# --- 日志配置 ---

# 1. 确保日志目录存在
LOG_DIR = "logs"
if not os.path.exists(LOG_DIR):
    os.makedirs(LOG_DIR)

LOG_FILE = os.path.join(LOG_DIR, "vs_app.log")

# 2. 定义日志格式 (包含时间)
# 格式示例:[2023-10-27 10:30:01] [INFO] [MainThread] [TAG] Message...
LOG_FORMAT = '[%(asctime)s][%(levelname)s][%(threadName)s]%(message)s'
DATE_FORMAT = '%Y-%m-%d %H:%M:%S'

# 3. 获取日志级别
log_level_str = os.environ.get("VSC_LOG_LEVEL", "INFO").upper()
log_level = getattr(logging, log_level_str, logging.INFO)

# 4. 配置日志滚动参数 (支持通过环境变量覆盖)
# 默认单个日志文件大小: 10 MB (10 * 1024 * 1024 bytes)
MAX_BYTES = int(os.environ.get("VSC_LOG_MAX_BYTES", 10 * 1024 * 1024))
# 默认保留的备份文件数量: 5
BACKUP_COUNT = int(os.environ.get("VSC_LOG_BACKUP_COUNT", 10))

# 5. 创建 handlers
# 控制台 handler
console_handler = logging.StreamHandler(sys.stdout)

# 滚动文件 handler
rolling_file_handler = RotatingFileHandler(
    filename=LOG_FILE,
    mode='a',
    maxBytes=MAX_BYTES,
    backupCount=BACKUP_COUNT,
    encoding='utf-8'
)

# 6. 配置 logging (同时输出到控制台和滚动文件)
logging.basicConfig(
    level=log_level,
    format=LOG_FORMAT,
    datefmt=DATE_FORMAT,
    handlers=[
        console_handler,
        rolling_file_handler
    ]
)
