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.

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
sed -n "$ p" ../test1 ../test2
sed -i -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.

I bumped into a couple of things that want to use extended regular expressions

tested it, but it's small and isn't going to break anything that doesn't use
it, so...

b94669543d This sed patch can only be described as "duh". Stat the source file, chmod

faa7d863fc So I'm building a linux from scratch system, using a working script to do this
that the _only_ change to is that gnu sed has been replaced with busybox sed.
And ncurses' install phase hangs.  I trace it down, and it's trying to run
gawk.  (Insert obligatory doubletake, but this is FSF code we're talking
about, so...)

It turns out gawk shells out to sed, ala "sed -f /tmp/blah file.h".  The
/tmp/blah file is basically empty (it contains one character, a newline).  So
basically, gawk is using sed as "cat".  With gnu sed, it works like cat,
anyway.

With busybox sed, it tests if its command list is empty after parsing the
command line, and if the list is empty it takes the first file argument as a
sed command string, and if that leaves the file list empty it tries to read
the data to operate on from stdin.  (Hence the hang, since nothing's coming
in on stdin...)

It _should_ be testing whether there were any instances of -f or -e, not
whether it actually got any commands.  Using sed as cat may be kind of
stupid, but it's valid and gawk relies on this behavior.

Here's a patch to fix it, turning a couple of ints into chars in hopes of
saving a bit of the space this adds.  Comments?

25d82397f7 The last patch broke:
sed -i "/^boo/a fred" ipsec.conf

Which works in gnu sed.  (And is _supposed_ to strip all the whitespace before
"fred".)

It also broke:
sed -i -e "/^boo/a \\" -e "   fred" ipsec.conf

I.E. there can legally be spaces between the a and the backslash at the end of
the line.

And strangely enough, gnu sed accepts the following syntax as well:
sed -i "/^boo/a \\  fred" ipsec.conf

Which is a way of having the significant whitespace at the start of the line,
all on one line.  (But notice that the whitespace BEFORE the slash is still
stripped, as is the slash itself.  And notice that the naieve placement of
"\n" there doesn't work, it puts an n at the start of the appended line.  The
double slashing is for shell escapes because you could escape the quote, you
see.  It's turned into a single backslash.  But \n there is _not_ turned into
a newline by the shell.  So there.)

This makes all three syntaxes work in my tests.  I should probably start
writing better documentation at some point.  I posted my current sedtests.py
file to the list, which needs a lot more tests added as well...

The sed command in busybox 1.0.0-pre8 loses leading whitespace

=== reproduction recipe ends here ===

This problem was introduced in 1.0.0-pre4.  The problem is that
the command argument parsing code strips leading whitespaces too
aggressively.  When running the above example, the piece of code
in question gets "\n\tnat_traversal=yes" as its argument in
cmdstr variable (shown part in the following patch).  What it
needs to do at this point is to strip the first newline and
nothing else, but it instead strips all the leading whitespaces
at the beginning of the string, thus losing the tab character.
The following patch fixes this.

While building glibc with busybox as part of the development environment, I
found a bug in glibc's regexec can throw sed into an endless loop.  This
fixes it.  Should I put an #ifdef around it or something?  (Note, this patch
also contains the "this is not gnu sed 4.0" hack I posted earlier, which is
also needed to build glibc...)

sed is broken:

 busybox sed -n '/^a/,/^a/p' >output <<EOF
 a
 b
 a
 b
 EOF
 cmp -s output - <<EOF
 a
 b
 a
 EOF

The attached patch fixes it.

42c25735e6 Patch from Rob Landley;
Moving on to building diffutils, busybox sed needs this patch to get
past the first problem.  (Passing it a multi-line command line argument
with -e works, but if you don't use -e it doesn't break up the multiple
lines...)
