test: pipe_overlong_path fails on AIX

[abmusse]

• Version: Current v1.x branch
• Platform: AIX

Discovered this failure while running the CI for a pull request:

Ref: #4229

https://ci.nodejs.org/job/libuv-test-commit-aix/nodes=aix72-ppc64/2279/console

not ok 199 - pipe_overlong_path
# exit code 393222
# Output from process `pipe_overlong_path`:
# Assertion failed in test/test-pipe-bind-error.c on line 175: `UV_EINVAL == uv_pipe_bind2(&pipe, path, sizeof(path), UV_PIPE_NO_TRUNCATE)` (-22 == -86)

libuv/test/test-pipe-bind-error.c

Line 175 in 6be130e

ASSERT_EQ(UV_EINVAL,

Looks like errno 86 maps to ENAMETOOLONG on AIX.

Looks like this passes as expected on IBM i:

What is the size of struct sockaddr_un.sun_path on AIX?

What is the size of struct sockaddr_un.sun_path on AIX?

Looks like its set to 1024 or 1023

From: /usr/include/sys/un.h

#if defined(COMPAT_43) && !defined(_KERNEL)
struct  sockaddr_un {
        ushort_t        sun_family;     /* AF_UNIX */
        char        sun_path[1024]; /* changed from 104 to PATH_MAX to support long user names. This value should be ch
anged manually if PATH_MAX changes in future */
};
#else
struct  sockaddr_un {
        uchar_t     sun_len;            /* sockaddr len including null */
        sa_family_t sun_family;         /* AF_UNIX */
        char        sun_path[1023]; /* changed from 104 to PATH_MAX to support long user names. This value should be ch
anged manually if PATH_MAX changes in future */
};
#endif /* COMPAT_43 && !_KERNEL */
