+# Changelog
+
+## 1.4.0 (2017-08-18)
+
+*   Feature / Fix: The `fun()` function does not pass filter parameter `null`
+    to underlying `stream_filter_append()` by default
+    (#15 by @Nyholm)
+
+    Certain filters (such as `convert.quoted-printable-encode`) do not accept
+    a filter parameter at all. If no explicit filter parameter is given, we no
+    longer pass a default `null` value.
+
+    ```php
+    $encode = Filter\fun('convert.quoted-printable-encode');
+    assert('t=C3=A4st' === $encode('täst'));
+    ```
+
+*   Add examples and improve documentation
+    (#13 and #20 by @clue and #18 by @Nyholm)
+
+*   Improve test suite by adding PHPUnit to require-dev,
+    fix HHVM build for now again and ignore future HHVM build errors,
+    lock Travis distro so new future defaults will not break the build
+    and test on PHP 7.1
+    (#12, #14 and #19 by @clue and #16 by @Nyholm)
+
+## 1.3.0 (2015-11-08)
+
+*   Feature: Support accessing built-in filters as callbacks
+    (#5 by @clue)
+
+    ```php
+    $fun = Filter\fun('zlib.deflate');
+

+
+## Why?
+
+PHP's stream filtering system is great!
+
+It offers very powerful stream filtering options and comes with a useful set of built-in filters.
+These filters can be used to easily and efficiently perform various transformations on-the-fly, such as:
+
+* read from a gzip'ed input file,
+* transcode from ISO-8859-1 (Latin1) to UTF-8,
+* write to a bzip output file
+* and much more.
+
+But let's face it:
+Its API is [*difficult to work with*](http://php.net/manual/en/php-user-filter.filter.php)
+and its documentation is [*subpar*](http://stackoverflow.com/questions/27103269/what-is-a-bucket-brigade).
+This combined means its powerful features are often neglected.
+
+This project aims to make these features more accessible to a broader audience.
+* **Lightweight, SOLID design** -
+  Provides a thin abstraction that is [*just good enough*](http://en.wikipedia.org/wiki/Principle_of_good_enough)
+  and does not get in your way.
+  Custom filters require trivial effort.
+* **Good test coverage** -
+  Comes with an automated tests suite and is regularly tested in the *real world*
+
+## Usage
+
+This lightweight library consists only of a few simple functions.
+All functions reside under the `Clue\StreamFilter` namespace.
+
+The below examples assume you use an import statement similar to this:
+
+```php
+use Clue\StreamFilter as Filter;
+
+Filter\append(…);
+```
+
+Alternatively, you can also refer to them with their fully-qualified name:
+
+```php
+\Clue\StreamFilter\append(…);
+```
+
+### append()
+
+The `append($stream, $callback, $read_write = STREAM_FILTER_ALL)` function can be used to
+append a filter callback to the given stream.
+
+Each stream can have a list of filters attached.
+This function appends a filter to the end of this list.
+
+This function returns a filter resource which can be passed to [`remove()`](#remove).
+If the given filter can not be added, it throws an `Exception`.
+
+The `$stream` can be any valid stream resource, such as:
+
+```php
+$stream = fopen('demo.txt', 'w+');
+```
+
+The `$callback` should be a valid callable function which accepts an individual chunk of data
+and should return the updated chunk:
+
+```php
+$filter = Filter\append($stream, function ($chunk) {
+    // will be called each time you read or write a $chunk to/from the stream
+    return $chunk;
+});
+```
+
+As such, you can also use native PHP functions or any other `callable`:
+
+```php
+Filter\append($stream, 'strtoupper');
+
+// will write "HELLO" to the underlying stream
+fwrite($stream, 'hello');
+```
+
+If the `$callback` accepts invocation without parameters, then this signature
+will be invoked once ending (flushing) the filter:
+
+```php
+Filter\append($stream, function ($chunk = null) {
+    if ($chunk === null) {
+        // will be called once ending the filter
+        return 'end';
+    }
+    // will be called each time you read or write a $chunk to/from the stream
+    return $chunk;
+});
+
+fclose($stream);
+```
+
+> Note: Legacy PHP versions (PHP < 5.4) do not support passing additional data
+from the end signal handler if the stream is being closed.
