* src/inotify.c (INOTIFY_DEFAULT_MASK): Removing ACCESS, OPEN
and CLOSE events on order do let other processes also reading
from their descriptors. (Bug#26973).
* src/nsterm.h [NS_IMPL_GNUSTEP]: Add typedefs for Cocoa-only types.
(NSWindowStyleMaskUtilityWindow): #define to NSUtilityWindowMask in
GNUstep and old versions of macOS.
* src/nsfns.m (ns-set-mouse-absolute-pixel-position): Function only
works in cocoa, not GNUstep.
Module functions were previously called "function environments" when
the functions created by module_make_functions were lambdas. Now we
can adapt the terminology and rename "function environments" to
"module functions" everywhere. This also removes the name clash
between "function environments" and "module environments."
* src/emacs-module.c (module_make_function): Adapt comment to reality;
stop using "function environment" terminology.
(funcall_module): Stop using "function environment" terminology.
* src/nsfns.m (Fns_list_services): Remove unreachable code. In this
branch NS_IMPL_COCOA cannot be defined.
(interpret_services_menu): Define only if called to avoid compiler
warnings about unused static functions.
* src/nsterm.m (mouseDown:):
* src/nsmenu.m (runMenuAt:forFrame:keymaps:): Remove call to
deprecated method. The return value is always nil.
* src/macfont.m (mac_font_shape_1): Replace call to deprecated method.
These semicolons are ignored and cause compiler warnings.
* src/nsimage.m (setPixelAtX:Y:toRed:green:blue:alpha:):
* src/nsterm.m (init, updateFrameSize:):
(setFrame:): Remove trailing semicolon.
This should not cause behavior changes, but fixes a compiler warning
due to implicit conversions between the enums.
* src/macfont.m (macfont_cache, macfont_lookup_cache)
(macfont_get_glyph_for_cid, macfont_get_uvs_table)
(macfont_variation_glyphs): Use NSCharacterCollection.
"%o" will display the percentage "travel" of the window through the buffer.
"%q" will display a combination of the percentage offsets of the top and
bottom of the window. The new user option mode-line-percent-position will
facilitate selecting a setting for this part of the mode line.
* lisp/bindings.el (mode-line-percent-position): New customizable user option.
(mode-line-position): Use mode-line-percent-position in place of "%p", etc.
* src/xdisp.c (decode_mode_spec): Add handlers for "%o" and "%q".
* doc/lispref/modes.texi (Mode Line Variables): Document
mode-line-percent-position.
(%-Constructs): Document %o and %q.
* etc/NEWS: Add an entry for these new facilities.
* src/print.c (print_vectorlike): New function, taken from
part of print_object. This one is indented properly, and
pacifies --enable-gcc-warnings by using a default case
instead of listing all the enum values, sometimes
incompletely.
(print_object): Use it.
It does not appear to be needed (Bug#24441).
* etc/PROBLEMS: Remove DARWIN_OS_CASE_SENSITIVE_FIXME stuff.
* src/fileio.c (file_name_case_insensitive_p):
Remove DARWIN_OS_CASE_SENSITIVE_FIXME code.
* etc/PROBLEMS: Document this (Bug#24441).
* src/fileio.c (file_name_case_insensitive_p): Prefer pathconf
with _PC_CASE_SENSITIVE, if it works, to
DARWIN_OS_CASE_SENSITIVE_FIXME code.
Support just one method for DARWIN_OS_CASE_SENSITIVE_FIXME,
which matches the Apple documentation more precisely.
* lisp/frame.el (ns-set-mouse-absolute-pixel-position): New
function (Lisp).
(set-mouse-absolute-pixel-position): Change it to call
`ns-set-mouse-absolute-pixel-position' on macOS.
* src/nsfns.m (Fns_set_mouse_absolute_pixel_position): New
function.
* src/nsterm.h (NS_PARENT_WINDOW_TOP_POS): Use the primary
screen's height as a base for calculating global coordinates.
* src/nsterm.m (frame_set_mouse_pixel_position): Fix it in macOS.
* test/lisp/mouse-tests.el (bug26816-mouse-frame-movement): Test
movement of mouse relative to frame.
* src/emacs-module.c (module_make_function):
Check that arities fit into fixnums, for func-arity’s benefit.
(funcall_module): Avoid unnecessary conversion to EMACS_INT.
(module_function_arity): Allow arities greater than SHRT_MAX.
Instead of a lambda, create a new type containing all data required to
call the function, and support it in the evaluator. Because this type
now also needs to store the function documentation, it is too big for
Lisp_Misc; use a pseudovector instead. That also has the nice benefit
that we don't have to add special support to the garbage collector.
Since the new type is user-visible, give it a predicate.
Now we can easily support 'help-function-args' and 'func-arity'; add
unit tests for these.
* src/lisp.h (allocate_module_function, MODULE_FUNCTIONP)
(XMODULE_FUNCTION): New pseudovector type 'module function'.
* src/eval.c (FUNCTIONP): Also treat module functions as functions.
