How do you upload the file?
just using the web interface
I tried to find out myself where the call was being made on the code, PHP isn't my thing, but I think it might have to do with a function called stat or fopen or something causing that call? but at the end I couldn't figure it out. I might give it another try. any tips on how I could debug that? or anything else I could do?

Did you adjust the chunk size / turned chunking off? The default is 10mb and parts should always use putObject until you tweak the value to be bigger than 100mb (the default putSizeLimit).

Not really. In my tests, I saw some weird behavior with mitmproxy. I think that was caused because we use request_fulluri when a proxy is defined.

4 months ago the only setting I changed from the default is uploadPartSize with a value of 67108864 as per Storj recommendation

4 months ago The empty put request is coming from: https://github.com/nextcloud/server/blob/ddb840c36babd02abedce7da41b0c04849009edb/apps/dav/lib/Upload/ChunkingV2Plugin.php#L99
As I understand it, it's a placeholder for the file to be uploaded.

4 months ago I see... CreateMultipartUpload already creates the file, though

6 days ago Issue persist in nextcloud 29.0.9
I worked around the issue by adding a 1sec sleep after file touch operation in /lib/private/Files/View.php
The dual operation touch+upload for S3 makes little sense. S3 does create or overwrite files on upload and it needs extra features to handle lock and concurrency.
⚠️ This issue respects the following points: ⚠️
Bug description
When using an S3-like object storage as primary storage, and uploading a big file that goes beyond the
putSizeLimitsetting (so it's going to be a multipart upload), an empty PutObject request is sent just before the S3 CreateMultipartUpload method, causing rate limits (HTTP 429) on some providers like Storj that limit concurrent requests.At first glance this seems completely unnecessary, because the object will already be created by the CreateMultipartUpload method.
The following screenshot (using MITM Proxy) shows the request trace when I try to upload a big file twice (the first two requests can be ignored. The POST ones are the ones that should initiate the multipart upload, but fail with a 429 code and a Retry-After header value of 5 seconds
Steps to reproduce
putSizeLimitthreshold (default: >100MB)Expected behavior
Uploads of bigger files work because no unnecessary PutObject request is made before starting the multipart upload
