Cargo should warn if `package.include` doesn't contain a `Cargo.toml`

[torkleyy]

How to reproduce:

cargo new hello
cd hello
vi Cargo.toml

Add the following line to the package table:

include = ["hello.txt"]

And then create that file:

touch hello.txt

Finally, try to execute

cargo package

This fails for me with the following error message:

   Packaging hello v0.1.0 (file:///home/thomas/Workspace/hello)
   Verifying hello v0.1.0 (file:///home/thomas/Workspace/hello)
error: failed to verify package tarball

Caused by:
  failed to read `/home/thomas/Workspace/hello/target/package/hello-0.1.0/Cargo.toml`

Caused by:
  No such file or directory (os error 2)

Executing ls target/package/hello-0.1.0/ gives me hello.txt, so it does get included.

Tested versions (same result):

• cargo 0.23.0-nightly (e447ac7 2017-09-27)
• cargo 0.22.0 (3423351 2017-10-06)

As it turns out, I'm stupid and should have added Cargo.toml and src/** to the list, too.

I'll leave this issue open as a suggestion to warn if there's no Cargo.toml included.

Now I got the next problem, I can't include a subdirectory containing a Cargo.toml :(

As there hasn't been any activity here in over 6 months I've marked this as stale and if no further activity happens for 7 days I will close it.

I'm a bot so this may be in error! If this issue should remain open, could someone (the author, a team member, or any interested party) please comment to that effect?

The team would be especially grateful if such a comment included details such as:

• Is this still relevant?
• If so, what is blocking it?
• Is it known what could be done to help move this forward?

Thank you for contributing!

(The cargo team is currently evaluating the use of Stale bot, and using #6035 as the tracking issue to gather feedback.)

If you're reading this comment from the distant future, fear not if this was closed automatically. If you believe it's still an issue please leave a comment and a team member can reopen this issue. Opening a new issue is also acceptable!

This is still an issue.
