如何使buildbot通過特定事件運行任務？

Question

有什么方法可以配置master.cfg，以計划生成器在修改項目文件夾或文件（或更改其FileVersionInfo）時執行該代碼？

我知道這是一個解決方法，但是我需要它來在開發人員編譯產品的較新版本后立即運行構建驗證測試，並且由於許多項目的開發不在CVS中進行，因此我需要使用掃描儀項目文件夾。

以下是master.cfg的摘錄：

def create_builders_and_schedule_it(factory, build_slaves, **kwargs):
    # kwargs: change_filter=None, nightly=None, trigger_name=None)

    builder_names = []

    if hasattr(factory, 'subcategory'):
        cat = "%s_%s" % (factory.category, factory.subcategory)
    else:
        cat = factory.category

    if 'change_filter' in kwargs:
        change_filter = kwargs['change_filter']
    else:
        change_filter = filter.ChangeFilter( branch = factory.branch )

    for i_slave in build_slaves:
        builder_name = "%s_%s" % (cat, i_slave)
        builder_names.append(builder_name)
    c['builders'].append(
        BuilderConfig(name = builder_name,
                      category = factory.category,
                      factory = factory,
                      slavename = i_slave
                ))

    # every task has 'forced' scheduler at least
    c['schedulers'].append(
        ForceScheduler(name = cat + "_force",
                       builderNames = builder_names))

    # every task has 'on commit' scheduler
    c['schedulers'].append(
        SingleBranchScheduler(name = cat + "_singlebranch",
                       builderNames = builder_names,
                       change_filter = change_filter))

    # some task can be scheduled
    if 'nightly' in kwargs:
        c['schedulers'].append( timed.Nightly(
                                name = cat + '_nightly',
                                branch = factory.branch,
                                builderNames = builder_names,
                                hour = kwargs['nightly'][0], minute = kwargs['nightly'][1]))                                

    if 'trigger_name' in kwargs:
        c['schedulers'].append(
            Triggerable(
                name = kwargs['trigger_name'],
                builderNames = builder_names))

有一個從BuildFactory派生的典型類：

class Autotests(BuildFactory):
    """ Build products from Autotests repository """
    def __init__(self, branch):
        BuildFactory.__init__(self)
        self.category = "autotests"
        self.branch = branch
        self.addStep(
            Git(repourl = AUTOTESTS_REPO, branch = branch))

    def build_source_archive(self):
        self.subcategory = "source"
        self.addStep(
            ShellCommand(
                workdir = "build",
                command = ["./upload_to_binary_repo.sh"]))
        return self

    def run_BVT_prod(self):
        self.subcategory = "BVT_prod"
        self.addStep(
            ShellCommand(
                workdir = "build/BVT_tests/prod",
                env = {'PATH':"/usr/bin:/bin", 'VIRTUAL_ENV':''},
                command = ["./bvt_runner.sh"] ))
        return self

現在有了方法和類，我們

create_builders_and_schedule_it(
    Autotests("devel").run_BVT_Prod(),
    ['VIX_runner'],
    nightly = (2,0)
)

有執行這種檢查的常用方法嗎？ 還是我應該朝另一個方向看？

您可以在以下行上使用FileExists的自定義版本：

from buildbot.steps.slave import FileExists
class CustomFileExists(FileExists):
    # By default false
    output_files_exist = False

    def __init__(self, file, **kwargs):
        CustomFileExists.output_files_exist = False
        FileExists.__init__(self, file, **kwargs)

    # Override the commandComplete
    def commandComplete(self, cmd):
        if not cmd.didFail():
            # for e.g. check the last modification time on the file
            # or do your own cooking to check whether to proceed or not !!
            s = cmd.updates["stat"][-1]
            if s[stat.ST_MTIME] > s[stat.ST_CTIME]:
                # If it satisfies your condition, then set it to True
                CustomFileExists.output_files_exist = True
        self.finished(SUCCESS)
        return

從名稱看來，它似乎只是檢查文件，但是您可以對文件執行任何操作，例如，使用stat命令。

在此構建器的主要構建配置中，您需要在執行測試之前添加一個新步驟。 就像是：

project_file = r'path\to\the\built\product\image'
factory.addStep(CustomFileExists(project_file))

如果找不到該文件（或不滿足您的約束），它將在此停止並不會執行測試。

重要的是要注意，此步驟將在從屬設備上執行，這意味着將在從屬設備而不是主設備上檢查文件。

我希望這可以幫助你。
