bug#14704: 24.3.50; cl-lib breaks built-in Emacs version

[Sebastian Wiesner]

"(require 'cl-lib)" breaks the Emacs version information for
package.el.  In "emacs -Q", "M-x ielm":

ELISP> (package-initialize)
t
ELISP> (package-built-in-p 'emacs (version-to-list "24.1"))
t
ELISP> (assq 'emacs package--builtin-versions)
(emacs 24 3 50)

ELISP> (require 'cl-lib)
cl-lib
ELISP> (package-built-in-p 'emacs (version-to-list "24.1"))
nil
ELISP> (assq 'emacs package--builtin-versions)
(emacs 2 2)

This breaks dependency resolution for packages which depend against a
certain Emacs version.

These incorrect entries in package--builtin-versions come from
"cl-loaddefs.el", which contains two instances of the following line:

(push (purecopy (quote (emacs 2 2))) package--builtin-versions)

These lines are apparently extracted from the package headers of
"cl-macs.el" and "cl-seq.el" which look like the following:

;; Author: Dave Gillespie <daveg@synaptics.com>
;; Version: 2.02
;; Keywords: extensions
;; Package: emacs

This meta information is obviously wrong.

This is the 3rd critical package.el bug I discovered within just a week
or so.  Don't you test your code?!

If you want well-tested code, stay with Emacs official releases. If
you compile from trunk, expect breakages, untested code and potential
data loss. Caveat user.

Who would test your code then before releases if not those who compile
from trunk?  You developers obviously don't…  and what is worse, you
apparently do even *care*.

These three bugs I found are so blatantly obvious and so severe that
even the most sloppy manual testing, let alone unit testing, would
have revealed them, but all you have to say to such a bad failure is
“Boy, this is trunk, go home to mama, and play with old releases”?!

I am sorry that you do not know about CI, unit testing and software
quality, but I do, and thus I am horrified by the neglect and
ignorance you demonstrate in developing one of the most important
tools of my daily work.

Yes, users (and developers) test it. Users file bug reports. Sometimes
they offer a patch, often they don't. That's fine and good. Users
don't usually come screaming and demanding. That seems rude, to say
the least.

No, more like "go home to mama and ask her again about good manners".

Not sure if that you is singular or plural. It's wrong in either case.

If I were a usual user, I would just have gone back to a release as
you said.  After all, your bugs and your lack of software testing are
not my problem in the end.

But instead I did you work: I debugged the problem, found the cause,
and reported it.  I am sorry that I did not provide a patch right
away, but I am unfamiliar with your code base, and have not signed any
copyright papers and no intention whatsoever of doing so.  I doubt
that any patch of mine would have been accepted.

I did neither scream nor demand, but I actually expected you to apply
care and attention to your work.  I write tests for my own code, and I
run them, and I expected you to do so as well.  I see now, that you do
not, which is embarrassing to you and very ignorant towards your
users.

By not writing or running tests for *your* code you have wasted *my*
time.  That is what I call “rude”.

Fine, let's go home than.  I'll ask ma about good manners, and you'll
ask your high school teacher about software testing.  We'll see who of
us learns more on this trip…

Out of fairness, you found 3 bugs in a single 1700-line package, and
made very far-fetching conclusions ("Don't you test your code?!") out
of that.  Emacs weighs in at 400K C lines and 1400K Lisp lines, so
with all due respect, accusing us in not testing our code based on
such a small sample is a bit too much.  If all that code were not
tested at all, it would never have worked at all.

These three bugs weren't just stupid forgotten corner cases in some
remote and obscure feature that none uses.  They broke an essential
command—which worked well before—in a very obvious and very bad way.

These bugs should have been caught by testing before making a commit.
But they weren't, so in this specific case, I think I can quite
legitimately conclude that these specific changes were not tested at
all, or only very carelessly.

I understand that package.el is being refactored currently, but that
isn't an excuse imho.  On the contrary, every software development
course teaches about making refactorings in a separate branch and
never without unit tests.

But I admit that I should not have generalized this statement, and I
apologize to you and to everyone else whom I offended.

> If all that code were not tested at all, it would never have worked at all.

It is tested, for sure, but probably less by you, and more by your users.

It is tested both by developers and users.  Emacs has a myriad of
features, some of which are not even documented clearly.  No matter
how well and long one tests their own code, they can never test it in
all the possible combinations with the other features and use cases.

