[SOLVED] python targets

[Vieri]

Hi,

I'm installing a new Gentoo system, and I'm not used to so many python versions available and each package wanting one or another...

Some want python_single_target_python3_12 other want python_single_target_python3_11, etc.

Should I set PYTHON_SINGLE_TARGET and PYTHON_TARGET globally in make.conf, or should I set python_single_target_python3_12 -python_single_target_python3_11 for each package in /etc/portage/package.use?

I'm trying to install suricata and samba (for instance), but portage keeps complaining about python.

The following USE changes are necessary to proceed:

Use --autounmask-write to write changes to config files (honoring
CONFIG_PROTECT). Carefully examine the list of proposed changes,
paying special attention to mask or keyword changes that may expose
experimental or unstable packages.

I don't want to autounmask-write on this new system if I can avoid it.

What are my options?

[grknight]

net-fs/samba should not need such changes. If you comment out samba related items, besides keeping ads and client, what is the message then?

[freke]

Unless you really want and know why you want some specific python-version I'd remove any PYTHON_SINGLE_TARGET and PYTHON_TARGET from package.use and make.conf and let your profile handle it (iirc it'd be PYTHON_SINGLE_TARGET="python3_13" PYTHON_TARGETS="python3_13" on a 23.0 profile) - then emerge -uvaDN @world or similar and then try and emerge samba again.

[sam_]

suricata was stuck on old Python (bug 952576). I've fixed that but it really needs a maintainer.

[Vieri]

Thanks for fixing Suricata...

So I did emerge --sync and tried again.
Now I didn't have to set the python targets, and I could emerge packages as expected.

Just for the record, here's how I set it up on a fresh Gentoo installation (any suggestions/observations are very welcome):

So, when I emerge samba (let's ignore suricata for now) I get:

Use --autounmask-write to write changes to config files (honoring
CONFIG_PROTECT). Carefully examine the list of proposed changes,
paying special attention to mask or keyword changes that may expose
experimental or unstable packages.

So I added "net-dns/bind gssapi" and I could emerge samba just fine.

Just one last thing so I can fully understand how binary pckage installation works.
The binary package for Samba isn't pulled in and I need to compile it because of which USE flag?
Let's just take sys-libs/tdb as an example since it has less flags. what does the following mean?

Code: Select all

    =sys-libs/tdb-1.4.13 -python python_single_target_python3_12 -python_single_target_python3_13
    =sys-libs/tdb-1.4.13 -python

Does it mean that it was compiled on the official Gentoo BINHOST without the python USE flag and since I set "python" in my global USE in make.conf then it will need to be compiled instead?

Yes. It has matches for your current python targets as well with the second option, but python itself was off.

Setting python USE globally was removed years ago with the recommendation of enable it when you need it for optional functionality on a specific package.

[Vieri]

Thanks for letting me know that setting "python" globally is not needed anymore.
I removed it, and set it only for specific packages (eg. samba for ads).

When updating world I've come up with the following:

Code: Select all

#  emerge -avuDN @world

See this. Do emerge --sync again.

[Vieri]

Thank you very much! I'll sync again...

However, I'm puzzled why portage keeps reinstalling packages that have already been installed correctly (no changes in make.conf).

For instance, I already emerged samba (my USE flags differ from the ones in Gentoo BINHOST so Samba was built from source).
However, emerging it again (or if I emerge @world) reinstalls the package.

Code: Select all

# emerge -pv samba

So why is Portage trying to reinstall the same package (same version, same flags)?

I hope I didn't screw up my system configuration when I first set up python targets...
I removed any reference to python and since then here's my make.conf:

[EDIT]
Do I need to add --selective to EMERGE_DEFAULT_OPTS in make.conf?

[grknight]

However, emerging it again reinstalls the package.

Code: Select all

# emerge -pv samba

So why is Portage trying to reinstall the same package (same version, same flags)?

Because you asked it to.

(or if I emerge @world)

This is different and portage will usually explain why in its output.

[EDIT]
Do I need to add --selective to EMERGE_DEFAULT_OPTS in make.conf?

No, that's a bad idea.

Edit: Please show the full @world emerge command with any issues. It should be like this: emerge -avuDU @world

[Vieri]

Thanks.

I really don't know what happened, but I can't reproduce the problem anymore. A bit embarrassing...

BTW I used -N instead of -U:

Code: Select all

#  emerge -pavuDN @world

Sorry if I reopen this, but while emerge world does not reinstall anything, an explicit emerge package does.

Eg. I already have apache installed. I want to be able to run "emerge www-servers/apache" without any extra options and have portage do nothing if the same package, same version, same flags already exists.

However, if I issue the emerge apache command with my current defaults Portage reinstalls it:

Code: Select all

# emerge -pv www-servers/apache

I think I should stick with -u because I'm not sure -n will update the package if a new version is available or if the flags have changed.

If you do an emerge -v (package) - you're telling emerge to (re)install that package.
You can add -u to tell portage to only emerge the package if the're is an upgrade (if the package is not previously installed it will be installed), similarily you can add -U/-N to onle emerge it if if there's changed/new user-flags

I wouldn't add neither -u nor -n to default-opts, then I'd have to remeber why portage behaves non-default ie. if I wanted to do a re-install of a package (ie. if I have changed gcc-version, env-stuff or something elese) and portage tells me there's nothing to emerge because an -u has been added in the config somewhere...

[Vieri]

Got it. Thanks
