API breaking change, with this logic the symbol needs to be manually
defined by an API user. So, to fix this:
* Rename to DROP_FREERDP_3x_DEPRECATED
* Invert logic, so a undefined value enables the symbols
This new CMake option (ON by default) allows building the library with
all symbols deprecated during 3.x release cycle disabled.
This allows compatibility testing external applications for future
FreeRDP 4.x support
the function uses implicit color formats. Replace this with the function
shadow_subsystem_pointer_convert_alpha_pointer_data_to_format with
explicit source color format.
Deprecate the old function.
shadow_capture_compare_with_format and shadow_capture_compare always
operate on distinct memory areas. Allow better optimization of
operations with the WINPR_RESTRICT keyword
Implement a (optional) peer limitation check for shadow server.
with the command line option /max-connections:<number> the maximum
number of simultaneous connections can be limited.
The current server side channel handling of AUDIO_INPUT is currently
very constrained:
- Server implementations cannot measure the clients uplink, since the
Incoming Data PDU is currently unhandled and FreeRDPs DSP handling
delays the callback call of ReceiveSamples
- Servers currently cannot prefer a different protocol version
- Servers currently cannot change the used format
To solve these issues without running into the risk that some
simplifications constraint certain API usage, rework the current channel
handling to be very close to the documentation.
This means, that all documented API calls can be made by server
implementations and all documented PDUs, that the server side is
expected to receive are just parsed inside FreeRDP and then forwarded to
the API implementation.
The shadow server tries to resize the client to use a compatible
resolution. If that fails, e.g. if there is another resize request after
the disconnect/reconnect sequence, abort the connection.
* Fixed GetFileInformationByHandle initializers
* Fix#7793: Do not expose internal input API
Slow-Path input uses UINT16 for scancodes on wire, but only the
lower byte is actually used. (the extended fields are sent in
keyboardFlags field)
Hide this implementation detail and adjust the API to use UINT8
for the code instead just like the corresponding Fast-Path PDU
* Added a warning for problematic slow path keyCodes
It will be completely possible to implement subsystem with only include/freerdp/server/shadow.h and libfreerdp-shadow.
Details as following:
1. Exported surface structure as subsystem implementations deeply depend on it to send image update
2. Export capture APIs. They are actually indepent APIs to help compare and calculate image difference.
3. Introduce API to trigger client frame update. Conceal details in subsystem->updateEvent
4. Pass client to client callbacks. Subsystem implementation may need to know 'which client' send the interaction event as well as the authentication request.
Add this support in callback definition before anyone really use shadow framework APIs to implement a custom subsystem.
Also added callback for client capability exchange
5. Remove X11_ShadowSubsystem Mac_ShadowSubsystem Win_ShadowSubsystem from libfreerdp-shadow.
Discard FREERDP_API mark on ShadowSubsystemEntry functions and make them be compiled together with shadow.c in CMakeLists.txt.
This is required from PR #2751.
Now subsystem implementations and shadow.c could be regarded as an example for shadow framework.
Detail fixes:
1. Add resize support in shadow framework layer
2. Enhance X11 implementation to detect desktop resolution change
3. Fix the subRect feature.
It seems not completely finished and it looks incompatible in different source code.
Fix it to be consistent in all source code as following:
a. The subRect is only awared in framework layer, subsystem implementation should not be aware of it. It only take effect at shadow_client and corresponding shadow_input.
b. The screen and surface should only represent a monitor screen. They don't need to consider subRect feature.
4. A lobby should be alternative image shown to client when the client is not 'mayView'.
We don't need to have seperate lobby for each client, move it into server structure as 'another surface'
5. Fix display handle leak in enum monitor of X11
6. Suppress BadMatch Error while capturing the image
