P4Python不能使用进度类

Question

我不知道这为什么会引起AttributeError，但在文件中，这似乎是正确的https://www.perforce.com/manuals/p4python/Content/P4Python/python.p4_progress.html

from P4 import P4, P4Exception, Progress
from tqdm import tqdm


class P4ProgressHandler(Progress):
    TYPES = ["Unknown", "Submit", "Sync", "Clone"]
    pbar = None

    def init(self, type):
        super().init(type)
        if self.pbar is not None:
            self.pbar.close()
        self.pbar = tqdm(desc="P4 Progress: {}".format(self.TYPES[type]))

    def setDescription(self, description, units):
        super().setDescription(description, units)

    def setTotal(self, total):
        super().setTotal(total)
        self.pbar.total = total

    def update(self, position):
        super().update(position)
        if self.pbar is not None:
            self.pbar.update(position)

    def done(self, fail):
        super().done(fail)
        if self.pbar is not None:
            self.pbar.close()
p4 = P4()
p4.using_progress(P4ProgressHandler()) 

Python版本: 3.10.0

P4Python版本: P4PYTHON/"NTX64"/"2022.1"/"2299330“("2022.1/2285021”API) ("2022"/"06"/"14")。

错误输出：

Traceback (most recent call last):
  File "E:\ForgeCI\ForgeCI\Utils\P4Methods.py", line 37, in <module>
    p4.using_progress(P4ProgressHandler())
  File "E:\ForgeCI\venv\lib\site-packages\P4.py", line 517, in __getattr__
    raise AttributeError(name)
AttributeError: using_progress

根据P4类的文档，没有using_progress方法：

https://www.perforce.com/manuals/p4python/Content/P4Python/python.p4.html#Instance_Methods_..39

在此与AttributeError之间，我认为可以安全地假定，文档中提到Progress类的P4.using_progress是文档中的一个错误。由于progress是P4的一个属性，所以您应该能够替换：

p4.using_progress(P4ProgressHandler()) 

通过以下方式：

p4.progress = P4ProgressHandler()
