Commands executed on Mink elements may fail for several reasons.
ElementWrapper is introduced to automatically handle some of those
situations, like StaleElementReference exceptions and ElementNotVisible
exceptions.
StaleElementReference exceptions are thrown when the command is executed
on an element that is no longer attached to the DOM. When that happens
the ElementWrapper finds again the element and executes the command
again on the new element.
ElementNotVisible exceptions are thrown when the command requires the
element to be visible but the element is not. When that happens the
ElementWrapper waits for the element to be visible before executing the
command again.
These changes are totally compatible with the current acceptance tests.
They just make the tests more robust, but they do not change their
behaviour. In fact, this should minimize some of the sporadic failures
in the acceptance tests caused by their concurrent nature with respect
to the web browser executing the commands.
However, the ElementWrapper is not a silver bullet; it handles the most
common situations, but it does not handle every possible scenario. For
example, the acceptance tests would still fail sporadically if an
element can become staled several times in a row (uncommon) or if it
does not become visible before the timeout expires (which could still
happen in a loaded system even if the components under test work right,
but obviously it is not possible to wait indefinitely for them).

Starting a session for an Actor can fail, typically, due to a timeout
connecting with the web browser. Now if the session fails to start it
will be tried again up to "actorTimeoutMultiplier" times in total before
giving up.

The timeout passed to the "find" method was multiplied by the
"findTimeoutMultiplier" attribute. However, as "find" used
"findAncestor" and "findAncestor", in turn, used "find" itself the
timeout was increased exponentially for ancestor elements. Now "find"
was split in "find" and "findInternal"; the first method is the public
one and modifies the given parameters as needed and then calls the
second method, private, that performs the find itself.

The "named" Mink selector first tries to find an exact match for its
locator and then, if not found, tries to find a partial match. Besides
other harder to track problems (see comment in the commit in which the
"content" locator was removed), this could cause, for example, finding
an action link titled "Favorited" when looking for the action link
titled "Favorite" (that is, one that conveys the opposite state to the
one found).
Although currently all the acceptance tests are compatible with both the
"named" and the "named_exact" Mink selectors the predefined locators are
modified to use the "named_exact" Mink selector to make them more
future-proof; the "named" Mink selector can still be used if needed
through the "customSelector" method in the builder object.

The "content" locator uses the "named" Mink selector and the "content"
Mink locator to find the element. The "named" Mink first tries to find
the elements whose content match exactly the given content but, if none
is found, then it tries to find elements that just contain the given
content.
This behaviour can lead to hard to track issues. Finding the exact match
and, if not found, finding the partial match is done in quick
succession. In most cases, when looking for an exact match the element
is already there, it is returned, and everything works as expected. Or
it may not be there, but then it is not there either when finding the
partial match, so no element is returned, and everything works as
expected (that is, the actor tries to find again the element after some
time).
However, it can also happen that when looking for an exact match there
is no element yet, but it appears after trying to find the exact match
but before trying to find the partial match. In that situation the
desired element would be returned along with its ancestors. However, as
only the first found element is taken into account and the ancestors
would appear first the find action would be successful, but the returned
element would not be the expected one. This is highly unlikely, yet
possible, and can cause sporadic failures in acceptance tests that,
apparently, work as expected.
Using a "named_exact" Mink selector instead of the "named" Mink selector
does not provide the desired behaviour in most cases either. As it finds
any element whose content matches exactly the given content, looking for
"Hello world" in "<div><p><a>Hello world</a></p></div>" would match the
"div", "p" and "a" elements; in that situation the "div" element would
be the one returned, when typically the "a" element would be the
expected one.
As it is error prone and easily replaceable by more robust locators the
"content" locator was removed from the predefined ones (although it can
still be used if needed through the "customSelector" method in the
builder object).

Currently, when disabling the brute force protection no new brute force attempts are logged. However, the ones logged within the last 24 hours will still be used for throttling.
This is quite an unexpected behaviour and caused some support issues. With this change when the brute force protection is disabled also the existing attempts within the last 24 hours will be disregarded.

This implements the basics for the new app-password based authentication flow for our clients.
The current implementation tries to keep it as simple as possible and works the following way:
1. Unauthenticated client opens `/index.php/login/flow`
2. User will be asked whether they want to grant access to the client
3. If accepted the user has the chance to do so using existing App Token or automatically generate an app password.
If the user chooses to use an existing app token then that one will simply be redirected to the `nc://` protocol handler.
While we can improve on that in the future, I think keeping this smaller at the moment has its advantages. Also, in the
near future we have to think about an automatic migration endpoint so there's that anyways :-)
If the user chooses to use the regular login the following happens:
1. A session state token is written to the session
2. User is redirected to the login page
3. If successfully authenticated they will be redirected to a page redirecting to the POST controller
4. The POST controller will check if the CSRF token as well as the state token is correct, if yes the user will be redirected to the `nc://` protocol handler.
This approach is quite simple but also allows to be extended in the future. One could for example allow external websites to consume this authentication endpoint as well.

The plain text password for a shared links was hashed and, then, the
hashed password was hashed again and set as the final password. Due to
this the password introduced in the "Authenticate" page for the shared
link was always a wrong password, and thus the file could not be
accessed.

While the risk is actually quite low because one would already have the user session and could potentially do other havoc it makes sense to throttle here in case of invalid previous password attempts.

This makes the new `@BruteForceProtection` annotation more clever and moves the relevant code into it's own middleware.
Basically you can now set `@BruteForceProtection(action=$key)` as annotation and that will make the controller bruteforce protected. However, the difference to before is that you need to call `$responmse->throttle()` to increase the counter. Before the counter was increased every time which leads to all kind of unexpected problems.

This allows adding rate limiting via annotations to controllers, as one example:
```
@UserRateThrottle(limit=5, period=100)
@AnonRateThrottle(limit=1, period=100)
```
Would mean that logged-in users can access the page 5 times within 100 seconds, and anonymous users 1 time within 100 seconds. If only an AnonRateThrottle is specified that one will also be applied to logged-in users.

This is not intended anymore, since it falls back to force english
when the header is not set. Also 0228bc6e66
makes clear that the order should be:
1. User setting
2. Accept language
3. Admin default
This is the case since the commit from above, unless via OCS and DAV.
Both forced to accept-language falling back to english.
By removing the force, it now also matches the w3 priority list:
