Incompatible module code with Zabbix 3.0.X #89

vitassecuriti · 2018-01-22T15:52:35Z

Hi!

I try to build an image according to the instruction for branches/3.0 or tags/3.0.8 on an image of centos. I receive such mistake.
In the Dockerfile file I set value of the ENV ZABBIX_VERSION=branches/3.0 variable
or ENV ZABBIX_VERSION=tags/3.0.8. and every time I receive a error

gcc -fPIC -shared -o zabbix_module_docker.so zabbix_module_docker.c -I../../../include -I../../../src/libs/zbxsysinfo
zabbix_module_docker.c: In function 'zbx_docker_dir_detect':

                 if (SUCCEED != zbx_regexp_sub(path, mounts_regex, "\\1", &stat_dir) || NULL == stat_dir)
                 ^

I need to compile with the tag 3.0.8 since doesn't work with the zabbix_module_docker.so file which I have downloaded already compiled for version 3.0 zabbix-agent.

Yes, you are right @vitassecuriti. The current master code is not compatible with Zabbix 3.0, because #80.

Quick workaround: build tagged version before tag 0.6.8
I'll try to fix it later.

For the record, zbx_regexp_sub functions:
Zabbix 3.4.6:

int     zbx_regexp_sub(const char *string, const char *pattern, const char *output_template, char **out)
{
        return regexp_sub(string, pattern, output_template, REG_EXTENDED | REG_NEWLINE, out);
}

Zabbix 3.0.8:

char    *zbx_regexp_sub(const char *string, const char *pattern, const char *output_template)
{
        return regexp_sub(string, pattern, output_template, REG_EXTENDED | REG_NEWLINE);
}

Thanks for the answer. I have tested for earlier versions. the mistake is present.

So, workaround hasn't helped.
It is necessary to wait for correction of a bug.

You need to use tagged module source code version. For example v0.6.7: https://github.com/monitoringartist/zabbix-docker-monitoring/blob/v0.6.7/src/modules/zabbix_module_docker/zabbix_module_docker.c
It doesn't use zbx_regexp_sub function, so you can't have error error: too many arguments to function 'zbx_regexp_sub' there.

vitassecuriti · 2018-01-23T14:14:42Z

Sorry? I probably haven't so understood

jangaraj · 2018-01-23T14:20:35Z

Module has releases - https://github.com/monitoringartist/zabbix-docker-monitoring/releases
Unfortunately, https://github.com/monitoringartist/zabbix-docker-monitoring#compilation and Dockerfiles use only master branch code, which is not compatible with your Zabbix 3.0, so pls modify them and instead of master branch use tag 0.6.7 in your compilation process.

vitassecuriti · 2018-01-23T14:29:30Z

Once again I apologize, Really, the decision works
I have changed a line in the dockerfile, having added parameter
git clone -q -b v0.6.7 https://github.com/monitoringartist/zabbix-docker-monitoring && \
so the image was constructed without error
