Method and device for inter-process communication

Abstract

The present application discloses a method for inter-process communication. In one example, if a first process needs to send a message to a second process, the first process can determine a target IPC channel from a plurality of IPC channels, and send the message to be sent to the second process through the target IPC channel. The first process is the process of the installation-free application, and the second process is the core process of the installation-free framework; or, the first process and the second process are both processes of the installation-free application. Since the possibility of the multiple IPC channels failing at the same time is extremely small, even if one of the IPC channels fails, the first process can determine a target IPC channel that is not failing from the multiple IPC channels, thereby implementing IPC to ensure normal business operation. It can be seen that by utilizing this solution, IPC failures between the second process and the first process in the installation-free application can be avoided, thereby ensuring normal business operation.

[0050] In order to help those skilled in the art better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0051] Various non-limiting embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0052] Exemplary Methods

[0053] See also Figure 1 , which is a flow chart of a method for inter-process communication provided by an embodiment of the present application. In one example, the method can be used to implement inter-process communication in an installation-free framework.

[0054] Regarding the free installation framework, it should be noted that:

[0055] Installation-free technology provides a complete virtual operating environment. Applications that utilize this technology are also known as "installation-free apps." These apps can achieve the same performance as installed apps without needing to be installed on the operating system. The operating system can run platform applications, which in turn can run the installation-free framework, which is used to implement the installation-free technology.

[0056] Figure 1 The method shown may include, for example, the following steps S101 - S102 .

[0057] S101: A first process determines a target IPC channel from multiple IPC channels.

[0058] S102: The first process sends the message to be sent to the second process through the target IPC channel, wherein: the first process is the process of the installation-free application, and the second process is the core process of the installation-free framework; or, the first process and the second process are both processes of the installation-free application.

[0059] In an embodiment of the present application, multiple IPC channels may be provided for implementing IPC. If a first process needs to send a message to a second process, a target IPC channel may be first determined from the multiple IPC channels, and the message to be sent may be sent to the second process via the target IPC channel.

[0060] The target IPC channel is an available IPC channel among the multiple IPC channels. The available IPC channel mentioned here may refer to an IPC channel that has not experienced any failure.

[0061] The first process may be a process of an installation-free application, such as a process of an installation-free game. The second process may be a core process of an installation-free framework. In another example, the first process and the second process are both processes of the installation-free application, the first process being one of the processes of the installation-free application, and the second process being the main process of the installation-free application. The main process refers to the first process that runs when the installation-free application is started.

[0062] In one implementation of the embodiment of the present application, the first process may determine the target IPC channel from the multiple IPC channels according to the configuration information.

[0063] In one example: the configuration information may indicate one of the multiple IPC channels as the default channel, and indicate that the other IPC channels are used as backup channels. In some embodiments, the multiple IPC channels include a first IPC channel and a second IPC channel, and the configuration information indicates that the first IPC channel is the default channel and the second IPC channel is the backup channel. Then, the first process may determine the first IPC channel as the target IPC channel if the first IPC channel is not faulty, and the first process may determine the second IPC channel as the target IPC channel if the first IPC channel is faulty. The first process may determine that the default channel is faulty if it sends a message to the second process through the default channel but does not receive a response returned by the second process.

[0064] In another example: the configuration information includes the priorities corresponding to the multiple IPC channels, and the first process preferentially determines the IPC channel with a high priority as the target IPC channel. When the IPC with a high priority fails, the target IPC channel is determined from the other IPC channels in descending order of priority. For example, the multiple IPC channels include a first IPC channel, a second IPC channel, and a third IPC channel, and the configuration information indicates that the priority of the first IPC channel is higher than the priority of the second IPC channel, and the priority of the second IPC channel is higher than the priority of the third IPC channel. Then the first process can determine the first IPC channel as the target IPC channel if the first IPC channel does not fail; if the first IPC channel fails and the second IPC channel does not fail, the first process determines the second IPC channel as the target IPC channel; if both the first IPC channel and the second IPC channel fail, the first process determines the third IPC channel as the target IPC channel.

[0065] Regarding the multiple IPC channels, the present application embodiment does not make specific limitations. In one example, if the operating system carrying the free installation framework is an Android system, the multiple IPC channels can be content provider channels and service channels. Figure 2 To understand, Figure 2 A schematic diagram provided for an embodiment of the present application. Figure 2 In the example, a ContentProvider channel and a Service channel are located between the first process 201 and the second process 202. In this case, the ContentProvider channel and the Service channel serve as backups for each other. If one of the two channels fails, the other channel is switched to. Both ContentProvider and Service are components of the Android system and are not described in detail here.

[0066] In one example, considering that the Service is mainly used to process background-related operations, the ContentProvider channel can be determined as the default IPC channel, and the Service channel can be used as a backup channel, or the priority of the ContentProvider channel can be set higher than the priority of the Service channel. That is, the ContentProvider channel is used first to implement IPC, and in the event that the ContentProvider channel fails, the Service channel is used to implement IPC. In this case, if the current channel (i.e., the ContentProvider channel) does not fail, the target IPC channel is the ContentProvider channel; if the current channel (i.e., the ContentProvider channel) fails, it switches to another channel (i.e., the Service channel). In this case, the target IPC channel is the Service channel.

[0067] In another example, since the time consumption of the Service channel is less than that of the ContentProvider channel, the Service channel can be determined as the default IPC channel, and the ContentProvider channel can be used as a backup channel, or the priority of the Service channel can be set higher than the priority of the ContentProvider channel. That is, the Service channel is used first to implement IPC, and in the event of a failure in the Service channel, the ContentProvider channel is used to implement IPC. In this case, if the current channel (i.e., the Service channel) has not failed, the target IPC channel is the Service channel; if the current channel (i.e., the Service channel) fails, it switches to another channel (i.e., the ContentProvider channel). In this case, the target IPC channel is the ContentProvider channel. This solution can reduce the time consumption of inter-process communication and improve communication efficiency.

[0068] In an embodiment of the present application, if the first process and the second process communicate using a Service channel, the communication between the two is asynchronous. In this case, the first process can bind the Service channel before using the Service channel to send data to the second process, thereby realizing synchronous communication. Wherein: when the first process binds the Service channel, for example, it can send a request to bind the Service channel to the Service component. After sending the request, the first process performs a locking operation to wait for a confirmation message from the Service component. After the first process receives the confirmation message returned by the Service component for the request, it is considered that the first process has successfully bound the Service channel. At this time, the first process can use the Service channel to communicate synchronously with the second process. It should be noted that the so-called execution of the locking operation means that the first process no longer interacts with other processes for data.

[0069] As can be seen from the above description, since the possibility of multiple IPC channels failing simultaneously is extremely small, even if one of the IPC channels fails, the first process can still determine the target IPC channel that is not failing from the multiple IPC channels, thereby implementing IPC to ensure normal business operation. It can be seen that the solution provided by the embodiment of the present application can avoid IPC failures between the second process and the first process in the installation-free application, thereby ensuring normal business operation.
