I'm new to go and contributing to gitea, your guidance is much
appreciated.
This is meant to solve https://github.com/go-gitea/gitea/issues/13309
Previously, closed issues would not be shown under new issues in the
activity tab, even if they were newly created.
changes:
* Split out newlyCreatedIssues from issuesForActivityStatement to count
both currently open and closed issues.
* Use a seperate function to count active issues to prevent
double-counting issues after the above change.
Result is that new issues that have been closed are shown both under
"new" and "closed".

This PR split the `Board` into two parts. One is the struct has been
renamed to `Column` and the second we have a `Template Type`.
But to make it easier to review, this PR will not change the database
schemas, they are just renames. The database schema changes could be in
future PRs.

Before explaining the fix itself, lets look at the `action` table, and
how it is populated. Data is only ever inserted into it via
`activities_model.NotifyWatchers`, which will:
- Insert a row for each activity with `UserID` set to the acting user's
ID - this is the original activity, and is always inserted if anything
is to be inserted at all.
- It will insert a copy of each activity with the `UserID` set to the
repo's owner, if the owner is an Organization, and isn't the acting
user.
- It will insert a copy of each activity for every watcher of the repo,
as long as the watcher in question has read permission to the repo
unit the activity is about.
This means that if a repository belongs to an organizations, for most
activities, it will have at least two rows in the table. For
repositories watched by people other than their owner, an additional row
for each watcher.
These are useful duplicates, because they record which activities are
relevant for a particular user. However, for cases where we wish to see
the activities that happen around a repository, without limiting the
results to a particular user, we're *not* interested in the duplicates
stored for the watchers and the org. We only need the originals.
And this is what this change does: it introduces an additional option to
`GetFeedsOptions`: `OnlyPerformedByActor`. When this option is set,
`activities.GetFeeds()` will only return the original activities, where
the user id and the acting user id are the same. As these are *always*
inserted, we're not missing out on any activities. We're just getting
rid of the duplicates. As this is an additional `AND` condition, it can
never introduce items that would not have been included in the result
set before, it can only reduce, not extend.
These duplicates were only affecting call sites where `RequestedRepo`
was set, but `RequestedUser` and `RequestedTeam` were not. Both of those
call sites were updated to set `OnlyPerformedByActor`. As a result,
repository RSS feeds, and the `/repos/{owner}/{repo}/activities/feeds`
API end points no longer return dupes, only the original activities.
Rather than hardcoding this behaviour into `GetFeeds()` itself, I chose
to implement it as an explicit option, for the sake of clarity.

Many places have the following logic:
```go
func (jobs ActionJobList) GetRunIDs() []int64 {
ids := make(container.Set[int64], len(jobs))
for _, j := range jobs {
if j.RunID == 0 {
continue
}
ids.Add(j.RunID)
}
return ids.Values()
}
```
this introduces a `container.FilterMapUnique` function, which reduces
the code above to:
```go
func (jobs ActionJobList) GetRunIDs() []int64 {
return container.FilterMapUnique(jobs, func(j *ActionRunJob) (int64, bool) {
return j.RunID, j.RunID != 0
})
}
```

This solves two bugs. One bug is that due to the JOIN with the
`forgejo_blocked_users` table, duplicated users were generated if a user
had more than one user blocked, this lead to receiving more than one
entry in the actions table. The other bug is that if a user blocked more
than one user, it would still receive a action entry by a
blocked user, because the SQL query would not exclude the other
duplicated users that was generated by the JOIN.
The new solution is somewhat non-optimal in my eyes, but it's better
than rewriting the query to become a potential perfomance blocker (usage
of WHERE IN, which cannot be rewritten to a JOIN). It simply removes the
watchers after it was retrieved by the SQL query.

[MODERATION] Refactor integration testing (squash)
- Motivation for this PR is that I'd noticed that a lot of repeated
calls are happening between the test functions and that certain tests
weren't using helper functions like `GetCSRF`, therefor this refactor of
the integration tests to keep it: clean, small and hopefully more
maintainable and understandable.
- There are now three integration tests: `TestBlockUser`,
`TestBlockUserFromOrganization` and `TestBlockActions` (and has been
moved in that order in the source code).
- `TestBlockUser` is for doing blocking related actions as an user and
`TestBlockUserFromOrganization` as an organisation, even though they
execute the same kind of tests they do not share any database calls or
logic and therefor it currently doesn't make sense to merge them
together (hopefully such oppurtinutiy might be presented in the future).
- `TestBlockActions` now contain all tests for actions that should be
blocked after blocking has happened, most tests now share the same doer
and blocked users and a extra fixture has been added to make this
possible for the comment test.
- Less code, more comments and more re-use between tests.

