cargo package is not working

[EduardoBautista]

The cargo package command results in:

   Packaging hello_world v0.0.1 (file:///Users/eduardobautista/Projects/hello_world)
   Verifying hello_world v0.0.1 (file:///Users/eduardobautista/Projects/hello_world)
failed to verify package tarball

This is on a newly generated cargo project using the October 31st build 492bc86 on OS X.

[EduardoBautista]

Also, even if I pass --no-verify the tarball will be empty.

Can you paste the full error with cargo package -v

[EduardoBautista]

   Packaging hello_world v0.0.1 (file:///Users/eduardobautista/Projects/hello_world)
   Verifying hello_world v0.0.1 (file:///Users/eduardobautista/Projects/hello_world)

[EduardoBautista]

Updated rust and cargo before running cargo package -v

[alexcrichton]

I still can't seem to reproduce this, does it still reproduce for you on a recent cargo?

[EduardoBautista]

@alexcrichton Yes, just tested on the latest nightly. Maybe it is something about my computer.

[alexcrichton]

Can you provide the exact set of commands to reproduce this?

[EduardoBautista]

@alexcrichton Sorry for the late response! Here are the steps:

cargo new hello_world --bin
cd hello_world
cargo package --verbose

The cargo package command resulted in this:

   Packaging hello_world v0.0.1 (file:///Users/eduardobautista/Projects/hello_world)
   Verifying hello_world v0.0.1 (file:///Users/eduardobautista/Projects/hello_world)
failed to verify package tarball

Caused by:

It looks like this is happening because the newly created folder is a new git repository and doesn't have any files in its index. This means that no files are copied into the folder (because cargo thinks the project has no files). We should probably run git add . essentially whenever we create a new git repository.

[steveklabnik]

git add . is probably a bad idea. If you check out my suggestions for what cargo package should do over in #841 , it would prevent this from happening in a way that doesn't automatically add possibly private files to repos :)

[steveklabnik]

(and it would be git add -A iirc)

[alexcrichton]

Oh I'm not saying that we should run git add on cargo package, only on cargo new where the only files in the directory are those that we just generated.

[steveklabnik]

Ah!

Hit this today as well.

Bump.

EDIT
I found the solution.

Cargo is apparently not using case-insensitive paths on OSX systems (though it probably should).

I'm not sure how it happened, but the folder "Code" has technically been renamed to "code", perhaps from the terminal... apparently this hadn't been set in some part of the metadata, so renaming the folder in Finder did the trick.
