Hi Liming, Below is the detail why need this change. If you only care usage. Please jump to "How to use it" directly.
Why need: 1. Replication build is not new, you can refer https://reproducible-builds.org for detail 2. The benefit is that 1) make sure the same commit generate same binary so we can sure that it is not modified by anyone 2) store the binary in the repo without concern of different binary with same code. What's barrier in EDK2 implement? 1. Very depend on Toolchain(for example VS, GCC, CLANG). Different toolchain have different feature set and different toolchain version have different feature set. 2. Deploy new toolchain need big effort, include but not limit deploy it in CI CD system, update toolchain, size concern, feature change, etc What's the change: 1. The change want to address one issue that we encounter in replication build: the ASSERT in EDK2 will be different in different environment. For example: file path, back slash or forward slash, etc How to use it: 1. If you want to keep current ASSERT string format. No action is required and the change keep back compatible 2. If you want to customize the ASSERT string format. You can use additional tool to generate PATH and define macro in BuildOptions or tools_def. Note: 1. Replication build need many effort: 1) address the pdb path, 2) address the timestamp, etc 2. This change is not target for resolving all issue in replication build 3. I think it is a small step toward space even though it haven't fix every thing.
