- Define STK_PATH_SEP macro to handle Windows and Unix path separators.
- Refactor extract_module_id to use STK_PATH_SEP.
- Simplify stk_module_load by delegating module ID extraction to extract_module_id.
Implement complete hot-reload logic in stk_poll() supporting reload,
load, and unload operations. Module arrays dynamically grow/shrink
with automatic defragmentation to maintain tight memory layout.
- Grow arrays when loads exceed unloads
- Fill holes left by unloads with new modules
- Defragment and trim arrays when unloads exceed loads
- Unload before realloc to minimize peak memory usage
- Replace sprintf with safe C89 build_path() helper
Replace the placeholder TODO logs in the polling loop with logic to
resolve filesystem events into specific module indices.
- Centralizing State: Refactored is_module_loaded to is_mod_loaded to
check against the global stk_module_ids array, removing the need to
pass local buffers and preparing for unified lifetime management.
- Standardizing Identity: Updated extract_module_id to use a
consistent output buffer.
- Categorized Event Processing: Implemented a two-pass approach in
stk_poll to count event types (LOAD, UNLOAD, RELOAD) and allocate
tracking arrays, replacing the previous stubbed switch statement.
- Mapping Events to Indices: The poll loop now resolves filenames
back to their specific loaded indices via is_mod_loaded to
identify exactly which mod_id and index require action.
- Improved Flow Control: Introduced a finish_stk_poll label to
ensure consistent cleanup and return values when no events are
detected or processing is complete.
* Introduced stk_initialized flag.
* Updated all configuration setters (stk_set_mod_dir, stk_set_tmp_dir_name, stk_set_module_init_fn, and stk_set_module_shutdown_fn) to silently return if the library is already initialized.
* Ensures internal state consistency by locking paths and function entry points once stk_init has been called.
* Added functions to set mod dir, temp dir name, and module init/shutdown function names.
* Replaced hardcoded string literals with configurable static buffers in module.c.
* Improved string safety by replacing sprintf with strncpy/strncat.
* Updated stk_init local path buffers to handle maximum combined path lengths.
- Change %zu to %lu in stk_init to support older msvcrt.dll (Windows 7/XP)
- Update pluralization logic to correctly handle "0 mods" vs "1 mod"
- Add temporary stk_log calls to stk_poll for monitoring module events
Add foundation for cross-platform hot-reload system by isolating
loaded modules from source files using a temporary directory.
Changes:
- Add configurable tmp directory parameter to stk_init()
(defaults to mods/.tmp/ if not specified)
- Copy all modules from mods/ to .tmp/ on initialization
- Load modules exclusively from .tmp/ directory
- Clean up .tmp/ directory on shutdown
- Add cross-platform file operations:
* platform_mkdir() - create directories
* platform_copy_file() - copy files
* platform_remove_file() - delete files
* platform_remove_dir() - delete directory and contents
- Improve BSD kqueue implementation to detect file overwrites
(adds individual file watches with NOTE_WRITE)
This isolates the loaded shared libraries from source files,
preventing segfaults when users overwrite mods using cp/copy
operations. The actual reload logic remains unimplemented
(marked as TODO in stk_poll switch cases).
- Use fixed STK_PATH_MAX and STK_MOD_ID_BUFFER throughout for predictable memory
- Filter by platform-specific extensions (.so/.dll/.dylib) with compile-time length
- Add RELOAD event detection and is_module_loaded() helper
- Maintain feature parity across all platforms
