Martin Koegler	adb7b5fc86	Fix compilation of test-delta The code used write_in_full() without pulling its declarations from the header file. When header is included, usage[] collides with usage() function. Signed-off-by: Martin Koegler <mkoegler@auto.tuwien.ac.at> Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Andy Whitcroft	93822c2239	short i/o: fix calls to write to use xwrite or write_in_full We have a number of badly checked write() calls. Often we are expecting write() to write exactly the size we requested or fail, this fails to handle interrupts or short writes. Switch to using the new write_in_full(). Otherwise we at a minimum need to check for EINTR and EAGAIN, where this is appropriate use xwrite(). Note, the changes to config handling are much larger and handled in the next patch in the sequence.

Junio C Hamano	85023577a8	simplify inclusion of system header files. This is a mechanical clean-up of the way *.c files include system header files. (1) sources under compat/, platform sha-1 implementations, and xdelta code are exempt from the following rules; (2) the first #include must be "git-compat-util.h" or one of our own header file that includes it first (e.g. config.h, builtin.h, pkt-line.h); (3) system headers that are included in "git-compat-util.h" need not be included in individual C source files. (4) "git-compat-util.h" does not have to include subsystem specific header files (e.g. expat.h). Signed-off-by: Junio C Hamano <junkio@cox.net>	18 years ago
Nicolas Pitre	38fd0721d0	diff-delta: allow reusing of the reference buffer index When a reference buffer is used multiple times then its index can be computed only once and reused multiple times. This patch adds an extra pointer to a pointer argument (from_index) to diff_delta() for this. If from_index is NULL then everything is like before. If from_index is non NULL and from_index is NULL then the index is created and its location stored to from_index. In this case the caller has the responsibility to free the memory pointed to by from_index. If from_index and from_index are non NULL then the index is reused as is. This currently saves about 10% of CPU time to repack the git archive. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Junio C Hamano	86c9523305	Revert "Add deltifier test." This reverts `e726715a52` commit, because reverting diff-delta emptiness change would break this test.	19 years ago
Junio C Hamano	e726715a52	Add deltifier test. This test kicks in only if you built test-delta executable, and makes sure that the basic delta routine is working properly even on empty files. This commit is to make sure we have a test to catch the breakage. The delitifier code is still broken, which will be fixed with the next commit.

Petr Baudis	4d1f119033	[PATCH] Unify usage strings declaration All usage strings are now declared as static const char []. This is carried over from my old git-pb branch. Signed-off-by: Petr Baudis <pasky@ucw.cz> Signed-off-by: Junio C Hamano <junkio@cox.net>	20 years ago
Pavel Roskin	e35f982415	[PATCH] mmap error handling I have reviewed all occurrences of mmap() in git and fixed three types of errors/defects: 1) The result is not checked. 2) The file descriptor is closed if mmap() succeeds, but not when it fails. 3) Various casts applied to -1 are used instead of MAP_FAILED, which is specifically defined to check mmap() return value. [jc: This is a second round of Pavel's patch. He fixed up the problem that close() potentially clobbering the errno from mmap, which the first round had.] Signed-off-by: Pavel Roskin <proski@gnu.org> Signed-off-by: Junio C Hamano <junkio@cox.net>	20 years ago
Junio C Hamano	3c84974207	[PATCH] Fixlets on top of Nico's clean-up. If we prefer 0 as maxsize for diff_delta() to say "unlimited", let's be consistent about it. This patch also fixes type mismatch in a call to get_delta_hdr_size() from packed_delta_info().

Linus Torvalds	75c42d8cc3	Add a "max_size" parameter to diff_delta() Anything that generates a delta to see if two objects are close usually isn't interested in the delta ends up being bigger than some specified size, and this allows us to stop delta generation early when that happens.	20 years ago
Nicolas Pitre	a310d43494	[PATCH] Deltification library work by Nicolas Pitre. This patch adds the basic library functions to create and replay delta information. Also included is a test-delta utility to validate the code. diff-delta was based on LibXDiff written by Davide Libenzi Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Davide Libenzi <davidel@xmailserver.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>	20 years ago
