The easy_install caches information about servers to reduce network
access. To see the update, we have to call the clear_index_cache
function to clear the index cache:
>>> zc.buildout.easy_install.clear_index_cache()
If we run build with newest set to False, we won't get an update:
>>> zc.buildout.easy_install.build(
... 'extdemo', dest,
... {'include-dirs': os.path.join(sample_buildout, 'include')},
... links=[link_server], index=link_server+'index/',
... newest=False)
'/sample-install/extdemo-1.4-py2.4-linux-i686.egg'
>>> ls(dest)
d demo-0.3-py2.4.egg
d demoneeded-1.1-py2.4.egg
d extdemo-1.4-py2.4-unix-i686.egg
But if we run it with the default True setting for newest, then we'll
get an updated egg:
>>> zc.buildout.easy_install.build(
... 'extdemo', dest,
... {'include-dirs': os.path.join(sample_buildout, 'include')},
... links=[link_server], index=link_server+'index/')
