For now, just bsearch (normal and fuzzy), qsort, and prefixsum (not in
C's stdlib that I know of, but I think having native implementations of
float and int prefix sums will be useful.
The server edict arrays are now stored outside of progs memory, only the
entity data itself (ie data accessible to progs via ent.fld) is stored in
progs memory. Many of the changes were due to code accessing edicts and
entity fields directly rather than through the provided macros.
I never liked that some of the macros needed the type as a parameter
(yay typeof and __auto_type) or those that returned a value hid the
return statement so they couldn't be used in assignments.
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.
The problem was caused by passing the index into the dtables array to
dtable_get which expects a handle. A handle is the ones-compliment
negative of the index which means that handle 0 is invalid (but 0 was
being passed... oops). Fixes the segfault when qw-client-x11 connects to
a server.
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The vc project files have been removed since those versions are way out
of date and quakeforge is pretty much dependent on gcc now anyway.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).
Returning a string was a bad idea as it makes str_str difficult to use
with str_mid. (actually, iirc, it was the only reason I moved all
strings into progs memory... hmm).
In testing variable fw/precision in PR_Sprintf, I got a nasty reminder
of the limitations of the current progs ABI: passing @args to another QC
function does not work because the args list gets trampled but the
called function's locals. Thus, the need for a va_copy. It's not quite
the same as C's as it returns the destination args instead of copying
like memcpy, but it does copy the list from the source args to a
temporary buffer that is freed when the calling function returns.
They take a pointer to a free-list used for hashlinks so the hashlink
pools can be per-thread. However, hash tables that are not updated are
always thread-safe, so this affects only updates. progs_t has been set
up such that it is easy for multiple progs within one thread can share
hashlinks.
This returns the character (as an int) at the index. Equivalent to
string[index], but qc code doesn't have char-level access and not having
it means that strings can internally change to wchar without too much
fuss (maybe).
This causes the block to be freed when the forward: handler returns
(assuming it's not yet another builtin). This is necessary so calling a
lot of forwarded messages in a loop doesn't leak memory (though it will
get freed eventually).
With this, object's implementing forward:: seem to accept the message
well, including receiving all the original args (not quite sure how to
deal with them in ruamoko code just yet, though).
libr supplies an __obj_forward definition that links to a builtin, but
as it is the only def in its object file, it is readily replaceable by
an alternative Ruamoko implementation.
The builtin version currently simply errors out (rather facetiously),
but only as a stub to allow progs to load.
This should speed up ruamoko code somewhat as hash table lookups have
been replaced with direct array indexing. As a bonus, support for
message forwarding has been added (though not tested).
Move the semi-permanent resource initialisation into the module init and
the cleanup of those resources into cleanup. Makes actual runtime init
much easier to read.
This is one step closer to implementing conformsToProtocol. However,
protocols are not yet initialized correctly: they are not registered,
nor are their selectors.
While the static initializer list pointer was not written previously,
the module struct always came immediately after the symbols struct, and
the module version has so far always been 0. Thus, the list pointer is
correctly 0 for older progs and there's no need for a version bump.
Other than its blocking of access to certain files, it really wasn't
that useful compared to the functions in qfs, and pointless with access
to qfs anyway.
It is now set to 0 when progs are loaded and every time
PR_ExecuteProgram() returns. This takes care of the default case, but
when setting parameters, pr_argc needs to be set correctly in case a
vararg function is called.
PR_SaveParams() is required for implementing the +initialize diversion
used by Objective-QuakeC because builtins do not have local def spaces
(of course, a normal stack calling convention would help). However, it
is entirely possible for a call to +initialize to trigger another call
to +initialize, thus the need for stacking parameter stashes. As a
bonus, this implementation cleans up some fields in progs_t.
When the substring is the tail of the supplied string, return a
"pointer" to within the supplied string rather than a new "return"
string. This means that tail-end substrings of string constants are
themselves constants.
Only as scalars, I still need to think about what to do for vectors and
quaternions due to param size issues. Also, doubles are not yet
guaranteed to be correctly aligned.
It seems they were written before quaternion support was added and were not
updated to take into account the variable size of parameters. Now at least
Object's -error: works.
Going by "standard" Objective-C, retainCount really doesn't belong in
Object itself. The way GNUStep does it is to stash retainCount in memory
just below the object by allocating extra bytes for the count and returning
a pointer just beyond those extra bytes. Now Ruamoko does the same. This
fixes the inconsistencies in structure layouts for Protocol and class
structs between qfcc generated (internal) structs and user visible structs.
This makes gib depend on gamecode, but removes the dependency on gib from
ruamoko. Unfortunately, carne now needs to be linked against gamecode even
though it never uses it.
o All instances of LIBADD/LDADD have a corresponding DEPENDENCIES
specificatiion.
o libraries now use a lib_ldflags macro to keep things consistent
o duplication of source/lib names has been minimized (particularly in
the libraries; more work needs to be done for the executables)
o automake spec blocks have been organized (again, more work needs to be
done for the executables)
The api hides all the gory details of message buffer setup and usage
(particularly the differences between writing and reading). Most
importantly, the api provides a safe way to read and write binary data
(always little endian).
This is an extension "wrapper" (no such C function). This allows ruamoko
programs to read property lists without worrying about the memory required
to store the string for the property list being read.
The plist code was written long before I thought of resource handles, and
then it was forgotten. This is much nicer and safer than storing C
pointers in progs memory space (*shudder*).
