-"""gitea-merge-queue — conservative serialized merge bot for Gitea.
-
-Gitea 1.22.6 has auto-merge (`pull_auto_merge`) but no GitHub-style merge
-queue. This script provides the missing serialized policy in user space:
-
-1. Pick the oldest open PR carrying QUEUE_LABEL.
-2. Refuse to act unless main is green.
-3. Refuse fork PRs; the queue may only mutate same-repo branches.
-4. If the PR branch does not contain current main, call Gitea's
-   /pulls/{n}/update endpoint and stop. CI must rerun on the updated head.
-5. If the updated PR head has all required contexts green, merge with the
-   non-bypass merge actor token.
-
-The script is intentionally one-PR-per-run. Workflow/cron concurrency should
-serialize invocations so two green PRs cannot merge against the same main.

-# Regression test for molecule-ai-workspace-runtime#61:
-# asyncio.connect_read_pipe / connect_write_pipe fail with
-# ValueError: "Pipe transport is only for pipes, sockets and character devices"
-# when stdout is a regular file (openclaw capture, CI tee, debugging).
-#
-# This workflow reproduces the exact failure mode and verifies the
-# fallback to direct buffer I/O works. It runs on every PR that

+ * Tests for ExternalConnectModal — the modal surfaced after creating a

+ * snippets so the operator can configure their off-host agent.
+ *
+ * Coverage:
+ *   - Renders nothing when info=null
+ *   - Opens dialog when info is provided
+ *   - Default tab: "Universal MCP" when universal_mcp_snippet present, else "Python SDK"
+ *   - Tab switching between all available tabs
+ *   - Snippets show with auth_token replacing placeholders
+ *   - Copy button: calls clipboard API, shows "Copied!", clears after 1.5s
+ *   - Copy failure: shows fallback textarea
+ *   - "I've saved it — close" calls onClose
+ *   - Security warning: one-time token display
+ *   - Fields tab shows raw values
+ *   - Tabs hidden when their snippet is absent
+ *
+ * Fake timers: applied per-describe to avoid mixing with waitFor. Tests that
+ * use waitFor (which needs real timers) run without fake timers. Tests that
+ * verify setTimeout behavior use vi.useFakeTimers() + act(vi.advanceTimersByTime).

- * Unit tests for buildDeployMap — the pure tree-traversal core of

- * What is tested here:
- *   - Root / leaf identification via parent-chain walk
- *   - isDeployingRoot: true when any descendant is "provisioning"
- *   - isActivelyProvisioning: true only for the node itself in that state
- *   - isLockedChild: true for non-root nodes in a deploying tree
- *   - isLockedChild: also true for nodes in deletingIds (even if not deploying)
- *   - descendantProvisioningCount: non-zero only on root nodes
- *   - Performance contract: O(n) single-pass walk — tested by verifying
- *     correctness across 50-node trees (n=50, all cases above)

+ *   - Schedule list rendering (single + multiple)
+ *   - Status dot color (error/ok/idle)
+ *   - Toggle enable/disable via status dot
+ *   - Delete via ConfirmDialog
+ *   - Run Now button triggers POST + POST
+ *   - Create schedule form open/close
+ *   - Edit schedule form pre-fills values
+ *   - Form validation (disabled when cron/prompt empty)
+ *   - Create POST with correct payload
+ *   - Edit PATCH with correct payload
+ *   - Error state surfaces API failures
+ *   - Auto-refresh every 10s (spy)
+ *   - cronToHuman formatting
+ *   - relativeTime formatting

- * - PendingAttachmentPill: name, size, aria-label, onRemove, one-button guard
- * - AttachmentChip: name+glyph, size, no-size, title, onDownload, tone=user/agent, one-button guard
+ * Covers:
+ *   - PendingAttachmentPill renders file name, formatted size, × button
+ *   - PendingAttachmentPill × button has correct aria-label
+ *   - PendingAttachmentPill calls onRemove when × clicked
+ *   - PendingAttachmentPill renders exactly one button
+ *   - AttachmentChip renders attachment name and download glyph
+ *   - AttachmentChip renders size when provided
+ *   - AttachmentChip omits size span when size is undefined
+ *   - AttachmentChip calls onDownload(attachment) on click
+ *   - AttachmentChip title attribute for hover tooltip
+ *   - AttachmentChip tone=user applies blue accent classes
+ *   - AttachmentChip tone=agent applies surface classes
+ *   - AttachmentChip renders exactly one button
 *
- * Pattern: render the real component, inspect actual DOM output.
- * No mocking of the components themselves.
+ * NOTE: No @testing-library/jest-dom import — use textContent / className /
+ * getAttribute checks to avoid "expect is not defined" errors in this vitest
+ * configuration.

