Ævar Arnfjörð Bjarmason	48f68715b1	tr2: stop leaking "thread_name" memory Fix a memory leak introduced in `ee4512ed48` (trace2: create new combined trace facility, 2019-02-22), we were doing a free() of other memory allocated in tr2tls_create_self(), but not the "thread_name" "struct strbuf".

Jeff Hostetler	5fdae9d3be	trace2: fix tracing when NO_PTHREADS is defined Teach trace2 TLS code to not rely on pthread_getspecific() when NO_PTHREADS is defined. Instead, always assume the context data of the main thread. Signed-off-by: Jeff Hostetler <jeffhost@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	6 years ago
Jeff Hostetler	a089724958	trace2: refactor setting process starting time Create trace2_initialize_clock() and call from main() to capture process start time in isolation and before other sub-systems are ready.

Jeff Hostetler	ee4512ed48	trace2: create new combined trace facility Create a new unified tracing facility for git. The eventual intent is to replace the current trace_printf* and trace_performance* routines with a unified set of git_trace2* routines. In addition to the usual printf-style API, trace2 provides higer-level event verbs with fixed-fields allowing structured data to be written. This makes post-processing and analysis easier for external tools. Trace2 defines 3 output targets. These are set using the environment variables "GIT_TR2", "GIT_TR2_PERF", and "GIT_TR2_EVENT". These may be set to "1" or to an absolute pathname (just like the current GIT_TRACE). * GIT_TR2 is intended to be a replacement for GIT_TRACE and logs command summary data. * GIT_TR2_PERF is intended as a replacement for GIT_TRACE_PERFORMANCE. It extends the output with columns for the command process, thread, repo, absolute and relative elapsed times. It reports events for child process start/stop, thread start/stop, and per-thread function nesting. * GIT_TR2_EVENT is a new structured format. It writes event data as a series of JSON records. Calls to trace2 functions log to any of the 3 output targets enabled without the need to call different trace_printf* or trace_performance* routines.
