* Reminder for no more logs to console (#22282)Jason Song2023-01-011-17/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | Even if the log mode is `file`, there are still few logs printed to the console at the very beginning. That's fine but confusing. Someone will think the console is the only place to find logs, and get nothing helpful. See https://github.com/go-gitea/gitea/issues/22274#issuecomment-1367917717. There should be a reminder that there are no more logs to the console. And to avoid log loss, we should add configured loggers first, then remove console logger if there's no `console` in the mode. Tests with `MODE = file`: Before: <img width="1792" alt="image" src="https://user-images.githubusercontent.com/9418365/210079862-d591677f-347e-46ed-a548-bb2ddbb0885c.png"> After: <img width="1792" alt="image" src="https://user-images.githubusercontent.com/9418365/210080002-d66cc418-6888-4909-b370-d03f5986ef41.png"> Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com> Co-authored-by: delvh <dev.lh@web.de>
* Fix bug of DisableGravatar default value (#22296)Lunny Xiao2023-01-011-1/+1
| | | | | | | #18058 made a mistake. The disableGravatar's default value depends on `OfflineMode`. If it's `true`, then `disableGravatar` is true, otherwise it's `false`. But not opposite. Co-authored-by: KN4CK3R <admin@oldschoolhack.me>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix #22270. Related to #18407. The old code treated both sitemap and sitemap index as the format like: ```xml ... <url> <loc>http://localhost:3000/explore/users/sitemap-1.xml</loc> </url> ... ``` Actually, it's incorrect for sitemap index, it should be: ```xml ... <sitemap> <loc>http://localhost:3000/explore/users/sitemap-1.xml</loc> </sitemap> ... ``` See https://www.sitemaps.org/protocol.html Co-authored-by: Lauris BH <lauris@nix.lv> Co-authored-by: delvh <dev.lh@web.de>
* Add `sync_on_commit` option for push mirrors api (#22271)Chongyi Zheng2022-12-301-0/+2

* Correctly handle select on multiple channels in Queues (#22146)zeripath2022-12-303-57/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a few places in FlushQueueWithContext which make an incorrect assumption about how `select` on multiple channels works. The problem is best expressed by looking at the following example: ```go package main import "fmt" func main() { closedChan := make(chan struct{}) close(closedChan) toClose := make(chan struct{}) count := 0 for { select { case <-closedChan: count++ fmt.Println(count) if count == 2 { close(toClose) } case <-toClose: return } } } ``` This PR double-checks that the contexts are closed outside of checking if there is data in the dataChan. It also rationalises the WorkerPool FlushWithContext because the previous implementation failed to handle pausing correctly.

* refactor auth interface to return error when verify failure (#22119)Lunny Xiao2022-12-282-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | This PR changed the Auth interface signature from `Verify(http *http.Request, w http.ResponseWriter, store DataStore, sess SessionStore) *user_model.User` to `Verify(http *http.Request, w http.ResponseWriter, store DataStore, sess SessionStore) (*user_model.User, error)`. There is a new return argument `error` which means the verification condition matched but verify process failed, we should stop the auth process. Before this PR, when return a `nil` user, we don't know the reason why it returned `nil`. If the match condition is not satisfied or it verified failure? For these two different results, we should have different handler. If the match condition is not satisfied, we should try next auth method and if there is no more auth method, it's an anonymous user. If the condition matched but verify failed, the auth process should be stop and return immediately.

* Add more test directory to exclude dir of air, remove watching templates ↵Lunny Xiao2022-12-271-1/+4
| | | | | | | | | | | | | | from air include dir because gitea has internal mechanism (#22246) Since #20218 introduced internal watching template, template watching should be removed from `air`. This will prevent restart the whole server once the template files changed to speed up developing when using `make watch`. To ensure `make watch` will reuse template watching, this PR introduced a new ENV `GITEA_RUN_MODE` to make sure `make watch` will always run in a dev mode of Gitea so that template watching will open. This PR also added more exclude testdata directories.

* Add setting to disable the git apply step in test patch (#22130)zeripath2022-12-191-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For a long time Gitea has tested PR patches using a git apply --check method, and in fact prior to the introduction of a read-tree assisted three-way merge in #18004, this was the only way of checking patches. Since #18004, the git apply --check method has been a fallback method, only used when the read-tree three-way merge method has detected a conflict. The read-tree assisted three-way merge method is much faster and less resource intensive method of detecting conflicts. #18004 kept the git apply method around because it was thought possible that this fallback might be able to rectify conflicts that the read-tree three-way merge detected. I am not certain if this could ever be the case. Given the uncertainty here and the now relative stability of the read-tree method - this PR makes using this fallback optional and disables it by default. The hope is that users will not notice any significant difference in conflict detection and we will be able to remove the git apply fallback in future, and/or improve the read-tree three-way merge method to catch any conflicts that git apply method might have been able to fix. An additional benefit is that patch checking should be significantly less resource intensive and much quicker.

