# Changelog

All notable changes to this project will be documented in this file, in reverse chronological order by release.

## 2.8.2 - 2018-08-13

### Added

- Nothing.

### Changed

- [#153](https://github.com/zendframework/zend-diactoros/pull/153) changes the reason phrase associated with the status code 425
  from "Unordered Collection" to "Too Early", corresponding to a new definition
  of the code as specified by the IANA.

### Deprecated

- Nothing.

### Removed

- Nothing.

### Fixed

- [#151](https://github.com/zendframework/zend-http/pull/151) fixes how Referer and other location-based headers report problems with
  invalid URLs provided in the header value, raising a `Zend\Http\Exception\InvalidArgumentException`
  in such cases. This change ensures the behavior is consistent with behavior
  prior to the 2.8.0 release.

## 2.8.1 - 2018-08-01

### Added

- Nothing.

### Changed

- This release modifies how `Zend\Http\PhpEnvironment\Request` 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 zend-http.

  If you are developing a zend-mvc application, you can mimic the
  functionality by adding a bootstrap listener like the following:

  ```php
  public function onBootstrap(MvcEvent $mvcEvent)
  {
      $request = $mvcEvent->getRequest();
      $requestUri = null;

      $httpXRewriteUrl = $request->getHeader('X-Rewrite-Url');
      if ($httpXRewriteUrl) {
          $requestUri = $httpXRewriteUrl->getFieldValue();
      }

      $httpXOriginalUrl = $request->getHeader('X-Original-Url');
      if ($httpXOriginalUrl) {
          $requestUri = $httpXOriginalUrl->getFieldValue();
      }

      if ($requestUri) {
          $request->setUri($requestUri)
      }
  }
  ```

  If you use a listener 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.

## 2.8.0 - 2018-04-26

### Added

- [#135](https://github.com/zendframework/zend-http/pull/135) adds a package suggestion of paragonie/certainty, which provides automated
  management of cacert.pem files.

- [#143](https://github.com/zendframework/zend-http/pull/143) adds support for PHP 7.2.

### Changed

- Nothing.

### Deprecated

- Nothing.

### Removed

- Nothing.

### Fixed

- [#140](https://github.com/zendframework/zend-http/pull/140) fixes retrieval of headers when multiple headers of the same name
  are added to the `Headers` instance; it now ensures that the last header added of the same
  type is retrieved when it is not a multi-value type. Previous values are overwritten.

- [#112](https://github.com/zendframework/zend-http/pull/112) provides performance improvements when parsing large chunked messages.

- introduces changes to `Response::fromString()` to pull the next line of the response
  and parse it for the status when a 100 status code is initially encountered, per https://tools.ietf.org/html/rfc7231\#section-6.2.1

- [#122](https://github.com/zendframework/zend-http/pull/122) fixes an issue with the stream response whereby if the `outputstream`
  option is set, the output file was opened twice; it is now opened exactly once.

- [#147](https://github.com/zendframework/zend-http/pull/147) fixes an issue with header retrieval when the header line is malformed.
  Previously, an exception would be raised if a specific `HeaderInterface` implementation determined
  the header line was invalid. Now, `Header::has()` will return false for such headers, allowing
  `Request::getHeader()` to return `false` or the provided default value. Additionally, in cases
  where the header name is malformed (e.g., `Useragent` instead of `User-Agent`, users can still
  retrieve by the submitted header name; they will receive a `GenericHeader` instance in such
  cases, however.

- [#133](https://github.com/zendframework/zend-http/pull/133) Adds back missing
  sprintf placeholder in CacheControl exception message

## 2.7.0 - 2017-10-13

  codes 226, 308, 444, 499, 510, 599 with their corresponding constants and
  reason phrases.

### Changed

- [#120](https://github.com/zendframework/zend-http/pull/120) Changes handling
  of Cookie Max-Age parameter to conform to specification
  [rfc6265#section-5.2.2](https://tools.ietf.org/html/rfc6265#section-5.2.2).
  Specifically, non-numeric values are ignored and negative numbers are changed
  to 0.