core-be	86b2935755	[core-be-agent] fix hub_test.go: unbuffered channel hang + pointer identity Root cause of CI hang (CI / Platform (Go) failing after 2m11s): 1. TestBroadcast_DropsOnClosedChannel: created an UNBUFFERED channel (make(chan []byte) with no buffer). When Broadcast calls safeSend on this channel, the send blocks indefinitely because nothing is reading from it. go test hangs forever waiting for the test to complete. Fix: use make(chan []byte, 1) buffered channel, fill and close it so safeSend hits the default case (returns false) without blocking. 2. Pointer identity: Broadcast tests used anonymous struct literals in h.clients map assignments, but Go map keys store copies of structs. The range iteration returns a pointer to the stored COPY, not the original literal — so the pointers differ. This matters for tests that might assert pointer identity or pass the client to other functions. Fix: use named client variables so the map key and Broadcast's range both refer to the same *Client pointer. Applied to all Broadcast tests defensively.

core-be	7ebdbe102c	[core-be-agent] fix type mismatch: return sqlmock.Sqlmock (interface), not sqlmock.Sqlmock sqlmock.New() returns (Sqlmock, error) where Sqlmock is the interface type, not a pointer. setupTestDB correctly returns sqlmock.Sqlmock (interface), but setupWorkspaceCrudTest and setupInstructionsTestDB incorrectly declared sqlmock.Sqlmock (pointer to interface). In Go, Interface is a distinct type from Interface — this would be a compile error. Root cause: copy-paste from setupWorkspaceCrudTest where the original author assumed sqlmock.Sqlmock was the correct type. Fix: change both setup functions to return sqlmock.Sqlmock (interface) to match what sqlmock.New() actually returns. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>	2026-05-13 09:06:08 +00:00
core-be	446ef9c467	[core-be-agent] fix vet warnings: unused variables in hub_test and bundle_helpers_test Per QA review of PR #794: 1. hub_test.go TestNewHub_WithAccessChecker: `called` was set but never read (unused variable → go vet failure). Added assertion that checks `called` is true after verifying the access checker was invoked. 2. bundle_helpers_test.go TestSplitLines_Empty: `want` was declared as []string{""} but only len(want) was used — the actual content was never compared. Fixed to assert len(got)==1 && got[0]=="", which validates the correct split behavior for an empty string. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>	2026-05-13 09:06:08 +00:00
core-be	2e261e1b91	[core-be-agent] fix tests: routing engine + setupInstructionsTest Two compounding test bugs were causing CI failures in the Platform (Go) job: 1. workspace_crud_test.go: 9 Update tests still registered routes on a separate r2 := gin.New() but called r.ServeHTTP() on the original engine from setupWorkspaceCrudTest. This sent requests to r (which had no PATCH route) → 404 instead of the expected validation error. Fixed: use r consistently for both route registration and serving. 2. instructions_test.go: setupInstructionsTest() called setupTestDB() (which sets global db.DB = mockDB and returns a gin engine with it) then DISCARDED that engine and created a fresh gin.New(). Every test then created ANOTHER fresh gin.New() for route registration. So the route registration and r.ServeHTTP() happened on two completely different gin engines — requests never reached the handler at all. Fixed: introduce setupInstructionsTestDB() that returns the gin engine from setupTestDB, update all tests to use it, and drop the redundant gin.New() calls.

TestUpdate_WorkspaceNotFound same.

core-be	9ce9931f86	[core-be-agent] fix tests: CascadeDelete mock call, instructions r2→r cleanup - workspace_crud_test.go: TestCascadeDelete_DescendantQueryError was setting a mock expectation but never calling CascadeDelete — sqlmock would report "expected query not executed" at test end. Now calls CascadeDelete directly with a minimal handler (nil deps are fine since the error path returns before StopWorkspace/RemoveVolume are reached). - instructions_test.go: All Create/Update tests declared r2:=gin.New() then called r2.ServeHTTP while the setup's r engine sat unused. Unified to use r consistently (the r2 declarations were already renamed to r in the prior edit pass). Also removed dead code in TestInstructionsCreate_HappyPath (r.POST routed to h.List on an unused engine).	2026-05-13 09:06:08 +00:00
