* mru: use double-linked list from list.hot/mru-on-listOlga Telezhnaya2017-10-011-3/+4
| | | | | | | | | | | | Simplify mru.[ch] and related code by reusing the double-linked list implementation from list.h instead of a custom one. This commit is an intermediate step. Our final goal is to get rid of mru.[ch] at all and inline all logic.

* pack: make packed_git_mru global a value instead of a pointerJonathan Nieder2017-09-141-7/+5
| | | | | | | | | | | | | | | | | | | | | The MRU cache that keeps track of recently used packs is represented using two global variables: struct mru packed_git_mru_storage; struct mru *packed_git_mru = &packed_git_mru_storage; Callers never assign to the packed_git_mru pointer, though, so we can simplify by eliminating it and using &packed_git_mru_storage (renamed to &packed_git_mru) directly. This variable is only used by the packfile subsystem, making this a relatively uninvasive change (and any new unadapted callers would trigger a compile error). Noticed while moving these globals to the object_store struct.

* pack: move clear_delta_base_cache(), packed_object_info(), unpack_entry()Jonathan Tan2017-08-231-0/+661
| | | | | | | | | | | | 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 static state variablesJonathan Tan2017-08-231-0/+14
| | | | | | | | | | | sha1_file.c declares some static variables that store packfile-related state. Move them to packfile.c.

* pack: move pack name-related functionsJonathan Tan2017-08-231-0/+23
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>
