From Python

From python3's toplevel:

Remote

project = 'hello'
# remote repository
origin_url = 'https://www.mercurial-scm.org/repo/%s' % project
# local clone
directory = '/home/storage/hg/repo/%s' % project

import logging
logging.basicConfig(level=logging.DEBUG)

from swh.loader.mercurial.tasks import LoadMercurial

t = LoadMercurial()
t.run(origin_url=origin_url, directory=directory, visit_date='2016-05-03T15:16:32+00:00')

local directory

Only origin, contents, and directories are filled so far.

Remaining objects are empty (revision, release, occurrence).

project = '756015-ipv6'
directory = '/home/storage/hg/repo/%s' % project
origin_url = 'https://%s.googlecode.com' % project

import logging

from swh.loader.mercurial.tasks import LoadMercurial

t = LoadMercurial()
t.run(origin_url=origin_url, directory=directory, visit_date='2016-05-03T15:16:32+00:00')

local archive

project = '756015-ipv6-source-archive.zip'
archive_path = '/home/storage/hg/repo/%s' % project
origin_url = 'https://%s-archive.googlecode.com' % project

import logging
