* test: Speed up by cutting on eye candy and performance test durationStefano Brivio2024-08-151-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have a number of delays when we switch to new layouts that were added to make the tests visually easier to follow, together with blinking status bars. Shorten the delays and avoid blinking the status bar if $FAST is set to 1 (no demo mode). Shorten delays in busy loops to 10ms, instead of 100ms, and skip the one-second fixed delay when we wait for the status of a command. Cut the duration of throughput and latency tests to one second, down from ten. Somewhat surprisingly, the results we get are rather consistent, and not significantly different from what we'd get with 10 seconds. This, together with Podman's commit 20f3e8909e3a ("test/system: pasta_test_do add explicit port check"), cuts the time needed on my setup for full test run from approximately 37 minutes to...: $ time ./run [exited] PASS: 165, FAIL: 0 Log at /home/sbrivio/passt/test/test_logs/test.log real 15m34.253s user 0m0.011s sys 0m0.011s Signed-off-by: Stefano Brivio <sbrivio@redhat.com> Reviewed-by: David Gibson <david@gibson.dropbear.id.au> Tested-by: David Gibson <david@gibson.dropbear.id.au>
* passt: Relicense to GPL 2.0, or any later versionStefano Brivio2023-04-061-1/+1
| | | | | | | | | | | | | | | | | | | In practical terms, passt doesn't benefit from the additional protection offered by the AGPL over the GPL, because it's not suitable to be executed over a computer network. Further, restricting the distribution under the version 3 of the GPL wouldn't provide any practical advantage either, as long as the passt codebase is concerned, and might cause unnecessary compatibility dilemmas.

* test/lib: Move screen-scraping setup and layout functions to _ugly filesStefano Brivio2022-11-041-69/+0
| | | | | | | | | | | I'm going to add yet another one of those, for which I have no quick solution. It's a regression in some sense, but at least if we make this regression more observable and defined, it should be easier to find a comprehensive solution later, within this or another testing framework.

* test: Add log file tests for pasta plus corresponding layout and setupStefano Brivio2022-10-261-0/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To test log files on a tmpfs mount, we need to unshare the mount namespace, which means using a context for the passt pane is not really practical at the moment, as we can't open a shell there, so we would have to encapsulate all the commands under 'unshare -rUm', plus the "inner" pasta command, running in turn a tcp_rr server. It might be worth fixing this by e.g. detecting we are trying to spawn an interactive shell and adding a special path in the context setup with some form of stdin redirection -- I'm not sure it's doable though. For this reason, add a new layout, using a context only for the host pane, while keeping the old command dispatch mechanism for the passt pane. We also need a new setup function that doesn't start pasta: we want to start and restart it with different options. Further, we need a 'pint' directive, to send an interrupt to the passt pane: add that in lib/test. All the tests before the one involving tmpfs and a detached mount namespace were also tested with the context mechanism. To make an eventual conversion easier, pass tcp_crr directly as a command on pasta's command line where feasible. While at it, fix the comment to the teardown_pasta() function. The new test set can be semi-conveniently run as: ./run pasta_options/log_to_file and it checks basic log creation, size of the log file after flooding it with debug entries, rotations, and basic consistency after rotations, on both an existing filesystem and a tmpfs, chosen as it doesn't support collapsing data ranges via fallocate(), hence triggering the fall-back mechanism for logging rotation.

* test: Remove unneccessary pane naming from layout_two_guestsDavid Gibson2022-09-291-4/+0
| | | | | | | | | This loop goes through and gives a numeric label to each pane, even though we name the panes properly shortly thereafter. Looks like a leftover from some earlier version. Remove it.

* test: Use context system for two_guests testsDavid Gibson2022-09-131-11/+4
| | | | | | | | Now that we have all the pieces we need for issuing commands both into namespaces and into guests, we can use those to convert the two_guests to using only the new style context command issue. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* test: Use context system for guest commandsDavid Gibson2022-09-131-3/+1
| | | | | | | | | | | | | | | Extends the context system in the test scripts to allow executing commands within a guest. Do this without requiring an existing network in the guest by using socat to run ssh via a vsock connection. We do need some additional "sleep"s in the tests, because the new faster dispatch means that sometimes we attempt to connect before socat has managed to listen. For now, only use this for the plain "passt" tests. The "passt_in_ns" and other tests have additional complications we still need to deal with.

| | | | | | | | | | Convert the pasta and passt tests to use new-style context execution for the things that run in the "passt" frame.
