This incorporates:
2019-12-06 nstrftime: better width support for %N, %z
2019-12-03 Avoid hassles caused by [[noreturn]] in C++
2019-12-02 Fix mistakes in --enable-threads=isoc fixes from 2019-12-01
* admin/merge-gnulib (AVOIDED_MODULES): Avoid pthread-h.
* lib/_Noreturn.h, lib/nstrftime.c, m4/gnulib-common.m4:
* m4/timer_time.m4:
Copy from Gnulib.
* lib/gnulib.mk.in: Regenerate.
etags had undefined behavior if input files, lines, tags, etc.,
had more than INT_MAX bytes. Clean up the usage of integer types
to fix the overflow errors I found.
* admin/merge-gnulib (GNULIB_MODULES): Add mempcpy.
* lib-src/etags.c: Include inttypes.h, intprops.h.
(memcpyz): New function. Use it to simplify several occurrences
of memcpy followed by storing a trailing '\0'.
(xnew): Use xnmalloc, to catch overflow on integer multiplication.
(xrnew): Change last arg to multiplier. The type is not needed.
All callers changed.
(node, lineno, charno, linecharno, invalidcharno, make_tag):
(pfnote, add_node, number_len, C_symtype, lbz, Makefile_targets)
(readline):
Use intmax_t for line numbers and character positions, instead of
int or long.
(linebuffer, make_tag, pfnote, total_size_of_entries, put_entry)
(in_word_set, C_symtype, token, cstack, pushclass_above):
(popclass_above, write_classname, consider_token, C_entries)
(Ruby_functions, Makefile_targets, Lua_functions, TeX_commands)
(TeX_decode_env, erlang_func, erlang_attribute, erlang_atom)
(substitute, regex_tag_multiline, nocase_tail, readline_interval)
(readline, savenstr, concat, etags_getcwd, relative_filename)
(linebuffer_setlen):
Use ptrdiff_t for object sizes, instead of int or long or unsigned
or size_t.
(write_classname, C_entries):
Avoid sprintf, as the result could exceed INT_MAX bytes
and then behavior goes haywire.
(main): Use int, instead of unsigned, for argv counts.
(get_language_from_filename): Use bool for boolean.
(Ruby_functions): Prefer strcpy to memcpy when copying "=".
(linebuffer_setlen): Use ‘if’ instead of ‘while’.
(memory_full, xnmalloc, xnrealloc): New functions.
(xmalloc): Use memory_full, and take a ptrdiff_t instead of a size_t.
(xrealloc): Remove; no longer needed.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* lib/mempcpy.c, m4/mempcpy.m4: New files, copied from Gnulib.
This mostly changes http: to https: in URLs. It also updates
some URLs that have moved, removes some URLs that no longer
work, recommends against using procmail (procmail.org no
longer works), and removes some mentions of the
no-longer-existing Gmane, LPF and VTW.
It doesn't update all URLs, just the ones I had time for.
* GNUmakefile (help):
* admin/admin.el (manual-doctype-string):
* admin/charsets/Makefile.in (${charsetdir}/ALTERNATIVNYJ.map):
* admin/charsets/mapconv:
* lisp/net/soap-client.el (soap-create-envelope):
* lisp/org/org.el (org-doi-server-url):
* lisp/textmodes/bibtex.el (bibtex-generate-url-list):
Prefer https: to http: un URLs.
Problem reported by Sven Joachim (Bug#36907).
* admin/make-emacs: Simplify, now that clean does versionclean.
* src/Makefile.in ($(etc)/DOC, versionclean, extraclean):
Don’t ignore rm -f failures.
(versionclean): Also remove emacs-*.*.*[0-9].pdmp and ../etc/DOC*.
(clean): Depend on versionclean and simplify.
* admin/merge-gnulib (GNULIB_MODULES): Add double-slash-root.
Emacs was already using this Gnulib module indirectly, so this
is merely noting that there is now a direct dependency.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* src/fileio.c (search_embedded_absfilename):
Use DOUBLE_SLASH_IS_DISTINCT_ROOT instead of (WINDOWSNT || CYGWIN).
Simplify.
PATH_MAX is standardized, MAXPATHLEN is not.
Also, the Gnulib pathmax module fixes some rare bugs with PATH_MAX.
So prefer PATH_MAX to MAXPATHLEN unless we know the latter is
also correct (for some platform-specific code).
* admin/merge-gnulib (GNULIB_MODULES): Add pathmax.
