2006-01-09Bug 112, return value of awk should be /256. In reality, we should probablyRob Landley
be using WEXITSTATUS(), but until I can figure out why the heck that would want to do (*(int *) &(status)) on the value, I'm happy just fixing the bug we actually see.
2005-11-28fix bug #474:Paul Fox
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.

There is another problem with constructions like "print (A+B) ++C", I don't know whether somebody uses such constructions (fixing both these problems would require very serious change in awk code).
2005-05-18Patch from Colin Watson (mangled slightly by Rob Landley):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.
2005-05-18Doug Swarin pointed out a security bug in the -i option of sed.Rob Landley
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.

On machines with only ANSI compliant compilers, not explitily delcaring an empty parameter list 'void' causes failure.
2004-11-25Hiroshi found another bug. Currently sed's $ triggers at end of every file,Rob Landley
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
2004-10-30Hiroshi Ito found some bugs. The 'c' command (cut and paste) was hardwiredRob Landley
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. egor

add sed -r support. I bumped into a couple of things that want to use extended regular expressions in sed, and it really isn't that hard to add. Can't say I've extensively tested it, but it's small and isn't going to break anything that doesn't use it, so... Rob

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...
