Problem
Since updating to 1.46.0, for some reason we can't build our application if a git clone is using sparse checkouts.
Steps
c:\projects>cargo init foo
c:\projects>cd foo\
c:\projects\foo>git init Initialized empty Git repository in C:/projects/foo/.git/
c:\projects\foo>mkdir bar
c:\projects\foo>touch bar/test.txt
c:\projects\foo>echo fn main() { () } > build.rs
c:\projects\foo>vim build.rs
c:\projects\foo>ls
bar build.rs Cargo.toml src
c:\projects\foo>cargo run
Compiling foo v0.1.0 (C:\projects\foo)
Finished dev [unoptimized + debuginfo] target(s) in 1.31s
Running `target\x86_64-pc-windows-msvc\debug\foo.exe`
Hello, world!
c:\projects\foo>git sparse-checkout init --cone
c:\projects\foo>git sparse-checkout add src
c:\projects\foo>cargo run
error: failed to determine package fingerprint for build script for foo v0.1.0 (C:\projects\foo)
Caused by:
failed to determine the most recently modified file in c:\projects\foo
Caused by:
failed to determine list of files in c:\projects\foo
Caused by:
did not expect repo at c:/projects/foo/.git/ to be bare
c:\projects\foo>
Possible Solution(s)
I have no idea. Sorry!
Notes
Output of cargo version: cargo 1.46.0 (149022b 2020-07-17)
As far as I can tell this really breaks things in a solid way. Just disabling sparse-checkout after this isn't enough to recover.
