The lock is also taken when iterating on a table with `.iter()`, and the lock isn't released until the iterator is dropped. This means that we must be VERY carefull to not do anything else inside a `.iter()` loop or else we will have a deadlock! Most such cases have been eliminated from the Garage codebase, but there might still be some that remain. If your Garage-over-Sqlite seems to hang/freeze, this is the reason. - (adapter uses a bunch of unsafe code) - Heed (LMDB): - Not suited for 32-bit machines as it has to map the whole DB in memory. - (adpater uses a tiny bit of unsafe code) **My recommendation:** avoid 32-bit machines and use LMDB as much as possible. **Converting databases** is actually quite easy. For example from Sled to LMDB: ```bash cd src/db cargo run --features cli --bin convert -- -i path/to/garage/meta/db -a sled -o path/to/garage/meta/db.lmdb -b lmdb ``` Then, just add this to your `config.toml`: ```toml db_engine = "lmdb" ``` Co-authored-by: Alex Auvolat <alex@adnab.me> Reviewed-on: https://git.deuxfleurs.fr/Deuxfleurs/garage/pulls/322 Co-authored-by: Alex <alex@adnab.me> Co-committed-by: Alex <alex@adnab.me>

* Implement UploadPartCopyAlex Auvolat2022-01-131-0/+14

* Implement ListMultipartUploads (#171)Quentin2022-01-121-3/+11
| | | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | - 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.

* Improve how node roles are assigned in Garagev0.5-beta1Alex Auvolat2021-11-161-4/+5
| | | | | | | | | | | | | | | | | - 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.
