Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 is a schematic flowchart of an applet simulation method according to an embodiment of the present application. The method and the device can be applied to the situation that the operation effect of the small program is simulated through the simulator in the small program development tool in the small program development process. The applet simulation method disclosed in this embodiment may be executed by an electronic device, and specifically may be executed by an applet simulation apparatus, which may be implemented by software and/or hardware and configured in the electronic device. Referring to fig. 1, the applet simulation method provided in this embodiment includes:
and S110, under the condition of updating the small program, the simulator main process sends a reloading instruction to the simulator working thread.
And S120, reloading the simulator working thread to obtain updated applet data, and sending the updated applet data to the simulator main process.
And S130, simulating the small program to run by the simulator main process according to the updated small program data.
The simulator main process is an execution entity of simulator codes in the small program development tool. The applet development tool includes a compiler process, a debugger process, a rendering process, etc., in addition to the simulator main process. In the applet simulation process, the applet code may need to be updated. In the small program simulation process, a small program developer (namely, a small program research and development worker) modifies a small program code, stores a modified small program file, compiles and debugs the modified small program file through a compiling process and a debugging process in a small program development tool, informs a rendering process after compiling and debugging are completed, informs a simulator main process of the rendering process, and sends a reloading instruction to a simulator working thread after the simulator main process receives the notice. Specifically, the rendering process may send a refresh notification message to the simulator host process, and the simulator host process may send a reload instruction to the simulator worker thread after receiving the refresh notification message.
The simulator working thread responds to the reloading instruction, reloading, namely killing (kill) and restarting is carried out, updated small program data are obtained in the restarting process, the simulator working thread is further interacted with the simulator main process, the updated small program data are sent to the simulator main process, and the simulator main process simulates the small program running process according to the updated small program data. Wherein the updated applet data is determined from the modified applet file.
In the embodiment of the application, a main process (master) and a working thread (worker) are matched and introduced into an applet development tool, a simulator working thread is used as an inlet of a simulator main process, under the condition of applet updating, the simulator working thread is reloaded to obtain updated applet data, and the simulator main process receives the updated applet data from the simulator working thread and simulates applet running according to the updated applet data. In other words, in the applet updating process, the simulator working thread is only required to be reloaded, the simulator main process is not required to be reloaded, and the applet refreshing efficiency in the applet simulating process can be improved, so that the applet simulating efficiency and the applet developing efficiency can be improved. In addition, the reloading speed of the simulator working thread is far higher than the speed of refreshing the webview (webpage view), so that the small program refreshing speed can be improved compared with the method of directly loading the simulator main process through the webview in a cross-platform desktop application program (electronic).
According to the technical scheme, the simulator working thread is introduced to serve as the entrance of the simulator main process, under the condition of small program updating, the simulator working thread only needs to be reloaded, the simulator working thread interacts with the simulator main process, updated small program data are transmitted to the simulator main process, the simulator main process simulates according to the updated small program data, small program updating efficiency in the simulation process is improved, and therefore small program development efficiency is improved.
Fig. 2 is a schematic flowchart of an applet simulation method according to an embodiment of the present application. The present embodiment is an alternative proposed on the basis of the above-described embodiments. Referring to fig. 2, the applet simulation method provided in this embodiment includes:
s210, under the condition of updating the small program, the simulator main process sends a reloading instruction to the simulator working thread.
S220, reloading the simulator working thread to obtain updated applet data, and sending the updated applet data to the simulator main process.
And S230, the simulator main process responds to the function call instruction sent by the simulator working thread according to the updated applet data, executes the function to be called to obtain an execution result, and writes the execution result into the shared memory.
S240, the simulator working thread waits when detecting that the execution result in the shared memory is not written into.
And S250, when the simulator main process detects that the execution result in the shared memory is written in, waking up the simulator working thread, and reading the execution result from the shared memory by the simulator working thread.
The host process and the worker thread in worker thread mode generally do not support synchronous communication. The embodiment of the application can support synchronous communication of the working threads by matching the shared memory with the atomic operation. The calling party is in the simulator working thread and is realized by the simulator main process. The simulator working thread can send a function calling instruction to the simulator main process according to the updated applet data, wherein the function calling instruction at least comprises a function identifier to be called and a function parameter, the simulator main process responds to the function calling instruction to execute the function to be called to obtain an execution result, and the execution result is written into the shared memory.
After the simulator worker thread sends the function call instruction, whether the execution result in the shared memory is written in is detected, and under the condition that the writing is not finished, the simulator worker thread can enter a waiting state through an atomic waiting lock such as atomic. In the waiting process of the working thread of the simulator, when detecting that the execution result in the shared memory is written, the main process of the simulator can wake up the working thread of the simulator through atomic wake up such as atomic wake (), and the working thread of the simulator reads the execution result from the shared memory after waking up.
