A new -shutdown <time> option has been created to specify the time when the client will stop asking for new jobs, will finish uploading the frames in the upload queue and will shutdown the computer. The time argument can have two different formats: an absolute date & time in the format yyyy-MM-ddThh:mm:ss (24h format) or a relative time in the format +m where m is the number of minutes from now.
The user can also select the shutdown-mode, where "wait" will wait for all the processes (render + pending uploads) to finish and "hard" will cancel all the pending jobs and will initiate the computer shutdown.
* Fix: EEVEE renders with CPU instead of GPU in Linux clients
In Linux systems, setting the env LD_LIBRARY_PATH var to point the /lib folder included in the sheepit binary compressed .zip, mandates Blender to swap whatever openGL library is already in use by the OS. Modern GPU drivers install their own optimised version of the OpenGL library and replacing it creates incompatibilities that avoid EEVEE to run.
To detect if Blender already uses the standard OS provided OpenGL library is via _ldd_ Linux command. The execution in a system with OpenGL libraries already in use delivers an output similar to this:
ldd rend.exe
linux-vdso.so.1 (0x00007ffda6bf9000)
...
libXfixes.so.3 => /lib/x86_64-linux-gnu/libXfixes.so.3 (0x00007fefefe3a000)
libXrender.so.1 => /lib/x86_64-linux-gnu/libXrender.so.1 (0x00007fefefc30000)
libGL.so.1 => /lib/x86_64-linux-gnu/libGL.so.1 (0x00007fefefb9c000)
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fefefa4d000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fefef85c000)
...
libbsd.so.0 => /lib/x86_64-linux-gnu/libbsd.so.0 (0x00007fefef6e7000)
While a system with no OS OpenGL libraries that requires the shipped default OpenGL lib to work returns this instead:
ldd rend.exe
linux-vdso.so.1 (0x00007ffda6bf9000)
...
libXfixes.so.3 => /lib/x86_64-linux-gnu/libXfixes.so.3 (0x00007fefefe3a000)
libXrender.so.1 => /lib/x86_64-linux-gnu/libXrender.so.1 (0x00007fefefc30000)
libGL.so.1 => not found
libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fefefa4d000)
libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fefef85c000)
...
libbsd.so.0 => /lib/x86_64-linux-gnu/libbsd.so.0 (0x00007fefef6e7000)
In the former case, the SheepIt client will set the LD_LIBRARY_PATH env var to point the /lib folder to allow Blender to execute properly.
* We don't need to shadow in `lombok` itself. Gradle must be upgraded to at least 4.6 to support `annotationProcessor`, which is a version that still supports Java 7.
* `args4j-maven-plugin` is intended to use as a maven plugin.
* The requirement for `jaxb-api` was removed in 81cba7d58c0ce8a334204700dca669f2ad8e16ff
* We are only using `simple-xml`, don't need the whole `retrofit`+`okhttp`+`okio` chain.
* Resolve deprecation warnings in JNA code.
MemFree: The amount of physical RAM, in kilobytes, left unused by the system.
MemAvailable: An estimate of how much memory is available for starting new applications, without swapping.
