Move source-related queries from `Invoke()` function into Source.
This is an effort to generalizing tools to work with any Source that
implements a specific interface. This will provide a better segregation
of the roles for Tools vs Source.
Tool's role will be limited to the following:
* Resolve any pre-implementation steps or parameters (e.g. template
parameters)
* Retrieving Source
* Calling the source's implementation
Along with these updates, this PR also resolve some comments from
Gemini:
* update `fmt.Printf()` to logging as a Debug log and remove the
training `\n` within the log
* move `regexp.MustCompile` to the top so that it's compiled once at the
package level and reused. It is a relatively expensive operation to be
called on every invocation.
* `fetchInstanceData()` to return the `*sqladmin.DatabaseInstance`
struct directly instead of converting to map and use map lookups. More
typesafe and efficient.
Did not move `cloudsqlpgupgradeprecheck` tool since that invocation is
very specific towards cloudsql for postgres
This PR update the linking mechanism between Source and Tool.
Tools are directly linked to their Source, either by pointing to the
Source's functions or by assigning values from the source during Tool's
initialization. However, the existing approach means that any
modification to the Source after Tool's initialization might not be
reflected. To address this limitation, each tool should only store a
name reference to the Source, rather than direct link or assigned
values.
Tools will provide interface for `compatibleSource`. This will be used
to determine if a Source is compatible with the Tool.
```
type compatibleSource interface{
Client() http.Client
ProjectID() string
}
```
During `Invoke()`, the tool will run the following operations:
* retrieve Source from the `resourceManager` with source's named defined
in Tool's config
* validate Source via `compatibleSource interface{}`
* run the remaining `Invoke()` function. Fields that are needed is
retrieved directly from the source.
With this update, resource manager is also added as input to other
Tool's function that require access to source (e.g.
`RequiresClientAuthorization()`).
## Description
---
This pull request adds a new tool, cloud-sql-clone-instance, which
enables cloning a Cloud SQL instance from the toolbox using the Cloud
SQL Admin API. The tool supports both standard cloning and point-in-time
recovery (PITR). It also supports specifying preferred zones for cloned
instances via the preferredZone and preferredSecondaryZone fields.
Key Features:
Instance Cloning: The tool allows you to clone a Cloud SQL instance by
specifying the source and destination instance names.
Point-in-Time Recovery (PITR): By providing a pointInTime timestamp, you
can create a clone of an instance as it existed at a specific moment.
High Availability Configuration: The preferredZone and
preferredSecondaryZone parameters allow you to configure the cloned
instance for high availability.
Tested:
