[PATCH v3 0/2] Misc Patches

[Joel Sherrill]

Hi

This patch series is small and the patches are independent.
The only common factor is that they fix issues recently encountered
in the RTEMS Community.

0001 - Add extern "C" to devctl.h
0002 - Convert symlinks to real files for x86_64 and i386 fenv

Now of this is particularly complicated but hopefully the explanations
are adequate in the commit message.

Thanks.

[PATCH v3 2/2] x86_64/i386 fenv: Replace symlink with include fenv_stub.c

[Joel Sherrill]

Having symlinks for these files led to an issue reported to the
RTEMS Project that showed up on MSYS2. Per the report we received,
there are no such things as links on Windows, it is a copy of the
file and if it does not exist it has to fail. The working all depends
on the order the tar file is built. If the links appear in the tar file
before the source exists, it cannot copy the file.

The solution in this patch is to convert the files that are symbolic
links into simple files which include the file they were linked to.
This should be more portable and avoids the symbolinc link problem.

[PATCH v3 1/2] newlib/libc/include/devctl.h: Add extern "C" wrapper

Adding this was necessary to allow posix_devctl() from C++.

Hey Joel,

the patch itself is fine, but I'm puzzeling over the commit message.

MSYS2 is a Cygwin clone which understands any kind of Cygwin symlink,
an invention from way back when Windows really didn't have symlinks.

NTFS has symlinks since Windows Vista, about 2007.

Isn't that just somebody using an inadequate tool here?  Do you have a
pointer to a bugzilla/github/whatever issue clarifying the actual
problem?

That was the end result of the investigation into the user's issue. I had
to be
pinged privately to even notice that my fenv addition of symlinks triggered
the
failure. It just wasn't obvious at first to me. It was hard to see how the
fenv patch
could trigger this.

My conclusion is that avoiding symlinks in source distributions falls into
the
same rule bucket as not using capitalization to distinguish files in the
same
directory. Works almost everywhere not not quite. Just like we used to avoid
long file names.

Yeah. It is an issue with tar. Apparently you can't create symlinks
to non-existent files at least with bsdtar. If the link is in the tar file
before
the real file, it fails to create the file. Maybe GNU tar covers this
up.

Here is the thread. It is a few messages in before investigation shows it
is a tar file issue.

https://lists.rtems.org/pipermail/devel/2020-February/057184.html

The RTEMS ticket is here:

https://devel.rtems.org/ticket/3868

I know this is an odd one.

In that case I'd like to change the commit message to something along
these lines:

---
Having symlinks for these files led to an issue reported to the RTEMS
Project that showed up using some tar for native Windows to unpack the
newlib sources.  It creates symlinks in the tar file as copies of the
files the symlinks point to.  If the links appear in the tar file before 
the source exists, it cannot copy the file.

The solution in this patch is to convert the files that are symbolic
links into simple files which include the file they were linked to.
This should be more portable and avoids the symbolinc link problem.
---

This doesn't point to MSYS2 or "recet" Windows versions as the culprit.


That ok with you?

Corinna
