From ae75320ec457e5336bac32ee24d582a87de80faa Mon Sep 17 00:00:00 2001 From: branchseer Date: Sat, 31 Jan 2026 20:56:38 +0800 Subject: [PATCH 01/28] refactor: rename fspy_test_utils to subprocess_test and command_executing to command_for_fn Renamed the crate to use no prefix since it's shared by both fspy and vite_* crates. The macro name now more clearly conveys that it creates a command for executing a function.

Implemented conversions: - From for std::process::Command - From for fspy::Command (under fspy feature flag) Updated all usage sites: - fspy_shared tests: convert Command before calling .status()/.output() - fspy test utils: renamed spawn_std -> spawn_command, accepts Command directly - Renamed track_child! macro -> track_fn! for clarity Fixed circular dependency by moving subprocess_test to dev-dependencies in fspy.

+0800 Subject: [PATCH 06/28] fix: add ctor as dev-dependency for command_for_fn macro users The command_for_fn macro uses the ctor attribute which requires the ctor crate to be available in the calling crate's dependency graph. This is a limitation of Rust's proc-macro system - attribute macros cannot be re-exported through module paths. Added ctor as dev-dependency to vite_pty and updated README to document this requirement for users of the command_for_fn macro.

On Windows, the vt100 parser with Vt100Callbacks (which can write responses back to the PTY) needs to process data as it arrives. Delaying this processing caused the reader to block indefinitely. Now read_until processes each chunk through the parser immediately after reading, just like read_to_end, while still maintaining the buffer for pattern matching and keeping unprocessed remainder for subsequent calls. All tests now pass on both macOS and Windows.

Call read_until() to search in the buffered data 3. Since EOF was reached, no more data can be read, but searches in existing buffer still work Added test: read_until_after_read_to_end - Verifies buffer is preserved after read_to_end - Verifies read_until can search in buffered data - Verifies EOF prevents reading more data All 8 tests pass on both macOS and Windows.

This ensures: 1. Data is processed immediately (critical for Windows PTY) 2. Data is processed exactly once (no double-processing) 3. Buffer accumulates all data for pattern searching 4. When pattern found, consume() processes and removes consumed portion This clean separation makes the code more maintainable while preserving Windows compatibility and buffer search functionality. All 8 tests pass on both macOS and Windows.

The method sends ASCII 0x03 which is interpreted by both Unix PTYs (converted to SIGINT) and Windows ConPTY (generates CTRL_C_EVENT). Includes comprehensive cross-platform test following the pattern from resize_terminal - both Unix and Windows execute the test without skipping, with platform-specific verification code using #[cfg] attributes. Tests pass on both macOS (local) and Windows (aarch64-pc-windows-msvc via cargo xtest cross-compilation).
