feat: implement Klipper repository migration to RatOS fork #92
Conversation
|
""" WalkthroughA new Bash script was introduced to automate migrating the Klipper firmware repository from the official source to the RatOS fork. The update manager configuration was revised to reference a new commit hash. The main update script now calls the migration script if the Klipper repository still tracks the official source. Documentation and mock log generators were updated to include new error codes related to the migration process. The CI workflow was enhanced to include a Bash syntax check step for all shell scripts. The main CLI script's shebang was changed to use environment lookup for Bash. Changes

12-17: Centralize constants for clarity
The constants block is clear. For easier maintenance, consider grouping related Git settings in an array or adding inline comments on each to document their role.

122-150: Implement fetch with retries
Robust exponential backoff logic. You may extract this retry pattern into a helper function if other scripts need similar behavior.
152-186: Handle branch checkout and detached HEAD
Covers detached HEAD scenarios and both local-existing and remote branch creation. Consider optionally cleaning up the temporary branch after a successful migration to avoid clutter.

22-57: Enhance remote URL pattern matching.Currently, only exact HTTPS and one SSH URL are recognized. Consider using a regex or parsing host/path components to support variations (e.g.,
ssh://[email protected]/Klipper3d/klipper.git). This will make the check more robust against different clone formats.Also, guard against an unset
KLIPPER_DIRbefore directory checks.
122-149: Improve fetch retry strategy with exponential backoff.The fixed 5-second retry delay could be replaced with an exponential backoff (e.g., 2^n seconds plus jitter) to reduce server load under repeated failures and improve likelihood of success.
218-228: Refine ownership check with explicit grouping.Clarify the

7-13: Verify that required variables are defined in the common script.The migration functions depend on
KLIPPER_DIR,RATOS_USERNAME, andRATOS_USERGROUPbeing set byratos-common.sh. Please confirm these are exported correctly or add sanity checks/fallbacks to avoid runtime failures.
15-21: Constants declaration is clear and maintainable.Defining URLs, remote name, branch, and commit as constants at the top improves readability and makes updates straightforward.
59-83: Uncommitted changes check is comprehensive.The staged (
--cached) and unstaged (git diff) checks (while ignoring untracked files) enforce a clean working tree before migration. This covers common user scenarios and avoids data loss.
85-120: Remote setup logic correctly handles URL mismatches.Updating or adding the
ratos-forkremote based on existing configurations prevents accidental misconfiguration. Error messages and fallbacks are clear.
151-185: Branch checkout logic is comprehensive.Handling detached HEAD state by creating a temporary branch and then switching or creating the target branch from the fork covers all migration flows. This ensures the working directory ends on the desired branch.
187-216: Commit reset and upstream tracking are correctly implemented.Verifying the target commit exists, performing a hard reset, and setting upstream tracking to the fork branch will align local state precisely with the fork. Error handling is well-scoped.
230-297: Orchestrator flow is clear and fault-tolerant.Distinct exit codes for skip (0), fatal errors (2), and each sub-step (3–7) provide precise failure modes. Sequential checks with early returns maintain idempotency and clear logging for auditability.
299-306: Main execution properly propagates exit codes.Calling
migrate_klipper_repositoryand exiting with its return code ensures that any failure halts the update process with the correct status.

10-17: Retry fallback for realpath/readlink reliability (optional)
Currently$SCRIPT_DIRis determined viarealpath. On systems withoutrealpath, this may fail. Consider falling back toreadlink -for adding a check to surfacing errors explicitly.
19-25: Externalize constants for flexibility
The remote URLs, branch, and commit are hard-coded. If future migrations target different forks or branches, externalizing these as environment variables or a config file would improve maintainability.
126-153: Enhance retry backoff for network fetch
Current retry uses a fixed 5s wait. Introducing exponential backoff (e.g.,sleep $((5 * 2**retry_count))) can improve resilience under intermittent network issues.
222-233: Optimize ownership check performance
Usingfind ... -quitis efficient, but you could further optimize by directly invokingfind -exec chown ... +to skip the explicitchown -Ron success. Alternatively, retainingchown -Ris acceptable for simplicity.
234-302: Streamline migration orchestration
The stepwise exit-code checks are clear, but you could reduce boilerplate by wrapping each step in a helper that handlesreport_status, execution, and error mapping. This will make the flow more DRY.

