td_thr_info - get information on a thread
Currently a subset of td_thread_info_t is documented. This version
describes thread_addr and thread_state.

This test contains threads1 test that:
Asserts that td_thr_iter() call without extra logic works
This tests fails and is linked with gnats:

At the moment this test does nothing except reports failure from td_open()
for overloaded (implemented) dummy1_proc_lookup() (.proc_lookup from
td_proc_callbacks_t) of the following form:
static int
dummy1_proc_lookup(void *arg, const char *sym, caddr_t *addr)
{
return TD_ERR_ERR;
}
This file and directory with tests is placeholder for new ones, without
further need to alter mtree and distribution sets.
The libpthread_dbg interface and library is used by gdb(1) to handle

Move out wait(2) specific tests from t_ptrace and put them to t_ptrace_wait
Add generic code fragments to reuse the same source-code for every member
of the wait(2) family, namely:
- wait(2)
- waitpid(2)
- waitid(2)
- wait3(2)
- wait4(2)
- wait6(2)
Currently in the new test-suite there are the following tests:
- traceme1
- traceme2
- traceme3
- traceme4
- attach1
Not all tests are possible to be executed against every wait(2)-like
interface, therefore they will be disabled in such case. Currently this
limits attach1 to waitpid(2), waitid(2), wait4(2), wait6(2), while the
other tests (traceme 1-4) run with all of the interfaces.
The construct of this file is dedicated for addition of new tests in the
close future.
As of now all of the tests pass correctly.
Thanks for Robert Elz for suggestions on improving the code (earlier draft
of this new form).

The t_wait_noproc test checks whether wait(2)-family of functions return
error and set ECHILD for lack of childs.
The t_wait_noproc_wnohang adds to options (except wait(2), wait3(2)) new
parameter WNOHANG and verifies that error is still signaled and errno set
to ECHILD.
Currently t_wait_noproc_wnohang reports failures, these have been marked as
expected and referenced to PR standards/51606.
The problem report is authored by Robert Elz, and the initial regression
has been notified by Nicolas Joly.
Remove redundant test in tests/lib/libc/sys/t_wait for wait6(2) with no
WNOHANG specified.

This test is a placeholder for further checks of the native ptrace(2)
function calls.
XXX: Is it safe to call ATF functions from a child? FreeBSD seems to

This test is a clone on t_mutex with additional two tests for timed-mutex
specific block.
All simple-mutex (not with the timed property according to the C11 wording)
specific tests are covered by pthread_mutex_timedlock(3) with parameter
ts_lengthy of sufficiently large tv_sec value (right now UINT16_MAX). If,
a test will hang, it won't wait UINT16_MAX seconds, but will be terminated
within the default timeout for ATF tests (right now 300 [sec] in my
NetBSD/amd64 setup).
This test was inspired by a classic selflock test failure of
pthread_mutex_timedlock(3) of the following form:
#include <assert.h>
#include <errno.h>
#include <pthread.h>
#include <stdio.h>
#include <time.h>
int main(int argc, char **argv)
{
pthread_mutex_t mtx;
struct timespec ts;
ts.tv_sec = 0;
ts.tv_nsec = 1000;
printf("ts{.tv_sec = %d, .tv_nsec=%ld}\n", ts.tv_sec, ts.tv_nsec);
fflush(stdout);
printf("mtx_init\n");
assert(pthread_mutex_init(&mtx, NULL) == 0);
printf("mtx_lock\n");
assert(pthread_mutex_lock(&mtx) == 0);
printf("mtx_timedlock\n");
assert(pthread_mutex_timedlock(&mtx, &ts) == ETIMEDOUT);
printf("mtx_unlock\n");
assert(pthread_mutex_unlock(&mtx) == 0);
printf("mtx_destroy\n");
assert(pthread_mutex_destroy(&mtx) == 0);
return 0;
}
Current NetBSD implementation wrongly hangs on this test.
The issue was detected during development of the C11 portable threads.
My local tests in chroot presents that the are further issues:
t_timedmutex (21/25): 10 test cases

timedmutex2: [301.123081s] Failed: Test case timed out after 300 seconds

I'm also receiveing the same failure in the mutex6 test in t_mutex, so
there might be a false positives due to local chroot(8) issues.
