Apparently none of the two authors (stercor, terrell), three reviewers (warner, davidsarah, terrell), or one committer (me) actually ran the tests. This is presumably due to #20.
fixes#1412
Pass around IServer instance instead of (peerid, rref) tuple. Replace
"descriptor" with "server". Other replacements:
get_all_servers -> get_connected_servers/get_known_servers
get_servers_for_index -> get_servers_for_psi (now returns IServers)
This change still needs to be pushed further down: lots of code is now
getting the IServer and then distributing (peerid, rref) internally.
Instead, it ought to distribute the IServer internally and delay
extracting a serverid or rref until the last moment.
no_network.py was updated to retain parallelism.
This patch also renames some instances of "find_shares()" to "find_all_shares()" and other instances to "find_uri_shares()" as appropriate -- the conflation between those names confused me at first when writing these tests.
Stop checking separately for ConnectionDone/ConnectionLost, since those have
been folded into DeadReferenceError since foolscap-0.3.1 . Write
rrefutil.trap_deadref() in terms of rrefutil.trap_and_discard() to improve
code coverage.
* remove Downloader.download_to_data/download_to_filename/download_to_filehandle
* remove download.Data/FileName/FileHandle targets
* remove filenode.download/download_to_data/download_to_filename methods
* leave Downloader.download (the whole Downloader will go away eventually)
* add util.consumer.MemoryConsumer/download_to_data, for convenience
(this is mostly used by unit tests, but it gets used by enough non-test
code to warrant putting it in allmydata.util)
* update tests
* removes about 180 lines of code. Yay negative code days!
Overall plan is to rewrite immutable/download.py and leave filenode.read() as
the sole read-side API.
* change t=mkdir-with-children to not use multipart/form encoding. Instead,
the request body is all JSON. t=mkdir-immutable uses this format too.
* make nodemaker.create_immutable_dirnode() get convergence from SecretHolder,
but let callers override it
* raise NotDeepImmutableError instead of using assert()
* add mutable= argument to DirectoryNode.create_subdirectory(), default True
* "cap" means a python instance which encapsulates a filecap/dircap (uri.py)
* "uri" means a string with a "URI:" prefix
* FileNode instances are created with (and retain) a cap instance, and
generate uri strings on demand
* .get_cap/get_readcap/get_verifycap/get_repaircap return cap instances
* .get_uri/get_readonly_uri return uri strings
* add filenode.download_to_filename() for control.py, should find a better way
* use MutableFileNode.init_from_cap, not .init_from_uri
* directory URI instances: use get_filenode_cap, not get_filenode_uri
* update/cleanup bench_dirnode.py to match, add Makefile target to run it
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
This reduces the total test time on my laptop from 400s to 283s.
* src/allmydata/test/test_system.py (SystemTest.test_mutable._test_debug):
Remove assertion about container_size/data_size, this changes with keysize
and was too variable anyways.
* src/allmydata/mutable/filenode.py (MutableFileNode.create): add keysize=
* src/allmydata/dirnode.py (NewDirectoryNode.create): same
* src/allmydata/client.py (Client.DEFAULT_MUTABLE_KEYSIZE): add default,
this overrides the one in MutableFileNode
