* nt/inc/ms-w32.h (emacs_raise): New macro. * src/alloc.c (die): * src/sysdep.c (emacs_abort) [HAVE_NTGUI]: Avoid recursive loop if there's a fatal error in the function itself. * src/atimer.c (pending_atimers): * src/blockinput.h: Don't include "atimer.h"; no longer needed. (interrupt_input_pending): Remove. All uses removed. pending_signals now counts both atimers and ordinary interrupts. This is less racy than having three separate pending-signal flags. (block_input, unblock_input, totally_unblock_input, unblock_input_to) (input_blocked_p): Rename from their upper-case counterparts BLOCK_INPUT, UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO, INPUT_BLOCKED_P, and turn into functions. All uses changed. This makes it easier to access volatile variables more accurately. (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input (). (input_blocked_p): Prefer this to 'interrupt_input_blocked', as that's more reliable if the code is buggy and sets interrupt_input_blocked to a negative value. All uses changed. * src/atimer.c (deliver_alarm_signal): Remove. No need to deliver this to the parent; any thread can handle this signal now. All uses replaced by underlying handler. * src/atimer.c (turn_on_atimers): * src/dispnew.c (handle_window_change_signal): * src/emacs.c (handle_danger_signal): * src/keyboard.c (kbd_buffer_get_event): Don't reestablish signal handler; not needed with sigaction. * src/blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT) (UNBLOCK_INPUT_TO): Rework to avoid unnecessary accesses to volatile variables. (UNBLOCK_INPUT_TO): Now a function. (totally_unblock_input, unblock_input): New decls. * src/data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c (init_data): Remove. Necessary stuff now done in init_signal. * src/emacs.c, src/xdisp.c: Include "atimer.h", since we invoke atimer functions. * src/emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c. (fatal_error_code): Remove; no longer needed. (terminate_due_to_signal): Rename from fatal_error_backtrace, since it doesn't always backtrace. All uses changed. No need to reset signal to default, since sigaction and/or die does that for us now. Use emacs_raise (FOO), not kill (getpid (), FOO). (main): Check more-accurately whether we're dumping. Move fatal-error setup to sysdep.c * src/floatfns.c: Do not include "syssignal.h"; no longer needed. * src/gtkutil.c (xg_get_file_name, xg_get_font): Remove no-longer-needed signal-mask manipulation. * src/keyboard.c, src/process.c (POLL_FOR_INPUT): Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined. * src/keyboard.c (read_avail_input): Remove. All uses replaced by gobble_input. (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code. (kbd_buffer_store_event_hold, gobble_input): (record_asynch_buffer_change) [USABLE_SIGIO]: (store_user_signal_events): No need to mess with signal mask. (gobble_input): If blocking input and there are terminals, simply set pending_signals to 1 and return. All hooks changed to not worry about whether input is blocked. (process_pending_signals): Clear pending_signals before processing them, in case a signal comes in while we're processing. By convention callers now test pending_signals before calling us. (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input): New functions, to support changes to blockinput.h. (handle_input_available_signal): Now extern. (reinvoke_input_signal): Remove. All uses replaced by handle_async_input. (quit_count): Now volatile, since a signal handler uses it. (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg. All callers changed. Block SIGINT only if not already blocked. Clear sigmask reliably, even if Fsignal returns, which it can. Omit unnecessary accesses to volatile var. (quit_throw_to_read_char): No need to restore sigmask. * src/keyboard.c (gobble_input, handle_user_signal): * src/process.c (wait_reading_process_output): Call signal-handling code rather than killing ourselves. * src/lisp.h: Include <float.h>, for... (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication. (pending_signals): Now volatile. (syms_of_data): Now const if IEEE floating point. (handle_input_available_signal) [USABLE_SIGIO]: (terminate_due_to_signal, record_child_status_change): New decls. * src/process.c (create_process): Avoid disaster if memory is exhausted while we're processing a vfork, by tightening the critical section around the vfork. (send_process_frame, process_sent_to, handle_pipe_signal) (deliver_pipe_signal): Remove. No longer needed, as Emacs now ignores SIGPIPE. (send_process): No need for setjmp/longjmp any more, since the SIGPIPE stuff is now gone. Instead, report an error if errno is EPIPE. (record_child_status_change): Now extern. PID and W are now args. Return void, not bool. All callers changed. * src/sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]: Remove. All uses removed. This bug should be fixed now in a different way. (wait_for_termination_1): Use waitpid rather than sigsuspend, and record the child status change directly. This avoids the need to futz with the signal mask. (process_fatal_action): Move here from emacs.c. (emacs_sigaction_flags): New function, containing much of what used to be in emacs_sigaction_init. (emacs_sigaction_init): Use it. Block nonfatal system signals that are caught by emacs, to make races less likely. (deliver_process_signal): Rename from handle_on_main_thread. All uses changed. (BACKTRACE_LIMIT_MAX): Now at top level. (thread_backtrace_buffer, threadback_backtrace_pointers): New static vars. (deliver_thread_signal, deliver_fatal_thread_signal): New functions, for more-accurate delivery of thread-specific signals. (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c. (deliver_arith_signal): Handle in this thread, not in the main thread, since it's triggered by this thread. (maybe_fatal_sig): New function. (init_signals): New arg DUMPING so that we can be more accurate about whether we're dumping. Caller changed. Treat thread-specific signals differently from process-general signals. Block all signals while handling fatal error; that's safer. xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal on IEEE hosts. When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored. Ignore SIGPIPE unless batch. (emacs_backtrace): Output backtrace for the appropriate thread, which is not necessarily the main thread. * src/syssignal.h: Include <stdbool.h>. (emacs_raise): New macro. * src/xterm.c (x_connection_signal): Remove; no longer needed now that we use sigaction. (x_connection_closed): No need to mess with sigmask now. (x_initialize): No need to reset SIGPIPE handler here, since init_signals does this for us now. Fixes: debbugs:12471 |

Emacs for Windows NT/2000 and Windows 95/98/ME
Copyright (C) 2001-2012 Free Software Foundation, Inc.
See the end of the file for license conditions.
This directory contains support for compiling and running GNU Emacs on
Windows NT, Windows 95, and their successors. This port supports all
of the major functionality of the Unix version, including
subprocesses, windowing features (fonts, colors, scroll bars, multiple
frames, etc.), and networking support.
Precompiled distributions are also available; ftp to
ftp://ftp.gnu.org/gnu/emacs/windows/
for the latest precompiled distributions.
* Building and installing
See the INSTALL file in this directory for detailed instructions on
building and installing Emacs on your system.
* EXE files produced
Building and installing Emacs will produce the following executable
files in the bin directory.
+ emacs.exe - The main Emacs executable. As this is designed to run
as both a text-mode application (emacs -nw) and as a GUI application,
it will pop up a command prompt window if run directly from Explorer.
+ runemacs.exe - A wrapper for running Emacs as a GUI application
without popping up a command prompt window.
+ emacsclient.exe - A command-line client program that can
communicate with a running Emacs process. See the `Emacs Server'
node of the Emacs manual.
+ emacsclientw.exe - A version of emacsclient that does not open
a command-line window.
+ addpm.exe - A basic installer that creates Start Menu icons for Emacs.
Running this is optional.
+ cmdproxy.exe - Used internally by Emacs to work around problems with
the native shells in various versions of Windows.
+ ctags.exe, etags.exe - Tools for generating tag files. See the
`Tags' node of the Emacs manual.
+ ebrowse.exe - A tool for generating C++ browse information. See the
`Ebrowse' manual.
+ ddeclient.exe - A tool for interacting with DDE servers.
+ hexl.exe - A tool for converting files to hex dumps. See the
`Editing Binary Files' node of the Emacs manual.
+ movemail.exe - A helper application for safely moving mail from
a mail spool or POP server to a local user mailbox. See the
`Movemail' node of the Emacs manual.
* Further information
There is a web page that serves as a FAQ for the Windows port of
Emacs (a.k.a. NTEmacs) at:
http://www.gnu.org/software/emacs/windows/ntemacs.html
There is also a mailing list for discussing issues related to this
port of Emacs. For information about the list, see this Web page:
http://mail.gnu.org/mailman/listinfo/help-emacs-windows
To ask questions on the mailing list, send email to
help-emacs-windows@gnu.org. (You don't need to subscribe for that.)
To subscribe to the list or unsubscribe from it, fill the form you
find at http://mail.gnu.org/mailman/listinfo/help-emacs-windows as
explained there.
Another valuable source of information and help which should not be
overlooked is the various Usenet news groups dedicated to Emacs.
These are particularly good for help with general issues which aren't
specific to the Windows port of Emacs. The main news groups to use
for seeking help are:
gnu.emacs.help
comp.emacs
There are also fairly regular postings and announcements of new or
updated Emacs packages on this group:
gnu.emacs.sources
* Reporting bugs
If you encounter a bug in this port of Emacs, we would like to hear
about it. First check the file etc/PROBLEMS and the FAQ on the web
page above to see if the bug is already known and if there are any
workarounds. If not, then check whether the bug has something to do
with code in your .emacs file, e.g. by invoking Emacs with the "-Q"
option.
Use the built in bug reporting functionality in Emacs so that it
will be seen by the right people. You can use the command M-x
report-emacs-bug to create and send the bug report, but in some
cases there is a function to report bugs in a specific package;
e.g. M-x gnus-bug for Gnus, M-x c-submit-bug-report for C/C++/Java
mode, etc.
