I am preparing a guide on our (youbroketheinternet-overlay) way we work
with git for a long time now, it would be relatively easy to do this with
a domain name and not just tor.
The tor way involves setting up tor, torsocks, creating a dedicated git
user, set up a hidden service on port 9418 (git default), and for the git
repositories which should be exported touch a file "git-daemon-export-ok"
in the bare repository on the machine running this.

I will post this on the Gentoo wiki and probably finish it this month,
it should be easy to apply for any system though.
Adding dynamic dns name with OpenNIC or commercial/free providers to it
should be doable too, as I used it with a domain name for some time too.

Hello Jelle,

I suggest that you avoid the word "ecosystem" when describing the work of
people who have designed and contributed to Guix.

We should adapt pypi-uri to handle the new scheme, but in the meantime,
can you put the hash on its own line, to reduce noise in the commit log
for future updates? This would be the whole thing:

  
"96/e0/430fcdb6b3ef1ae534d231397bee7e9304be14a47a267e82ebcb3323d0b5/"

> +(inputs

Does it use setuptools at run-time or just at build time? If the former,
then it can be a native-input. Also, if it's only required for the
python-2 version, can you use the python2-variant system as shown in the
package definition of python2-pyicu?

`guix lint` prefers to begin the description with a capital 'P'.

Also, it's nice to wrap 'lex' and 'yacc' in Texinfo markup like this:
@code{lex}. Then, the word 'lex' will be rendered specially. I'm not
sure if we have a policy on this but I think it's useful when referring
to other packages.

[GSoC] Integrating npm into the Guix ecosystem

[Jelle Licht]

Greetings Guix hackers,

It has been some time since my last mail to this list, so I wanted to
share what I have been up to. For the people who might want to watch
along after today, I will be posting the changes that should not break
everything immediately to [1]. (Apologies for it being web-only, my
sysadminfu is still lacking. If you know how to easily and most of all
securely expose a git repo for read-only anonymous checkouts, please do
tell).

These first two weeks, I have mostly been keeping busy with writing some
of the features that will quickly allow me to identify problems with the
import and build procedures as I envision them. I was in luck; there
were many of these problems as I found out ;-).

One of the things that kind of worried me for a while was the fact that
npm was broken after my first attempts at writing _anything_. At this
moment, still being somehow intimidated by the guix code base, I had
quite some trouble finding out what was happening; it turns out
somewhere along the way, the way Node was built since version 6 (using
guix, at least) has changed, making the `npm' in the PATH of your guix
profile a _copy_ instead of a symlink to the actual executable
`npm-cli.js' script.

A patch to fix this is currently still brewing, so expect to see it
soon. In order to continue a bit (and implement something that actually
works), up till now I have worked with the 5.10 release of node.

After toiling a bit to find a nice way of getting node to find
dependencies, I started out with the NODE_PATH variable. Although some
alarming messages I read some time ago indicated this method of allowing
node to load modules is discouraged, but not deprecated.

At first I wanted to make use of a variant of the npm command to
actually take care of installing node modules to the store outputs; some
of the advantages include:

- The 'correct' files are ignored/always included
- The 'correct' symlinks are generated to executable scripts, man-pages
  and other documentation.
- Automatically up to date with new conventions in npm-land

While that all seemed (and still seems) quite nice, it happens to be the
case that npm is quite particular about dependencies that it will
accept. Patching the actual dependencies and versions in the
`package.json' file was another option, but after some consideration and
advice from my mentors I decided this would not work nicely in the long
term. Instead, I want to implement the relevant set of behaviors in
guix, of course allowing for our particular kind of dependency
management.

As such, the current installation phase mostly involves copying files to
their expected locations. I added support (as an exercise in build
system arguments) for 'global' installs[3], which as far as my current
bare-bones implementation is concerned means properly symlinking
executable scripts. In the (near-)future, I am looking into properly
wrapping these scripts to make sure the amount of propagated inputs is
kept to a minimum. As a sanity test, I packaged [4] in my own little
scratchpad. If you want to follow along, it only takes 4 `guix import
npm' invocations ;).

