problems with GIT_DESCRIBE_NUMBER

[elehcim]

Hello, my recipe is like:

package:
  name: pkg
  version: {{ GIT_DESCRIBE_TAG }}

source:
  git_url: .
  git_rev: conda_pkg

build:
  number: {{ GIT_DESCRIBE_NUMBER }}
...

and is located in a git repo.

user@machine:pkg_git $ git status
On branch conda_pkg
Your branch is up-to-date with 'origin/conda_pkg'.
nothing to commit, working directory clean

If I perform a conda build ., this error is produced:

Traceback (most recent call last):
  File "/home/user/anaconda3/bin/conda-build", line 5, in <module>
    sys.exit(main())

    return int(self.get_value('build/number', 0))
ValueError: invalid literal for int() with base 10: ''

If I substitute:

build:
  number: {{ GIT_DESCRIBE_NUMBER }}

with

build:
  number: 0

it works and the package created is something like pkg-v0.2.2-76_g869cb67.tar.bz2

Stepping into /home/user/anaconda3/lib/python3.5/site-packages/conda_build/metadata.py:454 it seems that GIT_DESCRIBE_NUMBER is None...

Do you have any idea on why GIT_DESCRIBE_NUMBER is not working?
Thanks

What does git describe --tag show?

How do you create your tags? If you are not annotating them, there might be issues. Note that tags created via the github web interface are lightweight, not annotated tags.

https://git-scm.com/book/en/v2/Git-Basics-Tagging#Annotated-Tags

To retroactively annotate tags:

git checkout <lightweight tag tagged via github>
git tag -a <same tag name>
<enter description/notes>
git push <github repo> --tags

If this does not work, then we have a bug, but I think this is the issue - we test this functionality in our integration tests, and have not seen an issue with the 1.21.3 release.

$ git describe --tag
v0.2.2-78-g3845222

v0.2.2 is annotated

[msarahan]

OK, are these public repos (the source, and the recipe) that I can clone for debugging purposes?

[elehcim]

No, I've created a repo here: https://github.com/elehcim/conda_git_dbg.git for which I can reproduce the issue.

$ conda create -n git_tag python
$ source activate git_tag
$ cd conda_git_dbg
$ git checkout conda_dbg
$ git describe --tag
ttt-1-g628dfb0
$ conda build .
Cloning into '/home/user/anaconda3/conda-bld/work'...
done.
Switched to a new branch 'conda_pkg'

I've found a workaround. Changing to:

build:
  number: {{ environ.get('GIT_DESCRIBE_NUMBER', 0)}}

works.

[msarahan]

OK, thanks. That's helpful for debugging, though it should work either way. I'll update the tests and make sure.

[elehcim]

maybe related to #357 ?

[msarahan]

This should be fixed in conda-build 1.21.4, released yesterday. Closing this issue for now, but please reopen or comment here if you still have issues.
