Patent number: 9880943Abstract: Disclosed here are methods, systems, paradigms and structures for deleting shared resources from a cache in a multi-threaded system. The shared resources can be used by a plurality of requests belonging to multiple threads executing in the system. When requests, such as requests for executing script code, and work items, such as work items for deleting a shared resource, are created, a global sequence number is assigned to each of them. The sequence number indicates the order in which the requests and work items are created. A particular work item can be executed to delete the shared resource if there are no requests having a sequence number lesser than that of the particular work item executing in the system. However, if there is at least one request with a sequence number lesser than that of the particular work item executing, the work item is ignored until the request completes executing.Type: GrantFiled: June 10, 2016Date of Patent: January 30, 2018Assignee: Facebook, Inc.Inventors: Keith Adams, Jason Owen Evans

Patent number: 9697022Abstract: Scripts are incrementally compiled at runtime to generate executable code. The incremental compilation generates executable code corresponding to a basic block of the script. The executable code for a basic block of script is generated for a set of types of variables of the basic block resulting from execution of the script in response to a request. The generated executable code is stored and executed for subsequent requests if these requests result in the same types of variables for the basic block. The incremental compilation of the script is performed in a lazy fashion, such that executable code is not generated for combinations of types of variables of the script code that are not obtained from requests received at runtime. The script may dynamically generate portions of a web page that is returned in response to a request for execution of the script.Type: GrantFiled: May 28, 2015Date of Patent: July 4, 2017Assignee: Facebook, Inc.Inventors: Keith Adams, Andrew John Paroski, Jason Owen Evans

When requests, such as requests for executing script code, and work items, such as work items for deleting a shared resource, are created, a global sequence number is assigned to each of them. The sequence number indicates the order in which the requests and work items are created. A particular work item can be executed to delete the shared resource if there are no requests having a sequence number lesser than that of the particular work item executing in the system. However, if there is at least one request with a sequence number lesser than that of the particular work item executing, the work item is ignored until the request completes executing.Type: ApplicationFiled: June 10, 2016Publication date: September 29, 2016Inventors: Keith Adams, Jason Owen Evans
