Subject: Fix locking in _XimGetWindowEventmask.
X-Git-Url: http://gitweb.freedesktop.org/?p=xorg/lib/libX11.git;a=commitdiff;h=c2f88cdf5cd9c94b77e5bfdac572b5ac06ab4aa8
Fix locking in _XimGetWindowEventmask.
Now that XFilterEvent drops the Display lock before invoking callback
functions, _XimGetWindowEventmask is called without the lock held. So
when it called _XGetWindowAttributes, a variant of XGetWindowAttributes
that does not lock the Display, Xlib/XCB would assert:
xcb_xlib.c:50: xcb_xlib_unlock: Assertion `c->xlib.lock' failed.
Should fix Gentoo #156367, Ubuntu #87947, Debian #427296. And others?
