50e01216	2021-03-20T16:39:29	repo: introduce git_repository_workdir_path Add a simple accessor for workdir paths to get an absolute on-disk path given a repository and a relative path within it. This is useful to avoid copy-pasta `git_buf_joinpath` and to ensure that we validate working directory paths while honoring `core.longpaths` settings.
dc1ba018	2021-03-20T13:01:00	path: introduce ondisk and workdir path validation Introduce `git_path_validate_filesystem` which validates (absolute) on-disk paths and `git_path_validate_workdir` to perform validations on (absolute) working directory paths. These functions are useful as there may be system limitations on on-disk paths, particularly on Windows (for example, enforcing MAX_PATH). For working directory paths, these limitations may be per-repository, based on the `core.longpaths` configuration setting.
f52f593e	2020-12-20T16:33:42	repository: use intptr_t's in the config map cache Since we're using atomic primitives to read and write into the config map cache, we need to read/write something pointer-sized. Use an `intptr_t` for the config map cache.
37763d38	2020-12-05T15:26:59	threads: rename git_atomic to git_atomic32 Clarify the `git_atomic` type and functions now that we have a 64 bit version as well (`git_atomic64`).
4cc3b2cb	2020-07-13T10:08:23	repo: add git_repository_initialbranch Provide a helper function to get the initial branch for a repository, respecting the `init.defaultBranch` configuration option, if set, and returning the "default default" (currently `master`) otherwise.
d1f210fc	2020-06-17T15:09:49	repository: remove function to iterate over HEADs The function `git_repository_foreach_head` is broken, as it directly interacts with the on-disk representation of the reference database, thus assuming that no other refdb is used for the given repository. As this is an internal function only and all users have been replaced, let's remove this function.
2fcb4f28	2020-06-17T14:09:04	repository: introduce new function to iterate over all worktrees Given a Git repository, it's non-trivial to iterate over all worktrees that are associated with it, including the "main" repository. This commit adds a new internal function `git_repository_foreach_worktree` that does this for us.

658022c4	2019-07-18T13:53:41	configuration: cvar -> configmap `cvar` is an unhelpful name. Refactor its usage to `configmap` for more clarity.
efb20825	2019-02-14T13:05:49	branches: introduce flag to skip enumeration of certain HEADs Right now, the function `git_repository_foreach_head` will always iterate over all HEADs of the main repository and its worktrees. In some cases, it might be required to skip either of those, though. Add a flag in preparation for the following commit that enables this behaviour.
f673e232	2018-12-27T13:47:34	git_error: use new names in internal APIs and usage Move to the `git_error` name in the internal API for error-related functions.
e226ad8f	2018-11-17T17:55:10	refs: add support for core.logAllRefUpdates=always Since we were not expecting this config entry to contain a string, we would fail as soon as its (cached) value would be accessed. Hence, provide some constants for the 4 states we use, and account for "always" when we decide to reflog changes.
0c7f49dd	2017-06-30T13:39:01	Make sure to always include "common.h" first Next to including several files, our "common.h" header also declares various macros which are then used throughout the project. As such, we have to make sure to always include this file first in all implementation files. Otherwise, we might encounter problems or even silent behavioural differences due to macros or defines not being defined as they should be. So in fact, our header and implementation files should make sure to always include "common.h" first. This commit does so by establishing a common include pattern. Header files inside of "src" will now always include "common.h" as its first other file, separated by a newline from all the other includes to make it stand out as special. There are two cases for the implementation files. If they do have a matching header file, they will always include this one first, leading to "common.h" being transitively included as first file. If they do not have a matching header file, they instead include "common.h" as first file themselves. This fixes the outlined problems and will become our standard practice for header and source files inside of the "src/" from now on.
6c23704d	2017-06-08T21:40:18	settings: rename `GIT_OPT_ENABLE_SYNCHRONOUS_OBJECT_CREATION` Initially, the setting has been solely used to enable the use of `fsync()` when creating objects. Since then, the use has been extended to also cover references and index files. As the option is not yet part of any release, we can still correct this by renaming the option to something more sensible, indicating not only correlation to objects. This commit renames the option to `GIT_OPT_ENABLE_FSYNC_GITDIR`. We also move the variable from the object to repository source code.
74511aa2	2017-04-04T18:44:29	repository: add function to iterate over all HEADs While we already provide functions to get the current repository's HEAD, it is quite involved to iterate over HEADs of both the repository and all linked work trees. This commit implements a function `git_repository_foreach_head`, which accepts a callback which is then called for all HEAD files.
1c04a96b	2017-02-28T12:29:29	Honor `core.fsyncObjectFiles`
84f56cb0	2016-11-04T11:59:52	repository: rename `path_repository` and `path_gitlink` The `path_repository` variable is actually confusing to think about, as it is not always clear what the repository actually is. It may either be the path to the folder containing worktree and .git directory, the path to .git itself, a worktree or something entirely different. Actually, the intent of the variable is to hold the path to the gitdir, which is either the .git directory or the bare repository. Rename the variable to `gitdir` to avoid confusion. While at it, also rename `path_gitlink` to `gitlink` to improve consistency.
854b5c70	2015-10-26T16:21:09	repository: expose `repo_init_create_head` Expose the function `repo_init_create_head` as `git_repository_create_head`.
79ab3ef6	2015-10-15T15:58:05	repository: introduce is_worktree variable
c09fd54e	2015-09-16T12:10:11	repository: introduce commondir variable The commondir variable stores the path to the common directory. The common directory is used to store objects and references shared across multiple repositories. A current use case is the newly introduced `git worktree` feature, which sets up a separate working copy, where the backing git object store and references are pointed to by the common directory.
4d99c4cf	2016-11-23T18:32:48	Allow for caching of submodules. Added `git_repository_submodule_cache_all` to initialze a cache of submodules on the repository so that operations looking up N submodules are O(N) and not O(N^2). Added a `git_repository_submodule_cache_clear` function to remove the cache. Also optimized the function that loads all submodules as it was itself O(N^2) w.r.t the number of submodules, having to loop through the `.gitmodules` file once per submodule. I changed it to process the `.gitmodules` file once, into a map. Signed-off-by: David Turner <dturner@twosigma.com>

