* etc/NEWS: Document this. * nt/inc/unistd.h (O_NOFOLLOW): New macro. * src/filelock.c: Include <c-ctype.h>. (MAX_LFINFO): New top-level constant. (lock_info_type): Remove members pid, boot_time. Add members at, dot, colon. Change user member to be the entire buffer, not a pointer. This allows us to handle the case where a foreign pid or boot time exceeds the local range. All uses changed. (LINKS_MIGHT_NOT_WORK): New constant. (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing. (defined_WINDOWSNT): Remove. (MAKE_LOCK_NAME, file_in_lock_file_name): Always use .#FILE (not .#-FILE) for the file lock, even if it is a regular file. (rename_lock_file): New function. (create_lock_file): Use it. (create_lock_file, read_lock_data): Prefer a symbolic link for the lock file, falling back on a regular file if symlinks don't work. Do not try to create symlinks on MS-Windows, due to security hassles. Stick with POSIXish functions (open, read, write, close, fchmod, readlink, symlink, link, rename, unlink, mkstemp) when creating locks, as a GNUish host may be using a Windowsish file system, and cannot use MS-Windows-only system calls. Fall back on mktemp if mkstemp doesn't work. Don't fail merely because of a symlink-contents length limit in the current file system; fall back on regular files. Increase the symlink contents length limit to 8 KiB, this should be big enough for any real use and doesn't crunch the stack. (create_lock_file, lock_file_1, read_lock_data): Simplify allocation of lock file buffers now that they fit in 8 KiB. (lock_file_1): Return error number, not bool. All callers changed. (ELOOP): New macro, if not already defined. (read_lock_data): Return size of lock file contents, not Lisp object. All callers changed. Handle a race condition if some other process replaces a regular-file lock with a symlink lock or vice versa, while we're trying to read the lock. (current_lock_owner): Parse contents more carefully, to help avoid confusing a regular-file lock with some other application's use of the file. Check for lock file contents being too long, or not parsing correctly. (current_lock_owner, lock_file): Allow foreign pid and boot times that exceed the local range. (current_lock_owner, lock_if_free, lock_file): Simplify allocation of lock file contents. * src/w32.c (sys_rename_replace): New function, containing most of the contents of the old sys_rename. (sys_rename): Use it. (fchmod): New dummy function. * src/w32.h (sys_rename_replace, fchmod): New decls. Fixes: debbugs:13807 |

Emacs for Windows NT/2000 and Windows 95/98/ME
Copyright (C) 2001-2013 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.
