Abstract: Disclosed herein are embodiments for performing multi-version concurrency control (MVCC) in non-volatile memory. An embodiment operates by determining that an event occurred, wherein one or more write transactions to one or more records of a multi-version database that were pending prior to the event did not commit. The one or more write transactions are identified based on a commit value that was stored in the non-volatile memory prior to the event. A particular one of the identified uncommitted write transactions is selected. From the multi-version database, a first version of a record corresponding to the selected uncommitted write transaction that was not committed, and an earlier version of the record that was committed prior to the event are identified. A visibility of the record is set to indicate that the earlier version of the record is visible and the first version of the record is not visible.

Abstract: A method, a system, and a computer program product for performing testing of continuous log replays in a database system. A redo log generated for a data record in a database is received. The redo log is indicative of a change in persistency of the data record in the database. Based on the change in persistency recorded in the redo log, a redo handler in the plurality of handlers is selected for execution of a replay of the received redo log. Using the selected redo log, replay of the redo log is executed to generate a state of the data record prior to the change in persistency recoded in the redo log.

Abstract: A system for sensor-based tracking of participants of a sporting activity is provided.

The operations further comprise determining, in response to detecting an action which at least changes the location of the tracked object, a second probability of the team (or an opposing team (successfully scoring, and assigning, based on a difference between the first probability and the second probability, at least a portion of the difference among one or more of the plurality of participants. Related systems, methods, and articles of manufacture are also described.

Abstract: Embodiments protect against security vulnerabilities arising from 3rd party JavaScript code. A browser receives from a server, a document including a first JavaScript. The browser in turn references a list stored in a database to recognize the first JavaScript as originating from other than the server. This recognition process may involve obtaining a stacktrace. The browser then references a second JavaScript in order to instrument a document object model (DOM) feature (e.g., global API, DOM element-attached API, DOM node property) to sanitize the first JavaScript. For instrumenting a global API, this may comprise overwriting a global reference in the first JavaScript with a replacement reference to a sanitization function. For instrumenting the DOM element-attached API or the DOM node property, the instrumenting may comprise altering a prototype of the DOM node element. The browser causes the DOM feature to sanitize the first JavaScript, and passes a sanitized JavaScript for execution.

Abstract: Capability information for a sensor agent is received. The capability information includes one or more metrics that the sensor agent is configured to provide. The sensor agent is configured in accordance with an initial configuration including a first level of granularity for test data. When the test data is received from the sensor agent, a value of at least one metric from the one or more metrics is tested in a machine learning module. The value is classified based on an output from the machine learning module. The initial configuration of the sensor agent is automatically adjusted to adaptively define a second level of granularity for the test data provided by the sensor agent.

Abstract: Methods and system are disclosed that replicate data between source databases and destination databases. In one aspect, the source databases and the destination databases may be deployed in multiple cloud computing environments. The mechanism for replicating data from a source database to a destination database may include receiving a request to replicate data. Based on multiple identifiers associated with data, a coordinator component may determine the data to be replicated. Based on the determination, the coordinator component may generate multiple replicator requests. The replicator requests may be sent to a replicator component by a processor component. The replicator component may execute the replicator requests to replicate the data from the source database to the destination database.

Abstract: A method for logging changes to data stored in a distributed data storage system can include responding to a request to change the data stored in the distributed data storage system by generating a log entry corresponding to the change.

Abstract: The disclosure generally describes methods, software, and systems, including a method for managing modifications to a document by collaborators. A digital document is identified for collaboration by a first user having ownership privileges for the document. The collaboration is associated with at least one collaborator. A duplicate version of the identified document is provided to each of the identified collaborators. The duplicate versions are monitored for modifications performed by corresponding collaborators. A list of modifications is created that identifies the modifications performed by the corresponding collaborators in the duplicate versions associated with those collaborators. A selection from the list of modifications is received from the first user of at least one modification for incorporation into the identified document. Based on the received selection, the selected at least one modification is merged into the identified document.

Abstract: Embodiments map from a database environment, dependencies between files created at designtime and corresponding runtime data objects defined by deployment of those files. A dependency table is populated with dependency information (e.g., origin, target, dependency type) extracted during deployment. That dependency information may be searched according to user-specified parameters (e.g., a file provides an object; an object requires a file), to allow rapid correlation between designtime file(s) and related runtime data object(s). Embodiments are particularly useful in visualizing complex (e.g., one-to-many; many-to-one) file-object dependencies characteristic of modern database environments. Queries posed to the dependency table may further seek intra-designtime dependency information (e.g., one file depends upon another file; one file impacts another file), and/or intra-runtime dependency information (e.g., table objects referenced by view objects; view objects referenced by procedure objects).