dfda2f68	2015-04-27T19:27:29	submodule: remove the per-repo cache Having this cache and giving them out goes against our multithreading guarantees and it makes it impossible to use submodules in a multi-threaded environment, as any thread can ask for a refresh which may reallocate some string in the submodule struct which we've accessed in a different one via a getter. This makes the submodules behave more like remotes, where each object is created upon request and not shared except explicitly by the user. This means that some tests won't pass yet, as they assume they can affect the submodule objects in the cache and that will affect later operations.

659cf202	2015-01-07T12:23:05	Remove the signature from ref-modifying functions The signature for the reflog is not something which changes dynamically. Almost all uses will be NULL, since we want for the repository's default identity to be used, making it noise. In order to allow for changing the identity, we instead provide git_repository_set_ident() and git_repository_ident() which allow a user to override the choice of signature.
4196dd8e	2015-02-26T15:33:58	repository: Introduce "reserved names" A repository can have multiple "reserved names" now, not just a single "short name" for the repository folder itself. Refactor to include a git_repository__reserved_names that returns all the reserved names for a repository.
9f779aac	2015-01-29T14:40:55	attrcache: don't re-read attrs during checkout During checkout, assume that the .gitattributes files aren't modified during the checkout. Instead, create an "attribute session" during checkout. Assume that attribute data read in the same checkout "session" hasn't been modified since the checkout started. (But allow subsequent checkouts to invalidate the cache.) Further, cache nonexistent git_attr_file data even when .gitattributes files are not found to prevent re-scanning for nonexistent files.
ec74b40c	2014-12-16T18:53:55	Introduce core.protectHFS and core.protectNTFS Validate HFS ignored char ".git" paths when `core.protectHFS` is specified. Validate NTFS invalid ".git" paths when `core.protectNTFS` is specified.
a64119e3	2014-11-25T18:13:00	checkout: disallow bad paths on win32 Disallow: 1. paths with trailing dot 2. paths with trailing space 3. paths with trailing colon 4. paths that are 8.3 short names of .git folders ("GIT~1") 5. paths that are reserved path names (COM1, LPT1, etc). 6. paths with reserved DOS characters (colons, asterisks, etc) These paths would (without \\?\ syntax) be elided to other paths - for example, ".git." would be written as ".git". As a result, writing these paths literally (using \\?\ syntax) makes them hard to operate with from the shell, Windows Explorer or other tools. Disallow these.

40ed4990	2014-02-11T14:45:37	Add diff threading tests and attr file cache locks This adds a basic test of doing simultaneous diffs on multiple threads and adds basic locking for the attr file cache because that was the immediate problem that arose from these tests.

69b6ffc4	2014-03-28T14:02:21	Make a real submodule cache object This takes the old submodule cache which was just a git_strmap and makes a real git_submodule_cache object that can contain other things like a lock and timestamp-ish data to control refreshing of submodule info.

2fe54afa	2013-09-30T16:58:33	Put hooks in place for precompose in dirload fn This doesn't actual do string precompose but it puts the hooks in place into the iterators and the git_path_dirload function so that the actual precompose work is ready to go.
114f5a6c	2013-06-10T10:10:39	Reorganize diff and add basic diff driver This is a significant reorganization of the diff code to break it into a set of more clearly distinct files and to document the new organization. Hopefully this will make the diff code easier to understand and to extend. This adds a new `git_diff_driver` object that looks of diff driver information from the attributes and the config so that things like function content in diff headers can be provided. The full driver spec is not implemented in the commit - this is focused on the reorganization of the code and putting the driver hooks in place. This also removes a few #includes from src/repository.h that were overbroad, but as a result required extra #includes in a variety of places since including src/repository.h no longer results in pulling in the whole world.

ab01cbd4	2013-04-22T14:24:12	Add configs to repo config cache This adds a bunch of additional config values to the repository config value cache and makes it easier to add a simple boolean config without creating enum values for each possible setting. Also, this fixes a bug in git_config_refresh where the config cache was not being cleared which could lead to potential incorrect values. The work to start using the new cached configs will come in the next couple of commits...
e976b56d	2013-04-15T14:27:53	Add git__compare_and_swap and use it This removes the lock from the repository object and changes the internals to use the new atomic git__compare_and_swap to update the _odb, _config, _index, and _refdb variables in a threadsafe manner.
53607868	2013-04-15T00:09:03	Further threading fixes This builds on the earlier thread safety work to make it so that setting the odb, index, refdb, or config for a repository is done in a threadsafe manner with minimized locking time. This is done by adding a lock to the repository object and using it to guard the assignment of the above listed pointers. The lock is only held to assign the pointer value. This also contains some minor fixes to the other work with pack files to reduce the time that locks are being held to and fix an apparently memory leak.
5540d947	2013-03-15T16:39:00	Implement global/system file search paths The goal of this work is to expose the search logic for "global", "system", and "xdg" files through the git_libgit2_opts() interface. Behind the scenes, I changed the logic for finding files to have a notion of a git_strarray that represents a search path and to store a separate search path for each of the three tiers of config file. For each tier, I implemented a function to initialize it to default values (generally based on environment variables), and then general interfaces to get it, set it, reset it, and prepend new directories to it. Next, I exposed these interfaces through the git_libgit2_opts interface, reusing the GIT_CONFIG_LEVEL_SYSTEM, etc., constants for the user to control which search path they were modifying. There are alternative designs for the opts interface / argument ordering, so I'm putting this phase out for discussion. Additionally, I ended up doing a little bit of clean up regarding attr.h and attr_file.h, adding a new attrcache.h so the other two files wouldn't have to be included in so many places.

