* | Increase range of ComparingUpdateTracker statisticsPierre Ossman2018-11-301-1/+1
| | | | | | | | | | | | 32 bits are not enough to keep track of all the pixels that might flow through the system. Expand things to 64 bits, which should cover all reasonable uses.
* | Abort unsafe lossless refresh earlyPierre Ossman2018-11-231-13/+15
| | | | | | | | | | | | | | We need to check earlier if we are going to send this refresh or not. Otherwise we send out pings pointlessly, and we also stall the request loop with a client as we clear the requested region without actually sending an update message.
* | Move lossless refresh handling to separate methodPierre Ossman2018-11-232-45/+79
| | | | | | | | | | It makes the logic a bit easier to follow, and also fixes the case where just a fake update is needed.
* | Fix bad size check in Tight decoderPierre Ossman2018-11-231-1/+1
| | | | | | | | Fallout from beb59a43.
* | Use larger integers for the cursor ditheringPierre Ossman2018-11-231-6/+6
| | | | | | | | | | We need a larger range to handle the temporary overflow caused by the Floyd-Steinberg dithering.

| * | Remove variable length arraysPierre Ossman2018-11-073-29/+31
| |/ | | | | | | | | These are not allowed in C++, and have been made optional in C11. So let's just get rid of them and any issues they may cause.

| * | | Get rid of SocketServer::checkTimeouts()Pierre Ossman2018-11-093-23/+0
| | | | | | | | | | | | | | | | | | | | | | | | It doesn't belong on each socket server object as timers are global. Force implementations to call the Timer system directly instead, avoiding any middle men.
| * | | Change idle timeout to timerPierre Ossman2018-11-093-50/+25
| | | | | | | | | | | | | | | | | | | | Get this timeout in to the timer system as well to make things simpler and more robust.
| * | | Properly terminate server on timeoutsPierre Ossman2018-11-092-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | Do a proper cleanup when one of the termination timeouts trigger rather than just exiting on the spot. This makes sure we don't leave stray stuff around, e.g. unix socket files.
| * | | Change exit timeouts to timersPierre Ossman2018-11-092-79/+32
| | | | | | | | | | | | | | | | | | | | | | | | This makes them more consistent with everything else, which makes things clearer and also allows them to handle some corner cases (e.g. only firing once).

| * | Clean up headersPierre Ossman2018-11-092-10/+17
| | | | | | | | | | | | Add missing comments and clearly separate methods from attributes.
| * | Remove unused functions from server classesPierre Ossman2018-11-092-11/+0
| | |
| * | Make throwConnFailedException() protectedPierre Ossman2018-11-091-5/+5
| | | | | | | | | | | | | | | It is an internal function so it has no business being public. Compare with CConnection where it is already private.
| * | Remove writeConnFailedFromScratch()Pierre Ossman2018-11-093-18/+7
| | | | | | | | | | | | It is static and only used from a single place, so let's inline it.
| * | Remove comments about self-deleting connectionsPierre Ossman2018-11-091-9/+2
| | | | | | | | | | | | It isn't true so remove those comments.
| * | Move ListConnInfo to WinVNC directoryPierre Ossman2018-11-096-221/+2
| | | | | | | | | | | | | | | It is functionality specific to WinVNC, so move the code there to make things more clear.
| * | Inherit SocketServer directly from VNCServerPierre Ossman2018-10-262-6/+5
| | | | | | | | | | | | | | | | | | | | | This makes VNCServer a sufficiently complete interface that callers don't need to know about the specific implementation (VNCServerST currently). And assuming that all servers will use sockets is not that outrageous.
| * | Encapsulate client handling in VNCServerSTPierre Ossman2018-10-263-70/+95
| | | | | | | | | | | | | | | | | | Removed the last parts of VNCSConnectionST's back door in to VNCServerST and let the parent class fully handle coordination of clients, and access to the desktop.
| * | Move access rights and closing to SConnection objectPierre Ossman2018-10-107-52/+88
| | | | | | | | | | | | | | | This makes it generally useful and other code doesn't have to know of the specific sub-class.
| * | Encapsulate setDesktopSize() in VNCServerSTPierre Ossman2018-10-103-32/+38
| | | | | | | | | | | | | | | More encapsulation of functions that require coordinate between clients.
| * | Encapsulate event handling in VNCServerSTPierre Ossman2018-10-103-36/+66
| | | | | | | | | | | | | | | | | | There is some client coordination needed which is better encapsulated inside VNCServerST. This also helps hiding the desktop from the individual clients.
| * | Use accessor methods for VNCServerSTPierre Ossman2018-10-103-34/+35
| | | | | | | | | | | | | | | Avoid having VNCSConnectionST poking around in VNCServerST's internals and instead access things via safer methods.
| * | Remove QueryConnectionHandlerPierre Ossman2018-10-105-40/+42
| | | | | | | | | | | | | | | Make things simpler by making this a part of the SDesktop interface that always needs to be implemented.
| * | Force common flow of connection queriesPierre Ossman2018-10-093-33/+12
| | | | | | | | | | | | | | | | | | Force queryConnection() to always call back to approveConnection() rather than return special values. This makes the flow easier to follow as it will be the same in all cases.

