* src/timefns.c (frac_to_double): Pass FLT_RADIX to mpz_sizeinbase
instead of doing the radix calculation ourselves, not always
correctly. Fix off-by-one error in scale, which caused
double-rounding.
(decode_time_components): Use frac_to_double (via decode_ticks_hz)
to fix double-rounding error that can occur even though
intermediate results are long double.
* test/src/timefns-tests.el (float-time-precision):
Test the above fixes.
* test/src/timefns-tests.el:
(format-time-string-padding-minimal-deletes-unneeded-zeros)
(format-time-string-padding-minimal-retains-needed-zeros)
(format-time-string-padding-spaces)
(format-time-string-padding-zeros-adds-on-insignificant-side):
Don't assume local time can represent 2000-02-15 00:00:00,
as there might be a DST jump over midnight.
Work even when timestamps are of (TICKS . HZ) form.
Simplify by avoiding need to call time-add.
Omitting the extra brackets is a common mistake; see discussion at
https://lists.gnu.org/archive/html/emacs-devel/2020-02/msg00215.html
* src/regex-emacs.c (reg_errcode_t, re_error_msgid): Add REG_ECLASSBR.
(regex_compile): Check for the mistake.
* test/src/regex-emacs-tests.el (regexp-invalid): Test.
* etc/NEWS: Announce.
* src/alloc.c (resize_string_data): The string must be multibyte.
When not bothering to reallocate, do bother to change the byte count.
* test/src/alloc-tests.el (aset-nbytes-change) New test.
Problem reported by Pip Cet (Bug#38912#14).
* doc/lispref/objects.texi (Equality Predicates):
Document better when ‘equal’ looks inside objects.
* doc/lispref/windows.texi (Window Configurations):
Don’t say that ‘equal’ looks inside window configurations.
* etc/NEWS: Mention the change.
* src/fns.c (internal_equal):
Do not look inside window configurations.
(sxhash_obj): Hash markers, byte-code function objects,
char-tables, and font objects consistently with Fequal.
* src/window.c (compare_window_configurations):
Now static. Remove last argument. Caller changed.
* test/lisp/ffap-tests.el (ffap-other-window--bug-25352):
Use compare-window-configurations, not ‘equal’.
* test/src/fns-tests.el (test-sxhash-equal): New test.
This is especially useful in cases where modules only use a single
entry point and use the data to dispatch to the actual function. Such
a design is common for languages such as Go and C++.
* src/emacs-module.c (module_function_data): New function.
* src/print.c (print_vectorlike): Use it to print module function data
if not NULL.
(print_object): Adapt size of buffer.
* test/data/emacs-module/mod-test.c (emacs_module_init): Pass some
non-NULL data to ‘mod-test-sum’.
(Fmod_test_sum): Check that correct data is passed through.
* test/src/emacs-module-tests.el (mod-test-sum-test)
(module-function-object): Adapt unit tests.
* test/src/emacs-module-tests.el (module/function-finalizer): Create
100 leaked functions to increase the probability that at least one
gets garbage-collected.
* src/module-env-28.h: Add new module environment functions to
module environment for Emacs 28.
* src/emacs-module.h.in: Document that 'emacs_finalizer' also works
for function finalizers.
* src/emacs-module.c (CHECK_MODULE_FUNCTION): New function.
(struct Lisp_Module_Function): Add finalizer data member.
(module_make_function): Initialize finalizer.
(module_get_function_finalizer)
(module_set_function_finalizer): New module environment functions.
(module_finalize_function): New function.
(initialize_environment): Initialize new environment functions.
* src/alloc.c (cleanup_vector): Call potential module function
finalizer during garbage collection.
* test/data/emacs-module/mod-test.c (signal_error): New helper
function.
(memory_full): Use it.
(finalizer): New example function finalizer.
(Fmod_test_make_function_with_finalizer)
(Fmod_test_function_finalizer_calls): New test module functions.
(emacs_module_init): Define them.
* test/src/emacs-module-tests.el (module/function-finalizer): New unit
test.
* doc/lispref/internals.texi (Module Functions): Document new
functionality.
(Module Misc): Move description of 'emacs_finalizer' type to 'Module
Functions' node, and add a reference to it.
* etc/NEWS: Mention new functionality.
