JoandVictor Cinaglia 06278615fb Fix: Increase login_attempt.ip_address column length for IPv6 support (#107035)
* fix: increase login_attempt.ip_address column length for IPv6 support

- Expand ip_address column from VARCHAR(30) to VARCHAR(50) to accommodate IPv6 addresses
- Add database migration with support for PostgreSQL, MySQL, and SQLite
- Add comprehensive integration tests for various IPv6 address formats
- Resolves 500 errors when login fails over IPv6, now returns proper 401 errors

Fixes #106362

* test: add missing test skip to TestIntegrationIPv6AddressSupport

Skip integration test when running with -short flag to separate unit and integration tests

* Update pkg/services/sqlstore/migrations/login_attempt_mig.go

* fix missing bracket

* fix: resolve PostgreSQL timestamp overflow in IPv6 test

- Use controlled time mock instead of time.Now() to avoid timestamp conversion issues
- Follow existing test patterns with xormStore and mock time functions
- Add proper Since parameter to GetIPLoginAttemptCount query
- Fixes PostgreSQL error: 'pq: value "-62135596800" is out of range for type integer'

* fix: resolve PostgreSQL UTF-8 encoding error in IPv6 test

Replace string(rune(i)) with fmt.Sprintf to avoid null bytes (0x00)
when i=0, which caused 'invalid byte sequence for encoding UTF8' error

License Drone Go Report Card

Grafana allows you to query, visualize, alert on and understand your metrics no matter where they are stored. Create, explore, and share dashboards with your team and foster a data-driven culture:

  • Visualizations: Fast and flexible client side graphs with a multitude of options. Panel plugins offer many different ways to visualize metrics and logs.
  • Dynamic Dashboards: Create dynamic & reusable dashboards with template variables that appear as dropdowns at the top of the dashboard.
  • Explore Metrics: Explore your data through ad-hoc queries and dynamic drilldown. Split view and compare different time ranges, queries and data sources side by side.
  • Explore Logs: Experience the magic of switching from metrics to logs with preserved label filters. Quickly search through all your logs or streaming them live.
  • Alerting: Visually define alert rules for your most important metrics. Grafana will continuously evaluate and send notifications to systems like Slack, PagerDuty, VictorOps, OpsGenie.
  • Mixed Data Sources: Mix different data sources in the same graph! You can specify a data source on a per-query basis. This works for even custom datasources.
