2018-04-11Merge branch 'sb/object-store'Libravatar Junio C Hamano1-1/+4
Refactoring the internal global data structure to make it possible to open multiple repositories, work with and then close them. Rerolled by Duy on top of a separate preliminary clean-up topic. The resulting structure of the topics looked very sensible. * sb/object-store: (27 commits) sha1_file: allow sha1_loose_object_info to handle arbitrary repositories sha1_file: allow map_sha1_file to handle arbitrary repositories sha1_file: allow map_sha1_file_1 to handle arbitrary repositories sha1_file: allow open_sha1_file to handle arbitrary repositories sha1_file: allow stat_sha1_file to handle arbitrary repositories sha1_file: allow sha1_file_name to handle arbitrary repositories sha1_file: add repository argument to sha1_loose_object_info sha1_file: add repository argument to map_sha1_file sha1_file: add repository argument to map_sha1_file_1 sha1_file: add repository argument to open_sha1_file sha1_file: add repository argument to stat_sha1_file sha1_file: add repository argument to sha1_file_name sha1_file: allow prepare_alt_odb to handle arbitrary repositories sha1_file: allow link_alt_odb_entries to handle arbitrary repositories sha1_file: add repository argument to prepare_alt_odb sha1_file: add repository argument to link_alt_odb_entries sha1_file: add repository argument to read_info_alternates sha1_file: add repository argument to link_alt_odb_entry sha1_file: add raw_object_store argument to alt_odb_usable pack: move approximate object count to object store ...
2018-03-26packfile: keep prepare_packed_git() privateLibravatar Nguyễn Thái Ngọc Duy1-1/+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.

2018-03-26packfile: add repository argument to prepare_packed_gitLibravatar Stefan Beller1-1/+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.

2018-03-26packfile: allow install_packed_git to handle arbitrary repositoriesLibravatar Stefan Beller1-1/+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.

2018-03-26object-store: move packed_git and packed_git_mru to object storeLibravatar Stefan Beller1-0/+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>
2018-03-22packfile: define and use bsearch_pack()Libravatar Derrick Stolee1-0/+8
The method bsearch_hash() generalizes binary searches using a fanout table. The only consumer is currently find_pack_entry_one(). It requires a bit of pointer arithmetic to align the fanout table and the lookup table depending on the pack-index version. Extract the pack-index pointer arithmetic to a new method, bsearch_pack(), so this can be re-used in other code paths.

2017-12-05fsck: introduce partialclone extensionLibravatar Jonathan Tan1-0/+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. Signed-off-by: Jonathan Tan <jonathantanmy@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2017-08-23pack: move pack name-related functionsLibravatar Jonathan Tan1-0/+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>
