David Drysdale	f1bcfa1122	api: Allow injection of user-specified malloc/free functions Add a new ares_library_init_mem() initialization function for the library which allows the library user to specify their own malloc, realloc & free equivalents for use library-wide. Store these function pointers in library-wide global variables, defaulting to libc's malloc(), realloc() and free(). Change all calls to malloc, realloc and free to use the function pointer instead. Also ensure that ares_strdup() is always available (even if the local environment includes strdup(3)), and change the library code to always use it. Convert calls to calloc() to use ares_malloc() + memset	9 years ago
David Drysdale	87ff25049c	Mark unhittable lines Add comments for the benefit of the lcov tool, marking lines that cannot be hit. Typically these are fall-back protection arms that are already covered by earlier checks, and so it's not worth taking out the unhittable code (in case someone changes the code between the two places in future).	9 years ago
David Drysdale	02e1f7f9af	ares_expand_name: check for valid bits in label length The top two bits of the label length indicate whether this is a label length (00) or an index to a name elsewhere in the message (11). RFC1035 4.1.4 says that the other possible values for the top two bits (01, 10) are reserved for future use.	9 years ago

Daniel Stenberg	8362245c42	- Phil Blundell added the internal function ares__expand_name_for_response() that is now used by the ares_parse_*_reply() functions instead of the ares_expand_name() simply to easier return ARES_EBADRESP for the cases where the name expansion fails as in responses that really isn't expected.	16 years ago

Daniel Stenberg	ae75ee1423	William Ahern: I'm not quite sure how this was happening, but I've been seeing PTR queries which seem to return empty responses. At least, they were empty when calling ares_expand_name() on the record. Here's a patch which guarantees to NUL-terminate the expanded name. The old behavior failed to NUL-terminate if len was 0, and this was causing strlen() to run past the end of the buffer after calling ares_expand_name() and getting ARES_SUCCESS as the return value. If q is not greater than s then it's equal and s is always allocated with at least one byte.	20 years ago

Daniel Stenberg	d5f3636a52	- Fixed a few variable return types for some system calls. Made configure check for ssize_t to make it possible to use that when receiving the send() error code. This is necessary to prevent compiler warnings on some systems. - Made configure create config.h, and all source files now include setup.h that might include the proper config.h (or a handicrafted alternative). - Switched to 'ares_socket_t' type for sockets in ares, since Windows don't use 'int' for that. - automake-ified and libool-ified c-ares. Now it builds libcares as a shared lib on most platforms if wanted. (This bloated the size of the release archive with another 200K!) - Makefile.am now uses Makefile.inc for the c sources, h headers and man pages, to make it easier for other makefiles to use the exact same set of files. - Adjusted 'maketgz' to use the new automake magic when building distribution archives.	21 years ago
Daniel Stenberg	961876c001	make ares_expand_name() take a long * instead of an int *, since we do pointer arithmetic (ptr1 - ptr2) and to do that properly on 64bit we need long	21 years ago
