[PATCH 0/5 v2] Proposed docs version changes

[Richard Purdie]

I've tweaked my patchset with some review feedback from Quentin. The v2:

* uses yaml to load the variables in conf.py
* fixes a bitbake_mapping[i] -> branch
* fixes a comment typo in set_versions.py
* comments the bitbake langdale version mapping

[PATCH 1/5] Makefile/set_versions: Allow poky.yaml to be autogenerated

[Richard Purdie]

Use a script to generate the branch/tag information inside poky.yaml.

If the branch isn't a known release branch, include git magic to find
the closest matching release branch we know about.

This is technically not an issue because open("poky.yaml", "w") 
overwrites the file if it already exists.

Though, we should make sure the run-docs-build script in 
yocto-autobuilder-helper repo actually runs git clean -ffdx before 
checking out another branch otherwise there can be a conflict because 
poky.yaml exists locally and would be overridden/overwritten by 
poky.yaml from an earlier release and fail the checkout. IIRC Richard 
had that in his patch so we should be good.

I feel like a fixup patch is just fine, does not seem to be a blocker?

Cheers,
Quentin

[PATCH 2/5] conf.py/set_versions/poky.yaml: Set version in conf.py from poky.yaml

[Richard Purdie]

Allow conf.py to read the versions it needs from poky.yaml and have
set_versions.py write this out. This means we don't have to change as
many files when making new releases.

[PATCH 4/5] set_versions/switchers.js: Allow switchers.js version information to be autogenerated

[Richard Purdie]

A horrible blunt hammer approach to updating the version information in
switchers.js based on the available tag information.

To merge and work correctly, this will need a change to the autobuilder-helper
docs generation code to pull the swicthers.js and script from master, then
to run the script. That should hopefully remove the need for other patching
even on old docs branches though.

[PATCH 5/5] set_versions: Various improvements

[Richard Purdie]

- Allow specifying the version from the commandline
- Add all previous release series/version mappings (to support transitions branch)
- Add poky mapping for 3.4 as some releases erronously use it
- Improve git branch 'guessing' code to work properly
- Handle poky '.0' release mappings correctly
- Only write poky.yaml if poky.yaml.in exists
- Ensure older non-active releases are shown in the switchers.js
  release list.
- Ensure current version and current release series are shown in switcher.

Would it make sense to implement what you have in set_versions.py directly
in Sphinx 'native' code ? e.g. directly in conf.py, or in a module loaded
from conf.py (see how kernel does it at [1]) or yocto-vars extension, or as
its own Sphinx extension?

poky.yaml only purpose is to be loaded by yocto-vars.py which is a local
Sphinx extension we created.

Agreed. I don't think this patch series makes the doc building situation 
worse than it currently is so there's no reason to hold it off. Makes it 
even easier on stable release maintainers so it's good :)

I just would like the behavior to be unchanged wrt versions listed in 
the switchers.js, the rest is fine and can be modified later on.

Which versions are listed in switchers.js can be modified in a separate 
commit to start the discussion (or at least have a "note" somewhere to 
explain what are the expectations).

Cheers,
Quentin

Just to be clear, you mean adding gatesgarth and zeus back?
Or adding the current version and the current version series?

I'm going to assume we're talking about the first and I'll redo things to try
and do that. I've decided I'd better retest everything having done that with the
side be side comparison so it may take a while :/.

Richard

Keeping the current behavior which is the latest dot version of all 
releases up to Warrior.

dev
3.4.2
3.3.5
3.2.4
3.1.14
3.0.4
2.7.4

is what I currently have.

Quite unfortunate...

We could have 3.0.4 and 2.7.4 hardcoded in switchers.js and use git tags 
for the rest?

These tags are in place. I back-dated them to the release day but I put
them in my name since I've added these without a release engineer involved.
