Shawn O. Pearce	dc49cd769b	Cast 64 bit off_t to 32 bit size_t 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.

Johannes Schindelin	7cab5883ff	move read_mmfile() into xdiff-interface read_file() was a useful function if you want to work with the xdiff stuff, so it was renamed and put into a more central place.

Jonas Fonseca	83572c1a91	Use xrealloc instead of realloc Change places that use realloc, without a proper error path, to instead use xrealloc. Drop an erroneous error path in the daemon code that used errno in the die message in favour of the simpler xrealloc.

Junio C Hamano	d9ea73e056	combine-diff: refactor built-in xdiff interface. This refactors the line-by-line callback mechanism used in combine-diff so that other programs can reuse it more easily. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
