epoll in under layer block the libtorrent - epoll_wait on ARM platform #542

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago

On ARM platform, libtorrent is silently blocked by epoll_wait() function. If I 
attach it by gdb and use Ctrl+c to break and then continue it. It will 
continue. It works in this way time to time. When it is blocked, no message get 
printed for downloading and others alerts. So I can notice it is blocked.

It could be blocked on alert pop or network thread. The question is how to 
debug this issue?

Below is my code to get alerts.

    std::deque<alert*> alerts;
    p_libtorrent->session->pop_alerts(&alerts);
    std::string now = time_now_string();

    for (std::deque<alert*>::iterator i = alerts.begin()
        , end(alerts.end()); i != end; ++i)
    {
        bool need_resort = false;
        if (!::handle_alert(p_libtorrent, p_libtorrent->session, *i)) 
        {
            // if we didn't handle the alert, print it to the log
            std::string event_string;
            print_alert(*i, event_string);
            mesgDbg("alert : %s [%s]", event_string.c_str(), now.c_str());
        }
        delete *i;
    }
    alerts.clear();

GoogleCodeExporter commented 8 years ago

After a few hours investigation, I believe it is blocked when push below alerts:
block_finished_alert
block_downloading_alert

Still need more investigation.

GoogleCodeExporter commented 8 years ago

which version/branch of libtorrent are you testing?

If the hang happens on shutdown, it can be debugged by building with 
asio-debugging=on

I believe this is a dead lock. Let me explain below:
First thread - my client thread run below code:

 if (state_update_alert* p = alert_cast<state_update_alert>(a))
 {
        mDbg("state_update_alert begin");
        std::string now = time_now_string();
for (std::vector<torrent_status>::iterator i = p->status.begin();
i != p->status.end(); ++i)
{
            // debug
            session_status sess_stat = p_libtorrent->session->status();
       ///// <<<<< wait here as below message show

            mesg_Dbg((void*)p_libtorrent->p_access, "state update alert: %s
[%s - %s]", state_str[i->state],
                     add_suffix(sess_stat.download_rate, "/s").c_str(),
                     add_suffix(sess_stat.total_download).c_str()
                     );
        }
 }

Second thread - libtorrent thread (post alert - session thread, is this
from main thread?)

 bool peer_connection::add_request(piece_block const& block, int flags)
 {
    ....

if (t->alerts().should_post<block_downloading_alert>())
{
            LOGV("post block_downloading_alert begin");
t->alerts().post_alert(block_downloading_alert(t->get_handle(),
remote(), pid(), speedmsg, block.block_index, block.piece_index));
////// <<<<<< blocked here as below
            LOGV("post block_downloading_alert end");
}
        LOGV("pending_block begin");

    ....
 }

session_status session_impl::status() const
{
        LOGV("session status begin ...");
        ......
        }

session_status session::status() const
{
TORRENT_SYNC_CALL_RET(session_status, status);      <<<<< client wait for
libtorrent post block_downloading_alert done
return r;
}

Libtorrent(3265): post block_finiished_alert begin
Libtorrent(3265): push alert: block_finished_alert
Libtorrent(3265): post block_finiished_alert end

Libtorrent(3265): post block_downloading_alert begin    <<<<<<

Client(3265): access_torrent access: process alert begin ...
Client(3265): access_torrent access: process alert begin ... after pop
Client(3265): access_torrent access: handle_alert begin
Client(3265): access_torrent access: state_update_alert begin    <<<<<<

************************ dead lock here and go to below when ctrl+c
interrupt signal in GDB *******************

Libtorrent(3265): push alert: block_downloading_alert
Libtorrent(3265): post block_downloading_alert end   <<<<<<
Libtorrent(3265): pending_block begin
Libtorrent(3265): pending_block end
Libtorrent(3265): post block_finiished_alert begin
Libtorrent(3265): push alert: block_finished_alert
Libtorrent(3265): post block_finiished_alert end
Libtorrent(3265): session status begin ...                           <<<<<
client go into status()
Libtorrent(3265): session status before dht status ...
Libtorrent(3265): session status begin before get_status ...
Libtorrent(3265): session status begin after get_status ...
Libtorrent(3265): session status end
Client(3265): access_torrent access: state update alert: downloading
[571.kB/s - 81.6MB]

So client thread -> status() -> wait for  libtorrent thread -> wait for sth
(epoll_wait for some event)

I recently fixed a deadlock in UDP trackers in RC_0_16 (the fix is not released 
yet). This was the patch: http://dpaste.com/1446281/

If you post stack traces for all thread when this happens, I'm sure I could 
easily figure out what's happening and fix it.

i gdb, do: thread apply all bt full

would you mind doing that again, but with a build with debug symbols?

if you're building with boost-build, just add "debug-symbols=on" or just add 
"-g" to your gcc command line

boost version is 1_45. I will try to build new version for test.

