* fix(v3): warm up dialog types in go-json cache to prevent Windows panic
Add FileFilter, OpenFileDialogOptions, SaveFileDialogOptions, and
MessageDialogOptions to the init() warmup to prevent index out of bounds
panic on Windows when these types are first unmarshaled.
Fixes goccy/go-json#474 for Wails internal dialog types.
* fix(v3): revert goccy/go-json to stdlib encoding/json to fix Windows panic
goccy/go-json has a type address calculation bug on Windows that causes
index out of bounds panic when decoding user-defined types for the first time.
This reverts all runtime usages of goccy/go-json back to stdlib encoding/json.
Test and benchmark files are left unchanged.
Partially reverts PR #4843.
* perf(v3): optimize JSON processing and reduce allocations in hot paths
- Switch to goccy/go-json for method binding, events, and HTTP transport
(21-63% faster, 40-60% less memory for method calls)
- Optimize BoundMethod struct layout to reduce padding (144 -> 136 bytes)
- Cache isVariadic flag at registration to avoid reflect call per invocation
- Use stack-allocated buffer for method arguments (<=8 args)
- Optimize result collection to avoid slice allocation for single return values
- Use sync.Map for MIME cache to improve concurrent read performance
- Use buffer pool for HTTP transport request body reading
- Lazily allocate CloseNotify channel in content type sniffer
- Remove debug CSS logging from asset server
- Add comprehensive benchmark tests (build tag: bench)
Performance improvements for BoundMethod.Call:
- SimpleCall: 1290ns -> 930ns (28% faster), 240B -> 80B (67% less memory)
- ComplexCall: 10500ns -> 3900ns (63% faster), 1192B -> 1020B (14% less)
- VariadicCall: 3460ns -> 1600ns (54% faster), 512B -> 289B (44% less)
* perf(v3): add max size limit to buffer pool to prevent memory bloat
Buffers larger than 512KB are not returned to the pool, allowing GC
to reclaim memory after large requests (e.g., base64 encoded images).
* perf(v3): remove mimetype library dependency, saving ~208KB binary size
- Replace github.com/wailsapp/mimetype with expanded extension map + stdlib
- Expand MIME type map from 16 to 50+ common web formats (fonts, audio, video, etc.)
- Add comprehensive test suite validating MIME detection for all web formats
- Use http.DetectContentType as fallback for unknown extensions
- Actual binary size reduction: 1.2MB (11MB -> 9.8MB in test app)
* perf(v3): migrate all runtime code to goccy/go-json
Migrate remaining encoding/json usages to goccy/go-json in:
- pkg/application (android, darwin, ios, single_instance, webview_window)
- pkg/services (kvstore, notifications on all platforms)
- internal/assetserver/webview (request/response handling)
- internal/runtime and internal/capabilities
Note: encoding/json (110KB) remains in binary because:
1. goccy/go-json imports it for interface compatibility (json.Marshaler, etc.)
2. log/slog (stdlib) uses it for JSON output
The performance benefit is in the hot paths which now use the faster library.
* perf(v3): replace gopkg.in/ini.v1 with minimal .desktop file parser
Replace the gopkg.in/ini.v1 dependency with a purpose-built minimal parser
for Linux .desktop files.
The new parser:
- Only extracts the Exec key from [Desktop Entry] section (all we need)
- Follows the Desktop Entry Specification
- Has comprehensive test coverage (40 tests) including:
- All major file managers (Nautilus, Dolphin, Thunar, PCManFM, Caja, Nemo)
- Edge cases (UTF-8, special chars, comments, empty files, etc.)
- Buffer limit handling
Binary size reduction: 45KB (10.22MB -> 10.18MB)
* perf(v3): remove samber/lo from runtime code, saving ~310KB binary size
Replace samber/lo with Go 1.21+ stdlib slices package and minimal internal
helpers in all runtime code paths. This removes 80 transitive dependencies
from the production binary.
Changes:
- Create internal/sliceutil package with Unique and FindMapKey helpers
- Replace lo.Without with slices.DeleteFunc in event handling
- Replace lo.Ternary with inline if/else in Windows code
- Replace lo.Uniq with sliceutil.Unique for feature flags
- Replace lo.FindKey with sliceutil.FindMapKey for method aliases
- Replace lo.Filter with slices.DeleteFunc in event listeners
- Replace lo.Must with inline panic in w32 package
Binary size: 10.18MB -> 9.87MB (~310KB / 3% reduction)
Note: CLI tools still use samber/lo since they don't affect
production binary size. The application_debug.go file also
retains lo usage as it has //go:build !production tag.
* fix: address CodeRabbit review comments
- Use application/x-typescript MIME type (not IANA-registered text/typescript)
- Fix potential panic in mimetype_stdlib_test.go for short MIME strings
- Use cached isVariadic flag in bindings_optimized_bench_test.go
* fix: initialize goccy/go-json decoder early to fix Windows test failure
On Windows, goccy/go-json's type address calculation can fail if the
decoder is first invoked during test execution rather than at init time.
Force early initialization by unmarshaling a []int during package init.

