Bunyan v0.16.8 Release Notes

    • Guards on -c CONDITION usage to attempt to be more user friendly. Bogus JS code will result in this:

      $ bunyan portal.log -c 'this.req.username==boo@foo'
bunyan: error: illegal CONDITION code: SyntaxError: Unexpected token ILLEGAL
  CONDITION script:
    Object.prototype.TRACE = 10;
    Object.prototype.DEBUG = 20;
    Object.prototype.INFO = 30;
    Object.prototype.WARN = 40;
    Object.prototype.ERROR = 50;
    Object.prototype.FATAL = 60;
    this.req.username==boo@foo
  Error:
    SyntaxError: Unexpected token ILLEGAL

        at Function.Script.createScript (vm.js:48:10)

        at Function.Module._load (module.js:312:12)
        at Module.runMain (module.js:492:10)

    And all CONDITION scripts will be run against a minimal valid Bunyan log record to ensure they properly guard against undefined values (at least as much as can reasonably be checked). For example:

        $ bunyan portal.log -c 'this.req.username=="bob"'
    bunyan: error: CONDITION code cannot safely filter a minimal Bunyan log record
      CONDITION script:
        Object.prototype.TRACE = 10;
        Object.prototype.DEBUG = 20;
        Object.prototype.INFO = 30;
        Object.prototype.WARN = 40;
        Object.prototype.ERROR = 50;
        Object.prototype.FATAL = 60;
        this.req.username=="bob"
      Minimal Bunyan log record:
        {
          "v": 0,
          "level": 30,
          "name": "name",
          "hostname": "hostname",
          "pid": 123,
          "time": 1355514346206,
          "msg": "msg"
        }
      Filter error:
        TypeError: Cannot read property 'username' of undefined

            at Function.Module._load (module.js:312:12)
            at Module.runMain (module.js:492:10)

    A proper way to do that condition would be:

        $ bunyan portal.log -c 'this.req && this.req.username=="bob"'
