OS kali-linux

version 0.8 work`s fine and in 0.9 i have this issue

Starting program: venv/bin/python index_db_test.py [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Program received signal SIGSEGV, Segmentation fault. 0x00007ffff662c18d in leveldb::InternalFilterPolicy::CreateFilter(leveldb::Slice const, int, std::__cxx11::basic_string<char, std::char_traits, std::allocator >) const () from /usr/lib/x86_64-linux-gnu/libleveldb.so.1

[wbolster]

likely not a plyvel issue since it does not call this leveldb api directly

[wbolster]

try removing .cache/pip from your homedir and rebuild in fresh venv

if i downgrade to v 0.8 all my source works, and with 0.9 not magic?)

[wbolster]

https://github.com/wbolster/plyvel/compare/0.8...0.9

if you look at the diff between 0.8 and 0.9 the actual code has only one change, which seems not relevant here.

i suspect cached builds or something unexpected like that on your side.

also, i doubt that is the complete backtrace? can you reproduce under gdb and share "thread apply all bt" output?

[wbolster]

i do not see any backtraces... see earlier comments.

also try completely fresh installs, remove .pip/cache, venvs, and so on. other people have had issues with that before.

[wbolster]

leveldb versions are the same?

https://github.com/google/leveldb/issues/425

[ghost]

yes all same, the only version of plyvel changed, and this is the full traceback

[ghost]

as test chrome version 60+ indexdb you can try it by your hands C:\Users\USERNAME\AppData\Local\Google\Chrome\User Data\Default\Local Storage

[wbolster]

in a fresh virtualenv using python3.5:

$ pip install plyvel
[...]
Successfully installed plyvel-0.9

this works without error:

>>> import plyvel
>>> db = plyvel.DB('testdb', create_if_missing=True)
>>> db.put(b'foo', b'bar')
>>> db.get(b'foo')
b'bar'
>>> db.close()

i can also open ~/.config/chromium/Default/Local Storage/leveldb (i made a copy first) without problems:

[Python 3.5.2, IPython 6.2.1, sys.prefix ~/.virtualenvs/tmp-9cd801a3b41874cf]
>>> import plyvel
>>> db = plyvel.DB('/tmp/chromium-db/')
>>> it = db.iterator()
>>> next(it)
(b'META:chrome-devtools://devtools', b'...')
>>> db.close()
