Thanks for the great solution, after a first review here is what I found:

It would not compile, ambiguous over load error.  I changed the if statement to be more generic than the {$IFNDEF RAD_XE3_UP}

  {$IF  CompilerVersion < 24.0} // System.Pos with offset starting from XE3
  function Pos(const SubStr, Str: string; Offset: Integer): Integer; overload;
  {$ENDIF}

I fails to print method name in 11.1, but works in 10.4 & 10.2.

I debugged it a little and the map file is loaded, but the lookup seems to fail in GetAddrInfo. line 322 fails the test :   if (laIdx = -1) and (paIdx = -1) then Exit(False);

Do you have any guess as to the difference in 11.1?

It is what you need, consider how you are building the package, specifically the run time and design time flags you are setting, use the above:

Test the mix of $DESIGNONLY and $RUNONLY that fits your usage.

From what I know, you add a second SDK in SDK manager, then right click on the platform select properties and choose which SDK it is using in Delphi:

This window controls what you compile with in Delphi.

During the boot camp, Holger Flick pointed out this tool to let you switch versions on the MAC, https://github.com/RobotsAndPencils/xcodes , I have not tried it myself.

He briefly gave an explanation about why they had to match but I can not quote it. It seems they must match to do the compile and PAServer only uses the active version of XCode / SDK on the MAC.

Hope it helps

in case someone is interested

I would be interested for sure, any approach to reading the map file is worth posting to save others time and learn the tricky aspects.

The Deputy 2.6 series separates features in to Process Manager and Instance Manager and integrates configuration options with the standard IDE options interface.

Deputy 2.6 is available in Getit or on Github with a GPL license or purchase a named user license for $9 USD.

If you use the plugin, please give it a star on Github. As always feedback is appreciated on GitHub, email or here in the thread.

Process manager now has:
- Ability to abort Process Manager
- Ability to force terminate managed process
- Settings moved to Options in the IDE
- Poll and loop settings exposed

Instance manager is a solution to this thread and several related defects in QP

I used this a few months ago, was simple enough for SQLite

https://github.com/davidlastrucci/Trysil

My Bad, DEB is Delphi Event Bus, from your thread you just call : https://github.com/spinettaro/delphi-event-bus

 GlobalEventBus.Post(lEsa, 'Processed');

On the form you can subscribe and handle the sync by choosing the thread mode:

    [Subscribe(TThreadMode.Main, 'HostUpdated')]
    procedure OnEventHostAdminUpdate(AEvent: IDEBEvent<TSERTCCollectionHostSSH>);

First note Dalija's response above about the TMemo.

Your memory leak will be solved by calling finalize on modDBFiredac before you call free.

If you are going to use python on a thread replace TPythonGUIInputOutput with TPythonInputOutput and consider using DEB to send messages to the main thread, it handles the sync.

Have you read the section

I skimmed it only and thought it relevant to the original question, at least in theory.

Every time I have tried to save time with this, I end up with the infamous dcu built with version x dcu error, along with all the random errors in the IDE with things out of sync.  I ended up purchasing the fastest clock CPU I could get and am happy enough. I just let it build the DCU's when necessary (TMS also does this so I figure if they did not come up with a more reliable solution, I would not either.)

I found this today and I think it is what you are trying to achieve or at least might help you in the right direction.

But it is not clear from your website or Github page exactly what I would need to download or purchase to get just this IDE functionality

I appreciate the feedback, I updated the Github site to make the license options more clear.

The purchase link here: https://swiftexpat.com/deputy.html is a license with support for $9 USD for a term of 1 year. (Currently the download and install of the licensed code is performed in Caddie, but you do not need to purchase a license. I re-use most of the IDE version logic built into Caddie to be able to register the expert in the IDE.)

Does this make it clear?

Since the OS is force closing your application, my mind goes to ALSR or DEP and the implementation on Server. Possibly the way the SSL is compiled in relation to these.

There is a lot of reading, but maybe you could just compile your exe with these options and see if it fixes before you spend too much time reading the detail.

OpenSSL DLLs, win32 or Win64, if I build it with YuOpenSSL which links the C code into the app, it does not fail.  

This makes me think the flags used in compile of SSL is where your problem really is.  Maybe dump those PE headers and see if you can spot the problem : https://github.com/changeofpace/PE-Header-Dump-Utilities

You can run/debug multiple executables in a project group at the same time

Wow, I learned something new. I verified with a VCL and FMX app at the same time, the debugger attaches to both.  Just curious, do you do this often and is it stable (as stable as the IDE ever is and not counting application crashes)  attached to 2 processes?

Here is my first round solution, see if it would work for you. https://github.com/SwiftExpat/Deputy

You can start multiple instance(s) of the IDE, that seems like a logical way to debug your applications. Instance 1 you would select phone 1 and Instance 2, select phone 2.

