b46708aa	2012-10-11T23:04:08	Separated git_strarray from common.h. Added doxy comments.
2d3579be	2012-10-10T14:54:31	Add git_buf_put_base64 to buffer API
02a0d651	2012-07-12T16:31:59	Add git_buf_unescape and git__unescape to unescape all characters in a string (in-place)
039fc406	2012-07-10T15:10:14	Add a couple of useful git_buf utilities * `git_buf_rfind` (with tests and tests for `git_buf_rfind_next`) * `git_buf_puts_escaped` and `git_buf_puts_escaped_regex` (with tests) to copy strings into a buffer while injecting an escape sequence (e.g. '\') in front of particular characters.
a0d95962	2012-05-17T13:14:17	Other optimization and warning fixes This fixes a warning left by the earlier optimization and addresses one of the other hotspots identified by GProf.
b59c73d3	2012-05-17T13:06:20	Optimize away git_text_gather_stats in diff GProf shows `git_text_gather_stats` as the most expensive call in large diffs. The function calculates a lot of information that is not actually used and does not do so in a optimal order. This introduces a tuned `git_buf_is_binary` function that executes the same algorithm in a fraction of the time.
2c833917	2012-05-15T16:33:05	Document git_buf_common_prefix This function fills in a git_buf with the common prefix of an array of strings, but let's make that a little more clear.
41a82592	2012-05-15T14:17:39	Ranged iterators and rewritten git_status_file The goal of this work is to rewrite git_status_file to use the same underlying code as git_status_foreach. This is done in 3 phases: 1. Extend iterators to allow ranged iteration with start and end prefixes for the range of file names to be covered. 2. Improve diff so that when there is a pathspec and there is a common non-wildcard prefix of the pathspec, it will use ranged iterators to minimize excess iteration. 3. Rewrite git_status_file to call git_status_foreach_ext with a pathspec that covers just the one file being checked. Since ranged iterators underlie the status & diff implementation, this is actually fairly efficient. The workdir iterator does end up loading the contents of all the directories down to the single file, which should ideally be avoided, but it is pretty good.

baaf1c47	2012-05-02T23:44:22	buffer: Add `git_buf_vprintf`
da3c187d	2012-04-29T19:08:48	buf: add git_buf_len() accessor to expose the current length of the buffer content
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.
cb8a7961	2012-03-07T00:02:55	error-handling: Repository This also includes droping `git_buf_lasterror` because it makes no sense in the new system. Note that in most of the places were it has been dropped, the code needs cleanup. I.e. GIT_ENOMEM is going away, so instead it should return a generic `-1` and obviously not throw anything.
ce49c7a8	2012-03-02T15:09:40	Add filter tests and fix some bugs This adds some initial unit tests for file filtering and fixes some simple bugs in filter application.
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.

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).
bf6d2717	2011-12-14T03:27:53	buffer: inline `git_buf_cstr`
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.
309113c9	2011-11-29T23:45:17	Make initial value of git_buf ptr always be a valid empty string. Taking a page from core git's strbuf, this introduces git_buf_initbuf which is an empty string that is used to initialize the git_buf ptr value even for new buffers. Now the git_buf ptr will always point to a valid NUL-terminated string. This change required jumping through a few hoops for git_buf_grow and git_buf_free to distinguish between a actual allocated buffer and the global initial value. Also, this moves the allocation related functions to be next to each other near the top of buffer.c.
c63728cd	2011-11-29T16:39:49	Make git_buf functions always maintain a valid cstr. At a tiny cost of 1 extra byte per allocation, this makes git_buf_cstr into basically a noop, which simplifies error checking when trying to convert things to use dynamic allocation. This patch also adds a new function (git_buf_copy_cstr) for copying the cstr data directly into an external buffer.
3aa294fd	2011-11-28T10:42:57	Add two string git_buf_join and tweak input error checking. This commit addresses two of the comments: * renamed existing n-input git_buf_join to git_buf_join_n * added new git_buf_join that always takes two inputs * moved some parameter error checking to asserts * extended unit tests to cover new version of git_buf_join
8c74d22e	2011-11-27T21:47:58	Extend git_buf with new utility functions and unit tests. Add new functions to git_buf for: * initializing a buffer from a string * joining one or more strings onto a buffer with separators * swapping two buffers in place * extracting data from a git_buf (leaving it empty) Also, make git_buf_free leave a git_buf back in its initted state, and slightly tweak buffer allocation sizes and thresholds. Finally, port unit tests to clay and extend with lots of new tests for the various git_buf functions.

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.
