Check TE header is server (bikallem mirage/ocaml-cohttp#941) - cohttp-eio: add User-Agent header to request from Client (bikallem mirage/ocaml-cohttp#940) - cohttp-eio: add Content-Length header to request/response (bikallem mirage/ocaml-cohttp#929) - cohttp-eio: add cohttp-eio client api - Cohttp_eio.Client (bikallem mirage/ocaml-cohttp#879) - http: add requires_content_length function for requests and responses (bikallem mirage/ocaml-cohttp#879) - cohttp-eio: use Eio.Buf_write and improve server API (talex5 mirage/ocaml-cohttp#887) - cohttp-eio: update to Eio 0.3 (talex5 mirage/ocaml-cohttp#886) - cohttp-eio: convert to Eio.Buf_read (talex5 mirage/ocaml-cohttp#882) - cohttp lwt client: Connection cache and explicit pipelining (madroach mirage/ocaml-cohttp#853) - http: add Http.Request.make and simplify Http.Response.make (bikallem mseri mirage/ocaml-cohttp#878) - http: add pretty printer functions (bikallem mirage/ocaml-cohttp#880) - New eio based client and server on top of the http library (bikallem mirage/ocaml-cohttp#857) - New curl based clients (rgrinberg mirage/ocaml-cohttp#813) + cohttp-curl-lwt for an Lwt backend + cohttp-curl-async for an Async backend - Completely new Parsing layers for servers (anuragsoni mirage/ocaml-cohttp#819) + Cohttp now uses an optimized parser for requests. + The new parser produces much less temporary buffers during read operations in servers. - Faster header comparison (gasche mirage/ocaml-cohttp#818) - Introduce http package containing common signatures and structures useful for compatibility with cohttp - and no dependencies (rgrinberg mirage/ocaml-cohttp#812) - async(server): allow reading number of active connections (anuragsoni mirage/ocaml-cohttp#809) - Various internal refactors (rgrinberg, mseri, mirage/ocaml-cohttp#802, mirage/ocaml-cohttp#812, mirage/ocaml-cohttp#820, mirage/ocaml-cohttp#800, mirage/ocaml-cohttp#799, mirage/ocaml-cohttp#797) - http (all cohttp server backends): Consider the connection header in response in addition to the request when deciding on whether to keep a connection alive (anuragsoni, mirage/ocaml-cohttp#843) + The user provided Response can contain a connection header. That header will also be considered in addition to the connection header in requests when deciding whether to use keep-alive. This allows a handler to decide to close a connection even if the client requested a keep-alive in the request. - async(server): allow creating a server without using conduit (anuragsoni mirage/ocaml-cohttp#839) + Add `Cohttp_async.Server.Expert.create` and `Cohttp_async.Server.Expert.create_with_response_action`that can be used to create a server without going through Conduit. This allows creating an async TCP server using the Tcp module from `Async_unix` and lets the user have more control over how the `Reader.t` and `Writer.t` are created. - http(header): faster `to_lines` and `to_frames` implementation (mseri mirage/ocaml-cohttp#847) - cohttp(cookies): use case-insensitive comparison to check for `set-cookies` (mseri mirage/ocaml-cohttp#858) - New lwt based server implementation: cohttp-server-lwt-unix + This new implementation does not depend on conduit and has a simpler and more flexible API - async: Adapt cohttp-curl-async to work with core_unix. - *Breaking changes* + refactor: move opam metadata to dune-project (rgrinberg mirage/ocaml-cohttp#811) + refactor: deprecate Cohttp_async.Io (rgrinberg mirage/ocaml-cohttp#807) + fix: move more internals to Private (rgrinberg mirage/ocaml-cohttp#806) + fix: deprecate transfer encoding field (rgrinberg mirage/ocaml-cohttp#805) + refactor: deprecate Cohttp_async.Body_raw (rgrinberg mirage/ocaml-cohttp#804) + fix: deprecate more aliases (rgrinberg mirage/ocaml-cohttp#803) + refactor: deprecate connection value(rgrinberg mirage/ocaml-cohttp#798) + refactor: deprecate using attributes (rgrinberg mirage/ocaml-cohttp#796) + cleanup: remove cohttp-{curl,server}-async (rgrinberg mirage/ocaml-cohttp#904) + cleanup: remove cohttp-{curl,server,proxy}-lwt (rgrinberg mirage/ocaml-cohttp#904) + fix: all parsers now follow the spec and require `\r\n` endings. Previously, the `\r` was optional. (rgrinberg, mirage/ocaml-cohttp#921) - `cohttp-lwt-jsoo`: do not instantiate `XMLHttpRequest` object on boot (mefyl mirage/ocaml-cohttp#922) ## v5.0.0 (2021-12-15) - Cohttp.Header: new implementation (lyrm mirage/ocaml-cohttp#747) + New implementation of Header modules using an associative list instead of a map, with one major semantic change (function ```get```, see below), and some new functions (```clean_dup```, ```get_multi_concat```) + More Alcotest tests as well as fuzzing tests for this particular module. ### Purpose The new header implementation uses an associative list instead of a map to represent headers and is focused on predictability and intuitivity: except for some specific and documented functions, the headers are always kept in transmission order, which makes debugging easier and is also important for [RFC7230§3.2.2](https://tools.ietf.org/html/rfc7230#section-3.2.2) that states that multiple values of a header must be kept in order. Also, to get an intuitive function behaviour, no extra work to enforce RFCs is done by the basic functions. For example, RFC7230§3.2.2 requires that a sender does not send multiple values for a non list-value header. This particular rule could require the ```Header.add``` function to remove previous values of non-list-value headers, which means some changes of the headers would be out of control of the user. With the current implementation, an user has to actively call dedicated functions to enforce such RFCs (here ```Header.clean_dup```). ### Semantic changes Two functions have a semantic change : ```get``` and ```update```. #### get ```get``` was previously doing more than just returns the value associated to a key; it was also checking if the searched header could have multiple values: if not, the last value associated to the header was returned; otherwise, all the associated values were concatenated and returned. This semantics does not match the global idea behind the new header implementation, and would also be very inefficient. + The new ```get``` function only returns the last value associated to the searched header. + ```get_multi_concat``` function has been added to get a result similar to the previous ```get``` function. #### update ```update``` is a pretty new function (mirage/ocaml-cohttp#703) and changes are minor and related to ```get``` semantic changes. + ```update h k f``` is now modifying only the last occurrences of the header ```k``` instead of all its occurrences. + a new function ```update_all``` function has been added and work on all the occurrences of the updated header. ### New functions : + ```clean_dup``` enables the user to clean headers that follows the {{:https://tools.ietf.org/html/rfc7230#section-3.2.2} RFC7230§3.2.2} (no duplicate, except ```set-cookie```) + ```get_multi_concat``` has been added to get a result similar to the previous ```get``` function. - Cohttp.Header: performance improvement (mseri, anuragsoni mirage/ocaml-cohttp#778) **Breaking** the headers are no-longer lowercased when parsed, the headers key comparison is case insensitive instead. - cohttp-lwt-unix: Adopt ocaml-conduit 5.0.0 (smorimoto mirage/ocaml-cohttp#787) **Breaking** `Conduit_lwt_unix.connect`'s `ctx` param type changed from `ctx` to `ctx Lazy.t` - cohttp-mirage: fix deprecated fmt usage (tmcgilchrist mirage/ocaml-cohttp#783) - lwt_jsoo: Use logs for the warnings and document it (mseri mirage/ocaml-cohttp#776) - lwt: Use logs to warn users about leaked bodies and document it (mseri mirage/ocaml-cohttp#771) - lwt, lwt_unix: Improve use of logs and the documentation, fix bug in the Debug.enable_debug function (mseri mirage/ocaml-cohttp#772) - lwt_jsoo: Fix exception on connection errors in chrome (mefyl mirage/ocaml-cohttp#761) - lwt_jsoo: Fix `Lwt.wakeup_exn` `Invalid_arg` exception when a js stack overflow happens in the XHR completion handler (mefyl mirage/ocaml-cohttp#762). - lwt_jsoo: Add test suite (mefyl