03/01/2017, 8:12 AMNot sure whose fault this one was. But need to make sure to commit the bumps to native_engine_version before merging. - r

03/01/2017, 5:46 PMah, it was a native_engine_version mismatch? - r

03/01/2017, 5:47 PMits too bad travis doesn’t have the notion of sq - f

03/01/2017, 7:11 PM@full-kilobyte-93429 whats that output from? - r

03/01/2017, 7:12 PMI think gperftools would work for cpu profiling too, but I can’t seem to figure out how to correlate the function addresses it reports to actual functions in the rust code - r
rough-minister-58256
03/01/2017, 7:12 PMlooks like whatever you’re using is at least symbolizing part of the rust stuff tho. - f

03/01/2017, 7:20 PMgperftools - r
rough-minister-58256
03/01/2017, 7:21 PMinteresting that its symbolizing for you - r
rough-minister-58256
03/01/2017, 7:22 PMwhats your pprof invocation look like? - f
full-kilobyte-93429
03/01/2017, 7:23 PMalso looked instruments and
, the former has similar symbol issues, the latter raised panic errorcpuprofiler - f

03/01/2017, 7:25 PMthats the perl pprof? - f
full-kilobyte-93429
03/01/2017, 7:26 PMfrom gperftools, yea perl - r

03/01/2017, 7:26 PMgoog rewrote pprof in go here: https://github.com/google/pprof - r
rough-minister-58256
03/01/2017, 7:26 PMmay try that too - r
rough-minister-58256
03/01/2017, 7:27 PMI think you can do ~go build <http://github.com/google/pprof|github.com/google/pprof> -o ~/bin/pprof - f
full-kilobyte-93429
03/01/2017, 7:28 PMok, will try, does that give you more symbols? - r
rough-minister-58256
03/01/2017, 7:28 PMive had mixed results between both tools 😕 - r
rough-minister-58256
03/01/2017, 7:28 PMbut its routines for enumerating symbols are likely diff, so may have more luck - f

03/01/2017, 7:28 PMare linux tools better? - r
rough-minister-58256
03/01/2017, 7:29 PMusing the same tools on linux - r
rough-minister-58256
03/01/2017, 7:29 PMfor cpu profiling, you might be able to useperf
