I'm so sorry Pavlov.

Many people from my country are with your. I just wait that the world rest can help to Ukraine.

I agree with prefixing the framework with TSyn*, historically Delphi third party frameworks have used this. Even more, functions and procedure they should have a prefix, but thats is more complex for compatibility. It's just another opinion.

Hi @ab, I tried compile LogView.lpi with Laz 2.0.8/FPC 3.2.0 and have error in SynMemoEx.pas:

  RAEditorCompletionChars: set of AnsiChar =
    [#8, '_', '0'..'9', 'A'..'Z', 'a'..'z'];
  Separators: set of AnsiChar =
    [#0, ' ', '-', #13, #10, '.', ',', '/', '\', ':', '+', '%', '*', '(', ')',
    ';', '=', '{', '}', '[', ']', '{', '}', '|', '!', '@', '"']; 

the '{', '}' is duplicated.


  • SynMemoEx.pas(567,40) Error: Identifier not found "TCreateParams" in TCustomMemoEx in Laz 2.0.8 / FPC 3.2.0

  • With Delphi 10.3 no error is raised by the compiler (either duplicated entry and TCreateParams.

I thought that LogView was FPC/Windows compatible, my mistake.

Best regards.

I had similar needs but migrating from 3tier (with RemObjects) to 3tier (with mORMot). I implemented TSynRestDataset but using full mORMot features -not Indy, not OpenSSL, mORMot validators- (see https://synopse.info/forum/viewtopic.php?id=2712), we make small adaptations in out client applications (5, 10, 15 years) and all works fine.

#20 Re: mORMot Framework » Revision 2.x of the framework » 2020-03-09 12:09:06

I agree with @macfly, version 2 should be breaking change this way the migration will require the source code update.

on the other hand, ORM data response could be a class that could be replaced by other, for example for return in OData format ?


#21 Re: mORMot Framework » Compatibility problem between AESCBC 256 mORMot and C# » 2020-03-07 17:24:12

#22 Re: mORMot Framework » Compatibility problem between AESCBC 256 mORMot and C# » 2020-03-06 20:45:19

Hi @ab, I found the problem the compatibility (or not perhaps is by design):


constructor TAESAbstract.Create(const aKey; aKeySize: cardinal);
   if (aKeySize<>128) and (aKeySize<>192) and (aKeySize<>256) then
    raise ESynCrypto.CreateUTF8('%.Create(aKeySize=%): 128/192/256 required',[self,aKeySize]);
  fKeySize := aKeySize;
  fKeySizeBytes := fKeySize shr 3;
  MoveFast(aKey,fKey,fKeySizeBytes); <<<--- (1)

(1) if the key is, for example, "12345678" the byte array TAESKey should be:

[49, 50, 51, 52, 53, 54, 55, 56, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]

in other words, the rest of array should be completed with zeroes but is filled with other values that are valids. For workaround I added Key as property in TAESAbstract with read/write and after create I refilling with correct data and it works.

Can you tell me if this behavior is by design or bug ?

I removed Key property from TAESAbstract and implemented TAESAbstrackHack for accessing fKey protected member.
I don't know how patch MoveFast for non-filling with invalid values the rest of byte array. I think that Create constructor should have extra parameter with length of key text.


#23 Re: mORMot Framework » Revision 2.x of the framework » 2020-03-04 16:24:10

Thanks @ab, my intention is move to FPC but out base code is huge and much UI with DevEx and other visual third party components, all these tasks take time and we are very small team. We have not Delphi 2007 license.

#24 Re: mORMot Framework » Revision 2.x of the framework » 2020-03-04 13:28:36

I agree at all, except excluding Delphi 7 because all our projects are developed with it and, unfortunately, with third party components. I initiated conversations with my boss for migrating UI to web and use FPC as tool for backend development, but that's something that takes time. Maybe support for Delphi 7 for a few years (you decide how long) will be fantastic.

Excellent idea of use the semantic versioning.

Units splitting should be for functionality in my opinion, for example SynJSON with all related support for JSON handling.

Maybe this thread shoud be post as "sticky".

I need to generate a key using AES CBC 256 PKCS7 encryption for a .Net C# application that use this key for password when connection to database. The key have the form IV.KEY and is stored in a config file. I have the following code to generate the key in that way.

  lKey: TBytes;
  lIV: TAESBlock;
  lText, lTextEncrypted, lIVText: RawByteString;
      // edtKey.Text is KEY
      // edtSource.Text is TEXT TO ENCRYPT
      SetLength(lKey, Length(edtKey.Text));
      SynCommons.HexToBin(Pointer(edtKey.Text), @lKey, Min(Length(edtKey.Text),SizeOf(lKey)));
      RawByteStringToBytes(RawByteString(edtKey.Text), lKey);
      lAESCBC := TAESCBC.Create(lKey, CRYPT_KEY_SIZES[2]{=256});
        lText := StringToUTF8(edtSource.Text);
        lAESCBC.IV := lIV;
        lTextEncrypted := SynCommons.BinToBase64(lAESCBC.EncryptPKCS7(lText));
        lIVText := SynCommons.BinToBase64(@lAESCBC.IV, SizeOf(lAESCBC.IV));
        edtDest.Text := UTF8ToString(lTextEncrypted)+'.'+lIVText;

and the key generated with the above code

TEXT TO ENCRYPT=text to encrypt

oTfXA3+lm6aiOaGYjCsk+Q==.OX0qIq1iSEMhTdw/fl0ehg== (the dot is a separator)

raise an exception <b>Padding is invalid and cannot be removed.</b>

For testing I'm using dotfiddle.net in https://dotnetfiddle.net/tlO25C

What's wrong ?


#28 Re: mORMot Framework » Interfaced method syncronisation » 2019-12-20 14:37:16

sicShared works this way but then another mothods are also blocked.

Using lock/unlock inside the endpoint of interface service does not block other endpoints of the interface service.

I understand the warning comment but I downloaded, with FPCUpDeluxe, the trunk version (Lazarus 2.1.0 and FPC 3.3.1) ergo the revision is not that old.
