v4.3.0

Restructured compileGlob() into three distinct phases:
1. Resolve glob patterns and clean ALL output directories upfront
2. Compile all TypeScript tasks (no filesystem cleanup during this phase)
3. Unpack all outputs after all compilations complete

This prevents XFS metadata corruption from rm operations overlapping
with TypeScript compilation writes to sibling directories.

+- Export logger from ts/mod_logger/index.ts and re-export from ts/index.ts
+- Replace console.log/console.error/console.warn calls in mod_cli, mod_compiler, and mod_unpack with TsBuildLogger methods for consistent, hierarchical output
+- Refactor error-summary, emit and type-check output to use logger separators, colors, and structured messages
+
+## 2026-03-05 - 4.2.6 - fix(meta)
+no changes
+
+- Current package version: 4.2.5
+- No code or file changes detected in this commit; no release required
+
+## 2026-03-05 - 4.2.5 - fix(compiler)
+yield to the event loop after TypeScript emit to allow pending microtasks and I/O to settle before reading or modifying the output directory
+
+- Added await new Promise(resolve => process.nextTick(resolve)) immediately after program.emit()
+- Prevents race conditions by allowing libuv write completions and other deferred callbacks to complete before accessing the output directory
+- File changed: ts/mod_compiler/classes.tscompiler.ts
+
+## 2026-03-05 - 4.2.4 - fix(fshelpers)
+remove outdated comment about using synchronous rm to avoid XFS metadata corruption
+
+- Comment-only change in ts/mod_fs/classes.fshelpers.ts; no runtime or API behavior changes
+- Bump patch version from 4.2.3 to 4.2.4
+
+## 2026-03-05 - 4.2.3 - fix(compiler)
+defer unpacking until after all compilations and remove diagnostic filesystem syncs to avoid XFS metadata visibility issues
+
+- Queue pending unpack operations during compilation and run them after all compile tasks complete to avoid modifying output directories while other compilations are writing.
+- Remove TypeScript sys interception, execSync('sync') calls, and per-unpack fs.fsyncSync usage that attempted to work around XFS delayed metadata commits; rely on performing all unpacks after compilation instead.
+- Clean up noisy diagnostic code (external 'ls' comparisons, readdir snapshots) and simplify logging of unpack results.
+- Remove unused imports (fs and child_process.execSync) from the compiler module.
+
+## 2026-03-05 - 4.2.2 - fix(compiler)
+force global filesystem sync to flush XFS delayed logging and add diagnostics comparing Node's readdirSync with system ls to detect directory entry inconsistencies
+
+- Replace per-directory fs.fsyncSync loop with execSync('sync') to ensure parent B+tree metadata is flushed on XFS
+- Import execSync from child_process
+- Add diagnostic comparison: run ls -1 and compare its entries to fs.readdirSync; log mismatches and full entry lists for debugging Node.js caching/readdir inconsistencies
+
+## 2026-03-05 - 4.2.1 - fix(compiler)
+use TypeScript sys hooks instead of fs monkeypatching to detect writes/deletes in previous output directories
+
+- Replace direct fs.* monkeypatching with interception of typescript.sys.writeFile, typescript.sys.deleteFile and typescript.sys.createDirectory
+- Add guards for optional sys.deleteFile before overriding it and preserve original sys methods to restore after compilation
+- Update diagnostic messages to reference TypeScript sys ops and add an informational message when no ops are observed
+- Reduce surface area of changes by avoiding global fs changes and focusing on TypeScript's sys API for safer interception
+
+## 2026-03-05 - 4.2.0 - feat(mod_compiler)
+add diagnostic interception of fs operations to detect and report unexpected file system changes in previously compiled output directories during compilation
+
+- Wraps fs.unlinkSync, fs.rmSync, fs.rmdirSync, fs.renameSync and fs.writeFileSync to record operations targeting other successful output directories during a compile.
+- Enabled only when there are previously compiled output dirs and when not running in quiet or JSON mode; original fs methods are restored after compilation.
+- Logs up to 30 intercepted operations and prints a summary count if any ops were observed; intercepted calls still perform the original fs action (diagnostic-only).
+- No functional change to compilation behavior beyond additional diagnostic reporting.
+
+## 2026-03-05 - 4.1.26 - fix(compiler)
+fsync output directories after unpack to avoid XFS delayed logging causing corrupt or invisible directory entries during subsequent TypeScript emits
+
+- Force fsync on each successful output directory (open, fsync, close) before the next compilation step.
+- Prevents XFS delayed logging from making directory entries invisible or corrupted during TypeScript emit operations.
+- Operation swallows errors if a directory doesn't exist yet; non-breaking fix with small additional IO.
+
+## 2026-03-05 - 4.1.25 - fix(mod_unpack)
+flush directory metadata on XFS before reading and use readdirSync-based iteration to avoid missing entries when unpacking
+
+- Call fs.fsyncSync on destination and nested directory file descriptors to force XFS to commit delayed directory metadata (addresses XFS CIL delayed logging causing incomplete readdir/opendir results).
+- Replace opendirSync/readSync loops with readdirSync-based iteration for simpler, deterministic directory listing.
+- Remove unused moved counter and update diagnostic log to report nestedEntries.length for moved entry count.
+
+## 2026-03-05 - 4.1.24 - fix(mod_unpack)
+iterate directories with opendirSync/readSync to avoid missing entries on XFS and ensure directory handles are closed
+
+- Replaced readdirSync loops with opendirSync + readSync for destination and nested directories to provide a single stable directory handle during iteration
+- Added explicit closeSync() calls to close directory handles and avoid resource leaks
+- Avoids partial results/missed entries that can occur when repeatedly calling readdirSync (observed on XFS with delayed metadata)
+- Preserves existing renameSync move logic and increments moved counter while cleaning up the now-empty nested directory
+
+## 2026-03-05 - 4.1.23 - fix(mod_unpack)
+handle partial readdirSync results when moving nested directory entries and add diagnostic log
+
+- Loop over readdirSync results until the nested directory is empty to avoid missing entries from partial reads
+- Count moved entries and print a diagnostic message with the final destination entry count
+- Keep removal of the now-empty nested directory (fs.rmdirSync) after moving contents
+
+## 2026-03-05 - 4.1.22 - fix(mod_compiler)
+improve logging of successful output directories to include a sorted list of entries and use a shortened relative path
+
+- Adds shortDir variable to display relative path instead of repeating inline replace(this.cwd + '/')
+- Appends a sorted, comma-separated list of directory entries to the log output for easier inspection
+- Change located in ts/mod_compiler/classes.tscompiler.ts
+
+## 2026-03-05 - 4.1.21 - fix(compiler)
+log emitted files written outside expected destination directory for diagnostics
+
+- Adds diagnostic logging for emitted files that are not under the configured destDir, listing up to 20 example paths and reporting the remaining count.
+- Logging is conditional: only when not in quiet mode and not emitting JSON.
+- Diagnostic runs after compilation (post-compile) and before unpacking of outputs; paths are trimmed using the process cwd for readability.
+
+## 2026-03-05 - 4.1.20 - fix(mod_compiler)
+add diagnostic snapshots for output directories around clear and compile steps
+
+- Introduce diagSnap helper to log entry and directory counts for successful output directories when not in quiet or JSON mode
+- Call diagSnap before clearing the destination directory, after clearing, and after compilation to aid debugging of missing or unexpected outputs
+- Behavior for emitted files and unpacking is unchanged; this is observational/logging-only instrumentation
+
+## 2026-03-05 - 4.1.19 - fix(mod_fs)
+use synchronous rm to avoid XFS metadata corruption when removing directories
+
+- Replaced async fs.promises.rm with synchronous fs.rmSync in removeDirectory to avoid observed XFS metadata corruption affecting sibling entries under libuv thread-pool and signal pressure
+- Retains previous options: recursive, force, maxRetries, retryDelay
+- Adds inline comment documenting the rationale for using a synchronous removal
+
+## 2026-03-05 - 4.1.18 - fix(mod_compiler)
+add diagnostic logging of output directory states after compilation and after import-path rewriting to aid debugging
+
+- Imported fs to allow reading output directories for diagnostics
+- Logs entries and directory counts for each successful output directory both pre- and post-import-path-rewrite
+- Diagnostics are gated by !isQuiet && !isJson and are read-only (no behavior change)
+- Tags used: 'diag' (post-compilation) and 'diag-post-rewrite' (after rewriting) to help identify missing or unexpected output folders
+
+## 2026-03-05 - 4.1.17 - fix(tsunpacker)
+use synchronous fs operations in tsunpacker to avoid readdir race conditions
+
+- Replaced async fs.promises.readdir/rename/rm/rmdir loops with fs.readdirSync/renameSync/rmSync/rmdirSync
+- Removed readdir retry loops that attempted to handle partial/stale readdir results
+- Updated comment to document rationale: avoid race conditions under signal pressure and XFS metadata lag
+- Note: function remains async but now performs blocking sync filesystem calls which may block the event loop during unpack
+
+## 2026-03-05 - 4.1.16 - fix(mod_unpack)
+handle partial readdir results from signal-interrupted getdents64 when unpacking to ensure sibling removal and nested moves complete
+
+- Loop readdir calls for destination directory until only the source folder remains to avoid partial-listing leftovers
+- Loop readdir calls for nested directory and repeatedly rename entries until the nested directory is empty
+- Prevents leftover files and incomplete moves when readdir returns partial results under signals
+
+## 2026-03-05 - 4.1.15 - fix(mod_unpack)
+flatten nested output directory without temporary rename steps to avoid race conditions
+
+- Replace rename-rm-rename strategy with: remove sibling entries in destination, move nested source entries up into the destination, then remove the now-empty nested folder.
+- Avoid creating temporary sibling directories and avoid removing the destination directory to reduce filesystem race conditions and metadata lag issues (XFS/NFS/etc.).
+- Remove removed removeEmptyDirectory helper and stop using FsHelpers.move/removeDirectory in unpack; import and use fs.promises methods (readdir, rm, rename, rmdir) directly.
+
+## 2026-03-05 - 4.1.14 - fix(fs)
+replace execSync and fsync workarounds with atomic async FsHelpers operations to avoid XFS races and shell dependencies
+
+- Removed child_process.execSync usage and shell mv/rm commands in mod_unpack and mod_compiler.
+- Removed syncDirectoryTree and fsync-based workaround from the compiler module.
+- Use FsHelpers.move and FsHelpers.removeDirectory (async rename/remove) for atomic filesystem operations during unpack.
+- Await performUnpack directly and simplify unpack flow to improve portability and reliability on XFS and other filesystems.
+
+## 2026-03-05 - 4.1.13 - fix(mod_unpack)
+Use child_process.execSync (mv/rm) to perform unpack atomically, replacing async fs operations and logs to avoid ENOENT/partial directory listings on XFS
+
+- Replaced async fs.promises.rename/rm and readdir/stat debugging with execSync rm -rf and mv operations for sequential, atomic moves
+- Imported execSync from child_process and removed verbose console logging and extra fs checks
+- Addresses race conditions observed on filesystems like XFS where libuv async operations can return partial results or ENOENT errors
+
+## 2026-03-05 - 4.1.12 - fix(mod_compiler)
+replace runtime require calls with top-level imports and use execSync/path.join for filesystem sync and traversal
