GIB. Added some breakpoint GIB builtins for debugging script/intepreter
interactions. Made carne work properly again (local variables don't
disappear in interactive mode)
of leaf names in a stem variable via %var, the builtin functions 'count'
and 'contains', and an initial interface between qw-server and GIB to allow
querying of clients and their info strings. Also cleaned up the chat event
interface a bit. Renamed a few builtins.
changes. There still remains some bugs to be squashed, a feature or two to
add, and some polishing to be done. However, it seems to be in a workable
state.
All the details of game directories will be fully configurable (search
paths and gamecode file name currently supported). Downloading of skins to
qw/skins only currently broken (will download to $gamedir/skins for now).
interpreter struct so that custom cbuf data can be reset after an error.
This fixes a bug where GIB would think it was still waiting for a return
value after an error occurred in an embedded command.
below, or relative above (uses .. to ascend the filesystem). Changed
file functions in GIB to use this. GIB can now be initialized in a
non-sandboxed mode, which at the moment means that GIB scripts run with
carne can access the entire filesystem.
to accommodate it. Added the strict flag to cbufs, which causes an error
to be generated when a command is not found instead of just warning the
user. GIB buffers have the strict flag set by default.
handle SIGFPE and allow the registered signal handler to do recovery

a little cleaning and commenting in gib_parse.c. Added support for \t

also create davsprintf and dasprintf to /append/ the printed strings to the
dstring rather than overwriting it as is done with dvsprintf and dsprintf.
methods directly or setup the progs struct for a normal function call to
call a progs method rather than recursively calling PR_ExecuteProgram. This
will reduce method call overhead (both cpu and stack usage), fix the loss
of tracing when calling a method and makes it possible to break out of the
progs engine simply if threaded progs are ever implemented.
This prevents var substitution from being performed on the return value
of a function. The local variable ifs can now be set to specify a custom
field separator for use in for loops. file.find will also insert ifs
between file names instead of a space if it is set. file.find will also
no longer put . and .. in a list of file names.

The player global branch variable is now updated with useful information
and the location.get builtin is available to return the current location
of the player based on loc files. Fixed a bug with zooming out in zoom.gib.

make progs segfault handling much more robust (and general: sigill etc too:)
functions out of bi_inputline.c. now somebody can be insane enough to
implement a qc controled console for the server ;) (more importantly, one
step closer to being able to have the server link with libQFcsqc (hah!))
Calculate radius for alias models as well as brush.
Culling is no longer optional on alias models (was only ever disabled for viewmodel, which is a lot of extra effort to avoid clip testing 1 thing out of hundreds).
Clip QSG2 scaled alias models with a scaled bbox.
to prevent conflicts with math expressions. All clients and servers are set
to create buffers with the normal parser. However, scripts ending in .gib
are now executed in a GIB buffer, and the export command can be used to
make specific GIB functions available to normal command buffers (i.e. the
console).

preparation of separating GIB into its own module. Command-related
functions will stay in util, but the buffer handling code and interpreter
will be moved out of cmd.c.
With any luck it should actually work this time. Added the getimpulse
command so that GIB scripts can check if an impulse command is pending
before sending their own. Fixed all the memory leaks I could find.
QuakeC and GIB seem to be clean except for maybe one or two sneaky leaks
I can't track down.
This allows Cmd_Return_f to decide which buffer it should return a value
to. End result: you can put blocks of code with a return statement inside
an embedded command statement. I hope nobody minded me using my
quakeforge.net account to code a bit :P
to start. More will follow. Switched to doubles from floats and allowed
numbers with exponents to be parsed properly. Also changed the number of
significant digits printed to 10. Changed fov so it is now capped at 1,
not 10. The float value of fov is now used instead of int, so more
precision can be attained at small values.
a static `stack') to avoid the function call overhead. this cuts about 40%
of the execution time from this function.
No matter what I tried, best results were obtained using __builtin_expect,
so make sure non-gcc compilers do the right thing when they encounter it.
Cmd_TokenizeString since I realized the code was just pulling it apart and
putting it back together. Added Cmd_Argsu to access the unprocessed
command. Added support for else following if in such a way that
if/else if/else structures work. Added support for unary operators in
EXP and added the ! (not) operator. The ifnot command will be kept
for variety.
to GIB. Fixed a bug in dstring_replace that was causing too much data to
be copied when the incoming string was larger than what was being replaced.
Very minor reorganization in cmd.c (1 function moved around I think).
cmd.c should probably get broken up into separate files soon.
add dstring_replace. this replaces a string of lenth rlen at position
pos with data of lenth len, growing, shrinking and shuffling data as
appropriate. At this rate, the dstring `class' will get buffer gap
editing capabilities :)
cmd.c:
Cmd_TokenizeString builds cmd_active_buffer->line again.
Cmd_Process bails out instantly if cmd_active_buffer is a legacy buffer
and uses dstring_replace to modify the parameters in
cmd_active_buffer->line. This last change results in drastic
simplification (and accuracy) of the commandline reconstruction code,
both in Cmd_TokenizeString and Cmd_Process.
1) when /not/ building static plugins, the plugin info name is, once again,
PluginInfo, but is still type_name_PluginInfo for static plugins. This
allows plugins to be symlinked (highly desirable for the debian packages,
and likely others). This also requires plugins to /not/ be loaded with
RTLD_GLOBAL.
2) because of 1, snd_alsa_0_9 has to explicitly load libasound itself. This
just happens to fix my segfault on shutdown in RedHat 6.2.
handled, meaning that execution can be paused at any time without a hitch.
Warning: This is a major change to the architecture (or lack thereof) of
GIB. Please test for bugs! Also, there are a few ugly bits of code that
need to be cleaned up, but that work for now.
support for BSP models, until they can be fixed. gl_multitexture should now
actually be a speedup!
NOTE: Some OpenGL implementations have trouble with the texture function
used. 3Dfx Voodoo 1/2 are known to have this trouble. I don't know how to fix
this, or even if it can be fixed. :/
This means things like echo ~{somefunc arg1 arg2} will get parsed properly
without having to enclose it in quotes. Exported the Cmd_Return function
so that anything can return values to GIB (such as quakec).
structure to help tidy the command buffer struct up a bit, fixed a few
bugs and probably created 100 more. A lot of things were changed to
allow embedded commands:
- Old buffers on the stack are left alone for Cbuf_ExecuteStack to
clean up. This is so return values can be extracted from them.
- The imperative flag has been added. An imperative buffer and all buffers
following it can not be paused with the wait command.
- The returning flag and retval dstring have been added. If a buffer
returned something, the flag will be set.
- The return command was added so there was something to use in the
substitution. Return nukes all loop buffers since they don't really count
as independent functions, sets the return value on the top buffer, and
clears it.
- Who knows what else.
now recycled, not freed. Fixed some bugs in exp.c. Ready to add embeded
functions (read: function calls with return values) and for loops.
Probably some other misc. fixes, I tend to go on debugging streaks.
Made variable substitution recursive, so ${${foo}} will be the value of
the variable whose name is contained in foo. Added setl command to
manipulate local variables. The only other place they can be used is in
variable substitution.
buffers to be linked into execution stacks and changed aliases and script
files to be run in a new stack frame. Cbuf_Execute executes the stack from
the top down, so wait commands are handled properly.
within braces, and put support for comments back in (oops). To use math
evaluation, put a math expression inside $(). If you have spaces in your
expression, you'll need to enclose the entire thing in quotes so it doesn't
get split up into multiple tokens.
Changed Cmd_TokenizeString to accept a flag that controls the application
of filters (tags, variables, escape characters) to the tokens and modified
a few places in the source that called it. Added a secondary command
buffer that is parsed without filters for legacy command support.
Currently, it is only used for commands stuffed into the console from the
server. It is hacky, and I hope to eventually generalize the console
interface to support any number of buffers and audit the rest of the code
to recognize it. For now, the legacy buffer at least keeps escape
character parsing from destroying info strings.
console command parser. It will eventually include html-like tags for
modifying text (gold numbers, brown characters, etc) and escaped characters.
The major differences so far are that dynamic strings are now used instead
of static buffers, and single quotes can be used to enclose tokens as
well as double quotes.

