lnwire: update quickcheck tests, use constant for Error
multi: update unit tests to pass deep equal assertions with messages
In this commit, we update a series of unit tests in the code base to now
pass due to the new wire message encode/decode logic. In many instances,
we'll now manually set the extra bytes to an empty byte slice to avoid
comparisons that fail due to one message having an empty byte slice and
the other having a nil pointer.
In this commit, we migrate all wire messages in the database from the
`legacy` to the `current` encoding.
This affects the way we write the `CommitDiff` and `LogUpdates` struct
to disk. We also need to migrate the network results bucket in the
switch as it includes a wire message without a length prefix.
We copy the new serialization togic to a new package 'current' and
export the methods we will need from the migration. This ensures that we
have isolation between the legacy and current serialization methods,
cleanly inidcating what type we are using during the migration.
In this commit, we modify the way we write wire messages across the
entire database. We'll now ensure that we always write wire messages
with a length prefix. We update the `codec.go` file to always write a 2
byte length prefix, this affects the way we write the `CommitDiff` and
`LogUpdates` struct to disk, and the network results bucket in the
switch as it includes a wire message.
The legacy encoding depends on the lnwire21 version of lnwire, so it will
let us change lnwire after the migration. To make sure it is separated
from the new encoding, we add it to a new package 'legacy'.
We also put common types in a new package 'common', which will house
types that won't change during the migration, and can be used by both
legacy and current serialization code.
To avoid code changing underneath the static migrations, we copy the
lnwire dependency in its current form into the migration directory.
Ideally the migrations doesn't depend on any code that might change,
this takes us a step closer.
This commit adds support for etcd namespaces. This is useful when
using a shared etcd database where separate users have access to
separate namespaces.
Adds an outpoint index that stores a tlv stream. Currently the stream
only contains the outpoint's indexStatus. This should cut down on
big bbolt transactions in several places throughout the codebase.
Previously we wouldn't recreate some of the top level buckets that are
now considered expected with our migration logic. This bug was
preexisting, but never surfaced because the other TLB buckets were not
touched by this unit test.
* mod: bump btcwallet version to accept db timeout
* btcwallet: add DBTimeOut in config
* kvdb: add database timeout option for bbolt
This commit adds a DBTimeout option in bbolt config. The relevant
functions walletdb.Open/Create are updated to use this config. In
addition, the bolt compacter also applies the new timeout option.
* channeldb: add DBTimeout in db options
This commit adds the DBTimeout option for channeldb. A new unit
test file is created to test the default options. In addition,
the params used in kvdb.Create inside channeldb_test is updated
with a DefaultDBTimeout value.
* contractcourt+routing: use DBTimeout in kvdb
This commit touches multiple test files in contractcourt and routing.
The call of function kvdb.Create and kvdb.Open are now updated with
the new param DBTimeout, using the default value kvdb.DefaultDBTimeout.
* lncfg: add DBTimeout option in db config
The DBTimeout option is added to db config. A new unit test is
added to check the default DB config is created as expected.
* migration: add DBTimeout param in kvdb.Create/kvdb.Open
* keychain: update tests to use DBTimeout param
* htlcswitch+chainreg: add DBTimeout option
* macaroons: support DBTimeout config in creation
This commit adds the DBTimeout during the creation of macaroons.db.
The usage of kvdb.Create and kvdb.Open in its tests are updated with
a timeout value using kvdb.DefaultDBTimeout.
* walletunlocker: add dbTimeout option in UnlockerService
This commit adds a new param, dbTimeout, during the creation of
UnlockerService. This param is then passed to wallet.NewLoader
inside various service calls, specifying a timeout value to be
used when opening the bbolt. In addition, the macaroonService
is also called with this dbTimeout param.
* watchtower/wtdb: add dbTimeout param during creation
This commit adds the dbTimeout param for the creation of both
watchtower.db and wtclient.db.
* multi: add db timeout param for walletdb.Create
This commit adds the db timeout param for the function call
walletdb.Create. It touches only the test files found in chainntnfs,
lnwallet, and routing.
* lnd: pass DBTimeout config to relevant services
This commit enables lnd to pass the DBTimeout config to the following
services/config/functions,
- chainControlConfig
- walletunlocker
- wallet.NewLoader
- macaroons
- watchtower
In addition, the usage of wallet.Create is updated too.
* sample-config: add dbtimeout option
Similar to what we did for the local state handling, we extract handling
all known remote states we can act on (breach, current, pending state)
into its own method.
Since we want to handle the case where we lost state (both in case of
local and remote close) last, we don't rely on the remote state number
to check which commit we are looking at, but match on TXIDs directly.
This change was largely motivated by an increase in high disk usage as a
result of channel update spam. With an in memory graph, this would've
gone mostly undetected except for the increased bandwidth usage, which
this doesn't aim to solve yet. To minimize the effects to disks, we
begin to rate limit channel updates in two ways. Keep alive updates,
those which only increase their timestamps to signal liveliness, are now
limited to one per lnd's rebroadcast interval (current default of 24H).
Non keep alive updates are now limited to one per block per direction.
This commit adds the compaction feature of the bbolt compact to our bolt
backend. This will try to open the DB in read-only mode and create a
compacted copy in a temporary file. Once the compaction was successful,
the temporary file and the old source file are swapped atomically.
Similarly as with kvdb.View this commits adds a reset closure to the
kvdb.Update call in order to be able to reset external state if the
underlying db backend needs to retry the transaction.
This commit adds a reset() closure to the kvdb.View function which will
be called before each retry (including the first) of the view
transaction. The reset() closure can be used to reset external state
(eg slices or maps) where the view closure puts intermediate results.
This commit adds commitQueue which is a lightweight contention manager
for STM transactions. The queue attempts to queue up transactions that
conflict for sequential execution, while leaving all "unblocked"
transactons to run freely in parallel.
