## Summary
report and fix https://github.com/Comfy-Org/ComfyUI_frontend/issues/3919
- Convert recursive gcd to iterative to avoid stack overflow
- Add epsilon tolerance (1e-10) for floating-point precision issues
This fixes workflow loading hangs when node trying merge values like
0.01 and 0.001, which caused the original recursive gcd to run
indefinitely due to floating-point modulo never reaching exactly zero.
please notice, we need both iterative and epsilon together to fix this
gcd issue
Call Chain
PrimitiveNode.onAfterGraphConfigured
→ #mergeWidgetConfig
→ #isValidConnection
→ mergeIfValid
→ mergeInputSpec
→ mergeNumericInputSpec
→ lcm(step1, step2)
→ gcd(a, b) ← Problem here
Why It Happened
When some nodes connect to multiple nodes, it may merge values using
LCM, which internally calls GCD.
Original recursive implementation:
```
export const gcd = (a: number, b: number): number => {
return b === 0 ? a : gcd(b, a % b)
}
```
Issues:
1. Stack Overflow: Recursive calls with many nodes exhausted the call
stack.
2. Floating-Point Precision: For values like gcd(0.01, 0.001):
` 0.01 % 0.001 = 0.0009999999999999994 // Not exactly 0!`
3. Due to Ifloating-point representation, the modulo never reaches
exactly zero, causing hundreds or thousands of iterations.

## Summary
- Adds `auto-filter-focus` prop to Select component when filtering is
enabled
- When the dropdown opens, the filter input is automatically focused
- This prevents keystrokes from triggering global shortcuts while the
user is trying to filter options
## Root Cause
When a user opens a Select dropdown with a filter and starts typing
without explicitly clicking the search box, the filter input doesn't
have focus. Keystrokes are then captured by global shortcut handlers
(e.g., pressing "R" triggers "refresh nodes") instead of filtering the
options.
## Solution
PrimeVue's Select component has an `auto-filter-focus` prop that
automatically focuses the filter input when the dropdown opens. By
enabling this whenever filtering is enabled (`selectOptions.length >
4`), users can immediately start typing to filter without needing to
click the search box first.
## Test plan
- [ ] Open a Select dropdown with more than 4 options (e.g., Load
Checkpoint's ckpt_name)
- [ ] Verify the filter input is automatically focused when the dropdown
opens
- [ ] Type a character and verify it filters the list instead of
triggering shortcuts
- [ ] Verify no console errors when opening/closing the dropdown

## Summary
This PR improves the user experience by automatically focusing the
search input field when opening the Workflows, Model Library, or Node
Library sidebar tabs.
## Changes
- **SearchBox.vue**: Exposed a `focus()` method to allow parent
components to programmatically set focus on the input.
- **WorkflowsSidebarTab.vue**: Added a watcher to focus the search box
when the tab is activated.
- **ModelLibrarySidebarTab.vue**: Added autofocus on component mount.
- **NodeLibrarySidebarTab.vue**: Added autofocus on component mount.
## Motivation
Users often switch to these tabs specifically to search for an item.
Automatically focusing the search box reduces friction and saves a
click.

## Summary
Fixes Vue Nodes 2.0 dropdowns not displaying the selected model when
created from the Asset Browser.
## Root Cause
Widget values were set AFTER the node was added to the graph, causing
Vue's reactivity system to capture stale initial values.
## Solution
Set widget value BEFORE adding node to graph in
`createModelNodeFromAsset.ts`.
## Changes
- **1 file changed**: `createModelNodeFromAsset.ts`
- **4 lines added, 1 removed**: Move widget value assignment before
graph.add()
This ensures Vue's reactivity system captures the correct initial widget
value when the node is created.

