When including resources in the package and packaging on Ubuntu,
`FileManager` throws a FilePermission error. The docker daemon runs as
root and files to be copied are owned by `root` while the archiver runs
as the current user (`ubuntu` on EC2 Ubuntu). The `FileManager` manages
to copy the files but throws an error after the copy. We suspect the
`FileManager` to perform some kind of operation after the copy and it
fails because of the `root` permission of the files.
See
https://github.com/swift-server/swift-aws-lambda-runtime/issues/449#issuecomment-2595978246
for a description of the problem.
This PR contains code to reproduce the problem, a very simple
workaround, and an integration test.
The workaround consists of
- trapping all errors
- verify if the error is the permission error (Code = 513)
- verify if the files have been copied or not
- if the two above conditions are met, ignore the error, otherwise
re-throw it
I would rather prefer a solution that solves the root cause rather than
just ignoring the error.
We're still investigating the root cause (see [this
thread](https://forums.swift.org/t/filemanager-copyitem-on-linux-fails-after-copying-the-files/77282)
on the Swift Forum and this issue on Swift Foundation
https://github.com/swiftlang/swift-foundation/issues/1125
This adds a test in the `integration_test.yml` workflow to verify that
`libFoundation.so`, `libFoundationInternationalization.so`, and
`lib_FoundationICU.so` and not linked the the function binary.
This is a follow up from the work make by @t089 to ensure that we don't
accidentally link Foundation again in the future.
Remove Foundation :

Add test in CI to ensure we don't link to foundation :
