2.0: Rewrite data.js
This fixesjquery/testswarm#197. These are currently removed from
the TestSwarm injector, however this is jQuery specific, and
should be done from this end instead.
* Removed inline usage of QUnit.reset() because it is messing with the
expectation model as reset does .empty() which does a recursive cleanData
on everything in #qunit-fixture, so any expectJqData above .reset() would
fail negatively.
Instead of calling reset inline, either updated the following assertions to
take previous assertions' state into account, or broke the test() up into
2 tests at the point where it would call QUnit.reset.
* After introducing the new memory leak discovery a whole bunch of tests were
failing as they didn't clean up everything. However I didn't (yet) add
QUnit.expectJqData calls all over the place because in most if not all of
these cases it is valid data storage. For example in test "data()", there
will be an internal data key for "parsedAttrs". This particular test isn't
intending to test for memory leaks, so therefor I made the new discovery
system only push failures when the test contains at least 1 call to
QUnit.expectJqData.
When not, we'll assume that whatever data is being stored is acceptable
because the relevant elements still exist in the DOM anyway (QUnit.reset
will remove the elements and clean up the data automatically).
I did add a "Always check jQuery.data" mode in the test suite that will
trigger it everywhere. Maybe one day we'll include a call to everywhere,
but for now I'm keeping the status quo: Only consider data left in storage
to be a problem if the test says so ("opt-in").
* Had to move #fx-tests inside the fixture because ".remove()" test would
otherwise remove stuff permanently and cause random other tests to fail
as "#hide div" would yield an empty collection.
(Why wasn't this in the fixture in the first place?)
As a result moving fx-tests into the fixture a whole bunch of tests failed
that relied on arbitrary stuff about the document-wide or fixture-wide
state (e.g. number of divs etc.). So I had to adjust various tests to
limit their sample data to not be so variable and unlimited...
* Moved out tests for expando cleanup into a separate test.
* Fixed implied global variable 'pass' in effects.js that was causing
"TypeError: boolean is not a function" in *UNRELATED* dimensions.js that
uses a global variable "pass = function () {};" ...
* Removed spurious calls to _removeData. The new test exposed various failures
e.g. where div[0] isn't being assigned any data anyway.
(queue.js and attributes.js toggleClass).
* Removed spurious clean up at the bottom of test() functions that are
already covered by the teardown (calling QUnit.reset or removeClass to
supposedly undo any changes).
* Documented the parentheses-less magic line in toggleClass. It appeared that
it would always keep the current class name if there was any (since the
assignment started with "this.className || ...".
Adding parentheses + spacing is 8 bytes (though only 1 in gzip apparently).
Only added the comment for now, though I prefer clarity with logical
operators, I'd rather not face the yayMinPD[1] in this test-related commit.
* Updated QUnit urlConfig to the new format (raw string is deprecated).
* Clean up odd htmlentities in test titles, QUnit escapes this.
(^\s+test\(.*)(>\;) → $1>
(^\s+test\(.*)(<\;) → $1<

* Clean up testinit and testrunner
* Uncomment isLocal (at least make sure it is declared)
* Rephrase environment assertions to make sense if one reads
them when they pass.
* Optimise an expensive loop that might be the cause of this

- Replaced all the $ for jQuery in the tests and suite.
- Added a noConflict to testrunner.js.
- Modified the test for noConflict() so that it still work.
- Added jQuery 1.2.1 and 1.2.3 to otherlibs.
Plugins will be most interested in:
- jQuery.data(elem) -> Unique ID for the element
- jQuery.data(elem, name) -> Named data store for the element
- jQuery.data(elem, name, value) -> Saves a value to the named data store
- jQuery.removeData(elem) -> Remove the expando and the complete data store
- jQuery.removeData(elem, name) -> Removes just this one named data store
jQuery's .remove() and .empty() automatically clean up after themselves. Once an element leaves a DOM document their events are no longer intact. Thus, statements like so:
{{{
$("#foo").remove().appendTo("#bar");
}}}
should be written like so:
{{{
$("#foo").appendTo("#bar");
}}}
in order to avoid losing the bound events.
