The legal stuff that we were waiting on has been sorted out, so, barring
unforseen circumstances, we will begin the pretest next week.

There is one more task that needs to be done---moving the pmail files to
replace rmail.  Could someone please take care of that?  The pmail files
are now in a correct state, so this just involves replacing `pmail' with
`rmail' everywhere in those files, and changing the file names.

Still the Cocoa/GNUstep port doesn't handle C-g properly.  I think
this issue should be addressed before the pretest because it is
expected to require nontrivial changes in its event handling part.

Sure.  I don't think "nontrivial changes" would be required.  As I  
outlined earlier  (http://thread.gmane.org/gmane.emacs.devel/105688/ 
focus=105694):


1) Complete removal of all Feval() calls in bad places as discussed  
earlier on this list.  A quick check reveals four places, relating  
to: emacs termination, deadkey input handling, toolbar toggle, and  
preferences-help.

- Mostly straightforward (but taking some time) by using custom  
'nonascii-keystroke' events, except for the case of input-method  
handling when in isearch mode, where passing such an event breaks out  
of the isearch entry; I could use some help on this.


2) Go through the code comparing nsterm and macterm input handling to  
make sure all ctrl-g related processing is similar

- I did this at one point, but it should be re-checked if problems  
remain after (1) and (3).


3) Make sure some kind of interrupt mechanism is in place to pick up  
ctrl-g events when emacs core is busy processing and does not itself  
make passes through the NS code event loop (colored spinning disk  
shown in gui).

- I did some experimentation for (3) using a signal handler a while  
ago but something didn't seem to work, and some investigation is  
needed.  I don't think major changes to the port event-handling would  
be needed  since the issue is interrupts during emacs core  
processing, not inside the Cocoa processing.  It should just come  
down to getting whichever interrupt mechanism worked in the Carbon  
port on OS X during emacs-core processing to be active in the Cocoa  
port.  I would welcome help on this.


Recently I've been spending the time I've had for the port on fixing  
the bugs reported by users (http://emacsbugs.donarmstrong.com/cgi-bin/ 
pkgreport.cgi?package=ns), so I haven't made any progress on these yet.

That's OK, I think.  The code is definitely not frozen once the pretest
starts.  But in any case, I urge you (or whoever is able to work on
this) to do it ASAP.

There are several bugs that I was unable to close by writing to
NNN-done@, and not even by sending "close NNN" commands to the control
address. I've been able to close them by sending a control message
referring to other bugs, for example

  reassign MMM spam
  close NNN
  quit

Done.  I removed old rmail* files, except rmail-spam-filter.el.  
I renamed (i.e. deleted+added) pmail* files to rmail*.

I tested quickly, it looks okay.  Please test further.

I didn't move lisp/mail/Changelog.pmail yet.  Shall I merge this
changelog with lisp/ChangeLog?

There's also the ChangeLog to consider. The minimum I suppose is to
dump ChangeLog.pmail into the head of ChangeLog, with the dates
adjusted to today (or whenever), and s/pmail/rmail. The ideal would be
to then compress that so it only shows the actual differences between
yesterday's rmail and today's (a real PITA).

There's the arch tags to consider.

Rather than clobbering the files, the ideal way to do this is
presumably to look at the diffs between rmail and pmail, and only
apply the ones that make sense. (Not volunteering!)

Most likely those events should not be handled by the global-map, but
instead either directly by the C code (e.g. in kbd_buffer_get_event), or
via special-event-map, or via input-decode-map.

Also, there are numerous non rmail*.el files that refer to rmail
functions and variables, and these all need to be checked because in
some cases the interface has changed or been removed. Many are in
packages like gnus that will want to work with both old and new rmail.

What was the point of cvs removing the old rmail files first?
AFAICS, it did nothing but send out two sets of massive, meaningless
mails to the diffs list.