+
+If your callback throws an `Exception`, then the filter process will be aborted.
+In order to play nice with PHP's stream handling, the `Exception` will be
+transformed to a PHP warning instead:
+
+```php
+Filter\append($stream, function ($chunk) {
+    throw new \RuntimeException('Unexpected chunk');
+});
+
+// raises an E_USER_WARNING with "Error invoking filter: Unexpected chunk"
+fwrite($stream, 'hello');
+```
+
+The optional `$read_write` parameter can be used to only invoke the `$callback` when either writing to the stream or only when reading from the stream:
+
+```php
+Filter\append($stream, function ($chunk) {
+    // will be called each time you write to the stream
+    return $chunk;
+}, STREAM_FILTER_WRITE);
+
+Filter\append($stream, function ($chunk) {
+    // will be called each time you read from the stream
+    return $chunk;
+}, STREAM_FILTER_READ);
+```
+
+> Note that once a filter has been added to stream, the stream can no longer be passed to
+> [`stream_select()`](http://php.net/manual/en/function.stream-select.php)
+> (and family).
+>
+> > Warning: stream_select(): cannot cast a filtered stream on this system in {file} on line {line}
+>
+> This is due to limitations of PHP's stream filter support, as it can no longer reliably
+> tell when the underlying stream resource is actually ready.
+> As an alternative, consider calling `stream_select()` on the unfiltered stream and
+> then pass the unfiltered data through the [`fun()`](#fun) function.
+
+### prepend()
+
+The `prepend($stream, $callback, $read_write = STREAM_FILTER_ALL)` function can be used to
+prepend a filter callback to the given stream.
+
+Each stream can have a list of filters attached.
+This function prepends a filter to the start of this list.
+
+This function returns a filter resource which can be passed to [`remove()`](#remove).
+If the given filter can not be added, it throws an `Exception`.
+
+```php
+$filter = Filter\prepend($stream, function ($chunk) {
+    // will be called each time you read or write a $chunk to/from the stream
+    return $chunk;
+});
+```
+
+Except for the position in the list of filters, this function behaves exactly
+like the [`append()`](#append) function.
+For more details about its behavior, see also the [`append()`](#append) function.
+
+### fun()
+
+The `fun($filter, $parameters = null)` function can be used to
+create a filter function which uses the given built-in `$filter`.
+
+PHP comes with a useful set of [built-in filters](http://php.net/manual/en/filters.php).
+Using `fun()` makes accessing these as easy as passing an input string to filter
+and getting the filtered output string.
+
+```php
+$fun = Filter\fun('string.rot13');
+
+assert('grfg' === $fun('test'));
+assert('test' === $fun($fun('test'));
+```
+
+Please note that not all filter functions may be available depending on installed
+PHP extensions and the PHP version in use.
+In particular, [HHVM](http://hhvm.com/) may not offer the same filter functions
+or parameters as Zend PHP.
+Accessing an unknown filter function will result in a `RuntimeException`:
+
+```php
+Filter\fun('unknown'); // throws RuntimeException
+```
+
+Some filters may accept or require additional filter parameters – most
+filters do not require filter parameters.
+If given, the optional `$parameters` argument will be passed to the
+underlying filter handler as-is.
+In particular, note how *not passing* this parameter at all differs from
+explicitly passing a `null` value (which many filters do not accept).
+Please refer to the individual filter definition for more details.
+For example, the `string.strip_tags` filter can be invoked like this:
+
+```php
+$fun = Filter\fun('string.strip_tags', '<a><b>');
+
+$ret = $fun('<b>h<br>i</b>');
+assert('<b>hi</b>' === $ret);
+```
+
+Under the hood, this function allocates a temporary memory stream, so it's
+recommended to clean up the filter function after use.
+Also, some filter functions (in particular the
+[zlib compression filters](http://php.net/manual/en/filters.compression.php))
+may use internal buffers and may emit a final data chunk on close.
+The filter function can be closed by invoking without any arguments:
+
+```php
+$fun = Filter\fun('zlib.deflate');
+
+$ret = $fun('hello') . $fun('world') . $fun();
+assert('helloworld' === gzinflate($ret));
+```
+
+The filter function must not be used anymore after it has been closed.
+Doing so will result in a `RuntimeException`:
+
+```php
+$fun = Filter\fun('string.rot13');
+$fun();
+
+$fun('test'); // throws RuntimeException
+```
+
+> Note: If you're using the zlib compression filters, then you should be wary
+about engine inconsistencies between different PHP versions and HHVM.
+These inconsistencies exist in the underlying PHP engines and there's little we
+can do about this in this library.
+[Our test suite](tests/) contains several test cases that exhibit these issues.
+If you feel some test case is missing or outdated, we're happy to accept PRs! :)
+
+### remove()
+
+The `remove($filter)` function can be used to
+remove a filter previously added via [`append()`](#append) or [`prepend()`](#prepend).
+
+```php
+$filter = Filter\append($stream, function () {
+    // …
+});
+Filter\remove($filter);
+```
+
+## Install
+
+The recommended way to install this library is [through Composer](https://getcomposer.org).
+[New to Composer?](https://getcomposer.org/doc/00-intro.md)
+
+This will install the latest supported version:
+
+```bash
+$ composer require clue/stream-filter:^1.4
+```
+
+See also the [CHANGELOG](CHANGELOG.md) for details about version upgrades.
+
+This project aims to run on any platform and thus does not require any PHP
+extensions and supports running on legacy PHP 5.3 through current PHP 7+ and
+HHVM.
+It's *highly recommended to use PHP 7+* for this project.
+Older PHP versions may suffer from a number of inconsistencies documented above.
+
+## Tests
+
+To run the test suite, you first need to clone this repo and then install all
+dependencies [through Composer](http://getcomposer.org):
+
+```bash
+$ composer install
+```
+
+To run the test suite, go to the project root and run:
+
+```bash
+$ php vendor/bin/phpunit
+```

+# PHP GitHub API
+
+[![Build Status](https://travis-ci.org/KnpLabs/php-github-api.svg?branch=master)](https://travis-ci.org/KnpLabs/php-github-api)
+[![StyleCI](https://styleci.io/repos/3948501/shield?style=flat)](https://styleci.io/repos/3948501)
+[![Latest Stable Version](https://poser.pugx.org/knplabs/github-api/v/stable)](https://packagist.org/packages/knplabs/github-api)
+[![Total Downloads](https://poser.pugx.org/knplabs/github-api/downloads)](https://packagist.org/packages/knplabs/github-api)

+[![Daily Downloads](https://poser.pugx.org/knplabs/github-api/d/daily)](https://packagist.org/packages/knplabs/github-api)
+
+A simple Object Oriented wrapper for GitHub API, written with PHP5.
+
+Uses [GitHub API v3](http://developer.github.com/v3/) & supports [GitHub API v4](http://developer.github.com/v4). The object API (v3) is very similar to the RESTful API.
+
+## Features
+
+* Light and fast thanks to lazy loading of API classes
+* Extensively tested and documented
+
+## Requirements
+
+* PHP >= 5.6
+* A [HTTP client](https://packagist.org/providers/php-http/client-implementation)
+* A [PSR-7 implementation](https://packagist.org/providers/psr/http-message-implementation)
+* (optional) PHPUnit to run tests.
+
+## Install
+
+Via Composer:
+
+```bash
+$ composer require knplabs/github-api php-http/guzzle6-adapter
+```
+
+Why `php-http/guzzle6-adapter`? We are decoupled from any HTTP messaging client with help by [HTTPlug](http://httplug.io/). Read about clients in our [docs](doc/customize.md).
+
+
+## Using Laravel?
+
+[Laravel GitHub](https://github.com/GrahamCampbell/Laravel-GitHub) by [Graham Campbell](https://github.com/GrahamCampbell) might interest you.
