From d472476caa0f807d8408aac2e96c42e3754cc3dd Mon Sep 17 00:00:00 2001 From: Stefano Brivio Date: Fri, 7 Oct 2022 02:16:08 +0200 Subject: test: Add log file tests for pasta plus corresponding layout and setup 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.
