It was segfaulting in loadGPoints/loadEmitters when 1) called before ps was calloc'd in preparePaint() and 2) the updating of the options was not complete, i.e. GPosx was updated but GPosy was not.

It still crashes the moment you add a new emitter in CCSM.

Something weird happens in CCSM too, every emitter appears enabled, regardless of the settings.

Michail, thanks a lot 4 investigating. Hope you can fix all the problems, but feel free to propose your branch for merging, even if it just makes things better and does not fix all of the issues...
+1 for helping here.

I think I have now fixed all the segfaults in wizard, the remaining issue is in CCSM(all emitters appear selected).

I will do some cleanup/testing and propose it.

[ Daniel van Vugt ]
  * This branch is 0.9.11

[ Hu Kang ]
  * Remove redundant src/logmessage/include/core/logmessage.h (LP:
    #1067246). (LP: #1067246)

[ Brandon Schaefer ]
  * Unrevert 3728, fix failing tests. Change the behaviour of
    undecorating windows. Previously when a window was undecorated, we
    would shift it back to an appropriate position according to its
    gravity member. That behaviour was problematic because in the
    StaticGravity case the window has to just stay in the same place.
    But then if you had a window with StaticGravity which then did get a
    decoration and later removed it, it would be placed as though it was
    decorated and appear to be in the wrong place. The correct behaviour
    is to place all windows as though they have decorations, and then
    when decorations are removed, to move the window back to the corner
    as indicated in its gravity and then expand its size to cover the
    obscured regions no longer hidden because the decorations went away.
    (LP: #1165343).   1. Completely remove decorOffsetMove and other
    related code from      decor.cpp. Put the logic to handle the
    window->input () - window->border ()      placement offset inside of
    setWindowFrameExtents instead. Now the window      will always be
    offset from its original non-decorated position to the new
         decorated position, rather than having to guess between
    decoration sizes.   2. Make saveGeometry and restoreGeometry work
    relative to window->border ()      as opposed to including it in the
    saved geometry. It is possible that the      border size might
    change during maximization, as such, we don't want to      save the
    position with the border before maximizing. Instead save the
    position      as if it were never decorated so that when the window
    is restored it can be      restored to its original position and
    then adjusted for its new border size.   3. Fix a few typoes in the
    tests.   4. Moved some commonly used matchers into compiz::testing
      5. Make COMPIZ_PLUGIN_DIR accept multiple directories and look in
    each one      of them for the plugin   6. Set COMPIZ_PLUGIN_DIR
    appropriately for each plugin that we wish to load      on startup
    so that we load locally built plugins as opposed to installed
         ones.   7. Uncomment compiz_discover_tests for the acceptance
    tests. Now they are      run by default. (LP: #1195522). (LP:
    #1195522, #1165343)
  * If we receive a stateNotifyChange, we check if we are in a max
    state. If so, overwrite the xwc with either X | W, or Y | H
    depending on the semi max state with the orig position before we
    went into a semi max state. This way when we leave any sort of max
    state the orig position is restored. If the window is being grabbed
    we do not overwrite the position, which it gets its own value at
    that point (instead of the orig pos). (LP: #892012)

[ Marco Trevisan (Treviño) ]
  * debian/patches/ubuntu-config.patch: remove grid custom keybindings
    for window management We handle these directly in unity
    (lp:~3v1n0/unity/super-arrows-shortcuts). (LP: #992697)
  * ActionMenu: weak ref the action menu on creation, and unref it on
    destroy Also, now the widget destruction automatically unset the
    menu. This makes the object to be correctly finalized (not only
    disposed) making sure the internal idle into WnckActionMenu gets
    stopped. (LP: #1191853)
  * debian/patches/ubuntu-config.patch: Don't use Ctrl+Alt+KP_0 for grid
    maximize Otherwise this clashes with default minimize key. (LP:
    #1236899)
  * Window: disable the size adjustments when decorating/undecorating
    windows. (LP: #1238111)
  * Window: resize a maximized window if the decorations changed, so
    that it will fill all the available space.
  * compiz-gnome: remove decor plugin from unity profile.

[ Michail Bitzes ]
  * Plugin wizard ported to OpenGL|ES. Use GLVertexBuffer. Enable
    building for GLES. Enable architectures armel and armhf. (LP:
    #1196003). (LP: #1196003)
  * Wizard plugin: No more segfaults/crashes when changing options in
    CCSM. (LP: #1195996) Gradual fade out of particles when terminating.
    (LP: #1196010) Typo fixed in wizard.xml.in. optionNotify added for
    some options that were missing it. Code cleanup: Declare variables
    outside of loops. Functions moved from class WizardScreen to class
    ParticleSystem. (similar to firepaint/showmouse) We just enable
    GL_BLEND if it is disabled and we just disable GL_BLEND if it was
    disabled before. Many other style and indentation fixes. (LP:
    #1196010, #1195996)
  * Plugin showrepaint ported to OpenGL|ES. Use GLVertexBuffer. Enable
    building for GLES. Enable architectures armel and armhf. .

