drool/CHANGES

2021-07-16 Jerry Lundström

    Release 2.0.0

    This major release is a complete rewrite of drool to Lua using dnsjit!

    This includes two commands:
    - `drool replay`: replay DNS traffic from packet capture (PCAP) files
      and send it to a specified server, with options such as to manipulate
      the timing between packets, as well as loop packets infinitely or for
      a set number of iterations.
    - `drool respdiff`: replay DNS queries found in the PCAP, but only if
      a correlating response is also found. The query, original response
      and the received response is then stored into a LMDB database which
      can then be used by respdiff by CZ.NIC (see https://gitlab.labs.nic.cz/knot/respdiff)
      for analysis.

    See `man drool`, `man drool reply` and `man drool respdiff` for more
    information.

    Release 1.1.0

    Rework of the timing code to make it more effective, based on
    proof-of-concept from Petr Špaček @pspacek (CZ.NIC).

    The `best_effort` timing mode is now deprecated, this is now the same
    mode as `keep` and the warnings `keep` made when unable to follow
    timings have been removed.

    Release 1.0.1 (v1.0)

    Thanks to a few people, especially Petr Špaček @pspacek (CZ.NIC), for
    testing and reporting issues and other oddities (documentation is hard),
    release v1.0 is now ready!

    Increase of version because of how distributions compare package versions.

    Release 1.0.0-rc.1

    Mostly documentation updates and clarifications but also a new timing
    mode `best_effort` to send packets as fast as possible without warnings
    and a correct usage of `nanosleep()` on systems that does not support
    `clock_nanosleep()`.

2017-03-02 Jerry Lundström

    Release 1.0.0-alpha.3

    Reworked some of the client code to better handle stream sockets (TCP),
    retrys to send query if the system's sockets are exhausted.  Can send
    queries as the original protocol or force them into UDP or TCP.

    Default number of client pools running per context is now 1, increase
    this if you want to push UDP queries.  For TCP this has little effect
    since you will most likely hit system limits before that.

    Config changes:
    - Added `context client_pools num;`
    - Added `client_pool max_reuse_clients num;`
    - Added `client_pool sendas what;`

    Other changes:
    - Add timing details to warning about not keeping up with timings

    f8805da TCP, send as, proper shutdown

    cae9834 Honor previous fd flags

2017-02-21 Jerry Lundström

    Release 1.0.0-alpha.2

    This release implements the core engine and most of the network code
    which consists of:
    - parsing DNS packet from input using omg-dns
    - sending queries to a client pool using sllq
    - processing queries using client objects and libev event loops

    Handling results/responses have yet been implemented.

    Command line option changes:
    - Added `-R` to specify read mode for PCAP files
    - Removed `-w` and `-o`

    Config changes:
    - Added `timing ignore;`
    - Added `timing keep;`
    - Added `timing add nanoseconds;`
    - Added `timing reduce nanoseconds;`
    - Added `timing multiply float;`, note: no logic added yet
    - Added `client_pool target "ip" "port";`
    - Added `client_pool max_clients num;`
    - Added `client_pool client_ttl float;`
    - Added `client_pool skip_reply;`
    - Removed `read`, `input`, `write` and `output`