As for "less by you", please be careful, because someone might take
offense again.  E.g., I have a large body of unit tests for display
features, such as cursor positioning, which I run by hand every time I
touch any of the related code.

Do you feel like adding it to the repo?
Sounds like it would be useful to have in test/, even if not suitable
for test/automated/.

Who except myself would want to run, let's see... about 30 tests, by
hand, first in a GUI session, then in a TTY session?

Even if no one else would do that for now (I have no idea), sometimes
things happen, you know. Bus factor and all that.
I'm sure anyone else working on the display engine would find a suite of
tests helpful.

Of course, if you were able to automate them to some degree, that would
be even better.

Fine.  I will add them one of these days.

We lack a lot of infrastructure for that, like access from Lisp to
data structures manipulated by the display engine.  If I were to write
all that, I'd probably have no time left for development and fixing
bugs.  It would be a fine exercise for someone who'd like to learn the
display engine internals, though, so motivated people are welcome...

What kind of API are you envisioning? Yes, I know that a designing a
precise API is half the work, I'm asking more about the general idea.

First, a caveat: I didn't really put a lot of thinking into this.

That said, what I had in mind was an API that would return a detailed
description of the current glyph matrix for a window.  Another API
should return the position and description (block, bar, hollow, etc.)
of the window's cursor.

Another useful feature would be to be able to produce the full
sequence of calls to display-specific back-end APIs which were
involved in a given redisplay cycle.  This would obviously require
design of some kind of language to describe these sequences.

There will be probably more once we start on this road, but the above
should be a good starting point, IMO.

For the tty case at least we could image just use the sequence of bytes

True, but even TTY output is to some extent dependent on the terminal
capabilities, so parsing such byte streams is not entirely trivial.

Definitely not trivial, but we can control the terminal capabilities
(e.g. using a hand-crafted terminfo file).

I'm still plagued by display errors on one of my machines @ work. I

Since I don't know what kind of display errors you are having, it's
hard to answer your question.  The tests I was talking about exercise
the code in Emacs which moves and positions cursor triggered by cursor
motion commands, such as C-f, C-n, etc.

See the appended screenshots, reading your message in gnus. The first is
opening the message (looks OK), the second one is after entering <space>
in the summary buffer. You see the ">" char in column 1.

It is a fresh Emacs build of today.

Weird.  This is different from what you described before: here, only a
part of a line is left un-updated.

Do you see anything like that in modes other than Gnus?  Any chance of
a simple reproducing recipe?

This is, because it is at the end of the buffer. Usually, we shall see
nothing there; but we see the wrong character in the first column.

The other behaviour I've reported is still evident.

On that machine it happens often, mostly when there is pageup/pagedown.
It's not restricted to Gnus; it could happen in any buffer. Meanwhile, I
am used to apply mwheel-scroll whenever it happens; the redisplay makes
the buffer readable.

Since this is the only machine where it happens, I feel helpless giving
you a simple recipe. The better way might be that you give me a special
patch producing whatever traces could help in analysis.

Best regards, Michael.

If it happens only on that machine, can't it be some local hardware or
system software problem?

I will try to think about it.  Could just summarize what
idiosyncrasies do you remember seeing on that machine?  Like in which
parts of the display/window do these artifacts appear, and which
part(s) of a line did you observe garbled?  E.g., is it always the
beginning of a line?

Maybe. The machine runs "Tubuntu 12.04", which is an Ubuntu bundle from
my employer. But I haven't seen other anomalies on that machine, and
most of the packages are native Ubuntu ones. The differences are mainly
user policy and alike.

I'll see whether I could find another Tubuntu machine, and cross-check
whether it is a hardware problem. The problem is that Tubuntu is not
widespread (managers are focussed on MS Windows, and they rule); I don't
know whom to ask here at Berlin. But there is a company-wide Tubuntu
mailing list ...

I'll check tomorrow more systematically.

Eli, if you look at the image included in this bug report, this looks
like the same display bug that I've seen a few times.  It's as if Emacs
isn't clearing some parts of the screen when scrolling.  (Sometimes.)

I still haven't been able to make a test case for this.  It happens to
me like a couple of times a week, so it's pretty obscure...

Probably some redisplay optimization that doesn't exactly DTRT.

