1620796 - js-analyze.js produces nestingRange with -1 column index

Status: RESOLVED FIXED

(Webtools :: Searchfox, defect)

Description

[Kartikaya Gupta (email:[e-mail])]

I tried running a new mozilla-archived run with all the new ESRs. It crashed when trying to parse the nestingRange in this analysis line:

{"loc":"5:8-11","source":1,"syntax":"use,prop","pretty":"property url","sym":"#url","nestingRange":"5:14-7:-1"}

because the final column value is -1 which is not a u32 and so panics here.

The file that produced this analysis line is addon-sdk/source/test/fixtures.js in the esr31 branch. The source file looks like this:

exports.url = path =>
  module.uri.substr(0, module.uri.lastIndexOf("/") + 1) + "fixtures/" + path

Also as of this writing the AWS instance i-0d8836d412006b1af is stopped and holds the state necessary to reproduce the rust panic, see the last command in ~/index-log.
