Jinoh Kang 7abca9742a gdiplus: Avoid copying GpImage's busy flag in select_frame_wic().
The 'busy' field in GpImage is used as an atomic variable.  The C11
standard (§5.1.2.4, paragraph 25) states that two conflicting actions to
a memory location shall be both atomic operations, or otherwise properly
synchronized; otherwise, it constitutes a data race.

However, select_frame_wic() performs a non-atomic access to the 'busy'
field on a GpImage that is potentially accessible by other threads.
This happens when select_frame_wic() copies new_image to the old image
object.  Although it does attempt to preserve the value of the 'busy'
field by setting new_image->busy = image->busy first, thereby
effectively assigning an identical value to the field, it is unclear
that this does not actually constitute a theoretical, if not practical,
data race.  This also prevents replacing the busy flag with a mutex or
other synchronization primitives.

Therefore, skip the 'busy' field when copying fields from the new image
to the original image object.

1. INTRODUCTION

Wine is a program which allows running Microsoft Windows programs
(including DOS, Windows 3.x, Win32, and Win64 executables) on Unix.
It consists of a program loader which loads and executes a Microsoft
Windows binary, and a library (called Winelib) that implements Windows
API calls using their Unix, X11 or Mac equivalents.  The library may also
be used for porting Windows code into native Unix executables.

Wine is free software, released under the GNU LGPL; see the file
LICENSE for the details.


2. QUICK START

From the top-level directory of the Wine source (which contains this file),
run:

./configure
make

Then either install Wine:

make install

Or run Wine directly from the build directory:

./wine notepad

Run programs as "wine program".  For more information and problem
resolution, read the rest of this file, the Wine man page, and
especially the wealth of information found at https://www.winehq.org.


3. REQUIREMENTS

To compile and run Wine, you must have one of the following:

  Linux version 2.0.36 or later
  FreeBSD 8.0 or later
  Solaris x86 9 or later
  NetBSD-current
  Mac OS X 10.8 or later

As Wine requires kernel-level thread support to run, only the operating
systems mentioned above are supported.  Other operating systems which
support kernel threads may be supported in the future.

FreeBSD info:
  Wine will generally not work properly on versions before FreeBSD 8.0.
  See https://wiki.freebsd.org/Wine for more information.

Solaris info:
  You will most likely need to build Wine with the GNU toolchain
  (gcc, gas, etc.). Warning : installing gas does *not* ensure that it
  will be used by gcc. Recompiling gcc after installing gas or
  symlinking cc, as and ld to the gnu tools is said to be necessary.

NetBSD info:
  Make sure you have the USER_LDT, SYSVSHM, SYSVSEM, and SYSVMSG options
  turned on in your kernel.

Mac OS X info:
  You need Xcode/Xcode Command Line Tools or Apple cctools.  The
  minimum requirements for compiling Wine are clang 3.8 with the
  MacOSX10.10.sdk and mingw-w64 v8.  The MacOSX10.14.sdk and later can
  only build wine64.


Supported file systems:
  Wine should run on most file systems. A few compatibility problems
  have also been reported using files accessed through Samba. Also,
  NTFS does not provide all the file system features needed by some
  applications.  Using a native Unix file system is recommended.

Basic requirements:
  You need to have the X11 development include files installed
  (called xorg-dev in Debian and libX11-devel in Red Hat).

  Of course you also need "make" (most likely GNU make).

  You also need flex version 2.5.33 or later and bison.

Optional support libraries:
  Configure will display notices when optional libraries are not found
  on your system. See https://wiki.winehq.org/Recommended_Packages for
  hints about the packages you should install. On 64-bit platforms,
  you have to make sure to install the 32-bit versions of these
  libraries.


4. COMPILATION

To build Wine, do:

./configure
make

This will build the program "wine" and numerous support libraries/binaries.
The program "wine" will load and run Windows executables.
The library "libwine" ("Winelib") can be used to compile and link
Windows source code under Unix.

To see compile configuration options, do ./configure --help.

For more information, see https://wiki.winehq.org/Building_Wine


5. SETUP

Once Wine has been built correctly, you can do "make install"; this
will install the wine executable and libraries, the Wine man page, and
other needed files.

Don't forget to uninstall any conflicting previous Wine installation
first.  Try either "dpkg -r wine" or "rpm -e wine" or "make uninstall"
before installing.

Once installed, you can run the "winecfg" configuration tool. See the
Support area at https://www.winehq.org/ for configuration hints.


6. RUNNING PROGRAMS

When invoking Wine, you may specify the entire path to the executable,
or a filename only.

For example: to run Notepad:

    wine notepad            (using the search Path as specified in
    wine notepad.exe         the registry to locate the file)

    wine c:\\windows\\notepad.exe      (using DOS filename syntax)

    wine ~/.wine/drive_c/windows/notepad.exe  (using Unix filename syntax)

    wine notepad.exe readme.txt          (calling program with parameters)

Wine is not perfect, so some programs may crash. If that happens you
will get a crash log that you should attach to your report when filing
a bug.
