如何讓buildbot通過某些事件來運行任務？

Question

有沒有什麼辦法可以配置master.cfg來安排構建器在其中的項目文件夾或文件被修改（或其FileVersionInfo已更改）時執行代碼？

我知道這是一個很好的解決方法，但是我需要這個在開發人員編譯產品的新版本後立即運行構建驗證測試，並且由於一些項目的開發不在CVS中，所以我需要項目文件夾的掃描儀。

下面是Master.cfg中提取物：

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)) 

有來自BuildFactory派生一個典型的類：

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 

現在我們有方法和類，我們

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

有沒有一種常見的方法來執行這種檢查？或者我應該朝另一個方向看？

您可以使用FileExists定製版的東西在下面幾行：

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 

從現在看來，這只是檢查文件的名字，但你可以做任何與文件，例如與stat命令。

在您爲此構建器構建的主要配置中，您需要在執行測試之前添加一個新步驟。例如：

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

如果找不到文件（或不符合您的約束條件），它將停止在那裏，測試將不會執行。

重要的是要注意，這一步將在從站上執行，這意味着文件將在從站而不是在主站上進行檢查。

我希望這可以幫助你。
