* src/xdisp.c (redisplay_internal): When retrying redisplay of a
frame because new fonts were loaded, disable all redisplay
optimizations on that frame by calling SET_FRAME_GARBAGED.
(Bug#20410)
Don't freeze if an exiting process can't be read from. (Bug#19860).
This fixes a bug I introduced in
2014-07-08T07:24:07Z@eggert@cs.ucla.edu
"* process.c: Add sanity checks for file descriptors."
Dmitry Gutov did most of the legwork in finding the problem.
* src/process.c (wait_reading_process_output):
Treat non-running processes that can't be read from
the same as other non-running processes.
* src/print.c: Include <c-ctype.h>, for c_isxdigit.
(print_object): When print-escape-multibyte is non-nil and a
multibyte character is followed by a newline or formfeed, followed
by a hex digit, don't output a needless "\ " before the hex digit.
* test/automated/print-tests.el (print-hex-backslash): New test.
* src/xdisp.c (syms_of_xdisp): Define a boolean `inhibit_message'.
(message3): Don't call `message3_nolog' (i.e. use the Echo Area) when
`inhibit_message' is non-zero.
* etc/NEWS: Add an entry.
* doc/lispref/display.texi: Add an entry for `inhibit-message',
mention it in `message'.
* src/print.c (PRINTDECLARE): Remove. Move its contents into
PRINTPREPARE; doable now that we assume C99. All callers changed.
(PRINTCHAR): Remove, as it adds more mystery than clarity.
All callers changed.
(strout): Assume that caller computes length. All callers changed.
(print_c_string): New function.
(write_string, write_string_1): Compute length instead of asking
the caller to compute it. All callers changed.
(write_string): Simplify by using write_string_1.
(write_string_1): Simplify by using print_c_string.
(Fterpri): Compute default val more clearly.
(Fprin1_to_string, print_object):
Assume C99 to avoid unnecessary nesting.
(print_object): Prefer print_c_string to multiple printchar, or
to calling strout with -1 length. Coalesce into sprintf when
this is easy.
* doc/lispref/searching.texi (Char Classes):
* lisp/emacs-lisp/rx.el (rx): Document [:graph:] to be [:print:]
sans whitespace (not sans space).
* src/character.c (graphicp): Exclude all Unicode whitespace chars,
not just space.
* src/regex.c (ISGRAPH): Exclude U+00A0 (NO-BREAK SPACE).
In POSIX [[:print:]] is equivalent to [ [:graph:]], so change
[:graph:] so that it matches everything that [:print:] does,
except for space.
* doc/lispref/searching.texi (Char Classes):
* etc/NEWS:
* lisp/emacs-lisp/rx.el (rx):
Document [:graph:] to be [:print:] sans ' '.
* src/character.c, src/character.h (graphicp): New function.
* src/regex.c (ISGRAPH) [emacs]: Use it.
(BIT_GRAPH): New macro.
(BIT_PRINT): Increase to 0x200, to make room for BIT_GRAPH.
(re_wctype_to_bit) [! WIDE_CHAR_SUPPORT]:
Return BIT_GRAPH for RECC_GRAPH.
(re_match_2_internal) [emacs]: Use ISGRAPH if BIT_GRAPH,
and ISPRINT if BIT_PRINT.
* src/regex.c (ISPRINT): Call 'printablep' for multibyte characters.
(BIT_PRINT): New bit mask.
(re_wctype_to_bit): Return BIT_PRINT for RECC_PRINT.
* src/character.c (printablep): New function.
* src/character.h (printablep): Add prototype.
* lisp/emacs-lisp/rx.el (rx): Doc fix: document the new behavior
of 'print', 'alnum', and 'alphabetic'.
* doc/lispref/searching.texi (Char Classes): Document the new
behavior of [:print:].
* etc/NEWS: Mention the new behavior of [:print:].
* src/print.c (print_object):
* src/window.c (sequence_number):
* src/window.h (struct window.sequence_number):
Don't assume window sequence number fits in int.
