Re: [twitter-dev] Re: xauth error -1012
Yes, a...@twitter.com granted my app for xAuth... Any suggestion on what I should do to fix the issue? I did all I can and I'm STUCK at the point. A little easy googling (for NSURLErrorDomain error 1012) turned up http://stackoverflow.com/questions/501231/can-i-use-nsurlcredentialstorage-for-http-basic-authentication, which might be helpful for you. Also, again, some very easy searching in the Xcode docs yields NSURLErrorDomain error -1012 as: NSURLErrorUserCancelledAuthentication Returned when an asynchronous request for authentication is cancelled by the user. This is typically incurred by clicking a “Cancel” button in a username/password dialog, rather than the user making an attempt to authenticate. So it looks like you're getting an auth request in the http response and you're not handling it correctly / at all. So either the auth request is incorrect -- in which case you should probably post the full http request and response to this list -- or you need to handle it. (If you don't know how to handle it, and you can't figure it out from the docs, it's probably a question better suited for an iPhone dev list.) -josh On Apr 20, 1:27 pm, Taylor Singletary taylorsinglet...@twitter.com wrote: Hi Sae, Have you received approval for using xAuth in your application yet by emailing a...@twitter.com ?

Re: [twitter-dev] Problem with JSON
It looks like you are implicitly assuming that the OS will send you
chunks of stream data that correspond to single, complete parsable
chunks. That may have worked accidentally because that happened to be
how they arrived in time, but it is definitely unreliable (as you
found). What you should do in connection:didReceiveData: is buffer the
data you received, and split it up yourself by looking for the
delimiters that separate individual tweets, and then parse those
individual tweets.

[twitter-dev] Any chance of annotations for user objects?
I know you guys have plenty on your plates, just curious if it was on the roadmap. :) Sample use case (one I particularly want): Tweetie on my phone and Tweetie on my laptop could easily stay synced about where in my tweet stream I have read to. Other features like saved searches and lists could easily have begun life as user annotations. Generally lots of client data (prefs, settings, state) could be stored where it belongs, in the cloud, making it less transient, easier to migrate/sync/import/share, etc. Really excited about annotations -- thanks!

Re: [twitter-dev] Re: Upcoming changes to the way status IDs are sequenced
Hi John (et al.), These emails from you are great -- they are exactly the sort of thoughtful, detailed, specific, technical emails that I would personally love to see accompany future announcements. I think they would prevent a fair amount of FUD. Thank you. I have one stupid question, if you don't mind, though. You refer in every email to K. What, precisely, does K refer to? What are its units? (I think I know what it you mean by it, but I'd be interested to hear precisely.) Thanks, Josh On Sun, Apr 11, 2010 at 2:23 PM, John Kalucki j...@twitter.com wrote: If you are writing a general purpose display app, I think, (but I am not at all certain), that you can ignore this issue. Reasonable polling frequency on modest velocity timelines will sometimes, but very rarely, miss a tweet. Also, over time, we're doing things to make this better for everyone. Many of our projects have the side-effect of reducing K, decreasing the already low since_id failure odds even further. Some tweet pipeline changes when live in the last few weeks that dramatically reduce the K distribution for various user types. Since I don't know how the Last-Modified time exactly works, I'm going to restate your response slightly: Assuming synchronized clocks (or solely the Twitter Clock, if exposed properly via Last-Modified), given a poll at time t, the newest status is at least t - n seconds old, and sufficient n, then even a naive since_id algorithm will be effectively Exactly Once. Assuming that Twitter is running normally. For a given poll, when the poll time and last update time delta drops below this n second period, there's a non-zero loss risk. Just what is n? It is K expressed as time rather than as a discrete count. For some timelines types, with some classes of users, K is as much as perhaps 180 seconds. For others, K is less than 1 second. There's some variability here that we should characterize more carefully internally and then discuss publicly. I suspect there's a lot to be learned from this exercise. Since_id really runs into trouble when any of the following are too great: the polling frequency, the updating frequency, the roughly-sorted K value. If you are polling often to reduce display latency, use the Streaming API. If the timeline moves too fast to capture it all exactly, you should reconsider your requirements or get a Commercial Data License for the Streaming API. Does the user really need to see every Bieber at 3 Biebers Per Second? How would they ever know if they missed 10^-5 of them in a blur? If you need them all for analysis, consider calculating the confidence interval given a sample proportion of 1 - 10^6 (6 9s) or so vs. a total enumeration. Indistinguishable. If you need them for some other purpose, say CRM, the Streaming API may be the answer. -John Kalucki http://twitter.com/jkalucki Infrastructure, Twitter Inc.

The period between your next poll and the timestamp of the last status is irrelevant. The issue is solely the magnitude of K on the roughly sorted stream of events that are applied to the materialized timeline vector. As K varies, so do the odds, however infinitesimally small, that you will miss a tweet using the last status id returned. The period between your polls of the API does not affect this K. My recommendation is to ignore this issue in nearly every use case.

