This patch modifies the regular expression used for verifying of '--node-url'
parameter. Support for accessing a Tahoe gateway over HTTPS was already
present, thanks to Python's urllib.
This handles the case where we upload a new tahoe directory for a
previously-processed local directory, possibly creating a new dircap (if the
metadata had changed). Now we replace the old dirhash->dircap record. The
previous behavior left the old record in place (with the old dircap and
timestamps), so we'd never stop creating new directories and never converge
on a null backup.
It is not called "installing" because that implies that it is going to change the configuration of your operating system. It is not called "building" because that implies that you need developer tools like a compiler. Also I added a stern warning against looking at the "InstallDetails" wiki page, which I have renamed to "AdvancedInstall".
These edits were suggested by my watching over Jake Appelbaum's shoulder as he completely ignored/skipped/missed install.html and also as he decided that debian.txt wouldn't help him with basic installation. Then I threw in a few docs edits that have been sitting around in my sandbox asking to be committed for months.
To test the changes for #577, we need a deterministic way to simulate
the passage of long periods of time. twisted.internet.task.Clock seems,
from my Googling, to be the way to go for this functionality. I changed
a few things so that OphandleTable would use twisted.internet.task.Clock
when testing:
* WebishServer.__init___ now takes an optional 'clock' parameter,
* which it passes to the root.Root instance it creates.
* root.Root.__init__ now takes an optional 'clock' parameter, which it
passes to the OphandleTable.__init__ method.
* OphandleTable.__init__ now takes an optional 'clock' parameter. If
it is provided, and it isn't None, its callLater method will be used
to schedule ophandle expirations (as opposed to using
reactor.callLater, which is what OphandleTable does normally).
* The WebMixin object in test_web.py now sets a self.clock parameter,
which is a twisted.internet.task.Clock that it feeds to the
WebishServer it creates.
Tests using the WebMixin can control the passage of time in
OphandleTable by accessing self.clock.
