Currently using the tip of main
(2c585d62a4) and when deleting a branch
(and presumably tag, but not tested), no workflows with `on: [delete]`
are being triggered. The runner isn't being notified about them. I see
this in the gitea log:
`2023/04/04 04:29:36 ...s/notifier_helper.go:102:Notify() [E] an error
occurred while executing the NotifyDeleteRef actions method:
gitRepo.GetCommit: object does not exist [id: test, rel_path: ]`
Understandably the ref has already been deleted and so `GetCommit`
fails. Currently at
https://github.com/go-gitea/gitea/blob/main/services/actions/notifier_helper.go#L130,
if the ref is an empty string it falls back to the default branch name.
This PR also checks if it is a `HookEventDelete` and does the same.
Currently `${{ github.ref }}` would be equivalent to the deleted branch
(if `notify()` succeded), but this PR allows `notify()` to proceed and
also aligns it with the GitHub Actions behavior at
https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#delete:
`$GITHUB_REF` / `${{ github.ref }}` => Default branch (main/master)
`$GITHUB_SHA` / `${{ github.sha }}` => Last commit on default branch
If the user needs the name of the deleted branch (or tag), it is
available as `${{ github.event.ref }}`.
There appears to be no way for the user to get the tip commit SHA of the
deleted branch (GitHub does not do this either).
N.B. there may be other conditions other than `HookEventDelete` where
the default branch ref needs swapped in, but this was sufficient for my
use case.
There is no fork concept in agit flow, anyone with read permission can
push `refs/for/<target-branch>/<topic-branch>` to the repo. So we should
treat it as a fork pull request because it may be from an untrusted
user.
When creating commit status for Actons jobs, a payload with nil
`HeadCommit` will cause panic.
Reported at:
https://gitea.com/gitea/act_runner/issues/28#issuecomment-732166
Although the `HeadCommit` probably can not be nil after #23215,
`CreateCommitStatus` should protect itself, to avoid being broken in the
future.
In addition, it's enough to print error log instead of returning err
when `CreateCommitStatus` failed.

To avoid duplicated load of the same data in an HTTP request, we can set
a context cache to do that. i.e. Some pages may load a user from a
database with the same id in different areas on the same page. But the
code is hidden in two different deep logic. How should we share the
user? As a result of this PR, now if both entry functions accept
`context.Context` as the first parameter and we just need to refactor
`GetUserByID` to reuse the user from the context cache. Then it will not
be loaded twice on an HTTP request.
But of course, sometimes we would like to reload an object from the
database, that's why `RemoveContextData` is also exposed.
The core context cache is here. It defines a new context
```go
type cacheContext struct {
ctx context.Context
data map[any]map[any]any
lock sync.RWMutex
}
var cacheContextKey = struct{}{}
func WithCacheContext(ctx context.Context) context.Context {
return context.WithValue(ctx, cacheContextKey, &cacheContext{
ctx: ctx,
data: make(map[any]map[any]any),
})
}
```
Then you can use the below 4 methods to read/write/del the data within
the same context.
```go
func GetContextData(ctx context.Context, tp, key any) any
func SetContextData(ctx context.Context, tp, key, value any)
func RemoveContextData(ctx context.Context, tp, key any)
func GetWithContextCache[T any](ctx context.Context, cacheGroupKey string, cacheTargetID any, f func() (T, error)) (T, error)
```
Then let's take a look at how `system.GetString` implement it.
```go
func GetSetting(ctx context.Context, key string) (string, error) {
return cache.GetWithContextCache(ctx, contextCacheKey, key, func() (string, error) {
return cache.GetString(genSettingCacheKey(key), func() (string, error) {
res, err := GetSettingNoCache(ctx, key)
if err != nil {
return "", err
}
return res.SettingValue, nil
})
})
}
```
First, it will check if context data include the setting object with the
key. If not, it will query from the global cache which may be memory or
a Redis cache. If not, it will get the object from the database. In the
end, if the object gets from the global cache or database, it will be
set into the context cache.
An object stored in the context cache will only be destroyed after the
context disappeared.
#21937 implemented only basic events based on name because of `act`'s
limitation. So I sent a PR to parse all possible events details in
https://gitea.com/gitea/act/pulls/11 and it merged. The ref
documentation is
https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows
This PR depends on that and make more detail responses for `push` events
and `pull_request` events. And it lefts more events there for future
PRs.