c6ac28fd	2012-09-10T12:24:05	Reorg internal odb read header and object lookup Often `git_odb_read_header` will "fail" and have to read the entire object into memory instead of just the header. 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. There is no net change to the behavior of any of the existing functions, but this allows internal code to tap into the ODB lookup and object creation to be more efficient.

ca1b6e54	2012-07-31T17:02:54	Add template dir and set gid to repo init This extends git_repository_init_ext further with support for initializing the repository from an external template directory and with support for the "create shared" type flags that make a set GID repository directory. 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.
662880ca	2012-07-26T16:07:01	Add git_repository_init_ext for power initters The extended version of repository init adds support for many of the things that you can do with `git init` and sets up structures that will make it easier to extend further in the future.

f917481e	2012-05-03T16:37:25	Support reading attributes from index Depending on the operation, we need to consider gitattributes in both the work dir and the index. This adds a parameter to all of the gitattributes related functions that allows user control of attribute reading behavior (i.e. prefer workdir, prefer index, only use index). This fix also covers allowing us to check attributes (and hence do diff and status) on bare repositories. This was a somewhat larger change that I hoped because it had to change the cache key used for gitattributes files.
c2b67043	2012-04-25T15:20:28	Rename git_khash_str to git_strmap, etc. This renamed `git_khash_str` to `git_strmap`, `git_hash_oid` to `git_oidmap`, and deletes `git_hashtable` from the tree, plus adds unit tests for `git_strmap`.
01fed0a8	2012-04-25T10:36:01	Convert hashtable usage over to khash This updates khash.h with some extra features (like error checking on allocations, ability to use wrapped malloc, foreach calls, etc), creates two high-level wrappers around khash: `git_khash_str` and `git_khash_oid` for string-to-void-ptr and oid-to-void-ptr tables, then converts all of the old usage of `git_hashtable` over to use these new hashtables. For `git_khash_str`, I've tried to create a set of macros that yield an API not too unlike the old `git_hashtable` API. Since the oid hashtable is only used in one file, I haven't bother to set up all those macros and just use the khash APIs directly for now.
95dfb031	2012-03-30T14:40:50	Improve config handling for diff,submodules,attrs This adds support for a bunch of core.* settings that affect diff and status, plus fixes up some incorrect implementations of those settings from before. Also, this cleans up the handling of config settings in the new submodules code and in the old attrs/ignore code.
bfc9ca59	2012-03-28T16:45:36	Added submodule API and use in status When processing status for a newly checked out repo, it is possible that there will be submodules that have not yet been initialized. The only way to distinguish these from untracked directories is to have some knowledge of submodules. This commit adds a new submodule API which, given a name or path, can determine if it appears to be a submodule and can give information about the submodule.

This includes refactoring the gitattributes code to share logic where possible. The GIT_STATUS_IGNORED flag will now be passed in for files that are ignored (provided they are not already in the index or the head of repo).
73b51450	2011-12-28T23:28:50	Add support for macros and cache flush API. Add support for git attribute macro definitions. Also, add support for cache flush API to clear the attribute file content cache when needed. Additionally, improved the handling of global and system files, making common utility functions in fileops and converting config and attr to both use the common functions. Adds a bunch more tests and fixed some memory leaks. Note that adding macros required me to use refcounted attribute assignment definitions, which complicated, but probably improved memory usage.
ee1f0b1a	2011-12-16T10:56:43	Add APIs for git attributes This adds APIs for querying git attributes. In addition to the new API in include/git2/attr.h, most of the action is in src/attr_file.[hc] which contains utilities for dealing with a single attributes file, and src/attr.[hc] which contains the implementation of the APIs that merge all applicable attributes files.
9462c471	2011-11-25T08:16:26	repository: Change ownership semantics The ownership semantics have been changed all over the library to be consistent. There are no more "borrowed" or duplicated references. Main changes: - `git_repository_open2` and `3` have been dropped. - Added setters and getters to hotswap all the repository owned objects: `git_repository_index` `git_repository_set_index` `git_repository_odb` `git_repository_set_odb` `git_repository_config` `git_repository_set_config` `git_repository_workdir` `git_repository_set_workdir` Now working directories/index files/ODBs and so on can be hot-swapped after creating a repository and between operations. - All these objects now have proper ownership semantics with refcounting: they all require freeing after they are no longer needed (the repository always keeps its internal reference). - Repository open and initialization has been updated to keep in mind the configuration files. Bare repositories are now always detected, and a default config file is created on init. - All the tests affected by these changes have been dropped from the old test suite and ported to the new one.
01ad7b3a	2011-09-06T15:48:45	*: correct and codify various file permissions The following files now have 0444 permissions: - loose objects - pack indexes - pack files - packs downloaded by fetch - packs downloaded by the HTTP transport And the following files now have 0666 permissions: - config files - repository indexes - reflogs - refs This brings libgit2 more in line with Git. Note that git_filebuf_commit() and git_filebuf_commit_at() have both gained a new mode parameter. The latter change fixes an important issue where filebufs created with GIT_FILEBUF_TEMPORARY received 0600 permissions (due to mkstemp(3) usage). Now we chmod() the file before renaming it into place. Tests have been added to confirm that new commit, tag, and tree objects are created with the right permissions. I don't have access to Windows, so for now I've guarded the tests with "#ifndef GIT_WIN32".
ce8cd006	2011-09-07T15:32:44	fileops/repository: create (most) directories with 0777 permissions To further match how Git behaves, this change makes most of the directories libgit2 creates in a git repo have a file mode of 0777. Specifically: - Intermediate directories created with git_futils_mkpath2file() have 0777 permissions. This affects odb_loose, reflog, and refs. - The top level folder for bare repos is created with 0777 permissions. - The top level folder for non-bare repos is created with 0755 permissions. - /objects/info/, /objects/pack/, /refs/heads/, and /refs/tags/ are created with 0777 permissions. Additionally, the following changes have been made: - fileops functions that create intermediate directories have grown a new dirmode parameter. The only exception to this is filebuf's lock_file(), which unconditionally creates intermediate directories with 0777 permissions when GIT_FILEBUF_FORCE is set. - The test runner now sets the umask to 0 before running any tests. This ensurses all file mode checks are consistent across systems. - t09-tree.c now does a directory permissions check. I've avoided adding this check to other tests that might reuse existing directories from the prefabricated test repos. Because they're checked into the repo, they have 0755 permissions. - Other assorted directories created by tests have 0777 permissions.

