2007-05-24hush: fix handling of unmatched ${name (without closing '}') -Denis Vlasenko
was eating all remaining input, potentially megabytes. nofork: save/restore die_jmp too nofork: use -2222 instead of -111 as "special" return valur for zero (-111 is used by some applets. -2222 won't fit in exitcode and thus safer)
2007-05-17more compile fixes from randomconfig runDenis Vlasenko

set/save/restore more shared global variables whan call one applet from another

"#ifndef BB_NOMMU" is a double negative

FEATURE_SH_STANDALONE_SHELL => FEATURE_SH_STANDALONE FEATURE_EXEC_PREFER_APPLETS => FEATURE_PREFER_APPLETS Make SH_STANDALONE depend on PREFER_APPLETS. getopt.c: more randomconfig-induced fixes
2007-04-10make compressed help code NOMMU- and NOFORK-friendly -Denis Vlasenko
no forking anymore, bunzip2 unpack routine now does all it in memory.

rename sllep_and_die -> xfunc_die make fflush_stdout_and_exit NOFORK-safe fix some buglets found by randomconfig
2007-04-09make xfunctions optionally longjump instead of exit.Denis Vlasenko
use it for making NOFORK more practical. touch: make it a NOFORK applet

find: use NOFORK/NOEXEC; small -exec buglet also eliminated vfork_daemon_rexec: honor PREFER_APPLETS echo: small size improvements find -exec echo {} \; with PREFER_APPLETS=y runs 4 times faster

fsck: fix bad English in a comment
2007-03-26Attempt to get more applets compile for NOMMU.Denis Vlasenko
TODO_config_nommu documents what I managed to compile so far (yay! msh works! cool). inetd, telnetd, httpd still do not compile. TODO Also make fork(), daemon() produce warnings on compile stage (in addition to erros on link stage).
2007-03-26libbb: rework NOMMU helper API so that it makes more senseDenis Vlasenko
and easier to use. Doesn't compile - need two more commits.
2007-03-24NOMMU re-exec trick shuld not depend on existence of "don't daemonize"Denis Vlasenko
option for every affected applet (and dnsd, for example, don't have one). Thus rework re-exec support to not require it. Code got smaller too.
2007-01-19openvt,getty,vfork_daemon_rexec,mount: tighten up fd cleanup codeDenis Vlasenko
(will close all fd's > 2 on daemonization now) getty: fix "getty -" support, and also do not try to chown/chmod "-" telnetd: fix "lost ctty" bug Yet another attempt on saner function names: bb_sanitize_server_stdio(0/1) -> bb_sanitize_stdio() + bb_daemonize();
