Abstract

Runtime services for network software platforms are described. In one implementation, runtime services are configured for a web application. A configuration file is created containing tags that provide references to configuration information specific to operational behavior of the web application. The configuration file is read upon receiving a request to start the web application. The runtime services for the web application are initialized based on the configuration information read from the configuration file.

Claims

1. A method for expunging objects in memory that are not managed by a garbage collector (unmanaged objects) from memory, comprising:

receiving a request to process a web page containing an unmanaged object operating on a web server;

assigning a reference pointer to the unmanaged object;

storing the reference pointer in a data structure;

storing the unmanaged object in memory;

accessing the unmanaged object through a managed runtime service using a runtime callable wrapper via an interoperable bridge;

receiving a notification that the web page containing the unmanaged object is no longer being processed;

using the reference pointer to locate the unmanaged object in memory after receiving the notification; and

removing the unmanaged object from memory.

2. The method as recited in claim 1, wherein the unmanaged objects are component object model (COM) objects.

3. The method as recited in claim 1, further comprising assigning the reference pointer to the unmanaged object upon receiving the request.

4. The method as recited in claim 1, further comprising assigning a reference pointer to the unmanaged object when the unmanaged object is stored in memory.

5. The method as recited in claim 1, wherein the data structure is maintained in memory.

6. One or more computer-readable storage media comprising computer-executable instructions that, when executed, perform the method as recited in claim 1.

7. A computer-readable storage medium comprising computer-executable instructions that, when executed by a computer, direct the computer to perform operations comprising:

receive a request to process a web page containing an unmanaged object operating on a web server, the unmanaged object being an object that is not managed by a garbage collector that manages allocation and release of data from memory;

assign a reference pointer to the unmanaged object;

store the reference pointer in a data structure;

store the unmanaged object in memory;

access the unmanaged object through a managed runtime service using a runtime callable wrapper via an interoperable bridge;

receive a notification that the web page containing the unmanaged object is no longer being processed;

use the reference pointer to locate the unmanaged object in memory after receiving the notification; and

remove the unmanaged object from memory.

8. A computer-readable storage medium as recited in claim 7, wherein the unmanaged object is a component object model (COM) object.

9. A computer-readable storage medium as recited in claim 7, the operations further comprising tagging the unmanaged object when the unmanaged object is stored in memory.

10. A computer-readable storage medium as recited in claim 7, wherein the data structure is maintained in memory.

11. A computer comprising:

the computer-readable medium as recited in claim 7; and

a processor to execute the computer-executable instructions.

12. A system for automatically expunging unmanaged objects from memory, the unmanaged objects being objects for which memory is not automatically allocated and reclaimed by a garbage collector, the system comprising:

means for receiving a request to process a web page containing an unmanaged object operating on a web server;

means for assigning a reference pointer to the unmanaged object;

means for storing the reference pointer in a data structure;

means for storing the unmanaged object in memory;

means for accessing the unmanaged object through a managed runtime service using a runtime callable wrapper via an interoperable bridge;

means for receiving a notification that the web page containing the unmanaged object is no longer being processed;

means for using the reference pointer to locate the unmanaged object in memory after receiving the notification; and

means for removing the unmanaged object from memory.

13. The system as recited in claim 12, wherein the unmanaged objects are component object model (COM) objects.