5-8: Proper non-zero exit on non-root execution
Exiting withexit 1on non-root is correct and prevents false-success.
26-61: Clear differentiation of fatal vs. skip in repository check
check_klipper_repositorycorrectly returns2for fatal errors and1for safe skips. This maps cleanly into the migration flow.
63-87: Confirm ignoring untracked files is intentional
The script ignores untracked files when checking for unstaged changes. Please verify that untracked files should not block migration, as they can still lead to conflicts if not handled.
89-124: Remote management is robust
handle_existing_remotesafely handles creation and URL updates forratos-fork. Good use ofgit remote get-url.
155-189: Branch checkout handles detached HEAD adeptly
The logic covers detached states, local branch existence, and remote branch creation. This ensures idempotent migrations.
191-220: Commit reset and upstream tracking solid
Verifying the target commit before hard-reset prevents unintended states. The fallback warning on upstream tracking failure is a good guard.
303-310: Clean main execution with proper exit propagation

Align error code naming between script and documentation
The docs list both KLIPPER_MIGRATION_FAILED and MIGRATION_FAILED, but the migration script only emits MIGRATION_FAILED in the final error log. Standardize on one code—preferably KLIPPER_MIGRATION_FAILED to match other Klipper-specific codes—and update the script or documentation accordingly.
🤖 Prompt for AI Agents
In LOGGING_SYSTEM.md between lines 189 and 209, the error codes list includes
both KLIPPER_MIGRATION_FAILED and MIGRATION_FAILED, but the migration script
only emits MIGRATION_FAILED. To fix this, standardize the error code naming by
choosing KLIPPER_MIGRATION_FAILED for consistency with other Klipper-specific
codes, then update either the documentation to remove MIGRATION_FAILED or modify
the migration script to emit KLIPPER_MIGRATION_FAILED instead, ensuring both are
aligned.

5-8: Consider logging before exiting on non-rootCurrently this check uses
echobefore sourcing the logging library. After you loadratos-logging.sh, switch tolog_fatalfor consistency, or move the root-check post-logging initialization.
12-20: Handle missing logging library before trap setupYou guard against a missing
ratos-logging.shcorrectly. Once sourced, consider replacing the initialecho/exitwithlog_fatalto centralize error handling in JSON format.
42-56: Ensure all required environment variables are validatedChecking for
KLIPPER_DIR,RATOS_USERNAME, andRATOS_USERGROUPwithlog_fatalis correct. For robust parsing, you might wrap your.envloader inread -rto handle variable values with spaces.
58-64: Make migration parameters configurableDefining URLs, branch, and commit as
readonlyconstants is clear. For future flexibility, consider acceptingTARGET_BRANCHandTARGET_COMMITvia CLI args or environment variables.
102-157: Simplify status check using Git plumbingParsing
git status --porcelainworks but is verbose. You can detect staged/unstaged changes more succinctly with:git diff-index --quiet HEAD -- # unstaged git diff-index --cached --quiet HEAD -- # stagedThis reduces parsing overhead and edge-case handling.

ratos-forkremote is sound. Consider capturing the remote URL once and reusing it to avoid invokinggit remote get-urlmultiple times.
199-229: Improve retry backoff strategyFixed 5-second retries work, but exponential backoff (e.g.,
sleep $((2**retry_count))) can reduce load on flaky networks and speed recovery.
320-336: Optimize ownership checkUsing
find -quitis efficient for detecting mismatches. For large repos, limitingchown -Rto only changed files or using--preserve-rootcan improve performance and safety.
338-412: Document migration exit codes in headerThis function returns codes 0 (skip), 2 (fatal), and 3–8 for sub-step failures. Listing these in a header comment improves maintainability.

Document the MIGRATION_FAILED error code
The migration script emits MIGRATION_FAILED on final failure (log_error … "main" "MIGRATION_FAILED"), but this code isn't listed under “Klipper Migration Error Codes”. Add MIGRATION_FAILED to keep docs in sync with script behavior.

