C11 threads are not needed for Emacs now, and their use is causing
hassles on FreeBSD 10.x. Problem reported by Ashish SHUKLA in:
http://lists.gnu.org/archive/html/emacs-devel/2015-12/msg00648.html
* configure.ac: Do not check for C11 threads. Remove unnecessary
fiddling with CPPFLAGS when configuring pthreads.
* src/emacs-module.c (main_thread, check_main_thread)
(module_init): Do not worry about C11 threads.
This avoids warnings when converting between void * and
function pointers, which strict C11 does not allow.
* configure.ac (dlfunc): Check for existence.
* src/dynlib.c (dlfunc) [!HAVE_DLFUNC]: New macro.
(dynlib_func): New function.
* src/dynlib.h (dynlib_function_ptr, dynlib_func): New decls.
* src/emacs-module.c (Fmodule_load): Use dynlib_func, not
dynlib_sym, for function pointers.
This is mostly indenting and spacing changes. Also, remove
some unnecessary static decls instead of bothering to reindent them.
* src/module.h (EMACS_EXTERN_C_BEGIN): Remove, and do this inline,
as most other Emacs files do for this sort of thing.
* configure.ac: Add '--with-modules' option. Conditionally add
dynlib.o and module.o to the list of objects. Add any system
specific flags to the linker flags to support dynamic libraries.
* m4/ax_gcc_var_attribute.m4: Add autoconf extension to test gcc
attributes.
* src/Makefile.in: Conditionally add module objects and linker flags.
* src/alloc.c (garbage_collect_1): protect module local values from
GC.
* src/lisp.h: Add 'module_init' and 'syms_of_module' prototypes.
* src/emacs_module.h: New header file included by modules. Public
module API.
* src/module.c: New module implementation file.
Co-authored-by: Philipp Stephani <phst@google.com>
* configure.ac: If using X11, check for XCB libraries and header.
* src/Makefile.in (XCB_LIBS): Define.
(LIBX_EXTRA): Include it.
* src/xterm.h [USE_XCB]: Include X11/Xlib-xcb.h.
(struct x_display_info) [USE_XCB]: Add an XCB connection handle field.
* src/xterm.c (x_term_init) [USE_XCB]: Initialize the new field.
POSIX says that ‘echo FOO’ produces implementation-defined output
if FOO contains leading ‘-’, or ‘\’ anywhere, so don’t assume GNU
behavior in that case.
* Makefile.in (removenullpaths): Remove.
(epaths-force): Rewrite to avoid the need for ‘echo’.
(install-etc): Be clearer about escaping the shell metacharacters
‘\’ and ‘$’.
* Makefile.in (install-arch-indep, install-etcdoc):
* admin/charsets/mapconv, admin/merge-gnulib, admin/merge-pkg-config:
* admin/quick-install-emacs, build-aux/gitlog-to-emacslog:
* configure.ac, lib-src/rcs2log, make-dist:
* src/Makefile.in (lisp.mk):
Don’t assume ‘echo’ outputs ‘\’ and leading ‘-’ unscathed.
For example, use ‘printf '%s\n' "$foo"’ rather than ‘echo "$foo"’
if $foo can contain arbitrary characters.
* lisp/Makefile.in (TAGS): Use ‘ls’, not ‘echo’, to avoid ‘\’ issues.
* doc/lispref/two-volume.make (vol1.pdf):
* test/etags/make-src/Makefile (web ftp publish):
Use ‘printf’ rather than ‘echo -e’.
Make --enable-gcc-warnings a bit pickier, by also using -Wswitch.
* configure.ac (WERROR_CFLAGS): Don’t add -Wno-switch.
* lib-src/etags.c (main, consider_token, C_entries):
* src/coding.c (encode_invocation_designation):
* src/data.c (Ftype_of):
* src/eval.c (Fdefvaralias, default_toplevel_binding)
(Fbacktrace__locals, mark_specpdl):
* src/lisp.h (record_xmalloc):
* src/syntax.c (scan_lists, scan_sexps_forward):
* src/window.c (window_relative_x_coord):
* src/xdisp.c (push_it, pop_it):
* src/xterm.c (xg_scroll_callback, x_check_fullscreen):
Error out or do nothing (as appropriate) if a switch statement
with an enum value does not cover all of the enum.
