just build relevant source and use xxx_main functions.
build system: add a special case when we have exactly one applet enabled
(makes "true", "false", "basename" REALLY tiny).
getopt32: do not use stdio.

Minimal hush is ~9k now (lash is ~7k).

config system: clarify PREFER_APPLETS/SH_STANDALONE effects in help text
|
|
|
|
|
|
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

so rename stuff accordingly.
|
|
less-known keys (e.g. Ctrl-B/E/F)

redundant, but it made the menuconfig shortcut mechanism mostly
useless, since so many of the entries started with 'E'.
|
|
moved the contents of libbb/bb_echo.c back into coreutils/echo.c,
which is a more reasonable place for them than libbb. this
forces anyone who wants echo and test to be builtin to ash to
also have them available as applets. their cost is very small,
and the number of people who wouldn't want them as applets is
also very small.
added warning about shell builtins vs. CONFIG_FEATURE_SH_STANDALONE_SHELL,
which conflicts with their use.
thanks to nathanael copa for debugging help.
some string size optimization in test.c may have been lost with
this commit, but this is a good new baseline.

to do it in Config.in.
|
|
|

|

in the menu hierarchy or else make allnoconfig winds up leaving whatever the
select points to as "y". (In this case, "make allnoconfig" is leaving
CONFIG_TEST as "y".)
|
|
"depends on CONFIG_BAR" instead of the if !CONFIG_FOO ...default y stanza.

Summary 0000242: ash: read -t broken
this also implements -n and -s options to read. (they're configured
together because most of their code is in common, and separating them
seemed silly.
|
|
2) but expand PS# as config option
3) correct kill error message again
4) remove show "line number" for interactive run (patch pending for dash)
|
|
echo applet into libbb, and now call bb_echo() from both echo.c
and ash.c

0000025: vi-editing mode for ash
|
|
Oct/21/2004 on the busybox mailing list. Edited his code a little to keep syntax highlighers happy and make it optional when CONFIG_ASH_TIMEOUT is defined
|
|
|
|
|
|
The updated patch adds a config option to explicitely enable 64 bit
arithmetic.
Also it removes the arith prototype from libbb.h as it is not used
outside of ash.
Bastian
this patch has been slightly modified by Erik for cleanliness.

stupid and didn't work properly anyways.

have checked in. Vladimir writes:
Your patch have many problem.
1. You always added + time(). This cannot reset RANDOM=value for debuging
with
replay sequential.
2. Hmm. I examine bash 2.04 source. This pseudorandom generator use low bits
of
counter value. You use high bits. This make bad pseudorandom values after
have
0-value. For example, if + time() do remove, your generator always return 0
after
first generate 0.
3. Memory leak per call. Use ash-unlike unecessary bb_strdup function.
4. Unsupport show last $RANDOM value for "set" and "export" command.
5. Bloat code. Busybox-unlike patch - added unstandart feature as default
hardcode.
Last patch attached.
Erik, why you apply Paul patch with have 5-th point problem? :(
Last patch have ash change xwrite() to fresh libbb/bb_full_write interfase
(haved loop after EINTR).
