Mauro,

I think the archive is generated incorrectly. Could you take a look and
see why? I shamefully admit I still am not sure where you did what to
generate these ;)


Basically, I run a script like the one below once a day at the crontab:

#!/bin/bash
LANG=C
PATH=/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games

DIR=/some_temp_location/dtv-scan-tables

DATE="`git log -n1 '--pretty=format:%h %ai' |perl -ne 'print "$2-$1" if 
(m/([\da-f]+)\s+(\S+)/)'`"

TODAY_TAR=dtv-scan-tables-$DATE.tar
FILE="$TODAY_TAR.bz2"
REPO=/the_www_location/downloads/dtv-scan-tables/


run() {
        echo $@
        $@
        if [ "$?" != "0" ]; then
                echo "Error $?. Please fix."
                exit -1
        fi
}

run cd $DIR
run git pull /git/dtv-scan-tables.git/ master

CHANGES=`git log --pretty=oneline -n1`
if [ "$CHANGES" = "`cat .changes`" ]; then
        echo "tarball already updated to the latest changeset."
        echo "Nothing to do."
        exit;
fi

git archive --format tar --prefix "/usr/share/dvb/" HEAD >$TODAY_TAR
run bzip2 -f $TODAY_TAR

run mv $FILE $REPO
run ln -sf $FILE $REPO/dtv-scan-tables-LATEST.tar.bz2
(cd $REPO; md5sum *.bz2 > md5sum)
echo $CHANGES > .changes

Hi Oliver,

the tar archives at
http://linuxtv.org/downloads/dtv-scan-tables/
are broken.
xxd dtv-scan-tables-2013-04-12-495e59e.tar | less shows:

| 0000000: 6769 7420 6172 6368 6976 6520 2d2d 666f  git archive --fo
| 0000010: 726d 6174 2074 6172 202d 2d70 7265 6669  rmat tar --prefi
| 0000020: 7820 2f75 7372 2f73 6861 7265 2f64 7662  x /usr/share/dvb
| 0000030: 2f20 4845 4144 0a70 6178 5f67 6c6f 6261  / HEAD.pax_globa
| 0000040: 6c5f 6865 6164 6572 0000 0000 0000 0000  l_header........

It seems like the git archive commandline somehow ended in the tarball.
E.g. the tarball should start with pax_global_header and not with "git
archive".


Thanks for pointing it to me. I fixed the script.

Confirmed, it now shows proper archives.

Could you manually remove 'dtv-scan-tables-2013-04-12*' as that isinvalid so shouldn't be mirrored/downloaded really.


Thanks,

Oliver
