this will write an arbitrary number of config files, instead of being restricted
to just the introducer.furl, based on the response of the php backend.
the get_config is passed username/password
Previously, once the node itself was launched, the UI event loop was no longer
running. This meant that the app would sit around seemingly 'wedged' and being
reported as 'Not Responding' by the os.
This chnages that by actually implementing a wxPython gui which is left running
while the reactor, and the node within it, is launched in another thread.
Beyond 'quit' -> reactor.stop, there are no interactions between the threads.
The ui provides 'open web root' and 'open account page' actions, both in the
file menu, and in the (right click) dock icon menu.
Something weird in the handling of wxpython's per-frame menubar stuff seems to
mean that the menu bar only displays the file menu and about etc (i.e. the items
from the wx menubar) if the focus changes from and back to the app while the
frame the menubar belongs to is displayed. Hence a splash frame comes up at
startup to provide an opportunity.
It also seems that, in the case that the file menu is not available, that one
can induce it to reappear by choosing 'about' from the dock menu, and then
closing the about window.
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.
using sibpath to find web template files relative to source code is functional
when running from source environments, but not especially flexible when running
from bundled built environments. the more 'orthodox' mechanism, pkg_resources,
in theory at least, knows how to find resource files in various environments.
this makes the 'web' directory in allmydata into an actual allmydata.web module
(since pkg_resources looks for files relative to a named module, and that module
must be importable) and uses pkg_resources.resource_filename to find the files
therein.
Using pkg_resources.require() like this also apparently allows people to install multiple different versions of packages on their system and tahoe (if pkg_resources is available to it) will import the version of the package that it requires. I haven't tested this feature.
in a discussion the other day, brian had asked me to try removing this fix, since
it leads to double-closing the reader. since on my windows box, the test failures
I'd experienced were related to the ConnectionLost exception problem, and this
close didn't see to make a difference to test results, I agreed.
turns out that the buildbot's environment does fail without this fix, even with
the exception fix, as I'd kind of expected.
it makes sense, because the reader (specifically the file handle) must be closed
before it can be unlinked. at any rate, I'm reinstating this, in order to fix the
windows build
unlinking a file before closing it is not portable. it works on unix, but fails
since an open file holds a lock on windows.
this closes the reader before trying to unlink the encoding file within the
CHKUploadHelper.
in trying to test my fix for the failure of the offloaded unit test on windows
(by closing the reader before unlinking the encoding file - which, perhaps
disturbingly doesn't actually make a difference in my windows environment)
I was unable too because the unit test failed every time with a connection lost
error.
after much more time than I'd like to admit it took, I eventually managed to
track that down to a part of the unit test which is supposed to be be dropping
a connection. it looks like the exceptions that get thrown on unix, or at
least all the specific environments brian tested in, for that dropped
connection are different from what is thrown on my box (which is running py2.4
and twisted 2.4.0, for reference) adding ConnectionLost to the list of
expected exceptions makes the test pass.
though curiously still my test logs a NotEnoughWritersError error, and I'm not
currently able to fathom why that exception isn't leading to any overall
failure of the unit test itself.
for general interest, a large part of the time spent trying to track this down
was lost to the state of logging. I added a whole bunch of logging to try
and track down where the tests were failing, but then spent a bunch of time
searching in vain for that log output. as far as I can tell at this point
the unit tests are themselves logging to foolscap's log module, but that isn't
being directed anywhere, so all the test's logging is being black holed.
unlinking a file before closing it is not portable. it works on unix, but fails
since an open file holds a lock on windows.

use of twisted.python.util.sibpath to find files relative to modules doesn't
work when those modules are bundled into a library by py2exe. this provides
an alternative implementation (in allmydata.util.sibpath) which checks for
the existence of the file, and if it is not found, attempts to find it relative
to sys.executable instead.
adds a 'run' commands to bin/tahoe / tahoe.exe
it loads a client node into the tahoe process itself,
running in the base dir specified by --basedir/-C and
defaulting to the current working dir.
it runs synchronously, and the tahoe process blocks until
the reactor is stopped.
this is probably not of very high utility in the unix case of bin/tahoe
but is useful when working with native builds, e.g. py2exe's tahoe.exe,
to examine and debug the runtime environment, linking problems etc.
a recent purge of the start.html code also took away the logic that wrote
'node.url' into the node root. this is required for the tahoe cli tool to
find the node. this puts back a limited fraction of that code, so that the
node writes out a node.url file upon startup.
taking the same arguments as tahoe ls, it does a webbrowser.open to the page
specified by those args. hence "tahoe webopen" will open a browser to the
root dir specified in private/root_dir.cap by default.
this might be a good alternative to the start.html page.
* 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]"
Unfortunately although it passes the unit tests, it doesn't work, because the unit tests and the implementation use the "encode params into URL" technique but the button uses the "encode params into request body" technique.
Also allow an optional leading "http://127.0.0.1:8123/uri/".
Also fix a few unit tests to generate bogus Dirnode URIs of the modern form instead of the former form.
