On Delphi 10.4.1 the MMX Code Explorer is mostly dead/inactive when running Delphi debugger

[panie 2]

MMX Code Explorer: Version 15.0.20.2385

Delphi IDE: Embarcadero Delphi  Version 10.4.1 / 27.0.38860.1461
Operating System: Windows 7 / Windows 8.1 / Windows 10

Severity: MAJOR

 

When running a debug session in Delphi 10.4.1, most of the MMX Code Explorer functionality is disabled/inactive.

 

o Start Delphi and create a small Windows VCL Application.

o Put a Breakpoint in the application (in a OnClick function or something).

o Run the application in the Delphi IDE debugger by pressing the F9 key in the IDE.

o Try klick on MMX -> Code Explorer -> ModelMaker Code Explorer in the IDE menu.

o Nothing happens!

o Try klick on MMX -> Source Indexer -> Show Source Indexer in the IDE menu.

o Nothing happens!

 

Sees something has become broken. Most of the MMX functionality seems to be in a

disable/hide mode when running the application in debug mode.

[Uwe Raabe 2059]

Weird - I have never seen this. A quick test didn't show this either. I will try on a clean Delphi installation later.

 

Meanwhile, can you try with a clean Debug Layout by deleting the Debug Layout.dst from %APPDATA%\Embarcadero\BDS\21.0\ ?

[Matthias 7]

Can confirm it for Code Explorer (docked and undocked). Source Indexer will be displayed once,  afterwards it fails too. Debug Layout. has been deleted.before for testing again, same behavior.

[Uwe Raabe 2059]

As there must be a reason why it doesn't happen here: Any other non-standard plugins installed?

[panie 2]

1) I have deleted the Debug Layout.~dst and Debug Layout.dst file. No change. in that MMX still disabled/inactive.

 

2) I also removed all other IDE plugins except MMX Code Explorer. No change in that MMX still disabled/inactive.

 

3) It seems to have nothing with if I have Code Explorer and/or Source Indexer docked or as normal modal dialogs in the Delphi IDE.

 

Can it be something similar to what I had with GExperts 1.3.16 which krashed alot when running i Delhi 10.4.1? Luckily there where a fix in the form of a new DLL to use specifically for Delphi 10.4.1.

 

 

PS. On the issue of crashes, I receive crashes when searching using Source Indexer in MMX. Something is not quite up to speed with this Delphi together with MMX.

Do you get call stacks with the crashes? If so, I would provide a map file to get more information from it.

[panie 2]

I got this crash on m Windows 7 machine.

 

Seems CnPack has something to do with it. I have installed CnPack version 1.2.0.1013_Unstable installed. Maybe there is some unstable code that drags down MMX Code Explorer too.

I got the crash when I double clicked on a found code row in the Source Indexer docked window to go to the correct row in the source file.

[panie 2]

I have now removed CnPack and doing the same thing as before (just double clicked on a row in the Source Indexer docked window).

PS. Without the CnPack installed my feeling is that MMX got much more stable.

 

[panie 2]

Are there som switch I can turn on in the MMX Code Explorer so logging will occur. This so that I can help in the

search for why the MMX Code Explorer seems "dead" when I debug a Delphi program?

 

[FPiette 384]

Source indexer doesn't work here (not shown when asked). Never noticed it is when debug layout is active.

I have a basic setup with MMX being the only add-on.

 

[Uwe Raabe 2059]

I have uploaded a new version, which is identical to that I am working with in the moment. In addition I have attached a map file for the 10.4 instance of this MMX version. Place the map file next to the MMX_BDS21.dll. This will give some more verbose call stack for the MMX part.

 

The problem about empty floating windows is reported from others, too. Currently I have no idea what could be the cause, so we have to investigate further. Fortunately I can somehow force this problem to appear, when I create a layout where the MMX windows are undocked. Starting a debug session with closing those windows and opening them again after debugging actually shows these empty windows. At least that is a point where I can start.

 

Just checked, it works perfectly with 10.3.3 

MMX_BDS21.map

Edited October 9, 2020 by Uwe Raabe

[Uwe Raabe 2059]

A fixed version V15.0.27 is available.

[panie 2]

Does it work if I run the installer on top of the previous installed MMS ?

 

Before I have usually unstalled MMX followed by a fresh new installation. But then I have to configure the MMX again.

 

[Uwe Raabe 2059]

As long as you choose the same setup mode (for me only / for all users) as before there should be no problem. The setup will detect the previous installation and replace the files without manipulating your settings. If that isn't the case with your installation, please contact me so we can find the cause.

[panie 2]

I have no tried out the new version 15.0.27, and it's a BIG improvement !!

 

I have had a blank docked MMX Code Explorer window a few times, but it redraws itself if I switch back and forth among the other docked windows.

 

Now I can use the Source Indexer function without any crashing too.

Installed. Up to now source indexer works as expected. Thanks.

btw: I almost use only the source indexer.

[panie 2]

I'm running with the new version 15.0.27 with only MMX Code Explorer active. I have also copied in the MMX_BDS21.map file.

 

Got the following error when clicking on a row in the Source Indexer window.

PS. I have received a couple of error messages like the one above. Takes more trying (but not that much more) than in the old version.

 

PPS. On the issue of receiving blank docked MMX tool windows, I get the same blank windows fo GExperts too.

That callstack doesn't make any sense at all. Both mentions of MMX are from VirtualTrees. The corresponding line 10883 says 

    Canvas.FillRect(Rect(0, 0, Width, Height));

Even as weird for the other one. Line 5706 says

Result := Tree.GetDisplayRect(Node, Column, True, False);

Nothing looks like it may end up in a call stack as shown.

 

I can update to a newer VirtualTrees version and see if that helps.

 

BTW, the blank window issue is a 10.4.1 thing.

Fingers crossed.

 

Let me know if you have a test DLL file tha you want me to help with testing.

 

[Uwe Raabe 2059]

Wait a minute. The map file I attached before belongs to the previous version. Can you try again with the correct map file attached here, please?

 

I will see if I can include the map files in the setup.

There is a new version available where VirtualTrees is upgraded to a more recent version. There were a lot of things to adjust as MMX made some changes to VirtualTrees which had to be reworked a bit.

Wouldn't be interesting to update VirtualTrees source code at https://github.com/JAM-Software/Virtual-TreeView ?

I already thought of that, but most of the changes are needed to make the control compatible with the IDE styling. That is probably of less interest to the public. Nevertheless, I will see how this might be integrated with minimal footprint.

I'm sure everyone will love to have a styled VirtualTree!

 

[Uwe Raabe 2059]

The current VirtualTree already supports VCL styling. I am talking about IDE styling for IDE plugins, which is somewhat different to the normal VCL styling.

 

On the other hand I just noticed that the latest version still doesn't support per control styling. That would make a good kludge I could contribute.