* src/window.c (window_select_count):
* src/window.h (struct window.use_time, window_select_count):
Don't assume window use time fits in int.
* src/window.c (Fsplit_window_internal):
Don't assume user-supplied integer, or sum, fits in int.
(Fset_window_configuration, count_windows, get_leaf_windows)
(save_window_save, Fcurrent_window_configuration):
Use ptrdiff_t for object counts.
(Fset_window_configuration): Omit unused local 'n'.
(count_windows): Simplify by writing in terms of get_leaf_windows.
(get_leaf_windows): Don't store through FLAT if it's null.
(extract_dimension): New static function.
(set_window_margins, set_window_fringes, set_window_scroll_bars):
Use it to avoid undefined behavior when converting user-supplied
integer to 'int'.
* src/cmds.c (remove_excessive_undo_boundaries): New function,
extracted from Fself_insert_command.
(Fdelete_char, Fself_insert_command): Use it.
* src/fileio.c (Fmake_symbolic_link): Rename arg to `target'.
* src/keyboard.c (syms_of_keyboard): `top-level' shouldn't be special.
* src/gnutls.c (syms_of_gnutls) <libgnutls-version>: New DEFSYM.
* lisp/term/w32-win.el (dynamic-library-alist): Determine which
GnuTLS DLL to load according to value of libgnutls-version.
Fixes: bug#20294
Copyright-paperwork-exempt: yes
* src/w32.h (register_aux_fd): New function declaration.
* src/w32.c (register_aux_fd): New function.
* src/process.h (struct Lisp_Process): New member stderrproc.
* src/process.c (PIPECONN_P): New macro.
(PIPECONN1_P): New macro.
(Fdelete_process, Fprocess_status, Fset_process_buffer)
(Fset_process_filter, Fset_process_sentinel, Fstop_process)
(Fcontinue_process): Handle pipe process specially.
(create_process): Respect p->stderrproc.
(Fmake_pipe_process): New function.
(Fmake_process): Add new keyword argument :stderr.
(wait_reading_process_output): Specially handle a pipe process when
it gets an EOF.
(syms_of_process): Register Qpipe and Smake_pipe_process.
* doc/lispref/processes.texi (Asynchronous Processes): Document
`make-pipe-process' and `:stderr' keyword of `make-process'.
* lisp/subr.el (start-process): Suggest to use `make-process' handle
standard error separately.
* test/automated/process-tests.el (process-test-stderr-buffer)
(process-test-stderr-filter): New tests.
* etc/NEWS: Mention new process type `pipe' and its usage with the
`:stderr' keyword of `make-process'.
* src/window.c (Frecenter): Use the same code for GUI and TTY
frames alike; use vmotion only for "initial" frames. This is
because vmotion doesn't support visual-line-mode. Rewrite the
'iarg >= 0' case to use move_it_* functions instead of using
vmotion, for the same reason. Fix the clipping of the argument
value to support scroll-margin in all cases and avoid unwarranted
recentering. Reported by Milan Stanojević <milanst@gmail.com> in

Derived from a bug report by Nicolas Richard in:
http://bugs.gnu.org/20191#20
* xsmfns.c (smc_save_yourself_CB): Don't dump core if
invocation-name is not a string. Initialize user-login-name if it
is not already initialized, and don't dump core if it is not a
string.
(create_client_leader_window): Don't dump core if x-resource-name
and x-resource-class are not both strings.
(x_session_initialize): Don't dump core if x-session-previous-id,
invocation-directory, and invocation-name are not strings.
* editfns.c (Fuser_login_name, Fuser_real_login_name)
(syms_of_editfns): Don't rely on all-bits-zero being an Elisp integer,
as this is no longer true now that Qnil == 0.
From a suggestion by Eli Zaretskii in:
http://lists.gnu.org/archive/html/emacs-devel/2015-03/msg00824.html
* process.c (NON_BLOCKING_CONNECT): Simplify by assuming that
BROKEN_NON_BLOCKING_CONNECT is not defined.
(SELECT_CAN_DO_WRITE_MASK): Remove, and assume it's now true.
