Make all networking code mockable #21878

  1. vasild commented at 4:04 pm on May 7, 2021: contributor

    This is a roadmap PR. It can be merged, but it can also be split into separate PRs and to get proper thorough review it is split.

    Add wrapper methods to the syscalls accept(), setsockopt(), getsockname(), bind(), listen() in the Sock class (e.g. Sock::Accept()). Those methods can be overriden (mocked) by unit tests (existent example in master) and by fuzz tests (existent example in master).

    Change everybody to use Sock instead of SOCKET.

    Move the functionality of CConnman::SocketEvents() to a mockable method of the Sock class.

    6bed261aaf...272ecad4bf:

    • Rebase
    • Fix #21744
    • To denote an invalid socket: use an empty shared_ptr/unique_ptr to Sock (that owns nullptr) instead of a Sock object that contains m_socket equal to INVALID_SOCKET. This way high-level callers never need to lookup the internal file descriptor of Sock.

    The cast was not added in this PR. I am leaving it as is because it is unrelated to the change and without it, it is easier to see that only getsockname has been changed to sock.GetSockName.

    Should this be marked as draft since it is a parent PR?

    vasild this may be able to be closed now that all of the child PRs have been merged.

    Given that the majority of commits in this pull haven’t been merged, I don’t think so.

    Should this be marked as draft since it is a parent PR?

    Could be, I am not sure. The reason I did not make it a draft is because it can be merged as it is - there is no danger that something bad will happen if it gets merged (assuming there are reviewers who ACK it). The reason I split it into smaller PRs is solely to ease review. Should I make it draft?

    @vasild this may be able to be closed now that all of the child PRs have been merged.

    Given that the majority of commits in this pull haven’t been merged, I don’t think so.

    Right, there are two pieces left - #26312 which I just opened and the tests themselves (which depend on that PR, thus no separate PR for them yet).

  174. i2p: avoid using Sock::Get() for checking for a valid socket 
    Peeking at the underlying socket file descriptor of `Sock` and checkig
if it is `INVALID_SOCKET` is bad encapsulation and stands in the way of
testing/mocking/fuzzing.

Instead use an empty unique_ptr to denote that there is no valid socket.
    1a23f0cfd6
  175. net: don't check if the socket is valid in GetBindAddress() 
    The socket is always valid (the underlying file descriptor is not
`INVALID_SOCKET`) when `GetBindAddress()` is called.
    f5c57839ea
  176. net: don't check if the socket is valid in ConnectSocketDirectly() 
    The socket is always valid (the underlying file descriptor is not
`INVALID_SOCKET`) when `ConnectSocketDirectly()` is called.
    7426958ad4
  177. net: remove now unnecessary Sock::Get() 
    `Sock::Get()` was used only in `sock.{cpp,h}`. Remove it and access
`Sock::m_socket` directly.

Unit tests that used `Get()` to test for equality still verify that the
behavior is correct, indirectly, by testing whether the socket is closed
or not.

  178. net: remove Sock default constructor, it's not necessary 2bcbe87424
  179. fuzz: add CConnman::OpenNetworkConnection() to the tests 
    Now that all network calls done by `CConnman::OpenNetworkConnection()`
are done via `Sock` they can be redirected (mocked) to `FuzzedSocket`
for testing.

    🐙 This pull request conflicts with the target branch and needs rebase.

  189. vasild commented at 11:34 am on October 4, 2023: contributor

    All the functional bits of this are now merged. Thank you all!

    This enables extending the test framework to be able to call any method, without worries that it may end up doing OS syscalls (try to create sockets, open connections, etc). A PR that does some of that is in #28584 (= last 4 commits from this PR).

    Closing as complete.
