[gentoo-user] Problem executing pgAdmin4

[gentoo-user] Problem executing pgAdmin4

[Petric Frank]

Hello,

pgadmin3 is masked now. So i installed pgadmin4 (current stable verion 3.0). 
Installed w/o problems.

But when executing it (in a terminal window) i get a dialog box saying
  An error occurred initialising the application server:
  An error occurred initialising the application server:
  %1

and the terminal window is filled pagewise with
----------------------- cut ---------------------------
Python path:  "/usr/lib64/python3.6/site-packages" 
Python Home:  ""
Webapp path:  "/usr/share/pgadmin4/web/pgAdmin4.py"

Selecting "Ok " in the dialog box i get an other tabbed dialog box asking for 
a browser command (currently empty) and Python paths (preset values seem ok).

Entering "/usr/bin/firefox %URL%" as browser command does not change anything.

Any hints ?

Info:
  Kernel 4.14.65 (Gentoo)
  KDE Plasma (kde-plasma/plasma-meta-5.13.5)
  Memory 16 G
  Apache installed but not running
  Browsers konqueror and firefox available
  pgadmin3 still installed
  Python 2.7, 3.6 and 3.5 installed (= "eselect python list" output)

Interesting.  I only get
-------------
Python path:  "/usr/lib64/python3.6/site-packages"
Python Home:  ""
Webapp path:  "/usr/share/pgadmin4/web/pgAdmin4.py"
------------
And then a popup that says  "The application server could not be  
contacted."

This is with eselect postgresql set to either 9.6 or 10.  Also - all  
above running as myself, although I get the same results with root or  
postgres.  It looks like although I have 10 installed, I never  
initialized it, although 9.6 should work OK.

I'm now emerging the test version of pgAdmin4 to see if it makes any  
difference.

Hello Jack,

if i remove the .pgadmin directory in my home i get - after a long wait a 
dialog box saying 
 The application server could not be contacted.

In the terminal it prints:
-------------------------- cut ------------------------------
Python path:  "/usr/lib64/python3.6/site-packages" 
Python Home:  ""
Webapp path:  "/usr/share/pgadmin4/web/pgAdmin4.py"
NOTE: Configuring authentication for DESKTOP mode.
-------------------------- cut ------------------------------

Starting pgAdmin4 again i get the output and dialogs i wrote initially in this 
thread.

regards
  Petric

I installed pgadmin4-3.4-r1 and it works.  3.5 has been released  
(https://www.pgadmin.org/) so I filed a version bump request  
(https://bugs.gentoo.org/670556).

I will try the upgrade.

For documentation purposes i got version 3.0 running using this guide:

1. install dev-python/backports and dev-python/backports-csv (masked !)
2. extend file /usr/share/pgadmin4/web/config_local.py to contain:
    import os
    DATA_DIR = os.path.realpath(os.path.expanduser(u'~/.pgadmin/'))
    LOG_FILE = os.path.join(DATA_DIR, 'pgadmin4.log')
    SQLITE_PATH = os.path.join(DATA_DIR, 'pgadmin4.db')
    SESSION_DB_PATH = os.path.join(DATA_DIR, 'sessions')
    STORAGE_DIR = os.path.join(DATA_DIR, 'storage')
    SERVER_MODE = False
    UPGRADE_CHECK_ENABLED = False

3. start python /usr/share/pgadmin4/web/pgAdmin4.py
4. point your browser to localhost:5050

Hope that helps someone ...

That seems like a lot of effort, unless you really don't want to emerge  
a testing version of a package.  There is now an ebuild (testing) in  
the tree for 3.5, and it also requires a testing version of  
dev-python/psutil.  It looks like some version incompatability snuck in  
with some upgrade of either pgAdmin4 or python.  I wonder if selecting  
a different version of python would work?

3.5 uses localhost:40429, although I suppose that is configurable.  In  
addition, I really had to hunt to figure out how to stop the program.   
Just closing the web browser does not stop the pgAdmin4 server process  
- to close that you have to find it in the system tray, and shut it  
down from there.
