small todo list¶

Note: this list is updated every now and then and doesn't necessarily represent the exact state of development. Use it as a rough overview.

• core
  • out-of-fd handling should be (only) in the main worker
  • throttling by ip
  • X-Throttle ?
  • limit request/response header size, request url length
  • listen to unix sockets
  • config parser cleanup
  • option for directory of upload tempfiles

• angel
  • log rotation (or use the zero downtime restart?)
  • control socket interface
  • angel-control util

• log
  • scheme:// prefix
  • support for pipes
  • open log files with angel
  • print "startup" (== if logging is disabled) log messages to stderr/angel if the log level target isn't /dev/null

• plugin api
  • inter-plugin api
  • plugin data per client ip address
    • can be used for bandwidth throttling, limit requests per second, limit concurrent requests etc
    • has to be shared among all workers so locking needed?
    • maybe let main worker do the lookup/removal in a radix tree so no locking needed for that and let plugin make sure it's threadsafe when modifying

• modules
  • port remaining modules from 1.x
    • mod_evasive
    • mod_extforward
    • mod_uploadprogress
    • mod_ssi ?
    • mod_ajp13 ?
    • mod_trigger_b4_dl ?
    • mod_userdir ?
    • mod_usertrack ?
    • mod_(web)dav ?
  • new concept for:
    • mod_{my,pg}sql_vhost (load complete config instead of just doc-root)
    • mod_rrdtool
  • lua plugins for:
    • mod_flv_streaming
  • sql vhost (lua handler go generate actions from db rows?)
  • add even more innovative modules :)

• mod_status
  • show timeout in duration column like "5/120" ?

• mod_dirlist
  • generate stat dirlist/html body async (to allow etag-cache-hit)

• mod_openssl
  • sni support
  • user certs?

• mod_deflate
  • add some options: buffer size, minimum-file-size, compression parameters, select allowed methods

• stat-cache:
  • revalidate dirlist entries with stat() after cache hit ?
  • purge invalid entries (stat()/open() failed), i.e. remove from hash tables
  • check for normal stat entry, stat() and S_ISDIR before queuing dirlist job
  • reset ttl after revalidating entries
  • limit for hash tables?
  • check symlink/symlink-if-owner-match

• test framework

• build systems
  • use shared libraries for common libs
  • lighty common libs should probably installed in a default lib directory (/usr/lib), plugins in a subdir
  • provide pkg-config for 3rd party module builds
  • at least one build system should provide static builds
