version upgrade

  • image core and wallet.dat upgraded from v0.13.1.2 to v0.13.1.3
  • imagecoind of v0.13.1.2 and v0.13.1.3 can coexist in the network
  • Low version imagecoind cannot read high version of wallet.dat
  • High version imagecoind can read lower version of wallet.dat

scenes to be used

1. Create a new address, import an existing address

  • Related transactions for this address, data other than imagebase64 fields will still be saved to wallet.dat
  • The imagebase64 field is saved in ~/.imagecoind/image/image.dat

2. imagecoin-qt

  • No changes in use
  • No perception of coin separation

3. imagecoind restart

  • wallet.dat will still make backups in ~/.imagecoind/backups
  • image.dat does not make backups

4. wallet.dat is damaged or missing

  • Import the private key with the backup wallet.dat, the system will re-download the relevant transaction
  • Subsequent process reference case#1

5. image.dat is damaged or missing

  • If imagecoind is found to be unreadable or does not match wallet.dat at startup
  • imagecoind will go online to download related transactions for all addresses in wallet.dat
  • Subsequent process reference case#1

6. -salvagewallet parameter

  • will re-download tx and image data
  • Subsequent process reference case#1

7. -rescan parameter

  • will re-download tx and image data
  • Subsequent process reference case#1

8. Compatibility 1

  • The upgraded program (>=v0.13.1.3) will move the image data from the old wallet.dat to ~/.imagecoind/image/image.dat on the first boot.
  • Leave only data outside the imagebase64 field in wallet.dat
  • Subsequent process reference case#1

9. Compatibility 2

  • If the old program (<=v0.13.1.2) starts up and finds that the wallet.dat version is higher than itself (>=v0.13.1.3), it will exit with an error.

10. movecmd, transfer

  • Not affected by any

  • Other data is saved in ~/.imagecoind/wallet.dat

case2: Do not directly backup the backup

  • Upgrade ImageCoind/ImageCoind-qt, launch ImageCoind/ImageCoind-qt
