1. changed the node's exit-on-error behaviour. rather than logging debug and
then delegating to self for _abort_process() instead simply delegate to self
_service_startup_failed(failure) to report failures in the startup deferred
chain. subclasses then have complete control of handling and reporting any
failures in node startup.
2. replace the convoluted wx.PostEvent() glue for posting an event into the
gui thread with the simpler expedient of wx.CallAfter() which is much like
foolscap's eventually() but also thread safe for inducing a call back on the
gui thread.
in certain cases (e.g. the node.pem changed but old .furls are in private/)
the node will abort upon startup. previously it used os.abort() which in these
cases caused the mac gui app to crash on startup with no explanation.
this changes that behaviour from calling os.abort() to calling
node._abort_process(failure) which by default calls os.abort(). this allows
that method to be overridden in subclasses.
the mac app now provides and uses such a subclass of Client, so that failures
are reported to the user in a message dialog before the process exits.
this uses wx.PostEvent() with a custom event type to signal from the reactor
thread into the gui thread.
the confwiz now uses socket.gethostname() if a 'nickname' file doesn't already
exist, and passes that nickname into the 'record_install' method on the backend,
so that the moniker can be recorded in the system table.
when an operation takes 'too long', on 10.4 the user gets a dialog about
the problem with a 'force eject / keep trying' choice. on 10.5 the fuse
system seems to summarily unmount the drive.
this showed up in 10.5 testing because the time to open() a file depended
upon the size of the file, and an 8Mb test file took long enough for the
node to download that the open() call didn't respond within 60s and fuse
spontaneously ejected the drive, quitting the plugin (and cancelling the
download).
this changes the fuse options passed to the plugin by the ui when the
'mount filesystem' window is used. command line users should check out
the '-odaemon_timeout=...' option. this changes the default timeout from
60s to 300s (5min) for ui launched plugins.
this will be addressed in a deeper manner at a later date, with a more
advanced fuse subsystem which can interleave open()/read() with the
actual download of the file, only blocking when data is not downloaded
yet.
Unfinished bits: doc in webapi.txt, test handling of badly formed JSON, return reasonable HTTP response, examination of the effect of this patch on code coverage -- but I'm committing it anyway because MikeB can use it and I'm being called to dinner...
the name 'tahoe' is in the process of being removed from the windows
installer and binaries. this changes the name of the smb service the
confwiz tries to start to 'Allmydata SMB'
this adds an action to the dock menu and to the file menu (when visible)
"Mount Filesystem". This action opens a windows offering the user an
opportunity to select from any of the named *.cap files in their
.tahoe/private directory, and choose a corresponding mount point to mount
that at.
it launches the .app binary as a subprocess with the corresponding command
line arguments to launch the 'tahoe fuse' functionality to mount that file
system. if a NAME.icns file is present in .tahoe/private alonside the
chosen NAME.cap, then that icon will be used when the filesystem is mounted.
this is highly unlikely to work when running from source, since it uses
introspection on sys.executable to find the relavent binary to launch in
order to get the right built .app's 'tahoe fuse' functionality.
it is also relatively likely that the code currently checked in, hence
linked into the build, will have as yet unresolved library dependencies.
it's quite unlikely to work on 10.5 with macfuse 1.3.1 at the moment.
this provides a variety of changes to the macfuse 'tahoefuse' implementation.
most notably it extends the 'tahoe' command available through the mac build
to provide a 'fuse' subcommand, which invokes tahoefuse. this addresses
various aspects of main(argv) handling, sys.argv manipulation to provide an
appropriate command line syntax that meshes with the fuse library's built-
in command line parsing.
this provides a "tahoe fuse [dir_cap_name] [fuse_options] mountpoint"
command, where dir_cap_name is an optional name of a .cap file to be found
in ~/.tahoe/private defaulting to the standard root_dir.cap. fuse_options
if given are passed into the fuse system as its normal command line options
and the mountpoint is checked for existence before launching fuse.
the tahoe 'fuse' command is provided as an additional_command to the tahoe
runner in the case that it's launched from the mac .app binary.
this also includes a tweak to the TFS class which incorporates the ctime
and mtime of files into the tahoe fs model, if available.
runner provides the main point of entry for the 'tahoe' command, and
provides various subcommands by default. this provides a hook whereby
additional subcommands can be added in in other contexts, providing a
simple way to extend the (sub)commands space available through 'tahoe'
regardless of platform, the confwiz now opens the welcoe page upon
writing a config. it also provides a 'plat' argument (from python's
sys.platform) to help disambiguate our instructions by platform.
adds command line option parsing to the confwiz.
the previous --uninstall option behaves as before, but it parsed
more explicitly with the twisted usage library.
added is a --server option, which controls which web site the
backend script for configuration is to be found on. (it is looked
for at /native_client.php on the given server) this option can be
used on conjunction with --uninstall to control where the uninstall
is recorded
Options:
-u, --uninstall record uninstall
-s, --server= url of server to contact
[default: https://beta.allmydata.com/]
e.g. confwiz.py -s https://www-test.allmydata.com/
while investigating fuse related stuff, I spent quite a while staring at
very cryptic explosions I got from idlib. it turns out that unicode
objects and str objects have .translate() methods with differing signatures.
to save anyone else the headache, this makes it very clear if you accidentally
try to pass a unicode object in to a2b() etc.
base62 encoding fits more information into alphanumeric chars while avoiding the troublesome non-alphanumeric chars of base64 encoding. In particular, this allows us to work around the ext3 "32,000 entries in a directory" limit while retaining the convenient property that the intermediate directory names are leading prefixes of the storage index file names.