When this happens, does it help to type "M-x redraw-display RET"?  If
it does, then, in the absence of a reproducible test case, all I can
suggest is gather more info to narrow the range of possible
offenders.  Start by rebuilding Emacs with -DGLYPH_DEBUG=1, then start
Emacs with stderr redirected to a file, toggle redisplay tracing with
"M-x trace-redisplay RET", and wait till the problem happens.  When it
does, make the window with incorrect display the currently selected
window, and type "M-x dump-glyph-matrix RET".  Finally, send the
contents of the redirected stderr here.

There are also several variables that inhibit certain redisplay
optimizations.  They are defined in xdisp.c and are available only
when Emacs is compiled with -DGLYPH_DEBUG=1:

  #if GLYPH_DEBUG
    DEFVAR_BOOL ("inhibit-try-window-id", inhibit_try_window_id,
		 doc: /* Inhibit try_window_id display optimization.  */);
    inhibit_try_window_id = 0;

    DEFVAR_BOOL ("inhibit-try-window-reusing", inhibit_try_window_reusing,
		 doc: /* Inhibit try_window_reusing display optimization.  */);
    inhibit_try_window_reusing = 0;

    DEFVAR_BOOL ("inhibit-try-cursor-movement", inhibit_try_cursor_movement,
		 doc: /* Inhibit try_cursor_movement display optimization.  */);
    inhibit_try_cursor_movement = 0;
  #endif /* GLYPH_DEBUG */

By selectively turning off each of these optimizations, we could zero
in on the optimization that causes this bug.  However, using these
variables effectively needs some initial ideas about the possible
causes, so I think gathering the info as suggested above is best as
the first step.

Thanks for the recipe; I'll do this the next time I see this redisplay
glitch.

Unfortunately, I hadn't compiled Emac with -DGLYPH_DEBUG=1 (but am going
to do it now), but at least I managed to take some screen shots now,
which may give somebody an idea about what the problem is, perhaps.

(Sorry for the big email.)

The first image is me reading a blog post normally.  The second is me
typing `C-h f redisplay'.  Only the top half of the display is actually
refreshed, leaving the image apparently being displayed in the help
buffer.

And the last image is me lowering and raising the window, forcing a
redisplay, which makes Emacs look like it should again.

Is this reproducible, e.g., with that blog post?  I've seen in the
past redisplay problem with images, but they would disappear in a
fresh session of Emacs, even if I made exactly the same gestures as
the ones which reproduce the problem in a long-running session.  Do
you have the same experience?

When you do have Emacs built with -DGLYPH_DEBUG=1, and this happens,
invoke "M-x trace-redisplay RET", and tell what it prints to stderr
when you do whatever is needed to reproduce the problem.

Nope.  After refreshing the display once, it doesn't happen again.

I'd say that it happens about, er, once a thousand times that Emacs
displays a message, and it's totally unreproducible.

I *think* what happens is always that this only happens when I scroll
the buffer down and it reaches the end.  After the end of the buffer,
the bottom of the window should be totally blanked out, but sometimes
(if there's an image in the part that should have been blanked out after
scrolling), it doesn't happen.

So my feeling is that there may perhaps be an optimisation relating to
clearing the window after end-of-buffer.  But that may be totally wrong,
of course.  :-)

I'm now running with GLYPH_DEBUG and STDERR to a file, so I should be
able to get a trace the next time...

I've also seen it happen in the middle of a buffer, ie. the image is
half overwritten by the new text, but the blank area after eol is not
cleared.

bug#10304: 24.0.92: display bug

[Lars Magne Ingebrigtsen]

Ok, I got a display bug, and it was of the same time as before: After
scrolling, area after the end of the buffer wasn't cleared, leaving the
image.

I switched on trace-redisplay, paged back and forth, which was still
buggy, and then did a matrix dump.

Then the window fixed itself suddenly without me doing anything.

Here's the output from the log file.

Thanks.

Does the trace you posted include the time when the window
fixed itself, and if so, can you try identifying in the trace the
place where it happened?  Could it be here:

  expose_frame (796, 696, 24, 484)
  expose_window (796, 696, 24, 464)
  expose_window (796, 1160, 24, 20)

I will study it, but it is important for me to understand how this log
is related to whatever you did in Emacs.  Does this reflect only the
"page back and forth, and the matrix dump", or does it include more
stuff?

I had switched to an xterm that was partially overshadowing the Emacs
frame, and typing away in that xterm.  And then suddenly the Emacs frame
updated itself and everything was OK.  So I'm not sure how that relates
to the blog, but it was after the glyph dump, at least.