+
+## Basic usage of `php-github-api` client
+
+```php
+<?php
+
+// This file is generated by Composer
+require_once __DIR__ . '/vendor/autoload.php';
+
+$client = new \Github\Client();
+$repositories = $client->api('user')->repositories('ornicar');
+```
+
+From `$client` object, you can access to all GitHub.
+
+## Cache usage
+
+This example uses the PSR6 cache pool [redis-adapter](https://github.com/php-cache/redis-adapter). See http://www.php-cache.com/ for alternatives.
+
+```php
+<?php
+
+// This file is generated by Composer
+require_once __DIR__ . '/vendor/autoload.php';
+
+use Cache\Adapter\Redis\RedisCachePool;
+
+$client = new \Redis();
+$client->connect('127.0.0.1', 6379);
+// Create a PSR6 cache pool
+$pool = new RedisCachePool($client);
+
+$client = new \Github\Client();
+$client->addCache($pool);
+
+// Do some request
+
+// Stop using cache
+$client->removeCache();
+```
+
+Using cache, the client will get cached responses if resources haven't changed since last time,
+**without** reaching the `X-Rate-Limit` [imposed by github](http://developer.github.com/v3/#rate-limiting).

+# Change Log
+
+## 1.5.0 - 2017-11-29
+
+### Added
+
+* Support for Symfony 4
+
+### Changed
+
+* Removed check if etag is a string. Etag can never be a string, it is always an array. 
+
+## 1.4.0 - 2017-04-05
+
+### Added 
+
+- `CacheKeyGenerator` interface that allow you to configure how the PSR-6 cache key is created. There are two implementations
+of this interface: `SimpleGenerator` (default) and `HeaderCacheKeyGenerator`.
+
+### Fixed
+
+- Issue where deprecation warning always was triggered. Not it is just triggered if `respect_cache_headers` is used. 
+
+## 1.3.0 - 2017-03-28
+
+### Added
+
+- New `methods` option which allows to configure the request methods which can be cached.
+- New `respect_response_cache_directives` option to define specific cache directives to respect when handling responses.
+- Introduced `CachePlugin::clientCache` and `CachePlugin::serverCache` factory methods to easily setup the plugin with 
+  the correct config settigns for each usecase.
+
+### Changed
+
+- The `no-cache` directive is now respected by the plugin and will not cache the response. If you need the previous behaviour, configure `respect_response_cache_directives`.
+- We always rewind the stream after loading response from cache. 
+
+### Deprecated
+
+- The `respect_cache_headers` option is deprecated and will be removed in 2.0. This option is replaced by the new `respect_response_cache_directives` option.
+  If you had set `respect_cache_headers` to `false`, set the directives to `[]` to ignore all directives.
+
+
+## 1.2.0 - 2016-08-16
+
+### Changed
+
+- The default value for `default_ttl` is changed from `null` to `0`.
+
+### Fixed
+
+- Issue when you use `respect_cache_headers=>false` in combination with `default_ttl=>null`.
+- We allow `cache_lifetime` to be set to `null`.
+
+
+## 1.1.0 - 2016-08-04
+
+### Added
+
+- Support for cache validation with ETag and Last-Modified headers. (Enabled automatically when the server sends the relevant headers.)
+- `hash_algo` config option used for cache key generation (defaults to **sha1**).
+
+### Changed
+
+- Default hash algo used for cache generation (from **md5** to **sha1**).
+
+### Fixed
+
+- Cast max age header to integer in order to get valid expiration value.
+
+
+## 1.0.0 - 2016-05-05
+
+- Initial release

+# Change Log
+
+## 1.8.1 - 2018-10-09
+
+### Fixed
+
+- Reverted change to RetryPlugin so it again waits when retrying to avoid "can only throw objects" error.
+
+## 1.8.0 - 2018-09-21
+
+### Added
+
+ - Add an option on ErrorPlugin to only throw exception on response with 5XX status code.
