Several of the tests in tests/view_complex_test.cc set a cell with a
TTL, and then skip time ahead artificially with forward_jump_clocks(),
to go past the TTL time and check the cell disappeared as expected.
The TTLs chosen for these tests were arbitrary numbers - some had 3 seconds,
some 5 seconds, and some 60 seconds. The actual number doesn't matter - it
is completely artificial (we move the clock with forward_jump_clocks() and
never really wait for that amount of time) and could very well be a million
seconds. But *low* numbers, like the 3 seconds, present a problem on extremely
overcomitted test machines. Our eventually() function already allows for
the possibility that things can hang for up to 8 seconds, but with a 3 second
TTL, we can find ourselves with data being expired and the test failing just
after 3 seconds of wall time have passed - while the test intended that the
dataq will expire only when we explicitly call forward_jump_clocks().
So this patch changes all the TTLs in this test to be the same high number -
100 seconds. This hopefully fixes #3918.

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 the build/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: build/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>