What I did was read the message (from the *Summary* buffer), hit SPC,
and the *Article* buffer scrolled forwards and had the wrong display.

Then I jumped to and xterm to read the instructions I had saved in a
file there.  Then I think I went back to the Emacs frame, typed `M-x
trace-redisplay', scrolled back and forth (with the bug still
displaying), then did a dump-glyph-matrix, then went back to the xterm,
and then Emacs spontaneously fixed itself, and then I went back to the
Emacs frame and switched the trace off.

I think.  :-)

By the way, perhaps the trace log should have timestamping on the lines
to be able to match it up more easily to user actions?

What would you compare those time stamps with, to find out what trace
corresponds to which user action?

In this case, the pause in actions would presumably correspond to me
typing away in the xterm, for instance.

According to this, the window had 70 lines, of which 43 displayed
text; that text was comprised of empty lines, except for the 2nd line
which displayed the text "Link "; and point was on that 2nd line.
Does that sound reasonable?

Btw, next time please use (dump-glyph-matrix 2), to get more
information about the glyphs on display.

Yes, the only text in the buffer was the Link thing, and that was
probably on the second line.  However, the window was (let's see) 43
lines tall.

The image was (faultily) displayed right below the Link.

Will do.

OK, that's my misreading of the dump: the "(0)" part means the line is
disabled in the glyph matrix, i.e. not displayed.

> The image was (faultily) displayed right below the Link.

So the bug seems to be that we don't clear those empty lines which
occupied the screen estate of the image.  Hmm...

Also, I just installed a few changes on the emacs-24 branch that make
the matrix dump better, please resync if you can.

Could you describe in more detail what happened to cause the text at
the end of the buffer be displayed instead of the image?  Is it that
the buffer included an image and also some text, and that buffer was
scrolled such that the image went out of view and the text came into
view?  Or was it some other scenario, like maybe switching buffers in
the window?

Andreas, perhaps you also could give such details about your case?

I think I see the code that could be the culprit, but I need to
understand better how the new display replaced the old one, to dig
deeper.

TIA

I had a beautiful example of the bug last night, but I fumbled and make
the window go away before I could get a screen shot.

And the redisplay log was truncated because I had started two Emacsen
pointing to the same file.  *sigh*

Anyway, here's the bits I could salvage from the log, and a glyph dump.

To explain what happens is that I have a window that has an image in
it.  When I then scroll the buffer forwards, so that the window displays
the end-of-buffer, and the image occupied (visually) part of the window
after the end-of-buffer, then the rest of the window isn't blanked.

Ok, that explanation didn't make much sense.

I'll try to draw.

Here's what the window looks like first, when everything is OK:

-----------------------------
| bla bla bla               |
| bla bla bla               |

| bla bla                   |
| bla bla                   |
-----------------------------

Then I scroll.

-----------------------------

And the buffer ends where it says.  :-)

So I get the bottom half of the image, and then whatever was after the
image.

So it's like it decides that it doesn't have to blank the window after
end-of-buffer if end-of-buffer happens in the middle of the image that
was displayed there.  If you understand what I mean.  :-)

I think I do understand.  My suspicion is that we somehow fail to
realize that the screen estate formerly occupied by the image, and
everything that follows it, needs to be cleared in its entirety.  On
the display engine level, the image takes just one "line" (called
"glyph row"), and perhaps we somehow don't realize that the height of
that "line" is large, and all of that needs to be cleared, not just
the number of text lines of "normal" height that will replace the
image on display.

Thanks for the details, they confirm my suspicions.  I now need to
find whodunit in the code...

If you need more data: on one of my laptops I can easily reproduce this
bug. Just tell me, whether I shall produce more debug info for you.

Best regards, Michael.

What I'd really like is a reproducible recipe.  Can you come up with
one?

Nothing general. I'm in the bad situation, that one of my laptops (at
work) produces the display bug permanently. Often, just scrolling or
page up/down is sufficient. That Emacs stanza is almost useless for me,
but there's no recipe for reproducing outside that machine.

Maybe we could arrange that I take it home, and provide you access. Over
night, or over weekend. Let me know.

Best regards, Michael.

Weekend is better, thanks.

