limitStorage: Change size of the message storage

Description

This function allows to change number of total size of the messages that are received via the websocket and are stored in the memory.

Usage

limitStorage(n = NULL, size = NULL)

Arguments

n

Number of messages that can be stored simultaneously.

size

Maxim total size of all stored messages in bytes.

Value

Current maximum size of the storage and maximum allowed number of stored messages.

Details

For security reasons, the control of the currently running R session is limited to calling only some user specified functions and reassigning some user specified variables. All other messages are stored in the memory and can be later processed by calling authorize function. To prevent overuse of memory, one can limit the size of the storage by number of messages or by their total size estimated by object.size. If the storage grows above the set limits, older messages are removed. The last received message will not be removed even if its takes more memory than is allowed by this function.

# NOT RUN {
limitStorage(n = 10)
limitStorage(size = 10 * 1024^2)
lim <- limitStorage()

# }
