Abstract

A computing device receives an object at runtime of a compiled application, wherein the object is a component of the application. The computing device generates a transactional proxy for the object, the transactional proxy including transactional logic, a transactional marker and a pointer to the object. The transactional proxy is passed to the application, wherein the application to make calls on the transactional proxy instead of on the object.

Claims

1. A method, comprising:

receiving, by a processing device, a non-transactional object at runtime of a compiled application, wherein the non-transactional object is a component of the application that does not include transactional logic;

generating, by the processing device, a transactional proxy for the non-transactional object, the transactional proxy including the transactional logic not included in the non-transactional object, a transactional marker and a pointer to the non-transactional object;

determining, by the processing device, a locking strategy to use for the non-transactional object, the locking strategy to be implemented by the transactional proxy; and

passing, by the processing device, the transactional proxy to the application, wherein the application to make calls on the transactional proxy instead of on the non-transactional object.

2. The method of claim 1, wherein the transactional logic comprises logic for generating locks, for creating transaction logs, and for committing and aborting transactions, and wherein the transactional marker identifies to a transaction system that the transactional proxy is to be managed transactionally.

3. The method of claim 1, further comprising:

receiving a command by the transactional proxy to perform an action;

determining the locking strategy to use for the non-transactional object based on the received command;

setting a lock for the non-transactional object after determining the locking strategy; and

forwarding the command to the non-transactional object.

4. The method of claim 3, wherein the command is a command to modify a state of the non-transactional object, the method further comprising:

determining that a write lock is appropriate;

saving the state of the non-transactional object;

setting the write lock for the non-transactional object; and

enrolling in an active transaction for the non-transactional object.

5. The method of claim 3, wherein the command is a command to read a state of the non-transactional object, the method further comprising:

determining that a read lock is appropriate; and

setting the read lock for the non-transactional object.

6. The method of claim 1, further comprising:

receiving a command to generate the non-transactional object;

generating the non-transactional object using a first factory object; and

generating the transactional proxy for the non-transactional object using a second factory object that wraps the first factory object.

7. The method of claim 1, further comprising:

receiving a command by the transactional proxy to perform an action;

setting a lock for the non-transactional object based on a locking strategy that has been specified by an application optimizer, wherein the application optimizer monitored the behavior of the non-transactional object to identify the locking strategy; and

forwarding the command to the non-transactional object.

8. A computing apparatus, comprising:

a memory; and

a processing device, connected with the memory, the processing device being configured to;

receive a non-transactional object at runtime of a compiled application, wherein the non-transactional object is a component of the application that does not include transactional logic;

generate a transactional proxy for the non-transactional object, the transactional proxy including the transactional logic not included in the non-transactional object, a transactional marker and a pointer to the non-transactional object;

determine, by the processing device, a locking strategy to use for the non-transactional object, the locking strategy to be implemented by the transactional proxy; and

pass the transactional proxy to the application, wherein the application to make calls on the transactional proxy instead of on the non-transactional object.

9. The computing apparatus of claim 8, wherein the transactional logic comprises logic for generating locks, for creating transaction logs, and for committing and aborting transactions, and wherein the transactional marker identifies to a transaction system that the transactional proxy is to be managed transactionally.

10. The computing apparatus of claim 8, the processing device being further configured to:

receive a command by the transactional proxy to perform an action;

determine the locking strategy to use for the non-transactional object based on the received command;

set a lock for the non-transactional object after determining the locking strategy; and

forward the command to the non-transactional object.

11. The computing apparatus of claim 10, wherein the command is a command to modify a state of the non-transactional object, the processing device being further configured to:

determine that a write lock is appropriate;

save the state of the non-transactional object;

set the write lock for the non-transactional object; and

enroll in an active transaction for the non-transactional object.

12. The computing apparatus of claim 10, wherein the command is a command to read a state of the non-transactional object, the processing device being further configured to:

determine that a read lock is appropriate; and

set the read lock for the non-transactional object.

13. The computing apparatus of claim 8, the processing device being further configured to:

receive a command to generate the non-transactional object;

generate the non-transactional object using a first factory object; and

generate the transactional proxy for the non-transactional object using a second factory object that wraps the first factory object.

14. The computing apparatus of claim 8, the processing device being further configured to:

receive a command by the transactional proxy to perform an action;

set a lock for the non-transactional object based on a locking strategy that has been specified by an application optimizer, wherein the application optimizer monitored the behavior of the non-transactional object to identify the locking strategy; and

forward the command to the non-transactional object.

15. A non-transitory computer readable storage medium including instructions that, when executed by a processing device, cause the processing device to perform a method comprising:

receiving, by the processing device, a non-transactional object at runtime of a compiled application, wherein the non-transactional object is a component of the application that does not include transactional logic;

generating, by the processing device, a transactional proxy for the non-transactional object, the transactional proxy including the transactional logic not included in the non-transactional object, a transactional marker and a pointer to the non-transactional object;

determining, by the processing device, a locking strategy to use for the non-transactional object, the locking strategy to be implemented by the transactional proxy; and
