Bower resolution doesn't work

Bower supports resolutions if two packages
are declared with different versions. bower2nix fails to account for that.

A http://sscce.org/: https://gist.github.com/domenkozar/c1a3dbc9ab86c867aa356ea6218533e0

Note that you have to use bower2nix from master:

git clone https://gist.github.com/c1a3dbc9ab86c867aa356ea6218533e0.git
cd c1a3*
bower2nix > bower-generated.nix && nix-build bower.nix

If you remove the last commit, you'll see that it also doesn't work without resolutions

@rvl

fetchbower is not deterministic

Issue description

After using bower2nix to generate bower-generated.nix, I get the following error when running a nix-build on my expression:

output path ‘/nix/store/lbn3c6i5v62xqi8mk2dfy54vi8mgzkli-angular-block-ui-0.2.2’ has r:sha256 hash ‘09sccghl6mbn32bai6bsa47mw3vibkdnzginc4y62hkx5wks42rk’ when ‘0nzqan0mqj47qic7m74d2rwp178n2wgjw523hw9x2mfnrcicsyvp’ was expected

and the hash is different time I run nix-build!

Steps to reproduce

The problem is easily reproducible.

1- I have the followingbower-generated.nix:

{ fetchbower, buildEnv }:
buildEnv { name = "bower-env"; ignoreCollisions = true; paths = [
    (fetchbower "angular-sweetalert" "1.1.0" "1.1.0" "060wmhivpb257xxa4lg9jznnqn9w7rfk5cvx5513pzfmm5clqw4z")
    (fetchbower "satellizer" "0.14.1" "0.14.1" "00m566lq6ajknxfvlnz65b4wqr4j6cc6vvsym3jbbf8rnss35yha")
    (fetchbower "angular-block-ui" "0.2.2" "0.2.2" "0nzqan0mqj47qic7m74d2rwp178n2wgjw523hw9x2mfnrcicsyvp")

    (fetchbower "ngstorage" "0.3.6" "0.3.6" "06y7y0j6igp6w42kh8msbjfnqs1555jxnw4kq6hcl9s8145a0864")
    (fetchbower "angular-smart-table" "2.1.8" "2.1.8" "0yjld9sinx1hxgc28qs8q0dc6xfvf14bdm88zzrwmcdyaggjwf0a")

    (fetchbower "angular-ui-router" "0.2.18" "0.2.18" "02xvdn93wfzya6fb6srnk2175hgdkpdwxpnybrsl1yz0j05vphs0")
    (fetchbower "angular-google-chart" "0.1.0" "0.1.0" "16gyw7ww5v2ks43gixg7vfynjgm8xar9h77dkvd1ml2r0z2brc73")
    (fetchbower "jquery" "2.2.4" "2.2.4" "0jir5x9xgkkpql5kwfclg9j4lpysg9dbkq8qbp5j0384kn23d9x8")
    (fetchbower "angular" "1.5.3" "1.5.3" "010fhrgfh8ykwfkyxpndadkpzl72dgy3yr4j83jp3nwpjismnbmg")
    (fetchbower "angular-ui-bootstrap" "1.3.2" "1.3.2" "06rfib7mlgbnlaniyb76w1gqzg5s1hccpzv5hbqwhvvk38fyqkgw")

  ];
}

2- And this default.nix:

{ pkgs ? import <nixpkgs> {} 
, mySource ? ./.
, system ? builtins.currentSystem
}:
with import <nixpkgs> { inherit system; };
let
  bowerPackages = import ./bower-generated.nix { inherit (pkgs) fetchbower buildEnv; };
in
{
  bowerComponents = pkgs.stdenv.mkDerivation {
    name = "bower_components";
    inherit bowerPackages;
    src = mySource;
    buildPhase = ''
      cp -RL --reflink=auto ${bowerPackages} bc
      chmod -R u+w bc
      HOME=$PWD bower \
        --config.storage.packages=bc/packages \
        --config.storage.registry=bc/registry \
        --offline install
    '';
    installPhase = "mv bower_components $out";
    buildInputs = [ pkgs.git bowerPackages pkgs.nodePackages.bower ];
  };
}

