Abstract

In general, one innovative aspect of the subject matter described in this specification can be embodied in methods that include the actions of receiving an input method editor (IME) server request, the IME server request including one or more tokens and requesting that an IME server be instantiated, the IME server executing one or more IME functions based on a key event sent from an IME client, wherein the IME server is a stateful server that stores both requests and responses of a communication session between the IME server and the IME client, determining that the IME server can be instantiated in a restrictive environment based on the one or more tokens, and instantiating the IME server in the restrictive environment. Other embodiments of this aspect include corresponding systems, apparatus, and computer programs, configured to perform the actions of the methods, encoded on computer storage devices.

Claims

1. A computer-implemented method, comprising:

receiving an input method editor (IME) server request, the IME server request including one or more tokens and requesting that an IME server be instantiated, the IME server executing one or more IME functions based on a key event sent from an IME client, wherein the IME server is a stateful server that stores both requests and responses of a communication session between the IME server and the IME client;

determining that the IME server can be instantiated in a restrictive environment based on the one or more tokens; and

instantiating the IME server in the restrictive environment.

2. The computer-implemented method of claim 1, further comprising:

executing one or more checks that verify that that IME server is instantiated in the restrictive environment;

determining that the IME server is not executing in the restrictive environment based the one or more checks; and

halting the IME server in response to determining that the IME server is not executing in the restrictive environment.

3. The computer-implemented method of claim 2, wherein the one or more checks include at least one of comparing a token value to an expected value, comparing a session identification of the IME server to an expected identification, determining that the IME server has system privileges, and determining the result of a revert function

4. The computer-implemented method of claim 1, further comprising:

executing one or more checks that verify that that IME server is instantiated in the restrictive environment; and

determining that the IME server is executing in the restrictive environment based on the one or more checks.

5. The computer-implemented method of claim 1, wherein the restrictive environment limits types of data that the IME server can write to memory.

6. The computer-implemented method of claim 1, wherein the IME server request is generated by the IME client, and the IME client is a stateless IME client that stores only requests it issues to the IME server.

7. The computer-implemented method of claim 1, further comprising:

instantiating the restrictive environment based on a first token to provide a first restriction level of the restrictive environment;

executing the IME server within the restrictive environment at the first restriction level;

calling a function;

re-instantiating the restrictive environment based on a second token to provide a second restriction level in response to the function.

8. The computer-implemented method of claim 7, wherein the first restriction level is different from the second restriction level.

9. The computer-implemented method of claim 1, wherein the IME client and the IME server are executed on a common device.

10. A system, comprising:

a computer-readable storage medium having instructions stored thereon; and

a device including one or more data processing apparatus that execute the instructions to cause the one or more data processing apparatus to perform operations comprising;

receiving an input method editor (IME) server request, the IME server request including one or more tokens and requesting that an IME server be instantiated, the IME server executing one or more IME functions based on a key event sent from an IME client, wherein the IME server is a stateful server that stores both requests and responses of a communication session between the IME server and the IME client;

determining that the IME server can be instantiated in a restrictive environment based on the one or more tokens; and

instantiating the IME server in the restrictive environment.

11. The system of claim 10, wherein the operations further comprise:

executing one or more checks;

determining that the IME server is not executing in the restrictive environment based on the one or more checks; and

halting the IME server in response to determining that the IME server is not executing in the restrictive environment.

12. The system of claim 11, wherein the one or more checks include at least one of comparing a token value to an expected value, comparing a session identification of the IME server to an expected identification, determining that the IME server has system privileges, and determining the result of a revert function

13. The system of claim 10, wherein the operations further comprise:

executing one or more checks that verify that that IME server is instantiated in the restrictive environment; and

determining that the IME server is executing in the restrictive environment based on the one or more checks.

14. The system of claim 10, wherein the restrictive environment limits types of data that the IME server can write to memory.

15. The system of claim 10, wherein the IME server request is generated by the IME client, and the IME client is a stateless IME client that stores only requests it issues to the IME server.

16. The system of claim 10, wherein the operations further comprise:

instantiating the restrictive environment based on a first token to provide a first restriction level of the restrictive environment;

executing the IME server within the restrictive environment at the first restriction level;

calling a function;

re-instantiating the restrictive environment based on a second token to provide a second restriction level in response to the function.

17. The system of claim 16, wherein the first restriction level is different than the second restriction level.

18. A computer-implemented method, comprising:

receiving an input method editor (IME) server request, the IME server request including one or more tokens and requesting that an IME server be instantiated, the IME server executing one or more IME functions based on a key event sent from an IME client, wherein the IME server is a stateful server that stores both requests and responses of a communication session between the IME server and the IME client;

processing the one or more tokens;

determining that the IME server can be instantiated based on the processing;

instantiating the IME server in a restrictive environment, the restrictive environment limiting the functionality of the IME server;

determining that the IME server is not executing in the restrictive environment; and

halting the IME server in response to the determining.

19. A system, comprising:

a computer-readable storage medium having instructions stored thereon; and

a device including one or more data processing apparatus that execute the instructions to cause the one or more data processing apparatus to perform operations comprising;

receiving an input method editor (IME) server request, the IME server request including one or more tokens and requesting that an IME server be instantiated, the IME server executing one or more IME functions based on a key event sent from an IME client, wherein the IME server is a stateful server that stores both requests and responses of a communication session between the IME server and the IME client;