mirage/ocaml-cohttp#764). ## v4.0.0 (2021-03-24) - cohttp.response: fix malformed status header for custom status codes (mseri aalekseyev mirage/ocaml-cohttp#752) - remove dependency to base (samoht mirage/ocaml-cohttp#745) - add GitHub Actions workflow (smorimoto mirage/ocaml-cohttp#739) - `cohttp-lwt-jsoo`: Forward exceptions to caller when response is null (mefyl mirage/ocaml-cohttp#738) - Use implicit executable dependency for generate.exe (TheLortex mirage/ocaml-cohttp#735) - cohttp: fix chunked encoding of empty body (mefyl mirage/ocaml-cohttp#715) - cohttp-async: fix body not being uploaded with unchunked Async.Pipe (mefyl mirage/ocaml-cohttp#706) - cohttp-{async, lwt}: fix surprising behaviours of Body.is_empty (anuragsoni mirage/ocaml-cohttp#714 mirage/ocaml-cohttp#712 mirage/ocaml-cohttp#713) - refactoring of tests (mseri mirage/ocaml-cohttp#709, dinosaure mirage/ocaml-cohttp#692) - update documentation (dinosaure mirage/ocaml-cohttp#716, mseri mirage/ocaml-cohttp#720) - fix deadlock in logging (dinosaure mirage/ocaml-cohttp#722) - improve media type parsing (seliopou mirage/ocaml-cohttp#542, dinosaure mirage/ocaml-cohttp#725) - [reverted] breaking changes to client and server API to use conduit 3.0.0 (dinosaure mirage/ocaml-cohttp#692). However, as the design discussion did not reach consensus, these changes were reverted to preserve better compatibility with existing cohttp users. (samoht mirage/ocaml-cohttp#741) **Potentially breaking changes** - remove `wrapped false` from the codebase (rgrinberg mirage/ocaml-cohttp#734) - cohttp: add Uri.scheme to Request.t (brendanlong mirage/ocaml-cohttp#707) - cohttp: update HTTP codes (emillon mirage/ocaml-cohttp#711) - cohttp-lwt-jsoo: rename Cohttp_lwt_xhr to Cohttp_lwt_jsoo for consistency (mseri mirage/ocaml-cohttp#717) - cohttp: fix transfer-encoding ordering in headers (mseri mirage/ocaml-cohttp#721) - lower-level support for long-running cohttp-async connections (brendanlong mirage/ocaml-cohttp#704) - add of_form and to_form functions to body (seliopou mirage/ocaml-cohttp#440, mseri mirage/ocaml-cohttp#723) - cohttp-lwt: partly inline read_response, fix body stream leak (madroach dinosaure mirage/ocaml-cohttp#696). Note: there is a new warning that may show up in your logs when bodies are leaked, see also [mirage/ocaml-cohttp#730](mirage/ocaml-cohttp#730). - add comparison functions for Request.t and Response.t via ppx_compare (msaffer-js dinosaure mirage/ocaml-cohttp#686) ## v3.0.0 - aborted ## v2.5.5 (2021-03-15) - `Cohttp_async.resolve_local_file`, `Cohttp_lwt.resolve_local_file` and `Cohttp_lwt_unix.resolve_file` are now the same code under the hood (`Cohttp.Path.resolve_local_file`). The old names have been preserved for compatibility, but will be marked as deprecated in the next release. This changes the behavior of `Cohttp_lwt_unix.resolve_file`: it now percent-decodes the paths and blocks escaping from the docroot correctly. This also fixes and tests the corner cases in these methods when the docroot is empty. (ewanmellor mirage/ocaml-cohttp#755) ## v2.5.4 (2020-07-21) - cohttp: a change in mirage/ocaml-cohttp#694 modified the semantics of Header.replace. The semantics change is reverted, and a new Header.update function is introduced, following the semantics of Map.update. (mirage/ocaml-cohttp#702 mseri) - cohttp: reimplement update to support compilers that are older than OCaml 4.06 (mirage/ocaml-cohttp#703 mseri) ## v2.5.3 (2020-06-27) - cohttp-async: adapt to async >= v0.14 (mirage/ocaml-cohttp#699 copy) ## v2.5.2 (2020-06-27) - cohttp, cohttp-async: correctly set host header for unix domain sockets, implement Unix domain socket support for cohttp-async (mirage/ocaml-cohttp#698 Leonidas-from-XIV) - cohttp: better body encoding management when creating request and response, and correction of Header.replace function (mirage/ocaml-cohttp#694 lyrm) ## v2.5.1 (2020-02-18) - cohttp-lwt: pass ctx through HEAD client requests (mirage/ocaml-cohttp#689 hannesm) ## v2.5.0 (2019-12-17) - cohttp-async: support async v0.13.0 (mirage/ocaml-cohttp#680 copy) - cohttp-lwt-jsoo: support js_of_ocaml 3.5.0 and higher (avsm) ## 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 (mirage/ocaml-cohttp#678 hannesm) - async: use Pipe.singleton instead of Pipe.of_list as it is more efficient (mirage/ocaml-cohttp#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. (mirage/ocaml-cohttp#672 avsm) - remove deprecation warnings in OCaml 4.08.0 using stdlib-shims (mirage/ocaml-cohttp#672 avsm) - async: do not read body if none is present (mirage/ocaml-cohttp#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. (mirage/ocaml-cohttp#669 talex5) ## v2.1.3 (2019-07-12) - support uri.3.0.0 that has optional sexp support (mirage/ocaml-cohttp#668 avsm) - use re.1.9.0 api to remove deprecation warnings (mirage/ocaml-cohttp#664 vbmithr) ## v2.1.2 (2019-04-09) - cohttp: handle empty cookie components gracefully without raising an exception (mirage/ocaml-cohttp#663 martinslota) ## v2.1.1 (2019-04-05) - `cohttp-mirage`: remove dependency on the `result` module (mirage/ocaml-cohttp#662 hannesm) - Support Async v0.12.0 and higher (mirage/ocaml-cohttp#661 copy) ## 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 (mirage/ocaml-cohttp#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 compatibility 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` Other changes and bugfixes: * Lwt, Mirage: Add log warnings for uncaught exceptions (mirage/ocaml-cohttp#592 by ansiwen) * Log invalid client input and do not catch out of memory exceptions (mirage/ocaml-cohttp#652 hannesm) * Port opam files to opam2 and add local synopsis and descriptions. * Lwt: Add Expert response action for servers (mirage/ocaml-cohttp#647 by andreas) * Use the namespaced `js_of_ocaml` interfaces from 3.3.0 onwards (mirage/ocaml-cohttp#654 avsm) * Use Base64 3.1.0 interfaces (mirage/ocaml-cohttp#655 avsm) * Clean up redundant conflicts in the `opam` files (avsm) ## v1.2.0 (2018-10-19) * Support more than a single chunk extension for RFC7320 compliance (mirage/ocaml-cohttp#618 by djs55) * Lwt-unix: add a `?backlog` argument to the serve function (samoht) * Use the uri.2.0.0 interfaces for sexpression generation of types (avsm) * Switch to `sexplib0` for a more lightweight s-expression library (mseri) * Minimum OCaml compiler version requirement is now 4.04.1 (mseri) * Add an example of using custom resolvers to the README (mseri) ## v1.1.1 (2018-08-13) * Update to be compatible with new async/core (mirage/ocaml-cohttp#607 by rgrinberg) * Remove use of deprecated `Lwt_logs` (mirage/ocaml-cohttp#609 by raphael-proust) * Do not rely on locale for printing qvalues (mirage/ocaml-cohttp#611 by vbmithr) * Ppx dependencies aren't just build time dependencies (mirage/ocaml-cohttp#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 (mirage/ocaml-cohttp#488 by msaffer). * Set the user-agent by default if one is not provided (mirage/ocaml-cohttp#586 by TheCBaH). * Fix typo in the `cohttp.js` META file. * Refresh use of the Re library to the latest version (mirage/ocaml-cohttp#602 by rgrinberg). * Rearrange the ppx dependencies to be more specific (mirage/ocaml-cohttp#596 by yomimono). * Explicitly depend on sexplib in the Async backend (mirage/ocaml-cohttp#605 by kevinqiu). ## v1.0.2 (2018-01-06) * Support Async v0.10.0 and OCaml 4.06.0 (mirage/ocaml-cohttp#588 via vbmithr) * Require `ppx_type_conv`>=v0.9.1` due to a bug with duplicate modules present in earlier versions. ## v1.0.1 (2018-01-03) * cohttp-mirage: expose the missing IO module (mirage/ocaml-cohttp#594, samoht) * cohttp-mirage: catch exceptions when closing channels in mirage client (mirage/ocaml-cohttp#589, ansiwen) ## v1.0.0 (2017-11-16) * opam: rename `mirage-http` to `cohttp`-mirage` (mirage/ocaml-cohttp#572) * cohttp-lwt{,-unix}: wrap the libraries in top-level modules (mirage/ocaml-cohttp#568) * opam: improve dependencies (mirage/ocaml-cohttp#574, mirage/ocaml-cohttp#566, mirage/ocaml-cohttp#575) * cohttp: add the convenience function `Header.is_empty` (mirage/ocaml-cohttp#576) * fix compatibility with OCaml 4.06 and `-safe-string` (mirage/ocaml-cohttp#580, mirage/ocaml-cohttp#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. ## 0.22.0 (2017-03-09) * Lwt: ensure conn_closed is closed once client goes away (mirage/ocaml-cohttp#528) * Use the Logs library for logging.

