leveldb.jl's Issues

Iterating over DB will causes double free crash when db is closed

Julia version : Version 1.2.0-DEV.426 (2019-03-06)

Registrator

@jerryzhenleicai Sorry to bother you. Could you please install @JuliaRegistrator to this repo. Thanks!

I am trying to make a new release. So far I always used Attobot but cannot install it on this repo, I think that only the owner can do it. I installed Attobot on my fork but it does not seem to work. Can you please install Attobot and activate it for this repo.

You can find a description here: https://github.com/attobot/attobot

I also asked, but did not get a reply yet: attobot/attobot#60

Registrator test

@JuliaRegistrator register()

consider switch to BinaryBuilder?

see BinaryBuilder.jl and BinaryProvider.jl.

Support for arbitrary keys and values

It seems that this module only supports Vector{UInt8} keys and values, which makes it pretty unusable.

Why not add support for general types?

E.g. something like:

using LevelDB
using Serialization

function obj2buf(t::T) where T
    io = IOBuffer()
    serialize(io, t)
    return take!(io)
end

buf2obj(v::Vector{UInt8}) = deserialize(IOBuffer(v))

Base.setindex!(db::LevelDB.DB, i::T, v::S) where {T,S} = Base.setindex!(db, obj2buf(i), obj2buf(v))
Base.getindex(db::LevelDB.DB, i::T) where T = buf2obj(Base.getindex(db, obj2buf(i)))

...

db = LevelDB.DB("level.db", create_if_missing = true)
db["aa"] = "bb"
db["aa"]
# "aa"

Obviously, a faster/more stable serialization should be used -- e.g. code from JLD2 could be used.

LevelDB doesn't compile on Julia 1.7.2 on MacOS aarch64 (Apple Silicon)