afeecf4f	2011-07-09T02:10:46	odb: Direct writes are back DIRECT WRITES ARE BACK AND FASTER THAN EVER. The streaming writer to the ODB was an overkill for the smaller objects like Commit and Tags; most of the streaming logic was taking too long. This commit makes Commits, Tags and Trees to be built-up in memory, and then written to disk in 2 pushes (header + data), instead of streaming everything. This is always faster, even for big files (since the git_filebuf class still does streaming writes when the memory cache overflows). This is also a gazillion lines of code smaller, because we don't have to precompute the final size of the object before starting the stream (this was kind of defeating the point of streaming, anyway). Blobs are still written with full streaming instead of loading them in memory, since this is still the fastest way. A new `git_buf` class has been added. It's missing some features, but it'll get there.
06c43821	2011-07-09T02:37:16	Remove unused methods The direct-writes commit left some (slow) internals methods that were no longer needed. These have been removed. Also, the Reflog code was using the old `git_signature__write`, so it has been rewritten to use a normal buffer and the new `writebuf` signature writer. It's now slightly simpler and faster.

72a3fe42	2011-03-18T19:38:49	I broke your bindings Hey. Apologies in advance -- I broke your bindings. This is a major commit that includes a long-overdue redesign of the whole object-database structure. This is expected to be the last major external API redesign of the library until the first non-alpha release. Please get your bindings up to date with these changes. They will be included in the next minor release. Sorry again! Major features include: - Real caching and refcounting on parsed objects - Real caching and refcounting on objects read from the ODB - Streaming writes & reads from the ODB - Single-method writes for all object types - The external API is now partially thread-safe The speed increases are significant in all aspects, specially when reading an object several times from the ODB (revwalking) and when writing big objects to the ODB. Here's a full changelog for the external API: blob.h ------ - Remove `git_blob_new` - Remove `git_blob_set_rawcontent` - Remove `git_blob_set_rawcontent_fromfile` - Rename `git_blob_writefile` -> `git_blob_create_fromfile` - Change `git_blob_create_fromfile`: The `path` argument is now relative to the repository's working dir - Add `git_blob_create_frombuffer` commit.h -------- - Remove `git_commit_new` - Remove `git_commit_add_parent` - Remove `git_commit_set_message` - Remove `git_commit_set_committer` - Remove `git_commit_set_author` - Remove `git_commit_set_tree` - Add `git_commit_create` - Add `git_commit_create_v` - Add `git_commit_create_o` - Add `git_commit_create_ov` tag.h ----- - Remove `git_tag_new` - Remove `git_tag_set_target` - Remove `git_tag_set_name` - Remove `git_tag_set_tagger` - Remove `git_tag_set_message` - Add `git_tag_create` - Add `git_tag_create_o` tree.h ------ - Change `git_tree_entry_2object`: New signature is `(git_object *object_out, git_repository repo, git_tree_entry entry)` - Remove `git_tree_new` - Remove `git_tree_add_entry` - Remove `git_tree_remove_entry_byindex` - Remove `git_tree_remove_entry_byname` - Remove `git_tree_clearentries` - Remove `git_tree_entry_set_id` - Remove `git_tree_entry_set_name` - Remove `git_tree_entry_set_attributes` object.h ------------ - Remove `git_object_new - Remove `git_object_write` - Change `git_object_close`: This method is now mandatory. Not closing an object causes a memory leak. odb.h ----- - Remove type `git_rawobj` - Remove `git_rawobj_close` - Rename `git_rawobj_hash` -> `git_odb_hash` - Change `git_odb_hash`: New signature is `(git_oid id, const void data, size_t len, git_otype type)` - Add type `git_odb_object` - Add `git_odb_object_close` - Change `git_odb_read`: New signature is `(git_odb_object out, git_odb db, const git_oid id)` - Change `git_odb_read_header`: New signature is `(size_t len_p, git_otype type_p, git_odb db, const git_oid id)` - Remove `git_odb_write` - Add `git_odb_open_wstream` - Add `git_odb_open_rstream` odb_backend.h ------------- - Change type `git_odb_backend`: New internal signatures are as follows int ( read)(void *, size_t , git_otype , struct git_odb_backend , const git_oid ) int ( read_header)(size_t , git_otype , struct git_odb_backend , const git_oid ) int (* writestream)(struct git_odb_stream *, struct git_odb_backend , size_t, git_otype) int (* readstream)( struct git_odb_stream *, struct git_odb_backend , const git_oid *) - Add type `git_odb_stream` - Add enum `git_odb_streammode` Signed-off-by: Vicent Marti <tanoku@gmail.com>
6b2a1941	2011-03-12T23:09:16	Fix the retarded object interdependency system It's no longer retarded. All object interdependencies are stored as OIDs instead of actual objects. This should be hundreds of times faster, specially on big repositories. Heck, who knows, maye it doesn't even segfault -- wouldn't that be awesome? What has changed on the API? `git_commit_parent`, `git_commit_tree`, `git_tag_target` now return their values through a pointer-to-pointer, and have an error code. `git_commit_set_tree` and `git_tag_set_target` now return an error code and may fail. `git_repository_free__no_gc` has been deprecated because it's stupid. Since there are no longer any interdependencies between objects, we don't need internal reference counting, and GC never fails or double-free's pointers. `git_object_close` now does a very sane thing: marks an object as unused. Closed objects will be eventually free'd from the object cache based on LRU. Please use `git_object_close` from the garbage collector `destroy` method on your bindings. It's 100% safe. `git_repository_gc` is a new method that forces a garbage collector pass through the repo, to free as many LRU objects as possible. This is useful if we are running out of memory.

