* twrpDigest refactorbigbiff bigbiff2017-06-171-52/+0
| | | | | | | | | | | | | | | | | | | This patch is to refactor twrpDigest using polymorphism and inheritance to use the same call patterns for creating and reading a digest. Now a library. Use SHA2 from libcrypto. SHA2 is default if device has libcrypto. Change string MD5 everywhere to use digest or Digest instead. Updated string tags to digest. Translation will be required. Switch out digest code into a driver class from partitionmanager. SHA2 is better for digest creation due to decreased collision space compared to MD5 and SHA1. See https://en.wikipedia.org/wiki/SHA-2 Change-Id: I74b5546789990b12aa4ce2e389d25f80a3fe213f
* MD5 verification sanityJames Christopher Adduono2016-11-301-0/+8
| | | | | | | | | | | | | We can use switches and enums to make things more understandable and work with results in a more sensible manner. PS2: Move file MD5 verification and error handling into a separate function to reduce code. PS3: Default to false in Check_Restore_File_MD5 function Change-Id: Id3ee0bb444cf13be67bb5dec2c43f7c26a86b954 (cherry picked from commit 5c3950716e5c7c6279efd5f3f338d6d22e5215e2)
* ADB: Add adb backup for TWRP.bigbiff2016-08-011-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Functionality for client side to backup tar and image streams over adbd to the client under backup.ab. Using adb backup on the client side you can backup the partitions TWRP knows about. On the client side you can do the following: adb backup -f <filename> --twrp <options> where options are --compress: compress data system: backup system cache: backup cache data: backup data boot: backup boot etc for each partition. You can string multiple options, i.e. adb backup -f <filename> --twrp --compress cache system data adb backup in TWRP will take any option corresponding to TWRP fstab partitions, e.g. efs boot as well. If you do not specify the filename with the -f option, adb will backup your data to a filename backup.ab on the client. You can then rename the file and encrypt it with desktop tools. If you don't want to use command line arguments: adb backup --twrp will bring up the gui and allow you to choose partitions from the backup page. To restore the backup use the following convention: adb restore <filename> Structures are used to store metadata in binary inside of the file itself. If the metadata structure is modified, update the adb version so that it will invalidate older backups and not cause issues on restore. When restoring, we currently do not support picking specific partitions. It's all or nothing. Change-Id: Idb92c37fc9801dc8d89ed2a4570e9d12e76facf8
* Improve progress bar handling for backup / restore / image flashEthan Yonker2016-03-311-2/+2
| | | | | | | | | | | | | | | | | The progress bar will now be updated during image backups, restores and during image flashing (except for sparse images which will require significant changes to libsparse, and except for mtd nand using flash_utils). The progress bar will now be updated mid-file for file systems (tar) so the user will see changes even during large file backup / restore. Add a new progress tracking class to simplify handling of progress bar updates. The class will only update the progress bar 5 times a second to reduce the CPU load from updating the GUI frequently which does affect backup times.
