Subject: [PATCH] Add ripgrep and many rust dependencies
Date: Mon, 16 Dec 2019 19:08:45 +0000
[Message part 1 (text/plain, inline)]
Hi Guix,

I have missed using the rust tools I use outside of Guix. Ripgrep was the
first one I could build thanks to the work on the rust build system.

Of course, it required adding over 200 dependencies.

Some of these have cyclic dependencies, as you all know. What I understand
is that the rust community is OK with including cyclic dependencies as test
dependencies.  I am actually seeing how useful that is. Consider the system
tests in the guix repository. Certainly that would require including guix
as a dependency to guix.

I also left the cargo inputs and dev inputs commented out just in case
someone wants to put them back in the future and to give a sense of the
topological order of the patches.

Having imported ripgrep some months ago, some of these dependencies will
require updates, but I did not want to break the working version of ripgrep
at the end of the line.  Otherwise I have fixed the other lint errors and I
have been using ripgrep for several months.

- John

Hi all,

I submitted my patches this morning in #38640.  Thanks for the continued work on the rust build system.  I like rust tools quite a lot.

I feel your pain, I'm doing the same with julia packages, where every
week at least 10 of them are updated making diffucult to create a patch
that is up to the day.

I just tried your set of patches and I can confirm that ripgrep is
working (and is fast! I really missed it)! Long live to ripgrep!

Looking at them quickly, I noticed the following have the "a" in add lowercase:

- [PATCH 160/206] gnu: add rust-flamer-0.3.
- [PATCH 073/206] gnu: add rust-tokio-sync-0.1.

Also:
- rust-miniz-oxide-c-api-0.2: defined but not used
  - contains an undefined reference to rust-libc-0.2.58
- rust-futures-channel-preview-0.3: home moved to
  https://rust-lang.github.io/futures-rs/
- rust-demo-hack <at> 0.0.5: all the source URIs are unreachable
- descriptions not ending in dot:
  - rust-stdweb-internal-macros-0.2
  - rust-base64-0.10
  - rust-bit-set-0.5
  - rust-blobby-0.1
  - rust-block-buffer-0.7
  - rust-byte-tools-0.3
  - rust-c2-chacha-0.2
  - rust-cast-0.2
  - rust-cexpr-0.3
  - rust-chrono-0.4
  - rust-console-0.7
  - rust-crc32fast-1.2
  - rust-criterion-0.2
  - rust-crossbeam-0.7
  - rust-crossbeam-channel-0.3
  - rust-crossbeam-deque-0.7
  - rust-crossbeam-queue-0.1
  - rust-crossbeam-utils-0.6
  - rust-cpp-demangle-0.2
  - rust-demo-hack-impl-0.0
  - rust-digest-0.8
  - rust-discard-1.0
  - rust-encoding-0.2
  - rust-encoding-index-*
  - rust-encoding-rs-0.8
  - rust-encoding-rs-io-0.1
  - rust-erased-serde-0.3
  - rust-failure-derive-0.1
  - rust-fake-simd-0.1
  - rust-flame-0.2
  - rust-foreign-types-macros-0.1
  - rust-foreign-types-shared-0.1
  - rust-fuchsia-cprng-0.1
  - rust-generic-array-0.13
  - rust-heapsize-plugin-0.1
  - rust-hex-literal-impl-0.2
  - rust-insta-0.8
  - rust-jemallocator-0.3
  - rust-miniz-oxide-c-api-0.2
  - rust-mio-0.6
  - rust-linked-hash-map-0.5
  - rust-num-complex-0.2
  - rust-opaque-debug-0.2

I'm trying to convince everyone to leave in the crago-inputs
dependencies and add a "#:skip-build? #t" to the build arguments for all
source pakages. That way we don't have to specify the transient
dependencies at the top level package. Either way yay ripgrep!

HI everyone,

I did some work on your review and have a couple questions before I submit
the next patchset.

* My questions for Martin:

> dependencies and add a "#:skip-build? #t" to the build arguments for all

I like this idea. I think I will do it if you don't mind. It's either that
or add hidden? #t to the properties, right?
Whether to add #skip-build? #t to the packages is the last piece of review
I need to fixup.

* Discussion for Nicolo:

> - rust-demo-hack <at> 0.0.5: all the source URIs are unreachable

I guix build rust-demo-hack <at> 0.0 and got the download. Maybe it was a
temporary network issue or something?

> Also:
> - rust-miniz-oxide-c-api-0.2: defined but not used

It is used by at least rust-flate2 I think.

* Work I did based on Nicolo's suggestions:

Ah, that's because I left off my first package from the patchset. It will
be included next round.

Thanks, looking forward to having ripgrep upstream :)

So the ` hidden? #t ` also hides the package from (find-packages*)
functions in (gnu packages). I actully want to be able to search for and
use rust libraries with guix, so I prefer not to hide them.

I totally agree. I can't find any documentation on #skip-build though. Can
you provide a snippet, maybe?

Thanks,

I just stumbled upon it will looking at the cargo build system
https://github.com/guix-mirror/guix/blob/master/guix/build-system/cargo.scm#L107
but you pass it just like an other build system argument. ie 

(define-public rust-afl
   ....
    (arguments
      `(#:skip-build?
        #t
        #:cargo-inputs
        (("rust-cc" ,rust-cc)
         ("rust-clap" ,rust-clap)
         ("rust-rustc-version" ,rust-rustc-version)
         ("rust-xdg" ,rust-xdg))))
    ....

Thanks Martin,

Perfect. I will work on an updated patchset and get it in as soon as I can.

I also agree on not hiding the rust libraries. IIRC it also confuses the
importer into thinking the packages aren't available and should be
imported.

Hi all,

Sorry it took a while. As it turns out, keeping #cargo-inputs and
#cargo-development-inputs was a very good idea.
It turns out I was missing about 60 more dependencies! I linted them
as far as I could without breaking anything.
I added #skip-build #t to all the other dependencies.

The only issue here is that the commit order has somewhat lost the
topological order of the dependencies because rebasing them all
required too much conflict resolution.

I rebased these on master this morning.

Thanks for all your input!

John
