Detailed Description

A thread system whose mutex and condvar factories yield implementations that permit checking of lock invariants using DCheckLocked(). This can be wrapped around an unchecked implementation. This implementation checks invariants using CHECK (so does checking unconditionally). To check conditionally, do the wrapping depending upon the setting of NDEBUG. This is done by the Platform::CreateThreadSystem() factory by default, which is why the invariant checking method is called DCheckLock (Debug check lock) and not CheckLock.

Member Function Documentation

virtual ThreadId* net_instaweb::CheckingThreadSystem::GetThreadId ( ) const

inlinevirtual

Returns an object holding the current thread ID. The resultant object must be freed by the caller.

Implements net_instaweb::ThreadSystem.

virtual Mutex* net_instaweb::CheckingThreadSystem::NewMutex ( )

virtual

Makes a new mutex for this system.

See also CondvarCapableMutex::NewCondvar.

Implements net_instaweb::ThreadSystem.

virtual RWLock* net_instaweb::CheckingThreadSystem::NewRWLock ( )

virtual

This lock will provide following guarantee -

• Reader reentrant safe.
• Writer Priority, this ensures no writer starvation.

Implements net_instaweb::ThreadSystem.

virtual Timer* net_instaweb::CheckingThreadSystem::NewTimer ( )

virtual

Creates and returns a real-time timer. Caller is responsible for deleting.

Todo:

TODO(jmarantz): consider removing this and controlling timers separately.

Implements net_instaweb::ThreadSystem.
