Steps to reproduce:

On a template variable with multi-select:

  1. enter a search which matches one or more items
  2. navigate by keyboard to an item
  3. use space bar to toggle the item

Actual Result:
The space bar input is appended or prepended to the search text.

Expected Result
The search text should remained unchanged, since focus is on a dropdown item.

Feature Request

Is your feature request related to a problem? Please describe:

This is a really minor nit, but the EXPLAIN output on binary strings is different from what I expected:

CREATE TABLE t1 (
 id INT NOT NULL PRIMARY KEY auto_increment,
 b varchar(255) not null,
 c varbinary(255) not null,
 index (b),
 index (c)
);


INSERT INTO t1 (b,c) VALUES ('a', 'a'),('b

I am making a health check endpoint for kubernetes (google cloud's service to host containerized applications) for my mySql application.

right now I am using this package https://www.npmjs.com/package/health-check-mysql

But is there something built into the package itself, something like a isConnected method. ie:
connection.isConnected() ? throw new Error('not connected to mysql') : null

Sometimes it is needed to store compressed data in the DB. Unfortunately not all the DBs have built-in compression and FUSE compressed FSes are not available for every OS. So it may make sense to store compressed binary blobs in the DB.

Unfortunately when one sees them in DBeaver he sees them compressed, but often they are needed uncompressed. So it'd be nice to have a feature to decompress the

I learned this by digging through the code base for a while, and uncovered:

https://github.com/matomo-org/matomo/blob/a345c2f22b8356dd3300d66f5ade3df24f69d900/core/Config.php#L149-L151

From which I deduce that in the same directory where I might have a config/config.ini.php file, I can also have a config/blog.example.org.config.ini.php file - which, if it exists will be used instead.

Multi-line queries have a prompt_continuation (or not currently, due to issue 681, but that's beside the point). But even with prompt_continuation set to an empty string, it starts the next line indented, even when it's just due to wrapping at the edge of the terminal window:

db> select "example text that wraps onto the nex

I often copy/paste my query fr

Not really an issue, but rather another use of the tool that could be advertised in the documentation.

We have slaves that have discrepancies (missing rows, rows with some different values) as highlighted by a very long run of pt-table-checksum. We tried fixing these tables with pt-table-sync with no success.

By running gh-ost on a master using RBR (does not work with statement based replica

Let's support at least reading "b3" header from a single string, most commonly traceid-spanid-1
It would also be nice to support optionally writing this, especially in message providers or others with constrained environments.

Expected behavior

As discussed on openzipkin/b3-propagation#21 and first implemented here: https://github.com/openzipkin/brave/blob/master/brave/src/main/java/bra

We already have most of our Directus API 2.x endpoints/params within Paw for testing. We could finish adding all of these and then potentially use their code generators to create SDKs for our secondary languages.

We also have a Swagger file for 98% of API 1.1 — so we could update that (and make sure that OpenAPI allows for our filteri

In the tutorial events there is this example:

const User = bookshelf.model('User', {
  tableName: 'users',

  initialize() {
    this.on('saving', (model) => {
      return User.forge({email: model.get('email')}).fetch().then((user) => {
        if (user) 
            throw new Error('That email address already exists')
