This (attached) approach seems to work in my manual testing. If you
like the general idea I can polish it off (try to make a test, etc.).
One thing that bothers me: because I fall back to
`package--activate-all' even package that successfully activate in the
quickstart file can have their activation code run twice, and they
aren't necessarily idempotent operations. Do you think this is a
significant problem?
One possibility is to update `package-activated-list' and
`Info-directory-list' incrementally in the quickstart file, so any
signaled errors leave `package-activated-list' mostly-correct. This
way, `package--activate-all' will attempt to activate only one package
twice -- the one that signaled from the quickstart file.

Subject: [PATCH] Make `package-activate-all' resilient to quickload errors.
If `package-activate-all' fails Emacs fails to start, so if
quickloading fails fall back to per-package activation. Note that
per-package activation already has logic to report package level
actiation errors with `message' and continue.

But that exposes the implementation of `geiser-activate-implementation`.
Copying the whole function definition to the autoloads file is "cleaner"
in this sense.

The GDB backtrace you got it from a time after the actual Lisp error was
caught, so you didn't get the relevant Lisp backtrace. If you put
a breakpoint on something like `Fsignal` you'd get something closer.
This said, it's still the case that the backtrace wouldn't show very
much info because the autoloads file is very "flat".

Ah! :-(

Don't do that. Help us improve `package-vc` instead :-)

Most largish packages do, sadly.

Kind of, but it's not very widely advertized (nor defined well enough to
be convenient to use) so it's a bit cumbersome and the actual
incantation used varies.
E.g. Hyperbole uses things like:
$(EMACS_BATCH) --debug --eval "(progn (setq generated-autoload-file (expand-file-name \"kotl/kotl-autoloads.el\") backup-inhibited t) (let (find-file-hooks) (hload-path--make-directory-autoloads \"kotl/\" generated-autoload-file)))"

--debug-init did nothing insofar as I could tell. Emacs behavior did
not observably change. It prints the following to stderr and exits with

Yes, I agree that the fix is suboptimal -- it was the smallest diff that
made the code do what it clearly intended to do.
I'm not sure I like your suggestion to keep using the
`geiser-activeate-implementation' function, because I don't think it is
because calling functions from "foo" without loading "foo" first is
confusing, and works only if they are defsubst (or macros). Is this
kind of thing commonly done in autoloads? Seems quite subtle.
I'd rather suggest that the gesier package autoloads simply not use the
helper function at all. Instead, just have the autoloads defvar
`geiser-active-implementations' and call `add-to-list' on it explicitly.
Seems simpler and unsurprising.

Yes, though see the backtrace above. It isn't very helpful, at least
for me, since the bottom of the lisp stack is the current
`command-error-function'.
Is this because the stack has already been unwound somehow?

Ah, ok. It looks like geiser's autoloads are hand written (and might
predate package.el), so an actual autoload for the defsubst ends up in
package-quickstart.el. See
https://gitlab.com/emacs-geiser/geiser/-/blob/master/elisp/geiser.el#L104
So, there is an extra level of indirection there compared to what
presumably a "modern" emacs package would do.
Yet, geiser wants to support use directly from downloaded source. What
is our current suggestion for packages that want to ship their own
pre-canned autoloads? Do you know of a package supporting this without
resorting to hand edited autoloads? I assume there is some canonical
'emacs -f batch_blah_blah' but, maybe not?

FWIW, that's a rather poor fix, since it causes `geiser-impl.el` (and
the files it requires) to be unconditionally loaded during
Emacs startup. The better fix would be to make sure the
`geiser-active-implementations` itself gets initialized before the calls
to `geiser-activate-implementation`.

I think it's a good idea to do that on `master`, indeed.

Agreed. I suspect it should also do things like delete the `.elc` file
(and/or the `.el` file), or at least suggest doing it, so as to help
diagnose/circumvent the problem.

In the case of `--debug-init` it could at least print the backtrace on
`stderr`. Or store the backtrace and display it later (even though the
debugger wouldn't be active, it would still be nicer to manipulate than
when sent to stderr).

We could probably use `(setq load-file-name ...)` between file chunks
(instead of `let` binding the var) and wrap the whole file with
a `condition-case` which then prints the "current" `load-file-name`.

