A few questions about packages

A few questions about packages

[-- Attachment #1: Type: text/plain, Size: 617 bytes --]

Hello. Can I remove old package versions and other builds? On the example
of Icecat:

    252.1 MiB [          ]
/5ym67s5vp1vmnc3y4ds4r3687vc3nl25-icecat-52.6.0-gnu1
    252.0 MiB [          ]
/360i9ca4gnm3rsjj8v43ih0j3mfrp40n-icecat-52.6.0-gnu1
    246.8 MiB [          ]
/kd0nnq3i0qarx4vqxcampxfj3igxn84h-icecat-52.3.0-gnu1

(Or is it possible to remove a specific package, in "package-version"
format?)

And the next question, is also about Icecat: version 52.6.0 was compiled
from source. This is too long. Can I create binary package from this local
installation?

If possible, please give a couple of examples.

You can remove all unused packages with “guix gc”.  Individual store
items can be removed with “guix gc -d /gnu/store/…”.

“Unused” means that no profile generation refers to the item, so you may
want to delete old profile generations with “guix package -d” first.

After building it once from source you won’t have to build it again
until the dependencies to Icecat are modified.

Building Icecat does indeed take a long time.  The current version is
52.6.0-gnu1 and should be built by our build farms.  When you’re using
the latest version of Guix then you should be able to get a binary as
soon as the build farms have compiled that package.   Only if no binary
is available you will have to build it from source.

"guix gc" will delete all packages that are no longer required. Most 
probably that includes all Icecat installs except for the latest. 
However, if two users on the system have different versions of Icecat 
installed, both will be kept.

In a sense you already have one, stored on your computer. So I guess 
your question is how you can use this binary package on a different 
machine, right? There are two answers to this question:

  1) If the other machine also runs Guix, the answer is "guix archive":
 
https://www.gnu.org/software/guix/manual/guix.html#Invoking-guix-archive

  2) If the other machine does not use Guix, have look at "guix pack":
     https://www.gnu.org/software/guix/manual/guix.html#Invoking-guix-pack

Thanks to all respondents, I thumbed through manual. All my questions
relate exclusively to 'reconfigure' and old grub menu entries, and old
system configurations.
guix gc Ok, next:

guix gc -d /gnu/store/kd0nnq3i0qarx4vqxcampxfj3igxn84h-icecat-52.3.0-gnu1
finding garbage collector roots...
guix gc: error: build failed: cannot delete path
`/gnu/store/kd0nnq3i0qarx4vqxcampxfj3igxn84h-icecat-52.3.0-gnu1' since it
is still alive

 - icecat-52.3.0-gnu1 was installed in the first (or second) system
configuration, next 'reconfigure' and 'reconfigure' and 'reconfigure'.. Or
two version of linux-libre - too there is too much :)

Without emacs-guix you need to do this manually by deleting the links for
the old system generations under /var/guix/profiles/system-*-link.

Just don’t delete the latest system generation.

Re: A few questions about packages

Another question.. Package zip refers to "compression" package source.
Can I not specify individual packages, but install all of this group?
Can I do this with a single command? (This is a general question, not
just about zip).

There’s no direct way to do that, but you could always do:

  guix package -i $(guix package -A | grep 'compression\.scm' | cut -f1)

Your user’s profiles are not the only ones that can keep packages alive.
You also have a system profile with potentially multiple generations.
They are stored under /var/guix/profiles/system*

> (guix gc --optimize not do anything)

As the manual says, this is for deduplicating files in the store.

This we already figured out previously in this thread :) 
And:

"Label             : GNU with Linux-Libre 4.15.7 (beta)
Prev. generation  : 0  
Current           : Yes
Number of packages: 88  Packages
File name: 
  /var/guix/profiles/system-4-link"

The question remains.

I also have a lot of those in my store, although I rarely do a guix gc.

Suppose you don't change anything on a packages definition, i.e.
leave name, version, depencencies, build-system etc. completely as they
were. If you then change anything on the dependencies of that package
(or its sub-dependencies) it will get rebuild (or re-downloaded) with
the same package-name and package-version but under a different
hash-sum.

That's the reason why there is the branch of "core-updates" packages
(see point 7 in [1]): Basicly every package in the distribution depends
on a core-updates package. If you change one of the core-updates, the
whole distribution needs to be rebuilt. Because this would cause much
compilation-work on users computers, core-updates will be collected and
compiled by Hydra on a separate branch. If everything is compiled and
under a certain level of errors, it will be merged back into master and
will be available via guix pull.

In your case it could be that you have installed the different library
instances via different guix pulls.

All profile generations are immutable and stateless.  They won’t change
when you install a new library.

Store items are kept indefinitely. You can use guix gc to remove them.
But this of cause works only if they have zero references pointing to
them, i.e. there is no other dependency from the store or a profile
generation linking to it.

I'm not sure if I understood you fully, I hope my answer is the right
one to your question. Since a week or so we decided to invite people
also to write in their language and not only in English. If that helps
you, under "Mailing List" you will find the list of languages that are
understood by Guix developers (to be growing):

It is possible to draw a conclusion, that each application refers the

Yes, for each language listed, there is one person within the

Re: A few questions about packages

[Jone]

Thanks, Ricardo.

Then still questions:
the difference in a hash is already enough to read two identical
libraries as two different versions? Whether are available dependences
of one package for another?

Need wiki, not only Manual! :)

Re: A few questions about packages

[Adonay Felipe Nogueira]

> Need wiki, not only Manual! :)

Awesome idea! Although I have been experiencing some bad moments with
wikis nowadays, specially since I don't have stable connection to the
Internet, that said, I must note that: manual is like a wiki, with added
benefit that:

a) manual is readable offline, while wiki needs internet;

b) wiki pages might *not* correspond to the version of your local copy
   of the software;

c) both wiki and manual allow contributions, but manual doesn't dictate
   that one has to do so through a web browser, you can even do so by
   sharing files through thumb drives, emails, forum posts,
   NNTP/netnews, whatever;

d) you don't have to have an account in any website to suggest
   contributions to current manual, you can send it to any member of
   project in any means of communication and transfer that the member has
   available.

In any case, both manuals and wikis allow contributions. If there is
something that needs change, then perhaps someone needs to send a patch
to improve the manual.

I hope this helps clarify things. :D

Languages there is, but there is whether people..
