* Remove unneeded CharArray:sPierre Ossman2023-02-042-10/+9
| | | | | Avoid complicating things by moving things in to a second buffer here as there is no need for it.
* Use StringParameters directlyPierre Ossman2023-02-041-9/+7
| | | | | We don't need to make extra copies of the string in most cases, so let's simplify the code and access the string directly when we can.
* Get rid of TCHAR magicPierre Ossman2023-02-0442-486/+254
| | | | | We never use Windows' "UNICODE" mode anyway, so let's get rid of this complexity.
* Return std::vector instead of dynamic allocationPierre Ossman2023-02-042-15/+9
| | | | | This makes memory management more clear and robust when using these helper functions.
* Move hex conversion helpers to utilPierre Ossman2023-02-042-5/+7
| | | | | These are used here and there so let's make them more general rather than hiding them in the stream classes.
* Use std::vector for basic data arraysPierre Ossman2023-02-013-30/+31
| | | | | Avoid our own custom types in favour of what's already included with C++.
* Use stdint typesPierre Ossman2023-02-0111-41/+42
| | | | | Avoid having our own custom stuff and instead use the modern, standard types, for familiarity.
* Work around -Wcast-function-typePierre Ossman2023-01-051-9/+9
| | | | | That warning doesn't play well with Windows' GetProcAddress(), so add some extra casting to work around it.
* Fix incorrect typesPierre Ossman2023-01-051-1/+1
| | | | | These types caused an incorrect signed/unsigned behaviour, so let's make sure we use the appropriate type.
* Remove useless checksPierre Ossman2023-01-051-1/+1
| | | | These are all truisms because of the valid range of the types.
* Explicitly mark unused parametersPierre Ossman2023-01-045-7/+8
| | | | | This allows us to separate accidentally unused, from explicitly unused parameters, which allows us to turn on such checks in the compiler.
* Avoid temporary cmake variablesPierre Ossman2022-06-071-4/+2
| | | | | Modern cmake has better support for adding source files and libraries incrementally, so let's use that to clean things up.
* Be consistent in including config.hPierre Ossman2021-12-3031-0/+123
| | | | | | The generally recommended way is to include it from source files, not headers. We had a mix of both. Let's try to be consistent and follow the recommended way.
* Add support for notifying clients about pointer movementslhchavez2021-03-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | This change adds support for the VMware Mouse Position pseudo-encoding[1], which is used to notify VNC clients when X11 clients call `XWarpPointer()`[2]. This function is called by SDL (and other similar libraries) when they detect that the server does not support native relative motion, like some RFB clients. With this, RFB clients can choose to adjust the local cursor position under certain circumstances to match what the server has set. For instance, if pointer lock has been enabled on the client's machine and the cursor is not being drawn locally, the local position of the cursor is irrelevant, so the RFB client can use what the server sends as the canonical absolute position of the cursor. This ultimately enables the possibility of games (especially FPS games) to behave how users expect (if the clients implement the corresponding change). Part of: #619 1: https://github.com/rfbproto/rfbproto/blob/master/rfbproto.rst#vmware-cursor-position-pseudo-encoding 2: https://tronche.com/gui/x/xlib/input/XWarpPointer.html 3: https://hg.libsdl.org/SDL/file/28e3b60e2131/src/events/SDL_mouse.c#l804

