* 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

* 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.
* Resolve remaining feedbackRussell Belfer2011-11-281-15/+13
| | | | | * replace some ints with size_ts * update NULL checks in various places
* Add two string git_buf_join and tweak input error checking.Russell Belfer2011-11-281-8/+68
| | | | | | | | 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
* Extend git_buf with new utility functions and unit tests.Russell Belfer2011-11-271-8/+136
| | | | | | | | | | | | | | 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.

|/ | | | | | | | | | 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.
* odb: Direct writes are backVicent Marti2011-07-091-0/+95
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.
