Description
For example, in the collation callback twostr objects (string1 andstring2) are created usingPyUnicode_FromStringAndSize. Error handling should happen directly after each call toPyUnicode_FromStringAndSize:
cpython/Modules/_sqlite/connection.c
Lines 1870 to 1875 in0cb6b9b
| string1=PyUnicode_FromStringAndSize((constchar*)text1_data,text1_length); | |
| string2=PyUnicode_FromStringAndSize((constchar*)text2_data,text2_length); | |
| if (!string1|| !string2) { | |
| gotofinally;/* failed to allocate strings */ | |
| } |
Other cases where error handling is not done immediately after the API has been used:
