fuse/blackmatch: split into client/server (twisted server)
This implements a client/server split for blackmatch, where the client
implements the fuse_main bindings and a simple blocking rpc client mechanism.
The server implements the other half of that rpc mechanism, and contains all
the actual logic for interpreting fuse requests in the context of the on disk
cache and requests to the tahoe node. The server is based on a twisted reactor.
The rpc mechanism implements a simple method dispatch including marshalling,
using json, of basic inert data types, in a flat namespace (no objects).
The client side is written in a blocking idiom, to interface with the threading
model used by the fuse_main bindings, whereas the server side is written for a
twisted reactor-based environment, intended to facilitate implementing more
sophisticated logic in that paradigm. The two communicate over a unix domain
socket, allocated within the nodedir.
Command line usage is unchanged; the server is launched automatically by the
client. The server daemonizes itself, to avoid preventing the original parent
process (e.g. 'runtests') from waiting upon the server exiting.
The client keeps open a 'keepalive' connection to the server; upon loss thereof
the server will exit. This addresses the fact that the python-fuse bindings
provide no notification of exit of the client process upon unmount.
The client thus provides a relatively thin 'shim' proxying requests from the
fuse_main bindings across the rpc to the server process, which handles the
logic behind each request.
For the time being, a '--no-split' option is provided to surpress the splitting
into client/server, yielding the prior behaviour. Once the server logic gets
more complex and more entrenched in a twisted idiom, this might be removed.
The 'runtests' test harness currently tests both modes, as 'impl_c' and
'impl_c_no_split'

gui/macapp: rough cut of ui tweaks; configurability, auto-mount
chatting with peter, two things the mac gui needed were the ability to mount
the 'allmydata drive' automatically upon launching the app, and open the
Finder to reveal it. (also a request to hide the debug 'open webroot' stuff)
this (somewhat rough) patch implements all the above as default behaviour
it also contains a quick configuration mechanism for the gui - rather than a
preferences gui, running with a more 'tahoe' styled mechanism, the contents
of a few optional files can modify the default behaviour, specifically file
in ~/.tahoe/gui.conf control behaviour as follows:
auto-mount (bool): if set (the default) then the mac app will, upon launch
automatically mount the 'tahoe:' alias with the display name 'Allmydata'
using a mountpoint of ~/.tahoe/mnt/__auto__
auto-open (bool): if set (the default) then upon mounting a file system
(including the auto-mount if set) finder will be opened to the mountpoint
of the filesystem, which essentially reveals the newly mounted drive in a
Finder window
show-webopen (bool): if set (false by default) then the 'open webroot'
action will be made available in both the dock and file menus of the app
daemon-timout (int): sets the daemon-timeout option passed into tahoe fuse
when a filesystem is mounted. this defaults to 5 min
files of type (int) much, naturally contain a parsable int representation.
files of type (bool) are considered true if their (case-insensitive) contents
are any of ['y', 'yes', 'true', 'on', '1'] and considered false otherwise.

fuse/impl_c: UNDO --auto-fsid option
rolling back:
Thu Sep 25 14:42:23 BST 2008 robk-tahoe@allmydata.com
* fuse/impl_c: add --auto-fsid option
this was inspired by reading the fuse docs and discovering the 'fsid' option
to fuse_main, and was _intended_ to support a sort of 'stability' to the
filesystem (specifically derived from the root-uri mounted, whether directly
or via an alias) to support mac aliases across unmount/remount etc.
some experimentation shows that that doesn't actually work, and that, at
least for mac aliases in my testing, they're tied to path-to-mountpoint and
not to the fsid - which seems to have no bearing. perhaps the 'local' flag
is causing weirdness therein.
at any rate, I'm recording it simply for posterity, in case it turns out to
be useful after all somewhere down the road.