+
+- Added top-level imports: path and execSync from child_process
+- Replaced require('child_process').execSync('sync') with execSync('sync') to force fs sync
+- Replaced require('path').join(...) with path.join(...) when recursing directories
+- Refactor is purely local/maintenance-focused (consistency and slight performance/readability improvement); no functional change expected
+
+## 2026-03-05 - 4.1.11 - fix(mod_compiler)
+flush directory entries before unpack to avoid XFS delayed-log causing partial readdir results
+
+- Add fs import and call child_process.execSync('sync') before unpacking compiled output to force kernel-level sync
+- Add syncDirectoryTree(dir) to recursively open and fsync directory file descriptors and traverse subdirectories
+- Call syncDirectoryTree on the destination directory before performing unpack to ensure TypeScript writeFileSync entries are committed (prevents partial readdir results on XFS)
+- Errors during directory sync are ignored to avoid breaking normal flow
+
+## 2026-03-05 - 4.1.10 - fix(unpack)
+use atomic renames to flatten nested output and make unpacking more reliable
+
+- Replace per-entry moves with an atomic 3-step strategy: rename nested dir to a temp location, remove the destination dir, then rename temp back to the destination to avoid partial readdir/move under signal pressure.
+- FsHelpers.move switched from sync rename to fs.promises.rename to work with async flows.
+- Use fs.promises.rm with retries and explicit temp-dir cleanup to handle previous failed runs.
+- Add diagnostic logging and verification of intermediate states.
+- Removed the older removeSiblingDirectories and moveNestedContentsUp methods in favor of the new rename-based approach.
+
+## 2026-03-05 - 4.1.9 - fix(fs)
+improve filesystem helpers: use sync rename for reliability on certain filesystems; retry rmdir with delays and avoid recursive rm; bump @push.rocks/smartfs to ^1.3.2
+
+- move(): use fs.renameSync to improve reliability on XFS/mounted filesystems where async rename can be interrupted by process managers
+- removeEmptyDirectory(): retry fs.promises.rmdir up to 5 attempts with incremental delays; return on ENOENT; avoid recursive rm on ENOTEMPTY to prevent removing still-valid references
+- Dependency bump: @push.rocks/smartfs from ^1.3.1 to ^1.3.2
+
+## 2026-03-05 - 4.1.8 - fix(unpack)
+catch unpack errors and add verbose unpack logging
+
+- Wrap performUnpack call in the compiler to catch and log exceptions so unpack failures don't crash the process
+- Log the number of directories and files being unpacked when moving nested contents to aid debugging
+
+## 2026-03-05 - 4.1.7 - fix(fs/compiler/unpack)
+robustify directory removal and remove noisy diagnostic logging
+
+- Use fs.promises.rm with force, maxRetries and retryDelay in removeDirectory to reduce intermittent failures during removals.
+- Handle ENOTEMPTY in removeEmptyDirectory by falling back to a recursive rm and ignore ENOENT to avoid errors from transient filesystem metadata lag.
+- Remove several diagnostic/verbose console logs in the compiler and unpacker paths to reduce noisy output and simplify flow.
+- Short-circuit unpack logic when no nesting is detected to avoid unnecessary work and logs.
+- No public API or behavior-breaking changes; suitable for a patch release.
+
+## 2026-03-05 - 4.1.6 - fix(mod_compiler)
+add diagnostic logging to report dist_ts and output directory contents after each compilation task and after import-path rewriting
+
+- Adds DIAG-CROSSTASK logs to inspect dist_ts subdirectories after each task when not in quiet or JSON mode
+- Adds DIAG-FINAL logs to report directory names and file counts for each successful output dir after import-path rewriting
+- Diagnostics use dynamic fs import and are non-intrusive: gated by isQuiet/isJson and errors are ignored
+
+## 2026-03-05 - 4.1.5 - fix(diagnostics)
+add diagnostic logging around compilation and unpack to aid troubleshooting
+
+- Enable TypeScript CompilerOptions.listEmittedFiles to surface emitted file info
+- Log destination directory contents and emitted file/error counts after compile and after unpack (only when not quiet and not json)
+- Add unpack-specific diagnostic logs: shouldUnpack skip, detectNesting result and nestedPath, and nested/destination directory listings before removing sibling directories
+- All logs use console.log and are wrapped in try/catch to avoid throwing; changes are informational and non-breaking
+
+## 2026-03-05 - 4.1.4 - fix(deps)
+bump @git.zone/tspublish dependency to ^1.11.2
+
+- Updated @git.zone/tspublish from ^1.11.0 to ^1.11.2 in package.json
+
+## 2026-03-04 - 4.1.3 - fix(deps)
+bump dependencies: @push.rocks/smartcli, @push.rocks/smartlog, @git.zone/tstest, and @types/node to their newer versions
+
+- @push.rocks/smartcli: ^4.0.19 -> ^4.0.20
+- @push.rocks/smartlog: ^3.1.10 -> ^3.2.1
+- @git.zone/tstest: ^3.1.4 -> ^3.2.0
+- @types/node: ^25.0.3 -> ^25.3.3
+- Non-breaking dependency version bumps
+
+## 2026-01-04 - 4.1.0 - feat(docs)
+update README with improved docs and monorepo/tspublish guidance; namespace and extend npmextra.json with release registries; bump several dependencies
+
+- Bumped dependencies: @git.zone/tspublish ^1.10.3 → ^1.11.0, @push.rocks/smartfs ^1.2.0 → ^1.3.1, @git.zone/tstest ^3.1.3 → ^3.1.4, @types/node ^25.0.1 → ^25.0.3
+- npmextra.json reorganized: replaced legacy keys with namespaced entries (@git.zone/cli, @git.zone/tsdoc) and added @ship.zone/szci; added release configuration with registries [https://verdaccio.lossless.digital, https://registry.npmjs.org] and public accessLevel
+- README rewritten: improved formatting, added emojis and tables, new 'Issue Reporting and Security' section, monorepo/tspublish usage docs, auto-unpack and decorator guidance, CI/CD and troubleshooting improvements
+- Non-breaking changes; recommended next semantic version bump is minor
+
 ## 2025-12-14 - 4.0.2 - fix(TsCompiler)
 Clear output directories before compilation to ensure clean builds and avoid stale files

+### Monorepo Support with tspublish 📦
+
+tsbuild is designed to work seamlessly with [@git.zone/tspublish](https://code.foss.global/git.zone/tspublish) for monorepo workflows. This enables building and publishing multiple packages from a single repository.
+
+#### Directory Structure
+
+```
+my-project/
+├── ts/                    # Main package source
+├── ts_interfaces/         # Shared interfaces (order: 1)
+├── ts_shared/             # Shared utilities (order: 2)
+├── ts_core/               # Core logic (order: 3)
+├── ts_web/                # Web-specific code (order: 4)
+└── ts_node/               # Node-specific code (order: 5)
+```
+
+Each `ts_*` folder can contain its own `tspublish.json` to configure compilation and publishing behavior.
+
+#### tspublish.json Configuration
+
+Create a `tspublish.json` in each `ts_*` folder:
+
+```json
+{
+  "name": "@myorg/core",
+  "order": 3,
+  "unpack": true,
+  "dependencies": ["ts_interfaces", "ts_shared"]
+}
+```
+
+| Option | Type | Default | Description |
+|--------|------|---------|-------------|
+| `name` | string | — | Package name for publishing |
+| `order` | number | `Infinity` | Build sequence (lower builds first) |
+| `unpack` | boolean | `true` | Flatten nested output directories |
+| `dependencies` | string[] | — | Monorepo dependencies to bundle |
+
+#### Build Order
+
+The `tsfolders` command respects the `order` property:
+
+```bash
+npx tsbuild tsfolders
+```
+
+**Default ordering (without tspublish.json):**
+1. `ts_interfaces` - always first (shared types)
+2. `ts_shared` - always second (shared utilities)
+3. Other folders sorted by `order` property
+4. Folders without `order` are built last
+
+**Example output:**
+```
+TypeScript Folder Compilation Plan (5 folders)
+  1/5 ts_interfaces  (order: 1)
+  2/5 ts_shared      (order: 2)
+  3/5 ts_core        (order: 3)
+  4/5 ts_web         (order: 4)
+  5/5 ts_node        (order: 5)
+```
+
+### Auto-Unpack 📁
 