Please apply the patch below and run with it for a while.  It makes
the output of trace-redisplay more voluminous, but I don't see how
else we could catch the problem.  When the problem happens again,
please post the results.

Here's my analysis of what is involved; perhaps it will help you read
the output and make some changes on the spot, if needed.

The clearing of portions of display that no longer display anything is
done as part of dispnew.c:update_window.  It does that as part of the
call to update_window_line, when the latter is passed a screen line
(a.k.a. "row") that should be empty on display.  Such empty lines have
a single glyph (an "invented" blank character with charpos equal to
point-max), whose sole purpose is to facilitate clearing of empty
lines.  These empty lines have the enabled_p flag set, which means
they should be displayed.  (update_window ignores lines whose
enabled_p flag is reset, because these do not correspond to any part
of the displayed text.)

So, for us to fail to clear these empty lines, I see several possible
reasons:

 . the logic in update_window somehow skips the loop that starts at
   line 3495 and which displays the empty lines past the end of the
   buffer; or

 . some redisplay optimization in xdisp.c decides that those parts of
   display do not need to be updated, and thus excludes them from the
   glyph matrix it constructs in w->desired_matrix, so that those
   lines are not updated by update_window; or

 . the function x_clear_end_of_line, which is called by
   update_window_line, or its terminal-specific back-end (e.g.,
   xterm.c:x_clear_frame_area), which implements the meat of that
   function, somehow fail to clear the correct portion of the display.

The patches below are designed to report enough info for us to be able
to tell which of the above hypotheses, if any, is true.

Btw, any idea when these problems started happening?  Is it an old
problem, or did it start to appear only recently?

Thanks.

I have applied the patch, and I have also compiled Emacs trunk with
-DGLYPH_DEBUG=1. When the problem happened, I have taken a screenshot,
and I have evaluated (dump-glyph-matrix 2)

See the appended screenshot.jpg. It is an older email from Lars about
the topic (message-id <m3sj6gyqhj.fsf@stories.gnus.org>, from "Sat, 05
Jan 2013 09:38:00 +0100"). At the bottom of Emacs, you see 3 lines which
are scrambled. Besides the screenshot, I have also appended the dump of
Emacs. HTH.

> Thanks.

Best regards, Michael.

Did you get any further on this?

I've finally found a single message in Gnus where I can reproduce this
almost 100% of the time -- but only on this display, so it's probably
closely tied to the exact geometry of the Emacs frame.

But if you have debugging instructions, since I can now reproduce this,
I can hopefully give you the output you need to fix this...

No.

Can you run with the patch I posted back then, and report the output,
together with a screenshot of the offending display corruption (so I
could match the debugging output with what was on the screen)?

Will do.  I'll try to get it done tomorrow.

D'oh.  I dumped the glyphs in the wrong buffer.

I'll do another one.

Sorry for a long delay.

Unfortunately, I cannot match either of your two images with the
corresponding dump of the glyph matrix: there are small
inconsistencies in both the "OK" and the "not OK" cases.  For example,
the first image shows "Top L1" in the mode line of the window that
displays the article, but the matrix dump says:

 68: (1) ' 1:---  . news:g.c.w.arnoldzwicky Austenian humbleb...   Top L19    (Article)    '

which is line 19.  This is a minor discrepancy, but since there are
many similar discrepancies, some of which are probably parts of the
bug, I feel I have no firm ground from which I can begin studying the
data and making hypotheses about what went wrong.

Could you please produce 2 sets of screenshot+matrix dump which are
coherent with each other?  I must be sure that when I see a
discrepancy, it is part of the bug, not some artifact that needs to be
ignored.

Also, I don't understand the second screenshot: which parts of it are
correct and which are bogus?  The text before the image looks
unfinished, but its continuation, starting with screen line 20, which
is clearly present in the glyph matrix dump, is not shown.  Are you
saying that Emacs was supposed to display that continuation, but never
did, and instead left the old parts on display?

Thanks.

Thanks, and sorry again for a _really_ long delay.

Based on the stuff you collected and the screenshots, it sounds like
Emacs doesn't clear and doesn't redraw the parts of the screen which
become corrupted, amazing as that sounds.  The only difference between
the "good" and the "bad" output is that in the latter case, for some
reason, Emacs stops clearing and redrawing screen lines below some Y
coordinate, and all the stuff which was there before that stays put
instead of being replaced by the new stuff.

