Eric Blake 70a72e0f 2011-04-08T10:15:54 nonblocking: provide O_NONBLOCK for mingw Mingw is the only known platform that lacks O_NONBLOCK (possibly via the alternate spelling O_NDELAY). But mingw also lacks any files where open() needs to enforce non-blocking behavior, and lacks openat(), so it is relatively simple to provide a non-zero flag. A future patches will make use of O_NONBLOCK for pipe2. * modules/nonblocking (Depends-on): Add open. (configure.ac): Set new witness macro. * m4/fcntl_h.m4 (gl_FCNTL_H_DEFAULTS): Provide default for it. * modules/fcntl-h (Makefile.am): Substitute it. * lib/fcntl.in.h (O_NONBLOCK): Guarantee non-zero definition when nonblocking module is in use. * lib/nonblocking.c: Adjust portability test. * lib/open.c (open): Don't let native open see gnulib flag. * tests/test-fcntl-h.c (main): Enhance test. * tests/test-open.h (test_open): Likewise. * doc/posix-headers/fcntl.texi (fcntl.h): Document the replacement.

Also, O_EXEC is now defined to be O_RDONLY if O_EXEC is not defined. Similarly for O_SEARCH; this last was already true, but not documented. * lib/fcntl.in.h (O_CLOEXEC): Define to 0 if not defined. * lib/dup-safer-flag.c (O_CLOEXEC): Remove now-useless #define. * lib/dup3.c, lib/pipe2.c, tests/test-dup-safer.c, tests/test-fcntl.c: Likewise. * lib/popen-safer.c (open_noinherit): Check whether O_CLOEXEC is zero, not whether it is defined. * tests/test-dup3.c, tests/test-pipe2.c (main): Likewise. * lib/progreloc.c (find_executable): Use O_EXEC rather than O_RDONLY. * lib/open.c (open): Check for O_SEARCH as well as for O_RDONLY.