* src/dispextern.h (struct iterator_stack_entry.u.comp):
Remove unused member discovered by using -Wswitch.
* src/lisp.h (record_xmalloc): Add a ‘+ 0’ to pacify -Wswitch.
* src/vm-limit.c (check_memory_limits):
Simplify warning-diagnostic computation by using a table.
Problem reported by Ashish SHUKLA in:
http://lists.gnu.org/archive/html/emacs-devel/2015-09/msg00531.html
* configure.ac: Check for struct unipair.unicode instead of for
<linux/kd.h>, since that’s more specific to what the code actually needs.
* src/terminal.c: Use HAVE_STRUCT_UNIPAIR_UNICODE, not HAVE_LINUX_KD_H.
This should help Emacs work better out-of-the-box on Linux consoles,
which have only limited support for displaying Unicode characters.
Also, undo the recent change that caused text-quoting-style to
affect quote display on terminals, so that the two features are
independent. See Alan Mackenzie in:
http://lists.gnu.org/archive/html/emacs-devel/2015-09/msg00244.html
Finally, add a style parameter to startup--setup-quote-display,
so that this function can also be invoked after startup, with
different styles depending on user preference at the time.
* configure.ac: Check for linux/kd.h header.
* doc/emacs/display.texi (Text Display): Document quote display.
* doc/lispref/display.texi (Active Display Table):
* etc/NEWS:
* lisp/startup.el (startup--setup-quote-display, command-line):
text-quoting-style no longer affects quote display.
* doc/lispref/frames.texi (Terminal Parameters): Fix typo.
* lisp/international/mule-util.el (char-displayable-p):
* lisp/startup.el (startup--setup-quote-display):
On a text terminal supporting glyph codes, use the reported
glyph codes instead of the terminal coding system, as this
is more accurate on the Linux console.
* lisp/startup.el (startup--setup-quote-display):
New optional arg STYLE.
* src/fontset.c (Finternal_char_font):
Report glyph codes for a text terminal, if they are available.
Currently this is supported only for the Linux console.
* src/termhooks.h (struct terminal): New member glyph-code-table.
* src/terminal.c [HAVE_LINUX_KD_H]: Include <errno.h>, <linux/kd.h>.
(calculate_glyph_code_table) [HAVE_LINUX_KD_H]: New function.
(terminal_glyph_code): New function.
* configure.ac (with_file_notification): Fix typo that
prevented suppression of file notification if HAVE_NS.
(NOTIFY_OBJ): Prefer inotify to gfile if both exist and
with_file_notification is 'yes' (Bug#21241).
* etc/NEWS: Mention this.
* src/w32fns.c (w32_reset_stack_overflow_guard)
(stack_overflow_handler): New functions for handling C stack
overflow exceptions.
(my_exception_handler): Handle EXCEPTION_STACK_OVERFLOW exceptions
specially, and zero out except_addr if we do.
(globals_of_w32fns): Initialize dwMainThreadId in non-interactive
mode.
* src/sysdep.c [HAVE_STACK_OVERFLOW_HANDLING]: Add !WINDOWSNT to
the condition, as HAVE_STACK_OVERFLOW_HANDLING is now defined for
the MinGW build, but the code guarded by that is for Posix hosts.
* src/keyboard.c (command_loop) [WINDOWSNT]: Call
w32_reset_stack_overflow_guard.
* nt/inc/ms-w32.h (sigjmp_buf): New typedef.
(sigsetjmp): New macro.
(w32_reset_stack_overflow_guard): Declare the prototype.
* configure.ac (HAVE_STACK_OVERFLOW_HANDLING): Set to 1 for MinGW.
This simplifies time conversions in other time zones.
It also prevents display-time-world tampering with TZ (Bug#21020).
* admin/admin.el (add-release-logs):
Use improved add-log-time-format API.
* admin/merge-gnulib (GNULIB_MODULES): Add time_rz, timegm.
(GNULIB_TOOL_FLAGS): Avoid flexmember, setenv, unsetenv.
* configure.ac (tzalloc): Remove test for this, since
Emacs no longer uses HAVE_TZALLOC directly.
