Re: [weewx-development] Re: Can Weewx '5' install on top of itself? (Explained below)

[Joel Bion]

I’d like to apologize for the somewhat scattered earlier email. Sent in a hurry, and not cleaned up. My question is based on my particular situation: I have a custom build of Linux, based on (but diverging from) a build-it-yourself model called Linux From Scratch.  I’ve also built a series of scripts to help me update packages and anything that directly or indirectly depends on the changed packages. It’s a bit of a hobby of mine that’s part of the backyard weather station hobby many of us enjoy. But a result of this is that packages will often get rebuilt and reinstalled after updates to packages they leverage happen. A great example of this is PHP, which leverages so many packages I’ve installed that it gets rebuilt once a month on average.  But…  I’ve  generally _not_ done that with Weewx, one of the few packages that I don’t rebuild in this routine matter. Why? Because WeeWX generates _real world data_. The entire rest of the system is in place _just_ so Weewx and a web server can run. I’ve been careful upgrading Weewx as I don’t want to make a mistake in “rebuilding the same version on top of itself” that corrupts or loses my weather data. I’ve also appreciated that Weewx has been self-contained - everything in /home/Weewx.  I am curious if that caution is still necessary and if I can reinstall version XYZ of Weewx on top an installation _already_ running XYZ. The kind replies to my earlier question answers this.

Do you mean 'pip' or 'apt' or 'yum' or 'rpm' specifically, and what do you mean by 'rebuilds' in your question ? yum has a 'reinstall' command apt-get has a --reinstall option pip has a --upgrade --force-reinstall option What exactly is your scenario and what are you concerned will be overwritten (or not overwritten) ? -- You received this message because you are subscribed to the Google Groups "weewx-development" group.
