T7948: always call setUp() and tearDown() base class methods

2025-10-21T19:03:16+00:00

While working on task T7664 (FRR 10.4 upgrade), I identified the need for additional validation and safeguards around the FRR management daemon. The most appropriate place for this logic is in the setUp() and tearDown() methods of the smoketest base class, VyOSUnitTestSHIM. However, during implementation, it became apparent that test cases do not consistently invoke the base class's setup and teardown methods. This inconsistency complicates the process of capturing the FRR mgmtd PID at the start of a test and verifying that it remains unchanged by the end - a key step in detecting crashes or unexpected terminations (e.g., SIGSEGV) of the FRR management daemon during tests.

smoketest: T7858: make failfast main argument dynamic

2025-09-30T15:19:06+00:00

When smoketest debugging is enabled (by creating the file /tmp/vyos.smoketest.debug), all available smoketests will fail fast instead of running to completion. This helps reduce test time when something is broken or undergoing refactoring, as it avoids waiting for the full test suite to finish.

T7591: remove copyright years from source files

2025-06-28T21:16:52+00:00

The legal team says years are not necessary so we can go ahead with it, since it will simplify backporting. Automatically removed using: git ls-files | grep -v libvyosconfig | xargs sed -i -E \ 's/^# Copyright (19|20)[0-9]{2}(-[0-9]{4})? VyOS maintainers.*/# Copyright VyOS maintainers and contributors /g' In addition we will error-out during "make" if someone re-adds a legacy copyright notice

* T5195: move run, cmd, call, rc_cmd helper to vyos.utils.process * T5195: use read_file and write_file implementation from vyos.utils.file Changed code automatically using: find . -type f -not -path '*/\.*' -exec sed -i 's/^from vyos.util import read_file$/from vyos.utils.file import read_file/g' {} + find . -type f -not -path '*/\.*' -exec sed -i 's/^from vyos.util import write_file$/from vyos.utils.file import write_file/g' {} + * T5195: move chmod* helpers to vyos.utils.permission * T5195: use colon_separated_to_dict from vyos.utils.dict * T5195: move is_systemd_service_* to vyos.utils.process * T5195: fix boot issues with missing imports * T5195: move dict_search_* helpers to vyos.utils.dict * T5195: move network helpers to vyos.utils.network * T5195: move commit_* helpers to vyos.utils.commit * T5195: move user I/O helpers to vyos.utils.io

T5125: Add op-mode for sFlow based on hsflowd

Add op-mode for sFlow based on hsflowd "show sflow" Add machine readable format '--raw' and formatted output

T5086: Fix sflow fix default values for server

2023-03-17T18:56:47+00:00

We drop default values 'port' but don't set it again per server Fix it

T5086: Add sFlow drop-monitor-limit option

2023-03-17T12:43:13+00:00

hsflowd will export the headers of dropped packets (along with the name of the function in the Linux kernel where that skb was dropped) as part of the standard sFlow feed. This measurement complements the sFlow packet sampling and counter-telemetry well because it provides visibility into the traffic that is not flowing. Very helpful for troubleshooting. The limit (a rate limit max of N drops per second sent out in the sFlow datagrams) is the parameter you would set in the CLI. set system sflow drop-monitor-limit 50
