Question

我实际上遇到了与post类似的问题。我的应用程序运行正常10分钟，但在这段时间过后我总是遇到这种错误：

我通过使用cron作业来调用页面。然后，此页面将启动任务队列（推送）。在这里，我试图覆盖autoflush设置，但无法达到任何改进。

import webapp2
from bdmodel import *
from indexObserver import *
import datetime
import indexObserver
from google.appengine.api.labs import taskqueue
from google.appengine.api import logservice

logservice.AUTOFLUSH_ENABLED = True
logservice.AUTOFLUSH_EVERY_SECONDS = None
logservice.AUTOFLUSH_EVERY_BYTES = None
logservice.AUTOFLUSH_EVERY_LINES = 100


class ClosingValueHandler(webapp2.RequestHandler):
    def get(self):
        self.response.write('<p>Closing Value</p>')
        taskqueue.add(url="/closing_value_queue")
        #result = detectClosingValue()
        #logging.info('detectClosingValue returned %s' % str(result))


class ClosingValueWorker(webapp2.RequestHandler):

    def post(self):
        result = detectClosingValue()
        logging.info('detectClosingValue returned %s' % str(result))

在此队列内部有一个递归方法，在到目前为止尚未达到最终状态的情况下调用自身。正如您所看到的，我已经尝试过手动清除日志但没有任何影响。有谁知道该怎么办？提前谢谢！

def detectClosingValue():
    logging.info('detectClosingValue started')
    query = "SELECT * FROM DaxValue WHERE date = DATE('%s')" % str(datetime.datetime.now().date())
    q = db.GqlQuery(query)
    daxValue = q.get()
    if not daxValue.isTradingDay:
        return False

    else:
        previous = getLatestValue()[0]
        time.sleep(5)
        i = 1

        while i < 10:
            logservice.flush()
            logging.info("retrieved close %d value at %s" % (i, str(previous)))
            if previous != getLatestValue()[0]:
                time.sleep(25)
                detectClosingValue()
            i += 1
            time.sleep(10)

        daxValue = q.get()
        daxValue.close = getLatestValue()[0]
        daxValue.high = getLatestValue()[3]
        daxValue.low = getLatestValue()[2]
        daxValue.opn = getLatestValue()[1]
        daxValue.popDate = datetime.datetime.now()
        daxValue.put()
        logging.info("stored close value at %s" % str(daxValue.close))
        return True

根据this post，当引发DeadlineExceededErrors队列中的日志时会发生错误。

如果你的应用程序运行的时间恰好是10分钟，请尝试将其运行一点点，例如9:55分钟，以便正确刷新日志。

CancelledError：API调用logservice.Flush（）被明确取消 - 如何刷新gae中的日志以防止此错误？
