[gentoo-user] GCC upgrade from 4.5.3 to 4.5.4 automatically removes 4.5.3???? Wtf???

[Tanstaafl]

This has never happened to me before...

Since when did a simple GCC upgrade *automatically* REMOVE my prior GCC 
install???

I have *always* kept my prior GCC around for a while, if not until the 
next upgrade, just as something to fall back on if the current one breaks.

I am NOT a happy camper.

Since always if both versions are in the same slot, which is what I would
expect for a "simple upgrade". A major version step would be in a
different slot (4.5, 4.6 etc) and would be installed alongside your old
version (until you depclean).

It has always been that way for packages in the same slot.  4.5.3 and 
4.5.4 are both in the "4.5" slot.  I think you're confusing 
patch-version upgrades with major and minor-version ones.  If you emerge 
GCC 4.6.3, your 4.5.4 version will be kept.

If you really wont to keep multiple patch-versions, then you must set 
the "multislot" USE flag for GCC.  But unless you have a reason to do 
that, and it seems you don't, there's no reason to have multiple such 
versions installed.

This always happens if the gcc your are upgrading to is in the same
slot as the previous one. It is like a normal package upgrade. You
can't keep both gccs in the same slot. gcc preserves installations
only if they are on different slots. And please write proper subject
on emails. "WTF" is not really appropriate for a mailing list.

Well, I've been managing this gentoo server since I installed it over 8 
years ago, and I don't *ever* recall a GCC upgrade removing my prior 
version.

Don't be stupid. I see that all the time... if you don't like it just 
ignore it.

FWIW, My boxes for the last two years have always removed patch
versions. Depcleans remove old minor versions, if nothing depends on
them.

All of us told you that you are wrong. Since you insist that Gentoo
always keep multiple gcc versions of the same slot around, then ok , I
guess you know better.

I'm simply saying that I have always been very careful with GCC upgrades 
(among a few others), and I have always kept the prior version around, 
using gcc-select to switch to the new version after the upgrade.

I guess the only explanation if what you guys are saying is correct is 
that I've never done a minor upgrade for the version in the current slot...

Weird...

Basically any slotted package works this way. Upgrades within the same
slot replace the previous version within the same slot.  You can only
have one version installed in each slot at any given time.

Using eix we can see the versions currently in portage (as of my last
sync) for each slot:

[I] sys-devel/gcc
     Available versions:
        (2.95)  *2.95.3-r9 ~*2.95.3-r10^s
        (3.1)   *3.1.1-r2
        (3.2)   **3.2.2^s *3.2.3-r4
        (3.3)   (~)3.3.6-r1^s
        (3.4)   3.4.6-r2^s
        (4.0)   ~*4.0.4^s
        (4.1)   4.1.2^s
        (4.2)   (~)4.2.4-r1^s
        (4.3)   (~)4.3.3-r2^s{tbz2} 4.3.4^s{tbz2} (~)4.3.5^s 4.3.6-r1^s
        (4.4)   (~)4.4.2^s{tbz2} (~)4.4.3-r3^s 4.4.4-r2^s{tbz2}
4.4.5^s{tbz2} 4.4.6-r1^s 4.4.7^s
        (4.5)   (~)4.5.1-r1^s{tbz2} (~)4.5.2^s{tbz2} 4.5.3-r2^s{tbz2} 4.5.4^s
        (4.6)   (~)4.6.0^s (~)4.6.1-r1^s (~)4.6.2^s (~)4.6.3^s{tbz2}
        (4.7)   [M]**4.7.0^s [M]**4.7.1^s

So, for example, you can see the 4.5 slot contains 4.5.1, 4.5.2,
4.5.3, 4.5.4. You can only have one of those installed at any given
time.

Off the top of my head, the only packages that routinely have slots
for every patch release are kernel packages.

Sorry... I should have said 'That is stupid'... I didn't mean that *you* 
were stupid, I meant that what you said was stupid, and it was... I see 
people use wtf on lists all the time, so saying I shouldn't use it is -

Every mailing list is like its own group of friends and acquaintances,
and has its own social rules. Just because some lists uses phrases
like WTF doesn't mean it fits into the cultures of the rest.

Not that _I_ care, but obviously others do, and so I filter myself accordingly.

Well, then this simple little command should help you refresh your
memory. It shows every install and uninstall of gcc on your system.

With 8 years of emerge.log you are good to go

genlop -ul | grep 'sys-devel/gcc-[0-9]'

And this week's prize for unnecessary use of pipes and grep goes to...

Nope, we not only need the time when gcc was unmerged (-u), but also
when it was merged (-l). When there's little time difference between
merge and unmerge we can assume, that portage auto-cleaned the old
version of gcc. If you combine -u and -l you need to grep (to be exact
sys-devel/gcc-[0-9], because of sys-devel/gcc-config and
sys-devel/gcc-apple).

Yeehaw cowboy :) :)

genlop, unlike qlop, does exact matching by default, so gcc mtches only
gcc, not gcc-config (use -s if you want that). When you give a package
name all merges are shown by default (-l is to show the full
history), so the command I gave does what you want, like this

     Thu Jun 21 01:45:05 2012 <<< sys-devel/gcc-4.5.3-r2
     Thu Jun 21 01:45:33 2012 >>> sys-devel/gcc-4.5.3-r2
     Mon Jul 16 10:30:01 2012 <<< sys-devel/gcc-4.5.3-r2
     Mon Jul 16 10:30:32 2012 >>> sys-devel/gcc-4.5.4
     Thu Sep  6 11:24:27 2012 <<< sys-devel/gcc-4.6.3
     Thu Sep  6 11:24:45 2012 >>> sys-devel/gcc-4.6.3

     Thu Sep  6 11:26:43 2012 >>> sys-devel/gcc-4.5.4

Except it is coloured by default when outputting to a terminal, merges in
green, unmerges in red. Using -l and then grep is saying "show me
everything, oh no, cut out anything that's not gcc" rather than "show me
all gcc merges and unmerges".

I tried your command before answering you - so I don't look like a fool :)
And I am 100% certain that genlop -u <package> only showed unmerges when I
tested it on my workstation (that's the reason I added -l | grep). However,
just now I tested it again on my notebook, and it works like you described
it (and like how you would expect it to work). Have to try it again on my
WS on monday.

Anyhoo, my point was to show the OP how he could check for himself that
portage always unmerges older packages when upgrading to newer versions in
the same slot - and for that, both solutions work.

Going to bed now

If you want gcc's minor versions in their own slots, then you want the
mutislot use flag:

:; euses multislot
sys-devel/gcc:multislot - Allow for SLOTs to include minor version (3.3.4 instead of just 3.3)
