Cast 64 bit off_t to 32 bit size_t

2007-03-07T19:15:26Z

Some systems have sizeof(off_t) == 8 while sizeof(size_t) == 4. This implies that we are able to access and work on files whose maximum length is around 2^63-1 bytes, but we can only malloc or mmap somewhat less than 2^32-1 bytes of memory. On such a system an implicit conversion of off_t to size_t can cause the size_t to wrap, resulting in unexpected and exciting behavior. Right now we are working around all gcc warnings generated by the -Wshorten-64-to-32 option by passing the off_t through xsize_t(). In the future we should make xsize_t on such problematic platforms detect the wrapping and die if such a file is accessed. Signed-off-by: Shawn O. Pearce Signed-off-by: Junio C Hamano

simplify inclusion of system header files.

2006-12-20T17:51:35Z

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

Remove all void-pointer arithmetic.

2006-06-20T08:59:46Z

ANSI C99 doesn't allow void-pointer arithmetic. This patch fixes this in various ways. Usually the strategy that required the least changes was used. Signed-off-by: Florian Forster Signed-off-by: Junio C Hamano

avoid asking ?alloc() for zero bytes.

2005-12-27T01:23:59Z

Avoid asking for zero bytes when that change simplifies overall logic. Later we would change the wrapper to ask for 1 byte on platforms that return NULL for zero byte request. Signed-off-by: Junio C Hamano

[PATCH] mmap error handling

2005-07-30T00:21:48Z

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 Signed-off-by: Junio C Hamano

[PATCH] Add -O option to diff-* brothers.

2005-05-31T01:10:46Z

A new diffcore filter diffcore-order is introduced. This takes a text file each of whose line is a shell glob pattern. Patches that match a glob pattern on an earlier line in the file are output before patches that match a later line, and patches that do not match any glob pattern are output last. A typical orderfile for git project probably should look like this: README Makefile Documentation *.h *.c Signed-off-by: Junio C Hamano Signed-off-by: Linus Torvalds
