Hey all, Summary: There's a script by jkroon in data/api.git (https://gitweb.gentoo.org/data/api.git/) that prints the next available UID/GID pair for new acct-* packages. You can use it by: cd ~/git/gentoo/data/api git pull sh bin/used_free_uidgids.sh The outcome looks like this for those curious: https://dev.gentoo.org/~juippis/pics/free_uid_gid_by_jkroon.png Check the Author e-mail from the script to report bugs, and please open pull requests here: https://github.com/gentoo/api-gentoo-org
Story: As someone who's pushed a few new UID/GID packages lately it was becoming more and more tedious trying to find the next free number. And I was personally becoming worried when we're going to run out of available IDs. Now a while back I asked half-jokingly someone to write a script that finds the next free UID, GID and UID/GID, and also prints the current number of free IDs <500 in #gentoo-dev IRC channel. Lucky for us all, jkroon was up to the task. I wanted the implementation to be "open for inspection" and available in every system syncing data/api.git. So in my eyes the viable options were using bash or python, and the current script is written in bash. We've heard enough about using bash for this so please leave such comments out from this thread. It is well documented and should be maintainable for the time being, but if someone is up to re-writing it using some other viable language (python), please go ahead! In its current state the script works and is very useful! Script's output looks like this: #ID UID GID ... 317..320 FREE FREE 321 USED USED 322..326 FREE FREE 327..330 USED USED 331..332 USED FREE 333..372 USED USED 373 USED FREE ... Recommended GID only: 460 Recommended UID only: 458 Recommended UID+GID both: 326 Free UIDs: 200 Free GIDs: 177 (note that FREE/USED are colourcoded for your convenience, check the screenshot above!) It is not forbidden to mix and mash UID/GID between different packages, but I'd still suggest to find a new "pair" even if you push just an UID or GID. Since we don't seem to be in danger of running out any time soon. Please report bugs to Author (e-mail in the script), and for any fixes open pull requests at https://github.com/gentoo/api-gentoo-org/ Not to any proxied maintainers (reading this far), a free UID/GID pair will be given to you when your acct-* packages are merged, so you don't have to reserve an ID beforehand. But it'd be great if you picked one that is free when making your new acct-* packages so at least during merge the next free one will be close to your chosen one. Enjoy everyone, and huge thanks to jkroon! -- juippis
