Subject: 27.0.50; Symlinks recognized as dirs
Date: Sat, 28 Apr 2018 21:44:38 +0100

Reproduction:

0. Get a Mac
1. Download the most recent Emacs 26 nightly from 
https://emacsformacosx.com/builds
2. Symlink a file in a dir to another file in another dir
3. C-x C-f some prefix to the symlink
4. TAB for completion
5. Completion completed the path with an extra /
6. RET
7. Emacs opens up the dir as a new file in a fundamental mode buffer

Expectation:
Completion should not complete the symlink as a dir, opening the dir as
a regular file instead of dired should also not be possible.

Correction:

This bug was submitted from a Emacs 27 nightly build, but the same
problem occurs in Emacs 26 RC1 also.

I could have sworn we fixed this, but I can’t find the previous bug
report.

FWIW, I can’t reproduce it.

Looks similar to Bug#28865 "broken symlink behaviour in read-file-name
on OS X (High Sierra)".

That’s it exactly. Thanks Noam!

With further testing I’ve discovered that although I can’t replicate
it with my locally built version, I can with an emacsformacosx.com
build.

I guess that means either Paul’s fix doesn’t work on macOS 10.9, or
David needs to update something in his build tree.

Possibly the Gnulib workaround for the macOS faccessat bug does not work 
in older macOS versions. For example, the Gnulib workaround calls the 
function 'access' on platforms lacking faccessat, and faccessat is 
missing and 'access ("foo/", F_OK)' ignores the trailing slash in older 
macOS versions, then that could explain the problem.

Suppose my guess is right. Then, if this problem occurs because the 
emacsformacosx.com build is for OS X 10.9 or earlier, then a simple fix 
is to have emacsformacosx.com build for OS X 10.10 or later, because 
Emacs can't reasonably support OS versions that Apple itself does not 
support <https://lists.gnu.org/r/emacs-devel/2018-03/msg00798.html>. On 
the other hand, if the problem occurs on OS X 10.10 or later, then 
someone should hack on the Gnulib workaround so as to port the 
workaround to OS X 10.10. I can volunteer to do the hacking in my spare 
time, but I don't have easy access to OS X 10.10 so someone else would 
need to test it.

For the record, currently I build on 10.6, 10.8 and 10.9. I'm very very
close to killing the 10.6 build.

This is very easy to do, I mostly haven't already because I didn't see
any compelling reason to build on later machines (I'm not aware of any
10.10-10.13 dependent features the same way that say full screen mode
only works in 10.9 and later).

I have a 10.10 VM and could probably test it. I can't promise I'll be
super available though.

Thanks for the info. When you have a moment could you please try 
building on OS X 10.10 and then testing the result? I assume OS X 10.10 
has a file /etc/passwd so you could run something like this:

ln -s /etc/passwd .
src/emacs -Q -batch -eval '(message "%S" (file-name-completion "pass" "."))'

This should output "passwd" (assuming that the build directory has no 
other entry beginning with "pass"), but if the bug I'm hypothesizing is 
triggered, than it will output "passwd/".

One more thing. This reminds me of Bug#30350, so if this new bug still 
occurs under OS X 10.10 please try the attached patch. If this works 
around the OS X 10.10 bug I can polish it up and install it properly 
into Emacs. Thanks.

Hi Paul,

I built from 60ff8101449eea3a5ca4961299501efd83d011bd.

$ sw_vers
ProductName:	Mac OS X
ProductVersion:	10.10.5
BuildVersion:	14F2511
$ src/emacs -Q -batch -eval '(message "%S" (file-name-completion "pass"
"."))'
"passwd"

Since this doesn't seem to match your hypothesis, do you still want me
to try it with the "/./" patch you sent?

-David

Thanks for checking that it works on OS X 10.10.

I wouldn't bother. If the bug is fixed in OS X 10.10 and Apple itself 
doesn't support older systems, then we shouldn't need to worry about 
this bug upstream. I suggest building Emacs for OS X 10.10, recommending 
10.10 (or later) builds to users, and warning that there may be glitches 
if people use builds for older systems. To document this I installed the 
attached into the emacs-26 branch.

Ok. So I'll start building on at least 10.10. I think Alan made some
changes so that we can actually build on the latest OS and set it so
it'll run on older versions and maybe I start doing that soon since it
should vastly simplify the build process.

If that works it'd be great. Although I'd be surprised if it fixes this 
problem, macOS is full of surprises....

Let's see if I read this discussion correctly:

1. We don't support macOS older than 10.10.  (Perhaps that should be
   10.11 once 10.15 is released in October?)

2. This bug doesn't manifest itself on macOS 10.10 or later.

So is there anything left to do here?  If the above two points are true,
then I guess this should be closed as wontfix?

As far as I’m aware we support back to 10.6. Apple only support the
three most recent versions, so currently 10.12, 10.13 and 10.14.

There has been some discussion around dropping support for older macOS
versions, but we still have a number of active users and Emacs
developers running 10.6.

Interesting.  In the context of this bug, and given Paul Eggert's
comments earlier, do we still want to fix this?  It's been documented
in etc/PROBLEMS and is fixed by an upgrade to 10.10.

IMHO, this bug is so minor that it's not worth spending time on at
this point.  Does anyone object to closing this as wontfix?  Is that
against our policy since we still technically support 10.6 through
10.9?

Best regards,

No, and that sounds like the right thing to do. Tagged wontfix and closing.