In the view of the main process of the simulator, the function calling communication process belongs to asynchronous communication, and because the middle of the working thread of the simulator is in a waiting state, the event loop (event loop) of the working thread of the simulator is not updated to the next round, and the execution stack is not executed completely until the working thread of the simulator is awakened by the main process of the simulator, namely, in the view of the working thread of the simulator, the function calling communication process belongs to synchronous communication. And because the simulator working thread enters a waiting state under the condition that the execution result in the shared memory is not written into the shared memory, and then the simulator main process wakes up the simulator working thread under the condition that the simulator main process detects that the execution result in the shared memory is written into the shared memory, deadlock abnormity caused by the fact that the simulator working thread enters the waiting state after receiving atomic wake-up can be avoided.
In an alternative embodiment, the simulator main process simulating the applet running according to the updated applet data comprises the following steps: the simulator main process responds to a function call instruction sent by the simulator working thread according to the updated applet data, executes the function to be called to obtain an execution result, and writes the execution result into the shared memory; and the simulator working thread reads the execution result from the shared memory when detecting that the execution result in the shared memory is written into the shared memory.
Specifically, after sending a function call instruction to the simulator main process, the simulator working thread detects whether the execution result in the shared memory is written in, and under the condition that the writing is finished, the simulator working thread does not need to enter a waiting state, and the execution result is directly read from the shared memory. Before the simulator working thread enters the waiting state, if the execution result in the shared memory is written into the simulator working thread, the simulator working thread does not need to enter the waiting state, so that deadlock abnormity can be avoided, and the working efficiency of the simulator working thread can be improved.
It should be noted that, in the synchronous communication process, when the length of the data to be transmitted exceeds the capacity of the shared memory, the data may be sent in segments, so as to avoid the synchronous communication process being restricted by the capacity of the shared memory. The number of the fragments can be determined according to the length of the data to be transmitted and the capacity of the shared memory.
It should be noted that, since the main process and the worker thread in the worker thread mode can generally support asynchronous communication, the applet to be simulated can also call an asynchronous communication function. Specifically, in the process of calling the asynchronous communication function, the simulator working thread can send an asynchronous function calling instruction to the simulator main process according to the updated applet data and process a message returned from the simulator main process; the simulator main process monitors a function call instruction sent by the simulator working thread, executes a function to be called to obtain an execution result, and sends the execution result to the simulator working thread.
In an optional implementation manner, after writing the execution result to the shared memory, the method further includes: the simulator main process writes a wake-up identifier into the shared memory; the wake-up identifier is used for representing whether the execution result in the shared memory is written in. By writing the wake-up flag into the shared memory, the simulator can conveniently detect the work of the simulator to determine whether the execution result in the shared memory is written into.
In an optional implementation manner, the function call instruction includes a function call identifier, and the function call identifier is unique and is used to write the function call identifier into the shared memory as the wake-up identifier. Specifically, after the execution result is written into the shared memory by the main process of the simulator, the unique function call identifier in the function call instruction is written into the shared memory as the wake-up identifier, so that the simulator can conveniently detect the work to determine whether the execution result in the shared memory is written into the shared memory.
In addition, in order to control the state of the worker thread, the state control information of the worker thread may also be written into the shared memory, such as a wait state atomic.
According to the technical scheme, synchronous communication of the simulator working threads can be supported through cooperation of the shared memory and atomic operation, the simulator working threads are not waited until the simulator main detection successfully writes the execution result into the shared memory after detection that the execution result in the shared memory is not written into the shared memory, and deadlock abnormity in the synchronous communication process can be avoided.
Fig. 3 is a schematic flowchart of an applet simulation method according to an embodiment of the present application. The present embodiment is an alternative proposed on the basis of the above-described embodiments. Referring to fig. 3, the applet simulation method provided in this embodiment includes:
s301, under the condition of updating the small program, the simulator main process sends a reloading instruction to the simulator working thread.
S302, reloading the simulator working thread to obtain updated applet data, and sending the updated applet data to the simulator main process.
Specifically, the rendering process may notify the simulator via the simulator host process that the worker thread reloads. After the rendering process monitors that the simulator working thread is reloaded, a small program completion preparation message can be sent to the simulator working thread through the simulator main process, a page preparation message can also be sent to a slave process (slave process) of the main process of the small program development tool by the rendering process, after the slave process is prepared, the slave process preparation completion message is sent to the simulator main process by the rendering process, and after the simulator main process monitors the message, the slave process interacts with the simulator working thread to obtain updated small program data.
And S303, updating the applet page by the simulator main process through the rendering process according to the updated applet data.
Specifically, the simulator main process also sends the updated applet data to the rendering process, the rendering process sends the updated applet data to the slave process, and the slave process renders the applet page according to the updated applet data. In the updating process of the small program, the refreshing efficiency of the small program page can be improved only by reloading the working thread of the simulator.
In an alternative embodiment, the method further comprises: in the starting process of the simulator, the simulator main process also preloads an applet interface for the applet to be simulated, so that the development efficiency of the applet is improved. The applet interface refers to an applet interface provided by an applet development tool in advance, and may include at least one of the following: the system comprises a base, a route, a network, an interface, a data store, an Artificial Intelligence (AI), media, a location, a canvas, a device, a third party platform, an open interface, a user interface, a server interface, a promotion interface, and the like.
