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
2007-04-28hush: fix nofork + ctrl-Z clobbering of globalsDenis Vlasenko
2007-04-14hush: use NOFORK applets as appropriate. Net reduction of code size.Denis Vlasenko
2007-04-12pass a copy of argv[i] to NOFORK applets (they may permute it etc).Denis Vlasenko
set/save/restore more shared global variables whan call one applet from another

2007-04-11add more convenient defines for [NO]MMU:Denis Vlasenko
"#ifndef BB_NOMMU" is a double negative
2007-04-10random NOMMU fixes. compressed --help really does work for NOMMU! /me happyDenis Vlasenko
2007-04-10Rename two config options:Denis Vlasenko
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
2007-04-09factor out NOFORK/NOEXEC code from find. Use it for xargs too.Denis Vlasenko

2007-04-09Implement first instance of NOFORK applet - echoDenis Vlasenko
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
2007-03-26zcip: make it work on NOMMU (+ improve NOMMU support machinery)Denis Vlasenko
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();

2006-06-16Revert svn 15333. If you vfork, you must either exec or exit. (The parent isRob Landley
blocked until you do so.)
2006-06-07sometimes daemonizing and vfork()/exit() is okMike Frysinger
2006-05-31- s/defined(__uClinux__)/BB_NOMMU/Bernhard Reutner-Fischer
This needs a second pass to: + add bb_daemon(unsigned char no_chdir, unsigned char no_close, const char*flag) + eventually globally export argc and argv, so we don't need to pass it to bb_daemon().
