Build & Run

# Standalone (no ACE/MySQL needed):
cd tests && mkdir build && cd build
cmake .. && cmake --build .
./mangos_tests   # 902 tests, ~5ms

# Full server build requires: MySQL/MariaDB dev, OpenSSL dev
# Submodules must be initialized: git submodule update --init --recursive

Test Plan

  • All 902 tests compile and pass (0 failures, ~5ms)
  • Zero external dependencies — standalone C++17
  • TEST_F fixture macro with SetUp()/TearDown() lifecycle
  • Stress tests verify edge cases: NaN, overflow, underflow, degenerate inputs
  • Submodules (SD3, Eluna) checked out successfully
  • Full server build blocked by MySQL dev package unavailability in CI environment

Adds a CMake option -DMANGOS_TEST_MODE=ON that allows the server to
start without DBC files, map files, or populated databases. When
enabled, the server skips map/vmap validation, DBC store loading, DB
version checks, and all game data loading, allowing it to boot with
just empty MySQL databases and listen for connections on port 8085.

https://claude.ai/code/session_01BASLpNitMR8fr4c1HUQHdP
Fix World::Update() crash (SIGFPE) caused by uninitialized timers and
MapManager/BattleGround/GameEvent systems when running in test mode.
Skip map updates, daily quest resets, game events, terrain updates, and
uptime DB writes in test mode since those systems are not initialized.

Add Python-based adversarial network stress test suite (30 tests) that
attacks the running server with: rapid connect/disconnect, simultaneous
connections, malformed packets, garbage opcodes, 1MB binary floods,
fake auth challenges, oversized account names, concurrent multi-thread
floods, slowloris attacks, and 1000x connect-read-close cycles.

Server survives all 30 attack vectors while running in test mode.

print(f"Server is alive on {SERVER_HOST}:{SERVER_PORT}\n")

# Collect all test functions
tests = [v for v in globals().values() if callable(v) and hasattr(v, '__name__') and v.__name__.startswith(("test_", "Test"))]
Mock client (tests/mock_client.py):
- Full WoW 4.3.4 protocol implementation: correct CMSG_AUTH_SESSION
  byte layout mirroring WorldSocket::HandleAuthSession() read order,
  BuiltNumberClient as uint16, packed account name length encoding
- 6 normal mechanic tests: auth OK/unknown/wrong-build, char enum,
  ping-pong, 10 sequential pings
- 17 adversarial tests: pre-auth opcodes, double auth, game packets
  before login, overflow pings, length mismatch, zero-body opcodes,
  50x rapid auth cycle, 10x concurrent auth, 100 concurrent sessions,
  null GUID login, logout without login, 200 garbage opcodes, 1000
  ping flood — all 23 tests pass, server stays alive throughout

Server fixes:
- WorldSocket::CloseSocket / handle_close: flush m_OutBuffer before
  closing so error responses (AUTH_UNKNOWN_ACCOUNT, etc.) actually
  reach the client instead of being silently dropped
- WorldSocket::close: revert accidental flush added to wrong method
- CharacterHandler::HandlePlayerLoginOpcode: reset m_playerLoading on
  ByteBufferException so empty-body CMSG_PLAYER_LOGIN can't permanently
  lock out the account from re-login
- CharacterHandler::HandlePlayerLoginCallback: skip callback if session
  is no longer in loading state, preventing a stale async DB callback
  from kicking a freshly reconnected session
- WorldSession::IsSocketClosed / World::RemoveSession: allow session
  replacement when the old session's socket is already closed but
  m_playerLoading is still true (client disconnected mid-character-load)

…ilures

The test suite exposed 2 failing stress tests (DamageWithMaxUint32,
MaxQuestXP) caused by float-to-uint32 casts overflowing when float
values exceed UINT32_MAX (4294967296.0f). This is undefined behavior
in C++ and silently produces 0 on common platforms.

Added SafeUInt32FromFloat/SafeUInt32FromDouble helpers to Util.h that
clamp to [0, UINT32_MAX] before casting. Applied the fix across 20+
locations in the server source where the same pattern existed:
- Damage sharing (Unit.cpp)
- Shield block calculation (Unit.cpp)
- SetHealthPercent (Unit.cpp)
- Combat rating damage reduction (Unit.cpp)
- XP modifiers from auras (Player.cpp)
- Quest/exploration XP with rate multipliers (Player.cpp)
- Gold/loot drops with rate multipliers (Player.cpp, LootMgr.cpp)
- Spell heal/damage percent-of-max-health (SpellAuras.cpp, SpellEffects.cpp)
- Mana regen percent calculations (SpellAuras.cpp)
- Group XP distribution (Group.cpp)
- Creature health regen (Creature.cpp)
- Durability repair costs (Player.cpp)

All 902 tests now pass (was 900/902).

