- 10.5% reduction of o//depend dependency graph
- 8.8% reduction in latency of make command
- Fix issue with temporary file cleanup
There's a new -w option in compile.com that turns off the recent
Landlock output path workaround for "good commands" which do not
unlink() the output file like GNU tooling does.
Our new GNU Make unveil sandboxing appears to have zero overhead
in the grand scheme of things. Full builds are pretty fast since
the only thing that's actually slowed us down is probably libcxx
make -j16 MODE=rel
RL: took 85,732,063µs wall time
RL: ballooned to 323,612kb in size
RL: needed 828,560,521µs cpu (11% kernel)
RL: caused 39,080,670 page faults (99% memcpy)
RL: 350,073 context switches (72% consensual)
RL: performed 0 reads and 11,494,960 write i/o operations
pledge() and unveil() no longer consider ENOSYS to be an error.
These functions have also been added to Python's cosmo module.
This change also removes some WIN32 APIs and System Five magnums
which we're not using and it's doubtful anyone else would be too

DESCRIPTION
The UNIX unzip command, courtesy of the Info-ZIP project.
PROVENANCE
unzip610b.zip (circa 2010)
https://sourceforge.net/projects/infozip/files/unreleased%20Betas/UnZip%20betas/
LICENSE
BSD-like with Apache-like requirement that changes be documented.
LOCAL CHANGES
The only way this software differs from the normal InfoZIP sources is
that we're linking the Cosmopolitan C Library, which enables it to be
built as an Actually Portable Executable.
Minor changes include:
- Normalization of header / build config for platform / repository
sed -i -e '/# *include *<.*/d' *.*
sed -i -e 's!# *include *"!#include "third_party/unzip/!' *.*
sed -i -e '1 i\// clang-format off' *.c *.h
- Fixed a lot of static analysis buffer overflow warnings.
