gearmand | golang gearman-job-server clone | SSH library

To build gearmand with hiredis persistence queue you have to install libhiredis-devel on CentOS or libhiredis-dev on Debian/Ubuntu package.

Insure ./configure --enable-hiredis output contains

The addServer() method requires a host parameter, even if the gearman server is running locally:

The issue has been resolved. It had nothing to do with Gearman and Docker but with the particular Ubuntu installation. After reformatting, everything worked as it should

The ret_ptr parameter to the function in question is expected to point to a variable in the calling function. This pointer is then dereferenced for both reading and writing this external variable.

The if (ret_ptr == NULL) block checks whether the caller actually passed in the address of some variable. If not, this pointer is then made to point to the local variable unused so that the pointer can still be safely dereferenced later in the code. But since ret_ptr now points to a local, changes made by dereferencing it are not seen outside the function. This is fine, since the caller passed in NULL for ret_ptr. Similarly, since ret_ptr is a parameter, any changes to it are not visible outside of the function.

Nothing needs to be refactored here. The code works as intended with regard to ret_ptr. This is a false positive from PVS-Studio.

EDIT:

This is NOT a false positive. The unused variable is defined at a lower scope than ret_ptr, namely the scope of the first if block in the function. After the if block, ret_ptr is then dereferenced. If it was pointing to ununsed, that variable is now out of scope and dereferencing ret_ptr invokes undefined behavior.

To fix this, unused must be declared and assigned to above the if block:

The container was logging using all the default settings, but my client was pointing to another server, but just to leave a trail.

Inside php_fpm container (docker exec -it dev_php_fpm_1 /bin/bash), you can cat /etc/php5/fpm/php.ini, which shows the default error_log settings:
