Introduction

This plugin integrates CMVC to Hudson.

At the moment, it supports:

• Polling a CMVC family to automatically start builds when changes are detected;
• Ability to customize what characterizes a "change" by providing a custom TrackView Report where clause;
• Delegating checkout/update logic to an external script.

This plugin utilizes CMVC's Report command to query the family for changes. In the default mode, first it looks for all integrated tracks - within the specified releases - between the last build time and the current time (-view TrackView). Then it performs another query to find all files included in these tracks (-view ChangeView). The former query can be easily customized by providing a custom where clause.

Changes and modifications details are detected by running commands similar to the following:

Report -family family<at:var at:name="localhost" />6666 -raw -view TrackView
-where lastUpdate between $lastBuild
and $now and state = 'integrated'
and releaseName in ('RC_123')
order by defectName


Report -family family<at:var at:name="localhost" />6666 -raw -view ChangeView
-where defectName in ('1','2')
and releaseName in ('RC_123')
order by defectName

These queries provide all the necessary information for generating a Hudson´s change log set.

We all know CMVC is considered an obsolete SCM. However we also know there are still some people using it out there. So, why not provide them with a nice way to integrate it with Hudson and make our lives less miserable .

Configuration

System configuration

It has only one global configuration parameter: the cmvc executables directory path.

Usually this directory is already part of the PATH environment variable.

Job configuration

Jobs utilising CMVC have to define the folowing properties:

Fill in each of the settings:

• Family - The CMVC family. The following format is expected: family(at)host(at)port
• Releases - Release names separated by comma (,)
• Become User - User used to connect to CMVC. Usually a family superuser. If left blank the CMVC_BECOME environment variable will be used instead. This user must have permission to access the current family from within Hudson's host.
• Checkout Script - Script that will perform the checkout/update logic. Besides the default Hudson's env variables, the following environment variables are also made available to the script: CMVC_FAMILY, CMVC_BECOME and CMVC_RELEASES. This script will take a list of trackNames separated by space as the first parameter. Itn will be normally used to create a new Level containing the provided integrated tracks (which are the same tracks detected by the polling).

Optionally, you can hit the Advanced... button and configure the TrackView Report where clause.

There are 3 available implicit variables that can be used in the custom where clause (prefixed by $):

1. now - current time
2. lastBuild - last build datetime
3. releases - releases ( properly quoted to be used in "IN" statement )
