- This commit mints a new release of APE Loader v1.2 which supports
loading ELF programs with a non-contiguous virtual address layout
even though we've never been able to take advantage of it, due to
how `objcopy -SO binary` fills any holes left by PT_LOAD. This'll
change soon, since we'll have a new way of creating APE binaries.
- The undiamonding trick with our ioctl() implementation is removed
since POSIX has been killing ioctl() for years and they've done a
much better job. One problem it resolves, is that ioctl(FIONREAD)
wasn't working earlier and that caused issues when building Emacs
- 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
This change fixes a regression in unix.connect() caused by the recent
addition of UNIX domain sockets. The BSD finger command has been added
to third_party for fun and profit. A new demo has been added to redbean
showing how a protocol as simple as finger can be implemented.
