* Add efficient git_buf join3 APIRussell Belfer2014-04-011-0/+53
| | | | | | | There are a few places where we need to join three strings to assemble a path. This adds a simple join3 function to avoid the comparatively expensive join_n (which calls strlen on each string twice).

* | Merge git_buf and git_bufferRussell Belfer2013-09-171-74/+19
| | | | | | | | | | | | | | | | | | | | | | 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.
* | Add functions to manipulate filter listsRussell Belfer2013-09-171-1/+2
| | | | | | | | | | | | | | | | Extend the git2/sys/filter API with functions to look up a filter and add it manually to a filter list. This requires some trickery because the regular attribute lookups and checks are bypassed when this happens, but in the right hands, it will allow a user to have granular control over applying filters.
* | Extend public filter api with filter listsRussell Belfer2013-09-171-3/+20
| | | | | | | | | | | | | | | | | | | | | | This moves the git_filter_list into the public API so that users can create, apply, and dispose of filter lists. This allows more granular application of filters to user data outside of libgit2 internals. This also converts all the internal usage of filters to the public APIs along with a few small tweaks to make it easier to use the public git_buffer stuff alongside the internal git_buf.
* | Start of filter API + git_blob_filtered_contentRussell Belfer2013-09-171-0/+54
|/ | | | | | | | | | This begins the process of exposing git_filter objects to the public API. This includes: * new public type and API for `git_buffer` through which an allocated buffer can be passed to the user * new API `git_blob_filtered_content` * make the git_filter type and GIT_FILTER_TO_... constants public

* Consolidate text buffer functionsRussell Belfer2012-11-281-108/+6
| | | | | | | | | | | | | There are many scattered functions that look into the contents of buffers to do various text manipulations (such as escaping or unescaping data, calculating text stats, guessing if content is binary, etc). This groups all those functions together into a new file and converts the code to use that. This has two enhancements to existing functionality. The old text stats function is significantly rewritten and the BOM detection code was extended (although largely we can't deal with anything other than a UTF8 BOM).

* Other optimization and warning fixesRussell Belfer2012-05-171-11/+16
| | | | | This fixes a warning left by the earlier optimization and addresses one of the other hotspots identified by GProf.
* Optimize away git_text_gather_stats in diffRussell Belfer2012-05-171-0/+18
| | | | | | | | 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.
* Document git_buf_common_prefixRussell Belfer2012-05-151-0/+3
| | | | | 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.
* Ranged iterators and rewritten git_status_fileRussell Belfer2012-05-151-0/+27
| | | | | | | | | | | | | | | | | | | | | 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.

* Implement git_pool paged memory allocatorRussell Belfer2012-04-251-1/+1
| | | | | | | | | | | | | | | | | | 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 bufferRussell Belfer2012-03-301-6/+18
| | | | | | 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.
* Convert attr, ignore, mwindow, status to new errorsRussell Belfer2012-03-161-22/+18
| | | | | Also cleaned up some previously converted code that still had little things to polish.
* Continue error conversionRussell Belfer2012-03-141-2/+2
| | | | | | | 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: RepositoryVicent Martí2012-03-071-7/+2
| | | | | | | | 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.
* Add filter tests and fix some bugsRussell Belfer2012-03-021-0/+7
| | | | | This adds some initial unit tests for file filtering and fixes some simple bugs in filter application.
* buffer: Null terminate on rtrimVicent Martí2012-02-271-0/+2

* filter: Apply filters before writing a file to the ODBVicent Martí2012-02-271-1/+1
| | | | | | | | | | | | | | | | | | | | 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`Vicent Martí2012-02-271-15/+30
| | | | | | | | | | | | | | 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 workdirRussell Belfer2012-02-211-1/+7
| | | | | | | | | | | | | | | 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.

* Fix several memory issuesRussell Belfer2012-01-111-1/+1
| | | | | | | 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.
* Initial implementation of gitignore supportRussell Belfer2012-01-111-3/+5
| | | | | | | | 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-joinsRussell Belfer2011-12-141-2/+16
| | | | | | | | | | | | 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`Vicent Marti2011-12-141-5/+0

* Use git_buf for path storage instead of stack-based buffersRussell Belfer2011-12-071-22/+74
| | | | | | | | | | | | | | | | | | | | 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.Russell Belfer2011-11-301-49/+15
| | | | | | | 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.Russell Belfer2011-11-291-34/+56
| | | | | | | | | | | | 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.Russell Belfer2011-11-291-14/+32
| | | | | | | | | 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.
