Currently, if an INF path is an absolute path on Linux (begins with "/"), the "/" character will be removed. If the path is an absolute system path, this creates an invalid path. An example of when this may be an issue is in external dependencies where an INF is within the external dependency, the `set_build_var` flag is set, and DSC files refer to files by its build variable (e.g. `$(SHARED_BINARIES)/Module.inf`). INFs in a binary distribution like this example may contain a [Binaries] section and refer to different section files that can be used by a platform to compose an FFS file. For example, the PE32 (.efi) and DEPEX (.depex) files. In this case, `$(SHARED_BINARIES)` will be an absolute path to the ext dep directory and `FfsInfStatement.__InfParse__` will remove the leading "/" character so the path is invalid. This change first checks if the absolute path will resolve into the current workspace. If it does (as will happen in the shared crypto ext dep example above), it modifies the path to be relative to the workspace so later logic dependent on relative paths can operate on it. If the absolute path is not within the current workspace, it follows previous behavior for backward compatibility to that scenario.

Edk2 Basetools
This folder has traditionally held the source of Python based tools used by EDK2.
The official repo this source has moved to https://github.com/tianocore/edk2-basetools.
This folder will remain in the tree until the next stable release (expected 202102).
There is a new folder under Basetools BinPipWrappers that uses the pip module rather than this tree for Basetools.
By adding the scope pipbuild-win or pipbuild-unix (depending on your host system), the SDE will use the
BinPipWrappers instead of the regular BinWrappers.
Why Move It?
The discussion is on the mailing list. The RFC is here: https://edk2.groups.io/g/rfc/topic/74009714#270 The benefits allow for the Basetools project to be used separately from EDK2 itself as well as offering it in a globally accessible manner. This makes it much easier to build a module using Basetools. Separating the Basetools into their own repo allows for easier CI and contribution process. Additional pros, cons, and process can be found on the mailing list.
How Do I Install It?
By default, EDK2 is tied to and tested with a specific version of the Basetools through pip-requirements.txt.
You can simply run:
pip install -r pip-requirements.txt
This will install the required module, thought we strongly suggest setting up a virtual environment. Additionally, you can also install a local clone of the Basetools as well as a specific git commit.
