delphi – Sorting TDictionary by a key of Integer in ascending order – Stack Overflow

Posted by jpluimers on 2019/05/30

Great answer on [WayBack] delphi – Sorting TDictionary by a key of Integer in ascending order – Stack Overflow by J… comes down to this:

var
  LDictionary : TDictionary<Integer, string>;
  LArray : TArray<Integer>;
...
  LArray := LDictionary.Keys.ToArray();
  TArray.Sort<Integer>(LArray);

I was trying the wrong direction (functional approach like LArray := LDictionary.Keys.ToArray.Sort(); ), but the above procedural solution works.

TInterlocked.Exchange for interfaces?

Posted by jpluimers on 2019/05/29

Via [WayBack] TInterlocked.Exchange for interfaces? Since there is no System.SyncObjs.TInterlocked.Exchange overload for interfaces (and the Exchange versio… – Stefan Glienke – Google+

It has made it to this piece in [Archive.is] sglienke / Spring4D / source / Source / Reactive / Spring.Reactive.pas — Bitbucket:

class function TInterlockedHelper.Exchange<T>(var Target: T;
  const Value: T): T;
begin
  Result := Default(T);
  PPointer(@Result)^ := Exchange(PPointer(@Target)^, PPointer(@Value)^);
  if Assigned(Value) then
    Value._AddRef;
end;

It is similar to the TInterlocked.Exchange methods.

  • Shift+Ctrl+Alt+Enter for “Find Local References”.

No shortcut toggling anymore.

Useful settings for FastMM4 to tracking bottlenecks in multi-threaded memory allocation

Posted by jpluimers on 2019/05/23

Interesting thread that reminded me of the relatively new FastMM feature to track down lock contention and cope with it using release stacks:

[WayBack] I try use FastMM4 to tracking bottleneck in allocating memory. I was inspired by this Primož movie: https://www.youtube.com/watch?v=p-5mJyXvmrc When I… – Jacek Laskowski – Google+

The changes by Primož have added these two new conditional defines to the FastMM4 codebase:

These options are mutually exclusive.

This was the original post it got introduced in [WayBack] The Delphi Geek: Finding Memory Allocation Bottlenecks with FastMM4 and merged into the main repository.

FastMM introduction: [WayBack] The New Memory Manager In BDS 2006 – by Pierre le Riche.

It also taught me about [WayBack] RAMDisk – Software that Accelerates, Protects, Optimizes – Server Memory Products & Services – Dataram.

Primož stores his DCU files there: much faster than SSD, and far less wear on your SSD; see https://youtu.be/p-5mJyXvmrc?t=2675

Delphi XE8 introduced the dependency directive, but it’s not for Windows

Posted by jpluimers on 2019/05/21

Interesting thread that shows Delphi XE8 introduced a dependency directive: [WayBack] Just curious, in which version was the dependency directive introduced? As in procedure X; external ‘somelib’ dependecy ‘otherlib’; S… – Johan Bontes – Google+

It’s documented as of XE8: [WayBack] Procedures and Functions (Delphi) – RAD Studio: Specifying Dependencies of the Library

The earliest use I could find is in XE4 source C:\Program Files (x86)\Embarcadero\RAD Studio\11.0\source\IBX\IBIntf.pas
