From: Brian Warner Date: Wed, 4 Mar 2015 02:19:58 +0000 (-0800) Subject: tahoe cp: overhaul target assignment, update tests X-Git-Tag: allmydata-tahoe-1.10.1a1~60^2~8 X-Git-Url: https://git.rkrishnan.org/pf/content/en/seg/about.html?a=commitdiff_plain;h=2a361bc46ffa26b5f6cb25b7130d99870d2fa718;p=tahoe-lafs%2Ftahoe-lafs.git tahoe cp: overhaul target assignment, update tests This substantially changes the internals of "tahoe cp", to behave in accordance with the scheme developed in ticket:2329. test_cli_cp.py got a large new test to exercise all the various combinations. This also changes the set of error messages that "tahoe cp" can produce. This modifies try_copy(), inserts a new implementation of copy_things_to_directory() (and supporting methods), and fixes a few bugs elsewhere. fixes ticket:2329 --- diff --git a/src/allmydata/scripts/tahoe_cp.py b/src/allmydata/scripts/tahoe_cp.py index 0498cee9..850a1b37 100644 --- a/src/allmydata/scripts/tahoe_cp.py +++ b/src/allmydata/scripts/tahoe_cp.py @@ -2,6 +2,7 @@ import os.path import urllib import simplejson +from collections import defaultdict from cStringIO import StringIO from twisted.python.failure import Failure from allmydata.scripts.common import get_alias, escape_path, \ @@ -12,7 +13,7 @@ from allmydata.util import fileutil from allmydata.util.fileutil import abspath_expanduser_unicode, precondition_abspath from allmydata.util.encodingutil import unicode_to_url, listdir_unicode, quote_output, \ quote_local_unicode_path, to_str -from allmydata.util.assertutil import precondition +from allmydata.util.assertutil import precondition, _assert class MissingSourceError(TahoeError): @@ -156,7 +157,9 @@ class LocalDirectoryTarget: return self.children[name] pathname = os.path.join(self.pathname, name) os.makedirs(pathname) - return LocalDirectoryTarget(self.progressfunc, pathname) + child = LocalDirectoryTarget(self.progressfunc, pathname) + self.children[name] = child + return child def put_file(self, name, inf): precondition(isinstance(name, unicode), name) @@ -337,6 +340,7 @@ class TahoeDirectoryTarget: self.children = None def just_created(self, writecap): + # TODO: maybe integrate this with the constructor self.writecap = writecap self.readcap = uri.from_string(writecap).get_readonly().to_string() self.mutable = True @@ -482,57 +486,83 @@ class Copier: return 1 def try_copy(self): + """ + All usage errors are caught here, not in a subroutine.
