Pre-Release Checks: Laying the Groundwork for Success
The pre-release check phase is absolutely critical for a successful software deployment. Think of it as the final inspection before a grand opening; every detail matters. For our ucomp-pipeline v1.0.21, this stage involves a series of rigorous checks designed to preemptively identify and resolve any potential issues before they impact our production environment. First on the list is to check to make sure no changes to the production config files are needed. This is paramount because configuration files are the backbone of how our pipeline interacts with its environment. Any unintended modifications could lead to unexpected behavior, data corruption, or even a complete system outage. Our team carefully reviews these files, comparing them against the planned changes for v1.0.21 to ensure compatibility and correctness. Following this, we move to add the date to the version line in RELEASES.md. This might seem like a small detail, but accurate documentation is a cornerstone of good software management. The RELEASES.md file serves as a historical record of all versions and their corresponding release dates, making it easier for users to track updates and for developers to reference past releases. Ensuring this date is accurate provides an immediate snapshot of when v1.0.21 officially joined the ranks. The final, yet equally important, pre-release step is to check that the version to release in RELEASES.md matches the version in CMakeLists.txt. Consistency across our build system and documentation is vital. CMakeLists.txt is where the build process is defined, and it must accurately reflect the version being prepared for deployment. A mismatch here could lead to confusion during the build or installation process, potentially causing developers to deploy the wrong version or encounter build errors. By diligently performing these pre-release checks, we establish a solid foundation, significantly reducing the risk of encountering problems once the new version is deployed to production. This methodical approach ensures that v1.0.21 is released with the highest degree of confidence and reliability.
The Release to Production: Going Live!
With all our pre-release checks successfully completed, we now enter the exciting phase of the release to production. This is where version v1.0.21 officially becomes available for general use in our live environment. The process is carefully orchestrated to minimize downtime and ensure a smooth transition. The first action is to merge master to production. Our development typically happens on a 'master' branch, which contains the latest code. Before releasing, we integrate these latest changes into the 'production' branch. This merge operation is a critical step, ensuring that all the features and bug fixes developed since the last release are brought into the code that will be deployed. Thorough code reviews and testing during development help make this merge as seamless as possible. Once the merge is complete and verified, the next step is to push production to origin. This action uploads the updated 'production' branch from our local repositories to the remote repository, making it accessible to the deployment systems and other team members. Pushing to origin ensures that the authoritative version of the code is updated in our central repository. Following this, we tag production. Tagging is a way to mark a specific point in the repository's history, in this case, the exact commit that represents the v1.0.21 release. This tag serves as a permanent reference point, making it easy to identify, check out, and build this specific version in the future. It's like putting a label on a specific box in a warehouse. Finally, we push tags. Just as we push branches, we also need to push our newly created tag to the remote repository. This ensures that everyone working with the repository can see and utilize the release tag. This phase, the release to production, is a carefully managed sequence of events designed to deploy v1.0.21 efficiently and reliably. By following these steps precisely, we aim to provide our users with the latest stable version of the ucomp-pipeline without any disruption to ongoing operations.
Installing Production: Getting v1.0.21 Up and Running
Once version v1.0.21 has been successfully released to production, the next logical step is to install production so that it can be used. This process ensures that the newly deployed version is correctly set up and ready for operation. The installation begins at the source code directory, /hao/acos/sw/src/ucomp-pipeline. Here, the first command is to pull at /hao/acos/sw/src/ucomp-pipeline. This action fetches the latest code from the production branch, ensuring that the local copy of the repository is synchronized with the version that was just pushed. It's like downloading the latest software update to your local machine. After ensuring we have the latest code, we execute production_configure.sh. This script is responsible for configuring the build environment specifically for the production setup. It checks for dependencies, sets up build options, and prepares the system for compilation, tailored to the production requirements. This step is crucial for ensuring that the software is built with the correct settings for its intended operational environment. Following the configuration, we cd build; make. Navigating into the build directory is standard practice in many build systems, and the make command then initiates the compilation process. This step compiles the source code into executable programs and libraries that the ucomp-pipeline requires. It translates the human-readable code into machine-executable instructions. The final, and perhaps most important, installation step is make install when the pipeline is not running. This command installs the compiled software to its designated runtime location on the system. It copies the executables, libraries, and other necessary files to the appropriate directories. Performing this step only when the pipeline is not running is a critical safety measure. Installing while the pipeline is active could lead to inconsistencies, data corruption, or immediate failures as the system tries to use files that are actively being replaced or modified. By carefully following these installation steps, we guarantee that v1.0.21 is correctly deployed and ready to perform its functions within the production environment, ensuring reliability and stability for all users.
Post-Release Checks: Ensuring Everything is Shipshape
The work doesn't stop once v1.0.21 is installed; rigorous post-release checks are essential to confirm that everything is functioning as expected and to prepare for the next development cycle. This phase is about validation and forward planning. The first post-release action is to send an email with new release notes to iguana, detoma, and observers. Communication is key in any collaborative project. This email serves to inform key stakeholders and interested parties about the successful deployment of v1.0.21, detailing the changes, improvements, and any new features included in this version. It ensures that everyone is aware of the update and can refer to the release notes for specific information. Following this communication, we perform the crucial step: in master, increment version in CMakeLists.txt and RELEASES.md. This is where we prepare for the next release. After a version has been successfully deployed, we immediately move to the 'master' branch to increment the version number. This involves updating the CMakeLists.txt file, which dictates the build process and version information, and also updating the RELEASES.md file to reflect that we are now working on a future version. This practice ensures that development continues on a new, unreleased version while the stable v1.0.21 is actively in production. It maintains a clear distinction between what is released and what is under development, preventing accidental releases of incomplete code. These post-release checks are not just about confirming the current success but also about setting the stage for future stability and continuous improvement. They are a testament to our commitment to maintaining a robust and well-documented software pipeline.
Installing at MLSO: Expanding the Reach
Following the successful production release and subsequent checks, a vital step is to install at MLSO. This deployment ensures that the stability and improvements of v1.0.21 are also available in the MLSO environment, expanding its reach and utility. The MLSO installation is scheduled for a day after production release. This deliberate delay allows us to monitor the production environment for any unforeseen issues that might arise immediately after the v1.0.21 rollout. By waiting a day, we gain valuable time to observe the pipeline's performance in its live setting, ensuring that it's truly stable before proceeding with the MLSO deployment. Once this waiting period has passed and the production environment has proven stable, the process at MLSO mirrors the production installation steps, but with specific configurations for that environment. First, we pull at MLSO. This command fetches the latest version of the ucomp-pipeline code from the repository to the MLSO system. It ensures that the MLSO installation is based on the exact code that was released to production. Next, we run mlso_configure.sh. Similar to production_configure.sh, this script configures the build environment, but it's tailored with settings specific to the MLSO infrastructure and requirements. This customization is key to ensuring optimal performance in the MLSO setting. After configuration, the team executes cd build; make. This navigates to the build directory and compiles the source code. The make command turns the source code into executable components, adapted for the MLSO environment through the preceding configuration script. Finally, the critical step: make install when the pipeline is not running. This installs the compiled software onto the MLSO system. As with the production installation, performing this step only when the MLSO pipeline is inactive is crucial to prevent conflicts and ensure data integrity. This systematic approach to installing v1.0.21 at MLSO guarantees that this important version is deployed reliably, extending its benefits to a wider operational context.