My concern is that the lack of proper C-g handling for such a long
term may imply a problem in the fundamental design of the port.  Of
course, no one can be sure unless someone refutes it by actually
implementing it.  I think maintainers should set some time limit to
wait such an implementation, and IMO the beginning of the pretest is
the most appropriate timing.  Even if "nontrivial changes" is not
necessary as Adrian says, there should be enough time to test the new
code before the release.

Right now, there seem to be rmail*.el and pmail*.el files which are the
same except for prefix-renaming (pmail  -> rmail).

Is this a mistake?  It seems like a useless state of affairs...  why not
just remove the pmail*.el files?

[and yeah, the arch tags are screwed up because of it -- but it seems like
the correct solution to that problem is just to remove pmail*.el]

I'd have thought you'd want to restore the previous tags. Today's
rmail.el is just yesterday's with some changes merged in from a branch
(via a strange route). But I don't know arch.

I've just checked in the latter approach (and yes, it was a PITA).

Awesome. I'll stop with the former approach then. :)

The rmail*.el and pmail*.el files are now _exactly_ the same, except for
trivial renamings:

   $ for p in lisp/mail/pmail*.el; do
         r=`echo $p | sed s/pmail/rmail/`
         b=`basename $p`
         t=/tmp/,pr-$b
         echo $p vs. $r:
         sed 's/pmail/rmail/g;s/PMAIL/RMAIL/g;s/Pmail/Rmail/g' $p > $t
         diff -u $t $r
     done
   lisp/mail/pmail.el vs. lisp/mail/rmail.el:
   lisp/mail/pmailedit.el vs. lisp/mail/rmailedit.el:
   lisp/mail/pmailkwd.el vs. lisp/mail/rmailkwd.el:
   lisp/mail/pmailmm.el vs. lisp/mail/rmailmm.el:
   lisp/mail/pmailmsc.el vs. lisp/mail/rmailmsc.el:
   lisp/mail/pmailout.el vs. lisp/mail/rmailout.el:
   lisp/mail/pmailsort.el vs. lisp/mail/rmailsort.el:
   lisp/mail/pmailsum.el vs. lisp/mail/rmailsum.el:
   $

Thus the pmail*.el files seem to serve no purpose, and having them
around is confusing.  Why are they being kept?

I checked org-rmail.el which works fine.

The mairix.el interface to Rmail is now partly broken (e.g. when doing
searches based on the current mail). I'll do some further testing and
send a patch in the next few days.

I don't understand; but it's history now anyway. I wouldn't do it that
way in future is all.

? It uses rmail-narrow-to-non-pruned-header, a function which doesn't
exist any more.

I'm also at present unsure if rmail-show-message behaves differently
now, and if rmail-show-message-maybe has taken over the old behaviour.

I've added a list of files to FOR-RELEASE (based on not much more than
the edited results of grep). Some may be trivial to remove.

I tried using special-event-map, following the example of delete- 
frame, but I still get a "Wrong type argument: commandp, ns-echo- 
working-text"  message.  I'm trying to get ns-echo-working-text  
called non-interactively so it can make some text changes in the echo  
area.  Is there any way to do this?

(See ns-win.el for defn of ns-echo-working-text.)

I won't dispute the second sentence, but the lack for a long term is simply
because I've never found it a problem in my own usage patterns, and users
haven't been particularly vocal in complaining about it either.  There have
been other priorities.  But it's top of my list now.

BTW, the one other major gap in the port is dumping under GNUstep.  I posted a
suggestion for this a while ago, which came down to adding some
zone-allocation functionality to unexelf.c/NS_IMPL_GNUSTEP paralleling
unexmacosx.c.  If anyone is running under GNUstep and would like to take a
crack I can provide further advice offline.

Hello all

I have one issue with current cocoa/gnustep port - in some situations it
improperly show symbols on the screen when i used letter from different
charsets - some letter rendered higher than other.  I tried to explicitly
specify concrete fonts, instead of font classes, but it has same effects.

