Thierry Reding [Wed, 19 Feb 2014 16:16:48 +0000 (17:16 +0100)]
test/input: Fix alignment assertion for doubles

The code previously tried to compute the offset of a field in the
valuator by subtracting the address of the valuator from the _value_ of
the field (rather than the field's address). The correct way to do it
would have been (note the &'s):

assert(((void *) &v->axisVal - (void *) v) % sizeof(double) == 0);
assert(((void *) &v->axes - (void *) v) % sizeof(double) == 0);

That's essentially what the offsetof() macro does. Using offsetof() has
the added benefit of not using void pointer arithmetic and therefore
silencing a warning on some compilers.

10 years agoxfree86: Keep a non-seat0 X server from touching VTs (#71258)
Laércio de Sousa [Thu, 12 Dec 2013 16:22:48 +0000 (14:22 -0200)]
xfree86: Keep a non-seat0 X server from touching VTs (#71258)

Updated patch following Hans de Goede's advice.

If -seat option is passed with a value different from seat0,
X server won't call xf86OpenConsole().

This is needed to avoid any race condition between seat0 and
non-seat0 X servers. If a non-seat0 X server opens a given VT
before a seat0 one which expects to open the same VT, one can
get an inactive systemd-logind graphical session for seat0.

This patch was first tested in a multiseat setup with multiple
video cards and works quite well.

I suppose it can also make things like DontVTSwitch and -sharevts
meaningless for non-seat0 seats, so it may fix bug #69477, too.

Add 'FONT_PATH_NAME_ELEMENT_CONST' to dix-config.h and xorg-server.h

This signals to the fontsproto code that the X server has been fixed
to allow the name member in a FontPathElement struct to be declared
const to eliminate piles of warnings when assigning string constants
to them.

Ignore a couple of format-nonliteral warnings

These are generated in code which uses sprintf as a convenient way to
construct strings from various pieces.

10 years agoIf EAGAIN == EWOULDBLOCK, only need to check errno for one of them
Alan Coopersmith [Sat, 4 Jan 2014 08:09:45 +0000 (00:09 -0800)]
If EAGAIN == EWOULDBLOCK, only need to check errno for one of them

Solaris <sys/errno.h> has:
 #define EWOULDBLOCK       EAGAIN
so checking (errno == EAGAIN || errno == EWOULDBLOCK) is overkill.

This leads cppcheck 1.62 to complain:
[xserver/os/io.c:365] -> [xserver/os/io.c:365]: (style) Same expression on both sides of '||'.
[xserver/os/io.c:941] -> [xserver/os/io.c:941]: (style) Same expression on both sides of '||'.

This quiets it, and reduces the number of calls Solaris Studio cc
generates to the __errno() function to get the thread-specific errno value.
