* Fixes #3048 * Certain programs that read/write KDBX4 files do not consolidate duplicate attachments into a single binary. This is against the KDBX4 specification. This change ensures KeePassXC will at least read the database in its entirety and not lose information. Upon saving the database in KeePassXC, the duplicate attachment binaries will be reduced to single binaries per the specification.

Oh, and one more thing that needs to be tested: correcting binary indices must update the modification date of entries or else we may see weird effects with sync and merge. |

Yes I tested the deduplication on save. It's the same mechanism as if you attached a duplicate file to an entry. We don't do deduplication until the time of saving. This is an area of future improvement with attachments. The modified time should not be changed. We are just updating the ref index of the entry in the xml. There are literally no changes to the entry itself. |
