With the new Foolscap-0.11.0 (which changed the way connections are
established), I'm seeing DirtyReactorErrors getting thrown by
allmydata.test.test_system.SystemTest.test_filesystem_with_cli_in_subprocess
, on a host that has three IP addresses (one is 127.0.0.1, two is wifi,
three is a VPN). The test itself is getting skipped because bin/tahoe
isn't in the expected place, but by that point, the nodes have already
been launched and have established connections over one of the three
hints (probably 127.0.0.1). The test terminates so quickly that the
connections to the other two addresses have not finished being
abandoned. The extra stall seems to give Foolscap enough time to reap
the cancelled connections and makes the DRT go away.
I think an offline test, or maybe one with a single external IP address,
wouldn't hit this case.
Arbitrary stalls are never very satisfactory, of course. Usually there
is some threshold delay value, below which it fails reliably, above
which it works on my own machine (for now). This one is weird: the
threshold seems to be below the resolution of the system clock. Stalling
for one nanosecond was enough to fix the problem, but using a simple
fireEventually() didn't work.
This little-used debugging feature allowed you to SSH or Telnet "into" a
Tahoe node, and get an interactive Read-Eval-Print-Loop (REPL) that
executed inside the context of the running process. The SSH
authentication code used a deprecated feature of Twisted, this code had
no unit-test coverage, and I haven't personally used it in at least 6
years (despite writing it in the first place). Time to go.
Also experiment with a Twisted-style "topfiles/" directory of NEWS
fragments. The idea is that we require all user-visible changes to
include a file or two (named as $TICKETNUM.$TYPE), and then run a script
to generate NEWS during the release process, instead of having a human
scan the commit logs and summarize the changes long after they landed.
Closes ticket:2367
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
We only really need "Twisted >= 13.0.0", but we must add "[tls]" because
otherwise pip won't install it when Foolscap asks for it later, and we
need ">= 15.1.0" because that's the first version that provided "[tls]".
Fixes ticket:2760.
Thanks to dstufft for the suggestion. I know this can make it slightly
easier to run tahoe in some funny environments (where an appropriate
"python" is on your path but the generated "tahoe" executable is not).
Our install_requires= want foolscap>=0.10.1, and this check only fired
if we were given <0.6.4, so the check should be obsolete.
Also, the check was breaking my attempt to test Tahoe against a
development release of Foolscap, as the NormalizedVersion call threw an
IrrationalVersionError at my Versioneer-based "0.10.1+14.g37d8279"
version string.
This was used to exercise our old virtualenv-like scheme. Now that we
use virtualenv, they're unnecessary. Plus, removing it lets us stop
polluting end-user installs with the extra package (that might
conceivably conflict with some other project that names itself
"buildtest").
This allows a python3-based "tox" (as shipped with modern debian and
ubuntu systems) to run setup.py egg_info, update_version, and sdist
commands. It moves the main "tahoe requires py2" check out of setup.py
and into allmydata.scripts.runner.run, where it gets applied at runtime
rather than build time.
It also changes the execfile(_auto_deps.py) and Versioneer-like "ask git
what our version string should be" code to work under both py2 and py3.
fixes ticket:2747
We don't necessarily need this ourselves (__init__.py's version-checking
code is the only thing in tahoe per se that uses setuptools, and our
setup.py's use of setuptools isn't something that install_requires= can
say anything about). But at least one old environment failed because a
sub-dependency needed a newer version than Tahoe asked for. I'm not sure
if this ought to be here, but it may help for a transitional period
until these ancient environments get updated.
closes ticket:2744
20.3 is the current version as of today. I'm not really sure what
version we need, but this is better than the previous zetuptoolz "0.6c6"
requirement. Closes ticket:2744.
With our new tox/pip/virtualenv -based environment, we no longer need
the bin/tahoe script, so the tests that examine it needed to change.
In particular, we no longer need to be running tests from the root of a
source tree. Instead, what we care about is that the subprocess 'tahoe'
is importing code from the same place that the unit test .py files live.
NumDict does not make any claims about the order of its repr(), so the
test needs to be prepared for it to be stringified in any order. On unix
the old test happened to pass, but on certain windows boxes (maybe
certain versions of python?), it failed. Fixes ticket:2736.
I'm not sure why this ever existed, but it doesn't appear to be used.
(If an introducer called a client's set_encoding_parameters method it would
keep the provided parameters in an instance attribute but would not actually
use them.)
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.
