分析

进出、链、出

df进出=df[  df['tickKind'].isin( [FuncEnter,FuncReturn] )  ]#代码中，只有在函数进入时，计算了链条长度 并写磁盘
df入=df[  df['tickKind'].isin( [FuncEnter] )  ]
df链=df入# 函数本地时长 应 用  出时的计数器的值 
df出=df[  df['tickKind'].isin( [FuncReturn] )  ]

从funcEnterId查funcId的字典

fei2fi = df链.set_index('funcEnterId')['funcId'].to_dict()
type(fei2fi), list(fei2fi.items())[0:10] 

(dict,[(0, 725),(1, 576),(2, 355),(3, 2237),(4, 165),(5, 355),(6, 2237),(7, 165),(8, 355),(9, 2237)])

fei2fn = df链.set_index('funcEnterId')['funcName'].to_dict()
type(fei2fn), list(fei2fn.items())[0:10] 

(dict,[(0, 'llvm::cl::getGeneralCategory'),(1, 'llvm::cl::OptionCategory::registerCategory'),(2, 'llvm::ManagedStaticBase::RegisterManagedStatic'),(3, 'llvm::llvm_is_multithreaded'),(4, 'getManagedStaticMutex'),(5, 'llvm::ManagedStaticBase::RegisterManagedStatic'),(6, 'llvm::llvm_is_multithreaded'),(7, 'getManagedStaticMutex'),(8, 'llvm::ManagedStaticBase::RegisterManagedStatic'),(9, 'llvm::llvm_is_multithreaded')])

构造字段funcIdSeq

#利用字典fei2fi ，将输入 funcEnterIdSeqK 转为 funcIdSeqK
def funcEnterIdSeq2funcIdSeq(funcEnterIdSeqK:str):    fis=[]fiK=Nonefor feiK_str in funcEnterIdSeqK.split("#"):if feiK_str == '': continuefeiK=int(feiK_str) # feiK 必须是数字格式，如果不是 正好报错fiK=fei2fi[feiK] # feiK 必须在字典fei2fi中，如果不在 正好报错fis.append(fiK)fiKStr_ls=  [ f'{fiK}' for fiK in fis]return '#'.join(fiKStr_ls)

#利用字典fei2fn ，将输入 funcEnterIdSeqK 转为 funcNameSeqK
def funcEnterIdSeq2funcNameSeq(funcEnterIdSeqK:str):    fns=[]fnK=Nonefor feiK_str in funcEnterIdSeqK.split("#"):if feiK_str == '': continuefeiK=int(feiK_str) # feiK 必须是数字格式，如果不是 正好报错fnK=fei2fn[feiK] # feiK 必须在字典fei2fi中，如果不在 正好报错fns.append(fnK)return '#'.join(fns)

#测试函数funcEnterIdSeq2funcIdSeq
# funcEnterIdSeqK="#3#2#1#"
# funcEnterIdSeq2funcIdSeq(funcEnterIdSeqK),funcEnterIdSeq2funcNameSeq(funcEnterIdSeqK)

df进出['funcIdSeq']=df进出['funcEnterIdSeq'] .apply(lambda feisJ:  funcEnterIdSeq2funcIdSeq(feisJ) )df入['funcIdSeq']=df入['funcEnterIdSeq'] .apply(lambda feisJ:  funcEnterIdSeq2funcIdSeq(feisJ) )
df链=df入df出['funcIdSeq']=df出['funcEnterIdSeq'] .apply(lambda feisJ:  funcEnterIdSeq2funcIdSeq(feisJ) )

df进出['funcNameSeq']=df进出['funcEnterIdSeq'] .apply(lambda feisJ:  funcEnterIdSeq2funcNameSeq(feisJ) )df入['funcNameSeq']=df入['funcEnterIdSeq'] .apply(lambda feisJ:  funcEnterIdSeq2funcNameSeq(feisJ) )
