Combines five dep-and-build changes that all flow from the libp2p v2.0.0
upgrade and the move to the extracted libp2p_mix / mix-rln plugin stack:
waku.nimble:
* libp2p: ff8d51857 -> c43199378 (release/v2.0.0 tip; sha-pinned until
vacp2p cuts a v2.0.0 tag).
* Drop the bare `zlib < 0.2` cap — no longer needed by the upgraded
libp2p.
* websock: bare ">= 0.4.0" — replaces the d4cd68b URL+SHA workaround
that pinned through a libp2p commit-specific websock SHA.
* nim-json-rpc: switch to chaitanyaprem/nim-json-rpc#f05fad25 — relaxes
websock cap to allow >=0.4.0. TODO: revert to status-im/nim-json-rpc
once status-im/nim-json-rpc#277 merges and a tag is cut.
* lsquic: bare ">= 0.4.1" (drops URL form).
* Add mix-rln-spam-protection-plugin pin (23b278b4) and nim-libp2p-mix
pin (50c4ab4f — PR #14 HEAD); the plugin pins the same libp2p_mix
SHA so the diamond dep collapses to a single source.
waku/factory/waku.nim:
* Explicit HPService.setup(switch) / AutonatService.setup(switch)
calls. libp2p v2.0.0's Service lifecycle refactor (libp2p#2462)
removed switch.start's auto-setup loop, so any caller that assigns
directly to switch.services (we do) is responsible for calling
setup() themselves. Without it, AutonatService.addressMapper stays
nil and peerInfo.expandAddrs SIGSEGVs during start(). Wrapped in
try/except for ServiceSetupError so a setup failure surfaces as a
logged error rather than a crash.
Build / scripts:
* scripts/build_rln_mix.sh removed and Makefile simplified — librln
is now a single shared archive built from zerokit's `stateless`
features (no separate librln_mix archive).
* simulations/mixnet/build_setup.sh + setup_credentials.nim updated
to use librln_v2.0.2.a directly and run RLN keystore setup before
nodes start.
Validated:
* Cold local-cache nimble setup --localdeps -y.
* wakunode2 and chat2mix link cleanly.
* Mixnet roundtrip sim: [PASS] bob received message from alice.
* RLN proof generation + verification on every in-path mix node:
5 gen_called == 5 verified, 0 SPAM_PROOF_* errors.
* properly pass userMessageLimit to OnchainGroupManager
* waku.nimble 2.2.4 Nim compiler
* rm stew/shims/net import
* change ValidIpAddress.init with parseIpAddress
* fix serialize for zerokit
* group_manager: separate if statements
* protocol_types: add encode UInt32 with zeros up to 32 bytes
* windows build: skip libunwind build and rm libunwind.a inlcusion step
* bump nph to overcome the compilation issues with 2.2.x
* bump nim-libp2p to v1.10.1
* undo apt install libpcre (not circuit-relay related.)
* nat.nim: protect against possible exceptions when calling getExternalIP
* new external CLI argument, isRelayClient
* waku factory change to mount circuit hop proto by default
* waku_node: move autonat_service to a separate module