You can see this in the second header on the screenshot at
http://xtalk.msk.su/~ott/files/Emacs23.png called "Настройка Semantic для
работы с проектами на C & C++".  This screenshot was made from GNU Emacs
updated & built today

But in current Carbon Emacs (GNU Emacs 22.3.2 (i386-apple-darwin8.11.1,
Carbon Version 1.6.0)) all works fine, as you can see on the
http://xtalk.msk.su/~ott/files/CarbonEmacs.png

Adding (interactive) will fix that, of course.

Never mind, after more experimentation it seems that having an  
interactive function is needed and OK now -- the problem w/putting  
text in the echo area must be a difference between going through the  
special-event-map and NONASCII_KEYSTROKE.  I will try to clean up the  
patch below and repost before submitting.

I'm really surprised to hear that it hasn't have the top priority.
I've been thinking that proper C-g handling is a minimum requirement
to be a part of the official Emacs rather than an unofficial
distribution.  Without it, the port wouldn't be a "real Emacs".
Anyway, good to hear that now it has the top priority.

Here, the issue is that the SIGIO handler is never called, despite  
being registered.  It might be overridden by Cocoa in some way,  
though I haven't been able to fully confirm this.

In any case, I tried to use input polling (Fset_input_interrupt_mode  
(Qnil)), but poll_for_input() does not get called during, for  
example, (while t t).  It seems that the QUIT macro does nothing to  
update timers so the polling timer never fires.  Making the QUIT  
macro call handle_async_input() every time slows down emacs (esp  
during startup).

Does anyone have any suggestions?


thanks,
Adrian

Have you checked whether the SIGIO handler is registered in the first
place?  Also, have you confirmed that the handling function is indeed
never called (as opposed to a bug that makes it do nothing)?

What is "improper" in how C-g is handled on Cocoa?

Yes, signal() IS called with SIGIO, input_available_signal(), and the  
latter is never called (according to an fprintf which works fine  
running under X).  I also tried calling signal() at various later  
times, in case the handler gets replaced.

Not at all, actually.  I found that even Feval calls from
read_socket_hook are not completely removed (at least, menu bar
activation and OK button click in the preference panel.)

It makes almost all uses of QUIT macro throughout the source code

What happens if you do a "kill -IO <...>" from the shell?
Is your fprintf properly executed?  I.e. is it that the proicess doesn't
receive any IO signal or is it that those signals don't invoke your
signal handler?  Also, could it be that the signals get delivered to
another thread?

On w32, we set Vquit_flag directly when Ctrl-G (quit_char) is pressed. 
This is done in the asyncronous key handling where the event gets put on 
the Lisp input queue, so it does not have to wait for the input queue to 
be polled.

Could you please supply a few more technical details, assuming that I
know something about how C-g is supposed to work in Emacs?  What
doesn't work on Cocoa that works on GNU/Linux and other platforms?

Hi,

Do you have any technical suggestions as to how to handle it given
that SIGIO seems not to be available?  As I posted, polling (keyboard.c
start_polling(), stop_polling(), etc.) seems not to happen through
the QUIT macro (perhaps it did at one time but the functionality was
lost after all terms went to SIGIO-based?).

One thing that would work would be to update the polling timer inside
the QUIT macro (under HAVE_NS of course), so that poll_for_input()
would eventually get called.  But I don't know if there are reasons
this would be dangerous or something, or if there would be another way.

thanks,
Adrian

What is the entry point for detecting the Ctrl-G (or any other user  
keyboard input), when a tight loop is running, such as (while t t)?   
Is the SIGIO signal handler used, or is W32 itself asynchronously  
calling something in w32fns.c or w32term.c on a second thread?

thanks,
Adrian

I just noticed the menu one, actually.  Do you have an automated

If a Lisp expression doesn't contain any direct or indirect call to
some read operation, its evaluation cannot be quit in the
Cocoa/GNUstep port.  Simple examples are (while t) and (shell-command
"sleep 100").

