At least in neovim, `│vi:` is not recognized as a modeline because it
has no preceding whitespace. After fixing this, opening a file yields
an error because `net` is not an option. (`noet`, however, is.)
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
We can once again create 2mb statically-linked Python binaries:
$ make -j8 m=tiny o/tiny/examples/pyapp/pyapp.com
$ ls -hal o/tiny/examples/pyapp/pyapp.com
-rwxr-xr-x 1 jart jart 2.1M May 1 14:04 o/tiny/examples/pyapp/pyapp.com
$ o/tiny/examples/pyapp/pyapp.com
cosmopolitan is cool!
The regression was caused by Python thread support in b15f9eb58
- enable WITH_THREAD and _POSIX_THREADS
- add headers everywhere
- breaks only two tests (faulthandler and signal)
- disabled terminal completion because it causes segfaults for some
reason (probably could not get the current thread)
- add vdso dump utility
- tests now log stack usage
- rename g_ftrace to __ftrace
- make internal spinlocks go faster
- add conformant c11 atomics library
- function tracing now logs stack usage
- make function call tracing thread safe
- add -X unsecure (no ssl) mode to redbean
- munmap() has more consistent behavior now
- pacify fsync() calls on python unit tests
- make --strace flag work better in redbean
- start minimizing and documenting compiler flags
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
