fix(types): widen ToolProviderApiEntity icon to include EmojiIconDict by xr843 · Pull Request #34560 · langgenius/dify

xr843 · 2026-04-05T07:04:41Z

Summary

Follow-up to #34380 per @asukaminato0721's suggestion that the remaining pyrefly type errors "can fix it in another pr."

Pyrefly flags two type errors at services/tools/tools_transform_service.py:88/92:

ERROR `str | EmojiIconDict` is not assignable to attribute `icon` with type `Mapping[str, str] | str` [bad-assignment]
  --> services/tools/tools_transform_service.py:88:33
ERROR `str | EmojiIconDict` is not assignable to attribute `icon_dark` with type `Mapping[str, str] | str` [bad-assignment]
  --> services/tools/tools_transform_service.py:92:42

EmojiIconDict is a TypedDict with specific keys (background, content), which pyrefly does not structurally treat as Mapping[str, str].

Changes

Move EmojiIconDict from api/core/tools/tool_manager.py to api/core/tools/entities/common_entities.py so it can be imported by api_entities.py without a circular import
Widen ToolProviderApiEntity.icon and .icon_dark type annotations to accept EmojiIconDict
Update tool_manager.py to re-import EmojiIconDict from the new location

No runtime behavior change — purely a type annotation fix.

Test plan

AST syntax check on all three modified files
CI type checks (pyrefly) should show the two errors resolved
Existing tests continue to pass

Fixed the remaining type error in pyrefly diff. Narrowed the return type of get_tool_provider_icon_url to str | Mapping[str, str] (removing EmojiIconDict from return type since it's structurally a Mapping[str, str]), and used cast() for branches returning the raw icon parameter. This should eliminate the pyrefly diff showing the EmojiIconDict has no attribute startswith error change.

Hi @asukaminato0721, all type errors have been resolved — the latest Pyrefly diff shows "No changes detected" and all CI checks are green now. Could you re-review when you get a chance? Thanks!

resolve conflict

…onDict Pyrefly flags type incompatibility at services/tools/tools_transform_service.py:88/92 where get_tool_provider_icon_url returns str | EmojiIconDict but ToolProviderApiEntity.icon/icon_dark only accept str | Mapping[str, str]. EmojiIconDict is a TypedDict with specific keys (background, content) which pyrefly does not structurally treat as Mapping[str, str]. Move EmojiIconDict from tool_manager.py to common_entities.py so it can be reused by api_entities.py without introducing a circular import, then widen the icon/icon_dark fields to accept EmojiIconDict. Follow-up to langgenius#34380 (per reviewer suggestion). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

type-check-core fails after widening ToolProviderApiEntity.icon: 4 errors in node_runtime.resolve_provider_icons assignments and tools_transform_service.get_tool_provider_icon_url calls. Widen the receiving types to match.

…t is already Mapping[str, str] EmojiIconDict extends TypedDict which is a subtype of Mapping[str, str], so adding it explicitly to union types is redundant and causes: - Pyrefly bad-override error (resolve_provider_icons vs protocol) - Pyrefly missing-attribute error (EmojiIconDict has no startswith) Revert to original Mapping[str, str] signatures — EmojiIconDict values pass through naturally without explicit mention.

…ignments - Restore EmojiIconDict in get_tool_provider_icon_url signature (fixes basedpyright bad-argument-type at call sites) - Cast builtin_tool.icon/icon_dark to narrow type at assignment in resolve_provider_icons (EmojiIconDict is a TypedDict with str values, compatible with Mapping[str, str] but type checkers need the cast) - Keep resolve_provider_icons return type unchanged (matches protocol)

@asukaminato0721 Gentle ping — CI is all green, and the Pyrefly diff only shows pre-existing errors from the base branch (not introduced by this PR).

The type change from Mapping to EmojiIconDict is exactly what this PR intends — making the type more precise. Could you take another look when you have a moment? Thanks!

xr843 · 2026-04-27T13:43:58Z

Friendly follow-up @asukaminato0721 — it's been a couple of weeks. To recap the state: CI is fully green, the Pyrefly diff shows only pre-existing errors from the base branch (none introduced by this PR), and the change is the minimal, intentional one — narrowing ToolProviderApiEntity.icon from Mapping to the more precise EmojiIconDict union it actually accepts.\n\nIf there's a remaining concern I missed, happy to address it. Otherwise would you mind dismissing the stale review so this small typing fix can land? Thanks for your time.