This module was already present, as a dependency of canonicalize-lgpl,
but now Emacs is using it directly. Sort.
* lib-src/emacsclient.c: Include stdint.h, pathmax.h.
(get_current_dir_name): Sync to current src/sysdep.c.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* src/sysdep.c: Include pathmax.h.
(get_current_dir_name_or_unreachable):
Use PATH_MAX instead of MAXPATHLEN.
* admin/unidata/Makefile.in (extraclean): Don't delete macuvs.h,
because it's a checked-in file, and make targets altering
checked-in files is confusing.
* admin/unidata/Makefile.in (maintainer-clean):
Instead of removing macuvs.h here ...
(extraclean): ... Remove it here.
* admin/unidata/uvs.el (uvs-print-table-ivd):
Add to comment explaining why macuvs.h is in Git.
* src/macuvs.h: Regenerate and re-add to Git.
It can be generated automatically and easily during a normal
bootstrap, so there’s no need to keep it in the repository.
* admin/unidata/Makefile.in (maintainer-clean):
Behave like extraclean and remove macuvs.h etc.
* src/macuvs.h: Remove.
* src/Makefile.in (extraclean): Remove TAGS and config.in.
* Makefile.in (extraclean): Remove info, configure and
emacsver.texi in extraclean.
* admin/unidata/Makefile.in (extraclean): Make it depend on
distclean to remove .elc files.
* leim/Makefile.in (extraclean): Depend on bootstrap-clean to
remove generated .el files.
* lib/Makefile.in (extraclean): Added target to remove sys
directory and run distclean.
* lisp/Makefile.in (extraclean): Also remove loaddefs*.el~ files.
* admin/grammars/grammar.wy: Add %expectedconflicts.
* lisp/cedet/semantic/grammar-wy.el
(semantic-grammar-wy--keyword-table): Ditto.
* lisp/cedet/semantic/grammar.el
(semantic-grammar-expected-conflicts): New function.
(semantic-grammar-insert-defconst-with-eval): New function.
(semantic-grammar-create-package): Output the number of expected
shift/reduce conflicts.
* lisp/cedet/semantic/wisent/comp.el (wisent-total-conflicts):
Don't output the warning if the number of shift/reduce conflicts
is expected.
(wisent-expected-conflicts): Made obsolete.
* admin/grammars/python.wy: Set the expected number of
shift/reduce conflicts to four.
* lisp/cedet/semantic/grammar.el
(semantic-grammar-expected-conflicts): New function.
* lisp/cedet/semantic/wisent/comp.el (wisent-total-conflicts): Use
it to suppress warnings about the expected number of shift/reduce
conflicts.
* admin/grammars/python.wy: Set the expected number of
shift/reduce conflicts to four.
* lisp/cedet/semantic/grammar.el
(semantic-grammar-expected-conflicts): New function.
* lisp/cedet/semantic/wisent/comp.el (wisent-total-conflicts): Use
it to suppress warnings about the expected number of shift/reduce
conflicts.
* admin/grammars/js.wy: Add types to the FALSE, TRUE and QUERY tokens.
Without the types, you'd get the warning
*Warning* default value of <<no-type>> tokens changed to QUERY, was NULL_TOKEN
*Warning* default value of <<no-type>> tokens changed to TRUE, was QUERY
*Warning* default value of <<no-type>> tokens changed to FALSE, was TRUE
I think this should be harmless, and it doesn't seem to break handling
.js files.
Problem with jisx2131-filter reported by Phillip Lord in:
https://lists.gnu.org/r/emacs-devel/2019-06/msg00147.html
* admin/charsets/Makefile.in (SED_SCRIPT):
Put it in $(srcdir), which is not necessarily the working directory.
($(SED_SCRIPT)): Rename from jisx2131-filter. All uses changed.
(clean): Do not remove SED_SCRIPT.
(extraclean): Remove it here instead.
* make-dist (possibly_non_vc_files): Remove src/emacs-module.h.
Although it is portable and could be distributed in the tarball,
it's too much hassle to do that, so let each builder make it.
The copy_file_range syscall (introduced in Linux kernel
version 4.5) can copy files more efficiently via server-side
copy etc.
* admin/merge-gnulib (GNULIB_MODULES): Add copy-file-range.
* lib/copy-file-range.c, m4/copy-file-range.m4:
New files, copied from Gnulib.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* src/fileio.c (Fcopy_file): Try copy_file_range first,
falling back on read+write only if copy_file_range failed or
if the input is empty and so could be a /proc file.
