[Bug]: VSCode gives error when formatting

[simonjwright]

Environment

• OS and Version: macOS Sequoia 15.0.1
• IDE Version: 1.94.2
• Ada & SPARK Extension Version: ? latest, I think I got it to update

Bug Summary and Reproducer

Bug Summary:

Error - 21:13:44] Request textDocument/formatting failed.
  Message: GNATformat failed to format source
  Code: -32603 ```

Steps to reproduce: 

1. Make a project using the source in [formatting_control.zip](https://github.com/user-attachments/files/17497887/formatting_control.zip), cf #1217
1. Select _Format Document_ from the right button menu.

Expected behavior:
Code formatted (I was hoping to compare the result with #1217).

re: exception traces & macOS:

Compiling with `-g` and `-bargs -E`, `Ada.Exceptions.Exception_Information` gives a much more useful trace. The test program does a recursive call, counting down, and raises an exception on reaching a limit:

$ ./raiser

Hello @simonjwright. Thanks for reporting this.

I was not able to reproduce on Linux. I suspect that this will be specific to the aarch64 ALS build. I'll try to reproduce on a Mac.

I have a couple questions though.

Compiling with -g and -bargs -E, Ada.Exceptions.Exception_Information gives a much more useful trace. The test program does a recursive call, counting down, and raises an exception on reaching a limit

What exactly was compiled here? ALS?

$ ./raiser

Can you elaborate on what raiser is?

[simonjwright]

Sorry to be unclear.

I don’t know how the stack dump in my bug report was produced, but - and I assume here it’s from a caught exception? - if you compile with -g (I assume you do, since the download includes ada_language_server.dSYM) and bind with -Es, you could use instead Ada.Exceptions.Exception_Message, which produces

• on macOS, a dump like this

  caught raised CONSTRAINT_ERROR : a message
  Load address: 0x104604000
  Call stack traceback locations:
  0x104608a7c 0x104608adc 0x104606460 0x104606488 0x104606488 0x104606488 0x104606488 0x104606488 0x1046064cc 0x104606d78
  

  where you give the Load Address to atos’s -l switch.
• on other OSs (well, at least Linux?) you should get a nicely symbolicated stack dump.

This is raiser's GPR

project Raiser is

   for Main use ("raiser.adb");

   package Builder is
      for Default_Switches ("ada") use ("-g");
   end Builder;

   package Binder is
      for default_switches ("ada") use ("-Es");
   end Binder;

end Raiser;

This is the source

with Ada.Exceptions;
with Ada.Text_IO;
procedure Raiser is
   procedure Inner(N: Natural) is
   begin
      if N <= 5 then
         raise Constraint_Error with "a message";
      end if;
      Inner (N - 1);
   end Inner;
begin
   Inner(10);
exception
   when E : others =>
      Ada.Text_IO.Put_Line
        ("caught " & Ada.Exceptions.Exception_Information (E));
end Raiser;

and this is the execution and stack dump processing

$ ./raiser
caught raised CONSTRAINT_ERROR : a message

Call stack traceback locations:

I don't know if this is at all related, but note that Mac OS's ARM64 calling convention is different from ARM64's official AAPCS64. I've worked with C-FFI for ARM64 on other languages, so I just want to point this out:

• AAPCS64
• MacOS

I see a lot of _ALS.PROJECT_ No alr in the PATH logs here: it seems that you are trying to load a project based on Alire, without having alr (the Alire executable) in your PATH. Could you try again after making sure alr is in your PATH?

Note that in parallel we will try to make GNATformat working on Ada files that do not belong to the loaded project, which would solve these issues in the long-term.

@rongcuid Note that I can reproduce on my side on Mac OS aarch64. We'll investigate.

I don't know why this is the case. alr is in my path in my terminal, but I think vscode doesn't pick it up.

Do you launch VS Code from your terminal, or outside of it? If you launch it outside of your terminal, you might want to have a look at this

Ok. I didn't know vscode can do that now. It does remove the error about alr

Great! We'll investigate the erroneous memory access on our side, keeping you posted.

@simonjwright I confirm that it's a aarch64 Mac OS issue: I can't reproduce with the extension built for x86-64 Mac OS.

I think you have worked on the aarch64 port for Mac OS right? Unfortunately at AdaCore we don't officially support this platform, so it will be hard for us to fix that issue, which looks like a pure compiler issue (the same code runs fine on Mac OS x86-64, Linux platforms and Windows).

Would you be able to investigate on your side? That would greatly help us and the Ada/Mac OS community. If not we'll see internally how we can proceed.

@AnthonyLeonardoGracio, I will certainly have a go. I’ll need to rebuild the compiler first (so I can decode those tracebacks, see GCC PR 117358). Would the GCC 14.2 compiler be an appropriate base?

I've built ALS (25.0.0) with my fixed compiler, and it's working, but how do I get VSCode to use it?

GNATFormat 25.0.0 works fine with my test code, see above.

VSCode is OK so long as I configure not to use gnatformat (i.e., use gnatpp).

I've managed to start ALS with --config /Users/simon/tmp/gf.json, which contains

{
    "ada.useGnatformat": true
}

but it seems to have no effect: when I formatted the file, ada.text_io was updated to Ada.Text_IO, and I don't think that's something that GNATformat does?

I tried replacing 'true' with 'maybe', and ALS refused to start up, so it's getting read. I tried "ada.useGnatformatX": true, with no observable effect.
