* src/callproc.c (get_current_directory): Rename from
'encode_current_directory' and add boolean ENCODE flag.
(Fcall_process): Interpret INFILE relative to the working directory
from which PROGRAM is run, not 'default-directory'.
(call_process): Use 'get_current_directory'.
* src/process.c (Fmake_process): Use 'get_current_directory'.
* src/process.h (get_current_directory): Rename decl from
'encode_current_directory'.
* src/sysdep.c (sys_subshell): Use 'get_current_directory' (bug#49283).
* src/process.c (add_non_keyboard_read_fd): Make this a public function.
(add_process_read_fd): Fold old, static add_non_keyboard_read_fd guts
into here.
* src/xsmfns.c (ice_conn_watch_CB): Call add_non_keyboard_read_fd
(bug#43834).
A common complaint about the module API is that modules can't
communicate asynchronously with Emacs. While it isn't possible to
call arbitrary Emacs functions asynchronously, writing to a pipe
should always be fine and is a pretty low-hanging fruit.
This patch implements a function that adapts an existing pipe
process. That way, users can use familiar tools like process filters
or 'accept-process-output'.
* src/module-env-28.h: Add 'open_channel' module function.
* src/emacs-module.c (module_open_channel): Provide definition for
'open_channel'.

Solution suggested by Stefan Monnier in:
https://lists.gnu.org/r/emacs-devel/2019-04/msg00282.html
* src/buffer.h (BUFFER_LISP_SIZE): Simplify by using PSEUDOVECSIZE.
(BUFFER_REST_SIZE): Simplify by using VECSIZE and BUFFER_LISP_SIZE.
* src/lisp.h (PSEUDOVECSIZE): Base it on the last Lisp field,
not the first non-Lisp field. All callers changed. Callers
without Lisp fields changed to use ALLOCATE_PLAIN_PSEUDOVECTOR.
(ALLOCATE_PLAIN_PSEUDOVECTOR): New macro.
* src/process.c (dissociate_controlling_tty): New function.
(create_process): Use it to dissociate controlling tty if setsid
fails, which happens on Darwin after a vfork (Bug#33154).
Do this on all platforms, not just on Darwin, as a similar
problem is plausible elsewhere.
* src/callproc.c (call_process): Use the new function here, too,
for consistency and to avoid duplicate code.
sizeof (struct Lisp_Marker) was 32 on x86, where 24 would do.

