* Edebug: Overload `edebug-form-spec` even lessStefan Monnier2021-02-122-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The `edebug-form-spec` symbol property was used both to map forms's head symbol to the corresponding spec, and to map spec element names to their expansion. This lead to name conflicts which break instrumentation of examples such as (cl-flet ((gate (x) x)) (gate 4)) because of the Edebug spec element `gate`. So introduce a new symbol property `edebug-elem-spec`. * lisp/subr.el (def-edebug-elem-spec): New function. * lisp/emacs-lisp/edebug.el (edebug--get-elem-spec): New function. (edebug-match-symbol): Use it. (Core Edebug elems): Put them on `edebug-elem-spec` instead of `edebug-form-spec`. (ELisp special forms): Set their `edebug-form-spec` via dolist. (Other non-core Edebug elems): Use `def-edebug-elem-spec`. (edebug-\`): Use `declare`. * lisp/emacs-lisp/pcase.el (pcase-PAT, pcase-FUN, pcase-QPAT): * lisp/skeleton.el (skeleton-edebug-spec): * lisp/emacs-lisp/cl-macs.el: Use `def-edebug-elem-spec`. * test/lisp/emacs-lisp/edebug-tests.el (edebug-tests--conflicting-internal-names): New test. * test/lisp/emacs-lisp/edebug-resources/edebug-test-code.el (edebug-test-code-cl-flet1): New test case. * doc/lispref/edebug.texi (Specification List): Add `def-edebug-elem-spec`. (Specification Examples): Use it. * doc/lispref/loading.texi (Hooks for Loading): Avoid the use of `def-edebug-spec` in example (better use `debug` declaration).

* Fix local defvar scoping error (bug#46387)Mattias Engdegård2021-02-101-0/+31
| | | | | | | | | | | | This bug was introduced by the lexical variable constant propagation mechanism. It was discovered by Michael Heerdegen. * lisp/emacs-lisp/byte-opt.el (byte-optimize-let-form) (byte-optimize-body): Let the effects of a local defvar declaration be scoped by let and let*, not any arbitrary Lisp expression body (such as progn). * test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--get-vars) (bytecomp-local-defvar): New test.

* Constprop of lexical variablesMattias Engdegård2021-02-061-1/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | Lexical variables bound to a constant value (symbol, number or string) are substituted at their point of use and the variable then eliminated if possible. Example: (let ((x (+ 2 3))) (f x)) => (f 5) This reduces code size, eliminates stack operations, and enables further optimisations. The implementation is conservative, and is strongly curtailed by the presence of variable mutation, conditions and loops. * lisp/emacs-lisp/byte-opt.el (byte-optimize-enable-variable-constprop) (byte-optimize-warn-eliminated-variable): New constants. (byte-optimize--lexvars, byte-optimize--vars-outside-condition) (byte-optimize--vars-outside-loop, byte-optimize--dynamic-vars): New dynamic variables. (byte-optimize--substitutable-p, byte-optimize-let-form): New functions. (byte-optimize-form-code-walker): Adapt clauses for variable constprop, and add clauses for 'setq' and 'defvar'. * test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-test-var) (bytecomp-test-get-var, bytecomp-test-identity) (byte-opt-testsuite-arith-data): Add test cases.

| | | | | | | | | | | | | | | | | | For discussion, see the following thread: https://lists.gnu.org/r/emacs-devel/2021-01/msg01111.html * test/lisp/autorevert-tests.el (auto-revert-test07-auto-revert-several-buffers): * test/lisp/emacs-lisp/seq-tests.el (test-seq-do-indexed) (test-seq-random-elt-take-all): Fix errors from using add-to-list on lexical variables. * test/lisp/emacs-lisp/cl-lib-tests.el (cl-lib-defstruct-record): Expect test to succeed when byte-compiled following change of 2021-01-23 'Fix missing file&line info in "Unknown defun property" warnings'. (cl-lib-tests--dummy-function): Remove; no longer needed. (old-struct): Silence byte-compiler warning about unused lexical variable.
* Fix spurious "Lexical argument shadows the dynamic variable" due to inliningStefan Monnier2021-01-213-0/+27
| | | | | | | | | | | | | | | | | | | Before this patch doing: rm lisp/calendar/calendar.elc make lisp/calendar/cal-hebrew.elc would spew out lots of spurious such warnings about a `date` argument, pointing to code which has no `date` argument in sight. This was because that code had calls to inlinable functions (taking a `date` argument) defined in `calendar.el`, and while `date` is a normal lexical var at the site of those functions' definitions, it was declared as dynbound at the call site. * lisp/emacs-lisp/byte-opt.el (byte-compile-inline-expand): Don't impose our local context onto the inlined function. * test/lisp/emacs-lisp/bytecomp-tests.el: Add matching test.
* * lisp/emacs-lisp/pcase.el: Add support for `not` to `pred`Stefan Monnier2021-01-161-0/+4
| | | | | | | | | | | | | (pcase--split-pred, pcase--funcall): Adjust for `not`. (pcase--get-macroexpander): New function. (pcase--edebug-match-macro, pcase--make-docstring) (pcase--macroexpand): Use it. * lisp/emacs-lisp/radix-tree.el (radix-tree-leaf): Use it! * doc/lispref/control.texi (The @code{pcase} macro): Document it. * lisp/emacs-lisp/ert.el (ert--explain-equal-rec): Remove redundant test.
* Fix two testsEli Zaretskii2021-01-161-2/+2
| | | | | | | | | | * test/lisp/progmodes/elisp-mode-tests.el (xref-elisp-test-run): Make sure file names can be compared as strings, by running them through 'file-truename'.

