TODO list for busybox in no particular order. Just because something
|
|
is listed here doesn't mean that it is going to be added to busybox,
|
|
or that doing so is even a good idea. It just means that I _might_ get
|
|
around to it some time. If you have any good ideas, please let me know.
|
|
|
|
* login/sulogin/passwd/getty/etc are part of tinylogin, and so are not
|
|
needed or wanted in busybox (or else I'd have to link to libcrypt).
|
|
|
|
* We _were_ going to split networking apps into a new package called
|
|
netkit-tiny. Per discussions on the mailing list, this isn't going
|
|
to happen. False alarm. Sorry about the confusion.
|
|
|
|
* The default busybox shell, lash, is really too weak for serious use,
|
|
although it is possible to run many simple systems with it. BusyBox
|
|
0.52 now contains a rewritten shell, hush, which understands most
|
|
Bourne grammar, with only about a 4 Kbyte binary size penalty. You can
|
|
engage hush at pre-compile time by "ln -sf hush.c sh.c; touch hush.c".
|
|
Hush is young, and has plenty of bugs to shake out, so think twice before
|
|
using it for production systems. We welcome bug reports and patches.

|
Possible apps to include some time:
|
|
|
|
* hwclock
|
|
* group/commonize strings, remove dups (for i18n, l10n)
|
|

|
|
With sysvinit, reboot, poweroff and halt all used a named pipe,
|
|
/dev/initctl, to communicate with the init process. Busybox
|
|
currently uses signals to communicate with init. This makes
|
|
busybox incompatible with sysvinit. We should probably use
|
|
a named pipe as well so we can be compatible.
|
|
|
|
-----------------------
|
|
|
|
Run the following:
|
|
|
|
rm -f busybox && make LDFLAGS+=-nostdlib 2>&1 | \
|
|
sed -ne 's/.*undefined reference to `\(.*\)..*/\1/gp' | sort | uniq
|
|
|
|
reveals the list of all external (i.e. libc) things that BusyBox depends on.
|
|
It would be a very nice thing to reduce this list to an absolute minimum, to
|
|
reduce the footprint of busybox, especially when staticly linking with
|
|
libraries such as uClibc.
|
|
|
|
-----------------------
|
|
|
|
Compile with debugging on, run 'nm --size-sort ./busybox'
|
|
and then start with the biggest things and make them smaller...
|
|
|
|
-----------------------
|
|
|
|
du.c probably ought to have an -x switch like GNU du does...
|
|
|
|
-----------------------
|
|
|
|
xargs could use a -l option
|
