Hi!

Ximian has now released Evolution 1.0, just wanted to inform you that
it's now available in the Portage tree in net-mail/evolution.

Regards and hope you'll enjoy,

la classe !

portage question number N:
will it break anything emerging to independants packages (ebuilds) in
the same time ?

i dont wanna try it ... as twice in the past doing a CTRL-C on emerge
blowup the whole portage system ....

No, this is a very nice feature in Portage. Since it doesn't use a
single shared database file it's no problem. You should look though that
two seperate emergies doesn't try to install the packages (which might
cause problems since the second might clean the build directory while
the first one is working in there).

[gentoo-dev] Multiple emerges at the same time. ("multi-tasking" in portage)

[Miguel S. Filipe]

While reading this,  It reminded me of a thought i allready had.

Why isn't portage more multi-task? What stops it from, while it's busy 
building something, downloading the packages that its going to 
(build/compile/install) next?
 This would speed up the merging process for those with slow internet 
connections, and it would not affect performance I believe. Is there any 
problem with this? Is it just dificult to implement, or its much more 
tricky and  problematic that it seems?

But.. in that case, I simply can't do.. since the second can mess up the 
first emerge. Right?

However, paralel emerges would be very nice, In fact.. another thing 
that crossed my mind.. is why doesn't portage,  builds independent 
packages in parallel(at the same time)?
  I'm saying this, because i've noticed in my SMP box, that, even when 
i'm "ebuilding" something, i still have a lot  of CPU idle.. (i used top 
to "check this out") it simply appears that, gcc, make and other apps 
don't take full use of the available CPU.

So, launching multiple ebuilds, and downloading, would use the system 
mutch more efficently, (and obviously, higher loads will make it more 
unsresponsive). There must be a way to take advange of this, without 
having the whole system at his knees (limiting the number of parallel 
ebuilds that would be launched automaticaly, but letting the user run 
has mutch has he pretends to).


Is this really a good idea? If not.. why?

This has been discussed, also the possibility to download all packages
before starting to build (so that you can disconnect before starting to
build).

Even on a fast connection it would be very nice to have the downloading
being done while compiling.

I have actually started working on this and should have it done in a
few days.

Re: [gentoo-dev] multitasked emerge (download while build ...)

[djamil essaissi]

I think the minimum we can do right now is:
having the ebuilds work in a totally independant way , for example using
a directory exclusivly.
and/or why not "not" deleting the source tree, so other pakages can use
the already compiled object files ...
this is totally "doable" as the strong point of emerge is the fact that
it doesnt use the shared database stuff ...

thank you guys again for this giant work .

I doubt I have to mention this, but for the sake of "being careful" to make
sure the programs downloaded are finished before attempting to compile them.
:)  Would it be useful to be able to toggle parallel downloading/compiling?
Only case I can see it helpful would be with a fairly antiquated machine.

Don't worry; I'll be covering all the bases.  You will be able to tune the
amount of parallelization you want.  The main feature that everyone will
probably want to enable is to be able to download the sources for an
application that hasn't yet started to compile, since another one is building
at the moment.
