This commit makes numerous refinements to cosmopolitan memory handling.
The default stack size has been reduced from 2mb to 128kb. A new macro
is now provided so you can easily reconfigure the stack size to be any
value you want. Work around the breaking change by adding to your main:
STATIC_STACK_SIZE(0x00200000); // 2mb stack
If you're not sure how much stack you need, then you can use:
STATIC_YOINK("stack_usage_logging");
After which you can `sort -nr o/$MODE/stack.log`. Based on the unit test
suite, nothing in the Cosmopolitan repository (except for Python) needs
a stack size greater than 30kb. There are also new macros for detecting
the size and address of the stack at runtime, e.g. GetStackAddr(). We
also now support sigaltstack() so if you want to see nice looking crash
reports whenever a stack overflow happens, you can put this in main():
ShowCrashReports();
Under `make MODE=dbg` and `make MODE=asan` the unit testing framework
will now automatically print backtraces of memory allocations when
things like memory leaks happen. Bugs are now fixed in ASAN global
variable overrun detection. The memtrack and asan runtimes also handle
edge cases now. The new tools helped to identify a few memory leaks,
which are fixed by this change.
This change should fix an issue reported in #288 with ARG_MAX limits.
Fixing this doubled the performance of MKDEPS.COM and AR.COM yet again.

# UNSPECIFIED PREREQUISITES TUTORIAL
|
|
#
|
|
# A build rule must exist for all files that make needs to consider in
|
|
# order to build the requested goal. That includes input source files,
|
|
# even if the rule is empty and does nothing. Otherwise, the .DEFAULT
|
|
# rule gets triggered.
|
|
#
|
|
# This is a normal and neecssary behavior when source files get deleted.
|
|
# The build reacts automatically to this happening, by simply deleting
|
|
# and regenerating the dependency graph; so we can safely use wildcard.
|
|
#
|
|
# This is abnormal if it needs to keep doing that repeatedly. That can
|
|
# only mean the build config is broken.
|
|
#
|
|
# Also note that a suboptimal in-between state may exist, where running
|
|
# `make -pn` reveals rules being generated with the .DEFAULT target, but
|
|
# never get executed since they're not members of the transitive closure
|
|
# of `make all`. In that case the build config could be improved.
