Circular console.log() output

[espruino-discuss]

Hi All,

When printing "this" with the console.log(function), the WebIDE freezes and the espruino has to be restarted. This is due to circular output. Example showing this:

function foo() {
  this.bar = new Bar(this);
  console.log(this);
}

function Bar( fooThis ) {
   this.fooThis = fooThis; 
}

var f = new foo();

Could this be detected in order to easily read out the this and stop WebIDE from freezing?

Thanks!

Alex

You're not having a good day for finding issues with Espruino!

It's implemented in the trace command and I was sure it was in the JSON output - I know JSON got re-done some time ago, so maybe support got removed at that point. It'll be fixed in 1v64

One could argue I'm having a very good day when it comes to bug hunting :). Main reason probably is that I develop for pcs, and then port to espruino, which is what I did today (hence the silence ;)).

Thanks again for the quick reply :) and keep up the great work!

If you wait an hour and then go to http://www.espruino.com/binaries/git/commits/c9bef247f458aff15aa8c20f98d2fccda4b63620 the automatic build should have made an Espruino image. It'll have this fixed, String.indexOf fixed, and String.slice added.

Hi Gordon,

Thank you very much! I'm out of the office at the moment (done for the day:)) so I'll check the link tomorrow!

It's great to see espruino getting better and better with every forum post!

No problem! Thanks for reporting the bugs with an easy way to reproduce them - it makes my life so much easier!

Hi Gordon,

I tried the build above but the red and blue led were glowing weakly afterwards, and I could not connect to the board anymore.

I'll stick with 1.63 until 1.64 is released.

Regards,

Alex

Strange. Not sure what happened, but I just tried that link and it works fine. You need to click on it, then right click on espruino_1v64_espruino_1r3.bin on that page, copy the link and paste it into the 'Advanced Firmware Flash' box.

Hi Gordon,

Ah I see, I just copied the entire link, my bad.

So... you put the link he posted into advanced firmware update...
But it was pointed at a directory instead of the firmware image.
Yet it flashed something... Did it flash the directory listing as if it were a firmware?

It might, it said it succeeded the flashing... I downloaded the bin file to browse to it but then it said URL so I figured, must look for the right one automatically from a default layout or whatever.

Interesting - there should probably be a check in for that. There's no CRC in the binary so it's hard to tell. It could just do a sanity check on the file size I guess.