 When TypeScript compiles files that import from sibling directories, it creates nested output:
 
 ```
 dist_ts_core/
-  ts_core/        <- nested output
-  ts_shared/      <- pulled-in dependency
+  ts_core/        ← nested output
+  ts_shared/      ← pulled-in dependency
 ```
 
 tsbuild automatically flattens this to:
 
 ```
 dist_ts_core/
-  index.js        <- flat
+  index.js        ← flat, clean structure
 ```
 
-Configure via `tspublish.json` in source folder:
+This is especially important for monorepos where packages import from each other.
+
+**Control via tspublish.json:**
 ```json
 {
   "unpack": true
 }
 ```
 
-Set `"unpack": false` to disable.
+- `"unpack": true` (default) - Flatten nested directories after compilation
+- `"unpack": false` - Keep original nested structure
 
-### Decorator Support
+**What gets unpacked:**
+- The source folder's contents (`ts_core/`) are moved to the root of `dist_ts_core/`
+- Sibling folders (`ts_shared/`) that were pulled in are removed (they have their own dist)
 
-First-class decorator support out of the box:
+### Decorator Support 🎨
+
+tsbuild supports both **TC39 standard decorators** (recommended) and legacy experimental decorators.
+
+**TC39 Standard Decorators (Preferred)** 🌟
+
+We strongly recommend using TC39 standard decorators for all new code. They are the official JavaScript standard and provide better semantics:
+
+```typescript
+// TC39 standard decorator
+function log(target: any, context: ClassMethodDecoratorContext) {
+  return function (...args: any[]) {
+    console.log(`Calling ${String(context.name)}`);
+    return target.apply(this, args);
+  };
+}
+
+class UserService {
+  @log
+  getUser(id: string) {
+    return { id, name: 'John' };
+  }
+}
+```
+
+**Legacy Decorators (Backwards Compatibility)**
+
+For existing projects using frameworks like NestJS, TypeORM, or Angular that still require experimental decorators:
 
 ```typescript
 @Injectable()
@@ -524,9 +630,19 @@ class UserService {
 }
 ```
 
-Works with NestJS, TypeORM, Inversify, Angular, and other DI frameworks.
+Enable legacy decorators in your `tsconfig.json`:
+```json
+{
+  "compilerOptions": {
+    "experimentalDecorators": true,
+    "emitDecoratorMetadata": true
+  }
+}
+```
