From 6d11093152fbe8067c9bfdfa1494bc5679c63c38 Mon Sep 17 00:00:00 2001 From: Lakr Date: Tue, 10 Mar 2026 14:34:18 +0800 Subject: [PATCH] feat: Add VM manifest system and code clarity improvements MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement VM configuration manifest system compatible with security-pcc's VMBundle.Config format, storing VM settings in config.plist. **Manifest System:** - Add VPhoneVirtualMachineManifest.swift with security-pcc compatible structure - Add scripts/vm_manifest.py for manifest generation during vm_new - Update VPhoneCLI to support --config option with CLI overrides - Update vm_create.sh to generate config.plist with CPU/memory/screen settings **Environment Variables:** - CPU/MEMORY/DISK_SIZE now only used during vm_new (written to manifest) - boot/boot_dfu automatically read from config.plist - Remove unused CFW_INPUT variable (overridden by scripts internally) - Document remaining variables with their usage scope **Documentation:** - Update README.md with VM configuration section - Update docs/README_{zh,ja,ko}.md with translated VM configuration docs - Update Makefile help output with vm_new options and config.plist usage - Fix fw_patch_jb description: "dev + JB extensions" - Fix restore_get_shsh description: "Dump SHSH response from Apple" **Code Quality:** - Add VPhoneVirtualMachineRefactored.swift demonstrating code-clarity principles - Extract 200+ line init into focused configuration methods - Improve naming: hardwareModel, graphicsConfiguration, soundDevice - Add BatteryConnectivity enum for magic numbers - Create research/manifest_and_refactoring_summary.md with full analysis **Compatibility with security-pcc:** - Platform type: Fixed vresearch101 (iPhone-only) - Network: NAT only (no bridging/host-only needed) - Added: ScreenConfig and SEP storage (iPhone-specific) - Removed: VirtMesh plugin support (PCC-specific) docs: add machineIdentifier storage analysis Research and validate the integration of machineIdentifier into config.plist. **Findings:** - security-pcc stores machineIdentifier in config.plist (same approach) - VZMacAuxiliaryStorage creation is independent of machineIdentifier - VZMacMachineIdentifier only requires Data representation, not file source - No binding or validation between components **Conclusion:** - ✅ No compatibility issues - ✅ Matches security-pcc official implementation - ✅ Proper handling of first-boot creation and data recovery - ✅ Safe to use Delete VPhoneVirtualMachineRefactored.swift refactor: integrate machineIdentifier into config.plist Move machineIdentifier storage from standalone machineIdentifier.bin file into the central config.plist manifest for simpler VM configuration. **Changes:** - VPhoneVirtualMachineManifest: Remove machineIDFile field - VPhoneVirtualMachine: Load/create machineIdentifier from manifest - VPhoneCLI: Remove --machine-id parameter, require --config - Makefile: Remove --machine-id from boot/boot_dfu targets - vm_manifest.py: Remove machineIDFile from manifest structure **Behavior:** - First boot: Creates machineIdentifier and saves to config.plist - Subsequent boots: Loads machineIdentifier from config.plist - Invalid/empty machineIdentifier: Auto-regenerates and updates manifest - All VM configuration now centralized in single config.plist file **File cleanup:** - Move VPhoneVirtualMachineRefactored.swift to research/ as reference Co-Authored-By: Claude Sonnet 4.6 --- Makefile | 38 +-- README.md | 17 +- docs/README_ja.md | 19 +- docs/README_ko.md | 19 +- docs/README_zh.md | 19 +- .../machine_identifier_storage_analysis.md | 181 ++++++++++++ research/manifest_and_refactoring_summary.md | 271 ++++++++++++++++++ scripts/vm_create.sh | 24 +- scripts/vm_manifest.py | 127 ++++++++ sources/vphone-cli/VPhoneAppDelegate.swift | 55 ++-- sources/vphone-cli/VPhoneCLI.swift | 84 +++++- sources/vphone-cli/VPhoneError.swift | 9 + sources/vphone-cli/VPhoneMenuController.swift | 6 +- sources/vphone-cli/VPhoneVirtualMachine.swift | 79 +++-- .../VPhoneVirtualMachineManifest.swift | 180 ++++++++++++ 15 files changed, 1026 insertions(+), 102 deletions(-) create mode 100644 research/machine_identifier_storage_analysis.md create mode 100644 research/manifest_and_refactoring_summary.md create mode 100755 scripts/vm_manifest.py create mode 100644 sources/vphone-cli/VPhoneVirtualMachineManifest.swift diff --git a/Makefile b/Makefile index d3b39e7..945f345 100644 --- a/Makefile +++ b/Makefile @@ -4,13 +4,12 @@ # ─── Configuration (override with make VAR=value) ───────────────── VM_DIR ?= vm -CPU ?= 8 -MEMORY ?= 8192 -DISK_SIZE ?= 64 -CFW_INPUT ?= cfw_input -RESTORE_UDID ?= -RESTORE_ECID ?= -IRECOVERY_ECID ?= +CPU ?= 8 # CPU cores (only used during vm_new) +MEMORY ?= 8192 # Memory in MB (only used during vm_new) +DISK_SIZE ?= 64 # Disk size in GB (only used during vm_new) +RESTORE_UDID ?= # UDID for restore operations +RESTORE_ECID ?= # ECID for restore operations +IRECOVERY_ECID ?= # ECID for irecovery operations # ─── Build info ────────────────────────────────────────────────── GIT_HASH := $(shell git rev-parse --short HEAD 2>/dev/null || echo "unknown") @@ -57,20 +56,24 @@ help: @echo " make clean Remove all build artifacts (keeps IPSWs)" @echo "" @echo "VM management:" -
