It seems that the more you dig into piling changes on this topic
there is somebody else who comes back with yet another corner case.
At this point in the release cycle, I am inclined to say that we
should revert the whole thing from 2.8-rc. Even with that plan, we
probably need an extra rc as the reverting a topic this late in the
cycle is something I feel uncomfortable with.
What is the ultimate goal of nd/exclusion-regression-fix topic over
the behaviour before 2.7.0 and after 2.7.1 (there was a regression
in 2.7.0 that was reverted in 2.7.1)? From the cover letter of the
series:
Take one was bad and reverted in commit 8c72236. Take two provides a
more complete solution to the pair of rules
exclude/this
!exclude/this/except/this
3/4 should do a better job at stopping regressions in take 1. 4/4
provides the solution. I think I have tested (and wrote tests) for all
the cases I can imagine.
"solution to the pair of rules" hints there are some problem in the
pair of rules, without stating what it is trying to solve.
Isn't the root cause of the issue that treat_one_path() when
deciding if it is worth descending into a directory check if the
directory itself is excluded and returns path_excluded, even if some
paths inside it may have a countermanding ! entries that would match
them? What if we change that part smarter and allow it to descend?
