/** |
||||||
|
`ReachabilityWeakifier` weakly wraps the `Reachability` class |
||||||
|
in order to break retain cycles when interacting with CoreFoundation. |
||||||
|
|
||||||
|
CoreFoundation callbacks expect a pair of retain/release whenever an |
||||||
|
opaque `info` parameter is provided. These callbacks exist to guard |
||||||
|
against memory management race conditions when invoking the callbacks. |
||||||
|
|
||||||
|
#### Race Condition |
||||||
|
|
||||||
|
If we passed `SCNetworkReachabilitySetCallback` a direct reference to our |
||||||
|
`Reachability` class without also providing corresponding retain/release |
||||||
|
callbacks, then a race condition can lead to crashes when: |
||||||
|
- `Reachability` is deallocated on thread X |
||||||
|
- A `SCNetworkReachability` callback(s) is already in flight on thread Y |
||||||
|
|
||||||
|
#### Retain Cycle |
||||||
|
|
||||||
|
If we pass `Reachability` to CoreFoundtion while also providing retain/ |
||||||
|
release callbacks, we would create a retain cycle once CoreFoundation |
||||||
|
retains our `Reachability` class. This fixes the crashes and his how |
||||||
|
CoreFoundation expects the API to be used, but doesn't play nicely with |
||||||
|
Swift/ARC. This cycle would only be broken after manually calling |
||||||
|
`stopNotifier()` — `deinit` would never be called. |
||||||
|
|
||||||
|
#### ReachabilityWeakifier |
||||||
|
|
||||||
|
By providing both retain/release callbacks and wrapping `Reachability` in |
||||||
|
a weak wrapper, we: |
||||||
|
- interact correctly with CoreFoundation, thereby avoiding a crash. |
||||||
|
See "Memory Management Programming Guide for Core Foundation". |
||||||
|
- don't alter the public API of `Reachability.swift` in any way |
||||||
|
- still allow for automatic stopping of the notifier on `deinit`. |