* / Log TLS handshake resultPierre Ossman2018-10-092-1/+5
|/ | | | | Makes it easier to debug TLS issues, and to see the effect of altering the priority string.
* Restore original streams when terminating TLSPierre Ossman2018-09-214-2/+27
| | | | | | In theory we could return to communicate without TLS after a shutdown. It also makes sure the connection object isn't left completely without streams.
* Delete TLS streams before deleting the sessionPierre Ossman2018-09-214-33/+40
| | | | | | The streams depend on the session and can crash the program if they are removed in the wrong order. Do a general cleanup of the life time management of the streams.
* Strongly bind security objects to connection objectPierre Ossman2018-09-2130-93/+123
| | | | | There is already an implicit connection between them, so let's make it explicit. This allows easy lookup outside of the processMsg() function.
* Initialise CSecurityTLS::cert_cred properlyPierre Ossman2018-09-211-1/+1
| | | | | If we leave it at something random we'll get an invalid delete if the handshake fails.
* Remove destroy functionsPierre Ossman2018-09-214-4/+4
| | | | | These are just confusing and obfuscating. Do a normal delete of these objects instead.
* Estimate higher bandwidth in slow startPierre Ossman2018-09-211-2/+11
| | | | | | | If we are still in slow start then we haven't discovered the actual bandwidth limit yet. We also rely on the caller causing a bit of congestion to detect the limit. So report a higher bandwidth estimate than what we've currently tested in this scenario.
* Allow perceptually lossless refreshPierre Ossman2018-09-214-12/+36
| | | | | | | | | | | Loosen the definition of "lossless" a bit so that we can use high quality JPEG to refresh damaged parts of the screen. Although this isn't bit perfect, it is close enough that most users will not be able to tell the difference. Level 9 is used rather than level 8 because some monitors have exaggerated contrast that allows the artefacts from level 8 to be noticeable.
* Add method to get compression settings from encoderPierre Ossman2018-09-203-0/+10
|
* Don't force encoders to specify palette sizePierre Ossman2018-09-205-5/+5
| | | | | Most encoders don't have a palette mode, so don't force them to specify a dummy value to the Encoder base class constructor.
* Limit maximum lossless refresh CPU usagePierre Ossman2018-09-201-2/+7
| | | | | | If we have plenty of bandwidth then CPU might be the limiting resource. Unfortunately we don't have a good number for that limit, so add a conservative hard coded value.
* Don't attempt to send empty lossless refreshPierre Ossman2018-09-201-6/+9
| | | | | If we're out of time then we will definitely overshoot, so don't even try.
* Fix calculation of maximum lossless refresh areaPierre Ossman2018-09-201-0/+3
| | | | | The update size is in bytes, but we are counting pixels. So make sure we convert things properly before comparing.
* Avoid refresh of recently changed areasPeter Åstrand (astrand)2018-09-204-11/+80
| | | | | | | | If an area recently changed then we can guess that it will most likely change again very soon. In such a case it is meaningless to send a lossless refresh as it will directly be overwritten. Keep track of such areas and avoid refreshing them until we no longer see any changes to them.
* Fix bad reference in Timer::getRemainingMs()Pierre Ossman2018-09-201-1/+1
| | | | | The reference for "dueTime" wasn't properly updated when this code was refactored from a static method to a normal object method.
