#9943

[heyuanjie87]

pipe_tc需要打开 components/libc下的#define RT_USING_POSIX_PIPE

msh />pipe_tc
msh />hello, world #1
hello, world #2
hello, world #3
{Test PASSED}

[heyuanjie87]

pthread_tc/pthread_getschedparam/1-2失败原因为smart还不支持调整policy

[heyuanjie87]

sched_tc/sched_get_priority_max/2-1: https://github.com/bminor/musl/blob/master/src/sched/sched_get_priority_max.c
这个函数在musl中没设置errno

[heyuanjie87]

pthread_tc/pthread_cancel/2-3：需要同步musl中pthread_cancel.c到最新版
增加了如下代码

static void cancel_handler(int sig, siginfo_t *si, void *ctx)
{
	if (self->cancelasync) {
		pthread_sigmask(SIG_SETMASK, &uc->uc_sigmask, 0);
		__cancel();
	}
}

更改后qemu中测试成功

msh />cd pthread_cancel/
msh /pthread_cancel>2-3
msh /pthread_cancel>{Test PASSED}

msh /pthread_cancel>
