Building Couchbase

The instructions provided below specify the steps to build Couchbase version 6.0.4 on Linux on IBM Z for following distributions:

Ubuntu 18.04
RHEL (7.6, 7.7, 8.1)
SLES 12 SP5

General Notes:

When following the steps below please use a standard permission user unless otherwise specified.
A directory /<source_root>/ will be referred to in these instructions, this is a temporary writable directory anywhere you'd like to place it.

Step 1 : Install Dependencies

Download the Repo tool and ensure that it has execute permissions

cd $SOURCE_ROOT
curl https://storage.googleapis.com/git-repo-downloads/repo > repo
chmod a+x repo

Step 3 : Build and test Couchbase

3.1) Clone Couchbase

Clone the Couchbase 6.0.4 release using the the manifest file via Repo tool with the init and sync commands

mkdir -p $SOURCE_ROOT/couchbase
cd $SOURCE_ROOT/couchbase
git config --global user.email your@email.addr
git config --global user.name  your_name
../repo init -u git://github.com/couchbase/manifest -m released/couchbase-server/6.0.4.xml
../repo sync

RHEL

sudo ln -s $GOPATH/bin/goyacc /usr/lib/golang/pkg/tool/linux_s390x/
sudo ln -sf /usr/lib/golang/pkg/tool/linux_s390x/goyacc /usr/lib/golang/pkg/tool/linux_s390x/yacc

Step 4 : Build Couchbase

cd $SOURCE_ROOT/couchbase/
make

Step 5 : Run test cases

sudo ldconfig
cd $SOURCE_ROOT/couchbase/build/
ctest

Note: The following errors occur exclusive to Z. These are only problems with the written test cases, and do not indicate problems in couchbase itself.

memcached-timestamp-test: fails if the user is in a timezone other than EDT.
The following tests fail because of incorrect copying of their results into the returned value. The results are copied as little-endian values into a big-endian 64-bit word.

	ep_testsuite_basic.ephemeral.comp_off
	ep_testsuite_basic.ephemeral.comp_passive
	ep_testsuite_basic.ephemeral.comp_active

memcached-hostutils-test fails on RHEL 7.7 due to a bug in the test code that sometimes causes a port name string to be interpreted as a number, which results in an exception being thrown.
cbsasl-password-database fails on Ubuntu 18.04 as the cyrpto algorithm being tested -- HMAC (SHA512) -- is not distributed in Ubuntu 18.04.
memcached-auditconfig-test fails when json does not throw an exception when creating a string on a non-existant component.
memcached_testapp.default.TransportProtocols/LegacyUsersTest fails on Ubuntu 18.04, as SCRAM-SH1 is no longer distributed.
memcached_testapp.(default & ep).TransportProtocols/XattrTest fails because they compare a little-endian crc32c result to the system crc32c, which is big-endian.
Below test cases might fail in case IPv4/IPv6 is not configured:

	memcached_testapp.default.TransportProtocols/ArithmeticTest
	memcached_testapp.default.TransportProtocols/ArithmeticXattrOnTest

Below test cases fail if python external library load function ctypes.CDLL() is not working:

	couchstore-purge
	couchstore-rewind
	couchstore-changecount

Step 6 : Start the server

Use the below command to start Couchbase Server
```
$SOURCE_ROOT/couchbase/install/bin/couchbase-server -- -noinput &
```
You can view the Couchbase UI at http://hostname:8091
