Abstract

Methods and systems are described for providing transaction support for executable program components. In one embodiment, transaction information is associated with an instruction included in an executable addressable entity included in an executable program component generated from source code written in a programming language, wherein the transaction information is independent of the source code and the programming language. Further, an access to the instruction is detected for executing by a processor. A transaction operation to perform in association with the executing of the instruction is determined based on the transaction information associated with the instruction. The transaction operation is performed in association with the executing of the instruction, wherein the transaction operation is performed by a program component other than the executable program component including the executable addressable entity.

Claims

1. A method for providing transaction support for executable program components, the method comprising:

associating transaction information with an instruction included in an executable addressable entity included in an executable program component generated from source code written in a programming language, wherein the transaction information is independent of the source code and the programming language;

detecting an access to the instruction for executing by a processor;

determining a transaction operation to perform in association with the executing of the instruction based on the transaction information associated with the instruction; and

performing the transaction operation in association with the executing of the instruction, wherein the transaction operation is performed by a program component other than the executable program component including the executable addressable entity.

2. The method of claim 1 wherein associating transaction information with an instruction included in an executable addressable entity includes associating transaction information with a memory location associated with the instruction included in the executable addressable entity.

3. The method of claim 1 wherein the source code of the executable program component is in a processor independent programming language, wherein a plurality of machine code instructions, each executable by a specified processor from a different processor architecture family, can be generated from the source code.

4. The method of claim 1 wherein associating the transaction information with an instruction included in an executable addressable entity includes selecting the transaction information for association with the instruction according to an attribute of the executable addressable entity.

5. The method of claim 1 wherein the transaction information includes model information identifying a transactional model for determining a transaction operation to perform in association with the executing of the instruction.

6. The method of claim 1 including detecting an execution environment condition during the processing of the executable program component, and wherein associating the transaction information with the instruction included in the executable addressable entity is based on the detected execution environment condition.

7. The method of claim 1 wherein detecting an access to the instruction includes identifying access information associated with the access to the instruction, and

wherein determining a transaction operation to perform in association with the executing of the instruction is based on the access information and the transaction information.

8. The method of claim 1 wherein the transaction operation includes at least one of generating a new transaction, committing and terminating a transaction, aborting a transaction and rolling back changes made by the transaction, and invoking a specified event handler.

9. The method of claim 1 wherein the transaction operation is performed at least one of before the executing of the instruction, during the executing of the instruction and after the executing of the instruction.
