    • Faster and more lightweight than the TMultiReadExclusiveWriteSynchronizer (TMREW)
    • Works across all platforms (TMEW was a simple critical section on some)

  • 2020.09.08 Blog by Marco Cantu New TLightweightMREW Record in RAD Studio 10.4.1

    • The new TLightweightMREW record wraps native POSIX APIs, and it is a better replacement in most cases.
    • It has been implemented as a managed record to further reduce the need of creating and freeing it.
    • Supported features across all platforms:
      • If any thread holds a read lock then any other thread can also acquire a read lock while no one can acquire a write lock.
      • If any thread holds a write lock then no thread can acquire a read nor a write lock.
      • If a thread holds a read lock, it can acquire another read lock again before the first read lock is released (recursion).
      • If a thread holds a write lock, it cannot acquire another write lock
    • The following behavior depends on the operating system:
      • If at least one reader is always active, a writer may never get the lock (starvation)
      • If the same thread tries to recursively acquire a write lock two times, the application will deadlock on Windows but raise an exception on POSIX systems.

  • 2020.09.07 Blog by David Millington New for Delphi Code Insight in 10.4.1

    • Code Completion includes items that start with your typed text, but also that contains your typed text. Now this text is underlined by default in the list of results (see image below)
    • Four new settings added to Insight Options (see image below):
      • List all symbols that start with the filter first
      • Select shortest matching symbol
      • Filter text is underlined
      • Show symbols that contain filter
    • To reproduce Code Insight behavior in previous releases of Delphi, keep the first setting on and turn the rest off.
