Beginning since 2af30f715e, Gitea has a
500 error when visiting a user profile with `?tab=overview` in the URL
when the user doesn't have a `.profile/README.md`, because the backend
code assumes that if the tab is overview a profile repository must
exist, and checks that the repository is nil aren't done.
In this PR I treat `?tab=overview` the same as if no tab is set in the
URL, which corrects this behaviour- Now, when visiting `?tab=overview`,
if `.profile/README.md` exists on that user's profile it'll show that as
it should, otherwise it'll show the repositories tab.

This PR adds the ability to ignore revisions specified in the
`.git-blame-ignore-revs` file in the root of the repository.
The banner is displayed in this case. I intentionally did not add a UI
way to bypass the ignore file (same behaviour as Github) but you can add
`?bypass-blame-ignore=true` to the url manually.

Most middleware throw a 404 in case something is not found e.g. a Repo
that is not existing. But most API endpoints don't include the 404
response in their documentation. This PR changes this.
Unfortunately, when a system setting hasn't been stored in the database,
it cannot be cached.
Meanwhile, this PR also uses context cache for push email avatar display
which should avoid to read user table via email address again and again.
According to my local test, this should reduce dashboard elapsed time
from 150ms -> 80ms .
This feature was removed by #22219 to avoid possible CSRF attack.
This PR takes reverseproxy auth for API back but with default disabled.
To prevent possbile CSRF attack, the responsibility will be the
reverseproxy but not Gitea itself.
For those want to enable this `ENABLE_REVERSE_PROXY_AUTHENTICATION_API`,
they should know what they are doing.

Currently, Artifact does not have an expiration and automatic cleanup
mechanism, and this feature needs to be added. It contains the following
key points:
- [x] add global artifact retention days option in config file. Default
value is 90 days.
- [x] add cron task to clean up expired artifacts. It should run once a
day.
- [x] support custom retention period from `retention-days: 5` in
`upload-artifact@v3`.
- [x] artifacts link in actions view should be non-clickable text when
expired.
They currently throw a Internal Server Error when you use them without a
token. Now they correctly return a `token is required` error.
This is no security issue. If you use this endpoints with a token that
don't have the correct permission, you get the correct error. This is
not affected by this PR.

Cargo registry-auth feature requires config.json to have a property
auth-required set to true in order to send token to all registry
requests.
This is ok for git index because you can manually edit the config.json
file to add the auth-required, but when using sparse
(setting index url to
"sparse+https://git.example.com/api/packages/{owner}/cargo/"), the
config.json is dynamically rendered, and does not reflect changes to the
config.json file in the repo.
I see two approaches:
- Serve the real config.json file when fetching the config.json on the
cargo service.
- Automatically detect if the registry requires authorization. (This is
what I implemented in this PR).
What the PR does:
- When a cargo index repository is created, on the config.json, set
auth-required to wether or not the repository is private.
- When the cargo/config.json endpoint is called, set auth-required to
wether or not the request was authorized using an API token.
According to the GitHub API Spec:
https://docs.github.com/en/rest/actions/secrets?apiVersion=2022-11-28#create-or-update-an-organization-secret
Merge the Create and Update secret into a single API.
- Remove the `CreateSecretOption` struct and replace it with
`CreateOrUpdateSecretOption` in `modules/structs/secret.go`
- Update the `CreateOrUpdateOrgSecret` function in

instead of `UpdateSecretOption`
- Remove the `CreateOrgSecret` function in
`routers/api/v1/org/action.go` and replace it with
`CreateOrUpdateOrgSecret`
- Update the Swagger documentation in
`routers/api/v1/swagger/options.go` and `templates/swagger/v1_json.tmpl`
to reflect the changes in the struct names and function names

The web context (modules/context.Context) is quite complex, it's
difficult for the callers to initialize correctly.
This PR introduces a `NewWebContext` function, to make sure the web
context have the same behavior for different cases.
Fixes: #26333.
Previously, this endpoint only updates the `StatusCheckContexts` field
when `EnableStatusCheck==true`, which makes it impossible to clear the
array otherwise.
This patch uses slice `nil`-ness to decide whether to update the list of
checks. The field is ignored when either the client explicitly passes in
a null, or just omits the field from the json ([which causes
`json.Unmarshal` to leave the struct field
unchanged](https://go.dev/play/p/Z2XHOILuB1Q)). I think this is a better
measure of intent than whether the `EnableStatusCheck` flag was set,
because it matches the semantics of other field types.
Also adds a test case. I noticed that [`testAPIEditBranchProtection`
only checks the branch
name](c1c83dbaec/tests/integration/api_branch_test.go (L68))
and no other fields, so I added some extra `GET` calls and specific
checks to make sure the fields are changing properly.
I added those checks the existing integration test; is that the right
place for it?
This PR has multiple parts, and I didn't split them because
it's not easy to test them separately since they are all about the
dashboard page for issues.
1. Support counting issues via indexer to fix #26361
2. Fix repo selection so it also fixes #26653
3. Keep keywords in filter links.
The first two are regressions of #26012.

