pick up version number from tag

[jsturdy]

Motivation and Context

Makes sure versions come from the tag and number of commits since last tag. Allows uniformly sequential builds to be built.

How Has This Been Tested?

Tested make rpm with a final, preliminary, and untagged commit

[mexanick]

could you please elaborate more on "final", "preliminary" and "untagged" commits? or, maybe we can get some kind of doc extending your manifest?

[jsturdy]

the logic is roughly laid out in tag2rel.sh

• untagged: no tag currently exists in git tree
• preliminary: vre='^v?(\.)?([0-9]+)\.([0-9]+)\.([0-9]+)-(alpha|beta|pre|rc)[0-9]+'
  • here pre and rc will be treated identically (due to how setuptools rewrites some things...) so the numbers attached should be strictly increasing
  • to adhere to this i am thinking of enforcing something like the folowing:
  • make a number of pre tags, ending with vX.Y.Z-preN
  • get to a place where a rc distinction makes sense and from this point on (vX.Y.Z-rcN+1), only rc should appear in the tag (granted, I don't expect in main production we'll get a lot of different tags in these categories, probably mostly around the time we make API/ABI changes and bump major or minor versions)
• final: vre='^v?(\.)?([0-9]+)\.([0-9]+)\.([0-9]+)'

I haven't fully tested this through all thec++/arm compilation, but if they're getting their version info from the variables, they should be OK Verified

[jsturdy]

Caveat, every subpackage will have the same version, as it will be obtained from the tag (probably fine, just something to be aware of)

[mexanick]

if no outstanding todos, please rebase and merge

Now also builds <package>-devel RPMs
