Meejah pointed out that new users might think the encoding parameters
are fixed, something you must pick correctly when you first set up the
node, and then are never allowed to change again, which is kind of
anxiety-inducing. This updates the comment to explain that the encoding
is stored in each filecap, and the tahoe.cfg values are only used for
newly-uploaded files.
Also:
* do some light refactoring of create-client/node
* make it clear that these commands' --basedir options do the same as
the global --node-directory option
* use "global-options" instead of "global-opts"
The new rules for "bin/tahoe ARG1.. SUBCOMMAND ARG2.." arg:
* --node-directory is only accepted in ARG1, not ARG2
* create-*/start/stop/restart accept --basedir in ARG2, or an explicit
basedir argument
* only one of --node-directory/--basedir/explicit-basedir is accepted
* --quiet/--version is only accepted in ARG1, not ARG2
Closes#166
I rerecorded this patch, originally by David-Sarah, to use "darcs replace" instead of editing to do the renames. This uncovered one missed rename in Client.init_drop_uploader. (Which also means that code isn't exercised by the current unit tests.)
refs #1429
I personally used "tahoe start/restart -m ../MY-TESTNET/node*" all the time,
to spin up or update a local testgrid while iterating over new code. However,
with the recent switch from "subprocess.Popen(/bin/twistd)" to "import and
call twistd.run()" in scripts/startstop_node.py (yay fewer processes!),
"start -m" broke, and fixing it requires os.fork, which is unavailable on
windows (boo windows!). And I was probably the only one using -m. So in the
interests of uniformity among platforms and simpler code (yay negative code
days!), we're just removing -m from everything. I will start using a little
shell script or something to simulate the removed functionality.
This patch also cleans up CLI-function calling a bit: get the basedir from
the config dict (instead of sometimes from a separate argument), and always
return a numeric exit code.
* rename my_private_dir.cap to root_dir.cap
* move it into the private subdir
* change the cmdline argument "--root-uri=[private]" to "--dir-uri=[root]"
* use new decentralized directories everywhere instead of old centralized directories
* provide UI to them through the web server
* provide UI to them through the CLI
* update unit tests to simulate decentralized mutable directories in order to test other components that rely on them
* remove the notion of a "vdrive server" and a client thereof
* remove the notion of a "public vdrive", which was a directory that was centrally published/subscribed automatically by the tahoe node (you can accomplish this manually by making a directory and posting the URL to it on your web site, for example)
* add a notion of "wait_for_numpeers" when you need to publish data to peers, which is how many peers should be attached before you start. The default is 1.
* add __repr__ for filesystem nodes (note: these reprs contain a few bits of the secret key!)
* fix a few bugs where we used to equate "mutable" with "not read-only". Nowadays all directories are mutable, but some might be read-only (to you).
* fix a few bugs where code wasn't aware of the new general-purpose metadata dict the comes with each filesystem edge
* sundry fixes to unit tests to adjust to the new directories, e.g. don't assume that every share on disk belongs to a chk file.