The small program interface (simulation API) is placed in a simulator main process, the small program to be simulated calls the small program interface through the simulator main process, and a simulator working thread is independent of the simulator main process and a preloaded small program interface. Under the condition that the applet to be simulated is updated, the simulator main process and the preloaded applet interface do not need to be reloaded, and the applet simulation efficiency is improved. Moreover, the small program interface part does not need to be reconstructed, namely, the research and development workload of a small program development tool does not need to be increased.
It should be noted that the applet development tool can be started in the following manner: the method comprises the steps that a main process of the simulator is pre-created in a rendering process, and initialization data of the main process of the simulator are sent, wherein the initialization data can be data used by a developer tool, such as the type of the simulator, the type of a panel for simulating operation and the like; starting a simulator working thread by a simulator main process; initializing a slave process; the simulator main process sends a creation completion message to the rendering process; the rendering process sends a simulator host process preparation complete message to the debugger process.
Moreover, because the slave process can be destroyed, the rendering process can pre-create the slave process, so that the subsequent use is facilitated; sending a slave process creation completion message to the rendering process after the slave process creation is completed; the rendering process sends a slave process ready completion (slave-ready message) to the debugger process, i.e. the applet development tool completes the launch. In the embodiment of the application, only one simulator main process is needed, the simulator main process cannot be destroyed, and the simulator working thread and the slave process can be destroyed.
According to the technical scheme of the embodiment of the application, in the small program page refreshing process, only the simulator working thread needs to be reloaded, other processes are not affected, and the small program page refreshing efficiency is improved. Moreover, the small program interface is placed in the main process of the simulator, and reconstruction is not needed, namely, the research and development workload of a small program development tool is not increased.
The present embodiment specifically describes a synchronous communication process of the simulator worker thread on the basis of the above embodiments. Fig. 4 a-4 d are timing diagrams of synchronous communications provided according to embodiments of the present application, respectively.
Referring to FIG. 4a, the simulator worker thread and simulator host process may communicate synchronously by: the simulator working thread can send a function call instruction to a simulator main process, wherein the function call instruction can comprise a function name, a function parameter and a unique function call identifier (also called as a unique synchronous communication identifier); the simulator main process executes the function to be called and writes an execution result into the shared memory; writing the unique function calling identifier into the shared memory as a wake-up identifier; before the simulator working thread enters the waiting state, the execution result is written into the shared memory when the condition that the awakening identifier exists in the shared memory is detected, and the simulator working thread can directly read the execution result from the shared memory without entering the waiting state.
Referring to FIG. 4b, the simulator worker thread and simulator host process may also communicate synchronously by: the simulator working thread can send a function calling instruction to the simulator main process; the simulator working thread detects whether the execution result in the shared memory is written in, and enters a waiting state under the condition of incomplete writing; the simulator main process executes the function to be called and writes an execution result into the shared memory; writing the unique function calling identifier into the shared memory as a wake-up identifier; the simulator main process also wakes up the simulator working thread after completing the writing; and the awakened simulator working thread reads an execution result from the shared memory.
Referring to FIG. 4c, the simulator worker thread and simulator host process may also communicate synchronously by: the simulator working thread can send a function calling instruction to the simulator main process; the simulator working thread detects whether the execution result in the shared memory is written in, and enters a waiting state under the condition of incomplete writing; the simulator main process executes the function to be called and writes an execution result into the shared memory; writing the unique function calling identifier into the shared memory as a wake-up identifier; and after the working thread of the simulator is in a waiting state for a certain time (such as after waiting for 5 ms), re-detecting whether the execution result in the shared memory is written into, and under the condition of finishing writing, finishing waiting. After the waiting is finished, the execution result can be read from the shared memory.
Referring to FIG. 4d, the simulator worker thread may also communicate synchronously with the simulator main process by: the simulator working thread can send a function calling instruction to the simulator main process; the simulator main process executes a function to be called; the simulator working thread detects whether the execution result in the shared memory is written in, and enters a waiting state under the condition of incomplete writing; after entering a waiting state for a certain time (such as after waiting for 5 ms), the working thread of the simulator detects whether the execution result in the shared memory is written into the shared memory again, and continues to wait under the condition that the writing is not finished; the simulator main process writes the execution result into the shared memory, and also writes the unique function calling identifier into the shared memory as a wake-up identifier; and after the writing is finished, the simulator main process wakes up the simulator working thread. The reason why the waiting time of the simulator worker thread is long may be that the execution time is too long after the simulator main process receives the asynchronous event. It should be noted that, if the synchronous communication time length exceeds the maximum communication time length threshold, for example, 3s, the synchronous communication is ended, and the timeout error notification is performed.
According to the technical scheme of the embodiment of the application, the state of the working thread of the simulator is controlled, so that the problem of deadlock abnormity of the working thread of the simulator and the main process of the simulator in the synchronous communication process can be avoided.
