Zookeeper SSL C Client Support

Dear Experts,

I see that this PR https://github.com/apache/zookeeper/pull/625 is merged to master to enable Zookeeper C Client SSL support. We are planning to use this in our software. Do you have any plan to release a new version of Zookeeper with this support ?

Thanks,
Pradeep

Hi Pradeep,

based on the logs, it seems working. It is great to see that you will use
it :) Let us know if you would see any issue with it.

FYI, we already have a few improvements under review around these areas:
- https://issues.apache.org/jira/browse/ZOOKEEPER-3567 (Add SSL support for
the zk python client)
- https://issues.apache.org/jira/browse/ZOOKEEPER-3630 (Autodetection of
SSL library during Zookeeper C client build)
- https://issues.apache.org/jira/browse/ZOOKEEPER-3640 (Implement "batch
mode" in cli_mt)

I also created this improvement idea:
https://issues.apache.org/jira/browse/ZOOKEEPER-3646, "Executing multiple
commands non-interactively with the C client cli "
No one is working on it right now AFAIK, but let me know if it would be
important / helpful for you.

Regards,
Mate

Hi Enrico,

I have just tested the cli_st utility as of now. It seems to work ok. I haven't integrated this code in our software yet.  Please check the logs below.


git clone git@github.com:apache/zookeeper.git
cd zookeeper
yum install java-1.8.0-openjdk
yum install ant
yum install autoconf
yum install automake
yum install cppunit
yum install cppunit-devel
ant compile_jute
cd zookeeper-client/zookeeper-client-c/
./configure
vi Makefile
** Uncomment following 2 lines and set OPENSSL_DIR **
#OPENSSL_CPPFLAGS = -DHAVE_OPENSSL_H -I$(OPENSSL_DIR)
#OPENSSL_LIB_LDFLAGS = -lssl -lcrypto
make
make install


Run cli_st utility
