Do **not** merge yourself and do **not** proceed until the user has reviewed and merged it — +the libgit2 build is about to trust these hashes. + +## Step 2 — Rebuild the native archive (`build.yml`, `publish=true`) + +```bash +gh workflow run build.yml --repo UiPath/libgit2sharp.nativebinaries --ref -f publish=true +gh run list --repo UiPath/libgit2sharp.nativebinaries --workflow build.yml --limit 1 --json databaseId +gh run watch --repo UiPath/libgit2sharp.nativebinaries --exit-status +``` + +It fetches + SHA256-verifies the deps (no OpenSSL/libssh2 compile), builds libgit2 for all 6 RIDs, +assembles `natives-.zip`, and — because `publish=true` (or on `develop`) — publishes Release +**`natives-`**. `` comes from **MinVer** on the nativebinaries repo, reformatted to a +single auto number `X.Y.Z-v` (base tag `1.9.1-v5` + height 1 → `1.9.1-v6`; see Reference). +Find the exact tag: + +```bash +gh release list --repo UiPath/libgit2sharp.nativebinaries --limit 5 # newest natives-* is yours +``` + +## Gate B — Roll the natives pin into `natives.lock.json` (this repo) + +```bash +NTAG=natives- +gh release download "$NTAG" --repo UiPath/libgit2sharp.nativebinaries --pattern '*.sha256' --dir "$TMPDIR/natsha" +pwsh ./.claude/skills/release-libgit2-natives/Update-Lockfile.ps1 \ + -LockfilePath ./natives.lock.json -Tag "$NTAG" -ShaDir "$TMPDIR/natsha" +# prove it fetches + verifies before trusting the pin: +pwsh ./fetch.natives.ps1 -Force +``` + +`fetch.natives.ps1` fails hard on a SHA mismatch, so a green fetch confirms the pin. **Human gate:** +show the `natives.lock.json` diff, confirm, then **create a new branch, commit, push, and open a PR** +(`gh pr create`) against `develop`. Do **not** merge yourself — the PR's `ci.yml` run exercises +windows/ubuntu/macos, and the user reviews and merges. + +## Step 3 — Ship the managed package (the very last step) + +**Versioning — nothing to do.** The package version is `X.Y.Z-v` (e.g. `1.9.1-v6`), a single auto +number where **`N = the base tag's epoch + the MinVer height`**. The base tag `1.9.1-v5` sets the epoch +(5) and each commit past it increments N (v6, v7, …), computed by the managed repo's `AdjustVersions` +target and the nativebinaries `build.yml` "Resolve version" step. Every develop commit yields the next +`v` — no manual version tagging. + +**Re-tagging is seamless** (unlike a height-only scheme). Because `N = epoch + height`, on the tag +commit itself height is 0, so `v` equals the tag — cutting a new tag at the **current** `v` (e.g. +`git tag 1.9.1-v20` when the version already reads `v20`) just re-bases the epoch with no jump, and the +number keeps climbing. Only pitfall: never tag **below** the current `v`, or the version goes +backwards (NuGet forbids). New upstream base → `git tag X.Y.Z-v0`. Same scheme in the nativebinaries repo. + +**Publishing to the uipath-internal feed — done interactively from here** (like the gates: there is +no CI publish job). Once the Gate B PR is merged to `develop` and CI is green, get the +`LibGit2Sharp.UiPath` nupkg — download the managed CI's **NuGet packages** artifact, or build locally +(`dotnet build -c Release` emits it under `bin/Packages/`, via `GeneratePackageOnBuild`). + +**Recommended — mint a short-lived Azure DevOps token via the Azure CLI** (no stored PAT, reuses your +`az login` SSO): + +```bash +FEED=https://pkgs.dev.azure.com/uipath/Public.Feeds/_packaging/UiPath-Internal/nuget/v3/index.json +# 499b84ac-... is the well-known Azure DevOps resource id +TOKEN=$(az account get-access-token --resource 499b84ac-1321-427f-aa17-267ca6975798 --query accessToken -o tsv) +dotnet nuget add source "$FEED" --name uipath-internal 2>/dev/null || true +NuGetPackageSourceCredentials_uipath-internal="Username=az;Password=$TOKEN" \ + dotnet nuget push ".nupkg" --source uipath-internal --api-key az --skip-duplicate +``` + +**Fallback** — if the Azure Artifacts credential provider is already configured on the machine, just: +`nuget push -src "$FEED" -ApiKey AzureDevops -SkipDuplicate`. + +`--api-key`/`-ApiKey` is a required-but-ignored dummy (auth is the token / credential provider, not the +key). `--skip-duplicate` keeps it idempotent — and matters here: the feed may already hold a +manually-published `1.9.1-v5`, so the emitted `X.Y.Z-v` must **exceed** the highest version +already on the feed (see the version-collision caveat). Human-run step — confirm the exact version with +the user before pushing. Only if the upstream base changed: `git tag X.Y.Z-v0` once, first. + +--- + +## Reference + +**Lockfile shapes** (both carry a `repo` field the atom reads to rebuild URLs): +- `deps.lock.json` (sibling repo): `{ repo, tag, platforms: { : { filename, url, sha256 } } }`, + 6 RIDs. Windows = `.zip` (dynamic DLLs); posix = `.tar.gz` (static `.a`, symlinks preserved). +- `natives.lock.json` (this repo): `{ repo, tag, filename, url, sha256 }`, one archive; `filename` is + always `.zip`. + +**MinVer** — both repos use `X.Y.Z-vN` base tags with `--default-pre-release-identifiers preview.0`. +MinVer emits `X.Y.Z-v.` (e.g. `1.9.1-v5.1`); both repos reformat to +**`X.Y.Z-v`** (e.g. `1.9.1-v6`) — a single auto number that continues from the tag. +MinVer's height is the *shortest graph distance* to the tag, so it stays small after a merge (the base +tag often lands on the merge commit's first parent — that's why a naive height-only scheme wrongly +produced `v1`); epoch+height keeps climbing regardless. New upstream base → `git tag X.Y.Z-v0`. + +**Release gating** — `build.yml`'s publish step is gated on `inputs.publish || github.ref == +refs/heads/develop`. PR/branch runs without `publish=true` produce only a workflow artifact (no stray +release). Always pass `-f publish=true` when you actually want the durable natives Release. + +**`build-deps.yml`** is manual (`workflow_dispatch`) only — never on push — so a rebuild can't +silently republish archives with fresh, unpinned SHA256s. + +**Sidecar formats differ** (the atom handles both): deps sidecars are a bare hash; the natives +sidecar is `sha filename` (sha256sum format). `Update-Lockfile.ps1` takes the first token either way. + +**Testing off a branch** — `gh workflow run … --ref ` dispatches the workflow as it exists on +that branch, so you can validate the whole chain before merging to `develop`. + +**Gotchas** +- The deps rebuild is gated on the version existing in vcpkg's registry at the pinned baseline — + budget time for a `builtin-baseline` bump, not just a submodule checkout. +- The libgit2 submodule is private; `build.yml` clones it via the `LIBGIT2_DEPLOY_KEY` secret + (read-only deploy key).
