  Python & Visual Studio code 

  The official python plugin claims that the interpreters of Pipenv are automatically found.

  They are not.

  At least not on my machine.

  Here’s how you set them.

  JIRA and Python 

  I really came to hating JIRA with a passion. And now I have to create about 350 tickets.

  Naturally I don’t do this by hand. But using the JIRA API is kind of … hard, there is a Python library, but usage is rather sparsely documented, and this whole thing is just annoying as hell.

  Although when you did it, it’s quite simple. Here’s an example of how to create a ticket with due date and estimate set from a CSV file:

  create a JIRA issue using Python and the JIRA module

  Python

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

  from pprint import pprint, pformat from getpass import getpass   import jira def do_shit():     url = read("JIRA url:")     username = read("JIRA username:")     password = getpass("JIRA password:")     jira_inst = jira.JIRA(url, basic_auth=(username, password))     test = {         "project":          {"key": "TEST"},         "issuetype":        {"name": "Task"},         "labels":           ["deleteme", "whatisthis"],         "summary":          "woho",         "description":      "wohooooo",         "duedate":          "2017-11-11",         "timetracking":    {"originalEstimate": "4d"},     }     created = jira_inst.create_issues([test])     pprint(created) if __name__ == "__main__":     do_shit()

  So simple.

    Hi Axel, hast Du auch einen Twitter Account, in dem Du über neue Updates aus Deinem Blog informierst, oder ist der RSS Feed meine (einzige?) Anlaufstelle?

      Hey Mika, gute Idee eigentlich 🙂 . Aktuell ist es nur RSS. Ich könnte allerdings einen Twitter-Feed dafür einrichten … .
      Freut mich allerdings dass du auf dem Laufenden bleiben möchtest 😀 . Und sorry wegen der langen Antwortzeit – ich war 4 Wochen im Urlaub. Dringend notwendig.

  PyCharm, Arch linux & Python 3.6 

  Love Python. Love PyCharm. Love Arch Linux.

  Unfortunately Arch sneakily updated Python to 3.6. Cool, new version … but hey, why don’t my debug runs in PyCharm work any more??

  1	ImportError: libpython3.5m.so.1.0: cannot open shared object file: No such file or directory

  Yup, pretty confusing. It seems unable to find shared python 3.5 library. Well. After some cursing, turns out the solution is pretty simple (if you know what to do):

  • get pyenv
  • use pyenv to install Python 3.5.2, but with –enable-shared option set
  • use this python version for PyCharm projects (it does not matter if it’s in a virtualenv or not)

  Like this:

  1 2 3 4 5

  $ PYTHON_CONFIGURE_OPTS="--enable-shared" pyenv install 3.5.2 [...] $ sudo $HOME/.pyenv/versions/3.5.2/bin/python "/opt/pycharm-professional/helpers/pydev/setup_cython.py" build_ext --inplace [...] $ _

  That solved it for me 🙂

  Really annoying thread properties 

  This sucks monkey ass, mainly because I didn’t think of that before. And that’s just one example why multi-threaded (soon to be -processing, probably) applications are hard.

  [code]import subprocess as sp
  import time
  import os
  from threading import Thread

  class MyThread(Thread):

  def __init__(self, mydir):
  super().__init__()
  self.mydir = mydir

  def run(self):
  os.chdir(self.mydir)
  time.sleep(2)
  print("I’m (%s) in directory %s"
  % (str(self), os.getcwd()))

  if __name__ == "__main__":
  MyThread("/tmp").start()
  time.sleep(1)
  MyThread("/").start()
  [/code]

  Result is:

  [code]I’m (<MyThread(Thread-1, started 140195858716416)>) in directory /
  I’m (<MyThread(Thread-2, started 140195850323712)>) in directory /[/code]

  OpenStack floating IP convenience 

  Problem: I am working in a tenant which has a couple of hosts with floating IPs assigned. I always have to look them up either manually using the command line clients (and dealing with all those UUIDs), or manually in the web GUI. Didn’t like.

  Solution: Python script, which outputs FLOATING_IP -> HOST_NAME.

  Here it is.

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52

  #!/usr/bin/env python   from novaclient import client import novaclient.v2.floating_ips as os_fips import novaclient.v2.servers as os_servers import novaclient.v2.networks as os_networks   #from pprint import pprint as pp import os from sys import exit     def error(printme):     print("ERROR: {}".format(printme))     exit(-1)   def check_env():     for a in ("OS_TENANT_ID", "OS_TENANT_NAME", "OS_AUTH_URL", "OS_USERNAME", "OS_PASSWORD"):         if not os.environ.get(a): error("Please set ${}".format(a))   def get_client():     check_env()     return client.Client(2,                          os.environ["OS_USERNAME"],                          os.environ["OS_PASSWORD"],                          os.environ["OS_TENANT_NAME"],                          os.environ["OS_AUTH_URL"])     if __name__=="__main__":     nova = get_client()     fipman = os_fips.FloatingIPManager(nova)     servman = os_servers.ServerManager(nova)     netman = os_networks.NetworkManager(nova)       ips = fipman.list()     srs = servman.list()       id2server = {}     for a in srs:         id2server[a.id] = a       ips = [(ip.ip, ip.instance_id) for ip in ips]     # filter out unused floating ips (which have  as instance id)     ips = filter(lambda x: x[1], ips)     # create (IP, SERVER_NAME pairs)     ips = map(lambda x: (x[0], id2server[x[1]].name), ips)     # sort for convenience by host instance name     ips = sorted(ips, key=lambda x: x[1].lower())       for a in ips:         print("{:18s} {}".format(a[0], a[1]))

  Sample output:

  1 2 3 4 5 6 7 8

  $ tools/list_ips 10.64.108.163      ab_1695_1_dml 10.64.108.199      ab_1695_1_jump 10.64.108.160      media0 10.64.109.97       RJD1_CouchbaseA1 10.64.109.99       RJD1_JumpServer 10.64.109.98       RJD1_OpenshiftMaster 10.64.109.148      tla-centos66

  Groovy.
