# HeroDB Model Creation Instructions for AI

## Overview

This document provides clear instructions for AI agents to create new HeroDB models similar to `comment.v`. These models are used to store structured data in Redis using the HeroDB system.

## Key Concepts

- Each model represents a data type stored in Redis hash sets
- Models must implement serialization/deserialization using the `encoder` module
- Models inherit from the `Base` struct which provides common fields
- The database uses a factory pattern for model access

## File Structure

Create a new file in `lib/hero/heromodels/` with the model name (e.g., `calendar.v`).

## Required Components

### 1. Model Struct Definition

Define your model struct with the following pattern:

```v
@[heap]
pub struct Calendar {
 db.Base // Inherit from Base struct
pub mut:
 // Add your specific fields here
 title       string
 start_time  i64
 end_time    i64
 location    string
 attendees   []string
}

2. Type Name Method

Implement a method to return the model's type name:

pub fn (self Calendar) type_name() string {
 return 'calendar'
}

3. Serialization (dump) Method

Implement the dump method to serialize your struct's fields using the encoder:

pub fn (self Calendar) dump(mut e &encoder.Encoder) ! {
 e.add_string(self.title)
 e.add_i64(self.start_time)
 e.add_i64(self.end_time)
 e.add_string(self.location)
 e.add_list_string(self.attendees)
}

4. Deserialization (load) Method

Implement the load method to deserialize your struct's fields:

fn (mut self DBCalendar) load(mut o Calendar, mut e &encoder.Decoder) ! {
 o.title = e.get_string()!
 o.start_time = e.get_i64()!
 o.end_time = e.get_i64()!
 o.location = e.get_string()!
 o.attendees = e.get_list_string()!
}

5. Model Arguments Struct

Define a struct for creating new instances of your model:

@[params]
pub struct CalendarArg {
pub mut:
 title      string @[required]
 start_time i64
 end_time   i64
 location   string
 attendees  []string
}

6. Database Wrapper Struct

Create a database wrapper struct for your model:

pub struct DBCalendar {
pub mut:
 db &db.DB @[skip; str: skip]
}

7. Factory Integration

Add your model to the ModelsFactory struct in factory.v:

pub struct ModelsFactory {
pub mut:
 comments DBCalendar
 // ... other models
}

And initialize it in the new() function:

pub fn new() !ModelsFactory {
 mut mydb := db.new()!
 return ModelsFactory{
  comments: DBCalendar{
   db: &mydb
  }
  // ... initialize other models
 }
}

Encoder Methods Reference

Use these methods for serialization/deserialization:

Encoder (Serialization)

  • e.add_bool(val bool)
  • e.add_u8(val u8)
  • e.add_u16(val u16)
  • e.add_u32(val u32)
  • e.add_u64(val u64)
  • e.add_i8(val i8)
  • e.add_i16(val i16)
  • e.add_i32(val i32)
  • e.add_i64(val i64)
  • e.add_f32(val f32)
  • e.add_f64(val f64)
  • e.add_string(val string)
  • e.add_list_bool(val []bool)
  • e.add_list_u8(val []u8)
  • e.add_list_u16(val []u16)
  • e.add_list_u32(val []u32)
  • e.add_list_u64(val []u64)
  • e.add_list_i8(val []i8)
  • e.add_list_i16(val []i16)
  • e.add_list_i32(val []i32)
  • e.add_list_i64(val []i64)
  • e.add_list_f32(val []f32)
  • e.add_list_f64(val []f64)
  • e.add_list_string(val []string)

Decoder (Deserialization)

  • e.get_bool()!
  • e.get_u8()!
  • e.get_u16()!
  • e.get_u32()!
  • e.get_u64()!
  • e.get_i8()!
  • e.get_i16()!
  • e.get_i32()!
  • e.get_i64()!
  • e.get_f32()!
  • e.get_f64()!

CRUD Methods Implementation

Create New Instance

pub fn (mut self DBCalendar) new(args CalendarArg) !Calendar {
 mut o := Calendar{
  title:      args.title
  start_time: args.start_time
  end_time:   args.end_time
  location:   args.location
  attendees:  args.attendees
  updated_at: ourtime.now().unix()
 }
 return o
}

Save to Database

pub fn (mut self DBCalendar) set(o Calendar) !u32 {
 return self.db.set[Calendar](o)!
}

Retrieve from Database

pub fn (mut self DBCalendar) get(id u32) !Calendar {
 mut o, data := self.db.get_data[Calendar](id)!
 mut e_decoder := encoder.decoder_new(data)
 self.load(mut o, mut e_decoder)!
 return o
}

Delete from Database

pub fn (mut self DBCalendar) delete(id u32) ! {
 self.db.delete[Calendar](id)!
}

Check Existence

pub fn (mut self DBCalendar) exist(id u32) !bool {
 return self.db.exists[Calendar](id)!
}

List All Objects

pub fn (mut self DBCalendar) list() ![]Calendar {
 return self.db.list[Calendar]()!.map(self.get(it)!)
}

Example Usage Script

Create a .vsh script in examples/hero/heromodels/ to demonstrate usage:

#!/usr/bin/env -S v -n -w -cg -gc none -cc tcc -d use_openssl -enable-globals run

import incubaid.herolib.core.redisclient
import incubaid.herolib.hero.heromodels

mut mydb := heromodels.new()!

// Create a new object
mut o := mydb.calendar.new(
 title: 'Meeting'
 start_time: 1672531200
 end_time: 1672534800
 location: 'Conference Room'
 attendees: ['john@example.com', 'jane@example.com']
)!

// Save to database
oid := mydb.calendar.set(o)!
println('Created object with ID: ${oid}')

// Retrieve from database
mut o2 := mydb.calendar.get(oid)!
println('Retrieved object: ${o2}')

// List all objects
mut objects := mydb.calendar.list()!
println('All objects: ${objects}')

Best Practices

  1. Always inherit from db.Base struct
  2. Implement all required methods (type_name, dump, load)
  3. Use the encoder methods for consistent serialization
  4. Handle errors appropriately with ! or or blocks
  5. Keep field ordering consistent between dump and load methods
  6. Use snake_case for field names
  7. Add @[required] attribute to mandatory fields in argument structs
  8. Initialize timestamps using ourtime.now().unix()

Implementation Steps Summary

  1. Create model struct inheriting from db.Base
  2. Implement type_name() method
  3. Implement dump() method using encoder
  4. Implement load() method using decoder
  5. Create argument struct with @[params] attribute
  6. Create database wrapper struct
  7. Add model to ModelsFactory in factory.v
  8. Implement CRUD methods
  9. Create example usage script
  10. Test the implementation with the example script

# HeroFS - Distributed Filesystem for HeroLib

HeroFS is a distributed filesystem implementation built on top of HeroDB (Redis-based storage). It provides a virtual filesystem with support for files, directories, symbolic links, and binary data blobs.

## Overview

HeroFS implements a filesystem structure where:
- **Fs**: Represents a filesystem as a top-level container
- **FsDir**: Represents directories within a filesystem
- **FsFile**: Represents files with support for multiple directory associations
- **FsSymlink**: Represents symbolic links pointing to files or directories
- **FsBlob**: Represents binary data chunks (up to 1MB) used as file content

## Features

- Distributed storage using Redis
- Support for files, directories, and symbolic links
- Blob-based file content storage with integrity verification
- Multiple directory associations for files (similar to hard links)
- Filesystem quotas and usage tracking
- Metadata support for files
- Efficient lookup mechanisms using Redis hash sets

## Installation

HeroFS is part of HeroLib and is automatically available when using HeroLib.

## Usage

To use HeroFS, you need to create a filesystem factory:

```v
import incubaid.herolib.hero.herofs

mut fs_factory := herofs.new()!

Creating a Filesystem

fs_id := fs_factory.fs.set(fs_factory.fs.new(
 name: 'my_filesystem'
 quota_bytes: 1000000000 // 1GB quota
)!)!

Working with Directories

// Create root directory
root_dir_id := fs_factory.fs_dir.set(fs_factory.fs_dir.new(
 name: 'root'
 fs_id: fs_id
 parent_id: 0
)!)!

// Create subdirectory
sub_dir_id := fs_factory.fs_dir.set(fs_factory.fs_dir.new(
 name: 'documents'
 fs_id: fs_id
 parent_id: root_dir_id
)!)!

Working with Blobs

// Create a blob with binary data
blob_id := fs_factory.fs_blob.set(fs_factory.fs_blob.new(
 data: content_bytes
 mime_type: 'text/plain'
)!)!

Working with Files

// Create a file
file_id := fs_factory.fs_file.set(fs_factory.fs_file.new(
 name: 'example.txt'
 fs_id: fs_id
 directories: [root_dir_id]
 blobs: [blob_id]
)!)!
// Create a symbolic link to a file
symlink_id := fs_factory.fs_symlink.set(fs_factory.fs_symlink.new(
 name: 'example_link.txt'
 fs_id: fs_id
 parent_id: root_dir_id
 target_id: file_id
 target_type: .file
)!)!

# HeroFS Specifications

This document provides detailed specifications for the HeroFS distributed filesystem implementation.