• Add local EXIT trap in checkout_target_branch() function to ensure temporary branches are cleaned up on error exits • Implement cleanup_temp_branch() function that only cleans up on non-zero exit codes • Clear EXIT trap on successful completion to avoid duplicate cleanup • Use existing GIT_TEMP_BRANCH_CLEANUP and GIT_TEMP_BRANCH_CLEANUP_FAILED error codes for consistency • Add shellcheck disable comment for trap-invoked function • Fix variable quoting in cleanup logic This prevents repository pollution with orphaned migration branches when the checkout function fails early due to errors.
• Maintain existing error handling directives (set -euo pipefail and IFS) • Remove duplicate cleanup function definition that was accidentally introduced • Ensure consistency with other bash scripts in the RatOS project • Verify script syntax remains valid after changes This improves portability across different Unix-like systems where Bash may be installed in non-standard locations while maintaining all existing functionality and error handling.
• Move root user check to after logging library initialization • Replace plain echo with log_fatal for consistent structured logging • Use PERMISSION_DENIED error code and script_init context for consistency • Maintain same exit behavior while integrating with unified logging system • Keep pre-logging echo for missing ratos-logging.sh file (necessary exception) This ensures all error messages use the unified logging system wherever possible, improving consistency and enabling proper log aggregation and analysis.
• Add helpful error messages indicating where variables should be defined (in ~/.ratos.env.system) • Implement additional validation for KLIPPER_DIR path existence and accessibility • Add user/group validation using id and getent commands to verify system accounts exist • Use appropriate error codes for different validation failures: - KLIPPER_DIR_NOT_FOUND for missing directory - KLIPPER_DIR_ACCESS_FAILED for permission issues - USER_NOT_FOUND for missing user account - GROUP_NOT_FOUND for missing group • Maintain fast-fail behavior with proper exit codes for script reliability This improves script robustness by catching configuration issues early with clear, actionable error messages that help users understand how to fix problems.

119-127: Consider skipping the step if no scripts exist
Failing the CI whenbash_filesis empty can break branches or forks that don’t include any Bash scripts. You may want to convert this into a warning or skip the step instead of an unconditional failure.
128-152: Parallelize or extend checks for deeper shell validation
Currently the loop validates syntax serially withbash -n. For larger repos you could speed this up withxargs -Pto run checks in parallel. Also consider addingshellcheckorshfmt -dto catch style and semantic issues beyond syntax.

