| | | | | | | | | | | | | | | | | | commit 312910b4e34215aaa50fc0c6092684d5878dc32f Author: Chase Douglas <chase.douglas@canonical.com> Date: Wed Apr 18 11:15:40 2012 -0700 Update currentTime in dispatch loop A request, like input device grabs, may check a request timestamp against currentTime. It is possible for currentTime to lag a previously sent event timestamp. If the client makes a request based on such an event timestamp, the request may fail the validity check against currentTime unless we always update the time before processing the request.

* nxagent: drop nxagentRootTileWindowUlrich Sibiller2019-08-271-2/+0
| | | | | | | | We either use a solid black or a white background and no backround pixmap. So nxagentRootTileWindow is always empty and we can drop all stuff around it. remove nxagentSplashCount, too, since it is no longer checked anywhere.
* rework xkb device private handlingUlrich Sibiller2019-06-221-0/+9
| | | | | | | We can only free the xkbDevicePrivate because we do not know the details of any other (possible) extension. So let's limit to that one private for now and call the new xkbFreePrivates from dix (where such a function is completely missing).

* CloseDevice: call XkbRemoveResourceClient before freeing key class structUlrich Sibiller2019-06-191-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | This patch is not necessary at the current code level. But when xkb code introduced the dev->key check Xorg upstream missed that. So we backport it now to skip that trap when updating xkb code. Author: Alan Coopersmith <alan.coopersmith@sun.com> Date: Mon Jan 4 18:21:54 2010 -0800 CloseDevice: call XkbRemoveResourceClient before freeing key class struct XkbRemoveResourceClient() returns immediately if dev->key is NULL. CloseDevice calls XkbRemoveResourceClient until it removes all resources. If we free dev->key and NULL it before XkbRemoveResourceClient, then infinite loop ensues, and the server appears to hang on exit or crash.

* Fix NXevents.c: Reactivate errornously commented functionUlrich Sibiller2019-06-111-0/+4
| | | | | | | | | CheckMotion() had been commented in add881931f2e702fb1952f4e1baba04b3dc536ee as it looked identical to the version from dix/events.c except for some commented code. But this based (probably) on a thinko - code that had been disabled by NX became active again this way. Fix this by removing the comments and by adding #ifdef/else to emphasize the difference.

This leads to weird behaviour for extensions that truly require running under the same OS services as the client, like MIT-SHM and DRI2. Add two new legal values for the initial connection's byteOrder field, 'r' and 'R'. These act like 'l' and 'B' respectively, but have the side effect of forcing the client to be treated as non-local. Forwarding proxies should attempt to munge the first packet of the connection accordingly; older servers will reject connections thusly munged, so the proxy should fall back to passthrough if the munged connection attempt fails.
