From 764df57e82c337a70f55e320bf31acb50c6ffacd Mon Sep 17 00:00:00 2001 From: Ben Straub Date: Fri, 15 Jun 2012 13:14:43 -0700 Subject: [PATCH 001/218] Add git_clone and git_clone_bare. So far they only create a repo, setup the "origin" remote, and fetch. The API probably needs work as well; there's no way to get progress information at this point. Also uncovered a shortcoming; git_remote_download doesn't fetch over local transport. --- include/git2.h | 1 + include/git2/clone.h | 45 ++++++++++++++++ src/clone.c | 112 +++++++++++++++++++++++++++++++++++++++ tests-clar/clone/clone.c | 101 +++++++++++++++++++++++++++++++++++ 4 files changed, 259 insertions(+) create mode 100644 include/git2/clone.h create mode 100644 src/clone.c create mode 100644 tests-clar/clone/clone.c diff --git a/include/git2.h b/include/git2.h index f260cfacde4..cab517d9974 100644 --- a/include/git2.h +++ b/include/git2.h @@ -37,6 +37,7 @@ #include "git2/index.h" #include "git2/config.h" #include "git2/remote.h" +#include "git2/clone.h" #include "git2/refspec.h" #include "git2/net.h" diff --git a/include/git2/clone.h b/include/git2/clone.h new file mode 100644 index 00000000000..7936282fa86 --- /dev/null +++ b/include/git2/clone.h @@ -0,0 +1,45 @@ +/* + * Copyright (C) 2012 the libgit2 contributors + * + * This file is part of libgit2, distributed under the GNU GPL v2 with + * a Linking Exception.

Also, this adds a minor helper function `git_tree_entry_byoid` that searches a `git_tree` for an entry with the given OID. This isn't a fast function, but it's easier than writing the loop yourself as an external user of the library. --- include/git2/tree.h | 11 +++++++++++ src/tree.c | 34 ++++++++++++++++++++++++++-------- 2 files changed, 37 insertions(+), 8 deletions(-) diff --git a/include/git2/tree.h b/include/git2/tree.h index f12b15e2e97..5c42f395798 100644 --- a/include/git2/tree.h +++ b/include/git2/tree.h @@ -128,6 +128,17 @@ GIT_EXTERN(const git_tree_entry *) git_tree_entry_byname(git_tree *tree, const c */ GIT_EXTERN(const git_tree_entry *) git_tree_entry_byindex(git_tree *tree, unsigned int idx);

The rules are: * A callback terminates the loop by returning any non-zero value * Once the callback returns non-zero, it will not be called again (i.e. the loop stops all iteration regardless of state) * If the callback returns non-zero, the parent fn returns GIT_EUSER * Although the parent returns GIT_EUSER, no error will be set in the library and `giterr_last()` will return NULL if called. This commit makes those changes across the library and adds tests for most of the iteration APIs to make sure that they follow the above rules. --- include/git2/attr.h | 21 +++--- include/git2/branch.h | 4 +- include/git2/config.h | 4 +- include/git2/diff.h | 18 +++++ include/git2/errors.h | 1 + include/git2/notes.h | 16 +++-- include/git2/odb.h | 7 +- include/git2/refs.h | 5 +- include/git2/remote.h | 5 +- include/git2/status.h | 4 +- src/attr.c | 9 ++- src/config_file.c | 4 +- src/diff_output.c | 103 +++++++++++++++++------------ src/notes.c | 45 ++++++------- src/odb.c | 5 +- src/odb_loose.c | 14 ++-- src/odb_pack.c | 9 ++- src/pack.c | 11 +-- src/path.h | 1 + src/refs.c | 22 ++++-- src/status.c | 22 ++++-- src/transports/git.c | 6 +- src/transports/http.c | 6 +- src/transports/local.c | 4 +- tests-clar/attr/repo.c | 22 ++++++ tests-clar/config/read.c | 2 +- tests-clar/diff/index.c | 50 ++++++++++++++ tests-clar/notes/notes.c | 30 ++++++++- tests-clar/odb/foreach.c | 18 +++++ tests-clar/refs/branches/foreach.c | 25 +++++++ tests-clar/refs/foreachglob.c | 22 ++++++ tests-clar/status/worktree.c | 33 +++++++-- 32 files changed, 401 insertions(+), 147 deletions(-) diff --git a/include/git2/attr.h b/include/git2/attr.h index fad7183da34..73a625a7ed8 100644 --- a/include/git2/attr.h +++ b/include/git2/attr.h @@ -172,18 +172,17 @@ GIT_EXTERN(int) git_attr_get_many( * * @param repo The repository containing the path. * @param flags A combination of GIT_ATTR_CHECK... flags. - * @param path The path inside the repo to check attributes.

