Support pre-1.0 versions #139
Description
The Version class (at a minimum, probably elsewhere) requires the major version number to be at least 1. That makes it hard to set up test dbprocessing chains using pre-1.0 codes.
Relation to an issue
None
Proposed enhancement
It should be fairly straightforward to just remove the checks and allow major version to be zero.
Alternatives
Keep the current state. It's not clear it was a carefully considered design decision; there's just a note that goes back to 6e97bfa and the actual check goes back to the first commit of 2220578
@balarsen do you remember this?
OS, Python version, and dependency version information:
Linux-6.5.0-28-generic-x86_64-with-glibc2.38
sys.version_info(major=3, minor=11, micro=6, releaselevel='final', serial=0)
sqlalchemy=1.4.47
Version of dbprocessing
Current main.
Closure condition
This issue should be closed when either this is abandoned, or we have checked-in passing tests that use major versions of zero in code and files.