[ Chris Townsend ]
  * Removed logic in the calculateWallOffset() function in the Expo
    plugin that only accounted for offsetting the expo animation on the
    left-most and top-most monitor. Also removed the
    TestNoOffsetIfOutputIsNotOrigin test since this test is now invalid.
    (LP: #1031710)
  * Ctrl-Alt-Del should open the gnome-system-monitor at the processes
    tab. This fix uses the commands plugin to override the default
    action. This includes: - Install the commands plugin by default. -
    Breaks/Replaces the compiz-plugins package for versions earlier than
    0.9.10. - Patch commands.xml and integrated.xml to map gnome-system-
    monitor to Ctrl-Alt-Del by default. - Start the command plugin upon
    Compiz starting. (LP: #890747)
  * Alt-Tabbing or Launcher selecting a window that is over 50% in a
    different viewport should not switch the viewport nor change the
    placement of the window. The fix is to add an option to turn this
    behavior on or off. By default, the option is on, but Ubuntu is
    patched to turn it off to fix this bug. (LP: #1092323)
  * Fix regression when selecting apps on a different viewport than the
    current one will no longer automatically switch the viewport. (LP:
    #1228352)
  * Fix issue where non-resizable windows and semi-maximized window
    would have an area near the top of the title bar that could not be
    grabbed. (LP: #1228507)
  * Remove seemingly useless code in the SnapWindow::resizeNotify()
    method where a snapped window that is being resized on the opposite
    side of the snap would cause orders of magnitude more calls to
    window->resize() and kill performance. (LP: #1019139)
  * Need to revert rev. 3798 because it has a bad side effect of
    "hanging" all of the windows when restarting Compiz and rendering
    the desktop unusable.
  * Bump ABI version due to some recent changes.
  * When saving window geometry when going into maximized/semi-
    maximized, also save for grabbed windows as well. This fixes a
    desktop hang condition. (LP: #1244754)
  * Second part of the fix to keep the workspace from automatically
    switching when more than half of the window is contained in another
    workspace. (LP: #1092323)
  * Add new Grid shortcuts for Ctrl-Super-Left/Right to left/right semi-
    maximize windows (removed from Unity). Patch Grid to use Ctrl-Super-
    Up to maximize a gridded window instead of using core. This helps in
    restoring a window back to it's original place before being gridded.
    Account for left and right borders when restoring a gridded window
    since the window would shrink and shift by this amount. (LP:
    #1251777)

[ James Jones ]
  * OpenGL contexts are reference counted and only destroyed once they
    are no longer current to any thread. To ensure the context really is
    destroyed, lose current from it before destroying it. (LP: #1213809)

[ Sami Jaktholm ]
  * Expo plugin: 1) Always fetch the dndButton action in dndFini. The
    action given to dndFini might be a key or edge binding action if
    expo was terminated during window DnD. We shouldn't set their state
    to CompAction::StateInitButton or the bindings break. 2) Pass NULL
    action to termExpo if invoked from handleEvent Previously we passed
    the action of expoKey to termExpo which in turn passed it to
    dndFini. DndFini changed the action state to
    CompAction::StateInitButton that broke the keybinding. Now that
    dndFini fetches the dndButton action itself, there's no need to
    fetch it in handleEvent too as dndFini is the only one using the
    action. (LP: #1131106)
  * Expo: Cast denominators of integer divisions to floats before
    performing a matrix translation to viewports with the results.
    Otherwise rounding errors in cases the results are not an integers
    cause the viewports to be painted offscreen. (LP: #438580)
  * Port dbus introspection to compiz 0.9. move xml creation to a
    separate class (IntrospectionResponse) for easier. memory management
    (allocate buffer and writer in ctor, free in dtor). move duplicated
    response sending code to a separate method that takes.
    IntrospectionResponse and sends the resulting xml. Refactor
    handle*IntrospectMessage to work with compiz 0.9 interfaces. This
    also fixes the broken list method which was a result of logic error.
    The code to invoke list handler was never reached. This fixes most
    of the issues noted in bug 749084. (LP: #749084)
  * Bias the current viewport in addWindowSizeChanges. If window is
    visible in the current viewport, use that viewport when calculating
    geometries in addWindowSizeChanges. Otherwise the current method is
    used. This way visible windows are maximized in the current
    viewport. However, offscreen windows won't jump back to the active
    viewport if window maximizes by itself or addWindowSizeChanges is
    called for some other reason. (LP: #776435)
  * Expo: Recompute glow quads if a desktop window is resized. (LP:
    #1090713). (LP: #1090713)
  * Decor: Use maximized border extents only if window is fully
    maximized. The decorator draws a normal border around semi-maximized
    windows. When maximized border extents were used for semi-maximized
    windows, compiz didn't reserve any space for the border in its
    geometry calculations. At least following problems are a result of
    this behavior: Semi-maximized windows have 1px borders drawn on
    adjacent workspaces. (LP: #986051). Grid placed window overlaps the
    adjacent viewport (LP: #898870). (LP: #986051, #898870)

[ MC Return ]
  * Fade plugin, minor code cleanup: Declaration and assignment of local
    variables in one line. Merged if condition checks. Use pre- instead
    of postfix de- and increments. Removed redundant brackets. Added and
    removed newlines. Fixed indentation.
  * Opacify code cleanup: Declaration of local variables outside of
    loops. Calculate activeOpacity and targetOpacity just once, not for
    each window. Use prefix instead of postfix increments. Merged if
    condition checks. Declaration and assignment of local variables in
    one line. Added and removed newlines. Removed redundant brackets.
    Fixed indentation. Opacify, functionality fix: Improved the toggling
    logic by setting isToggle in the constructor according to the
    startup setting, then calling setFunctions (isToggle);,which then
    calls screen->handleEventSetEnabled (os, os->isToggle); to fix
    Opacify ignoring the "Toggle Opacify on by default" setting. (LP:
    #787814). (LP: #787814)
  * Widget, minor code cleanup: Declaration and assignment of local
    variables in one line. Merged if condition checks. Added and removed
    newlines. Added default case to switch (just a style issue). Removed
    redundant brackets. Fixed indentation.
  * window.cpp code cleanup: Declare variables outside of loops. Reduced
    the scope of variables. Do not assign values to variables if those
    values are not used. Always bail out of functions ASAP, do not
    calculate stuff you might not need. Use pre- instead of postfix de-
    and increments. Declaration and assignment of variables in one line.
    Merged if condition checks. Added and removed brackets. Added and
    removed newlines. Fixed indentation. Added TODOs (removal of magic
    numbers).
  * Fix for cube.cpp, regression r3720 - Inner sides of cube invisible
    now. Wrong variable type was accidentially used, cullInv is of type
    int, not bool. (LP: #1183852). (LP: #1184852, #1183852)
  * src/output*.cpp cleanup: Return ASAP, do not calculate stuff you do
    not need. Declaration and assignment of variables in one line.
    Declare local variables outside of loops. Use prefix instead of
    postfix increment. Added and removed newlines. Fixed indentation.
  * Expo, code cleanup: Declaration of local variables outside of loops.
    Use prefix instead of postfix increments. Declaration and assignment
    of local variables in one line, if possible. Reduced the scope of
    some variables. Removed redundant brackets. Used static_cast <>
    (type) instead of (type) cast. Added and removed newlines if
    appropriate. Fixed indentation. Added TODOs. Expo, speed
    improvements: Do not calculate screen->vpSize ().width () and
    screen->vpSize ().height () multiple times, instead save them in the
    unsigned ints vpCountHorz and vpCountVert and use those variables
    instead. Speed up the curve calculations by using additional
    variables to save results to not have to re-calculate those all the
    time. The new variables introduced are degToRad, screenWidth,
    screenWidthSquared, curveDistSquaredPlusQuarter,
    pOne2MinusCurveDist, v0Squared and v2Squared. Also introduced const
    float halfGapX = gapX / 2.0 and used this variable in the
    calculations of curveDistance and curveRadius. Simplified
    calculations of this type: (M_PI / 180.0f) * curveAngle / 2.0, which
    is equal to: (M_PI / 360.0f) * curveAngle Do not call
    optionGetGroundSize (); twice, instead save the value in the float
    groundSize and use that variable in the following calculations.
    Removed the creation of the redundant bool hide, which is just used
    once in an if-condition check. It does not help to have this bool.
    Try to avoid redundant GL_BLEND state changes, they are expensive -
    only enable GL_BLEND if it is disabled and just disable it, if it
    was disabled before, otherwise do nothing. Try to avoid redundant GL
    filter changes - just query the filter state if the mipmap option in
    CCSM is enabled. Also just set back the filter to the previous state
    if we actually changed it, otherwise do nothing. -5.5f * 2 = -11.0f.
    No need to calculate M_PI / 180.0f 720 times: Calculate this value
    once instead and save it in the const float mpi, use mpi in the
    following looped calculations. Use const int scw in the same loop
    instead of calling screen->width () 360 times. glow.cpp: Massively
    increased calculation speed of the glow texture: No need for any
    macros here -> removed them and replaced them with local variables.
    Precalculate values, store them in local variables and use those in
    the following calculations (new variables are the ints winRealX,
    winRealY, winRealWidth, winRealHeight, halfWinRealWidth,
    halfWinRealHeight, xPlusHalfWidth, yPlusHalfHeight, xPlusGlowOff,
    yPlusGlowOff, xMinusGlowOff, yMinusGlowOff and the float glowPart).
    Used w->geometry ().widthIncBorders () and w->geometry
    ().heightIncBorders () to determine winRealWidth and winRealHeight.
    Expo, fixes: Do not force "One wall per output" on the user, if his
    displays use different resolutions. "One big wall" makes a lot of
    sense for many multi-screen configs, where not all of the screens
    have exactly the same resolution, so if the user explicitely chooses
    this mode, Compiz should respect the user's choice. (LP: #1009592).
    (LP: #1009592)
  * Compiz, redundant and outdated files cleanup: Removed outdated NEWS
    files. Removed outdated AUTHORS and ChangeLog files. Removed
    plugins/freewins/COPYING - we do not need another copy of the GPL v2
    here. Removed another copy of the GPL v2 from plugins/workarounds.
    This will reduce package sizes, download time and bring some order
    to chaos.
  * Expo, .xml.in fixes: Better description of the plugin. Improved and
    fixed tooltips. Moved the "Curve Strength" option closer to
    "Deformation". Refreshed the quilt patch for Ubuntu: There is no
    need to set the default distance to 0.005 as this setting has no
    effect without deformation. Set default multi-screen mode to "One
    wall per output" for Ubuntu, because "One big wall" works now for
    all display configurations and could potentially change the
    appearance for Ubuntu users. (LP: #1074487). (LP: #1074487)
  * Added contribute directory. Added QtCreatorConfig.xml, a
    configuration file for Qt Creator, which adjusts Qt Creator's C++
    indentation style to be the same that is used in the Compiz project
    (X11, mixed spaces and tabs).
  * Mousepoll: Fixed mousepoll version mismatch. (COMPIZ_MOUSEPOLL_ABI
    was missing) (LP: #1195659). (LP: #1195659)
  * Expo: Simplified the GL filter handling.
  * Fixed broken text in all plugins (missing COMPIZ_TEXT_ABI). (LP:
    #1196493). (LP: #1196493)
  * CCSM: Fixed vertical alignment of the text on the stylized keys.
    (Shift, Super, Ctrl, Alt) (LP: #1196345). (LP: #1196345)
  * Thumbnail, cleanup: Merged if condition checks. Declaration of
    variables when they are needed (C++ style). Removed redundant
    brackets. Removed useless "/* Could someone please explain how this
    works */" comment. Removed extern const unsigned short
    TEXT_DISTANCE, because this variable does not exist anymore (value
    is configurable already). Changed if (something > 0.0) to if
    (something), 10 times. Changed pointedWin = 0; to pointedWin =
    NULL;. Used centerX () and centerY () abstractions from
    compiz::window::Geometry to determine the icon center coordinates.
    Added and removed newlines, if appropriate. Fixed indentation.
    Thumbnail, code speedup: Return ASAP, do not calculate stuff you
    might not need. No need for WIN_W (w) and WIN_H (w) macros, removed
    those and replaced them with the local variables int winWidth, int
    winHeight, int dockWidth and int dockHeight. No need for WIN_X (w)
    and WIN_Y (w) macros, replaced those with int dockX and int dockY.
    Introduced int tHeight = thumb.height;, int tWidth = thumb.width;,
    int halfTWidth = tWidth / 2; and int halfTHeight = tHeight / 2; and
    used those variables in the following calculations. Use
    igMidPoint[0] and igMidPoint[1] as arguments in the screen-
    >outputDeviceForPoint (arg1, arg2) function, instead of re-
    calculating the arguments again. Thumbnail, GL speedup: Introduced
    GLfloat wxPlusWidth = wx + width;, GLfloat wyPlusHeight = wy +
    height;, GLfloat wxPlusWPlusOff = wxPlusWidth + off;, GLfloat
    wyPlusHPlusOff = wyPlusHeight + off;, GLfloat wxMinusOff = wx - off;
    and GLfloat wyMinusOff = wy - off; and used those coordinates in the
    vertexData arrays. No need to re- calculate those values multiple
    times. Just query optionGetShowDelay () once and use int showDelay
    later. We just enable blending if it is currently disabled and
    disable blending only, if it was disabled before.
  * src/session.cpp cleanup: Declaration and assignment of local
    variables in one line. (this *should* fix bug #1101405) Use pre-
    instead of postfix increments. Added and removed newlines. Added
    missing break (just a style issue). Fixed indentation. (LP:
    #1101405). (LP: #1101405)
  * Firepaint, code cleanup: Declare variables outside of loops.
    Declaration and assignment of local variables in one line. Use pre-
    instead of postfix increment. Removed redundant newlines. Removed
    redundant casts. (from (float) optionGetFireColor) Removed redundant
    brackets. Added missing break (style issue only). Added comment and
    TODO. Fixed indentation. Firepaint, speedup: We just enable GL_BLEND
    if it is disabled and we just disable GL_BLEND if it was disabled
    before. Introduced the GLfloats xMinusW, xPlusW, yMinusH and yPlusH
    to store calculated coordinates instead of recalculating them
    multiple times. Introduced float fireLife = optionGetFireLife ();,
    float fireWidth = optionGetFireSize ();, float fireHeight =
    fireWidth * 1.5f; and bool mystFire = optionGetFireMystical (); and
    used those variables inside the loop. Firepaint, .xml.in cleanup:
    Firepaint now has 2 tabs, 'General' and 'Particle Settings'. The
    name of this plugin is Firepaint, <short> should not contain the
    description. Better description of the plugin. Uppercase option
    titles. Punctuation for tooltips. Improved tooltips. Firepaint,
    fixes: Initialize all class member variables in the ParticleSystem::
