什么是新的Symfony 3目录结构?

我刚刚使用常规编写器命令创建了一个新的Symfony 2.5项目:

php composer.phar create-project symfony/framework-standard-edition path/ 2.5.0

航站楼问我:

  

您想使用Symfony 3目录结构吗?

这个 Symfony 3目录结构是什么?我之前从未见过它......自2.5以来它是新的吗?

使用它有什么好处?

有没有办法复制这个目录结构?

我想使用新的Symfony 3目录结构,但我没有看到这个问题?

创建新项目时,问题Would you like to use Symfony 3 directory structure?已被删除,因为它引起了混乱。您可以使用以下命令强制使用目录结构:

如果您更喜欢新结构,可以将环境变量SENSIOLABS_ENABLE_NEW_DIRECTORY_STRUCTURE添加到.bashrc.bash_profile,如下所示:

让所有未来项目都要求新结构

# .bash_profile
# ALL new composer installs will ask `Would you like to use the new Symfony3 strucure?`
export SENSIOLABS_ENABLE_NEW_DIRECTORY_STRUCTURE=true

仅限该项目询问我们是否要使用新结构。

如果您只想要一个特定项目(一次性),您可以使用:

SENSIOLABS_ENABLE_NEW_DIRECTORY_STRUCTURE=true composer create-project symfony/framework-standard-edition path/ "2.5.*"

如果设置了环境变量SENSIOLABS_ENABLE_NEW_DIRECTORY_STRUCTURE并将其设置为true,则composer会询问您是否要使用新的目录结构。

继续阅读以下Symfony2Symfony3目录结构之间的所有更改。


新的Symfony 3目录结构是什么?

(以及它如何影响我和我的工作流程)

我通过创建2个项目来研究这个问题,一个项目具有symfony-2.5.0目录结构,一个项目具有symfony-3(仅限目录结构更改)。

制作每个项目之一:

# say `N` to `Would you like to use Symfony 3 directory structure?`
$ composer create-project symfony/framework-standard-edition symfony-2.5.0/ 2.5.0

# say `Y` to `Would you like to use Symfony 3 directory structure?`
$ composer create-project symfony/framework-standard-edition symfony-3/ 2.5.0

所以现在我们有两个不同的目录要比较。


找到diff erence

您可以使用以下两个目录之间diff

$ diff -rq symfony-2.5.0/ symfony-3/
/** (Returned from the diff)
Files symfony-2.5.0/.gitignore and symfony-3/.gitignore differ
Files symfony-2.5.0/.travis.yml and symfony-3/.travis.yml differ
Only in symfony-2.5.0/app: bootstrap.php.cache
Only in symfony-2.5.0/app: cache
Only in symfony-2.5.0/app: console
Only in symfony-2.5.0/app: logs
Only in symfony-2.5.0/app: phpunit.xml.dist
Only in symfony-3/bin: console
Only in symfony-3/bin: symfony_requirements
Files symfony-2.5.0/composer.json and symfony-3/composer.json differ
Only in symfony-3/: phpunit.xml.dist
Only in symfony-3/: var
Files symfony-2.5.0/vendor/autoload.php and symfony-3/vendor/autoload.php differ
Files symfony-2.5.0/vendor/composer/autoload_real.php and symfony-3/vendor/composer/autoload_real.php differ
Files symfony-2.5.0/web/app.php and symfony-3/web/app.php differ
Files symfony-2.5.0/web/app_dev.php and symfony-3/web/app_dev.php differ
*/

这显示了2个版本中不同的文件。


diff

的细分

这是差异中所有内容的细分。

# These files still exist in both versions (with different content)
.gitignore
.travis.yml
composer.json
vendor/autoload.php
vendor/composer/autoload_real.php
web/app.php
web/app_dev.php

# The following files have been removed from 2.5.0
# {RemovedFile2.5}      |  {ReplacedWith3.0}
app/cache               |  var/cache
app/logs                |  var/log
app/bootstrap.php.cache |  var/bootstrap.php.cache
app/console             |  bin/console
app/phpunit.xml.dist    |  phpunit.xml.dist

