We are in the process of creating an api to allow users to manage their
accounts programmatically. We would like to use api keys for
authorization. We were originally going to create an entirely new table
for these api keys, but seeing as we already have 2 other tables for
keys/tokens, api_keys and oauth_tokens, we thought it might be better to
use one of these. We're using oauth_tokens.
We create a new oidc.OAuthTokenKind for account management api keys:
KindAccountManagementTokenV0. We made the key versioned because we
likely want to improve the implementation in the future, but we want to
get something functional out the door ASAP because the account management
api feature is highly desired.
Add a new method to oidc.OAuthTokens interface for revoking v0 account
management api keys, RevokeAccountManagementTokenV0. Add update method
to dbx implementation to allow updating the expiration. We will revoke
these keys by setting the expiration to 0 so they are expired.

All code on known satellites at this moment in time should know how to
populate and use the new numeric columns on the
stripecoinpayments_tx_conversion_rates and coinpayments_transactions
tables in the satellite db. However, there are still gob-encoded
big.Float values in the database from before these columns existed. To
get rid of those values, so that we can excise the gob-decoding code
from the relevant sections, however, we need something to read the gob
bytestrings and convert them to numeric values, a few at a time, until
they're all gone.
To accomplish that, this change adds two chores to be run in the
satellite core process- one for the coinpayments_transactions table, and
one for the stripecoinpayments_tx_conversion_rates table. They should
run relatively infrequently, so that we do not impose any undue load on
processing resources or the db.
Both of these chores work without using explicit sql transactions, but
should still be concurrent-safe, since they work by way of
compare-and-swap type operations.
If the satellite core process needs to be restarted, both of these
chores will start scanning for migrateable rows from the beginning of
the id space again. This is not ideal, but shouldn't be a problem (as
far as I can tell, there are only a few thousand rows at most in either
of these tables on any production satellite).

For a thorough explanation of the overall transition, see the message on
commit c053bdbd70.
This change will rename the columns containing gob-encoded big.Floats
and add new columns which will contain the equivalent data in a more
sql-friendly format.
The change should *not* break already-running satellite processes,
because all functionality touching these tables has already been taught
to work with these new columns if it sees any "undefined column" errors.

This change adds some more checks to the deletion process for projects and

while also allowing the deletion of projects/users on free tier during the month.

Why: big.Float is not an ideal type for dealing with monetary amounts,
because no matter how high the precision, some non-integer decimal
values can not be represented exactly in base-2 floating point. Also,
storing gob-encoded big.Float values in the database makes it very hard
to use those values in meaningful queries, making it difficult to do
any sort of analysis on billing.
Now that we have amounts represented using monetary.Amount, we can
simply store them in the database using integers (as given by the
.BaseUnits() method on monetary.Amount).
We should move toward storing the currency along with any monetary
amount, wherever we are storing amounts, because satellites might want
to deal with currencies other than STORJ and USD. Even better, it
becomes much clearer what currency each monetary value is _supposed_ to
be in (I had to dig through code to find that out for our current
monetary columns).
Deployment
----------
Getting rid of the big.Float columns will take multiple deployment
steps. There does not seem to be any way to make the change in a way
that lets existing queries continue to work on CockroachDB (it could be
done with rules and triggers and a stored procedure that knows how to
gob-decode big.Float objects, but CockroachDB doesn't have rules _or_
triggers _or_ stored procedures). Instead, in this first step, we make
no changes to the database schema, but add code that knows how to deal
with the planned changes to the schema when they are made in a future
"step 2" deployment. All functions that deal with the
coinbase_transactions table have been taught to recognize the "undefined
column" error, and when it is seen, to call a separate "transition shim"
function to accomplish the task. Once all the services are running this
code, and the step 2 deployment makes breaking changes to the schema,
any services that are still running and connected to the database will
keep working correctly because of the fallback code included here. The
step 2 deployment can be made without these transition shims included,
because it will apply the database schema changes before any of its code
runs.
Step 1:
No schema changes; just include code that recognizes the
"undefined column" error when dealing with the
coinbase_transactions or stripecoinpayments_tx_conversion_rates
tables, and if found, assumes that the column changes from Step
2 have already been made.
Step 2:
In coinbase_transactions:
* change the names of the 'amount' and 'received' columns to
'amount_gob' and 'received_gob' respectively
* add new 'amount_numeric' and 'received_numeric' columns with
INT8 type.
In stripecoinpayments_tx_conversion_rates:
* change the name of the 'rate' column to 'rate_gob'
* add new 'rate_numeric' column with NUMERIC(8, 8) type
Code reading from either of these tables must query both the X_gob
and X_numeric columns. If X_numeric is not null, its value should
be used; otherwise, the gob-encoded big.Float in X_gob should be
used. A chore might be included in this step that transitions values
from X_gob to X_numeric a few rows at a time.
Step 3:
Once all prod satellites have no values left in the _gob columns, we
can drop those columns and add NOT NULL constraints to the _numeric
columns.

