Russell Belfer 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.
Russell Belfer 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.
Russell Belfer 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.

Russell Belfer 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.
Russell Belfer 679b69c4 2011-11-28T13:05:25 Resolve remaining feedback * replace some ints with size_ts * update NULL checks in various places
Russell Belfer 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
Russell Belfer 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.
