Fix bug where it was possible to submit blank text in various text fields. Caused by `String#blank?` not considering certain Unicode characters as blank. `blank?` is defined as `match?(/\A[[:space:]]*\z/)`, where `[[:space:]]` matches ASCII spaces (space, tab, newline, etc) and Unicode characters in the Space category ([1]). However, there are other space-like characters not in the Space category. This includes U+200B (Zero-Width Space), and many more. It turns out the "Default ignorable code points" [2][3] are what we're after. These are the set of 400 or so formatting and control characters that are invisible when displayed. Note that there are other control characters that aren't invisible when rendered, instead they're shown with a placeholder glyph. These include the ASCII C0 and C1 control codes [4], certain Unicode control characters [5], and unassigned, reserved, and private use codepoints. There is one outlier: the Braille pattern blank (U+2800) [6]. This character is visually blank, but is not considered to be a space or an ignorable code point.

Quickstart
Run this to start a basic Danbooru instance:
curl -sSL https://raw.githubusercontent.com/danbooru/danbooru/master/bin/danbooru | sh
This will install Docker Compose and use it to start Danbooru. When it's done, Danbooru will be running at http://localhost:3000.
Alternatively, if you already have Docker Compose installed, you can just do:
wget https://raw.githubusercontent.com/danbooru/danbooru/master/docker-compose.yaml
docker-compose up
Manual Installation
Follow the INSTALL.debian script to install Danbooru.
The INSTALL.debian script is written for Debian, but can be adapted for other distributions. Danbooru has been successfully installed on Debian, Ubuntu, Fedora, Arch, and OS X. It is recommended that you use an Ubuntu-based system since Ubuntu is what is used in development and production.
See here for a guide on how set up Danbooru inside a virtual machine.
For best performance, you will need at least 256MB of RAM for PostgreSQL and Rails. The memory requirement will grow as your database gets bigger.
In production, Danbooru uses PostgreSQL 10.18, but any release later than this should work.
Troubleshooting
If your setup is not working, here are the steps I usually recommend to people:
-
Test the database. Make sure you can connect to it using
psql. Make sure the tables exist. If this fails, you need to work on correctly installing PostgreSQL, importing the initial schema, and running the migrations. -
Test the Rails database connection by using
bin/rails console. RunPost.countto make sure Rails can connect to the database. If this fails, you need to make sure your Danbooru configuration files are correct. -
Test Nginx to make sure it's working correctly. You may need to debug your Nginx configuration file.
-
Check all log files.
