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).

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.

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.

4a61ff0d35 [util] Switch to using sigaction for signal handling

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).

0cbe438ac1 [util] Make va slight robust against chained use 
va now cycles through a set of four dstrings rather than using just the
one. This allows for some simple chaining of va usage.

3d62a7f253 [gamecode] Use fuzzy bsearch to find defs by address 
The idea is to find th def that contains the address. Had to write my
own bsearch (well... lifted from wikipedia) because libc's is exact. The
defs are assumed to be sorted (which qfcc now ensures when it writes
progs and sym files).