    ParticleSystem () ctor (LP: #1101512, LP: #1101580). (LP: #1101512,
    #1101580)
  * img* plugins code cleanup: Always bail out of function ASAP, do not
    calculate stuff you might not need. Declare variables outside of
    loops so they won't be re-declared in each loop. Use prefix instead
    of postfix increments. Declaration and assignment of variables in
    one line. Merged if condition checks. Added and removed brackets.
    Added and removed newlines, if appropriate. Minor code structure
    improvements, declare variables when you need them, not much
    earlier. Fixed indentation.
  * Text, speed improvements: Introduced const float halfPi = PI / 2.0f;
    and const float triHalfPi = halfPi * 3; and used those to draw the
    rounded background. Introduced GLfloat xPlusWidth = x + width; and
    GLfloat yMinusHeight = y - height; and used those coordinates for
    the vertexData array. Text, cleanup: Declaration of local variables
    outside of loops. Fixed indentation.
  * cube.cpp, code cleanup: #include "privates.h", not <privates.h>.
    Merged if condition checks. Declaration of variables, where you need
    them to improve the code structure and readability. Use C++ standard
    bool for topDir, bottomDir, allCaps and mCapsPainted[output] (bool
    true/false instead Bool TRUE/FALSE). Initialize all of the class
    member variables in the constructor. Replaced if (priv->mSky.size ()
    > 0) with if (!priv->mSky.empty ()). Removed redundant brackets.
    Fixed indentation. Added TODO. cube.cpp, code speedup: Do not call
    optionGetInactiveOpacity () twice, instead save the value as float
    inactiveOpacity and use this variable in the following calculation.
    Introduced the variables float halfHsize = hsize / 2.0; and float
    tsSize = 360.0f / size; and used those in following calculations to
    not have to recalculate those values multiple times. Do not
    calculate M_PI / sides and 2 * M_PI / sides multiple times in loops,
    instead save those values in the GLfloats mps and tmps and use those
    values inside the loops. Use GLdouble mDist2 = 0.5 / mDistance; in
    the GLdouble clipPlane* arrays, instead of recalculating this value
    multiple times. Use GLfloat oneMinusFStepX = 1.0f - fStepX; and
    GLfloat oneMinusFStepY = 1.0f - fStepY; instead of calculating those
    values multiple times. Use float outputWidth = outputPtr->width ();
    and float outputHeight = outputPtr->height (); instead of calling
    the functions multiple times. Introduced the GLfloat normInvert =
    0.5f * invert; and used this variable instead of recalculating this
    value multiple times. Introduced the GLfloats mSkyWidth and
    mSkyHeight and used those in the following loops instead of calling
    mSkySize.width () and mSkySize.height () multiple times. Try to
    avoid redundant GL_BLEND state changes, because OpenGL will blindly
    change the global state, no matter what it currently is set to and
    that state change is expensive. So we query and save the actual
    blending state in the variable GLboolean glBlendEnabled =
    glIsEnabled (GL_BLEND); and just enable it if it isn't already and
    just disable it, if it was disabled before. (LP: #1101422, LP:
    #1195977) cube.cpp, other fixes: Return false in function
    PrivateCubeScreen::updateGeometry (int, int) if sides should ever be
    0, which should never happen, but should make Coverity happy. (LP:
    #1101541) Initialize all class member variables in the
    PrivateCubeScreen:: PrivateCubeScreen (CompScreen *) constructor.
    (mTc, mNOutput, mOutput, mOutputMask, mCleared, mCapsPainted) (LP:
    #1101575). (LP: #1195977, #1101541, #1101422, #1101575)
  * plugins/ezoom/src/ezoom.cpp: Also initialize xtrans and ytrans in
    the ctors. Just just enable blending if it is disabled and just
    disable it if it was disabled before. Introduced the variables
    oWidth, oHeight, halfOWidth and halfOHeight to speed up following
    calculations. Return ASAP, do not calculate possibly redundant
    stuff. Declaration and assignment of local variables in one line.
    Improved readability. Added and removed newlines. Minor indentation
    fixes. plugins/ezoom/ezoom.xml.in: Removed redundant whitespaces
    from a tooltip. (LP: #1101572). (LP: #1101572)
  * gears.cpp, gears.h: Do not render the gears if we are viewing the
    cube from the inside - the gears are otherwise obstructing the
    users' view on his workspaces. Print a warning to the console once
    in this case. (LP: #1185819). (LP: #1185819)
  * Animation code cleanup: Return ASAP, do not calculate stuff you
    might not need. Declare CompWindow *w, AnimWindow *animWin,
    PrivateAnimWindow *aw and Animation *curAnim outside the for loop.
    grid.cpp: Declare float x, y, topiyFloat outside the for loop.
    options.cpp: Declare unsigned int nOptions outside the foreach loop.
    Use pre- instead of postfix de- and increments. Declaration and
    assignment of variables in one line. Merged if condition checks.
    Added and removed brackets. Added and removed newlines. Fixed
    indentation. Also initialize the non-static class members
    "mGridWidth" and "mGridHeight" in the GridAnim::GridAnim ctor. (LP:
    #1101618). (LP: #1101618)

[ Andrea Azzarone ]
  * Satisfy matchers on getProperty as soon as they are set. The order
    of evaluation for matchers in Google Mock appears to be undefined -
    this means that we can't rely on the first argument being matched
    first and the second argument being matched afterwards. In turn,
    this means that any GValue may be passed to a GValueMatch which, by
    a design flaw, is unable to handle any values of a type it does not
    expect (at least not without an API change). It will silently pass
    the incorrect type to g_type_get_* which causes internal assertion
    failures. At the moment we're just interleaving the calls to
    getProperty and get_property - that way the expectations are
    satisfied and go away as soon as they're set. This in turn means
    that Google Mock only has to traverse one matcher rather than
    multiple matchers. (LP: #1187468). (LP: #1187468)
  * Extends invisible borders to the title bar too. (LP: #717444). (LP:
    #717444)
  * Disable grid/put_maximize_key on ubuntu.
  * Port to new gmock. Disable some faling tests because of weird leaks.
    (LP: #1185265)
  * Update window geo only on new decoration size only if mapped. (LP:
    #1198000). (LP: #1198000)
  * Disable show_desktop_key by default on ubuntu. Will provide the same
    option under the unityshell panel. (LP: #1204664)
  * Use Glib::RefPtr<Glib::Source> in glib_integration_test. After the
    fix of bug https://bugzilla.gnome.org/show_bug.cgi?id=561885
    Glib::Source::~Source is called when both Source::unreference() and
    SourceCallbackData::destroy_notify_callback() are called. (LP:
    #1214459)
  * Terminate scale on mouse click on an empty area. (LP: #1234624)

