instead. Add support to the runtime to allow the user to specify the
Python path. This needs to be more automated for release, but will be
useful for debugging and development.
If the web server is slow to start, we may need to retry the initial
page load. Implement a retry system that will retry the initial load
4 times, after 1, 2, 3 and 4 seconds, before giving up and leaving
the user with an error message and a link to retry manually.
Upon startup, the runtime will attempt to locate pgAdmin4.py in a
number of different relative locations. Once found, it will execute
it in a new thread. The main window is then created and the brower's
initial page is set to the root of the CherryPy server. At present,
that's http://127.0.0.1:8080.
This runtime implements a brower control with embedded Python
interpretor. The Python interpretor runs a simple script at
startup to generate some HTML that is displayed in the browser.
Arbitrary URLs can be opened from the "Open URL" option on the
File menu.
