Avi Kivity 55168592ad compaction_manager: fix use-after-free of column_family
Commit cce1a2bce8 ("Use the CPU scheduler")
placed some compaction manager code in a scheduling_group. Unfortunately,
downstream code relied on the callers not deferring, so it can rely
on the column_family's existence. That doesn't happen if the column_family
is removed quickly, as with_scheduling_group() always defers.

Fix applying the scheduling group after we've taken the lock and guaranteed
the stability of the column_family object.

Fixes #3196.

Scylla

Quick-start

$ git submodule update --init --recursive
$ sudo ./install-dependencies.sh
$ ./configure.py --mode=release
$ ninja-build -j4 # Assuming 4 system threads.
$ ./build/release/scylla
$ # Rejoice!

Please see HACKING.md for detailed information on building and developing Scylla.

Running Scylla

  • Run Scylla
./build/release/scylla

  • run Scylla with one CPU and ./tmp as data directory
./build/release/scylla --datadir tmp --commitlog-directory tmp --smp 1
  • For more run options:
./build/release/scylla --help

Building Fedora RPM

As a pre-requisite, you need to install Mock on your machine:

# Install mock:
sudo yum install mock

# Add user to the "mock" group:
usermod -a -G mock $USER && newgrp mock

Then, to build an RPM, run:

./dist/redhat/build_rpm.sh

The built RPM is stored in /var/lib/mock/<configuration>/result directory. For example, on Fedora 21 mock reports the following:

INFO: Done(scylla-server-0.00-1.fc21.src.rpm) Config(default) 20 minutes 7 seconds
INFO: Results and/or logs in: /var/lib/mock/fedora-21-x86_64/result

Building Fedora-based Docker image

Build a Docker image with:

cd dist/docker
docker build -t <image-name> .

Run the image with:

docker run -p $(hostname -i):9042:9042 -i -t <image name>