* src/xterm.h (struct scroll_bar):
* src/xwidget.h (struct xwidget, struct xwidget_view):
Add GCALIGNED_STRUCT attribute.
* src/lisp.h (GCALIGNED_UNION_MEMBER): Renamed from GCALIGNED_UNION.
All uses changed.
(GCALIGNED_STRUCT_MEMBER, GCALIGNED_STRUCT, GCALIGNED): New macros.
All uses of open-coded GCALIGNED changed to use GCALIGNED.
(union vectorlike_header): No longer GC-aligned.
(PSEUDOVECSIZE): Yield 0 for pseudovectors without Lisp
objects that place a member before where the first Lisp object
member would be.
* src/gnutls.c (gnutls_deinit_certificates): New function.
(Fgnutls_peer_status): Return all certificates in the chain back
to Lisp land.
(gnutls_verify_boot): Compute all the x509 certificates in the
chain.
* src/process.h (struct Lisp_Process): Adjust gnutls fields so
that we can keep tracks of all certificates in the chain instead
of just the host certificate.
Instead of using __builtin_assume_aligned (P, GCALIGNMENT) to
tell GCC that P has alignment 8, use (T *) P where T is the
type of the pointed-to object, to tell GCC that P has native
alignment. This is simpler, matches the intent better, and
should help simplify future improvements. Some of these
changes are to pacify gcc -Wnull-dereference, since GCC is
smarter about pointers now that Emacs no longer uses
__builtin_assume_aligned; these minor changes should improve
code efficiency slightly. On Fedora 28 x86-64 with default
optimization this patch shrinks the size of the Emacs text
segment by 0.36%.
* src/conf_post.h (__has_builtin, __builtin_assume_aligned):
Remove; no longer used.
* src/dbusbind.c (XD_OBJECT_TO_DBUS_TYPE):
Pacify -Wnull-dereference by using XCAR instead of CAR_SAFE
and XCDR instead of CDR_SAFE when this is safe.
* src/fileio.c (Fexpand_file_name):
* src/font.c (clear_font_cache):
Pacify -Wnull-dereference by removing unnecessary NILP test.
* src/keyboard.c (xevent_start): New function.
(read_char, read_key_sequence): Pacify -Wnull-dereference by
using xevent_start instead of EVENT_START.
* src/lisp.h (lisp_h_XUNTAG): Remove; XUNTAG is always a macro
now, since it can no longer be implemented as a function.
(XUNTAG): New third argument CTYPE. All uses changed.
Cast result to CTYPE * instead of using __builtin_assume_aligned.
Simplify by using LISP_WORD_TAG.
(LISP_WORD_TAG): New macro.
(TAG_PTR): Use it.
* src/menu.c (x_popup_menu_1):
Pacify -Wnull-dereference by using XCAR instead of Fcar and
XCDR instead of Fcdr where this is safe.
* src/process.c (read_process_output): Track bytes read from
a process.
(wait_reading_process_output): If called recursively through
timers and/or process filters via accept-process-output, it is
possible that the output of wait_proc has already been read by
one of those recursive calls, leaving the original call hanging
forever if no further output arrives through that fd and no
timeout has been set. Fix that by using the process read
accounting to keep track of how many bytes have been read and
use that as a condition to break out of the infinite loop and
return to the caller as well as to calculate the proper return
value (if a wait_proc is given that is).
* src/process.h (struct Lisp_Process): Add nbytes_read to track
bytes read from a process.
(cherry picked from commit 4ba32858d6)
* src/process.c (read_process_output): Track bytes read from
a process.
(wait_reading_process_output): If called recursively through
timers and/or process filters via accept-process-output, it is
possible that the output of wait_proc has already been read by
one of those recursive calls, leaving the original call hanging

* src/process.h (struct Lisp_Process): Add nbytes_read to track
bytes read from a process.
* src/lisp.h (vectorlike_headed): Change from struct to union.
All uses changed. Since it has only one member, this does not
change semantics. This is designed to simplify future changes
needed to fix bugs like Bug#29040. All uses changed.
Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
This puts basic functions for types to be after the corresponding
type definitions. This is a more-common programming style in C,
and will make it easier to port Emacs to gcc
-fcheck-pointer-bounds, since the functions now have access to the
corresponding types' sizes. This patch does not change the code;
it just moves declarations and definitions and removes
no-longer-needed forward declarations (Bug#25128).
* src/buffer.c, src/data.c, src/image.c:
Include process.h, for PROCESSP.
* src/buffer.h (BUFFERP, CHECK_BUFFER, XBUFFER):
* src/process.h (PROCESSP, CHECK_PROCESS, XPROCESS):
* src/termhooks.h (TERMINALP, XTERMINAL):
* src/window.h (WINDOWP, CHECK_WINDOW, XWINDOW):
* src/thread.h (THREADP, CHECK_THREAD, XTHREAD, MUTEXP, CHECK_MUTEX)
(XMUTEX, CONDVARP, CHECK_CONDVAR, XCONDVAR):
Move here from lisp.h.
* src/intervals.h: Include buffer.h, for BUFFERP.
Include lisp.h, for Lisp_Object.
* src/lisp.h: Reorder declarations and definitions as described
above. Move thread includes to be later, so that they can use the
reordered definitions. Move some symbols to other headers (noted
elsewhere). Remove forward decls that are no longer needed.
* src/thread.h: Include systhread.h here, not in lisp.h,
since lisp.h itself does not need systhread.h.
Problem reported by Philipp Stephani (Bug#24869).
* src/callproc.c (child_setup) [!DOS_NT]:
Call restore_nofile_limit in the child.
* src/process.c (nofile_limit) [HAVE_SETRLIMIT]: New static var.
(restore_nofile_limit): New function.
(init_process_emacs) [HAVE_SETRLIMIT]: Set the new var.
This problem was introduced by the recent async changes (Bug#23808).
* src/process.c (Fmake_process): Move USE_SAFE_ALLOCA later,
so that it follows the start_process_unwind unwind-protect.
Set pid to -1 while the process is being created.
(start_process_unwind): Omit unnecessary emacs_abort test.
(connect_network_socket): Simplify use of counts. Unwind
bind_polling_period a bit earlier, so that a remove_process
unwind-protect can be added when needed; this is the heart of
the fix. Undo the unwind-protect just before returning.

