/**
|
|
* Creates sample folder and file structure, useful to test performance,
|
|
* UI behaviour on deeply nested structures etc.
|
|
*
|
|
* Downloads around 20MB of data from a public web location on first run,
|
|
* in order to create reasonable fixture data (and keep it out of the module repo).
|
|
* The related AWS S3 bucket is managed by SilverStripe Ltd.
|
|
*
|
|
* Protip: In case you want to test thumbnail generation, you can
|
|
* recursively delete any generated ones through the following bash command in `assets/`:
|
|
* `find . -name '*Resampled*' -print0 | xargs -0 rm`
|
|
*
|
|
* Parameters:
|
|
* - reset=1: Optionally truncate ALL files and folders in the database, plus delete
|
|
* the entire `assets/` directory.
