Set MaxIdleConn and MaxOpenConn when using the GF_DATABASE_URL configuration. Also added GF_DATABASE_DEBUG flag to print SQL statements and SQL execution times.
See #9784 for the details.
At least in my Postgresql 9.6.5, the old syntax of capitalized queries doesn't work (Linux).<br>
Running with UTF-8 as standard encoding and the ` notations didn't work either, so removed those.

If a dashboard has a null value for updated_by then the migration
for the dashboard version table fails. This change uses coalesce to
set -1 instead of null when inserting into the created_by column
which has a non-null constraint. Fixes#8783.
A simple version control system for dashboards. Closes#1504.
Goals
1. To create a new dashboard version every time a dashboard is saved.
2. To allow users to view all versions of a given dashboard.
3. To allow users to rollback to a previous version of a dashboard.
4. To allow users to compare two versions of a dashboard.
Usage
Navigate to a dashboard, and click the settings cog. From there, click
the "Changelog" button to be brought to the Changelog view. In this
view, a table containing each version of a dashboard can be seen. Each
entry in the table represents a dashboard version. A selectable
checkbox, the version number, date created, name of the user who created
that version, and commit message is shown in the table, along with a
button that allows a user to restore to a previous version of that
dashboard. If a user wants to restore to a previous version of their
dashboard, they can do so by clicking the previously mentioned button.
If a user wants to compare two different versions of a dashboard, they
can do so by clicking the checkbox of two different dashboard versions,
then clicking the "Compare versions" button located below the dashboard.
From there, the user is brought to a view showing a summary of the
dashboard differences. Each summarized change contains a link that can
be clicked to take the user a JSON diff highlighting the changes line by
line.
Overview of Changes
Backend Changes
- A `dashboard_version` table was created to store each dashboard
version, along with a dashboard version model and structs to represent
the queries and commands necessary for the dashboard version API
methods.
- API endpoints were created to support working with dashboard
versions.
- Methods were added to create, update, read, and destroy dashboard
versions in the database.
- Logic was added to compute the diff between two versions, and
display it to the user.
- The dashboard migration logic was updated to save a "Version
1" of each existing dashboard in the database.
Frontend Changes
- New views
- Methods to pull JSON and HTML from endpoints
New API Endpoints
Each endpoint requires the authorization header to be sent in
the format,
```
Authorization: Bearer <jwt>
```
where `<jwt>` is a JSON web token obtained from the Grafana
admin panel.
`GET "/api/dashboards/db/:dashboardId/versions?orderBy=<string>&limit=<int>&start=<int>"`
Get all dashboard versions for the given dashboard ID. Accepts
three URL parameters:
- `orderBy` String to order the results by. Possible values
are `version`, `created`, `created_by`, `message`. Default
is `versions`. Ordering is always in descending order.
- `limit` Maximum number of results to return
- `start` Position in results to start from
`GET "/api/dashboards/db/:dashboardId/versions/:id"`
Get an individual dashboard version by ID, for the given
dashboard ID.
`POST "/api/dashboards/db/:dashboardId/restore"`
Restore to the given dashboard version. Post body is of
content-type `application/json`, and must contain.
```json
{
"dashboardId": <int>,
"version": <int>
}
```
`GET "/api/dashboards/db/:dashboardId/compare/:versionA...:versionB"`
Compare two dashboard versions by ID for the given
dashboard ID, returning a JSON delta formatted
representation of the diff. The URL format follows
what GitHub does. For example, visiting
[/api/dashboards/db/18/compare/22...33](http://ec2-54-80-139-44.compute-1.amazonaws.com:3000/api/dashboards/db/18/compare/22...33)
will return the diff between versions 22 and 33 for
the dashboard ID 18.
Dependencies Added
- The Go package [gojsondiff](https://github.com/yudai/gojsondiff)
was added and vendored.
