ISSUE 1: Missing -v tmpdir variable in 5 awk blocks:
- analyze_headers() (line 773)
- analyze_entry_points() (line 868)
- analyze_url_entropy() (line 1095)
- analyze_request_timing() (line 1149)
- detect_false_positives() top sites analysis (line 1960)
These awk blocks were trying to use tmpdir variable without it being passed in,
causing 'tmpdir' to be treated as empty string or undefined variable. Files would
be written to root directory with broken names, silently failing.
ISSUE 2: Process substitution inefficiency in detect_threats():
- Line 1026: Changed from '< <(cat file)' to '< file'
- Process substitution creates unnecessary pipe and subshell
ISSUE 3: Missing close() statements for file handles in awk:
- analyze_headers(): Added close() for header_anomalies.txt
- analyze_entry_points(): Added close() for 3 output files
- analyze_url_entropy(): Added close() for fuzzing_ips.txt
- analyze_request_timing(): Added close() for timing_anomalies.txt
- detect_false_positives(): Added close() for 3 output files
FILE OUTPUT IMPACT:
All these functions now properly:
- Have tmpdir variable available
- Create files in correct temp directory
- Close file handles properly for buffer flushing
- Avoid unnecessary process substitutions
VERIFIED:
- Syntax check: PASSED
- All tmpdir references now have corresponding -v definitions
- All file-writing awk blocks have explicit close() calls
