* packfile: keep prepare_packed_git() privatesb/packfiles-in-repositoryNguyễn Thái Ngọc Duy2018-03-261-1/+0
| | | | | | | | | | | | | | The reason callers have to call this is to make sure either packed_git or packed_git_mru pointers are initialized since we don't do that by default. Sometimes it's hard to see this connection between where the function is called and where packed_git pointer is used (sometimes in separate functions). Keep this dependency internal because now all access to packed_git and packed_git_mru must go through get_xxx() wrappers.

* packfile: add repository argument to prepare_packed_gitStefan Beller2018-03-261-1/+2
| | | | | | | | | | | Add a repository argument to allow prepare_packed_git callers to be more specific about which repository to handle. See commit "sha1_file: add repository argument to link_alt_odb_entry" for an explanation of the #define trick.

* packfile: allow install_packed_git to handle arbitrary repositoriesStefan Beller2018-03-261-1/+1
| | | | | | | | | | | | | | | | This conversion was done without the #define trick used in the earlier series refactoring to have better repository access, because this function is easy to review, as it only has one caller and all lines but the first two are converted. We must not convert 'pack_open_fds' to be a repository specific variable, as it is used to monitor resource usage of the machine that Git executes on.

* object-store: move packed_git and packed_git_mru to object storeStefan Beller2018-03-261-0/+3
| | | | | | | | | | | | | | | | In a process with multiple repositories open, packfile accessors should be associated to a single repository and not shared globally. 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(). This allows us to lazily initialize these fields without caller doing that explicitly] Signed-off-by: Stefan Beller <sbeller@google.com> Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* fsck: introduce partialclone extensionJonathan Tan2017-12-051-0/+13
| | | | | | | | | | | | | | | | | Currently, Git does not support repos with very large numbers of objects or repos that wish to minimize manipulation of certain blobs (for example, because they are very large) very well, even if the user operates mostly on part of the repo, because Git is designed on the assumption that every referenced object is available somewhere in the repo storage. In such an arrangement, the full set of objects is usually available in remote storage, ready to be lazily downloaded. Teach fsck about the new state of affairs. In this commit, teach fsck that missing promisor objects referenced from the reflog are not an error case; in future commits, fsck will be taught about other cases.

| | | | | | | | | | | | Both sha1_file.c and packfile.c now need read_object(), so a copy of read_object() was created in packfile.c. This patch makes both mark_bad_packed_object() and has_packed_and_bad() global. Unlike most of the other patches in this series, these 2 functions need to remain global.

* pack: move pack name-related functionsJonathan Tan2017-08-231-0/+27
Currently, sha1_file.c and cache.h contain many functions, both related to and unrelated to packfiles. This makes both files very large and causes an unclear separation of concerns. Create a new file, packfile.c, to hold all packfile-related functions currently in sha1_file.c. It has a corresponding header packfile.h. In this commit, the pack name-related functions are moved. Subsequent commits will move the other functions. Signed-off-by: Jonathan Tan <jonathantanmy@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
