Trying levedb jna about leveldb-jna HOT 9 CLOSED

Hello Roman,

Sorry, didn't get your question. Could you please explain what you mean by "good testing"?

from leveldb-jna.

Hey Max,
@maxd

I mean I've tried jnileveldb and it looked ok
and working and suddenly we found out
a memory leak in the leveldb (the version they use).

Did you tried any big load with the version you use ?

Thanks
Roman

No, I didn't test leveldb-jna over big workload. Do you have memory leak on Windows platform?

from leveldb-jna.

@maxd : I got that memory leak on both win and ubuntu
why ? do you know about some special problems with leveldb
on win ?

from leveldb-jna.

LevelDB doesn't support Windows platform. leveldb-jna and jnileveldb are using third-party LevelDB port for support Windows platform. So, it can has different problems.

Probably your problem related to outdated version of LevelDB because jnileveldb compiled with version 1.12 (version 1.18 is latest). For investigate it you can review commits in LevelDB repository because they describe all changes since 1.12 or create small project and try to reproduce memory leak with leveldb-jna library.

@maxd : yep the version difference is the reason
I will to try it. One last question:

When you pass key/value to leveldb by the bridge
are doing it by ref or by value (copy) ?

from leveldb-jna.

By reference. It mention here:

The memory provided by a Java primitive array will only be valid for use by the native code for the duration of the function call.
