Does not work with Chrome IndexedDB files?

[bman654]

Hi,

I tried to use this to open some leveldb files used by Chrome's indexedb. I get this error when I try to "connect" to the leveldb folder:

13:06:09.747: Fail connect to server: Invalid argument: idb_cmp1 does not match existing comparator : leveldb.BytewiseComparator!

Anyway to fix that?

Hi @bman654 , you are right now not working with IndexedDB, need to implement comparator something like this: https://cs.chromium.org/chromium/src/content/browser/indexed_db/indexed_db_backing_store.cc?sq=package:chromium&type=cs&l=3902 I will try to scratch sources and implement IndexedDB comparator in FastoNoSQL.

Implemented IndexedDB support, keys can be in binary formats, we hexed it for displaying, but in current moment impossible receive value by key(binary).

Fixed value receive routine. In next release (1.7.0) you can try how it work.

Hi, please change comparator in settings.

Hi @AntonKukoba1 , did you try to change comparator in settings, which result you have?

[AntonKukoba1]

Yep changing the comparator in the Connection settings helps to open the database, though this doesn't help with the data representation, keys and values are all binary. For values there's at least a way to show it as various formats, but the keys are always hex...

[topilski]

May be keys/values should be binaries? Which commands you using for write this items?

Also try to play with compression.

It won't work, you will have to implement native V8 deserializer and key decoder.
