zooko recently added a runtime check, via setuptools, that specific versions of various
packages were reported as available through setuptools at runtime.
however exe and app builds run with collected egg contents, not linked against entire
eggs, i.e. the code is transcluded into a single library.zip
thus setuptools reports that those specific version cannot be reported as available,
though they are in fact available built into the library
this disables that runtime check if the app is running 'frozen'
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 $PATH will most likely not work. when I tried this,
something - wx I believe - exploded, since it seems to use argv[0] to figure
out where necessary libraries reside and fails if argv[0] isn't in the .app
bundle. it's pretty easy to set up a script a la
#!/bin/bash
/Blah/blah/blah/Allmydata\ Tahoe.app/Contents/MacOS/Allmydata\ Tahoe "${@}"
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.
this changes the confwiz so that hitting the 'create account' button, rather than
opening a webbrowser to the register page, instead provides a simple account creation
ui directly, along with changes to the backend (native_client.php) to support that.
also added a 'connecting...' message so the user sees a response when they hit
login or create account, since the getBasedir call can sometimes take up to ~5min
(which is unacceptable for a user product, but this at least somewhat ameliorates
the issue of the ui locking up and not giving the user any feedback while it's
happening)
Now we use "./setup.py develop" to ensure that changes to our source code are immediately used without requiring a "make" step. This simplification will hopefully pave the way for easier py2exe and py2app, solving the "Unit tests test the installed version" bug (#145), and perhaps also #164 and #176.
This patch also conditionalizes the use of setuptools_darcs on the absence of a PKG-INFO file, which is part of fixing #263.
I chose to remove mention of non-convergent encoding, not because I dislike non-convergent encoding, but because that option isn't currently expressed in the API and in order to shorten architecture.txt. I renamed "URI" to "Capability". I did some editing, including updating a few places that treated all capabilities as CHK-capabilities and that mentioned that distributed SSKs were not yet implemented.
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.
this closes the reader before trying to unlink the encoding file within the
CHKUploadHelper.
since the installer upload got more complex (needing to chmod files before
rsyncing) I promoted it to a makefile target, simplifying the buildbot steps
involved
this adds the latest build of mike's winfuse plugins, now also running as
a windows service (and using the node.url, private/root_dir.cap files from
the noderoot specified by the registry) into the install process.
