Trouble with incremental initial sync with OAuth

[sziegler]

Hi Springpad-Developers,

I'm currently switching my app OrganizeMe! from username/password authentication to OAuth and I encountered some issues during that modifications.

The first sync I do is with the following URL and this one is executed correctly:

http://springpad.com/api/users/me/blocks?&limit=25&format=sync&sd=true&createdAfter=0&oauth_timestamp=1365961130&oauth_nonce=STN03g&oauth_signature=wQcZXYiur2NW%2FGFIRJiniTlChqc%3D&oauth_consumer_key=08abfc557f854d60aecbb550b83a1ec6&oauth_token=ccec43b708a46bf20e2e01ed03ceb568&oauth_version=1.0&oauth_signature_method=HMAC-SHA1

Because my account has more than 25 blocks, I try to fetch the next page with the "X-Spring-Next-Page-Date" as timestamp for the "createdAfter" parameter:

http://springpad.com/api/users/me/blocks?&limit=25&format=sync&sd=true&createdAfter=1362153964430&oauth_timestamp=1365961132&oauth_nonce=yaLnRT&oauth_signature=P%2BvDSSCd3PEuchDvQ%2FaRLjhdbK8%3D&oauth_consumer_key=08abfc557f854d60aecbb550b83a1ec6&oauth_token=ccec43b708a46bf20e2e01ed03ceb568&oauth_version=1.0&oauth_signature_method=HMAC-SHA1

This whole process worked like a charme with the old authentication mechanism, but with OAuth I'm getting xhr error code 500 with this error meesage:

{
"status":"error",
"message":"java.lang.String cannot be cast to java.util.List"
}

I've got no clue what's going wrong here. I've just created a new XHR request, changed the createdAfter parameter and signed it with OAuth the same way as usual...

Any help would be greatly appreciated!

Best,

Sven

Hi Sven.  That looks like a bug on our side.  Can you tell me the username you used for this?

Thanks,

Chuck

[Sven Ziegler]

Sure: "svzi".

Hi Chuck,

is there anything I can do? Did you find the cause for my user?

Best,

Sven

[Chuck Garofalo]

Hi Sven.  I'm sorry I didn't get back to you sooner.  I did find the root cause and I put in a fix but it hasn't been deployed yet.  We expect to do that today.  I will verify my fix and respond back later.

Regards,

Chuck

Hi Chuck,

great news, I hope your fix will work. I really appreciate your support.

Best,

Hi Sven.  We just released the changes that I think should fix your problem here.  I checked the problematic block using the api and it no longer gives an error.  Please let me know if you still have trouble.

Regards,

Chuck

Hi Chuck,

I'm really sorry, but nothing has changed for me. I'm using this request:

http://springpad.com/api/users/me/blocks?&limit=25&format=sync&sd=true&createdAfter=1362153964430&oauth_timestamp=1366320244&oauth_nonce=iWQa2y&oauth_signature=K1shNINYf7C8SfvVWcbgPWmT2DE%3D&oauth_consumer_key=08abfc557f854d60aecbb550b83a1ec6&oauth_token=a72e8f5605cb5bb875745c8cb06849f5&oauth_version=1.0&oauth_signature_method=HMAC-SHA1

And I'm getting the same error as before:

{

"status":"error",
"message":"java.lang.String cannot be cast to java.util.List"
}

Hi Sven.  Yes, I'm sorry my fix didn't work for this issue.  I found another error and I'm pretty sure it is the root of your problem now.  I have a potential fix but it likely won't get out until next week.  If you are able to identify the offending block and can use the api to clear out the "contactInfo" property, that should also clear up the issue.

I'll follow up when my fix is out.

Regards,

Chuck

[Sven Ziegler]

Hi Chuck,

I don't think that clearing out the "contactInfo" property would be a good idea, because we would lose the testcase for the bugfix. How should we now if your next bugfix will correct the error or not? I'm thankful for this error. It's always better to find this with my own account, instead of when someone of my users does find this. :-)

Sven

Hi Chuck,

do you have any timetable for when the fix will be released? I'm currently stuck in my efforts to switch the app to OAuth because I can't get enough test data... So it would be helpful to me if I could knew a possible date when this should be fixed.

Thanks again for your help and I don't want to hurry you.

Best,

Sven

[Chuck Garofalo]

Hi Sven.  Sorry it is taking so long.  We will be releasing later this week this and other fixes together.  It will be either Thursday afternoon or Friday morning.  

Regards,

Chuck

Hi Chuck,

don't worry, but I'm a little bit confused. I tried to sync a few hours ago and the error is gone. So I thought you forget to notice me and you already submitted the fix. Strange, but good. Maybe you want to have a look at the logs again, something should have fixed my issue?!

Best,

Sven

Hi,

I sadly discovered another issue, which is, in my opinion, not depended to OAuth. It's still an issue with the incremental initial sync.

When I sync my account with createdAfter parameter and limit = 25, then I sometimes got responses with less then 25 elements, but the sync is not finished. When I sync again it will fetch more objects. I don't know why this happens, but it's not related to my account, because one of my beta testers did discover the issue by himself, too.

For me it looks like it would be more secure to sync until the response is empty and not until the response got less then [limit] elements. Could you confirm that as a good approach?

Best,

Sven

[Chuck Garofalo]

Hi Sven.  Can you try again now?  We released my fix this afternoon.

[sziegler]

Hi Chuck,

please have a look at my post from 04/23/2013. I do not have the issue
since that date, as described in that posting, but I got a new issue. Have
a look at my post from today in this thread please. :-)

Best,
Sven

[Chuck Garofalo]

Hi Sven.  Sorry I missed that one.  It should continue to give you all of your items in at least (but potentially more) groups of 25 and if you get fewer that should be your stopping condition.  I'll take a look as soon as I can this week.  

Regards,

Chuck

[sziegler]

Hi Chuck,

don't worry. I knew that this had worked before, but as I stated before I sometimes got less then 25 and sync is not finished. And this did not only happen with my account... Would be great if you could have a look in the next time.

Best,

Sven