Thus we could have the memory-mapped window information thread-local and avoid any locking. This is not practical in a few environments, such as Apple's GCD which allocates threads arbitrarily or the .NET CLR, where the OS-level thread can change at any moment.

This also adds tests for much of the new functionality to the existing `repo/init.c` test suite. Also, this adds a bunch of new utility functions including a very general purpose `git_futils_mkdir` (with the ability to make paths and to chmod the paths post-creation) and a file tree copying function `git_futils_cp_r`. Also, this includes some new path functions that were useful to keep the code simple. --- include/git2/config.h | 12 + include/git2/repository.h | 47 ++- src/attr_file.c | 15 +- src/config.c | 25 ++ src/fileops.c | 338 ++++++++++++++---- src/fileops.h | 83 ++++- src/path.c | 46 ++- src/path.h | 14 + src/posix.h | 7 + src/repository.c | 222 ++++++++---- src/repository.h | 1 - src/unix/posix.h | 1 + src/win32/posix.h | 8 + tests-clar/core/copy.c | 123 +++++++ tests-clar/core/mkdir.c | 169 +++++++++ tests-clar/repo/init.c | 82 ++++- .../resources/template/branches/.gitignore | 2 + tests-clar/resources/template/description | 1 + .../template/hooks/applypatch-msg.sample | 15 + .../template/hooks/commit-msg.sample | 24 ++ .../template/hooks/post-commit.sample | 8 + .../template/hooks/post-receive.sample | 15 + .../template/hooks/post-update.sample | 8 + .../template/hooks/pre-applypatch.sample | 14 + .../template/hooks/pre-commit.sample | 46 +++ .../template/hooks/pre-rebase.sample | 169 +++++++++ .../template/hooks/prepare-commit-msg.sample | 36 ++ .../resources/template/hooks/update.sample | 128 +++++++ tests-clar/resources/template/info/exclude | 6 + 29 files changed, 1481 insertions(+), 184 deletions(-) create mode 100644 tests-clar/core/copy.c create mode 100644 tests-clar/core/mkdir.c create mode 100644 tests-clar/resources/template/branches/.gitignore create mode 100644 tests-clar/resources/template/description create mode 100755 tests-clar/resources/template/hooks/applypatch-msg.sample create mode 100755 tests-clar/resources/template/hooks/commit-msg.sample create mode 100755 tests-clar/resources/template/hooks/post-commit.sample create mode 100755 tests-clar/resources/template/hooks/post-receive.sample create mode 100755 tests-clar/resources/template/hooks/post-update.sample create mode 100755 tests-clar/resources/template/hooks/pre-applypatch.sample create mode 100755 tests-clar/resources/template/hooks/pre-commit.sample create mode 100755 tests-clar/resources/template/hooks/pre-rebase.sample create mode 100755 tests-clar/resources/template/hooks/prepare-commit-msg.sample create mode 100755 tests-clar/resources/template/hooks/update.sample create mode 100644 tests-clar/resources/template/info/exclude diff --git a/include/git2/config.h b/include/git2/config.h index f415fbd9d8b..58a23833b0f 100644 --- a/include/git2/config.h +++ b/include/git2/config.h @@ -90,6 +90,18 @@ GIT_EXTERN(int) git_config_find_system(char *system_config_path, size_t length); */ GIT_EXTERN(int) git_config_open_global(git_config **out); +/** + * Open the global and system configuration files + * + * Utility wrapper that finds the global and system configuration files + * and opens them into a single prioritized config object that can be + * used when accessing config data outside a repository. + * + * @param out Pointer to store the config instance + * @return 0 or an error code + */ +GIT_EXTERN(int) git_config_open_outside_repo(git_config **out); + /** * Create a configuration file backend for ondisk files * diff --git a/include/git2/repository.h b/include/git2/repository.h index afef612c8a4..a986859d4a3 100644 --- a/include/git2/repository.h +++ b/include/git2/repository.h @@ -89,8 +89,11 @@ GIT_EXTERN(int) git_repository_discover( * * GIT_REPOSITORY_OPEN_NO_SEARCH - Only open the repository if it can be * immediately found in the start_path.

