The old copy had a bug which occasionally returns a port that was
actually in use, causing intermittent test failures (when large numbers
of ports were allocated). I finally figured out how to fix it in
Foolscap, so this is just a copy of the updated function.
closes ticket:2795
The udpprot.transport.connect() fails if we don't have a network
connection, but the port is still listening, so trial gives us a
DirtyReactorError. The fix is a "finally:" which does
port.stopListening() even in this case.
Closes ticket:2769
As discussed at https://tahoe-lafs.org/trac/tahoe-lafs/ticket/1973 and in
previous pull request #129.
- replace lengthy timestamps with human-readable deltas (eg 1h 2m 3s)
- replace "announced" column with "Last RX" column
- remove service column (it always said the same thing, "storage")
- fix colspan on 'You are not presently connected' message
Previous versions, some with github comments: 3fe9053134 , 486dbfc7bd , and c89ea62580, 9fabb92486, bbd8b42a25
Unlike previous attempts, the tests on this one should pass in any timezone.
(But like current master, will fail with Nevow >=0.12...)
Thanks to an anonymous contributor who wrote some of the tests.

A long time ago, the introducer's status web page would show the
advertised IP addresses for all published services, by parsing their
FURL's connection hints. This hasn't worked since about 12-Aug-2014 when
foolscap-0.6.5 changed the internal format of these hints (the column
has been empty this whole time).
This removes the "Advertised IPs" column from the Service Announcements
table. Instead, the service's full connection hints (not just the IP
address) is displayed in a tooltip/popup on the "Announced" timestamp
column.
The code that pulls these connection hints is now tolerant of all three
foolscap styles:
* foolscap<=0.6.4 : tuples of ("ipv4",host,port)
* 0.6.5 .. 0.8.0 : tuples of ("tcp",host,port)
* foolscap>=0.9.0 : strings
fixes ticket:2510
A long time ago, the introducer's status web page would show the
advertised IP addresses for all subscribers, by parsing their
RemoteReference's FURL's connection hints. This hasn't worked since
about 12-Aug-2014 when foolscap-0.6.5 changed the internal format of
these hints.
This removes the feature: we no longer attempt to show advertised IP
addresses of subscribed clients. It also removes the code that looked
inside foolscap internals for this information.
The stdlib 'subprocess' module in python-2.7.4 through 2.7.7 suffers
from http://bugs.python.org/issue18851 which causes unrelated file
descriptors to be closed when `subprocess.call()` fails the `exec()`,
such as when the executable being invoked does not actually exist. There
appears to be some randomness involved. This was fixed in python-2.7.8.
Tahoe's iputil.py uses subprocess.call on many different "ifconfig"-type
executables, most of which don't exist on any given platform (added in
git commit 8e31d66cd0). This results in a lot of file-descriptor
closing, which (at least during unit tests) tends to clobber important
things like Tub TCP sockets. This seems to be the root cause behind
ticket:2121, in which normal code tries to close already-closed sockets,
crashing the unit tests. Since different platforms have different
ifconfigs, some platforms will experience more failed execs than others,
so this bug could easily behave differently on linux vs freebsd, as well
as working normally on python-2.7.8 or 2.7.4.
This patch inserts a guard to make sure that os.path.isfile() is true
before allowing Popen.call() to try executing the target. This ought to
be enough to avoid the bug. It changes both iputil.py and
allmydata.__init__ (which uses Popen for calling "lsb_release"), which
are all the places where 'subprocess' is used outside of unit tests.
Other potential fixes: use the 'subprocess32' module from PyPI (which is
a bug-free backport of the Python3 stdlib subprocess module, but would
introduce a new dependency), or require python >= 2.7.8 (but this would
rule out development/deployment on the current OS-X 10.9 release, which
ships with 2.7.5, as well as other distributions like Ubuntu 14.04 LTS).
I believe this closes ticket:2121, and given the apparent relationship
between 2121 and 2023, I think it also closes ticket:2023 (although
since 2023 doesn't have copies of the failing log files, it's hard to
tell). I'm hoping that this will tide us over until 1.11 is released, at
which point we can execute on the plan to remove iputil.py entirely by
changing the way that nodes learn their externally-facing IP address.
