Feature: Remote Operations (clone, fetch, pull, push)

[BishopMowle]

Overview

Implement remote operations to enable ts-git to interact with remote repositories, matching isomorphic-git feature parity.

Commands to Implement

• clone - Clone a repository from a remote URL
• fetch - Fetch commits from a remote repository
• pull - Fetch and merge commits from a remote
• push - Push commits to a remote repository
• addRemote - Add a new remote repository
• deleteRemote - Remove a remote repository
• getRemoteInfo - Get information about a remote
• listRemotes - List all configured remotes

Acceptance Criteria (AC)

1. AC1: Clone Functionality - Can clone a public repository from GitHub/Bitbucket via HTTPS
2. AC2: Fetch Functionality - Can fetch refs and objects from a remote without merging
3. AC3: Push Functionality - Can push local commits to a remote (with auth support for HTTPS)
4. AC4: Remote Management - Can add, list, and delete remote configurations
5. AC5: Pull Integration - Pull correctly fetches and merges/fast-forwards changes
6. AC6: Type Safety - All functions have strict TypeScript types for parameters and return values

Definition of Done (DoD)

• All commands implemented with error handling
• Unit tests with >80% coverage
• Interop tests passing (see below)
• Documentation in README.md
• No TypeScript errors or warnings

Interop Test Method

Create interoperability tests that compare ts-git output with canonical git CLI:

// Test clone
await tsGit.clone({ fs, http, dir: '/tmp/test-clone', url: 'https://github.com/octocat/Hello-World.git', depth: 1 });
const tsGitLog = await tsGit.log({ fs, dir: '/tmp/test-clone', depth: 1 });

// Compare with canonical git
execSync('git clone --depth 1 https://github.com/octocat/Hello-World.git /tmp/ref-clone');
const refLog = execSync('git -C /tmp/ref-clone log --oneline -1').toString();

// Assertions: tsGitLog[0].oid should match ref commit hash

Validation Strategy:

1. Clone same repo with ts-git and canonical git
2. Compare commit hashes, tree structure, and file contents
3. Push to test remote and verify with canonical git
4. Test error cases: auth failures, 404s, network errors

Priority

High - Core functionality for distributed version control

Dependencies

• Requires HTTP client abstraction (HttpClient interface)
• May require authentication token support

Issue #5: Remote Operations - AC/DoD

Acceptance Criteria (AC)

AC1: Clone Functionality

• Can clone a public repository from GitHub/Bitbucket via HTTPS
• Returns proper repository structure after clone

AC2: Fetch Functionality

• Can fetch refs and objects from a remote without merging
• Updates remote tracking branches correctly

AC3: Push Functionality

• Can push local commits to a remote (with auth support for HTTPS)
• Handles authentication properly

AC4: Remote Management

• Can add, list, and delete remote configurations
• Remote configs persist correctly

AC5: Pull Integration

• Pull correctly fetches and merges/fast-forwards changes
• Handles conflicts appropriately

AC6: Type Safety

• All functions have strict TypeScript types
• No any or unknown types in parameters/returns

Definition of Done (DoD)

• All commands implemented with error handling
• Unit tests with >80% coverage
• Interop tests passing (comparing with canonical git CLI output)
• Documentation in README.md
• Zero TypeScript errors/warnings

Waiting for Edwards approval before implementation begins

AC/DoD APPROVED

Edward has approved the AC/DoD for Issue #5: Remote Operations.

Implementation may begin.

Requirements:

• Implement all commands with strict TypeScript
• Write interop tests comparing to canonical git CLI
• Update documentation in README.md
• Zero TypeScript errors

Code Review: Issue #5 Implementation

Summary

The implementation for Remote Operations has been reviewed. All core functionality has been implemented and tested.

---

1. TypeScript Compilation

Status: PASS

The TypeScript build completes without errors:

cd packages/ts-git && pnpm build
> @keydown-app/ts-git@0.1.0 build
> tsc

---

2. Code Quality & Patterns

Status: PASS

• Type Safety: No any or unknown type declarations found in new code. All functions use explicit TypeScript interfaces.
• Error Handling: Proper error types used (NotFoundError, NotAGitRepoError, AlreadyExistsError)
• Code Organization: Clean separation between:
  • commands/remote.ts - Remote management functions
  • commands/clone.ts - Clone/fetch/push/pull functions
  • client/index.ts - GitClient API methods
  • types.ts - Type definitions for interfaces
• API Consistency: GitClient methods follow existing patterns (directory checks, error handling)

---

3. Interop Tests

Status: PASS

All remote-related interop tests pass:

Test File	Tests	Status
remote-interop.test.ts	4	All pass
clone-interop.test.ts	7	All pass
remote.test.ts	12	All pass
clone-commands.test.ts	7	All pass

Total: 30 tests passing

---

4. Documentation

Status: PASS

README.md updated with:

• Supported commands table (clone, fetch, pull, push, remote)
• "Remote Operations" section with code examples
• CLI command examples for remote operations

---

5. Pre-existing Test Failures

Note: 4 test files fail due to module resolution issues, but these are NOT related to Issue #5:

• cat-file.test.ts - Cannot find module ../cat-file.js
• hash-object.test.ts - Cannot find module ../hash-object.js
• ls-tree.test.ts - Cannot find module ../ls-tree.js
• update-index.test.ts - Cannot find module ../update-index.js

These tests import from incorrect relative paths (../ instead of ../../commands/) and are pre-existing issues.

---

What Was Implemented

Commands (remote operations):

• remote add <name> <url> - Add a new remote
• remote -v - List remotes with URLs
• remote remove <name> - Delete a remote
• clone <url> - Clone a repository
• fetch [remote] - Fetch from remote
• pull [remote] - Pull and merge
• push [remote] [refspec] - Push to remote

GitClient API methods:

• addRemote(name, url)
• listRemotes(verbose)
• removeRemote(name)
• clone(url, options?)
• fetch(options?)
• push(options?)
• pull(options?)

---

Recommendation

READY FOR MERGE

The implementation meets all acceptance criteria:

1. Clone functionality working
2. Fetch functionality working
3. Push functionality working
4. Remote management (add/list/delete) working
5. Pull integration working
6. Strict TypeScript types throughout

All new tests pass. The pre-existing test failures are unrelated to this issue and should be addressedseparately.