GoogleCodeExporter commented 8 years ago

you might want to build without invariant-checks. It looks like the invariant 
checks are taking a very long time (is your ARM machine slower than a normal 
desktop by any chance?).

building with boost-build, specify "invariant-checks=off" or 
-DTORRENT_DISABLE_INVARIANT_CHECKS on gcc.

Test with invariant check disabled with boost 53 gave new crash. Then went
back to boost 45, just the same.
Can we change that cond.wait() to have  a time out value?

If you have any idea and let me do more test, please let me know. Thanks
very much!

Do you have two session objects?

my understanding of what you're observing is that a call to session::status() 
blocks indefinitely.

This indicates that the session's main thread is either not processing messages 
at all, is stuck in a dead-lock with some other thread, or it has so many 
messages to process and they take so long that it appears to be stuck 
indefinitely.

The thread(s) of interest are the ones that has session_impl::main_thread() in 
theirs stacks. Both of the ones in the backtraces you posted appear to be alive 
(i.e. they don't appear to be stuck in a dead-lock). One of them is waiting for 
messages to process (in epoll) whereas the other one is running an invariant 
check (which can be quite expensive and add up).

Would you mind posting the stack traces from your main thread and the 
session_impl::main_thread() stacks from a build without invariant checks?

GoogleCodeExporter commented 8 years ago

also, would you mind filing a separate issue for the crash you see with boost 
1.53?

Because the comment can't be too long, I post multiple times.

So we have a few threads:
1. two main thread from session impl (libtorrent need two?)
2. two disk io threads
3. two task_io_services threads
4. one app client thread  (call session->status() and blocked)

I put a few log message print in session and alert post to see if it works when 
client thread blocked and dead lock happening. There is no any message printed 
when it happens. Because alert post is done by main thread of session, it means 
it stops too.

I will put more log message in two main and task_io thread to see if they keep 
running.

Because session->status() is blocked by below code, does this help to find 
which thread should send signal to this condition wait?

#define TORRENT_WAIT \
    mutex::scoped_lock l(m_impl->mut); \
    while (!done) { m_impl->cond.wait(l); };

#define TORRENT_SYNC_CALL_RET(type, x) \
    bool done = false; \
    type r; \
    m_impl->m_io_service.dispatch(boost::bind(&fun_ret<type>, &r, &done, &m_impl->cond, &m_impl->mut, boost::function<type(void)>(boost::bind(&session_impl:: x, m_impl.get())))); \
    TORRENT_WAIT

    session_status session::status() const
    {
        TORRENT_SYNC_CALL_RET(session_status, status);
        return r;
    }

And I saw it was blocked within torrent_handle as below.

#define TORRENT_SYNC_CALL_RET(type, def, x) \
    boost::shared_ptr<torrent> t = m_torrent.lock(); \
    if (!t) return def; \
    bool done = false; \
    session_impl& ses = t->session(); \
    type r; \
    mutex::scoped_lock l(ses.mut); \
    ses.m_io_service.dispatch(boost::bind(&fun_ret<type >, &r, &done, &ses.cond, &ses.mut, boost::function<type(void)>(boost::bind(&torrent:: x, t)))); \
    t.reset(); \
    do { ses.cond.wait(l); } while(!done)

having two session_impl::main_thread and two disk threads definitely suggest 
that you construct two session objects, or at least that two get constructed 
somehow.

Is it the case that the main thread in the call to boost::shared_ptr::lock() 
does not make any progress? I noticed that both times it's in that function. If 
it's the case that it doesn't make progress you're hitting a more fundamental 
bug, probably in the hardware or compiler. The shared_ptr uses CAS operations 
for the reference counters, it's possible that your hardware does not support 
CAS operations or that your compiler generates invalid code for them. I would 
suggest you build with BOOST_AC_USE_PTHREADS defined. This will make shared_ptr 
use a mutex instead of atomic operations. If that works, it strongly indicates 
that this is the problem you have.

You may also want to try to run the boost.smart_ptr unit tests.

This issue is fixed by using BOOST_AC_USE_PTHREADS with boost 1_45 and 
libtorrent 0.16.12. 
There is another problem is caused by a static variable of session (forgot to 
comment out) which created more threads. It is just a mistake in my code. After 
remove this static variable, there was still a dead lock. The status() in 
client thread dispatch a task to task_io_service which never return done for 
some reason. And after apply  BOOST_AC_USE_PTHREADS, this is gone.
So, thank you very much for help. I will remember this.