Not an automated way.  I just did some random experiment (with

I think this is done in the SIGIO signal handler (at least, according to
the comment for w32_read_socket in w32fns.c).  Jason, could you confirm
this?

W32 does not have a SIGIO signal handler, so that comment is probably a 
copy and paste error. On Windows, a second thread is listening for 
window system messages. w32_read_socket is the Lisp thread's message 
handler, C-g detection is done in post_character_message (w32fns.c) 
which is the point where the input message is posted from the window 
system message handling thread to the lisp thread.

This could probably be done under NS as well.  There might be issues  
with one or the other thread needing to be the "primary" one, and  
some degree of rearchitecting would be needed, using the W32 port as  
a guide.  So, it might be simpler if there's any way to get the  
conventional keyboard.c timer-driven input polling done through the  
QUIT macro under NS.

There is no such thing as a timer-driven polling in the QUIT macro.
The polling done via the QUIT macro is "polling for some C var to
change", not "polling for some external thingy".

Right.  The polling I meant was running poll_for_input() in  
keyboard.c in response to the atimer 'poll_timer' firing, if running  
in polling mode (Fset_input_interrupt_mode(Qnil)).  I wasn't sure if  
atimers just weren't supposed to be called while tight loops are  
running, or if some code just wasn't working as expected under NS.   
My initial thought was to add something like

   do_pending_atimers();

to QUIT under HAVE_NS.

As it turns out, this isn't needed.  SIGALRM is triggering  
alarm_signal_handler() in atimer.c correctly, but run_timers() never  
gets called under SYNC_INPUT.  I don't fully understand why or where  
the problem is here.  But undefining SYNC_INPUT gets poll_for_input()  
called (and hence Ctrl-g detected) even in tight loops, with no ill  
effects so far.  Patch below.

It would be of interest to find out why it fails under the SYNC_INPUT  
case...

I also investigated the SIGIO thing a bit more.  I can trigger the  
handler using kill -IO from the command line.  But no SIGIO seems to  
be being sent to the process when keyboard input is given.

I wrote SYNC_INPUT specifically for X11 input handling.  From what you
say above, there is apparently a bug in the way it handles SIGALRM.

Apparently the QUIT macro should check pending_atimers somehow.
Can you try to tweak QUIT so it does

   else if (pending_atimers)
      run_timers;

to see if it fixes your problem?  If so, we should probably create a new
var `pending_signals', which should always reflect
"pending_timers || interrupt_input_pending", then QUIT can check this
var, and if set, it can call a new function `process_pending_signals'
which will then look at pending_timers and interrupt_input_pending to
figure out which function(s) to call.

pending_timers and process_pending_timers are desired/needed to reduce
the code-size (the QUIT macro is expanded at many places), as well as to
reduce the polling overhead.

Yes, adding

     else if (pending_atimers)				\
       do_pending_atimers();				\

at the end of QUIT allows poll_timer() to fire under SYNC_INPUT and  
Ctrl-g to be detected, with no apparent other ill effects (in very  
limited testing).

I'm not sure if the extra 0-comparison would significantly add to  
overhead but I guess code size could take a hit.  Though maybe the  
part of QUIT above (when there is a quit_flag) could also be reduced  
to a function call to slim things down?

So basically any place in the code that sets pending_atimers or
interrupt_input_pending would have to set pending_signals as
well---something like in the attached patch?

It's not clear to me whether we want to process pending atimers in the
QUIT macro outside of NS.  Do we?

Those seem to be problems that are common to the systems that use
polling instead of SIGIO.  I think you can rather concentrate on Feval
removal for now, leaving those problems to others.  In particular, if
you are planning to call read_socket_hook at the QUIT timings, you
should never start menu bar tracking there.

Yes, that would be good as well.

I think we do: the non-SYNC_INPUT code processes them directly from the
signal handler, AFAICT.

