OmniThreadLibrary 3.07.3

TL;DR: Update OmniThreadLibrary now!

A nasty bug was found in the DSiWin32 library. It causes the DSiTimeGetTime64 function to work incorrectly when called from multiple threads at the same time. As this function is central to time measurement in the OmniThreadLibrary, it was essential to release new, fixed version.

This version also contains two small enhancements.

  • SetTimer method now accepts TProc and TProc timer methods.
  • IOmniTask implements method InvokeOnSelf which can be used to schedule anonymous function execution from a task back to self.  

As usual, you can get OmniThreadLibrary from GitHub (3.07.3HEAD), download the zip, install it with GetIt (soon, I hope) or with Delphinus (already).

Damn, multithreading is hard!

OmniThreadLibrary 3.07.2

This is just a small update which adds few helpful methods. Although the change log mentions a potentially breaking change I don't think this will affect anybody. (And if you are not sure, you can enabled backward-compatible behaviour by adding one line to the code.)

I have also (finally) found some time to work on The book. It is now fully up to date (all OmniThreadLibrary features are documented on its whooping 293 pages) and is only missing one or two introductory chapters.

As usual, you can get OmniThreadLibrary from GitHub (3.07.2, HEAD), download the zip, install it with GetIt (soon, I hope) or with Delphinus (already).

Change log follows after the break.

OmniThreadLibrary 3.07.1

This update brings only few small changes. The biggest of them is support for the Delphi 10.2 Tokyo.

You can get it as a zipped download, git checkout, via Delphinus, and via GetIt.

Forward record declaration

Forward declaration is not really a new concept. It was already present in the original Wirth Pascal where it allowed the programmer to do one thing and one thing only – call procedure A from procedure B and procedure B from procedure A. Remember – in ye olde times of good old Pascal we had no interfaces, no classes, no units … just procedures and functions.

Because the code tells more than thousand words, here’s an example (still perfectly valid in modern Object Pascal).

procedure ProcA; forward;

procedure ProcB;
begin
  ProcA;
end;

procedure ProcA;
begin
  ProcB;
end;

OmniThreadLibrary 3.07 beta + plans for OmniThreadLibrary 4.0

It is almost time for a new release! If you’d like to see what 3.07 will contain – or if you just want to test it before it is out – click here.

[If you are a serious OTL user - and especially if you are using pre-Seattle Delphi - please test your program(s) with the beta release. Thanks!]

I have started work on OTL 4.0 which will (fingers crossed) fully support cross-platorm work. Yup, it will work on all platforms that Delphi can compile for! Multiplatform support was implemented by Sean B. Durkin so if OTL/Mobile is something you were waiting for a long time, go to OmniThreadLibrary-For-Mobile Google+ community and express your gratitude.
