Abstract: Methods and systems are disclosed for flexibly managing lock modes in a data-sharing environment, including optimistic and pessimistic lock modes. A lock mode determination service receives a request from an application instance for a lock mode with which to access specified data objects. The service can determine and provide a suitable lock mode based on a context of the application, and optionally other parameters, by evaluating a checklist of criteria sorted in precedential order. Criteria can include geo-boundaries, platform, role, and others. The requesting application instance uses the determined lock mode to access the data, with optional assistance of a lock service. The lock mode determination service can support one or more applications having one or more instances each, and can also support multiple disjoint data-sharing environments. Suitable environments include cloud, datacenter, mobile, client-server, and SAAS.

Abstract: Snapshot data (e.g., changed blocks) resulting from operation of applications is captured in two forms: (1) in a bitmap that indicates if one or more blocks in a range of blocks has changed, and (2) as the changed block data itself. The changed blocks are sent to a remote disaster recovery location only once per snapshot period. Even through a particular block might have been changed many times during a snapshot period, only the last version of the changed block is sent to the remote disaster recovery location. The fact that a block has been changed can be parsimoniously managed by determining an address space for the source data, dividing the address space into a plurality of ranges, and indicating which blocks if any in a particular range have been changed. Such modification indicators are sent to the disaster recovery location only once per snapshot period.

Abstract: The objects of an on object set may be synchronized across many clients (e.g., various devices may synchronize files of a mirrored filesystem). However, the synchronization of an object may be complicated, and an object may not yet be synchronized in the object set of a client for many reasons, such as an incomplete reception of the object, an unavailability of the object from currently reachable hosts, and a versioning conflict with a different version of the same object in the object set. In order to inform a user of the availability of an object in the object set, an analysis of the availability status of the object may be performed (e.g., by tracking metadata stored in object descriptors of respective objects of the object set, and later examining the metadata of respective objects), and a selected availability status may be presented to the user.

Abstract: A system for parallel processing tasks by allocating the use of exclusive locks to process critical sections of a task. The system includes storing update information that is updated in response to acquisition and release of an exclusive lock. When processing a task which includes a critical section containing code affecting execution of the other task, an exclusive execution unit acquires an exclusive lock prior to processing the critical section. When the section has been processed successfully, the lock is released and update information updated. Meanwhile a second task, whose critical section does not contain code affecting execution of the other task may run in parallel, without acquiring an exclusive lock, via a nonexclusive execution unit. The nonexclusive execution unit determines that the second critical section has successfully completed if the update information has not changed during processing of the second critical section.
