On windows, only one process can open a file in write mode at once. We
didn't close the handle we got (self._oshandle) before _cleanup, which
means that we had the file open the whole time, which means that the
external editor couldn't write back the changes.
This patch closes the file while the external editor is running and only
opens it once the editor is closed. We re-opened the file anyway, so
this shouldn't be a huge change. Additionally, tempfile.NamedTemporaryFile
is used instead of mkstemp, as we don't have to deal with os-level file
handles that way.
Completion.empty existed to fill a slot in the old Command.completions
interface if the first positional arg had no completions but the second
did, as is the case for the `bind` command. Now that
`Command.completions` is replaced by `Command.get_pos_arg_info`, this
is no longer needed.
Command completion types are now identified by ArgInfo, so just use
that directly and cut out the middle-man. This shouldn't change any
completion behavior.
Adds a test for get_pos_arg_info to test_cmdutils.
Modifies test_completer to test the use of get_pos_arg_info. Instead of
using FakeCommand, real Command objects are used, to validate that the
Completer works with the real Command interface. This also cleans out
some test cases that were testing things already covered by other cases.
Changes :yank's flag arguments to a positional "what" argument
specifying the object to be yanked. Including "selection" as a
possibility allows for the replacement of :yank-selected with
:yank selection.
This is a more rigorous test than filterAcceptsRow as it tests behavior
with multiple columns and different sort settings. In addition, it
tests intelligentLessThan which is not tested in the filterAcceptsRow
test (as lessThan is never called if there is only 1 item to filter).
With QtWebKit or QtWebEngine with Qt < 5.7, the functions end up in the
page's namespace. We can't easily avoid this, but at least we can name
them in a way which reduces conflicts.