* doc/lispref/os.texi (Time of Day, Time Conversion)
(Time Parsing):
* etc/NEWS: Document the new behavior.
Merge from gnulib, incorporating:
2015-07-25 strftime: fix newly-introduced bug on Solaris
2015-07-23 fprintftime, strftime: use timezone_t args
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* lib/strftime.c, lib/strftime.h, lib/time.in.h, m4/sys_time_h.m4:
* m4/time_h.m4:
Update from gnulib.
* lib/time_rz.c, lib/timegm.c, m4/time_rz.m4, m4/timegm.m4:
New files from gnulib.
* lisp/time-stamp.el (time-stamp-string):
* lisp/time.el (display-time-world-list)
(display-time-world-display):
Use new API, with time zone arg.
* lisp/time.el (display-time-world-display):
Fix race when current-time advances while we're running.
* lisp/vc/add-log.el (add-log-iso8601-time-zone)
(add-log-iso8601-time-string): Accept optional time zone arg.
* lisp/vc/add-log.el (add-change-log-entry):
* lisp/vc/log-edit.el (log-edit-changelog-ours-p): Use new arg.
* nt/gnulib.mk: Propagate lib/gnulib.mk changes here.
Add rules for the time module, since they're now needed
for tzalloc etc.
* src/conf_post.h (getenv_TZ, setenv_TZ): New macros.
(emacs_getenv_TZ, emacs_setenv_TZ): New decls.
* src/editfns.c: Include errno.h.
(set_time_zone_rule): Omit unnecessary forward decl.
(initial_tz): Remove, replacing with ...
(local_tz, wall_clock_tz, utc_tz): New static vars and constants.
(tzeqlen): New constant; prefer it to (sizeof "TZ=" - 1).
(emacs_localtime_rz, emacs_mktime_z, xtzalloc, xtzfree)
(tzlookup): New static functions.
(init_editfns): New arg DUMPING. All uses changed.
(init_editfns): Omit most initialization if dumping, not if
!initialized. Initialize wall_clock_tz and local_tz.
(emacs_nmemftime, format_time_string): Time zone argument can now
be any time zone, not just a boolean for UTC or local time. All
callers changed.
(Fformat_time_string, Fencode_time, Fcurrent_time_string)
(Fcurrent_time_zone): New optional arg ZONE.
(Fdecode_time, Fset_time_zone_rule): ZONE arg can now also take
the same form as with the other new additions.
(decode_time_zone): Remove; no longer needed.
(tzvalbuf): Now file-scope.
(emacs_getenv_TZ, emacs_setenv_TZ): New functions.
(syms_of_editfns): Define Qwall.
* src/editfns.c (mktime_z) [!HAVE_TZALLOC]:
* src/systime.h (mktime_z, timezone_t, tzalloc, tzfree)
[!HAVE_TZALLOC]:
Remove; now supplied by gnulib.
* src/emacs.c (main):
* src/lisp.h (init_editfns): Adjust to init_editfns API change.
* configure.ac (SETUP_SLAVE_PTY) [sol2* | unixware]:
Adjust to process.c change.
* src/process.c (create_process): Declare volatile variables at
top level of this function, so that they're less likely to be
reused later in the function in the code executed by the vforked
child. Do not declare locals used only in the vforked child, as
they might share memory with locals still live in the parent.
Instead, use the same variables in the child as in the parent.
This works around a subtle bug that causes a garbage collector
crash when Emacs is built with Sun C 5.13 sparc on Solaris 10.
* configure.ac (PTY_OPEN): Define to plain 'open'
on SVR4-derived hosts, so that the O_CLOEXEC flag isn't set.
* src/process.c (allocate_pty): Set the O_CLOEXEC flag after
calling PTY_TTY_NAME_SPRINTF, for the benefit of SVR4-derived
hosts that call grantpt which does its work via a setuid subcommand
(Bug#19191, Bug#19927, Bug#20555, Bug#20686).
Also, set O_CLOEXEC even if PTY_OPEN is not defined, since it
seems relevant in that case too.
* configure.ac (SUBDIR_MAKEFILES): Add admin/charsets/Makefile.
(admin/charsets/Makefile): Generate it.
* admin/charsets/Makefile.in: Rename from Makefile.
