In {encode,decode}-coding-string, the NOCOPY parameter had the
opposite effect to what was intended and documented. This 18 year old

* test/lisp/net/tramp-tests.el (tramp-test29-start-file-process)
(tramp-test30-make-process, tramp-test33-environment-variables):
Expect failure on hydra.nixos.org, since March 29 Tramp cache changes.
Make Math-num-integerp return false for nil, following Math-integerp
which was changed in the bignum reform. This fixes a crash in
calc-graph-fast.
Reported by Narendra Joshi.
* lisp/calc/calc-macs.el (Math-num-integerp): Not true for nil.
* test/lisp/calc/calc-tests.el (calc-Math-integerp): New tests.
These changes let the code compile and produce a valid DLL, but the
test hangs. It looks like the hang is in Fdelete_process, when it
closes one of the descriptors of the pipe process.
In addition, this use of the pipe process cannot currently work
on MS-Windows, since make-pipe-process doesn't set up the reader
thread to read from the Emacs's side of the pipe, so the select
emulation doesn't know there's stuff to read from that pipe.
* test/data/emacs-module/mod-test.c [WINDOWSNT]: Include
windows.h.
(ALIGN_STACK) [!__x86_64__]: Define for 32-bit builds.
(sleep_for_half_second): New function.
(write_to_pipe): Declare return type differently for WINDOWSNT.
Call sleep_for_half_second.
(Fmod_test_async_pipe) [WINDOWSNT]: Use _beginthread as substitute
for pthread_create.
(invalid_finalizer): Replace non_ASCII character in a comment.
* test/src/emacs-module-tests.el (module/async-pipe): Skip on
MS-Windows, as the test fails and then hangs.
A common complaint about the module API is that modules can't
communicate asynchronously with Emacs. While it isn't possible to
call arbitrary Emacs functions asynchronously, writing to a pipe
should always be fine and is a pretty low-hanging fruit.
This patch implements a function that adapts an existing pipe
process. That way, users can use familiar tools like process filters
or 'accept-process-output'.
* src/module-env-28.h: Add 'open_channel' module function.
* src/emacs-module.c (module_open_channel): Provide definition for
'open_channel'.

This is a companion to the recent set-file-modes patch.
It adds support for a ‘nofollow’ flag to set-file-times (Bug#39773).
Like the set-file-modes patch, it needs work in the w32 port.

* src/fileio.c (Fcopy_file): Use futimens instead of set_file_times,
as it’s simpler and is a POSIX API.
* src/sysdep.c (set_file_times): Move from here ...
* src/w32.c (set_file_times): ... to here, and make it static,
since it is now used only in w32.c. Presumably w32.c should also
add support for futimens and utimensat (the POSIX APIs, which
Emacs now uses) and it can remove fdutimens (the Gnulib API,
which Emacs no longer uses).
