This change continues the thread naming work from #5691 and #5758, which enables more useful lock contention profiling by ensuring threads/jobs have short, stable, human-readable names (rather than being truncated/failing due to OS limits). This changes diagnostic naming only (thread names and job/load-event labels), not behavior.
Specific modifications are:
* Shortens all thread/job names used with `beast::setCurrentThreadName`, so the effective Linux thread name stays within the 15-character limit.
* Removes per-ledger sequence numbers from job/thread names to avoid long labels. This improves aggregation in lock contention profiling for short-lived job executions.
This change renames all occurrences of `namespace ripple` and `ripple::` to `namespace xrpl` and `xrpl::`, respectively, as well as the names of test suites. It also provides a script to allow developers to replicate the changes in their local branch or fork to avoid conflicts.
Per XLS-0095, we are taking steps to rename ripple(d) to xrpl(d).
This change specifically removes all copyright notices referencing Ripple, XRPLF, and certain affiliated contributors upon mutual agreement, so the notice in the LICENSE.md file applies throughout. Copyright notices referencing external contributions remain as-is. Duplicate verbiage is also removed.
The codebase is filled with includes that are unused, and which thus can be removed. At the same time, the files often do not include all headers that contain the definitions used in those files. This change uses clang-format and clang-tidy to clean up the includes, with minor manual intervention to ensure the code compiles on all platforms.
This is a refactor aimed at cleaning up and simplifying the existing
job queue.
As of now, all jobs are cancelled at the same time and in the same
way, so this commit removes the per-job cancellation token. If the
need for such support is demonstrated, support can be re-added.
* Revise documentation for ClosureCounter and Workers.
* Simplify code, removing unnecessary function arguments and
deduplicating expressions
* Restructure job handlers to no longer need to pass a job's
handle to the job.
The existing calculation would limit the maximum number of threads
that would be created by default to at most 6; this may have been
reasonable a few years ago, but given both the load on the network
as of today and the increase in the number of CPU cores, the value
should be revisited.
This commit, if merged, changes the default calculation for nodes
that are configured as `large` or `huge` to allow for up to twelve
threads.
