Meta-data unreliable in DBFILESUploadSessionFinishBatchResultEntry?
Hello, I'm using chunked uploads to upload files (although this may affect regular uploads, too - I haven't checked that yet). I use the clientDate parameter of DBFILESCommitInfo to ensure the di...
- Ok, the fix is rolling out now. I just tried the sample code again, and it's no longer reproducing the issue for me.
Please try it out when you get a chance and let me know if you're still seeing the issue.

Dropbox Community ModeratorActually, we've found a case where this can occur. We're working on it, and I'll follow up here once I have an update for you.
Hi Greg,
Great, glad you've found a case! This is actually happening consistently for me, though - I get random results every single time I try. I've created a test project in case it helps. You can download it here:
https://dl.dropboxusercontent.com/u/24954/DBChunkedUploadBug.zip
To use:
1. Build and run in Xcode 8 on macOS 10.12.
2. Tap "Sync" to link Dropbox.
3. Tap "Sync" again to upload a bunch of files. The code will create a "ChunkedUploadsTest" folder at the root of your Dropbox folder, and into that it will upload 26 text files containing "lorem ipsum" text, with file names from A to Z.
The code iterates through the DBFILESUploadSessionFinishBatchResultEntry entries array using a for() loop, and it uses the index to retrieve both the DBFILESUploadSessionFinishBatchResultEntry object from the entries array and a custom task object from another array that is in exactly the same order as the finish args array passed into -uploadSessionFinishBatch:. It looks the file name of both the batch result entry and the custom task object with a divider between them. From this, you can see from the output on the Console that the results do not match - the DBFILESUploadSessionFinishBatchResult entries array is never in the same order as the finish args array passed into -uploadSessionFinishBatch:.
All the relevant Dropbox code can be find in the MasterViewController.m file.
As I say, I have another way of getting the information I need, so this isn't holding me back, but hopefully the sample project will help confirm that the case you have found is the same as what I am experiencing.
All the best,
Keith

Thanks Keith! It's possible that the issue only reliably reproduces on some accounts/files and not others.
We just deployed a fix. Can you try again and let me know if you're still seeing the issue or not? Thanks!
Hi Greg,
Unfortunately, I'm getting exactly the same results as before (using the sample app I sent you). I wasn't sure whether the fix was on the server side or in the Obj-C frameworks, though. So, I first just tried running the sample app, and I got the same results as before - the order of the entries array is entirely random and does not match the finishArgs array.
I then tried re-downloading the Obj-C framework, but unfortunately after re-downloading it wouldn't build for me, constantly telling me that DBTaskStorage.h was missing. (Then, when I swapped back to the older framework that was working before, it built, but with loads of warnings about missing parameters, apparently picking up the @param keywords in the comments of the header frameworks, bizarrely - I'm not sure what I've messed up there!) I'm sure the problems with the framework are something silly I'm doing, but I'm off for a week away in a couple of hours, so I'm afraid I don't have time to look into what's gone wrong before I go.
So, because I'm away for a week (which at least means you get a breather from the barrage of questions :) ), if the fix is in the Obj-C framework, I won't be able to test it until I get back next weekend - sorry about that. If the change was on the server side, though, then I'm afraid it doesn't seem to have fixed anything.
Many thanks,
Keith
- Greg-DBThanks Keith. It was a server-side fix, so we'll keep investigating. And thanks for the sample project! I'll try that out.
