2724fa9d8a remove alarm() calls which were functioning as a primitive
watchdog function, presumably to catch infinite loop bugs. 
(control-C can do the same thing, and the alarms were too short in
any case.)  also, switch to sigsetjmp/siglongjmp in order to allow
repeated use of control-C -- otherwise it works once, then not again.

35e9c5d83a fixups to vi usage, and move the initial redraw() past the
execution of commands supplied by -c or EXINIT, so their
effect is displayed correctly.

c51fc7bed6 fixed the "dot" (i.e. '.') command, to properly re-init its
buffer between commands, not recalculate its length all the time,
and to not reallocate its fixed-length buffer frequently.

fixed the 'c', 'd', and 'y' commands to properly handle both motions
that are just part of a line, and those that are multiline.  for
instance, now "c%" and "2cw" work correctly, whether the motions span
lines or not.

added some permissble motions for 'c', 'd', and 'y':  namely 'h',
'l', SPACE, BS, and DEL

eaabf0675f vi: multiple fixes by Natanael Copa <natanael.copa@gmail.com>
* the puzzling message on error is replaced with strerror(errno)
  so it should be even more detailed and smaller at the same time.
* merged code in edit_file() and code for ':edit <file>' in colon() into
  new func init_text_buffer(). Was horribly duplicate. Moved most of
  error/sanity checking to file_insert(). Result is that you get a proper
  validation (prevent reading /dev/*) and error messages for ':r <file>' 
* renamed 'cfn' to 'current_filename' for improved readability
* merged smallint vi_readonly and readonly into bitfields into
  readonly_mode to save space.
* added text_size variable to keep track how big the text buffer is.
  This is used to fix a buffer overflow. To reproduce bug:
  ./busybox vi TODO
  :r Makefile
  vi segfaults due to no buffer checking is done at all. som redesign is
  needed here but i added a check in text_hole_make() to aviod the
  segfault at least.
* removed isblnk() and use isblank(3) instead.
* fixed compiler warning by displaying the return code for :!<command>
  This makes things bigger than needed but since the patch reduces the
  overall size... (see below)
* new func next_tabstop(int) merges some duplicate code. There are more
  cuplicode here but i couldnt find a good way to merge them.
* Fix *ANNOYING* placement of cursor on '\t' characters. To reproduce:
    echo -e "\thello" > file1
    ./busybox vi file1
  Try to insert some text at the beginning of line. Text will be inserted
  but cursor is blinking somewhere else. The patch should make busybox vi
  behave more like original vi(m). Costs a few bytes but its worth it
  imho.
* new_text() is moved into init_text_buffer()
* the previously added update_ro_status() was moved info file_insert due
  to duplication removal mentioned above.

67b23e6043 getopt_ulflags -> getopt32.
It is impossible to formulate sane ABI based on
size of ulong because it can be 32-bit or 64-bit.
Basically it means that you cannot portably use
more that 32 option chars in one call anyway...
Make it explicit.

88621d7398 Svn 16007 broke the build under gcc 4.0.3. This fixes up some of the damage
(the e2fsprogs directory is too twisty and evil to easily fix, but I plan
to rewrite it anyway so I'll just bump that up in priority a bit).

d921b2ecc0 Remove bb_ prefixes from xfuncs.c (and a few other places), consolidate
things like xasprintf() into xfuncs.c, remove xprint_file_by_name() (it only
had one user), clean up lots of #includes...  General cleanup pass.  What I've
been doing for the last couple days.

And it conflicts!  I've removed httpd.c from this checkin due to somebody else
touching that file.  It builds for me.  I have to catch a bus.  (Now you know
why I'm looking forward to Mercurial.)

4795e4e011 Rich Filker spotted that sed -e 's/xxx/[/' didn't work right. Did a smaller
fix than his, and shrank the code a bit on top of that so the net size is

an xterm it's running in.  The vi signal behavior would catch and restarts lots
of signals, like SIGHUP, that should just kill the thing.  (Leftover behavior
from when it would segfault all the time.)  Filtered out the more obviously
bad ones.  If it segfaults, we should find and fix the problem.

problem was that the buffer used for "." command ("last_modifying_cmd")

over the front of that buffer when a repeatable insert command
included backspacing (e.g. "i\b\b\bfoo").  the fix is to simply
record the backspaces along with the rest of the command.
    
also, cleaned up start_new_cmd_q() slightly.

on small screens.

with this change a) the status line should always be refreshed
properly, b) the status line is a little shorter than it used to
be ("I" instead of "--INSERT--"), c) the status line will be
truncated if it doesn't fit on the screen, and d) if the screen
is too narrow for an error or transient status message (from
psb() or psbs()), then that message will be followed by a "Hit
Return" prompt.  (it wasn't until i did this last bit that the
size grew.  with this, these changes add about 150 bytes.)

