[GitHub] [apisix] kizy008 opened a new issue, #7899: help request: [file-logger] duplicate log, new log file contains history log message

kizy008 opened a new issue, #7899:
URL: https://github.com/apache/apisix/issues/7899

   ### Description
   
   In my project, I need split log file by hour and delete logs 7 days ago. So I write a rotate plugin like [log-rotate.lua], and it works.
   But I found that every new log file contains the history log message. For example, [log-2022-09-01_01-00-00.log] contains all message in [log-2022-09-01_00-00-00.log]]. So every log contains all history message.  I think the new log should contains message in its hour period. But I got all history message. 
   I want to know how to get incremental logs in new log file.
   
   我的项目中需要将日志按照小时分割并自动淘汰7天前的历史日志。 所以我仿照[log-rotate.lua]写了file-logger的滚动切割日志插件，并且按照预期生效了。但是我发现，所有的心日志文件都包含了全量的历史日志。比如 [log-2022-09-01_01-00-00.log]日志不仅包含了23点到0点的日志， 还包含了所有的历史全量日志。我本以为新日志应该只包含过去1个小时之内的日志。
   我想知道如何利用file-logger在每个日志文件中保存这个小时时间段内增量的日志呢？
   
   ### Environment
   
   - APISIX version (run `apisix version`):
   - Operating system (run `uname -a`):
   - OpenResty / Nginx version (run `openresty -V` or `nginx -V`):
   - etcd version, if relevant (run `curl http://127.0.0.1:9090/v1/server_info`):
   - APISIX Dashboard version, if relevant:
   - Plugin runner version, for issues related to plugin runners:
   - LuaRocks version, for installation issues (run `luarocks --version`):

   1. rename old log file and create new one
   2. notify other processes to reopen the file
   Do you follow the two steps ?

   You could use [ngxsharedict](https://github.com/openresty/lua-nginx-module#ngxshareddict) to notify other processes.
   For example
   
   ```
   -- process 1
   local rotate = ngx.shared.rotate
   rotate:set("reopen", true)
   ```
   
   ```
   -- process 2
   local rotate = ngx.shared.rotate
   local reopen = rotate:get("reopen")
   if reopen then
       -- reopen file
   end
   ```

   Since this is your own code, not related to the project, I turned it into discussion.
