composer/semver
===============

Semver library that offers utilities, version constraint parsing and validation.

Originally written as part of [composer/composer](https://github.com/composer/composer),
now extracted and made available as a stand-alone library.

[![Build Status](https://travis-ci.org/composer/semver.svg?branch=master)](https://travis-ci.org/composer/semver)


Installation
------------

Install the latest version with:

```bash
$ composer require composer/semver
```


Requirements
------------

* PHP 5.3.2 is required but using the latest version of PHP is highly recommended.


Version Comparison
------------------

For details on how versions are compared, refer to the [Versions](https://getcomposer.org/doc/articles/versions.md)
article in the documentation section of the [getcomposer.org](https://getcomposer.org) website.


Basic usage
-----------

### Comparator

The `Composer\Semver\Comparator` class provides the following methods for comparing versions:

* greaterThan($v1, $v2)
* greaterThanOrEqualTo($v1, $v2)
* lessThan($v1, $v2)
* lessThanOrEqualTo($v1, $v2)
* equalTo($v1, $v2)
* notEqualTo($v1, $v2)

Each function takes two version strings as arguments and returns a boolean. For example:

```php
use Composer\Semver\Comparator;

Comparator::greaterThan(&#039;1.25.0&#039;, &#039;1.24.0&#039;); // 1.25.0 &gt; 1.24.0
```

### Semver

The `Composer\Semver\Semver` class provides the following methods:

* satisfies($version, $constraints)
* satisfiedBy(array $versions, $constraint)
* sort($versions)
* rsort($versions)

# Change Log

All notable changes to this project will be documented in this file.
This project adheres to [Semantic Versioning](http://semver.org/).

### [1.7.2] 2020-12-03

  * Fixed: Allow installing on php 8

### [1.7.1] 2020-09-27

  * Fixed: accidental validation of broken constraints combining ^/~ and wildcards, and -dev suffix allowing weird cases
  * Fixed: normalization of beta0 and such which was dropping the 0

### [1.7.0] 2020-09-09

  * Added: support for `x || @dev`, not very useful but seen in the wild and failed to validate with 1.5.2/1.6.0
  * Added: support for `foobar-dev` being equal to `dev-foobar`, dev-foobar is the official way to write it but we need to support the other for BC and convenience

### [1.6.0] 2020-09-08

  * Added: support for constraints like `^2.x-dev` and `~2.x-dev`, not very useful but seen in the wild and failed to validate with 1.5.2
  * Fixed: invalid aliases will no longer throw, unless explicitly validated by Composer in the root package

### [1.5.2] 2020-09-08

  * Fixed: handling of some invalid -dev versions which were seen as valid
  * Fixed: some doctypes

### [1.5.1] 2020-01-13

  * Fixed: Parsing of aliased version was not validating the alias to be a valid version

### [1.5.0] 2019-03-19

  * Added: some support for date versions (e.g. 201903) in `~` operator
  * Fixed: support for stabilities in `~` operator was inconsistent

### [1.4.2] 2016-08-30

  * Fixed: collapsing of complex constraints lead to buggy constraints

### [1.4.1] 2016-06-02

  * Changed: branch-like requirements no longer strip build metadata - [composer/semver#38](https://github.com/composer/semver/pull/38).

### [1.4.0] 2016-03-30

  * Added: getters on MultiConstraint - [composer/semver#35](https://github.com/composer/semver/pull/35).

### [1.3.0] 2016-02-25

  * Fixed: stability parsing - [composer/composer#1234](https://github.com/composer/composer/issues/4889).
  * Changed: collapse contiguous constraints when possible.

### [1.2.0] 2015-11-10

  * Changed: allow multiple numerical identifiers in &#039;pre-release&#039; version part.
  * Changed: add more &#039;v&#039; prefix support.

### [1.1.0] 2015-11-03

  * Changed: dropped redundant `test` namespace.
  * Changed: minor adjustment in datetime parsing normalization.
  * Changed: `ConstraintInterface` relaxed, setPrettyString is not required anymore.
  * Changed: `AbstractConstraint` marked deprecated, will be removed in 2.0.
  * Changed: `Constraint` is now extensible.

### [1.0.0] 2015-09-21

  * Break: `VersionConstraint` renamed to `Constraint`.
  * Break: `SpecificConstraint` renamed to `AbstractConstraint`.
  * Break: `LinkConstraintInterface` renamed to `ConstraintInterface`.
  * Break: `VersionParser::parseNameVersionPairs` was removed.
  * Changed: `VersionParser::parseConstraints` allows (but ignores) build metadata now.
  * Changed: `VersionParser::parseConstraints` allows (but ignores) prefixing numeric versions with a &#039;v&#039; now.
  * Changed: Fixed namespace(s) of test files.
  * Changed: `Comparator::compare` no longer throws `InvalidArgumentException`.
  * Changed: `Constraint` now throws `InvalidArgumentException`.

### [0.1.0] 2015-07-23

  * Added: `Composer\Semver\Comparator`, various methods to compare versions.
  * Added: various documents such as README.md, LICENSE, etc.
  * Added: configuration files for Git, Travis, php-cs-fixer, phpunit.
  * Break: the following namespaces were renamed:
    - Namespace: `Composer\Package\Version` -&gt; `Composer\Semver`
    - Namespace: `Composer\Package\LinkConstraint` -&gt; `Composer\Semver\Constraint`
    - Namespace: `Composer\Test\Package\Version` -&gt; `Composer\Test\Semver`
    - Namespace: `Composer\Test\Package\LinkConstraint` -&gt; `Composer\Test\Semver\Constraint`
  * Changed: code style using php-cs-fixer.

 * The scanner runs as root, but reading a tenant&#039;s WordPress database as root is
 * unsafe: a local MySQL superuser (e.g. root@localhost under unix_socket auth)
 * authenticates passwordlessly for an OS-root peer, so a crafted wp-config.php
 * could make the root process read any tenant&#039;s database. This decorator forks a
 * child, drops it to the site owner (supplementary groups + gid + uid, mirroring
 * the agent&#039;s safe_fileops drop), and runs the wrapped reader there — so the
 * connection authenticates as the tenant and is confined to that account&#039;s own
 * grants. The child returns the result over a socket pair and is then killed
 * without running PHP shutdown, so it never flushes/closes the parent&#039;s open
 * report database (WAL) or other inherited descriptors.
 *
 * Requires ext-pcntl and ext-posix. If either is missing the read is refused
 * (returns null -&gt; &#039;unknown&#039;) rather than falling back to a root connection.
