Hi @barracuda156,

Thanks for your report! Unfortunately, I do not have access to a PPC for debugging. Hence, it would be interesting for me to know what

bettermc::copy2shm(1:10, "/short_name")

and

bettermc::copy2shm(1:10, "/this_is_a_too_long_name_for_macos")

return on your system. Thanks!

[barracuda156]

[akersting]

@barracuda156 Thanks! This looks correct.

Admittedly, I am a bit clueless. Your output shows that POSIX shared memory is generally supported on your system. However, man shm_unlink on my Intel Mac states

ERRORS
The shm_unlink() succeeds unless:

 [EACCES]           Permission is denied to be remove the object.

 [ENAMETOOLONG]     name exceeded the name size limit.  This is currently
                    PSHMNAMLEN characters (defined in <sys/posix_shm.h>),
                    but this may change in the future.

 [ENOENT]           The named object does not exist.

(cf. also https://developer.apple.com/library/archive/documentation/System/Conceptual/ManPages_iPhoneOS/man2/shm_unlink.2.html, which is actually for iOS, or the man pages on Linux)

So, [EINVAL] (Invalid Argument) is not a legitimate errno to be set by shm_unlink.

Could you once check man shm_unlink on your system if it mentions [EINVAL]?

On another, but somewhat related issue: The last test failure you shared is

'semv_open(-1)' did not throw an error

Again, behavior on your system does not match documented behavior. According to man semctl (which is called by semv_open()), setting the value of a semaphore to -1 should fail with [ERANGE].

[barracuda156]

Apparently no:

SHM_UNLINK(2)                 System Calls Manual                SHM_UNLINK(2)

NAME
     shm_unlink - remove shared memory object

SYNOPSIS
     #include <sys/mman.h>

     int
     shm_unlink(const char *name);

DESCRIPTION
     The shm_unlink() function disassociates the shared memory object
     specified by name from that name.  The resources associated with the
     shared memory object remain intact until the last file descriptor
     reference is removed, e.g., by close(2) or munmap(2), at which point the
     resources are reclaimed (if no references exist at the time of the call
     to shm_unlink(), the resources are reclaimed immediately).  The name can
     only be reused when it is bound to a new shared memory object with a call
     to shm_open(2) with the O_CREAT flag.

RETURN VALUES
     Upon successful completion, a value of 0 is returned.  Otherwise, a value
     of -1 is returned and errno is set to indicate the error, and the named
     shared memory object will remain unchanged.

ERRORS
     The shm_unlink() succeeds unless:

     [EACCES]           Permission is denied to be remove the object.

     [ENAMETOOLONG]     name exceeded SHM_NAME_MAX characters.

     [ENOENT]           The named object does not exist.

SEE ALSO
     close(2), mmap(2), munmap(2), shm_open(2), shmat(2), shmctl(2)

HISTORY
     shm_open() is specified in the POSIX Realtime Extension
     (1003.1b-1993/1003.1i-1995).
