Wrong src generated for a git dependency

[edofic]

I ran

pypi2nix -V "2.7" -r requirements.txt

with this as requirements.txt.

git+https://github.com/lepture/flask-oauthlib.git@33f155bb86c5482b638b7383fb360d02b11a99f1

Because I need a version at a specific commit that was never released. pypi2nix outputs the "correct" version 0.7.0 into requirements_frozen.txt - this commit still says 0.7.0 but the code is newer than the actual 0.7.0 release. The problem however is in requirements_generated.nix. This is the offending derivation:

"Flask-OAuthlib" = python.mkDerivation {
  name = "Flask-OAuthlib-0.7.0";
  src = pkgs.fetchurl {
    url = "https://pypi.python.org/packages/c4/33/6c780315d45f33bf094031330126686221f101f834f5f0035fddf5ad1aa7/Flask-OAuthlib-0.7.0.tar.gz";
    sha256 = "0389c057d7d3e5ea5f3335fd6c5c0327bc0828f534a165323836d0ecc66bdeb9";
  };
  doCheck = commonDoCheck;
  buildInputs = commonBuildInputs;
  propagatedBuildInputs = [
    self."Flask"
    self."oauthlib"
  ];
  meta = with pkgs.stdenv.lib; {
    homepage = "";
    license = licenses.bsdOriginal;
    description = "OAuthlib for Flask";
  };
};

src is pointing at pypi and picking up the actual 0.7.0 which is not the version in requirements.txt.

I got around this by providing a git source in the overrides but this has to be kept in sync manually so I'd really rather the tool does that for me.
Slightly offtopic: this is really the only override I needed for 2600 lines of generated nix code - you built an awesome tool!

@edofic happy new year!

could you try adding #egg=Flask-OAuthlib to the end of git+https://... line in requirements.txt?

if above does not fixes it would you have time to investigate it. here is where the bug might happen.

also maybe add Flask-OAuthlib to tornado example (in examples/ folder) so that we check that there will not be any regression later on.

@garbas happy new year to you too!

I tried, no diff on the generated files.
Yes, I can look into this, thanks for the pointer.
