Hi!
Emacs 24.2 on Windows doesn't expand remote file names:
(expand-file-name "/ssh:user@host:/")
"/ssh:user@host:/"
While Emacs 24.3.1 does:
(expand-file-name "/ssh:user@host:/")
"/ssh:user@host:c:/"
And this makes Tramp to fail (it can't find proper ls command, but
that's a side effect).
It's probably affects only the Windows build, because cygwin build of
emacs 24.3.1 doesn't produce the same fault.
I start Emacs from a Cygwin terminal (but not the Cygwin version of
Emacs). Just for your information.

the From: line contains a valid email address. After a delay of up
to one day, you should receive an acknowledgment at that address.
Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.
Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug. If you can, give a recipe
starting from `emacs -Q':
If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
`bt full' and `xbacktrace'.

This is due to some change in Tramp, specifically in
tramp-sh-file-name-handler: it returned "/ssh:user@host:/" in 24.2,
but "/ssh:user@host:c:/" in 24.3. Michael, could you please take a
look?

I can easily reproduce this from the cmd window as well.

This is competely strange. In `tramp-sh-handle-expand-file-name', there
is the following code at the very end:
(let ((directory-sep-char ?/)
(default-directory (tramp-compat-temporary-file-directory)))
(tramp-make-tramp-file-name
method user host
(tramp-drop-volume-letter
(tramp-run-real-handler
'expand-file-name (list localname)))
hop)))))
In Emacs 24.3, `tramp-drop-volume-letter' is not executed:
| | | | 5 -> tramp-run-real-handler: operation=expand-file-name args=("/root/")
| | | | 5 <- tramp-run-real-handler: "c:/root/"
| | | | 5 -> tramp-make-tramp-file-name: method="plink" user=nil host="ford" localname="c:/root/" hop=nil
| | | | 5 <- tramp-make-tramp-file-name: "/plink:ford:c:/root/"
When I use Emacs 24.3.50, the latest snapshot, that function is
executed:
| | | | 5 -> (tramp-run-real-handler expand-file-name ("/root/"))
| | | | 5 <- tramp-run-real-handler: "c:/root/"
| | | | 5 -> (tramp-drop-volume-letter "c:/root/")
| | | | 5 <- tramp-drop-volume-letter: "/root/"
| | | | 5 -> (tramp-make-tramp-file-name "plink" nil "ford" "/root/" nil)
| | | | 5 <- tramp-make-tramp-file-name: "/plink:ford:/root/"
I have no idea, what prevents `tramp-drop-volume-letter' to be called.
If you want to reproduce my test, I have setup the traces like this:
(require 'tramp)
(require 'trace)
(dolist (elt (all-completions "tramp-" obarray 'functionp))
(trace-function-background (intern elt)))
(expand-file-name "/plink:ford:")
Best regards, Michael.

Since tramp-drop-volume-letter is not a function, it's a defalias, so
maybe it somehow doesn't get registered in the trace?
Or maybe it somehow takes the 'identity route?

No.
(tramp-drop-volume-letter "c:/root/")
=> "/root/"

My crystal ball says that your 24.3.50 snapshot was bootstrapped on
MS-Windows, or at least Tramp was compiled on Windows. See below.

That's not the same, because the call to tramp-drop-volume-letter in
tramp-sh-handle-expand-file-name could still be expanded to 'identity'
(= nothing) by the byte compiler when tramp-sh.elc was compiled. And
indeed, disassembling tramp-sh-handle-expand-file-name from
tramp-sh.elc provided in the Emacs 24.3 tarball shows this:
336 varbind default-directory
337 varbind directory-sep-char
339 constant tramp-make-tramp-file-name
340 varref method
341 varref user
342 varref host
344 constant tramp-run-real-handler
345 constant expand-file-name
346 varref localname
348 list1
349 call 2
350 varref hop
352 call 5
353 unbind 8
355 return
"Look, ma: no tramp-drop-volume-letter!"
If I now byte-compile tramp-sh.el on MS-Windows, I get this
disassembly:
336 varbind default-directory
337 varbind directory-sep-char
339 constant tramp-make-tramp-file-name
340 varref method
341 varref user
342 varref host
344 constant tramp-drop-volume-letter <<<<<<<<<<<<<<<<<<<<<<<<
345 constant tramp-run-real-handler
346 constant expand-file-name
347 varref localname
349 list1
350 call 2
351 call 1
352 varref hop
354 call 5
355 unbind 8
357 return
(And, btw, the .elc file I get is 50KB smaller than the one in the
tarball -- why?)
If I compile tramp-sh.el on GNU/Linux with the latest trunk, I still
don't see tramp-drop-volume-letter in the disassembly of
tramp-sh-handle-expand-file-name. So the problem is still there in
the current trunk. By contrast, if I compile tramp-sh.el with Emacs
24.2, I do see the call to tramp-drop-volume-letter in the
disassembly.
So, somehow, compiling tramp-sh.el on Unix replaces the call to
tramp-drop-volume-letter with nothing. Perhaps the condition, viz.
(defalias 'tramp-drop-volume-letter
(if (memq system-type '(cygwin windows-nt)) <<<<<<<<<<<<<<<<<<<
(lambda (name)
"Cut off unnecessary drive letter from file NAME.
The functions `tramp-*-handle-expand-file-name' call `expand-file-name'
locally on a remote file name. When the local system is a W32 system
but the remote system is Unix, this introduces a superfluous drive
letter into the file name. This function removes it."
(save-match-data
(if (string-match "\\`[a-zA-Z]:/" name)
(replace-match "/" nil t name)
name)))
'identity))
is expanded at byte-compile time, instead of at run time?
And I guess whatever has this effect was introduced between the
release of 24.2 and 24.3 (which was the trunk until 24.2 release).

