Subject: [PATCH] data: don't send change updates for login-history
|
|
|
e33294 |
|
|
|
e33294 |
The login-history property of user objects can be quite large.
|
|
|
e33294 |
If wtmp is changed frequently, that can lead to memory fragmentation
|
|
|
e33294 |
in clients.
|
|
|
e33294 |
|
|
|
e33294 |
Furthermore, most clients never check login-history, so it's
|
|
|
e33294 |
wasted memory and wasted cpu.
|
|
|
e33294 |
|
|
|
e33294 |
This commit disables change notification for that property. If
|
|
|
e33294 |
a client really needs to get updates, they can manually refresh
|
|
|
e33294 |
their cache when appropriate.
