| Medium-long term wish list - 2016/11/25 |
| |
| Legend: '+' = done, '-' = todo, '*' = done except doc |
| |
| 1.8 or later : |
| - return-html code xxx [ file "xxx" | text "xxx" ] if <acl> |
| |
| - return-raw [ file "xxx" | text "xxx" ] if <acl> |
| |
| - have multi-criteria analysers which subscribe to req flags, rsp flags, and |
| stream interface changes. This would result in a single analyser to wait |
| for the end of data transfer in HTTP. |
| |
| - support for time-ordered priority queues with ability to add an offset |
| based on request matching. Each session will have one ebtree node to be |
| attached to whatever queue the session is waiting in. |
| |
| - make it possible to condition a timeout on an ACL (dynamic timeouts) |
| |
| - forwardfor/originalto except with IPv6 |
| |
| - remove lots of remaining Alert() calls or ensure that they forward to |
| send_log() after the fork. |
| |
| - tcp-request session expect-proxy {L4|L5} if ... |
| |
| - wait on resource (time, mem, CPU, socket, server's conn, server's rate, ...) |
| |
| - bandwidth limits |
| |
| - buddy servers to build defined lists of failovers. Detect loops during |
| the config check. |
| |
| server XXX buddy YYY |
| server YYY # may replace XXX when XXX fails |
| |
| - spare servers : servers which are used in LB only when a minimum farm |
| weight threshold is not satisfied anymore. Useful for inter-site LB with |
| local pref by default. |
| |
| - add support for event-triggered epoll, and maybe change all events handling |
| to pass through an event cache to handle temporarily disabled events. |
| |
| - evaluate the changes required for multi-process+shared mem or multi-thread |
| +thread-local+fast locking. |
| |
| Old, maybe obsolete points : |
| - clarify licence by adding a 'MODULE_LICENCE("GPL")' or something equivalent. |
| |
| - 3 memory models : failsafe (prealloc), normal (current), optimal (alloc on |
| demand) |
| |
| - implement support for event-triggerred epoll() |
| |
| - verify if it would be worth implementing an epoll_ctl_batch() for Linux |
| |
| - option minservers XXX : activates some spare servers when active servers |
| are insufficient |
| |
| - initcwnd parameter for bind sockets : needed in kernel first |
| |
| - have a callback function which would be called after a server is selected, |
| for header post-processing. That would be mainly used to remove then add |
| the server's name or cookie in a header so that the server knows it. |
| |
| Unsorted : |
| - outgoing log load-balancing (round-robin or hash among multiple servers) |
| |
| - internal socket for "server XXX frontend:name" |
| |
| - HTTP/2.0 |
| |
| - XML inspection (content-switching for SOAP requests) |
| |
| - random cookie generator |
| |
| - fastcgi to servers |
| |
| - hot config reload |
| |
| - RAM-based cache for small files |
| |
| - RHI - BGP |
| |
| - telnet/SSH cli |
| |
| - dynamic memory allocation |
| |
| - dynamic weights based on check response headers and traffic response time |
| |
| - various kernel-level acceleration (multi-accept, ssplice, epoll2...) |
