## Changes
### 1. Handle reusable workflow expansion failures
If a reusable workflow caller job is invalid (e.g. uses a workflow with
syntax error), the job emitter should mark it as failed instead of
retrying.

### 2. No longer process concurrent run inline
**Before**: If a run(R1)'s status change unlocks another blocked run(R2)
via concurrency group, the job emitter will process R2 in R1's
transaction.
**Current**: No longer process R2 inline and emit the ID of R2 to let
another pass process it.
before: gitrepo vs git packages
after: git package fully handle all git operations
by the way, use `WithRepo(repo)` instead of `WithDir(repo.Path)` to hide
path details.
benefits:
1. remove all unnecessary wrappers, developers no need to struggle with
"which package should be used"
2. simplify code, RepositoryFacade can (will) be used everywhere, all
"path" details are (will be) hidden
## 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.
