Cognitive Complexity
Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.
A method's cognitive complexity is based on a few simple rules:
- Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
- Code is considered more complex for each "break in the linear flow of the code"
- Code is considered more complex when "flow breaking structures are nested"

Checks that the cyclomatic complexity of methods is not higher than the configured maximum. The cyclomatic complexity is the number of linearly independent paths through a method. The algorithm counts decision points and adds one.
An if statement (or unless or ?:) increases the complexity by one. An else branch does not, since it doesn't add a decision point. The && operator (or keyword and) can be converted to a nested if statement, and ||/or is shorthand for a sequence of ifs, so they also add one. Loops can be said to have an exit condition, so they add one. Blocks that are calls to builtin iteration methods (e.g. `ary.map{...}) also add one, others are ignored.

Checks for non-atomic file operation. And then replace it with a nearly equivalent and atomic method.
These can cause problems that are difficult to reproduce, especially in cases of frequent file operations in parallel, such as test runs with parallel_rspec.
For examples: creating a directory if there is none, has the following problems
An exception occurs when the directory didn't exist at the time of exist?
,
but someone else created it before mkdir
was executed.
Subsequent processes are executed without the directory that should be there
when the directory existed at the time of exist?
,
but someone else deleted it shortly afterwards.
Safety:
This cop is unsafe, because autocorrection change to atomic processing. The atomic processing of the replacement destination is not guaranteed to be strictly equivalent to that before the replacement.
Example:
# bad - race condition with another process may result in an error in `mkdir`
unless Dir.exist?(path)
FileUtils.mkdir(path)
end
# good - atomic and idempotent creation
FileUtils.mkdir_p(path)
# bad - race condition with another process may result in an error in `remove`
if File.exist?(path)
FileUtils.remove(path)
end
# good - atomic and idempotent removal
FileUtils.rm_f(path)
