From: Ville Syrjälä <[email protected]> Eliminate the internal MapWindow+UnmapWindow cycle around window redirection changes. Instead do the work in a single pass by marking the afected windows and calling ValidateTree and HandleExposures directly. This gets rid of unnecessary expose events, and invalid ClipNotify calls during rediredction changes. Now ClipNotify will only get called with the final clip values, and expose events are only sent to areas that actually got exposed.

Instead I added a few !anyMarked tests to avoid walking the subtree multiple times. composite/compalloc.c | 87 +++++++++++++++++++++++++----------------------- 1 files changed, 45 insertions(+), 42 deletions(-) diff --git a/composite/compalloc.c b/composite/compalloc.c index c615a4c..8130948 100644 --- a/composite/compalloc.c +++ b/composite/compalloc.c @@ -104,6 +104,35 @@ compDestroyDamage (DamagePtr pDamage, void *closure) cw->damage = 0; } +static Bool +compMarkWindows(WindowPtr pWin, + WindowPtr *ppLayerWin) +{ + ScreenPtr pScreen = pWin->drawable.pScreen; + WindowPtr pLayerWin = pWin; + + if (!pWin->viewable) + return FALSE; + + (*pScreen->MarkOverlappedWindows)(pWin, pWin, &pLayerWin); + (*pScreen->MarkWindow)(pLayerWin->parent); + + *ppLayerWin = pLayerWin; + + return TRUE; +} + +static void +compHandleMarkedWindows(WindowPtr pWin, WindowPtr pLayerWin) +{ + ScreenPtr pScreen = pWin->drawable.pScreen; + + (*pScreen->ValidateTree)(pLayerWin->parent, pLayerWin, VTOther); + (*pScreen->HandleExposures)(pLayerWin->parent); + if (pScreen->PostValidateTree) + (*pScreen->PostValidateTree)(pLayerWin->parent, pLayerWin, VTOther); +} + /* * Redirect one window for one client */ @@ -112,8 +141,9 @@ compRedirectWindow (ClientPtr pClient, WindowPtr pWin, int update) { CompWindowPtr cw = GetCompWindow (pWin); CompClientWindowPtr ccw; - Bool wasMapped = pWin->mapped; CompScreenPtr cs = GetCompScreen(pWin->drawable.pScreen); + WindowPtr pLayerWin; + Bool anyMarked = FALSE; if (pWin == cs->pOverlayWin) { return Success; @@ -163,12 +193,8 @@ compRedirectWindow (ClientPtr pClient, WindowPtr pWin, int update) free(cw); return BadAlloc; } - if (wasMapped) - { - DisableMapUnmapEvents (pWin); - UnmapWindow (pWin, FALSE); - EnableMapUnmapEvents (pWin); - } + + anyMarked = compMarkWindows (pWin, &pLayerWin); /* Make sure our borderClip is correct for ValidateTree */ RegionNull(&cw->borderClip); @@ -190,16 +216,9 @@ compRedirectWindow (ClientPtr pClient, WindowPtr pWin, int update) return BadAlloc; if (ccw->update == CompositeRedirectManual) { - /* If the window was CompositeRedirectAutomatic, then - * unmap the window so that the parent clip list will - * be correctly recomputed. - */ - if (pWin->mapped) - { - DisableMapUnmapEvents (pWin); - UnmapWindow (pWin, FALSE); - EnableMapUnmapEvents (pWin); - } + if (!anyMarked) + anyMarked = compMarkWindows (pWin, &pLayerWin); + if (cw->damageRegistered) { DamageUnregister (&pWin->drawable, cw->damage); @@ -213,15 +232,9 @@ compRedirectWindow (ClientPtr pClient, WindowPtr pWin, int update) FreeResource (ccw->id, RT_NONE); return BadAlloc; } - if (wasMapped && !pWin->mapped) - { - Bool overrideRedirect = pWin->overrideRedirect; - pWin->overrideRedirect = TRUE; - DisableMapUnmapEvents (pWin); - MapWindow (pWin, pClient); - EnableMapUnmapEvents (pWin); - pWin->overrideRedirect = overrideRedirect; - } + + if (anyMarked) + compHandleMarkedWindows (pWin, pLayerWin); return Success; } @@ -235,7 +248,8 @@ compFreeClientWindow (WindowPtr pWin, XID id) { CompWindowPtr cw = GetCompWindow (pWin); CompClientWindowPtr ccw, *prev; - Bool wasMapped = pWin->mapped; + Bool anyMarked = FALSE; + WindowPtr pLayerWin; if (!cw) return; @@ -252,12 +266,7 @@ compFreeClientWindow (WindowPtr pWin, XID id) } if (!cw->clients) { - if (wasMapped) - { - DisableMapUnmapEvents (pWin); - UnmapWindow (pWin, FALSE); - EnableMapUnmapEvents (pWin); - } + anyMarked = compMarkWindows (pWin, &pLayerWin); if (pWin->redirectDraw != RedirectDrawNone) compFreePixmap (pWin); @@ -278,15 +287,9 @@ compFreeClientWindow (WindowPtr pWin, XID id) pWin->redirectDraw = RedirectDrawAutomatic; DamageDamageRegion(&pWin->drawable, &pWin->borderSize); } - if (wasMapped && !pWin->mapped) - { - Bool overrideRedirect = pWin->overrideRedirect; - pWin->overrideRedirect = TRUE; - DisableMapUnmapEvents (pWin); - MapWindow (pWin, clients[CLIENT_ID(id)]); - EnableMapUnmapEvents (pWin); - pWin->overrideRedirect = overrideRedirect; - } + + if (anyMarked) + compHandleMarkedWindows (pWin, pLayerWin); } /* -- 1.7.3.4 _______________________________________________ [email protected]: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: http://lists.x.org/mailman/listinfo/xorg-devel
