1e4976cb	2014-05-08T10:17:14	Be more careful with user-supplied buffers This adds in missing calls to `git_buf_sanitize` and fixes a number of places where `git_buf` APIs could inadvertently write NUL terminator bytes into invalid buffers. This also changes the behavior of `git_buf_sanitize` to NUL terminate a buffer if it can and of `git_buf_shorten` to do nothing if it can. Adds tests of filtering code with zeroed (i.e. unsanitized) buffer which was previously triggering a segfault.

a9f51e43	2013-09-11T22:00:36	Merge git_buf and git_buffer This makes the git_buf struct that was used internally into an externally available structure and eliminates the git_buffer. As part of that, some of the special cases that arose with the externally used git_buffer were blended into the git_buf, such as being careful about git_buf objects that may have a NULL ptr and allowing for bufs with a valid ptr and size but zero asize as a way of referring to externally owned data.

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.

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`
2bc8fa02	2012-04-17T10:14:24	Implement git_pool paged memory allocator This adds a `git_pool` object that can do simple paged memory allocation with free for the entire pool at once. Using this, you can replace many small allocations with large blocks that can then cheaply be doled out in small pieces. This is best used when you plan to free the small blocks all at once - for example, if they represent the parsed state from a file or data stream that are either all kept or all discarded. There are two real patterns of usage for `git_pools`: either for "string" allocation, where the item size is a single byte and you end up just packing the allocations in together, or for "fixed size" allocation where you are allocating a large object (e.g. a `git_oid`) and you generally just allocation single objects that can be tightly packed. Of course, you can use it for other things, but those two cases are the easiest.
952f94c8	2012-03-30T14:42:23	Fix bug when join_n refers to original buffer There was a bug in git_buf_join_n when the contents of the original buffer were joined into itself and the realloc moved the pointer to the original buffer.
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.

44b1ff4c	2012-02-27T04:31:05	filter: Apply filters before writing a file to the ODB Initial implementation. The relevant code is in `blob.c`: the blob write function has been split into smaller functions. - Directly write a file to the ODB in streaming mode - Directly write a symlink to the ODB in direct mode - Apply a filter, and write a file to the ODB in direct mode When trying to write a file, we first call `git_filter__load_for_file`, which populates a filters array with the required filters based on the filename. If no filters are resolved to the filename, we can write to the ODB in streaming mode straight from disk. Otherwise, we load the whole file in memory and use double-buffering to apply the filter chain. We finish by writing the file as a whole to the ODB.
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.

1dbcc9fc	2012-01-11T21:07:16	Fix several memory issues This contains fixes for several issues discovered by MSVC and by valgrind, including some bad data access, some memory leakage (in where certain files were not being successfully added to the cache), and some code simplification.
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).
b5daae68	2011-12-14T12:34:43	Allow git_buf_joinpath to accept self-joins It was not safe for git_buf_joinpath to be used with a pointer into the buf itself because a reallocation could invalidate the input parameter that pointed into the buffer. This patch makes it safe to self join, at least for the leading input to the join, which is the common "append" case for self joins. Also added unit tests to explicitly cover this case. This should actually fix #511
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.
969d588d	2011-11-30T13:10:47	Optimized of git_buf_join. This streamlines git_buf_join and removes the join-append behavior, opting instead for a very compact join-replace of the git_buf contents. The unit tests had to be updated to remove the join-append tests and have a bunch more exhaustive tests added.
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.
679b69c4	2011-11-28T13:05:25	Resolve remaining feedback * replace some ints with size_ts * update NULL checks in various places
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.

Implement git_pool paged memory allocator This adds a `git_pool` object that can do simple paged memory allocation with free for the entire pool at once. Using this, you can replace many small allocations with large blocks that can then cheaply be doled out in small pieces. This is best used when you plan to free the small blocks all at once - for example, if they represent the parsed state from a file or data stream that are either all kept or all discarded. There are two real patterns of usage for `git_pools`: either for "string" allocation, where the item size is a single byte and you end up just packing the allocations in together, or for "fixed size" allocation where you are allocating a large object (e.g. a `git_oid`) and you generally just allocation single objects that can be tightly packed. Of course, you can use it for other things, but those two cases are the easiest.

Fix bug when join_n refers to original buffer There was a bug in git_buf_join_n when the contents of the original buffer were joined into itself and the realloc moved the pointer to the original buffer.

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.

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.

buffer: Null terminate on rtrim

filter: Apply filters before writing a file to the ODB Initial implementation. The relevant code is in `blob.c`: the blob write function has been split into smaller functions. - Directly write a file to the ODB in streaming mode - Directly write a symlink to the ODB in direct mode - Apply a filter, and write a file to the ODB in direct mode When trying to write a file, we first call `git_filter__load_for_file`, which populates a filters array with the required filters based on the filename. If no filters are resolved to the filename, we can write to the ODB in streaming mode straight from disk. Otherwise, we load the whole file in memory and use double-buffering to apply the filter chain. We finish by writing the file as a whole to the ODB.

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.

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.

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).

Allow git_buf_joinpath to accept self-joins It was not safe for git_buf_joinpath to be used with a pointer into the buf itself because a reallocation could invalidate the input parameter that pointed into the buffer. This patch makes it safe to self join, at least for the leading input to the join, which is the common "append" case for self joins. Also added unit tests to explicitly cover this case. This should actually fix #511

buffer: inline `git_buf_cstr`

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.

Optimized of git_buf_join. This streamlines git_buf_join and removes the join-append behavior, opting instead for a very compact join-replace of the git_buf contents. The unit tests had to be updated to remove the join-append tests and have a bunch more exhaustive tests added.

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.

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.

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.

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.
