Enabling or disabling per-thread logging at runtime from the monitor causes unexpected results. +Steps to reproduce: +Enabling per-thread logging at runtime: + +1. Start QEMU : `./qemu-system-x86_64 -S -monitor stdio -D qemu.log.%d` +2. Enable per-thread logging from the HMP monitor : `(qemu) log tid` +3. Fails with `Filename template with '%d' required for 'tid'` even though such a template was passed with `-D`. + +Disabling per-thread logging at runtime: + +1. Start QEMU : `./qemu-system-x86_64 -S -monitor stdio -D qemu.log.%d -d tid,cpu_reset` +2. Disable per-thread logging from the HMP monitor: `(qemu) log cpu_reset` +3. QEMU creates a log file with a bogus `qemu.log.%d` name. +Additional information: +[Series](https://patchew.org/QEMU/20221104120059.678470-1-groug@kaod.org/) posted and already reviewed by @rth7680 . |
