buildbot不接受我的MailNotifier的IEMailLookup对象

Question

我们组织里有很多人的邮箱名字和他们在perforce上的名字不一样，所以我需要创建一个叫做IEmailLookup的东西，来重写getAddress这个方法，以便能满足我的需求：

（来自我的master.cfg配置文件）

class MyIEmailLookup:
    from buildbot import interfaces
    __implements__ = interfaces.IEmailLookup

    def getAddresses(user):
        address_dict = {"user1", "user_one@our_domain.com"}
        try:
            address = address_dict[user]
        except KeyError:
            address = user + "@our_domain.com"
        return address

maillookup = MyIEmailLookup()

from buildbot.status import mail

c['status'].append(mail.MailNotifier(....
                                     ....
                                     lookup=maillookup
                                    ))

我尝试了很多不同的方式，但结果要么是：

Traceback (most recent call last):
  File "/Library/Python/2.6/site-packages/buildbot-0.8.3p1-py2.6.egg/buildbot/scripts/runner.py", line 1071, in doCheckConfig
    ConfigLoader(configFileName=configFileName)
  File "/Library/Python/2.6/site-packages/buildbot-0.8.3p1-py2.6.egg/buildbot/scripts/checkconfig.py", line 46, in __init__
    self.loadConfig(configFile, check_synchronously_only=True)
  File "/Library/Python/2.6/site-packages/buildbot-0.8.3p1-py2.6.egg/buildbot/master.py", line 727, in loadConfig
    exec f in localDict
  File "/Users/playbuilder/buildbot/master.cfg", line 207, in <module>
    lookup=maillookup
  File "/Library/Python/2.6/site-packages/buildbot-0.8.3p1-py2.6.egg/buildbot/status/mail.py", line 293, in __init__
    assert interfaces.IEmailLookup.providedBy(lookup)
AssertionError

...要么是其他各种问题，这些问题取决于我怎么去实现IEmailLookup这个接口。

我现在用的是buildbot 0.8.3p1和python 2.6.1。

我发现很少有关于怎么做这个的例子，而且每一个在我的情况下都不管用。我到底漏掉了什么呢？

Answer 1

试试这个：

    from buildbot.interfaces import IEmailLookup
    from buildbot.util import ComparableMixin
    from zope.interface import implements
    class lookup_example_email(ComparableMixin):
        implements(IEmailLookup)
        def getAddress(self,user):
            return "%s@example.com"%(user)

...

mn = MailNotifier(..., lookup=lookup_example_email(), extraRecipients=m)

如果你想从Perforce用户那里获取电子邮件，可以使用这个类：

# .-----------------------.
# | Perforce Email Lookup |
# `-----------------------'

from twisted.internet import defer, utils
from buildbot.util import ComparableMixin
from buildbot.interfaces import IEmailLookup
from zope.interface import implements
import os
import re

class PerforceEmailLookup(ComparableMixin):
    implements(IEmailLookup)

    compare_attrs = ["p4port", "p4user", "p4passwd", "p4bin"]

    env_vars = ["P4CLIENT", "P4PORT", "P4PASSWD", "P4USER",
                "P4CHARSET"]

    def __init__(self,
                 p4port   = None,
                 p4user   = None,
                 p4passwd = None,
                 p4bin    = 'p4'):
        self.p4port   = p4port
        self.p4user   = p4user
        self.p4passwd = p4passwd
        self.p4bin    = p4bin
        self.email_re = re.compile(r"Email:\s+(?P<email>\S+@\S+)\s*$")

    def _get_process_output(self, args):
        env = dict([(e, os.environ.get(e)) for e in self.env_vars if os.environ.get(e)])
        d = utils.getProcessOutput(self.p4bin, args, env)
        return d

    @defer.deferredGenerator    
    def getAddress(self, name):

        if '@' in name:
            yield name
            return

        args = []
        if self.p4port:
            args.extend(['-p', self.p4port])
        if self.p4user:
            args.extend(['-u', self.p4user])
        if self.p4passwd:
            args.extend(['-P', self.p4passwd])
        args.extend(['user', '-o', name])

        wfd = defer.waitForDeferred(self._get_process_output(args))
        yield wfd
        result = wfd.getResult()

        for line in result.split('\n'):
            line = line.strip()
            if not line: continue
            m = self.email_re.match(line)
            if m:
                yield m.group('email')
                return

        yield name

使用起来大概是这样的：

c['status'].append(
    MailNotifier(
        sendToInterestedUsers   = True,
        mode                    = 'failing',
        lookup                  = PerforceEmailLookup(
                                        p4port   = "perforce:1666",
                                        p4user   = "buildbot",
                                        p4passwd = "buildbot")))

Answer 3

我刚刚自己解决了这个问题。

首先，你需要在文件的顶部添加一些内容：

from zope.interface import implements

然后把

__implements__ = interfaces.IEmailLookup

改成

if implements:
    implements( interfaces.IEmailLookup )
else:
    __implements__ = interfaces.IEmailLookup
