Stefan Miklosovic created CASSANDRA-18183:
---------------------------------------------
Summary: rat targets do not adhere to build.dir property
Key: CASSANDRA-18183
URL: https://issues.apache.org/jira/browse/CASSANDRA-18183
Project: Cassandra
Issue Type: Bug
Components: Build
Reporter: Stefan Miklosovic
I detected this when I was trying to put my build dir to ramdisk. I have plenty
of RAM available on my workstation (64GB) and I was thinking about moving
"build" dir to ramdisk so I could make it faster a little bit and also spare
some write cycles to ssd. It can look like irrelevant improvement but I think
that if devs are build the project repeatedly times and times again, this can
easily add up.
{code}
mkdir /tmp/cassandra
# in /etc/fstab
tmpfs /tmp/cassandra tmpfs defaults,noatime,size=2048M,x-gvfs-show,mode=1777 0 0
# then sudo mount -a
# I have worktree setup so the build for each branch will end up in different
dir:
# mkdir -p
/tmp/cassandra/{trunk,cassandra-4.1,cassandra-4.0,cassandra-3.11,cassandra-3.0}
{code}
Then in build.properties for each respective branch:
{code}
ant.gen-doc.skip: true
build.dir: /tmp/cassandra/trunk/build
build.dir.lib: /tmp/cassandra/trunk/build/lib
{code}
The problem with this is that it fails on rat, because there is not "build.dir"
property used, it is hardcoded to "build" but there is not anything to rat on
so it will hang.