93850a56b2 Patch from Colin Watson (mangled slightly by Rob Landley):
This patch implements the 'T' command in sed. This is a GNU extension,
but one of the udev hotplug scripts uses it, so I need it in busybox
anyway.

Includes a test; 'svn add testsuite/sed/sed-branch-conditional-inverted'

5797c7f0ef Doug Swarin pointed out a security bug in the -i option of sed.
While the permissions on the temp file are correct to prevent it from being 
maliciously mangled by passing strangers, (created with 600, opened O_EXCL, 
etc), the permissions on the _directory_ might not be, and we re-open the 
file to convert the filehandle to a FILE * (and automatically get an error 
message and exit if the directory's read-only or out of space or some such).

This opens a potential race condition if somebody's using dnotify on the 
directory, deletes/renames the tempfile, and drops a symlink or something 
there.  Somebody running sed -i as root in a world writeable directory could 
do damage.

I dug up notes on an earlier discussion where we looked at the security 
implications of this (unfortunately on the #uclibc channel rather than email; 
I don't have a transcript, just notes-to-self) which pointed out that if the 
permissions on the directory allow other people's files to be deleted/renamed 
then the original file is vulnerable to sabotage anyway.  However, there are 
two cases that discussion apparently didn't take into account:

1) Using another user's permissions to damage files in other directories you 
can't access (standard symlink attack).

2) Reading data another user couldn't otherwise access by having the new file 
belong to that other user.

This patch uses fdopen to convert the filehandle into a FILE *, rather than
reopening the file.

dcc286607c Hiroshi found another bug. Currently sed's $ triggers at end of every file,
and with multiple files SuSv3 says it should only trigger at the end of the
LAST file.

The trivial fix I tried first broke if the last file is empty.  Fixing this
properly required restructuring things to create a file list (actually a
FILE * list), and then processing it all in one go.  (There's probably a
smaller way to do this, merging with append_list perhaps.  But let's get
the behavior correct first.)

Note that editing files in place (-i) needs the _old_ behavior, with $
triggering at the end of each file.

Here's a test of all the things this patch fixed.  gnu and busybox seds produce
the same results with this patch, and different without it.

echo -n -e "1one\n1two\n1three" > ../test1
echo -n > ../test2
echo -e "3one\n3two\n3three" > ../test3
sed -n "$ p" ../test1 ../test2 ../test3

ce4f0e982b Hiroshi Ito found some bugs. The 'c' command (cut and paste) was hardwired
to not put a newline at the end (which was backwards, it should have been
hardwired _to_ put a newline at the end, whether or not the input line
ended with a newline).  Test case for that:

echo | sed -e '$ctest'

And then this would segfault:

echo | sed -e 'g'

Because pattern_space got freed but the dead pointer was only overwritten
in an if statement that didn't trigger if the hold space was empty.  Oops.

While debugging it, I found out that the hold space is persistent between
multiple input files, so I promoted it to a global and added it to the
memory cleanup.  The relevant test case (to compare with That Other Sed) is:

echo -n woo > woo
sed -e h -e g woo
echo "fish" | sed -e '/woo/h' -e "izap" -e 's/woo/thingy/' -e '/fish/g' woo -

And somebody gratuitously stuck in a c99 int8_t type for something that's just
a flag, so I grouped the darn ints.

Hi!

I've created a patch to busybox' build system to allow building it in
separate tree in a manner similar to kbuild from kernel version 2.6.

That is, one runs command like
'make O=/build/some/where/for/specific/target/and/options'
and everything is built in this exact directory, provided that it exists.

I understand that applyingc such invasive changes during 'release
candidates' stage of development is at best unwise. So, i'm currently
asking for comments about this patch, starting from whether such thing
is needed at all to whether it coded properly.

'make check' should work now, and one make creates Makefile in build
directory, so one can run 'make' in build directory after that.

One possible caveat is that if we build in some directory other than
source one, the source directory should be 'distclean'ed first.
