Subject: grep -vw segfault on word matches in UTF-8 locales

Date: Mon, 27 Aug 2007 20:51:23 +0200

Package: grep
Version: 2.5.3~dfsg-1
Severity: normal
File: /bin/grep

        Hi,

 % echo -foo | grep -vw foo
 zsh: done                echo -foo | 
 zsh: segmentation fault  grep --color=auto -vw foo

(gdb) bt
#0  0xb7ea2269 in memchr () from /lib/i686/cmov/libc.so.6
#1  0x0804ab43 in ?? ()
#2  0x00000001 in ?? ()
#3  0x0000000a in ?? ()
#4  0x08064001 in ?? ()
#5  0x08064006 in ?? ()

 Seems to happen in fr_FR.UTF-8 and en_US.UTF-8, but not in C locale.

 After I rebuilt with DEB_BUILD_OPTIONS="nostrip noopt", I got:
(gdb) bt
#0  0xb7e21269 in memchr () from /lib/i686/cmov/libc.so.6
#1  0x0804ab43 in prtext ()
#2  0x0804ae0c in grepbuf ()
#3  0x0804b79b in grepfile ()
#4  0x0804d6c7 in main ()

 I don't have any more context available, I hope you can reproduce the
 bug.

   Bye,

Hello Loïc,

I didn't get a segfault when I run neither 'echo -foo | grep --color=auto -vw foo'
nor 'echo -foo | grep -vw foo'.

When I run 'echo -foo bar | grep --color=auto -w foo -foo bar', I get:

-foo bar

with "foo" coloured red.

$ dpkg -l grep libc6 | grep ^ii
ii  grep           2.5.3~dfsg-1   GNU grep, egrep and fgrep
ii  libc6          2.6.1-1+b1     GNU C Library: Shared libraries

The --color wasn't necessary.   Loïc apparently has grep aliased or
GREP_OPTIONS set?

> $ locale

What about LANG=en_AU.UTF8?

$ echo -foo |LC_ALL=en_AU ./tmp/grep.unstable -vw foo
$ echo -foo |LC_ALL=en_AU.UTF8 ./tmp/grep.unstable -vw
foo
Segmentation fault

I just re-confirmed the reported misbehavior of the rest of these grep
bugs too.

  You're playing with everyone's nerves are you ? Don't you grok that
you are not reproducing the bug in the environment reported by every
single users ? It's pretty obvious the issue is with utf-8 locales, and
you're trying in one that isn't even a multi-byte one.


  I was pretty dismayed when you sent me a similar answer, I just can't
believe that you just handwave a "I can't reproduce it" to every single
user that has issues with the last grep release. Do you believe everyone
is just making it up to annoy you ?

please let us know.

It does not seem to fix the problem:
I installed you package, and tried examples given in bugs 439827, 440195, and 
440342, and they all failed.

my locale is 
Locale: LANG=fr_FR.UTF-8, LC_CTYPE=fr_FR.UTF-8 (charmap=UTF-8)

Hi,

Uploaded another version. Sorry, in my running I didn't build correctly 
the package and forgot to upload the source.

$ echo -foo | grep -vw foo

Oups, looks like it does not work so well.
with your latest version, -w is fixed, but now, -i is broken:

$ echo word > file
$ echo Word >> file
$ grep -i word file
word

Subject: Patch 65-dfa-optional.patch causes grep regressions

Date: Wed, 5 Sep 2007 21:23:32 +0200

tags 439827 patch
tags 439827 -upstream
thanks

Hello,

The regressions in grep 2.5.3~dfsg-1 are caused by patch
65-dfa-optional.patch.

It should be removed.

As it was used in combination to 64-egf-speedup.patch (which was already
removed) to speed up grep in UTF-8 environments, the resulting grep should
be slow again (#181378 is back)

I will try to have a look at whether these two patches can be re-introduced
next week or later.

By that time, I recommend to remove patch 65-dfa-optional.patch.

Best Regards,

(I don't understand why you un-confirm 439931; it looks like a valid and
reproducible bug to me)

> Hello, did you see #439931 too?

I did not check, but I guess that re-adding the old 64-egf-speedup.patch
should fix it.

Also patches 66-match_icase.patch and 67-w.patch should be considered.

These patches tend to be quite long and hard to maintain. I did not check
if they apply cleanly or not, or even if they were already applied
upstream (based on the result of the test suite, I'm just guessing that
they may still be needed).

Kind Regards,

I thought that it was specific to amd64, and don't have ready access
to a "pure" 64 bit system on which to check.
