What changed:
|
|
-------------
|
|
|
|
- Allow symlinks to be opened with O_PATH | O_NOFOLLOW.
|
|
|
|
- Allow the pathname argument to readlinkat(2) to be an empty string,
|
|
provided the dirfd argument refers to a symlink opened with
|
|
O_PATH | O_NOFOLLOW. The readlinkat call then operates on that
|
|
symlink.
|
|
|
|
- Support the Linux-specific AT_EMPTY_PATH flag for fchownat(2) and
|
|
fstatat(2).
|
|
|
|
- Allow AF_LOCAL sockets to be opened with O_PATH.
|
|
|
|
- <signal.h>: New macro _NSIG replacing NSIG. NSIG is now only
|
|
visible to MISC builds, as on Linux.
|
|
|
|
- The new locale modifier @cjksingle allows enforcing of single-width
|
|
character property for usually double-widthed characters. This will
|
|
be supported by upcoming mintty releases. For the reasoning, see
|
|
https://gitlab.freedesktop.org/terminal-wg/specifications/issues/9.