* Ensure that plain files are rendered correctly even when containing ↵zeripath2022-12-171-1/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ambiguous characters (#22017) As recognised in #21841 the rendering of plain text files is somewhat incorrect when there are ambiguous characters as the html code is double escaped. In fact there are several more problems here. We have a residual isRenderedHTML which is actually simply escaping the file - not rendering it. This is badly named and gives the wrong impression. There is also unusual behaviour whether the file is called a Readme or not and there is no way to get to the source code if the file is called README. In reality what should happen is different depending on whether the file is being rendered a README at the bottom of the directory view or not. 1. If it is rendered as a README on a directory - it should simply be escaped and rendered as `<pre>` text. 2. If it is rendered as a file then it should be rendered as source code. This PR therefore does: 1. Rename IsRenderedHTML to IsPlainText 2. Readme files rendered at the bottom of the directory are rendered without line numbers 3. Otherwise plain text files are rendered as source code.

* Add doctor command for full GC of LFS (#21978)zeripath2022-12-151-0/+37
| | | | | | | | | | | | | | The recent PR adding orphaned checks to the LFS storage is not sufficient to completely GC LFS, as it is possible for LFSMetaObjects to remain associated with repos but still need to be garbage collected. Imagine a situation where a branch is uploaded containing LFS files but that branch is later completely deleted. The LFSMetaObjects will remain associated with the Repository but the Repository will no longer contain any pointers to the object. This PR adds a second doctor command to perform a full GC.

Normally a reupload is skipped because the database knows the blob is already present. The workaround checks if the blob exists on the file system.

* Prepend refs/heads/ to issue template refs (#20461)zeripath2022-11-222-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix #20456 At some point during the 1.17 cycle abbreviated refishs to issue branches started breaking. This is likely due serious inconsistencies in our management of refs throughout Gitea - which is a bug needing to be addressed in a different PR. (Likely more than one) We should try to use non-abbreviated `fullref`s as much as possible. That is where a user has inputted a abbreviated `refish` we should add `refs/heads/` if it is `branch` etc. I know people keep writing and merging PRs that remove prefixes from stored content but it is just wrong and it keeps causing problems like this. We should only remove the prefix at the time of presentation as the prefix is the only way of knowing umambiguously and permanently if the `ref` is referring to a `branch`, `tag` or `commit` / `SHA`. We need to make it so that every ref has the appropriate prefix, and probably also need to come up with some definitely unambiguous way of storing `SHA`s if they're used in a `ref` or `refish` field. We must not store a potentially ambiguous `refish` as a `ref`. (Especially when referring a `tag` - there is no reason why users cannot create a `branch` with the same short name as a `tag` and vice versa and any attempt to prevent this will fail. You can even create a `branch` and a `tag` that matches the `SHA` pattern.) To that end in order to fix this bug, when parsing issue templates check the provided `Ref` (here a `refish` because almost all users do not know or understand the subtly), if it does not start with `refs/` add the `BranchPrefix` to it. This allows people to make their templates refer to a `tag` but not to a `SHA` directly. (I don't think that is particularly unreasonable but if people disagree I can make the `refish` be checked to see if it matches the `SHA` pattern.) Next we need to handle the issue links that are already written. The links here are created with `git.RefURL` Here we see there is a bug introduced in #17551 whereby the provided `ref` argument can be double-escaped so we remove the incorrect external escape. (The escape added in #17551 is in the right place - unfortunately I missed that the calling function was doing the wrong thing.) Then within `RefURL()` we check if an unprefixed `ref` (therefore potentially a `refish`) matches the `SHA` pattern before assuming that is actually a `commit` - otherwise is assumed to be a `branch`. This will handle most of the problem cases excepting the very unusual cases where someone has deliberately written a `branch` to look like a `SHA1`. But please if something is called a `ref` or interpreted as a `ref` make it a full-ref before storing or using it. By all means if something is a `branch` assume the prefix is removed but always add it back in if you are using it as a `ref`. Stop storing abbreviated `branch` names and `tag` names - which are `refish` as a `ref`. It will keep on causing problems like this.

* Support comma-delimited string as labels in issue template (#21831)Jason Song2022-11-196-128/+354
| | | | | | | | | | | | | | | The [labels in issue YAML templates](https://docs.github.com/en/communities/using-templates-to-encourage-useful-issues-and-pull-requests/syntax-for-issue-forms#top-level-syntax) can be a string array or a comma-delimited string, so a single string should be valid labels. The old codes committed in #20987 ignore this, that's why the warning is displayed: <img width="618" alt="image" src="https://user-images.githubusercontent.com/9418365/202112642-93dc72d0-71c3-40a2-9720-30fc2d48c97c.png"> Fixes #17877.

| | | | | | | | | | | | | | | | | | | | | | Show which Chroma Lexer is used to highlight the file in the file header.
