py-leveldb's Issues

PyLint error for leveldb.LevelDB()

I run py-leveldb successfully, but pylint always show this error message:
pylint message: 'E1101:Module 'leveldb' has no 'LevelDB' member'

My env is macOS 10.12.5, python 2.7.10, IDE tool is VSCode.

PIP Install issue for leveldb with python3.4.2

I am getting an error very similar to the one described here . https://groups.google.com/forum/#!topic/py-leveldb/VpVtc9hJatw . I am installing the package using pip. I also tried the solution provided in the forum and works fine for me. Can you please fix this so that pip3 install leveldb doesn't doesnt throw errors.

Here is what I get ::

Cygwin support

The current release seems not supporting Cygwin platform. I got the error below.

$ uname -a
CYGWIN_NT-6.1 Dell 1.7.33-2(0.280/5/3) 2014-11-13 15:47 x86_64 Cygwin
$ python setup.py build
Don't know how to compile leveldb for CYGWIN_NT-6.1!

The latest leveldb has added support fow Cygwin, see here, though I recently found it's not working sometimes.

I managed to install py-leveldb on Cygwin after I applied the following changes:

I wonder if we can add this feature.

bloom filter

Do not support setup a bloom filter to leveldb at the very beginning ? and why ?

Update levedb

Hi,

it would be great if the pypi package would be up to date.
The underlying leveldb version is 1.7 and it would be great if it would be updated to a newer version.

Thank you.

remove ez_setup import

It would be great if the import of ez_setup would be removed completely.

It makes no sense to run this setup.py in a specific and old version of setuptools.

Thank you.

PS: I'm not the only one that wants that removed but somehow the tickets created at https://code.google.com/p/py-leveldb weren't forward to you.

tagging releases

Would you mind adding git tags to this repo to correspond to the releases on PyPI?

Status of this project?

First of all, thanks for putting this project out there.

Given the last commit is of 5 years ago what is the status of this project and the corresponding PyPI package? There is also https://github.com/arnimarj/py-leveldb which appears to be older.

If you're interested I've made some changes to address issue and add Python 3.12 support. If you're interested in a PR let me know.
