* | Clipboard.c: limit selection nxagentFindCurrentSelectionIndex can return | Ulrich Sibiller | 2021-06-20 | 1 | -1/+15 |
| | | | | | | | | | | | | | | | | | Normally you'd expect the loop going up to NumCurrentSelections. But the dix code will increase that number (but not nxagentMaxSelections) when drag and drop comes into play. In that case this helper will report a match for other selections than the ones the clipboard code knows about. The subsequent code will then use a higher index which will lead to out of range data reads (and writes!). Therefore we take nxagentMaxSelections here. The startup code ensures that both arrays will refer to the same selection for the first nxagentMaxSelections selection atoms. This way the clipboard code will not kick in for drag and drop resources. Fixes ArcticaProject/nx-libs#986 | ||||
* | Clipboard.c: rework nxagentFind*SelectionIndex() helpers | Ulrich Sibiller | 2021-06-20 | 3 | -14/+16 |
| | | | | Let them return -1 which makes it easier to check for successful execution. | ||||

* | Clipboard.c: extend target caching for the other direction | Ulrich Sibiller | 2021-06-20 | 1 | -17/+76 |
| | | | | | | | | | | This may seem unneccessary at first sight because we are only talking to our own clients which generally is quick. But if you are using nested nx sessions or clients from remote machines (e.g. via ssh X forwarding) this still can save some lenghty communication. Plus: it helps in debugging because there are fewer messages being sent around. | ||||

* | Clipboard.c: implement target caching | Ulrich Sibiller | 2021-06-20 | 1 | -0/+118 |
| | | | | | | | | | | | | | | | | | | | | | | Some applications (e.g. Chrome, Firefox) send multiple TARGETS requests when they want to paste a selection (reason currently unknown). If such an application runs in an NX session and the current clipboard owner is on the real X server this triggers many (superflous) roundtrips. By caching the first answer to those requests and answering subsequent requests from the cache we can eliminate all this communication. The implemention resulted from attempting to fix ArcticaProject/nx-libs/issues/#969 (solution 1a) but it turned out that the speedup this brings does not help in reducing the number of requests by firefox. It must be a bug in the firefox code. Nevertheless I kept the code as it should speed up the whole pasting process considerably while reducing communication over the wire. This also eliminates a memory leak in the target forwarding code which was unnoticed before. | ||||

* | Clipboard.c: once again improved DEBUG output | Ulrich Sibiller | 2021-06-20 | 1 | -13/+34 |
| | | | | | | | | Also reduce number of certain DEBUG lines: These PropertyEvents tend to appear quite often and most of the times they have nothing to do with the clipboard. So instead of printing them everytime we turn that around and print something only if it is a clipboard related event.. | ||||
* | Clipboard.c: fix: remove wrong optimization | Ulrich Sibiller | 2021-06-20 | 1 | -14/+4 |
| | | | | | | | | | | In the "none" case we must ensure the clipboard data is reset. This "optimization" skipped the reset part which made the code think it is waiting for an answer. Which (of course) never arrived. So any further request was rejected... Also reduce debugging output for the "none" case because resetClientSelectionStage will print it anyway. | ||||
