关于python源码实现sqlite API 的问题
我想查看sqlite3 的连接是怎么实现的。可是源码只有 1 行__init.py__
from sqlite3.dbapi2 import *
import datetime import time import collections.abc from _sqlite3 import * paramstyle = "qmark" threadsafety = 1 apilevel = "2.0" Date = datetime.date Time = datetime.time Timestamp = datetime.datetime def DateFromTicks(ticks): return Date(*time.localtime(ticks)[:3]) def TimeFromTicks(ticks): return Time(*time.localtime(ticks)[3:6]) def TimestampFromTicks(ticks): return Timestamp(*time.localtime(ticks)[:6]) version_info = tuple([int(x) for x in version.split(".")]) sqlite_version_info = tuple([int(x) for x in sqlite_version.split(".")]) Binary = memoryview collections.abc.Sequence.register(Row) def register_adapters_and_converters(): def adapt_date(val): return val.isoformat() def adapt_datetime(val): return val.isoformat(" ") def convert_date(val): return datetime.date(*map(int, val.split(b"-"))) def convert_timestamp(val): datepart, timepart = val.split(b" ") year, month, day = map(int, datepart.split(b"-")) timepart_full = timepart.split(b".") hours, minutes, seconds = map(int, timepart_full[0].split(b":")) if len(timepart_full) == 2: microseconds = int('{:0<6.6}'.format(timepart_full[1].decode())) else: microseconds = 0 val = datetime.datetime(year, month, day, hours, minutes, seconds, microseconds) return val register_adapter(datetime.date, adapt_date) register_adapter(datetime.datetime, adapt_datetime) register_converter("date", convert_date) register_converter("timestamp", convert_timestamp) register_adapters_and_converters() # Clean up namespace del(register_adapters_and_converters)
