When decompressing the Standalone version of Confluence an error message is printed at the end of decompression like this:
tar: A lone zero block at 145270
The decompressed result seems to work without problems though. This warning is apparently caused by different versions of tar having different end of file indicators. I can't find a definitive link on the topic, but http://www-1.ibm.com/support/docview.wss?ratlid=cctocbody&rs=984&uid=swg21270445 is okay.
It's odd that this should start happening in our releases suddenly though.

[CONFSERVER-10689] An error message is printed when decompressing confluence-2.7.1-std.tar.gz
Kevin Ross
added a comment - Same issue with confluence 3.0.0.01 on OSX 10.5.7, using command line tar which happens to surprisingly be 1.15.1. Note that double clicking on the tar file in the finder had no issues "unarchiving". Perhaps it uses a different mechanism or different flags.
So I guess the workaround is to avoid being a power user?

causes:
gtar: A lone zero block at 168382
gtar ixvf confluence-2.10.2.tar.gz
causes:
gtar: Unexpected EOF in archive
We are using tar (GNU tar) 1.17 on Solaris 10.

tar: A lone zero block at 176799
Environment:
Mac OS X 10.5.5, tar version: tar (GNU tar) 1.15.1

PLXCOMP-38 has been checked in. I opened up http://jira.codehaus.org/browse/MASSEMBLY-302 to ensure this component is upgraded in the Maven Assembly plugin (The plugin that produces our releases).
This is a known problem in the plexus archiver component that Maven uses to build the tar files for releases.
http://jira.codehaus.org/browse/PLXCOMP-38
When this fix is integrated we will upgrade our Maven plugins that will pull in the new version. For now, this problem is purely cosmetic and the resulting files are not compromised.
Observed in CSP-16817, for confluence-2.7.2.tar.gz (i.e. the WAR version).
tar version: app-arch/tar-1.19-r1, on Gentoo (2.6.19-gentoo-r5).

added a comment - As a workaround in OS X, you can just double-click on the file on your desktop and it seems to expand fine (I haven't tried to run it yet, but there were no errors).

added a comment - And note that it only happens for us for untarring 2.7.1, not 2.7 or any previous versions of Confluence (at least that I've untarred).

added a comment - This happened for us in OS X 10.4.11, fully up to date. Tar version is 1.16.1.

No, the workaround is to say: "Hey, there's that error message. Lucky that I know it's just a version incompatibility problem and that actually the file has been uncompressed successfully." At least that's the one I use.