… function • Replace unreliable EXIT trap with explicit cleanup calls on all error exit paths • Implement cleanup_temp_branch_on_error() function for consistent error-path cleanup • Add cleanup calls before return statements on lines 268, 279, and 287 • Remove EXIT trap setup and clearing logic that didn't work in function context • Preserve existing successful completion cleanup behavior (lines 292-300) • Maintain all existing error codes, logging behavior, and shellcheck compliance Problem Fixed: - EXIT traps set within functions only trigger on script exit, not function return - Temporary branches were not cleaned up when function returned early due to errors - This could leave orphaned migration branches in the repository Solution Benefits: - Reliable cleanup on all function exit paths (both error and success) - Clear, explicit cleanup logic that's easy to understand and maintain - No dependency on trap mechanisms that behave differently in function contexts - Consistent error handling and logging throughout the function
This commit introduces a new step to the CI workflow (`ci.yml`) that performs a syntax check on all bash scripts within the repository. The new CI job: - Identifies all `.sh` files and files with a bash shebang (`#!/bin/bash` or `#!/usr/bin/env bash`). - Excludes common directories like `node_modules`, `.git`, and `.augment`. - Uses `bash -n` to perform a non-destructive syntax validation for each identified script. - Reports any syntax errors found, providing detailed output to aid in debugging. This addition aims to proactively catch and prevent syntax errors in shell scripts before they are merged, improving code quality and reliability.
…RR trap • Add function-level ERR trap to catch unexpected failures and signals • Provide defense-in-depth protection beyond explicit cleanup calls • Handle scenarios like unhandled command failures, SIGINT/SIGTERM interruptions • Clear ERR trap on successful completion to prevent interference • Maintain all existing explicit cleanup calls for known error paths • Preserve current successful completion cleanup behavior Benefits: - Catches unexpected Git command failures (git symbolic-ref, git show-ref, etc.) - Provides signal handling protection during Git operations - Minimal complexity addition with meaningful safety improvement - Works alongside existing explicit cleanup for comprehensive coverage - Ensures temporary branches are cleaned up in all failure scenarios This enhancement addresses the gap where unexpected failures could leave temporary branches orphaned, providing robust cleanup reliability without compromising the clear explicit error handling approach.
Part 1: Extended official remote URL detection • Support additional Git URL formats beyond HTTPS and SSH shorthand: - SSH protocol: ssh://[email protected]/Klipper3d/klipper.git - Git protocol: git://github.com/Klipper3d/klipper.git • Replace exact string matching with array-based pattern matching • Maintain existing HTTPS and SSH shorthand support • Use OFFICIAL_KLIPPER_URL constant for maintainability • Improve code readability with clear URL format documentation Part 2: Implemented distinct error codes for check_uncommitted_changes() • Directory access errors now return exit code 2 (was 1) • Uncommitted changes detection now returns exit code 3 (was 1) • Add comprehensive function documentation with return code meanings • Update migrate_klipper_repository() to handle new exit codes appropriately • Preserve all existing logging behavior and error messages • Enable better error differentiation for debugging and troubleshooting Benefits: - Broader compatibility with different Git URL configurations - Clear distinction between access failures and uncommitted changes - Improved error handling and debugging capabilities - Better integration with calling code error handling logic - Maintained backward compatibility for existing functionality
…tion • Change from specific path './src/node_modules/*' to generic pattern '*/node_modules/*' • Exclude ANY directory named node_modules at any level in the repository hierarchy • Improve CI performance by avoiding traversal of potentially large dependency directories • Provide more robust exclusion that works regardless of where node_modules directories are located • Apply fix to both .sh file discovery and shebang-based script discovery commands This prevents the find command from scanning into any node_modules directories recursively, improving CI performance and providing more comprehensive exclusion coverage.
…outputs • Replace 'grep -l' with 'grep -q' to prevent mixed delimiter confusion • Use proper pruning syntax '-path "*/node_modules/*" -prune -o' for more efficient directory exclusion • Eliminate duplicate file outputs caused by both grep -l and find -print0 printing filenames • Ensure consistent null-terminated output for proper while loop processing • Improve performance by making grep exit immediately upon finding first match Problem Fixed: - grep -l was printing filenames with newlines while find -print0 was printing with null terminators - This caused files to be printed twice with different delimiters, confusing the input processing - grep -l also processed entire files even after finding the first match, reducing efficiency Solution Benefits: - Clean, null-terminated list of bash script files without duplicates - More efficient directory traversal with proper pruning - Consistent delimiter handling for reliable script processing
• Skip bash validation step gracefully when no scripts exist instead of failing • Change from error exit (exit 1) to successful exit (exit 0) with informative message • Add clear messaging explaining this is normal for branches/forks without shell scripts • Maintain existing validation behavior when bash scripts do exist • Improve CI reliability for legitimate code changes that don't include bash scripts Problem Fixed: - CI workflow was failing unnecessarily when no bash scripts were found - This broke legitimate branches or forks that don't contain any bash scripts - Created false negative CI results for valid code changes Solution Benefits: - CI now passes successfully for repositories without bash scripts - Clear, informative messaging explains why validation was skipped - Maintains strict validation when bash scripts are present - Improves overall CI reliability and reduces false failures
• Implement parallel validation using xargs -P for faster execution • Determine optimal parallelism based on CPU cores (max 8 for GitHub Actions) • Replace serial for-loop with parallel processing to reduce CI execution time • Add proper error handling and exit code propagation in parallel execution • Maintain clear error reporting that identifies which specific scripts failed • Use temporary files to collect validation results from parallel processes • Export validation function for use by xargs subprocess execution • Preserve existing validation behavior and error message formatting Performance Improvements: - Parallel execution scales with available CPU cores - Significantly faster validation for repositories with many shell scripts - Optimal resource utilization without overwhelming GitHub Actions runners - Maintains backward compatibility with existing script validation expectations Technical Implementation: - Use nproc to detect available CPU cores, capped at 8 for stability - Export bash function for subprocess access in parallel execution - Temporary files for result aggregation from parallel processes - Proper cleanup of temporary files regardless of success/failure outcome - Clear progress indication with parallel process count logging
The `find` commands used to locate bash scripts in the CI workflow previously used `./.git/*` to exclude the Git repository directory. This pattern is less robust as it specifically targets a `.git` directory directly under the current working directory. By changing the pattern to `*/.git/*`, the `find` command will now correctly exclude any `.git` directory found at any depth within the repository. This ensures that internal Git files, including those from submodules or other nested Git structures, are consistently ignored by the bash script linter.

