Updating the bidirectional link quality requires a two-way exchange via MLE
Advertisements. In the worst case, this can take 2.5x the worst-case MLE
Advertisement period. This commit increases the delay after updating link
quality configurations.
This commit adds the following features:
- Example posix drivers to support virtual time simulation, allowing tests
to run faster than real time.
- A python-based simulation driver that coordinates the virtual time
simulations. Each alarm event and message transmission across all nodes
are scheduled in a single discrete time event queue. As a result, only
a single node is making forward progress at a time.
- Updated tests to utilize new virtual-time simulator, allowing them to run
faster than real time.
- To enable virtual time feature, define VIRTUAL_TIME=1 env var and set
CPPFLAGS=-DOPENTHREAD_POSIX_VIRTUAL_TIME=1.
This commit modifies the method assertSentToNode to confirm if the destination Mac address of
the message is the node's Mac address. Add method check_parent_request, check_parent_response,
check_child_id_request and check_child_id_request to command.py.
The unstable failing lies in when Leader has lower partition id and switches to better partition
formed by original routers. The default RouterSelectionJitter of Leader is 120s, however the
migration waiting time in script is 60s, thus there are chances that the ping happens when the
Leader just becomes router in the new partition but before link sychronization, causing the ping
packet dropped on ROUTER3.
Two options to resolve this: 1) increase the waiting time for migration to a value > 120s or
2) configure router selection jitter to a small value to relax the waiting time requirements.
Add a fuction in node.py node_cli.py to node's address.
Add a module command to verify commands.
Spinel-cli.py doesn't request address for dhcp prefix now, so put
Cert_5_2_05_AddressQuery.py in XFAIL on ncp.
Also add a method last_mle_message to find the newest mle; Add a method assertAssignedRouterQuantity to confirm if Leader contains the Route64 TLV with 32 assigned router IDs.
This commit increases the time in waiting for a child to reattach. This
reflects the recent change to add retransmissions to the MLE Child Update
Request message.
After Travis updated its environment, Travis fails distcheck due to insufficient memory. Although OpenThread itself doesn't use much memory, the address sanitizer does.
This commit separates large scale test cases to lower peak memory usage when running certification tests on Travis.
