## Summary
This PR improves reusable workflow support for Gitea Actions. The
parsing of the called workflow now happens on Gitea side, not on the
runner. When the caller becomes ready, Gitea fetches the called workflow
source, parses it, and inserts each child job into the database as a
`ActionRunJob` linked to the caller via `ParentCallJobID`. As a result,
every callee job is dispatched as its own task and its logs surface as
an independent job entry in the UI, rather than being inlined into the
caller's "Set up job" step.
This PR supports two kinds of `uses` :
- same-repo call: `uses: ./.gitea/workflows/foo.yaml`
- cross-repo call: `uses: OWNER/REPO/.gitea/workflows/foo.yaml@REF`
## **⚠️ BREAKING ⚠️**
External reusable workflows (`uses:
https://other-gitea-instance/OWNER/REPO/.gitea/workflows/test.yaml@REF`)
are no longer supported. To keep using them, clone the repositories to
the local instance.
## Main changes
### Execution model
- Each caller job carries `IsReusableCaller=true` and won't be fetched
by runners.
- `ParentCallJobID` can link a called job to its caller.
- Caller status is derived from its direct children.
### Workflow syntax
- `jobparser` now supports parsing `on: workflow_call` trigger with
`inputs:`, `outputs:`, and `secrets:` declarations.
- **Max nesting depth**: capped at `MaxReusableCallLevels = 9`, which
means a top-level caller may have at most 9 nested callers below it.
- **Cycle prevention**: at expansion time, `checkCallerChain` walks the
caller's ancestor chain via `ParentCallJobID` and rejects if the same
`uses:` string appears anywhere upstream (`reusable workflow call cycle
detected`). This catches both direct (`A -> A`) and indirect (`A -> B ->
A`) cycles.
### Cross-repo access
- To share reusable workflows from private repos, use `Collaborative
Owners` introduced by #32562
### Rerun semantics
- `expandRerunJobIDs` partitions the latest attempt's jobs into:
- a **rerun set**: jobs being rerun + downstream siblings within the
same scope.
- an **ancestor set**: reusable callers whose only *some* descendants
are being rerun (the caller itself is not).
- Cloning behavior for callers in `execRerunPlan`:
- **Caller is fully rerun** (caller's `AttemptJobID` in `rerunSet`):
none of its descendants are cloned. The caller is cloned with
`IsCallerExpanded=false`, and re-expansion (which reinserts the children
fresh) happens later when the resolver brings the caller to `Waiting`
again.
- **Caller is in ancestor set** (only some descendants rerun): the
caller is pass-through (`Status` will be updated by its fresh children).
Its non-rerun descendants are also pass-through clones (point
`SourceTaskID` at the original task). Their `ParentCallJobID` is
remapped to the new attempt's caller row.
### UI
- Job list in `RepoActionView.vue` is now tree-shaped: callers indent
their children. Callers default to collapsed.
- New caller detail page using `WorkflowGraph` to show direct children
only; the run summary's `WorkflowGraph` shows top-level callers and
their immediate descendants.
### Known trade-offs
- **Caller expansion runs inside the enclosing write transaction.**
`expandReusableWorkflowCaller` performs a git read of the called
workflow while holding the row locks that update the caller and insert
its children. This is intentional: the caller-row update and child-row
inserts must commit atomically. None of the call sites is hot (each
caller is expanded once per attempt), so the trade-off is acceptable.
- **A malformed `if:` expression on a job leaves it `Blocked`
silently.** `evaluateJobIf` now runs server-side as part of resolver
passes; deterministic expression errors (typos, undefined context
fields) are logged but do not surface in the UI. This is the same
behavior the resolver already had for concurrency-expression errors.
Distinguishing transient DB errors from user-authored expression errors
and writing the latter back as `StatusFailure` is a follow-up.

This PR introduces a new `ActionRunAttempt` model and makes Actions
execution attempt-scoped.
**Main Changes**
- Each workflow run trigger generates a new `ActionRunAttempt`. The
triggered jobs are then associated with this new `ActionRunAttempt`
record.
- Each rerun now creates:
- a new `ActionRunAttempt` record for the workflow run
- a full new set of `ActionRunJob` records for the new
`ActionRunAttempt`
- For jobs that need to be rerun, the new job records are created as
runnable jobs in the new attempt.
- For jobs that do not need to be rerun, new job records are still
created in the new attempt, but they reuse the result of the previous
attempt instead of executing again.
- Introduce `rerunPlan` to manage each rerun and refactored rerun flow
into a two-phase plan-based model:
- `buildRerunPlan`
- `execRerunPlan`
- `RerunFailedWorkflowRun` and `RerunFailed` no longer directly derives
all jobs that need to be rerun; this step is now handled by
`buildRerunPlan`.
- Converted artifacts from run-scoped to attempt-scoped:
- uploads are now associated with `RunAttemptID`
- listing, download, and deletion resolve against the current attempt
- Added attempt-aware web Actions views:
- the default run page shows the latest attempt
(`/actions/runs/{run_id}`)
- previous attempt pages show jobs and artifacts for that attempt
(`/actions/runs/{run_id}/attempts/{attempt_num}`)
- New APIs:
- `/repos/{owner}/{repo}/actions/runs/{run}/attempts/{attempt}`
- `/repos/{owner}/{repo}/actions/runs/{run}/attempts/{attempt}/jobs`
- New configuration `MAX_RERUN_ATTEMPTS`
- https://gitea.com/gitea/docs/pulls/383
**Compatibility**
- Existing legacy runs use `LatestAttemptID = 0` and legacy jobs use
`RunAttemptID = 0`. Therefore, these fields can be used to identify
legacy runs and jobs and provide backward compatibility.
- If a legacy run is rerun, an `ActionRunAttempt` with `attempt=1` will
be created to represent the original execution. Then a new
`ActionRunAttempt` with `attempt=2` will be created for the real rerun.
- Existing artifact records are not backfilled; legacy artifacts
continue to use `RunAttemptID = 0`.
**Improvements**
- It is now easier to inspect and download logs from previous attempts.
-
[`run_attempt`](https://docs.github.com/en/actions/reference/workflows-and-actions/contexts#github-context)
semantics are now aligned with GitHub.
- > A unique number for each attempt of a particular workflow run in a
repository. This number begins at 1 for the workflow run's first
attempt, and increments with each re-run.
- Rerun behavior is now clearer and more explicit.
- Instead of mutating the status of previous jobs in place, each rerun
creates a new attempt with a full new set of job records.
- Artifacts produced by different reruns can now be listed separately.

## Problem
Workflow-level concurrency groups were evaluated — and jobs were parsed
— before the run was persisted, so `run.ID` was `0` and `github.run_id`
in the expression context resolved to an empty string. Expressions like:
```yaml
concurrency:
group: ${{ github.workflow }}-${{ github.head_ref || github.run_id }}
cancel-in-progress: true
```
collapsed to `<workflow>-` on every push event (`head_ref` is empty on
push), so `cancel-in-progress` cancelled in-progress runs across
**unrelated branches**, not just the current one.
Reproduced on a 1.26 instance:
- push to `master` → `ci` run starts
- push to `feature-branch` → the `master` run gets cancelled
GitHub Actions' documented semantic: on push events `github.run_id` is
unique per run, so the group is unique → no cancellation; on PR events
`github.head_ref` is the source branch → cancellation is per-PR.
## Fix
Insert the run **before** parsing jobs or evaluating workflow-level
concurrency, so `run.ID` is populated in time for every expression that
reads `github.run_id` — not just the concurrency group, but also
`run-name`, job names, and `runs-on`.
`jobparser.Parse` now runs inside the `InsertRun` transaction, after
`db.Insert(ctx, run)`. Workflow-level concurrency evaluation runs next
and only mutates `run` in memory. All concurrency-derived fields
(`raw_concurrency`, `concurrency_group`, `concurrency_cancel`) plus
`status` and `title` are persisted in a single final `UpdateRun` at
end-of-transaction — one `INSERT` + one `UPDATE` per run in both the
concurrency and non-concurrency paths (matches pre-branch parity, one
fewer `UpdateRepoRunsNumbers` `COUNT` than the interim state).
`GenerateGiteaContext` now sets `run_id` from `run.ID` unconditionally;
every caller passes a persisted run.
**Verification**: tested end-to-end on a 1.26 deployment. Before the
patch, two successive `ci` pushes (one to master, one to a feature
branch) cross-cancelled each other. After the patch, the same pushes —
in both orders (master→branch, branch→master) — run to completion
simultaneously across 15+ runs with zero cancellations.
**Regression tests** in `services/actions/context_test.go`:
- `TestEvaluateRunConcurrency_RunIDFallback` — unit check that
`EvaluateRunConcurrencyFillModel` resolves `github.run_id` from
`run.ID`.
- `TestPrepareRunAndInsert_ExpressionsSeeRunID` — full-flow check: calls
`PrepareRunAndInsert` with `${{ github.run_id }}` in both `run-name` and
the concurrency group, then asserts the persisted `Title`,
`ConcurrencyGroup`, and `RawConcurrency` contain / survive the run's ID.
Re-ordering `db.Insert` relative to either parse or concurrency eval
fails this test.
## Relation to #37119
[#37119](https://github.com/go-gitea/gitea/pull/37119) also moves
concurrency evaluation into `InsertRun` but keeps it **before**
`db.Insert`, then tries to populate `run_id` only when `run.ID > 0` —
which is still `0` at that call site, so the cross-branch leak would
survive that PR as written. This PR fixes the ordering so that `run.ID`
is actually populated at eval time, and broadens it to cover parse-time
expression interpolation too.

Fixes: https://github.com/go-gitea/gitea/issues/36152
Enable the `nilnil` linter while adding `//nolint` comments to existing
violations. This will ensure no new issues enter the code base while we
can fix existing issues gradually.

Move the main logic of `generateTaskContext` and `findTaskNeeds` to the
`services` layer.
This is a part of #32751, since we need the git context and `needs` to
parse the concurrency expressions.
