gnmic 0.38.2 regression test failure #494

Open chenrui333 opened 1 month ago

chenrui333 commented 1 month ago

While upgrading gnmic to do 0.38.2, seeing some regression test failure as below:

$ /opt/homebrew/Cellar/gnmic/0.38.2/bin/gnmic -u gnmi -p dummy --skip-verify --timeout 1s -a 127.0.0.1:0 capabilities
target "127.0.0.1:0", capabilities request failed: "127.0.0.1:0" CapabilitiesRequest failed: rpc error: code = Unavailable desc = connection error: desc = "transport: Error while dialing: dial tcp 127.0.0.1:0: connect: can't assign requested address"
Error: one or more requests failed

only pointer? Thanks!

relates to https://github.com/Homebrew/homebrew-core/pull/178522

I'm not sure this is a regression, in earlier versions it kept retrying and eventually timed out. With the new version it just fails fast. Running a capabilities request is probably not the way to test that the installation succeeded. I think running gnmic version is good enough.

do you have references for that? I just looked at the 0.38.0 and 0.38.1 builds, seems pretty clean to me.

you see it if you add --debug | -d to the command:
