Description
A combination of a slower machine and the git history getting really large results in a confusing error when building from a freshly cloned repository. My first instinct when seeing the 40 second timeout was that something was hanging, but it looks like this was actually just a too-short timeout threshold.
We should either:
- Increase the timeout (but this is a moving target)
- Put a
git statusin the development installation instructions - Make the error message more helpful
Steps to reproduce:
- Clone the repository (do not run
git status) - Build from source
setuptools_scmerror, which results from a 40 second timeout- Run
git status, which will refresh the git index (10-20 second task) - Building from source does not time out now
