Aliyun OSS Incompatibility

[GZGavinZhao]

Hi! I'm using sccache with Aliyun Object Storage Service, which is S3-compatible. However, I keep getting cache write errors. I've tested my API credentials and made sure they were working.

I suspect the problem is with the URL. This short issue (kahing/goofys#336) explains it much better than I can. In short, OSS only supports virtual hosted-style URLs, while sccache uses path-based access.

OSS docs on S3-compatibility: https://www.alibabacloud.com/help/en/object-storage-service/latest/s3-compatibility-overview

AliyunOSS is not exactly S3 compatible.

@feuvan Yes, it's not 100% compatible, but for the sccache use case it is enough and the slight difference between OSS and S3 is not the cause of this issue. #1086 will fix this.

I will working on this issue after existing storage services have been migrated to opendal.

I plan to add a new OSS service support via opendal's native support: opendal::services::oss

@Xuanwo Hi, Any progress on this issue？ I'm trying to use OSS now and seeing SecondLevelDomainForbidden errors. Then I found this link https://github.com/apache/incubator-opendal/blob/main/core/src/services/s3/compatible_services.md in OpenDAL. Is this a good solution?

Hi, thanks for the question.

First of all, OSS native support is not added yet. I will continue this work after #1885 get merged.

Then, as described in opendal's docs, we need a new option called enable_virtual_host_style to access OSS like bucket.oss.example.com instead of oss.example.com/bucket. We can address this in #1887.

Please let me know if you are interested in those works. I am willing to provide assistance with implementation and review.

Is it still active? Looks like we’re added the Alibaba OSS support to the sccache
