Delphi 11.2 unofficial LSP patch

[Brandon Staggs 278]

Saw this blog post today:

 

https://www.ideasawakened.com/post/unofficial-delphi-lsp-fix-for-11-2-is-now-available

 

I grabbed the updated DLLs and LSP exe from the links and sure enough it seems to be working much better now. The files are dated Jan 10 so I suppose these are part of the current beta as well. No NDA issues here since Embarcadero posted the files right into the issue tracker and is asking for feedback in the RSP.

Although, take care, David Millington commented on that blog post warning it should not be used to build anything that will go out to a customer...

[Darian Miller 361]

It's definitely a beta quality update and not intended for widespread use, but the more feedback they get the better.   This has been such an annoying issue...

Did anyone try this for longer already? I'm a bit worried because of the "do not use in production" thing and I can not decide if it's only the mandatory warning or it indeed can mess something up badly.

[Brandon Staggs 278]

I've been using it since I posted the link. Seems to work fine and the IDE is back to working well enough that I forgot I had installed the patch! However I will be removing it before building any production code. I am using it temporarily as a way to increase my productivity to where it was before installing 11.2.

Does anybody know whether this patch also affects commandline builds?

For me it would be a huge inconvenience to be forced to uninstall the patch every time I want to do a production build. But having a better working less broken IDE is definitely desirable.

Why would LSPServer affect anything that dcc32/64 do?

As it replaces dcc32280.dll and dcc64280.dll, which are used by DelphiLSP, the command line compilers stay the same and are not be affected.

[Fr0sT.Brutal 900]

Then I can't get why this "do not use in production" warning. IDE has no relation to "production". Or they mean main dev environment?

[Lars Fosdal 1792]

Any company would add such a disclaimer when releasing unofficial "patches".

It means: If it didn't work, don't blame us.

For all I know about that patch it might replace a dll that the commandline compiler uses.

What they mean is "Don't use a patched IDE to produce anything (DLL, Exe, DCUs, BPLs whatever) that's going to be used in production".

And those command line compilers do not use the dccxxxx.dll files?

No. AFAIK it uses (besides some Windows core DLLs of course) only RLink32.dll and perhaps borlandmm.dll.

The patch replaces dlls. Since I do not know for sure who uses those DLLs, and they are saying not to use Delphi to build stuff for consumers with this patch installed, I'll be playing it safe. But if we can know for sure that those DLLs are only used by LSP, then I guess the warnings from Embarcadero are just overkill CYA.

FWIW, I have tried the unofficial LSP patches and I could no longer debug programs.   So I went back to the original dlls and debugging was available again.

All my breakpoints just become unavailable (like code never gets executed in that function), did you meet the same issue?

Yes.

[aehimself 396]

I can confirm. Rolling back the patch and my breakpoints are good as new on Win64 platform.

[KenR 29]

Debugging works fine for 32-bit but not 64-bit.

[aehimself 396]

I honestly can not understand this patch. After reverting back to the original files and reapplying it, breakpoints work fine on 64 bit as well, even in a new method of an unsaved unit...

Very strange. I take it that you just copied the contents of both zips to the bin folder!

My process:

- Install 11.2 and use it

- Rename 4 affected files to *.*.original

- Unzip both unofficial fixes to \bin folder

- Try to use it, breakpoints broken, so

- Rename patched files to *.*.patched, rename *.*.original to *.* and use it

- Since 32 bit is working and DelphiLSP.exe is a part of the 32 bit version, I decided to use 32 bit version only. Rename those files to .original, rename .patched to normal

- Breakpoints working, so I start to wonder and do the same with 64bit

- Confused as hell, as it's working...?!

 

[aehimself 396]

...and 64-bit breakpoints broke again today using the patch.

Important hint regarding LSP

 

Yesterday I noticed that with both Delphi 10.4 and Delphi 11, an invalid path reliably knocks out the LSP. (Yes, this is reported and goes its way).

 

This invalid path can be at least in the system PATH, the library path and unfortunately already simply the search path. You can easily test this yourself by entering a non-existent path there and restart Delphi. Important: If you correct it, you may have to restart Windows. For some reason it is not always enough to restart Delphi and the DelphiLSP.exe (even if the system PATH is not changed). I haven't looked into that yet and it doesn't always happen.
