python - P4Python p4.temp_client 坏了？

Question

我似乎无法将临时客户端与 p4python 一起使用...

当我保存客户端时，我可以很好地同步。 例如。

from P4 import P4,P4Exception
p4 = P4()
p4.client = "example"
p4.port = "1666"
p4.user = "fooser"
client_root = '/foo/bar'

p4.connect()
client = p4.fetch_client()
client._root = client_root
p4.save_client(p4)
p4.run_sync('-f')

工作正常。我在我的仓库中获取文件。

但是，如果我将最后一行调整为临时客户端...

with p4.temp_client('temp',client) as t:
    p4.run_sync()

我收到以下错误...

我试图深入研究一下源代码，但这个库似乎依赖于一个 c++ 模块，我无法深入了解那里。

查看错误我可以看到它试图将 Python dict 的字符串表示形式作为“-t”标志传递给 p4 命令，这显然是错误的。 :)

来自 temp_client 上的文档:

p4.temp_client( "<prefix>", "<template>" ) Creates a temporary client, using the prefix <prefix> and based upon a client template named <template>

第二个参数只是模板客户端的名称(作为字符串)，而不是整个规范(作为字典)。这就是将作为 -t template 传递的内容在实际的 p4 命令中。

尝试:

with p4.temp_client('temp', 'example') as t:
    p4.run_sync()
