Yeah, I'm quite religious about making sure my commits have been through
pgindent already (mainly to reduce subsequent "git blame" noise).
However, relying on manual updates to the in-tree typedefs.list only
works if every committer is equally religious about it. They're not;
else we'd not be having this discussion. The workflow I describe above
is not dependent on how careful everybody else is, which is why I
prefer it.
I think that the main new idea that's come out of this thread so far
is that very frequent reindents would be as good, maybe better, as
once-a-year reindents in terms of the amount of rebasing pain they
cause for not-yet-committed patches. If we can fix it so that any
mis-indented commit is quickly corrected, then rebasing would only be
needed in places that were changed anyway. So it seems like that
would be OK as a new project policy if we can make it happen.
However, I don't see any way to make it happen like that without
more-or-less automated reindents and typedefs.list updates,
and that remains a bit scary.
I did just have an idea that seems to ameliorate the scariness
a good bit: allow the reindent bot to auto-commit its results
only if the only lines it's changing are ones that were touched
by commits since the last auto-reindent. Otherwise punt and ask
a human to review the results. Not sure how hard that is to
implement, though.
Another good safety check would be to not proceed unless the latest
typedefs list available from the buildfarm is newer than the last
commit --- then we won't mess up recent commits whose typedefs are
not in the list yet.