## Summary
- Fix slot link drag and snap/attraction not working on mobile browsers
in Vue Nodes 2.0 mode
- Use `document.elementFromPoint()` to get the actual element under the
pointer instead of relying on `event.target`
## Root Cause
On touch/mobile devices, pointer events have "implicit pointer capture"
- when you touch an element, all subsequent pointer events
(`pointermove`, `pointerup`) for that touch are sent to the same element
where the touch started, regardless of where the pointer moves.
The code was using `event.target` to find slots under the pointer for
snap/attraction. On touch devices, this always returned the original
slot element (where the drag started), not the element currently under
the touch point. This caused:
- No snap/attraction when dragging links over other slots
- Connections failing when dropping on target slots

## After

## Test plan
- [ ] Enable Vue Nodes 2.0 mode in settings
- [ ] Test on mobile browser or Chrome DevTools mobile simulation
- [ ] Drag a link from one node's output slot to another node's input
slot
- [ ] Verify the link snaps/attracts to compatible slots during drag
- [ ] Verify the connection is made successfully on drop
Fixes#7224
## Summary
Model selection dropdowns now automatically refresh after uploading a
new model, ensuring users see newly uploaded models immediately.
## Changes
- **Cache Orchestration**: Upload wizard now refreshes model caches by
coordinating between `modelToNodeStore` and `assetsStore`
- **Smart Refetching**: Only refreshes node types that use the uploaded
model category (e.g., uploading a checkpoint refreshes
`CheckpointLoaderSimple` but not `LoraLoader`)
- **Clean Architecture**: Stores remain decoupled - the upload wizard
composable orchestrates the refresh logic
## Technical Details
After successful upload, `useUploadModelWizard`:
1. Gets all node providers for the model type from `modelToNodeStore`
2. Calls `assetsStore.updateModelsForNodeType()` for each affected node
type
3. Model dropdowns reactively update via Pinia store watchers
## Review Focus
- Orchestration pattern in upload wizard keeps stores decoupled
- Efficient cache invalidation - only refreshes affected node types

When moving an existing link with subgraphInput as source to a new node,
the prior link is removed, but the previous target node would not have
it's link property cleared.
Resolves#7225
Also re-enables several functional skipped tests.
It feels like I'm having to play whack-a-mole reimplementing the same
fixes on every permutation of subgraphIO links. I'd like to setup up a
unified test set that covers them all, but wouldn't want the added work
to further delay this fix.

Previously the color of a link would simply use the type of the target
slot and fallback to the type of the origin slot. When a connection is
made to a node that accepts the any type ('*'), the link has the green
color of an unknown type.
Instead, when a connection is made, the type of a link is now calculated
as the greatest common type of the source and destination. This means
that connections to reroutes are correctly colored.

## Summary
Fixes an issue where Playwright HTML reports were not being generated
for `chromium-2x`, `chromium-0.5x`, and `mobile-chrome` test runs,
causing 404 errors when accessing report links in PR comments.
## Problem
Only the first report link (chromium) had contents - the other three
browsers returned 404 errors. Investigation revealed that artifacts for
non-chromium browsers were only uploading 1 file (report.json) instead
of the full HTML report with ~32 files.
The root cause was that these browsers run very few tests (1-6 tests
each), and when using `--reporter=html --reporter=json` together,
Playwright would only generate the JSON report without the HTML assets.
## Solution
Changed the workflow for non-chromium browsers to use the same approach
as the sharded chromium tests:
1. Run tests with `--reporter=blob`
2. Generate HTML and JSON reports separately using `merge-reports`
This ensures both HTML and JSON reports are always generated with
complete assets, regardless of test count.
## Testing
The fix can be verified by:
1. Checking that this PR's workflow run uploads similar file counts for
all browsers
2. Confirming all 4 report links are accessible and show proper HTML
content

## Summary
Adds step-specific `data-attr` attributes throughout the Upload Model
wizard to enable PostHog analytics tracking and action creation,
following PostHog's recommended best practices for element labeling.
## Changes
- **What**: Added `data-attr` attributes to all key interactive elements
in the Upload Model flow (buttons, inputs, selectors)
- **Step-based naming**: Attributes include step numbers for funnel
analysis (e.g., `upload-model-step1-continue-button`)
- **Coverage**: Entry button, URL input, help link, navigation buttons
(cancel/back/continue/confirm/finish), and model type selector
## Benefits
- Enables creation of stable PostHog actions using CSS selectors like
`[data-attr="upload-model-step2-confirm-button"]`
- Allows funnel analysis to track user progression through the 3-step
upload wizard
- Identifies drop-off points and help-seeking behavior
- Follows PostHog best practice of using data attributes over CSS
classes (especially important with Tailwind)
## Review Focus
- Naming consistency and clarity of data-attr values
- Completeness of coverage across the upload flow

Previously, right-clicking on a Vue node would deselect all other
selected nodes because the pointerup event handler was calling
toggleNodeSelectionAfterPointerUp regardless of which mouse button was
released.
This fix skips selection handling when the right mouse button (button 2)
is released, allowing the context menu to operate on the existing
selection.
## Summary
- Fixes right-click deselecting all selected nodes when using Vue node
rendering
- Now right-clicking preserves the existing selection, allowing context
menu
actions on multiple nodes
## Problem
When multiple nodes were selected and user right-clicked on one of them,
the
`pointerup` event handler would call
`toggleNodeSelectionAfterPointerUp`, which
deselected everything except the clicked node. This broke multi-node
context menu
operations.
## Solution
Skip selection handling in `onPointerup` when `event.button === 2`
(right-click).
The context menu handler manages selection independently

## Summary
- Allow default browser copy (Ctrl+C / Cmd+C) when text is selected
anywhere in the document
- Previously, the graph node copy handler intercepted copy events even
in dialogs
## Problem
Users could not copy error messages from the PromptExecutionError dialog
or other modal dialogs. When pressing Ctrl+C with text selected in a
dialog, the graph copy handler would intercept the event and prevent the
default browser copy behavior.
## Solution
Add a `hasTextSelection()` check to `shouldIgnoreCopyPaste()`. When the
user has any text selected in the document, the function returns `true`,
allowing the default browser copy to proceed.
## Test plan
- [ ] Open an error dialog (trigger a workflow error)
- [ ] Click "Show Report" to expand error details
- [ ] Select some text in the dialog
- [ ] Press Ctrl+C (or Cmd+C on Mac)
- [ ] Paste elsewhere to verify the text was copied
- [ ] Verify graph node copy still works when no text is selected

The output type of a matchType output is initialized to
COMFY_MATCHTYPE_V3, but is updated soon after to the value calculated
from input types. Under some difficult to reproduce circumstances, this
output type may be incorrectly evaluated in connections to other switch
nodes. Since the initial type is never a valid connection, this can
produce errors.
Instead, the output type of a matchtype node is initialized to allow
connections to anything to ensure that the subsequent restriction of
output types is guaranteed to be directional

…s metadata
- Reorder handleFile() to check workflow before parameters
- Add validation to prevent JSON parse errors from crashing imports
- Fix loadGraphData() to use explicit type validation instead of falsy
check
- Ensures ComfyUI-generated PNGs with both metadata types load the
workflow, not parameters
Fixes issue where large workflows (e.g., 634 nodes) were replaced with
basic A1111 format when importing PNG files.
## Summary
Fixed workflow loading from PNG images to prioritize workflow metadata
over parameters, preventing large workflows from being replaced with
basic A1111 format.
## Changes
- **What**: Reordered `handleFile()` to check workflow before
parameters, added JSON parse error handling and validation, fixed
`loadGraphData()` to use explicit type checking instead of falsy check
- **Dependencies**: None
## Review Focus
The key issue was in `handleFile()` where parameters were checked before
workflow, causing ComfyUI-generated PNGs (which contain both workflow
and parameters metadata) to incorrectly import as A1111 format. The fix
ensures:
1. Workflow is always checked first and validated properly
2. Parameters are only used as a fallback when no workflow exists
3. Invalid/malformed workflow data doesn't crash the import process
Additionally, `loadGraphData()` was using a falsy check (`if
(!graphData)`) which could incorrectly replace valid but falsy values.
Now uses explicit type validation.
Tested with real-world PNG containing 634-node workflow (780KB) +
parameters (1KB) - now correctly loads the workflow instead of
discarding it.
