           Summary: static ~this() cannot be used to shutdown threads
           Product: D
           Version: 2.020
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: ludwig@informatik.uni-luebeck.de


In src/druntime/src/compiler/dmd/dmain2.d:301 thread_joinAll() is called before
_moduleDtor(). This makes it impossible to perform thread shutdown inside of a
module destructor because the thread_joinAll() call will wait indefinitely if
there are still threads waiting for a shutdown signal.

Moving thread_joinAll between _moduleDtor() and gc_term() should fix the issue.

(not sure if this should go here or into the trac issue tracker for
druntime...)

It's not unlikely that a thread may depend on static data, so by moving thread_joinAll() until after the module dtors are called we would be pulling the rug out from under these threads.  Instead, I suggest making threads that interact with the module shutdown process into daemon threads by using the "isDaemon" property.  These threads are ignored during thread_joinAll() and, left alone, will run until the process ends.

Ah OK.. I didn't know about that property. That approach is definitly workable, albeit maybe a little non-obvious. THanks for the quick feedback.