Re: [twitter-dev] Re: Upcoming changes to the way status IDs are sequenced
So I think we need to allow Twitter some leeway here. I apologize if my tone came off badly; it was not intended. I've just had bumpy rides using timestamps for coordination in distributed systems (less cool ones than space flight), so this worried me a little. In the end, whatever Twitter decides to do, I'll work with. As far as occasional glitches are concerned, we have those now. Every so often, we still get Fail Whales, 5xx errors, DDos attacks, etc. The difference is that those errors are straightforwardly detectable on the client side and can be handled more or less gracefully. Minor, intermittent data issues (like the odd missing tweet) are less straightforward to detect, but still trigger support emails. :) -josh To unsubscribe from this group, send email to twitter-development-talk+unsubscribegooglegroups.com or reply to this email with the words REMOVE ME as the subject.
Re: [twitter-dev] Re: Upcoming changes to the way status IDs are sequenced
Hi Taylor (et al.), There are two reasons to think that, with the scheme you propose, tweet ids will not necessarily be monotonically increasing. Naveen hit the first: It seems if two messages are posted at very close to same time, they may not be sequential since the bottom bits will be randomly generated There is another: Time synchronization is hard to always get right (Einstein jokes aside). Clock skew happens for any number of reasons -- sometimes ntpd sends time backwards when network i/o gets really ugly, machine clocks wander, colos get out of sync, humans err, etc. These are rare events, but they do happen, and they can cause misalignment of clocks big enough for the odd tweet or two to fall through. Does missing the odd tweet or two matter? As for the tweet themselves: Probably not. But if it gets noticed, it causes users / developers to lose some amount of trust in their app / platform...and that matters a lot and can also generate a lot of annoying support emails. You wrote: since_id will work as well as it does today as a result of this change. Is that assuming monotonically increasing tweet ids? If not, would you mind elaborating? Having a universal counter is untenable, but having occasional, undiagnosable, unreproducible glitches also sucks. :) Thinking out loud, perhaps there is some middle ground -- a way to have generally monotonically increasing ids globally, and guaranteed monotonically increasing ids along some useful dimension, such as per user (this doesn't play nicely e.g. w/ Cassandra, but it is still reasonably scalable by other means). Not sure whether that would help folks or not... -josh To unsubscribe from this group, send email to twitter-development-talk+unsubscribegooglegroups.com or reply to this email with the words REMOVE ME as the subject.

[twitter-dev] Oauth using api.twitter.com vs twitter.com
Hi all, The tweepy twitter client uses api.twitter.com for the host for oauth calls: REQUEST_TOKEN_URL = 'http://api.twitter.com/oauth/request_token' AUTHORIZATION_URL = 'http://api.twitter.com/oauth/authorize' AUTHENTICATE_URL = 'http://api.twitter.com/oauth/authenticate' ACCESS_TOKEN_URL = 'http://api.twitter.com/oauth/access_token' I've found that this works, until the user tries to sign out or sign up during the authorization; if this happens, they get a 404. If, however, twitter.com is used as the host: REQUEST_TOKEN_URL = 'http://twitter.com/oauth/request_token' AUTHORIZATION_URL = 'http://twitter.com/oauth/authorize' AUTHENTICATE_URL = 'http://twitter.com/oauth/authenticate' ACCESS_TOKEN_URL = 'http://twitter.com/oauth/access_token' then *everything*, including signout and signup, works. This also matches the instructions at http://twitter.com/oauth_clients/details/%d. However, it strikes me as odd that the oauth stuff half works at api.twitter.com. My question is: What is the bug? That the api.twitter.com oauth endpoints only partially work -- in which case tweepy is fine and I should file a bug with Twitter -- OR that the api.twitter.com oauth works at all -- in which case I should ping the author of tweepy and perhaps suggest to Twitter that they remove this partial functionality to prevent future confusion? Many thanks, Josh
Re: [twitter-dev] Oauth using api.twitter.com vs twitter.com
Hey Shiplu, I've found that this works, until the user tries to sign out or sign up during the authorization; if this happens, they get a 404. If, however, twitter.com is used as the host: I think this happens due to cookie. People sign in twitter.com. not in api.twitter.com. When a user already signed in, the cookie's domain is twitter.com. Thanks for the suggestion. However, this is definitely url/host/routing related, not cookie related. (a) I can reproduce after clearing all cookies. (b) The cookie api.twitter.com sets has .twitter.com as its domain. (c) http://api.twitter.com/signup?oauth_token=removed yields a 404; http://twitter.com/signup?oauth_token=removed does not. (d) The issue is not that it doesn't remember the user, but rather that the sign out and sign up links on the oauth page are broken (lead to 404s). -josh
Re: [twitter-dev] Oauth using api.twitter.com vs twitter.com
Hey Josh, Good to see I reached you, albeit not through the channel I'd anticipated. :) I really think the issue is quite simple; sorry I haven't expressed it clearly enough. If you look at the source of the http://(api.)?twitter.com/oauth/authorize page, you'll see that the sign up link is a relative url: a href=/signup?oauth_token=removedSign up and Join the Conversation!/a And http://api.twitter.com/signup?oauth_token=removed yields a 404 but http://twitter.com/signup?oauth_token=removed does not. So either (1) one is only supposed to use twitter.com for oauth/authorize, or (2) Twitter ought to be using an absolute url to point to http://twitter.com/signup, or (3) http://api.twitter.com/signup oughtn't be a 404, but a signup page. All the same goes, mutatis mutandis, for the sign out page. Hope that clarifies the issue a little. Oh, and by the way, thanks for the awesome library. :) -josh On Thu, Dec 17, 2009 at 3:16 PM, Josh Roesslein jroessl...@gmail.com wrote: Sorry left off the link to the issue.