Individual commit messages are as follows: Added repository reference looking up functionality placeholder. Added basic reference database definition and caching infrastructure. Removed useless constant. Added GIT_EINVALIDREFNAME error and description. Added missing description for GIT_EBAREINDEX. Added GIT_EREFCORRUPTED error and description. Added GIT_ETOONESTEDSYMREF error and description. Added resolving of direct and symbolic references. Prepared the packed-refs parsing. Added parsing of the packed-refs file content. When no loose reference has been found, the full content of the packed-refs file is parsed. All of the new (i.e. not previously parsed as a loose reference) references are eagerly stored in the cached references storage. The method packed_reference_file__parse() is in deer need of some refactoring. :-) Extracted to a method the parsing of the peeled target of a tag. Extracted to a method the parsing of a standard packed ref. Fixed leaky removal of the cached references. Ensured that a previously parsed packed reference isn't returned if a more up-to-date loose reference exists. Enhanced documentation of git_repository_reference_lookup(). Moved some refs related constants from repository.c to refs.h. Made parsing of a packed tag reference more robust. Updated git_repository_reference_lookup() documentation. Added some references to the test repository. Added some tests covering tag references looking up. Added some tests covering symbolic and head references looking up. Added some tests covering packed references looking up.

58519018	2010-10-28T02:07:18	Fix internal memory management on the library String mememory is now managed in a much more sane manner. Fixes include: - git_person email and name is no longer limited to 64 characters - git_tree_entry filename is no longer limited to 255 characters - raw objects are properly opened & closed the minimum amount of times required for parsing - unit tests no longer leak - removed 5 other misc memory leaks as reported by Valgrind - tree writeback no longer segfaults on rare ocassions The git_person struct is no longer public. It is now managed by the library, and getter methods are in place to access its internal attributes. Signed-off-by: Vicent Marti <tanoku@gmail.com>
d45b4a9a	2010-09-20T21:39:11	Add support for in-memory objects All repository objects can now be created from scratch in memory using either the git_object_new() method, or the corresponding git_XXX_new() for each object.

3315782c	2010-08-08T14:12:17	Redesigned the walking/object lookup interface The old 'git_revpool' object has been removed and split into two distinct objects with separate functionality, in order to have separate methods for object management and object walking. * A new object 'git_repository' does the high-level management of a repository's objects (commits, trees, tags, etc) on top of a 'git_odb'. Eventually, it will also manage other repository attributes (e.g. tag resolution, references, etc). See: src/git/repository.h * A new external method 'git_repository_lookup(repo, oid, type)' has been added to the 'git_repository' API. All object lookups (git_XXX_lookup()) are now wrappers to this method, and duplicated code has been removed. The method does automatic type checking and returns a generic 'git_revpool_object' that can be cast to any specific object. See: src/git/repository.h * The external methods for object parsing of repository objects (git_XXX_parse()) have been removed. Loading objects from the repository is now managed through the 'lookup' functions. These objects are loaded with minimal information, and the relevant parsing is done automatically when the user requests any of the parsed attributes through accessor methods. An attribute has been added to 'git_repository' in order to force the parsing of all the repository objects immediately after lookup. See: src/git/commit.h See: src/git/tag.h See: src/git/tree.h * The previous walking functionality of the revpool is now found in 'git_revwalk', which does the actual revision walking on a repository; the attributes when walking through commits in a database have been decoupled from the actual commit objects. This increases performance when accessing commits during the walk and allows to have several 'git_revwalk' instances working at the same time on top of the same repository, without having to load commits in memory several times. See: src/git/revwalk.h * The old 'git_revpool_table' has been renamed to 'git_hashtable' and now works as a generic hashtable with support for any kind of object and custom hash functions. See: src/hashtable.h * All the relevant unit tests have been updated, renamed and grouped accordingly. Signed-off-by: Vicent Marti <tanoku@gmail.com>

repo: introduce git_repository_workdir_path Add a simple accessor for workdir paths to get an absolute on-disk path given a repository and a relative path within it. This is useful to avoid copy-pasta `git_buf_joinpath` and to ensure that we validate working directory paths while honoring `core.longpaths` settings.

path: introduce ondisk and workdir path validation Introduce `git_path_validate_filesystem` which validates (absolute) on-disk paths and `git_path_validate_workdir` to perform validations on (absolute) working directory paths. These functions are useful as there may be system limitations on on-disk paths, particularly on Windows (for example, enforcing MAX_PATH). For working directory paths, these limitations may be per-repository, based on the `core.longpaths` configuration setting.

