This patchset adddresses two problems with shadowable deletions handling
in SSTables 3.x. ('mc' format).
Firstly, we previously did not set a flag indicating the presence of
extended flags byte with HAS_SHADOWABLE_DELETION bitmask on writing.
This would break subsequent reading and cause all types of failures up
to crash.
Secondly, when reading rows with this extended flag set, we need to
preserve that information and create a shadowable_tombstone for the row.
Tests: unit {release}
+
Verified manually with 'hexdump' and using modified 'sstabledump' that
second (shadowable) tombstone is written for MV tables by Scylla.
+
DTest (materialized_views_test.py:TestMaterializedViews.hundred_mv_concurrent_test)
that originally failed due to this issue has successfully passed locally.

* 'projects/sstables-30/shadowable-deletion/v4' of https://github.com/argenet/scylla:
tests: Add tests writing both regular and shadowable tombstones to SSTables 3.x.
tests: Add test covering writing and reading a shadowable tombstone with SSTables 3.x.
sstables: Support Scylla-specific extension for writing shadowable tombstones.
sstables: Introduce a feature for shadowable tombstones in Scylla.db.
memtable: Track regular and shadowable tombstones separately in encoding_stats_collector.
sstables: Error out when reading SSTables 3.x with Cassandra shadowable deletion.
sstables: Support checking row extension flags for Cassandra shadowable deletion.

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>
