The decoder does not recognize the stack trace after copy/pasting to the terminal

Open dankeboy36 opened this issue 1 year ago • 9 comments

I have a similar issue. No matter what I copy/paste, it does not recognize the stack trace. It > would be nice if the extension could output some progress, like

successfully detected the cut marker start
successfully detected the cut marker end
successfully detected the exception context
successfully detected the stack trace marker start
successfully detected the stack trace marker end
[...]

or, in an error case

missing the cut marker start
missing the cut marker end
missing the stack trace marker start
missing the stack trace marker end
[...]

In my case, I think the bug is in Arduino IDE, because it only copies what is currently visible on > the screen, and not what actually has been selected [[probably this bug]](https://github.com/arduino> /arduino-ide/issues/1081). That's a pity. My traceback is several dozens of lines long.

Also,

--------------- CUT HERE FOR EXCEPTION DECODER ---------------

is not very helpful, because I don't know whether this is the start or the end of the cut.>

Thanks for using the extension.

@WelliSolutions, please copy/paste the content instead of trying to guess which Arduino IDE bug truncates the monitor content. Otherwise, it's impossible to give support.

The board's stack trace output produces this; how can the decoder extension change your board's output?

Well, I tried to, but it is not possible ...

... because of that Arduino IDE bug.

I didn't know that.

I understand your frustration, but you should copy/paste the content here to the GitHub issue as a code block. Otherwise, I cannot help resolving it. I hope this helps

I ended up here after a Google search, having discovered the same problem and can propose an (imperfect) solution.

As hinted in the first post, this is not a bug in the exception decoder, but in the Arduino IDE. The problem is that it is not possible to highlight and copy the entire stack trace to the clipboard, because when you Ctrl+C from the serial monitor, the only content copied is that currently visible in the Serial Monitor pane. It took me some time to discover this, but it's very easy to verify by simply attempting to paste the stack trace into, say, Notepad instead. You'll see that you only get a partial result, which is why the exception decoder therefore doesn't work.

The workaround I've used is to enlarge the Serial Monitor pane as large as possible, and then reduce the text size (Ctrl -) until the entire stack trace can be viewed at once. Then, it can be highlighted, copied, and pasted.

My stack trace is about 6x as long. It won't fit into the Serial Monitor, even on a 4K screen.

Oh, I agree, it's far from a perfect solution. But it's an issue for the Arduino IDE, not the ESP Exception Decoder.

It won't fit into the Serial Monitor

You can get a bit more vertical height to fit the stack trace by moving Serial Monitor to the right hand side panel of the Arduino IDE window:

  1. Press the Ctrl+Shift+P keyboard shortcut (Command+Shift+P for macOS users) to open the "Command Palette". A menu will appear on the editor toolbar: Command Palette
  2. Select the "Preferences: Open Settings (UI)" command from the menu. ⓘ You can scroll down through the list of commands to find it or type the name in the field. A "Preferences" tab will open in the Arduino IDE main panel.
  3. Type arduino.monitor.dockPanel in the "Search Settings" field of the "Preferences" tab.
  4. Select "right" from the menu under the "Arduino › Monitor: Dock Panel" setting.
  5. Close the Preferences tab by clicking its X icon.

If that still isn't enough, you can use a standalone serial terminal instead of Serial Monitor as a workaround for this bug in Serial Monitor. I can recommend the open source PuTTY:

https://www.chiark.greenend.org.uk/~sgtatham/putty/

When using an external terminal, make sure to close the serial port in the terminal before uploading a sketch or using Serial Monitor. The reason is that only one application can have the port open at a time so the external terminal would block Arduino IDE from using the port. Serial Monitor is smart enough to automatically juggle the control over the port during an upload so we don't have to do this manually when using Serial Monitor.

it's an issue for the Arduino IDE

It is being tracked here: https://github.com/arduino/arduino-ide/issues/1081

I have a similar problem but this has nothing to do with the copy/paste. The decoder reports "Could not recognize stack trace/backtrace" after pasting the entire dump from the serial stack trace.

Board is ESP32-C3 (XIAO_ESP32C3). I also tried the Ardu Uno Rev 4 (that's also ESP32 based) but that comes back with a "Unsupported board: 'arduino:renesas_uno:unor4wifi'" error. 2 Conclusions: 1) the C3 seems supported (but does not work); 2) the Uno R4 should also be added since that would be the same core.

For pasting the stack I tried a number of things, paste only the stack trace without the registry dump, paste without the top error line, paste without the ELF SHA line and more, none of those worked.

For repro here's the code:

void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
  Serial.println("SETUP");
}

class a
{
public:
  int a = 323;
  int geta() {return a;}
};

void loop() {
  // put your main code here, to run repeatedly:
  Serial.println("LOOP");
  delay(2000);
  a* _a = 0;
  //a* _a = new a();
  Serial.println(_a->geta());
}

stack trace:
