This is safer: in the earlier API, an old webapi server would silently ignore
the initial children, and clients trying to set them would have to fetch the
newly-created directory to discover the incompatibility. In the new API,
clients using t=mkdir-with-children against an old webapi server will get a
clear error.
instead of creating an empty file and then adding the children later.
This should speed up mkdir(initial_children) considerably, removing two
roundtrips and an entire read-modify-write cycle, probably bringing it down
to a single roundtrip. A quick test (against the volunteergrid) suggests a
30% speedup.
test_dirnode: add new tests to enforce the restrictions that interfaces.py
claims for create_new_mutable_directory(): no UnknownNodes, metadata dicts
interfaces.py: define INodeMaker, document argument values, change
create_new_mutable_directory() to take dict-of-nodes. Change
dirnode.set_nodes() and dirnode.create_subdirectory() too.
nodemaker.py: use INodeMaker, update create_new_mutable_directory()
client.py: have create_dirnode() delegate initial_children= to nodemaker
dirnode.py (Adder): take dict-of-nodes instead of list-of-nodes, which
updates set_nodes() and create_subdirectory()
web/common.py (convert_initial_children_json): create dict-of-nodes
web/directory.py: same
web/unlinked.py: same
test_dirnode.py: update tests to match
invoked with the new MutableFileNode and is supposed to return the initial
contents. This can be used by e.g. a new dirnode which needs the filenode's
writekey to encrypt its initial children.
create_mutable_file() still accepts a bytestring too, or None for an empty
file.
I would prefer to have just source code, or indications of what 3rd-party packages are required, under revision control, and have the build process generate o
r acquire the binaries as needed. Also, having these in our release tarballs is interfering with getting Tahoe-LAFS uploaded into Ubuntu Karmic. (Technicall
y, they would accept binary modules as long as they came with the accompanying source so that they could satisfy their obligations under GPL2+ and TGPPL1+, bu
t it is easier for now to remove the binaries from the source tree.)
In this case, the binaries are from the tahoe-w32-client project: http://allmydata.org/trac/tahoe-w32-client , from which you can also get the source.

We need to carefully document the licence of figleaf in order to get Tahoe-LAFS into Ubuntu Karmic Koala. However, figleaf isn't really a part of Tahoe-LAFS per se -- this is just a "convenience copy" of a development tool. The quickest way to make Tahoe-LAFS acceptable for Karmic then, is to remove figleaf from the Tahoe-LAFS tarball itself. People who want to run figleaf on Tahoe-LAFS (as everyone should want) can install figleaf themselves. I haven't tested this -- there may be incompatibilities between upstream figleaf and the copy that we had here...
That version of darcsver emits a scary error message when the darcs executable or the _darcs subdirectory is not found.
This error is hidden (unless the --loud option is passed) in darcsver >= 1.3.1.
Fixes#788.
This makes it more obvious that the Helper currently generates leases with
the Helper's own secrets, rather than getting values from the client, which
is arguably a bug that will likely be resolved with the Accounting project.
child of the client, access with client.downloader instead of
client.getServiceNamed("downloader"). The single "Downloader" instance is
scheduled for demolition anyways, to be replaced by individual
filenode.download calls.
* stop using IURI as an adapter
* pass cap strings around instead of URI instances
* move filenode/dirnode creation duties from Client to new NodeMaker class
* move other Client duties to KeyGenerator, SecretHolder, History classes
* stop passing Client reference to dirnode/filenode constructors
- pass less-powerful references instead, like StorageBroker or Uploader
* always create DirectoryNodes by wrapping a filenode (mutable for now)
* remove some specialized mock classes from unit tests
Detailed list of changes (done one at a time, then merged together)
always pass a string to create_node_from_uri(), not an IURI instance
always pass a string to IFilesystemNode constructors, not an IURI instance
stop using IURI() as an adapter, switch on cap prefix in create_node_from_uri()
client.py: move SecretHolder code out to a separate class
test_web.py: hush pyflakes
client.py: move NodeMaker functionality out into a separate object
LiteralFileNode: stop storing a Client reference
immutable Checker: remove Client reference, it only needs a SecretHolder
immutable Upload: remove Client reference, leave SecretHolder and StorageBroker
immutable Repairer: replace Client reference with StorageBroker and SecretHolder
immutable FileNode: remove Client reference
mutable.Publish: stop passing Client
mutable.ServermapUpdater: get StorageBroker in constructor, not by peeking into Client reference
MutableChecker: reference StorageBroker and History directly, not through Client
mutable.FileNode: removed unused indirection to checker classes
mutable.FileNode: remove Client reference
client.py: move RSA key generation into a separate class, so it can be passed to the nodemaker
move create_mutable_file() into NodeMaker
test_dirnode.py: stop using FakeClient mockups, use NoNetworkGrid instead. This simplifies the code, but takes longer to run (17s instead of 6s). This should come down later when other cleanups make it possible to use simpler (non-RSA) fake mutable files for dirnode tests.
test_mutable.py: clean up basedir names
client.py: move create_empty_dirnode() into NodeMaker
dirnode.py: get rid of DirectoryNode.create
remove DirectoryNode.init_from_uri, refactor NodeMaker for customization, simplify test_web's mock Client to match
stop passing Client to DirectoryNode, make DirectoryNode.create_with_mutablefile the normal DirectoryNode constructor, start removing client from NodeMaker
remove Client from NodeMaker
move helper status into History, pass History to web.Status instead of Client
test_mutable.py: fix minor typo
