* lisp/emacs-lisp/edebug.el (edebug-remove-instrumentation):
Prompt the user for what functions to remove instrumentation from
a la cancel-edebug-on-entry (bug#38195).
* lisp/emacs-lisp/edebug.el (edebug-eval-last-sexp): Make the zero
prefix work analogously to in eval-last-sexp (bug#28895).
(edebug-eval-print-last-sexp): Ditto.
* doc/lispref/edebug.texi (Breakpoints): Document this.
* lisp/emacs-lisp/edebug.el (edebug-disabled-breakpoint): New face
(bug#23472).
(edebug-enabled-breakpoint): Rename.
(edebug--overlay-breakpoints): Use the new face.
(edebug-toggle-disable-breakpoint): New command and keystroke.
* lisp/emacs-lisp/edebug.el (edebug--recursive-edit): Bind
minor-mode-overriding-map-alist to avoid other minor modes hiding the
edebug commands (bug#11018).
* lisp/emacs-lisp/edebug.el (edebug--overlay-breakpoints)
(edebug--overlay-breakpoints-remove): New functions (bug#23468).
(edebug-modify-breakpoint): Use them to highlight breakpoints.
(edebug--display-1): Restore breakpoint highlights.
(edebug--recursive-edit): Remove highlights on exit.
* lisp/emacs-lisp/edebug.el (cancel-edebug-on-entry): Add doc
string and make the interactive spec complete over functions that
have the spec (bug#10806).
(edebug-cancel-edebug-on-entry): Add alias for discoverability.
(edebug-on-entry): Clarify what this command does.
* lisp/emacs-lisp/edebug.el: (nested-backquote-form): a new edebug-spec which
handles nested backquote structures without a , or ,@ "between" the outer and
inner backquotes.
(backquote-form): Use nested-backquote-form.
* lisp/emacs-lisp/edebug.el (edebug-clear-coverage): Use
edebug-unknown and edebug-ok-coverage instead of unknown and
ok-coverage to avoid naming collisions with packages that use
those two symbols (bug#25471).
(edebug--update-coverage, edebug-display-freq-count): Ditto.
Restore lines saying "Maintainer: emacs-devel@gnu.org" when there is
no special maintainer for a file. Although this wasn't documented
it was common practice and removing the lines didn't have consensus.
* lisp/emacs-lisp/bytecomp.el (byte-compile-setq-default): Delete.
(byte-compile-set-default): Inline the part that it used.
* lisp/emacs-lisp/edebug.el (setq-default): Remove the debug spec.
* src/data.c (Fsetq_default): Delete.
(syms_of_data): Don't register.
* lisp/emacs-lisp/edebug.el (edebug-print-length)
(edebug-print-level): Fix customization type to allow setting
the documented valid value nil via the Customize interface.
Thus when entering edebug, the focus will be moved to the frame with the
source being debugged, and when its finished, the focus will move back.
Commands edebug-visit-eval-list (`E') and edebug-bounce-point (`p') have been
likewise amended.
* src/keyboard.c (readable_events): Handle FOCUS_OUT_EVENT as an invisible
event. This prevents input-pending-p returning t when one of these events
arrives, and thus obviates an instant termination of sit-for when there's no
"real" event waiting.
* lisp/emacs-lisp/edebug.el (edebug-focus-frame): New function.
(edebug-default-enter, edebug--display-1, edbug-where, edebug-bounce-point)
(edebug-visit-eval-list): Call edebug-focus-frame to move focus into the
window newly selected by edebug-pop-to-buffer.
I looked through all instances of most-negative-fixnum
and most-positive-fixnum in the Lisp source code, and
when it was easy I removed assumptions that integers
fit in fixnums. The remaining instances are either
nontrivial to fix, or are inherent to the algorithm.
* lisp/arc-mode.el (archive-l-e): Do not convert to float,
since we have bignums now. All uses changed.
* lisp/calc/calc.el (math-bignum):
Don’t special-case most-negative-fixnum.
* lisp/calendar/parse-time.el (parse-time-string):
* lisp/emacs-lisp/edebug.el (edebug-read-special):
* lisp/emacs-lisp/package.el (package--remove-hidden):
* lisp/gnus/nnfolder.el (nnfolder-read-folder):
* lisp/international/mule-util.el (filepos-to-bufferpos--dos):
* lisp/menu-bar.el (menu-bar-update-buffers):
* lisp/net/rcirc.el (rcirc-handler-317):
* lisp/org/org-agenda.el (org-cmp-ts):
* lisp/window.el (window--resize-child-windows):
Avoid arbitrary limit to most-positive-fixnum or to
most-negative-fixnum.
* lisp/calendar/time-date.el (days-to-time):
* lisp/erc/erc-dcc.el (erc-unpack-int):
Don’t worry about integer overflow.
* lisp/cedet/semantic/wisent/comp.el (wisent-BITS-PER-WORD):
* lisp/gnus/message.el (message-unique-id):
* lisp/org/org-footnote.el (org-footnote-new):
Simplify.
* lisp/erc/erc-dcc.el (erc-most-positive-int-bytes)
(erc-most-positive-int-msb): Remove; no longer needed.
* lisp/net/imap.el (imap-string-to-integer): Remove; unused.
* lisp/org/org-element.el (org-element--cache-generate-key):
Document fixnum limitation.
Add commands to go to source if available, and to show and hide
Edebug's instrumentation. Make Edebug pop to backtraces instead of
displaying them, which makes Edebug consistant with the behavior of
ERT and the Lisp Debugger.
* doc/lispref/edebug.texi (Edebug Misc): Document when and how you can
jump to source code from an Edebug backtrace. Document
'edebug-backtrace-show-instrumentation' and

describe the fields.

abnormal hook.

backtrace-goto-source.

(debug): Use a debugger-buffer-state object to save and restore buffer
state. Fix bug#15749 by leaving an unused buffer in debugger-mode,
empty, instead of in fundamental-mode, and then when reusing a buffer,
not calling debugger-mode if the buffer is already in debugger-mode.
(debugger-insert-backtrace): Remove.
(debugger-setup-buffer): Use backtrace-mode.
(debugger--insert-header): New function.
(debugger-continue, debugger-return-value): Change check for flags to
use backtrace-frames.
(debugger-frame-number): Determine backtrace frame number from
backtrace-frames.
(debugger--locals-visible-p, debugger--insert-locals)
(debugger--show-locals, debugger--hide-locals)

navigation commands to backtrace-mode-map. Bind 'q' to debugger-quit
instead of top-level. Make Help Follow menu item call

(edebug--symbol-not-prefixed-p): New functions.
* lisp/emacs-lisp/lisp-mode.el

(ert--insert-backtrace-header): New function.
* tests/lisp/emacs-lisp/ert-tests.el (ert-test--which-file):
Use backtrace-frame slot accessor.
Add an Edebug matching function for cl-macrolet which keeps track of
its bindings and treats them as macros without Edebug specs when found
in the body of the expression.
* lisp/emacs-lisp/edebug.el (edebug--cl-macrolet-defs): New variable.
(edebug-list-form-args): Use it.
