Description (last modified by )
POSIX https://pubs.opengroup.org/onlinepubs/9799919799/functions/rename.html specifies that the renameat() function "shall fail" with error code EBADF if "The old argument does not specify an absolute path and the oldfd argument is neither AT_FDCWD nor a valid file descriptor open for reading or searching, or the new argument does not specify an absolute path and the newfd argument is neither AT_FDCWD nor a valid file descriptor open for reading or searching."
This does not work in Haiku hrev57823 (from 2024-07-15): in one case, it behaves as if AT_FDCWD had been specified; in the other case, it fails with error code ENOENT instead.
How to reproduce: Compile and run the attached test program.
gcc -Wall foo.c ./a.out
Expected output:
ret = -1, errno == EBADF ret = -1, errno == EBADF OK
Actual output if a file 'foo' does not exist in the current directory:
ret = -1, errno == No such file or directory ret = -1, errno == No such file or directory a.out: foo.c:41:main: !fail Kill Thread
Actual output if a file 'foo' does exist in the current directory:
ret = 0 ret = -1, errno == No such file or directory a.out: foo.c:41:main: !fail Kill Thread
test case foo.c