## Purpose
This is a refactor toward building an abstraction over managing git
repositories.
Afterwards, it does not matter anymore if they are stored on the local
disk or somewhere remote.
## What this PR changes
We used `git.OpenRepository` everywhere previously.
Now, we should split them into two distinct functions:
Firstly, there are temporary repositories which do not change:
```go
git.OpenRepository(ctx, diskPath)
```
Gitea managed repositories having a record in the database in the
`repository` table are moved into the new package `gitrepo`:
```go
gitrepo.OpenRepository(ctx, repo_model.Repo)
```
Why is `repo_model.Repository` the second parameter instead of file
path?
Because then we can easily adapt our repository storage strategy.
The repositories can be stored locally, however, they could just as well
be stored on a remote server.
## Further changes in other PRs
- A Git Command wrapper on package `gitrepo` could be created. i.e.
`NewCommand(ctx, repo_model.Repository, commands...)`. `git.RunOpts{Dir:
repo.RepoPath()}`, the directory should be empty before invoking this
method and it can be filled in the function only. #28940
- Remove the `RepoPath()`/`WikiPath()` functions to reduce the
possibility of mistakes.

The steps to reproduce it.
First, create a new oauth2 source.
Then, a user login with this oauth2 source.
Disable the oauth2 source.
Visit users -> settings -> security, 500 will be displayed.
This is because this page only load active Oauth2 sources but not all
Oauth2 sources.

This PR touches functions used in templates. As templates are not static
typed, errors are harder to find, but I hope I catch it all. I think
some tests from other persons do not hurt.

To avoid deadlock problem, almost database related functions should be
have ctx as the first parameter.
This PR do a refactor for some of these functions.
Before, Gitea shows the database table stats on the `admin dashboard`
page.
It has some problems:
* `count(*)` is quite heavy. If tables have many records, this blocks
loading the admin page blocks for a long time
* Some users had even reported issues that they can't visit their admin
page because this page causes blocking or `50x error (reverse proxy
timeout)`
* The `actions` stat is not useful. The table is simply too large. Does
it really matter if it contains 1,000,000 rows or 9,999,999 rows?
* The translation `admin.dashboard.statistic_info` is difficult to
maintain.
So, this PR uses a separate page to show the stats and removes the
`actions` stat.
## ⚠️ BREAKING
The `actions` Prometheus metrics collector has been removed for the
reasons mentioned beforehand.
Please do not rely on its output anymore.
This PR replaces all string refName as a type `git.RefName` to make the
code more maintainable.
Fix#15367

It also fixed a bug that tags are not sync because `git remote --prune
origin` will not remove local tags if remote removed.
We in fact should use `git fetch --prune --tags origin` but not `git
remote update origin` to do the sync.
Some answer from ChatGPT as ref.
> If the git fetch --prune --tags command is not working as expected,
there could be a few reasons why. Here are a few things to check:
>
>Make sure that you have the latest version of Git installed on your
system. You can check the version by running git --version in your
terminal. If you have an outdated version, try updating Git and see if
that resolves the issue.
>
>Check that your Git repository is properly configured to track the
remote repository's tags. You can check this by running git config
--get-all remote.origin.fetch and verifying that it includes
+refs/tags/*:refs/tags/*. If it does not, you can add it by running git
config --add remote.origin.fetch "+refs/tags/*:refs/tags/*".
>
>Verify that the tags you are trying to prune actually exist on the
remote repository. You can do this by running git ls-remote --tags
origin to list all the tags on the remote repository.
>
>Check if any local tags have been created that match the names of tags
on the remote repository. If so, these local tags may be preventing the
git fetch --prune --tags command from working properly. You can delete
local tags using the git tag -d command.

activities from private organizations won't be shown even if the `Actor`
user is a member of the organization.
As mentioned in the issue, when using deploy key to make a commit and
push, the activity's `act_user_id` will be the id of the organization so
the activity won't be shown to non-admin users because the visibility of
the organization is private.
55a5717760/models/activities/action.go (L490-L503)
This PR improves this logic so the activities of private organizations
can be shown.
Replace #23350.
Refactor `setting.Database.UseMySQL` to
`setting.Database.Type.IsMySQL()`.
To avoid mismatching between `Type` and `UseXXX`.
This refactor can fix the bug mentioned in #23350, so it should be
backported.
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.
