P4Python p4.temp_client坏了？

Question

我似乎不能在p4python中使用临时客户端...

当我保存一个客户端时，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。我在仓库里拿到了文件。

但是，如果我将最后一行修改为临时客户端...

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

我得到了下面的错误...

我试着深入研究了一下源码，但是这个库似乎依赖于c++模块，我已经超出了我的能力范围。

查看错误，我可以看到它试图将Python dict的字符串表示作为"-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arg只是模板客户端的名称(作为字符串)，而不是整个规范(作为dict)。这就是在实际的p4命令中作为-t template传递的内容。

尝试：

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