(mirage/ocaml-cohttp#420) 0.19.1 (2015-08-08): * Bring make_body_writer and write_header in Cohttp.S.Http_io. Needed by ocaml-git 0.19.0 (2015-08-05): Compatibility breaking interface changes: * Remove `read_form` from the `Request/Response/Header` interfaces as this should be done in `Body` handling instead (mirage/ocaml-cohttp#401). New features and bug fixes: * Remove `IO.write_line` as it was unused in any interfaces. * Do not use the `lwt` camlp4 extension. No observable external difference. * Do not return a code stacktrace in the default 500 handler. * Add `Cohttp.Header.compare` (mirage/ocaml-cohttp#411) * Fix typos in CLI documentation (mirage/ocaml-cohttp#413 via moonlightdrive) * Use the Lwt 2.5.0 buffer API. * `Cohttp_lwt.read_response` now has a non-optional `closefn` parameter (mirage/ocaml-cohttp#400). * Add a `Cohttp_lwt_s` module that contains all the Lwt module types in one convenient place (mirage/ocaml-cohttp#397). 0.18.3 (2015-07-12): * Allow `DELETE` requests to have request bodies (mirage/ocaml-cohttp#383). * Improve the Lwt client `callv` for HTTP/1.1 pipelined requests (mirage/ocaml-cohttp#379 via Török Edwin). 0.18.2 (2015-06-19): * Do not add content encoding for 204's (mirage/ocaml-cohttp#375) 0.18.1 (2015-06-05): * Remove trailing whitespace from headers (mirage/ocaml-cohttp#372) * Don't reverse order of list valued headers (mirage/ocaml-cohttp#372) 0.18.0 (2015-06-02): * Add Cohttp_async.Client.callv. Allows for making requests while reusing an HTTP connection (mirage/ocaml-cohttp#344) * Responses of status 1xx/204/304 have no bodies and cohttp should not attempt to read them (mirage/ocaml-cohttp#355) * Add top level printers. See cohttp.top findlib package (mirage/ocaml-cohttp#363) * Add `Header.to_string` (mirage/ocaml-cohttp#362) * Fix chunk truncation in chunked transfer encoding (mirage/ocaml-cohttp#360) Compatibility breaking interface changes: * Remove `Request`/`Response` modules outside of Cohttp pack (mirage/ocaml-cohttp#349) 0.17.2 (2015-05-24): * Remove dependency on the Lwt Camlp4 syntax extension (mirage/ocaml-cohttp#334). * Add `make github` target to push documentation to GitHub Pages (mirage/ocaml-cohttp#338 from Jyotsna Prakash). * Add Async integration tests and consolidate Lwt tests using the new framework (mirage/ocaml-cohttp#337). * Fix allocation of massive buffer when handling fixed size http bodies (mirage/ocaml-cohttp#345) 0.17.1 (2015-04-24): * [async] Limit buffer size to a maximum of 32K in the Async backend (mirage/ocaml-cohttp#330 from Stanislav Artemkin). * Add `Cohttp.Conf.version` with the library version number included. * Remove debug output from `cohttp-curl-async`. * Add the beginning of a `DESIGN.md` document to explain the library structure. 0.17.0 (2015-04-17): Compatibility breaking interface changes: * `CONNECT` and `TRACE` methods added to `Code`.Exhaustive matches will need updating. New features and bug fixes: * `Link` header parsing has been added as `Cohttp.Link`, `Header.get_links` and `Header.add_links` * `cohttp_server_*` now obeys `HEAD` requests and responds 405 to unknown methods * `Cohttp_async.Server.response` type is now exposed as a `response * body` pair * Failure to read a body in a pipelined response no longer terminates the stream * Fix `cohttp_curl_lwt -X HEAD` sending empty chunked body (mirage/ocaml-cohttp#313) * Fix a bug which left extra `\r\n` in buffer at end of chunked reads * Fix handling of request URI for query strings and `CONNECT` proxies (mirage/ocaml-cohttp#308, mirage/ocaml-cohttp#318) * Fix precedence of `Host` header when request-URI is absolute URI * Fix request URI path to be non-empty except for * requests (e.g. `OPTIONS *`) 0.16.1 (2015-04-09): New features and bug fixes: * Fix handling of request paths starting with multiple slashes (mirage/ocaml-cohttp#308) 0.16.0 (2015-03-23): Compatibility breaking interface changes: * Response.t and Request.t fields are no longer mutable * [lwt] Fix types in `post_form` to be a `string * string list` instead of a `Header.t` (mirage/ocaml-cohttp#257) * Simplify the `Net` signature which needs to be provided for Lwt servers to not be required. Only the Lwt client needs a `Net` functor argument to make outgoing connections. (mirage/ocaml-cohttp#274) * The `Request` and `Response` records are no longer mutable, so use functional updates instead via `Fieldslib.Field.fset Request.Fields.