[ Sam Spilsbury ]
  * Change the behaviour of undecorating windows. Previously when a
    window was undecorated, we would shift it back to an appropriate
    position according to its gravity member. That behaviour was
    problematic because in the StaticGravity case the window has to just
    stay in the same place. But then if you had a window with
    StaticGravity which then did get a decoration and later removed it,
    it would be placed as though it was decorated and appear to be in
    the wrong place. The correct behaviour is to place all windows as
    though they have decorations, and then when decorations are removed,
    to move the window back to the corner as indicated in its gravity
    and then expand its size to cover the obscured regions no longer
    hidden because the decorations went away. (LP: #1165343). (LP:
    #1165343)
  * Added some new hooks to PluginClassHandler to allow a VTable to
    specify if loaded. PluginClassHandler::get () was designed to simply
    instantiate an instance of that class for the core structure, but it
    did this without checking if the plugin was loaded. Added some new
    methods to PluginClassHandler exposed by LoadedPluginClassBridge and
    only accessible by those who implement PluginKey to specify globally
    whether or not a plugin is actually loaded, so that
    PluginClassHandler can return accordingly. Integration and unit
    tests added as appropriate (LP: #1169620) (LP: #1101026). (LP:
    #1101026, #1169620)
  * Satisfy matchers on getProperty as soon as they are set. The order
    of evaluation for matchers in Google Mock appears to be undefined -
    this means that we can't rely on the first argument being matched
    first and the second argument being matched afterwards. In turn,
    this means that any GValue may be passed to a GValueMatch which, by
    a design flaw, is unable to handle any values of a type it does not
    expect (at least not without an API change). It will silently pass
    the incorrect type to g_type_get_* which causes internal assertion
    failures. At the moment we're just interleaving the calls to
    getProperty and get_property - that way the expectations are
    satisfied and go away as soon as they're set. This in turn means
    that Google Mock only has to traverse one matcher rather than
    multiple matchers. (LP: #1187468). (LP: #1187468)
  * Revert revision 3278.
  * Immediately update the window matrices and regions if the number of
    textures changed. (LP: #1189369). (LP: #1189369)
  * Provide a basic decor plugin acceptance test suite. This change
    provides a simple acceptance test suite for the decor plugin. It
    creates a fake window decorator (cdt::FakeDecorator) and allows
    users to create fake decorations (eg cdt::FakePixmapDecoration)
    which can be serialized as decoration properties and set on windows
    under xorg-gtest. It also launches compiz with the opengl, composite
    and decor plugins loaded and runs some basic tests. Among them:
    BaseDecorAcceptance. Startup: Basic canary "can we start compiz with
    these plugins" test
    FakeDecoratorSessionOwnerNameSetOnSelectionOwner: Create a fake
    decorator, ensure that libdecoration sets our session name "fake" on
    the selection owner FakeDecoratorReceiveClientMessage: Create fake
    decorator, ensure that libdecoration posts a client message to the
    root window announcing that the new decorator exists.
    DecorationSupportsWindowType: Create a fake decorator, announce
    support for the WINDOW type decorations and ensure that the correct
    atom is set on the session owner window.
    DecorationSupportsPixmapType: Create a fake decorator, announce
    support for the PIXMAP type decorations and ensure that the correct
    atom is set on the session owner window.
    DecorFakeDecoratorAcceptance. WindowDefaultFallbackNoExtents: By
    default, newly created windows should recieve a fallback decoration
    but they should not have any frame extents.
    DecorWithPixmapDefaultsAcceptance. These tests create a default
    pixmap decoration to use in the hypothetical situation that the
    window decorator hasn't yet generated a decoration for this window.
    FallbackRecieveInputFrameNotify: Verify that we get a
    _COMPIZ_WINDOW_DECOR_INPUT_FRAME property set on the client when it
    is created and mapped (eg, an input frame window was annonuced to be
    created) FallbackHasInputFrameInParent: Verify that a second window
    exists in the frame window after this message was recieved.
    FallbackNormalWindowExtentOnDecoration: Verify that
    _NET_FRAME_EXTENTS is set to the default window extents for the
    default decoration when the window was mapped.
    FallbackNormalWindowInputOnFrame: Verify that the input window
    matches the extents set. PixmapDecoratedWindowAcceptance. These
    tests create a new window and an associated unique decoration for
    that window. MaximizeBorderExtentsOnMaximize: Maximize the window
    and ensure that the correct border extents are used.
    MaximizeBorderExtentsOnVertMaximize: Vertically maximize the window
    and ensure that the correct border extents are used.
    MaximizeBorderExtentsOnHorzMaximize: Horizontally maximize the
    window and ensure that the correct border extents are used.
    MaximizeFrameWindowSizeEqOutputSize: Maximie the window and ensure
    that the frame window exactly equals the output size.
    VertMaximizeFrameWindowSizeEqOutputYHeight: Maximize the window and
    ensure that the frame window's Y and Height values are consistent
    with the output size. HorzMaximizeFrameWindowSizeEqOutputXWidth:
    Ditto horizontal maximization.
    DISABLED_VertMaximizeFrameWindowSizeSameXWidth: Maximize the window
    vertically and ensure that the frame window's border-relative X
    position and width does not change. This test is disabled, as the
    behavior in compiz is currently broken, (but it means that we can
    fix it later and enable the test).
    DISABLED_HorzMaximizeFrameWindowSizeSameYHeight Maximize the window
    horizontally and ensure that the frame window's border-relative Y
    position and height does not change. This test is disabled, as the
    behavior in compiz is currently broken, (but it means that we can
    fix it later and enable the test). (LP: #1188900). (LP: #1188900)
  * Only mark for no further instantiations once we've finished
    destructing the plugin (LP: #1193596). (LP: #1193596)
  * Add more acceptance tests for the decor plugin.
    PixmapDecoratedWindowAcceptance. UndecoratedWindowExpandToOrigSize
    Test that upon undecoration, the window has exactly the same
    geometry as it did before decoration.
    DISABLED_UndecorateStaticGravityWindow Tests that for windows with a
    static gravity, the window has exactly the same geometry as it did
    before decoration. Disabled, as core is currently not moving the
    window with the static gravity back to where it started.
    AdjustmentExtents/PixmapDecorationAdjustment.
