Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to This change only hardens tests and updates comments, so it does not change production behavior. One comment still inaccurately describes the boolean argument and could mislead future maintenance; the PR is mergeable with explicit owner awareness or a follow-up correction.

- Line 793: Update the comment near gate_for to accurately state that it
receives a boolean, while event loops derive the v2 condition from
NostrKind::from(crate::config::constants::DM_EVENT_KIND) before calling it and
accept_event uses that value as accepted_kind.

`assert_eq!(gate_for(true).is_some(), SpamGate::global().is_some())` compares `gate_for` with itself: it returns exactly that global. Until something installs a gate in the process both sides are `None` and the assert passes without checking anything — making `gate_for(true)` return `None` unconditionally went undetected. The two sides are also read at different instants while tests run in parallel, so an install landing between them yields a spurious `false == true`. Install the gate in the test and assert `is_some()` outright. That forces a second change. `install_global_then_second_install_is_rejected` required being the process's first install, which only held while it was the sole installer. Adopt what `PriceManager`'s equivalent test already does — ignore the install result and pin the contract that survives any ordering: a gate is exposed, and a second install is refused, not a panic. Without it, `--test-threads=1` runs `app::…` first and that test fails. Also refresh a comment naming `is_v2`, a variable the event loops no longer have since MostroP2P#892; they pass the condition to `gate_for`. Closes MostroP2P#913

Closes #913.
Two non-blocking nits from the review of #892. Tests and comments only, no
runtime change.
The v2 arm was not pinned
gate_for(true)returns that global, so the assert compares the functionwith itself. Until something installs a gate in the process both sides are
Noneand it passes without checking anything. The two sides are also read atdifferent instants while tests run in parallel, so an install landing between
them yields a spurious
false == true.Confirmed empirically: with
gate_forrewritten to returnNoneunconditionally — the v2-only policy disabled outright — the old test still
passed. With this change it fails on
v2 must resolve the installed gate.The fix installs the gate and asserts
is_some()directly.Why
spam_gate.rschanges tooinstall_global_then_second_install_is_rejectedrequired being the process'sfirst install (
assert!(first.is_ok(), "first install must succeed")), whichonly held while it was the sole installer of this
OnceLock. Once the testabove installs as well, whichever loses the race fails — under
--test-threads=1tests run alphabetically, soapp::…installs first andthat test breaks. Verified: applying only the
app.rschange fails there withfirst install must succeed.So it adopts what
PriceManager's equivalent test already does(
price/manager.rs,install_global_accepts_once_then_refuses): ignore theinstall result and pin the contract that survives any ordering — a gate is
exposed, and a second install is refused rather than panicking. What is given
up, "the process's first install returns
Ok", is not deterministicallytestable in a binary with parallel tests, and the
pricemodule already madethat trade.
Stale comment
A comment named
is_v2, a variable the event loops no longer have since #892;they pass the condition to
gate_for.Verification
Green both in parallel and under
--test-threads=1, and each of the two testspasses in isolation.
