package-quickstart: How To Debug?

package-quickstart: How To Debug?

[T.V Raman]

I've been using  emacs with early-init.el containing (setq
package-quickstart t)
for a while now. All was well until last night when:

1. After updating packages as usual, all seemed well, but the next
   emacs restart failed  with a strange error.

   2. It errors out loading package-quickstart  with some error about
      marshall and eieio.

      3. If I remove the package-quickstart.el[c] files, and restart
         emacs, then emacs starts fine, since there is no
         package-quickstart to load I guess. However once that file is
         regenerated, the next restart of Emacs fails.

         Interestingly, loading the quickstart file after emacs has
         started successfully doesn't error out, i.e.

         A. remove package-quickstart.el[c]
            B. Restart emacs (with package-quickstart set to t)
               C. Either force the package-quickstart to be generated
                  by calling package-quickstart-refresh, or waiting a
                  while
                  D. In the still running emacs (load-file
                     package-quickstart.el) succeeds -- no errrors 

                     E. Now, kill emacs and restart --- emacs startup
                        fails.

Sounds like there may be a complication with byte-compiling
package-quickstart-file?  See the following emacs-devel thread and
commit.

Without more details it's hard to do anything about it.
A reproducible recipe, or at a least a backtrace would be welcome.
In any case I recommend you open a bug report for it.

What is package marshal and gb? I did a quick web search, for package marshal but I didn't found which packages that was. Is it in Elpa or elsewhere?

Hi, Raman!

I have installed all three packages, marshal, gh and gist, generated
quickstart file and byte compiled it and Emacs starts for me just as same.

When compiling marshal I have got some obsoloete/deprecated warning, but
Emacs starts just fine.

Interesting with gh; it uses old 'cl and uses lots of cl-* functions, so
when I start Emacs with gh in a version of Emacs I compiled from a
master I downloaded today, it just starts no questions asked. But in my
"normal" Emacs version, which is a native compiler branch about a week
or two old, I get some deprecated warnigns even with start. But aside
from that Emacs starts fine.

I see no crashes with byte compiled file at all. I don't know for Emacs
27 though; I don't have it installed.

Hope it helps.

Best regards
/arthur

Re: package-quickstart: How To Debug?

[T.V Raman via Emacs development discussions.]

Interesting. From what I remember, package-quickstart was bombing out
because of calls to eieio -- likely due to some macro expansion
error. I've worked around it for now by uninstalling marhsall and what
needed it --- given that Emacs is my primary/only environment for
geting spoken feedback without which I cannot work productively, I'm
not going to go chase this further --- Emacs not starting makes
things very hard :-)

Yes, I understand you. It is pain when Emacs does not start at all, I
hate it myself.

If Emacs does not start because of quickstart, you can always run it
with -Q or -q flags, so quickstart wont come into play.

But as said; I installed those and byte-compiled quickstart file and it
worked. So it can be something else in your setup. Or maybe just older
Emacs bombs out? Have you tried to build newer from the master?

Re: package-quickstart: How To Debug?

[T.V Raman via Emacs development discussions.]

The failure likely started after I built from master:-) I usually
build emacs once a day -- and it may well have gone away now --Arthur Miller writes:

It could also be an interaction between several packages, or god knows
what else.

T.V. if you can try and reproduce the problem on your side (e.g. by
re-installing those `marshall` and `gh` libraries) then maybe we could
use your generated `package-quickstart.el` file to reproduce the problem
on our side.

In those cases it can be helpful to start Emacs within Emacs
(e.g. within a term.el terminal).  I find it unusable in general, but
I've resorted to it on some occasions.

Re: package-quickstart: How To Debug?

[T.V Raman via Emacs development discussions.]

Yes, I've done this in the past too and  this is how I was able to say
that the error was being thrown by the marshall package and related to
eieio.

Unfortunately I've now fixed my world where the crash doesn't repro
which is why I cant send a backtrace.
