Zend Diactoros Laravel Package

Added

• Nothing.

Changed

• #379 removes extension of SplFileInfo by the UploadedFile class. The signatures of getSize() are potentially incompatible, and UploadedFile is intended to work with arbitrary PHP and PSR-7 streams, whereas SplFileInfo can only model files on the filesystem. While this is technically a BC break, we are treating it as a bugfix, as the class was broken for many use cases.

• #372 fixes issues that occur in the Zend\Diactoros\Uri class when invalid UTF-8 characters are present the user-info, path, or query string, ensuring they are URL-encoded before being consumed. Previously, such characters could result in a fatal error, which was particularly problematic when marshaling the request URI for an application request cycle.

Fixed

• #337 ensures that the ServerRequestFactory::createServerRequest() method creates a php://temp stream instead of a php::input stream, in compliance with the PSR-17 specification.

Added

• #326 adds PSR-17 HTTP Message Factory implementations, including:

  • Zend\Diactoros\RequestFactory
  • Zend\Diactoros\ResponseFactory
  • Zend\Diactoros\ServerRequestFactory
  • Zend\Diactoros\StreamFactory
  • Zend\Diactoros\UploadedFileFactory
  • Zend\Diactoros\UriFactory

  These factories may be used to produce the associated instances; we encourage users to rely on the PSR-17 factory interfaces to allow exchanging PSR-7 implementations within their applications.

• #328 adds a package-level exception interface, Zend\Diactoros\Exception\ExceptionInterface, and several implementations for specific exceptions raised within the package. These include:

  • Zend\Diactoros\Exception\DeserializationException (extends UnexpectedValueException)
  • Zend\Diactoros\Exception\InvalidArgumentException (extends InvalidArgumentException)
  • Zend\Diactoros\Exception\InvalidStreamPointerPositionException (extends RuntimeException)
  • Zend\Diactoros\Exception\SerializationException (extends UnexpectedValueException)
  • Zend\Diactoros\Exception\UnreadableStreamException (extends RuntimeException)
  • Zend\Diactoros\Exception\UnrecognizedProtocolVersionException (extends UnexpectedValueException)
  • Zend\Diactoros\Exception\UnrewindableStreamException (extends RuntimeException)
  • Zend\Diactoros\Exception\UnseekableStreamException (extends RuntimeException)
  • Zend\Diactoros\Exception\UntellableStreamException (extends RuntimeException)
  • Zend\Diactoros\Exception\UnwritableStreamException (extends RuntimeException)
  • Zend\Diactoros\Exception\UploadedFileAlreadyMovedException (extends RuntimeException)
  • Zend\Diactoros\Exception\UploadedFileErrorException (extends RuntimeException)

Changed

• #329 adds return type hints and scalar parameter type hints wherever possible. The changes were done to help improve code quality, in part by reducing manual type checking. If you are extending any classes, you may need to update your signatures; check the signatures of the class(es) you are extending for changes.

• #162 modifies Serializer\Request such that it now no longer raises an UnexpectedValueException via its toString() method when an unexpected HTTP method is encountered; this can be done safely, as the value can never be invalid due to other changes in the same patch.

• #162 modifies RequestTrait such that it now invalidates non-string method arguments to either the constructor or withMethod(), raising an InvalidArgumentException for any that do not validate.

Deprecated

• Nothing.

Removed

• #308 removes the following methods from the ServerRequestFactory class:

  • normalizeServer() (use Zend\Diactoros\normalizeServer() instead)
  • marshalHeaders() (use Zend\Diactoros\marshalHeadersFromSapi() instead)
  • marshalUriFromServer() (use Zend\Diactoros\marshalUriFromSapi() instead)
  • marshalRequestUri() (use Uri::getPath() from the Uri instance returned by marshalUriFromSapi() instead)
  • marshalHostAndPortFromHeaders() (use Uri::getHost() and Uri::getPort() from the Uri instances returned by marshalUriFromSapi() instead)
  • stripQueryString() (use explode("?", $path, 2)[0] instead)
  • normalizeFiles() (use Zend\Diactoros\normalizeUploadedFiles() instead)

• #295 removes Zend\Diactoros\Server. You can use the RequestHandlerRunner class from zendframework/zend-httphandlerrunner to provide these capabilities instead.

• #295 removes Zend\Diactoros\Response\EmitterInterface and the various emitter implementations. These can now be found in the package zendframework/zend-httphandlerrunner, which also provides a PSR-7-implementation agnostic way of using them.

Fixed

• Nothing.

