Splits realtime_events.py into pos_next/events/{stock,invoice,pos_profile}.py. Refactors utils.py into pos_next/utils/version.py and adds package init. Updates hooks.py to reflect new paths. * refactor: apply PR review suggestions for security and structure - Move API methods to `pos_next/api/` (branding, credit sales). - Split monolithic validation methods in BrainWiseBranding, POSClosingShift, POSCoupon, ReferralCode. - Implement secure signature verification in Branding (recalculate HMAC). - Move hardcoded branding secrets to `pos_next/config/security.py`. - Optimize database queries (replace loops with `get_all`, use atomic updates). - Maintain backward compatibility for API endpoints and return structures. - Restore `get_csrf_token` utility. - Fix regression in `credit_sales.py` to restore original API contract. - Fix regression in `branding.py` to respect disabled state. - Fix regression in `referral_code.py` to restore duplicate check. * refactor: add comments and docstrings for better maintainability - Add detailed docstrings to BrainWiseBranding, POSClosingShift, POSCoupon, ReferralCode. - Explain security mechanisms (HMAC, Master Key) in branding. - Document atomic update logic in POSCoupon. - Explain reconciliation logic in POSClosingShift. - Document API endpoints in credit_sales and branding. * refactor: finalize POS Next backend cleanup and security hardening - Consolidate all refactoring from PR #43 (modularization, validation splitting). - Update copyright to 2025 across all touched files. - Restore deleted keys in Branding API (`_c`, `_s`) and Credit Sales API (`net_balance`, `total_outstanding`) for frontend compatibility. - Restore `cancel_credit_journal_entries` logic to maintain data integrity. - Add backward compatibility shims for API endpoints. - Document complex logic with comprehensive docstrings. - Fix regression in branding auto-enable logic. - Ensure all new files have proper copyright headers. - Update `hooks.py` to reflect new file structure. --- pos_next/api/branding.py | 400 ++++---- pos_next/api/credit_sales.py | 868 +++++++----------- pos_next/api/utilities.py | 5 +- pos_next/api/utils/__init__.py | 2 + pos_next/api/utils/currency.py | 30 + pos_next/config/security.py | 5 + pos_next/events/invoice.py | 46 + pos_next/events/pos_profile.py | 57 ++ .../{realtime_events.py => events/stock.py} | 91 +- pos_next/hooks.py | 28 +- .../brainwise_branding/brainwise_branding.py | 616 +++++-------- .../pos_closing_shift/pos_closing_shift.py | 187 ++-- .../pos_next/doctype/pos_coupon/pos_coupon.py | 103 ++- .../doctype/pos_settings/pos_settings.py | 63 +- .../doctype/referral_code/referral_code.py | 285 +++--- pos_next/utils/__init__.py | 4 + pos_next/{ => utils}/install.py | 0 pos_next/{ => utils}/uninstall.py | 0 pos_next/{ => utils}/validations.py | 0 pos_next/{utils.py => utils/version.py} | 3 +- 20 files changed, 1264 insertions(+), 1529 deletions(-) create mode 100644 pos_next/api/utils/__init__.py create mode 100644 pos_next/api/utils/currency.py create mode 100644 pos_next/config/security.py create mode 100644 pos_next/events/invoice.py create mode 100644 pos_next/events/pos_profile.py rename pos_next/{realtime_events.py => events/stock.py} (53%) create mode 100644 pos_next/utils/__init__.py rename pos_next/{ => utils}/install.py (100%) rename pos_next/{ => utils}/uninstall.py (100%) rename pos_next/{ => utils}/validations.py (100%) rename pos_next/{utils.py => utils/version.py} (95%) diff --git a/pos_next/api/branding.py b/pos_next/api/branding.py index a942ab58..ad933af8 100644 --- a/pos_next/api/branding.py +++ b/pos_next/api/branding.py @@ -1,221 +1,221 @@ # Copyright (c) 2025, BrainWise and contributors # For license information, please see license.txt -""" -BrainWise Branding API -Provides secure branding configuration and validation endpoints -""" -
