WordPress returns an error on the line where I call get_error_codes():
add_filter( 'login_errors', function( $error ) {
global $errors;
//var_dump($errors);
$err_codes = $errors->get_error_codes();
$error = 'Message here.';
return $error;
});
Here is the full error message:

I am trying to understand what is happening here. Is the WooCommerce apply_filters on 'login_errors' not allowing me to do this?

When I login to the backend of my site and I click either the content tab or the people tab I get the error "The website encountered an unexpected error. Please try again later". I have not altered any core code on the site just the frontend theme. My thinking is that Drupal needs updating to the latest version as it is currently on 8.2.5 and some of the plugins are not up-to-date.
I tried updating Drupal and the site crashed, I have also updated a couple of modules but 2 of them wouldn't update and they were: https://www.drupal.org/project/metatag or https://www.drupal.org/project/twig_extender.
Here is the PHP error message:

It seems you have issue with Drupal core updates.
The problem is this:
Argument 2 passed to Drupal\views\Entity\Render\EntityFieldRenderer::render() must be an instance of Drupal\views\Plugin\views\field\Field, instance of Drupal\views\Plugin\views\field\EntityField given
That plugin got renamed from Field to EntityField. See #2408667: Rename Field.php to EntityField.php. But that only got committed to 8.3.x, so something seems to have gone wrong during your update to 8.2.5. Some shuffling between 8.3 and 8.2? Can you try running the update again?
Take a look here for details: https://www.drupal.org/node/2848227
Loop.times(5, () -> {
System.out.println("looping");
});
Which of these would it effectively compile to?
for(int i = 0; i < 5; i++)
System.out.println("looping");
or something like
new CallableInterfaceImpl(){
public void call(){
for(int i = 0; i < 5; i++)
System.out.println("looping");
}
}.call();
So would it replace (kind of inline), or actually create an anonymous class?
The VM decides how to implement lambda, not a compiler.
See Translation strategy section in Translation of Lambda Expressions.
Instead of generating bytecode to create the object that implements the lambda expression (such as calling a constructor for an inner class), we describe a recipe for constructing the lambda, and delegate the actual construction to the language runtime. That recipe is encoded in the static and dynamic argument lists of an invokedynamic instruction.
for construction from your example is most effective way in terms of simple compiling or perfomance (but the performance differences are very small, by the tests).
Addon:
I created and disassemble two examples:
for (String string: Arrays.asList("hello")) {
System.out.println(string);
}

Compiler generated class-file is more complicated and larger (771b vs 1262b) for Lambda example.
Java compiler will generate synthetic methods for the code construct that is neither explicitly nor implicitly declared.
As we are aware, lambda expression/function is an anonymous class method implementation for abstract method in functional interface and if we see the byte code of a compiled class file with lambda expression, Instead of creating a new object that will wrap the Lambda function, it uses the new INVOKEDYNAMIC instruction to dynamically link this call site to the actual Lambda function which is converted to private static synthetic lambda$0(Ljava/lang/String;)V which will accept string as a parameter.
private static synthetic lambda$0(Ljava/lang/String;)V
GETSTAIC java/lang/System.out: Ljava/io/PrintStream;
ALOAD 0
INVOKEVIRTUAL java/io/PrintStream.println(Ljava/lang/String;)V
RETURN
Example: list.forEach(x-> System.out.println(x));
This lambda expression x-> System.out.println(x) is converted to private static synthetic block as mentioned above. But how this will be invoked for each element in the list when we run java Class? Refer the below byte code of lambda expression linkage as forEach accepts Consumer functional interface object.
INVOKEDYNAMIC accept()Ljava/util/function/Consumer;
[
java/lang/invoke/LambdaMetaFactory.metafactory(Ljava/lang/invokeMethodHandler$Lookup.Ljava/lang/invoke/CallSite..
//arguments
(Ljava/lang/Object;)V
//INVOKESTATIC
com/<Classname>.lambda$)(Ljava/lang/String;)V,
(Ljava/lang/String;)V
]
java.lang.invoke.LambdaMetaFactory: This class provides two forms of linkage methods:
A standard version (metafactory(MethodHandles.Lookup, String, MethodType, MethodType, MethodHandle, MethodType)) using an optimized protocol,
An alternate version altMetafactory(MethodHandles.Lookup, String, MethodType, Object...)).
These linkage methods are designed to support the evaluation of lambda expressions and method references in the Java Language.
For every lambda expressions or method reference in the source code, there is a target type which is a functional interface.
Evaluating a lambda expression produces an object of its target type. The recommended mechanism for evaluating lambda expressions is to desugar the lambda body to a method, invoke an invokedynamic call site whose static argument list describes the sole method of the functional interface and the desugared implementation method, and returns an object (the lambda object) that implements the target type.
Note(For method references, the implementation method is simply the referenced method; no desugaring is needed.)
I've started writing Acceptance Tests with Behat, Mink Extension, Selenium 2 and Symfony. I've followed the instructions, which can be seen here: http://extensions.behat.org/mink/
If i want to start my first feature with "./bin/behat" it says:
christian#christian-VirtualBox:/var/www/wiglee$ ./bin/behat
Feature: User Registration
In order to use ProjectNameHere
As a user
I should be able to register
#javascript
Scenario: User Registration # features/user.registration.feature:7
Given I register as "test#test.com" # InheritedFeatureContext::registerAs()
Could not open connection
And I logout # InheritedFeatureContext::logout()
1 scenario (1 failed)
2 steps (1 skipped, 1 failed)
I started the selenium server, and the output tells me the connection should be okay:
INFO: Got a request to create a new session: {platform=ANY, browserVersion=8, browserName=firefox, deviceType=tablet, name=Behat test, selenium-version=2.31.0, browser=firefox, deviceOrientation=portrait, version=8, max-duration=300}
How i started Selenium Hub:
java -jar ./selenium-server-standalone-2.39.0.jar -role hub
How i added a Selenium Node (without the '.' between local and host):
java -jar ./selenium-server-standalone-2.39.0.jar -role node -hub http://local.host:4444/grid/register

I recently fought the same issue and managed to get it working with selenium grid.
The issue in my case was related to default capabilities Mink sends. The hub tries to find a proper node to run, which would accept requested capabilities. In my case issue was a browser version. It finally worked when I set it to an empty string:
# behat.yml
default:
extensions:
Behat\MinkExtension\Extension:
base_url: 'http://localhost/'
browser_name: phantomjs
selenium2:
wd_host: http://127.0.0.1:4444/wd/hub
capabilities:
version: ''