I'd like to prepare an additional patch which will allow you to
collect more data that might reveal why Emacs behaves like that.  In
order to test the patch, is it possible for you to give me
instructions for how to display that article, starting from "emacs -Q"?

Thanks in advance.  I think we are making progress, albeit slowly (my
fault, not yours).

That was easier than I had thought.  I had forgotten about this entry
point to Gnus.

`eval'-ing this from "emacs -Q" should work:

(gnus-fetch-group "nntp+news.gmane.org:gwene.com.wordpress.arnoldzwicky" '(3401))

although you will be queried about the self-signed certificate.

Thanks, that was easy enough.  Granted, I don't see any redisplay
problems with that article, like you do.

Below please find a new patch to add trace data.  This is _instead_ of
the previous patch, not in addition to it, and it's relative to the
current master (I hope the problem is still visible with the current
master).

After applying the patch, please again do whatever is needed to
reproduce the problem, and please tell me which part(s) of the trace
are emitted when the display becomes corrupted.

Before invoking "M-x trace-redisplay", please disable
blink-cursor-mode (as it triggers too many unnecessary redisplay
cycles that muddy the water), and also delete ("C-x 0") the summary
window, so that redisplay has less windows to refresh (which will
again make the signal to noise ratio of the trace better).

Thanks.

Could you perhaps see if this bug still exists in the latest master?
It's possible that the changes in commit d89687b fixed it.

Bisecting my ~/.emacs, the following form provokes the display error for me:

(add-to-list 'default-frame-alist
             '(font . "-misc-fixed-bold-r-normal-*-15-*-iso8859-1"))

On other machines, there is the same ~/.emacs w/o problems. On the
machine in question, I have two matching fonts:

-misc-fixed-bold-r-normal--15-120-100-100-c-90-iso8859-1
-misc-fixed-bold-r-normal--15-140-75-75-c-90-iso8859-1

Does this tell you anything?

Not really, unfortunately: I know very little about fonts and how
Emacs uses them.

But if we continue your line of investigation: does removing one of
these fonts solve the problem with the original ~/.emacs?

It happens for both fonts. I've tested 

(add-to-list 'default-frame-alist
             '(font . "-misc-fixed-bold-r-normal--15-120-100-100-c-90-iso8859-1"))

and

(add-to-list 'default-frame-alist
             '(font . "-misc-fixed-bold-r-normal--15-140-75-75-c-90-iso8859-1"))

Anyway, here is a recipe for reproduction:

1. C-x C-f "a larger file, with a no space in last line, first col"
2. M->
3. C-p
4. Use mouse wheel to scroll buffer up

It doesn't happen always, but often. Depends on redisplay calls, I
suspect. See enclosures, which show a superfluous "(".

I tried to reproduce this, including installing and using a misc-fixed
font, but couldn't see any such artifacts left after scroll.

Do you see the problem with these fonts on a different system?

Does anyone else see this?

Nope. I see it only on this laptop @work.

If you have an idea for instructing the display engine with trace
messages, just tell me. Or how to debug.

Best regards, Michael.

Until 10 lines or so, they could be accepted if they fix the bug and
are clearly written, as a "tiny change".

" Don't you test your code?! " counts as a scream and a demand in my view.

Your definition of "rude" seems quite one-sided.

Let's try not to turn this into a high school match...

Im sorry I wasted your time, but do note that all the time I put into
breaking Emacs (and package.el more recently) is purely my own leisure
time, so I'm very happy not to have to follow too strict procedures.


        Stefan "who'd have been happier not touching package.el at all,
                since he never uses it and doesn't even know half of the
                expected use cases, which makes writing tests that much
                more interesting."

Each release is preceded by a long pretest period, when we are trying
to collect usage experiences from as many different platforms and
users as possible.

I don't think this is a fair comment.  A released version is more
stable than a development snapshot, that's a fact.  It has nothing to
do with caring or not.  It also doesn't only happen due to more
testing: during a pretest, only bugfixes are allowed into the code
base, so potentially destabilizing changes are avoided.

While more testing is always a good thing, some areas in Emacs are
hard to test.  Please consider coming on board and moving Emacs closer
to the CI ideals and testability.  TIA.

I know.  I was upset by his comment, and I still am, but I should have
taken a deep breath before replying.  I meant no offense, and I am
sorry.

package.el isn't such an area.

I am sorry, but I won't, for two reasons: Bazaar, and copyright assignments.
