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).

0000474: vi crashes often

problem was that the buffer used for "." command ("last_modifying_cmd")
wasn't being maintined correctly -- the recording code was walking back
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.

8552aec7fd some combinations of status line and screen refresh don't give a
correct screen, and bug 215 reports trouble with the status line
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.)

Here's a fix for this. There is another problem with constructions like

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'
after applying.

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

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.

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

patch to fix this is attached at the end of this message.

The following is a transcript that reproduces the problem.  The
first run uses busybox 1.0.0-pre3 as "/bin/sed" command, which
gets the expected result.  Later in the test, /bin/sed symlink
is changed to point at busybox 1.0.0-pre8 and the test script is
run again, which shows the failure.

=== 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.

8aac05bfe5 Patch from Rob Landley
Fixed a memory leak in add_cmd/add_cmd_str by moving the allocation
of sed_cmd down to where it's actually first needed.
                                                                                
In get_address, if index_of_next_unescaped_regexp_delim ever failed, we
wouldn't notice because the return value was added to idx, which was 
already guaranteed to be > 0.  (This is buried in the changes made when 
I redid get_address to be based on pointer arithmetic, because all the tests 
were gratuitously dereferencing with a constant zero, which wasn't obvious.)
         
Comment in parse_regex_delim was wrong: 's' and 'y' both call it.
 
The reason "sed_cmd->num_backrefs = 0;" isn't needed is that sed_cmd was
allocated with cmalloc, which zeroes memory.

Different handling of space after \ in i...

Different handling of pattern "s/a/b s/c/d"

Cool, resursive reads don't cause a crash. :)

Fixed "sed -f blah filename - < filename" since GNU sed was handling 
both - and filenames on the same line.  (You can even list - more than 
once, although it's immediate EOF...)

c9f20d9fb9 Yet another major rework of the BusyBox config system, using the considerably
modified Kbuild system I put into uClibc.  With this, there should be no more
need to modify Rules.mak since I've moved all the interesting options into the
config system.  I think I've got everything updated, but you never know, I may
have made some mistakes, so watch closely.

822c3837f9 Another vi update from Sterling Huxley:
- All of the ESC sequences are now in variables.  This should make
  re-targeting for other terminals easier.

- The initial screen draw does not force out every single column.
  Should be faster.

- The place_cursor() routine trys to be smarter about moving the
  cursor.  This is optional based on BB_FEATURE_VI_OPTIMIZE_CURSOR.

- The 't' and 'f' intra-line positioning commands were added.
  They can now be used as targets in 'c' and 'd' commands, i.e.,
   dfx - delete from dot to next 'x'
   dtx - delete from dot to the char before next 'x'

- show_status_line() uses a static int checksum to remember what
  is currently displayed on the screen and not re-draw the status
  line unless it has changed.

- Some of the code in refresh() was moved out to format_line().
  refresh() trys to send out the smallest segment containing
  the changed chars rather than the whole line.

- Added "flash" to the :set command to specify if error indication
  should be by flashing the screen or ringing the bell.

- Changed the rawmode() routine so that it turns off the
  NL -> CR NL translation. On output of a NL, the OS will not add
  a CR.

- If vi was started as "view", with global read-only mode,
  and another file is opened, the file is opened read-only
  rather than read+write.

1f45b268cb As per a discussion on the mailing list between Matt and Pavel. I have removed
the -V (version) flag from busybox sed. It is unnecessary because sed is not a
standalone and should therefore be independently reporting a version number.
Moreover, it is extra code that we just don't need.

97562bd9d7 - Added support for backreferences in substitution expressions up to nine
(\1, \2...\9). This touched a lot of places in this file and I added a new
   function 'print_subst_w_backrefs' in order to keep 'do_subst_command' a
   little more tidy.

	* I tested this good 'n hard, but will always appreciate more testing from
	  other, willing folks.

 - Noticed that the index_of_next_unescaped_slash was subtly wrong so I
   changed both the functionality and behavior (it used to skip over the first
   char in the string you passed it, assuming it was a leading '/'--this
   assumption is no longer made) this necessitated changing the lines that
   call this function just slightly.

464c5de00d Fixed a couple of buglets:
- add_cmd_str: segv's were being generated if there was a '# comment' line
   (and probably other kinds of lines, too) that was not followed by a
   semi-colon or whitespace
 - parse_edit_cmd: was returning a wrong number (too low) for the index; it
   was not accounting for backslashes eaten, for the fact that we start at the
   3rd index in the string, or for the fact that we add an extra newline.
 - parse_cmd_str: was returning a wrong number (again, too low) for the index
   in the case of single-letter commands (p,d). There was some
   over-compensation for this in the 'return' stmt at the end which also
   needed some help.
 - load_cmd_file: was not eating trailing newlines off the line read from the
   command file. This had the deleterious effect of printing an extra newlines
   after text displayed from edit (i,a,c) commands.

70705d7c96 - Added support for semicolon delimited command lines. (woo-hoo!)
- Obsoleted the trim_str function (#if 0'ed out -- maybedelete later) in
   favor of strrspn.
 - Obsoleted the strrspn function (#if 0'ed out as well) as soon as I
   discovered that it wasn't needed either.
 - Fixed a subtle bug in parse_subst_cmd where it would choke with an error if
   there was any trailing space after the s/match/replace/ expression.

34623db618 It dawned on me that I would need to grow a char buffer one extra char bigger
to accomodate a trailing '\n'ewline that I append to it later one. This is
only necessary for the case of one inserted, appended, or changed line, but
it's still necessary.

df5f6ba115 Applied patch from Matt Kraai which does the following:
- adds case-insensitive matching in sed s/// epxressions
 - consolodates common regcomp code in grep & sed into bb_regcomp and put in
   utility.c
 - cleans up a bunch of cruft

6315ce603b Brand, new sed that uses libc regex routines.
There is some common code used by both sed & grep that should be put into
utility.c as per Mat Kraai's suggestions/patch on the mailing list.
Specifically, a common regex_compile() and a regex_subst() function need to be
made.

1266a13e1f * sed now supports addresses (numeric or regexp, with negation) and
has an append command, thanks to Marco Pantaleoni <panta@prosa.it>
* Fixed dmesg.  It wasn't parsing its options (-n or -s) properly.
* Some cosmetic fixes to ls output formatting to make it behave more
    like GNU ls.
