Hello all,

Is it possible to have portage doing compile stuff and download stuff at
the same time? For exemple, merging something that require
dependencies to be merged first.

For example: emerge software-xyz will first compile software-a,
software-b and software-c. Here's the timeline:

1. donwload software-a
2. compile software-a
3. donwload software-b
4. compile software-b
5. donwload software-c
5. compile software-c
7. download software-xyz
8. compile software-xyz (goal!)

My question is: is there an option or can developers add a feature to
have this kind of timeline (parallel tasking)?

Download process Compile process
1. download software-a
2. download software-b 1. compile sofware-a
3. download software-c 2. compile sofware-b
4. download software-xzy 3. compile sofware-c
4. compile sofware-xyz



Regards

Not yet, portage-ng might have this when it's done but for now the
answer is no. You could of course just do "emerge -f <package>" wait few
packeges to finish, and then do "emerge <package> on another
console/xterm. Just remember to give "-f" version of emerge enough time
so that the second emerge process won't start fetching same file.

More sophisticated option is to check out the scripts some people have
posted in gentoo forum.

a quick hack is like Tuuka said:
emerge -f <package> &
<wait a little bit>
emerge <package>
-mike

That is what I do as well, still, I would't recommend it to someone
who doesn't have a decent idea of how fast certain packages will
compile and how long the source takes to download with your internet
connection. You do not want the building thread to catch the
downloading thread.

I believe that this was proposed to be a feature of portage-ng.

That's true. A more secure option in that sense would be to use some
script for the purpose. With some effort I found this:
http://forums.gentoo.org/viewtopic.php?p=219446
script from Gentoo forum. It hasn't been updated for a while and has at
least one problem (or more like a feature) that's mentioned on the page.

I remember something like that too.
