just a thought, but an utuility that returns a unique_ptr on the mi-heap with a custom deleter would be helpful, we do this currently for some pointers in connection

Maybe but then we will increase the class size

it's only called to pass it into BitIndex()

Yes, you want to move it into cc?

you actually don't need all of this if you just use vector<bool> 🤔 It has proxies that allow you to reference a specific bit in its internal structure

You are right but then I need to pass mimalloc memory resource etc. it's not a lot of code and I won't object to reducing it in the future if memory usage with vector bool won't increase.

…nfly ( v1.15.1 → v1.16.0 ) (#3354) This PR contains the following updates: | Package | Update | Change | |---|---|---| | [docker.dragonflydb.io/dragonflydb/dragonfly](https://togithub.com/dragonflydb/dragonfly) | minor | `v1.15.1` -> `v1.16.0` | --- ### Release Notes <details> <summary>dragonflydb/dragonfly (docker.dragonflydb.io/dragonflydb/dragonfly)</summary> ### [`v1.16.0`](https://togithub.com/dragonflydb/dragonfly/releases/tag/v1.16.0) [Compare Source](https://togithub.com/dragonflydb/dragonfly/compare/v1.15.1...v1.16.0) ##### Dragonfly v1.16.0 Our spring release. We are getting closer to 2.0 with some very exciting features ahead. Stay tuned! Some prominent changes include: - Improved memory accounting of client connections ([#​2710](https://togithub.com/dragonflydb/dragonfly/issues/2710) [#​2755](https://togithub.com/dragonflydb/dragonfly/issues/2755) and [#​2692](https://togithub.com/dragonflydb/dragonfly/issues/2692) ) - FT.AGGREGATE call ([#​2413](https://togithub.com/dragonflydb/dragonfly/issues/2413)) - Properly handle and replicate Memcache flags ([#​2787](https://togithub.com/dragonflydb/dragonfly/issues/2787) [#​2807](https://togithub.com/dragonflydb/dragonfly/issues/2807)) - Intoduce BF.AGGREGATE BD.(M)ADD and BF.(M)EXISTS methods ([#​2801](https://togithub.com/dragonflydb/dragonfly/issues/2801)). Note, that it does not work with snapshots and replication yet. - Dragonfly builds natively on MacOS. We would love some help with extending the release pipeline to create a proper macos binary. - Following the requests from the Edge developers community, we added a basic HTTP API support! Try running Dragonfly with: `--expose_http_api` flag and then call `curl -X POST -d '["ping"]' localhost:6379/api`. We will follow up with more extensive docs later this month. - Lots of stability fixes, especially around Sidekiq and BullMQ workloads. ##### What's Changed - chore: make usan asan optional and enable them on CI by [@​kostasrim](https://togithub.com/kostasrim) in [dragonflydb/dragonfly#2631 -