### Removed

- Nothing.

### Fixed

- [#107](https://github.com/zendframework/zend-http/pull/107) fixes the
  `Expires` header to allow values of `0` or `'0'`; these now resolve
  to the start of the unix epoch (1970-01-01).
- [#102](https://github.com/zendframework/zend-http/pull/102) fixes the Curl
  adapter timeout detection.
- [#93](https://github.com/zendframework/zend-http/pull/93) fixes the Content
  Security Policy CSP HTTP header when it is `none` (empty value).
- [#92](https://github.com/zendframework/zend-http/pull/92) fixes the flatten
  cookies value for array value (also multidimensional).
- [#34](https://github.com/zendframework/zend-http/pull/34) fixes the
  standard separator (&) for application/x-www-form-urlencoded.

## 2.5.5 - 2016-08-08

### Added

- [#44](https://github.com/zendframework/zend-http/pull/44),
  [#45](https://github.com/zendframework/zend-http/pull/45),
  [#46](https://github.com/zendframework/zend-http/pull/46),
  [#47](https://github.com/zendframework/zend-http/pull/47),
  [#48](https://github.com/zendframework/zend-http/pull/48), and
  [#49](https://github.com/zendframework/zend-http/pull/49) prepare the
  documentation for publication at https://zendframework.github.io/zend-http/

### Deprecated

- Nothing.

### Removed

- Nothing.

### Fixed

- [#87](https://github.com/zendframework/zend-http/pull/87) fixes the
  `ContentLength` constructor to test for a non null value (vs a falsy value)
  before validating the value; this ensures 0 values may be specified for the
  length.
- [#85](https://github.com/zendframework/zend-http/pull/85) fixes infinite recursion
  on AbstractAccept. If you create a new Accept and try to call getFieldValue(),
  an infinite recursion and a fatal error happens.
- [#58](https://github.com/zendframework/zend-http/pull/58) avoid triggering a notice
  with special crafted accept headers. In the case the value of an accept header
  does not contain an equal sign, an "Undefined offset" notice is triggered.

## 2.5.4 - 2016-02-04

### Added

- Nothing.

### Deprecated

- Nothing.

### Removed

- Nothing.

### Fixed

- [#42](https://github.com/zendframework/zend-http/pull/42) updates dependencies
  to ensure it can work with PHP 5.5+ and 7.0+, as well as zend-stdlib
  2.5+/3.0+.

## 2.5.3 - 2015-09-14

### Added

- Nothing.

### Deprecated

- Nothing.

### Removed

- Nothing.

### Fixed

- [#23](https://github.com/zendframework/zend-http/pull/23) fixes a BC break
  introduced with fixes for [ZF2015-04](http://framework.zend.com/security/advisory/ZF2015-04),
  pertaining specifically to the `SetCookie` header. The fix backs out a
  check for message splitting syntax, as that particular class already encodes
  the value in a manner that prevents the attack. It also adds tests to ensure
  the security vulnerability remains patched.

## 2.5.2 - 2015-08-05

### Added

- Nothing.

### Deprecated

- Nothing.

### Removed

- Nothing.

### Fixed

- [#7](https://github.com/zendframework/zend-http/pull/7) fixes a call in the
  proxy adapter to `Response::extractCode()`, which does not exist, to
  `Response::fromString()->getStatusCode()`, which does.
- [#8](https://github.com/zendframework/zend-http/pull/8) ensures that the Curl
  client adapter enables the `CURLINFO_HEADER_OUT`, which is required to ensure
  we can fetch the raw request after it is sent.
- [#14](https://github.com/zendframework/zend-http/pull/14) fixes
  `Zend\Http\PhpEnvironment\Request` to ensure that empty `SCRIPT_FILENAME` and
  `SCRIPT_NAME` values which result in an empty `$baseUrl` will not raise an
  `E_WARNING` when used to do a `strpos()` check during base URI detection.
