In 4.1 [30240], `wp_insert_term()` was modified to allow the creation of terms
with duplicate slugs, as long as the terms are in different taxonomies.
`wp_update_term()` didn't get the corresponding modification, with the result
that term updates fail when the term being updated shares a slug with an older
term, regardless of that older term's taxonomy.
Props ipm-frommen.
Fixes#30780 for trunk.

This is a revert of [30494], [30492], [30347], and [30334]. The latter
changeset was a revert of [30336], which was a revert of [30241].
Watch for Term Splitting, Version III in version 4.2, coming soon to a
WordPress trunk near you.
See #30335, #5809.

Originally introduced in [30241] and reverted in [30336], term splitting is
back and better than ever. Now with *more unit tests* and *improved treatment
of child terms*!
See #30335.

Splitting shared terms means assigning a new term_id to a given term_taxonomy_id.
It was uncovered that this change could cause problems for sites that have
cached the original term_id somehow - say, in postmeta - since future lookups
using that term_id will now fail.
Removing for 4.1-beta1. We'll look at improvements to backward compatibility
to try to get this back into a later beta.
Props mboynes.

When updating an existing taxonomy term that shares its `term_id` with
another term, we generate a new row in `wp_terms` and associate the updated
term_taxonomy_id with the new term. This separates the terms, such that
updating the name of one term does not change the name of any others.
Note that this term splitting only occurs on installations whose database
schemas have been upgraded to version 30133 or higher. Note also that shared
terms are only split when run through `wp_update_term()`, as on edit-tags.php;
we will wait until a future release of WordPress to force the splitting of all
shared taxonomy terms.

Fixes#5809.

A "shared" term occurs when two entries in the `wp_term_taxonomy` table share a
single `term_id`, and thereby correspond to the same row in `wp_terms`. This
changeset stops the practice of creating shared terms: each new row in
`wp_term_taxonomy` will receive its own row in `wp_terms`. The new strategy
for term creation depends on whether the installation's database schema is up
to date for 4.1:
* If so, terms are allowed to be created with the same slug as an existing term, as long as they are in different taxonomies and do not share a parent. Thus, a new tag with the slug 'wordpress' can exist alongside a category with the slug 'wordpress'.
* If not, new terms will be forced to have unique slugs. Thus, on an installation containing a category with the slug 'wordpress', a new tag 'WordPress' will get the slug 'wordpress-2'.
Fixes#21950. See #5809.

This change brings return values for failures of this sort in line with other
failed lookups in term_exists(): a null value is now returned in all cases
where the queried term is not found.
Adds unit test for the sanitization issue. Modifies existing unit test to
reflect the change in return value for empty term strings.
Props boonebgorges, georgestephanis.
Fixes#29589.
git-svn-id: https://develop.svn.wordpress.org/trunk@29865 602fd350-edb4-49c9-b593-d223f7449a82
Passing a 0 (or '0') as the 'parent' param of term_exists() should limit
results to terms with no parent.
Adds unit test.
Fixes#29851.

Using get_term_by() rather than direct SQL queries to fetch the alias term
fixes a number of issues:
* Object cache for aliased term is properly cleared after update.
* If the aliased term is in the object cache, it's served from there, saving a database query.
* Duplicate 'edit_terms' and 'edited_terms' hooks can be removed.
* Fix a PHP notice when the 'alias_of' term is not found.
* Prevent the incorrect creation of a new term group for the primary term when the 'alias_of' term is not found.
Adds unit tests for 'alias_of' functionality in both functions.
Fixes#29848.

These include an exhaustive set of tests for term_exists(), as well as tests
for wp_insert_term() that demonstrate failure when attempting to create a
duplicate term.
Props simonwheatley for an initial patch.
See #22023.

There will be "dupes" when the function is called with `'fields' => 'all_with_object_id'`, but the objects will actually be unique due to the `object_id` addition, so they shouldn't be filtered out.
Adds unit tests. All other unit tests pass.
Fixes#11003.
git-svn-id: https://develop.svn.wordpress.org/trunk@28583 602fd350-edb4-49c9-b593-d223f7449a82
Introduces `taxonomy_hierarchy_is_fresh()`, which is only called in `_get_term_hierarchy()`. The taxonomy's `last_changed` value is checked against the value of `wp_cache_get( 'hierarchy_last_changed', $taxonomy )`.
Adds a unit test - `Tests_Term:test_hierachy_invalidation()`.
See [27101], which makes this type of cache invalidation possible.
Fixes#14485.
git-svn-id: https://develop.svn.wordpress.org/trunk@27102 602fd350-edb4-49c9-b593-d223f7449a82
Introduce `get_taxonomy_last_changed()`, `set_taxonomy_last_changed()`, and `post_taxonomy_is_fresh()`.
`post_taxonomy_is_fresh()` is only called in `get_object_term_cache()` - at which point the taxonomy's `last_changed` value is checked against the post's `{$taxonomy}_last_changed` value.
`set_taxonomy_last_changed()` is called whenever directory database queries are made that insert new terms or affect existing terms.
Fixes#22526.

wp-tests-config.php can/should reside in the root of a develop checkout. `phpunit` should be run from the root.
