2013-02-23Replace all setjmp()/longjmp() with sigsetjmp()/siglongjmp()Peter Maydell9-42/+52
The setjmp() function doesn't specify whether signal masks are saved and restored; on Linux they are not, but on BSD (including MacOSX) they are. We want to have consistent behaviour across platforms, so we should always use "don't save/restore signal mask" (this is also generally going to be faster). This also works around a bug in MacOSX where the signal-restoration on longjmp() affects the signal mask for a completely different thread, not just the mask for the thread which did the longjmp. The most visible effect of this was that ctrl-C was ignored on MacOSX because the CPU thread did a longjmp which resulted in its signal mask being applied to every thread, so that all threads had SIGINT and SIGTERM blocked. The POSIX-sanctioned portable way to do a jump without affecting signal masks is to siglongjmp() to a sigjmp_buf which was created by calling sigsetjmp() with a zero savemask parameter, so change all uses of setjmp()/longjmp() accordingly. [Technically POSIX allows sigsetjmp(buf, 0) to save the signal mask; however the following siglongjmp() must not restore the signal mask, so the pair can be effectively considered as "sigjmp/longjmp which don't touch the mask".] For Windows we provide a trivial sigsetjmp/siglongjmp in terms of setjmp/longjmp -- this is OK because no user will ever pass a non-zero savemask. The setjmp() uses in tests/tcg/test-i386.c and tests/tcg/linux-test.c are left untouched because these are self-contained singlethreaded test programs intended to be run under QEMU's Linux emulation, so they have neither the portability nor the multithreading issues to deal with.

2013-02-23qemu-log: Remove qemu_log_try_set_file() and its usersPeter Maydell5-16/+0
Remove the function qemu_log_try_set_file() and its users (which are all in TCG code generation functions for various targets). This function was added to abstract out code which was originally written as "if (!logfile) logfile = stderr;" in order that BUG: case code which did an unguarded "fprintf(logfile, ...)" would not crash if debug logging was not enabled. Since those direct uses of logfile have also been abstracted away into qemu_log() calls which check for a NULL logfile, there is no need for the target-* files to mess with the user's chosen logging settings.

2013-02-21gtk: add support for screen scaling and full screen (v5)Anthony Liguori1-17/+237
Basic menu items to enter full screen mode and zoom in/out. Unlike SDL, we don't allow arbitrary scaling based on window resizing. The current behavior with SDL causes a lot of problems for me. Sometimes I accidentally resize the window a tiny bit while trying to move it (Ubuntu's 1-pixel window decorations don't help here). After that, scaling is now active and if the screen changes size again, badness ensues since the aspect ratio is skewed. Allowing zooming by 25% in and out should cover most use cases. We can add a more flexible scaling later but for now, I think this is a more friendly behavior.

2013-02-21gtk: add support for input grabbing (v2)Anthony Liguori1-5/+151
There is a small deviation from SDL's behavior here. Instead of Ctrl+Alt triggering grab, we now use Ctrl-Alt-g to trigger grab. GTK will not accept Ctrl+Alt as an accelerator since it just consists of modifiers. Having grab as a proper accelerator is important as it allows a user to override the accelerator for accessibility purposes. We also are not automatically grabbing on left-click. Besides the inability to tie mouse clicks to an accelerator, I think this behavior is hard to discover and since it only happens depending on the guest state, it can lead to confusing behavior. This can be changed in the future if there's a strong resistence to dropping left-click-to-grab, but I think we're better off dropping it.

2013-02-21ui: add basic GTK gui (v5)Anthony Liguori5-0/+615
This is minimalistic and just contains the basic widget infrastructure. The GUI consists of a menu and a GtkNotebook. To start with, the notebook has its tabs hidden which provides a UI that looks very similar to SDL with the exception of the menu bar. The menu bar allows a user to toggle the visibility of the tabs. Cairo is used for rendering. I used gtk-vnc as a reference. gtk-vnc solves the same basic problems as QEMU since it was originally written as a remote display for QEMU. So for the most part, the approach to rendering and keyboard handling should be pretty solid for GTK.

2013-02-21qom/object.c: Allow itf cast with num_itfs = 0Peter Crosthwaite1-1/+2
num_interfaces only tells you how many interfaces the concrete child class has (as defined in the TypeInfo). This means if you have a child class which defines no interfaces of its own, but its parent has interfaces you cannot cast to those parent interfaces. Fixed changing the guard to check the class->interfaces list instead (which is a complete flattened list of implemented interfaces).

2013-02-21qom/object.c: Reset interface list on inheritancePeter Crosthwaite1-0/+1
The QOM framework will attempt the recreate a classes interface list from scratch for each class. This means that a child class should zero out the list of interfaces when cloned from the parent class. Currently the list is memcpy()d from the parent to the child. As the interface list is just a pointer to a list, this means the parent and child will share the same list of interfaces. When the child inits, it will append its own interfaces to the parents list. This is incorrect as the parent should not pick up its childs interfaces. This actually causes an infinite loop at class init time, as the child will iterate through the parent interface list adding each itf to its own list(in type_initialize()). As the list is (erroneously) shared, the new interface instances for the child are appended to the parent, and the iterator never hits the tail and loops forever.

2013-02-21vga: fix byteswapping.Gerd Hoffmann6-16/+22
In case host and guest endianness differ the vga code first creates a shared surface (using qemu_create_displaysurface_from), then goes patch the surface format to indicate that the bytes must be swapped. The switch to pixman broke that hack as the format patching isn't propagated into the pixman image, so ui code using the pixman image directly (such as vnc) uses the wrong format. Fix that by adding a byteswap parameter to qemu_create_displaysurface_from, so we'll use the correct format when creating the surface (and the pixman image) and don't have to patch the format afterwards.
