py3: drop encoding.strio()
Its buffered nature makes TextIOWrapper unsuitable for temporarily wrapping
bytes I/O.
ui: adjust Windows workaround to new _readline() code
It's only needed when rawinput() is called. Also made it Py3 compatible.
ui: do not use rawinput() when we have to replace sys.stdin/stdout
See the inline comment for why. The current Python3 hack doesn't work if
more than one user inputs are expected because TextIOWrapper fills its
internal buffer at the first read() request.
Maybe we could write an unbuffered TextIOWrapper, but I don't want to make
things more complicated. Instead, this patch reinvents raw_input(' ') of
no readline support.
ui: do not try readline support if fin/fout aren't standard streams
It's unlikely for a non-stdio stream to be a tty. Minimizing readline support
makes it much simpler to work around the unicode input() function of Python 3.
This also works on chg which duplicates client's tty to stdio fds.
ui: add debug commands to test interactive prompt
Interactive operations aren't easily covered by tests. So let's add commands
to test them manually.
ui: inline util.bytesinput() into ui._readline()
Prepares for rework of Python 3 support, which is currently broken due to
read-ahead buffer of TextIOWrapper.
hgk: stop using util.bytesinput() to read a single line from stdin
Appears that the stdio here is an IPC channel between hg and hgk (tk)
processes, which shouldn't need a fancy readline support.
bookmarks: test for exchanging long bookmark names (
issue5165)
As far as I can tell a test for a long bookmark name never actually
got added when this was fixed. Let's document that a 300 byte bookmark
is something we're supporting (this patch started out life over a year
ago as a way for me to validate the problem, and I recently found it.)
I think the nonzero exits from the push operations are only because no
new changesets get exchanged. Please correct me if I'm wrong on that. :)

phabricator: follow-up phab auth improvements with backwards compat mode
We'll rip this out before we ship 4.6, but this gives people a window
to migrate.
