Probably not. When you add commits to the same branch, the commits are added to the PR. If you want to have separate PRs you need different branches for each change. Anyway your changes have been merged and you are listed as a contributor.

@dummzeuch I think handling connections sequentially should be quite easy, without resorting to multiple threads. Once one is closed you wait for the next one. Please bear in mind, that there are limitations when using libssh2 from multiple threads: Points 1 and 3 are the same, since the crypto functions are initialized by libssh2_init. Ssh_pascal handles this in a thread safe manner. The second point, I think means that you either have a session per thread or you protect with a lock, access to the same session and its channels,

A Pull Request implementing an alternative design that resolves this issue would be much appreciated.

The code in SshTunnel.pas is based on this libssh2 example. Maybe I missed something, in converting it to Delphi. It would be nice to fix it.

@dummzeuch I have pushed a couple of fixes to SshTunnel.pas (issues found by Copilot!). Could you please check whether they make a difference? One of them might: SocketOption := 1; // Initialize SocketOption

LIBSUFFIX AUTO has been a much requested feature for ages. The Delphi 10.4.1 announcement said: Sounded interesting so I decided to try that. I first searched the documentation and found the following: So I added {$LIBSUFFIX AUTO} to a package of mine say xyz.dpk and the bpl file generated was indeed xyz270.bpl. However I got an error message saying: This much for "full support" for this feature. Am I missing something??

There are about 75 highlighters and It is not too difficult to add new ones. You can start with a highlighter for a language that is quite similar and adapt it, e.g. change the keywords. There is also SynGen that helps you create a highlighter from scratch. You can request a highlighter and someone may have or contribute a new one. Regarding Powershell have a look at this discussion. It contains an extended General highlighter that can be adapted to practically any language. PSPad uses that unit to support syntax highlighting for 180 programming languages.

I have no idea what you are trying to accomplish, but for instance you can put the PythonModule in a data module. Instead of using AddDelphiMethod directly. you could add an Event to the PythonModules Event's collection. Events are converted to python functions, which delegate the execution to a Delphi event handler. Then, every time the form is created, it could assign a handler to the event's OnExecute property.

You should not free modules that have been initialized and loaded into python while the python engine is active. python has references to procedures of the module and this may lead to crashing python. You can destroy modules after python has finailized.

Works here with the same version. Are you using the latest sources now from the master branch.

Flow control symbols have also been added: Technical details.

Structural highlighting has also been added. Technical details.

In the demo project modify the CreateEngine function as follows: procedure TService1.CreatePyEngine; begin PythonEngine := TPythonEngine.Create(nil); PythonEngine.Name := 'PythonEngine'; PythonEngine.DLLName := 'python313.dll'; PythonEngine.DllPath := 'c:\python\python313\'; PythonEngine.PythonHome := PythonEngine.DLLPath; PythonEngine.VenvPythonExe := PythonEngine.DLLPath + 'python.exe'; // may be needed PythonEngine.RegVersion := '3.13'; PythonEngine.UseLastKnownVersion := False; PythonEngine.FatalAbort := False; PythonEngine.FatalMsgDlg := False; PythonEngine.LoadDll; TPythonThread.Py_Begin_Allow_Threads; end; I think this should set the python path correctly and avoid import errors.

What I think is best: - Create the pythonEngine (or load the python dll) on Start - Destroy the pythonEngine (or unload the python dll) on Stop - Follow these guideliines to execute python code in threads. Please see the attached project for an example that does that. Sample log output after starting and stopping the engine: Logs From Background Thread: 24/10/2024 14:49:18 Python eval = 4 Logs From Background Thread: 24/10/2024 14:49:19 Python eval = 4 Logs From Background Thread: 24/10/2024 14:49:20 Python eval = 4 Logs From Background Thread: 24/10/2024 14:49:21 Python eval = 4 Service.zip

I very much like the "Filter Explicit properties" expert. However, in recent versions of Delphi (not sure when it started), the IDE inserts annoying DesignSize properties that "pollute" the Dfm and the revision history. It would be really nice if the expert was renamed "Filter DFM properties" and included the option of removing these DesignSize properties.

The understatement of the year.

Delphi 12.2 is now available for download from https://my.embarcadero.com/.

When you run as a service the registry information is not available. You need to do something like: procedure TService1.CreatePyEngine; begin PythonEngine := TPythonEngine.Create(nil); PythonEngine.Name := 'PythonEngine'; PythonEngine.DLLName := 'python313.dll'; PythonEngine.DllPath := 'c:\pathtoyourpythonhome\'; PythonEngine.RegVersion := '3.13'; PythonEngine.UseLastKnownVersion := False; PythonEngine.FatalAbort := False; PythonEngine.FatalMsgDlg := False; PythonEngine.LoadDll; end; I have tested and it works.

Do you have any code you can share?

I am also sceptical. However, I see that in one of the most starred Github Delphi repos, danieleteti/delphimvcframework: DMVCFramework (for short) is a popular and powerful framework for WEB API in Delphi. Supports RESTful and JSON-RPC WEB APIs development., the IDE expert project generator, includes MSHeap by default. @Daniele TetiCould you please enlighten us as to what led you to this choice? By the way the RTL can be configured to use MSHeap, if compiled with the SIMPLEHEAP conditional define. The downside is that ReportMemoryLeaksOnShutdown is not available with MSHeap.

This is the unit @Stefan Glienke was referring to. 100 lines and it uses no other unit!

Set UseWindowConsole to True and in the FormCreate add: ShowWindow(GetConsoleWindow, SW_HIDE);

It is a bit tricky to run multiprocessing from P4D. For instance with Demo01: - Set VenvPythonExe to the appropriate python.exe path e.g. 'c:\python\python313\python.exe' - If you are printing from the processes and you want to see the output set UseWindowsConsole to True. In your script there is no printing from the processes. - Add to the above script as first statement: __file__ = file_path - Save your script to that filepath - Run the demo and exec your script.

This is just to say that pyscripter/Ssh-Pascal: Delphi ssh library wrapping libssh2 (github.com) includes binaries that do not require OpenSSL, but use Windows CNG instead. It also includes scripts that make it very easy to update the binaries.