----------------
I am not sure code size is really an issue. Emacs executable is already huge.
On the other hand, merging flags set by different signal handlers is a problem.
It is quite possible for a signal handler to fire when another signal handler is 
running, unless other signals have been blocked. This can interfere with 
setting of those flags.

It is perhaps safer to leave the flags separate. Other option is to block all 
signals that can interfere, possibly using sigaction() instead of signal(), 
but I am not sure of availability on all supported platforms.

How do you recognize the current status and perspective of the C-g
issue in the Cocoa/GNUstep port?  The changes made so far weren't
"nontrivial", indeed.  But I meant by "nontrivial" the still remaining
"Feval call in menu bar activation".  Actually, menu bar tracking
itself is problematic inside read_socket_hook if the Cocoa/GNUstep
port is trying to follow what the Carbon port does with respect to
C-g.)

Work on this may still proceed during the pretest; we are not yet in a
hard code freeze.  It is not serious enough to delay the start of the
pretest.

Of course, it's up to you maintainers whether to start pretest at this
stage.  But I dare to say it's a serious issue from my experience.

Bug #970 is still not fixed, as of today's CVS.  Is someone working on
it?  I don't think we can release Emacs 23 with this problem.

Also, I think we need to start the docs reviewing process ASAP.  Emacs
23 changes a lot, so finding all the obsolete and/or incorrect places
in the docs will take some time.  For past major releases, we used to
have at least 2 different people proofread each portion of the 2 main
manuals, so I think we need to have in admin/ some record of who
proofreads what.

I wonder if I'm the only one who is not able to compile emacs anymore
(bug #2097) when configuring with --with-libotf.

I can compile Emacs with libotf successfully.

What is shown by this command?

% pkg-config --modversion libotf

And, does ALL_CFLAGS in src/Makefile contain the output of this?

% pkg-config --cflags libotf

That returns "-I/usr/include/freetype2" which is included in ALL_CFLAGS.

???  How did you install it?  It's completely different from
the header file that libotf requires (attached at the tail).

    Work on this may still proceed during the pretest; we are not yet in a
    hard code freeze.  It is not serious enough to delay the start of the
    pretest.

If fixing this will require major changes, that may be a reason to
delay the pretest -- if someone is willing to working on these major
changes right away.

In the platforms other than the Cocoa/GNUstep port, menu bar is
uniformly activated by the x_activate_menubar call in
kbd_buffer_get_event, which is called from read_char.  However, the
Cocoa/GNUstep port activates the menu bar and starts mouse tracking in
the context of read_socket_hook, which is supposed to be called from
fairly random states of the Lisp interpreter.  (That port currently
calls read_socket_hook only from limited locations, and that makes
this problem obscured and the C-g handling improper.)

I think this difference becomes a major obstacle if that port is
planning to solve the C-g issue during the pretest period by following
the strategies that are used in some existing platforms.

I installed it via paludis (Gentoo GNU/Linux).  I recompiled it (no
version change, still 0.9.8) and now /usr/include/otf.h is the same as
yours.

But looking at the old headers they state they're from some "Open Trace
Format" library.  I don't know how they got there.  Seems some broken
app I have to use at work had overwritten the original open type
header...

Thanks a lot for your assistance, emacs compiles again.

Bye,

If you want to start the pretest soon, I suggest putting off the
inclusion of the Cocoa/GNUstep port until Emacs 23.2 (or later).  In
particular, the GNUstep port doesn't have enough quality to start
pretest.

That would be counter-productive.  Consider the worst-case scenario of
keeping the Cocoa port: suppose that, just before the 23.1 release, the
port remains as irretrievably broken as you make it out to be.  In that
case, we can disable it by changing the build system, and mark it as
experimental/hackers-only.  So nothing is lost by keeping the port (and
I am optimistic that it will not come to that).

Since there's no alternative code for Mac nor for GNUstep, there's no
harm in providing it and nothing to gain from removing it.  If it's not
robust enough, we'll just label it "experimental" (which we'll probably
have to do for GNUstep, sadly).
Let's move forward.

