The fix covers two places:
- The Redis session.
- The Redis cache store.
The PHP Redis has the option to establish the connection using TLS/SSL instead of using the "tls://" prefix.
This is done to ensure consistency with the Redis cluster connection,
as the code for both single and cluster connections is located in one place.
The changes here are heterogeneous:
- Include stuff that is not available (other test has included it).
Sometimes local to a unit test, others in setupBeforeClass() or
globally, ... depends on every case.
- Rename some tests (namespaces, test name, ...) towards getting it
running.
- Amend small bits here and there.
Important note: I've left any "cosmetic" warning out from the
changes, only a few errors (like long array syntax) have been fixed.
There are a few tests in core that are commented since the
beginning. That's not useful at all, so with this commit we
are un-commenting them instead.
Note that this is an initial step to have them back with skipped
outcome. Later in this issue we'll decide about to keep them or
completely remove them (each test can have a different outcome).
Where calling code was previously using either the 32-bit limit, or a
value equal to SQL_INT_MAX inside a database read/write, instead use
our new constant.
There are inherent issues with task blocking which mean that it has
never worked properly. It is also very buggy and can lead to massive
performance issues with task processing.
It is almost impossible to deprecate this in a staged fashion because
various APIs use the methods and it is not possible to determine which
are API uses and which are other valid uses.
In reality there has been little-to-no uptake on the use of this feature
and it should just be removed.
* An image with non-empty alt text should not have a presentation role.
* An empty alt attribute is sufficient for decorative images. No need to
add a presentation role for them.
* Additionally, if there is already text that is present for an image,
there's no need to add an alt text with the same text. Such images are
decorative and should just have an empty alt text.
Also added @runInSeparateProcess on each session Redis cluster test to let the test run
in a separate process to avoid the error "the headers are not already sent" by PHPUnit.