It works. It just works differently (it copies the whole `defsubst`
instead of placing an `autoload` statement). AFAIK byte-compiled or not
doesn't make much difference in this respect.

My hope for this bug is to explore, and possibly implement, improvements
to Emacs that make it more robust against the class of bug I describe
below. I'm looking for input from people with more knowledge/experience
with Emacs packaging, and especially `package-quickstart' (hence +CC
monnier@)
General description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
It is possible to "brick" your emacs if `package-quickstart' is t and
there is a packaging bug in something you install. By "brick" I mean
Emacs does not launch, but prints a potentially useless error message to
stderr and exits with 255 error code.
I was able to diagnose and fix the offending package, but only after
spending too much time debugging, and resorting to running Emacs through
gdb and disassembling compiled .elc files.
Note that in this case the upstream packager was just as mystified as I
was as to what the problem was, and the upstream bug was many months old
before I finally diagnosed and fixed it. Because it happened only with
(setq package-quickstart t) a minority of users were seeing the problem.
Specific description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
One instance of the issue is here:
https://gitlab.com/emacs-geiser/geiser/-/issues/47
The one line fix is here:
https://gitlab.com/emacs-geiser/geiser/-/merge_requests/13/diffs?commit_id=
=3Dca0407bc942d3cae5ff1ae0bd966311b425d9a86
I will summarize the repro step here, though the steps no longer work
because the package has been fixed:
1) set `package-quickstart' to t in both init.el and interactively.
2) M-x package-install RET "geiser-guile"
3) quit emacs
4) launch emacs
With this, emacs fails to launch, instead printing:
Symbol=E2=80=99s value as variable is void: geiser-active-implementatio=
ns
The root problem was that `geiser-activate-implementation' was a
defsubst, not a defun, yet it was autoloaded, which makes no sense
because it is expanded inline in byte code, and thus won't load its
original package. Here is an edited down version of what ends up in my
~/.config/emacs/package-quickstart.el after installing `geiser-guile':
(let ((load-true-file-name "/home/matt/.config/emacs/elpa/geiser-0.28/g=
eiser-autoloads.el")
(load-file-name "/home/matt/.config/emacs/elpa/geiser-0.28/geiser=
-autoloads.el"))
(autoload
'geiser-activate-implementation
"geiser-impl"

(geiser-activate-implementation 'guile)
(provide 'geiser-guile-autoloads))
The code for `geiser-activate-implementation' was originally:
(defsubst geiser-activate-implementation (impl)
(add-to-list 'geiser-active-implementations impl))
So the `(add-to-list 'geiser-active-implementations 'guile)' ended up
inlined into "package-quickstart.elc", which executed directly, without
first (auto) loading 'geiser-impl' as was intended. Thus, the
`geiser-active-implementations' variable did not exist, yet was
referenced, by inlining, but did not appear textually in
package-quickstart.el.
Once understood obvious fix to make geiser-activate-implementation a
defun instead of a defsubst.
Ideas for improvement (also seeking ideas from others)

0) Make `package-quickstart t' the default, because it is great, and
that way people tend to see the same kinds of problems. :-)
1) Harden Emacs such that signaled errors from "package-quickstart.elc"
don't prevent startup (but are somehow saved and logged, maybe as
warnings?).
2) Make --debug-init functional for errors thrown by
"package-quickstart.elc". Currently, package-quickstart is loaded
before the first frame is initialized, so Emacs takes the "print the
error and exit" route for any signaled errors, instead of, for example,
ending up in the elisp debugger.
3) Perhaps package-quickstart.elc could be loaded later in the
initialization phase, after the first frame is created? ...though I
suppose it is nice to load packages that are themes before the first
frame is created...
4) Perhaps if loading package-quickstart signals an error it can be
ignored and the slow path can be taken instead?
5) Change "package-quickstart.el" code gen to provide more context for
errors, perhaps with `condition-case-unless-debug'. The jwigley's
use-package package does something similar in its macro expansions and
it is nice. In the specific case with the geiser packages, because
Emacs exited immediately, it would have been useful to know that the
error came from the "geiser-guile-autloads" portion of
"package-quickstart.elc". Currently there is no backtrace to speak of
because "package-quickstart" is so flat.
6) Print a warning when a `defsubst' function is autoloaded, as the
autoload won't work from byte compiled code.
