stmtexecute

stmtexecute is a command-line tool and library component designed to execute transactional blocks within Software Transactional Memory (STM) runtimes. It provides an execution environment for code annotated as transactions, coordinating with the underlying STM to manage concurrency, isolation, and rollback. The tool is typically used to run, test, or benchmark transactional code paths within an application or a dedicated testing harness.

Architecturally, stmtexecute separates the transaction orchestration from application logic. The STM runtime handles versioning of shared objects, conflict detection, and commit or abort decisions, while stmtexecute invokes transactional blocks, propagates results to the caller, and collects metrics such as execution time and conflict counts. It often supports integration with multiple language bindings and can operate in both standalone and embedded modes.

Usage and capabilities vary by version, but common features include the ability to run single transactions or sequences of transactions, specify input data for transactions, and configure logging, instrumentation, and retry policies. The tool generally reports a transaction status (committed, aborted, or retried) and may emit detailed traces useful for debugging and performance tuning. It is commonly used in development, testing, and benchmarking contexts to study STM behavior under controlled workloads.

History and availability can differ across STM implementations, but stmtexecute is typically part of broader STM toolchains and is maintained by contributing communities or organizations within the STM ecosystem. It is distributed as a library and as a standalone CLI in many environments, with varying levels of documentation and community support.
