Hello, ALL. I m trying to make kindo progress bar on app engine and
with clientside JsUpload lib.
(below it is all about on production, not on local dev, cause of it is
not supporting simult reqeusts, thats pitty yoo)
When parsing post request with file uploading multipart encoded data
(POST method), i'm setting some "progress_key" in memcache, and
concurrently ajax lib is asking for this progress by get() request
(GET method) multiple times (until the progress value 'done' will be
eq to 'total'), and method it calls must return this "progress_key"
from memcache.
It is very wierd, i do see my post() method setting this key during
request body reading, but ajax call gets always None from memcache.
And when post() is finished (i see it in logs), ajax get() call
suddenly gets the right value
progress_key is absolutely the same for get() and post() handlers,
actually, it is the same handler, and self.sid which is used for
creating progress_key is gitten from cookie, i checked the logs, key
is really the same
what can be wrong here? where is the error?
def updateProgress(self, done,total): # during post()
log("UPDATING PROGRESS:"+str("%i/%i" % (done,total)))
key = "PROGRESS_"+self.sid
log("KEY:"+key)
memcache.set(key,(done,total))
log("UPDATED"+str(memcache.get(key)))
def getProcess(self): # during get()
key = "PROGRESS_"+self.sid
progress = memcache.get(key)
if not progress:
progress = (0,0)
(done,total) = progress
...
self.response.out.write("%i %i" % (done,total))
