Subject: - fix : reload a bad configuration file doesn't kill director any more
X-Git-Tag: Release-2.0.0~891
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=38968fcbc46d46096f95662efdb4e4d307369efe;p=bacula%2Fbacula

- fix : reload a bad configuration file doesn't kill director any more
	o add an extra field to LEX err_type (M_ERROR, M_ERROR_TERM...)
	o add lex_set_default_error_handler() to set lex->err_type
	o add an extra option (message level) to parse_config()