Make sure to always include "common.h" first Next to including several files, our "common.h" header also declares various macros which are then used throughout the project. As such, we have to make sure to always include this file first in all implementation files. Otherwise, we might encounter problems or even silent behavioural differences due to macros or defines not being defined as they should be. So in fact, our header and implementation files should make sure to always include "common.h" first. This commit does so by establishing a common include pattern. Header files inside of "src" will now always include "common.h" as its first other file, separated by a newline from all the other includes to make it stand out as special. There are two cases for the implementation files. If they do have a matching header file, they will always include this one first, leading to "common.h" being transitively included as first file. If they do not have a matching header file, they instead include "common.h" as first file themselves. This fixes the outlined problems and will become our standard practice for header and source files inside of the "src/" from now on.

settings: rename `GIT_OPT_ENABLE_SYNCHRONOUS_OBJECT_CREATION` Initially, the setting has been solely used to enable the use of `fsync()` when creating objects. Since then, the use has been extended to also cover references and index files. As the option is not yet part of any release, we can still correct this by renaming the option to something more sensible, indicating not only correlation to objects. This commit renames the option to `GIT_OPT_ENABLE_FSYNC_GITDIR`. We also move the variable from the object to repository source code.

repository: rename `path_repository` and `path_gitlink` The `path_repository` variable is actually confusing to think about, as it is not always clear what the repository actually is. It may either be the path to the folder containing worktree and .git directory, the path to .git itself, a worktree or something entirely different. Actually, the intent of the variable is to hold the path to the gitdir, which is either the .git directory or the bare repository. Rename the variable to `gitdir` to avoid confusion. While at it, also rename `path_gitlink` to `gitlink` to improve consistency.

Added a `git_repository_submodule_cache_clear` function to remove the cache. Also optimized the function that loads all submodules as it was itself O(N^2) w.r.t the number of submodules, having to loop through the `.gitmodules` file once per submodule.

submodule: remove the per-repo cache Having this cache and giving them out goes against our multithreading guarantees and it makes it impossible to use submodules in a multi-threaded environment, as any thread can ask for a refresh which may reallocate some string in the submodule struct which we've accessed in a different one via a getter. This makes the submodules behave more like remotes, where each object is created upon request and not shared except explicitly by the user. This means that some tests won't pass yet, as they assume they can affect the submodule objects in the cache and that will affect later operations.

Reorganize diff and add basic diff driver This is a significant reorganization of the diff code to break it into a set of more clearly distinct files and to document the new organization. Hopefully this will make the diff code easier to understand and to extend. This adds a new `git_diff_driver` object that looks of diff driver information from the attributes and the config so that things like function content in diff headers can be provided. The full driver spec is not implemented in the commit - this is focused on the reorganization of the code and putting the driver hooks in place. This also removes a few #includes from src/repository.h that were overbroad, but as a result required extra #includes in a variety of places since including src/repository.h no longer results in pulling in the whole world.

Further threading fixes This builds on the earlier thread safety work to make it so that setting the odb, index, refdb, or config for a repository is done in a threadsafe manner with minimized locking time. This is done by adding a lock to the repository object and using it to guard the assignment of the above listed pointers. The lock is only held to assign the pointer value. This also contains some minor fixes to the other work with pack files to reduce the time that locks are being held to and fix an apparently memory leak.

Implement global/system file search paths The goal of this work is to expose the search logic for "global", "system", and "xdg" files through the git_libgit2_opts() interface. Behind the scenes, I changed the logic for finding files to have a notion of a git_strarray that represents a search path and to store a separate search path for each of the three tiers of config file. For each tier, I implemented a function to initialize it to default values (generally based on environment variables), and then general interfaces to get it, set it, reset it, and prepend new directories to it. Next, I exposed these interfaces through the git_libgit2_opts interface, reusing the GIT_CONFIG_LEVEL_SYSTEM, etc., constants for the user to control which search path they were modifying. There are alternative designs for the opts interface / argument ordering, so I'm putting this phase out for discussion. Additionally, I ended up doing a little bit of clean up regarding attr.h and attr_file.h, adding a new attrcache.h so the other two files wouldn't have to be included in so many places.

Reorg internal odb read header and object lookup Often `git_odb_read_header` will "fail" and have to read the entire object into memory instead of just the header. 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. There is no net change to the behavior of any of the existing functions, but this allows internal code to tap into the ODB lookup and object creation to be more efficient.

Add template dir and set gid to repo init This extends git_repository_init_ext further with support for initializing the repository from an external template directory and with support for the "create shared" type flags that make a set GID repository directory. 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.

Support reading attributes from index Depending on the operation, we need to consider gitattributes in both the work dir and the index. This adds a parameter to all of the gitattributes related functions that allows user control of attribute reading behavior (i.e. prefer workdir, prefer index, only use index). This fix also covers allowing us to check attributes (and hence do diff and status) on bare repositories. This was a somewhat larger change that I hoped because it had to change the cache key used for gitattributes files.

Convert hashtable usage over to khash This updates khash.h with some extra features (like error checking on allocations, ability to use wrapped malloc, foreach calls, etc), creates two high-level wrappers around khash: `git_khash_str` and `git_khash_oid` for string-to-void-ptr and oid-to-void-ptr tables, then converts all of the old usage of `git_hashtable` over to use these new hashtables. For `git_khash_str`, I've tried to create a set of macros that yield an API not too unlike the old `git_hashtable` API. Since the oid hashtable is only used in one file, I haven't bother to set up all those macros and just use the khash APIs directly for now.

Added submodule API and use in status When processing status for a newly checked out repo, it is possible that there will be submodules that have not yet been initialized. The only way to distinguish these from untracked directories is to have some knowledge of submodules. This commit adds a new submodule API which, given a name or path, can determine if it appears to be a submodule and can give information about the submodule.

