as POSIX 2008 requires. It also matches now how our 'ls' works for years.
b) Remove comment expressed 2 fears:
1) One just simple describe how strcoll() works in _any_ context,
not for directories only. Are we plan to remove strcoll() from everything
just because it is little more complex than strcmp()? I doubt, and
directories give nothing different here. Moreover, strcoll() used
in 'ls' for years and nobody complaints yet.
2) Plain wrong statement about undefined strcoll() behaviour. strcoll()
always gives predictable results, falling back to strcmp() on any
trouble, see strcoll(3).
No objections from -current list discussion.
to obtain an initial estimate of the array length needed to store all
the directory entries. Although BSD has historically guaranteed that
st_size is the size of the directory file, POSIX does not, and more to
the point, some recent filesystems such as ZFS use st_size to mean
something else.
The fix is to not stat the directory at all, set the initial
array size to 32 entries, and realloc it in powers of 2 if that
proves insufficient.

- Move CSRG IDs into __SCCSID().
- When a file has been copied, consistently use 'From: <tag>' for strings
referencing the version of the source file copied from in the license
block comment.
- Some of the 'From:' tags were using $FreeBSD$ that was being expanded on
each checkout. Fix those to hardcode the FreeBSD tag from the file that
was copied at the time of the copy.
- When multiple strings are present list them in "chronological" order,
so CSRG (__SCCSID) before FreeBSD (__FBSDID). If a file came from
OtherBSD and contains a CSRG ID from the OtherBSD file, use the order
CSRG -> OtherBSD -> FreeBSD.

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

Mainly focus on files that use BSD 3-Clause license.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
Use existing HAVE_OPENDIR define to determine if a generic
implementation should be provided. Cygwin for example has its own
implementation of opendir() and dirfd().

Use O_RDONLY since you are not supposed to write to a directory.
Use O_DIRECTORY as mandated by POSIX (The Open Group Base Specifications
Issue 7, 2018 edition IEEE Std 1003.1-2017):
"If the type DIR is implemented using a file descriptor, the descriptor
shall be obtained as if the O_DIRECTORY flag was passed to open()."
Use O_CLOEXEC as mandated by POSIX:
"When a file descriptor is used to implement the directory stream, it
behaves as if the FD_CLOEXEC had been set for the file descriptor."
Drop the fcntl() call in favour of O_CLOEXEC.

Newlib build system defines __SINGLE_THREAD__ to allow concurrency code
to be only compiled when newlib is configured for multithread. One such
example are locks which become useless in single thread mode. Although
most static locks are indeed guarded by !defined(__SINGLE_THREAD__),
some are not.
This commit adds these missing guards to __dd_hash_mutex,
__atexit_recursive_mutex, __at_quick_exit_mutex and __arc4random_mutex.
It also makes sure locking macros in lock.h are noop in single thread
mode.
In preparation for the patch that would allow retargeting of locking
routines, rename all lock objects to follow this pattern:
"__<name>_[recursive_]mutex".
Following locks were renamed:
__dd_hash_lock -> __dd_hash_mutex
__sfp_lock -> __sfp_recursive_mutex
__sinit_lock -> __sinit_recursive_mutex
__atexit_lock -> __atexit_recursive_mutex
_arc4random_mutex -> __arc4random_mutex
__env_lock_object -> __env_recursive_mutex
__malloc_lock_object -> __malloc_recursive_mutex
__atexit_mutex -> __at_quick_exit_mutex
__tz_lock_object -> __tz_mutex
Hi,
With the patch to allow newlib's locking routine to be retargeted currently
under discussion, we need to start thinking of locks as part of newlib's ABI
since newlib depends on specific names being provided by the OS. This patch
renames 2 locks so that they follow the same naming convention as other locks.
It needs to be applied before the retargeting patch, while locks are still an
internal consideration.
Newlib builds successfully with this change.
Ok for master branch?
Best regards,
Thomas
These source files have makedoc markup, but aren't listed to be chewed by
makedoc. I am assuming that is accidental.
Future work: Note that stdio/fseeko.c, stdio/ftello.c and common/s_isnand.c have
makedoc markup, but duplicate stdio/fseek.c, stdio/ftell.c and common/s_isnan.c
respectively.
