Buildbot如何处理多个建筑商

问题描述

我已经按照本教程在FreeBSD 12.1上设置了我的buildbot服务器：

https://www.digitalocean.com/community/tutorials/how-to-build-and-deploy-packages-for-your-freebsd-servers-using-buildbot-and-poudriere

在我更改了本教程处理工作者数组的方式之后，服务器正在使用poudriere进行构建。

我在/var/buildbot-master/master.cfg文件中针对我的情况修改了教程说明：

. . .
####### SCHEDULERS

c['schedulers'] = []

# Forceful scheduler allowed for all builders
c['schedulers'].append(schedulers.ForceScheduler(
    name='force',builderNames=[builder.name for builder in c['builders']]))

# Watch ports tree for changes on given branch
c['schedulers'].append(schedulers.SingleBranchScheduler(
    name='sched-bulk-121amd64-2020Q2',change_filter=util.ChangeFilter(project='freebsd-ports',branch='branches/2020Q2'),builderNames=['bulk-121amd64-2020Q2']))
. . .

此行在启动时给出错误：

builderNames=[builder.name for builder in c['builders']]))

我不了解pyhton，但在我看来，将所有建筑商名称放在数组中是的 ...

错误消息是：

以下部分指向我在哪里进行更改：

          File "/var/buildbot-master/master.cfg",in <module>
            builderNames=[builder.name for builder in c['builders']]))
        builtins.KeyError: 'builders'

2020-09-16 15:33:18-0300 [-] Halting master.

因此，代替检查数组，我对参数进行了硬编码：

builderNames=[builder.name for builder in c['builders']]))

收件人：

builderNames=['bulk-121amd64-2020Q2']))

然后，构建机器人将启动，并且可以运行poudriere。

我的问题是：

正确的语法应该使用什么来检查 数组c ['builders'] ，使其动态而不是硬编码？

尝试了许多来自python教程的示例，但均未成功。

解决方法

在默认的 master.cfg.sample 中，结构 c['builders'] 在 c['schedulers'] 之后创建，这就是它在您的代码中未定义的原因。

尝试在 SCHEDULERS 块之前放置（移动）BUILDERS 块。
