Unfortunately this is not so easy to resolve, because bbstored does not
currently keep track of that statistic in the store info file, so to find
it out would require scanning the entire store, making this command run
very slowly :(
I'm working on a change which will add extra info to the store file, e.g.
numbers of files in various states, and I will add this value to the ones
that bbstored will keep track of in the store info file. However, this
requires a change to the store info format, which breaks backwards
compatibility of the store.
I will make it automatically upgrade store info files in the old format,
so that it will just work transparently on upgrade, but this will make it
harder to downgrade to an older version of bbstored on the server. I think
that the store info file can be completely regenerated by "bbstoreaccounts
check fix", so that it will be possible to revert, but only after running
"bbstoraccounts check fix" on all accounts.
I've therefore been holding back this change until after the release of
0.11. However, if there's a consensus that this feature is useful enough
to warrant this breaking of store compatibility, I will definitely
consider merging it as soon as it's done. So please let me know if you'd
like or not like to see this feature in 0.11.
The new format will make it much easier to add new store parameters in
future without breaking backwards compatibility, and also includes the
ability to set a text string as the "name" of an account, which many
people have requested (as a workaround for the fact that hexadecimal
account numbers are not very user-friendly), and also a "bbstoreaccounts
list" command to list all accounts with their names.
