46 | //
|
---|
47 | // Threads:
|
---|
48 | // --------
|
---|
49 | // In most cases Js* and other calls to native C++ code could be wrapped
|
---|
50 | // with an Unlocker to allow possible other JavaScipt 'threads' to run
|
---|
51 | // during that time. However, all of these calls should take much less than
|
---|
52 | // the preemption time of 10ms, so it would just be a waste of tim.
|
---|
53 | //
|
---|
54 | // Termination:
|
---|
55 | // ------------
|
---|
56 | // Each thread running V8 code needs to be signalled individually for
|
---|
57 | // termination. Therefor a list of V8 thread ids is created.
|
---|
58 | //
|
---|
59 | // If termination has already be signalled, no thread should start running
|
---|
60 | // anymore (thy could, e.g., wait for their locking). So after locking
|
---|
61 | // it has to be checked if the thread was terminated already. Note
|
---|
62 | // that all calls to Terminate() must be locked to ensure that fThreadId
|
---|
63 | // is correct when it is checked.
|
---|
64 | //
|
---|
65 | // The current thread id must be added to fThreadIds _before_ any
|
---|
66 | // function is called after Locking and before execution is given
|
---|
67 | // back to JavaScript, e.g. in script->Run(). So until the thread
|
---|
68 | // is added to the list Terminate will not be executed. If Terminate
|
---|
69 | // is then executed, it is ensured that the current thread is
|
---|
70 | // already in the list. If terminate has been called before
|
---|
71 | // the Locking, the check for the validiy of fThreadId ensures that
|
---|
72 | // nothing is executed.
|
---|
73 | //
|
---|
74 | // Empty handles:
|
---|
75 | // --------------
|
---|
76 | // If exceution is terminated, V8 calls might return with empty handles,
|
---|
77 | // e.g. Date::New(isolate). Therefore, the returned handles of these calls have to
|
---|
78 | // be checked in all placed to avoid that V8 will core dump.
|
---|
79 | //
|
---|
80 | // HandleScope:
|
---|
81 | // ------------
|
---|
82 | // A handle scope is a garbage collector and collects all handles created
|
---|
83 | // until it goes out of scope. Handles which are not needed anymore are
|
---|
84 | // then deleted. To return a handle from a HandleScope you need to use
|
---|
85 | // Close(). E.g., String::Utf8Value does not create a new handle and
|
---|
86 | // hence does not need a HandleScope. Any ::New will need a handle scope.
|
---|
87 | // Forgetting the HandleScope could in principle fill your memory,
|
---|
88 | // but everything is properly deleted by the global HandleScope at
|
---|
89 | // script termination.
|
---|
90 | //
|
---|
91 | // Here is another good reference for v8, also containing some
|
---|
92 | // good explanations for the meaning of handles, persistent handles
|
---|
93 | // and weak handles: http://create.tpsitulsa.com/wiki/V8_Cookbook