Why: big.Float is not an ideal type for dealing with monetary amounts,
because no matter how high the precision, some non-integer decimal
values can not be represented exactly in base-2 floating point. Also,
storing gob-encoded big.Float values in the database makes it very hard
to use those values in meaningful queries, making it difficult to do
any sort of analysis on billing.
For better accuracy, then, we can just represent monetary values as
integers (in whatever base units are appropriate for the currency). For
example, STORJ tokens or Bitcoins can not be split into pieces smaller
than 10^-8, so we can store amounts of STORJ or BTC with precision
simply by moving the decimal point 8 digits to the right. For USD values
(assuming we don't want to deal with fractional cents), we can move the
decimal point 2 digits to the right.
To make it easier and less error-prone to deal with the math involved, I
introduce here a new type, monetary.Amount, instances of which have an
associated value _and_ a currency.

Satellites set their configuration values to default values using
cfgstruct, however, it turns out our tests don't test these values
at all! Instead, they have a completely separate definition system
that is easy to forget about.
As is to be expected, these values have drifted, and it appears
in a few cases test planet is testing unreasonable values that we
won't see in production, or perhaps worse, features enabled in
production were missed and weren't enabled in testplanet.
This change makes it so all values are configured the same,
systematic way, so it's easy to see when test values are different
than dev values or release values, and it's less hard to forget
to enable features in testplanet.
In terms of reviewing, this change should be actually fairly
easy to review, considering private/testplanet/satellite.go keeps
the current config system and the new one and confirms that they
result in identical configurations, so you can be certain that
nothing was missed and the config is all correct.
You can also check the config lock to see what actual config
values changed.

The previously configured never-expiring coupon does not refill every
month. Eventually, even though it never expires, it will run out. This
commit makes several small changes to address this issue for the free
tier:
* Change the config for the promotional coupon to be $1.65 for 1 month
(the change from $10 to $1.65 is due to our recent pricing changes)
* Update PopulatePromotionalCoupons (PPC for brevity) to add promotional
coupons to users with expired and consumed coupons (all users with a
project and no active coupons should get a new coupon when PPC is called)
* Call PPC at the end of the `create-invoice-coupons` stage of invoice
generation - after current coupons are processed and expired/exhausted.
* Remove legacy admin functionality for PPC from satellite/console - we
do not currently use it, but if we did, it should be in satellite/admin

Adopters, etc.)
So far the discounts were applied in the above order. But because the
Stripe discount is applied on all of the project usage fees, this could
sometimes lead to negative total in the invoice. Especially, if the
Stripe discount is 100% or all of the project fees are covered by
coupons and bonus.
To resolve this issue, before applying promotional coupons and deposit
bonuses, the Stripe discount will be applied first to the project fees.

Before:
- Discount from coupon: Promotional credits (limited time -
2 billing periods)
- Discount from credits
After:
- Promotional credits (limited time - 2 billing periods)
- Credits from STORJ deposit bonus
This way we don't mix the terms coupon and credit. And it is clearer
when the credit comes from a deposit bonus.

The billing history currently shows the Total amount from the Stripe
invoice. In fact, this value is just the amount deducted from the Stripe
balance. It does not reflect any deduction from promotional coupon or
bonus credits.
This patch adds the deducted amount form the promotional coupons and
bonus credits to the displayed amount in billing history. This way
customers have better understading of the total amount deducted from
their account balance on the satellite.

CustomerRepositoryList relied on created at time for the output sorting,
however the granularity of the timer may cause multiple customers
having the same "created at" time.
Add a sleep so that every customer does get a unique time.

this commit updates our monkit dependency to the v3 version where
it outputs in an influx style. this makes discovery much easier
as many tools are built to look at it this way.
graphite and rothko will suffer some due to no longer being a tree
based on dots. hopefully time will exist to update rothko to
index based on the new metric format.
it adds an influx output for the statreceiver so that we can
write to influxdb v1 or v2 directly.