Additionally, improved the handling of global and system files, making common utility functions in fileops and converting config and attr to both use the common functions. Adds a bunch more tests and fixed some memory leaks. Note that adding macros required me to use refcounted attribute assignment definitions, which complicated, but probably improved memory usage.

repository: Change ownership semantics The ownership semantics have been changed all over the library to be consistent. There are no more "borrowed" or duplicated references. Main changes: - `git_repository_open2` and `3` have been dropped. - Added setters and getters to hotswap all the repository owned objects: `git_repository_index` `git_repository_set_index` `git_repository_odb` `git_repository_set_odb` `git_repository_config` `git_repository_set_config` `git_repository_workdir` `git_repository_set_workdir` Now working directories/index files/ODBs and so on can be hot-swapped after creating a repository and between operations. - All these objects now have proper ownership semantics with refcounting: they all require freeing after they are no longer needed (the repository always keeps its internal reference). - Repository open and initialization has been updated to keep in mind the configuration files. Bare repositories are now always detected, and a default config file is created on init. - All the tests affected by these changes have been dropped from the old test suite and ported to the new one.

*: correct and codify various file permissions The following files now have 0444 permissions: - loose objects - pack indexes - pack files - packs downloaded by fetch - packs downloaded by the HTTP transport And the following files now have 0666 permissions: - config files - repository indexes - reflogs - refs This brings libgit2 more in line with Git. Note that git_filebuf_commit() and git_filebuf_commit_at() have both gained a new mode parameter. The latter change fixes an important issue where filebufs created with GIT_FILEBUF_TEMPORARY received 0600 permissions (due to mkstemp(3) usage). Now we chmod() the file before renaming it into place. Tests have been added to confirm that new commit, tag, and tree objects are created with the right permissions. I don't have access to Windows, so for now I've guarded the tests with "#ifndef GIT_WIN32".

fileops/repository: create (most) directories with 0777 permissions To further match how Git behaves, this change makes most of the directories libgit2 creates in a git repo have a file mode of 0777. Specifically: - Intermediate directories created with git_futils_mkpath2file() have 0777 permissions. This affects odb_loose, reflog, and refs. - The top level folder for bare repos is created with 0777 permissions. - The top level folder for non-bare repos is created with 0755 permissions. - /objects/info/, /objects/pack/, /refs/heads/, and /refs/tags/ are created with 0777 permissions. Additionally, the following changes have been made: - fileops functions that create intermediate directories have grown a new dirmode parameter. The only exception to this is filebuf's lock_file(), which unconditionally creates intermediate directories with 0777 permissions when GIT_FILEBUF_FORCE is set. - The test runner now sets the umask to 0 before running any tests. This ensurses all file mode checks are consistent across systems. - t09-tree.c now does a directory permissions check. I've avoided adding this check to other tests that might reuse existing directories from the prefabricated test repos. Because they're checked into the repo, they have 0755 permissions. - Other assorted directories created by tests have 0777 permissions.

odb: Direct writes are back DIRECT WRITES ARE BACK AND FASTER THAN EVER. The streaming writer to the ODB was an overkill for the smaller objects like Commit and Tags; most of the streaming logic was taking too long. This commit makes Commits, Tags and Trees to be built-up in memory, and then written to disk in 2 pushes (header + data), instead of streaming everything. This is *always* faster, even for big files (since the git_filebuf class still does streaming writes when the memory cache overflows). This is also a gazillion lines of code smaller, because we don't have to precompute the final size of the object before starting the stream (this was kind of defeating the point of streaming, anyway). Blobs are still written with full streaming instead of loading them in memory, since this is still the fastest way. A new `git_buf` class has been added. It's missing some features, but it'll get there.

Remove unused methods The direct-writes commit left some (slow) internals methods that were no longer needed. These have been removed. Also, the Reflog code was using the old `git_signature__write`, so it has been rewritten to use a normal buffer and the new `writebuf` signature writer. It's now slightly simpler and faster.

I broke your bindings Hey. Apologies in advance -- I broke your bindings. This is a major commit that includes a long-overdue redesign of the whole object-database structure. This is expected to be the last major external API redesign of the library until the first non-alpha release. Please get your bindings up to date with these changes. They will be included in the next minor release. Sorry again! Major features include: - Real caching and refcounting on parsed objects - Real caching and refcounting on objects read from the ODB - Streaming writes & reads from the ODB - Single-method writes for all object types - The external API is now partially thread-safe The speed increases are significant in all aspects, specially when reading an object several times from the ODB (revwalking) and when writing big objects to the ODB. Here's a full changelog for the external API: blob.h ------ - Remove `git_blob_new` - Remove `git_blob_set_rawcontent` - Remove `git_blob_set_rawcontent_fromfile` - Rename `git_blob_writefile` -> `git_blob_create_fromfile` - Change `git_blob_create_fromfile`: The `path` argument is now relative to the repository's working dir - Add `git_blob_create_frombuffer` commit.h -------- - Remove `git_commit_new` - Remove `git_commit_add_parent` - Remove `git_commit_set_message` - Remove `git_commit_set_committer` - Remove `git_commit_set_author` - Remove `git_commit_set_tree` - Add `git_commit_create` - Add `git_commit_create_v` - Add `git_commit_create_o` - Add `git_commit_create_ov` tag.h ----- - Remove `git_tag_new` - Remove `git_tag_set_target` - Remove `git_tag_set_name` - Remove `git_tag_set_tagger` - Remove `git_tag_set_message` - Add `git_tag_create` - Add `git_tag_create_o` tree.h ------ - Change `git_tree_entry_2object`: New signature is `(git_object **object_out, git_repository *repo, git_tree_entry *entry)` - Remove `git_tree_new` - Remove `git_tree_add_entry` - Remove `git_tree_remove_entry_byindex` - Remove `git_tree_remove_entry_byname` - Remove `git_tree_clearentries` - Remove `git_tree_entry_set_id` - Remove `git_tree_entry_set_name` - Remove `git_tree_entry_set_attributes` object.h ------------ - Remove `git_object_new - Remove `git_object_write` - Change `git_object_close`: This method is now *mandatory*. Not closing an object causes a memory leak. odb.h ----- - Remove type `git_rawobj` - Remove `git_rawobj_close` - Rename `git_rawobj_hash` -> `git_odb_hash` - Change `git_odb_hash`: New signature is `(git_oid *id, const void *data, size_t len, git_otype type)` - Add type `git_odb_object` - Add `git_odb_object_close` - Change `git_odb_read`: New signature is `(git_odb_object **out, git_odb *db, const git_oid *id)` - Change `git_odb_read_header`: New signature is `(size_t *len_p, git_otype *type_p, git_odb *db, const git_oid *id)` - Remove `git_odb_write` - Add `git_odb_open_wstream` - Add `git_odb_open_rstream` odb_backend.h ------------- - Change type `git_odb_backend`: New internal signatures are as follows int (* read)(void **, size_t *, git_otype *, struct git_odb_backend *, const git_oid *) int (* read_header)(size_t *, git_otype *, struct git_odb_backend *, const git_oid *) int (* writestream)(struct git_odb_stream **, struct git_odb_backend *, size_t, git_otype) int (* readstream)( struct git_odb_stream **, struct git_odb_backend *, const git_oid *) - Add type `git_odb_stream` - Add enum `git_odb_streammode` Signed-off-by: Vicent Marti <tanoku@gmail.com>

