In theory what you said is correct, this is experimental API and anything can happen to it, this is the contract. And when we need to change an experimental API, the users will be affected, there is no escape from it. But for this case limitation is more mechanical I believe, because API is not changing at all, and it is becoming mature. So we are breaking the user application because the experimental API they are using becoming mature without any change. This looks annoying from the user perspective, and if we can prevent this break, I am for preventing it. > > > 29/01/2020 17:43, Ferruh Yigit: >> Duplicated the existing symbol and versioned one as experimental and >> other as stable. > [..] >> --- a/lib/librte_meter/rte_meter_version.map >> +++ b/lib/librte_meter/rte_meter_version.map >> @@ -20,4 +20,12 @@ DPDK_20.0.1 { >> rte_meter_trtcm_rfc4115_color_blind_check; >> rte_meter_trtcm_rfc4115_config; >> rte_meter_trtcm_rfc4115_profile_config; >> + >> } DPDK_20.0; >> + >> +EXPERIMENTAL { >> + global: >> + >> + rte_meter_trtcm_rfc4115_config; >> + rte_meter_trtcm_rfc4115_profile_config; >> +}; > > > >
