Fix critical issues in Bash scripts and build system
Addresses issue #18 by implementing comprehensive fixes for: 1. Enhanced GitHub Workflows: - Added proper error handling with set -euo pipefail - Implemented explicit error checking for all commands - Improved coverage pipeline with validation steps - Added timeout and cleanup mechanisms 2. Improved Makefile Robustness: - Added graceful dependency management for utils/Makefile - Implemented auto-installation targets for missing dependencies - Enhanced error handling with descriptive messages - Added validation targets for build environment 3. Security Enhancements: - Added input parameter validation - Implemented safer shell scripting practices - Added explicit error handling for external commands - Proper cleanup mechanisms on failures 4. Build System Testing: - Created comprehensive validation script (scripts/validate-build.sh) - Added dependency checking and environment validation - Improved error reporting and logging Key improvements: - All shell scripts now use proper error handling - Build failures are caught early with clear error messages - Missing dependencies are handled gracefully - Build system includes comprehensive validation - Enhanced maintainability and contributor experience Fixes #18 Signed-off-by: Kallal Mukherjee <[email protected]>

# Fix Critical Issues in Bash Scripts and Build System
2+
3+
## Problem Summary
4+
The current repository contains several critical issues in the Bash-related code including GitHub workflows, Makefiles, and shell commands that can lead to build failures, security vulnerabilities, and maintenance problems.
5+
6+
## Issues Identified
7+
8+
### 1. 🚨 **Critical: Unsafe Pipeline Construction in Coverage Workflow**
9+
**File**: `.github/workflows/ci-go-cover.yml`
10+
**Issue**: The coverage pipeline uses potentially unsafe command chaining without proper error handling:
11+
```bash
12+
go test -short -cover | grep -o "coverage:.*of statements$" | python scripts/cov.py
13+
```
14+
**Risk**: Silent failures in the pipeline where `grep` or `python` could fail without proper error detection.
15+
16+
### 2. ⚠️ **Build System Fragility**
17+
**File**: `utils/Makefile`
18+
**Issue**: Hard failure when `zek` dependency is missing with poor error recovery:
19+
```makefile
20+
zek ?= $(shell command -v zek)
21+
ifeq ($(strip $(zek)),)
22+
$(error zek not found. To install zek: 'go install github.com/miku/zek/cmd/zek@latest')
23+
endif
24+
```
25+
**Risk**: Breaks the entire build process instead of providing graceful degradation or auto-installation.
26+
27+
### 3. 🔒 **Security: Missing Error Handling in GitHub Workflows**
28+
**Files**: `.github/workflows/ci-go-cover.yml`, `.github/workflows/ci.yml`
29+
**Issue**: No `set -euo pipefail` or equivalent error handling in shell scripts.
30+
**Risk**: Commands may fail silently, leading to false positive test results.
31+
32+
### 4. 📦 **Dependency Management Issues**
33+
**File**: `utils/Makefile`
34+
**Issue**: External dependency (`zek`) is required but not automatically managed.
35+
**Risk**: New contributors face immediate build failures without clear resolution paths.
36+
37+
### 5. 🧪 **Missing Test Coverage for Build Scripts**
38+
**Issue**: No validation or testing of the Makefile targets and GitHub workflow scripts.
39+
**Risk**: Build system regressions go unnoticed until they cause production issues.
40+
41+
## Proposed Solutions
42+
43+
### 1. **Enhanced GitHub Workflows**
44+
- Add proper error handling with `set -euo pipefail`
45+
- Implement proper exit status checking for pipeline commands
46+
- Add timeout mechanisms for long-running processes
47+
- Separate concerns for better debugging
48+
49+
### 2. **Improved Makefile Robustness**
50+
- Add auto-installation targets for missing dependencies
51+
- Implement graceful degradation when optional tools are missing
52+
- Add validation targets to check system requirements
53+
- Better error messages with actionable instructions
54+
55+
### 3. **Security Enhancements**
56+
- Validate all input parameters
57+
- Use safer shell scripting practices
58+
- Add explicit error handling for all external commands
59+
- Implement proper cleanup mechanisms
60+
61+
### 4. **Build System Testing**
62+
- Add validation tests for Makefile targets
63+
- Create integration tests for GitHub workflows
64+
- Implement pre-commit hooks to validate script changes
65+
66+
## Impact Assessment
67+
- **Severity**: High - Affects build reliability and security
68+
- **Scope**: All contributors and CI/CD processes
69+
- **Urgency**: High - Should be fixed before next release
70+
71+
## Acceptance Criteria
72+
- [ ] All shell scripts use proper error handling (`set -euo pipefail`)
73+
- [ ] GitHub workflows have explicit error checking for all commands
74+
- [ ] Makefiles provide graceful handling of missing dependencies
75+
- [ ] Build system includes validation and testing
76+
- [ ] Documentation updated with troubleshooting guides
77+
- [ ] All existing tests pass with new implementations
78+
79+
## Additional Context
80+
This issue was identified during a comprehensive audit of the repository's build system. The changes will improve reliability for all contributors and reduce the likelihood of silent failures in CI/CD processes.
