+# Flow summaries
+
+Flow summaries describe how data flows through methods whose definition is not
+included in the database. For example, methods in the standard library or a gem.
+
+Say we have the following code:
+
+```rb
+x = gets
+y = x.chomp
+system(y)
+```
+
+This code reads a line from STDIN, strips any trailing newlines, and executes it
+as a shell command. Assuming `x` is considered tainted, we want the argument `y`
+to be tainted in the call to `system`.
+
+`chomp` is a standard library method in the `String` class for which we
+have no source code, so we include a flow summary for it:
+
+```ql
+private class ChompSummary extends SimpleSummarizedCallable {
+  ChompSummary() { this = "chomp" }
+
+  override predicate propagatesFlowExt(string input, string output, boolean preservesValue) {
+    input = "Argument[self]" and
+    output = "ReturnValue" and
+    preservesValue = false
+  }
+}
+```
+
+The shared dataflow library will use this summary to construct a fake definition
+for `chomp`. The behaviour of this definition depends on the body of
+`propagatesFlowExt`. In this case, the method will propagate taint flow from the
+`self` argument (i.e. the receiver) to the return value.
+
+If `preservesValue = true` then value flow is propagated. If it is `false` then
+only taint flow is propagated.
+
+Any call to `chomp` in the database will be translated, in the dataflow graph,
+to a call to this fake definition. 
+
+`input` and `output` define the "from" and "to" locations in the flow summary.
+They use a custom string-based syntax which is similar to that used in `path`
+column in the Models as Data format. These strings are often referred to as
+access paths.
+
+Note: The behaviour documented below is tested in
+`dataflow/flow-summaries/behaviour.ql`. Where specific quirks exist, we may
+reference a particular test case in this file which demonstrates the quirk.
+
+# Syntax
+
+Access paths consist of zero or more components separated by dots (`.`). The
+permitted components differ for input and output paths. The meaning of each
+component is defined relative to the implicit context of the component as
+defined by the preceding access path. For example,
+
+```
+Argument[0].Element[1].ReturnValue
+```
+
+refers to the return value of the element at index 1 in the array at argument 0
+of the method call.
+
+## `Argument` and `Parameter`
+
+The `Argument` and `Parameter` components refer respectively to an argument to a
+call or a parameter of a callable. They contain one or more _specifiers_[^1] which
+constrain the range of arguments/parameters that the component refers to. For
+example, `Argument[0]` refers to the first argument.
+
+If multiple specifiers are given then the result is a disjunction, meaning that
+the component refers to any argument/parameter that satisfies at least one of
+the specifiers. For example, `Argument[0, 1]` refers to the first and second
+arguments.
+
+### Specifiers
+
+#### `self`
+The receiver of the call.
+
+#### `<integer>`
+The argument to the method call at the position given by the integer. For
+example, `Argument[0]` refers to the first argument to the call.
+
+#### `<integer>..`
+An argument to the call at a position greater or equal to the integer. For
+example, `Argument[1..]` refers to all arguments except the first one. This
+specifier is not available on `Parameter` components.
+
+#### `<string>:`
+A keyword argument to the call with the given name. For example,
+`Argument[foo:]` refers to the keyword argument `foo:` in the call.
+
+#### `block`
+The block argument passed to the call, if any.
+
+#### `any`
+Any argument to the call, except `self` or `block` arguments.
+
+#### `any-named`
+Any keyword argument to the call.
+
+#### `hash-splat`
+The special "hash splat" argument/parameter, which is written as `**args`.
+When used in an `Argument` component, this specifier refers to special dataflow
+node which is constructed at the call site, containing any elements in a hash
+splat argument (`**args`) along with any explicit keyword arguments (`foo:
+bar`). The node behaves like a normal dataflow node for a hash, meaning that you
+can access specific elements of it using the `Element` component.
+
+For example, the following flow summary states that values flow from any keyword
+arguments (including those in a hash splat) to the return value:
+
+```ql
+input = "Argument[hash-splat].Element[any]" and
+output = "ReturnValue" and
+preservesValue = true
+```
+
+Assuming this summary is for a global method `foo`, the following test will pass:
+
+```rb
+a = source "a"
+b = source "b"
+
+h = {a: a}
+
+x = foo(b: b, **h)
+
+sink x # $ hasValueFlow=a hasValueFlow=b
+```
+
+If the method returns the hash itself, you will need to use `WithElement` in
+order to preserve taint/value in its elements. For example:
+
+```ql
+input = "Argument[hash-splat].WithElement[any]" and
+output = "ReturnValue" and
+preservesValue = true
+```
+```rb
+a = source "a"
+x = foo(a: a)
+sink x[:a] # $ hasValueFlow=a
+```
+
+## `ReturnValue`
+`ReturnValue` refers to the return value of the element identified in the
+preceding access path. For example, `Argument[0].ReturnValue` refers to the
+return value of the first argument. Of course this only makes sense if the first
+argument is a callable.
