Proof of Concept: Reporting a Bug - Inconsistent Behavior Between Name Cases

Issue:

Inconsistent behavior between name cases when compiling contracts in Solidity via forge.

Result of forge build --sizes:

Contract Size (kB) Margin (kB)
Counter 0.247 24.329
Counter2 0.247 24.329
Counter4 0.247 24.329
StdInvariant 2.038 22.538
StdStyle 0.086 24.49
console 0.086 24.49
console2 0.086 24.49
stdError 0.591 23.985
stdJson 0.086 24.49
stdMath 0.086 24.49
stdStorage 0.086 24.49
stdStorageSafe 0.086 24.49

Compilation Details:

  1. Counter.sol is imported in Counter.t.sol and is thus compiled 😄
  2. Counter2.Sol is imported in Counter2.t.sol and is thus compiled 😄
  3. Counter3.Sol exists in src without being imported by other contracts and is NOT compiled! 😞
  4. Counter4.sol exists in src without being imported by other contracts and is compiled 😄

As you can see, the file extension seems to matter when they are not imported. No error or warning message is shown, and the affected files are silently left out of compilation.

This behavior is also consistent in script or test folder.
