Issue 1753 — Move/Reorder Test Suites: a no-op move/reorder was reported as an error and showed a raw server message

Issue: #1753 Branch: fix/issue-1753 · Fix commit: 13f2ca183 (landed in the #1740 code-review commit) Screen: gui/templates/testcases/suiteMove.html · BFF: api/suitemove/index.php Status: VERIFIED FIXED (2026-10-12) — the issue was a stale report of a fix that had already landed

Symptom

Clicking Move up on the first row, or submitting an unchanged order, answered HTTP 400 {"status":"error","code":"no_change"}. The screen painted it as a red error banner containing the untranslated server string The suite is already at that boundary / The order did not change.

Two problems in one:

1. a no-op is a success, not a failure — every sibling BFF answers it with HTTP 200 {"status":"no_change"} (api/tcreorder, api/tcstepsreorder, api/reqtreereorder);
2. the BFF sent an English message that the screen displayed verbatim, bypassing i18n.

Additionally the reorder branch detected "nothing changed" after change_order_bulk(), i.e. it reported a failure for a request that had already written to the DB.

Root cause chain

The no-op answers lived in three places in api/suitemove/index.php, all reporting failure:

#	Site (pre-fix)	Pre-fix	Fixed code
1	move up/down at a boundary	out(... 'error','code'=>'no_change','message'=>'Suite is already at the boundary', 400)	api/suitemove/index.php:778-781 → out(array('status'=>'no_change','message'=>'Suite is already at the boundary')) (HTTP default 200)
2	move top/bottom already in place	same 400 status:error code:no_change	api/suitemove/index.php:837-843 → out(array('status'=>'no_change','message'=>'The suite is already at that position'))
3	reorder with an unchanged list	the no-op was checked after change_order_bulk()	api/suitemove/index.php:987-991 → if ($newOrder === $currentOrder) runs before the write at :993-994

out($data, $code = null) (api/suitemove/index.php:153-160) only calls http_response_code() when an explicit code is passed; with no second argument the response is HTTP 200. That is why the fixed calls answer 200 while the pre-fix ,400) produced HTTP 400.

The i18n half was on the screen side: gui/templates/testcases/suiteMove.html:392-396 treats no_change as success and substitutes the localized key smv.stNoChangeMsg instead of echoing r.message. The key is present in all 10 locale bundles (en.json:5199 … zh.json:5199).

Why the report was stale

The defect was introduced by the BFF cut a45462e2c (2026-09-30 12:35:24Z; that commit touched only api/suitemove/index.php — the screen suiteMove.html arrived later, in 0674bbdd5). It was fixed by a later #1740 code-review commit, 13f2ca183 ("#1740: apply code-review fixes to Move/Reorder Test Suites"): authored 2026-09-30 13:30:30Z, committed/landed 2026-09-30 13:35:13Z (19 commits after a45462e2c). Issue #1753 was filed at 2026-09-30T13:30:46Z — after the fix was authored but before it was committed — describing the then-current code. git merge-base --is-ancestor 13f2ca183 origin/sebiboga is true, so no build carries the reported behaviour today.

Fix

No new change was required: the three out(...) calls above plus the screen branch already implement the requested contract. This run verified that contract, added the Regression — Issue #1753 suite and this documentation, and closed the tracking issue.

Alternatives considered (and why the chosen contract is right)

Option	Verdict
keep 400 and only localize the message	rejected — the status code is the contract the siblings (tcreorder etc.) already fixed; clients now test status
answer 200 {"status":"ok"} for a no-op	rejected — the screen would print the caller's "moved up" text, which is a lie
check the reorder no-op after change_order_bulk()	rejected — a "failure" for a request that already wrote

Verification

Live, on current origin/sebiboga (6b7f83bf0), fixture FIX1753 Project (FX1753):

curl -s -c /tmp/tl_cookies.txt -X POST http://localhost:8082/login.php \
     -d "tl_login=admin&tl_password=admin&destination=&reqURI=&ssodisable="
B="http://localhost:8082/api/suitemove/index.php"; C='-b /tmp/tl_cookies.txt -H Origin:http://localhost:8082'

curl -s -w '\nHTTP %{http_code}\n' $C -X POST "$B" -d "action=move&tproject_id=1&node_id=2&position=up"
#   HTTP 200 {"status":"no_change","message":"Suite is already at the boundary"}

curl -s -w '\nHTTP %{http_code}\n' $C -X POST "$B" -d "action=reorder&tproject_id=1&container_id=1&nodelist=2,3"
#   HTTP 200 {"status":"no_change","message":"The order did not change"}
#   DB node_order stayed 2->0, 3->1  (no write)

Case	Expected	Observed
move up on first row	200 no_change, no write	200 no_change
move down on last row	200 no_change	200 no_change
reorder current order	200 no_change, DB untouched	200 no_change, DB 2->0,3->1
real move down / up	200 ok, order flips	200 ok, DB flips and restores
screen forced no-op	neutral localized notice	.notice = The order is already like that - nothing to change.
events ERROR/WARNING rows	0 new	0

The screen after a forced no-op — a neutral, localized notice instead of a red error banner:

Suite Regression — Issue #1753 in tmp/TLU_Test_Cases.md: 7 API + 5 screen PASS / 0 FAIL.
