I had messed up the handling of declarators for combinations of pointer,
function, and array: the pointer would get lost (and presumably arrays
of functions etc). I think I had gotten confused and thought things were
a tree rather than a simple list, but Holub set me straight once again
(I've never regretted getting that book). Once I understood that, it was
just a matter of finding all the places that needed to be fixed. Nicely,
most of the duplicated code has been refactored and should be easier to
debug in the future.
It turns out I broke the type system when it comes to pointers to
functions and arrays. This test checks basic function and array pointers
and passes with qfcc from before the type system rework.
I'm not sure just what was going on other than *other* components were
getting double-removed when the hierarchy reference component was
removed when the entity was being deleted. This might even prevent
issues with removing the hierarchy from an entity that's not being
deleted as the pre-invalidation prevents the removal from deleting the
entity.
It turns out that the fixes for other problems related to removing
hierarchy reference components fixed the problem moving the entity
invalidation fixed, and invalidating the entity late somehow broke the
sprite renderer (at least in glsl).
The hierarchy leak was particularly troublesome to fix, but now the
hierarchies get updated (and freed) automatically just by removing the
hierarchy reference component from the entity. I suspect there will be
issues with entities that are on multiple hierarchies, but I'll sort
that out later.
It turns out that the bsearch bug was hiding incorrect handling of
indices in the subpool beyond the last tracked subpool. In which case, a
correctly working bsearch correctly fails to find the range, but the
search can be skipped entirely.
And rename _bsearch to QF_bsearch_r since that's far less confusing.
Also, update the test to make it possible for valgrind to detect the
out-by-one. The problem was found when trying to remove components from
an entity when using subpools.
I'm not 100% sure this is the best fix for the issue, but the way the
cbuf interpreter stack works (especially in the console code) meant that
the stack was built in the order opposite to how it could be safely
deleted with the existing function. Yeah, more leaks :P
Some of them, especially in rua_obj, were quite legitimate and even a
problem for thread-safety (rua_cmd is currently not thread-safe, but it
needs a lock, which I don't feel like doing at this stage).
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.
