I'll look at it eventually [...] We formally reported the present problem (github #118) over a month ago and a possibly related one (now github #156) years ago. > Have you written any test code so far to isolate and attempt to > reproduce the problem outside of pmwebd? [...] The problem has already been reported outside pmwebd. I have no instrumentation ready to induce the failure(s) mechanically. If I did, the problem would be solved already. > doing that would be quite helpful & would form the basis of those QA > tests Mark mentioned. Mark was talking about QA for the cross-version compatibility checking. It was not this stuff, which I agree would be useful. > [...] As to the valgrind threading reports, same thing - we need to > see specific issues being resolved there and explain how, why, etc. I have tried to explain lock ordering bugs with various levels of specificity several times on the list. Would it help if I walk through some random individual bug with small steps? > They could well be simple things that are easily fixed (if PMAPI > threaded tools eventuate) or non-issues in practice - who knows? > Not us, not yet. I have reported & analyzed actual observed deadlocks on the list months ago. Deeming them non-issues would guarantee that PMAPI threaded tools disappear rather than eventuate. - FChE -=-=-=-=-=-=-=-=-=-=-=- pcp mailing list [email protected] https://groups.io/g/pcp/messages -=-=- Groups.io Links: You receive all messages sent to this group.
