Proof of concept mechanical port of ircnet/ircd to Rust as part of a bit about C being insecure for network services
1# cargo-nextest configuration — https://nexte.st/docs/configuration/
2#
3# Why this exists: `cargo test` runs each test *binary* serially (libtest only
4# parallelizes within a binary), so the boot-level golden suite — ~200 binaries,
5# each booting a real leveva daemon — runs end-to-end serially (~10 min). nextest
6# runs every test as its own process, parallelizing across binaries *and* tests.
7#
8# This is only safe because the golden harness (leveva/tests/harness/mod.rs) boots
9# each fixture on a freshly-reserved **ephemeral** port instead of the old shared
10# 16700-under-a-global-lock; with that, the wall-clock floor becomes the single
11# slowest test rather than the sum of all of them.
12
13# The boot-level golden tests each spawn a single-threaded leveva daemon and drive
14# barrier-paced clients. Cap how many run at once (independent of `test-threads`)
15# so the daemons stay responsive and do not miss a client's read window under load.
16# The fast lib unit tests are not in this group, so they still run at full width.
17# Raise/lower this on a bigger/smaller box; the harness also enforces a CPU-count
18# semaphore as a backstop, so this never needs to exceed the core count.

23# Only the daemon-booting boot-level tests — every one lives in a binary named
