[gentoo-user] Update portage cache ... horribly slow

[gentoo-user] Update portage cache ... horribly slow

[Paweł Madej]

Hello,

I want to know for what reason there is sth like updating portage cache 
after rsync in emerge sync.

It's very very slow and I dont know why. So my question is could I some 
way turn off this cache?

This cache is used to resolve all packages you want to update,install
or remove from your box; if you turn off this cache you would need to
do the same action to every emerge option; I believe that is better to
let it do just when updating portage tree .... :)

Holpe it helps, Allan

Thx for fast answer.

Ok I'll leave it as is, but maybe is there any way too speedup it? It 
runs on my P3 800 / HDD 5400 rpm more that 10 minutes.

Or it is working on every computer so slowly?

That sounds a bit slow, but not massively so, it takes a long time.

You could CRON your emerge sync to happen in the middle of the night,
and then you won't have to watch it. :-)

For something you should only do once a day, 10 minutes isn't that bad
though.

Cheers,

Dunc

I sync not day by day but 2-3 times a week but when I sync I want to run 
just after it emerge of updates (I follow new ebuilds on [1] site and 
run emerge if sth interesting for me  appears there).

My other question is if there is some script which could follow rrs from 
[1] and run emerge sync and emerge -uND world after there is for example 
10 ebuild updated comparing to my system, or other way that it will 
email me that there is 10 ebuilds new and i should run sync manually.

Well, esync might be what you want-- it's part of gentoolkit, and while
it won't do any emerges for you, it will display (or mail you, which is
how I do it) the list of updated packages for the day, with a note as to
whether the package is an upgrade for your system, new to your system,
or the like. Here's an example of the daily mail I get when I run esync
as a cron job and mail myself the output:* Importing old portage tree

 * Doing '/usr/bin/emerge sync' now

 * Doing 'eupdatedb' now


 * esearch-index generated in 4 minute(s) and 23 second(s)
 * indexed 10357 ebuilds
 * size of esearch-index: 1618 kB

The only upgrade (this is from the 27th), is firefox, but I might take a
look at wmail. Nothing else interesting to me on this particular list.

I suppose if you really felt that you wanted to have an emerge of the
new packages done automatically, you could always create a script to run
esync and mail you the output, then run emerge -uD world after esync
completed successfully (doesn't seem much point in using --newuse if
you're not going to be there to look at the output), but I prefer to do
my emerges manually.

Hope this helps,
Holly

I'm not really sure automating your updates like that is a really good idea
especially in light of a few new package layouts that break things. Wouldn't
that just bite, wake up and, oops the system's broken and I have no idea
why.

esync is part or esearch. If you prefer eix, it has an equivalent now,
diff-eix.

This is the script I run from cron.daily

emerge world --update --deep --newuse --pretend --verbose | Mail -s "Updated packages for $(hostname)" neil 
glsa-check 2>/dev/null --test all | Mail -s "GLSA check on $(hostname)" neil

I second esync. It is a nice script that runs a little faster than 'emerge 
sync'. I have a little script in my daily cron list that follows...

#  esearch: do 'emerge esearch'
#

It calls emerge sync, so how can it run faster?

# This script imports the current esearch index,
# calls `emerge sync` and `eupdatedb` and then
# shows the packages which were updated or added
# during the sync.
#...
syncprogram =   "/usr/bin/emerge sync"

Umm... i didn't realize that! :p Until now I hadn't actually looked at the 
esync script.

I guess while I was trying it out, subjectively it seemed to do its thing 
faster. Perhaps that was down to the fact it calls emerge with the verbose 
option off, which provides less overhead in the terminal. But obviously that 
is easy enough to do from the command line as well. Still I get the 
functionality of esearch in the bargain so it suits me.

Be grateful you're not running my PIII 600MHz.  If you also are running
X with a browser, xmms, or mplayer and updatedb decides to join in, then
20 min to 1/2 hour is a possibility!  I'll make a mental note to measure
how long it takes next time I sync.

I've had a lot of luck with the cdb patch for portage.  It's mentioned in
the gentoo wiki.  I haven't measured to see how syncs are impacted but
regular portage stuff seems faster.

This sounds quite interesting, but I can't find any mention of this
patch on the Wiki, even after two searches on the Wiki and 3 on Google.
I feel pretty dumb, since Paweł clearly found it easily, but I can't.

I was looking under How-Tos (and searching in the wiki/google for cdb
patch). Weird that the wiki search engine didn't find it, though. Maybe
I just didn't go through enough of the hits.

Better (I'm on the downslope from peak 'I can't sleep because I can't
breathe laying down, do we have any more Vicks VapoRub?' miserableness),
but clearly not back up to par :) . My bf wants me to go back to bed,
but I'm too hardheaded to listen (since I do feel better, and I can get
some minor maintenance done), sitting here with a pot of tea and a lot
of tissues and not doing anything too stressful (meaning all my projects
are backed up, including one 'official' and public one, dammit).

Thanks for asking :) .

And thanks for the link, everybody.