* * lisp/emacs-lisp/cl-macs.el: Optimize self-calls in tail positionStefan Monnier2021-01-081-1/+16
| | | | | | | | | | | | | | | | | | | Implement a limited form of tail-call optimization for the special case of recursive functions defined with `cl-labels`. Only self-recursion is optimized, no attempt is made to handle more complex cases such a mutual recursion. The main benefit is to reduce the use of the stack, tho in my limited tests, this can also improve performance (about half of the way to a hand-written `while` loop). (cl--self-tco): New function. (cl-labels): Use it. * lisp/subr.el (letrec): Optimize single-binding corner case. * test/lisp/emacs-lisp/cl-macs-tests.el (cl-macs--labels): Add tests to check that TCO is working.

* Fix bug in how ERT invokes its debugger.Philipp Stephani2020-12-071-0/+10
| | | | | | | | | | | | | | | The debugger needs to receive a list of the error symbol and data; cf. the documentation of the `debugger' variable. This bug manifested itself in ERT forms such as (should (integerp (ert-fail "Boo"))), which resulted in an incorrect condition object. Note that forms such as (should (ert-fail "Boo")) weren't affected because they wouldn't use the `ert--should-signal-hook'. * test/emacs-lisp/ert.el (ert--should-signal-hook): Call debugger with the right arguments. * test/lisp/emacs-lisp/ert-tests.el (ert-test-fail-inside-should): Add unit test.

| | | | | | * test/lisp/emacs-lisp/rx-tests.el (rx-compat): Use with-no-warnings instead of with-suppressed-warnings which complains when running the test interactively.
* Fix pcase rx form snag with '?' and '??' (bug#44532)Mattias Engdegård2020-11-091-1/+5
| | | | | | | | This is a regression from Emacs 26. Reported by Phillip Stephani. * lisp/emacs-lisp/rx.el (rx--pcase-transform): Process ? and ?? correctly. * test/lisp/emacs-lisp/rx-tests.el (rx-pcase): Add test case.
* ; Silence byte-compiler warnings in testsStefan Kangas2020-11-051-12/+13
| | | | | | * test/lisp/emacs-lisp/easy-mmode-tests.el (easy-mmode--minor-mode): * test/lisp/progmodes/cperl-mode-tests.el (cperl-bug30393): Silence byte-compiler.
* Partially revert previous define-minor-mode changeLars Ingebrigtsen2020-11-021-8/+2
| | | | | | | * lisp/emacs-lisp/easy-mmode.el (easy-mmode--arg-docstring): Only document the values we want to support, not the ones we actually support. (define-minor-mode): Partially revert to previous behaviour.
* Make minor mode ARG work as documentedLars Ingebrigtsen2020-11-011-0/+21
| | | | | | | | * lisp/emacs-lisp/easy-mmode.el (easy-mmode--arg-docstring): Clarify when minor modes are switched on/off when called from lisp (bug#44341). (define-minor-mode): Make calls from Lisp switch the mode on/off as documented.
* 'assoc' is not side-effect-free; constprop its pure subsetMattias Engdegård2020-10-311-1/+6
| | | | | | | | | | | Since a supplied test function can do anything, assoc is not side-effect-free (bug#44018). However, with only two arguments it is pure and should be optimised accordingly. * lisp/emacs-lisp/byte-opt.el (side-effect-free-fns): Remove 'assoc'. (byte-optimize-assoc): Constant-propagate through 2-arg assoc calls. * test/lisp/emacs-lisp/bytecomp-tests.el (byte-opt-testsuite-arith-data): Add test cases.
