Hey all, |

Summary: |
| 4 |
There's a script by jkroon in data/api.git |
| 5 |
(https://gitweb.gentoo.org/data/api.git/) that prints the next available |
| 6 |
UID/GID pair for new acct-* packages. You can use it by: |
| 7 |
cd ~/git/gentoo/data/api |
| 8 |
git pull |
| 9 |
sh bin/used_free_uidgids.sh |
| 10 |
|
| 11 |
The outcome looks like this for those curious: |

Story: |
| 19 |
As someone who's pushed a few new UID/GID packages lately it was |
| 20 |
becoming more and more tedious trying to find the next free number. And |
| 21 |
I was personally becoming worried when we're going to run out of |
| 22 |
available IDs. |
| 23 |
|
| 24 |
Now a while back I asked half-jokingly someone to write a script that |
| 25 |
finds the next free UID, GID and UID/GID, and also prints the current |
| 26 |
number of free IDs <500 in #gentoo-dev IRC channel. Lucky for us all, |
| 27 |
jkroon was up to the task. |
| 28 |
|
| 29 |
I wanted the implementation to be "open for inspection" and available in |
| 30 |
every system syncing data/api.git. So in my eyes the viable options were |
| 31 |
using bash or python, and the current script is written in bash. We've |
| 32 |
heard enough about using bash for this so please leave such comments out |
| 33 |
from this thread. It is well documented and should be maintainable for |
| 34 |
the time being, but if someone is up to re-writing it using some other |
| 35 |
viable language (python), please go ahead! In its current state the |
| 36 |
script works and is very useful! |
| 37 |
|
| 38 |
Script's output looks like this: |
| 39 |
#ID UID GID |
| 40 |
... |
| 41 |
317..320 FREE FREE |
| 42 |
321 USED USED |
| 43 |
322..326 FREE FREE |
| 44 |
327..330 USED USED |
| 45 |
331..332 USED FREE |
| 46 |
333..372 USED USED |
| 47 |
373 USED FREE |
| 48 |
... |
| 49 |
|
| 50 |
Recommended GID only: 460 |
| 51 |
Recommended UID only: 458 |
| 52 |
Recommended UID+GID both: 326 |
| 53 |
Free UIDs: 200 |
| 54 |
Free GIDs: 177 |
| 55 |
|
| 56 |
(note that FREE/USED are colourcoded for your convenience, check the |
| 57 |
screenshot above!) |
| 58 |
|
| 59 |
It is not forbidden to mix and mash UID/GID between different packages, |
| 60 |
but I'd still suggest to find a new "pair" even if you push just an UID |
| 61 |
or GID. Since we don't seem to be in danger of running out any time soon. |
| 62 |
|
| 63 |
Please report bugs to Author (e-mail in the script), and for any fixes |
| 64 |
open pull requests at https://github.com/gentoo/api-gentoo-org/ |
| 65 |
|
| 66 |
Not to any proxied maintainers (reading this far), a free UID/GID pair |
| 67 |
will be given to you when your acct-* packages are merged, so you don't |
| 68 |
have to reserve an ID beforehand. But it'd be great if you picked one |
| 69 |
that is free when making your new acct-* packages so at least during |
| 70 |
merge the next free one will be close to your chosen one. |
| 71 |
|
| 72 |
Enjoy everyone, and huge thanks to jkroon! |