(AWK, srcdir, top_srcdir, AM_DEFAULT_VERBOSITY):
New variables, set by configure.
(charsetdir, lispintdir, mapfiledir, AM_V_GEN, am__v_GEN_)
(am__v_GEN_0, am__v_GEN_1, AM_V_at, am__v_at_, am__v_at_0)
(am__v_at_1, LOCAL, mapconv, run_mapconv, big5, compact, cp51932)
(cp932, eucjp_ms, gb180302, gb180304, kuten): New variables.
(TRANS_TABLE, CHARSETS): Add directory prefix to value.
(all): Declare PHONY.
(local): New PHONY target.
(map_template): New template. Use to define short PHONY aliases.
(*.map): Add directory prefixes to targets and prerequisites.
Respect make verbosity.
(JISC6226.map): Replace non-portable sed append without newline.
(install): Remove rule.
(clean): Only delete temporary sedscript.
(bootstrap-clean, distclean, maintainer-clean, extraclean)
(totalclean): New PHONY rules.
* admin/charsets/mapconv (BASE): Replace basename with expr.
(FILE): Add "mapfiles" subdirectory.
(AWK): New variable. Use throughout in place of "awk".
(main): Use "gunzip -c" in place of "zcat".
Don't leave whitespace before "p", for older sed.
* admin/charsets/mapfiles/PTCP154: Add final newline,
to make older sed versions happy.
; * .gitignore: Ignore admin/charsets/Makefile.
* configure.ac (DEPDIR, MKDEPDIR, deps_frag, lwlib_deps_frag)
(oldxmenu_deps_frag, lisp_frag): Remove output variables/files.
(AUTO_DEPEND): New output variable.
* lwlib/Makefile.in (AUTO_DEPEND): New, set by configure.
(DEPFLAGS, MKDEPDIR): Set directly via conditional.
(lwlib_deps_frag): Replace by conditional include.
* lwlib/autodeps.mk: Remove file.
* oldXMenu/Makefile.in (AUTO_DEPEND): New, set by configure.
(DEPFLAGS, MKDEPDIR): Set directly via conditional.
(oldxmenu_deps_frag): Replace by conditional include.
* oldXMenu/autodeps.mk: Remove file.
* src/Makefile.in (AUTO_DEPEND): New, set by configure.
(DEPFLAGS, MKDEPDIR): Set directly via conditional.
(lisp_frag): Replace by an include.
(deps_frag): Replace by conditional include.
* src/autodeps.mk: Remove file.
* configure.ac: Check for jpeglib 6b by trying to link it, instead
of relying on cpp magic that has problems in practice. Check for
both jpeglib.h and jerror.h features. Remove special case for
mingw32, which should no longer be needed (and if it were needed,
should now be addressable by hotwiring emacs_cv_jpeglib).
Fixes: bug#20332
* configure.ac: Allow rsvg with cairo. Move back HAVE_RSVG.
* src/dispextern.h (struct image): add cr_data2 if cairo.
* src/image.c: #undef COLOR_TABLE_SUPPORT when USE_CAIRO.
(x_clear_image): Free cr_data and cr_data2 if set.
(xpm_load): Assign data to cr_data2.
(svg_load_image): Convert from GdkPixbuf to CAIRO_FORMAT_ARGB32.
* configure.ac: Add -Wno-unknown-attributes if clang; otherwise
clang 3.5.0 (Fedora 21 x86-64) complains
"/usr/include/glib-2.0/glib/gmem.h: ... warning: unknown attribute
'__alloc_size__' ignored". Use -Werror when checking for -nopie;
otherwise clang warns about -nopie instead of failing, and then
later it warns everytime the build uses -nopie.
* configure.ac (HAVE_RSVG): Move after cairo.
(USE_CAIRO): Disable rsvg, don't disable Xpm.
* src/image.c (prepare_image_for_display): Don't load if USE_CAIRO.
(x_clear_image): If USE_CAIRO, also free possible img->ximg->obdata and
don't return early.
(ALLOC_XPM_COLORS): Don't define when USE_CAIRO.
(xpm_load): Convert simple Xpms (32 bit ZPixmap) to CAIRO_FORMAT_ARGB32
and create a surface.
