Jeff King	7202a6fa87	encode_in_pack_object_header: respect output buffer length The encode_in_pack_object_header() writes a variable-length header to an output buffer, but it doesn't actually know long the buffer is. At first glance, this looks like it might be possible to overflow. In practice, this is probably impossible. The smallest buffer we use is 10 bytes, which would hold the header for an object up to 2^67 bytes. Obviously we're not likely to see such an object, but we might worry that an object could lie about its size (causing us to overflow before we realize it does not actually have that many bytes). But the argument is passed as a uintmax_t. Even on systems that have __int128 available, uintmax_t is typically restricted to 64-bit by the ABI. So it's unlikely that a system exists where this could be exploited. Still, it's easy enough to use a normal out/len pair and make sure we don't write too far. That protects the hypothetical 128-bit system, makes it harder for callers to accidentally specify a too-small buffer, and makes the resulting code easier to audit. Note that the one caller in fast-import tried to catch such a case, but did so _after_ the call (at which point we'd have already overflowed!). This check can now go away.

Junio C Hamano	8de7eeb54b	compression: unify pack.compression configuration parsing There are three codepaths that use a variable whose name is pack_compression_level to affect how objects and deltas sent to a packfile is compressed. Unlike zlib_compression_level that controls the loose object compression, however, this variable was static to each of these codepaths. Two of them read the pack.compression configuration variable, using core.compression as the default, and one of them also allowed overriding it from the command line. The other codepath in bulk-checkin did not pay any attention to the configuration. Unify the configuration parsing to git_default_config(), where we implement the parsing of core.loosecompression and core.compression and make the former override the latter, by moving code to parse pack.compression and also allow core.compression to give default to this variable.

Jeff King	ef1286d3c0	use xsnprintf for generating git object headers We generally use 32-byte buffers to format git's "type size" header fields. These should not generally overflow unless you can produce some truly gigantic objects (and our types come from our internal array of constant strings). But it is a good idea to use xsnprintf to make sure this is the case. Note that we slightly modify the interface to write_sha1_file_prepare, which nows uses "hdrlen" as an "in" parameter as well as an "out" (on the way in it stores the allocated size of the header, and on the way out it returns the ultimate size of the header).

David Aguilar	1c4b660412	cleanups: ensure that git-compat-util.h is included first CodingGuidelines states that the first #include in C files should be git-compat-util.h or another header file that includes it, such as cache.h or builtin.h.

Sun He	5889271114	finish_tmp_packfile():use strbuf for pathname construction The old version fixes a maximum length on the buffer, which could be a problem if one is not certain of the length of get_object_directory().

Johannes Sixt	e92527c97c	stream_to_pack: xread does not guarantee to read all requested bytes The deflate loop in bulk-checkin::stream_to_pack expects to get all bytes from a file that it requests to read in a single function call. But it used xread(), which does not give that guarantee. Replace it by read_in_full(). Signed-off-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>	12 years ago
Junio C Hamano	568508e765	bulk-checkin: replace fast-import based implementation This extends the earlier approach to stream a large file directly from the filesystem to its own packfile, and allows "git add" to send large files directly into a single pack. Older code used to spawn fast-import, but the new bulk-checkin API replaces it. Signed-off-by: Junio C Hamano <gitster@pobox.com>	13 years ago
