Uncovered by the memory leak cleanup: the nodes were all being "linked"
to the first node, those nodes in between the first and last were
getting lost.
This was mainly for the shutdown functions, thus allowing Sys_Shutdown
(and Sys_RegisterShutdown) to be per-thread, but it seemed like a good
idea to make everything per-thread.
Finally, hash links can be freed when the hash context is no longer
relevant. The context is created automatically when needed, and the
owner can delete the context when its done with the relevant hash
tables.
It should have been this way all along, and it seems I thought they were
when I did rua_gui.c as it already freed its resource block, which would
have been a double free (oops). Fixes an invalid write when shutting
down progs in qwaq-cmd (relevant change not committed).
I tried out -std=c2x (doesn't work due to typeof (gcc bug?)) and
-sdt=gnu2x (still no #embed) and found that only regex.c was a problem
(nice), and now it no longer is a problem.
Render passes and subpasses are now mostly initialized, just command
buffers and frame buffer related info to go (including view/scissor for
pipelines).
Due to a typo in the list of extra property list items to add to the
symbol table (corrected), subsequent symbols were pointing to the wrong
memory address.
Not only does this quieten the validation layers, it ensures that all
the object handles are named and where they need to be. Also fixes only
one pipeline being created instead of the 15 or so.
It turns out labeled arrays don't work if structs aren't declared in the
right order (no idea what that is, though) as the struct might not have
been processed when the labeled array field is initialized. Thus, do a
pro-processing pass to set up any parse data prior to writing the
tables.
Most importantly, this cleans up creation of self-referencing symbol
tables from property lists, but adds in C-defined symbols as well. While
QFV_ParseRenderInfo is currently the only the function that uses it, it
might be helpful in the future, especially as I clean up the other parse
support code.
The render passes seem to be created successfully, but pipelines fail
due to not having layout set, resulting in a segfault (bug in validation
layers?).
I don't remember why I kept the abbreviated configs for images and image
views, but it because such that I need to be able to specify them
completely. In addition, image views support external images.
The rest was just cleaning up after the changes to qfv_resobj_t.
Vulkan requires color blend state is only for color attachments (ignored
otherwise), but it shouldn't be necessary to actually specify the blend
state and instead have it default to something reasonable.
Unfortunately, colorWriteMask affects the output even if blending is
disabled, so it must be initialized to something reasonable (r|g|b|a)
for when the default is used.
.dictionary can ask for standard parsing via a .parse key (value is
ignored currently).
Fields can use $auto to use standard parsing for that field.
If either is used, the plist field descriptors are written.
They're currently just stubs, but this gets the render info loading
working without any errors. The next step is to connect up pipelines and
create the image resources, then implementing the task functions will
have meaning.
This gets an empty (no tasks or pipelines connected) render context
initialized and available for other subsystems to register their task
functions. Nothing is using it yet, but the test parse of rp_main_def
fails gracefully (needs those tasks).
This just sets up the memory block and cexpr descriptors for the
parameters, parameter parsing is separate (and next). The parameters are
aligned to their size.
Needed to add the render passes plitem to the cexr symbol table, too.
All that remains is to figure out how to deal with multiview (or really
@next) and get task parsing working.
