We now rewrite the binary image at runtime on Windows and XNU to change
mov %fs:0,%reg instructions to use %gs instead. There's also simpler
threading API introduced by this change and it's called _spawn() and
_join(), which has replaced most clone() usage.
Our build was flaking due to ETXTBSY errors running multiple redbean
instances in parallel. This is due to the StoreAsset() support which
seems to cause enough problems it's worth making a *breaking change*
turning it off by default for now. There's a new -* flag, to restore
redbean's old self-modifying behavior.
- Fix DescribeSigset()
- Introduce new unix.rmrf() API
- Fix redbean sigaction() doc example code
- Fix unix.sigaction() w/ more than two args
- Improve redbean re module API (non-breaking)
- Enhance Lua with Python string multiplication
- Make third parameter of unix.socket() default to 0
The Compress() and Uncompress() APIs were a mistake. The functions
themselves work fine, but it's a design blemish and does superfluous
work. Since they were only introduced in the last few weeks, they're now
deprecated and references to them have been scrubbed from the website
and other documentation. Please use the new APIs since the old APIs will
be removed at some point in the future.
This change introduces automated Lua unit tests for the Redbean APIs.
There's a few functions that were broken which have now been fixed, e.g.
Underlong() and Decimate().
- Wrap clock_getres()
- Wrap sched_setscheduler()
- Make sleep() api conformant
- Polyfill sleep() using select()
- Improve clock_gettime() polyfill
- Make nanosleep() POSIX conformant
- Slightly improve some DNS functions
- Further strengthen pledge() sandboxing
- Improve rounding of timeval / timespec
- Allow layering of pledge() calls on Linux
- Polyfill sched_yield() using select() on XNU
- Delete more system constants we probably don't need
- Introduce __assert_disable global
- Improve strsignal() thread safety
- Make system call tracing thread safe
- Fix SO_RCVTIMEO / SO_SNDTIMEO on Windows
- Refactor DescribeFoo() functions into one place
- Fix fork() on Windows when TLS and MAP_STACK exist
- Round upwards in setsockopt(SO_RCVTIMEO) on Windows
- Disable futexes on OpenBSD which seem extremely broken
- Implement a better kludge for monotonic time on Windows
P had the same assignment as F. This is now fixed so that it is
possible to increase RLIMIT_NPROC (e.g. when trying to build
on system accounts with more than 1024 processes running).
This will help make it easier to troubleshoot ABI breakages with on
operating systems that, unlike Linux don't have ironclad guarantees
to not break userspace.
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.
This should strike a better compromise that keeps people happy about the
security of APE when it extracts the loader. This way systems with users
who aren't trusted (e.g. CPanel) won't be at any risk of compromise when
there isn't an `ape` loader on the system `$PATH`.
This change also bumps redbean up to 2.0.3
This change hardens the code for opening /zip/ files using the system
call interface. Thread safety and signal safety has been improved for
file descriptors in general. We now document fixed addresses that are
needed for low level allocations.
- Fix Makefile flaking due to ZIPOBJ_FLAGS generation
- Make printf() floating point and gdtoa thread safe
- Polish up the runit / runitd programs some more
- Prune some more makefile dependencies
These releases are really exciting since they contained the patches we
worked to get upstreamed. It means that their /bin/sh interpreters all
work fine with Actually Portable Executable now.
This change switches most of the core locks to be re-entrant, in order
to reduce the chance of deadlocking code that does, clever things with
asynchronous signal handlers. This change implements it it in pthreads
so we're one step closer to having a standardized threading primitives
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 also fixes a bug in the argon2 module, where the NUL
terminator was being included in the hash encoded ascii string. This
shouldn't require any database migrations to folks who found this module
and productionized it, since the argon2 library treats it as a c string.

If you checked out yesterday's APE commit, please run:
rm -f /usr/bin/ape o/tmp/ape /tmp/ape "${TMPDIR:-/tmp}/ape"
Because this change fixes certain aspects of the new ABI. We don't have
automated migrations for APE loader versions yet. Thanks! You can also
download prebuilt binaries here:
- https://justine.lol/ape.elf (Linux/FreeBSD/NetBSD/OpenBSD)
- https://justine.lol/ape.macho (Apple)
Install the appropriate one as `/usr/bin/ape`.

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.
These will now be included in the cosmopolitan.a releases. It took a bit
of time because, these functions depend on heavyweight parts of the libc
that wouldn't be appropriate for the core zlib library to depend upon.
Fixes#345
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.

This change makes strftime() go faster and makes it possible to format
timestamps through the big bang to most of the stelliferous era. India
has also been added as a timezone to most binaries. Since we were able
to change the struct tm abi, this makes cosmopolitan libc superior, to
just about everything else, when it comes to standing the test of time

It's now possible to pass the `-S` or `-SS` flags to sandbox redbean
worker proecsses after they've been forked. The first `-S` flag is
intended to be a permissive builtin policy that limits system calls to
only that which the various parts of redbean serving need. The second
`-SS` flag is intended to be more restrictive, preventing things like
the Lua extensions you download off the web from using the HTTP client
or sockets APIs. In upcoming changes you'll be able to implement your
own Berkeley Packet Filter sandbox programs and load them via Lua.
- Fix a regression with the previous change that broke redbean
- Add chroot(), resource limit, seccomp, and other stuff to redbean
- Write lots and lots of documentation
- Iron out more system call issues
You can now interact with the global web server state on the command
line, which the web server is running. This supports Emacs shortcuts
with history, readline parity, <tab> completions, plus hints. Enjoy!
This change makes further effort towards improving our poll()
implementation on the New Technology. The stdin worker didn't work out
so well for Python so it's not being used for now. System call tracing
with the --strace flag should now be less noisy now on Windows unless
you modify the strace.internal.h defines to turn on some optional ones
that are most useful for debugging the system call wrappers.

- You can now poll() files and sockets at the same time on NT
- Fix bug in appendr() that manifests with dlmalloc footers off
You can now call functions like fork() from Lua and it'll work across
all supported platforms, including Windows. This gives you a level of
control of the system that Lua traditionally hasn't been able to have
due to its focus on old portable stdio rather modern POSIX APIs. Demo
code has been added to redbean-demo.com to show how it works.
This change also modifies Lua so that integer literals with a leading
zero will be interpreted as octal. That should help avoid shooting in
the foot with POSIX APIs that frequently use octal mode bits.
This change fixes a bug in opendir(".") on New Technology.
Lastly, redbean will now serve crash reports to private network IPs.
This is consistent with other frameworks. However that isn't served
to public IPs unless the -E flag is passed to redbean at startup.

This fixes a regression from a change a few weeks ago in git commit
af645fcbec which caused certificates to
not be free()'d correctly if the certificates are chained. dlmalloc()
should have printed an error in most build modes. ASAN caught it too.
