* Fix RSOD when $tw.utils.addClass receives a class string with whitespace
PR #9251 replaced the manual setAttribute("class", ...) implementation of
$tw.utils.addClass/removeClass/toggleClass with direct Element.classList
calls. Unlike setAttribute, classList.add/remove/toggle throws
InvalidCharacterError on any token containing whitespace, so callers that
pass a whole class string (e.g. modal.js passing tiddler.fields.class)
now crash.
Manual repro on tw5-com: open SampleWizard, set the `class` field to
"aaa bbb", Done, open popup -> OK -> open nested popup -> RSOD.
Fix: split the className argument on whitespace in deprecated.js and feed
individual tokens to classList. A small splitClasses() helper keeps the
three functions symmetrical.
Adds adversarial regression tests in test-utils.js covering:
- ASCII whitespace variants (space, tab, CR, LF, mixed runs, padding)
- Unicode whitespace (U+00A0 non-breaking space)
- de-duplication across single and multiple calls
- remove/toggle no-op on missing tokens
- toggle with status undefined / true / false
- silent no-op for whitespace-only / empty / non-string / null input
- silent no-op when the element has no classList
* Move new tests to their own file
* Add backwards-compat regression tests for deprecated.js
Locks in pre-5.4.0 tolerant behaviour of $:/core/modules/utils/
deprecated.js helpers that regressed in PR #9251. Each spec targets an
edge-case input the current one-line modern equivalents reject:
- repeat: negative count / null / undefined str
- startsWith / endsWith: RegExp search arg
- stringifyNumber: null / undefined
- domContains: boolean return, self-check
- hasClass: null element, classless element
- getLocationPath: query preservation, hash stripping
(browser-only; pends in Node because the TW5 sandbox has no `window`)
Also picks up the addClass/removeClass/toggleClass whitespace specs
moved out of test-utils.js by the previous commit, so all deprecated.js
coverage lives together.
Fails 8 specs on current HEAD; the follow-up deprecated.js restoration
commit turns them green.
* Restore pre-5.4.0 behaviour of deprecated.js utilities
PR #9251 replaced several helpers in $:/core/modules/utils/deprecated.js
with one-line ES2017 equivalents that diverge from the originals on
edge-case inputs. Follow-up PRs fixed the most visible cases
(getLocationHash #9622, isDate #9771, addClass empty-string #9561 and
whitespace 005e17537); this commit closes the rest:
- repeat: manual loop tolerates negative count / null / undefined str
- startsWith / endsWith: substring compare tolerates RegExp search arg
- stringifyNumber: `num + ""` coercion tolerates null / undefined
- domContains: `a !== b && a.contains(b)` returns boolean, handles self
- hasClass: null-element guard, strict-false return
- getLocationPath: `toString().split("#")[0]` preserves the query
string in permalinks (startup/story.js:214, 217) -- the most visible
user-facing regression, causing ?lang=de etc. to silently drop.
IE-only fallbacks in Math.sign, strEndsWith, domContains, and
domMatchesSelector are removed; TW5 no longer supports IE.
Covered by the regression specs added in the previous commit.
