Abstract: Techniques are described for managing the optimized refreshing of metadata associated with online and live systems. In some implementations, a set of metadata modules associated with one or more entities are identified, the metadata modules defining metadata associated with a particular data model for the associated entities. A request to initiate a refreshing of the metadata for a subset of the set of metadata modules is identified. Each metadata module from the subset of the set of metadata modules is prioritized into a prioritization order. A determination is made as to whether two or more idle database connections are available. In response to determining that two or more idle database connections are available, a concurrent refresh of the subset of the set of metadata modules is initialized in the prioritization order.

Abstract: A first code version is received. The first code version includes a plurality of code features, such as methods or classes. A second code version is received. The second code version includes a plurality of code features. The first code version is executed. A first plurality of code features executed during the execution of the first code version are determined. A second plurality of code features differing between the first and second code versions are determined. The first and second plurality of code features are compared. An indication is provided that a code feature is potentially relevant to the code behavior if the code feature is present in the first plurality of code features and in the second plurality of code features.

Abstract: Disclosed herein is a framework for analyzing and determining the impact and importance of software code or method changes. In accordance with one aspect, invocations of methods are tracked by generating marking records. The marking records may be used to rebuild a call stack, which can be used to organize the methods to generate a calling dependency representation. The methods may then be ranked based on such calling dependency representation.

Abstract: An optical fiber is provided for optical sensing including a core extending along a length of the optical fiber, a cladding surrounding the core, the cladding including a plurality of channels extending along the length of the optical fiber; and a protrusion at a sensing end of the optical fiber, wherein the protrusion has a porous structure and a curved surface. There is also provided a method of manufacturing the optical fiber, a method of optically sensing an analyte, and an apparatus for optical sensing.