## Architecture Overview

HeroFS is built on top of HeroDB, which uses Redis as its storage backend. The filesystem is implemented as a collection of interconnected data structures that represent the various components of a filesystem:

1. **Fs** - Filesystem container
2. **FsDir** - Directories
3. **FsFile** - Files
4. **FsSymlink** - Symbolic links
5. **FsBlob** - Binary data chunks

All components inherit from the `Base` struct, which provides common fields like ID, name, description, timestamps, security policies, tags, and comments.

## Filesystem (Fs)

The `Fs` struct represents a filesystem as a top-level container:

```v
@[heap]
pub struct Fs {
 db.Base
pub mut:
 name        string
 group_id    u32 // Associated group for permissions
 root_dir_id u32 // ID of root directory
 quota_bytes u64 // Storage quota in bytes
 used_bytes  u64 // Current usage in bytes
}

Key Features

  • Name-based identification: Filesystems can be retrieved by name using efficient Redis hash sets
  • Quota management: Each filesystem has a storage quota and tracks current usage
  • Root directory: Each filesystem has a root directory ID that serves as the entry point
  • Group association: Filesystems can be associated with groups for permission management

Methods

  • new(): Create a new filesystem instance
  • set(): Save filesystem to database
  • get(): Retrieve filesystem by ID
  • get_by_name(): Retrieve filesystem by name
  • delete(): Remove filesystem from database
  • exist(): Check if filesystem exists
  • list(): List all filesystems
  • increase_usage(): Increase used bytes counter
  • decrease_usage(): Decrease used bytes counter
  • check_quota(): Verify if additional bytes would exceed quota

Directory (FsDir)

The FsDir struct represents a directory in a filesystem:

@[heap]
pub struct FsDir {
 db.Base
pub mut:
 name       string
 fs_id      u32   // Associated filesystem
 parent_id  u32   // Parent directory ID (0 for root)
}

Key Features

  • Hierarchical structure: Directories form a tree structure with parent-child relationships
  • Path-based identification: Efficient lookup by filesystem ID, parent ID, and name
  • Children management: Directories automatically track their children through Redis hash sets
  • Cross-filesystem isolation: Directories are bound to a specific filesystem

Methods

  • new(): Create a new directory instance
  • set(): Save directory to database and update indices
  • get(): Retrieve directory by ID
  • delete(): Remove directory (fails if it has children)
  • exist(): Check if directory exists
  • list(): List all directories
  • get_by_path(): Retrieve directory by path components
  • list_by_filesystem(): List directories in a filesystem
  • list_children(): List child directories
  • has_children(): Check if directory has children
  • rename(): Rename directory
  • move(): Move directory to a new parent

File (FsFile)

The FsFile struct represents a file in a filesystem:

@[heap]
pub struct FsFile {
 db.Base
pub mut:
 name        string
 fs_id       u32     // Associated filesystem
 directories []u32   // Directory IDs where this file exists
 blobs       []u32   // IDs of file content blobs
 size_bytes  u64    
 mime_type   string  // e.g., "image/png"
 checksum    string  // e.g., SHA256 checksum of the file
 accessed_at i64
 metadata    map[string]string // Custom metadata
}

Key Features

  • Multiple directory associations: Files can exist in multiple directories (similar to hard links in Linux)
  • Blob-based content: File content is stored as references to FsBlob objects
  • Size tracking: Files track their total size in bytes
  • MIME type support: Files store their MIME type for content identification
  • Checksum verification: Files can store checksums for integrity verification
  • Access timestamp: Tracks when the file was last accessed
  • Custom metadata: Files support custom key-value metadata

Methods

  • new(): Create a new file instance
  • set(): Save file to database and update indices
  • get(): Retrieve file by ID
  • delete(): Remove file and update all indices
  • exist(): Check if file exists
  • list(): List all files
  • get_by_path(): Retrieve file by directory and name
  • list_by_directory(): List files in a directory
  • list_by_filesystem(): List files in a filesystem
  • list_by_mime_type(): List files by MIME type
  • append_blob(): Add a new blob to the file
  • update_accessed(): Update accessed timestamp
  • update_metadata(): Update file metadata
  • rename(): Rename file (affects all directories)
  • move(): Move file to different directories

The FsSymlink struct represents a symbolic link in a filesystem:

@[heap]
pub struct FsSymlink {
 db.Base
pub mut:
 name        string
 fs_id       u32 // Associated filesystem
 parent_id   u32 // Parent directory ID
 target_id   u32 // ID of target file or directory
 target_type SymlinkTargetType
}

pub enum SymlinkTargetType {
 file
 directory
}

Key Features

  • Target type specification: Symlinks can point to either files or directories
  • Cross-filesystem protection: Symlinks cannot point to targets in different filesystems
  • Referrer tracking: Targets know which symlinks point to them
  • Broken link detection: Symlinks can be checked for validity

