Hi Anand,
I see that no one has put our dbase bug-fix into http.background().
It's a pretty bad bug causing random dbase corruption. See below
Thanks,
Berwyn
def background(func):
"""A function decorator to run a long-running function as a
background thread.
+ GOTCHA: Until the foreground task ends, any db access by
background task
+ will necessarily get old data from before the foreground task
started
+ because psycopg2 begins a transaction in the foreground task
until it quits """
def internal(*a, **kw):
web.data() # cache it
tmpctx = web._context[threading.currentThread()]
web._context[threading.currentThread()] =
utils.storage(web.ctx.copy())
def newfunc():
web._context[threading.currentThread()] = tmpctx
+ # Create new db cursor if there is one else background thread
+ # overwrites foreground cursor causing rubbish data into dbase
+ if web.config.get('db_parameters'):
+ webdb.connect(**web.config.db_parameters)
func(*a, **kw)