5-5: Portability: realpath dependency
The script assumesrealpathis available. Consider adding a check or fallback toreadlink -fto handle environments whererealpathmay be missing.Example diff:
+if ! command -v realpath >/dev/null; then + if command -v readlink >/dev/null; then + REALPATH_CMD="readlink -f" + else + log_fatal "Neither realpath nor readlink is available" "script_init" "COMMAND_NOT_FOUND" + exit 1 + fi +else + REALPATH_CMD="realpath" +fi +SCRIPT_DIR=$( cd -- "$( dirname -- "$($REALPATH_CMD "${BASH_SOURCE[0]}")" )" &> /dev/null && pwd )
232-262: Fetch retry logic
The retry loop forgit fetchis well-implemented. To further improve resilience, you might incorporate exponential backoff and jitter between retries.Example diff:
- if [ $retry_count -lt $max_retries ]; then - log_info "Retrying in 5 seconds..." "fetch_fork" - sleep 5 + if [ $retry_count -lt $max_retries ]; then + backoff=$((5 * retry_count)) + log_info "Retrying in $backoff seconds..." "fetch_fork" + sleep $backoff
264-339: Branch checkout and cleanup
checkout_target_branch()handles detached HEAD states, branch creation, and cleanup via anERRtrap. Clearing the trap on success avoids side effects. Consider usinggit -C "$KLIPPER_DIR"to eliminate repeatedcdcalls.Example diff:
-execute_with_logging git checkout -b "$temp_branch" +execute_with_logging git -C "$KLIPPER_DIR" checkout -b "$temp_branch"

1-3: Shebang and strict mode configuration
Using#!/usr/bin/env bashalongsideset -euo pipefailand a safeIFSis a solid foundation for robust scripting.
9-14: Script logging library sourcing
Sourcingratos-logging.shwith proper existence checks andSC1091suppression is implemented correctly.
23-27: Root privilege enforcement
The check for$EUIDfollowed bylog_fatalandexit 1ensures the script is only run as root. This is handled appropriately.
29-35: Common functions sourcing
Sourcingratos-common.shwith existence validation aligns with project conventions.
44-57: Environment variable validation
Clear checks forKLIPPER_DIR,RATOS_USERNAME, andRATOS_USERGROUPwith distinct fatal logs are present. This validates critical preconditions effectively.
60-68: Klipper directory existence and access checks
Verifying thatKLIPPER_DIRexists and is readable/executable before proceeding prevents downstream failures.
71-79: System user/group existence checks
Usingidandgetent groupto validateRATOS_USERNAMEandRATOS_USERGROUPis robust and concise.
82-88: Migration constants declaration
Defining URLs, remote names, branch, and commit asreadonlyconstants prevents accidental modification. This approach is solid.
89-142: Repository source validation
check_klipper_repository()correctly differentiates between fatal errors (return code 2) and skip conditions when the remote doesn't match (return code 1). URL matching covers multiple common formats.
144-190: Uncommitted changes detection
check_uncommitted_changes()leverages Git plumbing commands to detect both staged and unstaged changes, returning discrete codes for directory access errors and uncommitted changes.
191-230: RatOS fork remote handling
handle_existing_remote()safely adds or updates theratos-forkremote, with clear logging and error mapping. The approach avoids redundant Git calls by caching the URL.
341-373: Reset to specific commit
The function verifies the commit’s existence, resets hard, and then sets upstream tracking. Logging for a failed upstream setting as a warning is appropriate.
375-391: Ownership correction
fix_klipper_ownership()usesfindto detect ownership mismatches and applieschownonly when necessary, reducing unnecessary recursive calls.
393-535: Migration orchestration
migrate_klipper_repository()sequences all steps with precise error-code handling and maps them to meaningful logs. The distinction between skip (0), fatal, and specific error codes aligns with best practices.
537-552: Script entrypoint and cleanup
The main execution block captures the return code, generates a summary, and exits with the appropriate status. Logging ensures traceability.
The CI workflow uses a two-step process to identify bash scripts for syntax validation. The second step specifically targets files with a bash shebang that are not explicitly `.sh` files. Previously, this step would broadly search for any file containing a shebang, relying on a later `if` condition to exclude files with a `.sh` extension. This commit adds `-not -name "*.*"` to the `find` command in this step. This ensures that the `find` command directly filters for files that explicitly lack a file extension while still possessing a bash shebang. This makes the script identification process more precise, preventing unnecessary processing of files with other extensions that might coincidentally contain a shebang string.
…llbacks • Implement portable script directory resolution with multiple fallback methods • Primary method: Use realpath when available (preferred for accuracy and symlink resolution) • Fallback method: Use readlink -f as backup option for systems without realpath • Ultimate fallback: Use basic dirname approach for maximum compatibility on minimal systems • Add proper error handling with clear error message when all methods fail • Maintain same functionality as original realpath approach when available • Preserve existing SCRIPT_DIR variable name for full compatibility • Follow existing code style and maintain shellcheck compliance Compatibility Improvements: - Supports systems without realpath (some minimal Linux distributions, older macOS) - Graceful degradation through multiple fallback methods - Clear error reporting when path resolution completely fails - Maintains absolute and canonical path resolution when possible - Ensures script works across diverse Unix-like environments Technical Implementation: - Use command -v for portable command availability checking - Preserve original directory resolution logic structure - Handle edge cases with appropriate error messages - Early exit with clear error message before logging system is available
…ctory changes • Remove initial 'cd $KLIPPER_DIR' approach in checkout_target_branch() function • Replace with explicit '-C $KLIPPER_DIR' flags on all individual git commands • Update all git commands to use explicit directory specification: - git symbolic-ref HEAD - git checkout -b (temporary branch creation) - git show-ref --verify --quiet (branch existence check) - git checkout (existing branch switch) - git checkout -b (new branch from remote) - git branch -D (cleanup commands in both error and success paths) • Eliminate directory access validation at function start (no longer needed) Benefits: - Eliminates side effects: Working directory of calling context remains unchanged - Improves error recovery: ERR trap cleanup doesn't need to worry about directory state - Enhances code clarity: Each git command explicitly specifies its target directory - Reduces complexity: No need for directory access validation at function start - Better isolation: Function becomes more self-contained and predictable - Maintains all existing error handling and logging behavior - Preserves ERR trap cleanup mechanism for temporary branches Technical Implementation: - All git commands now use '-C $KLIPPER_DIR' for explicit directory context - Cleanup function updated to use explicit directory specification - Function behavior remains identical after the change - No changes to error codes, logging, or trap mechanisms

