mod_bookmarks2: Use same default as mod_pep for max_items
Should fix the issue with max items until the proper "max" can be used,
by following the configured max.
While "max" is already in trunk, it's not easily usable in 0.11.x
This limit and option was added to mod_pep in Prosody rev aefb96a52f5f

--- labels: - 'Stage-Beta' summary: 'Connection-level rate limiting' ... Introduction ============ On some servers, especially public ones, it is desired to make sure that everyone gets their fair share of system resources (and no more). mod\_limits allows you to specify traffic bandwidth limits, preventing any single connection hogging the server's CPU, RAM and bandwidth. Details ======= mod\_limits detects when a connection has exceeded its traffic allowance and temporarily ignores a connection. Due to the way TCP and the OS's network API works no data is lost, only slowed. Configuration ============= Currently mod\_limits is configured per connection type. The possible connection types are: - c2s - s2sin - s2sout - component The limits are specified like so in the **global** section of your config (they cannot be per-host): ``` {.lua} limits = { c2s = { rate = "3kb/s"; burst = "2s"; }; s2sin = { rate = "10kb/s"; burst = "5s"; }; } ``` All units are in terms of *bytes*, not *bits*, so that "kb/s" is interpreted as "kilobytes per second", where a kilobyte is 1000 bytes. Compatibility ============= ----- ------------------- 0.9 Works 0.8 Doesn't work(\*) ----- ------------------- (\*) This module can be made to work in 0.8 if you do two things: 1. Install [util.throttle](http://hg.prosody.im/0.9/raw-file/d46948d3018a/util/throttle.lua) into your Prosody source's util/ directory. 2. If you use libevent apply [this patch](http://prosody.im/patches/prosody08-mod-limits-fix.patch) to net/server\_event.lua.
