2018-05-02sha1-file: add functions for hex empty tree and blob OIDsLibravatar brian m. carlson1-0/+12
Oftentimes, we'll want to refer to an empty tree or empty blob by its hex name without having to call oid_to_hex or explicitly refer to the_hash_algo. Add helper functions that format these values into static buffers and return them for easy use.

A "git fetch" from a repository with insane number of refs into a repository that is already up-to-date still wasted too many cycles making many lstat(2) calls to see if these objects at the tips exist as loose objects locally. These lstat(2) calls are optimized away by enumerating all loose objects beforehand. It is unknown if the new strategy negatively affects existing use cases, fetching into a repository with many loose objects from a repository with small number of refs. * ti/fetch-everything-local-optim: fetch-pack.c: use oidset to check existence of loose object

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.

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.

2018-03-23repository: introduce raw object store fieldLibravatar Stefan Beller1-1/+3
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.

2018-03-14fetch-pack.c: use oidset to check existence of loose objectLibravatar Takuto Ikuta1-0/+3
When fetching from a repository with large number of refs, because to check existence of each refs in local repository to packed and loose objects, 'git fetch' ends up doing a lot of lstat(2) to non-existing loose form, which makes it slow. Instead of making as many lstat(2) calls as the refs the remote side advertised to see if these objects exist in the loose form, first enumerate all the existing loose objects in hashmap beforehand and use it to check existence of them if the number of refs is larger than the number of loose objects. With this patch, the number of lstat(2) calls in `git fetch` is reduced from 411412 to 13794 for chromium repository, it has more than 480000 remote refs. I took time stat of `git fetch` when fetch-pack happens for chromium repository 3 times on linux with SSD. * with this patch 8.105s 8.309s 7.640s avg: 8.018s * master 12.287s 11.175s 12.227s avg: 11.896s On my MacBook Air which has slower lstat(2). * with this patch 14.501s * master 1m16.027s `git fetch` on slow disk will be improved largely.

2018-03-14sha1_file: introduce a constant for max header lengthLibravatar brian m. carlson1-7/+10
There were several instances of 32 sprinkled throughout this file, all of which were used for allocating a buffer to store the header of an object. Introduce a constant, MAX_HEADER_LEN, for this purpose. Note that this constant is slightly larger than required; the longest possible header is 28 (7 for "commit", 1 for a space, 20 for a 63-bit length in decimal, and 1 for the NUL).

2018-03-13sha1_file: restore OBJECT_INFO_QUICK functionalityLibravatar Jonathan Tan1-3/+5
Support for the OBJECT_INFO_QUICK flag in sha1_object_info_extended() was added in commit dfdd4afcf9 ("sha1_file: teach sha1_object_info_extended more flags", 2017-06-26) in order to support commit e83e71c5e1 ("sha1_file: refactor has_sha1_file_with_flags", 2017-06-26), but it was inadvertently removed in commit 8b4c0103a9 ("sha1_file: support lazily fetching missing objects", 2017-12-08). Restore this functionality. Signed-off-by: Jonathan Tan <jonathantanmy@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Avoid using identifiers that clash with C++ keywords. Even though it is not a goal to compile Git with C++ compilers, changes like this help use of code analysis tools that targets C++ on our codebase. * bw/c-plus-plus: (37 commits) replace: rename 'new' variables trailer: rename 'template' variables tempfile: rename 'template' variables wrapper: rename 'template' variables environment: rename 'namespace' variables diff: rename 'template' variables environment: rename 'template' variables init-db: rename 'template' variables unpack-trees: rename 'new' variables trailer: rename 'new' variables submodule: rename 'new' variables split-index: rename 'new' variables remote: rename 'new' variables ref-filter: rename 'new' variables read-cache: rename 'new' variables line-log: rename 'new' variables imap-send: rename 'new' variables http: rename 'new' variables entry: rename 'new' variables diffcore-delta: rename 'new' variables ...
2018-03-05sha1_file.c: move delayed getenv(altdb) back to setup_git_env()Libravatar Nguyễn Thái Ngọc Duy1-5/+1
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. Move the getenv() back in setup_git_env() where other env vars are also fetched. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
