54f2e417dc [ruamoko] Fix daft str_str abi 
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).

b7b8df0801 [ruamoko] Add str_lower builtin 
This returns a string with all chars lower-cased.

2bec2527b4 [gamecode] Re-expose PR_LoadStrings 
It's required for qfprogs now that PR_LoadDebug reads strings early.

59f48e5e32 [gamecode] Add function to test if string exists 
As it returns the string id, it is useful for getting an string id
without risking creating a new one.

7bcfd2f2be [gamecode] Move file_hash into debug resources 
I don't remember why I didn't do this earlier when I thread-safed progs.

c09f57c39e [gamecode] Delay .ctor calls if debugging 
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.

f90613bc3a [gamecode] Rename fields in pr_stack_t 
s and f are a little too succinct.

6b9d4a747d [ruamoko] Add a builtin to quote strings 
All unprintable chars are converted to either standard escape sequences
or \xHH.

535a2363bb [ruamoko] Create a va_copy for progs 
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.

7f86fb5529 [gamecode] Rework PR_Sprintf to use a state machine 
This makes it much easier to extend. There are even stubs for variable
field width and precision (not set yet).

a7956c7311 [gamecode] Move format state into a state struct 
This is the first step in reworking PR_Sprintf to use a state machine.
The goal is to make it more robust against errors and easier to extend
(eg, * width and precision).

58acc483fd [gamecode] Save new string ref in return slot 
This plugs the memory leak that caused qwaq to crash after resizing the
locals window a "few" times (several seconds of playing with the size).

e2d1a0f7d2 [ruamoko] Tag object memory with the class name

c23c68cf7f [ruamoko] Allow builtins to inc/dec retain count 
Needed for classes that are implemented entirely in C.

ddec80edc1 [qfcc] Make type encoding union anonymous 
I'd do more, but things get messy with direct access to unions that I
want to be anonymous.

8b1e4eea58 [qfcc] Bring back the core of type aliasing 
No aliasing is done yet, but most of the infrastructure is there again.

58ebbb147d [ruamoko] Add some new string builtins 
Wrappers for hold, valid and mutable. I have no idea why I didn't think
of wrapping string validation years ago.

ec82d6b027 [gamecode] Add support for holding ephemeral strings 
PR_HoldString converts ephemeral (temp and return) strings to dynamic
strings. This makes dealing with strings in progs a little easier.

b4874f7d9b [gamecode] Make PR_FreeString a little more forgiving 
It treats only strings that are actually invalid as invalid. That is,
now it is safe to "free" a static string: it's just a no-op.

2d5df34234 [gamecode] Add VM enter/exit events 
And rename prd_exit to prd_terminate (the idea is the host will
terminate the VM). This makes it possible for the debugger to pause the
VM before any code, even a builtin function, is executed. Breaks the
debugger source window, but only because it's not updating on file
change (I think).
 2020-03-26 12:30:32 +09:00
Bill Currie
1bd8e2ee85 [gamecode] Add a param pointer to debug_handler 
I decided I want events for VM enter/exit but enter needs to somehow
pass the function which will be executed (even if a builtin). A generic
void * param seemed the best idea, which meant the error string could be
passed via the param instead of a "global" string in the progs struct.

4cef9792f4 [util] Make hash-tables semi-thread-safe 
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.

0ad9f559ea [ruamoko] Move some string functions 
sprintf, vsprintf and strlen now in rua_strings, and strlen now returns
int like it should.

d867a1a9f1 [gamecode] Allow watch-point to be updated 
With the watch-point address cached in a local var, it was not possible
to update the watch-point while the progs were executing.

713150b41a [gamecode] Add debug hooks to the VM engine 
While there was a breakpoint hook, it was for only breakpoints and more
was needed. Now there's a generic hook that is called for tracing,
breakpoints, watch points, runtime errors and VM errors, with the
"event" type passed as the first parameter and a data pointer in the
second.

1d6843d7f0 [gamecode] Improve watchpoint handling a little 
Mostly just update the old value if the condition didn't trigger.

Bill Currie
753d183d82 [gamecode] Be more informative with function calls 
PR_EnterFunction and PR_LeaveFunction now print the
entered/left/returned function when tracing. Makes debugging obj code
much easier.

a9c6974fc7 [audio] Quieten jack about xruns 
They messages are annoying at the moment, but I will want them when I
get around to chasing down the root cause, so hidden behind a developer
mask.

28f50d2719 Add function key defs up to F48 
This allows for the four combinations of shift and control. Not
bothering with alt because alt-f4 closes my xterm (bbkeys from the looks
of it: it grabs a bunch of Mod1-* keys).
