Обсуждение: Running pgAdmin4

Hi,

I'm trying to pgAdmin4. I'm able to run pgAdmin4.py in python shell. And server runs.And able to access using browser.
Then I tried running desktop application, it throws following error,

Traceback (most recent call last):
  File "/home/prasad/Development/pgadmin4/web/pgAdmin4.py", line 73, in <module>
    app.run(port=server_port)
  File "/usr/lib/python2.7/dist-packages/flask/app.py", line 772, in run
    run_simple(host, port, self, **options)
  File "/usr/local/lib/python2.7/dist-packages/Werkzeug-0.10.1-py2.7.egg/werkzeug/serving.py", line 622, in run_simple
    reloader_type)
  File "/usr/local/lib/python2.7/dist-packages/Werkzeug-0.10.1-py2.7.egg/werkzeug/_reloader.py", line 263, in
run_with_reloader
    signal.signal(signal.SIGTERM, lambda *args: sys.exit(0))
ValueError: signal only works in main thread
Initial connection failed. Retrying in 2 seconds.
Initial connection failed. Retrying in 3 seconds.
Initial connection failed. Retrying in 4 seconds.
Initial connection failed after multiple attempts. Aborting.


I can see what error says. As Qt application spawns separate thread to run server, which apparently is not allowed.
Am I missing something ?

regards,
Prasad

I think, I did. Is there any specific settings I might have missed there ?

regards,
Prasad

Have you created config_local.py?

Ok, in that case, probably it's broken. Error mean, it doesn't like running python code in separate thread.

The desktop runtime hasn't been tested in months afaik, so it's entirely possible something is broken at the moment. It
isonly PoC code right now.

It seems , Debug mode and running server in separate thread are not compatible in Flask. And for Debug mode reloader
needto be disabled for such case. Othewise it give error. I've modified code to disable reloader in debug mode. 
This problem only affects desktop runtime.

Ok, in that case, probably it's broken. Error mean, it doesn't like running python code in separate thread.

The desktop runtime hasn't been tested in months afaik, so it's entirely possible something is broken at the moment. It
isonly PoC code right now.

Hi,

I'm trying to pgAdmin4. I'm able to run pgAdmin4.py in python shell. And server runs.And able to access using browser.
Then I tried running desktop application, it throws following error,

Traceback (most recent call last):

ValueError: signal only works in main thread

I can see what error says. As Qt application spawns separate thread to run server, which apparently is not allowed.
Am I missing something ?
Have you created config_local.py?
