Maybe mORMot can benefit of this "branch-free lomuto partition algorithm".

Sorting using the branchless Lomuto partition, however, is the clear winner by a large margin regardless of platform, backend, and input size.

@ab
I noticed that your version of FastMM4-AVX, that comes with mORMot, have some IFDEFs and corrections.

Do you will send a patch to original FastMM4-AVX? There are any bugfixes needed for Delphi 7?

Testing BorlndMM.dll replacement compiled with D7 and FastMM4-AVX.

After replacing the DLL I have noticed:
- Compilation is faster.
- Delphi D7 IDE don't hangs anymore when using code completion and code helpers.

Edit: I was using the original (from 2002!) BorlndMM.dll due to a reinstall of Delphi and didn't remember to replace de DLL.

Yes, please, end of discussion. D7 works. D7 have components that I don't want buy again in new versions.

Reinstall components is hell.

Even today, Delphi can't work as a ruby bundle or rust crate, and I can't have a dependency list neither a place to download them.

For years, all my programs .DPR always used this opening uses clause:

uses
  FastMM4, FastCode, FastMove,
  Windows, Forms,

Reading mORMot examples, I found

//   first line of uses clause must be   {$I SynDprUses.inc}
uses
  {$I SynDprUses.inc}
  Forms,

I did a comparision of mORMOt's version of FastMM4 and liked it. I will use the mORMot version.

But, what about FastCode and FastMove units? The optimizations of mORMot code will have better performance that the old FastCode, FastMove units? It's a drop-in replacement?

Maybe this can be useful for someone.

Found a bug today. Using D7 and the current git version.

When parsing the string/CSV '-1,25,0' after a call to CSVToRawUTF8DynArray(),  the CSV array will have only two elements: ('-1','25). The last element, '0' will be left out.

Code to reproduce:

     procedure BugCSVToRawUTF8DynArray;
     var
       CSV: TRawUTF8DynArray;
     begin
       CSVToRawUTF8DynArray('-1,25,0', ',', #0, CSV);
       Assert(Length(CSV) = 3);
     end;

I need to display this error list on a sort of a grid or equivalent control [Delphi 7].

The error list are like one array of [(ErrorCode, Int1, Int2, ErrorMsgStr)].

Arnaud, what is the best approach to get keys and values from a TSynDictionary instance?

I have a dictionary where the keys are Double and the values are integers. My objective is get the count of integers by key. And I am using this:

My HugeList[] is a TDoubleDynArray:

  D := TSynDictionary.Create(TypeInfo(TDoubleDynArray), TypeInfo(TIntegerDynArray));
  try
    for I := 0 to High(HugeList) do begin
        if D.FindAndCopy(HugeList[I], N) then
            N := N + 1
        else
            N := 1;
        D.AddOrUpdate(HugeList[I], N);
    end;
    SetLength(Keys, D.Keys.Count);  // get a copy of the keys        <--- this works, but
    D.Keys.Slice(Keys, D.Keys.Count);
    SetLength(Counts, D.Values.Count);  // get a copy of the values  <--- there are a better way?
    D.Values.Slice(Counts, D.Values.Count);
  finally
    D.Free;
  end;

Arnaud, if I declare a type to be used as a dictionary key in TSynDictionary:

TMyKey = record
           A, B: Double;
         end;
TMyKeyDynArray = array of TMyKey;

and initialize a TSynDictionary instance as

  D := TSynDictionary.Create(TypeInfo(TMyKeyDynArray), TypeInfo(TItensArray));

in a loop, we add itens to dictionary:

  K.A := SomeFuncionA;
  K.B := SomeFuncionB;
  if D.Exists(K) then { do something }
  else D.Add(K, SomeItem);

In the second pass of loop, I get a AV when call D.Exists().

Works when I change the key type to be a RawUTF8 or a variant.

This is by design?
