I've been encountering some strange issues that I have never seen before.
I'm running some a complete regression suite on an application. It's pretty
long running, in the current iteration. (over 400 seconds).
This includes a number of browser automation tasks using python and
selenium.
For anyone familiar with py.test,
I'm using a fixture to grab access to the database to make sure the logic
is working properly.
Namely:
from gluon.shell import env
from gluon.storage import Storage
@pytest.fixture()
def db():
web2py_env = env(appname, import_models=True)
web2py_env = Storage(web2py_env)
db = web2py_env.db
return db
When I use a sqlite database, I'm encountering lock issues, on a query
where there really shouldn't be lock issues.
It's a simple delete query, run before a test to ensure the appropriate
table is empty.
psuedocode:
db(db.table.id>0).delete()
driver.get(url)
When running this separately as a test, or within a group of tests, it
works fine, no lock issues.
When running this in the full regression, I'm getting database lock issues.
Then I switched to postgres for testing (I know -- cheap and dirty, but I
wanted to see if that was really the issue).
So, then I started getting even stranger errors from gluon.contrib.pg8000
namely:
NoData Object
Msg Query Idle Object
etc. etc.
In the course of testing, I've seen basically every one of the possible
pg8000 errors in the source.
Anyone have any clues as to where I might be able to track down the source?
Is it a thread issue, where I should have done from gluon import current
and then set the db in the function?
I'm wondering if this is something to do with pytest's internals or
web2py's or my own code.
Any thoughts would be greatly appreciated.
