Which sys-apps/findutils version is this about?

Hrm. Works here. What's the output of 'ls -ld /'?

Hi there,

i'm in same situation.

find version[ 4.1.20 ], works good, but
find version[ 4.2.27 ], no results...
  
  
  $ find --version
  GNU find version 4.2.27
  Features enabled: D_TYPE O_NOFOLLOW(enabled) LEAF_OPTIMISATION
  
  
  $ mkdir work_20051208 && cd work_20051208
  $ touch file .hidden_file && mkdir -p dir_L1/dir_L2
  
  
  $ tree -aF
  .
  |-- .hidden_file
  |-- dir_L1/
  |   `-- dir_L2/
  `-- file
  
  
this operation looks good at both version.
  $ find ./
  ./
  ./file
  ./dir_L1
  ./dir_L1/dir_L2
  ./.hidden_file
  
  
these operation no results at version[ 4.2.27 ]::
  $ find ./ -regex '.*'  
  $ find ./ -regex "./file"
  $ find ./ -regex './file'
  $ find ./ -regex '\.\/file'
  
  
i see man page and found the new option[ regextype ].
but, not find any {file,directory} on using option[ regex ] at version[ 4.2.27 ]
  find ./ -regextype  findutils-default   -regex '.*'

...well, i use wrong option or something?

I think the problem is related to '--without-included-regex' option of
./configure. Compiling findutils without this flag seems to fix the problem.
Could this be a glibc problem?
My glibc version is 2.3.6-r1

So if you take the --without-included-regex out of the ebuild, change nothing
else and reinstall, it works?

for the reference,
I tried re-install sys-apps/findutils as downgrade FROM 4.2.27 TO 4.2.25.
                                                            ^^        ^^
and works fine even enable configure option[ --without-included-regex ].

the configure option is:
  ./configure                 \
    --prefix=/usr             \
    --host=i686-pc-linux-gnu  \
    --mandir=/usr/share/man   \
    --infodir=/usr/share/info \
    --datadir=/usr/share      \
    --sysconfdir=/etc         \
    --localstatedir=/var/lib  \
    --enable-nls              \
    --without-included-regex  \
    --build=i686-pc-linux-gnu

which as same as version[ 4.2.27 ].


on version[ 4.2.25 ], works good. :)
what the difference these versions...

What I need to know is whether, with *4.2.27*, removing the
--without-included-regex removes the problem for those who are seeing it. If
there's an issue with findutils, there will probably be an issue with grep etc
when we put out the next version with --without-included-regex too.

I confirm that removing --without-included-regex from the ebuild and reemerging 
findutils makes it work. 

Ok, could you try adding --without-included-regex to the grep and sed ebuilds
and see if they break in the same way? You'll probably want to make a quickpkg
beforehand...

I think I have an explanation:  
even if --without-included-regex is defined, -I../gnulib/lib is still present 
in the compilation command. As a result, ../gnulib/lib/regex.h is included 
instead of /usr/include/regex.h. The problem is that the 2 declarations of 
re_match doesn't match: 
extern regoff_t re_match (struct re_pattern_buffer *__buffer, 
			  const char *__string, __re_idx_t __length, 
			  __re_idx_t __start, struct re_registers *__regs); 
for ../gnulib/lib/regex.h 
extern int re_match 
  _RE_ARGS ((struct re_pattern_buffer *buffer, const char *string, 
             int length, int start, struct re_registers *regs)); 
for /usr/include/regex.h 
On my system, regoff_t is a typedef of __off64_t, a 64bits integer. When 
compiling, gcc expects re_match to return a 64 bits integer (split in %eax and 
%edx), but glibc version of re_match returns the result only in %eax (since for 
glibc version result is 32 bit), and there could be anything in %edx, which is  
nevertheless used to test the result sign when comparing re_match return value 
with matched string length... 

hmm, a plausible idea ... i have been testing on 64bit systems ...

can you try running the emerge again, but this time, after the ebuild
finishes unpacking, delete that header file and in the gnulib subdir

As expected, deleting regex.h from the gnulib subdir solves the problem. 

awesome, thanks for tracking that down ... cant say i would have ever thought
of looking there

Could you try 4.3.0? There's a rather nasty 'fix' included in the ebuild which
might work. Or it might not...

great 4.3.0! works very fine!
thanks all

  $ find --version
  GNU find version 4.3.0
  Features enabled: D_TYPE O_NOFOLLOW(enabled) LEAF_OPTIMISATION FTS
                                                                 ^^^

Ok, looks like this is fixed. Please reopen if anyone's still affected.

Please apply the same fix to the 4.2.27 ebuild.
(It works here: with it, 4.2.27 now passes its tests.)

why

last time i checked, 4.3.0 > 4.2.27

Because I thought it likely that 4.2.27 would reach stable before 4.3.0, as the
latter one is marked as a development version by upstream.

Nnnnope.

If 4.2.27 is not going to get fixed, then please hard-mask it, as it is broken
(for some).

No. Every findutils is broken in some way. If we were to mask every version
that had some minor bug then there wouldn't be any available at all.

But this is not a minor bug, and it is one not present in 4.2.25 and 4.3.0
(now).

Also, this bug is about 4.2.27, and it is marked as fixed, but it is not fixed:
it is just superseded by a newer version.
