    I found a few more units with RTTI and was able to further reduce the utilities from the Localizer project. Now the numbers are: kdlscan.exe was 742 400 bytes, now 355 840 bytes, -52% lngupdate.exe was 727 040 bytes, now 277 504 bytes, -62% I also tested one of my applications with and without RTTI. Application: Windows 32-bit utility, VCL, memory tables, RichEdit components, string processing. I measured only the speed of text processing, not the speed of launching the application. I have to say, in my case there is no gain in performance after the removal of RTTI. Test Application Executable File Size, bytes Processing time, best run, s RTTI enabled 4 777 472 62 RTTI disabled 3 300 864 61 Difference, % -31% -2% Probably, the tested program is too small, and can fit in the processor's cache entirely in both cases.

    Releasing memory devoted to arrays

    Kryvich replied to Gary Mugford's topic in General Help

    If you decide to go with TDictionary<string, TYourData>, here is examples how to create, initialize, use and free it: http://docwiki.embarcadero.com/CodeExamples/Tokyo/en/Talk:Generics_Collections_TDictionary_(Delphi).

    Releasing memory devoted to arrays

    Kryvich replied to Gary Mugford's topic in General Help

    First of all, you need to set your build configuration to Debug (Projects view | Build Configurations - double click Debug), and enable debugging options (menu Project | Options | Building | Delphi Compiler | Compiling): Optimization: False Stack Frames: True Debugging: all settings to True Runtime errors: all 3 settings to True Perhaps after that this error will appear earlier than when you close the application. Usually you do not need to initialize arrays - they are initialized with zeros automatically. How the arDeptsTotal array is declared? Is it 0-based or 1-based? Based on the code snippets you provided, the TList<TYourData> or TDictionary<string, TYourData> class might be more appropriate for you. But the good old array should works too.

    @Lars Fosdal RTTI can be selectively enabled for the classes that really need it.
  5. Kryvich
    Is it affect programs, written in Unicode enabled Delphi versions (Delphi 2009 and above)?
  6. Kryvich
    @David Heffernan How you think: is RTTI information concentrated in one place of an executable file, or scattered around it? Open any EXE file and find the answer. I would prefer that the RTTI information be in a separate segment (resource) of the EXE file, and preferably in a separate file. But you are right about performance: it is better to test, and then draw conclusions.
  7. Kryvich
    @stijnsanders I do not know such special settings. But you can use conditional compiler directives to leave RTTI for the Debug build: {$IFDEF RELEASE} {$WEAKLINKRTTI ON} {$RTTI EXPLICIT METHODS([]) PROPERTIES([]) FIELDS([])} {$ENDIF}

    @Bill Meyer That's the whole point: if Embarcadero can get the IDE to work on a such project, then CodeInsight will work flawlessly on projects with a well-designed architecture.

    Speed up reading multiple text files

    Kryvich replied to dummzeuch's topic in RTL and Delphi Object Pascal

    A memory table with indexing and filtering (Filter := "like 'bl*'") would help. If you haven't TkbmMemTable, there is TFDMemTable and TClientDataSet even in the Community Edition. Use BeginBatch, EndBatch to speed up the loading. Of course, you can write a low level code and try to squeeze the maximum speed, as advised above.

    MvmStartKit now supports 10.3 Rio

    Kryvich replied to Markus Kinzler's topic in Delphi Third-Party

    I tried MvvmStarterKit\Demo\VCL\MVVMDemo.dproj in Delphi 10.3. TYPE_KIND_TO_VALUE_TYPE should be appended with TgoValueType.Unsupported); // tkMRecord Demo program has memory leaks. The latest commit to https://github.com/DelphiPraxis/MvvmStarterKit dated October, 9. I suppose you forgot to push your Delphi 10.3 update to GitHub.