It also fixes a number of bugs that I found in other parts of the submodule API while writing the tests for the status part. This also fixes a couple of bugs in the iterators that had not been noticed before - one with iterating when there is a gitlink (i.e. separate-work-dir) and one where I was treating anything even vaguely submodule-like as a submodule, more aggressively than core git does. --- include/git2/diff.h | 15 ++ include/git2/oid.h | 2 + include/git2/submodule.h | 177 ++++++++-------- src/diff_output.c | 19 ++ src/iterator.c | 21 +- src/repository.c | 9 +- src/submodule.c | 367 ++++++++++++++++----------------- src/submodule.h | 18 +- tests-clar/status/submodules.c | 8 +- tests-clar/submodule/status.c | 286 ++++++++++++++++++++++++- 10 files changed, 606 insertions(+), 316 deletions(-) diff --git a/include/git2/diff.h b/include/git2/diff.h index 79ef7a49bb1..088e1ecfa94 100644 --- a/include/git2/diff.h +++ b/include/git2/diff.h @@ -391,6 +391,21 @@ GIT_EXTERN(int) git_diff_print_patch( void *cb_data, git_diff_data_fn print_cb); +/** + * Query how many diff records are there in a diff list. + * + * You can optionally pass in a `git_delta_t` value if you want a count + * of just entries that match that delta type, or pass -1 for all delta + * records. + * + * @param diff A git_diff_list generated by one of the above functions + * @param delta_t A git_delta_t value to filter the count, or -1 for all records + * @return Count of number of deltas matching delta_t type + */ +GIT_EXTERN(int) git_diff_entrycount( + git_diff_list *diff, + int delta_t); + /**@}*/ diff --git a/include/git2/oid.h b/include/git2/oid.h index 887b33e50d4..9e54a9f963e 100644 --- a/include/git2/oid.h +++ b/include/git2/oid.h @@ -185,6 +185,8 @@ GIT_EXTERN(int) git_oid_streq(const git_oid *a, const char *str); /** * Check is an oid is all zeros. + * + * @return 1 if all zeros, 0 otherwise. */ GIT_EXTERN(int) git_oid_iszero(const git_oid *a); diff --git a/include/git2/submodule.h b/include/git2/submodule.h index 6cd66465ee8..fe7f26cfe98 100644 --- a/include/git2/submodule.h +++ b/include/git2/submodule.h @@ -60,84 +60,68 @@ typedef enum { GIT_SUBMODULE_IGNORE_ALL = 3 /* never dirty */ } git_submodule_ignore_t; -/** - * Status values for submodules. - * - * One of these values will be returned for the submodule in the index - * relative to the HEAD tree, and one will be returned for the submodule in - * the working directory relative to the index.

This also adds a cap on the maximum size of data that will be loaded to diff. I set it at 512Mb which should match core git.

When this happens, the object is loaded and then disposed of immediately, which makes it difficult to efficiently use the header information to decide if the object should be loaded (since attempting to do so will often result in loading the object twice). This commit takes the existing code and reorganizes it to have two new functions: - `git_odb__read_header_or_object` which acts just like the old read header function except that it returns the object, too, if it was forced to load the whole thing. It then becomes the callers responsibility to free the `git_odb_object`. - `git_object__from_odb_object` which was extracted from the old `git_object_lookup` and creates a subclass of `git_object` from an existing `git_odb_object` (separating the ODB lookup from the `git_object` creation). This allows you to use the first header reading function efficiently without instantiating the `git_odb_object` twice.
