Abstract: Mechanisms are provided for collecting telemetry data from an observability tool of a container executing on a host computing system. The mechanisms configure a shared memory to implement a telemetry data buffer. The telemetry data buffer is shared by observability tool instances of a plurality of containers on one or more host computing systems. Observability tool instance(s) collect telemetry data from a corresponding container in the plurality of containers. The collected telemetry data is written to a record in the telemetry data buffer. A backend computing system accesses the records in the telemetry data buffer to apply analytics to the telemetry data.

Abstract: A computer-implemented method includes creating a first file control block in a primary runtime environment with a first addressing mode and a second file control block in a secondary runtime environment with a second addressing mode, where both the first file control block and the second file control block describe a status of a first file of a caller program in the primary runtime environment. The parameters of the first file of the caller program in the primary runtime environment are passed to a target callee program in the secondary runtime environment. An anchor is added in the first file control block as a link to the second file control block. The first file control block are the second file control block synchronized with updates to the first file in the primary runtime environment and the passed parameters of the first file in the secondary runtime environment.

Abstract: A thread management process where a storage area template is generated for a plurality of threads that are to be created by a process in a computing system, the storage area template comprising at least one module template for at least one library that is to be loaded by the process. In the computing system, a plurality of storage areas is allocated for the plurality of threads based on the storage area template, respectively. The plurality of threads are managed based on the plurality of storage areas, respectively. All threads and libraries may be managed in a uniform way according to the storage area template. Therefore, thread management may be simplified and then may lead to reduced costs in the storage and time resources.

Abstract: A first memory page in a memory of the computer is allocated as a first stack to buffer meta data for function calls in the program. A memory protection key for the first memory page is generated. A second memory page in the memory is allocated as a second stack to buffer user data for function calls in the program.

Abstract: Global variables are shared between programs associated with different addressing modes. A first program of an application records an allocated address to a global variable in a global variable sharing area (GVSA). The first program is associated with a first addressing mode. The first program specifies the global variable to be shared across different addressing modes. An address of the GVSA is passed to a second program of the application that is loaded after the first program has been loaded. The second program is associated with a second addressing mode different from the first addressing mode. The second program also specifies the global variable in the second program to be shared across different addressing modes. The second program retrieves the allocated address to the global variable from the GVSA based on the address of the GVSA. The second program accesses the global variable based on the retrieved allocated address.

Abstract: A call to an external interface to execute a target callee program associated with a first addressing mode in a secondary runtime environment (RTE) is received from a caller program associated with a second addressing mode running in a primary RTE. An address of a share area (SA) storing existing dynamic link object information in the primary RTE in storage is passed to the secondary RTE. The SA is accessible by both the caller program and the target callee program. In response to a request to load a dynamic link object by an initiating program during execution of the target callee program in the secondary RTE, an entry address of the dynamic link object is retrieved in the SA. The dynamic link object is loaded based on the retrieved entry address of the dynamic link object.

Abstract: Aspects of the invention include creating a first file control block in a primary runtime environment with a first addressing mode and a second file control block in a second runtime environment with a second addressing mode, where both the first file control block and the second file control block describe a status of a first file of a caller program in the primary runtime environment. The parameters of the first file of the caller program in the primary runtime environment are passed to a target callee program in the secondary runtime environment. An anchor is added in the first file control block as a link to the second file control block. The first file control block are the second file control block synchronized with updates to the first file in the primary runtime environment and the passed parameters of the first file in the secondary runtime environment.

Abstract: Embodiments of the present disclosure relate to a method, system, and computer program product for exception handling. In some embodiments, a method is disclosed. According to the method, in response to an application throwing an exception, a target stack frame for handling the exception is detected from a call stack of the application. The call stack comprises a plurality of stack frames. One of the plurality of stack frames corresponds to a function called by the application and supports either a one-phase exception handling mechanism or a two-phase exception handling mechanism. In response to the target stack frame being detected from the call stack, the target stack frame is caused to handle the exception. In other embodiments, a system and a computer program product are disclosed.

Abstract: A computer-implemented method includes receiving an initial control flow graph (CFG) describing a project, where the project includes one or more programs. The initial CFG includes a plurality of graph nodes and a plurality of edges connecting the plurality of graph nodes to one another. Based on first profiling data, a first set of one or more graph nodes of the plurality of graph nodes of the initial CFG is selected as a first set of main nodes. The first profiling data describes a first execution history of the project. The initial CFG is simplified by generating a first final CFG, which includes the first set of main nodes and excludes one or more remaining nodes of the initial CFG that are not in the first set of main nodes.