3- Command that is run:

$ nix-build

Technical details

• System: OSX El Capitan v 10.11.5
• Nix version: (Nix) 1.11.2
• Nixpkgs version: 16.03.1011.6317da4

) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: Invalid endpoint

using bower2nix 3.2.0 with https://github.com/xwiki-labs/cryptpad/blob/38a1e5e39fb854cdbad8896333901beb85ee6510/bower.json results in this error:

(node:26837) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: Invalid endpoint: #^1.6.0

it seems this is a feature which is not supported in bower2nix.

hack

if this patch is applied, it is working:

     "html2canvas": "^0.4.1",
     "croppie": "^2.5.0",
-    "sortablejs": "#^1.6.0",

Error: spawn nix-hash ENOENT

I tried using bower2nix as follows in a directory containing bower.json:

nix-shell --pure -p nodePackages.bower2nix
bower2nix > bower-generated.nix

The content of bower-generated.nix:

# Generated by bower2nix v3.2.0 (https://github.com/rvl/bower2nix)

]; }

Any ideas what's wrong?

ENOCACHE No cached version for

I'm not able to generate a nix expression that would work with nix-rebuild so I thought I'd ask here if I'm doing something wrong or if there's something wrong in bower2nix.

With original file

The original bower.json file looks like:

{
  "name": "nextcloud-calendar",
  "dependencies": {
    "angular": "1.6.4",
    "angular-bootstrap": "2.5.0",
    "jquery-timepicker": "883bb2cd94",
    "jstzdetect": "https://github.com/georgehrke/jstimezonedetect.git",
    "ical.js": "1.2.2",
    "fullcalendar": "3.4.0",
    "hsl_rgb_converter": "https://github.com/kayellpeee/hsl_rgb_converter.git"
  },
  "devDependencies": {
    "angular-mocks": "1.6.4"
  }
}

The result of bower2nix:

Clean GitHub URLs

Based on this comment: #9 (comment) , I thought I need to clean the GitHub URLs. So I tried that:

Conclusion

I'm out of ideas and very lost here. Any ideas what I'm doing wrong?

move to nix-community org?

seeing as this repo hasn't seen updates in a while, it would seem like it could use more maintainers.
would it perhaps be an idea to have the repo moved to the nix-community org such that people could more easily contribute to it?

bower2nix includes ~ in generated versions

E.g. for a bower.json such as this:

{
  "name": "jupyter-notebook-deps",
  "version": "0.0.1",
  "dependencies": {
    "backbone": "components/backbone#~1.2",
    "bootstrap": "components/bootstrap#~3.3",
    (snip)
  }
}

...the generated .nix file will include ~ in the version number:

 (fetchbower "backbone" "components/backbone#~1.2" "components/backbone#~1.2" "1arcv99907bzr84lfrm9qyv0l8al653p6m4ih188n2dz8dd7n6ls")
 (fetchbower "bootstrap" "components/bootstrap#~3.3" "components/bootstrap#~3.3" "1vf8wylj51dh3gkjasnifpycvsfaxjci9hj4vd5q028ck7fprk8g")

Not only does this break bowerVersion, but it would also make the fetch non-fixed in the event that bowerVersion were fixed.

You do handle ~-ranges correctly in other cases; at the moment, I suspect it's the hash that's throwing it off.

fetchbower: support for git repositories

bower2nix generates following line for a git repository:

(fetchbower "purescript-prim" "hdgarrood/purescript-prim" "hdgarrood/purescript-prim" "0434lf7pkmpyb9pn3yjppmj9mqnx064xaqmjlrcq1vkbwn69n50c")

And then when building the bower project, Nix fails with:

error: invalid character ‘/’ in name ‘purescript-prim-hdgarrood/purescript-prim’

Sounds like an easy fix, but haven't looked into it yet.

Handle relative paths

For example if bower.json contains:

...
"purescript-avm-bridge": "../web-bridge",
...

Then building results into:

error: invalid character ‘/’ in name ‘purescript-avm-bridge-../web-bridge’

cc @rvl

Invocation of example app takes nearly a minute

{
  "name": "my-web-app",
  "dependencies": {
    "angular": "~1.5.0",
    "bootstrap": "~3.3.6"
  }
}

What could be the cause?

3.2.0 generates wrong hashes

Coming back to our friend uchiwa, there are still issues. When running bower2nix, I get hash mismatches when trying to build the package:

output path ‘/nix/store/yyvvlc769izfa0ssdal2g4n0aksmcvdc-uchiwa-web-0.26.1’ has 
r:sha256 hash ‘1n4a7inanshh5bxz1c5lwddqyky4innzifzyxvvyjygawg93vi8m’ when 
              ‘13zglwrlba538iqlxmyhfcq51y8xd6d7clnixxqk0zg53ns36cp6’ was expected

The easiest way to try it out is to:

1. Run bower2nix 3.2.0
2. Check out nixpkgs
3. Run pkgs/servers/monitoring/uchiwa/update.sh
4. Run nix-build -A uchiwa $(pwd)

Does not work on Node 12

I don't really know a lot about nodejs but the error seems to be because of an old fs-extra version.

Fails with packages legitimately containing slashes

Later versions of https://github.com/sensu/uchiwa use angular-tools/ng-jsoneditor and while bower2nix will process bower.json, nix will subsequently fail with:

error: invalid character ‘/’ in name ‘angular-tools/ng-jsoneditor-ea138469f157d8f2b54ec5b8dcf4b08a55b61459

bower-packages.json:

SyntaxError: Unexpected strict mode reserved word when trying to run under NixOS

Hi!

I'm trying to test your updated version of bower2nix (version 3.0.1) on my NixOS machine, and while it builds via default.nix, I cannot get it to run after installing the derivation. I get the following error when running bower2nix -v:

I am not very familiar with TypeScript (or JS for that part), so I think I need some help with debugging this. Any pointers? And thank you for your efforts to make bower2nix a useful tool with decent documentation!

Sync docs with https://nixos.org/nixpkgs/manual/#ssec-bower2nix-usage

For example pkgs.stdenv.mkDerivation in README needs to be pkgs.buildBowerComponents.

In default.nix, I use:

 bowerComponents = pkgs.buildBowerComponents {
    name = "nextcloud-calendar-bower";
    generated = ./js/bower-generated.nix;
    src = ./js;
  };

But I get an error when launching nix-shell:

error: invalid character ‘:’ in name ‘jstzdetect-https://github.com/georgehrke/jstimezonedetect.git’

Am I doing something wrong or any ideas what is the issue? Should I write those GitHub URLs differently?

No release for 3.3.0 as it hasn't been tagged

Latest available release which is also what we have in nixpkgs is 3.1.1 while 3.3 exists upstream.

fetch-bower not resetting `expires` field

Building fetchbower for package bootstrap-tour is non-deterministic (and thus build fails).

To reproduce this run

nix-build -E 'let pkgs = import <nixpkgs> {}; in  (pkgs.fetchbower "bootstrap-tour" "0.11.0" "0.11.0" "0sfacwp1awvk93s6a5al1385dixblyizgp8dymnwzkac5mg1x01x")' 

And observe the output. There is a hash mismatch. Now run it again, resulting hash will be yet another value.

I ran nix-build with -K and analysed resulting dirs. Here is the culprit part of the diff

--- a/nix-build-bootstrap-tour-0.11.0.drv-0/out/registry/bower.herokuapp.com/lookup/bootstrap-tour_62fe9

Value for expires is different. I found this bit of fetchbower that is supposed to set it to 0 but apparently it doesn't work in this case (it does work for all other packages I have).

This is as far as I got. I can probably invest some more time into fixing this in the near future if need be.