(funcall_lambda, Ffuncall, eval_sub): Add support for calling module
functions.
(Ffunc_arity): Add support for detecting the arity of module
functions.
* src/emacs-module.c (module_make_function): Adapt to new structure.
Return module function object directly instead of wrapping it in a
lambda; remove FIXME.
(funcall_module): New function to call module functions. Replaces
`internal--module-call' and is called directly from eval.c.
(syms_of_module): Remove internal helper function, which is no longer
needed.
(module_function_arity): New helper function.
* src/data.c (Ftype_of): Adapt to new implementation.
(Fmodule_function_p, syms_of_data): New user-visible function. Now
that module functions are first-class objects, they deserve a
predicate. Define it even if not compiled with --enable-modules so
that Lisp code doesn't have to check for the function's existence.
* src/doc.c (Fdocumentation): Support module functions.
* src/print.c (print_object): Adapt to new implementation.
* src/alloc.c (mark_object): Specialized garbage collector support is
no longer needed.
* lisp/help.el (help-function-arglist): Support module functions.
While there, simplify the arity calculation by using `func-arity',
which does the right thing for all kinds of functions.
* test/data/emacs-module/mod-test.c: Amend docstring so we can test
the argument list.
* test/src/emacs-module-tests.el (mod-test-sum-docstring): Adapt to
new docstring.
(mod-test-non-local-exit-signal-test): Because `internal--module-call'
is gone, the backtrace has changed and no longer leaks the
implementation.
(module--func-arity): New test for `func-arity'.
(module--help-function-arglist): New test for `help-function-arglist'.
* src/xdisp.c (display_line): When hscrolling only the current
line, increment iterator's first_visible_x and last_visible_x
values to account for the hscroll. This propagates the hscroll
effect on the iterator geometry all the way down to the
subroutines called by display_line, and avoids scrolling bugs
under large hscroll values. (Bug#26994)
* src/data.c (ash_lsh_impl): Verify that signed right shift is
arithmetic; if we run across a compiler that uses a logical shift
we’ll need to complicate the code before removing this
compile-time check. Help the compiler do common subexpression
elimination better.
Problem reported by YAMAMOTO Mitsuharu in:
http://lists.gnu.org/archive/html/emacs-devel/2017-05/msg00342.html
This is related to the fix for Bug#26397.
* src/callproc.c (call_process_cleanup, call_process) [!MSDOS]:
Report internal error if wait_for_termination fails.
* src/sysdep.c (get_child_status): Return -1 if waitpid is
buggy, instead of aborting.
(wait_for_termination): Return bool success value.
All callers changed.
* src/emacs-module.c (MODULE_SETJMP_1): Use the local var
instead of leaving it unused, to pacify picky compilers.
(module_reset_handlerlist): Now takes a dummy pointer to a struct
handler *, instead of a dummy pointer to an int. All uses changed.
* src/xdisp.c (hscrolling_current_line_p): New function.
(init_iterator): If auto-hscrolling just the current line, don't
increment the iterator's first_visible_x and last_visible_x
variables.
(hscroll_window_tree): Recompute window's hscroll when moving
vertically to another screen line.
(redisplay_window): If we are hscrolling only the current line,
disable the optimizations that rely on the current matrix being
up-to-date.
(display_line): Accept an additional argument CURSOR_VPOS, the
vertical position of the current screen line which might need
hscrolling; all callers changed. Compute first_visible_x and
last_visible_x specially when auto-hscrolling current line, by
repeating the calculation that is done in init_iterator in other
modes.
(syms_of_xdisp) <auto-hscroll-mode>: No longer boolean, it can now
accept a 3rd value 'current-line, to turn on the mode where
only the current line is hscrolled.
* etc/NEWS: Mention the new auto-hscroll-mode value.

* src/conf_post.h (ATTRIBUTE_MAY_ALIAS, DECLARE_POINTER_ALIAS):
New macros.
* src/process.c (conv_sockaddr_to_lisp, conv_lisp_to_sockaddr)
(connect_network_socket, network_interface_info)
(server_accept_connection): Use it when aliasing non-char objects.
Problem reported by Jim Meyering in:
http://lists.gnu.org/archive/html/emacs-devel/2017-05/msg00246.html
* src/conf_post.h (vfork) [ADDRESS_SANITIZER]: Define to fork.
Unfortunately with the AddressSanitizer in Fedora 25 x86-64, the
vforked child messes up the parent’s shadow memory. This is too
bad, as we’d rather have AddressSanitizer catch memory-access bugs
related to vfork.
* src/process.c (connect_network_socket): Use verify,
not eassert, so that any problems are caught at compile-time.
Avoid dodgy cast by using a local var of the correct type.
* src/process.c (connect_network_socket) [HAVE_GETSOCKNAME]:
Remove redundant type-casting and variables. Don't call
'getsockname' to find the port for AF_LOCAL sockets.
[AF_INET6]: Add an assertion to verify that the ports in the IPv4
and IPv6 structures are at the same offset and have the same size.
