2004-05-10Fix for debian bug #248106, should use int for returned getopt value.Glenn L McGrath

2004-04-21This sed patch can only be described as "duh". Stat the source file, chmodEric Andersen
the _destination_ file. (Ah hah! That works _much_ better...) I implemented the behavior, I just forgot to test this corner of it. My fault, sorry... No, gnu sed -i doesn't preverve ownership information. I checked. Permissions, yes, ownership info, no. Rob
2004-04-21So I'm building a linux from scratch system, using a working script to do thisEric Andersen
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? Rob

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! - Larry
2004-04-01The last patch broke:Rob Landley
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. root# cd /tmp root# cat 1.sh #!/bin/sh cd /tmp rm -f ipsec.conf ipsec.conf+ cat >ipsec.conf <<\EOF version 2.0 config setup klipsdebug=none plutodebug=none plutostderrlog=/dev/null conn %default keyingtries=1 ...

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.

2004-02-06Richard Kojedzinszky writes:Eric Andersen
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.

Hi, I've noticed the bug also, and here is another patch for it. I hope it'll not introduce more bugs. Not too nice, but works for me. Here it is for busybox-1.00-pre6

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.
2003-10-30Patch from Dmitry Zakharov,Glenn L McGrath
Fixes two bugs: - END block didn't execute after an exit() call - huge memory consumption and performance degradation on large input (now performance is comparable to gawk)

the busybox menuconfig triggered my "inacceptable number of spelling mistakes" upper level, so I decided to make a patch ;-) I also improved some wording to describe some things in a better way. Many thanks for an incredible piece of software! Andreas Mohr, random OSS developer

2003-10-04Patch from Rob Landley;Glenn L McGrath
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...)

2003-09-14Patch from Rob Landley Glenn L McGrath
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...)

Hello all, This patch adds more "Help" text to the config system. Almost all applets now have a help entry. Also, I cleaned up the spacing of the existing text so that things are consistent. This patch is against this morning's CVS. Thomas Cameron CEI Systems, Inc.
