When we call ordersStore.BeginEnqueue, the unsent orders file for that
satellite and hour is prevented from being sent. It is freed when the
commit callback returned by BeginEnqueue is used. This change ensures
that we always call the commit callback, even when we have an empty
order or an order with Amount <= 0.

This change accomplishes multiple things:
1. Instead of having a max in flight time, which means
we effectively have a minimum bandwidth for uploads
and downloads, we keep track of what windows have
active requests happening in them.
2. We don't double check when we save the order to see if it
is too old: by then, it's too late. A malicious uplink
could just submit orders outside of the grace window and
receive all the data, but the node would just not commit
it, so the uplink gets free traffic. Because the endpoints
also check for the order being too old, this would be a
very tight race that depends on knowledge of the node system
clock, but best to not have the race exist. Instead, we piggy
back off of the in flight tracking and do the check when
we start to handle the order, and commit at the end.
3. Change the functions that send orders and list unsent
orders to accept a time at which that operation is
happening. This way, in tests, we can pretend we're
listing or sending far into the future after the windows
are available to send, rather than exposing test functions
to modify internal state about the grace period to get
the desired effect. This brings tests closer to actual
usage in production.
4. Change the calculation for if an order is allowed to be
enqueued due to the grace period to just look at the
order creation time, rather than some computation involving
the window it will be in. In this way, you can easily
answer the question of "will this order be accepted?" by
asking "is it older than X?" where X is the grace period.
5. Increases the frequency we check to send up orders to once
every 5 minutes instead of once every hour because we already
have hour-long buffering due to the windows. This decreases
the maximum latency that an order will be reported back to
the satellite by 55 minutes.

On run, write the storage directory verification file.
Every time the node runs it will write the file even if it already exists.
The reason we do this is because if the verification file is missing, the SN
doesn't know whether it is an incorrect directory, or it simply hasn't written
the file yet, and we want to keep nodes running without needing operator intervention.
Once this change has been a part of the minimum version for several releases,
we will move the file creation from the run command to the setup
command. Run will only verify its existence.
Change-Id: Ib7d20e78e711c63817db0ab3036a50af0e8f49cb
Sometimes SNOs fail to properly configure or lose connection to their storage directory
which can result in DQ. This causes unnecessary repair and is unfortunate for all parties.
This change introduces the creation of a special file in the storage directory at runtime
containing the node ID. While the storage node runs, it periodically verifies that it can
find said file with the correct contents in the correct location. If not, the node will
shut down with an error message.
This change will solve the issue of nodes losing access to the storage directory, but it will not
solve the issue of nodes pointing to the wrong directory, as the identifying file is created each
time the node starts up. After this change has been the minimum version for a few releases, we will
remove the creation of the directory-identifying file from the storage node run command and add it
to the setup command.

orders if they exist. In a later release, we will completely remove the
orders DB, but we need both the DB and filestore for the transitionary

If free disk < than expected available space, return free disk.

When an uplink or repair work finishes uploading a piece to a
storagenode, it has no reason to wait another round trip after the piece
is committed to gracefully close the connection - in many (most?) cases,
the connection is simply canceled once the upload is complete. This has
the unintended side effect of producing a lot of "piece canceled" logs
and metrics on the storagenode side, when the reality is that the piece
uploads were successful, and not really canceled. This commit fixes
that.

it was noticed that if you had a long lived transaction A that
was blocking some other transaction B and A was being aborted
due to retriable errors, then transaction B was never given
priority. this was due to using savepoints to do lightweight
retries.
this behavior was problematic becaue we had some queries blocked
for over 16 hours, so this commit addresses the issue with two
prongs:
1. bound the amount of time we will retry a transaction
2. create new transactions when a retry is needed
the first ensures that we never wait for 16 hours, and the value
chosen is 10 minutes. that should be long enough for an ample
amount of retries for small queries, and huge queries probably
shouldn't be retried, even if possible: it's more preferrable to
find a way to make them smaller.
the second ensures that even in the case of retries, queries that
are blocked on the aborted transaction gain priority to run.
between those two changes, the maximum stall time due to retries
should be bounded to around 10 minutes.

Introduce tagsql.Open which helps to get rid of all tagsql.Wrap-s.
Use tagsql in cockroachkv and postgreskv.

Migration step was closing a database that was used by
the migration itself. There is an active tranasction
over the database.
Instead of closing in the same transaction we can wait
until restart for the database cleanup.

Also added temporary types withRebind and withTagTx,
which will be later removed. Currently they help to avoid
changing the whole codebase at the same time.

storagenode database preflight check.
Disable preflight database check by default, and have the option to
enable it. This will allow us to enable it once it is definitely
working.
Also change the name of the config flag for preflight time sync.

On pieces usage cache init we now load the trash info from the db. Also
fixes a test that was masking the failure here.

for storagenode
Ensure that database schema matches latest test migration schema before
allowing the node to start up.
Ensure minimal read/write functionality for each storagenode database
before allowing the node to start up.
This will eliminate many unhandled audit errors we are seeing.

This reverts commit 8e242cd012.
Revert because lib/pq has known issues with context cancellation.
These issues need to be resolved before these changes can be merged.

this will allow for some nice runtime analysis down the road.
also, this allows for wrapping database handles in a way that
can interact with these contexts

When error is formatted using %v it's not possible to check
whether the error was caused by a context cancellation.

This code needs to work against cockroachDB, so transactions must be retried
when a retryable error is returned. This change puts migrate
transactions into the dbutil.WithTx transactional helpers to achieve
this in the easiest way.

Remove starting up messages from peers. We expect all of them to start,
if they don't, then they should return an error why they don't start.
The only informative message is when a service is disabled.
When doing initial database setup then each migration step isn't
informative, hence print only a single line with the final version.
Also use shorter log scopes.

Remove direct dependency on uplink.RSConfig, this simplifies
moving the config file without introducing weird dependencies.

This commit adds functionality to include the space used in the trash
directory when calculating available space on the node.
It also includes this trash value in the space used cache, with methods
to keep the cache up-to-date as files are trashed, restored, and
emptied.
As part of the commit, the RestoreTrash and EmptyTrash methods have
slightly changed signatures. RestoreTrash now also returns the keys that
were restored, while EmptyTrash also returns the total disk space
recovered. Each of these changes makes it possible to keep the cache
up-to-date and know how much space is being used/recovered.
Also changed is the signature of PieceStoreAccess.ContentSize method.
Previously this method returns only the content size of the blob,
removing the size of any header data. This method has been renamed
`Size` and returns both the full disk size and content size of the blob.
This allows us to only stat the file once, and in some instances (i.e.
cache) knowing the full file size is useful.
Note: This commit simply adds the trash size data to the piece size data
we were already collecting. The piece size data is not accurate for all
use-cases (e.g. because it does not contain piece header data); however,
this commit does not fix that problem. Now that the ContentSize (Size)
method returns the full size of the file, it should be easier to fix
this problem in a future commit.

Fixes a data race caused by not waiting for workers to finish
before shutting down. Currently this ended up failing logging
because it was closed when test tried to write to it.
