Truncating file when creating RollingFileAppender? about plog HOT 3 CLOSED

Truncating a file you loses previous log entries. This is not good: imagine an application that crashed and restarted - all logged information is lost in such case.
What problem do you want to solve with truncation? Maybe there is an another solution?

Our logs tend to be transient -- they are only relevant for any given run of the program (we aren't using plog for a long-running daemon or server application or anything like that). When we run interactively, there's really no reason for us to save log messages from previous runs. When we run in batch, we save the logs to different directories, so this isn't an issue.

I realize this is probably very different than how others use this library. For our internal plog, I've added O_TRUNC to open() just to force this behavior. I was just wondering if you saw any value into having this option available upstream. Perhaps as a different Appender? If not, that's understandable, you can close this issue.

I see now. It makes sense in your case but it's not common. I'm closing the issue but thanks anyway!
