Default settings for development do not work nicely with pypi

[Letme]

I have a simple project and the deployment to test-pypi is done via .travis-ci.yml for each commit on master branch. The problem is the below error and after reading the documentation couple of times is that I do not know how to switch to SimVer.

Probably my question is more in line of how to make this pypi compatible (what to add into setup.py) as the default is just not working for non-tagged deployment.

Error from travis-ci:

HTTPError: 400 Client Error: '0.0.11.dev14+g0f7c142' is an invalid value for Version. Error: Cannot use PEP 440 local versions. see https://packaging.python.org/specifications/core-metadata for url: https://test.pypi.org/legacy/

pypi rejects local versions by design, and setuptools_scm explots that fact in a way (preventing the uploading of randomc scm versions to pypi as a stopgap in release processes)

if you want to work that in more detail you can either reconfigure setuptools_scm in setup.py to stop protecting you from that or you can alter the pypi deployment to set up a env varible in SETUPTOOLS_SCM_PRETEND_VERSION

[Letme]

Can you point me to how to reconfigure setuptools_scm in setup.py to stop protecting me from that?

[RonnyPfannschmidt]

for example you can use local_scheme of https://github.com/pypa/setuptools_scm#configuration-parameters and set it to 'dirty-tag'

aka

setup(
   ...,
   use_scm_version = {'local_scheme':'dirty-tag'},
   ...,
)```

[RonnyPfannschmidt]

note, i suggest to only set that on travis in order to prevent personal mistakes in the release process

[Letme]

If I use SETUP_TOOLS_SCM_PRETEND_VERSION, then I can probably use it in master only and let default stay for the tags?

Then something like {next_version}.dev{distance} would work correct?

[Letme]

That fits nicely with your note as well (since otherwise I have to pipe in some stuff in travis)

[RonnyPfannschmidt]

off hand no idea, i usually use the default setup, and upload dev releases to a devpi instance

Is this the sort of information that should go into pypi/warehouse#3153?

[RonnyPfannschmidt]

@brainwane possibly

closing this one as not actionable, the defaults are intentionally not upload friendly and can be configured away with a different sceme
