We defined `noinline` as an abbreviation for the longer version
`__attribute__((__noinline__))` which caused name clashes since
third party codebases often write it as `__attribute__((noinline))`.
* Add GetBody() Lua API to redbean.
This improves consistency with RFC 7230 terminology and
should be favored over the old GetPayload function.
* Add GetStatus() API to redbean.
This is useful to get status after it's changed/set by Redbean,
for example if 505 or 508 is set when ServeRedirect is called.
* Introduce GetAssetComment() API to redbean.
This function should be favored over the old name GetComment().
* Introduce IsLoopbackClient() API to redbean
* Limit redbean reason to 128 chars when set instead of reporting an error
* Fix redbean re.NEWLINE documentation
* Add documentation for method and body parameters in redbean Fetch
* Add documentation for redbean ProgramAddr
* Update redbean SetHeader documentation to clarify behavior with Serve* calls
Cosmopolitan Threads are currently Linux-only (with some NetBSD
and Windows support too!). This change ensures we only initialize
the high-level threading runtime when Cosmopolitan Threads are used.
* Fix Lua panic in redbean when calling request/connection functions from .init.lua
The error calls were triggered appropriately, but used the global Lua
state instead of the current Lua state (within protected call), which
triggered Lua panic. This executes the error in the proper context.
* Rename global Lua state object to make its (mis-)usage easier to detect
* Fix redbean crash during redirect in debug logging mode
* Add reset for redirect loop check in redbean Route
Without this reset a combination of RoutePath() and Route() calls
could return "508 loop detected", since RoutePath could be called
twice for the same redirected path.
The protection against looping is still there, as it can only
loop inside the Route() call (as it always serves something).
* Update redbean redirect message for clarity
* get_exports_list should return list
* remove unintentional `CC=clang` in makefile
* avoid importing sysconfig during startup
site.py requires only a couple of functions from sysconfig, but needs to
load the entirety of sysconfig to get those functions. This commit
makes it such that sysconfig is imported only when sys.platform is darwin.
* remove redundant constants from stat module
The constants are only there in case the C implementation (ie the _stat
module) is not available. With Cosmopolitan the _stat module is always
available. The entire Lib/stat.py file can be removed if the Windows-based
constants can be moved into the Modules/_stat.c.
* minimal changes to os.py
python checks os-based assumptions at startup, some of which can be
bypassed since this is Cosmopolitan Python.
This commit makes numerous refinements to cosmopolitan memory handling.
The default stack size has been reduced from 2mb to 128kb. A new macro
is now provided so you can easily reconfigure the stack size to be any
value you want. Work around the breaking change by adding to your main:
STATIC_STACK_SIZE(0x00200000); // 2mb stack
If you're not sure how much stack you need, then you can use:
STATIC_YOINK("stack_usage_logging");
After which you can `sort -nr o/$MODE/stack.log`. Based on the unit test
suite, nothing in the Cosmopolitan repository (except for Python) needs
a stack size greater than 30kb. There are also new macros for detecting
the size and address of the stack at runtime, e.g. GetStackAddr(). We
also now support sigaltstack() so if you want to see nice looking crash
reports whenever a stack overflow happens, you can put this in main():
ShowCrashReports();
Under `make MODE=dbg` and `make MODE=asan` the unit testing framework
will now automatically print backtraces of memory allocations when
things like memory leaks happen. Bugs are now fixed in ASAN global
variable overrun detection. The memtrack and asan runtimes also handle
edge cases now. The new tools helped to identify a few memory leaks,
which are fixed by this change.
This change should fix an issue reported in #288 with ARG_MAX limits.
Fixing this doubled the performance of MKDEPS.COM and AR.COM yet again.
It's now possible to scroll panels is the TUI while the display
is blocked on input. INT 16h now translates UTF-8 to CP-437 and
displays unmappable characters using a lambda symbol. Bracketed
paste mode guards will also be filtered out.
- python now mixes audio 10x faster
- python octal notation is restored
- chibicc now builds code 3x faster
- chibicc now has help documentation
- chibicc can now generate basic python bindings
- linenoise now supports some paredit-like features
See #141
This program usually runs once at the begininng of each GNU Make
invocation. It generates an o//depend file with 170,000 lines of
Makefile code to define source -> headers relationships.
This change makes that take 650 milliseconds rather than 1,100ms
by improving the performance of strstr(), using longsort(), plus
migrating to the new append library.
