Description Paul Moore 2012-02-24 15:38:06 UTC
When trying to update my system, emerge has problems unpacking cyrus-sasl, see "Actual Results" below.

I have seen similar problems with dev-libs/cyrus-sasl-2.1.25 and dev-libs/cyrus-sasl-2.1.25-r1.


Reproducible: Always

Steps to Reproduce:
1. emerge -1v dev-libs/cyrus-sasl

Actual Results:  

These are the packages that would be merged, in order:

Comment 1 Jeroen Roovers (RETIRED) gentoo-dev 2012-02-24 16:29:17 UTC
Looks like something is wrong with either of these:

1) gzip
2) The source tarball, but that would imply the checksum had magically changed
   too.
3) The filesystem you are unpacking the tarball on.

> Looks like something is wrong with either of these:

Do you have any specific tests I could try to narrow down the issue?  I haven't noticed anything else unusual on the system and the simple tests I've tried (below) all seem to indicate everything is okay ...

[SIDE NOTE: I've also removed the source tarball and re-downloaded it multiple times to no avail]

My /var/tmp/portage is current part of my root filesystem, and as I've said earlier, I haven't noticed any other problems - and that includes several other 'emerge -uDv world' operations over the past several weeks.  While it is possible that there is a problem with the filesystem, it seems unlikely that it would only be affecting this package.

strace -f -o strace.txt tar xf /usr/portage/distfiles/cyrus-sasl-2.1.25.tar.gz

+1 on x86 install
it happens only with cyrus-sasl-2.1.25.tar.gz
if i first gunzip and then untar no errors are reported
if i repack the the package no errors are reported however the checksum changes
strangely on another gentoo amd64 box with same tar and gzip versions i can't reproduce it...

Hi,
I've  the same issue on two my systems, both are amd64.

Looks like an upstream issue.
http://www.gzip.org/#faq7
https://bugs.gentoo.org/show_bug.cgi?id=309001

What does the following command output on a failing system?
$ gzip -d -c -- cyrus-sasl-2.1.25.tar.gz | tar xof -
$ echo ${PIPESTATUS[@]}

gzip: stdout: Broken pipe
# echo ${PIPESTATUS[@]}
1 0

But later I found out that it works correctly with my normal user. Then I went to a lunch and after lunch, I was not able to reproduce it. Cyrus-sasl is currently recompiling. 

There was nothing changed during the lunch. No compilation was running.

The output as requested:

# gzip -d -c -- cyrus-sasl-2.1.25.tar.gz | tar xof -
# echo ${PIPESTATUS[@]}
141 0

Also, like the other commenter posted, the package is now building (it made it past the unpacking stage).  Based on the gzip FAQ, it appears that this is something that will happen on occasion; is there anything we can do to prevent it?

Portage does have a check for broken pipe.  It does check PIPESTATUS output after unpacking and ignores 141 - 141 being the return code for SIGPIPE (128+13).  So, as long as PIPESTATUS is 0 or 141, we are fine.

I am - somewhat reluctantly - closing this as WORKSFORME.  Please do reopen if there are any suggestions.

I was bitten by this bug today (changed an USE flag). Annoying. Had to uncompress, re-compress and ebuild manifest tu build successfully. The original tar.gz is 5MB, my recompressed tar.gz is less than 2MB, so THERE IS something wrong with the official package.
