Bug: Slice is initialised with nil field values
swdee opened this issue · comments
Concerning the following line of code the initialisation of the slice opentracingFields
creates a slice of the size of the number of fields plus one presumable for the log string.
Line 141 in 6415450
However the method the real log fields are added to opentracingFields
is done with an append
function which causes these additional fields to be added after the nil fields initialized by make
. As a result nil/empty fields are passed to span.LogFields()
which causes empty log lines to be displayed in the WebUI of Jaeger.
To stop these empty fields being passed the opentracingFields
slice should be initialized as zero size, eg: Line 141 above should be;
opentracingFields := make([]opentracinglog.Field, 0)
Thanks for reporting, I confirmed this after a quick test. I will issue a PR for this.
