sshmirror 0.1.16

SSH directory synchronization library and CLI

SSHMirror

Sync a working directory with a remote server over SSH, inspect diffs before applying changes, and keep a lightweight local history for rollback-oriented workflows.

SSHMirror is both:

• a Python library you can import;
• a CLI you can run inside a project folder;
• a sync workflow that keeps local and remote changes inspectable.

It can also be used as a lightweight sync workflow for a shared project: multiple developers can make changes to the same remote-backed codebase and inspect differences before pulling or pushing updates.

Internet access is not required for SSHMirror itself. It only needs network access to the target SSH host or Docker host you are synchronizing with.

When you run sshmirror without arguments, it opens an interactive menu. Depending on project state, the menu can include:

• Create sshmirror.config.yml
• Create sshmirror.ignore.txt
• Initialization
• Pull & Push
• Status
• View current changes
• Versions (History, Compare)
• Pull only
• Stash changes
• Restore stashed changes
• Discard all local changes
• Discard selected files
• Downgrade remote version
• Test connection
• Exit

Why It Stands Out

• Preview first. Inspect current file changes and version-to-version diffs before syncing. 🔍
• Built for real SSH workflows. Passwords, SSH keys, passphrases, and ssh-agent fallback are supported. 🔐
• Keeps local state. SSHMirror stores version and migration metadata under .sshmirror/. 🗂️
• Works as a library or a command-line tool. 🐍
• Useful for team workflows. Several developers can work on one project and sync changes through the same remote environment. 🤝
• Optional remote container restart after sync. 🐳

Install 🚀

pip install sshmirror

For local development:

pip install -e .

Quick Start ⚡

1. Create a config file:

   sshmirror
   

   On first interactive launch, SSHMirror can create sshmirror.config.yml for you.

2. Start from this minimal config:

   host: '192.168.12.22'
   port: '50022'
   username: 'root'
   localdir: '.'
   remotedir: '/app'
   author: your-name
   

3. Check status or connect-test before syncing:

   sshmirror --status
   sshmirror --test-connection
   

Example Configuration ⚙️

The full example lives in sshmirror.config.example.yml.

Supported auth patterns:

• password auth;
• private key auth;
• private key with passphrase;
• default SSH keys or ssh-agent when no key and no password are provided.

Example with optional container restart:

host: '192.168.12.22'
port: '50022'
username: 'root'
localdir: '.'
remotedir: '/app'
author: your-name

restart_container:
   # Optional. If omitted, host/port/username are reused from the main SSH config.
   # host: '192.168.12.22'
   # port: '23322'
   # username: user
  sudo: true
  container_name: testcontainer

restart_container connects to the Docker host where the container is running. If host, port, or username are not specified there, SSHMirror uses the main connection values.

CLI Commands 🧰

sshmirror --help

Main non-interactive flags:

• --status show local and remote sync status;
• --current-diff inspect current local versus remote differences;
• --version-diff inspect changes between remote versions;
• --pull only pull from remote;
• --stash-changes stash local changes before syncing;
• --restore-stash restore previously stashed changes;
• --discard discard all local changes;
• --discard-files <paths...> discard only selected files;
• --downgrade downgrade remote version;
• --test-connection validate SSH access to the remote host and configured Docker host.

Library Usage 📦

from sshmirror import SSHMirror, SSHMirrorConfig

mirror = SSHMirror(
    config=SSHMirrorConfig(
        host='127.0.0.1',
        port=22,
        username='root',
        localdir='.',
        remotedir='/app',
    )
)

The public API is exported from sshmirror/init.py.

Status

This repository is structured as a Python package with a CLI entry point. If you plan to publish to PyPI, keep package metadata, README, and license in sync with actual behavior.

Changelog

0.1.16

Changed

• Replaced the interactive View version changes menu item with a Versions submenu containing History and Compare.
• Added automatic previous-version diff browsing for Versions -> History.
• Reworked push and pull execution so the existing preview table stays on screen and the Status column updates live during synchronization.
• Made version descriptions mandatory during push instead of silently defaulting to update.

Fixed

• Removed duplicate visible CLI actions for force-discarding local changes, leaving a single user-facing discard action.
• Skipped the expensive full project re-compare after a normal push when no sync hook commands are configured.
• Cleared the temporary Connect to remote... line before interactive version lists are shown.
• Adjusted version pagination controls so Older versions appears before the version list and Newer versions appears after it.
• Made remote push synchronization atomic by rolling back remote changes when any file sync step fails.
• Switched generated downgrade scripts to relative paths so rollback metadata no longer embeds absolute remote project paths.

0.1.15

Changed

• Improved interactive version history rendering with fixed-width columns for version number, timestamp, author, uid, and message.
• Improved file change browsing so changed, created, and deleted entries are shown together with clearer color-coded styling.
• Improved push and pull previews with structured summary panels and color-coded action tables before confirmation.

0.1.14

Changed

• Highlighted the selected base version during target version selection so the comparison source stays visible in interactive history browsing.

Fixed

• Removed duplicated version history rendering so interactive diff browsing shows a single styled selection list instead of both a table and a separate prompt list.

0.1.13

Fixed

• Fixed interactive questionary prompts inside async CLI flows so they no longer fail with asyncio.run() cannot be called from a running event loop.
• Fixed version and diff browsing prompts to run safely while the CLI event loop is active.

0.1.12

Fixed

• Fixed Ctrl+C handling in interactive menus so cancellation exits cleanly instead of falling back to plain input.
• Fixed prompt cancellation handling for both questionary prompts and plain-input fallback paths.

0.1.11

Changed

• Finalized interactive diff browsing so version pages open with the newest item on the current page selected by default.
• Restricted textual diff inspection to inspectable changed files only.

Fixed

• Prevented oversized changed files from being selectable in interactive diff views.

0.1.10

Changed

• Reworked View version changes for large version histories.
• Replaced full-history rendering with interactive paginated browsing.
• Improved version timestamp presentation in interactive history views.
• Added colored tabular rendering and numeric shortcuts for version selection.

Added

• Added lazy remote paging for interactive version history browsing.
• Added author display in interactive version history views.
• Added a 50-character validation limit for version descriptions.

0.1.9

Fixed

• Fixed sudo password authentication for restart_container.

Added

• Added step-by-step Docker host diagnostics for Docker host checks.

0.1.8

Fixed

• Fixed restart_container connection handling.

Changed

• Removed deprecated restart_container.user support and standardized on restart_container.username.

Added

• Added startup validation for the full configuration, including restart_container consistency checks.

0.1.7

Changed

• Optimized local and remote scanning so ignored directories are pruned instead of scanned and filtered after traversal.

0.1.6

Fixed

• Fixed postponed annotation evaluation and runtime annotation handling.
