Dune Dependency





v0.2.6 (2024-01-06)

  • Call shutdown in h2 to properly close http2 connections. This fixes a file descriptor leak reported in #22 (#23, @reynir @hannesm)

v0.2.5 (2023-07-05)

  • Order http2 headers appropriately to avoid malformed requests (#20, @hannesm)

v0.2.4 (2023-07-03)

  • In HTTP/2, always lowercase the header keys (#19 by @ScoreUnder, fixes #7 by @kit-ty-kate)

v0.2.3 (2023-03-20)

  • Adapt to h2 0.10.0 API change (#18 by @hannesm)

v0.2.2 (2023-02-17)

  • Update to tls 0.16.0 package split: tls.lwt is now tls-lwt (#17 by @hannesm)

v0.2.1 (2023-01-02)

  • Fix ownership of buffers given by the HTTP scheduler (#16 by @dinosaure)

v0.2.0 (2022-11-03)

  • API: In the body function passed to request, the response is the first argument. This allows a client to do different stuff with the body, depending on the response code (and/or content type etc.) (#15 by @hannesm, reviewed and suggested by @reynir in

v0.1.0 (2022-10-25)

  • Add function "request", remove "one_request". The response body is a stream now to support responses where the body exceeds the memory (or maximum string length) (#14 @kit-ty-kate)

  • BUGFIX hurl had "input" and "output" switched (#14 @hannesm)

v0.0.8 (2022-09-17)

  • use Status.is_redirection instead of a match on the polymorphic variant, to support unknown 3xx codes (such as 308) (#11 @hannesm)

  • add some yield in the main loop to allow concurrency with other fibers (issue #12 by @kit-ty-kate, fixed in #13 by @dinosaure)

  • Add ?tls_config to Http_lwt_client.one_request to enable passing an entire TLS configuration

  • Avoid exception in resolve_location

  • Add ?happy_eyeballs to Http_lwt_client.one_request to allow reusing this state across requests

  • Initialize Ca_certs.authenticator only once (lazily) to avoid decoding trust anchors multiple times

  • Fix Http_lwt_unix.Buffer for resizing on put (to avoid errors with H2)

  • Avoid exceptions from Lwt.wakeup_later by calling it at most once

v0.0.3 (2021-09-07)

  • Provide the optional argument ?follow_redirect to not follow redirects

v0.0.2 (2021-09-06)
