 Analysis Ukuguqulwa Frequency Ukubonisa i-code hotspots Ukusetyenziswa kwedatha ye-version control Ukucaciswa kwindawo ezisebenzayo Ukubalwa kweCode Churn Ukucaciswa ️ https://hackernoon.com/refactoring-021-remove-dead-code?embedable=true Umzekelo Yintoni i-anti-code eyenzayo. Uyakwazi ukufumana ikhowudi obuthandayo kunye neengxaki ezininzi, iinkqubo ezininzi kunye neengxaki ze-naming. Uyazi i-Uncle Bob i-motto yokuzonwabisa i-camping engcono kunokuba ngexesha lokufumana. I-instinct yakho ye-refactoring ifumaneka, kwaye uthatha iintsuku ukucacisa. Ngaba ungenza imveliso, kodwa ungenza ixesha yakho. I-code ebomvu kuphela ifumaneka xa . you need to change it Ikhowudi olufanelekileyo, nangokuthi ifakwe ngokufanelekileyo, ayidla umveliso wakho. I-technical debt yokwenene kwi-code hotspots: iindawo ezinxulumene kunye ne-frequently modified. Izixhobo ezininzi ze-codebases zihlanganisa i-extreme distribution apho . I-5% ye-code ibonelela i-90% yeengxaki Ngaphandle kokuhlolwa kwihlabathi ye-version control, ungenza ukucacisa i-coding ye-massy efanelekileyo. Uya kukugcina ukuguqulwa kwimeko embalwa ngelixa iingxaki zayo ziye zithintela. Ukuba unemibuzo yobuchwepheshe, kufuneka uqhagamshelane kunye ne-code ye-low quality kunye ne-high change frequency. Yonke okuzenzakalelayo i-optimization ephakamileyo efanelekileyo njenge-artisancy. Sample Ikhodi Iingxaki # This authentication module hasn't changed in 3 years
# It's deprecated and will be removed next quarter
# But you spend a week "improving" it

class LegacyAuthenticator:
    def authenticate(self, user, pwd):
        # Original messy code from 2019
        if user != None:
            if pwd != None:
                if len(pwd) > 5:
                    # Complex nested logic...
                    result = self.check_db(user, pwd)
                    if result == True:
                        return True
                    else:
                        return False
        return False

# After your "refactoring" (that nobody asked for):
class LegacyAuthenticator:
    def authenticate(self, user: str, pwd: str) -> bool:
        if not self._is_valid_input(user, pwd):
            return False
        return self._verify_credentials(user, pwd)

    def _is_valid_input(self, user: str, pwd: str) -> bool:
        return user and pwd and len(pwd) > 5

    def _verify_credentials(self, user: str, pwd: str) -> bool:
        return self.check_db(user, pwd)

# Meanwhile, the actively developed payment module
# (modified 47 times this month) remains a mess
 Ngathi 🙂 # You analyze git history first:
# git log --format=format: --name-only | 
# grep -E '\.py$' | sort | uniq -c | sort -rn

# Results show PaymentProcessor changed 47 times this month
# And it does not have good enough coverage
# LegacyAuthenticator: 0 changes in 3 years

# Focus on the actual hotspot:
class PaymentProcessor:
    # This gets modified constantly and is hard to change
    # REFACTOR THIS FIRST
    def process_payment(self, amount, card, user, promo_code,
                       installments, currency, gateway):
        # 500 lines of tangled logic here
        # Changed 47 times this month
        # Every change takes 2+ days due to complexity
        pass

# Ignore stable legacy code
# But you can use IA to cover existing functionality
# With acceptance tests validated by a human product owner

class LegacyAuthenticator:
    # Leave this ugly code alone
    # It works, it's stable, it's being deprecated
    # Your time is better spent elsewhere
    def authenticate(self, user, pwd):
        if user != None:
            if pwd != None:
                if len(pwd) > 5:
                    result = self.check_db(user, pwd)
                    if result == True:
                        return True
        return False
 Ukucinga [X] I-Semi-Automatic Uyakwazi ukucacisa lo mnyama ngokuchasene ne-version control history yakho. Ukucacisa iifayile ezintsha ngokubanzi kwaye uqhagamshelane oku kunye ne-code quality metrics. Izixhobo ezifana , git log analytics, okanye scripts eyongezelelweyo zibonisa i hotspots yakho zayo. Ukucinga Ukucinga i-code ukuba uqhagamshelane ngokushesha. Ukucinga iimeko Kwiimeko, kufuneka refactor ikhowudi ebonakalayo xa: 
 
 
 
 
 Ukulungiselela iimveliso ezintsha kufuneka iimveliso ezintsha Ukucaciswa kwebhizinisi kufuneka iifayile Ukucaciswa kwe-regulatory requires changes Uya kuqhagamshelane iimpawu ze-dormant Inyaniso olufanelekileyo ezisekelwe kwiinkcukacha ezifanelekileyo, ngaphandle kweengxaki. iintsuku ️ 
 
 Uluhlu Technical Umgangatho [X] Ubunzima Yintoni i-bijection yinto ebalulekileyo ️ Xa utshintshe a phakathi kwe-code yakho kunye ne-real-world behavior, uya kufumana iindawo ezithile ze-system yakho ziya kubandakanya ngempumelelo kunezinye. Ukucinga Ukucinga Yintoni, kufuneka uqhagamshelane le mveliso. Ukucinga Xa uqhagamshelane ikhowudi ebonakalayo, uqhagamshelane ukuxhaswa phakathi kweengxaki yentuthuko kunye neengxaki yentuthuko yentuthuko. Uxhomekeka yonke ikhowudi ngokufanelekileyo kwimodeli yakho yokuzonwabisa, kodwa kwihlabathi esemthethweni ibonisa iimodeli ezininzi zokusetyenziswa apho i-percentage elincinci ye-code ibhagamshelane ne-most changes. Uyakwazi ukuvelisa kwihlabathi emangalisayo apho zonke iinkqubo zihlanganisa ngamanani. Iimveliso Zonke i-code generators zibonisa i-refactorings ngaphandle kokufunda i-changing frequency. Izixhobo ze-AI kunye ne-linters zihlanganisa ikhowudi ngokucacileyo kwaye zixazulule iimveliso ezisekelwe kwimveliso kuphela, ngaphandle kokusetyenziswa. Musa ukufikelela kwihlabathi ye-version control yakho ukuze ufumane iingcebiso ezininzi ezininzi. Nceda uqhagamshelane. Ukucaciswa I-AI ingathanda zonke i-function eside okanye i-conditional epheleleyo, ukuthetha i-methode ye-500-line ye-legacy efanayo ne-function eyenziwe ngosuku. Ukucinga I-AI inokunceda ukuguqula le ngxaki ye-code ukuba unike ne-context efanelekileyo. Ufuna ukunikezela idatha ye-version control ezibonisa i-changing frequencies. Ngaphandle kwelinye ulwazi, i-AI uya kwenza iingxaki ezininzi ezinokuquka abantu: ukunceda i-refactorings ezisekelwe kuphela kwi-code structure. Zama! Qinisekisa: I-AI Assistants ikwenza iingxaki ezininzi
