[PATCH] Add 12 rubygems.

[PATCH] Add 12 rubygems.

[-- Attachment #1: Type: text/plain, Size: 703 bytes --]

Hi,

These patches are all working towards the popular Ruby web frameworks 
(Rails/Sinatra). I tried where possible to do at least rudimentary 
testing when dependency cycles arose, and fall back to the source code 
on github when the gem on rubygems didn't contain tests.

Actually these are the easier parts to package - the deeper hole is 
ExecJS which requires therubyracer at test time which requires v8 and 
thus a bunch of chromium-related packages. Is anyone thinking about 
working on that?

Unfortunately none of these builds are reproducible because rubygems in 
Guix generally aren't. For one, this is because .gem files are archives 
whose contents are timestamped.

... and thanks!

ben

We should arrange so that gems are created with a fixed timestamp and
UID/GID, and a well-defined file ordering, as with:

  --mtime=@0 --sort=name --owner=root:0 --group=root:0

We also need to make sure gzip is always run with -n/--no-name.  That
way, the gz files above will not include an additional timestamp.

From what I can see in
<git://git.debian.org/git/reproducible/notes.git>, this is not addressed
yet in other distros.

HTH,
Ludo’.

I found the same problem with Java stuff.  “.jar” files are archives of
the generated “.class” files and they contain an automatically generated
manifest.  To fix this in a build system I’m planning to unpack all
files from the “.jar”, then “touch -d @0” each file, and then repack
with “jar” without creating a new manifest.

So far “touch”-ing every class file after compilation and leaving off
the manifest at jar creation time has shown that “jar” archives can be
made reproducible.

“gem” archives are really just slightly modified “tar” archives, aren’t
they?  Maybe we could add a phase to the ruby-build-system — or modify
the “build” phase, which unpacks and rebuilds the “.gem” archive.

Yep, they are just tar files. But since it is just a cache, can we just 
delete the gem file as per attached? Too ham-fisted?

Of the 104 gems in my checkout of gnu/packages/ruby.scm, only 14 are now 
not reproducible (as opposed to 104 beforehand I think). None seem to 
fail to build the traditional way. I believe the remaining offendors are 
not reproducible because they compile native extensions leading to 
further timestamp issues. I think after this we are OK to test pure Ruby 
packages for reproducibility.

The offendors:
ruby-byebug
ruby-eventmachine
ruby-ffi
ruby-json
ruby-libxml
ruby-nokogiri
ruby-nokogumbo
ruby-ox
ruby-pg
ruby-rack
ruby-redcarpet
ruby-redcloth
ruby-rjb
ruby-unf-ext

Another case where Ruby was easier than Java? :P

Thanks,
ben

Good idea!  I don’t know if the existence of the cached gem is checked
for by any Ruby tools (bundler or the like).  Is there some
documentation about this cache?

I’d prefer to keep ‘(zero? ...)’ and only delete the file when the
‘system*’ call above succeeded.  It would be nice if we could propagate
any bad return value from ‘system*’ to the end of the procedure.

Maybe something like this:

  (and (zero? (apply system* ...))
       (begin (delete-file ...) #t))

It’s a bit clunky but the return value would still be #f if ‘system*’
fails.  What do you think?

I wondered that too, but I built all of the ruby packages again without 
issue and many of them use bundler. It also doesn't seem like a good 
idea for bundler to use cached gems since I would guess that gems that 
are downloaded but fail to install are kept in the cache. I also wasn't 
able to see any mention of the cache in the rubygems API.

Subject: [PATCH] build: ruby: Remove cached gem after install.

The .gem file stored in GEM_HOME after install is both redundant and an
archive that stores timestamped files which makes builds non-deterministic. So
delete it after 'gem install'.

* guix/build/ruby-build-system.scm (install): Remove cached gem after install.

Abandoning the deletion approach only makes sense if we have control
over the way “gem” packages up archives.  As far as I remember “gem”
archives are actually regular tarballs with some additional metadata.
The “gem” command itself does not expose any means by which we could
control the mtime of the archive contents.

