DOC/BLD: attributes initialized as None not picked up by autosummary anymore

[jorisvandenbossche]

I already mentioned it here: #5899 (comment), but then this did not appear on the dev doc builds on the website and only locally on my computer. But now I also see it there. See eg http://pandas.pydata.org/pandas-docs/dev/generated/pandas.DataFrame.html#pandas.DataFrame in the list of attributes, the is_copy is no link anymore.

So I get the following warning: DataFrame.is_copy.rst:: WARNING: document isn't included in any toctree for 8 methods:

pandas.DataFrame.is_copy
pandas.DatetimeIndex.name
pandas.DatetimeIndex.offset
pandas.Index.asi8
pandas.Index.name
pandas.Panel.is_copy
pandas.Panel4D.is_copy
pandas.Series.is_copy

Strange thing is, there have not been recent changes to these functions (I think), but the errors only appeared recently.
@y-p You did the most recent doc build on the website? (does this not happen automatically anymore?)

[ghost]

yes I did and no it doesn't, we don't know why.

@jorisvandenbossche, are you familiar with git bisect?

[jorisvandenbossche]

Not yet, but I will try. At least first find a previous version that does not have this.

I lookes at this a couple of days ago, the original commit where you introduced _templates
already had some of these warnings.

[jorisvandenbossche]

Yes, I also tried to go back to locate the change, and noticed that even the released 0.13 and previous development versions of 0.12 have this issue If I checkout them now and run the docs. But the strange thing is, I only saw these warnings more recently in January, and never before. Also, for example the stable docs at the moment (from 0.13) don't have the issue (stable docs Series docstring), while the dev docs have (dev docs Series docstring).

So it seems that there is also something else apart from pandas that plays a role, but I shouldn't know what.

[jorisvandenbossche]

Correction, it does appear also in the stable docs, just not for Series where I linked to above for some reason, but it does for DataFrame and Index etc. But I really thought it was not the case before (as I said in my comment #5899 (comment)).

BTW, the links to the docs of 0.12 and 0.11 on the main website are dead.

That was not fun.

[jorisvandenbossche]

And has become 'worse': http://pandas.pydata.org/pandas-docs/dev/generated/pandas.Index.html. I mean, previously it was only name and asi8 in Index which had this problem, now 6 attributes. While nothing changed to the code I think.

[jreback]

do you have any idea what the problem is?

@jorisvandenbossche any fix on this?

[jorisvandenbossche]

Not yet. Should take some more time to investigate this, but it's no blocker for 0.14 I think (at least not for a first release candidate).