- sql/setup_mariadb.sql: Full schema for realmd, character3, and mangos3
  databases with test accounts and core tables (InnoDB, utf8)
- tests/test_mariadb_stress.py: 28 adversarial tests targeting MariaDB
  directly — connection pool exhaustion, transaction deadlocks, SQL
  injection prevention, concurrent writes, InnoDB row lock contention,
  binary data, charset stress, schema DDL under load
- tests/test_mock_client_db_exploits.py: 20 protocol-level exploit tests
  that trigger database operations — SQL injection via character names,
  guild names, WHOIS; concurrent char enum floods; thundering herd;
  session teardown race conditions during async DB writes
- tests/test_DatabaseStress.cpp: 35 C++ unit tests for connection string
  parsing, SQL escape routines, query formatting, simulated connection
  pool, async query queue, transaction lifecycle, GUID uniqueness, and
  query result memory stress (all under heavy concurrency)

All tests pass: 28/28 Python DB tests, 938/938 C++ unit tests.

Vulnerabilities fixed:

1. CRITICAL — Memory exhaustion via m_addonSize (WorldSocket.cpp:903)
   Client could send m_addonSize=0xFFFFFFFF triggering a 4GB allocation.
   Fix: Cap addon data at ~1MB (0xFFFFF) and reject oversized packets.

2. HIGH — SQL injection in character rename (CharacterHandler.cpp:1228)
   HandleChangePlayerNameOpcodeCallBack used unescaped newname.c_str()
   directly in PExecute UPDATE query. The escaped_newname was prepared
   in the calling function but never passed to the callback.
   Fix: Escape newname before use in the UPDATE statement.

3. MEDIUM — Unescaped IP in ban-check SQL (WorldSocket.cpp:1035)
   GetRemoteAddress() was interpolated directly into a SQL query with
   '%s' format. While typically safe (ACE returns dotted-quad), IPv6 or
   proxy scenarios could allow injection.
   Fix: Escape the IP string before interpolation.

4. MEDIUM — No packet rate limiting (WorldSocket)
   No per-connection packet rate limit existed. Clients could flood
   the server with unlimited packets/sec, exhausting CPU and DB pool.
   Fix: Add 300 packets/sec rate limiter per connection with automatic
   disconnect on violation.

Also:
- Complete character3 schema (20+ missing tables that caused SQL errors
  under concurrent load: character_pet, mail, arena_team_member, etc.)
- Update setup_mariadb.sql with all tables
- Adjust concurrent char enum test threshold for rate limiting

All 73 tests pass: 23 mock client + 20 DB exploit + 30 stress tests.

Findings and fixes from running DB setup, normal game actions, and
adversarial exploit tests against MariaDB:

Source code fixes:
- AuthSocket.cpp: snprintf used sizeof(tmp)=24 on a 64-byte buffer — fix
  to use sizeof(tmp)=64 so patch filenames can never be truncated silently
- Chat.cpp: three PSendSysMessage vsnprintf buffers doubled from 2048→4096
  and use sizeof(str) instead of a hardcoded literal; add explicit NUL
  termination after vsnprintf for defense in depth

Schema fixes (setup_mariadb.sql):
- characters.money: INT UNSIGNED → BIGINT UNSIGNED (INT max is ~4.2B but
  game's MAX_MONEY_AMOUNT is 9,999,999,999 — schema bug caused truncation)
- mail.money, mail.cod: same INT→BIGINT fix

New: sql/security_hardening.sql
- Reduce mangos DB user from ALL PRIVILEGES to SELECT/INSERT/UPDATE/DELETE
  (prevents DROP, CREATE, ALTER, GRANT via compromised game server)
- CHECK constraints: money ≤ 9,999,999,999, level 0–85, item count > 0,
  guild name 1–24 chars, mail money cap
- Foreign keys with ON DELETE CASCADE on character_inventory, _spell,
  _aura, _queststatus — prevents orphaned records and item ghost exploits
- Security tables: account_login_attempts, ip_rate_limit, security_audit_log

New: tests/test_security_hardening.py — 37-test suite validating all of
the above; all 37 pass. Also: all 28 MariaDB adversarial stress tests pass.