Added

• Nothing.

Changed

• #325 changes the behavior of ServerRequest::withParsedBody(). Per PSR-7, it now no longer allows values other than null, arrays, or objects.

• #325 changes the behavior of each of Request, ServerRequest, and Response in relation to the validation of header values. Previously, we allowed empty arrays to be provided via withHeader(); however, this was contrary to the PSR-7 specification. Empty arrays are no longer allowed.

Deprecated

• Nothing.

Removed

• Nothing.

Fixed

• #325 ensures that Uri::withUserInfo() no longer ignores values of 0 (numeric zero).

• #325 fixes how header values are merged when calling withAddedHeader(), ensuring that array keys are ignored.

Added

• Nothing.

Changed

• Nothing.

Deprecated

• Nothing.

Removed

• Nothing.

Fixed

• #324 fixes a reference to an undefined variable in the ServerRequestFactory, which made it impossible to fetch a specific header by name.

Added

• Nothing.

Changed

• This release modifies how ServerRequestFactory marshals the request URI. In prior releases, we would attempt to inspect the X-Rewrite-Url and X-Original-Url headers, using their values, if present. These headers are issued by the ISAPI_Rewrite module for IIS (developed by HeliconTech). However, we have no way of guaranteeing that the module is what issued the headers, making it an unreliable source for discovering the URI. As such, we have removed this feature in this release of Diactoros.

  If you are developing a middleware application, you can mimic the functionality via middleware as follows:

  use Psr\Http\Message\ResponseInterface;
  use Psr\Http\Message\ServerRequestInterface;
  use Psr\Http\Server\RequestHandlerInterface;
  use Zend\Diactoros\Uri;
  
  public function process(ServerRequestInterface $request, RequestHandlerInterface $handler) : ResponseInterface
  {
      $requestUri = null;
  
      $httpXRewriteUrl = $request->getHeaderLine('X-Rewrite-Url');
      if ($httpXRewriteUrl !== null) {
          $requestUri = $httpXRewriteUrl;
      }
  
      $httpXOriginalUrl = $request->getHeaderLine('X-Original-Url');
      if ($httpXOriginalUrl !== null) {
          $requestUri = $httpXOriginalUrl;
      }
  
      if ($requestUri !== null) {
          $request = $request->withUri(new Uri($requestUri));
      }
  
      return $handler->handle($request);
  }
  

  If you use middleware such as the above, make sure you also instruct your web server to strip any incoming headers of the same name so that you can guarantee they are issued by the ISAPI_Rewrite module.

Removed

Fixed

• #321 updates the logic in Uri::withPort() to ensure that it checks that the value provided is either an integer or a string integer, as only those values may be cast to integer without data loss.

• #320 adds checking within Response to ensure that the provided reason phrase is a string; an InvalidArgumentException is now raised if it is not. This change ensures the class adheres strictly to the PSR-7 specification.

• #319 provides a fix to Zend\Diactoros\Response that ensures that the status code returned is always an integer (and never a string containing an integer), thus ensuring it strictly adheres to the PSR-7 specification.

Added

• Nothing.

Changed

• Nothing.

Deprecated

• Nothing.

Removed

• Nothing.

Fixed

• #318 fixes the logic for discovering whether an HTTPS scheme is in play to be case insensitive when comparing header and SAPI values, ensuring no false negative lookups occur.

• #314 modifies error handling around opening a file resource within Zend\Diactoros\Stream::setStream() to no longer use the second argument to set_error_handler(), and instead check the error type in the handler itself; this fixes an issue when the handler is nested inside another error handler, which currently has buggy behavior within the PHP engine.

Added

• Nothing.

Changed

• #313 changes the reason phrase associated with the status code 425 to "Too Early", corresponding to a new definition of the code as specified by the IANA.

Deprecated

• Nothing.

Removed

• Nothing.

Fixed

• #312 fixes how the normalizeUploadedFiles() utility function handles nested trees of uploaded files, ensuring it detects them properly.

Added

• #307 adds the following functions under the Zend\Diactoros namespace, each of which may be used to derive artifacts from SAPI supergloabls for the purposes of generating a ServerRequest instance:
  • normalizeServer(array $server, callable $apacheRequestHeaderCallback = null) : array (main purpose is to aggregate the Authorization header in the SAPI params when under Apache)
  • marshalProtocolVersionFromSapi(array $server) : string
  • marshalMethodFromSapi(array $server) : string
  • marshalUriFromSapi(array $server, array $headers) : Uri
  • marshalHeadersFromSapi(array $server) : array
  • parseCookieHeader(string $header) : array
  • createUploadedFile(array $spec) : UploadedFile (creates the instance from a normal $_FILES entry)
  • normalizeUploadedFiles(array $files) : UploadedFileInterface[] (traverses a potentially nested array of uploaded file instances and/or $_FILES entries, including those aggregated under mod_php, php-fpm, and php-cgi in order to create a flat array of UploadedFileInterface instances to use in a request)

Changed

• Nothing.

