This reverts commit 22bc12ec374b8bdeb3818ca0a3eb787dd3ce39d8.
REASON: We will remove the MiniTest::Spec from Rails and we need these
methods again
Conflicts:
activesupport/lib/active_support/test_case.rb
Tagging every message in tests makes the logs really wide. It's great
for grepping, but annoying to open in an editor or a narrow terminal.
Try out a different approach: spit out a heading before each test.
The AS utility silence_warnings does not really silence this
one, because it is issued at parse-time. It seemed to in
some places because the constant was the only expression in
the block and therefore it was its return value, that could
potentially be used by silence_warnings are return value of
the yield call.
To bypass the warning we assign to a variable. The chosen
variable is "_" because it is special-cased in parse.c not
to issue an "assigned but unused variable" warning in turn.
Three basic refactors in this PR:
* We extracted the logic into a method object. We now don't define a tone of extraneous methods on Hash, even if they were private.
* Extracted blocks of the case statement into methods that do the work. This makes the logic more clear.
* Extracted complicated if clauses into their own query methods. They often have two or three terms, this makes it much easier to see what they _do_.
We took care not to refactor too much as to not break anything, and put comments where we suspect tests are missing.
We think ActiveSupport::XMLMini might be a good candidate to move to a plugin in the future.
When you add one callack in two separate `set_callback` calls - it is
only called once.
When you do it in one `set_callback` call - it is called twice.
This violates the principle of least astonishment for me. Duplicating
callback is usually an error. There is a correct and obvious way to do
anything without this "feature".
If you want to do
before_save :clear_balance, :calculate_tax, :clear_balance
or whatever, you should better do
before_save :carefully_calculate_tax
def carefully_calculate_tax
clear_balance
calculate_tax
clear_balance
end
And this even opens gates for some advanced refactorings, unlike the
first approach.
My assumptions are:
- Principle of least astonishment is violated, when callbacks are either
prevented from duplication, or not.
- Duplicating callbacks is usually an error. When it is intentional -
it's a smell of a bad design and can be approached without abusing
this "feature".
My suggestion is: do not allow duplicating callbacks in one callback
call, like it is not allowed in separate callbacks call.
The encoding scheme (e.g. ☠ -> "\u2620") was broken for characters
not in the Basic Multilingual Plane. It is possible to escape them
for json using the weird encoding scheme of a twelve-character
sequence representing the UTF-16 surrogate pair (e.g. '𠜎' ->
"\u270e\u263a") but this wasn't properly handled in the escaping code.
Since raw UTF-8 is allowed in json, it was decided to simply pass
through the raw bytes rather than attempt to escape them.
Summary of the changes:
* Add thread_safe gem.
* Use thread safe cache for digestor caching.
* Replace manual synchronization with ThreadSafe::Cache in Relation::Delegation.
* Replace @attribute_method_matchers_cache Hash with ThreadSafe::Cache.
* Use TS::Cache to avoid the synchronisation overhead on listener retrieval.
* Replace synchronisation with TS::Cache usage.
* Use a preallocated array for performance/memory reasons.
* Update the controllers cache to the new AS::Dependencies::ClassCache API.
The original @controllers cache no longer makes much sense after @tenderlove's
changes in 7b6bfe84f3 and f345e2380c.
* Use TS::Cache in the connection pool to avoid locking overhead.
* Use TS::Cache in ConnectionHandler.
