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).
This is meant for a "permanent" tear-down before freeing the memory
holding the VM state or at program shutdown. As a consequence, builtin
sub-systems registering resources are now required to pass a "destroy"
function pointer that will be called just before the memory holding
those resources is freed by the VM resource manager (ie, the manager
owns the resource memory block, but each subsystem is responsible for
cleaning up any resources held within that block).
This even enhances thread-safety in rua_obj (there are some problems
with cmd, cvar, and gib).
This is an extremely extensive patch as it hits every cvar, and every
usage of the cvars. Cvars no longer store the value they control,
instead, they use a cexpr value object to reference the value and
specify the value's type (currently, a null type is used for strings).
Non-string cvars are passed through cexpr, allowing expressions in the
cvars' settings. Also, cvars have returned to an enhanced version of the
original (id quake) registration scheme.
As a minor benefit, relevant code having direct access to the
cvar-controlled variables is probably a slight optimization as it
removed a pointer dereference, and the variables can be located for data
locality.
The static cvar descriptors are made private as an additional safety
layer, though there's nothing stopping external modification via
Cvar_FindVar (which is needed for adding listeners).
While not used yet (partly due to working out the design), cvars can
have a validation function.
Registering a cvar allows a primary listener (and its data) to be
specified: it will always be called first when the cvar is modified. The
combination of proper listeners and direct access to the controlled
variable greatly simplifies the more complex cvar interactions as much
less null checking is required, and there's no need for one cvar's
callback to call another's.
nq-x11 is known to work at least well enough for the demos. More testing
will come.
This is the bulk of the work for recording the resource pointer with
with builtin data. I don't know how much of a difference it makes for
most things, but it's probably pretty big for qwaq-curses due to the
very high number of calls to the curses builtins.
Closes#26
It now takes the function name to print in error message (passed on to
PR_Sprintf) and the argument number of the format string. The variable
arguments (in ...) are assumed to be immediately after the format
argument.
or 512kW (kilowatts? :P). Barely enough for vkgen to run (it runs out if
auto release is run during scan_types, probably due to fragmentation). I
imagine I need to look into better memory management schemes, especially
since I want to make zone allocations 64-byte aligned (instead of the
current 8). And it doesn't help that 16 words per allocation are
dedicated to the zone management.
Anyway, with this, vgken runs and produces sufficiently correct results
for the rest of QF to build, so long as qfcc is not optimizing.
It doesn't do much good for dynamic progs memory because zone currently
aligns to 8 bytes (oops, forgot to fix that), but at least the stack and
globals are properly aligned.
This is part of the work for #26 (Record resource pointer with builtin
function data). Currently, the data pointer gets as far as the
per-instance VM function table (I don't feel like tackling the job of
converting all the builtin functions tonight). All the builtin modules
that register a resources data block pass that block on to
PR_RegisterBuiltins.
This will make it possible for the engine to set up their parameter
pointers when running Ruamoko progs. At this stage, it doesn't matter
*too* much, except for varargs functions, because no builtin yet takes
anything larger than a float quaternion, but it will be critical when
double or long vec3 and vec4 values are passed.
They are both gone, and pr_pointer_t is now pr_ptr_t (pointer may be a
little clearer than ptr, but ptr is consistent with things like intptr,
and keeps the type name short).
Until now, the new qwaq startup was used only in command-line tools and
console applications where things like Ruamoko security and having a
hunk were not an issue. Now the start up code (qwaq-*.c) can specify
that Ruamoko is to be secured and provide a hunk on a per-thread basis,
and the thread data is passed into the progs code via a progs resource.
qwaq-curses has its place, but its use for running vkgen was really a
placeholder because I didn't feel like sorting out the different
initialization requirements at the time. qwaq-cmd has the (currently
unnecessary) threading power of qwaq-curses, but doesn't include any UI
stuff and thus doesn't need curses. The work also paves the way for
qwaq-x11 to become a proper engine (though sorting out its init will be
taken care of later).
Fixes#15.
This refactors (as such) keys.c so that it no longer depends on console
or gib, and pulls keys out of video targets. The eventual plan is to
move all high-level general input handling into libQFinput, and probably
low-level (eg, /dev/input handling for joysticks etc on Linux).
Fixes#8
QF now uses its own configuration file (quakeforge.cfg for now) rather
than overwriting config.cfg so that people trying out QF in their normal
quake installs don't trash their config.cfg for other quake clients. If
quakeforge.cfg is present, all other config files are ignored except
that quake.rc is scanned for a startdemos command and that is executed.
While this caused some trouble for pr_strings and configurable strftime
(evil hacks abound), it's the result of discovering an ancient (from
maybe as early as 2004, definitely before 2012) bug in qwaq's printing
that somehow got past months of trial-by-fire testing (origin understood
thanks to the warning finding it).
It now takes a context pointer (opaque data) that holds the buffers it
uses for the temporary strings. If the context pointer is null, a static
context is used (making those uses of va NOT thread-safe). Most calls to
va use the static context, but all such calls have been formatted
consistently so they are easy to find when it comes time to do a full
audit.
There's still some cleanup to do, but everything seems to be working
nicely: `make -j` works, `make distcheck` passes. There is probably
plenty of bitrot in the package directories (RPM, debian), though.
The vc project files have been removed since those versions are way out
of date and quakeforge is pretty much dependent on gcc now anyway.
Most of the old Makefile.am files are now Makemodule.am. This should
allow for new Makefile.am files that allow local building (to be added
on an as-needed bases). The current remaining Makefile.am files are for
standalone sub-projects.a
The installable bins are currently built in the top-level build
directory. This may change if the clutter gets to be too much.
While this does make a noticeable difference in build times, the main
reason for the switch was to take care of the growing dependency issues:
now it's possible to build tools for code generation (eg, using qfcc and
ruamoko programs for code-gen).
I decided that stopping in between function calls that are on the same
line is a good thing as it gives a chance to skip over the first but
step into the second.
This allows a debugger to do any symbol lookups and other preparations
between loading progs and the first code execution. .ctors are called as
per normal if debug_handler is not set.
While this does answer the question of how I'll go about restarting the
target progs (when I get to that point), it was required just to start
full-on ruamoko progs because .ctor was getting run in the main thread
and blocking due to trace.
Things were getting rather cluttered with everything being qwaq-* and
all in one directory. Now most have lost the qwaq- prefix and have been
moved into subdirectories (non-recursive make).
