Sorry to spam the list, but here is V4. After building V3 on 3 platforms without error and submitting, the compilers on platforms 4 and 5 complained about a variable declaration. (sigh) [] fix declaration after first statement [] add -DNO_UNIX_SOCKETS to BASIC_CFLAGS when NO_UNIX_SOCKETS is defined in the Makefile.
----------------------------------------------------------------------------
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.
