Ok. But this still does not fit with your redisplay change - i.e. if you
put anything else on that hook you may get screwed.
for example?
Nevertheless I will

It does when you add a redisplay hook that is based on changes to the
buffer-alist.
this makes no sense. what if the tabs displayed the last few files opened? do
we have to modify find-file to trigger redisplay?

There was no bug, as I say it was an ideological change.
there was and is a bug. changing the contents of the gutter isn't causing the
gutter to get redisplayed. redisplay should NOT be triggered by record-buffer.
it should be triggered only when the code in gutter-items changes the gutter.
>btw you commented out my defer-window-pos code; why?
Because I wasn't sure whether this was obscuring other display-related
problems. IMHO it shouldn't be necessary and is a window-system specific
change. As you can see it left the code in and will re-enable it by default
when things have settled down.

Given time, crashes take priority. But please give me some indication that
you are not simply going to rewrite things yet again.

Give me a chance, I had 424 mail messages after 3 days holiday and only a

The hook you added has nothing to do with the tab display - simply with the
frame buffer list. The hook needs to be called when this list changes so
that the tabs instantiators get updated (not their display). Given *where*
it is called you need to make sure that it *is* called. The hook is bogus
for the example you give above, you would put it on find-file-hooks and
redisplay would take care of the rest.

Yes, but Ben the whole point is finding an appropriate place to change the
tab instantiators when a buffer changes, there were no hooks that I was
aware of that would do this and putting it on record-buffer seemed about
the only effective way of doing this. Changing the content of the gutter
should (and does) cause the gutter to be redisplayed, if this is not the
case then it is a bug that will not be helped by the change I made. I fixed
your original bug report about this so I assume you are referring to
something different - an example would help.

I don't think it always does. I reported this a week ago (screenshot
and everything); have you fixed it? I think I have seen this happen
and stay "stuck" when the tabs change. I've seen a couple of variants
that I haven't been able to duplicate, too. It's time for me to go to
bed, otherwise I'd try to confirm with recent CVS.

Oh, that.
At line 2744 of src/glyphs-x.c:
XtSetArg (al [0], XtNtopWidget, child);
child can be NULL. I don't know how it gets that way. :-) I do know
that the string being passed to XtNameToWidget is the appropriate
buffer name, so presumably something is wrong with the widget being
passed to XtNameToWidget. When that NULL later gets passed to an Xt
function, blam!
As far as I can remember, the crash always occurs on an attempt to
select the buffer that was originally in the leftmost position on the
tabs (manager) widget. It seems likely that that label (ie,
individual child tab) widget never had a next. Maybe you should use a
circular list there?
My initial reaction to the "callback" in buffer.c was like Ben's, but
now I see what you are up to. I'm not sure it's the right way to
signal the widget that its list has changed, but I do see your point
that something has to do it.
On the other hand, I think that using Lisp ojects in the widget's
internal structure is a dubious design decision. For example, in the
loop at line 2744 of src/glyphs-x.c, the fact that you are chasing two
lists which are assumed to be isomorphic is concealed by the use of
the LIST_LOOP macro. I'm not even sure that they should be isomorphic.
(Eg, we could surely avoid this crash by using a circular list of
children, which would not be isomorphic to the monotonic list of
buffers. This might result in a different kind of bug, of course.)
Another thing is that for a tabs widget, I don't see why any of its
children ever need to be destroyed before the tabs manager itself is
destroyed. Memory leak? Yes, but it's bounded. The tab widget takes
up screen real estate, so (absent a mad list-creating function whose
value is assigned as the label list for the tabs widget) the user
won't let it grow too much. (Of course we should worry about extreme
behavior; I'm talking about the ordinary case.) So I see the
interface to the widget as
struct tabs {
LispObject current_list_of_strings; /* read only */
LispObject requested_list_of_strings; /* effectively write only */
LispObject current_top_widget; /* read only */
LispObject requested_top_widget; /* effectively write only */
LispObject current_display_parameter_list; /* faces etc, read only */
LispObject requested_display_parameter_list; /* effectively write only */
}
The implementation would be a private TabsWidget object. (In practice
the requested_* objects would be parts of a separate instantiator, as
Ben is requesting, rather than a permanent part of the structure.)
The point of this design is that you _never_ have to read data from
the lw- or Xt-level TabsWidget. Your comments sprinkled throughout
the code indicate that that is problematic. And it's easy enough to
generate SIGSEGVs just reading Xt objects :-(.
The interface would be to setf the RLOS or get the CLOS. When you
setf the RLOS, the widget's redisplay callback notices this, and walks
both lists. When corresponding objects differ, set
tabLabelWidget.string(i) = CLOS(i) = RLOS(i) and a dirty flag on
tabLabelWidget(i). In case len(RLOS) > len(CLOS), new TabLabelWidgets
are allocated and initialized. Optionally, if len(RLOS) < len(CLOS),
you could free some TabLabelWidgets, but unless there are a lot to be
freed it's probably better to just unmanage them.
Note that this could actually be efficiently separated into two loops,
since you only need to compare addresses of tabLabelWidget.string(i)
and CLOS(i).
Similar considerations would apply to the top tab and the display
parameters, except that those would be fixed structures. This should
make it possible to set all the labels, display parameters, and the
topWidget with one call to XtSetValues().
I don't think this is so different from what you're doing now, except
that discussing it this way shows that all this stuff could be handled
in about three places in the code (tabs instantiation, tabs redisplay,
and the implementation of TabsSetValues() in lwlib/xlwtabs.[ch]). But
at the moment things seem to be spread out all over. (At least,
looking at TabsSetValues(), x_tab_control_instantiate(), and
x_tab_control_redisplay() gives the impression that something must be
handled elsewhere.) And the role of things like the hook in buffer.c
get confused; it looks like it's tab-specific when actually it's
intended as a general facility that wasn't needed until buffer tabs
came along.

