Waiting to lock: mutex.lock(function () { console.log('We got the lock!'); // do stuff mutex.unlock(); }); Waiting to lock, with timeout: mutex.timedLock(5000, function (error) { if (error) { console.log('Could not get the lock within 5 seconds, so gave up'); } else { ...
下面的patch 可以把lock的owner 信息在ftrace 中记录,并且在systrace 中显示出来,可以加快对问题的debug 添加下面的patch 后 index 851fc3d..d75fe2a --- a/libc/bionic/pthread_mutex.cpp +++ b/libc/bionic/pthread_mutex.cpp @@ -44,6 +44,9 @@ #include "private/bionic_time_conversions.h" #inclu...
lock函数和tryLock函数都是用于锁定对象,但他们之间有一定的区别: lock函数是阻塞的,因为它调用WaitForSingleObject函数时传递的第二个参数是INFINITE,表示无限等待下去...调用lock或者tryLock后,都需要调用unlock来解锁。...status_t Mutex::lo...
Nativesync/Mutexandsync/RWMutexare very powerful and reliable. However, it became a disaster if the lock was not released as expected. Or, someone was holding the lock too long at the peak time leading whole system blocked. Dealing with those cases,go-lockimplementsTryLock,TryLockWithTimeoutand...
