* lisp/emacs-lisp/bytecomp.el (byte-compile-file): Don’t fail if
target filename doesn’t contain a directory name.
* test/lisp/emacs-lisp/bytecomp-tests.el
(bytecomp-tests--target-file-no-directory): New unit test.
See Bug#44631. While testing for a readonly output directory has
slightly different semantics, in practice they should cover cases
where Emacs is sandboxed and can only write to the destination file,
not its directory.
* lisp/emacs-lisp/bytecomp.el (byte-compile-file): Handle the case
where the output directory is not writable.
* test/lisp/emacs-lisp/bytecomp-tests.el
(bytecomp-tests--not-writable-directory)
(bytecomp-tests--dest-mountpoint): New unit tests.
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.
* lisp/emacs-lisp/comp-cstr.el (comp-cstr-union-1-no-mem):
Generalize disjoint pos types vs neg values conditions.
(comp-cstr-union-1-no-mem): Do not propagate ranges when we are
already returning integer as generic type.
* test/lisp/emacs-lisp/comp-cstr-tests.el
(comp-cstr-typespec-tests-alist): Add corresponding tests.
* lisp/emacs-lisp/comp-cstr.el (comp-range-negation): New
function.
(comp-cstr-union-homogeneous-no-range): Rename from
`comp-cstr-union-no-range'.
(comp-cstr-union-homogeneous): Rename from `comp-cstr-union'.
(comp-cstr-union-1): New function.
(comp-cstr-union-no-range, comp-cstr-union): Rewrite in function
of `comp-cstr-union-1'.
* test/lisp/emacs-lisp/comp-cstr-tests.el
(comp-cstr-typespec-tests-alist): Add a bunch of tests.
As the constraint logic of the compiler is not trivial and largely
independent from the rest of the code move it into comp-cstr.el to
ease separation and maintainability.
This commit improve the conversion type
specifier -> constraint for generality.
Lastly this should help with bootstrap time as comp.el compilation
unit is slimmed down.
* lisp/emacs-lisp/comp-cstr.el: New file.
(comp--typeof-types, comp--all-builtin-types): Move from comp.el.
(comp-cstr, comp-cstr-f): Same + rename.
(comp-cstr-ctxt): New struct.
(comp-supertypes, comp-common-supertype-2)
(comp-common-supertype, comp-subtype-p, comp-union-typesets)
(comp-range-1+, comp-range-1-, comp-range-<, comp-range-union)
(comp-range-intersection): Move from comp.el.
(comp-cstr-union-no-range, comp-cstr-union): Move from comp.el and
rename.
(comp-cstr-union-make): New function.
(comp-type-spec-to-cstr, comp-cstr-to-type-spec): Move from
comp.el, rename it and rework it.
* lisp/emacs-lisp/comp.el (comp-known-func-cstr-h): Rework.
(comp-ctxt): Remove two fields and include `comp-cstr-ctxt'.
(comp-mvar, comp-fwprop-call): Update for `comp-cstr' being
renamed.
(comp-fwprop-insn): Use `comp-cstr-union-no-range' or
`comp-cstr-union'.
(comp-ret-type-spec): Use `comp-cstr-union' and rework.
* test/lisp/emacs-lisp/comp-cstr-tests.el: New file.
(comp-cstr-test-ts, comp-cstr-typespec-test): New functions.
(comp-cstr-typespec-tests-alist): New defconst to generate tests
on.
(comp-cstr-generate-tests): New macro.
* test/src/comp-tests.el (comp-tests-type-spec-tests): Update.
(ret-type-spec): Initialize constraint context.
* test/lisp/emacs-lisp/bytecomp-tests.el
(bytecomp--with-warning-test): New macro.
(bytecomp-warn-wrong-args, bytecomp-warn-wrong-args-subr):
Use above new macro.
(bytecomp-warn-variable-lacks-prefix): New 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.
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.
* 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.
* 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.
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.
* lisp/emacs-lisp/unsafep.el:
Add comment explaining the policy for which forms can be considered
'safe' in the sense of unsafep. Remove ones that didn't make the cut:
play-sound-file (large attack surface)
catch, throw (alter program flow, inject data)
replace-regexp-in-string (execute arbitary code)
error, signal (deceptive messages)
* test/lisp/emacs-lisp/unsafep-tests.el (unsafep-tests--unsafe):
Add test cases.
* etc/NEWS: Announce the change.
* lisp/emacs-lisp/text-property-search.el
(text-property-search-forward, text-property-search-backward): Doc fix
to clarify placement of point after search.

:predicate keyword (bug#44232).

Allow a new :predicate keyword.
(easy-mmode--globalized-predicate-p): New function.