| * Change streams to be asynchronousPierre Ossman2020-05-211-5/+32
| | | | | | | | | | | | | | | | | | | | Major restructuring of how streams work. Neither input nor output streams are now blocking. This avoids stalling the rest of the client or server when a peer is slow or unresponsive. Note that this puts an extra burden on users of streams to make sure they are allowed to do their work once the underlying transports are ready (e.g. monitoring fds).
* | Don't clear complex objects using memset()Pierre Ossman2020-05-312-4/+2
|/ | | | This is fine for simple structs but not class based objects.
* Clean up initialization of DIBSectionBufferPierre Ossman2020-01-034-35/+8
| | | | | | We had an unintentional conflict with PixelBuffer::setSize() here. But we can simplify this further as this initialization is only used by the subclass DeviceFrameBuffer, and only once.
* Use size_t for lengths in stream objectsPierre Ossman2019-11-152-6/+6
| | | | | | | | Provides safety against them accidentally becoming negative because of bugs in the calculations. Also does the same to CharArray and friends as they were strongly connection to the stream objects.
* Encapsulate PixelBuffer internal detailsPierre Ossman2019-11-151-25/+16
| | | | | | Don't allow subclasses to just override dimensions or buffer details directly and instead force them to go via methods. This allows us to do sanity checks on the new values and catch bugs and attacks.
* Use display polling by default in WinVNCPierre Ossman2019-09-061-1/+1
| | | | | Window hooks aren't working well on modern systems so switch the default to polling until we can fix things.
* Use UTF-8 in clipboard APIPierre Ossman2019-07-011-54/+19
| | | | | In prepartion for better clipboard extensions that can send Unicode data between the client and server.
* Improved clipboard APIPierre Ossman2019-07-014-36/+65
| | | | | Change the internal clipboard API to use a request based model in order to be prepared for more advanced clipboard transfers.
* Clean up internal clipboard handlingPierre Ossman2019-07-014-12/+12
| | | | | | We now filter incoming data, which means we can start assuming the clipboard data is always null terminated. This allows us to clean up a lot of the internal handling.
* Make sure clipboard uses \n line endingsPierre Ossman2019-07-011-14/+2
| | | | | | This is required by the protocol so we should make sure it is enforced. We are tolerant of clients that violate this though and convert incoming clipboard data.
* Add missing throws for exceptionPierre Ossman2019-03-261-1/+1
| | | | | It is not enough to create an exception object, you need to throw it as well.
* Get rid of SocketServer::checkTimeouts()Pierre Ossman2018-11-091-1/+2
| | | | | | 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.
* Properly terminate server on timeoutsPierre Ossman2018-11-092-0/+10
| | | | | | 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.
* Move ListConnInfo to WinVNC directoryPierre Ossman2018-11-092-1/+32
| | | | | It is functionality specific to WinVNC, so move the code there to make things more clear.
* Remove QueryConnectionHandlerPierre Ossman2018-10-102-1/+35
| | | | | Make things simpler by making this a part of the SDesktop interface that always needs to be implemented.
* Remove Java web serverPierre Ossman2018-10-092-21/+0
| | | | | Applets don't work anymore so remove everything that has to do with serving them.
* Interpret Meta as AltPierre Ossman2018-09-211-0/+2
| | | | | Shift+Alt often generates Meta on Unix systems. Assume this is the same thing as Alt on Windows.
* Catch exceptions by referencePierre Ossman2018-05-292-5/+5
| | | | | We use polymorphic exception objects, so catching by value invokes the copy constructor and stuff that we don't really want.
* Stop using CopyRect in WinVNCPierre Ossman2017-11-241-5/+5
| | | | | | It cannot keep itself in sync with the actual screen contents well enough for CopyRect to work accurately. Graphical glitches could be seen in some cases.

| * Handle Ctrl+Alt+Delete in raw keyboard modePierre Ossman2017-11-131-0/+8
| | | | | | | | | | Ctrl+Alt+Delete requires special handling to trigger on Windows. Make sure this works in raw keyboard mode as well.
| * Handle Windows scan code exceptionsPierre Ossman2017-11-131-0/+23
| | | | | | | | | | Windows mostly follows the AT set 1 scan codes that we want, but there are a few exceptions.

* Get rid of getFbSize()/getDesktopSize() in commonPierre Ossman2017-09-221-1/+4
| | | | It was only used by WinVNC, so push it there instead.
* rfb_win32: Use scan codes if availableRahul Kale2017-09-112-0/+36
| | | | | | | | | | | If scan codes are available using QEMU Extended Keyboard Messages from clients, use that to inject scancodes directly into the system using the SendInput API. No conversion is needed as Windows uses the same scancode encoding. Signed-off-by: Rahul Kale <Rahul.Kale@barco.com> Signed-off-by: Peter Korsgaard <peter.korsgaard@barco.com>
* Basic support for QEMU Extended Key EventsPierre Ossman2017-08-284-5/+5
| | | | | | This adds the basic infrastructure and handshake for the QEMU Extended Key Events extension. No viewer or server makes use of the extra functionality yet though.
* rfb_win32: Add support for LED state notificationsRahul Kale2017-08-282-1/+31
| | | | | | | | | | LED support added using Windows GetKeyState() API call. The state is polled for change in CapsLock/NumLock/ScrollLock status in the same code block where chages to Cursor shape is polled.

* Change cursor API to use RGBA dataPierre Ossman2017-02-222-86/+153
| | | | | This will allow us to use better formats that preserve the entire alpha channel.

* Replace Windows specific thread handlingPierre Ossman2016-07-079-346/+45
| | | | Use the platform independent primitives instead.
* Move socket write event handling in to the RFB corePierre Ossman2016-04-291-1/+1
| | | | | | What to do when a socket is writeable should be handled in the RFB core code as there may be other events we want to fire off when this happens.
* Remove legacy Windows codePierre Ossman2016-01-1223-1040/+264
| | | | | We have lots of code that deals with Windows versions that we no longer support anyway. Clean out all of this old cruft.
* Remove stub mirror driver codePierre Ossman2016-01-123-62/+2
| | | | | We don't have any meaningful code for the mirror driver, so remove the confusing stub and interface for it.
* Provide description for servicesPierre Ossman2016-01-122-4/+11
| | | | | | The argument named "desc" was not actually the description, but rather the short "display name". Add handling for the actual description to reduce confusion.
* Use correct type for format stringPierre Ossman2015-09-291-1/+3
