Comment 1 Martin Schlemmer (RETIRED) gentoo-dev 2005-08-15 05:46:41 UTC 
Please try again with sys-apps/sandbox-1.2.12 .. if not fixed, please reopen.
Comment 2 Michael Kiermaier 2005-08-24 13:31:25 UTC 
Same problem with sys-apps/sandbox-1.2.12, sorry.
Comment 3 Martin Schlemmer (RETIRED) gentoo-dev 2005-09-21 01:07:48 UTC 
Ugh, just update the kernel to something after 2.4.28 I think.  Earlier 2.4 
kernels have an issue with getcwd().
Comment 4 Art Wallace 2005-11-11 13:24:29 UTC 
I'm using Gentoo on an embedded PPC NAS and can't update my kernel because 
it's hardwired in flash RAM. I don't think something as simple as an update to 
TAR should cause such problems for my box. There must be some solution besides 
upgrading the kernel?

Comment 6 Art Wallace 2005-11-11 15:14:04 UTC 
great
Comment 7 Art Wallace 2005-11-11 15:16:04 UTC 
Martin Schlemmer, are you maintaining this ebuild or are you just trying to be 
helpful?
Comment 8 Martin Schlemmer (RETIRED) gentoo-dev 2005-11-11 15:44:38 UTC 
I maintain sandbox.  The issue is a difficult one, and the 'solution' do not
always seem to work.  That with the fact that all developers + most users
running sandbox during merges should give us fairly great confedence that you
using stable ppc profile should not have issues of packages installing files
directly into /.

Err, so basically if I did not ramble too much, you should not expect any issues
with disabling sandbox if you cannot update your kernel ... if then at least
only for tar.
Comment 9 Art Wallace 2005-11-11 16:05:07 UTC 
OK. If it's of any help to you, this issue only shows up for me with the bzip2 
flag enabled.
Comment 10 Martin Schlemmer (RETIRED) gentoo-dev 2005-11-11 16:34:51 UTC 
Created attachment 72718 [details, diff]
sandbox-getcwd-debug.patch

No, its OK, know fairly what the issue is.  If you can however add this to the
sandbox-1.2.12 ebuild, and remerge sandbox, then merge tar with the setup that
will make it fail, and include getcwd.log in $S, it might help.
Comment 11 Art Wallace 2005-11-12 09:19:18 UTC 
That patch won't work for me. It tries to create the log file inside the 
massive "confdir3/confdir3/confdir3/confdir3" path. If the log file exists, I 
can't seem to access it. It looks to be hundreds of directories deep and no 
program that I tried could get to it. I'm not even sure if the log file is 
actually created.

Can you tell it to save the log file in a fixed path?
Comment 12 Martin Schlemmer (RETIRED) gentoo-dev 2005-11-12 10:09:49 UTC 
Err, yeah sorry, missed that .. Just edit the patch, and change the "getcwd.log"
to say "/tmp/getcwd.log"
Comment 13 Art Wallace 2005-11-12 14:29:27 UTC 
I get this in the log:
errno = 2, tmpbuf = 0x7fff8530
Using __egetcwd()
errno = 2, tmpbuf = 0x100893e8
Using __egetcwd()

and the emerge log ends with this:

Comment 14 Art Wallace 2005-11-12 14:35:43 UTC 
PS- at some point last night I was able to do what appears to have been a 
successful compile of tar with the bzip2 flag enabled. While fighting the long 
path name in the patch, I had changed the log to go to ~/getcwd.log. For 
whatever reason, no errors occured during the compile and no log file was 
created. It was late and I wasn't thinking clearly but then I wondered if the 
home directory for root would have been writable by the compile. I don't know 
enough about portage to know.

But since then, I haven't been able to compile tar without the bzip2 flag. 
I've not tried yet to recompile it with the bzip2 again.

Created attachment 72842 [details, diff]
sandbox-getcwd.patch

K, apply this patch, and see if it fixes it.
Comment 16 Art Wallace 2005-11-16 22:39:28 UTC 
Martin,
That patch allowed tar to compile both with and without the bzip2 flag. It 
looks to be a winner for me.
