	3ccc1a4d	2017-11-19T09:46:02		futils: add a function to truncate a file We want to do this in order to get FETCH_HEAD to be empty when we start updating it due to fetching from the remote.
	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.

	5312621b	2016-12-15T10:51:02		git_futils_writebuffer: optionally fsync Add a custom `O_FSYNC` bit (if it's not been defined by the operating system`) so that `git_futils_writebuffer` can optionally do an `fsync` when it's done writing. We call `fsync` ourselves, even on systems that define `O_FSYNC` because its definition is no guarantee of its actual support. Mac, for instance, defines it but doesn't support it in an `open(2)` call.

	27051d4e	2016-07-22T13:34:19		odb: only freshen pack files every 2 seconds Since writing multiple objects may all already exist in a single packfile, avoid freshening that packfile repeatedly in a tight loop. Instead, only freshen pack files every 2 seconds.
	8f09a98e	2016-07-14T16:23:24		odb: freshen existing objects when writing When writing an object, we calculate its OID and see if it exists in the object database. If it does, we need to freshen the file that contains it.

	eb597799	2015-10-29T21:12:37		filebuf: use a checksum to detect file changes Instead of relying on the size and timestamp, which can hide changes performed in the same second, hash the file content's when we care about detecting changes.

	ac2fba0e	2015-09-16T15:07:27		git_futils_mkdir_*: make a relative-to-base mkdir Untangle git_futils_mkdir from git_futils_mkdir_ext - the latter assumes that we own everything beneath the base, as if it were being called with a base of the repository or working directory, and is tailored towards checkout and ensuring that there is no bogosity beneath the base that must be cleaned up. This is (at best) slow and (at worst) unsafe in the larger context of a filesystem where we do not own things and cannot do things like unlink symlinks that are in our way.

	e74340b0	2015-01-14T18:47:00		checkout: remove files before writing new ones On case insensitive filesystems, we may have files in the working directory that case fold to a name we want to write. Remove those files (by default) so that we will not end up with a filename that has the unexpected case.
	1d50b364	2015-01-12T16:16:27		checkout: introduce git_checkout_perfdata Checkout can now provide performance data about the number of (some) syscalls performed using an optional callback.
	94f742ba	2014-05-28T10:18:05		fileops: allow linking files when copying directory structures When passed the LINK_FILES flag, the recursive copy will hardlink files instead of copying them.
	823c0e9c	2014-04-17T11:53:13		Fix broken logic for attr cache invalidation The checks to see if files were out of date in the attibute cache was wrong because the cache-breaker data wasn't getting stored correctly. Additionally, when the cache-breaker triggered, the old file data was being leaked.
	7d490872	2014-04-10T22:31:01		Attribute file cache refactor This is a big refactoring of the attribute file cache to be a bit simpler which in turn makes it easier to enforce a lock around any updates to the cache so that it can be used in a threaded env. Tons of changes to the attributes and ignores code.

	1d3a8aeb	2013-11-04T18:28:57		move mode_t to filebuf_open instead of _commit
	219d3457	2013-10-01T16:12:15		Initial iconv hookup for precomposed unicode This hooks up git_path_direach and git_path_dirload so that they will take a flag indicating if directory entry names should be tested and converted from decomposed unicode to precomposed form. This code will only come into play on the Apple platform and even then, only when certain types of filesystems are used. This involved adding a flag to these functions which involved changing a lot of places in the code. This was an opportunity to do a bit of code cleanup here and there, for example, getting rid of the git_futils_cleanupdir_r function in favor of a simple flag to git_futils_rmdir_r to not remove the top level entry. That ended up adding depth tracking during rmdir_r which led to a safety check for infinite directory recursion. Yay. This hasn't actually been tested on the Mac filesystems where the issue occurs. I still need to get test environment for that.
	3d4f1698	2013-09-17T10:21:22		Merge pull request #1858 from linquize/win32-template-dir Configurable template dir for Win32
	a3aa5f4d	2013-09-11T12:45:20		Add simple global shutdown hooks Increasingly there are a number of components that want to do some cleanup at global shutdown time (at least if there are not going to be memory leaks). This creates a very simple system of shutdown hooks that will be invoked by git_threads_shutdown. Right now, the maximum number of hooks is hardcoded, but since adding a hook is not a public API, it should be fine and I thought it was better to start off with really simple code.
	a025907e	2013-09-17T23:55:11		Can load default template directory

