Reproduction Steps

import blocksci

chain = blocksci.Blockchain("/mnt/blocksci/blocksci.conf")

# wasabi coordinator address, several thousand transactions
address = chain.address_from_string("bc1qs604c7jv6amk4cxqlnvuxv26hv3e48cds4m0ew")
address.txes.output_count

System Information

Using AMI: no, guix package for blocksci: https://github.com/nothingmuch/guix/commit/29eca3a9b9cdc82efe02c2c6fc54ecb3bc3cae6e BlockSci version: 4e26aae493674e46ff4a13b9187e1e272f4bb0ca Blockchain: Bitcoin Parser: Disk Total memory: 128GB when building index, 16 GB when running query

This should be reproducible with guix. If you want to try, you should be able to install it on any linux distro (i used debian 9), then to get my package definitions

guix pull --url=https://github.com/nothingmuch/guix.git --commit=04fb98289da8b9feba749d747bf02358f76045ab
guix environment --ad-hoc blocksci{,py} python -- python3 segfault.py

I will proceed to try with a debug compilation (see latest commit to blockscipy-0.6 branch) and update with a more detailed backtrace.

The data directory was built by running core-update against a freshly synced 0.18.0 release of bitcoin core, with update run after catching up with tip to build the indices. I attempted to compact-indexes to see if that would persuade rocksdb to rebuild something, but saw no change in behaviour.

[nothingmuch]

sorry, correct guix commit should be 04fb98289da8b9feba749d747bf02358f76045ab, the commit in the original report is not stable (names branch not commit in package definition).

[maltemoeser]

This error doesn't occur on my BlockSci instance, could you run a full parse with a normal update instead of core-update? core-update does not update address indexes, which are needed if you want to look up transactions corresponding to an address.

[nothingmuch]

FWIW with the debug build, instead of a segfault i'm seeing assert(valid_) fail in the rocksdb iterator code:

python3: /tmp/guix-build-blocksci-4e26aae493674e46ff4a13b9187e1e272f4bb0ca.drv-0/source/external/rocksdb/db/db_iter.cc:173: virtual rocksdb::Slice rocksdb::DBIter::key() const: Assertion `valid_' failed.

Unfortunately I didn't manage to build blockscipy itself with debugging enabled, after running python ./setup.py build --debug, the install phase triggers recompilation, still looking into this.

Next, I'll try again with update right from the start.

Is there a point in trying with #266 or 0.5? I ask about the former since range is involved in the backtraces, but I only read a bit of the backtrace code so far, and understood even less, so no theory as to what caused the assertion failure yet.

[nothingmuch]

seeing the same behaviour with a newly created blocksci directory
