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.

following items from BusyBox: hostid, hostname, nc, nslookup, telnet,
and ping. nfs mounting and syslogd (when it supports network logging)
will remain in BusyBox.

Added some bugs / TODOs.

Note that I broke mkfs_minix's parser in rev 1.7. -Erik
2000-06-03 05:57:00 +05:30
- mkfs.minix rev 1.7 completely broke the parser. Fix it.

Note how to find list of BusyBox libc dependancies, the ide being to limit them much more. -Erik
2000-05-02 00:57:17 +05:30
-----------------------
Running the following:
Minor doc change
2000-05-02 01:20:37 +05:30

2000-05-02 00:57:17 +05:30
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.
My little adventure of analyzing lib usage has already rooted out a big "P" Policy violator -- logname was using getlogin(3), which uses utmp under the hood. We don't need no stinkin' utmp (and if we are using tinylogin, it is unlikely to be useful trying). -Erik
2000-05-02 01:19:20 +05:30
(BTW, this is more informative if BB_FEATURE_NFSMOUNT is turned off...)
More stuff -Erik
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.
TODO update -Erik
2000-05-14 00:38:58 +05:30
To be replaced with a busybox local glob routine:
More stuff -Erik
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?

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.
Tar now works perfectly. It behaves much better now then it used to. Only thing left to do is add in exclude (-X) option. -Erik
2000-04-05 06:30:52 +05:30
Perhaps I need to add a better build system (like the Linux kernel?)
Some updates for the day, -Erik
2000-02-19 03:04:17 +05:30
-----------------------
Fixed du. Now behaves just like GNU du (only less so). -Erik
2000-02-19 23:46:49 +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).
Add in a TODO item, -Erik
2000-02-22 22:42:00 +05:30
-----------------------

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,
A few updates (including the cp fix the Craig has been looking for) -Erik
2000-03-05 02:49:32 +05:30
-----------------------
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...
My latest ramblings. -Erik

An interesting email listing some apps that use /proc. BusyBox
tries to avoid /proc as mush as is possible, so this stuff is
interesting (to me at least):

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...
