* fix CLI commands (put, mkdir) to send format=, not mutable-type=
* fix tests
* test_cli: fix tests that observe t=json output, don't ignore failures in
'tahoe put'
* fix handling of version= to make it easier to use the default
* interpret ?mutable=true&format=MDMF as MDMF, not SDMF
- Learn how to create MDMF files and directories through the
mutable-type argument.
- Operate with the interface changes associated with MDMF and #993.
- Learn how to do partial updates of mutable files.
This forbids operations that would implicitly create a directory with a
zero-length (empty string) name, like what you'd get if you did "tahoe put
local /oops/blah" (#358) or "POST /uri/CAP//?t=mkdir" (#676). The error
message is fairly friendly too.
Also added code to "tahoe put" to catch this error beforehand and suggest the
correct syntax (i.e. without the leading slash).
* 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
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.
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
webapi.txt: clarify replace=only-files argument, mention replace= on POST t=uri
test_cli.py: insert whitespace between logical operations
web.common.parse_replace_arg: make it case-insensitive, to match the docs
This walks slowly through all shares, examining their leases, deciding which
are still valid and which have expired. Once enabled, it will then remove the
expired leases, and delete shares which no longer have any valid leases. Note
that there is not yet a tahoe.cfg option to enable lease-deletion: the
current code is read-only. A subsequent patch will add a tahoe.cfg knob to
control this, as well as docs. Some other minor items included in this patch:
tahoe debug dump-share has a new --leases-only flag
storage sharefile/leaseinfo code is cleaned up
storage web status page (/storage) has more info, more tests coverage
space-left measurement on OS-X should be more accurate (it was off by 2048x)
(use stat .f_frsize instead of f_bsize)
