shelf 1.1.4

A model for web server middleware that encourages composition and easy reuse

1.1.4

• Documentation improvements.

1.1.3

• Automatically remove content-length header from a Response.notModified. Restores some of the safety around malformed requests that was removed in 1.1.2 where we started allowing content-length for some responses without bodies.
• Documentation cleanup.

1.1.2

• Allow an explicit non-zero content-length header if the body is empty. (Needed to correctly support HEAD requests).

1.1.1

• Avoid wrapping response bodies that already contained List<int> or Stream<List<int>> in a CastList/CastStream to improve performance.

1.1.0

• Change Request.hijack return type from void to Never. This may cause analysis hints in packages using this method, but is not actually breaking for apps.

1.0.0

• Stable null safety release.

1.0.0-nullsafety.0

• Update to support Dart null-safety.
• Updated the change function on Request and Response to clear existing values in context if the provided context value has null values.

0.7.9

• Allow a handlerPath to lead up to a double // in a URI.

0.7.8

• Handle malformed URLs (400 instead of 500).

0.7.7

• Fix internal error in Request when .change() matches the full path.

0.7.6

• Supports multiple header values in Request and Response:
  • headersAll field contains all the header values
  • headers field contains the same values as previously (appending values with ,)
  • headers parameter in the constructor and in the .change() method accepts both String and List<String> values.

0.7.5

• Return the correct HTTP status code for badly formatted requests.

0.7.4+1

• Allow stream_channel version 2.x

0.7.4

• Allow passing shared parameter to underlying HttpServer.bind calls via shelf_io.serve.
• Correctly pass encoding in Response constructors forbidden, notFound, and internalServerError.
• Update README.md to point to latest docs.

0.7.3+3

• Set max SDK version to <3.0.0, and adjust other dependencies.

0.7.3+2

• Fix constant evaluation analyzer error in shelf_unmodifiable_map.dart.

• Update usage of HTTP constants from the Dart SDK. Now require 2.0.0-dev.61.

0.7.3+1

• Updated SDK version to 2.0.0-dev.55.0.

0.7.3

• Fix some Dart 2 runtime errors.

0.7.2

• Update createMiddleware arguments to use FutureOr.

  • Note: this change is not breaking for the runtime behavior, but it might cause new errors during static analysis due the the type changes.

• Updated minimum Dart SDK to 1.24.0, which added FutureOr.

• Improved formatting of the logRequests default logger.

0.7.1

• The shelf_io server now adds a shelf.io.connection_info field to Request.context, which provides access to the underlying HttpConnectionInfo object.

0.7.0

• Give a return type to the Handler typedef. This may cause static warnings where there previously were none, but all handlers should have already been returning a Response or Future<Response>.

• Remove HijackCallback and OnHijackCallback typedefs.

• Breaking: Change type of onHijack in the Request constructor to take an argument of StreamChannel.

0.6.8

• Add a securityContext parameter to self_io.serve().

0.6.7+2

• Go back to auto-generating a Content-Length header when the length is known ahead-of-time and the user hasn't explicitly specified a Transfer-Encoding: chunked.

• Clarify adapter requirements around transfer codings.

• Make shelf_io consistent with the clarified adapter requirements. In particular, it removes the Transfer-Encoding header from chunked requests, and it doesn't apply additional chunking to responses that already declare Transfer-Encoding: chunked.

0.6.7+1

• Never auto-generate a Content-Length header.

0.6.7

• Add Request.isEmpty and Response.isEmpty getters which indicate whether a message has an empty body.

• Don't automatically generate Content-Length headers on messages where they may not be allowed.

• User-specified Content-Length headers now always take precedence over automatically-generated headers.

0.6.6

• Allow List<int>s to be passed as request or response bodies.

• Requests and responses now automatically set Content-Length headers when the body length is known ahead of time.

• Work around sdk#27660 by manually setting HttpResponse.chunkedTransferEncoding to false for requests known to have no content.

0.6.5+3

• Improve the documentation of logRequests().

0.6.5+2

• Support http_parser 3.0.0.

0.6.5+1

• Fix all strong-mode warnings and errors.

0.6.5

• Request.hijack() now takes a callback that accepts a single StreamChannel argument rather than separate Stream and StreamSink arguments. The old callback signature is still supported, but should be considered deprecated.

• The HijackCallback and OnHijackCallback typedefs are deprecated.

0.6.4+3

• Support http_parser 2.0.0.

0.6.4+2

• Fix a bug where the Content-Type header didn't interact properly with the encoding parameter for new Request() and new Response() if it wasn't lowercase.

0.6.4+1

• When the shelf_io adapter detects an error, print the request context as well as the error itself.

0.6.4

• Add a Server interface representing an adapter that knows its own URL.

• Add a ServerHandler class that exposes a Server backed by a Handler.

• Add an IOServer class that implements Server in terms of dart:io's HttpServer.

0.6.3+1

• Cleaned up handling of certain Map instances and related dependencies.

0.6.3

• Messages returned by Request.change() and Response.change() are marked read whenever the original message is read, and vice-versa. This means that it's possible to read a message on which change() has been called and to call change() on a message more than once, as long as read() is called on only one of those messages.

0.6.2+1

• Support http_parser 1.0.0.

0.6.2

• Added a body named argument to change method on Request and Response.

0.6.1+3

• Updated minimum SDK to 1.9.0.

• Allow an empty url parameter to be passed in to new Request(). This fits the stated semantics of the class, and should not have been forbidden.

0.6.1+2

• logRequests outputs a better message a request has a query string.

0.6.1+1

• Don't throw a bogus exception for null responses.

0.6.1

• shelf_io now takes a "shelf.io.buffer_output" Response.context parameter that controls HttpResponse.bufferOutput.

• Fixed spelling errors in README and code comments.

0.6.0

Breaking change: The semantics of Request.scriptName and Request.url have been overhauled, and the former has been renamed to Request.handlerPath. handlerPath is now the root-relative URL path to the current handler, while url's path is the relative path from the current handler to the requested. The new semantics are easier to describe and to understand.

Practically speaking, the main difference is that the / at the beginning of url's path has been moved to the end of handlerPath. This makes url's path easier to parse using the path package.

Request.change's handling of handlerPath and url has also changed. Instead of taking both parameters separately and requiring that the user manually maintain all the associated guarantees, it now takes a single path parameter. This parameter is the relative path from the current handlerPath to the next one, and sets both handlerPath and url on the new Request accordingly.

0.5.7

• Updated Request to support the body model from Response.

0.5.6

• Fixed createMiddleware to only catch errors if errorHandler is provided.

• Updated handleRequest in shelf_io to more gracefully handle errors when parsing HttpRequest.

0.5.5+1

• Updated Request.change to include the original onHijack callback if one exists.

0.5.5

• Added default body text for Response.forbidden and Response.notFound if null is provided.

• Clarified documentation on a number of Response constructors.

• Updated README links to point to latest docs.

0.5.4+3

0.5.4+2

• Updated headers map to use a more efficient case-insensitive backing store.

0.5.4+1

• Widen the version constraint for stack_trace.

0.5.4

• The shelf_io adapter now sends the Date HTTP header by default.

• Fixed logic for setting Server header in shelf_io.

0.5.3

• Add new named parameters to Request.change: scriptName and url.

0.5.2

• Add a Cascade helper that runs handlers in sequence until one returns a response that's neither a 404 nor a 405.

• Add a Request.change method that copies a request with new header values.

• Add a Request.hijack method that allows handlers to gain access to the underlying HTTP socket.

0.5.1+1
