[SOLVED] Update & Install Size

Czarcasmo · 2011-06-09 02:49:33

Hi all.

Forgive the idiotic question, but when I -Syu my system and it displays the installed size on my hard drive, is that *new* space that's being used or are the packages that are being updated being overwritten? In theory that would make it possible to have a neutral or small gain/loss as opposed to the large numbers I frequently see when I update. Hopefully that question made sense.

Thanks for the help; this is a great community.

Czar.

It's the install size of the new packages and does not take into account of what's being removed. This has been brought up here before with no final solution that I'm aware of. It's a bit tricky to search for, so it's understandable that you didn't find an answer.

If you look in /var/cache/pacman/pkg/ you will see that packages are not overwritten - this allows you to downgrade a package if necessary...

Of course. I was thinking of upgrade/replace and not total disc size.

Hey guys,

Thank you both for the quick reply. I'm assuming that what is kept in /var/cache/pacman/pkg/ is simply one version back, not an entire version history, yes? That could be real hell on my laptop in six months.

Thanks,
Czar.

EDIT: Just checked myself on a test machine I have in my lab. It seems to keep...well...everything. I'm assuming there's no easy way to keep this 'clean'?

No. Arch expects you to manage your own system. There are a couple of pacman flags that can help. Reading pacman's man page is very helpful for understanding the options.

Read man pacman and look for -Sc and -Scc (cache clean).

Everything is kept until you do a 'pacman -Sc' or 'pacman -Scc'
Check man pacman for details

Thanks everyone for the quick replies AND (too boolean?) not out-and-out telling me to RTFM.

Cheers,
Czar.

skottish tosses warm tortilla at fist. Rock-paper-scissors become ingredients for tacos. Czarcasmo eats well today.

Tortilla? WTF!? Isn't that some sort of limp taco?

It's somewhat related to https://bugs.archlinux.org/task/12566

sand_man · 2011-06-09 10:46:49

There's this script --> https://bbs.archlinux.org/viewtopic.php?id=9104 , which let's you have better control over which packages to keep in the cache. I have never tried it myself, so can't say how well it works.

Or a more recent one: http://aur.archlinux.org/packages.php?ID=41918

FYI, the next release of pacman will have 'net upgrade size' listed for any sync operation that updates a package:

# pacman -Su
Password: 
:: Starting full system upgrade...
warning: make: ignoring package upgrade (3.81-5 => 3.82-3)
warning: qemu: ignoring package upgrade (0.13.0-1 => 0.14.1-1)
resolving dependencies...
looking for inter-conflicts...

Targets (1):

Name  Old Version  New Version         Size

qt    4.7.3-2      4.7.3-3        24.59 MiB

Total Download Size:    24.59 MiB
Total Installed Size:   98.12 MiB
Net Upgrade Size:       -6.77 MiB

Proceed with installation? [Y/n]

@falconindy
I've seem http://mailman.archlinux.org/pipermail/ … 13211.html patch, but https://bugs.archlinux.org/task/12566 it's not yet marked as solved. According to the ML post, it should work for upgrade (-U) operations too.
Just to be sure: 'Net Upgrade Size: -6.77 MiB' means the new version has the installed size over 6 MB smaller than the old version and it doesn't take the Download Size into account, right?

falconindy · 2011-06-09 16:17:22

Correct. It's the net change in hard disk usage after the transaction.
