Is there a way to stop attaching to a process when using "-o" option

[EricLin89]

I used command memray attach <pid> -o <output.bin> to analyze the process's memory allocation.
After gathering enough data, I would like to stop the attachment, because otherwise the output file would eventually consume all my disk space.
But I can't find a way to do this other than stopping the process, which I would rather avoid.
Deleting the output file doesn't work because the file handler is still occupied by the process and the disk won't be freed until the file is closed.

We're working on adding a command to do this right now in #458, so keep an eye out for our next release.

But I can't find a way to do this other than stopping the process, which I would rather avoid.

In the meantime, calling memray attach a second time happens to gracefully stop the tracking that was started by a previous call to memray attach, so a hacky way to get what you want with the current Memray version is to re-attach without an output file, stopping tracking to the file and starting tracking with the live-mode TUI - which you can then just quit out of by pressing q and all the tracking will be stopped.

If you can't use the TUI because you're in an headless environment with no terminal, you could re-attach and specify an invalid file path as the output file, something like memray attach <pid> -o / — that will fail and print an error (because / isn't a valid output file), but it will detach the old tracker before it fails.
