I have this code
import threading
import os
import py7zr
from py7zr import FILTER_LZMA2, FILTER_CRYPTO_AES256_SHA256, FILTER_DELTA, PRESET_DEFAULT
class My_Thread(threading.Thread):
`` def init(self, name, Archive, CheminSource, Root, Label, Objet):

`` `` self.Label = Label
`` `` self.Objet = Objet
`` def run(self):

def ZipArchiveAtome(Archive, CheminSource, Root, Label, Objet):
`` TbleTemp = CheminSource.split("\")

`` if (TbleTemp[lgCheminSource - 1] == ""):
`` `` lgCheminSource = lgCheminSource - 1

`` lgRoot = len(TbleTemp)
`` if (TbleTemp[lgRoot - 1] == ""):

filter = [{'id': FILTER_DELTA}, {'id': FILTER_LZMA2, 'preset': PRESET_DEFAULT}]
Target = r'D:\Test-7z-01.7z'
CheminSource = r'D:\Test'

TbleThreads = []
MaxThreads = 16
with py7zr.SevenZipFile(Target, mode='w', filters=filter, blocksize=10485760) as Archive:

and when I run it, I have this error :
Exception in thread Test-03.py:
Traceback (most recent call last):
File "A:\01) - System\Python\Python - 3.10\lib\threading.py", line 1016, in _bootstrap_inner

Test I have done :
When I bypass the multithreading, it's OK.
when I use the multithreading but in the "run" def I call my def it's ok like
def run(self): Test(self.Archive, self.CheminSource, self.Root, self.Label, self.Objet)
def Test(Archive, CheminSource, Root, Label, Objet): print("Chemin Source : ", CheminSource) print("Root : ", Root)
i wonder if the multithreading and py7zr are compatible.
Questions :
-
- Is my code correct ?
-
- Is py7zr compatible with the multithreading when you want to create the archive ?
Thanks in advance for your answers.
