Riak 2.2.0 and PHP7 support

[kodekraft]

Which versions of the basho/riak-pb and basho/protobuf packages should I use to accommodate Riak 2.2.0 and PHP7?

I'm currently using the following branch for my PHP extension:
https://github.com/basho/php-protobuf/commits/serggp_php7

because this is the only one that works. I tried the php7_merge branch but that resulted in a segfault from php-fpm.

The php7-merge branch is the ideal branch. Can you share the errors you received on it? I was able to run all of our integration tests against it from our Riak Client library: https://travis-ci.org/basho/riak-phppb-client/builds/197525530

Hi Chris,

All the tests passed for me too when I ran the make tests.
Here was the error produced in the httpd error_log:

If I restart the php-fpm service, I can execute a single riak transaction, but the next one and all subsequent transactions will fail.

When I checkout and compile the serggp_php7 branch, I don't have this issue.

@kodekraft Try rebuilding the module again, but first do a make distclean on the build files before doing the make and make install. I have had this issue sometimes when attempting to build the module with an unclean directory with leftover build files from previous attempts.
