* lib-src/seccomp-filter.c (MAP_DROPPABLE): Define if undefined.
(main): Use MAP_DROPPABLE flag. Allow `tcgetattr' call of glibc
on physical terminal devices. (Bug#77232)
Problem: In Ruby we can define a nested module/class the safe
way (in the sense, if the parent module does not exist, it will
define it:
module M
module N
end
end
If M already exists, we can also write:
module M::N; end
With the later notation, the tag generated by etags will be M::N.
When browsing the code, using xref-find-definitions when the point
is on N, will not be able to find the definition of N because the
implicit tag name is M::N.
This is the same problem with nested classes or even some rare
allowed definitions like explicitely defining a module/class from
the global namespace:
class ::A; end
Solution: We need to give an explicit tag name. To achieve this,
on module/class definition we truncate the name to the last found
column.
* lib-src/etags.c (Ruby_functions): Support "::" in module
definitions.
* test/manual/etags/README: Update instructions.
* test/manual/etags/ruby-src/test1.ru: Add identifiers with "::".

Copyright-paperwork-exempt: yes
Remove our old ctags and suggest Universal Ctags instead.
This fixes a FIXME in lib-src/Makefile.in and speeds up compilation
quite a bit on my older CPU when I compile with --enable-gcc-warnings.
It also lessens installation and runtime footprint. (Bug#76322)
* .gitignore: Remove lib-src/ctags.
* admin/authors.el (authors-renamed-files-alist): Remove ctags.1.
* admin/check-man-pages: ctags.1 is no longer a special case.

* cross/Makefile.in (LIBSRC_BINARIES): Remove lib-src/ctags.
* doc/man/ctags.1, lib-src/ctags.c: Remove.
* java/Makefile.in (CROSS_LIBSRC_BINS): Remove ctags.
* lib-src/Makefile.in (INSTALLABLES): Remove ctags${EXEEXT}.
(ctags${EXEEXT}): Remove.
* lib-src/etags.c (CTAGS): Remove. All uses replaced by ...
(ctags): ... this new static var.
(STDIN): Remove macro. All uses replaced by new STDIN_OPTION constant.
(CTAGS_OPTION, STDIN_OPTION): New contants.
(longopts): New --ctags option.
(ctags_default_C_help): New constant,
to override default_C_help at runtime.
(default_C_help): Now always the etags version.
(C_LANG_NAMES_INDEX): New macro.
(print_language_names): Do not assume etags.
(PROGRAM_NAME): Remove. All uses removed.
(print_help): Document --ctags if PRINT_UNDOCUMENTED_OPTIONS_HELP.
(main): Support new --ctags option, and support all [ce]tags options.
* test/manual/etags/Makefile (CTAGS_PROG):
Now etags --ctags, since there is no longer a ctags.
* lib-src/etags.c (regex_tag_multiline): Fix off-by-one error in
determining the end of the tag matched by a multiline regexp.
(Bug#73771)
* test/manual/etags/ETAGS.good_4:
* test/manual/etags/ETAGS.good_5:
* test/manual/etags/ETAGS.good_6: Adjust test results to the above
change.
This adds '--no-fallback-lang' and '--no-empty-file-entries'
options, and their opposites '--fallback-lang' and
'--empty-file-entries'.
* lib-src/etags.c (fallback_lang, empty_files): New toggles.
(main): Initialize them to 'true'.
(longopts) [!CTAGS]: Add the '--(no-)fallback-lang' and
'--(no-)empty-file-entries' options.
(find_entries): If 'fallback_lang' is false, don't attempt Fortran
and C/C++ fallbacks.
(print_help): Add help for new options.
(main): If 'empty_files' is false, don't output file entries for
files that have no tags. (Bug#73484)
* doc/emacs/maintaining.texi (Create Tags Table):
* etc/NEWS:
* doc/man/etags.1: Document the new options.
* test/manual/etags/Makefile (check): Add test for new options.
* test/manual/etags/ETAGS.good_7: New file.
This fixes some unlikely bugs and removes the temptation
of using ctype.h. Although some uses were correct,
many weren't.
* lib-src/ebrowse.c: Include c-ctype.h, not ctype.h.
