* Regression guard for the fork-child Redis isolation fix (#1445).

|
|
*
|

|
|
* The per-message fork child must disconnect EVERY configured Redis connection
|
||
|
|
* it inherited from the parent — a single missed connection re-opens the predis
|
||
|
|
* desync flood ("unserialize(): Error at offset 0 of N bytes"). This pins that
|
||
|
|
* resetInheritedConnectionsInChild() disconnects each real connection and skips
|
||
|
|
* the non-connection config entries (client / options / anything host-less).
