Tutorial by Topics: management



This topic outlines how and when the Swift runtime shall allocate memory for application data structures, and when that memory shall be reclaimed. By default, the memory backing class instances is managed through reference counting. The structures are always passed through copying. To opt out of the built-in memory management scheme, one could use [Unmanaged][1] structure. [1]: https://developer.apple.com/reference/swift/unmanaged

Management commands are powerful and flexible scripts that can perform actions on your Django project or the underlying database. In addition to various default commands, it's possible to write your own!

Compared to regular Python scripts, using the management command framework means that some tedious setup work is automatically done for you behind the scenes.

For managing dynamically allocated memory, the standard C library provides the functions malloc(), calloc(), realloc() and free(). In C99 and later, there is also aligned_alloc(). Some systems also provide alloca().

When using the Assetic Bundle, according to the Symfony documentation, please be aware of the following:

Starting from Symfony 2.8, Assetic is no longer included by default in the Symfony Standard Edition. Before using any of its features, install the AsseticBundle executing this console command in your project:

$ composer require symfony/assetic-bundle

There are other steps you have to take. For more information go to: http://symfony.com/doc/current/assetic/asset_management.html
