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?

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!

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
in 'a' command ('i' and 'c' commands are also affected).  A
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 ===
* Part 1.  Use busybox 1.0.0-pre3 as sed; this works.

  as sed; this fails.

=== 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.

Hi All,

I aplogoize for the mistake, but i have just recognized that somehow the
last patch I sent in was wrong, and a '0' was instead of a '-1'. Because
of this, vi does behave the wrong way. So again, it should be the last
patch for vi. This is for pre7.

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...)

85208e2ab9 Completely rework the config system so that it no longer annoys me to work on
the busybox development tree.  This eliminates the use of recursive make, and
once again allows us to run 'make' in a subdirectory with the expected result.
And things are now much faster too.  Greatly improved IMHO...

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

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.

bf181b9338 Extract usage information into a separate file. 2000-07-16 20:57:15 +00:00
Mark Whitley
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.
2000-07-14 23:24:00 +00:00

70705d7c96 - Added support for semicolon delimited command lines. (woo-hoo!)

 - 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.

06f3529ada Minor code reorg: Changed the interface to index_of_next_unescaped_slash to an
interface that seems a little more sensible to me. Also broke out s///
expression parsing into it's own subroutine.

c41e8c840f Changed bb_regcomp to xregcomp and #if 0'ed out destroy_cmd_strs in sed.c
(maybe I'll remove it later).

858c1adf2b Applied patch from Matt Kraai to call destroy_cmd_strs in atexit(), rather
than peppering it throughout the code.

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.

Tested under both libc5 and libc6 and all seems well with these fixes.

7ab9c7ee52 Lots of updates. Finished implementing BB_FEATURE_TRIVIAL_HELP
which lets you compile out most of the "--help" output, saving
up to 17k.

Renamed mnc to nc.

would go into an infinite loop.
