Sco*_*tes 7 python django celery urllib3 python-requests
我正在尝试诊断一个问题,我的一些芹菜工人进程似乎挂了几分钟.我有许多任务可以进行多次IO调用(通常是第三方API).在任何给定的工作中,我可能会对各种API提出数千个请求.我查看了日志,它们都有共同点:它们在urllib3连接到远程URL 后挂起.
在我的工作结束时(大约需要30分钟),通常会挂起一些任务.
以下是我用来推断的日志的例子urllib3:罪魁祸首:
Jul 08 04:46:26 app/worker.1: [INFO/MainProcess] [???(???)] celery.worker.strategy: Received task: my_celery_task[734a49f6-bf6b-4423-9146-1c48366ba897]
Jul 08 04:46:28 app/worker.1: [DEBUG/Worker-11] [my_celery_task(734a49f6-bf6b-4423-9146-1c48366ba897)] src.aggregates.prospect.services.prospect_service: Beginning: Get social account data. provider_name: twitter, account_uid: some_user
Jul 08 04:46:28 app/worker.1: [INFO/Worker-11] [my_celery_task(734a49f6-bf6b-4423-9146-1c48366ba897)] requests.packages.urllib3.connectionpool: Starting new HTTPS connection (1): api.some_api.com
然后就是这样.Starting new HTTPS connection声明后没有任何记录.
这是我重新启动worker的地方:
Jul 08 05:09:18 app/worker.1: [INFO/MainProcess] [???(???)] celery.worker.strategy: Received task: my_celery_task[734a49f6-bf6b-4423-9146-1c48366ba897]
Jul 08 05:09:19 app/worker.1: [DEBUG/Worker-4] [my_celery_task(734a49f6-bf6b-4423-9146-1c48366ba897)] src.aggregates.prospect.services.prospect_service: Beginning: Get social account data. provider_name: twitter, account_uid: some_user
Jul 08 05:09:19 app/worker.1: [DEBUG/Worker-4] [my_celery_task(734a49f6-bf6b-4423-9146-1c48366ba897)] requests.packages.urllib3.connectionpool: "GET /v2/api_call.json?username=some_user HTTP/1.1" 403 170
Jul 08 05:09:19 app/worker.1: [INFO/Worker-4] [my_celery_task(734a49f6-bf6b-4423-9146-1c48366ba897)] requests.packages.urllib3.connectionpool: Starting new HTTPS connection (1): api.some_api.com
Jul 08 05:09:19 app/worker.1: [INFO/MainProcess] [???(???)] celery.worker.job: Task my_celery_task[734a49f6-bf6b-4423-9146-1c48366ba897] succeeded in 2.265356543008238s: 32345
在这种情况下,我收到了403状态代码.所以这可能是一个潜在的罪魁祸首.但是,我在日志中看到,这也发生了状态代码200.
FWIW,我也Resetting dropped connection: api.twitter.com经常在日志中看到.
我已确保在timeout使用该requests库提出请求的任何地方提供10秒钟.
因此看起来请求已经完成,但随后就会挂起.远程服务器可能以非常慢的速度响应,因此超时从未实际发生,但我发现这不太可能,因为我的问题不会发生在一个特定的域中.
我正在使用Rabbit 3.1.3 celery:3.1.11(Cipater)kombu:3.0.16 py:3.4.0 billiard:3.3.0.17 py-amqp:1.4.5.我正在使用prefork.
我正在使用请求== 2.3.0.
那么为什么在urllib3记录Starting new HTTPS connection语句后我的任务会挂起呢？
编辑:我添加了大量的日志记录,并在下面提供了进一步的上下文

根据我的日志声明,罪魁祸首是load_verify_locations.
这是requests库中的相应代码:
if ca_certs:
try:
context.load_verify_locations(ca_certs)
# Py32 raises IOError
# Py33 raises FileNotFoundError
except Exception as e: # Reraise as SSLError
raise SSLError(e)
所以它似乎context.load_verify_locations(ca_certs)导致它挂起.为什么？
您正在使用该multiprocessing.dummy模块吗？即线程池？
from或的Pool模块中似乎存在一个错误，这似乎会导致随机 HTTP 连接在建立后（即 TCP SYN-ACK 周期完成后）挂起。multiprocessing.dummyurllib3
发生此错误的一个迹象是，当您使用 Wireshark 跟踪 TCP 请求/响应时，您会看到已成功建立 TCP 连接，然后在几分钟后出现 TCP RST，并且其间没有应用程序协议流量。
您可能想尝试将多处理池代码切换为基于进程，即使用多处理而不是 multiprocessing.dummy。
即代替
from multiprocessing.dummy import Pool as ThreadPool
使用
from multiprocessing import Pool as ProcessPool
上面的方法对我有用，错误就消失了。