<field>`. (mirage/ocaml-cohttp#296) * `Request.has_body` does not permit a body to be set for methods that RFC7231 forbids from having one (`HEAD`, `GET` and `DELETE`). New features and bug fixes: * Fix linking problem caused by sub-libraries using cohttp modules outside the cohttp pack. * Added async client for S3. (mirage/ocaml-cohttp#304) * Fix String_io.read_line to trim '\r' from end of string (mirage/ocaml-cohttp#300) * Fix `cohttp-server-lwt` to correctly bind to a specific interface (mirage/ocaml-cohttp#298). * Add `Cohttp_async.request` to send raw, unmodified requests. * Supplying a `content-range` or `content-range` header in any client request will always override any other encoding preference (mirage/ocaml-cohttp#281). * Add a `cohttp-lwt-proxy` to act as an HTTP proxy. (mirage/ocaml-cohttp#248) * Extend `cohttp-server-async` file server to work with HTTPS (mirage/ocaml-cohttp#277). * Copy basic auth from `Uri.userinfo` into the Authorization header for HTTP requests. (mirage/ocaml-cohttp#255) * Install binaries via an OPAM `.install` file to ensure that they are reliably uninstalled. (mirage/ocaml-cohttp#252) * Use the `magic-mime` library to add a MIME type by probing filename during static serving in the Lwt/Async backends. (mirage/ocaml-cohttp#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 (mirage/ocaml-cohttp#246). * `Server.respond` no longer overrides user-supplied headers that specify the `content-length` or `transfer-encoding` headers (mirage/ocaml-cohttp#268). * `cohttp_server_lwt` and `cohttp_server_async` now include sizes in directory listing titles * Add `Header.add_multi` to initialise a header structure with multiple fields more efficiently (mirage/ocaml-cohttp#272). * Expose `IO.ic` and `IO.oc` types for `Cohttp_async` (mirage/ocaml-cohttp#271). * Skip empty body chunks in `Transfer_io.write` (mirage/ocaml-cohttp#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 (mirage/ocaml-cohttp#282). * `cohttp-curl-lwt` now takes http method as parameter (mirage/ocaml-cohttp#288) * Fix installation of server binaries in OPAM metadata. (mirage/ocaml-cohttp#295) 0.15.2 (2015-02-15): * When transfer encoding is unknown, read until EOF when body size is unknown. (mirage/ocaml-cohttp#241) * Add some missing documentation to `Cohttp.S.IO` signature. (mirage/ocaml-cohttp#233) * Add `Cohttp.Header.mem` to check if a header exists. * Add `Cohttp.Conf` module to expose the library version number. (mirage/ocaml-cohttp#259) * Add `Cohttp.Header.add_unless_exists` to update a key if it doesn't already exist. (mirage/ocaml-cohttp#244) * Add `Cohttp.Header.get_location` to retrieve redirection information. (mirage/ocaml-cohttp#254) * [async] Clean up the `Net.lookup` function to use `Or_error.t` instead of raising. (mirage/ocaml-cohttp#247) * [tests] Add more tests for `content-range` handling. (mirage/ocaml-cohttp#249) 0.15.1 (2015-01-10): * Lwt 2.4.7 renamed `blit_bytes_string` to `blit_to_bytes`, so depend on the newer API now. (mirage/ocaml-cohttp#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. (mirage/ocaml-cohttp#218 via Runhang Li) * Improve `oasis` constraints and regenerate `opam` file (mirage/ocaml-cohttp#229 via Christophe Troestler). 