From 2d78aadfd603fab9a9342b1281ad1d46ad82cf1d Mon Sep 17 00:00:00 2001 From: Your Name Date: Tue, 19 May 2026 04:10:12 +0530 Subject: feat: relay hardening — restore build, add tests, negentropy adapter MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Restores build broken by eeb9d2d (cvm-relay-stability removed deps): - CMakeLists.txt: restore display.c, font.c, local_relay.c, relay_selector.c, sync_manager.c, axs15231b, qrcode, wisp_relay - tollgate_main.c: restore display.h, local_relay.h, relay_selector.h, sync_manager.h includes and display calls - cvm_server.c: kept master's keepalive/timeout/ping-pong fixes New test infrastructure: - test-local-relay, test-relay-nip11, test-cvm-roundtrip, test-cvm-mcp, test-cross-board make targets - test-cvm-roundtrip.mjs: MCP get_config + get_balance via public relay - test-cross-board.mjs: cross-board payment test - test-cvm-mcp-relay.mjs: kept from master New unit tests (35 tests): - test_display.c: 22 tests for escape_wifi_field - test_negentropy_adapter.c: 13 tests for negentropy adapter New modules: - negentropy_adapter.c/h: NIP-77 adapter skeleton Docs: - AGENTS.md: display module docs, new test commands - RELAY_HARDENING_PLAN.md: hardening checklist - RELAY_HARDENING_MERGE.md: merge plan and checklist Cleanup: - Removed CHECKLIST-CVM-RELAY.md, PLAN-SQUASH-MERGE.md (stale planning docs) - Removed components/esp-miner submodule Host unit tests: 63/63 pass --- tests/unit/Makefile | 8 ++- tests/unit/test_display.c | 128 +++++++++++++++++++++++++++++++++ tests/unit/test_negentropy_adapter.c | 136 +++++++++++++++++++++++++++++++++++ 3 files changed, 271 insertions(+), 1 deletion(-) create mode 100644 tests/unit/test_display.c create mode 100644 tests/unit/test_negentropy_adapter.c (limited to 'tests/unit') diff --git a/tests/unit/Makefile b/tests/unit/Makefile index 7ebc3b2..6d13e4d 100644 --- a/tests/unit/Makefile +++ b/tests/unit/Makefile @@ -22,7 +22,7 @@ LDFLAGS := -lmbedcrypto -lcjson -lm SECP256K1_OBJ := secp256k1.o precomputed_ecmult.o precomputed_ecmult_gen.o -TESTS := test_geohash test_identity test_nostr_event test_cashu test_session test_tollgate_client test_lnurl_pay test_lightning_payout test_mcp_handler test_nip04 test_cvm_server +TESTS := test_geohash test_identity test_nostr_event test_cashu test_session test_tollgate_client test_lnurl_pay test_lightning_payout test_mcp_handler test_nip04 test_cvm_server test_display test_negentropy_adapter .PHONY: all test clean $(TESTS) @@ -81,5 +81,11 @@ test_nip04: test_nip04.c $(REPO_ROOT)/main/nip04.c $(SECP256K1_OBJ) test_cvm_server: test_cvm_server.c $(CC) $(CFLAGS) $< -o $@ $(LDFLAGS) +test_display: test_display.c + $(CC) $(CFLAGS) $< -o $@ $(LDFLAGS) + +test_negentropy_adapter: test_negentropy_adapter.c + $(CC) $(CFLAGS) $< -o $@ $(LDFLAGS) + clean: rm -f $(TESTS) $(SECP256K1_OBJ) diff --git a/tests/unit/test_display.c b/tests/unit/test_display.c new file mode 100644 index 0000000..81f67a7 --- /dev/null +++ b/tests/unit/test_display.c @@ -0,0 +1,128 @@ +#include "test_framework.h" +#include +#include + +static int escape_wifi_field(const char *src, char *dst, int dst_size) { + int si = 0, di = 0;
