2008-07-26fix several problems with config parser:Denis Vlasenko
a bug where it underflows the string a bug where it never frees parser_t struct make read_config() return 0 if parser is NULL, make config_close() accept and ignore NULL parser - eliminates many if() blocks reverse the sense of parser bit flags - negative flags are harder to grok. hexdump: revert the change to use config parser, it is BIGGER and also requires additional quirks in parser *: explicitly use PARSER_NORMAL instead of 0 function old new delta login_main 1575 1596 +21 config_close 18 29 +11 bbunpack 383 391 +8 qgravechar 106 109 +3 rtnl_tab_initialize 121 117 -4 expand 1697 1693 -4 man_main 717 712 -5 nameif_main 674 668 -6 hexdump_main 597 591 -6 read_config 217 209 -8 dnsd_main 1478 1470 -8 sysctl_main 203 189 -14 config_open2 44 25 -19 make_device 1177 1141 -36 config_read 597 549 -48 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 4/11 up/down: 43/-158) Total: -115 bytes
