Subject: 25.0.50; Yanking text on a MS-Windows console
Date: Sat, 4 Oct 2014 23:04:07 +0200

(OS: MS-Windows 8)

Recipe:
  Copy some text in the system clipboard.
  emacs -nw -Q
  C-x h C-w C-y

The yanked text is not the one just killed, but the contents of the
clipboard.  And (FWIW) if I type M-y (just after the C-y), then I get
the killed text.

Obviously, that's a mess up of mine.  But since I can't test under w32,
I'm going to need your help.

So, to get started, can you `trace-function' on gui-select-text,
gui-selection-value and then reproduce the above (and show me the
resulting trace)?

One more thing: if you don't do the C-w, what is the expected behavior?
IOW did the w32 console use the w32 clipboard?

gui-selection-value seems to be undefined at that point, therefore I
cannot "trace-function" on it.

This is the resulting trace for gui-select-text:

<trace>
1 -> (gui-select-text #(";; This buffer is for notes you don't want to
save, and for Lisp evaluation.
;; If you want to create a file, visit that file with C-x C-f,
;; then enter the text in that file's own buffer.

" 0 3 (fontified t face font-lock-comment-delimiter-face) 3 77
(fontified t face font-lock-comment-face) 77 80 (fontified t face
font-lock-comment-delimiter-face) 80 140 (fontified t face
font-lock-comment-face) 140 143 (fontified t face
font-lock-comment-delimiter-face) 143 190 (fontified t face
font-lock-comment-face) 190 191 (fontified t)))
1 <- gui-select-text: #(";; This buffer is for notes you don't want to
save, and for Lisp evaluation.
;; If you want to create a file, visit that file with C-x C-f,
;; then enter the text in that file's own buffer.

" 0 3 (fontified t face font-lock-comment-delimiter-face) 3 77

font-lock-comment-delimiter-face) 143 190 (fontified t face
font-lock-comment-face) 190 191 (fontified t))
</trace>

The expected behavior for that, I think, is the one I observe right
now: C-y brings to the buffer the current contents of the system
clipboard.

Looks like you have an "old" version, then.  Try updating from trunk.

I think if you upgrade from trunk, your original problem might
disappear, but the above desired behavior will also disappear.

If so, please try to run the code below and tell me if it restores the
expected behavior:

(gui-method-define gui-selection-value t #'w32-get-selection-value)
(gui-method-define gui-select-text t
                   (lambda (text)
                     (if gui-select-enable-clipboard
                         (w32-set-clipboard-data text))))

My version was from a recent trunk build (2014-10-02), made from an
empty build directory (autogen.sh+configure+make).  But it seems that
it is somehow corrupt.  I guess I should always use the "bootstrap"
target to be sure that the build is correct...

Yes, It seems so.  I've just built a recent trunk version, and this is
what I see:

1. Without your code below:
  a. The kill ring seems to work OK for "internal" text, i.e, text
     coming form Emacs itself.
  b. But I can't yank text from the system clipboard.

2. With your code below: Everything seems to work fine.

Great, thanks.  The problem should be fixed in trunk now.
