Can't set bp on multiline expression

[roblourens]

• Have a simple script with a multiline expression like

const abc = 'abc';
let xyz = abc.trim()
    .trim();

console.log(xyz);

• Set a BP on the console.log line, launch
• Paused on the BP, try to set a BP on the let xyz line

• The debug adapter gets a setBreakpoints request to add the BP, then immediately another to remove it.

Works in 1.16

I cannot reproduce this both on my Mac and on my Win VM.

@weinand can you please try reproducing this

@roblourens what debug extension are you using, node2? In order to get more information about this it would be best if you place a breakpoint here and inspect why there is an extra call to setBreakpoints

[weinand]

I can repro with node.js 7.9 and 7.10 for both protocols.
I cannot repro with node.js 8.9 and 9.0 for both protocols.

[isidorn]

I can also repro but only for 7.9. Investigating...

Verifier: please verify in great detal how breakpoints get updated in the glyph margin when:

• a user edits the file
• adapter changes the location of the breakpoint
• brekapoints get added / removed while a debug session is active
