Rails 6.0 introduces parallel testing and the default degree of parallelism is configured based on the number of CPU.
refer https://github.com/rails/rails/pull/34735https://github.com/rails/rails/pull/31900
When any minitest executed under the OS where 2 or more CPU available,
SQLite 3 database files are not git-ignored.
Also updated other files which ignores SQLite database files.
* Steps to reproduce
```
$ git clone https://github.com/yahonda/rep_ignore_sqlite3_databases.git
$ cd rep_ignore_sqlite3_databases/
$ bin/rails test
$ git status
```
* Expected behavior:
- No `Untracked files:`
* Actual behavior:
- SQLite 3 database files appeared
```
$ git status
On branch master
Untracked files:
(use "git add <file>..." to include in what will be committed)
db/test.sqlite3-0
db/test.sqlite3-1
db/test.sqlite3-2
db/test.sqlite3-3
db/test.sqlite3-4
db/test.sqlite3-5
nothing added to commit but untracked files present (use "git add" to track)

In most cases it works now without explicit require because it's accidentally required through
active_support/core_ext/date_and_time/calculations.rb where we still call `try`,
but that would stop working if we changed the Calculations implementation and remove the require call there.
Fixes that file attachments without captions would not be represented in plain text generated from rich-text content, causing ActionText::RichText#present? to return false.
Closes#36607.
Assigning a has_one association for a persisted record saves the change immediately, so attempting to read a rich-text attribute on a persisted record without a corresponding ActionText::RichText would eagerly create one. Avoid assigning the rich text association to fix.
If the [`action_text.helper` initializer][0] runs after
`ActionController::Base` has been loaded, but before the
`rails-html-sanitizer` gem has been `require`d, then the reference to
the constant `Rails::Html` in the body of the
`ActionText::ContentHelper` module raises an `uninitialized constant`
exception.

I implemented Foreign key create in `create_table` for SQLite3 at
#24743. This follows #24743 to implement `add_foreign_key` and
`remove_foreign_key`.
Unfortunately SQLite3 has one limitation that
`PRAGMA foreign_key_list(table-name)` doesn't have constraint name.
So we couldn't implement find/remove foreign key by name for now.
Fixes#35207.
Closes#31343.
In MySQL, the text column size is 65,535 bytes by default (1 GiB in
PostgreSQL). It is sometimes too short when people want to use a text
column, so they sometimes change the text size to mediumtext (16 MiB) or
longtext (4 GiB) by giving the `limit` option.
Unlike MySQL, PostgreSQL doesn't allow the `limit` option for a text
column (raises ERROR: type modifier is not allowed for type "text").
So `limit: 4294967295` (longtext) couldn't be used in Action Text.
I've allowed changing text and blob size without giving the `limit`
option, it prevents that migration failure on PostgreSQL.
The Action Text installations appends `require("trix")` to the application.js file. The problem is that there isn't a line break in the beginning of the installation output, leading to syntax errors, e.g.:
```
import './application.scss'require("trix")
```
This commit moves the line break from the end to the beginning of the output, fixing it to:
```
import './application.scss'
require("trix")
```
Failing test before the ActionText::RichText change:
```
Error:
ActionText::ModelTest#test_embed_extraction_only_extracts_file_attachments:
ArgumentError: Could not find or build blob: expected attachable, got #<ActionText::Attachables::RemoteImage:0x00007fb0259fef70 @url="http://example.com/cat.jpg", @content_type="image", @width=nil, @height=nil>
```
After 866da19fd9fc12d001ab99ac87890ea1cebb2cd9 we now use package.json
to install Action Text's JS dependencies (see JS_PACKAGE_PATH).
But when the gem pacakge for Action Text is built, package.json was not
included so running `rails action_text:install` in a Rails app would
fail with:
```
rails action_text:install
rails aborted!
Errno::ENOENT: No such file or directory @ rb_sysopen - xxx/gems/actiontext-6.0.0.alpha/lib/templates/../../package.json
./bin/rails:4:in `<main>'