* lib-src/emacsclient.c: Include c-ctype.h, not ctype.h.
* lib-src/update-game-score.c: Include c-ctype.h, not ctype.h.
All uses changed.
In addition to providing a new `xref' backend, the patch also improves
the general handling of expl3 syntax. Expl3 is the next-generation
LaTeX specification, and has for some time been available by default in
the LaTeX kernel. The new syntax co-exists in many files with the
standard LaTeX2e syntax, so we try at least minimally to separate the
way modes handle the two specifications, both to reduce
visually-disturbing interference between them and also to improve the
`xref' backend. (Bug#53749)
* lib-src/etags.c (TeX_commands): Improve parsing of commands in TeX
buffers.
(TEX_defenv): Expand list of commands to tag by default in TeX buffers.
(TeX_help):
* doc/emacs/maintaining.texi (Tag Syntax): Document new tagged commands.
(Identifier Search): Add note about semantic-symref-filepattern-alist,
auto-mode-alist, and xref-find-references.
* lisp/textmodes/tex-mode.el (tex-font-lock-suscript): Test for
underscore in expl3 files and regions, disable subscript face there.
(tex-common-initialization): Set up xref backend for in-tree TeX modes.
Detect expl3 files, and in others set up a list of expl3 regions.
(tex-expl-buffer-parse): New function called in previous.
(tex-expl-buffer-p): New variable to hold the result of previous.
(tex-expl-region-set): New function added to
'syntax-propertize-extend-region-functions' hook.
(tex-expl-region-list): New variable to hold the result of previous.
(tex--xref-backend): New function to identify the xref backend.
(tex--thing-at-point, tex-thingatpt--beginning-of-symbol)
(tex-thingatpt--end-of-symbol, tex--bounds-of-symbol-at-point):
New functions to return 'thing-at-point' for xref backend.
(tex-thingatpt-exclude-chars): New variable to do the same.
(xref-backend-identifier-at-point): New TeX backend method to provide
symbols for processing by xref.
(xref-backend-identifier-completion-table)
(xref-backend-identifier-completion-ignore-case)
(xref-backend-definitions, xref-backend-apropos): Placeholders to
call the standard 'etags' xref backend methods.
(xref-backend-references): Wrapper to call the default xref backend
method, finding as many relevant files as possible and using a bespoke
syntax-propertize-function when required.
(tex--collect-file-extensions, tex-xref-syntax-function): Helper
functions for previous.
(tex-find-references-syntax-table, tex--buffers-list)
(tex--xref-syntax-fun, tex--old-syntax-function): New variables for
the same.
d6726e6dfc Further fix of reading and writing profiler data
30b2fae77b * Makefile.in (PREFERRED_BRANCH): Update to emacs-30.
5397808e5b ; Eliminate more C++ comments
1463434907 ; Eliminate C++ comments and typo
* lib-src/etags.c (C_entries): A comma is not special inside class
parameters <..>. (Bug#72402)
(hash, in_word_set): Regenerated after adding "@SuppressWarnings"
to wordlist[]. This avoids missing tags preceded by
"@SuppressWarnings".
I found this problem while looking into Bug#72641.
* lib-src/etags.c (do_move_file):
* lib-src/update-game-score.c (unlock_file):
* src/androidvfs.c (android_hack_asset_fd_fallback):
* src/filelock.c (current_lock_owner):
Treat unlink as successful if it fails because the file wasn’t there.
This can happen with some NFS implementations, due to its
retrying over the network to get at-least-once semantics.
Although most of Emacs’s calls to unlink were already doing this,
a few instances were not.
* java/Makefile.in (install_temp): Do not compress
directory-tree and generate such files in a special format that
stores file sizes.
* lib-src/asset-directory-tool.c (struct directory_tree): New
field st_size.
(need_file_size): New variable.
(main_1, main_2, main): Write file sizes before sibling offsets
if `--api-8' is specified.
* src/android-asset.h (struct android_asset_manager): New field
open.
(struct android_asset): New field name.
(AAssetManager_fromJava): Load AssetManager#open.
(AAssetManager_open): If a directory tree has already been
loaded, search for a matching asset and load its size thence, to
avoid the requirement of an AssetFileDescriptor.