	a7fcc44d	2013-09-05T16:14:32		Better macro name for is-exec-bit-set test
	af22dabb	2013-09-05T12:01:17		GIT_MODE_TYPE should exclude setgid bits The GIT_MODE_TYPE macro was looking at all bits above the permissions, but it should really just look at the top bits so that it will give the right results for a setgid or setuid entry. Since we're now using these macros in the tests, this was causing a test failure on platforms that don't support setgid.
	f240acce	2013-09-05T11:20:12		Add more file mode permissions macros This adds some more macros for some standard operations on file modes, particularly related to permissions, and then updates a number of places around the code base to use the new macros.
	c05a55b0	2013-07-23T09:40:19		Clean up some documentation clang's docparser highlighted these.
	0a1c8f55	2013-07-11T17:09:15		preload configuration paths
	4742148d	2013-05-20T13:41:39		Add more diff rename detection tests This adds a bunch more rename detection tests including checks vs the working directory, the new exact match options, some more whitespace variants, etc. This also adds a git_futils_writebuffer helper function and uses it in checkout. This is mainly added because I wanted an easy way to write out a git_buf to disk inside my test code.
	9be5be47	2013-05-20T13:37:21		More git_diff_find_similar improvements - Add new GIT_DIFF_FIND_EXACT_MATCH_ONLY flag to do similarity matching without using the similarity metric (i.e. only compare the SHA). - Clean up the similarity measurement code to more rigorously distinguish between files that are not similar and files that are not comparable (previously, a 0 could either mean that the files could not be compared or that they were totally different) - When splitting a MODIFIED file into a DELETE/ADD pair, actually make a DELETED/UNTRACKED pair if the right side of the diff is from the working directory. This prevents an odd mix of ADDED and UNTRACKED files on workdir diffs.
	41954a49	2013-03-18T14:19:35		Switch search paths to classic delimited strings This switches the APIs for setting and getting the global/system search paths from using git_strarray to using a simple string with GIT_PATH_LIST_SEPARATOR delimited paths, just as the environment PATH variable would contain. This makes it simpler to get and set the value. I also added code to expand "$PATH" when setting a new value to embed the old value of the path. This means that I no longer require separate actions to PREPEND to the value.
	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.
	b72f5d40	2013-03-05T15:35:28		Merge pull request #1369 from arrbee/repo-init-template-hooks More tests (and fixes) for initializing repo from template
	926acbcf	2013-03-01T11:07:53		Clone should not delete directories it did not create
	18f08264	2013-02-27T13:44:15		Make mode handling during init more like git When creating files, instead of actually using GIT_FILEMODE_BLOB and the other various constants that happen to correspond to mode values, apparently I should be just using 0666 and 0777, and relying on the umask to clear bits and make the value sane. This fixes the rules for copying a template directory and fixes the checks to match that new behavior. (Further changes to the checkout logic to follow separately.)
	3c42e4ef	2013-02-26T11:43:14		Fix initialization of repo directories When PR #1359 removed the hooks from the test resources/template directory, it made me realize that the tests for git_repository_init_ext using templates must be pretty shabby because we could not have been testing if the hooks were getting created correctly. So, this started with me recreating a couple of hooks, including a sample and symlink, and adding tests that they got created correctly in the various circumstances, including with the SHARED modes, etc. Unfortunately this uncovered some issues with how directories and symlinks were copied and chmod'ed. Also, there was a FIXME in the code related to the chmod behavior as well. Going back over the directory creation logic for setting up a repository, I found it was a little difficult to read and could result in creating and/or chmod'ing directories that the user almost certainly didn't intend. So that let to this work which makes repo initialization much more careful (and hopefully easier to follow). It required a couple of extensions / changes to core fileops utilities, but I also think those are for the better, at least for git_futils_cp_r in terms of being careful about what actions it takes.
	359fc2d2	2013-01-08T17:07:25		update copyrights
	ad9a921b	2012-11-08T17:05:07		Rework checkout with new strategy options This is a major reworking of checkout strategy options. The checkout code is now sensitive to the contents of the HEAD tree and the new options allow you to update the working tree so that it will match the index content only when it previously matched the contents of the HEAD. This allows you to, for example, to distinguish between removing files that are in the HEAD but not in the index, vs just removing all untracked files. Because of various corner cases that arise, etc., this required some additional capabilities in rmdir and other utility functions. This includes the beginnings of an implementation of code to read a partial tree into the index based on a pathspec, but that is not enabled because of the possibility of creating conflicting index entries.
	331e7de9	2012-10-24T17:32:50		Extensions to rmdir and mkdir utilities * Rework GIT_DIRREMOVAL values to GIT_RMDIR flags, allowing combinations of flags * Add GIT_RMDIR_EMPTY_PARENTS flag to remove parent dirs that are left empty after removal * Add GIT_MKDIR_VERIFY_DIR to give an error if item is a file, not a dir (previously an EEXISTS error was ignored, even for files) and enable this flag for git_futils_mkpath2file call * Improve accuracy of error messages from git_futils_mkdir
	c1f61af6	2012-10-31T20:52:01		I LIKE THESE NAMES
	c8b511f3	2012-10-31T11:26:12		Better naming for file timestamp/size checker
	744cc03e	2012-10-30T12:10:36		Add git_config_refresh() API to reload config This adds a new API that allows users to reload the config if the file has changed on disk. A new config callback function to refresh the config was added. The modified time and file size are used to test if the file needs to be reloaded (and are now stored in the disk backend object). In writing tests, just using mtime was a problem / race, so I wanted to check file size as well. To support that, I extended `git_futils_readbuffer_updated` to optionally check file size in addition to mtime, and I added a new function `git_filebuf_stats` to fetch the mtime and size for an open filebuf (so that the config could be easily refreshed after a write). Lastly, I moved some similar file checking code for attributes into filebuf. It is still only being used for attrs, but it seems potentially reusable, so I thought I'd move it over.
	0d64bef9	2012-10-05T15:56:57		Add complex checkout test and then fix checkout This started as a complex new test for checkout going through the "typechanges" test repository, but that revealed numerous issues with checkout, including: * complete failure with submodules * failure to create blobs with exec bits * problems when replacing a tree with a blob because the tree "example/" sorts after the blob "example" so the delete was being processed after the single file blob was created This fixes most of those problems and includes a number of other minor changes that made it easier to do that, including improving the TYPECHANGE support in diff/status, etc.
	60b9d3fc	2012-09-05T15:00:40		Implement filters for status/diff blobs This adds support to diff and status for running filters (a la crlf) on blobs in the workdir before computing SHAs and before generating text diffs. This ended up being a bit more code change than I had thought since I had to reorganize some of the diff logic to minimize peak memory use when filtering blobs in a diff. 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. Right now it is a #define in src/diff.h but it could be moved into the public API if desired.
	85bd1746	2012-08-22T16:03:35		Some cleanup suggested during review This cleans up a number of items suggested during code review with @vmg, including: * renaming "outside repo" config API to `git_config_open_default` * killing the `git_config_open_global` API * removing the `git_` prefix from the static functions in fileops * removing some unnecessary functionality from the "cp" command
	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.

