Storj S3 restore Error: "cannot find max wal index for restore: missing initial wal segment:"

I am using Stroj S3 bucket for backup. Everything works fine as intended - backup are created in the bucket, I can see those files, I can use litestream restore command to restore the database too. But after the litestream replicate task keeps running for some time (few minutes to hours) and there are some DB write, somehow the backup in S3 gets corrupted and I get this error when I run litestream restore
$ ./litestream restore -config ./litestream.conf -o ./xxx/db_restore.sqlite3 -replica storjEU data/db.sqlite3
time=2023-12-11T13:19:05.215Z level=ERROR msg="failed to run" error="cannot find max wal index for restore: missing initial wal segment: generation=93602482baf2a8be index=00000002 offset=4152"
ABOVE FAILS, BUT THIS WORKS:
$./litestream restore -config ./litestream.conf -o ./xxx/db_restore.sqlite3 -replica local data/db.sqlite3
Surprisingly this issue is not happening with my backup/replication copy on the local file system. The local and Strorj S3 replications are both happening at the same time, but only the S3 copy is getting corrupted.

I am using latest version of Litestream from GitHub release.
Tried on both amd64 and arm64 platforms.
I have made 100% sure that no two separate instances/servers are replicating to the same target S3 path. I am aware that can produce this particular error (https://litestream.io/tips/#multiple-applications-replicating-into-location-can-corrupt)
Can you please suggest why this is happening? I have search though old githib issues and entire documentation, but couldn't find any clue.
hifi commented
Might be #522, a full log of Litestream is necessary to debug with a full recursive file listing of the bucket/backend state.
I have several PRs open that fix various issues related to this but to diagnose the exact one I'd need to see what the latest Litestream logged. Even the current recursive file listing would be useful.
Thanks!
(I'm not the maintainer but I dealt with this stuff recently)

Thanks for your reply.
I don't have the full log (yet). I will restart LS, start the trace, and wait for the issue to reappear.
However, this is the current state (corrupted) of the file list in S3 remote:

I reordered the generation files alphabetically.
SubhashBose commented
Yes, I am sure.
After generating this file list. I again re-ran the litestream restore command, and it showed the same above error '.... generation=93602482baf2a8be ....'
hifi commented
Is that list from aws s3 ls? I think it should be ordered by key and that might be the issue here 🤔
Can you do a test where you make a full clone of the bucket to a local path and try restoring from that if it's indeed an ordering problem? Because the file is there it shouldn't get confused like that.
SubhashBose commented
The list I am getting is using rclone.
By the way, this is not AWS, this is Storj S3 storage.
However, to get a log of the litestream, I have stopped and re-started litestream replicate command, and now I am dumping the stdout of the litestream to a file. As expected this has temporarily fixed the S3 remote's copy, and I can do the restore now. I will report back with the log when the problem reappears in few hours.

so I can not do this test. will do it when I again get the error.
SubhashBose commented
Okay, I could capture the same error again after a few writes to the database.
Here you can find the error message, generation and snapshot states, full file list from S3 remote, and the output/stdout when `litestream replicate' was running
https://rentry.co/litestream-s3-bug
As you asked, I downloaded the full list of files from S3 remote and ran restore locally, and now the restore works without any error. So litestream is somehow reading the file list improperly.
--- Below is not relevant anymore, see next comment ---
So, below is the output of restore when I ran locally. But I am not sure if this is the last backup copy of the database, can you please confirm?
I don't understand how litestream identifies the latest snapshot/wal, but looking at the snapshots or generations output (given in the link above), this id 921b3b26c504a437 doesn't look like the latest one.

In continuation of my last comment:
I just discovered that litestream relies on mod-time of files in the backup directory. This is a huge red-flag for me on the reliability of a backup system, as modtime can quite easily be messed up when moving files across storages. Atleast, the cruciality of mod-time should be emphasized in the litestream documentation, so that users can be aware of the limitations.
Anyway, during my previous test on local clone of S3 remote, I didn't preserve the mod-time. That is why it was restoring the wrong snapshot+wal. After, I preserved the mod-time while cloning, litesream selected the correct generation/snapshot `7b6ac7d25b62c052' as the latest one.

To summarize, if I make a copy of S3 remote file to local path and do the litestream restore, then it works fine. But, when reading from S3 remote directly, litestream restore fails with the error cannot find max wal index for restore: missing initial wal segment: ..... Can you suggest a remedy for this?
hifi commented
Since it works locally from a copy my best guess is the same that Storj doesn't adhere to the S3 LIST promise of returning all objects ordered. That's why I asked if the listing was from aws s3 ls because it should be quite raw what it does with the S3 API (of Storj).
If the order is in fact not correct then you should file a bug report for Storj that they must return it ordered:
https://docs.aws.amazon.com/AmazonS3/latest/userguide/ListingKeysUsingAPIs.html
List results are always returned in UTF-8 binary order.
SubhashBose commented
I am looking at Stroj S3 api docs, and they mention this
https://docs.storj.io/dcs/api/s3/s3-compatibility#list-objects
A bucket's paths are end-to-end encrypted. We don't use an ordering-preserving encryption scheme yet, meaning that it's impossible to always list a bucket in lexicographical order (as per S3 specification).
So, maybe this is the issue.
Is it possible for litestream to do the sorting on client end, rather than relying on server?
If this is possible, then I think many more storage will become compatible with litestrem which do not adhere to exact S3 specifications.
I was also considering to use Rclone which can serve any remote as S3,. But now I am not sure it will be a good idea.
hifi commented
That is indeed the issue because Litestream expects them to be in order.
I think it's reasonable to add a configuration option for Litestream S3 client to buffer the list and reorder them client side to improve compatibility with non-AWS implementations. I would probably prefer it over #531 but it's up to @benbjohnson in the end. The PR might suffer from the same issue unless the SDK reorders them before returning.
So in practice your data is fine on Storj but Litestream is just a bit confused when restoring.
hifi commented
I opened a PR to fix this since the change was trivial enough it doesn't really need additional code or configuration options.
There's only one place where the order of WAL segments matter and it's only on restore and there was a sort implementation in the code already so I changed the promise of replicas to return unordered results and it should be all good now.
