cannot stop main thread when running on android

Open whcjb opened this issue 5 years ago • 8 comments

hello, sorry to disturb. i use the dbm to run multi-threads app on android, but when the created threads exit, the main thread hanged on a basic_block loop all the time,. Then i use strace to see the syscall, found that the main thread last syscall_no is 98, which is futex, so, how to solve the problem, need your help, thanks.

Hi,

That sounds like an issue specific to your application. Any chance you could share the executable with us so we can debug it?

Thanks

hi，lgeek. it's not the application's error. the application runs well on android or linux. but it will hang when use dbm mt on android. it runs well on arm-linux using dbm mt, mt is the executable file name.

The application code is simple, just create two threads and use pthread_join to wait. the code here.

#include <pthread.h>
#include <stdlib.h>
#include <unistd.h>
void print_message_func(void *ptr);

int main()
{
int tmp1,tmp2;
void *retival;
pthread_t thread1;
pthread_t thread2;
char *message1 = "thread1";
char *message2 = "thread2";

int ret_thread1,ret_thread2;
ret_thread1 = pthread_create(&thread1,NULL,(void *)&print_message_func,(void *)message1);
ret_thread2 = pthread_create(&thread2,NULL,(void *)&print_message_func,(void *)message2);
tmp1 = pthread_join(thread1,&retival);
tmp2 = pthread_join(thread2,&retival);
}

void print_message_func(void *ptr)
{
    int i;
    sleep(10);
}

i use cross-compile gcc aaarch64-linux-android-gcc -o mt mt.c to compile the multi-threads appication mt.c, the ndk version is 20. after several days' error location, i have found that when use strace to ngrab the syscalls strace -f dbm mt on an android shell terminal, the error section of the log is this

from the log, i found that when the tid 4995 exit, the thread 4993 give a syscall [pid 4993] futex(0x7bfff7cd60, FUTEX_WAIT, 4995, NULL <unfinished ...> and it's the last record of pid 4993, so i guess the tid 4993 isn's noticed when 4995 exiting, the 4993 pending all the time.

the same application compiled runing in arm-linux is well with no error, dbm mt, the syscall strace is like this.

sorry that the binary file can't be uploaded, but you can compile the .c file, it;s the same. i have no idea how to debug next, it's good on arm-linux, but the error above on android. Thanks a lot.

it is the same error when run dbm geekbench_aarch64, the strace is the same that the main thread wait for the first child thread to exit which has already exited. the test is on android.

i tested that the dbm runs well when comment the line tmp1 = pthread_join(thread1,&retival);

so the error come from the futex(wait), or the inconnection between the futex(wake) and futex(wait). please help.

@whcjb @lgeek I have the same issue. After some investigation, I think the problem may be at this line, we can't join a thread if it is not attachable?

Thanks both of you. @amimo that makes sense, but nevertheless I can't reproduce the behavior described here on GNU/Linux. I suspect it's a difference in Android's pthreads implementation compared to glibc, I'll take a closer look.

Since MAMBO is linked statically, it will be using the standard library of the system it's compiled on, not of the host machine. This zip archive contains the master head I've built on an Arch Linux ARM system. This executable is running the example provided by @whcjb (also compiled on Arch and linked statically) correctly on an Android device.

It would be useful to know if this MAMBO binary can run @whcjb's example compiled with the Android toolchain without hanging.

This MAMBO built can exit normally running @whcjb's example compiled with the Android toolchain.

Since it's an old issue and I have no way of testing it at the moment, I'm going to close it in the effort to clean up the repo. If anyone still requires this fix, please re-open the issue and I can look into it.