+
+## `Element`
+This component refers to elements inside a collection of some sort. Typically
+this is an Array or Hash. Elements are considered to have an index, which is an
+integer in arrays and a symbol or string in hashes (even though hashes can have
+arbitrary objects as keys). Elements can also have an unknown index, which means
+we know the element exists in the collection but we don't know where.
+
+Many of the specifiers have an optional suffix `!`. If this suffix is used then
+the specifier excludes elements at unknown indices. Otherwise, these are
+included by default.
+
+### Specifiers
+
+#### `?`
+If used in an input path: an element at an unknown index. If used in an output
+path: an element at any known or unkown index. In other words, `?` in an output
+path means the same as `any`.
+
+#### `any`
+An element at any known or unknown index.
+
+#### `<integer>`, `<integer>!`
+An element at the index given by the integer.
+
+#### `<integer>..`, `<integer>..!`
+Any element at a known index greater or equal to the integer.
+
+#### `<string>`, `<string>!`
+An element at the index given by string. The string should match the result of
+`serialize()` on the `ConstantValue` that represents the index. For a string
+with contents `foo` this is `"foo"` and for a symbol `:foo` it is `:foo`. The
+Ruby values `true`, `false` and `nil` can be written verbatim. See tests 31-33
+for examples.
+
+## `Field`
+A "field" in the object. In practice this refers to a value stored in an
+instance variable in the object. The only valid specifier is `@<string>`, where
+`<string>` is the name of the instance variable. Currently we assume that a
+setter call such as `x.foo = bar` means there is a field `foo` in `x`, backed by
+an instance variable `@foo`.
+
+For example, the access path `Argument[0].Field[@foo]` would refer to the value `"foo"` in
+
+```rb
+x = SomeClass.new
+x.foo = "foo"
+some_call(x)
+```
+
+## `WithElement`
+This component restricts the set of elements that are included in the preceding
+access path to to those at a specific set of indices. The specifiers are the
+same as those for `Element`. It is only valid in an input path.
+
+This component has the effect of copying all relevant elements from the input to
+the output. For example, in the following summary:
+
+```ql
+input = "Argument[0].WithElement[1, 2]" and
+output = "ReturnValue"
+```
+
+any data in indices 1 and 2 of the first argument will be copied to indices 1
+and 2 of the return value. We use this in many Hash summaries that return the
+receiver, in order to preserve any data stored in it. For example, the summary
+for `Hash#to_h` is
+
+```ql
+input = "Argument[self].WithElement[any]" and
+output = "ReturnValue" and
+preservesValue = true
+```
+
+## `WithoutElement`
+This component is used to exclude certain elements from the set included in the
+preceding access path. It takes the same specifiers as `WithElement` and
+`Element`. It is only valid in an input path.
+
+This component has the effect of excluding the relevant elements when copying
+from input to output. It is useful for modelling methods that remove elements
+from a collection. For example to model a method that removes the first element
+from the receiver, we can do so like this:
+
+```ql
+input = "Argument[self].WithoutElement[0]" and
+output = "Argument[self]"
+```
+
+Note that both the input and output refer to the receiver. The effect of this
+summary is that use-use flow between the receiver in the method call and a
+subsequent use of the same receiver will be blocked:
+
+```ruby
+a[0] = source 0
+a[1] = source 1
+
+a.remove_first # use-use flow from `a` on this line to `a` below will be blocked.
+               # there will still be flow from `[post-update] a` to `a` below.
+
+sink a[0]
+sink a[1] # $ hasValueFlow=1
+```
+
+It is also important to note that in a summary such as
+
+```ql
+input = "Argument[self].WithoutElement[0]" and
+output = "ReturnValue"
+```
+
+if `Argument[self]` contains data, it will be copied to `ReturnValue`. If you only want to copy data in elements, and not in the container itself, add `WithElement[any]` to the input path:
+
+```ql
+input = "Argument[self].WithoutElement[0].WithElement[any]" and
+output = "ReturnValue"
+```
+
+See tests 53 and 54 for examples of this behaviour.
+
+
+
+[^1]: I've chosen this name to avoid overloading the word "argument".