    AdjustRestoredWindowBorderMovesClient/P Test that changing the
    border extents causes the client window's absolute geometry to
    change. DISABLED_AdjustRestoredWindowBorderShrinkClient/P Tests that
    changing the border extents causes the client window's absolute
    geometry to shrink by the amount of border. Disabled, as the current
    behavior is to expand the frame window as opposed to shrinking the
    client (but this will be changed).
    DISABLED_ClientExpandsAsBorderShrinks/P Tests that as the border
    shrinks away, the client expands back to its original size.
    Disabled, as the current behavior is to expand the frame window as
    opposed to shrinking the client (but this will be changed).
    DISABLED_ClientExpandsAsBorderShrinksWhilstMaximized/P Tests that
    even if the client is maximized, if the restored border shrinks away
    it demaximizes back to the same position while also accounting for
    any change in the restored window border size. Disabled, as the
    current behavior is to expand the frame window as opposed to
    shrinking the client (but this will be changed).
    DISABLED_ClientExpandsAsBorderShrinksWhilstUndecorated/P Tests that
    even when the client is not permitted to be decorated because the
    decoration hint was removed, when it is redecorated it will be moved
    to the correct position taking into account any changes in its
    border size. Disabled, as the current behavior is to expand the
    frame window as opposed to shrinking the client (but this will be
    changed). DISABLED_AdjustRestoredWindowInputNoMoveClient/P Tests
    that adjusting the input extents (as independent from the border
    extents) of the client does not cause the client to move. Disabled,
    as this behavior appears to be broken in core. Move the
    "GetImmediateParent" function into the compiz::testing namespace so
    that it can be used by other tests. (LP: #1188900)
  * Unrevert 3728, fix failing tests. Change the behaviour of
    undecorating windows. Previously when a window was undecorated, we
    would shift it back to an appropriate position according to its
    gravity member. That behaviour was problematic because in the
    StaticGravity case the window has to just stay in the same place.
    But then if you had a window with StaticGravity which then did get a
    decoration and later removed it, it would be placed as though it was
    decorated and appear to be in the wrong place. The correct behaviour
    is to place all windows as though they have decorations, and then
    when decorations are removed, to move the window back to the corner
    as indicated in its gravity and then expand its size to cover the
    obscured regions no longer hidden because the decorations went away.
    (LP: #1165343).   1. Completely remove decorOffsetMove and other
    related code from      decor.cpp. Put the logic to handle the
    window->input () - window->border ()      placement offset inside of
    setWindowFrameExtents instead. Now the window      will always be
    offset from its original non-decorated position to the new
         decorated position, rather than having to guess between
    decoration sizes.   2. Make saveGeometry and restoreGeometry work
    relative to window->border ()      as opposed to including it in the
    saved geometry. It is possible that the      border size might
    change during maximization, as such, we don't want to      save the
    position with the border before maximizing. Instead save the
    position      as if it were never decorated so that when the window
    is restored it can be      restored to its original position and
    then adjusted for its new border size.   3. Fix a few typoes in the
    tests.   4. Moved some commonly used matchers into compiz::testing
      5. Make COMPIZ_PLUGIN_DIR accept multiple directories and look in
    each one      of them for the plugin   6. Set COMPIZ_PLUGIN_DIR
    appropriately for each plugin that we wish to load      on startup
    so that we load locally built plugins as opposed to installed
         ones.   7. Uncomment compiz_discover_tests for the acceptance
    tests. Now they are      run by default. (LP: #1195522). (LP:
    #1195522, #1165343)
  * Add a simple script for making releases.
  * Port to new gmock. Disable some faling tests because of weird leaks.
    (LP: #1185265)
  * Don't add the frame to the toplevel stack if it hasn't been created
    yet. In the event that a window is unreparented or destroyed, we
    usually need to add its frame window to the toplevel window stack
    until the time at which we recieve a DestroyNotify for it, as there
    may be incoming ConfigureNotify events puporting to stack other
    windows relative to that frame. However, this does not apply in the
    case where we have not yet received a CreateNotify for the frame
    window. In that case, it is not possible for any stacking requests
    to be made relative to this window, so it does not need to be added
    immediately. Instead, we can add it at the time that we recieve a
    CreateNotify for it as a regular override redirect window until the
    time that it is later destroyed. (LP: #1171314). (LP: #1171314)
  * Remove redundant src/logmessage/include/core/logmessage.h (LP:
    #1067246). (LP: #1067246)
  * Adjust acceptance tests for the fix to LP: #1198000 1. Always set
    frame extents before updating the frame 2. Added
    COMPIZ_NO_CONFIGURE_BUFFER_LOCKS so that we don't have to deal with
    the delayed configure requests logic in the tests where it does not
    help 3. Split restoredDecorationSize in to
    restoredDecorationBorderSize and restoredDecorationInputSize so that
    we can measure the size of the decoration both in terms of its
    visible and invisible border 4. Wait for the default decoration
    properly 5. Capture the initial geometry of the window with and
    without decorations when the window gets its first decoration. Use
    these values to calculate the size changes in the window from then
    on instead of its creation values 6. Just flag when the window was
    first decorated in setWindowFrameExtents rather than checking if it
    is mapped. We only want to not resize the window once. (LP:
    #1198000)
  * Release version 0.9.10.0
  * Bump VERSION to 0.9.10.2
  * Ensure that the frame region is always set as soon as the window is
    decorated. Further ensure that the window decoration isn't
    needlessly reset if the window already had one. Refactored XShape
    usage into a common function. Added tests to verify the behaviour of
    shape set on initially creating a decorated window and also upon
    changing the input frame window shape (LP: #1158267). (LP: #1158267)
  * Add support for the GLX_EXT_buffer_age extension on hardware that
    supports it, which should result in a nice speed-boost due to the
    fact that we no longer have to abuse fillrate by retaining old frame
    contents, and instead asking the driver how defined the current
    frame is. (LP: #1024304)
