package cohttp-lwt-unix

v2.4.0 (2019-11-08)

• mirage: adapt to new mirage interfaces: mirage-flow 2.0.0, mirage-channel 4.0.0, mirage-kv 3.0.0 (#678 @hannesm)

• async: use Pipe.singleton instead of Pipe.of_list as it is more efficient (#677 @smuenzel-js)

v2.3.0 (2019-08-18)

• use conduit-mirage instead of mirage-conduit, which was renamed upstream in conduit. The minimum OCaml version supported for conduit-mirage is now OCaml 4.07 and higher. (#672 @avsm)

• remove deprecation warnings in OCaml 4.08.0 using stdlib-shims (#672 @avsm)

• async: do not read body if none is present (#671 @emillon)

v2.2.0 (2019-07-20)

• Previously if the client closed the connection while cohttp was handling a request, the server would crash (by default, unless the user overrode that using on_exn or changing Lwt's async exception handler). Now, cohttp will just log this at info level and continue. Exceptions produced by user code are logged as errors, while other exceptions generated by cohttp call back to the conduit exception handler, as before. (#669 @talex5)

v2.1.3 (2019-07-12)

• support uri.3.0.0 that has optional sexp support (#668 @avsm)

• use re.1.9.0 api to remove deprecation warnings (#664 @vbmithr)

v2.1.2 (2019-04-09)

• cohttp: handle empty cookie components gracefully without raising an exception (#663 @martinslota)

v2.1.1 (2019-04-05)

• cohttp-mirage: remove dependency on the result module (#662 @hannesm)

v2.1.0 (2019-03-01)

• cohttp-mirage: update to the newest Mirage_kv.RO API

v2.0.0 (2019-02-04)

Compatibility breaking interface changes:

Async: Expert response action no longer writes empty HTTP body (#647 by @andreas)

In cohttp.0.99, a number of subpackages were turned into explicit opam packages to simplify dependency management. To aid migration, some compatability shims were left in place so that the old findlib names would continue to work. They have now been removed as of this release. If you were still using them, then please rename them as follows:

• cohttp.lwt-core -> cohttp-lwt

• cohttp.lwt -> cohttp-lwt-unix

• cohttp.js -> cohttp-lwt-jsoo

• cohttp.async -> cohttp-async

• cohttp.top -> cohttp-top

• Remove use of deprecated Lwt_logs (#609 by @raphael-proust)

• Do not rely on locale for printing qvalues (#611 by @vbmithr)

• Ppx dependencies aren't just build time dependencies (#625 by @rgrinberg)

v1.1.0 (2018-03-28)

• Add an "expert mode" to hand off raw responses to a custom handler, which in turns makes protocols like Websockets easier (#488 by @msaffer).

• Set the user-agent by default if one is not provided (#586 by @TheCBaH).

• Fix typo in the cohttp.js META file.

• Refresh use of the Re library to the latest version (#602 by @rgrinberg).

• fix compatibility with OCaml 4.06 and -safe-string (#580, #581)

v0.99.0 (2017-07-12)

Port build to jbuilder, and break up OPAM packages into multiple independent packages instead of being optional dependencies against the main cohttp package. This makes it significantly easier to depend on precisely the libraries you need, but requires porting applications to use the new ocamlfind and opam scheme.

The new package layout is:

• cohttp: the main Cohttp module

• cohttp-lwt: the portable Lwt implementation

• cohttp-lwt-unix: the Lwt/Unix implementation

• cohttp-lwt-jsoo: the js-of-ocaml JavaScript implementation

• cohttp-async: the Jane Street Async implementation

• mirage-http: the MirageOS compatible implementation

• cohttp-top: a toplevel printer for the Cohttp types.

In each of these packages, the opam and ocamlfind package names are now the same, so you will need to rename the former subpackages such as cohttp.async to cohttp-async. The implementation is otherwise the same, so no other code changes should be required.

In return for these breaking changes to the packaging, it is now significantly easier to depend on a particular backend, also for us to rev the interfaces towards a stable 1.0 release. Jbuilder also builds the source tree around 4x faster than it did previously.

