### MariaDB/MySQL Migration Example Source: https://github.com/ascensiongamedev/intersect-engine/blob/main/Intersect.Server/MIGRATIONS.md An example of the command used to generate a 'Net7Upgrade' migration for a MySQL logging context. This showcases the specific parameters for context name, namespace, output directory, database type, and connection string. ```bash dotnet ef migrations add Net7Upgrade --context MySqlLoggingContext --namespace Intersect.Server.Migrations.MySql.Logging --output-dir Migrations/MySql/Logging/ -- --databaseType MySql --connectionString "Username=;Password=;Database=" ``` -------------------------------- ### SSH Configuration for GitHub Cloning Source: https://github.com/ascensiongamedev/intersect-engine/blob/main/CONTRIBUTING.md An example configuration entry for the `~/.ssh/config` file to enable cloning GitHub repositories using SSH. This setup specifies the host, hostname, user, and the identity file (SSH private key) to be used for authentication. ```shell Host github.com HostName github.com User git IdentityFile ~/.ssh/id_rsa ``` -------------------------------- ### Install dotnet-ef Tool Source: https://github.com/ascensiongamedev/intersect-engine/blob/main/Intersect.Server/MIGRATIONS.md Installs the Entity Framework Core command-line tools globally. This is a prerequisite for managing database migrations. Ensure you use the correct versioning, especially on Unix-like systems where wildcard characters might require escaping. ```bash dotnet tool install --global dotnet-ef --version 7.* ``` ```bash # On Unix-like systems, escape the wildcard if needed: dotnet tool install --global dotnet-ef --version 7.\* ``` -------------------------------- ### Compile Debug Build with Specific Version - .NET CLI Source: https://github.com/ascensiongamedev/intersect-engine/blob/main/README.md This command compiles the Intersect Engine in Debug configuration with specified package and version numbers. Debug builds do not produce single-file binary outputs. It requires the .NET SDK to be installed. ```bash dotnet build -p:Configuration=Debug -p:PackageVersion=0.8.0-beta -p:Version=0.8.0 ``` -------------------------------- ### MariaDB/MySQL Connection Error Example Source: https://github.com/ascensiongamedev/intersect-engine/blob/main/Intersect.Server/MIGRATIONS.md Illustrates a typical error message when a MariaDB/MySQL migration fails due to an invalid or missing connection string. The error indicates an inability to create the DbContext, often stemming from authentication issues. ```bash Unable to create a 'DbContext' of type 'MySqlGameContext'. For the different patterns supported at design time, see https://go.microsoft.com/fwlink/?linkid=851728 ``` -------------------------------- ### Compile Release Build with Specific Version - .NET CLI Source: https://github.com/ascensiongamedev/intersect-engine/blob/main/README.md This command compiles the Intersect Engine in Release configuration with specified package and version numbers. Release builds create single-file binary outputs; for a cleaner output, 'dotnet publish' is recommended. Requires the .NET SDK. ```bash dotnet build -p:Configuration=Release -p:PackageVersion=0.8.0-beta -p:Version=0.8.0 ``` -------------------------------- ### Generate Database Migration Source: https://github.com/ascensiongamedev/intersect-engine/blob/main/Intersect.Server/MIGRATIONS.md Generates a new database migration using the Entity Framework Core CLI. It's crucial to include the `--namespace` and `--output-dir` parameters to ensure correct generation of snapshot files. The command supports specifying the database provider and optionally a connection string. ```bash # General command pattern: dotnet ef migrations add --context --namespace Intersect.Server.Migrations.. --output-dir Migrations/// -- --databaseType [--connectionString "..."] ``` -------------------------------- ### Publish Release Build for Specific Runtime ID - .NET CLI Source: https://github.com/ascensiongamedev/intersect-engine/blob/main/README.md This command publishes the Intersect Engine in Release configuration for a specific runtime identifier (RID), creating a self-contained, single-file binary output. It requires the .NET SDK and the correct RID for the target platform. This is the method used by the automated builds. ```bash dotnet publish -p:Configuration=Release -p:PackageVersion=0.8.0-beta -p:Version=0.8.0 -r ``` ```bash # Example for Linux x64: dotnet publish -p:Configuration=Release -p:PackageVersion=0.8.0-beta -p:Version=0.8.0 -r linux-x64 ``` -------------------------------- ### Generate MariaDB/MySQL Migration Command Source: https://github.com/ascensiongamedev/intersect-engine/blob/main/Intersect.Server/MIGRATIONS.md This command-line instruction generates a new database migration for MariaDB or MySQL. It requires a migration name, context details, namespace, output directory, and a valid connection string. The `--databaseType` parameter should always be 'MySql' when working with either MariaDB or MySQL. ```bash dotnet ef migrations add --context MySql --namespace Intersect.Server.Migrations.MySql. --output-dir Migrations/MySql// -- --databaseType MySql --connectionString "..." ``` -------------------------------- ### Update dotnet-ef Tool Source: https://github.com/ascensiongamedev/intersect-engine/blob/main/Intersect.Server/MIGRATIONS.md Updates the Entity Framework Core command-line tools to a specific version or the latest available. This is useful for resolving version warnings and obtaining the latest features and bug fixes. Wildcard escaping may be necessary on Unix-like systems. ```bash # Update to a specific version: dotnet tool update --global dotnet-ef --version 7.0.13 ``` ```bash # Update to the latest minor version within a major release (escape wildcard on Unix-like systems): dotnet tool update --global dotnet-ef --version 7.* ``` ```bash # On Unix-like systems, escape the wildcard if needed: dotnet tool update --global dotnet-ef --version 7.\* ``` -------------------------------- ### Full Stacktrace for MariaDB/MySQL Connection Failure Source: https://github.com/ascensiongamedev/intersect-engine/blob/main/Intersect.Server/MIGRATIONS.md A detailed stack trace indicating a 'MySqlException' with an 'Access denied' error, commonly encountered when the connection string is missing or incorrect, preventing the DbContext from being instantiated. ```csharp Microsoft.EntityFrameworkCore.Design.OperationException: Unable to create an object of type 'MySqlPlayerContext'.
