Why not make that class public? I think it will become necessary on its own as
well.

[Felix Dahlke, 2013/04/03 16:27:59]

It is public, just nested in Thread. Would you prefer to have it on the top
level? Don't have a strong opinion myself.

[Wladimir Palant, 2013/04/03 19:30:16]

AdblockPlus::Thread::Mutex just sounds wrong - it isn't directly related to
threads. AdblockPlus::Threading::Mutex on the other hand would be fine but then
you would need AdblockPlus::Threading::Thread as well - way too much to write.
Better top level I guess, there is little potential for conflict anyway.
Condition will have to be renamed into ConditionVariable however.

Sure, moved them to the top level.

+    {
+    public:
+#ifdef WIN32
+      CRITICAL_SECTION nativeMutex;
+#else
+      pthread_mutex_t nativeMutex;
+#endif
+
+      Mutex();
+      ~Mutex();
+      void Lock();
+      void Unlock();
+    };
+
+    class Condition
+    {
+    public:
+      Condition();
+      ~Condition();
+      void Wait(Mutex& mutex);
+      void Signal();
+
+    private:
+#ifdef WIN32

CONDITION_VARIABLE nativeCondition; missing here?

[Felix Dahlke, 2013/04/03 16:27:59]

Yes, somehow messed up the patch it seems, Oleksandr fixed that.

+#else
+      pthread_cond_t nativeCondition;
+#endif
+    };
+
+    virtual ~Thread();
+    virtual void Run() = 0;
+    void Start();
+    void Join();
+
+  private:
+#ifdef WIN32
+    HANDLE thread;

[Wladimir Palant, 2013/04/03 13:14:47]

Rename this into nativeThread for consistency?

[Felix Dahlke, 2013/04/03 16:27:59]

Absolutely, done.