A number of deprecation warnings have been added to the source tree as well to mark the interfaces that will be removed in 1.0. These are Cohttp_lwt.{Client,Server,Net}, and a Cohttp_lwt.Body alias was added to deprecate the direct use of Cohttp_lwt_body. This will let us unify the namespaces of all the packages to use a single top-level module for each package in the future.

Most of the release and packaging work here was done by @rgrinberg and @avsm.

• Use the magic-mime library to add a MIME type by probing filename during static serving in the Lwt/Async backends. (#260)

• Add Cohttp.Header.add_opt_unless_exists to set a header only if an override wasn't supplied, and to initialise a fresh Header value if none is present.

• Do not override user-supplied headers in post_form or redirect.

• Request.make does not inject a transfer-encoding header if there is no body present in the request (#246).

• Expose IO.ic and IO.oc types for Cohttp_async (#271).

• Skip empty body chunks in Transfer_io.write (#270).

• With the Lwt backend, read hangs if trying to fetch more than Sys.max_string_length (which can be triggered on 32-bit platforms). Read only a maximum that fits into a string (#282).

• cohttp-curl-lwt now takes http method as parameter (#288)

• Fix installation of server binaries in OPAM metadata. (#295)

0.15.2 (2015-02-15):

• Lwt 2.4.7 renamed blit_bytes_string to blit_to_bytes, so depend on the newer API now. (#230)

• Use cmdliner in all of the Lwt client and server binaries. This gives cohttp-lwt-server a nice Unix-like command-line interface now that can be viewed with the --help option. (#218 via Runhang Li)

• Improve oasis constraints and regenerate opam file (#229 via Christophe Troestler).

0.15.0 (2014-12-24):

Compatibility breaking interface changes:

• Improve ocamldoc of Cohttp.S signature (#221).

0.14.0 (2014-12-18):

Compatibility breaking interface changes:

• Simplify the Lwt server signature, so that manual construction of a callback is no longer required (#210). Code that previous looked like:

   let conn_closed (_,conn_id) () = <...>
   let config = { Server.callback; conn_closed } in

should now be:

   let conn_closed (_,conn_id) = <...>
   let config = Server.make ~callback ~conn_closed () in

Compatibility breaking interface changes:

• Add sexp converters for Conduit contexts and Lwt client and server modules and module types.

New features and bug fixes:

• Can use the Conduit 0.7+ CONDUIT_TLS=native environment variable to make HTTPS requests using the pure OCaml TLS stack instead of depending on OpenSSL bindings. All of the installed binaries (client and server) can work in this mode.

• Add Cohttp_lwt_unix_debug which lets libraries control the debugging output from Cohttp. Previously the only way to do this was to set the COHTTP_DEBUG environment variable at the program start.

• Add cohttp-curl-lwt as a lightweight URI fetcher from the command-line. It uses the cmdliner as a new dependency.

• Remove build dependency check on lwt.ssl for cohttp.lwt. This has been moved to conduit, so only lwt.unix is needed here now.

0.12.0 (2014-11-07):

Compatibility breaking interface changes:

• Rename Cohttp.Auth.t to Cohttp.Auth.credential and Cohttp.Auth.req to Cohttp.Auth.challenge. Also expose an Other variant to make it more extensible for unknown authentication types. The Cohttp.Auth functions using these types have also been renamed accordingly.

• Rename Cohttp.Transfer.encoding_to_string to string_of_encoding for consistency with the rest of Cohttp's APIs.

• The has_body function in the Request and Response modules now explicitly signals when the body size is unknown.

• Move all the module type signatures into Cohttp.S.

• If users have percent-encoded file names, their resolution is changed: resolve_local_file in Cohttp_async and Cohttp_lwt now always percent-decode paths (#157)

• Remove the Cohttp_lwt.Server.server type synonym to t.

• When reading data from a HTTP body stream using the Fixed encoding, we need to maintain state (bytes remaining) so we know when to finish. The Cohttp.Request and Cohttp.Response interfaces now expose a reader and writer types to track this safely.

• Add is_empty function to the Cohttp.S.Body module type.

• Add Strings representation to Cohttp.Body to efficiently hold a list of body chunks.

