Another release, but this time not (only) a bugfix one. After playing with bool semantics I converted the file tests from a _X format, which, let's face it, was not pretty, into the more usual -X format. This alone merits a change in the minor version number. Also, _in, _out and _err also accept a tuple (path, flags), so you can specify things like os.O_APPEND.

In other news, I had to drop support for Pyhton-3.3, because otherwise I would have to complexify the import system a lot.

But in the end, yes, this also is a bugfix release. Lost of fd leaks where plugged, so I suggest you to upgrade if you can. Just remember the s/_X/-X/ change. I found all the leaks thanks to unitest's warnings, even if sometimes they were a little misleading:

testRemoteCommandStdout (tests.test_remote.RealRemoteTests) ... ayrton/parser/pyparser/parser.py:175: <span class="createlink">ResourceWarning</span>: unclosed <socket.socket fd=5, family=AddressFamily.AF_UNIX, type=SocketKind.SOCK_STREAM, proto=0, raddr=/tmp/ssh-XZxnYoIQxZX9/agent.7248>
  self.stack[-1] = (dfa, next_state, node)

The file and line cited in the warning have nothing to do with the warning itself (it was not the one who raised it) or the leaked fd, so it took me a while to find were those leaks were coming from. I hope I have some time to find why this is so. The most frustrating thing was that unitest closes the leaking fd, which is nice, but in one of the test cases it was closing it seemingly before the test finished, and the test failed because the socket was closed:

This probably has something to do with the fact that the test (a functional test, really) is using threads and real sockets. Again, I'll try to investigate this.

All in all, the release is an interesting one. I'll keep adding small features and releasing, let's see how it goes. Meanwhile, here's the changelog:

  • The 'No Government' release.
  • Test functions are no longer called _X but -X, which is more scripting friendly.
  • Some if those tests had to be fixed.
  • Dropped support for py3.3 because the importer does not work there.
  • tox support, but not yet part of the stable test suite.
  • Lots and lots of more tests.
  • Lots of improvements in the remote() tests; in particular, make sure they don't hang waiting for someone who's not gonna come.
  • Ignore ssh remote() tests if there's not password/phrase-less connection.
  • Fixed several fd leaks.
  • _in, _out and _err also accept a tuple (path, flags), so you can specify things like os.O_APPEND. Mostly used internally.

Get it on github or pypi!
