setup: prevent setuptools from laying an egg
I just ran this patch by dstufft (the pip maintainer), and he strongly
suspects (without having tested) that this will break `pip list` for
Mercurial. Also, he said this:
14:21 < dstufft> durin42: I think if you do ``mkdir -p src && mv
mercurial src/``
and patch setup.py to add ``package_dir={"": "src"},``
it'll
resolve that for you
14:22 < dstufft> durin42: the problem you're going to run into, is stuff
depends
on that .egg-info, even though it says egg in the name
still,
that's still a part of modern packaging, and the reason
why it
was picking up local-source-tree hg is likely going to
be
because python adds ``.`` to sys.path at the very front
So we should probably find some other workaround here. :(
Bafflingly, an empty install class lets the test work, but does not
prevent the generation of .egg-info:

Alternately, adding --local to that test will cause the error to be
skipped [1]. (It ends up using hg from the source tree.) But I didn't do
that, thinking that undermining the check was the wrong way to go. I
assume if we keep generating eggs, `make clean` should get rid of it.
Regarding your previous email about finding a way to not 'cd' back to the
source tree, I don't think that's what is happening. PYTHONPATH when hg
is installed for the internal test is:
C:\Users\Matt\AppData\Local\Temp\hgtests.ijjckm\install\lib\python;$TESTTMP;c:\Users\Matt\Projects\hg\tests;c:\Users\Matt\Projects\hg;c:\Users\Matt\Projects\hg\tests;c:\Users\Matt\Projects\hg\tests
(Interesting, that repetition at the end.)
self._installdir for the internal test matches that first path. I assume
that when the egg is installed, there's nothing found there, and it simply
falls back to the source tree. When I use the empty install class and
print 'actualhg' in that check, it _does_ use the temp installed package
instead of falling back to the source tree. So while the empty class is a
bit of black magic, I think it keeps us where we are without setuptools.

Also, `make install` was creating an *.egg-info in the local Mercurial
source
tree, which `make clean` wasn't deleting.
Someone familiar with setuptools should take a close look at this. I
originally
registered a subclass of 'install_egg_info' with an empty run(), which
took care
of the egg-info generated by `make install`. Looking at the output of
setup.py
as run by run-tests._installhg(), I saw that 'bdist_egg' was being
run. I
registered a similar empty class for that command, but the egg was still
produced. But when I registered this 'install' subclass with nothing
but a
run() that called the super class run, 'bdist_egg' was no longer being
called,
and the test worked. Subsequently dropping everything except the
'install'
subclass with a minimal delegating run() allowed the test to run
(though the
setup log had output from running 'install_egg_info').
To be on the safe side (and to avoid output about eggs when the empty
subclasses
would have prevented any egg processing), I added a filter to
get_sub_commands()
to filter out the egg related stuff. Unlike the others, 'bdist_egg' is
part of
setuptools, so registering a subclass and still working without
setuptools
probably isn't very clean.
