FilesystemIterator::FOLLOW_SYMLINKS is currently treated as a directory key mode flag, even though it does not change the way that the key during iteration is set. To address this, SPL_FILE_DIR_KEY has been changed to exclude masking FOLLOW_SYMLINKS for comparison. Addresses bug 80724.

I'd suggest to move SPL_FILE_DIR_FOLLOW_SYMLINKS down into the SPL_FILE_DIR_OTHERS_MASK category instead. As written, this macro doesn't really make sense.

As in changing the value? I wasn't sure if that would be ok to do, unless it's fine since it's non BC anyway?
Currently SPL_FILE_DIR_KEY_MODE_MASK doesn't make sense, so changing the value would allow it to make sense again...
I can move it down too.

At least for master, it's okay to change the value.

Looks like there's a memory leak in the added test: Most likely a pre-existing issue. |

This is enough to cause a leak: |

The leak should be fixed with 44a80b6. |

Thank you, I didn't spend much time looking into the leak, glad it's fixed 👍 |
makes sense again

The OTHERS_MASK should now be 0x00007000 to include the FOLLOW_SYMLINKS flag as well.

👍 Changed and updated tests.

FilesystemIterator::FOLLOW_SYMLINKS is currently treated as a directory
key mode flag, even though it does not change the way that the key
during iteration is determined. To address this, SPL_FILE_DIR_KEY has been
changed to exclude masking FOLLOW_SYMLINKS for comparison.
Addresses bug 80724, though there might be disagreement about the intent of the FOLLOW_SYMLINKS flag.
Submitted against master because this is technically a BC break.
