`macroexp--with-extended-form-stack` used manual push/pop so that upon
non-local exits the "deeper" value is kept, so the error handler gets
to know what was the deeper value, so as to be able to compute more
precise error locations.
Replace this with a `handler-bind` which catches that "deeper" value
more explicitly.
* lisp/emacs-lisp/bytecomp.el (bytecomp--displaying-warnings):
Use `handler-bind` to catch the value of `byte-compile-form-stack`
at the time of the error. Also consolidate the duplicated code.
* lisp/emacs-lisp/macroexp.el (macroexp--with-extended-form-stack):
Use a plain dynbound let-rebinding.
Move ad-hoc code meant to ease debugging of bootstrap (and batch mode)
to `top_level_2` so it doesn't pollute `signal_or_quit`.
* src/lisp.h (pop_handler, push_handler_bind): Declare.
* src/keyboard.c (top_level_2): Setup an error handler to call
`debug-early` when noninteractive.
* src/eval.c (pop_handler): Not static any more.
(signal_or_quit): Remove special case for noninteractive use.
(push_handler_bind): New function, extracted from `Fhandler_bind_1`.
(Fhandler_bind_1): Use it.
(syms_of_eval): Declare `Qdebug_early__handler`.
* lisp/emacs-lisp/debug-early.el (debug-early-backtrace): Weed out
frames below `debug-early`.
(debug-early--handler): New function.
* lisp/emacs-lisp/ert.el (ert--should-signal-hook): Delete function.
(ert--expand-should-1): Don't bind `signal-hook-function`.
(ert--test-execution-info): Remove `next-debugger` slot.
(ert--run-test-debugger): Adjust to new calling convention.
Pass the `:backtrace-base` info to the debugger.
(ert--run-test-internal): Use `handler-bind` rather than let-binding
`debugger` and `debug-on-error`.
* lisp/emacs-lisp/ert-x.el (ert-remote-temporary-file-directory): Don't
use `defconst` if it's not meant to stay constant (e.g. we let-bind it
in tramp-tests.el).
AFAIK, this provides the same semantics as Common Lisp's `handler-bind`,
modulo the differences about how error objects and conditions are
represented.
* lisp/subr.el (handler-bind): New macro.
* src/eval.c (pop_handler): New function.
(Fhandler_Bind_1): New function.
(signal_or_quit): Handle new handlertypes `HANDLER` and `SKIP_CONDITIONS`.
(find_handler_clause): Simplify.
(syms_of_eval): Defsubr `Fhandler_bind_1`.
* doc/lispref/control.texi (Handling Errors): Add `handler-bind`.
* test/src/eval-tests.el (eval-tests--handler-bind): New test.
* lisp/emacs-lisp/lisp-mode.el (lisp-font-lock-keywords):
Move 'handler-bind' from CL-only to generic Lisp.
(handler-bind): Remove indentation setting, it now lives in the macro
definition.
* lisp/emacs-lisp/comp.el (comp-delete-or-replace-file): Avoid
race condition by relying on 'rename-file' being an atomic
operation on Posix filesystems. (Bug#68083)
* lisp/emacs-lisp/checkdoc.el (checkdoc-this-string-valid-engine):
Avoid false positive when a variable contains a keybinding (for
example, "C-g"). (Bug#68002)
* test/lisp/emacs-lisp/checkdoc-tests.el
(checkdoc-docstring-avoid-false-positive-ok): New test.
The reason for warning about a missing footer line (";;; foo.el ends
here") is that package.el up until version 27.1 would refuse to
install a package without it. Emacs 27.1 or later will install such
packages, but will issue a warning, the purpose of which is to
encourage package authors not to break backwards-compatibility.
However, if the minimum required Emacs version for a package is 30.1,
we do not need to worry about compatibility with earlier versions of
Emacs -- the package author has already explicitly said that the
package will not work on earlier versions. For such packages, there
is no need to warn about a missing footer line.
In the future, this warning could be removed, but it is premature to
do that now. (See Bug#26490.) Thus, for packages that does not
specify a minimum version of Emacs, we continue to issue the warning.
We will also continue to warn for packages requiring Emacs 27 to 29,
since those versions will themselves warn if the footer is missing.