OK.  Agreed except for the last parenthesis in the sense that I have

Not actually.  Both users can use some of X11 builds in the meanwhile
if they want to use the new version.

I thought it's shameful for Emacs to include a port that doesn't
handle C-g properly as a part of its official release.  Also, I was
not suggesting the removal of the port from the whole CVS branches.

What I would do can be found in my Carbon+AppKit port (*) for Emacs
22.  But that's not an "NextStep" port in the sense that it heavily
relies on Carbon on which the Cocoa event system is implemented.

I tried that with my Carbon+AppKit port first, but I abandoned it in
the very early development stage.  Because I'm relatively new to
Cocoa, there might be some way I don't know yet.  Anyway, I'm not 100%
sure.  If Adrian or someone else can find the way, that'll be fine.

Although almost all the GUI portion of Carbon will be deprecated,
that's not extended to the whole Carbon.  That's why I created the
Carbon+AppKit port from the Carbon port by only replacing its GUI
implementation (src/mactoolbox.c) with some Cocoa counterpart
(src/macappkit.m).

I believe it is working 100% now.  Please report any specific failure cases
you find through report-emacs-bug

The cost of the implementation has been that are some cases where menus are not
updated when clicked on; specifically, when ns_read_socket is called
asynchronously through handle_async_input or poll_for_input_1 (depending if
SYNC_INPUT is enabled), the menu update must be deferred.

I believe the effect of this on user experience will be rare to almost
nonexistent in practice, but let's find out empirically.  If it is a problem
there are a couple of approaches that could be tried, but I'd rather prioritize
other issues for now unless it proves to be a problem in actual use.

One more technical point: IMHO switching the Cocoa port to use the same
event loop integration method as W32 (a separate thread to run the GUI
toolkit event loop) would work as well under Cocoa as it does under W32.
But I'd prefer to avoid this sort of change unless the flaws in the
current integration, which has served a wide user base for many years,
prove unworkable.

What happens if read_socket_hook is called from the QUIT macro in the
context of process filters or idle timers?

That's actually a way I didn't adopt because it confuses the user: it
shows empty menu items if the user clicks the menu bar at the timing
of a read_socket_hook call from a QUIT macro in the context of process
filters or idle timers.

In the current implementation it does this only if menus have not  
been clicked on before (else the previous items, albeit out-of-date  
ones) are shown.  This is better than nothing, though it should be  
better.  However I'm not really sure how often this "clicks the menu  
bar at the timing of a read_socket_hook call from a QUIT macro"  
occurs in practice.  Anyway, what about the second-thread approach  
like W32, are there any gotchas you know about?

What happens if the user selects that "bogus" item?  Doesn't it
generate a bogus Emacs event that might not happen if the menu bar
activation is deferred?

The process filters and idle timers are a kind of "background tasks".
Users will expect that they can continue normal editing work (with
some delay, sometimes).  Also, some process filter takes time to
complete, and an idle timer can be designed so it can do a long task
if no input is pending.

I guess menu bar item calculation can be deferred but not for starting
menu bar tracking in the case of NS.  For example, I'm not sure if the
following scenario can work properly:

  1. Evaluate `(while t)'.
  2. The user clicks the menu bar.  The GUI thread starts to wait for
     menu items to be calculated in the Lisp thread.  The Lisp thread
     is not ready to do that because of the tight loop.
  3. The user types C-g to quit the loop.

Thank you, I confirm that most of the problems with compositions seem
to be solved, at least in the HELLO file display.

There are still a few strange phenomena with terminal display,
although they seem unrelated to compositions.

For example, after typing "C-h H", go to the line that begins with
"CJK variety", and type "C-f": you will see that the cursor jumps past
some of the characters inside parentheses.  Is this a bug?

No.  Those CJK characters have width 2, and if they are not
supported by the terminal coding system,
encode_terminal_code produces two '?'s.

