Abstract

A library controller that determines if a software is supported by an operating system is described. In one embodiment, the library controller receives the software and extracts library usage details from that software of a library that is provided by the operating system. In addition, the library controller compares the library usage details with library provisioning details of that library. Furthermore, the library controller presents results of the comparison.

Claims

1. A method comprising:

extracting, by a processing device, one or more first symbol and symbol version pairs and one or more argument types of each symbol and symbol version pair in the first symbol and symbol version pairs from software to be executed within an operating system without installing the software within the operating system, wherein the software uses a shared library within the operating system;

identifying one or more second symbol and symbol version pairs and one or more argument types of each symbol and symbol version pair in the second symbol and symbol version pairs provided by the shared library, wherein each symbol version in the one or more first symbol and symbol version pairs and the one or more second symbol and symbol version pairs comprises a sequential version identifier; and

comparing the one or more first symbol and symbol version pairs and the one or more argument types of each symbol and symbol version pair in the first symbol and symbol version pairs to corresponding ones of the one or more second symbol and symbol version pairs and the one or more argument types of each symbol and symbol version pair in the second symbol and symbol version pairs to determine that the software is not supported by the operating system.

2. The method of claim 1, wherein identifying the one or more second symbol and symbol version pairs and the one or more argument types of each symbol and symbol version pair in the second symbol and symbol version pairs comprises extracting the one or more second symbol and symbol version pairs and the one or more argument types of each symbol and symbol version pair in the second symbol and symbol version pairs from the shared library.

3. The method of claim 1, further comprising:

determining that there is a mismatch between the one or more first symbol and symbol version pairs and the one or more argument types of each symbol and symbol version pair in the first symbol and symbol version pairs and corresponding ones of the one or more second symbol and symbol version pairs and the one or more argument types of each symbol and symbol version pair in the second symbol and symbol version pairs; and

logging an error in response to determining that there is the mismatch.

4. The method of claim 1, further comprising:

saving the one or more first symbol and symbol version pairs in a database.

5. The method of claim 1, further comprising:

saving the one or more second symbol and symbol version pairs in a database.

6. A non-transitory computer readable storage medium having instructions stored thereon that, when executed by a processing device, cause the processing device to perform operations comprising:

extracting, by the processing device, one or more first symbol and symbol version pairs and one or more argument types of each symbol and symbol version pair in the first symbol and symbol version pairs from software to be executed within an operating system without installing the software within the operating system, wherein the software uses a shared library within the operating system;

identifying one or more second symbol and symbol version pairs and one or more argument types of each symbol and symbol version pair in the second symbol and symbol version pairs provided by the shared library, wherein each symbol version in the one or more first symbol and symbol version pairs and the one or more second symbol and symbol version pairs comprises a sequential version identifier; and

comparing the one or more first symbol and symbol version pairs and the one or more argument types of each symbol and symbol version pair in the first symbol and symbol version pairs to corresponding ones of the one or more second symbol and symbol version pairs and the one or more argument types of each symbol and symbol version pair in the second symbol and symbol version pairs to determine that the software is not supported by the operating system.

7. The non-transitory computer readable storage medium of claim 6, wherein identifying the one or more second symbol and symbol version pairs and the one or more argument types of each symbol and symbol version pair in the second symbol and symbol version pairs comprises extracting the one or more second symbol and symbol version pairs and the one or more argument types of each symbol and symbol version pair in the second symbol and symbol version pairs from the shared library.

8. The non-transitory computer readable storage medium of claim 6, wherein the operations further comprise:

determining that there is a mismatch between the one or more first symbol and symbol version pairs and the one or more argument types of each symbol and symbol version pair in the first symbol and symbol version pairs and corresponding ones of the one or more second symbol and symbol version pairs and the one or more argument types of each symbol and symbol version pair in the second symbol and symbol version pairs; and

logging an error in response to determining that there is the mismatch.

9. The non-transitory computer readable storage medium of claim 6, wherein the operations further comprise:

saving the one or more first symbol and symbol version pairs in a database.

10. The non-transitory computer readable storage medium of claim 6, wherein the operations further comprise:

saving the one or more second symbol and symbol version pairs in a database.

11. A system comprising:

a memory to store an operating system, a shared library, and software to be executed within the operating system without installing the software within the operating system; and

a processing device, coupled to the memory, to extract one or more first symbol and symbol version pairs and one or more argument types of each symbol and symbol version pair in the first symbol and symbol version pairs from the software, wherein the software uses a shared library within the operating system, identify one or more second symbol and symbol version pairs and one or more argument types of each symbol and symbol version pair in the second symbol and symbol version pairs provided by the shared library, wherein each symbol version in the one or more first symbol and symbol version pairs and the one or more second symbol and symbol version pairs comprises a sequential version identifier, and compare the one or more first symbol and symbol version pairs and the one or more argument types of each symbol and symbol version pair in the first symbol and symbol version pairs to corresponding ones of the one or more second symbol and symbol version pairs and the one or more argument types of each symbol and symbol version pair in the second symbol and symbol version pairs to determine that the software is not supported by the operating system.

12. The system of claim 11, wherein the processing device is further to identify the one or more second symbol and symbol version pairs and the one or more argument types of each symbol and symbol version pair in the second symbol and symbol version pairs by extracting the one or more second symbol and symbol version pairs and the one or more argument types of each symbol and symbol version pair in the second symbol and symbol version pairs from the shared library.

13. The system of claim 11, wherein the processing device is further to determine that there is a mismatch between the one or more first symbol and symbol version pairs and the one or more argument types of each symbol and symbol version pair in the first symbol and symbol version pairs and corresponding ones of the one or more second symbol and symbol version pairs and the one or more argument types of each symbol and symbol version pair in the second symbol and symbol version pairs, and log an error in response to the determination that there is the mismatch.

14. The system of claim 11, wherein the processing device is further to save the one or more first symbol and symbol version pairs in a database.

15. The system of claim 11, wherein the processing device is further to save the one or more second symbol and symbol version pairs in a database.
