A new time traceable flag was added to pmc agent to store the current
time traceable status.
This flag replaces the utc_offset_traceable flag in the HA clock
selection algorithm and status command.
Test plan: HA clock selection algorithm
PASS: Verify the clock source which time isn't traceable is discarded
by the algorithm if ha_gm_timeTraceable is enabled.
PASS: Verify the clock source which time is traceable isn't discarded
by the algorithm if ha_gm_timeTraceable is enabled.
Regression: status command
PASS: Verify the response of status command shows the correct GM time
traceable.
The 'valid sources' command is used to get a list of interfaces which
the clock is matching the requirements. The response contains a space
separated list of interfaces, or "None" when not a single clock is
matching all the requirements.
Test plan: valid sources command
PASS: Verify that a space separated list of interface is returned when
one or more clocks match the requirements.
PASS: Verify that the string "None" is returned when not a single clock
match the requirements.
Now the GM time traceable check is enabled by default as it is an
important check for both T-GM and T-BC scenarios.
The GM time traceable check is controlled in configuration by using
the ha_gm_timeTraceable setting, and it can be disabled using the
value 0 (ha_gm_timeTraceable 0).
Test plan: default value
PASS Verify the check is performed by default.
PASS Verify the user can disable the check by configuration.
Bonus:
Fixed the behavior when none clock is matching the requirements and the
active clock source is disabled using the 'disable source <interface>'
command. The interface is must be disabled and a new clock source is
selected.
Test plan: none clock is matching the requirements
PASS: Verify that the active source can be disabled and a new one is
selected.
PASS: Verify that an attempt to disable the last active interface
fails and an appopriated message is given as response.
PASS: Verify that the interface with higher priority is selected after
re-enabling it.
PASS: Verify the active clock source doesn't change if another
interface is disabled.
PASS: Verify the active clock source doesn't change if another
interface is re-enabled.
