Approach

What is the motivation for this PR?

test_config_reload is failing intermittently at:

Line 97. Even though wait parameter to reboot is being passed as 5, but if plt_reboot_dict is defined in the inventory, this wait time would be overwritten to value in plt_reboot_dict - Line 220
Line 108. After successful config reload, we are not checking for database service has started before executing config reload again. If database service has not started, we see the following exception:

"Traceback (most recent call last):File \"/usr/local/bin/config\", line 8, in <module>
    sys.exit(config())\n  File \"/usr/local/lib/python3.9/dist-packages/click/core.py\", line 764, in __call__
   return self.main(*args, **kwargs)\n  File \"/usr/local/lib/python3.9/dist-packages/click/core.py\", line 717, in main\n    rv = self.invoke(ctx)  File \"/usr/local/lib/python3.9/dist-packages/click/core.py\", line 1134, in invoke   Command.invoke(self, ctx) File \"/usr/local/lib/python3.9/dist-packages/click/core.py\", line 956, in invoke    return ctx.invoke(self.callback, **ctx.params)  File \"/usr/local/lib/python3.9/dist-packages/click/core.py\", line 555, in invoke    return callback(*args, **kwargs)  File \"/usr/local/lib/python3.9/dist-packages/click/decorators.py\", line 17, in new_func    return f(get_current_context(), *args, **kwargs)  File \"/usr/local/lib/python3.9/dist-packages/config/main.py\", line 1104, in config    ctx.obj = Db()  File \"/usr/local/lib/python3.9/dist-packages/utilities_common/db.py\", line 12, in __init__    self.cfgdb.connect()  File \"/usr/lib/python3/dist-packages/swsscommon/swsscommon.py\", line 1862, in connect    return _swsscommon.ConfigDBConnector_Native_connect(self, wait_for_init, retry_on)\nRuntimeError: Unable to connect to redis: Cannot assign requested address"

How did you do it?

-the wait time should only be changed to value defined in plt_reboot_dict only when its value is 0. Else should pick the value sent in the function call.
-Check if interfaces-config.service is exited successfully & database containers has started before doing config reload for the second time

How did you verify/test it?

Ran the test against T2 chassis multiple times

Any platform specific information?

Supported testbed topology if it's a new test case?

tests/common/reboot.py

-        if plt_reboot_ctrl:
-            wait = plt_reboot_ctrl['wait']
-            timeout = plt_reboot_ctrl['timeout']
+            if plt_reboot_ctrl:


why change indention here?

this is not a feasible fix, it'll only overwrite timeout if wait == 0, however, the intention for having plt_reboot_ctrl is to give privilege for some TBs(chassis) to predefine a new timeout/wait that has more tolerance.

I just checked the wait is only used

sonic-mgmt/tests/common/reboot.py

Line 238 in 34ce7e3

time.sleep(wait)

, which is time for dut to be stabilize, and 5 sec is not enough for chassis. why do we want to keep it as 5?

**the wait has kept for small duration intentionally to verifythe test -for reload configuration checks. The test is simulated to perform config reload before the dut is stablize and expect a check to the proper message.
***The plt_reboot_ctrl should only apply, if the (wait) time is not explicitly provided for a known objective

thanks @ansrajpu-git, please check my latest change, I have added a flag to control this, instead of overwriting both timeout and wait only if wait is 0.
please see if it works for you too?

wenyiz2021 · 2023-06-23T19:59:04Z

hi @ansrajpu-git, thanks for your fix.
I have added some additional change:

added a flag plt_reboot_ctrl_overwrite in reboot function to decide whether we want to overwrite wait and timeout. by default is to overwrite, in this test test_reload_configuration_checks we don't want to wait for that long, we want to catch transient error, so the flag is False.
changed to run on every sku with enum_rand_one_per_hwsku_hostname

I have confirmed this worked on Arista chassis, please also confirm if it works for your case
