This change fixes Cosmopolitan so it has fewer opinions about compiler
warnings. The whole repository had to be cleaned up to be buildable in
-Werror -Wall mode. This lets us benefit from things like strict const
checking. Some actual bugs might have been caught too.
- Introduce ualarm() function
- Make rename() report EISEMPTY on Windows
- Always raise EINVAL upon open(O_RDONLY|O_TRUNC)
- Add macro so ./configure will detect SOCK_CLOEXEC
- Fix O_TRUNC without O_CREAT not working on Windows
- Let fcntl(F_SETFL) change O_APPEND status on Windows
- Make sure pwrite() / pread() report ESPIPE on sockets
- Raise ESPIPE on Windows when pwrite() is used on pipe
- Properly compute O_APPEND CreateFile() flags on Windows
- Don't require O_DIRECTORY to open directories on Windows
- Fix more instances of Windows reporting EISDIR and ENOTDIR
- Normalize EFTYPE and EMLINK to ELOOP on NetBSD and FreeBSD
- Make unlink() / rmdir() work on read-only files on Windows
- Validate UTF-8 on Windows paths to fix bug with overlong NUL
- Always print signal name to stderr when crashing due to SIG_DFL
- Fix Windows bug where denormalized paths >260 chars didn't work
- Block signals on BSDs when thread exits before trashing its own stack
This way complex runtime features (e.g. ftrace, symbol tables) can
always yoink zipos support. This is important now that apelink.com
automates embedding symbol tables for multiple cpus.
This change ports APE Loader to Linux AARCH64, so that Raspberry Pi
users can run programs like redbean, without the executable needing
to modify itself. Progress has also slipped into this change on the
issue of making progress better conforming to user expectations and
industry standards regarding which symbols we're allowed to declare
- 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 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
- Fix unused local variable errors
- Remove yoinks from sigaction() header
- Add nox87 and aarch64 to github actions
- Fix cosmocc -fportcosmo in linking mode
- It's now possible to build `make m=llvm o/llvm/libc`
- compile.com now polyfills -march=native which gcc/clang removed
- Guarantee zero Windows code is linked into non-Windows binaries
- MODE=tinylinux binaries are now back to being as tiny as ~4kb
- Improve the runtime's stack allocation / alignment hack
- GitHub Actions now tests Linux modes for assurance
- 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
This change implements a new approach to function call logging, that's
based on the GCC flag: -fpatchable-function-entry. Read the commentary
in build/config.mk to learn how it works.
- Utilities like pledge.com now build

- *NSYNC cancellations now work on Windows
- Support closefrom() on NetBSD
* Proof of concept of sqlite serialization
This is a minimal proof of concept in order to show that it is easily possible to store the sqlite database within the zip file itself not requiring creating an external file first. Changes include compiling the sqlite library with the serialization flag, adding serialize/deserialize to the lua sqlite library and demonstrating the work via the redbean demo.
* Change demo for sqlite serialization
As explained in https://github.com/jart/cosmopolitan/pull/436#issuecomment-1164706893 the original use case is not possible with sqlite serialization, as an in-memory database cannot be shared across multiple processes. Thereby, this use case simply creates a backup of the in-memory database created in '.init.lua' and loads it to do a query.
* Fix sqlite3_deserialize parameters
The call to the sqlite3 library for the deserilization wasn't fully correct. This should fix the size parameters.
It can now handle 240k SQLite write QPS at 3ms 99 percentile latency.
We're still working out the kinks since it's brand new. But we've got
this running in production already!
- Fix preadv() and pwritev() for old distros
- Introduce _npassert() and _unassert() macros
- Prove that file locks work properly on Windows
- Support fcntl(F_DUPFD_CLOEXEC) on more systems
This change restores the .symtab symbol table files in our flagship
programs (e.g. redbean.com, python.com) needed to show backtraces. This
also rolls back earlier changes to zip.com w.r.t. temp directories since
the right way to do it turned out to be the -b DIR flag.
This change also improves the performance of zip.com. It turned out
mmap() wasn't being used, because zip.com was assuming a 4096-byte
granularity, but cosmo requires 65536. There was also a chance to speed
up stdio scanning using the unlocked functions.
- 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 Landlock Make so that only the output target file is
unveiled, rather than unveiling the directory that contains it. This
gives us a much stronger sandbox. It also helped identify problematic
build code in our repo that should have been using o/tmp instead.
Landlock isn't able to let us unveil files that don't exist. Even if
they do, then once a file is deleted, the sandboxing for it goes away.
This caused problems for Landlock Make because tools like GNU LD will
repeatedly delete and recreate the output file. This change uses the
compile.com wrapper to ensure on changes happen to the output inode.

This change turns symbol table compression back on using Puff, which
noticeably reduces the size of programs like redbean and Python. The
redbean web server receives some minor API additions for controlling
things like SSL in addition to filling gaps in the documentation.
This change introduces a `-W /dev/pts/1` flag to redbean. What it does
is use the mincore() system call to create a dual-screen terminal
display that lets you troubleshoot the virtual address space. This is
useful since page faults are an important thing to consider when using a
forking web server. Now we have a colorful visualization of which pages
are going to fault and which ones are resident in memory.
The memory monitor, if enabled, spawns as a thread that just outputs
ANSI codes to the second terminal in a loop. In order to make this
happen using the new clone() polyfill, stdio is now thread safe.
This change also introduces some new demo pages to redbean. It also
polishes the demos we already have, to look a bit nicer and more
presentable for the upcoming release, with better explanations too.
You now have some ability to truly make an executable yours, by adding a
`.args` file to the root of the zip structure. If this is specified,
then you'll be overriding the default CLI args.
This will be a great feature for folks who want to distribute their own
apps, using the interpreter executable, but have the executable appears
to be just your app rather than being the interpreter.
