Conditional locking mechanism for concurrent resource access in a multi-threaded environment

A method of generating a conditional lock in a multi-threaded environment, the method comprising:

• receiving, from a request source, a request to initiate an operation on a target resource on behalf of a first client thread, the request identifying request attributes including at least an operation type;
• identifying a predefined set of locking conditions collectively defining a granularity for conditionally locking the target resource, the predefined set of locking conditions corresponding to the request attributes and identifying the operation type;
• generating a unique key based on the request attributes of the request that correspond to the predefined set of locking conditions;
• searching a concurrency dictionary for an existing lock identifier associated with the unique key;
• in response to determining that the unique key is not associated with an existing lock identifier, acquiring a lock object from an operating system and associating an identifier of the lock object with the unique key in the concurrency dictionary, wherein acquisition of the lock object prevents concurrent execution of operations of the operation type on the target resource without preventing concurrent execution of all possible types of operations on the target resource;
• transmitting a lock acquisition confirmation to the request source;
• and
• requesting, from the operating system, release of the lock object from the first client thread in response to receiving a confirmation that the operation has completed, wherein the operation is conditionally executed on the target resource in response to receipt of the lock acquisition confirmation.

A system for conditionally locking a shared resource, the system comprising:

• a concurrency manager stored in memory that:
• receives, from a multi-threaded application, a request identifying an operation on a target resource requested by a first client thread, the request identifying request attributes including an operation type;
• identifies a predefined set of locking conditions collectively defining a granularity for conditionally locking the target resource, the predefined set of locking conditions corresponding to the request attributes and identifying the operation type;
• generates a unique key based on the request attributes that correspond to the predefined set of locking conditions;
• searches a concurrency dictionary for an entry identifying the unique key;
• in response to determining that the concurrency dictionary includes an entry identifying the unique key, identifies a lock object that is associated with the unique key in the entry, the lock object being a synchronization primitive provided by an operating system that, when acquired by an application in association with the unique key, prevents concurrent execution of operations of the operation type on the target resource without preventing concurrent execution of all possible types of operations on the target resource;
• transmits a request on behalf of the first client thread for acquisition of the lock object associated with the unique key in the entry,
• in response to confirming that the first client thread has acquired the lock object, transmitting a lock acquisition confirmation to the multi-threaded application, wherein the multi-threaded application conditionally executes the operation on the target resource in response to receipt of the lock acquisition confirmation.