	0d0fa7c3	2012-03-16T15:56:01		Convert attr, ignore, mwindow, status to new errors Also cleaned up some previously converted code that still had little things to polish.
	deafee7b	2012-03-14T17:36:15		Continue error conversion This converts blob.c, fileops.c, and all of the win32 files. Also, various minor cleanups throughout the code. Plus, in testing the win32 build, I cleaned up a bunch (although not all) of the warnings with the 64-bit build.
	ae9e29fd	2012-03-06T16:14:31		Migrating diff to new error handling Ended up migrating a bunch of upstream functions as well including vector, attr_file, and odb in order to get this to work right.
	74fa4bfa	2012-02-28T16:14:47		Update diff to use iterators This is a major reorganization of the diff code. This changes the diff functions to use the iterators for traversing the content. This allowed a lot of code to be simplified. Also, this moved the functions relating to outputting a diff into a new file (diff_output.c). This includes a number of other changes - adding utility functions, extending iterators, etc. plus more tests for the diff code. This also takes the example diff.c program much further in terms of emulating git-diff command line options.
	13224ea4	2012-02-27T04:28:31		buffer: Unify `git_fbuffer` and `git_buf` This makes so much sense that I can't believe it hasn't been done before. Kill the old `git_fbuffer` and read files straight into `git_buf` objects. Also: In order to fully support 4GB files in 32-bit systems, the `git_buf` implementation has been changed from using `ssize_t` for storage and storing negative values on allocation failure, to using `size_t` and changing the buffer pointer to a magical pointer on allocation failure. Hopefully this won't break anything.
	b6c93aef	2012-02-21T14:46:24		Uniform iterators for trees, index, and workdir This create a new git_iterator type of object that provides a uniform interface for iterating over the index, an arbitrary tree, or the working directory of a repository. As part of this, git ignore support was extended to support push and pop of directory-based ignore files as the working directory is being traversed (so the array of ignores does not have to be recreated at each directory during traveral). There are a number of other small utility functions in buffer, path, vector, and fileops that are included in this patch that made the iterator implementation cleaner.

