But that's in\nsb/object-store, so.. I'm rerolling all three\n\n01/44 - 05/44: nd/remove-ignore-env-field\n\n This series is moved up top. After this the patch that touch\n alternate-db in sha1_file.c looks natural because no env is involved\n anymore\n\n I also take this opportunity to introduce a new patch 01/44 to avoid\n struct initialization that makes it hard to read and update. Later\n patches are also simplified thanks to this.\n\n06/44 - 32/44: sb/object-store\n\n 06/44 is updated to introduce raw_object_store_init() instead of\n RAW_OBJECT_STORE_INIT macro. This function is now used to initialize\n both main repo and submodule ones.\n\n 10/44 (moving \"packed_git\") also introduces two new access wrapper\n get_packed_git() and get_packed_git_mru()\n\n33/44 - 44/44: sb/packfiles-in-repository\n\n The only thing new here is 44/44 which makes prepare_packed_git()\n internal. get_packed_git() and get_packed_git_mru() introduced\n earlier will call prepare_packed_git() automatically.\n\nThe whole thing is also available at\n\nhttps://github.com/pclouds/git/tree/ignore-env-object-store-packfiles\n\nAnd interdiff of all three, compared to what is currently in 'pu'.\nLooks pretty good in my opinon:\n\ndiff --git a/builtin/count-objects.c b/builtin/count-objects.c\nindex d480301763..ee6ae35244 100644\n--- a/builtin/count-objects.c\n+++ b/builtin/count-objects.c\n@@ -121,9 +121,8 @@ int cmd_count_objects(int argc, const char **argv, const char *prefix)\n \t\tstruct strbuf loose_buf = STRBUF_INIT;\n \t\tstruct strbuf pack_buf = STRBUF_INIT;\n \t\tstruct strbuf garbage_buf = STRBUF_INIT;\n-\t\tif (!the_repository->objects.packed_git)\n-\t\t\tprepare_packed_git(the_repository);\n-\t\tfor (p = the_repository->objects.packed_git;

Stefan Beller \n\nThe raw object store field will contain any objects needed for\naccess to objects in a given repository.\n\nThis patch introduces the raw object store and populates it with the\n`objectdir`, which used to be part of the repository struct.\n\nAs the struct gains members, we'll also populate the function to clear\nthe memory for these members.\n\nIn a later we'll introduce a struct object_parser, that will complement\nthe object parsing in a repository struct: The raw object parser is the\nlayer that will provide access to raw object content, while the higher\nlevel object parser code will parse raw objects and keeps track of\nparenthood and other object relationships using 'struct object'.\nFor now only add the lower level to the repository

This is a small\nmechanical change; it doesn't change the implementation to handle\nrepositories other than the_repository yet.\n\nSince the implementation does not yet work with other repositories,\nuse a wrapper macro to enforce that the caller passes in\nthe_repository as the first argument. It would be more appealing to\nuse BUILD_ASSERT_OR_ZERO to enforce this, but that doesn't work\nbecause it requires a compile-time constant and common compilers like\ngcc 4.8.4 do not consider \"r == the_repository\" a compile-time\nconstant.\n\nThis and the following three patches add repository arguments to\nlink_alt_odb_entry, read_info_alternates, link_alt_odb_entries\nand prepare_alt_odb. Three out of the four functions are found\nin a recursive call chain, calling each other, and one of them\naccesses the repositories `objectdir` (which was migrated; it\nwas an obvious choice) and `ignore_env` (which we need to keep in\nthe repository struct for clarify); hence we will pass through the\nrepository unlike just the object store object + the ignore_env flag.\n\nSigned-off-by:

You're marking packed_git\nas \"private\"...well C has no notion of private vs public fields in a\nstruct so it might be difficult to keep that convention, it also took me\na second to realize that it was only in the scope of packfile.c where it\nwas ok to reference it directly. Maybe it'll be ok? If we really\nwanted something to be private we'd need it to be an opaque type\ninstead, which may be out of the scope of this code refactor.\n\n> \n> 3. Applying line wrapping fixes from \"make style\" to break the\n> resulting long lines.\n> \n> 4. Adding missing #includes of repository.h where needed.\n> \n> 5. As the packfiles are now owned by an objectstore, which is ephemeral\n> unlike globals, we introduce memory leaks. So address them in\n> raw_object_store_clear(). Defer freeing packed_git to the next\n> patch due to the size of this patch.\n> \n> Signed-off-by: Stefan Beller \n> Signed-off-by: Jonathan Nieder \n> Signed-off-by: Nguyễn Thái Ngọc Duy \n> ---\n> builtin/count-objects.c | 5 ++--\n> builtin/fsck.c | 6 +++--\n> builtin/gc.c | 3 ++-\n> builtin/pack-objects.c | 20 ++++++++--------\n> builtin/pack-redundant.c | 5 ++--\n> cache.h | 29 ------------------------\n> fast-import.c | 7 ++++--\n> http-backend.c | 5 ++--\n> object-store.h | 28 +++++++++++++++++++++++\n> object.c | 7 ++++++\n> pack-bitmap.c | 3 ++-\n> packfile.c | 49 ++++++++++++++++++++++++----------------\n> packfile.h | 3 +++\n> server-info.c | 5 ++--\n> sha1_name.c | 5 ++--\n> 15 files changed, 107 insertions(+), 73 deletions(-)\n> \n> diff --git a/builtin/count-objects.c b/builtin/count-objects.c\n> index 33343818c8..5c7c3c6ae3 100644\n> --- a/builtin/count-objects.c\n> +++ b/builtin/count-objects.c\n> @@ -7,6 +7,7 @@\n> #include \"cache.h\"\n> #include \"config.h\"\n> #include \"dir.h\"\n> +#include \"repository.h\"\n> #include \"builtin.h\"\n> #include \"parse-options.h\"\n> #include \"quote.h\"\n> @@ -120,9 +121,9 @@ int cmd_count_objects(int argc, const char **argv, const char *prefix)\n> \t\tstruct strbuf loose_buf = STRBUF_INIT;\n> \t\tstruct strbuf pack_buf = STRBUF_INIT;\n> \t\tstruct strbuf garbage_buf = STRBUF_INIT;\n> -\t\tif (!packed_git)\n> +\t\tif (!get_packed_git(the_repository))\n> \t\t\tprepare_packed_git();\n> -\t\tfor (p = packed_git;

I saw your other comment about the not converting in packfile.c\ntoo. My view is, packfile has intimate knowledge about pack\nmanipulation and we don't need to try to \"protect\" from misuse of\npacked_git pointer without prepare_packed_git.

I plan to resolve this with an evil merge\nto include object-store.h from pack-objects.h to resolve this with\nminimum damage to topics in flight.\n\n\n"},{"id":"343063","messageId":"CAGZ79ka0ptbwHU0Ym7aGm86o+YG27goHR6iS3uf5yUkj0Uj15w@mail.gmail.com","threadId":"47963","inReplyTo":"20180323155523.22269-2-pclouds@gmail.com","subject":"Re: [PATCH 1/1] repository.h: add comment and clarify repo_set_gitdir","fromName":"Stefan Beller","fromEmail":"sbeller@google.com","sentAt":"2018-03-26T21:04:33Z","receivedAt":"2018-03-26T21:04:48Z","isPatch":true,"sender":{"key":"stefanbeller@gmail.com","avatar":"https://avatars.githubusercontent.com/u/455868?v=4"},"body":"On Fri, Mar 23, 2018 at 8:55 AM Nguyễn Thái Ngọc Duy \nwrote:\n\n> The argument name \"optional\" may mislead the reader to think this\n> option could be NULL.
