      component/userhosts: use github.com/figiel/hosts for compatibility with recent libc · b1acdb0a
      Jérome Perrin authored
      In ubuntu 21.04 (libc6 2.33-0ubuntu5) or current debian testing
      (libc6 2.32-5) no longer use open to open /etc/hosts, but what appears
      as "openat" in strace output - but can not be replaced by defining an
      openat function.
      
      This uses https://github.com/figiel/hosts which uses another approach
      of replacing getaddrinfo, gethostbyname* and inet_aton.
      
      Users have been updated a bit, because there are some small differences:
       - the /etc/hosts replacement file is defined by HOSTS_FILE environment
         variable, not HOSTS
       - the library name is libuserhosts.so, not userhosts.so
      
      Other notable differences, for which we did not need code change are:
       - the new library also try to load a file when HOSTS_FILE is not set
       - the new library still use original /etc/hosts file
       - the new library supports aliases to hostnames, not only ip addresses

      software/fluentd: Fix SR test on Debian 11 · b964b95b
      Levin Zimmermann authored
      On Debian 10 the test was successful because it could use the system
      python (usr/bin/python). In Debian 11 the system python isn't available
      anymore, therefore it fails. To ensure the Fluentd program can successfully
      execute the "python custom_read_bme280.py" command, the script passes
      the same python binary to the Fluentd config file with which the test
      is called (sys.executable).

      component/python-2.7: Lib/subprocess: Speedup close_fds=True · ce75e16e
      Kirill Smelkov authored
      @romain reports that Popen(close_fds=True) is slow on py2. Let's semantically
      backport from py3 how to close only actually opened file descriptors instead of
      whole 3..`ulimit -n` range.
      
      Attached test benchmark shows the following results with `ulimit -n`=65K:
      
      Before this patch:
      
          $ ./bin/python2.7 ~/x.py
          close_fds=False:
          0.001251 s/call
          0.001337 s/call
          0.001486 s/call
      
          close_fds=True:
          0.017973 s/call
          0.018152 s/call
          0.018204 s/call
      
      After the patch:
      
          $ ./bin/python2.7 ~/x.py
          close_fds=False:
          0.001391 s/call
          0.001416 s/call
          0.001570 s/call
      
          close_fds=True:
          0.001469 s/call
          0.001479 s/call
          0.001491 s/call
      
      i.e. ~12x speedup.
      
      References on this subject are in the patch itself.
      
      The test benchmark is below:
      
      ---- 8< ----
      import timeit
      from subprocess import check_call
      
      def f():
          check_call(['true'], close_fds=False)
      def g():
          check_call(['true'], close_fds=True)
      
      N=3
      n=100
      print 'close_fds=False:'
      for i in range(N):
          print '%.6f s/call' % (timeit.timeit(f, number=n) / n)
      print
      print 'close_fds=True:'
      for i in range(N):
          print '%.6f s/call' % (timeit.timeit(g, number=n) / n)
