Integrating early and often becomes a challenge based on the size and time of software projects, even if developers are integrating on a frequent basis from their local workspaces.
Some development teams even try to avoid parallel development out of fear of merge problems later. Teams must choose the right SCM approach for fostering merging and integration. It ultimately comes down to several factors: Choosing the right branching and merging pattern branching patterns should make it easy for developers and team members to move and integrate code between different branches.
It should be easy and straight-forward to know where a change belongs at any given time. Enforcing merge rules and schedules developers should be able to create private workspaces and branches to allow them to create builds, releases and tests of code before they push those changes to other team members.
Gaining visibility into the merge process a straightforward pattern should give development teams the ability to know where to merge to and from, and when to push changes from one branch to another.
Software Configuration Management Best Practices
Ultimately it s up the team to decide on the frequency in which changes are integrated. There are SCM systems that automatically integrate a team s changes together in real time, this can be a huge benefit for teams that have parallel development needs.
Ultimately it s the team s responsibility to have visibility into that process and be responsible for code changes that should be shared with other team members.
Best Practice 3: Build and Release Frequently with Continuous Integration Taking several days to merge changes from one developer sandbox to another isn t fun or practical. Kent Beck, the creator of extreme Programing, developed the concept of Continuous Integration to address this very issue.
With Continuous Integration CI , code is integrated several times a day rather than just every night or once a week. Code doesn t have a chance to get stale in a private workspace.
In addition to integrating code, CI is the process of performing builds very frequently and doing some basic sanity tests on the build to know if it s good. With this type of rapid build cycle, teams can focus on incremental problems immediately and fix the problems instead of having to wait several days.
Configuration Management Best Practices
Software development organizations can incorporate software configuration management best practices when designing and implementing a continuous integration system to further reap its benefits.
These best practices include the following: Using an SCM system to store and version all source code this includes libraries, components and tests. Utilizing private developer workspaces developers should have a place to check in code, test and build before passing it off to the team.
Enabling local developer builds local build should function the same as the CI builds to avoid unnecessary problems. Frequently updating code in the SCM system make it easy for teams to update code with each other. Establishing a staging and isolation hierarchy create staging environments and branches for each environment or step of the process.
Automating builds at all stages in the hierarchy automate the build process with triggers and events. This practice should occur frequently enough that no intervening window remains between the SCM commit and the build, so that no errors can arise without developers noticing them and correcting them immediately.
This process is certainly easier when utilizing an SCM system with atomic commit capabilities. Best Practice 4: Create a Structure for Distributed Development Collaborating and sharing code with distributed teams is more complex than ever. Teams routinely perform software development in many locations and sometimes test or perform other tasks in another location. This distribution of teams strains the development process.
There are security auditing and integration problems throughout the process. Development teams must appear to be co-located while utilizing the same process, across teams with lower complexity. This means code integrations with other projects should happen in real time, so teams can give each other feedback immediately.
The process must be visible to everyone to ensure they are all on the same page. Data Mining for Problem Management Engineers investigating incidents can mine conguration records to look for corresponding incidents when certain CIs are used in a certain way Enhance Ability to Rebuild In the event of a CI disaster, it is easier to rebuild if the nal production build is known.
If the nal build exists as a drive image, the new hardware can be matched to the last known good build and the image can be restored. Unlike manual processes, recovery can be completed in minutes. Assist with Budgeting Understanding the hardware and software involved in a given CI allows proper costing in the budget plan.
Costing information is also important for ensuring the rm has adequate insurance. Tracking CIs allows IT to rapidly report what capital assets are in use, being decommissioned, or transferred to other departments or divisions.
Assist with Licensing Understanding what software is deployed allows management to track how many tools are in production and properly manage license counts.
Firms want to have enough licenses to avoid legal disputes, but control spending by not having too many.Implementing configuration management: The research described in this publication was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration.
