- policies before depending on it
-
-On Fedora it's apparently not allowed so we'll have to fall back to the
-thread-spawner thread in GThreadPool instead.

-Subject: [PATCH] Refactor g_socket_client_connect_async()
-
-This is a fairly large refactoring. The highlights are:
-
-- Removing in-progress connections/addresses from GSocketClientAsyncConnectData:
-
-  This caused issues where multiple ConnectionAttempt's would step over eachother
-  and modify shared state causing bugs like accidentally bypassing a set proxy.
-
-  Fixes #1871
-  Fixes #1989
-  Fixes #1902
-
-- Cancelling address enumeration on error/completion
-
-- Queuing successful TCP connections and doing application layer work serially:
-
-  This is more in the spirit of Happy Eyeballs but it also greatly simplifies
-  the flow of connection handling so fewer tasks are happening in parallel
-  when they don't need to be.
-
-  The behavior also should more closely match that of g_socket_client_connect().
-
-- Better track the state of address enumeration:
-
-  Previously we were over eager to treat enumeration finishing as an error.
-
-  Fixes #1872
-  See also #1982
-
-- Add more detailed documentation and logging.
-
-Closes #1995

--        to the rest of the connection (tls, proxies, etc) which do not

-+     as possible as per Happy Eyeballs (RFC 8305). This complicates flow quite a
-+     bit but we can describe it in 3 sections:
-+
-+     Firstly we have address enumeration (DNS):
-+       - This may be triggered multiple times by enumerator_next_async().
-+       - It also has its own cancellable (data->enumeration_cancellable).
-+       - Enumeration is done lazily because GNetworkAddressAddressEnumerator
-+         also does work in parallel and may lazily add new addresses.
-+       - If the first enumeration errors then the task errors. Otherwise all enumerations
-+         will potentially be used (until task or enumeration is cancelled).
-+
-+      Then we start attempting connections (TCP):
-+        - Each connection is independent and kept in a ConnectionAttempt object.
-+          - They each hold a ref on the main task and have their own cancellable.
-+        - Multiple attempts may happen in parallel as per Happy Eyeballs.
-+        - Upon failure or timeouts more connection attempts are made.
-+          - If no connections succeed the task errors.
-+        - Upon success they are kept in a list of successful connections.
-+
-+      Lastly we connect at the application layer (TLS, Proxies):
-+        - These are done in serial.
-+          - The reasoning here is that Happy Eyeballs is about making bad connections responsive
-+            at the IP/TCP layers. Issues at the application layer are generally not due to
-+            connectivity issues but rather misconfiguration.
-+        - Upon failure it will try the next TCP connection until it runs out and
-+          the task errors.
-+        - Upon success it cancels everything remaining (enumeration and connections)
-+          and returns the connection.