The patch below fixes the crash, but buggifies the tabs (that is, the
current buffer and the tabs get unsynched each time the assert fails):

There are four buffers in the initial tabs: ben-mule.diff~,
ben-mule.diff.orig, ben-mule.diff, and *Group* in that order.
Clicking the tabs more or less randomly produces the following on
stderr:
bash-2.04$ uh-oh, busted tabs! (buffer ben-mule.diff~)
uh-oh, busted tabs! (buffer ben-mule.diff.orig)
uh-oh, busted tabs! (buffer ben-mule.diff.orig)

uh-oh, busted tabs! (buffer ben-mule.diff~)
uh-oh, busted tabs! (buffer ben-mule.diff~)
uh-oh, busted tabs! (buffer ben-mule.diff.orig)
There doesn't seem to be any way to get the error to occur for one of
the other buffers, and they never end up in the leftmost positions;
those are monopolized by the two buffers producing the error
messages.
I don't ever get a crash, so it's always a null Widget pointer when
things are bogus.
My hypothesis that the widget passed to XtNameToWidget might be bogus
is presumably wrong; it's constant in the code.

Been there, done that. It still doesn't explain why the tab is not
available for selection. I am currently suspicious of my update code. If
you load a whole bunch of files and then run editres on XEmacs you will see
an equal number of widget trees with an increasing number of tabs. This is
wrong there should be at most two - one for the minibuffer and one for the
current buffer. So somewhere along the line more are getting instantiated
instead of the current one being updated. This may mean that when you
select a different buffer the relevant tab widget is now different (with
less tabs) and so selecting a tab causes a crash.
But I still haven't worked out why the image instance is getting
instantiated rather than updated.

This would be consistent with the leftmost tab being most commonly
involved in crashes, and also with crashes occurring when the tabs sort
of randomly change order (which they do).

Because that's what the code does?
Tracing through the code, I see that update_glyph_instance_data()
calls glyph_image_instance(), which calls specifier_instance(), which
calls the glyph's instantiate method. No conditionals that I can see.
The other kind of glyph whose instantiation is really expensive is
images, and they short-circuit the instantiation process in
glyph_image_instance_maybe().
So either x_tab_control_instantiate() needs to know about the glyphs
it has already created, which seems bizaare, or you should use
glyph_image_instance_maybe(). That function may need to be updated to
know about widgets.
Or maybe you need to avoid update_glyph_instance_data() itself, as
changing it might be wrong for other callers.

OOoooh, shiver. You trust THAT code to match a glyph whose
instantiator ... uh, uh, what is an instantiator for a tab control? I
hope it doesn't contain anything about the number of tabs, their
labels, or which one is the top. Or else it changes every time you
switch buffers!
If you want to accurately cache the tab control, then its instantiator
should be the object (frame, I guess) it's associated with.
Everything else needs to be set from another part of the API. Is that
so?
FWIW, here is the back trace. All from one run, in an XEmacs which
traps the "bad" accesses. All breakpoints except the first were
associated with bad accesses, but many bad accesses occurred without
causing instantiation. The bad access always happened before the
instantiation I think.

