n builtin/checkout-index.c | 10 ++--\n builtin/checkout.c | 46 +++++++++----------\n builtin/commit.c | 16 +++----\n builtin/fsck.c | 12 ++---\n builtin/merge-index.c | 10 ++--\n builtin/merge.c | 6 +--\n builtin/mv.c | 19 ++++----\n builtin/read-tree.c | 2 +-\n builtin/reset.c | 2 +-\n builtin/rm.c | 14 +++---\n builtin/stash.c | 8 ++--\n builtin/submodule--helper.c | 14 +++---\n builtin/update-index.c | 46 +++++++++----------\n cache.h | 3 --\n contrib/coccinelle/index-compatibility.cocci | 22 +++++++++\n .../index-compatibility.pending.cocci | 17 -------\n t/helper/test-dump-cache-tree.c | 2 +-\n t/helper/test-scrap-cache-tree.c | 4 +-\n 19 files changed, 132 insertions(+), 129 deletions(-)\n\ndiff --git a/builtin/add.c b/builtin/add.c\nindex 75be1d021ab..23f9f0e08bb 100644\n--- a/builtin/add.c\n+++ b/builtin/add.c\n@@ -42,8 +42,8 @@ static int chmod_pathspec(struct pathspec *pathspec, char flip, int show_only)\n {\n \tint i, ret = 0;\n \n-\tfor (i = 0;