# The following files are new in 3.0
bin/symfony_requirements # run via CLI

Symfony 3目录结构的好处

新目录结构具有许多优点,所有这些优点都很小,可能只需要对您的工作流程进行最少的更改。

PHPUnit的

可以从项目根运行

phpunit,而无需显式指定配置文件的路径。

# Symfony2
phpunit -c app/phpunit.xml

# Symfony3 (no need to specify the configuration file location)
phpunit

二进制可执行文件

所有二进制可执行文件现在都位于一个位置 - bin目录(类似于类似unix的操作系统)

# you can update your `PATH` to include the `bin` directory
PATH="./bin:$PATH"

# From your project root you can now run executables like so:
console
symfony_requirements
doctrine

# else with no `PATH` update
bin/console
bin/symfony_requirements
bin/doctrine

新的/var目录

新的/var目录包含系统在其操作过程中将数据写入的文件(类似于类似于unix的操作系统)

这也使得添加权限变得更容易,整个/var目录应该可以由您的网络服务器写入。您可以关注Symfony2 guide for setting permissions(用app/cache替换app/logs& var),您想在本地写的任何其他文件也可以在此处找到。

# default symfony3 `var` directory
var/bootstrap.php.cache
var/cache
var/logs

Symfony要求检查

正在运行symfony_requirements将输出强制性&可选的环境配置 e.g:

********************************
* 'Symfony requirements check' *
********************************

* Configuration file used by PHP: /usr/local/php5/lib/php.ini

/** ATTENTION **
*  The PHP CLI can use a different php.ini file
*  than the one used with your web server.
*  To be on the safe side, please also launch the requirements check
*  from your web server using the web/config.php script.
*/

结论

Sensio Labs看起来是一个很好的整理,所有上述变化都非常有意义,从2.5升级到3.x时它们应该很容易实现,这些可能是您的最小值问题!

Updated Symfony release Process

答案 1 :(得分:38)

以下是旧目录结构和新目录结构之间的更改列表:

  • 引入了新的var文件夹
  • app/console已移至bin/console
  • app/check.php被移动/重命名为bin/symfony_requirements
  • app/phpunit.xml.dist已移至根文件夹
  • app/SymfonyRequirements.php已移至var/SymfonyRequirements.php
  • app/cacheapp/logs文件夹已分别移至var/cachevar/logs

(目前并非所有旧文件都被删除,因此您可能需要在将所有文件提交到版本控制之前手动执行此操作。请参阅this issue

那么有什么好处?

这些变化有几个好处。首先,Symfony应该可写的所有文件和文件夹现在都在var文件夹中。这应该使配置权限变得更加容易:只需确保对var文件夹的写访问权限即可完成。 这是this blog post中的建议 - 我自己还没有尝试过这个。

其次,所有可执行文件(包括console)现在都在bin文件夹中。这允许Bash用户将其添加到他们的.profile文件中:

# set PATH so it includes current bin folder
PATH="./bin:$PATH"

现在你甚至不必再输入bin/console,只需console即可(请注意我必须重新启动才能使其正常工作)。

还有其他一些改进。 app/check.php现在是可执行文件,因此您可以使用bin/symfony_requirements而不是php app/check.php来调用它。 (使用我之前描述的.profile技巧,只需symfony_requirements就足够了)

最后但并非最不重要的是,您不再需要在运行PHPUnit时指定配置文件的位置。因此,您只需执行phpunit -c app而不是phpunit

我是否可以将现有项目升级到这个新结构?

默认情况下,您只会获得“是否要使用新目录结构”#39;创建新项目时的问题(使用composer create-project symfony/framework-standard-edition path/ "2.5.*")。

但是,可以升级现有的Symfony应用程序,但这是一个有点hacky的解决方案。我现在已经设法使用了许多应用程序,您可以阅读in this gist步骤。但是,由于它不是为此而设计的,我无法保证它将始终有效。

更新

事实证明,在通过Composer创建新的Symfony应用程序时,Symfony不再询问您是否要使用新的目录结构。但是,仍然可以使用环境变量使用新目录结构创建Symfony项目。有关详细信息,请参阅How can I create a new Symfony project with the new directory structure?
