Implement Freeze() by blocking the GtkWindow "expose-event"/"draw" signal
instead. Since the introduction of client-side windows in GTK+ 2.18,
gdk_window_freeze_updates() is unuseable because the impl_window (and thus the
update_freeze_count) for a given GdkWindow can change unpredictably. See #16795
This should prevent an assert failure which happens if we call Accept() on an
invalid server below and also confirm if the server creation really failed or
not.
Its value (0x80000000) is outside of the int type range on 32 bit platforms,
but we still want to allow using it as an initializer of int and/or long
variables for consistency with the other types, so cast it to int explicitly
to suppress -Wnarrowing warnings from recent g++ which were given when doing
this before.
Recent g++ versions give -Wnarrowing warning when a value outside of the type
range is used to initialize a variable of this type in { }. Avoid it in the
long long tests using explicit casts as we already cast between long long and
unsigned long long values here anyhow.
g++ 4.8.2, shipped with Ubuntu 14.04, generates incorrect code for checking
the loop termination condition, resulting in never ending loops in
HashMapTest().
Disable the optimizations for this function for 4.8.[012] as the bug seems to
be fixed in 4.8.4 and several similar (but not really identical) bug reports
in gcc bugzilla have been fixed in 4.8.3.
This should allow the unit tests on Linux buildbots, using 4.8.2, to run to
completion again.
Valgrind complains about reading beyond the end of buffer when using glibc
std::string for wxString implementation under amd64 Linux. Don't suppose that
the buffer has one extra null word at its end to avoid this.
Allow a library and an application to differ in __GXX_ABI_VERSION
within the range 1002-1008. The ABI changes made in this range
do not affect wxWidgets.
Calling SetMinSize() on wxMDIChildFrame in wxMSW prevented SetMaxSize() from
working as wxMDIChildFrame::HandleGetMinMaxInfo() didn't take the max size
into account and prevented the execution of the base class version of the same
method from taking place if min size was set.
Fix this simply by always delegating to the base class version after using
DefMDIChildProc() to compute the default max size values.
Closes#17029.
Declare _hypot() function globally, predefining __NO_INLINE__ in wx/math.h is
not enough as <math.h> is also included from some other standard headers, e.g.
<algorithm>, and including them results in the same bug as in wx/math.h
(i.e. https://sourceforge.net/p/mingw/bugs/2250/).
Definitions of non-standard LLONG_MAX, LLONG_MIN and ULLONG_MAX constants are
excluded from MinGW limits.h when compiling in "strict ANSI" mode, so define
them ourselves.
Don't ignore errors (this resulted in warnings in optimized builds because
variable "hr" containing the error code to was assigned but never used) and
don't leak memory in the (admittedly unlikely) case an error really occurs.
Also don't duplicate the code for creating a one element SAFEARRAY<VARIANT>,
extract it into a helper function.
Don't cast NMHDR::code field to int, this cast was added in the previous
millennium, probably to work around the wrong definition of NM_DBLCLK in some
ancient MinGW headers, but nowadays all MinGW distributions (tested with
MinGW 4.8.1, MinGW-64 4.9.1 and TDM-GCC 4.9.2) define it correctly and so
using this cast results in a warning -- just remove it to get rid of it.
Including standard math.h header with both -O2 and -std=c++NN options results
in compilation error due to a bug in the header, see MinGW bug report at
https://sourceforge.net/p/mingw/bugs/2250/
Work around this to allow the library to compile in release build with
-std=c++11. This is ugly but better than failing to compile at all.
