2018-03-26sha1_file: add repository argument to sha1_loose_object_infoLibravatar Stefan Beller1-4/+5
Add a repository argument to allow the sha1_loose_object_info caller to be more specific about which repository to act on. This is a small mechanical change; it doesn't change the implementation to handle repositories other than the_repository yet.

2018-03-26sha1_file: allow link_alt_odb_entries to handle arbitrary repositoriesLibravatar Stefan Beller2-20/+20
Actually this also allows read_info_alternates and link_alt_odb_entry to handle arbitrary repositories, but link_alt_odb_entries is the most interesting function in this set of functions, hence the commit subject. These functions span a strongly connected component in the function graph, i.e. the recursive call chain might look like -> link_alt_odb_entries -> link_alt_odb_entry -> read_info_alternates -> link_alt_odb_entries That is why we need to convert all these functions at the same time.

2018-03-26sha1_file: add repository argument to link_alt_odb_entryLibravatar Stefan Beller1-3/+5
Add a repository argument to allow the link_alt_odb_entry caller to be more specific about which repository to act on. This is a small mechanical change; it doesn't change the implementation to handle repositories other than the_repository yet. Since the implementation does not yet work with other repositories, use a wrapper macro to enforce that the caller passes in the_repository as the first argument. It would be more appealing to use BUILD_ASSERT_OR_ZERO to enforce this, but that doesn't work because it requires a compile-time constant and common compilers like gcc 4.8.4 do not consider "r == the_repository" a compile-time constant. This and the following three patches add repository arguments to link_alt_odb_entry, read_info_alternates, link_alt_odb_entries and prepare_alt_odb. Three out of the four functions are found in a recursive call chain, calling each other, and one of them accesses the repositories `objectdir` (which was migrated; it was an obvious choice) and `ignore_env` (which we need to keep in the repository struct for clarify); hence we will pass through the repository unlike just the object store object + the ignore_env flag.

2018-03-26pack: move approximate object count to object storeLibravatar Stefan Beller2-6/+13
The approximate_object_count() function maintains a rough count of objects in a repository to estimate how long object name abbreviates should be. Object names are scoped to a repository and the appropriate length may differ by repository, so the object count should not be global.

Move packed_git and packed_git_mru into the_repository and adjust callers to reflect this. [nd: while at there, wrap access to these two fields in get_packed_git() and get_packed_git_mru().

In a process with multiple repositories open, alternates should be associated to a single repository and not shared globally. Move alt_odb_list and alt_odb_tail into the_repository and adjust callers to reflect this. Now that the alternative object data base is per repository, we're leaking its memory upon freeing a repository. The next patch plugs this hole. No functional change intended.

2018-03-23repository: introduce raw object store fieldLibravatar Stefan Beller8-17/+56
The raw object store field will contain any objects needed for access to objects in a given repository. This patch introduces the raw object store and populates it with the `objectdir`, which used to be part of the repository struct. As the struct gains members, we'll also populate the function to clear the memory for these members. In a later step, we'll introduce a struct object_parser, that will complement the object parsing in a repository struct: The raw object parser is the layer that will provide access to raw object content, while the higher level object parser code will parse raw objects and keeps track of parenthood and other object relationships using 'struct object'. For now only add the lower level to the repository struct.

2018-03-05repository: delete ignore_env memberLibravatar Nguyễn Thái Ngọc Duy2-11/+0
This variable was added because the repo_set_gitdir() was created to cover both submodule and main repos, but these two are initialized a bit differently so ignore_env == 0 means main repo, while ignore_env != 0 is submodules. Since the difference part (env variables) has been moved out of repo_set_gitdir(), this function works the same way for both repo types and ignore_env is not needed anymore.

2018-03-05sha1_file.c: move delayed getenv(altdb) back to setup_git_env()Libravatar Nguyễn Thái Ngọc Duy4-5/+9
getenv() is supposed to work on the main repository only. This delayed getenv() code in sha1_file.c makes it more difficult to convert sha1_file.c to a generic object store that could be used by both submodule and main repositories.

2018-03-05repository.c: move env-related setup code back to environment.cLibravatar Nguyễn Thái Ngọc Duy5-25/+79
It does not make sense that generic repository code contains handling of environment variables, which are specific for the main repository only. Refactor repo_set_gitdir() function to take $GIT_DIR and optionally _all_ other customizable paths. These optional paths can be NULL and will be calculated according to the default directory layout. Note that some dead functions are left behind to reduce diff noise. They will be deleted in the next patch.
