0000054: Tab completing filenames in ash causes SEGV
Simple tab completion operations cause busybox (ash) to
access illegal addresses.

Thanks!

This is a bulk spelling fix patch against busybox-1.00-pre10.
If anyone gets a corrupted copy (and cares), let me know and
I will make alternate arrangements.
Erik - please apply.
Authors - please check that I didn't corrupt any meaning.
Package importers - see if any of these changes should be
passed to the upstream authors.
I glossed over lots of sloppy capitalizations, missing apostrophes,
mixed American/British spellings, and German-style compound words.
What is "pretect redefined for test" in cmdedit.c?
Good luck on the 1.00 release!

- declare applet_using as static from applets.c
- small correction to cmdedit,
previous version cleared history after Ctrl-C
- small spelling correction (by Friedrich Lobenstock)
|
|
- synced with dash 0.4.21
- better handle trap "cmds..." SIGINT (strange, i make bad hack for ash
and cmdedit, but this work only with this...)
- may be haven`t problem with Ctrl-D

to ensure proper fallback behavior on, i.e. serial consoles.

Last patch have synced form Manuel Nova III xxreadtoken() function,
corrected (C) form dash debian/copyright, removed my small mistake
with IFS_BROKEN (thanks by Herbert), and synced cmdedit.c from
current CVS (removed libc5 support, your email correction, my (C) year
corertion).

config system
- added a new config option to allow persistant history lists. This is
currently only used by ash, but the calls ({load,save}_history) could
be added to the other shells as well.

HP iPAQ. Sometimes we get a SIGWINCH and want to print the prompt, although
the prompt is not yet initialised (0) .. so just don't print a prompt
as long as the prompt string is 0

#49: I found one memory overflow and memory leak in "ln" applet.
Last patch reduced also 54 bytes. ;)
#50: I found bug in loginutils/Makefile.in.
New patch have also new function to libbb and
aplied this to applets and other cosmetic changes.

math suport, cleaner math syntax error checking, moves redundant signal
string tables (from kill and ash) into libbb and provides a few
cleanups elsewhere.
|
|
|

1) ping cleanup (compile fix from this patch already applied).
2) traceroute call not spare ntohl() now (and reduce size);
3) Fix for functions not declared static in insmod, ash, vi and mount.
4) a more simple API cmdedit :))
5) adds "stopped jobs" warning to ash on Ctrl-D and fixes "ignoreeof" option
6) reduce exporting library function index->strchr (traceroute), bzero->memset (syslogd)

Changed email address
cmdedit API change
optimizations for traceroute and md5sum
added a new shared create_icmp_socket() function

which seems to not solve the problem I thought it solved.

signal handling in cmdedit.c. Disabling it makes the shells behave
themselves again. hush isn't quite there, but is getting close...

xgetcwd, but did not check the return for a NULL, and then continued
to call strlen on the NULL when the cwd had been removed from under it.

'ls *.h Config.h' works. Fixed a silly typo with fg/bg process control.
Made cmdedit exit sanely when it cannot read input.