Deprecated

• #307 deprecates ServerRequestFactory::normalizeServer(); the method is no longer used internally, and users should instead use Zend\Diactoros\normalizeServer(), to which it proxies.

• #307 deprecates ServerRequestFactory::marshalHeaders(); the method is no longer used internally, and users should instead use Zend\Diactoros\marshalHeadersFromSapi(), to which it proxies.

• #307 deprecates ServerRequestFactory::marshalUriFromServer(); the method is no longer used internally. Users should use marshalUriFromSapi() instead.

• #307 deprecates ServerRequestFactory::marshalRequestUri(). the method is no longer used internally, and currently proxies to marshalUriFromSapi(), pulling the discovered path from the Uri instance returned by that function. Users should use marshalUriFromSapi() instead.

• #307 deprecates ServerRequestFactory::marshalHostAndPortFromHeaders(); the method is no longer used internally, and currently proxies to marshalUriFromSapi(), pulling the discovered host and port from the Uri instance returned by that function. Users should use marshalUriFromSapi() instead.

• #307 deprecates ServerRequestFactory::getHeader(); the method is no longer used internally. Users should copy and paste the functionality into their own applications if needed, or rely on headers from a fully-populated Uri instance instead.

• #307 deprecates ServerRequestFactory::stripQueryString(); the method is no longer used internally, and users can mimic the functionality via the expression $path = explode('?', $path, 2)[0];.

• #307 deprecates ServerRequestFactory::normalizeFiles(); the functionality is no longer used internally, and users can use normalizeUploadedFiles() as a replacement.

• #303 deprecates Zend\Diactoros\Response\EmitterInterface and its various implementations. These are now provided via the zendframework/zend-httphandlerrunner package as 1:1 substitutions.

• #303 deprecates the Zend\Diactoros\Server class. Users are directed to the RequestHandlerRunner class from the zendframework/zend-httphandlerrunner package as an alternative.

Fixed

• #301 adds stricter comparisons within the uri class to ensure non-empty values are not treated as empty.

Added

• Nothing.

Changed

• #293 updates Uri::getHost() to cast the value via strtolower() before returning it. While this represents a change, it is fixing a bug in our implementation: the PSR-7 specification for the method, which follows IETF RFC 3986 section 3.2.2, requires that the host name be normalized to lowercase.

Deprecated

• Nothing.

Removed

• Nothing.

Fixed

• #290 fixes Stream::getSize() such that it checks that the result of fstat was succesful before attempting to return its size member; in the case of an error, it now returns null.

Added

• #285 adds a new custom response type, Zend\Diactoros\Response\XmlResponse, for generating responses representing XML. Usage is the same as with the HtmlResponse or TextResponse; the response generated will have a Content-Type: application/xml header by default.

• #280 adds the response status code/phrase pairing "103 Early Hints" to the Response::$phrases property. This is a new status proposed via RFC 8297.

• #279 adds explicit support for PHP 7.2; previously, we'd allowed build failures, though none occured; we now require PHP 7.2 builds to pass.

Changed

• Nothing.

Deprecated

Removed

Added

Changed

• #273 updates each of the SAPI emitter implementations to emit the status line after emitting other headers; this is done to ensure that the status line is not overridden by PHP.

Deprecated

• Nothing.

Removed

• Nothing.

Fixed

• #273 modifies how the SapiEmitterTrait calls header() to ensure that a response code is always passed as the third argument; this is done to prevent PHP from silently overriding it.

Added

• Nothing.

Changed

• #270 changes the behavior of Zend\Diactoros\Server: it no longer creates an output buffer.

• #270 changes the behavior of the two SAPI emitters in two backwards-incompatible ways:

  • They no longer auto-inject a Content-Length header. If you need this functionality, zendframework/zend-expressive-helpers 4.1+ provides it via Zend\Expressive\Helper\ContentLengthMiddleware.

