| 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: |
| |
| - '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). |
| |
| ----------------------- |
| |
| |

| > would quite make sense on embedded systems... :) |
| |
| 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... |
