Do not assume that the natural alignment of Lisp objects is a
multiple of GCALIGNMENT. This improves on the portability of the
recent fix for Bug#29040.
* lib-src/make-docfile.c (close_emacs_globals):
* src/buffer.c (buffer_defaults, buffer_local_symbols):
* src/lisp.h (DEFUN):
* src/thread.c (main_thread):
Use GCALIGNED, not alignas (GCALIGNMENT).
* src/alloc.c (COMMON_MULTIPLE):
Move back here from lisp.h, since it is no longer used elsewhere.
* src/lisp.h (GCALIGNMENT): No longer a macro, since we need not
worry about MSVC. Omit no-longer-needed consistency check.
* src/thread.c (THREAD_ALIGNMENT): Remove.
These fixes were suggested by Drew Adams.
* src/window.c (Fminibuffer_selected_window): Disambiguate
doc-string.
* doc/lispref/minibuf.texi (Intro to Minibuffers)
(Minibuffer Windows, Recursive Mini, Minibuffer Misc): Avoid
the term "currently active minibuffer window". Disambiguate
documentation of `minibuffer-selected-window'.
* src/lisp.h (COMMON_MULTIPLE): Move here from alloc.c.
* src/thread.c (THREAD_ALIGNMENT): New macro.
(main_thread): Use THREAD_ALIGNMENT to align propertly. (Bug#29040)
* src/fileio.c (Fset_default_file_modes): Doc fix. (Bug#28875)
* doc/lispref/files.texi (Changing Files): Clarify how the bits in
the argument of set-default-file-modes are used for setting file
permissions.
* src/doc.c (Fdocumentation): Restore the pre-25 behavior
of signalling a void-function error for an undefined function.
This seems cleaner than Emacs 25's "invalid-function: nil" error,
which was (probably) an unintended consequence of changes to
Findirect_function.
These changes also update the various bundled packages to use
new feature, and better support customizations of the line-number
face.
* src/xdisp.c (calc_pixel_width_or_height): Improve commentary.
Make :align-to count from the end of the line-number display when
the offset or the width form reference that of the text area.
(Bug#28855)
* src/indent.c (Fline_number_display_width): Implement support for
the PIXELWISE argument being 'columns'. Update the doc string.
(syms_of_indent): New symbol 'columns'.
* lisp/ruler-mode.el (ruler-mode-window-col, ruler-mode-ruler):
Call line-number-display-width with last argument 'columns'.
* lisp/proced.el (proced-header-line): Call
line-number-display-width with 2nd arg 'columns', which also fixes
a problem when display-line-numbers is nil.
* lisp/emacs-lisp/tabulated-list.el
(tabulated-list-line-number-width): Call line-number-display-width
with 2nd arg 'columns.
(tabulated-list-entry-lnum-width): Remove unneeded defvar.
(tabulated-list-print, tabulated-list-print-entry): No need to
account for the value of tabulated-list-entry-lnum-width.
(tabulated-list--current-lnum-width): New defvar.
(tabulated-list-watch-line-number-width): New function.
(tabulated-list-mode): Bind tabulated-list--current-lnum-width
locally, and set up tabulated-list-watch-line-number-width as
pre-redisplay-functions hook.
* doc/lispref/display.texi (Size of Displayed Text): Document the
'columns' value of the PIXELWISE argument.
(Pixel Specification): Update and improve the documentation of the
supported forms.
* msdos/sed1v2.inp (GETADDRINFO_A_LIBS, LIBLCMS2, XDBE_LIBS)
(XDBE_FLAGS, HYBRID_MALLOC, LIBSYSTEMD_CFLAGS)
(LIBSYSTEMD_LIBS): Edit to empty.
(LIBRESOLV, DEPFLAGS, MKDEPDIR, YMF_PASS_LDFLAGS)
(PRE_EDIT_LDFLAGS, POST_EDIT_LDFLAGS): Remove editing.
Remove editing of lines that are no longer present in
src/Makefile.in.
* msdos/sed2v2.inp (NEED_MKTIME_INTERNAL)
(NEED_MKTIME_WORKING): Define to 1.
(HAVE_STRUCT_DIRENT_D_TYPE): Define to 1 for
DJGPP >= 2.05.
(HAVE_STRUCT_ATTRIBUTE_ALIGNED): Define to 1.
Define PACKAGE_VERSION, not VERSION.
(FLEXIBLE_ARRAY_MEMBER): Define to empty.
(HAVE_DECL_*_UNLOCKED): Define to 0.
(HAVE___BUILTIN_FRAME_ADDRESS): Define to 1.
(PENDING_*): Don't define, as Gnulib no longer supports that.
Instead, define _IOERR as it is in libc/file.h.
* msdos/sed3v2.inp: Use $(CURDIR) instead of $(shell cd) to
determine the current directory.
(UPDATE_MANIFEST, UTILITIES): Don't edit.
* msdos/sedlisp.inp (FIND_DELETE): Edit to "-delete".
* msdos/sedlibmk.inp (AUTO_DEPEND): Define to yes.
(HYBRID_MALLOC): Edit to empty.
(am__cd): Don't edit.
(../config.status): Replaces $(top_builddir)/config.status.
Define OMIT_GNULIB_MODULE_foo = true for modules not built for
MS-DOS. Convert GL_GENERATE_xxx_H_TRUE and
GL_GENERATE_xxx_H_FALSE into values of GL_GENERATE_xxx_H.
* msdos/mainmake.v2 (src): Use 'compile-one-process', and make
the command line shorter to fit into 126-char limit of
command.com.
* config.bat: Generate src/deps/*.d files. Rename more files
like djtar on plain DOS would.
Don't rename src/dir.h: it is long gone. Edit
lib/gnulib.mk.in using the same scripts as for
lib/Makefile.in.
* msdos/depfiles.bat: Create *.d files, not *.Po.
* src/thread.c (Fmake_thread) [!THREADS_ENABLED]: Improve the
error message.
* src/thread.h [MSDOS]: Include <signal.h>.
* src/sysselect.h (select) [MSDOS]: Undefine, to avoid
compilation errors.
* src/sysdep.c (block_interrupt_signal, restore_signal_mask):
Expose to MSDOS build.
* src/process.c (update_processes_for_thread_death)
[!subprocess]: No-op implementation.
[HAVE_SETRLIMIT]: Move inclusion of sys/resource.h and
declaration of nofile_limit outside "#ifdef subprocesses", as
it's needed for MSDOS.
* src/msdos.c (faccessat): Declare fullname[].
* src/msdos.h (ENOTSUP): Define to be identical to ENOSYS.
Include termhooks.h.
* src/conf_post.h [WINDOWSNT]: Include ms-w32.h only on
WINDOWSNT, not DOS_NT.
* admin/admin.el (set-version): Set version on PACKAGE_VERSION.
* doc/lispref/os.texi (Time Parsing): Fix some errors in the
documentation for format-time-string. Document ^, #, %s, and %z
with colons. Say that unrecognized sequences are output as-is.
* src/editfns.c (Fformat_time_string): %S can stand for 60.
Also mention unrecognized sequences.
This should fix several bugs reported recently against Emacs
(Bug#28518, Bug#28626, Bug#28632, Bug#28633, Bug#28770).
* src/image.c (imagemagick_load_image):
Do not call MagickWandTerminus.
* src/indent.c (line_number_display_width): Make sure a line
number is generated even when the first line of the window is
completely hscrolled out of view. (Bug#28854)
Problem reported by Roland Winkler (Bug#28824#35).
Based on a patch proposed by Andy Moreton (Bug#28824#38).
* src/image.c (pbm_scan_index): New function.
(pbm_load): Use it to decode raw data correctly when its top bit
is set.
Make the effect of customizing arabic-shaper-ZWNJ-handling appear
immediately.
* lisp/language/misc-lang.el (arabic-shaper-ZWNJ-handling): Add :set
value.
* src/composite.c (Fclear_composition_cache): New function.
(syms_of_composite): Defsubr it.
* src/systhread.c: Include w32term.h instead of windows.h.
(w32_beginthread_wrapper): Add ALIGN_STACK attribute, to ensure
the thread's stack is correctly aligned.
* src/w32term.h (ALIGN_STACK): Update commentary.
* src/gnutls.c (HAVE_GNUTLS_MAC_GET_NONCE_SIZE)
[GNUTLS_VERSION_NUMBER >= 0x030300]: Define.
(gnutls_mac_get_nonce_size): Depend on
HAVE_GNUTLS_MAC_GET_NONCE_SIZE.
(Fgnutls_macs): Use 0 for :mac-algorithm-noncesize if
!HAVE_GNUTLS_MAC_GET_NONCE_SIZE.
Problem diagnosed by Andreas Schwab (Bug#28792#65).
This fixes a bug that I introduced in
2017-09-10T22:39:24@eggert@cs.ucla.edu
"Fix race with rename-file etc. with dir NEWNAME".
* src/fileio.c (Frename_file): Copy a source directory across
file system boundaries even if its name does not end in slash.
* src/sysdep.c (get_current_dir_name_or_unreachable):
Avoid integer overflow if working directory name is absurdly long.
When allocating memory for getcwd, do not exceed MAXPATHLEN.
* src/xdisp.c (redisplay_window): Clear the window's desired glyph
matrix before calling try_window with the same starting point.
This avoids assertion violations when switching from a buffer
without line numbers to a buffer with line numbers. (Bug28710)
* src/sysdep.c (get_current_dir_name_or_unreachable):
New function, with most of the old contents of
emacs_get_current_dir_name.
(emacs_get_current_dir_name): Use it. Use a simpler
test for unreachable directory strings, and also apply
it to getcwd etc. (Bug#27871)
* src/dispnew.c (update_frame_line): Accept an additional argument
UPDATING_MENU_P; if non-zero, home the cursor before updating a
frame's line. All callers changed.
(update_frame_1): Accept an additional argument UPDATING_MENU_P,
and pass it to update_frame_line. All callers changed.
(update_frame_with_menu): Call update_frame_1 with last argument
non-zero. (Bug#17497)
Problem reported by Kaushal Modi in:
http://lists.gnu.org/archive/html/emacs-devel/2017-10/msg00141.html
* src/editfns.c (styled_format): Fix bug where USE_SAFE_ALLOCA was
not always followed by SAFE_FREE. This bug was introduced in my
patch 2017-09-26T23:31:57Z!eggert@cs.ucla.edu entitled "Avoid some
unnecessary copying in Fformat etc."
