* Implement ListMultipartUploads (#171)Quentin2022-01-121-1/+2
| | | | | | | | | | | | | | | | | | | | | | | Implement ListMultipartUploads, also refactor ListObjects and ListObjectsV2. It took me some times as I wanted to propose the following things: - Using an iterator instead of the loop+goto pattern. I find it easier to read and it should enable some optimizations. For example, when consuming keys of a common prefix, we do many [redundant checks](https://git.deuxfleurs.fr/Deuxfleurs/garage/src/branch/main/src/api/s3_list.rs#L125-L156) while the only thing to do is to [check if the following key is still part of the common prefix](https://git.deuxfleurs.fr/Deuxfleurs/garage/src/branch/feature/s3-multipart-compat/src/api/s3_list.rs#L476). - Try to name things (see ExtractionResult and RangeBegin enums) and to separate concerns (see ListQuery and Accumulator) - An IO closure to make unit tests possibles. - Unit tests, to track regressions and document how to interact with the code - Integration tests with `s3api`. In the future, I would like to move them in Rust with the aws rust SDK. Merging of the logic of ListMultipartUploads and ListObjects was not a goal but a consequence of the previous modifications. Some points that we might want to discuss: - ListObjectsV1, when using pagination and delimiters, has a weird behavior (it lists multiple times the same prefix) with `aws s3api` due to the fact that it can not use our optimization to skip the whole prefix. It is independant from my refactor and can be tested with the commented `s3api` tests in `test-smoke.sh`. It probably has the same weird behavior on the official AWS S3 implementation. - Considering ListMultipartUploads, I had to "abuse" upload id marker to support prefix skipping. I send an `upload-id-marker` with the hardcoded value `include` to emulate your "including" token. - Some ways to test ListMultipartUploads with existing software (my tests are limited to s3api for now).

* New buckets for 0.6.0: small changesAlex Auvolat2022-01-041-5/+11
| | | | | | | | | | | | - Fix bucket delete - fix merge of bucket creation date - Replace deletable with option in aliases Rationale: if two aliases point to conflicting bucket, resolving by making an arbitrary choice risks making data accessible when it shouldn't be. We'd rather resolve to deleting the alias until someone puts it back.

* Improve how node roles are assigned in Garagev0.5-beta1Alex Auvolat2021-11-161-2/+2
| | | | | | | | | | | | | | | | | - change the terminology: the network configuration becomes the role table, the configuration of a nodes becomes a node's role - the modification of the role table takes place in two steps: first, changes are staged in a CRDT data structure. Then, once the user is happy with the changes, they can commit them all at once (or revert them). - update documentation - fix tests - implement smarter partition assignation algorithm This patch breaks the format of the network configuration: when migrating, the cluster will be in a state where no roles are assigned. All roles must be re-assigned and commited at once. This migration should not pose an issue.