The current importer functions as expected for the "90%" of packages
that I tried. A problem that I ran into that I could not recognize as
easily in other importers is the fact that the npm community only
distributes the artifacts that you need to run the npm modules, but not
to build them. In most trivial cases, there are literally no
differences, but especially for more complicated packages involving
transpilation steps, this poses a problem.

As such, the importer can not actually 'know' of the location of the
source. Right now it uses some limited heuristics to probe GitHub
repositories for a tarball release, and if these are not found or the
sources are hosted at non-GH sites, it tries to check out a tag
according to the npm packaging conventions (SemVer).

The most important thing that needs to happen right now would be to
extend the range of packages that are buildable by the build system. A
combination of working towards having working 'large' packages and test
frameworks should help me quickly identify problems. This will be my
main focus for the next week.

I am aware that the current importer is quite brittle, so this needs to
change as well. As I run into problems (or someone brings them to my
attention), I will improve the quality of this subsystem as well.

If you have some advice, questions or problems, please do not hesitate
to reply. The same goes if you have some npm packages you would love to
see packaged.

Thanks a bunch for reading this WoT :)

I noticed that the output does not refer to zlib:

$ guix gc --references $(./pre-inst-env guix build msgpack)
/gnu/store/8m00x5x8ykmar27s9248cmhnkdb2n54a-glibc-2.22

/gnu/store/v39bh3ln3ncnzhyw0kd12d46kww9747v-gcc-4.9.3-lib

However, the compilation fails without it.

We need to make sure that msgpack can find zlib at run time. Lukas, can
you check if there is a build-time configuration option to provide the
path to zlib?

I roll back from the GRUB menu if I've totally broken the system.
Otherwise, I use Git to manage the system configuration and roll back by
checkout out an earlier commit.

But, I think we should be able to switch to arbitrary system generations
and delete generations with the Guix tools.

Hello,

I think match-lambda is not documented in the guile manual (it only

Either these files exist or they do not.  Better to just have three

Is this a nice way to disable tests?  I dunno.  Why not change the test
name from TestFoo to DisabledTestFoo ?  Then it would not get run.

Also let's avoid car and cdr, and instead use match-lambda:

  (match-lambda
   ((file . pattern)
...))

But let's also avoid dotted pairs in bigger literal data structures;
it's ugly when there's lots of punctuation around.  So if you change the
lines to be like

  ("net/net_test.go" ".+TestShutdownUnix.+")

you can

  (match-lambda
   ((file pattern)
...))

Note the lack of " . ".

> +(list
> + '("net/net_test.go" . ".+TestShutdownUnix.+")

Here make the whole list a literal instead of calling `list' on a list
of quoted datums:

  '(("net/net_test.go" ".+TestHostname.+")
...)

It would definitely be a welcome addition!  The refactoring that was

Indeed.  Service upgrade is conservative, so it will not stop running
services, because it cannot know if this is something the user wants and
if it is safe; only services that are not currently running are loaded
and started upon reconfigure.

  http://bugs.gnu.org/22039

To improve on this, I think it should be possible for Shepherd services
to provide an ‘upgrade’ method in addition to start/stop, for those
services that can be upgraded with no downtime (there aren’t so many of
them, though.)

‘guix system reconfigure’ could explicitly update /run/current-system to
point to the old system.

Not much, indeed.

The problem with system rollback, as you’ve seen, is that we lack
information about the old system, such as what its activation script is
and what its Shepherd services are.

We could add the activation script’s file name to the ‘parameters’ file
that you see in the result of ‘guix system build foo.scm’.  But it would
be hard to add a forward-compatible yet complete description of the
Shepherd services there.

ISTR that GRUB has a mechanism to record the last selected menu entry
and to use that as the next default entry.

Now, it’s not always what one would want to do.

However, ‘guix system roll-back/switch-generation’ could generate a
grub.cfg where the default menu entry points to whatever old generation
has been selected.