It can take hours for the task to complete.

I am more curious about the behavior of Android, does the OS ever kill your application? Or does it seem stable?

Process monitor from Sysinternals is your friend here. Trace the startup and see where the file is not found.

Python at the command prompt is built with vcruntime, and Delphi does not. Put a copy of msvcp140.dll and vcruntime140_1.dll in the directory that has your EXE and then see if works correctly.

If anyone is still interested, here is a prototype, would there be any other items to put on a wish list?

Original instance is on the left, Second instance is on the right with the notification and option to close either IDE or ignore.

It respects the -r option.

Code is here: https://github.com/SwiftExpat/Deputy/tree/SingleInstance

A long time ago I wrote one for files in the $(DELPHI)\Source directory:

Thank you for the example, I think this will keep me busy on my next plane ride.

Almost everything on the browse, library and search path could be read only for me.

But I need it for custom third-party classes.

Components or classes? Components will be TPersistent and they should be registered in the IDE, so more is possible with those.

The class tree will look something like this for TButton:

I need to get e.g. Vcl.StdCtrls.TButton from TButton. How can I do that?

You can get the defining class from the component, Marco's Object Debugger does it with the following lines using RTTI.

var
  ptd: PTypeData;
  
  //this starts at line 280 in ObjectDebuggerForm.pas
  
  // get a pointer to the TTypeData structure
  ptd := GetTypeData (pti);

  // access the TTypeInfo structure
  sList.Add ('Type Name: ' + string(pti.Name));
  sList.Add ('Type Kind: ' + GetEnumName (
    TypeInfo (TTypeKind),
    Integer (pti.Kind)));

  // access the TTypeData structure
  {omitted: the same information of pti^.Name...
  sList.Add ('ClassType: ' + ptd^.ClassType.ClassName);}
  sList.Add ('Size: ' + IntToStr (
    ptd.ClassType.InstanceSize) + ' bytes');
  sList.Add ('Defined in: ' + string(ptd.UnitName) + '.pas');

  // add the list of parent classes (if any)
  ParentClass := ptd.ClassType.ClassParent;
  if ParentClass <> nil then
  begin
    sList.Add ('');
    sList.Add ('=== Parent classes ===');
    while ParentClass <> nil do
    begin
      sList.Add (ParentClass.ClassName);
      ParentClass := ParentClass.ClassParent;
    end;
  end;

This is just a followup for reference to staying at the HTTP level for checking server file details.  It is related to this thread but applies more to large files or binaries.
I was exploring this and went a slightly different direction using another HTTP header, If-Modified-Since.

Working implementation can be found here, I am using in my Deputy expert update code.

https://github.com/SwiftExpat/Deputy/blob/main/Source/SE.UpdateManager.pas

Add your header, the supplied value had to be a valid date for my server was the only catch, so I defaulted it with a constant.

const
	dt_lastmod_default = 'Fri, 01 Apr 2010 23:15:56 GMT';
	hdr_ifmodmatch = 'If-Modified-Since';
...
  FHTTPRequest.CustomHeaders[hdr_ifmodmatch] := LastModified; // date must be a valid value;
  FHTTPRequest.Get(URL);
...

Handling the response is easy, just switch on the status code.

if AResponse.StatusCode = 200 then
  begin
    LastModified := AResponse.HeaderValue[hdr_lastmodified];
  end
else if AResponse.StatusCode = 304 then
  begin
    RefreshDts := now;
    LogMessage('File not modified Http result = ' + AResponse.StatusCode.ToString);
  end
else
    LogMessage('URL Cache Http result = ' + AResponse.StatusCode.ToString);
  

The Deputy 2.5 series contains enhancements based on user feedback and GitHub Issues . Many thanks to all of your suggestions.

• New functionality - the ability to close your application, which allows your application to correctly shutdown, display a memory leak report and capture the leak report for later review.
• Messages are now much cleaner so the build messages stay in focus.
• Deputy is available under an individual license for $9 USD.  Details on the product page

Sometimes the IDE won't close probably event user had select exit or click the windows close button, still we have to use task manager to force close it.

This could be implemented in an expert by displaying a screen on startup which allows you to terminate the old instance. Not technically a prevention of multiple instances, but cleaner than having to start task manager.
I can see this as a common frustration that can be solved, I add it to my list to explore as an enhancement.

I would probably never use this option as long as it doesn't take the IDE version and the given registry option (-r) into account

One more requirement check the username, I have a separate demo user account that I often switch to.

There are enough funds for my work there.

My laptop is similar age and memory, but Delphi runs good enough. Startup is about 10 seconds.

If it was my machine I would be starting with a clean OS install & clean Delphi.  These symptoms are going to take you longer to troubleshoot and keep you crying.
