[PATCH 0/6] Add borg

[PATCH 0/6] Add borg

[Leo Famulari]

These patches add the borg backup program [0], which is a more actively
developed fork of attic [1].

Borg is compatible with the current version of python-llfuse (1.0), but
this required changes in borg [2]. Since attic has not had any updates
since borg was forked, I think it's reasonable to guess that attic still
requires python-llfuse@0.41. So, this patch set updates llfuse while
keeping the old version around.

These patches also update python-msgpack and clean up its python-2
variant.

All our package variables use '-' to separate name and version.  I think
this is good choice and we shouldn't use '@' in variable names.

You use a variable ‘python-llfuse@0.41’ (which should be
‘python-llfuse-0.41’ IMO) that does not exist yet, as it will be
introduced in the next patch.  I think you should swap patches 3 and 4.

Would it be better to make a single 'set-env' phase instead?  Or better
yet, are these '..._PREFIX' variables used for make command?  If so,
they should be specified in #:make-flags argument.

Since 'install-file' does not specify a returned value, and we are not
really interested in the returned value, I think it is better to use
'when' instead of 'and' here:

               (when (zero? (system* "make" "-C" "docs" "man"))
                 (install-file "docs/_build/man/borg.1" man))

Okay, I replaced all use of '@' with '-'.

Is the '@' syntax is only meant to be used on the command line?

This syntax has appeared to solve some limitations in the command line
interface which was failing to properly match package names containing
numbers.

I think it is OK to use it elsewhere as long as it does not break
things.  However in the case of scheme variables, I think it is not a
good idea to use '@' because it could lead people into thinking that
there is a strong relation between typing ‘guix build foo@14’ and
defining a variable named ‘foo@14’.

Furthermore ‘@’ (at sign) has a special meaning in Guile (info "(guile)
Using Guile Modules"), so even though it’s currently valid within an
identifier, I’d suggest avoiding it.

I didn't test the change before replying ;)

There is no #:make-flags for the python-build-system, so I have used a
single set-env phase instead.

I asked upstream about some warnings during the docs generation, and
they pointed out that I needed to add a command line. I've attached a
revised patch.

Can I get some feedback on it?

If you keep #t inside 'let', then align it to (setenv ...), or move it
away from 'let':

           (lambda* (#:key inputs #:allow-other-keys)
             (let ((openssl (assoc-ref inputs "openssl"))
                   (lz4     (assoc-ref inputs "lz4")))
               (setenv "BORG_OPENSSL_PREFIX" openssl)
               (setenv "BORG_LZ4_PREFIX" lz4)
               (setenv "PYTHON_EGG_CACHE" "/tmp"))
             #t)

Note the difference: another ')' after the last (setenv ...).

> +         (add-after 'install 'docs

Perhaps it is better to call this phase 'install-doc'.  It's a usual
name that can be met in other recipes.  There is also
'install-man-pages' phase name, but I prefer 'install-doc'.

The rest looks good to me, so if you checked that this program works, I
think you can push this patchset.

Sure, I'll take your advice!

I've been using this program for a few months without problems (yes, I
do restore from time to time).

It's being developed very rapidly for something so critical as a backup
program, so I think that it's still a bit experimental. I could allude
to that in the description. What do you think?

I don't know :-)  Do what seems appropriate to you, I think it will be
OK in any case.

I've been using attic for about 2 months. I checked the github and it
looks like they've recently hit their 1.0.0 release, and they've
commited to keeping API-compatability to at least 2.0. If their software
is as widely used and developed upon as they say it is, their own
developer-users won't likely break their own backup chain
easily/lightly.