like normal, f_skins reports the average percent fullbright for all loaded
skins, and f_skins skinname reports the fullbright percent for a signle
skin. cl_freply controls the time in seconds before another query can be
made. Set it to 0 to disable them. More queries will be added later.
The table for accessing special characters from the console has been
tweaked a bit. Expect it to get tweaked more in the future.
This required changes to the api (info_t instead of char *) but should be
a net gain in speed (not a lot, admittedly: it was pretty fast to begin
with, but this paves the way for some other changes I have in mind).

give mst_t a buffer to hold unterminated message strings
kill MSG_ReadStaticString and MSG_ReadStringLine
msg.c:
kill MSG_ReadStaticString and MSG_ReadStringLine
MSG_ReadString: implement the buffer for unterminated message strings
and update readcount on badread
cl_main.c:
go back to MSG_ReadString and fix up the resulting const char * issues
cl_parse.c:
rewrite the cl_mofake code all because of an uninitialized variable :)
sv_main.c:
use MSG_ReadString instead of MSG_ReadStringLine because
Cmd_TokenizeString really doesn't care about a terminating \n
directly into the packet data.
- change a bunch of char *'s to const char *'s for the above. Only
thing that had trouble was the cl_nofake handler, which I changed to
use a local buffer.
- add MSG_ReadStaticString which acts like the old MSG_ReadString,
specifically that it uses a static buffer and tollerates
unterminated strings.
- add a Q_strnlen function, and make strnlen use it if strnlen is
undefined.
- Add a net_svc.h and net_svc.c which will preparse svc messages into
structs, for easier handling. Currently only soundlist and
modellist are done.
segfault if your first call was with "". Probably could cause
crashes too
- add a string.c file to libQFutil, with a Q_strcasestr function,
which strcasestr is defined to if it's not already defined. (we'd
get that with glibc if we defined __USE_GNU, but we don't)
- make client_t and SV_ExtractFromUserinfo both use NAME_MAX for
their name arrays, instead of 32 for one and 80 for the other
- rewrite almost all of SV_ExtractFromUserinfo's name handling.
- \r, \n, and \t are all converted to spaces
- leading/trailing spaces are stripped
- consecutive spaces are reduced to a single space
- empty names are considered bad
- user-* nicks are considered bad (unless forced to them)
- a name containing console or admin is considered bad
- a name that already exists is considered bad
- if they have a bad name it gets forced to user-%d, where %d is
their userid
- netname in the progs is now updated properly
- name changes are always reported unless it's the initial setting,
rather than only if they're full connected and not a spectator
- finally, if the name change fails (info string exceeded), give
them the boot. (before this was only done for duplicate names)
That's about it :)
of pre-registered (Sys_RegisterShutdown) function before actually exiting
the program. This should take care of the pain when an ncurses server

- switch some prints over NUM_FOR_BAD_EDICT
- change NUM_FOR_EDICT to call PR_RunError on error, instead of
PR_Error. That was it prints out a backtrace.
(I did it in reverse order ;)
(Sys_DPrintf is new) is now used exclusively for all lib printing. Con_Init
sets the sys printf recirection to Con_Print (which has been revamped
appropriatly) and the server sets it to SV_Print (which was SV_Printf and
the new SV_Printf calls /it/). This should fix the rcon print redirection
issues.
