Connecting to a remote host via IP version 4 or 6







v0.4.0 (2022-12-02)

  • Cancellation of connection attempts (#30 @reynir @hannesm, fixes #27)

  • Make the type id abstract (suggested by @reynir in #30)

  • Add reason for failures to the variants, improves log output (#30, fixes #7, @hannesm @reynir)

  • Remove log messages about DNS resolution success/failure when there is no
    awaiting connection (#30, @hannesm)

  • Use the domain name of the fist IP address in connect_ip as identifier (this
    provides more useful information than the hardcoded "host.invalid") (#29, @hannesm)

v0.3.1 (2022-11-21)

  • Improve documentation for Happy_eyeballs.timer (#24, #25 @reynir, review by @hannesm and @bikallem)

  • Demote log levels that are (likely) caused by missing cancellation (#26 @reynir)

v0.3.0 (2022-03-21)

  • Happy_eyeballs_mirage.connect_device: remove int64 argument (timestamp), use
    monotonic clocks C.elapsed_ns () instead (noticed by @dinosaure)

v0.2.0 (2022-03-16)

  • Happy_eyeballs_mirage: add a module type signature to allow creation of
    a MirageOS device (#22 @dinosaure)

  • happy-eyeballs-lwt: update to cmdliner 1.1.0 (@hannesm)

v0.1.3 (2022-01-12)

  • Happy_eyeballs.create: add v6_connect_timeout parameter - the amount of
    nanoseconds (default: 200ms) after which to attempt IPv4 connection
    establishment. (#21 @hannesm, review by @reynir, issue reported at
    roburio/http-lwt-client#8 by @kit-ty-kate)

  • Happy_eyeballs.create: add resolve_retries - the amount of resolve attempts
    when a (resolve) timeout occurs (default: 3). (#21 @hannesm, review by
    @reynir, issue reported at roburio/http-lwt-client#8 by @kit-ty-kate)

v0.1.2 (2021-12-17)

  • Happy_eyeballs_{lwt,mirage}: update to tcpip 7.0.0, remove mirage-stack
    dependency (#20 @dinosaure)

v0.1.1 (2021-11-18)

  • Happy_eyeballs_lwt.create and Happy_eyeballs_mirage.create now take an
    optional ?happy_eyeballs:Happy_eyeballs.t argument, and also an optional
    ?dns:Dns_client_lwt.t/DNS.t argument. This avoids the need to forward all
    potential creation arguments of Happy_eyeballs and DNS. (#19 @hannesm)

  • Fix state machine: if Connecting fails, and resolved is not yet both, return
    to Resolving (instead of Error) (#13 @hannesm,
    similar to d0d4ef5ea2aaf2de407ba84742c5648489c47e1f #9)

  • Add a state machine diagram (happy_eyeballs.dot) (#13 @hannesm)

v0.1.0 (2021-10-27)

  • Remove assertion in timer, and fix the code (reported by @dinosaure in #17,
    fix in #18 by @hannesm, reviewed by @reynir)

  • Support OCaml 4.08 (#18 hannesm, requested in #16 by @smorimoto)

v0.0.8 (2021-10-20)

  • Adapt to dns 6.0.0 API (#15 @hannesm)

  • Drop rresult dependency

  • Avoid deprecated fmt functions, require fmt 0.8.7

v0.0.7 (2021-09-28)

  • Document changes of the return value of timer (#11 @reynir)

  • Pass timeouts as duration into the create functions (#12 @hannesm)

v0.0.6 (2021-09-21)

  • return a variant from timer to indicate whether there are connections pending
    or the timer can be suspended -- this avoids unnecessary busy work (@reynir)

  • connect_ip: take list of Ipaddr.t and int pairs instead of separate lists.
    The reason for this change is the dns-client. (@hannesm @reynir)

v0.0.5 (2021-09-13)

  • connect_ip: take an optional shuffle argument and an ordered list of ips to
    attempt connections to. The reason for this change is that /etc/resolv.conf
    specifies an ordering. (@hannesm)

v0.0.4 (2021-09-11)

  • Use set from ipaddr (>= 5.2.0) instead providing these (@hannesm)

v0.0.3 (2021-09-07)

  • BUGFIX: Avoid exception if expand_list is called with an empty list (@hannesm)

v0.0.2 (2021-09-06)

  • BUGFIX: Delay connect failure if v6 resolution and connection attempt fails
    before v4 resolution had a chance to succeed or fail (issue #9). (@hannesm)

v0.0.1 (2021-08-24)

  • Initial release (@hannesm)
