* lisp/emacs-lisp/cl-print.el (cl-print--depth): New variable.
(cl-print-object) <cons>: Print ellipsis if printing depth greater
than 'print-level' or length of list greater than 'print-length'.
(cl-print-object) <vector>: Truncate printing with ellipsis if
vector is longer than 'print-length'.
(cl-print-object) <cl-structure-object>: Truncate printing with
ellipsis if structure has more slots than 'print-length'.
(cl-print-object) <:around>: Bind 'cl-print--depth'.
* test/lisp/emacs-lisp/cl-print-tests.el
(cl-print-tests-3, cl-print-tests-4): New tests.
Suggested by Drew Adams (Bug#31311).
* lisp/emacs-lisp/pcase.el (pcase): Use EXPVAL in
docstring to stand for the result of evaluating EXP.
(pcase-defmacro): Add (fn ...) form in docstring
that includes [DOC], and the EXPVAL convention.
* lisp/emacs-lisp/pcase.el (pcase--make-docstring):
Split extensions display into two phases, collection
and display, separated by a reordering step that
ensures backquote is the first.

* lisp/emacs-lisp/cl-print.el (cl-print-object) <cons>: Push each
element of list being printed onto cl-print--currently-printing.
* test/lisp/emacs-lisp/cl-print-tests.el (cl-print-circle-2): New
test.
* lisp/emacs-lisp/eieio-base.el (eieio-persistent-validate/fix-slot-value):
Make handling of hash tables and vectors recursive. This is
necessary because the write process, in `eieio-override-prin1' is
also recursive. With any luck, this will be the last fix of its
kind. If that's true, cherry-pick to Emacs 26.2 later on.
* lisp/emacs-lisp/crm.el (completing-read-multiple):
Consider head of DEF argument when specified as a list,
as per completing-read-default. (bug#30072)
* doc/lispref/control.texi (Pattern matching case statement):
* lisp/emacs-lisp/pcase.el (pcase): State that pcase returns nil if no
patterns match.
(pcase-exhaustive): State that an error is signaled if no patterns
match.
This suppresses some byte-code optimizations that were invalid in
the presence of integer overflows, because they meant that .elc
files assumed the runtime behavior of the compiling platform, as
opposed to the runtime platform. Problem reported by Pip Cet in:
https://lists.gnu.org/r/emacs-devel/2018-03/msg00753.html
* lisp/emacs-lisp/byte-opt.el (byte-opt--portable-max)
(byte-opt--portable-min): New constants.
(byte-opt--portable-numberp, byte-opt--arith-reduce)
(byte-optimize-1+, byte-optimize-1-): New functions.
(byte-optimize-plus, byte-optimize-minus, byte-optimize-multiply)
(byte-optimize-divide): Avoid invalid optimizations.
(1+, 1-): Use new optimizers.
(byte-optimize-or, byte-optimize-cond): Simplify by using
remq instead of delq and copy-sequence.
For the following release it is planned to make `if-let*' and
`when-let*' aliases for `if-let' and `when-let'. For now we revert
declaring `if-let' and `when-let' obsolete and tweak the docstrings.
* lisp/emacs-lisp/subr-x.el (if-let*, when-let*): Make docstrings
refer to those of `if-let' and `when-let'.
(if-let, when-let): De-obsolete. Rewrite documentation.
(package--quickstart-pkgs): New var.
(package-activate-1): Obey and fill it.
(package-activate-all): New function.
(package-initialize): Call it.
Set package-initialized before activating the packages.
(package-installed-p): Make it work before package.el is initialized in
the case where min-version is not specified.
(package-install, package-delete): Refresh the quickstart if applicable.
(package-quickstart, package-quickstart-file): New vars.
(package--quickstart-maybe-refresh, package-quickstart-refresh):
New functions.
* lisp/startup.el (command-line): Use package-activate-all rather than
package-initialize.
* doc/lispref/package.texi (Packaging Basics):
* doc/emacs/package.texi (Package Installation):
* doc/lispref/os.texi (Startup Summary): Refer to package-activate-all.
* lisp/emacs-lisp/byte-opt.el (byte-optimize-memq): Call
byte-optimize-and only for memq forms that can be optimized, use
byte-optimize-predicate to optimize the final form.
When optimizing arithmetic operations, avoid optimizations that
are valid for mathematical numbers but invalid for floating-point.
For example, do not optimize (+ 1 v 0.5) to (+ v 1.5), as they may
not be the same due to rounding errors. In general,
floating-point numbers cannot be constant-folded, since that would
make .elc files platform-dependent.
* lisp/emacs-lisp/byte-opt.el (byte-optimize-associative-math):
Do not optimize floats.
(byte-optimize-nonassociative-math, byte-optimize-approx-equal)
(byte-optimize-delay-constants-math, byte-compile-butlast)
(byte-optimize-logmumble):
Remove; no longer used.
(byte-optimize-minus): Do not optimize (- 0 x) to (- x).
(byte-optimize-multiply): Do not optimize (* -1 x) to (- x).
(byte-optimize-divide): Do not optimize (/ x -1) to (- x).
(logand, logior, logxor): Optimize with byte-optimize-predicate
instead of with byte-optimize-logmumble.
* test/lisp/emacs-lisp/bytecomp-tests.el:
(byte-opt-testsuite-arith-data): Add a couple of test cases.
This fixes a bug where a byte-compiler running on 64-bit Emacs
optimized (lsh -1 -1) to #x1fffffffffffffff, an optimization
that is incorrect for .elc files intended for either 32- or
64-bit Emacs. While I was in the neighborhood, I noticed other
glitches in the lists of pure and side-effect-free functions, and
fixed the errors that I found.
* lisp/emacs-lisp/byte-opt.el (side-effect-free-fns):
Move some functions here from side-effect-and-error-free-fns,
since they can now signal errors. The affected functions are
current-time-string, current-time-zone,
line-beginning-position, line-end-position. Rename langinfo
to locale-info. Add logcount. Remove string-to-int.
(side-effect-and-error-free-fns): Remove minibuffer-window, a
function that can signal errors, and that is already in
side-effect-free-fns.
(pure-fns): Remove ash, lsh, and logb, since they are
platform-dependent and .elc files should be
platform-independent. Add %, logand, logcount. Sort.
Clarify what is meant by “pure”.
* lisp/emacs-lisp/eieio-base.el (eieio-persistent-validate/fix-slot-value):
`object-write' may quote lists inside hash tables and vectors, so
unquote those lists here.
This patch allows the eieio-persistent write/restore process to
perform a clean round trip. It only handles a very specific and
limited range of object structures, but at least the write and read
procedures match.
* lisp/emacs-lisp/eieio-base.el (eieio-persistent-validate/fix-slot-value):
The function `eieio-persistent-slot-type-is-class-p' could return
either a single class, or a list of classes.