0.15.0 (2014-12-24): Compatibility breaking interface changes: * Change `Cohttp_lwt_body.map` to use a non-labelled type to fit the Lwt style better (mirage/ocaml-cohttp#200). * Depend on Base64 version 2, which uses `B64` as the toplevel module name (mirage/ocaml-cohttp#220). New features and bug fixes: * Remove use of deprecated `Lwt_unix.run` and replace it with `Lwt_main.run`. Should be no observable external change (mirage/ocaml-cohttp#217). * Improve ocamldoc of `Cohttp.S` signature (mirage/ocaml-cohttp#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 (mirage/ocaml-cohttp#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 ``` * Remove the `Cohttp.Base64` module in favour of the external `base64` library (which is now a new dependency). New features and bug fixes: * Lwt `respond_error` now defaults to an internal server error if no status code is specified (mirage/ocaml-cohttp#212). * Modernise the `opam` file using the OPAM 1.2 workflow (mirage/ocaml-cohttp#211). * Flush the response body to the network by default, rather than buffering by default. The `?flush` optional parameter can still be explicitly set to false if flushing is not desired (mirage/ocaml-cohttp#205). 0.13.0 (2014-12-05): 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 (mirage/ocaml-cohttp#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 (mirage/ocaml-cohttp#158) * `cohttp_server_lwt` and `cohttp_server_async` now serve indexes directly (mirage/ocaml-cohttp#162) * [lwt] Add `stop` thread to terminate a running server if it finishes (mirage/ocaml-cohttp#147). * Add `Cohttp.Connection.compare` to make ordering of connections possible. * Add `Body.map` and `Body.as_pipe` to work with HTTP bodies more easily. * Remove link-time dependency on camlp4 via META fixes (mirage/ocaml-cohttp#127). * Support HTTP methods and versions other than the standard ones. (mirage/ocaml-cohttp#142). * Improve `cohttp_server_lwt` and `cohttp_server_async` directory listings (mirage/ocaml-cohttp#158) * Fix `Cohttp_async.resolve_local_file` directory traversal vulnerability (mirage/ocaml-cohttp#158) * [async] In the Async server, do not close the Reader too early. * [async] Close file descriptors more eagerly in the HTTP client (mirage/ocaml-cohttp#167). * Reduce thread allocation by replacing `return <const>` with `return_none`, `return_unit` or `return_nil`. 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 (mirage/ocaml-cohttp#116). * Add an Lwt-based SimpleHTTPServer equivalent as `cohttp-server-lwt` (mirage/ocaml-cohttp#108). * `Cohttp.Connection.t` now exposes sexp accessor functions (mirage/ocaml-cohttp#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 (mirage/ocaml-cohttp#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 some module type equalities in `Cohttp_lwt_unix` so that `Cohttp_lwt_unix.Server.Request.IO.ic` can be equivalen to `Lwt_io.input_channel`. * Add sexp converters to most Cohttp types (mirage/ocaml-cohttp#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. 0.9.15 (2014-01-11): * Remove `Cohttp_mirage` libraries, which have now moved to `mirage/mirage-http-*` on GitHub. * Add an "HTTP only" `Cookie` attribute (mirage/ocaml-cohttp#69). * Fix parsing of cookies with `=` in the values (mirage/ocaml-cohttp#71). * Add `Max-age` support for cookies (mirage/ocaml-cohttp#70). * Make the `Response` record fields mutable to match the `Request` (mirage/ocaml-cohttp#67). * Fix compilation with Async 109.58.00 (mirage/ocaml-cohttp#77). * Make Header handling case-insensitive (by forcing lowercase) (mirage/ocaml-cohttp#75). * Remove the `>>` operator as it was unused and had incorrect precedence (mirage/ocaml-cohttp#79). 0.9.14 (2013-12-15): * Install a `cohttp-server` binary that serves local directory contents via a web server (mirage/ocaml-cohttp#54). * Add a `flush` function to the `IO` module type and implement in Lwt/Async/Mirage. * Add option `flush` support in the Async and Lwt responders (mirage/ocaml-cohttp#52). * Autogenerate HTTP codes from citricsquid's JSON representation of the HTTP RFCs. * Always set `TCP_NODELAY` for Lwt/Unix server sockets for low-latency responses (mirage/ocaml-cohttp#58). * Added a Server-Side Events test-case from the HTML5 Doctor. See `lib_test/README.md`. * Async.Server response now takes an optional `body` rather than a mandatory `body option` (mirage/ocaml-cohttp#62). * Regenerate build system using OASIS 0.4.0. 