Subject: [PATCH] Add system property to disable book size limits
|
|
|
|
If anyone comes in with a watchdog crash related to books after this patch
|
|
you will not only be publicly shamed but also made an example of.
|
|
|
|
Disables the security limits on books entirely, allowing plugins AND players
|
|
to make books with as much data as they want. Do not use this without
|
|
limiting incoming data from packets in some other way.