  • They no longer flush the output buffer. Instead, if headers have been sent, or the output buffer exists and has a non-zero length, the emitters raise an exception, as mixed PSR-7/output buffer content creates a blocking issue. If you are emitting content via echo, print, var_dump, etc., or not catching PHP errors or exceptions, you will need to either fix your application to always work with a PSR-7 response, or provide your own emitters that allow mixed output mechanisms.

Deprecated

• Nothing.

Removed

• Nothing.

Fixed

• Nothing.

Added

• #205 adds support for PHP 7.2.

• #250 adds a new API to JsonResponse to avoid the need for decoding the response body in order to make changes to the underlying content. New methods include:

  • getPayload(): retrieve the unencoded payload.
  • withPayload($data): create a new instance with the given data.
  • getEncodingOptions(): retrieve the flags to use when encoding the payload to JSON.
  • withEncodingOptions(int $encodingOptions): create a new instance that uses the provided flags when encoding the payload to JSON.

Changed

• #249 changes the behavior of the various Uri::with*() methods slightly: if the value represents no change, these methods will return the same instance instead of a new one.

• #248 changes the behavior of Uri::getUserInfo() slightly: it now (correctly) returns the percent-encoded values for the user and/or password, per RFC 3986 Section 3.2.1. withUserInfo() will percent-encode values, using a mechanism that prevents double-encoding.

• #243 changes the exception messages thrown by UploadedFile::getStream() and moveTo() when an upload error exists to include details about the upload error.

• #233 adds a new argument to SapiStreamEmitter::emit, $maxBufferLevel between the $response and $maxBufferLength arguments. This was done because the Server::listen() method passes only the response and $maxBufferLevel to emitters; previously, this often meant that streams were being chunked 2 bytes at a time versus the expected default of 8kb.

  If you were calling the SapiStreamEmitter::emit() method manually previously, you will need to update your code.

Deprecated

• Nothing.

Removed

• #205 and #243 remove support for PHP versions prior to 5.6 as well as HHVM.

Fixed

• #248 fixes how the Uri class provides user-info within the URI authority; the value is now correctly percent-encoded , per RFC 3986 Section 3.2.1.

Added

• Nothing.

Deprecated

• Nothing.

Removed

• #260 removes support for HHVM, as tests have failed against it for some time.

Fixed

• #247 fixes the Stream and RelativeStream __toString() method implementations to check if the stream isSeekable() before attempting to rewind() it, ensuring that the method does not raise exceptions (PHP does not allow exceptions in that method). In particular, this fixes an issue when using AWS S3 streams.

• #252 provides a fix to the SapiEmitterTrait to ensure that any Set-Cookie headers in the response instance do not override those set by PHP when a session is created and/or regenerated.

• #257 provides a fix for the PhpInputStream::read() method to ensure string content that evaluates as empty (including 0) is still cached.

• #258 updates the Uri::filterPath() method to allow parens within a URI path, per RFC 3986 section 3.3 (parens are within the character set "sub-delims").

Added

• #219 adds two new classes, Zend\Diactoros\Request\ArraySerializer and Zend\Diactoros\Response\ArraySerializer. Each exposes the static methods toArray() and fromArray(), allowing de/serialization of messages from and to arrays.

• #236 adds two new constants to the Response class: MIN_STATUS_CODE_VALUE and MAX_STATUS_CODE_VALUE.

Changes

• #240 changes the behavior of ServerRequestFactory::fromGlobals() when no $cookies argument is present. Previously, it would use $_COOKIES; now, if a Cookie header is present, it will parse and use that to populate the instance instead.

  This change allows utilizing cookies that contain period characters (.) in their names (PHP's built-in cookie handling renames these to replace . with _, which can lead to synchronization issues with clients).

• #235 changes the behavior of Uri::__toString() to better follow proscribed behavior in PSR-7. In particular, prior to this release, if a scheme was missing but an authority was present, the class was incorrectly returning a value that did not include a // prefix. As of this release, it now does this correctly.

Deprecated

Added

Changes

• #241 changes the constraint by which the package provides psr/http-message-implementation to simply 1.0 instead of ~1.0.0, to follow how other implementations provide PSR-7.

Deprecated

• Nothing.

Removed

• Nothing.

Fixed

• #161 adds additional validations to header names and values to ensure no malformed values are provided.

• #234 fixes a number of reason phrases in the Response instance, and adds automation from the canonical IANA sources to ensure any new phrases added are correct.

Added

• Nothing.

Deprecated

• Nothing.

Removed

• Nothing.

Fixed

• #226 fixed an issue with the SapiStreamEmitter causing the response body to be cast to (string) and also be read as a readable stream, potentially producing double output.