The iOS service stubs were importing a non-existent package
`github.com/wailsapp/wails/v3/pkg/services` and using an incompatible
interface pattern.
This fix rewrites both files to follow the same pattern as other platforms
(Linux, Windows, Darwin):
- Implement the internal platformDock/platformNotifier interfaces
- Provide New() functions returning *DockService/*NotificationService
- Stub all required interface methods

This commit integrates iOS platform support for Wails v3, adapting the
iOS-specific code to work with the new transport layer architecture.
Key changes:
- Add iOS-specific application, webview, and runtime files
- Add iOS event types and processing
- Add iOS examples and templates
- Update messageprocessor to handle iOS requests
- Move badge_ios.go to dock package
Note: The iOS branch was based on an older v3-alpha and required
significant conflict resolution due to the transport layer refactor
(PR #4702). Some iOS-specific code may need further adaptation:
- processIOSMethod needs to be implemented with new RuntimeRequest signature
- iOS event generation in tasks/events/generate.go needs updating

* Refactor Manager API to use singular naming convention
This is a RENAME-ONLY exercise that converts the Wails v3 Manager API from plural to singular naming for better consistency and clarity.
## Changes Applied
### API Transformations:
- `app.Windows.*` → `app.Window.*`
- `app.Events.*` → `app.Event.*`
- `app.ContextMenus.*` → `app.ContextMenu.*`
- `app.KeyBindings.*` → `app.KeyBinding.*`
- `app.Dialogs.*` → `app.Dialog.*`
- `app.Menus.*` → `app.Menu.*`
- `app.Screens.*` → `app.Screen.*`
### Files Updated:
- **Core Application**: 22 files in `v3/pkg/application/`
- **Examples**: 43+ files in `v3/examples/`
- **Documentation**: 13 files in `docs/src/content/docs/`
- **CLI Tests**: 1 file in `v3/internal/commands/`
### Critical Constraints Preserved:
- ✅ Event string constants unchanged (e.g., "windows:WindowShow")
- ✅ Platform event names preserved (events.Windows, events.Mac, etc.)
- ✅ TypeScript API remains compatible
- ✅ All functionality intact
### Verification:
- ✅ All examples build successfully (`task test:examples` passes)
- ✅ Application package compiles without errors
- ✅ Documentation reflects new API patterns
## Benefits
- **Improved Clarity**: Singular names are more intuitive (`app.Window` vs `app.Windows`)
- **Better Consistency**: Aligns with Go naming conventions
- **Enhanced Developer Experience**: Clearer autocomplete and API discovery

* Fix generator testcases and add cross-platform test cleanup
- Update 28 generator testcase files to use singular API (app.Window.New() vs app.Windows.New())
- Add cross-platform cleanup system with Go script to remove test artifacts
- Add test:all task with comprehensive testing and automatic cleanup
- Fix cleanup to target files vs directories correctly (preserves source directories)

* Fix remaining Windows CI failures by updating all plural API usage to singular
Fixed the last remaining instances of old plural Manager API usage:
- tests/window-visibility-test/main.go: Updated all app.Windows -> app.Window and app.Menus -> app.Menu
- internal/templates/_common/main.go.tmpl: Updated app.Windows -> app.Window and app.Events -> app.Event
- pkg/services/badge/badge_windows.go: Updated app.Windows -> app.Window (Windows-specific fix)
These fixes address the Windows CI failures where platform-specific files still used the old API.
The tests didn't catch this locally because Windows-specific files only compile on Windows.
