Symlinking Crashing - RuntimeError: dictionary changed size during iteration about cider

[kishansairam9]

Fix: kishansairam9@5102a8d

• Instead of deleting key directly from symlinks in remove_symlinks function, create list containing keys to delete
• Iterate over created list and delete the keys from symlinks so that its size is constant throughout the iteration

After Fix:

~/Repos
❯ cider addlink test2 test2
Success! symlinked ~/Repos/test2 -> ~/.cider/symlinks/test2/test2

~/Repos
❯ cider unlink test2
==> Moved ~/.cider/symlinks/test2/test2 -> ~/Repos/test2
