Previously, it would treat anything that wasn't (case insensitively)
equal to "true" as False. The new configparser will ensure that the
value is either "true" or "false" and not "slkdjfljksdf", reducing the
risk of accidental False by typo.
The dynamic configuration system has two components: the app, which
reads, and the writer script. The latter is meant for use by humans, and
converts a [live_config] section of the INI file into JSON for storage
in ZooKeeper. The app will read this data on startup and place a watch
on the node to be notified, by ZooKeeper, of changes. This means that
running the writer script with new data will automatically propagate the
changes to every app very quickly, without restart.
The writer script relies on a human-entered password to authenticate
with ZooKeeper. The reddit app uses a different set of credentials
(specified in the INI file) to obtain read-only access to the
configuration data.
Also adds a new "live_config" spec to reddit and plugins. This spec is
parsed at write-time only and the parsed values are stored as JSON in
ZooKeeper.
The first phase loads the entry points and instantiates plugin objects.
This phase is useful for inspecting plugin metadata without having a
full environment configured (routing etc.). This phase is moved earlier
in the init process, to the first moment after the configuration has
been parsed.
The second phase does the heavy work of making individual plugins inject
themselves into the otherwise ready reddit environment. This phase stays
where plugin loading took place before (after global setup).
Uses both transaction id and campaign id to uniquely identify a bid. This
fixes a bug where querying for one bid in some cases caused a multiple rows
returned exception - a side effect of the campaign migration, which left both
old and new bids in the db.
This change also includes the campaign id when attempting to recreate a lost
bid record because... bid records are supposed to have campaign ids. I'm not
sure what was happening with the bid records that didn't.
This check was raising a value error if run on the 31st against an expiration
date in a month that only had 30 days. Now we pick the 1st day of the month,
which is guaranteed to exist.
Also uses the correct timezone.
There have been some None object has no date() attribute errors in the logs.
Not sure how one of start/end are being set to None and not the other, but
went ahead and moved the call to date() inside the conditional that checks
whether both exist to make sure the correct error message gets set.
Makes get_schedule return a list of errored campaigns instead of just logging
them so they can be handled by the calling function.
Updates make_daily_promotions to first launch as many campaigns as possible,
then raise an exception with a list of errors at the end. The exception is
useful for triggering alerts.

When getting a list of user subreddits, we'll check if they're
subscribed to any automatic subreddits and remove them from the mix
before doing the random selection. Then they'll be added back in. This
is important to ensure that maintenance announcements aren't missed by
users because the announcement wasn't in their subset of subscriptions.
On reddit.com the automatic subreddits are /r/blog and /r/announcements.
Some evil people are using the toolbar URLs to spam their links and then
framebusting to ditch the toolbar. This patch makes it so that if the
framed URL is on a shame-banned domain, the framing will abort and
return a 404.
This will allow us to collect information about how users found
subreddits that they subscribe to. We can use this information to test
the effectiveness of new ways of discovering and subscribing to
subreddits.
Specifically, when the subscribe button is clicked, for the current page
and previous page: the URL, referrer URL, and the type of UI element
clicked are sent. We'll use this to answer questions like:
* "did clicking on gizmo A lead to users subscribing to subreddit B?"
* "why did we see a spike in subscriptions to subreddit X today?"
The "Read from PromoCampaign things" change broke the code that causes the
traffic display to show the past month by default if a promoted link has
no campaigns.
This change fixes a bug where clicking on "traffic" on one of the subreddit
discovery spotlight links caused a 500 error.

Aggressively catches and logs exceptions inside the campaign loop in
get_scheduled. This change will allow make_daily_promotions to skip over
campaigns with corrupt data and still launch the others.
Note: We might want to consider passing the list of errored campaigns
back up to the calling function so they can be handled more noisily there.
In memcached there is a chance of the keys being evicted before their
time runs out. We can mitigate this by adding more memcaches, but that
has other downsides (such as increased risk of failure).
Pycassa will do its own marshalling when columns have validators
specified in the C* metadata. We need to disable our own marshalling
when we know Pycassa will take care of it. This is already taken care of
in the general case, but timestamps are handled somewhat uniquely.
This provides a system for two-factor authentication, using a compliant
OTP-generator such as Google Authenticator. The framework includes a
validator for use on API calls needing authentication as well as a UI
for provisioning/resetting your secret key. A secure cookie may be
generated to effectively turn the user's browser into a temporary
authentication factor.
This feature is currently limited to admins only until full-site SSL is
available.
If the config variable profile_directory is set, ProfilingMiddleware
will be added to the WSGI stack. The middleware will generate a file in
the specified directory on each request containing the contents of that
request's profile.
