... and tests 00 through 05 are skipped. I've forgotten to add the skip
form in the tests.

Fixed in the emacs-26 branch, could you pls check?

Best regards, Michael.

Now all of the tests are skipped, is this expected?

Yes, it is for MS Windows. See the definition of
shadow-test-remote-temporary-file-directory.

If you know a temporary directory located on a remote host, you could
run

# env REMOTE_TEMPORARY_FILE_DIRECTORY=/plink:host:/tmp make -C test shadowfile-tests

See the explanation of $REMOTE_TEMPORARY_FILE_DIRECTORY in the
Commentary section of tramp-tests.el. Hmm, maybe I should add a similar
Commentary section to shadowfile-tests.el

Best regards, Michael.

Hmm, I'm not sure I follow.  For the test purposes, you are actually
shadowing the files to the current system, right?  If so, the location
of the temporary directory is known, right?

Or am I missing something?

I do both. I shadow the files to the local system ("/<system-name>:") and
to a remote system ("/method:host:/dir"). For the latter, I mock-up a
remote temporary directory. This is not possible on MS Windows, because
I use "/bin/sh" as connection program to that virtual remote host,
instead of "ssh" or alike.

So you shall declare a usable remote directory via that environment
variable for the MS WIndows case. If you could give me a recipe how to
setup a mock-up method for MS Windows - the better! It has always beaten
me, that the tests do not run out of the box.

The same mechanism is used for filenotify-tests.el and tramp-tests.el.

Best regards, Michael.

I don't see why this would be impossible.  The test suite is run from
the MSYS Bash anyway, and if I start Emacs from there, I get this:

  (executable-find "sh")
    => "d:/usr/MSYS/bin/sh.exe"

(even though the directory where sh.exe leaves is not on the
system-wide PATH on my systems, although most other users do place it
on PATH).  So use executable-find to get the absolute file name of the
shell, instead of a literal "/bin/sh", and I think everything else
should "just work", no?

Does the above fit the bill?  If not, what else is needed for the
mock-up method?

The test suite is also run interactively (that's what I do), so it
cannot be guaranteed that (executable-find "sh") gives a non-nil
result. For this case, there is the REMOTE_TEMPORARY_FILE_DIRECTORY trick.

I will check your proposal next week, when I'm at work. Maybe it works,
but likely I will find only an MS Windows machine which does not offer
any sh.exe - that's Murphy. In that case, I will produce a patch which
you could check.

(All of this shouldn't stop us from closing this bug report, after
confirmation of Glenn)

Thanks, and best regards, Michael.

We could instead ask people to set explicit-shell-file-name.

That's not related directly. REMOTE_TEMPORARY_FILE_DIRECTORY shall be a,
hmm, temporary remote directory. It is useful for testing many
configurations. Before I release a new Tramp version, I run stress tests
for several dozen targets, covering all different connection methods and
configuration winkles, and also different Emacs versions starting with
Emacs 24.

Such a campaign (a script) runs usually longer than 24h, and it never
passes all tests during the first run ...

Using a local sh is interesting only for the default mock-up
method. This is the most boring constellation in my own tests, because
everybody else (and hydra) run those tests already.

Best regards, Michael.

I have tried the following patch. It still runs as expected on my
GNU/Linux machine. Could you pls check for MS Windows?

If it works there, I'll commit to the emacs-26 branch (and similar
patches for filenotify-tests.el and tramp-tests.el).

I ran that in batch mode.  It ran for a while, and then seemed to
hang.  I interrupted it; what ended up in the log file is attached.

Let me know how can I assist you in debugging this.

Well, at least the (executable-find "sh") trick does it. The tests
run. So I will apply it to the three test files I've mentioned
earlier. Emacs-26 or master branch?

Obviously an error I need to fix. I'm wondering, whether shadowfile.el
has run ever on MS Windows. I bed, the same error would happen with the
old implementation.

Thanks for testing.

Emacs-26 is okay in this case, since we are fixing something that is
broken already.

I wouldn't count on it.

Will do. Rather tomorrow, I'll have the chance to test on MS
Windows. Might happen that the other two test files uncover further
errors on MS Windows ...

I could reproduce it with Emacs 26 on MS Windows.

Well, the problem is the syntax of local file names on MS Windows, like
"c:/DOCUME~1/Zaretzky/LOCALS~1/Temp/shadowfile-testsSe3Hgz". shadowfile
uses cluster file names with syntax "/<cluster name>:<local file name>".
If the <local file name> starts with a volume letter, the resulting
string looks like a remote file name, and shadowfile is confused.

Fixing this is not trivial. Is it worth to do it? Again, I doubt that
shadowfile has worked ever on MS Windows; I believe it would be
sufficient to document this restriction.

Best regards, Michael.

Can convert-standard-filename help?  It will convert any colon except
the first one to '!'.

It's up to you.  If fixing is indeed hard, I'd hate to get in the way
of your development of threaded Tramp ;-)

That was also my first idea. But it doesn't help:
"/myname:c:/DOCUME~1/Zaretzky/LOCALS~1/Temp/shadowfile-testsSe3Hgz" is
regarded as remote file name due to the colon after the drive letter. I
would need to change the notation of cluster file names, something
different from "/name:local name". This would introduce much more
incompatibility for all other shadoefile users. And again, I'm convinced
there hasn't been a shadowfile user on MS Windows ever.

I guess best would be to document this restriction. We can still react,
when furious bug reports arrive us. Which I doubt.

I will add (skip-unless (not (memq system-type '(windows-nt ms-dos))))
to all shadowfile-tests tests in the emacs-26 branch.

Well, I have used "\\w+" as hostname syntax. I've changed this to
"[-.[:word:]]+", could you pls check whether this works?

Pushed to the emacs-26 branch.

Best regards, Michael.

Works for me thanks. Separately, please note that
shadow-test08-shadow-todo has aborted on hydra.nixos.org ever since it
was first added.

No further information, hmm. I've made a small compatibility change in
shadowfile.el, which might fix it, or not. And I've instrumented
shadow-test08-shadow-todo to be more chatty. Let's see.

Best regards, Michael.

After weeks of hunting, I could trap it finally. Fixed in master, all
shadowfile-tests tests pass successfully on hydra.

Since I've backported the fix to the emacs-26 branch, I'm closing this
bug for Emacs 26.2.

Best regards, Michael.

Quite a saga, well done! :)
