Anton Duzenko's questions

I have a file storage directory used together with a MySQL DB.

Some of the files in the directory are orphaned (i.e. created by mistake, deleted in the DB but not on disk, otherwise not used).

I was able to generate list of such files without file extension but now what's the best way to move them out of the storage directory. The problem is that the storage is multi-level, so I have to find each file first somehow.

Sample of the orphan list content (200K lines in total):

10218
10219
10220
10221
10370
10371
10372
10373
10374

Directory structure (example):

If you wonder how I ended up with such a file:

• first, saved list of files in directory recursively to one file per https://stackoverflow.com/a/5456136/505984
• secondly, dumped DB table id's to another file with MySQL CLI (because each filename without the extension matches the DB record ID)
• diff'ed the two files as advised here: https://stackoverflow.com/a/25407317/505984

I have stumbled into a basic OpenGL driver bug and I'm not sure where to report them.

Here's how the driver identifies itself and how we create the RC:

OpenGL vendor: X.Org
OpenGL renderer: AMD CARRIZO (DRM 3.26.0, 4.18.0-13-generic, LLVM 7.0.0)
OpenGL version: 4.4 (Compatibility Profile) Mesa 18.2.2
v - using GL version 2.0 (core)

It has ARB_gpu_shader5 in its extension list but not EXT_gpu_shader4.

This shader fails to compile

#version 120
#extension GL_EXT_gpu_shader4: enable
...
uniform usampler2D u_stencilTexture;        

With this error:

interaction VFWARNING:CompileShader(glprogs/interaction.fs): FAILED
0:2(12): warning: extension `GL_EXT_gpu_shader4' unsupported in fragment shader
0:27(20): error: syntax error, unexpected NEW_IDENTIFIER, expecting '{'

So my question is: how do I get the version 120 shader with the usampler extension to build on seemingly Opengl-4.4 capable GPU/driver?

Preferably in a cross-platform, cross-vendor way.

Please note that the same shader compiles just fine on a wide range of devices/drivers on both Linux and Windows.
