# CLAUDE.md
|
||||
|
||||
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
|
||||
|
||||
## Project Overview
|
||||
|
||||
shadowsocks-libev is a lightweight SOCKS5 proxy written in pure C. Version 3.3.6, licensed under GPLv3.
|
||||
|
||||
## Build Commands
|
||||
|
||||
### CMake (sole build system)
|
||||
|
||||
```bash
|
||||
git submodule update --init --recursive
|
||||
mkdir -p build && cd build
|
||||
cmake ..
|
||||
make
|
||||
sudo make install
|
||||
```
|
||||
|
||||
On macOS, CMake should auto-detect library paths. If needed, specify paths:
|
||||
```bash
|
||||
cmake .. -DCMAKE_PREFIX_PATH="/usr/local/opt/mbedtls;/usr/local/opt/libsodium"
|
||||
```
|
||||
|
||||
CMake outputs binaries to `build/bin/` (static) and `build/shared/bin/` (shared).
|
||||
|
||||
### Build Dependencies
|
||||
|
||||
- cmake (>= 3.2), a C compiler (gcc or clang), pkg-config
|
||||
- libmbedtls, libsodium (>= 1.0.4), libpcre3, libev, libc-ares
|
||||
- asciidoc + xmlto (documentation only)
|
||||
|
||||
### CMake Options
|
||||
|
||||
- `-DWITH_EMBEDDED_SRC=OFF`: use system libcork/libipset/libbloom instead of bundled submodules
|
||||
- `-DWITH_DOC_MAN=OFF`: skip man page generation
|
||||
- `-DENABLE_CONNMARKTOS=ON`: Linux netfilter conntrack QoS support
|
||||
- `-DENABLE_NFTABLES=ON`: nftables firewall integration
|
||||
- `-DDISABLE_SSP=ON`: disable stack protector
|
||||
- `-DBUILD_TESTING=OFF`: disable unit tests
|
||||
|
||||
## Testing
|
||||
|
||||
### Unit Tests (CTest)
|
||||
|
||||
```bash
|
||||
cd build
|
||||
ctest --output-on-failure
|
||||
```
|
||||
|
||||
10 unit test modules cover: base64, buffer, crypto, json, jconf, cache, ppbloom, rule, netutils, utils.
|
||||
|
||||
### Integration Tests
|
||||
|
||||
Integration tests use Python and require `curl` and `dig` to be available:
|
||||
```bash
|
||||
bash tests/test.sh
|
||||
```
|
||||
|
||||
The test harness (`tests/test.py`) starts ss-server, ss-local, and ss-tunnel locally, then runs curl through the SOCKS5 proxy and dig through the tunnel. Each test config in `tests/*.json` exercises a different cipher.
|
||||
|
||||
Run a single cipher test:
|
||||
```bash
|
||||
python tests/test.py --bin build/bin/ -c tests/aes-gcm.json
|
||||
```
|
||||
|
||||
## Code Formatting
|
||||
|
||||
Uses **uncrustify** with the config at `.uncrustify.cfg`. Key settings: 4-space indent, no tabs, 120-column width, K&R brace style (braces on same line).
|
||||
|
||||
## Architecture
|
||||
|
||||
### Binaries (all in `src/`)
|
||||
|
||||
Each binary is compiled with a module define that controls conditional compilation:
|
||||
|
||||
| Binary | Define | Purpose |
|
||||
|---|---|---|
|
||||
| `ss-local` | `MODULE_LOCAL` | SOCKS5 client proxy |
|
||||
| `ss-server` | `MODULE_REMOTE` | Server-side proxy |
|
||||
| `ss-tunnel` | `MODULE_TUNNEL` | Port forwarding tunnel (implies `MODULE_LOCAL`) |
|
||||
| `ss-redir` | `MODULE_REDIR` | Transparent proxy via iptables (Linux only, implies `MODULE_LOCAL`) |
|
||||
| `ss-manager` | `MODULE_MANAGER` | Multi-server manager daemon |
|
||||
|
||||
A shared library `libshadowsocks-libev` is also built from the ss-local sources with `-DLIB_ONLY`. Its public API is in `src/shadowsocks.h`.
|
||||
|
||||
### Source Organization (`src/`)
|
||||
|
||||
**Shared by all binaries:**
|
||||
- `utils.c` - logging, system utilities
|
||||
- `jconf.c` / `json.c` - JSON config file parsing
|
||||
- `netutils.c` - network address utilities
|
||||
- `cache.c` - hash-based LRU connection cache
|
||||
- `udprelay.c` - UDP relay implementation (shared, but uses `#ifdef MODULE_*` for per-binary behavior)
|
||||
|
||||
**Crypto layer** (two parallel implementations behind a common `crypto_t` interface):
|
||||
- `crypto.c` / `crypto.h` - crypto initialization, key derivation (HKDF), buffer management. Defines `crypto_t` with function pointers for encrypt/decrypt.
|
||||
- `stream.c` - stream cipher implementation (CFB mode via mbedTLS)
|
||||
- `aead.c` - AEAD cipher implementation (AES-GCM via mbedTLS, ChaCha20-Poly1305 via libsodium)
|
||||
- `ppbloom.c` - ping-pong bloom filter for nonce replay detection
|
||||
|
||||
**ACL (Access Control Lists):**
|
||||
- `acl.c` / `rule.c` - IP/domain-based routing rules using libipset
|
||||
|
||||
**Plugin support:**
|
||||
- `plugin.c` - SIP003 plugin subprocess management
|
||||
|
||||
### Bundled Submodules
|
||||
|
||||
Three git submodules in the repo root (can be replaced with system libs via `-DWITH_EMBEDDED_SRC=OFF`):
|
||||
- `libcork/` - data structures (dllist, hash-table, buffers)
|
||||
- `libipset/` - IP set operations for ACL
|
||||
- `libbloom/` - bloom filter implementation
|
||||
|
||||
### Event Loop
|
||||
|
||||
All binaries use **libev** for async I/O. The connection lifecycle follows stages defined in `src/common.h`: `STAGE_INIT` -> `STAGE_HANDSHAKE` -> `STAGE_RESOLVE` -> `STAGE_STREAM` -> `STAGE_STOP`. Each binary defines its own `listen_ctx_t`, `server_t`, and `remote_t` structs (note: "server" in `local.h` means the local-side connection, "remote" means the ss-server side).
|
||||
|
||||
### Compiler Flags
|
||||
|
||||
Default flags from `CMakeLists.txt`: `-g -O2 -Wall -Werror -Wno-deprecated-declarations -fno-strict-aliasing -std=gnu99 -D_GNU_SOURCE`
|
||||
|
||||
The `-Werror` flag means all warnings are errors - new code must compile warning-free.
