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 in libcrypt).
|
|
|
|
* Networking apps are probably going to be split out some time soon into a
|
|
separate package (named perhaps tiny-netkit?). This currently includes
|
|
hostid, hostname, mnc, and ping.
|
|
|
|

-----------
|
|
|
|
* Allow tar to create archives with sockets, devices, and other special files
|
|
* Make insmod actually work
|
|
* dnsdomainname
|
|
* traceroute/netstat
|
|
* rdate
|
|
* hwclock
|
|
* killall
|
|
* stty
|
|
* tr
|
|
* cut
|
|
* expr (maybe?) (ash builtin?)

-----------------------
|
|
|
|
Compile with debugging on, run 'nm --size-sort ./busybox'
|
|
and then start with the biggest things and make them smaller...
|
|
|
|
|
|
-----------------------
|
|
|
|
|
|
busybox.defs.h is too big and hard to follow.
|
|
|
|
I either need to add a better build system (like the Linux kernel?)
|
|
or I need to split up busybox.defs.h into coherent chunks (i.e.
|
|
busybox.defs.h just has a bunch of:
|
|
|
|
#include "fileutils.h"
|
|
#include "shellutils.h"
|
|
|
|
which would then have smaller sets of #defines...
|
|
Hmm. Needs to be carefully thought out.

#1 You are storing by id instead of name like normal tar. Did you realize this?
|
|
(or am I missing some compile option? )ctar did not do this, and I don't think
|
|
it's a good idea for LRP.
|
|
|
|
#2
|
|
ctar did not produce the EOF error like your tar does. I believe you need to
|
|
pad the end of the archive with at least 2 tarsized (512byte) blocks. (I
|
|
think???)
|
|
|
|
#3
|
|
There is no exclude file(s) option to tar. LRP's packaging system can not
|
|
function without this. Will you have the time to add this soon?

mv * BACKUP
|
|
|
|
Today, "mv" behaved as a cp -a and my disk becomed full. It does not
|
|
work properly either when renaming a directory into something else
|
|
(it produces a lot of disk activity when doing this).

Feature request:
|
|
|
|
/bin/busybox --install -s which makes all links to commands that it
|
|
can support (an optionnal -s should be used for symbolic links instead
|
|
of hard links).

|
|
|

So far I had not considered it. Basically, you wish to have
|
|
messages from the embedded box logged to a remote network
|
|
syslog box, right? I can see that this would be useful.
|
|
I'll add this to the TODO list,
|
|
|
|
|
|
-----------------------
|
|
|
|
|
|
In utility.c:copyFile: It uses followLinks for both source and
|
|
destination files... is that right for `mv'? Will need to revisit
|
|
the GNU, freeBSD, and MINIX versions for this... Should read the
|
|
Unix98 and POSIX specs also.
|
|
|
|
-----------------------
|
|
|
|
I think that the add_inode &c in utility.c needs to also stow the
|
|
st_dev field, and that du.c should NOT call `reset_inode_list'
|
|
because there can be hard links from inside one argv/ to inside
|
|
another argv/. du.c probably ought to have an -x switch like GNU du
|
|
does also...

|
|
|
|
As a point of reference, here's a slightly tweaked analysis of the
|
|
programs on the system I'm reading your mail on. Basically, I ran the
|
|
following script...
|
|
|
|
Q> #!/bin/bash
|
|
Q> function use() {
|
|
Q> for Z in $* ; do
|
|
Q> strings $Z | grep /proc | sed "s=^=$Z ="
|
|
Q> done
|
|
Q> }
|
|
Q> use /{,s}bin/* /usr/{,s}bin/* | sort -u | tee proc-usage
|
|
|
|
...and then went through it removing comments and print format
|
|
strings. Replace /proc with /dev and you'd soon have an equivalent
|
|
list for that - although I can report that such is MUCH larger...
|
|
|
|
There are three programs therein that refer to /proc/mounts ...
|
|
|
|
/bin/mount
|
|
/bin/umount
|
|
/usr/bin/eject
|
|
|
|
...and, as you stated, none that refer to /proc/atm on this system.
|
|
However, as this is a RedHat Linux 5.0 based system, that's not
|
|
necessarily an up to date reference thereto...
|
|
|
|
Here's the list anyway...
