Hi all, Sorry for discussing this again, but before the timing given below, I was wondering what the best approach for downloading OpenJDK files was. Using mercurial, it amounts to: ---------- hg clone http://hg.openjdk.java.net/jdk8u/jdk8u<rev> cd jdk8u<rev> sh get_source.sh sh common/bin/hgforest.sh update -r jdk8u<rev>-b<build> # not really needed ---------- Note that mercurial is needed (obviously), but mercurial depends only on Python, which is a very basic package, and builds very fast (a few tenths of SBU). hgforest is optimized to retrieve several repositories at the same time, so the download time is not too long. Actually, timing gives: ------------- time ( hg clone http://hg.openjdk.java.net/jdk8u/jdk8u60 cd jdk8u60 sh get_source.sh sh common/bin/hgforest.sh update -r jdk8u60-b27 ) ... real 6m31.868s user 0m0.896s sys 0m0.060s
The other approach is to use wget to download tarballs, as proposed by Fernando. For measuring download+unpack time, I use a version slightly different from http://lists.linuxfromscratch.org/pipermail/blfs-dev/2015-May/030258.html: time ( PACKAGE=jdk8u60-b27.tar.bz2 URL=http://hg.openjdk.java.net/jdk8u/jdk8u60 URL_END=archive/$PACKAGE wget $URL/$URL_END tar xf $PACKAGE for additional in corba hotspot jaxp jaxws langtools jdk nashorn; do wget $URL/$additional/$URL_END -O $additional.tar.bz2 mkdir -p jdk8u60-jdk8u60-b27/$additional tar --stripcomponents=1 \ -C jdk8u60-jdk8u60-b27/$additional \ -x -f $additional.tar.bz2 done ) ... real 2m56.273s user 0m8.716s sys 0m2.472s So definitely, the wget approach is shorter. OTOH the mercurial approach is much simpler and less prone to errors. If using wget, I think I'll use some approach similar to what we do for X, as suggested by Fernando, but it would be still complicated, unless maybe we make a file with 4 fields per line: tarball-name, md5 extracted-dirname, final-dirname.
