Thank you for opening this issue, we will look into it.
Thanks for the feedback! We are routing this to the appropriate team for follow-up. cc @AzureAppServiceCLI, @antcp.
After spending a bit more time looking into this it's not just mysql. I'd used --help
as the debug case on the assumption that it'd be the simplest case, but different commands hang for a very similar timeframe in different places. For instance the az account get-access-token
command that originally sent me down this rabbit hole looks like this:
cli.knack.cli: Command arguments: ['account', 'get-access-token', '-o', 'json', '--resource', 'XXXX', '--debug']

In your first debug log (https://github.com/Azure/azure-cli/issues/29703#issue-2458681549), mysql
takes 5s to load:
$ az --help --debug 2>&1 | ts '%H:%M:%.S'
...
cli.azure.cli.core: mysql 5.062 15 53
However, on my machine, mysql
only takes 0.065s to load:
$ az --help --debug 2>&1 | ts '%H:%M:%.S'

In your second debug log (https://github.com/Azure/azure-cli/issues/29703#issuecomment-2278808124), you can see the command index takes effect, thus only profile
and resource
modules are loaded.
In my test, no pause is observed:

I would recommend testing it multiple times and see if you can have a steady repro. Also, please check if you have a high CPU usage.
Let's keep monitoring and see if other people are seeing the same issue.
I would recommend testing it multiple times and see if you can have a steady repro. Also, please check if you have a high CPU usage.
So I went and ran az --help
in a loop and collected timings. The timing is extremely consistent. Across 20 runs they took a mean of 5.47 seconds with a maximum deviation of 50ms in either direction. CPU was over 90% idle over the entire test with no run taking more than 240ms of CPU time.
Ok, so after some more digging around I managed to get a trace pointing the finger at socket.getfqdn()
. It seems that somewhere in the OS upgrade I did around the same time something changed with either /etc/hosts or the name returned by socket.gethostname()
, with the end result being that the call to socket.gethostbyaddr(name)
was hitting the DNS timeout (thus the tight timing distribution).
I'm still not sure why this was showing up as a delay/timeout when other codebases (nslookup, dig) would get an immediate NXDOMAIN when attempting the same query, or what exactly changed to make this suddenly show up now. That said it's easily solved with an /etc/hosts entry so I'm going to set it aside for now.
I'll go ahead and close this since it seems to be a mac/python issue rather than an azure-cli issue. Sorry for the false alarm.
Describe the bug
Many commands (az --version, az account get-access-token, etc.) suddenly seem to just pause for ~5 seconds before doing anything.
Related command