	1744fafe	2012-01-17T15:49:47		Move path related functions from fileops to path This takes all of the functions that look up simple data about paths (such as `git_futils_isdir`) and moves them over to path.h (becoming `git_path_isdir`). This leaves fileops.h just with functions that actually manipulate the filesystem or look at the file contents in some way. As part of this, the dir.h header which is really just for win32 support was moved into win32 (with some minor changes).
	6a67a812	2012-01-11T16:01:48		Allow ignores (and attribs) for nonexistent files This fixes issue 532 that attributes (and gitignores) could not be checked for files that don't exist. It should be possible to query such things regardless of the existence of the file.
	df743c7d	2012-01-09T15:37:19		Initial implementation of gitignore support Adds support for .gitignore files to git_status_foreach() and git_status_file(). 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.
	97769280	2011-11-30T11:27:15		Use git_buf for path storage instead of stack-based buffers This converts virtually all of the places that allocate GIT_PATH_MAX buffers on the stack for manipulating paths to use git_buf objects instead. The patch is pretty careful not to touch the public API for libgit2, so there are a few places that still use GIT_PATH_MAX. This extends and changes some details of the git_buf implementation to add a couple of extra functions and to make error handling easier. This includes serious alterations to all the path.c functions, and several of the fileops.c ones, too. Also, there are a number of new functions that parallel existing ones except that use a git_buf instead of a stack-based buffer (such as git_config_find_global_r that exists alongsize git_config_find_global). This also modifies the win32 version of p_realpath to allocate whatever buffer size is needed to accommodate the realpath instead of hardcoding a GIT_PATH_MAX limit, but that change needs to be tested still.

	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.

	87d9869f	2011-09-19T03:34:49		Tabify everything There were quite a few places were spaces were being used instead of tabs. Try to catch them all. This should hopefully not break anything. Except for `git blame`. Oh well.
	bb742ede	2011-09-19T01:54:32		Cleanup legal data 1. The license header is technically not valid if it doesn't have a copyright signature. 2. The COPYING file has been updated with the different licenses used in the project. 3. The full GPLv2 header in each file annoys me.
	c3da9f06	2011-07-21T22:55:20		Add git_futils_readbuffer_updated This extends the git_fuitls_readbuffer function to only read in if the file's modification date is later than the given one. Some code paths want to check a file's modification date in order to decide whether they should read it or not. If they do want to read it, another stat call is done by futils. This function combines these two operations so we avoid one stat call each time we read a new or updated file. The git_futils_readbuffer functions is now a wrapper around the new function.

	eec3fe39	2011-07-05T01:11:33		fileutils: Finish dropping the old `prettify_path`
	5ad739e8	2011-07-04T20:05:11		fileops: Drop `git_fileops_prettify_path` The old `git_fileops_prettify_path` has been replaced with `git_path_prettify`. This is a much simpler method that uses the OS's `realpath` call to obtain the full path for directories and resolve symlinks. The `realpath` syscall is the original POSIX call in Unix system and an emulated version under Windows using the Windows API.
	f79026b4	2011-07-04T11:43:34		fileops: Cleanup Cleaned up the structure of the whole OS-abstraction layer. fileops.c now contains a set of utility methods for file management used by the library. These are abstractions on top of the original POSIX calls. There's a new file called `posix.c` that contains emulations/reimplementations of all the POSIX calls the library uses. These are prefixed with `p_`. There's a specific posix file for each platform (win32 and unix). All the path-related methods have been moved from `utils.c` to `path.c` and have their own prefix.

	6ac91dfe	2011-06-29T14:06:18		Hide ".git" directory on Windows upon creation of a non bare repository Directory which name starts with a dot are hidden on Linux platforms. This patch makes libgit2 behaves similarly on Windows.
	ef9a6f4c	2011-06-15T13:47:41		Merge pull request #261 from Romain-Geissler/discovery-path-v2 Fix: GIT_PATH_PATH_SEPARATOR is now a semi-colon under Windows.
	0657e46d	2011-06-15T12:36:08		Fix: GIT_PATH_PATH_SEPARATOR is now a semi-colon under Windows. GIT_PATH_LIST_SEPARATOR and GIT_PATH_MAX are made public so that it's can be used by a client.
	e6480970	2011-06-10T14:00:54		Add missing function declarations to avoid MSVC compiler warnings The better solution would probably be to turn the gitfo_lstat / gitfo_readlink macros into real functions that wrap either lstat or gitfo_lstat__w32 (and readlink or gitfo_readlink__w32). However, that would introduce an indirection unless inlined. For now, this is the less intrusive change.
	ae496955	2011-06-08T17:03:41		windows: Fix Symlink issues Handle Symlinks if they can be handled in Win32. This is not even compiled. Needs review. The lstat implementation is modified from core Git. The readlink implementation is modified from PHP.

	1869b31e	2011-05-25T16:11:57		index/fileops: Correctly process symbolic links gitfo_exists() used to error out if the given file was a symbolic link, due to access() returning an error code. This is not expected behaviour, as gitfo_exists() should only check whether the file itself exists, not its link target if it is a symbolic link. Fix this by calling gitfo_lstat() instead, which is just a wrapper for lstat(). Also fix the same error in index_init_entry().
	ff9a4c13	2011-06-06T17:14:30		Tree: Added a function that returns the type of a tree entry.
	f2e6b877	2011-06-03T23:44:38		Repository: Added some util functions that we'll need to discover repository path. retrieve_device returns the file device for a given path (so that we can detect device change while walking through parent directories). abspath returns a canonicalized path, symbolic link free. retrieive_ceiling_directories_offset returns the biggest path offset that path match in the ceiling directory list (so that we can stop at ceiling directories).
	1549cba9	2011-06-03T21:18:24		Filebuf: Fixed a TODO in filebuf (real lock in lock_file) Added gitfo_creat_locked and gitfo_creat_locked_force
	bc648491	2011-06-03T21:09:14		Fileops: Added gitfo_isfile. Conflicts: src/fileops.c
	26a98ec8	2011-06-03T20:47:56		Fileops: Added a fourth argument to the path prettifying functions to use an alternate basepath. Fixed a Windows TO-DO in the prettifying functions.
	bb88da7f	2011-06-03T19:38:46		Sha1Lookup: Fixed two MSVC compilation warnings.
	04fdc10d	2011-06-03T19:26:45		Fileops:retrieve_path_root_offset is now named gitfo_retrieve_path_root_offset (like other public functions). Added platform specific directory separator definition.

	f6f72d7e	2011-03-23T18:44:53		Improve the ODB writing backend Temporary files when doing streaming writes are now stored inside the Objects folder, to prevent issues when moving files between disks/partitions. Add support for block writes to the ODB again (for those backends that cannot implement streaming).
