Implement the RFC4648 variant of base64 encoding used by URLs.
* doc/lispref/text.texi (base64url-encode-region,
base64url-encode-string): Document new functions.
(base64-decode-region, base64-decode-string): Document new optional
parameter 'base64url' used to use url variant when decoding data.
* src/fns.c (base64url-encode-region, base64url-encode-region): New
functions to manage url variant.
(base64-decode-region, base64-decode-string): Add optional
parameter to indicate use of url-variant.
(base64_encode_region_1, base64_encode_string_1): Internal functions
with extracted code from 'base64_encode_region' and
'base64_encode_string' and optional parameters to manage padding and
url variant.
(base64-encode-region, base64-encode-string) : Use
base64_encode_region_1 and base64_encode_string_1.
(base64-encode-1): Add parameters to manage padding and url variant.
(base64-decode-1): Add parameter to manage url variant.
* test/src/fns-tests.el (fns-tests--with-region): New helper macro to
test region variant of base64 encode / decode functions.
(fns-tests--string-repeat): Helper function used in base64 tests.
(fns-tests-base64-encode-region, fns-tests-base64-encode-string):
Tests for standard base64 function.
(fns-test-base64url-encode-region,
fns-test-base64url-encode-string): Tests for url variant.
(fns-tests-base64-decode-string): Tests for decoding part.
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.
* src/timefns.c (Fencode_time): Ignore DST flag when the zone is
numeric or is a cons, as the doc string says it’s ignored in that
case, and not ignoring it causes encode-time to not invert
decode-time on some platforms (Bug#35502).
* test/src/timefns-tests.el (encode-time-dst-numeric-zone):
New test.
* doc/lispref/internals.texi (Module Values): Clarify that the
truncation is towards negative infinity.
* test/data/emacs-module/mod-test.c (Fmod_test_nanoseconds): Add test
function.
(emacs_module_init): Define it.
* test/src/emacs-module-tests.el (mod-test-nanoseconds): New unit test.
make_time is documented to return a (TICKS . HZ) pair, so we can’t use
make_lisp_time. Introduce a new conversion function instead.
* src/emacs-module.c (module_make_time): Use timespec_to_lisp to
correct return type.
* src/timefns.c (timespec_to_lisp): New function.
(make_lisp_time): Use it.
* test/src/emacs-module-tests.el (mod-test-add-nanosecond/valid):
Check return type.
* src/module-env-27.h: Add new module functions to convert big
integers.
* src/emacs-module.h.in (emacs_mpz): Define if GMP is available.
* src/emacs-module.c (module_extract_big_integer)
(module_make_big_integer): New functions.
(initialize_environment): Use them.
* test/data/emacs-module/mod-test.c (Fmod_test_double): New test
function.
(emacs_module_init): Define it.
* test/src/emacs-module-tests.el (mod-test-double): New unit test.
* doc/lispref/internals.texi (Module Values): Document new functions.
Time values are a fundamental data type, and such conversions are hard
to implement within modules because of the various forms of time
values in Emacs Lisp. Adding dedicated conversion functions can
significantly simplify module code dealing with times.
This approach uses nanosecond precision. While Emacs in theory has
support for higher-precision time values, in practice most languages
and standards, such as POSIX, C, Java, and Go, have settled on
nanosecond-precision integers to represent time.
* src/emacs-module.h.in: Add header for struct timespec.
* src/module-env-27.h: Add module functions for time conversion.
* src/emacs-module.c (module_extract_time, module_make_time): New
functions.
(initialize_environment): Use them.
* test/data/emacs-module/mod-test.c (Fmod_test_add_nanosecond): New
test function.

