Medium-long term roadmap - 2010/04/10

|
1.5 (ETA 2010/12/31) :
|
|
- server-side HTTP keepalive
|
|
|
|
- return-html code xxx [ file "xxx" | text "xxx" ] if <acl>
|
|
|
|
- return-raw [ file "xxx" | text "xxx" ] if <acl>
|
|
|
|
- add support for client-side and server-side unix sockets
|
|
|
|
- try to remove srv==NULL internally and assign a dummy server to each backend
|
|
for dispatch, http_proxy and transparent modes.
|
|
|
|
- rename L4 acls as L6 ACLs when some content is involved
|
|
|
|
- add new L4 ACL checks immediately after accept, before even allocating the
|
|
buffers ("connection {accept|reject|delay|freeze} {if|unless}").
|
|
|
|
- implement support for "connection freeze" after accept. A list of frozen
|
|
connections should be maintained so that it is possible to recycle them
|
|
when new file descriptors are required.
|
|
|
|
- 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.
|
|
|
|
- assign a nice priority based on ACLs.
|
|
|
|
- pattern extraction is needed for ACLs and stickiness. It would work like
|
|
this :
|
|
|
|
acl <name> <pattern> [-i] <values>...
|
|
|
|
All ACL fetch method currently available would be transformed into pattern
|
|
extraction methods. That way we could stick on hdr(x-forwarded-for) or use
|
|
source 0.0.0.0 usesrc <pattern> (such as "hdr_ip(headername)"). Note that
|
|
ACLs sometimes need iterative matching/extraction.
|
|
|
|
- add support for complex pattern extraction rules :
|
|
|
|
pattern = <pattern_term>
|
|
| '{' pattern_expr '}'
|
|
|
|
pattern_expr = <pattern_term> [ <transform> ... ]
|
|
|
|
- support loading data sets from files
|
|
+ present/not present (eg: netmasks)
|
|
- pattern conversion per prefixes. Eg: convert src IP to country.
|
|
|
|
- make new patterns available based on stickiness matching :
|
|
- number of entries in table for the matched pattern
|
|
- same after having increased the match counter
|
|
|
|
- add support for concurrency match in tables
|
|
- just like stickiness, but counted per session (or request), increased
|
|
on first match and decreased at end of request or connection. This
|
|
requires that the session has a list of matched terms that must be
|
|
released at the end.
|
|
|
|
1.6 (will probably change anyway) :
|
|
- wait on resource (mem, socket, server's conn, server's rate, ...)
|
|
|
|
- bandwidth limits
|
|
|
|
- create internal services and make stats, CLI, etc... part of that.
|
|
|
|
- use_server ... if ...
|
|
|
|
- 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.
|
|
|
|
|
|
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)
|
|
|
|
- ability to assign a task priority based on L7 matching
|
|
|
|
- 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
|
|
|
|
- new keyword 'check' : check http xxx, check smtp xxx, check ssl-hello
|
