silverwind	e24f651c86	Add template linting via djlint (#25212) ... So I found this [linter](https://github.com/Riverside-Healthcare/djlint) which features a mode for go templates, so I gave it a try and it did find a number of valid issue, like unbalanced tags etc. It also has a number of bugs, I had to disable/workaround many issues. Given that this linter is written in python, this does add a dependency on `python` >= 3.8 and `poetry` to the development environment to be able to run this linter locally. - `e.g.` prefixes on placeholders are removed because the linter had a false-positive on `placeholder="e.g. cn=Search"` for the `attr=value` syntax and it's not ideal anyways to write `e.g.` into a placeholder because a placeholder is meant to hold a sample value. - In `templates/repo/settings/options.tmpl` I simplified the logic to not conditionally create opening tags without closing tags because this stuff confuses the linter (and possibly the reader as well).	1 year ago
wxiaoguang	58dfaf3a75	Improve queue & process & stacktrace (#24636) ... Although some features are mixed together in this PR, this PR is not that large, and these features are all related. Actually there are more than 70 lines are for a toy "test queue", so this PR is quite simple. Major features: 1. Allow site admin to clear a queue (remove all items in a queue) * Because there is no transaction, the "unique queue" could be corrupted in rare cases, that's unfixable. * eg: the item is in the "set" but not in the "list", so the item would never be able to be pushed into the queue. * Now site admin could simply clear the queue, then everything becomes correct, the lost items could be re-pushed into queue by future operations. 3. Split the "admin/monitor" to separate pages 4. Allow to download diagnosis report * In history, there were many users reporting that Gitea queue gets stuck, or Gitea's CPU is 100% * With diagnosis report, maintainers could know what happens clearly The diagnosis report sample: [gitea-diagnosis-20230510-192913.zip](https://github.com/go-gitea/gitea/files/11441346/gitea-diagnosis-20230510-192913.zip) , use "go tool pprof profile.dat" to view the report.

wxiaoguang	6f9c278559	Rewrite queue (#24505) ... # ⚠️ Breaking Many deprecated queue config options are removed (actually, they should have been removed in 1.18/1.19). If you see the fatal message when starting Gitea: "Please update your app.ini to remove deprecated config options", please follow the error messages to remove these options from your app.ini. Example: ``` 2023/05/06 19:39:22 [E] Removed queue option: `[indexer].ISSUE_INDEXER_QUEUE_TYPE`. Use new options in `[queue.issue_indexer]` 2023/05/06 19:39:22 [E] Removed queue option: `[indexer].UPDATE_BUFFER_LEN`. Use new options in `[queue.issue_indexer]` 2023/05/06 19:39:22 [F] Please update your app.ini to remove deprecated config options ``` Many options in `[queue]` are are dropped, including: `WRAP_IF_NECESSARY`, `MAX_ATTEMPTS`, `TIMEOUT`, `WORKERS`, `BLOCK_TIMEOUT`, `BOOST_TIMEOUT`, `BOOST_WORKERS`, they can be removed from app.ini. # The problem The old queue package has some legacy problems: * complexity: I doubt few people could tell how it works. * maintainability: Too many channels and mutex/cond are mixed together, too many different structs/interfaces depends each other. * stability: due to the complexity & maintainability, sometimes there are strange bugs and difficult to debug, and some code doesn't have test (indeed some code is difficult to test because a lot of things are mixed together). * general applicability: although it is called "queue", its behavior is not a well-known queue. * scalability: it doesn't seem easy to make it work with a cluster without breaking its behaviors. It came from some very old code to "avoid breaking", however, its technical debt is too heavy now. It's a good time to introduce a better "queue" package. # The new queue package It keeps using old config and concept as much as possible. * It only contains two major kinds of concepts: * The "base queue": channel, levelqueue, redis * They have the same abstraction, the same interface, and they are tested by the same testing code. * The "WokerPoolQueue", it uses the "base queue" to provide "worker pool" function, calls the "handler" to process the data in the base queue. * The new code doesn't do "PushBack" * Think about a queue with many workers, the "PushBack" can't guarantee the order for re-queued unhandled items, so in new code it just does "normal push" * The new code doesn't do "pause/resume" * The "pause/resume" was designed to handle some handler's failure: eg: document indexer (elasticsearch) is down * If a queue is paused for long time, either the producers blocks or the new items are dropped. * The new code doesn't do such "pause/resume" trick, it's not a common queue's behavior and it doesn't help much. * If there are unhandled items, the "push" function just blocks for a few seconds and then re-queue them and retry. * The new code doesn't do "worker booster" * Gitea's queue's handlers are light functions, the cost is only the go-routine, so it doesn't make sense to "boost" them. * The new code only use "max worker number" to limit the concurrent workers. * The new "Push" never blocks forever * Instead of creating more and more blocking goroutines, return an error is more friendly to the server and to the end user. There are more details in code comments: eg: the "Flush" problem, the strange "code.index" hanging problem, the "immediate" queue problem. Almost ready for review. TODO: * [x] add some necessary comments during review * [x] add some more tests if necessary * [x] update documents and config options * [x] test max worker / active worker * [x] re-run the CI tasks to see whether any test is flaky * [x] improve the `handleOldLengthConfiguration` to provide more friendly messages * [x] fine tune default config values (eg: length?) ## Code coverage: 	2 years ago
