[GitHub] [pulsar] zbentley opened a new issue #14582: C++/Python pulsar client abort()s or segfaults on file descriptor exhaustion ("Too many open files")

[GitBox <gi...@apache.org>]

zbentley opened a new issue #14582:
URL: https://github.com/apache/pulsar/issues/14582


   **Describe the bug**
   When the C++ pulsar client tries to open a file descriptor, (e.g. creating a client, creating a producer, or creating a consumer), this operation can fail if the environment has too many open files.
   
   When that failure occurs, `abort()` is sometimes called, or SIGSEGV sometimes occurs. *Both* of these behaviors shouldn't happen; an exception should be raised instead. 
   
   **To Reproduce**
   1. Set your `ulimit` very low, e.g. 10.
   2. Create a Python pulsar-client object.
   3. Create consumer objects in a loop.
   
   This sample code can help reproduce the issue.
   
   ```python
   import logging
   import resource
   import pulsar
   
   def main():
       resource.setrlimit(resource.RLIMIT_NOFILE, (5, 5))
       client = pulsar.Client(service_url='pulsar://localhost', logger=logging.getLogger())
       client.subscribe(topic='mytopic', subscription_name=f'mysub')
   
   if __name__ == '__main__':
       main()
   ```
   
   **Expected behavior**
   A clear and concise description of what you expected to happen.
   
   **Example exception**
   
   There are two failure modes:
   
   1. A segfault.
   2. An error stack like this:
   
   ```
    libc++abi: terminating with uncaught exception of type boost::wrapexcept<boost::system::system_error>: pipe_select_interrupter: Too many open files
   Fatal Python error: Aborted
   ```
   
   **Environment:**
    - OS: MacOS monterey.
    - Client version: 2.9.1
