Subject: [PATCH 0/9] Trace2 timers and counters and some cleanup
Date: Tue, 04 Oct 2022 16:19:58 +0000 [thread overview]
Message-ID: <pull.1373.git.1664900407.gitgitgadget@gmail.com> (raw)
This patch series add stopwatch timers and global counters to the trace2
logging facility. It also does a little housecleaning.
This is basically a rewrite of the series that I submitted back in December
2021: [1] and [2]. Hopefully, it addresses all of the concerns raised back
then and does it in a way that avoids the issues that stalled that effort.
First we start with a few housecleaning commits:
* The first 2 commits are unrelated to this effort, but were required to
get the existing code to compile on my Mac with Clang 11.0.0 with
DEVELOPER=1. Those can be dropped if there is a better way to do this.
* The 3rd commit is in response a concern about using int rather than
size_t for nr and alloc in an ALLOC_GROW() in existing trace2 code.
* The 4th commit cleans up my use of the term "TLS" in my thread code.
* The 5th and 6th commits (hopefully) clear up the misunderstandings around
the thread_name variable in my thread context structures. My earlier
attempts to clean and clarify this led to most of the controversies in
the earlier patch series. Hopefully, these 2 commits will improve the
clarify matters.
* The 7th commit cleans up a mostly obsolete section in the trace2 API
documentation.
Finally, the last 2 commits add the stopwatch timers and the global
counters.