Patch from a suggestion by Andreas Schwab in:
http://bugs.gnu.org/17976#39
This patch is for non-MS-Windows platforms.
I don't know the situation on MS-Windows.
* src/process.c (connecting_status):
New function, for (connect . ADDRINFOS).
(connect_network_socket, check_for_dns, wait_for_socket_fds)
(wait_while_connecting, wait_reading_process_output, status_notify):
Use it.
(decode_status, Fmake_network_process):
Support (connect . ADDRINFOS) status.
(connect_network_socket) [!WINDOWSNT]:
If the connection failed and there are other addresses to try, do not
signal an error; instead, loop around to try the next address.
(wait_reading_process_output): Advance to the next address
if there are multiple addresses and the first remaining address
failed.
* src/process.h (struct Lisp_Process.status): Adjust comment
to describe (connect . ADDRINFOS).
* src/process.c (decode_status): 3rd arg is now Lisp_Object *,
not int *, and is not decoded. All uses changed.
(status_message): Do not assume ‘failed’ code is an integer.
* src/process.h: Document codes better.
Problem reported by Ken Brown in:
http://lists.gnu.org/archive/html/emacs-devel/2016-05/msg00483.html
* src/process.c (conv_addrinfo_to_lisp): New function.
(connect_network_socket): Arg is now a list of addrinfos, not
merely IP addresses. All uses changed. Use protocol from
each addrinfo.
(Fmake_network_process): Accumulate protocols into addrinfos
rather than just using the last one found.
(check_for_dns): Accumulate protocols here, too.
* src/process.h (struct Lisp_Process): Remove ai_protocol;
no longer needed.

* lisp/net/gnutls.el (gnutls-negotiate): Make negotiation blocking.
* src/gnutls.c (Fgnutls_boot): Provide a new keyword,
:complete-negotiation, to specify that we want complete
negotiation even if the socket is non-blocking.
(gnutls_try_handshake): Complete negotiation if given that keyword.
* src/process.h (L): Added gnutls_complete_negotiation_p.
* src/process.c (struct sockaddr_and_len, conv_sockaddr_to_lisp)
(get_lisp_to_sockaddr_size, Fset_process_datagram_address)
(connect_network_socket):
Use ptrdiff_t, not int, for signed object sizes.
This addresses only a theoretical problem, as in practice these
object sizes are less than 2**31, but we might as well use the
same style here as elsewhere in Emacs.
(string_integer_p): Remove; all uses removed.
(Fmake_network_process): Check that port number is in range.
When converting an integer-string service, rely on strtol
rather than rechecking the string by hand.

Adjust prototypes to match.
* src/frame.h (FRAME_WINDOW_CONFIGURATION_CHANGED):
Omit unnecessary parens.

