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:
|
|
|
|
- mkfs.minix rev 1.7 completely broke the parser. Fix it.
|
|
- '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
|
|
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.
|
|
- Make 'mount -a' work even when /proc isn't mounted (ugly bug).
|
|
- Make 'ln -s /tmp/file .' work the way GNU ln does (i.e. makes a link to
|
|
/tmp/file in the current directory, rather then trying and failing to create
|
|
a symlink named "." in the current working directory).
|
|
- implement 'ls -R'.
|
|
- "cp -a sourcedir/*" (note: no dest) - produces an odd error message about
|
|
the last file in the dir, rather than saying "missing destination file".
|
|
|
|
|
|
-----------
|
|
|
|
* Make insmod actually work
|
|
* dnsdomainname
|
|
* traceroute/netstat
|
|
* rdate
|
|
* hwclock
|
|
* stty
|
|
* expr
|
|
* wget (or whatever I call it)
|
|
* tftp
|
|
* ftp
|
|
* group/commonize strings, remove dups (for i18n, l10n)
|
|
|
|
|
|
-----------------------
|
|
|
|
Running 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, 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...)
|
|
|
|
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.
|
|
|
|
To be replaced with a busybox local glob routine:
|
|
|
|
[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?
|
|
|
|
|
|
-----------------------
|
|
|
|
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.
|
|
|
|
Perhaps I need to add a better build system (like the Linux kernel?)
|
|
|
|
-----------------------
|
|
|
|
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...
