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).
* Networking apps are probably going to be split out some time soon into a
separate package (named perhaps netkit-tiny?). This would remove the
following items from BusyBox: hostid, hostname, nc, nslookup, telnet,
and ping. nfs mounting and syslogd (when it supports network logging)
will remain in BusyBox.

Bugs that need fixing:
2000-05-09 04:55:59 +05:30
- 'grep foo$ file' doesn't work
- 'grep *foo file' segfaults
- ps dirent race bug (need to stat the file before attempting chdir)
- The following commands segfault:
chmod -R
chown -R
chgrp -R
cp -a -a
ln -s -s
rm -f
2000-06-01 01:38:30 +05:30
rm -f -
rm -- -
touch -c
- I believe that swaponoff may also be also broken (check it).
- It used to be that BusyBox tar would happily overwrite existing files on
an extraction. However, as of 0.42, BusyBox tar simply dies as soon as an
existing file is found.

-----------------------
Running the following:
2000-05-02 01:20:37 +05:30
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, and
then create a microLibc to provide these functions. There is no good reason
for GNU libc to be so big. I'm sure it can be a lot better.
(BTW, this is more informative if BB_FEATURE_NFSMOUNT is turned off...)
2000-05-02 05:37:56 +05:30
Most wanted list:
[andersen@slag busybox]$ grep -l getgroups *.[ch]
test.c
Policy violation. getgroups uses libc nss, which is unlikely
to be present in an embedded system.
2000-05-14 00:38:58 +05:30
To be replaced with a busybox local glob routine:
2000-05-02 05:37:56 +05:30
[andersen@slag busybox]$ grep -l glob *.[ch]
gunzip.c
gzip.c
sh.c
tar.c
telnet.c
Can check_wildcard_match() from utility.c do this job?
2000-03-01 03:19:22 +05:30
-----------------------
Compile with debugging on, run 'nm --size-sort ./busybox'
and then start with the biggest things and make them smaller...
2000-02-19 03:04:17 +05:30
-----------------------
busybox.defs.h is too big and hard to follow.
Perhaps I need to add a better build system (like the Linux kernel?)
2000-02-19 03:04:17 +05:30
-----------------------
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,
-----------------------
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...