(AAsset_close): Don't assume asset->fd exists. Release
asset->name.
(AAsset_getLength): Likewise.
(android_asset_create_stream): If asset->name exists, call
AssetManager#open, in order to open compressed files.
* src/androidvfs.c (OLD_ANDROID_ASSETS): Define to 1 on API 8.
(android_extract_long, android_scan_directory_tree): Mark
arguments as const. Adjust offsets when OLD_ANDROID_ASSETS.
(android_is_directory, android_init_assets, android_afs_readdir):
Likewise.
* src/lread.c (lread_fstat): Define to sys_fstat, not fstat.
This is a new warning diagnostic in GCC 14.
* lib-src/etags.c (mercury_heuristics_ratio):
* src/pgtkselect.c, src/xselect.c (selection_request_stack):
* src/xselect.c (outstanding_transfers):
* src/xterm.c (pending_selection_requests)
(x_dnd_waiting_for_motif_finish_display):
Now static.
* lib-src/make-docfile.c (close_emacs_globals):
Arrange for lispsym to be declared with extern first,
when compiling lread.c.
* src/alloc.c (gdb_make_enums_visible) [__GNUC__]:
* src/emacs.c (RCS_Id):
* src/keyboard.c (stop_character):
* src/print.c (print_output_debug_flag):
Now declared with extern first.
* src/lisp.h (DEFINE_GDB_SYMBOL_BEGIN) [MAIN_PROGRAM]:
Arrange for ID to be declared extern first.
* src/lisp.h (garbage_collection_inhibited):
* src/xterm.h (x_frame_parm_handlers):
Declare here, so that its interface is properly checked. Other decls
removed.
* lib-src/etags.c: Ignore -Wanalyzer-use-of-uninitialized-value.
This applies to the whole source file, not just to areas where GCC
has bugs, as it was too tricky to ignore more selectively.
* lib-src/etags.c (readline): Don’t mishandle lines like
‘#line 1 "a//"’, which has an escaped backslash before ‘"’.
Don’t mishandle lines so long that sscanf overflows %n.
* lib-src/etags.c (xnew): Remove. All uses removed.
xnew was confusing, as sometimes it was used with n=1,
sometimes with Type=char, and it’s easier just to use xmalloc
or xnmalloc.
Problem reported by Collin Funk (Bug#68996).
* GNUmakefile (.): New macro.
(help): Use ‘$.’ instead of ‘$ ’.
* cross/verbose.mk.android, src/verbose.mk.in (.): New macro.
(AM_V_AR, AM_V_CC, AM_V_CXX, AM_V_CCLD, AM_V_CXXLD, AM_V_GEN):
Use ‘$.’ instead of ‘$ ’.
* lib-src/Makefile.in (install): Use ‘$.’ instead of ‘$ ’.
Be more systematic about putting space before paren in calls,
and in avoiding unnecessary parentheses in macros.
This was partly inspired by my wading through gcc -E output
while debugging something else, and seeing too many parens.
This patch does not change the generated .o files on my platform.
* java/org/gnu/emacs/EmacsPixmap.java (EmacsPixmap): Make
dimensions final, since they are never changed after the
constructor.
* lib-src/emacsclient.c (decode_options): If --display is not
provided, always set display to `android' even if DISPLAY is
provided.
* lisp/net/browse-url.el (browse-url): Cease setting DISPLAY
under Android.
* src/callproc.c (getenv_internal, make_environment_block):
Don't afford DISPLAY special treatment under Android.
This is mostly to avoid interface hassles with time/srand/rand.
* lib-src/update-game-score.c (main): Don’t use ‘srand’ or ‘time’.
(lock_file): Don’t sleep if we unlocked the lock file. When
sleeping, always just sleep 1 s. This avoids the need for calling
‘time’ and ‘rand’, the utility of which was dubious anyway.
* lib-src/movemail.c (mbx_delimit_begin): Use ‘current_timespec’
instead of ‘time’ to generate the user-visible timestamp.
This works around the minor glitch caused by glibc bug 30200
<https://sourceware.org/bugzilla/show_bug.cgi?id=30200>.
