Ffi

Python bindings for the Pact FFI.

This module provides a Python interface to the Pact FFI. It is a thin wrapper around the C API, and is intended to be used by the Pact Python client library to provide a Pythonic interface to Pact.

Warning

This module is not intended to be used directly by Pact users. Pact users should use the Pact Python client library instead. No guarantees are made about the stability of this module's API.

Developer Notes

This modules should provide the following only:

• Basic Enum classes
• Simple wrappers around functions, including the casting of input and output values between the high level Python types and the low level C types.
• Simple wrappers around some of the low-level types. Specifically designed to automatically handle the freeing of memory when the Python object is destroyed.

These low-level functions may then be combined into higher level classes and modules. Ideally, all code outside of this module should be written in pure Python and not worry about allocating or freeing memory.

During initial implementation, a lot of these functions will simply raise a NotImplementedError.

For those unfamiliar with CFFI, please make sure to read the CFFI documentation.

Handles

The Rust library exposes a number of handles to internal data structures. This is done to avoid exposing the internal implementation details of the library to users of the library, and avoid unnecessarily casting to and from possibly complicated structs.

In the Rust library, the handles are thin wrappers around integers, and unfortunately the CFFI interface sees this and automatically unwraps them, exposing the underlying integer. As a result, we must re-wrap the integer returned by the CFFI interface. This unfortunately means that we may be subject to changes in private implementation details upstream.

Freeing Memory

Python has a garbage collector, and as a result, we don't need to worry about manually freeing memory. Having said that, Python's garbace collector is only aware of Python objects, and not of any memory allocated by the Rust library.

To ensure that the memory allocated by the Rust library is freed, we must make sure to define the __del__ method to call the appropriate free function whenever the Python object is destroyed.

Note that there are some rather subtle details as to when this is called, when it may never be called, and what global variables are accessible. This is explained in the documentation for __del__ above, and in Python's garbage collection module.

Error Handling

The FFI function should handle all errors raised by the function call, and raise an appropriate Python exception. The exception should be raised using the appropriate Python exception class, and should be documented in the function's docstring.

OwnedString(ptr: cffi.FFI.CData)

This logger does nothing until pactffi_logger_apply has been called.

Types of sinks can be specified:

• stdout (pactffi_logger_attach_sink("stdout", LevelFilter_Info))

Usage

int result = pactffi_logger_attach_sink("file /some/file/path", LogLevel_Filter);

Error Handling

The return error codes are as follows:

• -1: Can't set logger (applying the logger failed, perhaps because one is applied already).
• -2: No logger has been initialized (call pactffi_logger_init before any other log function).
• -3: The sink specifier was not UTF-8 encoded.
• -4: The sink type specified is not a known type (known types: "stdout", "stderr", or "file /some/path").
• -5: No file path was specified in a file-type sink specification.
• -6: Opening a sink to the specified file path failed (check permissions).

Safety

This function checks the validity of the passed-in sink specifier, and errors out if the specifier isn't valid UTF-8. Passing in an invalid or NULL pointer will result in undefined behaviour.

The returned structure must be deleted with provider_state_delete.

Since it is a copy, the returned structure may safely outlive the SynchronousMessage.

Error Handling

On failure, this function will return a variant other than Success.

This function may fail if the index requested is out of bounds, or if any of the Rust strings contain embedded null ('\0') bytes.

with_header_v2(interaction: InteractionHandle, part: InteractionPart, name: str, index: int, value: str) -> None

Configures a header for the Interaction.

Rust pactffi_with_header_v2

To setup a header with multiple values, you can either call this function multiple times with a different index value:

with_header_v2(handle, part, "Accept-Version", 0, "2")
with_header_v2(handle, part, "Accept-Version", 0, "3")

Or you can call it once with a JSON value that contains multiple values:

with_header_v2(
    handle,
    part,
    "Accept-Version",
    0,
    json.dumps({"value": ["2", "3"]}),
)

The JSON value can also contain a matcher, which will be used to match the query parameter value. For example, a semver matcher might look like this:

with_query_parameter_v2(
    handle,
    "Accept-Version",
    0,
    json.dumps({
        "value": "1.2.3",
        "pact:matcher:type": "regex",
        "regex": r"\d+\.\d+\.\d+",
    }),
)

    Configures a header for the Interaction.

    [Rust `pactffi_with_header_v2`](https://docs.rs/pact_ffi/0.4.19/pact_ffi/?search=pactffi_with_header_v2)

    To setup a header with multiple values, you can either call this
    function multiple times with a different index value:

    ```python
    with_header_v2(handle, part, "Accept-Version", 0, "2")
    with_header_v2(handle, part, "Accept-Version", 0, "3")
    ```

    Or you can call it once with a JSON value that contains multiple values:

    ```python
    with_header_v2(
        handle,
        part,
        "Accept-Version",
        0,
        json.dumps({"value": ["2", "3"]}),
    )
    ```

    The JSON value can also contain a matcher, which will be used to match the
    query parameter value. For example, a semver matcher might look like this:

    ```python
    with_query_parameter_v2(
        handle,
        "Accept-Version",
        0,
        json.dumps({
            "value": "1.2.3",
            "pact:matcher:type": "regex",
            "regex": r"\d+\.\d+\.\d+",
        }),
    )
    ```

with_multipart_file(interaction: InteractionHandle, part: InteractionPart, content_type: str, file: str, part_name: str) -> StringResult

Adds a binary file as the body as a MIME multipart.

Will use a mime type matcher to match the body. Returns an error if the interaction or Pact can't be modified (i.e. the mock server for it has already started) or an error occurs.

Rust pactffi_with_multipart_file

• interaction - Interaction handle to set the body for.
• part - Request or response part.
• content_type - Expected content type of the file.
• file - path to the example file
• part_name - name for the mime part

This function can be called multiple times. In that case, each subsequent call will be appended to the existing multipart body as a new part.

Safety

The content type, file path and part name must be valid pointers to UTF-8 encoded NULL-terminated strings. Passing invalid pointers or pointers to strings that are not NULL terminated will lead to undefined behaviour.

Error Handling

If the file path is a NULL pointer, it will set the body contents as as an empty mime-part. If the file path does not point to a valid file, or is not able to be read, it will return an error result. If the content type is a null pointer, or can't be parsed, it will return an error result.
