# There are multiple trace2 targets: normal, perf, and event.
# Trace2 events will/can be written to each active target (subject
# to whatever filtering that target decides to do).
# This script tests the normal target in isolation.
#
# Defer setting GIT_TR2 until the actual command line we want to test
# because hidden git and test-tool commands run by the test harness
# can contaminate our output.
# Enable "brief" feature which turns off "<clock> <file>:<line> " prefix.

# Basic tests of the trace2 normal stream. Since this stream is used
# primarily with printf-style debugging/tracing, we do limited testing
# here.
#
# We do confirm the following API features:
# [] the 'version <v>' event
# [] the 'start <argv>' event
# [] the 'cmd_name <name>' event
# [] the 'exit <time> code:<code>' event
# [] the 'atexit <time> code:<code>' event
#
# Fields of the form _FIELD_ are tokens that have been replaced (such
# as the elapsed time).
# Verb 001return
#
# Implicit return from cmd_<verb> function propagates <code>.
