From f68efeeb45702d46cfb52d5e0a35f409febdcfe1 Mon Sep 17 00:00:00 2001 From: 0xasun Date: Mon, 21 Jul 2025 16:09:48 -0600 Subject: [PATCH] feat: add comprehensive backup functionality for vault operations Summary of Changes: - Added backup prompts when saving/modifying vault files (default: Yes) - Added backup prompt for GPG encryption (default: Yes) - ASCII armor prompt now defaults to Yes - Improved backup file naming to preserve extensions - Added overwrite protection for existing files Detailed Changes: 1. Vault Backup System (service.rs): - Added create_backup() method that creates timestamped backups - Integrated backup prompt in save_vault() with Y default - Backup format: vault.toml.backup.{timestamp} 2. GPG Improvements (gpg.rs): - Updated encrypt_vault() to handle .toml.gpg/.toml.asc extensions - Added overwrite prompts for existing GPG files - Improved backup_vault() to create .gpg.backup format for GPG files - Fixed extension handling in decrypt_vault() 3. User Prompts (utils.rs): - Added prompt_yes_no() utility for consistent Y/n prompting - Used throughout for backup and overwrite confirmations 4. CLI Updates (cli.rs): - Updated gpg_encrypt to use prompt_yes_no with Y default - Removed redundant backup code (now handled by GPG module) 5. Interactive Mode (interactive.rs): - Changed ASCII armor prompt to Y default - Changed backup prompt to Y default - Used prompt_yes_no for consistency File Naming Conventions: - Regular backups: vault.toml.backup.20250721_152607 - GPG backups: vault.toml.gpg.backup.20250721_152607 - GPG encrypted: vault.toml.gpg (binary) or vault.toml.asc (ASCII) All changes maintain backward compatibility while improving user safety through better backup defaults and overwrite protection. --- src/cli.rs | 6 +--- src/gpg.rs | 77 +++++++++++++++++++++++++++++++++++++--------- src/interactive.rs | 14 ++------- src/service.rs | 35 +++++++++++++++++++++ src/utils.rs | 19 ++++++++++++ 5 files changed, 119 insertions(+), 32 deletions(-) diff --git a/src/cli.rs b/src/cli.rs index b7ab472..46cf1ed 100644 --- a/src/cli.rs +++ b/src/cli.rs @@ -537,11 +537,7 @@ impl Cli { let should_backup = if backup { true } else { - print!("Create backup before encryption?
