There's no point in zeroing out memory that is only going to be
overwritten by the loaded file (excess bytes beyond the end of a
massaged text file shouldn't be accessed anyway, and the terminating
null is still written).
This is needed for cleaning up excess memsets when loading files because
Hunk_RawAllocName has nonnull on its hunk pointer (as the rest of the
hunk functions really should, but not just yet).
For now, the functions check for a null hunk pointer and use the global
hunk (initialized via Memory_Init) if necessary. However, Hunk_Init is
available (and used by Memory_Init) to create a hunk from any arbitrary
memory block. So long as that block is 64-byte aligned, allocations
within the hunk will remain 64-byte aligned.
Still "some" more to go: a pile to do with transforms and temporary
entities, and a nasty one with host_cbuf. There's also all the static
block-alloc lists :/
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.
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 fixes the problem of not finding files without a .gz extension when
gzip support is enabled (most of my quake data is compressed, so it took a
while for me to notice the problem).
_QFS_VOpenFile is actually _QFS_FOpenFile reimplemented to take vpath start
and end parameters so the search can be limited. QFS_VOpenFile,
_QFS_FOpenFile, and QFS_FOpenFile are all wrappers for _QFS_VOpenFile.
A vpath is the union of all locations searched for a file in a single
gamedir (eg, shadows, id1 etc). This is a necessary step to preventing
problems like id1/maps/start.lit being used for shadows/maps/start.bsp.
However, QFS_FilelistFill still needs to be reworked as it does not compile
yet (testing was done with a gutted QFS_FilelistFill).
Buffer underflow and though strcpy has always been safe there, change to
memmove. Had the added benefit of helping me create more test cases for
better coverage.
Yay, Deek for finding another bug in qf :). He had an old dirconf that
didn't specify HudType and thus caused the status bar code to blow up. Set
the default to "id" if none is found.
I have no idea why I did that, but it crept in with the var substitution
fix, so I guess it might have been an attempt to fix a bug, but it looks
like it was broken anyway.
Currently only "id", "hipnotic" and "rogue" are supported (anything else is
treated as "id"). Has no effect in quakeworld (good thing too: changing
gamedirs is a little broken).
