in src/event/ngx_event_openssl.c:1907, i found function
ngx_ssl_clear_error() call openssl function ERR_peek_error() in a
while loop, intend to clear global error code queue,
but according to openssl's documents and source code, ERR_peek_error() will not
pop the first error code , and it does not modify the queue.
so it looks like this will cause a busy loop.
is my understanding correct?
reference:
nginx source code
"
static void
ngx_ssl_clear_error(ngx_log_t *log)
{
while (ERR_peek_error()) {
ngx_ssl_error(NGX_LOG_ALERT, log, 0, "ignoring stale global SSL error");
}
ERR_clear_error();
}
"
openssl source code:
https://github.com/openssl/openssl/blob/master/crypto/err/err.c#L770