+
+### Changed
+
+- AddPathPlugin no longer add prefix multiple times if a request is restarted - it now only adds the prefix if that request chain has not yet passed through the AddPathPlugin
+- RetryPlugin no longer wait for retried requests and use a deferred promise instead
+
+### Fixed
+
+- Decoder plugin will now remove header when there is no more encoding, instead of setting to an empty array
+
+
+## 1.7.0 - 2017-11-30
+
+### Added 
+
+- Symfony 4 support
+
+### Changed
+
+- Strict comparison in DecoderPlugin
+
+## 1.6.0 - 2017-10-16
+
+### Added
+
+- Add HttpClientPool client to leverage load balancing and fallback mechanism [see the documentation](http://docs.php-http.org/en/latest/components/client-common.html) for more details.
+- `PluginClientFactory` to create `PluginClient` instances.
+- Added new option 'delay' for `RetryPlugin`.
+- Added new option 'decider' for `RetryPlugin`.
+- Supports more cookie date formats in the Cookie Plugin
+
+### Changed
+
+- The `RetryPlugin` does now wait between retries. To disable/change this feature you must write something like: 
+ 
+```php
+$plugin = new RetryPlugin(['delay' => function(RequestInterface $request, Exception $e, $retries) { 
+  return 0; 
+}); 
+```
+
+### Deprecated
+
+- The `debug_plugins` option for `PluginClient` is deprecated and will be removed in 2.0. Use the decorator design pattern instead like in [ProfilePlugin](https://github.com/php-http/HttplugBundle/blob/de33f9c14252f22093a5ec7d84f17535ab31a384/Collector/ProfilePlugin.php).

+### Deprecated
+
+- `DecoderPlugin` does not longer claim to support `compress` content encoding
+
+### Fixed
+
+- `CookiePlugin` allows main domain cookies to be sent/stored for subdomains
+- `DecoderPlugin` uses the right `FilteredStream` to handle `deflate` content encoding
+
+

+
+### Fixed
+
+- Cast return value of `StreamInterface::getSize` to string in `ContentLengthPlugin`

+- Add BaseUriPlugin that combines AddHostPlugin and AddPathPlugin
+
+
+## 1.2.1 - 2016-07-26
+
+### Changed
+
+- AddHostPlugin also sets the port if specified
+
+

+# Change Log
+
+## 1.4.0 - 2018-02-06
+
+### Added
+
+- Discovery support for nyholm/psr7
+
+## 1.3.0 - 2017-08-03
+
+### Added
+
+- Discovery support for CakePHP adapter
+- Discovery support for Zend adapter
+- Discovery support for Artax adapter
+
+## 1.2.1 - 2017-03-02
+
+### Fixed
+
+- Fixed minor issue with `MockClientStrategy`, also added more tests. 
+
+## 1.2.0 - 2017-02-12
+
+### Added
+
+- MockClientStrategy class.
+
+## 1.1.1 - 2016-11-27
+
+### Changed
+
+- Made exception messages clearer. `StrategyUnavailableException` is no longer the previous exception to `DiscoveryFailedException`.
+- `CommonClassesStrategy` is using `self` instead of `static`. Using `static` makes no sense when `CommonClassesStrategy` is final.
+
+## 1.1.0 - 2016-10-20
+
+### Added
+
+- Discovery support for Slim Framework factories
+
+## 1.0.0 - 2016-07-18
+
+### Added
+
+- Added back `Http\Discovery\NotFoundException` to preserve BC with 0.8 version. You may upgrade from 0.8.x and 0.9.x to 1.0.0 without any BC breaks.
+- Added interface `Http\Discovery\Exception` which is implemented by all our exceptions
+
+### Changed
+
+- Puli strategy renamed to Puli Beta strategy to prevent incompatibility with a future Puli stable
+
+### Deprecated
+
+- For BC reasons, the old `Http\Discovery\NotFoundException` (extending the new exception) will be thrown until version 2.0
+
+
+## 0.9.1 - 2016-06-28
+
+### Changed
+
+- Dropping PHP 5.4 support because we use the ::class constant.
+
+
+## 0.9.0 - 2016-06-25
+
+### Added
+
+- Discovery strategies to find classes
+
+### Changed
+
