setup: prevent setuptools from laying an egg Previously, test-hghave.t was failing on Windows (and on Linux if $FORCE_SETUPTOOLS was set) with the following: --- c:/Users/Matt/Projects/hg/tests/test-hghave.t +++ c:/Users/Matt/Projects/hg/tests/test-hghave.t.err @@ -19,7 +19,11 @@ > foo > EOF $ run-tests.py $HGTEST_RUN_TESTS_PURE test-hghaveaddon.t + warning: Testing with unexpected mercurial lib: c:\Users\Matt\Projects\hg\mercurial + (expected ...\hgtests.mu9rou\install\lib\python\mercurial) . + warning: Tested with unexpected mercurial lib: c:\Users\Matt\Projects\hg\mercurial + (expected ...\hgtests.mu9rou\install\lib\python\mercurial) Augie relayed concerns[1] about the first attempt at this, which also excluded 'install_egg_info'. All that needs to be excluded to avoid the egg and make the test work is to filter out 'bdist_egg'. (Actually, the body of this class could simply be 'pass', and 'bdist_egg' still isn't run. But that seems to magical.) Also note that prior to this (and still now), `make clean` doesn't delete the 'mercurial.egg-info' that is generated by `make install`.