(wait_for_socket_fds): 2nd arg is now const ptr.
* src/process.h (struct Lisp_Process.dns_request):
Now struct gaicb *, not struct gaicb **, since there was always
exactly one. All uses changed.
* src/window.c, src/window.h (run_window_configuration_change_hook):
Now static.
* gnutls.c (boot_error): New function to either signal an
error or return an error code.
(Fgnutls_boot): Don't signal errors when running asynchronously.
* process.h (pset_status): Move here from process.c to be
able to use from gnutls.c.
* process.c (connect_network_socket): Do the TLS boot here
when running asynchronously.
(wait_reading_process_output): Rework the dns_processes
handling for more safety.
* lisp/net/gnutls.el (open-gnutls-stream): Compute the
gnutls-boot parameters and pass them to the process object.
(gnutls-negotiate): New parameter :return-keywords that won't
connect to anything, just compute the keywords.
* lisp/url/url-http.el (url-http): Revert async TLS sentinel
hack, which is no longer necessary.
* src/gnutls.c (Fgnutls_asynchronous_parameters): Rename from
gnutls-mark-process.

the nowait parameter.

sentinel created by open-gnutls-stream.

* src/process.c (send_process): Don't write to GnuTLS sockets that
haven't been initialised yed.
* src/process.h: New slot gnutls_wait_p.
* process.c (Fmake_network_process): Do asynchronous DNS
lookups if we have getaddrinfo_a and the user requests :nowait.
(check_for_dns): New function.
(wait_reading_process_output): Check for pending name
resolution in the idle loop.
* process.h: Add structure for async DNS.
* src/process.c (set_network_socket_coding_system)
(connect_network_socket): Refactor out of
make_network_process to allow calling connect_network_socket
asynchronously.
(Fmake_network_process): Do nothing but parsing the parameters
and name resolution, leaving the connection to
connect_network_socket.
Redo src/*.h so that each include file is idempotent (that is, can
be included multiple times with the latter inclusions having no
effect) and standalone (that is, can be included by itself,
with no include file other than config.h needed as a prerequisite).
This is standard practice in GNU programs nowadays.

* dispextern (struct image_type):
* font.c (font_property_table):
* frame.c (struct frame_parm_table, frame_parms):
* keyboard.c (scroll_bar_parts, struct event_head):
* xdisp.c (struct props):
Use XSYMBOL_INIT (Qfoo) and struct Lisp_Symbol * rather than &Qfoo and
Lisp_Object *, since Qfoo is no longer an object whose address can be
taken. All uses changed.
* eval.c (run_hook): New function. Most uses of Frun_hooks changed to
use it, so that they no longer need to take the address of a Lisp sym.
(syms_of_eval): Don't use DEFSYM on Vrun_hooks, as it's a variable.
* frame.c (syms_of_frame): Add defsyms for the frame_parms table.
* keyboard.c (syms_of_keyboard): Don't DEFSYM Qmenu_bar here.
DEFSYM Qdeactivate_mark before the corresponding var.
* keymap.c (syms_of_keymap): Use DEFSYM for Qmenu_bar and Qmode_line
instead of interning their symbols; this avoids duplicates.
(LISP_INITIALLY, TAG_PTR)
(DEFINE_LISP_SYMBOL_BEGIN, DEFINE_LISP_SYMBOL_END, XSYMBOL_INIT):
New macros.
(LISP_INITIALLY_ZERO): Use it.
(enum symbol_interned, enum symbol_redirect, struct Lisp_Symbol)
(EXFUN, DEFUN_ARGS_MANY, DEFUN_ARGS_UNEVALLED, DEFUN_ARGS_*):
Move decls up, to avoid forward uses. Include globals.h earlier, too.
(make_lisp_symbol): New function.
(XSETSYMBOL): Use it.
(DEFSYM): Now just a placeholder for make-docfile.
* lread.c (DEFINE_SYMBOLS): Define, for globals.h.
(intern_sym): New function, with body taken from old intern_driver.
(intern_driver): Use it. Last arg is now Lisp integer, not ptrdiff_t.
All uses changed.
(define_symbol): New function.
(init_obarray): Define the C symbols taken from lispsym.
Use plain DEFSYM for Qt and Qnil.
* syntax.c (init_syntax_once): No need to worry about
Qchar_table_extra_slots.
