## Qdrant Edge
## permutation_iterator
AI Studio temporarily uses a pinned commit from `SommerEngineering/qdrant` for `qdrant-edge`.
The fork commit exposes Qdrant's internal `lib/edge` crate as `qdrant-edge` and applies the
trait-solver fix from Qdrant PR #9312.
`qdrant-edge` depends on `permutation_iterator 0.1.2`, and that crate has seen no release since
2019. Its published version pulls in an outdated `rand` line, which drags a second copy of the
whole `rand` family into our dependency tree: `rand 0.7.3`, `rand_core 0.5.1`, `rand_chacha 0.2`,
`rand_hc`, `getrandom 0.1.16`, `wasi 0.9` and `cfg-if 0.1`, next to the current ones everything
else uses.
When updating to a newer Qdrant Edge version, replace the placeholder values first:
The fork `SommerEngineering/permutation-iterator-rs` is the published 0.1.2 with `rand` raised to
0.8, so it still satisfies what `qdrant-edge` asks for. AI Studio pins it in `runtime/Cargo.toml`:
```bash
export QDRANT_EDGE_VERSION="0.7.2"
export QDRANT_BRANCH="ai-studio-qdrant-edge-${QDRANT_EDGE_VERSION}"
export AISTUDIO_REPO="xxx/mindwork-ai-studio"
export QDRANT_REPO="xxx/qdrant"
```toml
[patch.crates-io]
permutation_iterator = { git = "https://github.com/SommerEngineering/permutation-iterator-rs.git", rev = "..." }
```
1. Sync the Qdrant fork with upstream:
The same change was offered upstream in
[asimihsan/permutation-iterator-rs#14](https://github.com/asimihsan/permutation-iterator-rs/pull/14),
where it has been waiting since 2021. This is tree hygiene, not a build failure: without the patch
the runtime still builds, it just carries the old `rand` family along.
```bash
cd "$QDRANT_REPO"
git remote add upstream https://github.com/qdrant/qdrant.git 2>/dev/null || true
git fetch upstream
git fetch origin
git switch master
git merge --ff-only upstream/master
git push origin master
```
### When this patch can go
2. Create a fresh AI Studio branch in the Qdrant fork:
Either of these is enough, and both are worth a look whenever `qdrant-edge` is updated:
```bash
cd "$QDRANT_REPO"
git switch -c "$QDRANT_BRANCH" master
```
- crates.io carries a `permutation_iterator` newer than 0.1.2 which uses a current `rand`. Then the
`[patch.crates-io]` entry goes, and `qdrant-edge`'s own requirement decides the version.
- `qdrant-edge` stops depending on `permutation_iterator` at all. Check with
`cargo tree -i permutation_iterator` after the update.
3. Apply the AI Studio patch if upstream has not released the fix yet:
```bash
cd "$QDRANT_REPO"
git apply "$AISTUDIO_REPO/runtime/patches/qdrant-edge-ai-studio.patch"
```
4. Update the exposed `qdrant-edge` version in the fork:
```bash
cd "$QDRANT_REPO"
perl -0pi -e "s/name = \"qdrant-edge\"\\nversion = \"[^\"]+\"/name = \"qdrant-edge\"\\nversion = \"$ENV{QDRANT_EDGE_VERSION}\"/" lib/edge/Cargo.toml
```
5. Commit and push the fork branch:
```bash
cd "$QDRANT_REPO"
git diff
git add lib/edge/Cargo.toml lib/segment/src/common/anonymize.rs
git commit -m "Expose qdrant-edge ${QDRANT_EDGE_VERSION} package for AI Studio"
git push origin "$QDRANT_BRANCH"
export QDRANT_EDGE_COMMIT="$(git rev-parse HEAD)"
echo "$QDRANT_EDGE_COMMIT"
```
6. Update AI Studio to use the new Qdrant Edge version and fork commit:
```bash
cd "$AISTUDIO_REPO"
perl -0pi -e "s/qdrant-edge = \"[^\"]+\"/qdrant-edge = \"$ENV{QDRANT_EDGE_VERSION}\"/" runtime/Cargo.toml
perl -0pi -e "s/rev = \"[0-9a-f]+\"/rev = \"$ENV{QDRANT_EDGE_COMMIT}\"/" runtime/Cargo.toml
```
7. Refresh the AI Studio lock file and verify the Rust runtime:
```bash
cd "$AISTUDIO_REPO/runtime"
cargo update -p qdrant-edge
cargo check
```
Remove the patch and the `[patch.crates-io]` override once Qdrant publishes a fixed `qdrant-edge`
release on crates.io.
Afterward, `grep 'name = "rand"' -A 2 runtime/Cargo.lock` must not show a 0.7 version anymore.
`SommerEngineering/permutation-iterator-rs` can then be deleted.
