Clear memcached when tools/run-dev.py is run. This prevents
errors on using a different python version because values are
pickled before being stored in memcached and different python
versions implement pickling differently.
Also provide a command-line option --no-clear-mc to prevent
memcached from being cleared.
tools/provision.py: Create directory var/uploads.
zproject/local_settings_template.py: Update Upload dir to var/uploads.
zproject/dev_settings.py: Update upload dir to var/uploads.
The muting logic in approximate_unread_count() was confusing
stream/subject and only using the first of many stream/subject
pairs, so it was rarely excluding rows from the count, and when
it did exclude rows, they were the wrong rows.
This fixes part of #1300, but we may want to keep the issue open.
This dependency is only needed if USING_STATSD is set, and so had
apparently been missed from our dependency list previously (since few
sites use that setting).
There is a hard to reproduce race condition causing these tests to
occasionally fail. We believe it is caused by switching to the home tab and
not properly waiting for all the messages to load; see Issue #1243. The
tests are for the following pathway (not a high priority to test):
1. User starts editing a message.
2. allow_message_editing is turned off for the realm (in this case, by the
user going to the admin page and turning it off).
3. User finishes editing the message and hits send.
Running `./manage.py email-mirror` used to fail on python 3
because twisted.mail.imap4 is not python 3 compatible.
Display a message informing the user that email-mirror is not
available on python 3 instead of failing with a traceback.
Also add tools/test-management to py3-backend.
runtornado unbuffers its output using
sys.stdout = os.fdopen(sys.stdout.fileno(), 'w', 0).
This is not python 3 compatible since we can't specify
buffering on a text stream in python 3. So use the '-u'
option of python when calling runtornado.py to make output
unbuffered.
