Sean, Matthew needs to join the edk2.groups.io and sends message from the registered mail address in order to send out message to everyone in the forum. I just checked and didn't find any blocking messages from Matthew in the groups.io website. I copied edk2-de...@lists.01.org<mailto:edk2-de...@lists.01.org> in this mail so everyone in the forum can get notified before the meeting.

I think it would be good to get the message out to the list prior to the design meeting.

I'd like to get on the agenda for the Thursday (April 16th) design meeting with this topic. I'm planning on talking through the reasoning and current thinking for 5 minutes and having a discussion. I expect at least 20-30 minutes of discussion. Here's a basic overview of the what and the why behind this proposal: Why a separate repo? The recent efforts in expanding the role of CI in the platform and core code of EDK2 will pay big dividends in the future, leading to higher quality code and easier integrations for everyone. Having basetools as it's own repo would simplify adding a similar CI/linting process and unit-tests to the basetools python code, leading to higher quality code. A second major benefit is it would allow others that write tools for UEFI and Edk2 to leverage this vast resource of python code using standard python package inclusion. It would allow those tools to be decoupled from edk2 source and provide a consistent and managed user experience. The python project would be published as a Pip module for those that want to leverage the basetools modules the same way they leverage the existing python ecosystem. Packing basetools as a pip module, would reach the most developers and provide the most flexibility and versatility. There are numerous way this could be used; Pip is just one method suggested here. Other ways to leverage this are described below. Why a pip module? The investment into basetools is sizable and it has some amazing functionality that's difficult to reproduce. For example, the DSC, FDF, INF, and DEC parsers handle an incredible amount of edge cases. If I wanted to write a tool that could do a CI validation check or build a UEFI capsule, currently I would need to clone all of EDK2 to get basetools. If it was in a separate repo and available as a wheel, as a developer, I could include it via pip and have that dependency managed with virtual environment or just in the global cache. In addition, other tools that currently are difficult to build would become possible with access to the Basetools functionality. However, there have been some concerns expressed about having a global basetools and the impact this has on developers with multiple workspaces (potentially at different versions). There are several tools and strategies to consider for managing this dependency. Some outlined below. How will this change your workflow? If this moved there would have to be a change for all platforms using edk2 and we have been evaluating options. These could become requirements a developer must do before building edk2 or with minimal effort could be added to the edksetup or build scripts. These can also be more easily isolated if python virtual environments are used. For those just consuming released versions of basetools python code: Option A: leverage Python package management and install a released version from Pypi into a per project virtual environment. Option B: leverage pip to install from the git repo at known tag/release (pip_requirements) For those wanting to do active development of basetools within an edk2 project: Option C: Clone the python package source and install the package locally (pip install -e ./). All changes made in the local package are reflected into your python site packages. We have a demo of what this would look like: https://github.com/matthewfcarlson/edk2-pytool-base/<https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fmatthewfcarlson%2Fedk2-pytool-base%2F&data=02%7C01%7Csean.brogan%40microsoft.com%7C4717479fbabf487c7e5208d7e0ec4a1a%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637225177772777671&sdata=yk559NU%2FbBbwSBEWo481w50gCObUy4h8G9BJEVIPO4I%3D&reserved=0> And the EDK2 that leverages it https://github.com/matthewfcarlson/edk2/tree/feature/pip-basetools<https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fmatthewfcarlson%2Fedk2%2Ftree%2Ffeature%2Fpip-basetools&data=02%7C01%7Csean.brogan%40microsoft.com%7C4717479fbabf487c7e5208d7e0ec4a1a%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637225177772787672&sdata=w3BGez4Tp%2BpcQ%2Fk%2F7QZ30yKvCcyHGiqzYbAFgskPjkA%3D&reserved=0> What happens next? Right now, we're gathering feedback and seeing if anyone has an concerns or platforms that this would not work for. We'd love to hear what you have to say. Baring any serious concerns, we'd move forward with: 1. Create new GitHub repo on tianocore for the basetools project 2. Develop the testing, PR, and release process 3. Release the initial version to pypi 4. Delete the source folder in edk2 repo and replace with readme and method to get pip version installed 5. Continually improve basetools and add more testing What's the long-term plan? The current tentative long term plan is to merge some or all of basetools in with the existing edk2-pytool-library repo. This is still an active conversation, and we'd like to hear your thoughts. Matthew Carlson Core UEFI Microsoft -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