0.9.13 (2013-12-10): * The `cohttp.lwt-core` is now installed as an OS-independent Lwt library. * Add support for Mirage 1.0, via `cohttp.mirage-unix` and `cohttp.mirage-xen`. * Add a new `Cohttp.Connection` module to manage server's connections identifiers. * Share the same configuration type for the different server implementations. * Add `Accept_types` module to the `Cohttp` pack. 0.9.12 (2013-11-28): * Improve documentation for `Cohttp.Header`. * Expose Fieldslib setters and getters for most of the `Cohttp` types (mirage/ocaml-cohttp#38). * `Cohttp.Set_cookie.t` is no longer an abstract type to make it easier to update (mirage/ocaml-cohttp#38). * [Lwt] ignore SIGPIPE unconditionally if using the Lwt/Unix module (mirage/ocaml-cohttp#37). * Rename `Cookie` creation parameters for consistency (interface breaking, see mirage/ocaml-cohttp#44). * Fix transfer-length detection (regression from 0.9.11 in mirage/ocaml-cohttp#42). * Add Merin editor file (mirage/ocaml-cohttp#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. * TCP server: When creating the socket for the server, do not force PF_INET6 but take the sockaddr value. * Add HTTP OPTIONS method. * Use getaddrinfo instead of gethostbyname for DNS resolution. * Async: improve HTTP/1.0 support (mirage/ocaml-cohttp#35). * Build with debug symbols, binary annotations by default. * Add Travis CI test scripts. 0.9.10 (2013-06-21): * 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): * Disable the mirage executable test as it was building too aggressively and breaking builds. 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`. * Do not depend on Cstruct in core library, as only Mirage needs it. * Remove `Cohttp_async.body` type alias and just use `string Pipe.Reader.t` for more explicit types. 0.9.7 (2013-05-10): * Attach a GC finaliser to the Lwt client to ensure that even an HTTP body isn't consumed, the socket will eventually be closed (mirage/ocaml-cohttp#11). * 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). * Add user agent string and User-Agent header helper function * The git history of this release is full of adventures in parameterised monads and refactoring, but this isn't in the actual release. Yet. 0.9.6 (2013-03-18): * Depend on Async (>= 109.12.00), which has an incompatible API with earlier versions. * Rearrange core library files for `obuild` support. 0.9.5 (2012-12-29): * Fix cookie parsing to retrieve the correct header. * Update to `mirage-net` 0.5.0 API (based on cstruct 0.6.0). 0.9.4 (2012-12-19): * Add Lwt `respond_redirect` and `respond_need_auth` helpers. * Add enough Basic authorization support to serve a password-protected website. * Fix Lwt file serving to not throw exception on trying to serve a directory. * Port Async interface to 108.07.00 or higher (incompatible with earlier versions). 0.9.3 (2012-10-27): * Add basic cookie support back to the portable library. * `Cohttp_lwt.Client.post_form` now uses non-chunked encoding for the POST instead of chunked. * Various improvements and tests for the pipelined Lwt Client.callv * If an Lwt callback does not consume a body, ensure it has been drained by the API to prevent future pipelines from stalls. * Fix handling of Lwt server non-empty POST bodies. * Map the `put` functions to HTTP PUT instead of POST. 0.9.2 (2012-09-20): * Add Request.get_param to extract a singleton key from queries. * Fix chunked encoding handling when short reads occur. * Install HTML documentation for all enabled drivers. * Use ocaml-uri-1.3.2 interface for query parsing. * Lwt: Add Server.respond_file and resolve_file for the Unix library to make it easier to serve static files. * Lwt: Server.respond_not_found takes an optional Uri.t now. 0.9.1 (2012-09-11): * Functorise for Async, Lwt_unix and Mirage. * Use URI and Re libraries to not need Str any more. * More robust parsing for various HTTP headers. 0.9.0 (2012-08-01): * Initial public release.
