Subject: [PATCH v3 00/14] Trace2 tracing facility
Date: Wed, 30 Jan 2019 11:51:04 -0800 (PST)
Message-ID: <pull.108.v3.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.108.v2.git.gitgitgadget@gmail.com>

V3 addresses: [] re-fix the trace2 tests using an inline environment
variable rather than exporting and unsetting. [] overhaul the design
document to include prototype declarations and more file format information.
[] incorporate most of the suggestions from clang-format. [] add ability to
trace to a unix domain socket. [] added forward declarations suggested by
Ramsay. [] rebased onto current master to fixup conflict with
sb/submodule-recursive-fetch-gets-the-tip that was merged yesterday.


----------------------------------------------------------------------------

V2 addresses: [] "jh/trace2" bad interaction with "js/vsts-ci" in "pu". []
coccinelle warnings in trace2/tr2_tgt_perf.c reported during CI testing.


----------------------------------------------------------------------------

This patch series contains a greatly refactored version of my original
Trace2 series [1] from August 2018.

A new design doc in Documentation/technical/api-trace2.txt (in the first
commit) explains the relationship of Trace2 to the current tracing facility.
Calls to the current tracing facility have not been changed, rather new
trace2 calls have been added so that both continue to work in parallel for
the time being.
