Abstract: A process in a system can monitor available free storage space on a storage device, and, based on preset log file parameters, can act upon log files being stored on or written to the storage device to keep the storage device from running out of storage space due to excessive logging. The process monitors the device free space as reported by the file system to determine space utilization. A threshold of free space can be specified as a parameter. A log file action can also be specified as a parameter and is an action designed to reduce the space being used by a log file or log files. Once the process recognizes that the free space is under the threshold it will perform the configured action.

A new cell in the new column includes a timer indicating a time that the processing device will call the function, and the new cell references the function. The method may also include, upon expiration of the timer, determining that the database management system is available for execution of the function, and executing the function on the particular row in the table.

Abstract: Log record analysis based on log record templates is disclosed. A plurality of log records that comprise log data generated by one or more logging entities over a period of time is accessed. Each log record of the plurality of log records corresponds to one log record template of a plurality of different log record templates. The log records are analyzed to determine a particular log record template of the plurality of different log record templates to which a majority of the plurality of log records corresponds. An action is taken that is at least partially based on the particular log record template.

Abstract: A system includes a memory and a processor in communication with the memory. The processor builds a preliminary history list of a plurality of commits including intermediary commits and a target commit, instantiates a target file list of files modified by the target commit, and instantiates an intermediary file list for each intermediary commit. Additionally, the processor classifies each intermediary commit as an intersecting commit or an empty commit. Responsive to classifying a respective intermediary commit as an empty commit, the processor removes the respective intermediary commit from the preliminary history list to create a candidate history list. Responsive to classifying a respective intermediary commit as an intersecting commit, the processor retains the respective intermediary commit in the candidate history list. Additionally, the processor joins the respective intermediary file list with the target file list and creates a finalized history list.

Abstract: Methods and systems for communicating between nodes within computing clusters. In one embodiment, a method is provided that includes receiving, at a first node within a first cluster, a packet for transmission from a second node within the first cluster.

The routing agent may also generate a second destination address corresponding to a third node of the second cluster and transmit the packet to the second destination address via an external tunnel between a plurality of clusters including the first cluster and the second cluster.

Abstract: Some examples of the present disclosure relate to troubleshooting test failures that occurred during a testing phase of a continuous integration pipeline. In one particular example, a system can detect that an artifact failed the testing phase. The testing phase can involve each worker node in a plurality of worker nodes executing a respective group of tests on the artifact. Based on detecting that the artifact failed the testing phase, the system can determine a particular worker node that executed a test that failed during the testing phase. The system can then determine the respective group of tests that was executed by the particular worker node during the testing phase. The system can re-execute the respective group of tests on the artifact in accordance with troubleshooting rules to determine a reason that the test failed during the testing phase.

Abstract: Methods and systems for improved test execution and log file tracking are presented. In one embodiment, a method includes receiving a log file, which may be associated with a test. An original logging position of the log file may be stored and the test may be executed. Executing the test may cause logging information to be appended to the original logging position at the original logging position. An output file corresponding to the log file may be created and the original logging position within the log file may be located. A portion of the log file may then be copied to the output file starting at the original logging position.

Abstract: Implementations of the disclosure provide for hot-plugging of virtual functions in a virtualized environment. In one implementation, a computer system determines that virtual functions associated with a logical network for a virtual machine hosted on a first host system are unavailable on the first host system, identifies a logical network device on a second host system that is communicably accessible from the first host system, and determines that the logical network device on the second host system has a number of available virtual functions associated with the logical network. The computer system then migrates the virtual machine from the first host computer system to the second host computer system to allow the virtual machine to access the number of available virtual functions associated with the logical network on the second host system and associates a virtual device of the virtual machine with the number of available virtual functions.