The APE_NO_MODIFY_SELF loader payload has been moved out of the examples
folder and improved so that it works on BSD systems, and permits general
elf program headers. This brings its quality up enough that it should be
acceptable to use by default for many programs, e.g. Python, Lua, SQLite
and Python. It's the responsibility of the user to define an appropriate
TMPDIR if /tmp is considered an adversarial environment. Mac OS shall be
supported by APE_NO_MODIFY_SELF soon.
Fixes and improvements have been made to program_executable_name as it's
now the one true way to get the absolute path of the executing image.
This change fixes a memory leak in linenoise history loading, introduced
by performance optimizations in 51904e2687
This change fixes a longstanding regression with Mach system calls, that
23ae9dfceb back in February which impacted
our sched_yield() implementation, which is why no one noticed until now.
The Blinkenlights PC emulator has been improved. We now fix rendering on
XNU and BSD by not making the assumption that the kernel terminal driver
understands UTF8 since that seems to break its internal modeling of \r\n
which is now being addressed by using \e[𝑦H instead. The paneling is now
more compact in real mode so you won't need to make your font as tiny if
you're only emulating an 8086 program. The CLMUL ISA is now emulated too
This change also makes improvement to time. CLOCK_MONOTONIC now does the
right thing on Windows NT. The nanosecond time module functions added in
Python 3.7 have been backported.
This change doubles the performance of Argon2 password stretching simply
by not using its copy_block and xor_block helper functions, as they were
trivial to inline thus resulting in us needing to iterate over each 1024
byte block four fewer times.
This change makes code size improvements. _PyUnicode_ToNumeric() was 64k
in size and now it's 10k. The CJK codec lookup tables now use lazy delta
zigzag deflate (δzd) encoding which reduces their size from 600k to 200k
plus the code bloat caused by macro abuse in _decimal.c is now addressed
so our fully-loaded statically-linked hermetically-sealed Python virtual
interpreter container is now 9.4 megs in the default build mode and 5.5m
in MODE=tiny which leaves plenty of room for chibicc.
The pydoc web server now accommodates the use case of people who work by
SSH'ing into a different machine w/ python.com -m pydoc -p8080 -h0.0.0.0
Finally Python Capsulae delenda est and won't be supported in the future
PYOBJ.COM was failing when statically analyzing _pyio.py in MODE=dbg
because co_consts contained a big number, which dirtied the interpreter
exception state. We now do comprehensive error checking w/ Python API.
The -DSTACK_FRAME_UNLIMITED CPPFLAG has been removed from DES since its
self test function has been fixed to use heap memory rather than making
aggressive use of the stack.
This change also fixes a regression with function tracing (the --ftrace
flag a.k.a. ftrace_install() a.k.a. cosmo.ftrace) in ASAN build modes.
Lastly, the _tracemalloc module should now always be available for use
in MODE=dbg.
We remove (i.e. hide behind a debug ifdef) the recursion checking methods,
and the memory hooks and memory allocator methods. ASAN mode has no
PYMALLOC, so we need a macro. Fix build break with des.c stack allocation.
In Python, the zipimport path hook is usually the first entry in
sys.path_hooks, so that any zip files in sys.path can be handled
correctly. In the APE, the zipimport hook was removed because it was
relatively slow compared to Cosmopolitan when it came to handling
imports from the APE's internal zip store.
However, some python scripts (for example when pip installs some
packages) modify sys.path to consider a local zip file, and then attempt
to import from it. This change prevents potential "unable to import"
errors in such cases, so that Actually Portable Python can be more of a
drop-in improved replacement.

The `ape-no-modify-self.o` bootloader now has an mmap-based
payload that helps read-only APE binaries be load faster since it
doesn't need to copy any files.
This change reinvents all the GNU Readline features I discovered that I
couldn't live without, e.g. UTF-8, CTRL-R search and CTRL-Y yanking. It
now feels just as good in terms of user interface from the subconscious
workflow perspective. It's real nice to finally have an embeddable line
reader that's actually good with a 30 kb footprint and a bsd-2 license.
This change adds a directory to the examples folder, explaining how the
new Python compiler may be used. Some of the bugs with Python binaries
have been addressed but overall it's still a work in progress.
qjsc.com now has a -n do nothing flag so the makefile can create a
localized binary. See also #267 where we have an exciting new change
aiming to address this particular APE gotcha.
- Compile repl.js & qjscalc.js and include them in qjs.com zip
- Change quickjs-libc.c / js_os_poll to handle Windows console
This last change is needed because poll and select on Windows forbid
non-socket handles and Cosmopolitan Libc hasn't polyfilled that yet.
