- 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
Status lines for Emacs and Vim have been added to Python sources so
they'll be easier to edit using Python's preferred coding style.
Some DNS helper functions have been broken up into multiple files. It's
nice to have one function per file whenever possible, since that way we
don't need -ffunction-sections. Another reason it's good to have small
source files, is because the build will be enforcing resource limits on
compilation and testing soon.
The implementations of the getproto* functions follow from the getserv*
functions: same static name allocation, same type of internal function
that opens a file to search, aliases are not written to the struct, same
type of error handling/returns.
This changes also fixes a getaddrinfo AI_PASSIVE memory error. When
getaddrinfo is passed name = NULL and AI_PASSIVE in hints->ai_flags, it was
setting the s_addr value to INADDR_ANY but *not* returning the addrinfo
pointer via *res = ai. This caused a free(NULL) memory error when the caller
tried to free res, because the caller expects res to be a valid pointer to a
struct addrinfo.
Our non-standard API parseport() has been updated to use strtoimax.
strtoimax has an extra parameter endptr to store where the parsing was
terminated. endptr is used in parseport to check if the provided string
was valid.
