[bug#35653] [PATCH] gnu: Add rcm.

[Josh Holland]

Hi,

Below is the first package definition I have written for Guix, defining
the dotfile management suite rcm[0].  I'm sure there are changes to be
made before it can be merged, and I did have a few issues while I was
writing it.  However, it does now build, install and run fine on my
local machine.

First, I wasn't sure whether it fits into an existing module already.
I had a look through the contents of gnu/packages/ but I didn't see
anything that really stuck out.  Perhaps it fits into shellutils?

Second, I had a lot of trouble with the test suite.  The first thing
that I had to solve was some hardcoded paths in the test cases, which
I solved with the following argument to `#:phases`:

(modify-phases %standard-phases
  (add-after 'patch-source-shebangs 'patch-tests
    (lambda _
      (substitute* '("test/rcrc-tilde.t"
                     "test/rcdn-hooks-run-in-order.t"
                     "test/rcup-hooks-run-in-order.t")
        (("/bin/sh") (which "sh")))
      (substitute* "test/rcup-hooks.t"
        (("/usr/bin/env") (which "env")))
      #t)))

This may or may not be the right way to go about things; I'd appreciate
some feedback on that.

However, I was still having issues with certain tests
(`test/rcup-hooks.t`, `test/rcdn-hooks.t` and possibly others)
non-deterministically failing trying to create and read /tmp/test files.
I'm not sure how to fix this, or even what's causing it: every time I
tried to reproduce it by hand the tests passed.  I assume that something
is deleting /tmp/test while the test is running but I'm not sure what.
In the end I just disabled the tests, since even passing XFAIL_TESTS
doesn't work as sometimes the tests just pass.

If there are any ideas to solve the tests, or any other issues that need
fixing, I'm happy to re-submit the patch.

Thanks,
Josh

Yes, and it's not so important in which module what is.  The module
name is not part of the package name anyway, so we are mostly using
it to manage compilation complexity (sigh).  Developers can find it
using "guix edit rcm" anyway.

I try not to introduce a new module for each package because it leads
to a lot of file header duplication, and at some point the comment/code
ratio is getting ridiculous--but, technically, even that would be fine.

Looks fine.

From your description, try (#:parallel-tests? #f) instead of (#:tests? #f).

Nice work!

Some test scripts still have /bin/sh

I'll just leave it in its own module for now then, and if a maintainer
wants to move it either when it's merged or later down the line that's
fine.

> From your description, try (#:parallel-tests? #f) instead of (#:tests? #f).

Oh of course, that makes perfect sense!  That fixes it and all the tests
pass now.

> Some test scripts still have /bin/sh

AFAICT the only one I'm not patching is `test/rcup-standalone.t` and
that's kind of a weird one, because it's testing the feature to output a
standalone shell script rather than run it.  Changing that would require
patching the rcup script itself and I don't think that's worth it,
especially as the script uses the bash default value syntax to allow
all the commands to be overriden.

If I'm still operating git send-email correctly, a new patch should be
attached with these changes, and a better commit message.  I also updated
`gnu/local.mk` because that seems to be a thing I forgot initially.

Thanks,
Josh