## Archived labels
This adds the structure to allow for archived labels.
Archived labels are, just like closed milestones or projects, a medium to hide information without deleting it.
It is especially useful if there are outdated labels that should no longer be used without deleting the label entirely.
## Changes
1. UI and API have been equipped with the support to mark a label as archived
2. The time when a label has been archived will be stored in the DB
## Outsourced for the future
There's no special handling for archived labels at the moment.
This will be done in the future.

This PR is an extended implementation of #25189 and builds upon the
proposal by @hickford in #25653, utilizing some ideas proposed
internally by @wxiaoguang.
Mainly, this PR consists of a mechanism to pre-register OAuth2
applications on startup, which can be enabled or disabled by modifying
the `[oauth2].DEFAULT_APPLICATIONS` parameter in app.ini. The OAuth2
applications registered this way are being marked as "locked" and
neither be deleted nor edited over UI to prevent confusing/unexpected
behavior. Instead, they're being removed if no longer enabled in config.
The implemented mechanism can also be used to pre-register other OAuth2
applications in the future, if wanted.

There are 2 kinds of ".Editorconfig" in code, one is `JSON string` for

This PR distinguish them with different names.
And by the way, change the default tab size from 8 to 4, I think few
people would like to use 8-size tabs nowadays.
Before:
* `{{.locale.Tr ...}}`
* `{{$.locale.Tr ...}}`
* `{{$.root.locale.Tr ...}}`
* `{{template "sub" .}}`
* `{{template "sub" (dict "locale" $.locale)}}`
* `{{template "sub" (dict "root" $)}}`
* .....
With context function: only need to `{{ctx.Locale.Tr ...}}`
The "ctx" could be considered as a super-global variable for all
templates including sub-templates.
To avoid potential risks (any bug in the template context function
package), this PR only starts using "ctx" in "head.tmpl" and
"footer.tmpl" and it has a "DataRaceCheck". If there is anything wrong,
the code can be fixed or reverted easily.
Until now expired package data gets deleted daily by a cronjob. The
admin page shows the size of all packages and the size of unreferenced
data. The users (#25035, #20631) expect the deletion of this data if
they run the cronjob from the admin page but the job only deletes data
older than 24h.
This PR adds a new button which deletes all expired data.

Fix #24662.
Replace #24822 and #25708 (although it has been merged)
## Background
In the past, Gitea supported issue searching with a keyword and
conditions in a less efficient way. It worked by searching for issues
with the keyword and obtaining limited IDs (as it is heavy to get all)
on the indexer (bleve/elasticsearch/meilisearch), and then querying with
conditions on the database to find a subset of the found IDs. This is
why the results could be incomplete.
To solve this issue, we need to store all fields that could be used as
conditions in the indexer and support both keyword and additional
conditions when searching with the indexer.
## Major changes
- Redefine `IndexerData` to include all fields that could be used as
filter conditions.
- Refactor `Search(ctx context.Context, kw string, repoIDs []int64,
limit, start int, state string)` to `Search(ctx context.Context, options
*SearchOptions)`, so it supports more conditions now.
- Change the data type stored in `issueIndexerQueue`. Use
`IndexerMetadata` instead of `IndexerData` in case the data has been
updated while it is in the queue. This also reduces the storage size of
the queue.
- Enhance searching with Bleve/Elasticsearch/Meilisearch, make them
fully support `SearchOptions`. Also, update the data versions.
- Keep most logic of database indexer, but remove
`issues.SearchIssueIDsByKeyword` in `models` to avoid confusion where is
the entry point to search issues.
- Start a Meilisearch instance to test it in unit tests.
- Add unit tests with almost full coverage to test
Bleve/Elasticsearch/Meilisearch indexer.

In the original implementation, we can only get the first 30 records of
the commit status (the default paging size), if the commit status is
more than 30, it will lead to the bug #25990. I made the following two
changes.
- On the page, use the ` db.ListOptions{ListAll: true}` parameter
instead of `db.ListOptions{}`
- The `GetLatestCommitStatus` function makes a determination as to
whether or not a pager is being used.

Add `ignoreGlobal` parameter to `reqUnitAccess` and only check global

This PR addresses an issue where logged-in users get redirected to the
homepage when trying to access a URL with the redirect_to parameter. The
issue was traced back to a middleware function in
services/auth/middleware.go that redirects logged-in users to the
homepage. This function didn't account the redirect_to parameter.
The fix modifies the middleware function to check for this case and
redirect the user to the specified URL instead of the homepage.

Remove "StaticRootPath" on the admin config display page, because few
end user really need it, it only causes misconfiguration.

Before: the concept "Content string" is used everywhere. It has some
problems:
1. Sometimes it means "base64 encoded content", sometimes it means "raw
binary content"
2. It doesn't work with large files, eg: uploading a 1G LFS file would
make Gitea process OOM
This PR does the refactoring: use "ContentReader" / "ContentBase64"
instead of "Content"
This PR is not breaking because the key in API JSON is still "content":
`` ContentBase64 string `json:"content"` ``