OOoooh, shiver. You trust THAT code to match a glyph whose

hope it doesn't contain anything about the number of tabs, their
labels, or which one is the top. Or else it changes every time you
switch buffers!
Urrg. That is a problem but not much of one - I've just changed the hash
test back to EQ which is correct for the current setup. However the real
problem is that the instantiation domain *changes* because the window
changes. Thus right now the only thing to do is to change the instantiator
in the window which means I can't do the optimization I've been trying. I
really need to instantiate at the frame level (which has its own problems)
or "fake" it.
I need to think.

New subject: evil hack in buffer.c, and need for internal docs onwidgetcode
At 02:13 PM 8/10/00 +0900, Stephen J. Turnbull wrote:
On the other hand, I think that using Lisp ojects in the widget's
internal structure is a dubious design decision. For example, in the
loop at line 2744 of src/glyphs-x.c, the fact that you are chasing two
lists which are assumed to be isomorphic is concealed by the use of
the LIST_LOOP macro. I'm not even sure that they should be isomorphic.
(Eg, we could surely avoid this crash by using a circular list of
children, which would not be isomorphic to the monotonic list of
buffers. This might result in a different kind of bug, of course.)
Remember that this is only neccessary under X because of lwlib. Under
mswindows the glyph structure encapsulates all of this information.
Another thing is that for a tabs widget, I don't see why any of
its
children ever need to be destroyed before the tabs manager itself is
destroyed. Memory leak? Yes, but it's bounded. The tab widget takes
up screen real estate, so (absent a mad list-creating function whose
value is assigned as the label list for the tabs widget) the user
won't let it grow too much. (Of course we should worry about extreme
behavior; I'm talking about the ordinary case.) So I see the
interface to the widget as
struct tabs {
LispObject current_list_of_strings; /* read only */
LispObject requested_list_of_strings; /* effectively write only */
LispObject current_top_widget; /* read only */
LispObject requested_top_widget; /* effectively write only */
LispObject current_display_parameter_list; /* faces etc, read only */
LispObject requested_display_parameter_list; /* effectively write only */
}
The implementation would be a private TabsWidget object. (In practice
the requested_* objects would be parts of a separate instantiator, as
Ben is requesting, rather than a permanent part of the structure.)
The point of this design is that you _never_ have to read data from
the lw- or Xt-level TabsWidget. Your comments sprinkled throughout
the code indicate that that is problematic. And it's easy enough to
generate SIGSEGVs just reading Xt objects :-(.
The interface would be to setf the RLOS or get the CLOS. When you
setf the RLOS, the widget's redisplay callback notices this, and walks
both lists. When corresponding objects differ, set
tabLabelWidget.string(i) = CLOS(i) = RLOS(i) and a dirty flag on
tabLabelWidget(i). In case len(RLOS) > len(CLOS), new TabLabelWidgets
are allocated and initialized. Optionally, if len(RLOS) < len(CLOS),
you could free some TabLabelWidgets, but unless there are a lot to be
freed it's probably better to just unmanage them.
Note that this could actually be efficiently separated into two loops,
since you only need to compare addresses of tabLabelWidget.string(i)
and CLOS(i).
Similar considerations would apply to the top tab and the display
parameters, except that those would be fixed structures. This should
make it possible to set all the labels, display parameters, and the
topWidget with one call to XtSetValues().
I don't think this is so different from what you're doing now, except
that discussing it this way shows that all this stuff could be handled
in about three places in the code (tabs instantiation, tabs redisplay,
and the implementation of TabsSetValues() in lwlib/xlwtabs.[ch]). But
at the moment things seem to be spread out all over. (At least,
looking at TabsSetValues(), x_tab_control_instantiate(), and
x_tab_control_redisplay() gives the impression that something must be
handled elsewhere.) And the role of things like the hook in buffer.c
get confused; it looks like it's tab-specific when actually it's
intended as a general facility that wasn't needed until buffer tabs
came along.
The correct solution given our current use of lwlib would be to factor the
code into lwlib so that lw_modify_all_widgets did the Right Thing. And this
is possible. However, doing this in lwlib is always a complete PIA *and*
difficult to get right *and* takes a long time. When actually what we are
trying to do is quite simple.
The abstraction of lwlib is laudable but IMHO makes things more complicated.
The mswindows code was very easy to get right because of the absence of lwlib.
BTW the current lisp structure using gui_items is mainly because we already
have functions to convert these into what lwlib is expecting.
