Three small classes of fix across 12 test files (uncovered by a local
`nim c` sweep of tests/all_tests_common.nim + tests/all_tests_waku.nim):
1. `rng` no longer auto-calls when used as an argument: libp2p v2.0.0
exports its own `rng` symbol (SwitchBuilder field), so Nim's resolver
sees the testlib `common.rng` template ambiguously and stops auto-
calling it. Add explicit `()`:
- tests/test_helpers.nim
- tests/waku_filter_v2/waku_filter_utils.nim
- tests/waku_lightpush/lightpush_utils.nim
- tests/waku_lightpush_legacy/lightpush_utils.nim
- tests/node/test_wakunode_filter.nim
- tests/waku_store/store_utils.nim
2. `PeerId.random()` zero-arg form removed in v2.0.0; new signature
takes `rng: Rng`. Add `newRng()` + `libp2p/crypto/crypto` import:
- tests/common/test_requestratelimiter.nim
- tests/common/test_ratelimit_setting.nim
3. `some()` ambiguity vs `Opt.some` — files that don't directly
`import std/options` get `Opt.some` template only, breaking calls
intended for `Option[T]`. Add `std/options` to imports:
- tests/waku_store/test_wakunode_store.nim
- tests/waku_relay/test_wakunode_relay.nim
4. Two more API removals:
- tests/testlib/wakunode.nim — `builders.MaxConnections` was removed;
use `DefaultMaxConnections` from `libp2p/connmanager`.
- tests/waku_rln_relay/utils_onchain.nim — `keys.PrivateKey.random
(rng[])` `rng` ambiguous between testlib/common and eth/keys
exports; qualify as `common.rng()[]`.
There are still more test-compile errors past this point — this is
incremental progress, not a complete v2.0.0 test-suite migration.
* Enhanced peer-ex protocol - added rate limiting, added response status and desc to the rpc
* Better error result handling for PeerEx request, adjusted tests
* Refactored RateLimit configuration option for better CLI UX - now possible to set separate limits per protocol. Adjusted mountings. Added and adjusted tests
* Fix libwaku due to changes of error return type of fetchPeerExchangePeers
* Fix rate limit setting tests due to changed defaults
* Introduce new gauge to help dasboard effectively show current rate limit applied for protocol
* Adjust timeing in filter rate limit test to let macos CI test run ok.
* Address review findings, namings, error logs, removed left-overs
* Changes to reflect latest spec agreement and changes. PeerExchange RPC is changed the now respond structure will contain status_code and status_desc.
