github.com/dgrijalva/jwt-go package is not referenced in any transitive
dependency anymore which allows us to remove one of the replace directives
which was added as a security precaution before.
We want `context.TODO()` to be high signal in the code-base. It should
signal clearly that work is required to thread parent context through to
the call-site. So to keep the signal-to-noise ratio high, we remove any
context.TODO() calls from tests since these will never need to be
replace by a parent context.
After this commit, there is only a single context.TODO() left in the
code-base.
In this commit, we make a change that enables the `auto_vacuum =
incremental` pragma for SQLite databases, but only when the database
file is first created. Incremental auto-vacuum allows SQLite to reclaim
unused space within the database file over time, preventing indefinite
growth.
Find and replace all nolint instances refering to the `lll` linter and
replace with `ll` which is the name of our custom version of the `lll`
linter which can be used to ignore log lines during linting.
The next commit will do the configuration of the custom linter and
disable the default one.
In this commit, we remove the global application level lock from the
postgres backend. This lock prevents multiple write transactions from
happening at the same time, and will also block a writer if a read is on
going. Since this lock was added, we know always open DB connections
with the strongest level of concurrency control available:
`LevelSerializable`. In concert with the new auto retry logic, we ensure
that if db transactions conflict (writing the same key/row in this
case), then the tx is retried automatically.
Removing this lock should increase perf for the postgres backend, as now
concurrent write transactions can proceed, being serialized as needed.
Rather then trying to handle concurrency at the application level, we'll
set postgres do its job, with the application only needing to retry as
necessary.
Previously our RPC calls to etcd would hang even in the case of properly
set dial timeouts and even if there was a network partition. To ensure
liveness we need to make sure that calls fail correctly in case of
system failure. To fix this we add a default timeout of 30 seconds to
each etcd RPC call.
In this commit, we update the project and relevant sub-modules to sqldb
v1.0.2. The next step is to tag a new version of kvdb, then update the
main module to use that.
In this commit, we fix a bug that would cause the entire db to shutdown
if hit a panic (since db operations in the main buckets exit with a
panic) while executing a txn call back. This might be a postgres error
we need to check, so we don't want to bail out, and instead want to pass
up the error to the caller so we can retry if needed.
Some sub-systems like btcwallet will return an error from the database,
but they won't properly wrap it. As a result, we were unable to actually
catch the serialization errors in the first place. To work around this,
we'll now attempt to parse the error string directly.
