- Use nullness checks when calling weakly linked functions.
- Avoid typedef for reasons described in Linux Kernel style guide.
- Avoid enum in in Windows headers. Earlier in Cosmo's history all one
hundred files in libc/nt/enum/ used to be enums and it resulted in
gigabytes of DWARF data almost as large as everything else in the
codebase combined.
- Bitfields aren't our friends. They have frequent ABI breakages,
inconsistent arithmetic across compilers, and different endianness
between cpus. Compiler authors also haven't invested much roi into
making bit fields go fast so they produce poor assembly.
- Use memccpy() instead of strncpy() or snprintf() for length-bounded
copying of C strings. strncpy() is a misunderstood function and
snprintf() is awesome but memccpy() deserves more love.
- SIOCGIFCONFIG: reads and enumerate all the network interfaces
- SIOCGIFADDR: reads network address for a given interface
- SIOCGIFFLAGS: reads network flags for a given interface
- SIOCGIFNETMASK: reads network netmask for a given interface
- SIOCGIFBRDADDR: reads network broadcast address for a given interface
- SIOCGIFDSTADDR: reads peer destination address for a given
interface (not supported for Windows)
This change defines Linux ABI structs for the above interfaces and adds
polyfills to ensure they behave consistently on XNU and Windows.
- Get ASAN working on Windows.
- Deleting directories and then recreating them with the same name in a
short period of time appears to be a no-no on Windows.
- There's no reason to call FlushFileBuffers on close() for pipes, and
it's harmful since it might block indefinitely for no good reason.
For the first time ever, all tests in this codebase now pass, when
run automatically on macos, freebsd, openbsd, rhel5, rhel7, alpine
and windows via the network using the runit and runitd build tools
- Fix vfork exec path etc.
- Add XNU opendir() support
- Add OpenBSD opendir() support
- Add Linux history to syscalls.sh
- Use copy_file_range on FreeBSD 13+
- Fix system calls with 7+ arguments
- Fix Windows with greater than 16 FDs
- Fix RUNIT.COM and RUNITD.COM flakiness
- Fix OpenBSD munmap() when files are mapped
- Fix long double so it's actually long on Windows
- Fix OpenBSD truncate() and ftruncate() thunk typo
- Let Windows fcntl() be used on socket files descriptors
- Fix Windows fstat() which had an accidental printf statement
- Fix RHEL5 CLOCK_MONOTONIC by not aliasing to CLOCK_MONOTONIC_RAW
This is wonderful. I never could have dreamed it would be possible
to get it working so well on so many platforms with tiny binaries.
Fixes#31Fixes#25Fixes#14
It turned out that the linker was doing the wrong with the amalgamation
library concerning weak stubs. A regression test has been added and new
binaries have been uploaded to https://justine.lol/cosmopolitan/
Ideally this should be fixed by building a tool that turns multiple .a
files into a single .a file with deduplication. As a workaround for now
the cosmopolitan.a build is restructured to not include LIBC_STUBS which
meant technical debt needed to be paid off where non-stub interfaces
were moved to LIBC_INTRIN and LIBC_NEXGEN32E.
Thank @PerfectProductions in #31 for the report!
This change pays off technical debt with the function -> DLL mappings in
libc/nt/master.sh, which was originally defined based on binary analysis
on Windows 10. It's now been updated so the kernel32/kernelbase/advapi32
imports should be exactly as they are written, on the MSDN documentation
and that wouldn't have been easy without Geoff Chappell's work thank him