* lisp/emacs-lisp/package.el (package-buffer-info): Don't warn if the
footer line is missing for packages requiring Emacs 30.1 or later.
* lisp/emacs-lisp/package.el (package--prepare-dependencies): Move
from here...
* lisp/emacs-lisp/lisp-mnt.el (lm--prepare-package-dependencies):
...to here.
(lm-package-requires): New function.
(package-buffer-info): Use above new function.
* test/lisp/emacs-lisp/lisp-mnt-tests.el
(lm--tests-lm-package-requires): New test.
Reported by OGAWA Hirofumi.
* lisp/emacs-lisp/bytecomp.el (displaying-byte-compile-warnings):
Move most of the innards to...
(bytecomp--displaying-warnings): ...this new function, for ease
of maintenance.
* lisp/emacs-lisp/bytecomp.el (byte-compile-file):
Wrap early warning about missing lexbind declaration in
`displaying-byte-compile-warnings` so that it doesn't cause the
creation of a compile-log buffer with the wrong mode.
* lisp/emacs-lisp/bytecomp.el (byte-compile-toplevel-file-form)
(byte-compile-form):
* lisp/emacs-lisp/macroexp.el (macroexp--expand-all):
Use `macroexp--with-extended-form-stack` instead of explicit
push and pop.
Any non-trivial EIEO object in particular is impossible to read in the
*trace-output* buffer without this. Functions, hash-tables, etc now
print as they do in backtrace buffers.
* lisp/emacs-lisp/trace.el (cl-print): Require it
(trace-entry-message, trace-exit-message): Use cl-prin1-to-string
Let the caller tell us clearly where is the base of the backtrace,
if it's not `debug`. This is done by passing a new `:backtrace-base`
keyword argument to `debug`.
Then use this info systematically in all the places where we access
the real C-level backtrace, to try and avoid inconsistencies and brittle
code that tries to enumerate the expected frames we're in.
* src/eval.c (get_backtrace_starting_at): Add support for offsets in the
`base` argument.
(Fbacktrace_debug): Add optional `base` argument.
* lisp/emacs-lisp/debug.el (debug, debugger-frame, debugger-frame-clear):
Use `debugger--backtrace-base` when calling `backtrace-debug`.
(debugger-setup-buffer): Use `debugger--backtrace-base`
when calling `backtrace-get-frames`.
(debugger-frame-number): Drop `skip-base` arg, assume it's never nil.
Add sanity check.
(debugger--backtrace-base): Use the `:backtrace-base` info
in `debugger-args`.
(debugger-eval-expression): Adjust call to `debugger-frame-number`.
(debug--implement-debug-on-entry): Pass appropriate `:backtrace-base`.
* lisp/emacs-lisp/package-vc.el (package-vc--unpack-1): Wait for all
system operations to have been completed, before proceeding to remove
old package descriptors from 'package-alist'. This avoids loosing a
package if an error occurs during upgrades.
M-x eldoc is ElDoc's interactive entry point for on-demand
documentation for users that don't want the behind-the-scenes idle
timer behaviour.
However, eldoc-display-in-echo-area, a member of
eldoc-display-functions, refused to do anything because it thought it
didn't have permission to use the echo area, which isn't true
in interactive use cases. Fix that.

* lisp/emacs-lisp/eldoc.el (eldoc-display-in-echo-area): Use
INTERACTIVE argument. Rework comments.
(Version): Bump to 1.15.0
Quickstart can fail in all kinds of ways, for example if a package
was removed without updating the quickstart file.
* lisp/emacs-lisp/package.el (package-activate-all): Revert to the slow
path if the quickstart signals an error.
(package--activate-all): Fix compilation warning without an autoload.

* lisp/loadup.el: Disallow advices during preload. (Bug#67005)
Add ert-font-lock as well as unit tests and testing resources.
* lisp/emacs-lisp/ert-font-lock.el: New library.
* test/lisp/emacs-lisp/ert-font-lock-resources/broken.js:
* test/lisp/emacs-lisp/ert-font-lock-resources/correct.js:
* test/lisp/emacs-lisp/ert-font-lock-tests.el: Unit tests.

'cl--generic-prefill-dispatchers' to fix a build error.
This fixes bug#67483.
* lisp/emacs-lisp/byte-opt.el (byte-optimize-form): Push and

(shorthands--mismatch-from-end): Rework and document. Works like
