from testing on linux (specifically ubuntu hardy) the libfuse dll has a
different name, specifically libfuse.so.2. this patch tries libfuse.so
and then falls back to trying .2 if the former fails.
it also changes the unmount behaviour, to simply return from the handler's
loop_forever() loop upon being unmounted, rather than raising an EOFError,
since none of the client code I looked at actually handled that exception,
but did seem to expect to fall off of main() when loop_forever() returned.
Additionally, from my testing unmount typically led to an OSError from the
fuse fd read, rather than an empty read, as the code seemed to expect.
also removed a spurious import pyflakes quibbled about.
zooko helped me unravel a build weirdness today. somehow the system installed
twisted (/System/Library) was pulling in parts of the other twisted (/Library)
which had been installed by easy_install, and exploding.
getting rid of the latter helped, but it took this change to get the tahoe
build to stop trying to rebuild twisted and instead use the one that was
already installed. c.f. tkt #229
in the recent reconciliation of webopen patches, I wound up adjusting
webopen to 'pass through' the state of the trailing slash on the given
argument to the resultant url passed to the browser. this change
removes the requirement that arguments must be directories, and allows
webopen to be used with files. it also broke the tests that assumed
that webopen would always normalise the url to have a trailing slash.
in fixing the tests, I realised that, IMHO, there's something deeply
awry with the way tahoe handles paths; specifically in the combination
of '/' being the name of the root path within an alias, but a leading
slash on paths, e.g. 'alias:/path', is catagorically incorrect. i.e.
'tahoe:' == 'tahoe:/' == '/'
but 'tahoe:/foo' is an invalid path, and must be 'tahoe:foo'
I wound up making the internals of webopen simply spot a 'path' of
'/' and smash it to '', which 'fixes' webopen to match the behaviour
of tahoe's path handling elsewhere, but that special case sort of
points to the weirdness.
(fwiw, I personally found the fact that the leading / in a path was
disallowed to be weird - I'm just used to seeing paths qualified by
the leading / I guess - so in a debate about normalising path handling
I'd vote to include the /)
I think this is largely attributable to a cleanup patch I'd made
which never got committed upstream somehow, but at any rate various
conflicting changes to webopen had been made. This cleans up the
conflicts therein, and hopefully brings 'tahoe webopen' in line with
other cli commands.
moved the body of webopen out of cli.py into tahoe_webopen.py
made its invocation consistent with the other cli commands, most
notably replacing its 'vdrive path' with the same alias parsing,
allowing usage such as 'tahoe webopen private:Pictures/xti'
This should make it sufficiently fast, while still giving a better answer on Ubuntu than platform.dist() currently does, and also falling back to lsb_release if platform.dist() says that it doesn't know.
* the two kinds of immutable filenode now have a common base class
* they store only an instance of their URI, not both an instance and a string
* they delegate comparison to that instance
