oops. I screwed up the makefile syntax further. buildslave would spend a
lot of fruitless time trawling the entire drive. this fixes that. and a
stray -n. ahem. [looks down sheepishly]
blah $( foo ) is more explicit than blah ` foo ` in a bash-like context
unfortunately it doesn't translate very well to makefiles, for which $(
means something else entirely
rather than trying to build a single .app with both 10.4 and 10.5 fuse
libraries embedded within it, for the time being, we're just going to
have independant 10.4 and 10.5 builds.
this provides a 10.5 _fusemodule.so, and build changes to copy the
appropriate versions of files for 10.4 or 10.5 from sub dirs of mac/
into the build tree before triggering py2app
the existing environment on otto requires a few build hints in order for
xml parsing to work properly. these hints are unnecessary, and moreover
their import by depends.py is broken, in the 10.5 environment in which
zandr's buildslave is running.
the make mac-upload target now requires an UPLOAD_DEST argument to be given,
which is the rsync destination (including trailing '/') to which the version
stamped directory containing the .dmg should be placed. the account the
build is running as (e.g. 'buildslave') should have ssh access to the account
specified in that dest. one might also consider locking the key down to the
target directory by adding something like
command="rsync --server -vlogDtpr . /home/amduser/public_html/dist/mac-blah/"
to the corresponding authorized_key entry on the target machine.
the mac/macfuse subdirectory needed to be added to the pythonpath in order
to build a binary incorporating the mac fuse system. this change should
make those modules accessible relative to the mac/ directory which is
implicitly included in the .app build process.
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.
This is the result of various experimentation done into using python-fuse
to provide access to tahoe on the mac. It's rough in quite a few places,
and is really the result of investigation more than a thorough
implemenation of the fuse api.
upon launch, it looks for the users root_dir by opening ~/.tahoe/node.url
and ~/.tahoe/private/root_dir.cap it then proceeds to cache the directory
structure found by walking the users tahoe drive (safely in the face of
directory loops) into memory and then mounts that filesystem.
when a file is read, it calls the tahoe node to first download the file
into a cache directory (~/.tahoe/_cache) and then serves up the file
from there.
when a file is written, a temporary file is allocated within the tmp dir
of the cache, and upon close() (specifically upon release()) the file is
uploaded to the tahoe node, and the new directory entry written.
note that while the durectory structure is cached into memory only when
the filesystem is mounted, that it is 'write through' i.e. changes made
via fuse are reflected into the underlying tahoe fs, even though changes
made to the tahoe fs otherwise show up only upon restart.
in addition to opening files for read and write, the mkdir() and rename()
calls are supported. most other file system operations are not yet
supported. notably stat() metadata is not currently tracked by tahoe,
and is variably reported by this fs depending on write cache files.
also note that this version does not fully support Finder. access through
normal unix commands such as cat, cp, mv, ls etc works fine, and read
access to file from within finder (including preview images and double-
click to open) work ok. but copies to the tahoe drive from within finder
may or may not succeed, but will always report an error. This is still
under investigation.
also note that this does not include any build integration. the included
_fusemodule.so was built on mac os 10.4 against macfuse 1.3.0, and is
known to not work against 10.5-1.3.1 it's possible it may also contain
dependencies upon parts of macports used to build the python that it was
built against. this will be cleaned up later.
usage:
python tahoefuse.py /Path/to/choice/of/mountpoint
or optionally
python tahoefuse.py -ovolicon=/Path/to/icon.icns /Path/to/mountpoint
upon startup, tahoefuse will walk the tahoe directory, then print a
summary of files and folders found, and then daemonise itself. to exit,
either eject the 'drive' (note: 10.5 doesn't show it as a drive, since
it considers fuse to be a connected server instead) or unmount it via
umount /Path/to/mountpoint etc.
this moves some of the code common to both windows and mac builds into the
allmydata module hierarchy, and cleans up the windows and mac build directories
to import the code from there.
remove debug messages (and traceback) from node output in the case that the
pkg resources hook can't find a requested file. it will now silently return
the empty string for files that can't be resolved
refine the logic in the .app which tries to install the 'tahoe' script.
now it will do nothing if 'tahoe' is found anywhere on the user's path,
and only if it's not present will it try to install it in each of the
candidate paths (/usr/local/bin ~/bin ~/Library/bin) which are on the
user's path
upon startup, the .app will look in '/usr/local/bin', '~/bin', '~/Library/bin'
if it finds one of these dirs, and can write into it, and there isn't already
a 'tahoe' present, it will write a small bach script which will launch the
binary contained within the .app bundle
this allows the .app bundle to offer the services of the 'tahoe' script
easily and simply
This patch adds support for a mac native build.
At the moment it's a fairly simple .app - i.e. so simple as to be unacceptable
for a shipping product, but ok for testing and experiment at this point.
notably once launched, the app's ui does not respond at all, although its dock
icon does allow it to be force-quit.
this produces a single .app bundle, which when run will look for a node basedir
in ~/.tahoe. If one is not found, one will be created in ~/Library/Application
Support/Allmydata Tahoe, and that will be symlinked to ~/.tahoe
if the basedir is lacking basic config (introducer.furl and root_dir.cap) then
the wx config wizard will be launched to log into an account and to set up
those files.
if a webport file is not found, the default value of 8123 will be written into
it.
once the node has started running, a webbrowser will be opened to the webish
interface at the users root_dir
note that, once configured, the node runs as the main thread of the .app,
no daemonisation is done, twistd is not involved.
the binary itself, from within the .app bundle, i.e.
"Allmydata Tahoe.app/Contents/MacOS/Allmydata Tahoe"
can be used from the command line and functions as the 'tahoe' executable
would in a unix environment, with one exception - when launched with no args
it triggers the default behaviour of running a node, and if necessary config
wizard, as if the user had launched the .app
one other gotcha to be aware of is that symlinking to this binary from some
other place in ones $PATH will most likely not work. when I tried this,
something - wx I believe - exploded, since it seems to use argv[0] to figure
out where necessary libraries reside and fails if argv[0] isn't in the .app
bundle. it's pretty easy to set up a script a la
#!/bin/bash
/Blah/blah/blah/Allmydata\ Tahoe.app/Contents/MacOS/Allmydata\ Tahoe "${@}"
