Minutes

=====================================================================
General Discussion
* 24.11 roadmap status:
https://docs.google.com/document/d/1doTZOOpkv4D5P2w6K7fEJpa_CjzrlMl3mCeDBWtxnko/edit
* We should prioritize reviews and merging over further developing at this
time.
* DPDK Release schedule:
   * RC2 is not yet merged. Most likely this will happen November 8.
   * RC3 should be 11/15
   * Release should be 11/27

=====================================================================
Patch discussions
* DTS Docs bugfix: moves DTS docs to the same dir as dpdk docs
   * Paul has provided this patch this morning:
https://patchwork.dpdk.org/project/dpdk/patch/20241025103520.394951-1-paul.szczepanek@arm.com/
   * We have been told to merge this to next-dts (previously we thought it
was going direct to main), so Paul is applying this to next-dts after this
meeting.
* Copying DPDK build to SUT
   * Merged last week, and was tested with tarball and dpdk tree options on
both test engine node and SUT node
* Pydantic patchseries:
   * https://patchwork.dpdk.org/project/dpdk/list/?series=32823
   * V5 was submitted with some improvements, including how dataclass
fields display in the API docs (prevents field duplication)
      * Dts docs building instructions are to build the docs from the
poetry environment (with those dependencies installed)
      * Patrick did not build api docs from this patch but can do so if
needed
   * Removes warlock dependency from poetry
   * Patrick will both build the api docs outside of poetry, and do a
sanity check testrun, then he will apply to next-dts today.
* Some issues observed with types in scapy 2.6 and above
   * We should most likely pin this (and everything) instead of just
setting a minimal version supported via poetry
* Patrick will continue merging testsuites, including mac_filter,
dual_vlan, dynamic_config (needs to be rebased for new testpmd_shell
functions introduced in the capabilities series), blocklist and l2fwd if
submitted, etc.
   * L2fwd and blocklist should be updated by UNH guys and merged
* Nick’s patch for removing excess config attributes:
   * Nick can text Luca for pydantic knowledge as needed to speed this up.
* Updating mypy results in some linter warnings reported
   * This can be addressed in 25.03
* Per testsuite configs: Luca has something to submit for this
* Asyncsniffer bug seen with intel nics
   * Nick submitted a patch which just adds a sleep 1000ms before sniffing
   * Paul is advocating for a deterministic approach in which the sequence
of events for triggering the sniffer and sending packets is changed.
      * Is there a programmatic way of verifying the readiness of the
asyncsniffer?
      * There may be a listen with some return code we can use (check the
scapy api). May be possible to keep probing this until we get the right
answer.

=====================================================================
Bugzilla discussions
* We should add a bugzilla ticket for discussing fuzz testing in DTS
   * Patrick can add
* API docs do not include the testsuites, so this needs to be added
   * Patrick make a ticket for this

=====================================================================
Any other business
* Next meeting Nov 21, 2024
