Test Tools for Key/Value Stores

NeoMutt uses a key/value store, e.g. lmdb, as a cache for email headers.

This repo contains some test tools to work with these stores.

lmdb-dump.c

Dump the contents of an LMDB store.

build:

gcc lmdb-dump.c -o lmdb-dump -llmdb

run:

./lmdb-dump store-file

output:

Opening store-file
key: /home/flatcap/mail/1679930513.M731552P185191.flatcap.org,S=5071,W=5169
	data length: 999
key: /home/flatcap/mail/1679932108.M761797P185751.flatcap.org,S=5055,W=5153
	data length: 1008

lmdb-cull.c

Cull a percentage of the contents of an LMDB store.

build:

gcc lmdb-cull.c -o lmdb-cull -llmdb

run:

# Delete a random 30% of the records
./lmdb-cull store-file 30

output:
