Cosmopolitan now supports 104 time zones. They're embedded inside any
binary that links the localtime() function. Doing so adds about 100kb
to the binary size. This change also gets time zones working properly
on Windows for the first time. It's not needed to have /etc/localtime
exist on Windows, since we can get this information from WIN32. We're
also now updated to the latest version of Paul Eggert's TZ library.
- tcgetpgrp(STDIN_FILENO) should be equal to getpgrp() on Windows also,
found while reading wget source code which uses this check to decide
whether to print to stderr or to a file
- IN6_ADDR_ARE_EQUAL is a comparison macro used when IPV6 is allowed,
found while reading CPython3.11 source code
- the changes in signal.h and addition of ucontext.h are because
CPython3.11 source code expect sigaltstack to be available
- the sqlite3.mk change is because CPython3.11 requires sqlite3 to be
built with -DOMIT_SHARED_CACHE
- unistd.h has getopt.h now, because some libraries like it there
This change figures out some of the build configuration issues we've
been having with libcxx. The c++ span header is added. Per a Discord
discussion we're now turning off `-g` for the default build mode, so
consider using `make MODE=dbg` or `make MODE=zero` for GDB debugging
which works much better than `MODE=` ever has. Note that the default
build mode has always had very good function call / system call logs
plus you can still use ShowCrashReports() for backtrace. Making this
change ensures cosmocc will better conform to FOSS norms. Lastly the
LoadZipArgs() API has been added to cosmopolitan.a and <cosmo.h>.
- Found some bugs in LLVM compiler-rt library
- The useless LIBC_STUBS package is now deleted
- Improve the overflow checking story even further
- Get chibicc tests working in MODE=dbg mode again
- The libc/isystem/ headers now have correctly named guards
- SQLite file locking now works on Windows
- SQLite will now use fdatasync() on non-Apple platforms
- Fix Ctrl-C handler on Windows to not crash with TLS
- Signals now work in multithreaded apps on Windows
- fcntl() will now accurately report EINVAL errors
- fcntl() now has excellent --strace logging
- Token bucket replenish now go 100x faster
- *NSYNC cancellations now work on Windows
- Support closefrom() on NetBSD
This change addresses various open source compatibility issues, so that
we pass 313/411 of the tests in https://github.com/jart/libc-test where
earlier today we were passing about 30/411 of them, due to header toil.
Please note that Glibc only passes 341/411 so 313 today is pretty good!
- Make the conformance of libc/isystem/ headers nearly perfect
- Import more of the remaining math library routines from Musl
- Fix inconsistencies with type signatures of calls like umask
- Write tests for getpriority/setpriority which work great now
- conform to `struct sockaddr *` on remaining socket functions
- Import a bunch of uninteresting stdlib functions e.g. rand48
- Introduce readdir_r, scandir, pthread_kill, sigsetjmp, etc..
Follow the instructions in our `tool/scripts/cosmocc` toolchain to run
these tests yourself. You use `make CC=cosmocc` on the test repository
A new rollup tool now exists for flattening out the headers in a way
that works better for our purposes than cpp. A lot of the API clutter
has been removed. APIs that aren't a sure thing in terms of general
recommendation are now marked internal.
There's now a smoke test for the amalgamation archive and gigantic
header file. So we can now guarantee you can use this project on the
easiest difficulty setting without the gigantic repository.