As the “.gem” file itself is likely redundant I don’t see a problem
removing it as you proposed.

@Dave: what do you think about just removing the cached “.gem”?

It looks good to me, thank you.

So I guess you (Ricardo?) can push it now.

Ben, do you confirm that the ruby-* packages you tested are indeed
bit-reproducible after this change, using --rounds=2 or so?

Thank you!

I do confirm this. Well, I used build then check so that dependencies 
weren't checked, but same thing.

I noticed that ruby-lumberjack, a dependency of ruby-guard, now fails to 
build (and fails before this patch and outside guix). This is because it 
fails to pass tests in early January.. not a source of non-determinism I 
was looking for, but thanks for writing tests into that package - picked 
up the easily fixed bug.
https://github.com/bdurand/lumberjack/pull/26

Thanks for pushing the patch.

Hi Ben,

Do you have an account on Savannah?  If not, I invite you to create one

Sweet, thanks muchly.

My new savannah account name is benwoodcroft

I'll try not to mess things up too badly. Great to be more officially a 
part of GNU, though I'm sure I'll never be able to repay all the

I found one instance where bundler uses cached gems - when installing a 
bundle using --local

        --local
               Do not attempt to connect to rubygems.org. Instead, 
Bundler will use the gems already present in Rubygems´ cache or in 
vendor/cache. Note that if a appropriate platform-specific gem exists  on
               rubygems.org it will not be found.

This doesn't seem like a deal breaker for the deletion approach to me 
though.

“github” or “GitHub”?  I think it should be the latter.

I’m still not happy with breaking lines right after “string-append”, but
I’ll just stop mentioning it :)  It’s not a problem, but it does look weird
to me.

Please use two spaces between sentences.  Also capitalise “disable”.
The comment should better be moved right above ‘(replace 'check ...)’,
so that it stays relevant even when new, unrelated build phases are
added.

I think “This package” would be less confusing than “The ANSI project”.
At first I thought this sentence describes where the ANSI code standard
comes from; but then I realized that the package is also called “ansi”.

Please wrap all module names in “@code{...}”, e.g. “a @code{Mixin}
module”.

I’ll try to comment on the other patches later.

The license is actually just one of “(list license:gpl2 license:gpl3

Also here I’d remove “Adobe’s”.  Additionally, you could wrap “Portable
Document Format” in @dfn{}:

     "This library provides methods to encode and decode Ascii85
binary-to-text encoding.  The main modern use of Ascii85 is in
PostScript and @dfn{Portable Document Format} (PDF) file formats."

I would prefer moving ‘(and’ and ‘(zero?’ on the same line and then
split the “rubytest” line.

Could you please wrap all class names in @code{...}?  E.g.

The indentation here looks wrong.  The paren of “(base32” should be
aligned with the “s” of “sha256”, and the opening quote of the string
should be aligned with the “b” of “base32”.

This line is short enough to merge it with the “(lambda _”.

That’s not very descriptive, but I know it’s difficult to come up with
good descriptions when the upstream descriptions are so vague.  Oh
well.  Let’s leave it like this if you cannot come up with something a
little more expressive.

The first line of the comment looks awfully long.  There is no space
after the first sentence.

Why “--copyright”?  Are you trying to run qed to see if there are any
errors, because there is no test suite?  If so, maybe you could state
your intention in a comment.

Maybe this is better:

     "@dfn{Quality Ensured Demonstrations} (QED) is a test framework for
@dfn{Test Driven Development} (TDD) and @dfn{Behaviour Driven
Development} (BDD) utilizing Literate Programming techniques.  QED sits
somewhere between lower-level testing tools like @code{Test::Unit} and
requirement specifications systems like Cucumber."

But... we are still downloading from Rubygems.

Again, the comment looks a bit long; also add another space after the
first sentence and capitalise “Disable” at the beginning.

Same as above: capitalisation and space after first sentence.

On one line please.

And that’s it as I reviewed the first patch already.  Thanks a lot for
the patches!  Could you please send updated patches?