Correction: bug #2564 shows that even "read_socket_hook only from
limited locations" is problematic.  In the reported case,
read_socket_hook is called from the select (ns_select, actually) call
in wait_reading_process_output, and a menu bar activation there leads
to Lisp evaluation containing Faccept_process_output.

I think the bug #2432 is also caused by the same reason.

menu item, which then triggers tramp to go and check on the server.   
This
causes a reentrant call to wait_reading_process_output, thence a  
reentrant
call to ns_select.  I've added a check in the latter to shortcircuit  
in the
reentrant case.  There is still a delay when requesting a menu, but  
this is
probably unavoidable if the visited modtime must be checked for each  
menu
item.

I've looked at your code in the Carbon AppKit port and it seems like  
your
approach to handling menu events there could be applied to the NS  
port.  The
only difference I see in your event handling is processing all event  
types in
one function instead of passing them through NSApp-sendEvent: to go be
distributed through ordinary Cocoa channels to widgets.  But since - 
sendEvent:
is an interception point, the menu events could be taken there.

I'm anxious whether the former reentrance (i.e.,

I vaguely remember that didn't work in some cases, maybe when Emacs is
used via "Screen Sharing.app" in Leopard.  Anyway you can try.

Because wait_reading_process_output also calls timer_check, its
reentrance would probably be OK.

Still, I think Feval calls from read_socket_hook and (emulated) select
are really bad.  Most developers assume that these functions (and some
higher-level ones such as detect_input_pending) don't call Feval, and
they may add some code without noticing that NS breaks such
assumptions.

Although I am still unsure how often in practice there is a problem
(the tramp menu crash was not reported until now, despite the
situation causing it on the NS end existing for years), I fully agree
that the menu event handling under NS should be fixed.  Given the menu
update model in emacs, the best solution is likely to defer the event
as other ports including Carbon+AppKit have done.  The only thing
stopping me is my lack of time right now, and a hesitation to
implement such a change during pretest.

That's why I suggested putting off the pretest or removing the
Cocoa/GNUstep port from the pretest.

This is not the only thing.  The recent "fail on osx between 2/4/2009
and 2/5/2009" thread reminded me of several "kludges" that should be
fixed before the release:

1. Different interface for existing functionality.

  a. ns-read-file-name vs. x-file-dialog
  b. ns-drag-{file,color,text} event + own handlers vs.
     drag-n-drop event + dnd.el
  c. ns-expand-space vs. line-spacing frame parameter
  d. nsfont_make_fontset_for_font vs.
     :lang/:script/:registry properties in font-spec

2. Interface is the same, but implementation is based on own interpretation.

  a. tooltip (not being an Emacs frame, it cannot make use of Emacs
     display features such as images.)
  b. selection concepts (local/foreign selection, ownership)
  c. rightmost scroll-bar placement (it doesn't consider the case
     where scroll bars in different width, e.g., C-x 2 M-:
     (set-window-scroll-bars nil 11 t) RET)
  d. internal-border-width
  e. fringe and cursor drawing

3. NS-only implementation for features that are not inherently specific to NS.

  a. preferences panel
  b. alpha-component in color specification
  c. color image for stipple (cf. tiling patch by Miles Bader)

4. Suspected fundamental design flaw.

  a. C-g handling
  b. menu bar activation timing

Please go ahead with it.  This is fixing a bug, not implementing any
new feature, it's quite within the scope of the pretest, although we
usually prefer not having to do such things.

Hi all,

I'm planning to make the 23.0.94 pretest next Wednesday, the 20th.

The release seems to be coming along nicely; the font code seems to have
converged at last (with the exception of #2667), and most of the
documentation work is now done.  I'm thinking of cutting the branch
after the next pretest, so that some of the pent-up patches can start
being applied.  I have not, however, discussed this in detail with
Stefan yet.  If you like, please feel free to weigh in with opinions
and/or concerns about the release process.

Thanks.

