h1. small todo list
* workers
** out-of-fd handling should be (only) in the main worker
* implement stat-caching with extra threads
* add per plugin+virtual-request specific data
* accesslog
* physical.* conditionals
* regexp support
* ipv6 support
* angel
** zero downtime restarts
** fd passing
** backend spawning with different uid/gid
** log rotation (or use the zero downtime restart?)
* throttling
** each connection gets a "magazine" that represents the amount of bytes it can send at the moment
** when sending data, decrease the magazine
** if magazine reaches 0, remove EV_WRITE for the sockwatcher and put connection at the end of the throttling queue
** each N milliseconds (maybe 500, configure via setup?), check if there are waiting connections in the queue and rearm if waiting for > N ms
** when rearming a connection, add number of allowed bytes to the magazine and set EV_WRITE again
** add throttling via "pools". all connections in a specific pool share a magazine which enables throttling of all connections in a vhost for example
** add throttling by ip (somewhat more complex)
* log
** scheme:// prefix
** write logs directly out in startup phase
* server-status overview
** if server.max-keepalive-idle can be set for host/url/filetypes/<whatever> show the last request in keep-alive state to make it visible where the client entered that state and maybe show sth. like 23/120, client entered that state 23s ago, will idle away after a total of 120s
* implement better counter_format(): allow output like "10 961 KiB"
* find good hashing algorithms for ipv6 and memory addresses
* add mechanism to store plugin data specific to client ip address. can be used for bandwidth throttling, limit requests per second, limit concurrent requests etc
** what would be the fastest algorithm for this task? hashtable, some kind of tree (red-black?) etc
** a lot of inserts, deletes and lookups
** has to be shared among all workers so locking needed
