wxiaoguang	0d54395fb5	Improve logger Pause handling (#24946) ... The old EventWriter's Run does: ```go for { handlePause() select { case event <- Queue: write the log event ... } } ``` So, if an event writer is started before the logger is paused, there is a chance that the logger isn't paused for the first message. The new logic is: ```go for { select { case event <- Queue: handlePause() write the log event ... } } ``` Then the event writer can be correctly paused	1 year ago
wxiaoguang	7314726bab	Do not output "Trace" level logs from process manager by default (#24952) ... The old process manager's `Trace` function by default calls `log.Printf` to output "trace" level logs. That's not ideal because by default the trace level logs should not be outputted. In history it didn't cause problems because there was no other call to the process manager before the logger system's initialization. But if there is any package using the process manager before the "Trace" function gets assigned to the logger system's trace function, the process manager will outputs unexpected verbose messages, this behavior is not expected in most cases. Now, the logger system also uses process manager to manage its goroutine contexts, so it's the time to fix the old "trace" behavior: by default, do not output the trace level messages.

wxiaoguang	18f26cfbf7	Improve queue and logger context (#24924) ... Before there was a "graceful function": RunWithShutdownFns, it's mainly for some modules which doesn't support context. The old queue system doesn't work well with context, so the old queues need it. After the queue refactoring, the new queue works with context well, so, use Golang context as much as possible, the `RunWithShutdownFns` could be removed (replaced by RunWithCancel for context cancel mechanism), the related code could be simplified. This PR also fixes some legacy queue-init problems, eg: * typo : archiver: "unable to create codes indexer queue" => "unable to create repo-archive queue" * no nil check for failed queues, which causes unfriendly panic After this PR, many goroutines could have better display name:  	2 years ago
wxiaoguang	4647660776	Rewrite logger system (#24726) ... ## ⚠️ Breaking The `log.<mode>.<logger>` style config has been dropped. If you used it, please check the new config manual & app.example.ini to make your instance output logs as expected. Although many legacy options still work, it's encouraged to upgrade to the new options. The SMTP logger is deleted because SMTP is not suitable to collect logs. If you have manually configured Gitea log options, please confirm the logger system works as expected after upgrading. ## Description Close #12082 and maybe more log-related issues, resolve some related FIXMEs in old code (which seems unfixable before) Just like rewriting queue #24505 : make code maintainable, clear legacy bugs, and add the ability to support more writers (eg: JSON, structured log) There is a new document (with examples): `logging-config.en-us.md` This PR is safer than the queue rewriting, because it's just for logging, it won't break other logic. ## The old problems The logging system is quite old and difficult to maintain: * Unclear concepts: Logger, NamedLogger, MultiChannelledLogger, SubLogger, EventLogger, WriterLogger etc * Some code is diffuclt to konw whether it is right: `log.DelNamedLogger("console")` vs `log.DelNamedLogger(log.DEFAULT)` vs `log.DelLogger("console")` * The old system heavily depends on ini config system, it's difficult to create new logger for different purpose, and it's very fragile. * The "color" trick is difficult to use and read, many colors are unnecessary, and in the future structured log could help * It's difficult to add other log formats, eg: JSON format * The log outputer doesn't have full control of its goroutine, it's difficult to make outputer have advanced behaviors * The logs could be lost in some cases: eg: no Fatal error when using CLI. * Config options are passed by JSON, which is quite fragile. * INI package makes the KEY in `[log]` section visible in `[log.sub1]` and `[log.sub1.subA]`, this behavior is quite fragile and would cause more unclear problems, and there is no strong requirement to support `log.<mode>.<logger>` syntax. ## The new design See `logger.go` for documents. ## Screenshot <details>    </details> ## TODO * [x] add some new tests * [x] fix some tests * [x] test some sub-commands (manually ....) --------- Co-authored-by: Jason Song <i@wolfogre.com> Co-authored-by: delvh <dev.lh@web.de> Co-authored-by: Giteabot <teabot@gitea.io>	2 years ago
