[Git][cmucl/cmucl][issue-125-unix-stat-wrong] Don't use dev_t and friends in stat interface definition.

Raymond Toy pushed to branch issue-125-unix-stat-wrong at cmucl / cmucl Commits: b726c5a4 by Raymond Toy at 2022-08-03T19:01:31-07:00 Don't use dev_t and friends in stat interface definition. To simplify things, don't use dev_t and friends in the C interface. Instead, use the largest integer type that any OS would want to use. So dev_t becomes u_int64_t because Linux can return 64-bit integers here. This would work just fine for macos which uses 32-bit integers.

Raymond Toy pushed to branch issue-125-unix-stat-wrong at cmucl / cmucl Commits: 55140c71 by Raymond Toy at 2022-08-03T09:52:06-07:00 64-bit support and clean up times In unix.c define _LARGEFILE_SOURCE and _FILE_OFFSET_BITS so that we can the 64-bit versions of stat and friends. Also, for compatibility, we don't return a struct timespec, but a long for the number of seconds. We ignore the nanosec part. In unix.lisp, change the definition of dev-t on linux to be u-int64-t since it seems we support the 64-bit integer type. - - - - - 97f6a14c by Raymond Toy at 2022-08-03T10:00:45-07:00 Use time_t/time-t instead of long For the time fields, use time_t on the C side and time-t on the Lisp side. - - - - - 8dd3f6ae by Raymond Toy at 2022-08-03T11:26:29-07:00 Simplify implementation of unix-stat and friends Since the body of unix-stat and friends are almost identical and only differ in the arg and type of the first arg to stat, we use a macro to handle the call to stat. - - - - - 2 changed files: - src/code/unix.lisp - src/lisp/unix.c Changes: ===================================== src/code/unix.lisp ===================================== @@ -74,8 +74,7 @@ (def-alien-type dev-t #-(or alpha svr4 bsd linux) short - #+(and linux (not amd64)) uquad-t - #+(and linux amd64) u-int64-t + #+linux u-int64-t #+netbsd u-int64-t #+alpha int #+(and (not linux) (not netbsd) (or bsd svr4)) unsigned-long) @@ -1573,207 +1572,96 @@ ;; ;; This should be updated so that all OSes do this. #+linux -(progn -(defun unix-stat (name) - _N"Unix-stat retrieves information about the specified +(macrolet + ((call-stat (c-func-name first-arg-type first-arg) + ;; Call the stat function named C-FUNC-NAME.
