Re: Failing C API tests on Linux

2019-10-31 Thread deepak 
It turns out I had not built the ZooKeeper core before building the C API
(it had a class not found exception in logs).  After building the ZooKeeper
core, trying to build the C API still gives me failures (see below).  Could
someone help me with this?  How should I go about figuring out what is
wrong?

Zookeeper_simpleSystem::testAsyncWatcherAutoResetterminate called after
throwing an instance of 'CppUnit::Exception'

If I uncomment just the testAsyncWatcherAutoReset in tests/TestClient.cc,
then I get a whole bunch of other failures:

Try SnapshotFormatter:

https://stackoverflow.com/questions/17894808/how-do-one-read-the-zookeeper-transaction-log

We might need to have a SnapshotToolkit tool to verify snapshot files similar 
to TxnLogToolkit.