Thereadlink -ffallback may not support-fon some platforms (e.g., macOS). Consider testingreadlink -fbefore assuming it works, or wrap it in a subshell test to fall back only whenreadlink -factually succeeds.
52-83: DRY up environment-variable validation
The repeated blocks for checkingKLIPPER_DIR,RATOS_USERNAME, andRATOS_USERGROUPwork, but could be refactored into a helper function to reduce duplication.
97-103: Consider making constants configurable
Defining URLs, branch, and commit asreadonlyis good practice; optionally, allow overriding via environment variables for testing or alternate forks.
385-401: Ownership check needs explicit grouping
Thefindexpression could misinterpret operator precedence. Wrap the user/group tests in parentheses before-quitto avoid unexpected matches.
403-545: Orchestrator logs duplicate errors
Each step logs errors internally and then the orchestrator logs another on failure, leading to duplicate messages. Consider returning error codes without internal logging for fatal steps and let the orchestrator handle the final log.

288-302: Consider using-prunefor faster script discovery
Thefind … -not -path …approach works but can be slow on large repos. You could instead prune unwanted dirs:- find "$VALIDATION_DIRECTORY" -name "*.sh" -type f "${exclusion_args[@]}" -print0 + find "$VALIDATION_DIRECTORY" \ + \( -path "*/node_modules/*" -o -path "*/.git/*" -o -path "./.augment/*" \) -prune -o \ + -name "*.sh" -type f -print0This reduces the search footprint.
318-322: Simplify parameter expansion quoting
Current expansion uses nested quotes in${script#"$VALIDATION_DIRECTORY"/}which is less idiomatic and may have edge-case behavior. Use:display_path="${script#$VALIDATION_DIRECTORY/}"This is clearer and avoids quoting pitfalls.
323-327: Avoid non-portablesha256sumdependency
Not all environments (e.g., macOS) providesha256sum. Consider replacing with a portablemktemp-based approach for unique filenames:- script_hash=$(echo "$script" | sha256sum | cut -d' ' -f1) - local output_file="$output_dir/validation_$script_hash.out" + local output_file + output_file=$(mktemp "$output_dir/validation_XXXXXX.out")This eliminates the external checksum dependency.

🛠️ Refactor suggestion
Add cleanup trap for temporary files on exit
If the script is interrupted, the temp files and directory linger. Introduce a trap 'rm -rf "$validation_results" "$validation_errors" "$output_dir"' EXIT after creation to ensure cleanup regardless of exit code.
🤖 Prompt for AI Agents
In scripts/validate-bash-syntax.sh around lines 379 to 387, temporary files and
directories are created but not cleaned up if the script is interrupted. Add a
trap command immediately after creating the temp files and directory: trap 'rm
-rf "$validation_results" "$validation_errors" "$output_dir"' EXIT to ensure
these temporary resources are removed on any script exit.
