* Failing test
* Fix underlying problem
* Less naive fix
Now we make sure we maintain the sort order of the titles array when adding a new tiddler
* Fix failing tests
* Refactor filter tests to repeat them with different store orderings
* Revert "Fix failing tests"
This reverts commit ee03ee57f5.
* Refine fix to retain stylesheet ordering
The order of tiddlers in the HTML file uses localeCompare(), and that determines the insertion order. So if we want to be compatible with older versions we have to use localeCompare() to order tiddlers, not a plain sort()
* Don't sort shadow tiddlers
Instead rely on the existing ordering
* Fix failing tests, take 2
I think that all of these changes are explained by the store no longer retaining insertion order, but now using localecompare ordering
* Fix tests from #6327
* First pass at modular wiki indexes
An exploratory experiment
* Fix tests
* Faster checking for existence of index methods
We don't really need to check the type
* Use the index for the has operator
* Fix typo
* Move iterator index methods into indexer modules
Now boot.js doesn't know the core indexers
* Fix up the other iterator index functions
* Fix crash with missing index branch
* Limit the field indexer to values less than 128 characters
* Fallback to the old manual scan if the index method returns null
* Sadly, we can no longe re-use the field indexer to accelerate the `has` operator, because the index now omits tiddlers that have field values longer than the limit
Still need to make the index configuration exposed somehow
* Rearrange tests so that we can test with and without indexers
We also need to expose the list of enabled indexers as a config option
* Test the field indexer with different length fields
So that we test the indexed and non-indexed codepaths
* Added better handling for sortByList manual placements
If manual placement specifications show up in an inconvenient order,
sortByList, will go to the trouble of processing them in that order.
* Added tests to confirm solution to (#3296)
...That custom tag ordering will not choke when tiddlers get sorted after their dependencies have been placed around them
* Corrected list-after bug when referencing external titles
* Using more error-proof $tw.utils.hop in sortByList
* minor indentation correction in test-tags.js