(mod-test-add-nanosecond/nil, mod-test-add-nanosecond/invalid): New
unit tests.
* doc/lispref/internals.texi (Module Values): Document time
conversion functions.
* test/src/json-tests.el (json-parse-string/null): Make JSON object
syntactically valid. This test is supposed to check whether an
escaped null character causes an error, but without quoting the string
it would be syntactically invalid in any case.
See Bug#31676.
* lisp/emacs-lisp/byte-run.el
(byte-run--unescaped-character-literals-warning): New defun.
* src/lread.c (load_warn_unescaped_character_literals): Use new defun.
(syms_of_lread): Define symbol for new defun.
* lisp/emacs-lisp/bytecomp.el (byte-compile-from-buffer): Use new
defun.
* test/src/lread-tests.el (lread-tests--unescaped-char-literals):
test/lisp/emacs-lisp/bytecomp-tests.el
(bytecomp-tests--unescaped-char-literals): Adapt unit tests.
This has never worked and caused issues such as Bug#30460.
* src/process.c (Fmake_process): Don't accept :stop key any more.
(syms_of_process): Define needed symbol 'null'.
* test/src/process-tests.el (make-process/stop): New unit test.
* doc/lispref/processes.texi (Asynchronous Processes): Remove :stop
key from manual.
Since child_setup() is called between block_input()...unblock_input(),
when an error is signaled the Lisp debugger is prevented from
starting. Therefore, let the callers signal the error instead (which
they already do for non-w32 platforms, just the error message needs an
update).
* src/callproc.c (child_setup) [WINDOWSNT]: Don't call
report_file_error here.
(call_process) [WINDOWNT]:
* src/process.c (create_process) [WINDOWSNT]: Call report_file_errno
here instead, after the unblock_input() call, same as for !WINDOWSNT.
* src/lisp.h (CHILD_SETUP_ERROR_DESC): New preprocessor define. Flip
the containing ifndef DOS_NT branches so that it's ifdef DOS_NT.
* src/eval.c (when_entered_debugger): Remove.
(syms_of_eval) <internal-when-entered-debugger>: Define it as a Lisp
integer variable instead.
(maybe_call_debugger): Update comment.
* test/src/process-tests.el (make-process-w32-debug-spawn-error):
* test/src/callproc-tests.el (call-process-w32-debug-spawn-error): New
tests.
* src/json.c (enum json_array_type): New type.
(struct json_configuration): New field array_type.
(json_parse_args): Rename the last argument. Handle the
:array-type keyword argument (bug#32793).
(Fjson_parse_string): Update the docstring accordingly.
(json_to_lisp): Handle the case of :array-type being `list'. Add
a call to 'rarely_quit' inside the loop.
(syms_of_json): Define new symbols.
(Fjson_serialize, Fjson_insert, Fjson_parse_string)
(Fjson_parse_buffer): Update the config struct initializers.
This follows the move of proper-list-p from lisp/subr.el to
src/fns.c in 2018-07-24T15:58:46-07:00!eggert@cs.ucla.edu.
* test/lisp/subr-tests.el (subr-tests--proper-list-p): Move from
here...
* test/src/fns-tests.el (test-proper-list-p): ...to here.
* etc/NEWS:
* src/editfns.c (Fformat, binary_as_unsigned):
Update now that we always have bignums.
(syms_of_editfns) [!defined lisp_h_FIXNUMP]: Remove now-obsolete
code, since lisp_h_FIXNUMP is always defined now.
* test/src/editfns-tests.el (read-large-integer): Simplify,
now that we can assume binary-as-unsigned defaults to nil.
pending_signals is often set if no quit is pending. This results in
bugs in module code if the module returns but no quit is actually
pending.
As a better alternative, add a new process_input environment function
for Emacs 27. That function processes signals (like maybe_quit).
* configure.ac: Add module snippet for Emacs 27.
* src/module-env-27.h: New file.
* src/emacs-module.h.in: Add process_input function to environment
interface.
* src/emacs-module.c (module_should_quit): Use QUITP macro to check
whether the caller should quit.
(module_process_input): New function.
(initialize_environment): Use it.
* src/eval.c: Remove obsolete comment.
* test/data/emacs-module/mod-test.c (signal_wrong_type_argument)
(signal_errno): New helper functions.
(Fmod_test_sleep_until): New test module function.
* test/src/emacs-module-tests.el (mod-test-sleep-until): New unit
test.
* doc/lispref/internals.texi (Module Misc): Document process_input.
* doc/lispref/searching.texi (Character Classes):
* lisp/emacs-lisp/rx.el (rx):
Document that [:cntrl:] excludes DEL.
* test/src/regex-emacs-tests.el (regex-tests-PTESTS-whitelist):
Swap misplaced comments and fix wrong code for DEL.
* src/cmds.c (Fforward_line): Support bignum arg.
(scan_newline): Return void since no caller was using the
return value.
* src/search.c (find_newline, scan_newline_from_point)
(find_newline1): Return the number of newlines counted, not
the count shortage, so that the return value always fits in
ptrdiff_t even if the original count was a bignum. All
callers changed.
* test/src/cmds-tests.el (forward-line-with-bignum): New test.
Also, clean up the code a bit.
Actually I discovered the bug while cleaning up the code.
* src/editfns.c (Fsubst_char_in_region)
(Ftranslate_region_internal): Use bool for booleans.
(Ftranslate_region_internal): Fix off-by-1 bug when a
translation table translates the maximum char. Assume C99
decl-after-statement, similar minor cleanups.
* test/src/editfns-tests.el (test-translate-region-internal):
New test.

UPDATE_COPYRIGHT_MAX_LINE_LENGTH=79 admin/update-copyright'
followed by 'admin/merge-gnulib'.
* src/process.c (Fmake_process): Add new keyword argument
':file-handler'.
(syms_of_process) <make-process, :file-handler>: Define new symbols.

(files-tests-file-name-non-special-make-process): New unit test.
* doc/lispref/files.texi (Magic File Names): Document that
'make-process' can invoke file name handlers.
* doc/lispref/processes.texi (Asynchronous Processes): Document
':file-handlers' argument to 'make-process'.
* etc/NEWS (Lisp Changes in Emacs 27.1): Mention new
:file-handler argument for 'make-process'.
* src/keyboard.c (read_char): Events put into `unread-command-events'
with the form (t . EVENT) should always have the t stripped when read
out.
* test/src/keyboard-tests.el: New tests for `unread-command-events'.
(cherry picked from commit 1f3f4b1296)
* src/data.c (emacs_mpz_mul_2exp): 2nd arg is now a
nonnegative EMACS_INT not mp_bitcnt_t, to simplify checking.
(Fash): Support COUNT values that are bignums or that
exceed mp_bitcnt_t range.
* test/src/data-tests.el (data-tests-ash-lsh): Test this.

$HOME to begin with "X:/".
* test/src/fileio-tests.el (fileio-tests--relative-HOME): Add
testing of drive-relative value of $HOME on MS-Windows and
MS-DOS.
POSIX says sh ~/foo should act like $HOME/foo even if $HOME is
relative, so be consistent with that (Bug#33255).
* admin/merge-gnulib (GNULIB_MODULES): Add dosname.
* src/buffer.c (init_buffer): Use emacs_wd to get
initial working directory with slash appended if needed.
(default-directory): Say it must be absolute.

(init_cmdargs): Dir arg is now char const *.
(main): Set emacs_wd.
* src/emacs.c (main) [NS_IMPL_COCOA]:
* src/fileio.c (Fexpand_file_name):
Use get_homedir instead of egetenv ("HOME").
* src/fileio.c: Include dosname.h, for IS_ABSOLUTE_FILE_NAME.
(splice_dir_file, get_homedir): New functions.
* src/xrdb.c (gethomedir): Remove. All callers changed
to use get_homedir and splice_dir_file.

* src/editfns.c (Fgroup_name): Fix the doc string. Move
closer to the "group" functions.
