I have been experimenting with the pkg.client.api API to get the
expected disk usage for the installer, given a set of packages. There
are no examples in the documentation, which is in "pydoc
pkg.client.api", but I came up with this (some code removed):
api_inst = api.ImageInterface(img_dir, CLIENT_API_VERSION,
progresstracker, None, PKG_CLIENT_NAME)
api.image_create(PKG_CLIENT_NAME, CLIENT_API_VERSION, img_dir,
IMG_TYPE_ENTIRE, False,
repo_uri="http://ipkg.sfbay/dev";,
progtrack=progress.QuietProgressTracker(), mirrors = mirrors,
force=True)
image_create() returns an ImageInterface object for the image that was
created, so there's no reason for the first assignment line.
The first line you have would only be used if the image already
existed, and the image_create() only if the image did not already exist.
Well, if I omit the ImageInterface call, this assertion results:
Traceback (most recent call last):

Updated code:
api.ImageInterface(img_dir, CLIENT_API_VERSION, progresstracker, None,
PKG_CLIENT_NAME)
api_inst = api.image_create(PKG_CLIENT_NAME, CLIENT_API_VERSION,
img_dir, IMG_TYPE_ENTIRE, False, repo_uri="http://ipkg.sfbay/dev";,
progtrack=progress.QuietProgressTracker(), mirrors = mirrors, force=True)
api_inst.plan_install(pkglist,refresh_catalogs=True,noexecute=False,verbose=True,
update_index=True)
plan = api_inst.describe()
new_pkg_list = [dest.fmri for src, dest in plan.get_changes()]
ret = api_inst.info(new_pkg_list, False, frozenset([api.PackageInfo.SIZE]))
pis = ret[api.ImageInterface.INFO_FOUND]
size = 0;
for i, pi in enumerate(pis):
size = size + pi.size
Also, how is "pkg_client_name" used? What should it be?
Thanks,
William