Yes, that is intended. tramp-drop-volume-letter is not needed on GNU/Linux.

Looks like this, yes.

Yes, it was changed in bzr commit #105625.
Does this mean, this declaration requests Tramp to be compiled on MS
Windows? I have used the official distribution from
<http://ftp.gnu.org/gnu/emacs/windows/>. It reports

We shall repackage Emacs 24.3 for MS Windows then. Other packages might
suffer from the same problem.

??? But byte-compiled files are supposed to be platform-independent.
The release tarball includes all of the *.elc files, which were
compiled on Unix when the release was tarred, and they are not
recompiled when Emacs is built on Windows (or on any other platform).
Now you seem to be saying that all the *.elc files need to be compiled
as part of the build on the target platform. I think this isn't a
good thing.

No, it means tramp-drop-volume-letter has a bug that needs to be
fixed, IMO.

Lisp files are not supposed to be recompiled on the target platform.
They are architecture-independent, and are installed in a directory
which can be shared among different architectures.
Sorry, but I think this is a grave bug.

The problem seems to be, that defalias is evaled during
byte-compilation. So I will revert the definition of
tramp-drop-volume-letter, that is is decided at runtime how it is
defined.

Yes. Unfortunately, all pretests for MS Windows were compiled on MS
Windows. So this hasn't been detected earlier.
What shall we do with Emacs 24.3 for MS Windows? I still believe, that
we must repackage it, and compile tramp.el on MS Windows.
Alternatively there could be an Emacs 24.3a with a changed tramp.el. But
this sounds too heavy to me.
Best regards, Michael.

Thanks. It's probably best to do this on the emacs-24 branch.

I agree (but I think it's tramp-sh.el that needs to be recompiled).
And people who build their own Emacs from sources should recompile
tramp-sh.el on Windows.

Agreed, I see no need for that.

Well. I have reverted the change of `tramp-drop-volume-letter' to the
definition as it has been before the change in #105625. Compiled
tramp.el and tramp-sh.el on GNU/Linux. Copied the resulting tramp.elc
and tramp-sh.elc into the Emacs 24.3 tree on MS Windows. The problem
persists.
I have the impression, that there is a byte-compiler optimization, which
throws away the call of `tramp-drop-volume-letter' in
`tramp-sh-handle-expand-file-name'. As I have said earlier,
(tramp-drop-volume-letter "c:/something") still works correctly.
How could I avoid this eager optimization?

Revision 105625 cannot be the culprit, because it was done well before
Emacs 24.2 (which doesn't have the problem) was released. It's got to
be something in the byte compiler.

For this problem it might be the right thing to do. But we shall
continue to investigate (Stefan?), because this problem could happen
elsewhere.
I've committed a respective patch to the emacs-24 branch. Shall we put
a note somewhere, that tramp-sh.el of Emacs 24.3 needs to be recompiled
on MS Windows?
Best regards, Michael.

I couldn't think about any proper place. This discussion is already
one way to make this issue and its solution known. But if someone
comes with suggestions to advertise this in other places, I'm for it.

I think it's eval'ed when compiling tramp-sh because there's a
(require 'tramp) form there, see (info "(elisp)Compilation Functions"),
so this has nothing to do with defalias:
[1 /tmp/lisp]$ cat foo.el
(message "Hi! I'm being evalled.")
(provide 'foo)
[2 /tmp/lisp]$ cat bar.el
(require 'foo)
[3 /tmp/lisp]$ emacs --batch -Q -L . -f batch-byte-compile foo.el
Wrote /tmp/lisp/foo.elc
[4 /tmp/lisp]$ emacs --batch -Q -L . -f batch-byte-compile bar.el
Hi! I'm being evalled.
Wrote /tmp/lisp/bar.elc
[5 /tmp/lisp]$

Agreed, but it might be in the byte-compiler rather than in Tramp.
At least, nowhere does Tramp seem to request that
tramp-drop-volume-letter be inlined, so the call should stay in.
Stefan "probably guilty"

I think I know what's going on:
The byte-compiler now optimizes aliases to a function in the same way as
that function (so if you alias `my-add' to `+', (my-add 5 6) can be
optimized to 11 as well).
So your alias to `identity' is optimized just like `identity', IOW it's
compiled away.
This was made on purpose, because it's annoyingly difficult to define
such "optimized alias" without it.
One way around it is to use (lambda (x) x) instead of `identity'.

I have thrown away the alias in tramp.el, using an ordinary defun as
suggested by Eli.
However, it shall be documented somewhere that there's such an
optimization trap now with defalias.

Can the optimizer be taught not to optimize like that if the condition
includes one of a list of known symbols? Then we could maintain a
list of platform-dependent symbols whose optimization could lead to
platform-dependent .elc files.

The byte-compiler does not look at the `defalias' expression, only at
the resulting value of (symbol-function 'tramp-drop-volume-letter), so
it would require significant changes to be able to keep track of the
corresponding info. Also, `defalias' is a function, so by the time it
is called it has no idea what expression was computed to get the
function definition.

Too bad. Maybe there are other ways to avoid inadvertently producing
platform-dependent byte code, or at least warn about its possibility.
Otherwise, we are at the mercy of our less than perfect attention, and
these incidents will surely happen again.

As a work-around, byte-compile tramp-sh.el on Windows, and the problem
will disappear.

The reported bug here was fixed, so I'm closing the bug report. (The
discussion then continued onto the problem of the .elc files not being
portable between systems (because of byte code optimisations? I just
skimmed the thread), which is, I guess, a thing. If somebody wants to
follow up on that, then perhaps a new bug report should be opened.)