Methods

  • new(): Create a new symbolic link instance
  • set(): Save symlink to database and update indices
  • get(): Retrieve symlink by ID
  • delete(): Remove symlink and update all indices
  • exist(): Check if symlink exists
  • list(): List all symlinks
  • get_by_path(): Retrieve symlink by parent directory and name
  • list_by_parent(): List symlinks in a parent directory
  • list_by_filesystem(): List symlinks in a filesystem
  • list_by_target(): List symlinks pointing to a target
  • rename(): Rename symlink
  • move(): Move symlink to a new parent directory
  • redirect(): Change symlink target
  • resolve(): Get the target ID of a symlink
  • is_broken(): Check if symlink target exists

Binary Data Blob (FsBlob)

The FsBlob struct represents binary data chunks:

@[heap]
pub struct FsBlob {
 db.Base
pub mut:
 hash        string // blake192 hash of content
 data        []u8   // Binary data (max 1MB)
 size_bytes  int    // Size in bytes
 created_at  i64
 mime_type   string // MIME type
 encoding    string // Encoding type
}

Key Features

  • Content-based addressing: Blobs are identified by their BLAKE3 hash (first 192 bits)
  • Size limit: Blobs are limited to 1MB to ensure efficient storage and retrieval
  • Integrity verification: Built-in hash verification for data integrity
  • MIME type and encoding: Blobs store their content type information
  • Deduplication: Identical content blobs are automatically deduplicated

Methods

  • new(): Create a new blob instance
  • set(): Save blob to database (returns existing ID if content already exists)
  • get(): Retrieve blob by ID
  • delete(): Remove blob from database
  • exist(): Check if blob exists
  • list(): List all blobs
  • get_by_hash(): Retrieve blob by content hash
  • exists_by_hash(): Check if blob exists by content hash
  • verify_integrity(): Verify blob data integrity against stored hash
  • calculate_hash(): Calculate BLAKE3 hash of blob data

Storage Mechanisms

HeroFS uses Redis hash sets extensively for efficient indexing and lookup:

Filesystem Indices

  • fs:names - Maps filesystem names to IDs
  • fsdir:paths - Maps directory path components to IDs
  • fsdir:fs:${fs_id} - Lists directories in a filesystem
  • fsdir:children:${dir_id} - Lists children of a directory
  • fsfile:paths - Maps file paths (directory:name) to IDs
  • fsfile:dir:${dir_id} - Lists files in a directory
  • fsfile:fs:${fs_id} - Lists files in a filesystem
  • fsfile:mime:${mime_type} - Lists files by MIME type
  • fssymlink:paths - Maps symlink paths (parent:name) to IDs
  • fssymlink:parent:${parent_id} - Lists symlinks in a parent directory
  • fssymlink:fs:${fs_id} - Lists symlinks in a filesystem
  • fssymlink:target:${target_type}:${target_id} - Lists symlinks pointing to a target
  • fsblob:hashes - Maps content hashes to blob IDs

Data Serialization

All HeroFS components use the HeroLib encoder for serialization:

  • Version tag (u8) is stored first
  • All fields are serialized in a consistent order
  • Deserialization follows the exact same order
  • Type safety is maintained through V's type system

Special Features

Files can be associated with multiple directories through the directories field, allowing for hard link-like behavior.

Deduplication

Blobs are automatically deduplicated based on their content hash. When creating a new blob with identical content to an existing one, the existing ID is returned.

Quota Management

Filesystems track their storage usage and can enforce quotas to prevent overconsumption.

Metadata Support

Files support custom metadata as key-value pairs, allowing for flexible attribute storage.

Cross-Component Validation

When creating or modifying components, HeroFS validates references to other components:

  • Directory parent must exist
  • File directories must exist
  • File blobs must exist
  • Symlink parent must exist
  • Symlink target must exist and match target type

Security Model

HeroFS inherits the security model from HeroDB:

  • Each component has a securitypolicy field referencing a SecurityPolicy object
  • Components can have associated tags for categorization
  • Components can have associated comments for documentation

Performance Considerations

  • All indices are stored as Redis hash sets for O(1) lookup performance
  • Blob deduplication reduces storage requirements
  • Multiple directory associations allow efficient file organization
  • Content-based addressing enables easy integrity verification
  • Factory pattern provides easy access to all filesystem components

for lib/hero/herofs

we need to do some refactoring

- we should create a fs_tools.v and this has functions more high level to walk over the filesystem like you would expect from an fs and other tools
- find with include/exclude starting from a path, returning []FindResult and FindResult has 2 props: .enum for file,dir or link, and the u32 id to the obj
    - can be recursive and not
- a cp, rm, move all starting from path


basically make it easy to manipulate the fs

when doing a rm, we need to say if we have flag to say if we want to delete the blobs or not, default not

make clear steps and then do them one by one

report well on what you are doing
