Package managers do not send deltas of packages (for good reasons). When you upgrade, you download the whole thing again.

>>59111055
It deletes the old version

Because developers don't give a fuck about optimization as long as the fix works.

>>59111064
>for good reasons
What are those reasons? I am still learning so no bully and thanks everyone for quick replies.

Windows does not have this problem

good 4 u pham

>>59111118
the funny thing is that i only have steam with zero games installed

>>59111118
That is why I dropped Dota 2 in favor of League. Volvo fucked it up with their new HUD and UI trying to look like discount league of legends.

Fuck Steam.

>>59111092
He's right, instead WIndows eats GBs of disk space in shadow copies which must manually be cleared or until 15% disc space is used.

>>59111076
It would just be much more annoying for them to maintain.
Also, new installations would be much longer/more bloated, as they would have to apply possibly hundreds to thousands of deltas when it's installed.

>>59111092
windows updates are way worse it literally takes it over 6 hours to download and install several updates of less than 150 MB

Installing it offline isn't better either windows takes hours to move the file to the update cache

>>59111137
>discount league of legends
kek.
League of legends was a discount heroes of newearth.

>>59111190
and everything was discount warcraft 3

>>59111076
They'd need to keep every previous version so they can generate an appropriate delta for you.

>>59111065
This. The new version is 6.75 MiB bigger.

>>59111177
The monthly rollups consolidate all the past updates after SP1 and take like 10 mins to install. After that you only have .NET Framework and a couple of miscellaneous optional updates.

If you want to go one step further, you can slipstream all the updates into your SP1 ISO.

>game has dlc released

>"dlc" is just a 1mb authentication file

>can't play online without it
>patch offers nothing else outside of the dlc

>>59111205
Not to mention, the user would be forced to keep the tarball after it has already been installed, so they have something to actually apply the delta to.
You're effectively using 2 times the space you need to.

>>59111064
Fedora does it.
I think you can do it with Arch but it's not on by default.

>>59111205
Why can't my PC generate the delta itself. Just compare hashes of each file

>>59111243
what do you mean forced? you can delete cached stuff

>>59111259
Sure, but then you won't be able to use the delta.

>>59111146
Disk cleanup + CCleaner

Next

>>59111250
No, pacman downloads whole packages.

>>59111264
Explain me that. I admit I dont understand it fully , but I thought that when you upgrade you upgrade and the cached stuff doesnt matter anymore so you can delete it.

>>59111076
One is that you can skip some updates and download the latest version there is. If you use deltas you will have to incrementally update. And it is usually safer doing one thing instead of many.

>>59111298
I didn't knew that. Has anyone tried if this works fine?

>>59111195
all these games was created because warcraft was limiting.
You had to install a bunch of separate applications, to keep track of banlists, refreshers etc.
Warcraft was a lot better though. It had a lot of games styles available.

>>59111255
how do you go from comparing hashes to the delta?

Debian has delta packages
http://debdelta.debian.net/

>>59111318
A delta is just the difference between one file and another.
To use a delta, you apply it to the old file.
Say we have mypkg-1.0.0.tar.xz.
It then gets upgraded to 1.0.1, so you download mypkg-1.0.1.tar.xz.xdelta.
So, to get the new file, you "combine" the two files together.
mypkg-1.0.0.tar.xz + mypkg-1.0.1.tar.xz.xdelta => mypkg-1.0.1.tar.xz

If you don't have mypkg-1.0.0.tar.xz, you can't do this, and will have to download it again.

>>59111360
You figure out which files are different and then only download those

>>59111378
Thank you anon.

Because you're not using fedora and don't get deltaRPMs

>>59111175
Storage space is cheap now, why not maintain both. If someone skips a version he just downloads every thing but usually the diff would be used. The mirrors would have less load and be faster.

The extra workload is on the maintainers, who package the uncompressed files, but they would profit the most because their upload time is significantly reduced.

>>59111380
oh, i thought deltas were differences in data within files

>>59111415
maybe what I'm talking about is not a delta.
but it should surely be possible and lead to smaller download sizes?

>>59111428
google does that for the play store