Fix the retarded object interdependency system It's no longer retarded. All object interdependencies are stored as OIDs instead of actual objects. This should be hundreds of times faster, specially on big repositories. Heck, who knows, maye it doesn't even segfault -- wouldn't that be awesome? What has changed on the API? `git_commit_parent`, `git_commit_tree`, `git_tag_target` now return their values through a pointer-to-pointer, and have an error code. `git_commit_set_tree` and `git_tag_set_target` now return an error code and may fail. `git_repository_free__no_gc` has been deprecated because it's stupid. Since there are no longer any interdependencies between objects, we don't need internal reference counting, and GC never fails or double-free's pointers. `git_object_close` now does a very sane thing: marks an object as unused. Closed objects will be eventually free'd from the object cache based on LRU. Please use `git_object_close` from the garbage collector `destroy` method on your bindings. It's 100% safe. `git_repository_gc` is a new method that forces a garbage collector pass through the repo, to free as many LRU objects as possible. This is useful if we are running out of memory.

Individual commit messages are as follows: Added repository reference looking up functionality placeholder. Added basic reference database definition and caching infrastructure. Removed useless constant. Added GIT_EINVALIDREFNAME error and description. Added missing description for GIT_EBAREINDEX. Added GIT_EREFCORRUPTED error and description. Added GIT_ETOONESTEDSYMREF error and description. Added resolving of direct and symbolic references. Prepared the packed-refs parsing. Added parsing of the packed-refs file content. When no loose reference has been found, the full content of the packed-refs file is parsed. All of the new (i.e. not previously parsed as a loose reference) references are eagerly stored in the cached references storage. The method packed_reference_file__parse() is in deer need of some refactoring. :-) Extracted to a method the parsing of the peeled target of a tag. Extracted to a method the parsing of a standard packed ref. Fixed leaky removal of the cached references. Ensured that a previously parsed packed reference isn't returned if a more up-to-date loose reference exists. Enhanced documentation of git_repository_reference_lookup(). Moved some refs related constants from repository.c to refs.h. Made parsing of a packed tag reference more robust. Updated git_repository_reference_lookup() documentation. Added some references to the test repository. Added some tests covering tag references looking up. Added some tests covering symbolic and head references looking up. Added some tests covering packed references looking up.

Redesigned the walking/object lookup interface The old 'git_revpool' object has been removed and split into two distinct objects with separate functionality, in order to have separate methods for object management and object walking. * A new object 'git_repository' does the high-level management of a repository's objects (commits, trees, tags, etc) on top of a 'git_odb'. Eventually, it will also manage other repository attributes (e.g. tag resolution, references, etc). See: src/git/repository.h * A new external method 'git_repository_lookup(repo, oid, type)' has been added to the 'git_repository' API. All object lookups (git_XXX_lookup()) are now wrappers to this method, and duplicated code has been removed. The method does automatic type checking and returns a generic 'git_revpool_object' that can be cast to any specific object. See: src/git/repository.h * The external methods for object parsing of repository objects (git_XXX_parse()) have been removed. Loading objects from the repository is now managed through the 'lookup' functions. These objects are loaded with minimal information, and the relevant parsing is done automatically when the user requests any of the parsed attributes through accessor methods. An attribute has been added to 'git_repository' in order to force the parsing of all the repository objects immediately after lookup. See: src/git/commit.h See: src/git/tag.h See: src/git/tree.h * The previous walking functionality of the revpool is now found in 'git_revwalk', which does the actual revision walking on a repository; the attributes when walking through commits in a database have been decoupled from the actual commit objects. This increases performance when accessing commits during the walk and allows to have several 'git_revwalk' instances working at the same time on top of the same repository, without having to load commits in memory several times. See: src/git/revwalk.h * The old 'git_revpool_table' has been renamed to 'git_hashtable' and now works as a generic hashtable with support for any kind of object and custom hash functions. See: src/hashtable.h * All the relevant unit tests have been updated, renamed and grouped accordingly. Signed-off-by: Vicent Marti <tanoku@gmail.com>
