* feat: new metadata backup endpoint
* feat: added restore/sql API endpoint
* fix: content-type is multipart/mixed, part names are kv and sql
* fix: changed multipart manifest to buckets and made it .json
* feat: added lock for backing up sqlite and bolt dbs
* fix: use read lock instead of write lock on kv during backup
* fix: use filepath.Join for temp dirs
* refactor: migrator and introduce Store.(Create|Delete)Bucket
feat: kvmigration internal utility to create / managing kv store migrations
fix: ensure migrations applied in all test cases
* chore: update kv and migration documentation
This new session service has the ability to work independant of other systems
it relies on having its own store type which should allow us to be more flexible
then using the built in kv system.
I have included an in mem session store.
* feat(kv): migration types for managing kv buckets and indexes over time
chore(kv): fixup comments in migrator types
fix(kv): initialize migrator bucket on kv service initialize
chore(kv): remove currently unused auth index
chore(kv): remove currently unused urm index
* chore(kv): move migrator tests into testing package and run for inmem and bolt
* chore(changelog): update changelog to reflect kv migrator type
* fix(kv): update auto migration store to return migratable store
* chore(kv): wrap error using func instead of defer in index
* chore(kv): rename Name method to MigrationName for clarity
* chore(kv): update migration log messages to match influxdb standard
* fix(kv): Update scrapers to use new forward cursor
I also made a minor update to move a db lookup outside of a for loop to save
time and optimize
* fix(inmem): fix a potential race condition
* feat(backup): `influx backup` creates data backup
* feat(backup): initial restore work
* feat(restore): initial restore impl
Adds a restore tool which does offline restore of data and metadata.
* fix(restore): pr cleanup
* fix(restore): fix data dir creation
* fix(restore): pr cleanup
* chore: amend CHANGELOG
* fix: restore to empty dir fails differently
* feat(backup): backup and restore credentials
Saves the credentials file to backups and restores it from backups.
Additionally adds some logging for errors when fetching backup files.
* fix(restore): add missed commit
* fix(restore): pr cleanup
* fix(restore): fix default credentials restore path
* fix(backup): actually copy the credentials file for the backup
* fix: dirs get 0777, files get 0666
* fix: small review feedback

A KV store may optionally implement a key predicate
function to filter on keys or values, which may reduce memory and
CPU usage.

* feat(auth): add createdAt and updatedAt to authorization
Co-Authored-By: Ariel <ariel.salem1989@gmail.com>
* feat(auth): passing createAuth tests
* test: ensured that createdAt and updatedAt are valid on authorizations
* feat(kv): unique variable names
- adds system bucket for creating an index of unique variable names
- adds tests
- deleted unit tests for dead code
- removed a test runner for the variable service from http
Implementations of the `kv.Bucket#Cursor` API may use
the hints to instruct the access or read behavior to
the underlying key/value store.
The `findAllTasks` function was also fixed to ensure
that paging works as expected when using a name filter.
Tests were added to verify this behavior.
Redundant error checks were also removed.
The http error schema has been changed to simplify the outward facing
API. The `op` and `error` attributes have been dropped because they
confused people. The `error` attribute will likely be readded in some
form in the future, but only as additional context and will not be
required or even suggested for the UI to use.
Errors are now output differently both when they are serialized to JSON
and when they are output as strings. The `op` is no longer used if it is
present. It will only appear as an optional attribute if at all. The
`message` attribute for an error is always output and it will be the
prefix for any nested error. When this is serialized to JSON, the
message is automatically flattened so a nested error such as:
influxdb.Error{
Msg: errors.New("something bad happened"),
Err: io.EOF,
}
This would be written to the message as:
something bad happened: EOF
This matches a developers expectations much more easily as most
programmers assume that wrapping an error will act as a prefix for the
inner error.
This is flattened when written out to HTTP in order to make this logic
immaterial to a frontend developer.
The code is still present and plays an important role in categorizing
the error type. On the other hand, the code will not be output as part
of the message as it commonly plays a redundant and confusing role when
humans read it. The human readable message usually gives more context
and a message like with the code acting as a prefix is generally not
desired. But, the code plays a very important role in helping to
identify categories of errors and so it is very important as part of the
return response.
At times snowflake id generation would create org and bucket IDs with
characters that had special meaning for the storage engine.
The storage engine concats the org and bucket bytes together into a
single 128 bit value. That value is used in the old measurement
section. Measurement was transformed into the tag, _measurement.
However, certain properties of the older measurement data location
are still required for the org/bucket bytes. We cannot have
commas, spaces, nor backslashes.
This PR puts a specific ID generator in place during the creation of
orgs and buckets. The IDs are just random numbers but with each
of the restricted chars incremented by one. While this changes the
entropy distribution somewhat, it does not matter too much for our
purposes.
... because now org and bucket ids are checked for previous existence
transactionally in the key-value stores. If the ID does already exist
then we try to generate a new key up to 100 times.