I'm delaying the pretest for a few days, because of Bug#2667, the
enable-character-translation issue, and a couple of other things.  Sorry
for the inconvenience.

The 23.0.94 pretest will be available shortly.  There was a minor
snafu---my internet connection died while I was uploading the tarfile to
ftp-upload.gnu.org, and now I can't continue uploading for some reason.
I've emailed the GNU webmasters for help.

The version number in CVS has already been bumped.

If anyone is interested I just happened to upload some unpatched
binaries for w32 to my site just after I saw this. (They are compiled
from the sources in CVS though, which was feteched after pretest
23.0.94 was announced.)

Now I suppose we are at "just before the 23.1 release".  Will the NS
port be marked as experimental/hackers-only, or given a title of
"first-class" port as a part of the official release?

Besides stability/performance issues found in the bugtracker, it still
has several compatibility issues as I mentioned earlier (I added new
comments in brackets in the following):

1. Different interface for existing functionality.

  a. ns-read-file-name vs. x-file-dialog
  b. ns-drag-{file,color,text} event + own handlers vs.
     drag-n-drop event + dnd.el
  c. ns-expand-space vs. line-spacing frame parameter
     [No longer an issue: the former was removed.]
  d. nsfont_make_fontset_for_font vs.
     :lang/:script/:registry properties in font-spec
     [The former is removed, and :lang/:script support was added, but
      :registry support is still missing.  The ns font-backend driver
      doesn't have the "shape" function for Complex Text Layout.]

2. Interface is the same, but implementation is based on own interpretation.

  a. tooltip (not being an Emacs frame, it cannot make use of Emacs
     display features such as images.)
  b. selection concepts (local/foreign selection, ownership)
  c. rightmost scroll-bar placement (it doesn't consider the case
     where scroll bars in different width, e.g., C-x 2 M-:
     (set-window-scroll-bars nil 11 t) RET)
  d. internal-border-width
  e. fringe and cursor drawing

3. NS-only implementation for features that are not inherently specific to NS.

  a. preferences panel
     [No longer an issue: removed.]
  b. alpha-component in color specification
     [Even without alpha, many formats in the NS port are incompatible
      with the other platforms.  The only compatible one is #rrggbb,
      which is not encouraged according to the X11 man page.  In this
      sense, it can also be classified as Group 1.]
  c. color image for stipple (cf. tiling patch by Miles Bader)
     [Even for monochrome images, "stippling" in the NS port is
      actually implemented as tiling rather than stippling.  In this
      sense, it can also be classified as Group 2.]

4. Suspected fundamental design flaw.

  a. C-g handling
  b. menu bar activation timing

I believe it is considered "first class port".  At least I do not think
it's "experimental".  [ Of course, the situation is completely
different for the GNUstep support ]

Yes, it still has a lot of room for improvement.  Help is welcome.
The points you raise all seem very relevant.  Maybe you should add them
in a new "Cocoa support" header in etc/TODO?

It's bad for the release version of the "first-class" port to keep
incompatible features that are to be removed/replaced later.  Maybe I
can help remove some of the incompatible features.

The long list of bugs (including crashes) suggests to mark it as  
experimental.  We currently don't have enough people who contribute  
fixes.  The port doesn't have release quality.
Note that the port doesn't build on the developer-releases of OS X  
10.6 (dumping fails), so it is likely that it won't build on 10.6 once  
it is out.

On the other hand, we don't want to discourage people to tinker with  
it since we want them to contribute code.  So it would be important to  
get it out there for people to use.

I've added notes to etc/NEWS, nextstep/README, and doc/emacs/macos.texi

other platforms.

Barring unforseen problems, I will make the 24.2.90 pretest next week,
Saturday the 24th.  Please plan your commits accordingly, thanks.

This is a good time to concentrate on bugs that ought to be fixed for
24.3 (mainly, regressions against 23.1+).  If you know of a bug that is
not receiving enough attention, please point it out.
