In one possible implementation, after the data analysis service is started, the definition information is obtained by first reading and parsing wayland the protocol definition file through the definition sub-service. The definition information in wayland protocol definition file defines the resolution mode of the original data/original communication data of the protocol.
The specific content of the wayland protocol definition file is not limited, and can load wayland original protocol definition and wayland extension protocol definition.
After receiving or reading the original data file, the display sub-service analyzes the original protocol data/original communication data through the received and/or read wayland protocol definition to obtain visual data, and then displays the visual data.

Step S220 obtains the original communication data in the communication link. After anchoring (hook) the corresponding Unix Domain Socket/communication link, the invention obtains Unix Domain Socket/protocol data/raw communication data in the communication link.
Step S230 processes the original communication data based on the definition information to obtain at least one visual data. The invention can process the protocol data/original communication data according to the definition information through the data analysis service to obtain corresponding visual data. When there are a plurality of windows, the visualized data is also correspondingly a plurality of windows.

The window plug-in for wayland protocol analysis is represented by the dashed rectangle in fig. 3, divided into two parts. Part is ebpf programs, which need to be dynamically loaded into the linux kernel and run KERNEL SPACE. Attached to Unix Domain Socket (inter-process communication) connections of the windowing system, protocol data is collected. And the other part of time data analysis service is responsible for receiving protocol data from ebpf programs, analyzing raw data (original communication data) into a human recognizable representation form according to wayland protocol, and displaying the representation visually.

The existing data acquisition applied to wayland protocols has the following several ways:
The WAYLAND_DEBUG environment variable, which is set before client or server is started, can print window protocols to standard output.
Wayland-tracker. Protocol data can be recorded by using the tracker to start clients, and if a protocol xml file exists, the protocol can be parsed.
Wlan sizer/wldump, start client with wldump to record protocol data into file, wlanalyzer parse file recording protocol data, also can pass protocol data from wldump to wlanalyzer to parse in real time by IPC.
Wtdbg hijacking wayland socket connection, debugging the protocol like gdb debugger.
The above formulas can only be used for starting clients to print or debug, and for the running wayland window system, the direct attach capability is not provided, and the protocol service condition of the running system can not be observed and analyzed.
To summarize, modes 1 to 4 cannot collect original communication data for an established communication link between a window manager and an application window established based on wayland protocol.
According to the technical scheme, ebpf programs can be dynamically loaded into the linux kernel, the analyzed window system client and server do not need to be modified, and the client or server does not need to be restarted.
