  • Fix typo in comment (line 59): "blow" → "below"
  • Remove trailing whitespace in comment (line 187)
  • Fix typo in gettext (line 423): "charater" → "character"
  • Fix typo in error message (line 480): remove double period
  • Add errcode() to ereport() calls (lines 582, 584-585, 604-605):
    • ERRCODE_STRING_DATA_RIGHT_TRUNCATION for length check
    • ERRCODE_INVALID_PARAMETER_VALUE for NLS errors
  • Optimize nls_case_conversion() by caching strlen() result Change O(N²) to O(N) performance complexity
  • Replace magic numbers with character constants:
    • 97, 122 → 'a', 'z'
    • 65, 90 → 'A', 'Z'

📝 Walkthrough

Walkthrough

Comment and string corrections in NLS validation functions, including standardized error reporting with explicit SQLSTATE codes for parameter truncation and invalid parameter scenarios, plus loop optimization reducing strlen calls through a local length variable in character case conversion.

Changes

Cohort / File(s) Summary
Error Reporting & Code Quality
src/backend/utils/misc/ivy_guc.c		 Fixed typos in comments (blow → below, charater → character). Added explicit SQLSTATE codes: ERRCODE_STRING_DATA_RIGHT_TRUNCATION for exceeding 255 character limit; ERRCODE_INVALID_PARAMETER_VALUE for invalid NLS data access. Introduced local len variable in nls_case_conversion to avoid repeated strlen calls; replaced repeated range checks with character constants ('a'..'z', 'A'..'Z').