• Move flushing logic for HTTP bodies into the portable Request and Response modules instead of individual Lwt and Async backends.

• Port module interfaces to the latest Conduit (0.6.0+) API.

• Cohttp requires OCaml 4.01.0 or higher now.

New features and bugfixes:

• Add a Cohttp_lwt_xhr JavaScript backend that enables Cohttp logic to be mapped to XMLHTTPRequest in browsers via js_of_ocaml (via Andy Ray).

• Add a Cohttp.String_io and String_io_lwt module that uses OCaml string or Buffer.t to read and write HTTP requests and responses instead of network connections.

• cohttp_server_lwt and cohttp_server_async now return better errors (#158)

• cohttp_server_lwt and cohttp_server_async now serve indexes directly (#162)

• [lwt] Add stop thread to terminate a running server if it finishes (#147).

• Add Body.map and Body.as_pipe to work with HTTP bodies more easily.

• Remove link-time dependency on camlp4 via META fixes (#127).

• Support HTTP methods and versions other than the standard ones. (#142).

• Improve cohttp_server_lwt and cohttp_server_async directory listings (#158)

0.11.2 (2014-04-21)

• Fix build by add a missing build-deps in _oasis.

0.11.1 (2014-04-17):

• Remove an errant async_ssl reference left in the _oasis file that is now handled by the Conduit library (#116).

• Add an Lwt-based SimpleHTTPServer equivalent as cohttp-server-lwt (#108).

• Cohttp.Connection.t now exposes sexp accessor functions (#117).

0.11.0 (2014-04-01):

• Remove dependency on ocaml-re in order to make library POSIX thread-safe.

• Shift most of the connection handling logic out to a Conduit library that worries about which SSL library to use, and fails if SSL is not available.

• Add Async-SSL support for both client and server (#102).

• Add Lwt-SSL support for the server side (the client side existed before).

• Fix buggy Async chunked POST handling.

0.10.0 (2014-03-02):

• Interface change: The Request and Response module types now explicitly signal Eof and Invalid (for errors), to help the backend distinguish them.

• Interface change: Unify HTTP body handling across backends into a Cohttp.Body module. This is extended by Async/Lwt implementations with their specific ways of handling bodies (Pipes for Async, or Lwt_stream for Lwt).

• [lwt] Interface change: HTTP client calls now raise Lwt exceptions rather than return an option type. This permits better error handling in Lwt.

• [lwt] Interface change: The Server callback now always provides a body argument, since Cohttp_lwt_body now explicitly supports empty bodys.

• Add Cohttp.Header.is_keep_alive to test if a connection should be reused.

• [lwt] Respect the keep-alive header in the server request handling.

• [async] Add a Body that takes a Pipe or a string, similarly to Lwt.

• Install cohttp-server binary even if tests are disabled.

• Begin an examples directory with some simple uses of the library.

0.9.16 (2014-01-30):

• Add sexp converters to most Cohttp types (#83).

• Improve Travis tests to cover more upstream users of Cohttp.

• Refactor build flags to let the portable Lwt-core be built independently of Lwt.unix.

• Add Merin editor file (#41).

0.9.11 (2013-10-27):

• Request module: When sending a request, add the port information in the host header field if available.

• Request module: When parsing a request, add scheme, host and port information in the uri.

• Add set-cookie header extraction functions for clients that read cookies.

• Explicitly flush the debug output when the COHTTP_DEBUG env variable is set.

• [async] Add client head/post/patch/delete methods.

• [lwt] Client.head no longer returns a response body, just the metadata.

• [lwt] Do not send chunked encoding headers with GET/DELETE requests that have no body.

0.9.9 (2013-06-12):

0.9.8 (2013-05-24):

• Lwt interface change: Rewrite Lwt backends to share code, and remove duplicate function calls from Uri.

• Depend on Uri 1.3.8+ as it exposes the parameter query functions now removed from Request.

• Add an Async.Server interface, and revise the Client interface to be more in line with Core standards.

• Add 422 Unprocessable Entity code.

• Refactor modules better across Lwt/Async, but incompatible with earlier releases for Async (Lwt is unchanged at present).