    A demo program that demonstrates the bug would help the community to help you.

    mORMot running on Delphi 10.3 Rio

    Kryvich replied to Arnaud Bouchez's topic in Delphi Third-Party

    So now (among other) we have FireDAC - a DAC for Delphi packed with advanced features, and the lightning fast Zeos - a free and open source lib. Both libraries can work in conjunction with mORMot. Having a choice is always good.
  13. Kryvich
    It takes time to update and test all components in Delphi 10.3. In GetIt in 10.2, I see 202 packages right now, and in 10.3 - 55 packages (at the start it was 34).

    Speed up reading multiple text files

    Kryvich replied to dummzeuch's topic in RTL and Delphi Object Pascal

    Alternatively you can try a memory table and compare it with TStringList. I recommend TkbmMemTable.

    MvmStartKit now supports 10.3 Rio

    Kryvich replied to Markus Kinzler's topic in Delphi Third-Party

    What is the difference between this kit and https://github.com/grijjy/MvvmStarterKit, in short?

    mORMot running on Delphi 10.3 Rio

    Kryvich replied to Arnaud Bouchez's topic in Delphi Third-Party

    The Zeos test results are astounding. What about the capabilities of this library? Does it support the on-demand rows fetching, rows pagination, delayed fetching (to postpone a BLOB and nested datasets loading)? FireDAC can do it: http://docwiki.embarcadero.com/RADStudio/Tokyo/en/Fetching_Rows_(FireDAC)
  17. Kryvich
    Very good library to test the CodeInsight and ErrorInsight features.

    Rio has a broken REST Library

    Kryvich replied to Jacek Laskowski's topic in RTL and Delphi Object Pascal

    As I understand WinHttpQueryHeaders should return an Unicode string, so LSize should be even. But we can foresee any variant, allocating enough space for the result string: SetLength(Result, (LSize+1) div SizeOf(Char));

    Rio has a broken REST Library

    Kryvich replied to Jacek Laskowski's topic in RTL and Delphi Object Pascal

    Before the second call of WinHttpQueryHeaders there is a check: if GetLastError <> ERROR_INSUFFICIENT_BUFFER then raise ENetHTTPException.CreateResFmt(...); It means that the call of function WinHttpQueryHeaders occurs only if GetLastError = ERROR_INSUFFICIENT_BUFFER. According to the API: If the function fails and ERROR_INSUFFICIENT_BUFFER is returned, lpdwBufferLengthspecifies the number of bytes that the application must allocate to receive the string.

    GetIt pkg mgr problems

    Kryvich replied to David Schwartz's topic in Delphi IDE and APIs

    @FredS No, it din't work for me. Can you find CodeSiteExpressPkg260.bpl in "c:\Program Files (x86)\Raize\CS5\Bin" ? Update: I found this file here: "c:\Program Files (x86)\Raize\CS5\Deploy\Win32\", copied it to "c:\Program Files (x86)\Raize\CS5\Bin" and now CodeSite works! https://quality.embarcadero.com/browse/RSP-21763

    I used the Migration Tool to move my syntax highlighting from 10.2.3 to 10.3.

    Rio has a broken REST Library

    Kryvich replied to Jacek Laskowski's topic in RTL and Delphi Object Pascal

    Weird. Waiting for your findings. The good thing is that CE comes with REST sources, so a competent enthusiast can help find a bug in the library.

    mORMot running on Delphi 10.3 Rio

    Kryvich replied to Arnaud Bouchez's topic in Delphi Third-Party

    So MySQL database + FireDAC- mORMot-Windows service could be compiled and run even with Community Edition, if the database and the service are located on the same machine.

    Android Z-Order, Native Controls, and 10.3 Rio

    Kryvich replied to Mohammed Nasman's topic in Cross-platform

    The main goal in 10.3 was to introduce Z-Order. So we can now place controls over video as example. Broader support of native controls planned for the first half of 2019, for 10.3.x updates. https://community.embarcadero.com/article/news/16638-rad-studio-august-2018-roadmap

    Update: CodeSite Express 5.3.3 appeared in GetIt in Delphi 10.3. Update2: Oops: Can not find CodeSiteExpressPkg260.bpl. Forgot to include in the installation?
